GILES C. CARPENTER, OF FILLMORE, NEW YORK.

FARRIERS ANVIL.

' srEc'IrIcA'rroN forming part of Letters Patent No. 437,355, dated 'september so, 1890.

Application tiled January 27, 1890. Serial No. 338,218. (No model.)

To aZZ whom it `may concern:

. Beit known that I, GILEs C. CARPENTER, a citizen of the United States, residing at Fillmore, in the county of Allegany and State of New York, have invented a new and useful Improvement in Farriers Anvils, of which the following is a specification.

This invention relates to that class of anvils which are provided with a vise for holding a horseshoe in place during the operations of forming and sharpening the calks.

The object of my invention is to produce an inexpensive vise attachment of simple construction, which is readily applied to the anvil, and which may be moved out of the way below the working-face of the anvil when not required for use, so as to permit other work to be placed upon the anvil and conveniently manipulated.

In the accompanying drawings, Figure l is a sectional end elevation of an anvil provided with my improved vise attachment, showing the vise in an inoperative position below the working-face of the anvil. Fig. 2 is a sectional end elevation of the anvil and vise, showing the latter in its operative position with a horseshoe clamped therein; Fig. 3 is a horizontal section in line oc, Fig. 1. Fig. 4 is a similar View in line y (y, Fig. l.

Like letters of reference refer to like parts in the several figures.

A represents the anvil, and B the block upon which the anvil rests.

C C represent two rock-levers pivoted between their ends to opposite sides of the ani vil. These rock-levers are connected at their rear ends by a cross-bar c and in front of the anvil by a tie-bolt c. rlhe levers C are rocked or oscillated upon their pivots by a treadle D, pivoted at its rear end to one side of the anvil-block B and connected by a rod d with the front arm of the rock-lever C above the same. The ends of the cross-bar c are pret'- erably seated in openings formed in the rear ends of the rock-levers C C, which permit the` rock-levers to be adjusted toward and from each other for different sizes of anvils.

. E represents the outer jaw of the vise, which is secured to the cross-bar c, so that the jaw is raised and lowered with thercross-bar and caused to approach and recede from the rear side of the anvil. The jaw E is connected with the cross-bar c by means of a shankl or lever E', the jaw being provided with a socket e, which its over the upper en'd of the lever E', and is secured thereto by a set-screw c', whereby the jaw is made adjustable on the shank or lever E.

F represents a vertically-movable inner jaw arranged adjacent to the rear side of the anvil opposite the outer jaw E, and which is pivoted to the bifurcated upper end of an upright bar f by a transverse bolt, so as to be capable of swinging toward and from the an vil. The lower portion of the bar f is pivotally connected with an arm g, which latter forms a downward extension of the shank E of the outer jaw E, by a link h, which permits the bar f and the jaw attached thereto to move vertically with reference to the outer jaw. The inner jaw F is provided at its upper end wit-h a forwardly-projecting lip or shoulder c', which is adapted to engage over the adjacent edge of the anvil when the vise is in an operative position, so as to support the jaw and its depending bar f upon the an' vil. The upper face of the jaw is inclined or beveled, as shown at i', to form a shapingseat for the calks of the horseshoe.

j is a spiral spring connecting the lower ends of the bar f andthe arm g, and which tends tohold the inner jaw and the upper end of the bar f against the side ot the anvil. 7c represents a rearwardly-projecting arm or link pivoted at one end to the armgof the outer jaw and at its other end to an upright supporting-bar 7c. The bar 7c is attached at its lower-end to the supporting-block B, preferably by a hinge, as shown. The inner end ot the arm 7c is bifurcated and pivoted to the arm g by the same bolt which connects the link h to said arm, as represented in Figs. l,l

2, and 4.

Zis a circular head formed at the inner end of the arm k and having a notch or recess l in its periphery. l

'm is a locking pawl or catch pivoted to the lowerportion of the depending-bar f of the inner jaw and provided on its rear side with a nose or projection m', which is adapted -to enter the notch of the head Z.

Y .fais a spiral Yspring attached at one end to ICQ the pawl mand at its other end tothe-arm of the outer jaw E, and which holds the pawl,

against the notched head Z. The lookin gpawl is provided aboveits nose m with an arm or extension m2, which projects into the path of the cross-bar c, connecting the two rock-levers C C, so that when said cross-bar is raised it rides over the extension of the pawl, thereby swinging the latter toward the anvil and disengaging its nose from the notch in the head Z.

When the vise is in its inoperative position, as represented inFig. 1, the jaws E F are open and stand below the working-face o f the anvil, and the nose of the locking-pawl is interlocked with the notched head of the arm' k. When the pawl m is engaged with the notched head of the arm 7c, the latter and the link h, which connects the bars f and ging the inner jaw and the arm g ot' the outer jaw, but not to the inner jaw itself. Upon firstl depressing the treadle the rock-levers are swung on their pivots and both jaws E F are raised; but, owing to the temporary rigidity of the connection between the inner jaw and the arm 7c, the inner jaw is caused to rise in advance of the outer jaw until its lip t' engages over the edge of the anvil and supports the jaw and its bar f upon the anvil. The continued downward movement of the treadle causes the cross-bar c to ride over the eXtension of the locking-pawl m and release the latter from the notched head Z of the arm k, thereby breaking the rigid connection between the depending bar f of the inner jaw land the arm Z and allowing the inner jaw to remain at rest, while the inward and upward movement of the outer jaw continues until it strikes the inner jaw or the horseshoe placed between the jaws. The inner jaw is thus raised to its highest position, in which its lip overlaps the edge of the anvil only during the first part of the stroke of the treadle, while the outer jaw is raised and moved toward the inner jaw during the entire downward stroke of the treadle. The horseshoe is clamped between the jaws of the vise with its calk resting upon the beveled upper face of the inner jaw in a well-known manner, the horseshoe being gripped so long as the foot is kept upon the depressed treadle. Upon releasing the treadle the weight of the outer jaw and connecting parts causes the jaw to drop from the inner jaw, which latter remains supported upon the anvil. Upon again depressing the treadle to clamp another shoe the inner jaw remains at rest and the outer jaw is closed against the shoe placed against the inner jaw.

Vhen the vise is not required for use, the inner jaw is pushed away from the anvil to disengage its lip from the edge of the anvil, when the jaw will drop below the workingface .of the anvil, where it is out of the way and does not interfere with the ordinary use of the anvil.

By myimproved mechanism the inner jaw of the vise is raised to its operative position and the outer jaw moved toward the same by a single depression of the treadle without requiring the inner jaw to be' placed in posi-v tion upon the anvil by hand, thereby bringing the viseV into service with. readiness and convenience when required.
