VETERINARY INSTRUMENT.

SPECIFICATIONforming part of Letters Patent N o. 631,646, dated August 22, 1899., I Application iiled September 14, 1898. Serial No. 690,970. (No model.) 4

To all whom, it may concern.-

Be it known that I, JOHN LAUER, a citizen of the United States, residing at Moodyville, in the county of Pottawatomie and State of Kansas, have invented a new and useful Veterinary Instrument, of whichY the following is a specification.

My invention relates to veterinary instruments, and particularly to a device for removing obstacles from the throats'of cattle; and the object in view is to provide an apparatus of this class whereby obstacles in the throats of cattle may be dislodged ldownwardly or inwardly, and, furthermore,`to provide a device of such a construction as to relieve the stomachs of cattle suffering from wind-colic and analogous complaints.

Further objects and advantages of this Ainvention will appear in the following description and the novel features thereofA will be particularly pointed out in the appended claim. Y

In the drawings, Figure l is a view of an instrument constructed in accordance with my invention applied in the operative position. Fig. 2.is a detail view in perspective of the apparatus. Fig. 3is a partial sectional view of the same.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

The device embodying my invention consists, essentially, of a pliable tube 1, of rubber or analogous material of sufficient iiexibility to allow it to curve and accurately follow the curvature of the throat or alimentary canal of the animal, while sufficiently stift to resist transverse compression by the walls of the throat, and also to enable the operator by pushing axially thereon to advance the inner end toward the stomach of the stock. Carried by this tube at one end is a tip 2, also of tubular construction and having lateral and terminal vents 3 in communication with the bore of the'tube, the outer extremity of said tip being preferablyconcaved or dshed to form a cup, whereby in dislodging an obstacle from the throat of an animal the cup end may be brought into contact with the obstacle and insure the downward or inward movement thereof when the operator advances the tube inwardly. I also preferably serted. A v piece constitutes a gag and prevents the aniattach a terminally-converted tip 4. to the `other end of the tube, the same being p rovided with lateral and terminal vents 5,'and it will be understood that either tip may be used for insertion into the throat of the* animal `to dislodge an obstacle' and that while one tip is inserted the other` provides for the free passage of air into and out of the tube. I preferably construct the tips of hard rubber or equivalent material, and in order that an efficient connection between the same and the tubing may be secured I employ intermediate couplings 6, also of hard rubber or the equivalentthereof, said couplings being provided with nipples for insertion into the ends of the rubber tubing and to which said rubber tubing may be permanently attached. The couplings are also preferably provided with sockets for the reception of reduced portions of nipples 7 on the tips.

In connection withA the abovedescribed members of the apparatus I employ a mouthpiece 8, consisting of a cross head or block,

fastening devices, such as a buckle l1 and tongue-perforations l2. The object of this fastening device is to secure the mouthpiece in the mouth of the animal, and in the center of the mouthpiece is formed a guide-perforation 13, through which the tubing is in- It will be understood that the mouthmal frompclosingthe teeth upon the rubber' tubing and otherwise interfering with the manipulation of the device.

It will be understood from the foregoing description that the apparatus embodying my invention is designed to dislodge an obstacle downwardly or inwardly, and this operation is preferable in the first place because it can usually be accomplished with greater facility than a dislodgment upwardly or outwardly in that it is not necessary to engagethe apparatus with the obstacle. It frequently happens that the obstacle is of such a material IOO as to make it diiiicult to accomplish a sufficientlypositivc engagement to enable the operator to withdraw it outwardly from the throat, and to remove it piecemeal occupies a considerable length of time and the animal is liable to succumb from loss of breath or otherwise before the object is accomplished. Furthermore, the obstacle can be more readily displaced inwardly or downwardly than in the opposite direction, and when it reaches the stomach of the animal it is not liable to cause furtherinconvenience. IIence the necessity for entirely removing the same is avoided. Furthermore, by providing an instrument adapted to move an obstacle inwardly or downwardlyI am enabled to use a flexible tubing adapted for closely following the curvature of the passage through which it passes and avoid the use of a sharp or rough tip liable to abrade the walls of the passage. I have found in practice that sufficient force can be applied to a tubing of first-quality hose to dislodge any obstacle from the throat of an animal without inconvenience to the latter, and even should the operation occupy a considerable length of time I have provided for the continuous breathing of the animal, and hence for the successful termination of the operation. The air passage or canal in the instrument is continuous, one end thereof being permanently outside of the mouth of the animal, and it will be understood that the access of air facilitates the inward dislodgment of the obstacle. Obviously as the obstacle moves inwardly it will necessitate an in Ilux of air to occupy the space vacated thereby, and this air is supplied through the tubing.

A further advantage of the construction described residesints use in connection with cattle suffering from bloat or wind-colic. By introducing one end of the tubing into the stomach of the animal a direct outlet is provided for the wind and the relief is immediate.

It will be understood, furthermore, that various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the spirit or sacriiicing any of the advantages of this invention.

Having described my invention, what I claim is- In a Veterinary instrument, the combination with a gag comprising a central perforated portion and having diminished ends provided wit-hattaching-straps pivoted thereto to permit a rocking motion of the gag with respect to the straps, and a flexible and extensible tube slidably mounted in said perforation and having terminal tips provided with axial and radial openings, one of said tips having a concaved end and the other tip having a convex end.

In testimony that I claim the foregoing asl myown I have hereto affixed my signature in the presence of two witnesses.
