Specification forming part of Letters Patent No. GO dated May 16 1865.
To all whom it may concern:
Be it known that I C. H. WILDER of Argyle in the county of Lafayette and State of Wisconsin have invented a new and Improved Breast Pump and I do hereby declare that the following is a full clear and exact description thereof which will enable others skilled ill the art to make and use the same reference being had to the accompanying drawings forming a part of this specification in which
Figure 1 is a longitudinal central section of this invention. Fig. 2 is a plan or top view of the same.
Similar letters of reference indicate like parts.
This invention consists in the application to the mouth of ‘a breast pump of a supporting screen in such a manner that the air is brought to act direct upon the end of the nipple and upon every natural course through which the milk can be drawn and all undue strain on any part of said nipple is avoided.
The invention consists further in the employment or use of an extension piece in combination with the supporting screen applied to the end of the suction pipe of a breast pump in such a manner that the instrument can be accommodated to nipples of different length by adjusting the extension piece and that the pump can be operated without pain in all cases.
A represents the elastic or India rubber bulb which forms the working part of an ordinary breast pump and which is secured to the end of the suction pipe B by a cord or any other suitable means in the usual manner. The outer end of the suction pipe is covered by a screen which may be made of wire gauze or any other suitable material separate and distinct from the pipe or it may be made solid with said pipe and perforated with small holes. This screen is made concave to correspond to the end of the nipples with which it comes in contact and when the pump is in operation it supports the nipple and causes the air to act direct upon the end of the nipple and upon every natural course through which the milk can be drawn. The mouthpiece D of the suction pipe is attached to said pipe so that it can be extended and adjusted in relation to the supporting screen according to the size of the nipple on which the pump is intended to operate. Said mouthpiece may either be arranged so that it will slide in and out on. the end of the suction pipe or it may be applied with a screw thread or in any other suitable manner which will allow of elongating or shortening said mouthpiece. If it is made to slide in and out suitable packing of India rubber or other substance or material mast be applied to rend the joint airtight.
In order to operate the pump it is applied to the breast in the ordinary manner and the month piece is drawn out until the nipple just touches the supporting screen. When the pump is put in operation the nipple draws out gradually and the mouthpiece is elongated as much as can be done without producing pain.
By the supporting screen the trouble of a broken breast is saved to the patient and the pump can be used to the best advantage. The screen brings the air to act upon every natural course through which the milk can be drawn and the pump can be easily adjusted to nipples of different size.
This attachment to a breast pump is cheap simple not liable to get out of order and it increases the power and usefulness of the pump very materially.
I claim as new and desire to secure by Letters Patent
1. The application to the mouth of a breast pump of a supporting screen constructed and operating substantially in the manner and for the purpose set forth.
2. The employment or use of an extension mouthpiece D applied in combination with the supporting screen and with the suction pipe of a breast pump substantially in the manner and for the purpose described.

UNITED STATES PATENT OFFICE.
UBERTO DESAIX EZELL OF KIMBALL TEXAS.
BREASTPUMP. Specification of Letters Patent. Patented Sept. 5 1905.
Application filed November 21 1904 Serial No.
To cat whom it may coitoel'it:
Be it known that I UBEBTO DESAIX EZPLL a citizen of the United States residing at Kimball in the county of Bosque and State of Texas have invented new and useful improvements in Breast Pumps of which the following is a specification.
This invention relates to improvements in breast pumps the object of the same being to provide a device of this character by which the suckling of an infant may be closely simulated and the extracting action rendered more efficient and natural and less liable to injure the secreting glands and which may be conveniently operated by the patient or nurse or other attendant.
With these and other objects in view the invention resides in the combination and arrangement of parts as hereinafter described and claimed reference being had to the accompanying drawings in which Figure 1 is a perspective view of a breastpump embodying my invention. Fig. 2 is a vertical longitudinal section of the same showing the normal and compressed positions of the nipple manipulator in full and broken lines and Fig. 3 is a detail perspective view of the nipple manipulator detached.
Referring now more particularly to the drawings the numeral 1 represents a cupshaped applicator adapted to be applied to the gland and to snugly and easily fit the same. This applicator is preferably formed of rubber and is provided upon its convex side with an outwardly projecting neck or sleeve 2 preferably of pyramidal form and corn posed of rubber or other suitable elastic material. This neck or sleeve receives the outer end or throat 3 of an extracting tube 4 which is connected at its outer end to an extractor 5. The throat 3 conforms in contour to the shape of the neck or sleeve 2—that is the said throat is substantially of pyramidal form—so that its upper and lower sides will conform to the flare of the corresponding portions of the neck or sleeve 2 and extend parallel therewith in order to enable the nipple manipulating device to be inserted for operation as hereinafter described.
The extractor 5 comprises a pump cylinder 6 having a tapered inner end 7 over which is fitted the inner enlarged or flared end 8 of the extracting. tube 4 thus detachably connecting the pump to said tube. In th6 cylinder 6 is a piston 9 which is provided with suitable packing to tightly lit the interior of said cylinder and connected to said piston is a stem 10 projecting to the exterior through a plug or cap 11 closing the outer end of the cylinder and provided at its outer end with 6o a knob or finger piece 12 whereby it may be operated to reciprocate the piston in the cylinder for extracting purposes. The stern 10 is screw threaded substantially throughout its entire length and on the outer end of the stem is a stop disk or head 13 having an internally screw threaded bore to fit the threads on the stem and adapt said disk to be adjusted thereon to limit the inward movement of the piston. By the provision of this stop disk the piston when drawn out to create a vacuum in the cylinder and extracting tube to effect the extraction of milk from the gland may be locked or held immovable at the outer end of the cylinder by adjusting the stop disk on the screw threads of the stem until said disk abuts against the cap or plug 11. When the device is applied for use it will be understood that the outward movement of the piston effects the extraction of the secretion which may be so removed from the pump cylinder by detaching the pump from the extracting tube 4.
In order to render the extracting action more efficient and natural and less liable to injure the gland a nipple manipulating device is provided which may be operated simultaneously with the extractor to simulate as closely as possible the suckling action of the lips of the infant on the nipple. This device comprises a pair of lips or fingers 11 90 which are disposed between the upper and lower flaring sides of the neck or sleeve 2 and the corresponding adjacent sides of the throat 3 and are formed with outwardly bent or divergent ends 15 which closely conform to the contour of the inner end of the neck or sleeve 2 at its junction with the cup 1 and are adapted to be moved toward and from one another to compress and release the nipple and thereby simulate the natural action of the lips of the child. The lips or fingers extend rearwardly beyond the throat 3 and are connected to operating levers 17 which extend at an outward angle or in divergent relation beyond the neck 2 on opposite sides of the extracting tube 4 and terminate at their outer ends in finger pieces 18 by which they may be compressed to the dotted line position shown in Fig. 2 to expand the lips or fingers. The lips or lingers are normally retained in closed position that is in the adjacent position shown in Fig. 2 in which they are adapted to effect the compression of the nipple by the elasticity or resiliency of the upper and lower flaring sides of the pyramidal neck or sleeve 2 which also operate to maintain the levers in the divergent relation shown in said figure. The levers are provided at their forward ends with ears 19 which are connected by suitable pivot pins 20 by which they are mounted to have relative swinging movement to operate the lips 14. When the levers are pressed by the action of the fingers on the finger pieces 18 to the dotted line position shown in Fig. 2 the lips 14 are forced apart and the sides of the neck or sleeve 2 expanded to accommodate this movement. This action of the fingers releases the nipple as will be readily understood and compression of the nipple is effected by releasing the levers so that the lips will be retracted by the resilient action of the sides of the neck or sleeve in returning to their normal positions. By thus alternately compressing and releasing the levers the lips will be alternately expanded and contracted or closed together so that the nipple will be compressed and released in a manner readily understood to simulate the natural action of the infant in extracting the fluid.
In the operation of the device the cup or applicator 1 is applied to the gland and the lips expanded to engage the nipple and simultaneously with the operation of the levers to force the lips apart the pump piston 9 is
operated to extract the fluid. This operation 35 is continued until the cylinder 6 is filled where upon the stop disk 13 is adjusted on the piston stem to hold the piston against inward movement. The pump may then be detached to discharge the extracted fluid as will be 40 readily understood.
In practice the pumpcylinder and piston may be made of vulcanite fiber or of glass or of any other suitable material to serve the purpose. From the foregoing description taken in connection with the accompanying drawings the construction and mode of operation of the device will be readily understood and it will I be seen that it provides an extracting apparatus which is simple of construction efficient 1 in use and capable of being readily cleansed and which further simulates the natural extracting action to a marked extent.
Having thus described the invention what is claimed as new is
1. In a device of the character described the combination of an applicator nipple manipulating fingers means for operating said fingers and an extractor in communication with the applicator.
2. In a device of the character described an applicator having a neck or sleeve adapted to expand and contract an extractor having a throat communicating therewith nipple manipulating fingers extending through the neck or sleeve into the applicator.

MILK-CATCHER FOR NURSING-WOMEN.
SPECIFICATION forming part of Letters Patent No. dated April 8 1884.
Application filed July 20 1883. (No model.)
To all whom it may concern
Be it known that I LYDIA EMELINE PATTEE a citizen of the United States residing at Smith Centre in the county of Smith and State of
5 Kansas have invented certain new and useful Improvements in Milk-Catchers for Nursing-Women; and I do hereby declare the following to be a full clear and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in milk-catchers for nursing-women and has for its objects to prevent the milk from wetting the clothing and to improve the form. These objects are attained by the apparatus illustrated in the accompanying drawings forming a part of this specification in which Figure 1 is an elevation taken from the side next the body. Fig. 2 is a front elevation. Fig. 3 is a sectional view. Fig. 4 is a view showing the milk-catchers or protectors adjusted to the person.
The letter A represents the convex side of the protector. B is the concave side. b b' are
short straps having button-holes. e e are elastic straps passing over the shoulders and connected to each other by the strap f. The straps e e are provided with fiat buttons which are buttoned to the short straps b whereby the breast - protectors are suspended. The shoulder-straps e e are attached to the belt E at the back. e' e' are short straps having flat buttons which are buttoned to the short straps b' b'. The lower ends of straps e' e' are attached to the belt E whereby the breast-protectors are held down and retained in the proper position on the body of the wearer. The belt E is fastened by a button in front or in any other convenient manner. a is an orfice to receive the nipple and is placed on the concave surface of the protector.
I prefer to make the protectors of white rubber or gutta-percha the same material of which are made the bulbs of breast-pumps and 45 the nipples of nursery -bottles. As this is flexible it will not bruise the breast and has this advantage over a breast- protector made of any rigid substance such as glass; and the manner of fastening it to the body of the wearer so enables it to be kept in place without any hard pressure on the breast.
The letter C indicates a small orifice for emptying the contents of the breast-protector. Having described my invention what I desire to claim and secure by Letters Patent is In a milk-catcher for nursing-women the protector A having concave side B orifice a and orifice C made of flexible material and provided with short button-hole straps b b' in combination with elastic straps e e having cross-strap f and straps e' attached to the belt E as shown and described and for the purposes set forth.
In testimony whereof I affix my signature in 65 presence of two witnesses.

BREAST PUMP

ANAXIMANDER B. TUTTON OF SIOUX FALLS DAKOTA TERRITORY.
BREASTPUMP.
SPECIFICATION forming part of Letters Patent No. dated April 26 1887.
Application filed July 8 1886. Serial No. . (No model.)
To all whom it may concern:
Be it known that I ANAXIMANDER B. Tutton of Sioux Falls in the county of Minnehaha Dakota Territory have invented an Improved Breast Pump of which the following is a specification.
My invention is in the nature of an improved breas pump.
Numerous forms of breastpumps have been devised for this purpose all of which are more or less objectionable in consequence of their severe mechanical action and their irregular pulsating strain. In most cases the vacuum chamber is a compressible elastic bulb which in expanding exerts its full suction upon the breast and this too in an intermittent manner.
In my breast pump the full force of the suction is exerted not upon the breast alone but partly upon a waterleg or column of water and milk in a long siphon tube which modifies its effect on the breast while the pulsations of the bulb are broken up and rendered more like a uniform suction the waterleg exerting a pull upon the breast in the interval of compressing the bulb which makes the suction on the breast continuous and prevents the nipple socket from becoming detached from the breast in said intervals of compression of the bulb.
Figure 1 is a perspective view illustrating the application and use of my invention and Fig. 2 is a side view partly in section of the breast pump.
In the drawings A is a bell shaped socket or cap adapted at its larger end to fit against the breast of the woman and to inclose the nipple of that breast. The smaller end of this socket A opens into a tube B near one end of that tube. On the end of tube B nearest to. socket A is an elastic bulb C or suction chain the other (or lower) end of tube B being open. The tube B is a flexible rubber tube and when in use occupies the pendent position shown in Fig. 1.
The manner of operation is as follows: The socket A is held against the breast of the woman so as to inclose the nipple and with sufficient pressure to prevent air from entering between the rim of A and the skin of the woman's breast. The lower end of tube B is then submerged in water or other liquid of proper temperature contained in a basin or other vessel.
The bulb C is then compressed and allowed to expand which action of expansion sucks water (preferably warm) or other liquid from the basin into the tube B and through it into socket A and into bulb C. The water or other liquid thus furnished to socket A fills that socket and immerses the woman's nipple inclosed therein. Then bulb C is alternately compressed and allowed to expand the lower end of tube B being during the operation always submerged in the liquid in the basin and the socket A being during the operation always pressed against the breast with sufficient pressure to prevent air from entering 65 socket A between its rim and the skin of the woman's breast. It is obvious that if the socket A were a perfect bulb or chamber or had its larger end closed with an inflexible material and were then filled with water the tube B and the bulb C at the same time containing water then neither the compression nor the expansion of bulb C could remove by suction any of the water from such a bulb or chamber although the stress of the suction would apply upon the water in such a bulb or chamber and through the water upon the sides of the inside of such a bulb or chamber. This principle acting in my device serves to keep socket A (when once filled) full during the entire operation thus providing a constant immersion of the woman's nipple in water or other fluid during the entire operation for in my device the compression and expansion of bulb C and the flow of water or other liquid through tube B together with the weight of the column of water or other fluid in siphon tube B creates a suction force acting upon the water or other liquid in socket A and through that liquid upon all parts interior to socket A and therefore upon the nipple and ends of the lactiferous ducts of the woman. This suction force draws milk from the lactiferous ducts into socket A releases a corresponding quantity of water or other liquid from socket A which flows there from into tube B and mixing with the water or other liquid in tube B is finally discharged there from into the basin and this operation continues as long as the device is in position and in operation too socket A however remaining filled.
It is obvious in the operation of my device that however strong the expansive force of bulb C may be its force acting upon the nipple and the human parts inclosed in socket A is measured and tempered by the height of the column of water or other liquid in tube B and this height may be increased or diminished by lowering or raising the basin and the end of tube B therein and this tempering of the expansive force of bulb C to suit various degrees of tenderness in the human parts is one of the advantages of my device. If however at any time it be desirable to allow bulb C to exert its whole force upon the human parts it is only necessary (after compressing Instead of the expansible and compressible bulb C) to pinch or otherwise close tube B 1 bulb C any

other form of suctionchamber may be used.
Having thus described my invention what I claim as new is a breastpump consisting of a relatively long tube B a nipple socket A opening into the same and a compressible and expansible bulb or suction chamber communicating with
child is incompetent and in cases where al the nipple socket and tube at the upper end though there is a competent child yet the of the latter the said tube nipple socket and mother being diseased it is desirable to waste 1 bulb being always in free and open communication without valve or obstructions to interfere with the oscillation of the liquid column substantially as shown and described. and while tube B is so closed to allow bulb C to expand and this too while the woman's nipple is submerged in the water or other liquid in socket A. Another advantage is in the use of warmth
and moisture in the operation of milking a woman where there is no child or where the milk for the application of warmth and moisture to the nipple closely simulates the
natural warmth and moisture of a child's mouth and brings the nipple and the milk
organs into the natural conditions for milk giving because such warmth and moisture dissolves the dry accumulations of pus or fever product softens the hardened openings and relaxes the strictured lactiferous ducts and prepares them for the easier extraction of milk.
I am aware that other breast pumps are known and used—such for instance as are shown in Patents Nos. and . In the first of these the valves preclude the oscillation of the liquid column. In No. the suction chamber is at the bottom and cannot lift or oscillate the liquid column and in No. there is no such relation of siphon tube and suction chamber which could permit the same action to occur as in my invention.
