SPECIFICATION forming part of Letters Patent No, 340,739, dated April 2"], 1886.

Application filed January 2, 1886. Serial No. 187,333. (Nomodehl To all whom it may concern.-

Be it known that I, FREDERICK A. S'rorIL- MANN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Exhausting and Forcing Apparatus for Stomach-Pumps, &c., of which the following is a specification.

My invention relates to an exhausting and forcing apparatus for stomach-pumps, 850.,

[O that is adapted to injecting into the stomach or other place any desired liquid from the receptacle in which it is held, and also to exhausting from the stomach or other place, whatever the contents may be, and discharg I 5 ing the same into a suitable receptacle.

My invention consists of an exhausting and forcing apparatus composed of a suction and forcing bulb of rubber connected to a circular disk or valve base, and having openings and valves working in opposite directions. The rubber tube to be placed into the stomach and the rubber tube to be placed into a receptacle are both connected to a circular disk, and this disk is held against the surface of the afore- 2 5 said valve-disk by a central connecting-screw or similar fastening in such manner that if the tube'disk is held in one hand and the forcingbulb turned by the other hand, or vice versa, a half-revolution, the position of the valves 0 in their relation to the two tubes is reversed, so as to enable the user to inject liquid into the stomach from a basin or receptacle, or to exhaust the contents of the stomach and discharge the same into the basin.

5 In the drawings, Figure 1 is an elevation,

partially in section, of my improved exhausting and forcing apparatus. Fig. 2 is a plan of the upper surface of the valve-disk. Fig. 3 is an inverted plan of the under surface of the valve-disk; and Fig. 4 is a plan of the tubedisk.

A is the rubber exhausting and forcing bulb; B, the valve-base; C, the tube-disk; D, the stomach-tube, and E the tube, upon the 5 end of which is the usual cup, 1, adapted to being placed in a liquid-holding basin or receptacle.

The bulb A and rubber tubes D and E are of the usual character.

The bulb A and valve-base B are firmly connected by wiring or tying the mouth of the former around the periphery of the valve-base.

The valve-base B is preferably made of hard rubber, although other 1naterialssuch as metal, celluloid, or woodmight be used, and 5 said base is made with the passageways a I) through it, and a valve, a, secured to and seated upon the upper surface of the base, and the valve d secured within a valve-chamber in said base and seated against an under surface, 2.

The valves 0 and d are preferably secured by screws, so as to be removable, and they operate in opposite directions.

The valvebase B has around its under sur- 6 5 face the rim e, and the disk Ofits within such rim 0 and tightly against the surface of the valve-base B, and said parts are connected together by the screw or equivalent device,- which will permit of their being turned one upon the other in shifting the position of the valves in relation to the pipes D E. There is a pin, 3, in the circumference of the disk O,

and a portion .or about one-half of the circumference of the rim 6 is cut away, forming 7 a notch in which the pin 3 moves to limit the half-revolution of the bulb A and valve-base B. There are tubes 1 g projecting from the disk 0, to which the tubes D E are connected.

The sides of the bulb A may be marked 8 with the words Inject and Exhaust, accompanied with arrows to denote the direc-- tion of flow of the liquid, and in the position shown in Fig. 1 the pump is set to exhaust from the stomach or other place and discharge 8 through the pipe E. By forcing the air from the bulb A through the tube E a partial vacuum is formed, which, upon releasing the bulb, causes the liquid to How through tube D into the bulb A, and the liquid is ejected go through the tube E by squeezing the bulb. If now the bulb A and valvebase B are given a half-revolution, bringing the valve 0 over the tubes and E and the valve (1 over the tubes 9 and D, the position and operations are reversed and liquid can be drawn from a receptacle through the tube E into the bulb A, and then forced through the tube D into the stomach.

In place of the bulb A, I might employ a and disk 0, removabl y connected to each other,

the valves 0 (Z upon the valve-base B, and acting in opposite directions, the rim 6 upon the disk B, and partially removed to form a slot, the pin 3, to limit the movement of one disk upon the other and determine the position of the valves in relation to the tubes, substantially as specified.

2. An exhausting and forcing apparatus hav- 7 ing a valve-base and seats and valves working in opposite directions, in combination with a .disk and tubes connected therewith, and

means, substantially as specified, for connecting the disk to the valve-base, so that the relative positions of the tubes and valves can be reversed, substantially as specified.

Signed by me this 28th day of December, A. D. 1885.
