Specification forming part of Letters Patent No. 37,677, dated February 17, 1863. v l

To all whom it may concern;

Be it known that I, L. O. GOLVIN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Breast-Pump; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this speciication, in which- Figure'l is a vertical section of my invention, taken in the line x x, Fig. 2 5 Fig. 2, a side view of the same; Fig. 3, a horizontal section of the same, looking upward, yy, Fig. 1, indicating the plane of section Fig. 4, a section of a portion of the same, taken in the line z z, Fig. l.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in attaching a milkreceptacle, of glass or other suitable material, to a pump constructed and operated in a novel way, and provided with a nipple-tube of peculiar construction, all being arranged in such a manner that the device will be underthe complete control of the operator, and the suction or drawregulated with the greatest nicety to suit the convenience of the latter.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents a cup, which may be constructed of sheet metal and of bell shape or daring form. The bottom of this cup is provided with a valve, B, opening downward, and around the lower edge of the cup there is permanently attached a horizontal flange, a, the outer edge of which is provided with two lips, b b, the latter being bent down and undernea-th the main portion, to form hooks or catches to hold a milk-receptacle to the cup.

Gis the milk-receptacle, which may be of glass or other material, glass being preferable. The upper edge of this milk-receptacle is formed with a catch, c, to catch under the lips b b of the cup A, said ange having two notches or recesses, d d, made in it to allow the lips b b to pass into, so that they may catch over the liange c by turning the receptacle C. (See Fig. 3.) This arrangement or means for connecting the milk-receptacle C to the cup A is not designed to form an air-tight attachment-in fact, it should not be airtight-the means'bein g intended to serveonly as/a connection which will not admit of the two parts being casually detached, and at the Isame time admit of them being held in proper position in contact with each other. To the side of the cup A there is attached a short horizontal tube, D, which has a circular flange, l

d, upon it, said flange having two notches, e e, in it to admit of the two hooks ff, which are attached to a ring, g, or a nipple-tube, E, being fitted on the ange d. (See Fig. 4.) This arrangement serves as a means for attachin g the nipple-tube E to the tube D. The nipple-tube E is constructed of india-rubber, and has a spiral wire, e", within it, as shown in Fig. l. The nipple-tube is made of such a size as to t snugly on the nipple.

F is a handle, which is attached permanently to the cup A, and has an eye or loop, cxx, at its outer end, to admit of one or more of the fingers of the hand of the operator being passed through it.

Gr is alever, which is connected to the handle F, near the cup A, by a fulcrum-pinfX. This lever G has an eye or loop, fx", at its outer end, to admit of the thumb of the operator passing through it. The front end of the lever G is slightly curved, so as to it into an eye, lil, which is attachedto the center of a circular piece of india-rubber or other flexible material, I, the latter having a circular Wire, h, iitted in its end. This wire 7L is sprung within a iiange, fi, which is attached to the upper end ofthe cup A. The wire l1, retains or holds the india-rubber or other leXible material, I, on the top of the cup A, and the former serves as a piston to form a vacuum in A and draw the milk from the nipple and to force the milk into the receptacle C, the valve B, opening as the piston is forced down under the action of the lever G.

By this device it will be seen that the operator can regulate the suction with the great est nicety, so as to avoid all pain or inconvenience, for the operation of the lever Gr can be modified as desired. In forcing the milk down into the receptacle O the air therein passes out at the connection formed between said receptacle and the cup A, that connection not being air-tight, as previously stated.

Whenever the device requires to loe cleansed, all the parts are rendered accessible. The

nipple-tube E may be readily detached from the tube D, the piston I easily removed from the top of the cup A, and the milk-receptacle U readily detached from the cup A. The Whole arrangement is simple, and may be constructed at a small cost, and will operate efciently when constructed of small dimension-s. It also possesses the advantage of being applied and operated with facility by the female from Whom the milk is to b'edrawn. By having the nipple-tube E constructed with a spiral wire, h, the former is madel to act upon the nipple in the most favorable manner for' the abstraction of the milk. A nipple-tube coii structed solely of rubber would be too flexible, and would under the suction be liable to
