CAPONIZING INSTRUMENT Application filed September This invention relates to caponizing instruments of the class adapted for use in extract ing testicles of fowls.

The primary object of the present inven t-ion is to provide an instrument of the above kind which is extremely simple and durable in construction as well as efficient in use.

A further object is to provide an instrument of the kind specified which may be readily held steady while performing the 0 operation, and by means of which a firm grip may be had on the cord so as to insure removal of all of the testicle without danger of rupture.

Another object is to provide a caponizing instrument which may be effectively operated by one hand, so as to leave the other hand free to hold the fowl and which will allow clear vision and ready engagement of the jaws with the cord, so that the testicle may be extracted with ease and without requiring a large incision. 7

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing:

Figure 1 is a side elevational view of a caponizing instrument constructed 4 in accordance with the present invention;

Figure 2 is a top plan view thereof, and

Figure 8 is an enlarged developed fragmentary perspective view showing the aws and adjacent parts.

Referring more in detail to the drawing, the present instrument embodies a handle 1ncluding a rod 5 provided at one end with a depending hand grip 6, preferably in the form of an elongated loop integral with the rod 5, and provided at its other end wlth an open substantially triangular jaw 7, the plane of which is at right angles to that of the hand grip 6. The jaw 7 is preferably lntegrally joined at its apex to the rod 5 so as to present a transverse gripping bar portion 8 at its free forward or outer end, and as shown clearly in Figure 1, the jaw 7 extends forwardly and upwardly from the -rod 5,at anobtuse 10, 1927'.

angle. By reason of this construction and ar rangement, the testicle may readily fall with 111 the open center of the jaw, and clear vision along the top of the instrument is allowed-for permittlng the jaw to be properly directed Wltll'QZlSG in a comparatively small incision.

Pivoted to the forward or outer end of the rod or bar 5 is a vertically swinging jaw 9 arranged to overlie and move toward and away from the jaw 7. The jaw 9-is substantially of the same form'as aw 7 so as to pre- I sent a transverse bar portion 10 and adapted to cooperate with'the bar portion 8 of jaw 7 to grip the cord at a point between the inner end of the cord and the testicle. Pivotedto the rod5 is a-t-rigger 11 arranged to swing in a vertical plane adjacent to'but forwardly of the hand grip 6, the trigger having a suitable finger piece or ri-ng 12 on'its lower end and having'its upper end operatively connected to the aw 9 by means of a link 13 extending along and directly above the upper edge of the rod 5. The link 13 is connected to the jaw 9 forwardly of and above its pivot 14, and by pressing forwardly on the lower end of the trigger, the jaw 9 may be swung upwardly away from the jaw 7 as shown by dotted lines. in Figure 1, thus allowing the testicle to fall directly between and within the jaws. By then pressing rearwardly on the lower end of the trigger, the cross bar portions 8 and 10 may be caused to firmly grip the cord so that the testicle may be readily removed without danger of rupture. The jaws will, of course, be closed when inserting them in the incision, and by reason of their form and arrangement, the incision need not be large. The jaw 9 is preferably divided at its apex to provide side legs 15 whose free ends are pivoted to and engage opposite sides of the bar 5, and connecting these legs forwardly of the pivot 14 is a cross bar 16 with which the forward end of the link 13 is pivotally engaged.

Obviously, the trigger may be operated by a finger of the hand gripping the hand grip 6, thereby leaving the other hand of the user free to hold the fowl.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

It is possible to remove both testicles through one incision by means of the present instrument, without danger of rupturing the artery or the small blood vessels.

What I claim as new is:

A caponizing instrument comprising an elongated member, a hand grip depending from its rear end, a stationary jaw of substantially triangular shaped formation fixedly attached at its apex to the forward end of the elongated member and disposed upwardly at an obtuse angle with respect thereto, the central portion of the triangular shaped jaw being cut out, a coacting similar shaped jaw arranged above the stationary jaw, the apex portion of the upper triangular jaw being divided, parallel spaced leg members extending from the free ends of the arms of the triangular shaped upper jaw and being pivotally connected to and engaging the respective sides of the aforesaid member adjacent the stationary jaw, a trigger pivotally connected adjacent its upper end to the elongated member forwardly of the hand grip, an elongated link pivotally connected at its rear end to the uper end of the pivoted trigger, the forward end of the link being pivotally connected to the last-mentioned jaw between the apex portions-of the arms of said triangular shaped aw. J In testimony whereof I affix my signature.

AUGUST G. IOERGER.
