STOCK-RINGER.

Specification of Letters Patent.

Patented Apr. 9, 1912,

To all whom tt may concern:

Be it known that we, WILLIAM H. LEAVER and CHARLES H. SMITH, citizens of the United States, residing in Chicago, county of Cook, and State of Illinois, have jointly invented certain new and useful Improvements in Stock-Ringers, of which the lfollowing is a specification.

This invent-ion relates to stock ringers and more particularly to a device for inserting rings through the tips of hogs noses to prevent rooting.

The invention has for its object the provision of a spring actuated device which will act almost instantaneously to bend and secure the ring through the tip of the animals nose while it is feeding, thus eliminating the necessity of catching the animal and by main force inserting the ring through his nose with a pair of manually operated pliers as has been the custom heretofore.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawing: Figure 1 is a central longitudinal sectionalk view of the device with the parts in their actuated osition; Fig.v 2 is a fragmentary detail section of the trigger mechanism of the device in its cocked position; Fig. 3 is a view in side elevation of the rear or butt end of the device, and Fig. 4 is a sectional view' of the front end of the device as it appears before the bending of the ring.

As shown in the drawings, the device has the general form of a pistol, it being provided with a barrel 1, a grip or butt 2, and a trigger guard '3 located adjacent to the said grip or butt. The barrel 1 which is formed of sheet metal and is preferably o f cylindrical shape is provided at its forward end, or that end remote from the butt, with a stationary jaw 4 which is formed integral with the said barrel and which embraces a bottom wall and two vertical side walls 5. Between the vertical side walls 5 of the lower jaw is mounted the upper jaw 7 which is pivotally securedthereto by means of a transverselyv4 extending pivot pin 8. The forward end of the jaw 7 is adapted to engage the curved portion of the ring as is shown in Fig. 4, and the said jaw is adapted to be actuated to bend the ring into the form shown in Fig. 1.

- As a means for moving the upper jaw 7 to bend the ring, there is provided a longitudinally extending rod 11 which is operatively connected with said upper jaw. The means here shown for translating the longitudinal movement of the rod into vertically swinging motion of the upper jaw comprises a pair of links 9 which are pivotally connected at their upper ends to a rearwardly extending portion of the upper aw 7 and at their lower ends to a cross-head 6 formed upon the forward end of the rod 11. The said rod `11 is preferably stamped from sheet metal and is provided near its forward end with lateral projections 12, 12. This rod is adapted to be forcibly moved forward by means of a helical spring 13 which surrounds the said rod and bears against the kwhich is hinged to the stock or butt 2 by means of a pivot 15. This lever is so shaped as to lie flat along the top of the barrel, and is preferably made of pressed metal and curved and ribbed to give it the necessary strength. The said lever is connected with -the spring 13'by' means of a link 17. This link is connected at its rear end to the downwardly projecting portion of the lever 14 by means of a transversely extending pivot 16 and is provided at its forward end with a notch or recess 18 which engages a loop 19 formed upon the rear end of the spring' 13. The pivotal point at the rear end of the link 17 vis arranged in such relation to the points 15 and 19 that when the lever is in its normal position the back pressure of the spring 13 upon the forward end of the link 17 tends to rotate the lever about its pivot 15 in a direction to hold the lever tightly pressed against the top of the barrel. In placing the spring under tension the lever 14 is rotated about its pivot 15 through an angle of substant-ially one hundred and eighty degrees, by which movement the pivot 16 is also caused to rotate through one hundred and eighty degrees about the pivot 15 and to draw with it the link 17, and the spring 13. The last coil of the spring 13 engages a downwardly Y lower jaws of the device.

projecting lug 20 on the rod 11 and draws said rod andt-he cross-head to their most rearward positions in the barrel. In this latter position the lug 20 engages the notch 21 in a pivoted detent 22, movingl that detent upon its pivot 23 until the extension 24 thereof rests upon the top 25 of the trigger 26. This trigger is pivoted at 27 and is normally held in its forward position by means f of the spring 28, which serves also to hold the detent 22 in its released position. While the lever 14 is in its extended position, the upper jaw 7 is in the position shown in Fig. 4, and the ring is then inserted, the jaws being opened suiiiciently to receive the ring. The lever 14 is then forced forward to the osition illustrated in the drawing. In so oing the rear end of the coil spring 13 is forced forward by means of the link 17 and the loop 19, but the projection 2O on the rod 11 is retained by the notch 21 in the detent 22 and the forward end of the spring is thus retained while the rearward end is moved forward through the distance of substantially one inch. The notch 21 is made large enough that the projection 2O will have some slight play therein so that the rod 11 moves forward slightly as the return movement of the lever is started and the upper jaw 7 is thus pressed tightly upon the ring holding it firmly in position between the upper and Then now the i point of the ring is placed in the position to be inserted and the trigger 26 is pulled the extension 24 of detent 22 slips off of the top 25 of the trigger and rotates to it-s posi- Y tion illustrated in Fig. 1, allowing the key 20 to slip out of the notch 21 and permitting the cross-head 6 to move forward to close the ring. It will be seen that in the movement of the cross-head from a position to the rear of the pivotI which attaches the link 9 to the upper jaw to a position in front of that pivot, the upper jaw will be given a compound movement, that is, the ring will be closed and the upper jaw will again be moved in its reverse direction to release the ring. The arrangement of parts for moving the jaw accomplishes an equalization of pressure upon the ring, that is, while the spring is under its greatest compression, the greatest amount of movement is transi mitted to the upper jaw for the least amount of movement of the spring, and as the spring approaches the final end of its movement and its pressure diminishes, the toggle ar- A rangement approaches the vertical position and a less movement is transmitted to the parting from the spirit or scope of our invention.k
