SPECIFICATION forming part of Letters Patent No. 686,578, dated November 12, 1901.

Application 'filed March 26, 1901. Serial No. 52,937. (No model.)

To all whom it may conccrm.

Be it known that I, DAVID FREDERICK Bow- ERSOX, a citizen of the United States, and a resident of Aaronsburg, in the county of Center and State of Pennsylvania, have invented new and useful Improvements in Forceps, of which the following is a full, clear, and exact description. c

This invention relates to forceps designed especially for veterinary use in performing operations in the esophagus of animals. It embodies certain features of construction by which I am enabled effectively and easily to perform this work without in any way endangering the animal by laceration.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side View of my invention with device, and Fig. 3 is a similar view of theinner portion.

0. indicates the jaws of the apparatus which may, if desired, be serrated on their inner faces and which have their points turned inward to more efiectively engage the object to be removed. These jaws are pivoted within a cavity 12, formed in a holder b, the pivots and the inner ends of the jaws being so arranged that it will be impossible to lacerate the throat of an animal by the movement of the jaws. A spring 0 is employed to spread the jaws normally apart, and the jaws have a toggle a connected thereto, by which they may be moved together through the medium of other devices which will be hereinafter described.

The stock of the forceps may be of any length suitable to the nature of the work to be performed. It is formed of a flexible structure made up of an exterior casing 01, preferably of leather, within which is arranged a coil-spring d. The jaw-holder'b is arranged at the outer end of the stock and has a tubular extension 6 projected thereinto. At the inner end of the stock (see Fig. 3) the stock has a terminal block (1 with which the spring d and exterior casing d are engaged. This block (1 has a tubular extension 61 projecting 'into the stock, and between these two tubu lar extensions 6 and d longitudinally-extending wires (1 are passed, such wires serving to hold together the parts of the stock and to make up the flexible structure thereof.

6 represents the handle of the apparatus, which may be of any form desired. This handle is constructed with a cavity e therein, in which is arranged the part f of the operating-lever f. This operating-lever lies on the outside of the handle and is movable, as indicated by the dotted lines in Fig. 3. Connected with the part f of the lever f is a coupling f to which a wire f is connected, and this wire passes completely through the stock and is joined to a coupling 1, connected in turn with the toggle e. The spring a normally throws the jaws open and causes the lever f to assume the position shown in I Fig. 3. By pressing the lever f toward the handle a the toggle a may be broken and the jaws a forced together, as shown by dotted lines in Fig. 2. V

In using the device the lever f may be depressed to close the jaws, and then the forceps may be inserted into the passage in which the operation is to be performed. When the forceps have been placed in the proper position, the spring 0 will be operated to open the jaws, and then upon again operating the lever f the jaws may be closed into active position.

The uses and advantages of my invention will be apparent to persons skilled in the art, and further comment on these parts will not be necessary.

Various changes in the form, proportions, and minor details may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- l.
