STOMACH=PUMFL SPECIFICATION forming part of Letters Patent No. 686,281 dated November 12, 1901. Application filed May 28, 1901. Serial No. 62,223. (Nomorleh) To aZZ whom it may concern.-

Be it known that I, WAITE GERRY, a citizen of the United States, residing at Ventura, in the county of Ventura and State of Galifornia, have invented certain new and useful Improvements in Stomach-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in stomach-pumps 5 and its primary object is to provide an attachment whereby the tube of the pump may be readily swallowed without either buckling or slipping outward during such action. v

With these and other objects in view the invention consists in providing a knob of suitable material, such as soft rubber, which is connected to the end of the pump-tube by means of a cord formed with or secured to.

both the tube and knob.

The invention also consists in the novel construction and combination of parts herein after more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of myinvention, and in whicl1-- Figure 1 shows a pump with the attachment formed thereto. Fig. 2 is a detail view of the attachment and showing in section its point of connection with the tube. Fig. 3 is a detail view of a modified form of attachment.

It has been found in the use of stomachpumps that the tube when inserted into the throat has a tendency to buckle up during the act of swallowing. Moreover, the muscles of the throat fail to grasp the tube firmly, and as a result the same will slip outward under a very slight pull thereon. To overcome these objections, I provide an attachment which may be formed with the tubes of stomach-pumps or may be connected to pumps now in use. This attachment comprises a small knob 1, preferably substantially pear-shaped and formed of any suit able material, such as rubber. A flexible stem 2 connects the small end of the knob with the end 8 of the pump 4, and this stem is preferably formed integral with the tube and knob.

In Fig. 3 I have shown a modified form of attachment which can be detachably secured to a pump-tube. This comprises the knob 1 and a strong cord 5, which is passed through small apertures 6 and 7 in the knob and tube, respectively, and tied.

In use the knob 1 is placed in the throat and is firmly clasped and nearly surrounded by the muscles of the throat during the act of swallowing. The knob is drawn downward by the muscles and pulls the tube after it, thereby preventing buckling of the tube. Moreover, as the throat-muscles extend over the knob it is prevented from accidentally slipping outward;

In the foregoing description I have shown the preferred forms of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore re serve the right to make such changes as fairly fall within the scope of my invention.

I claim 1. In a stomach-pump, the combination with a tube; of a knob having a reduced portion, and a cord secured to said reduced portion and to the end of the tube.

2. In a stomach-pump, the combination with a tube; of a solid knob, and a cord connecting the knob to the end of the tube, said cord passing through apertures in the knob and in the closed end of the tube.

In testimony whereof I aifix my signature in presence of two witnesses.
