IMPROVEMENT IN HORSE-SHOE MACHINE.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, CHARLES H. PnnKINs and RICHARD W. CoMs'rocK, both of the city and county of Providence, in the State of Rhode Island, have invented certain new and useful improvements in Machines for Making Horse-Shoes; and we do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure 1 is a side elevation with the side of the frame removed.

Figure 2 is a. top view.

The machine herein described is intended to embody in its mode of operation the combined advantages which result from fashioning a horse-shoe by both the hammering and the rolling-processes, which have heretofore been separately employed.

In the accompanying drawings, A represents a rectangular bed or frame, of sufficient height and width to allow space beneath the table for the machinery for giving motion to the sliding anvil hereinafter described. Instead of a tilting or other form of hammer commonly employed, we make use of one or more rotary hammers, B B, which are in the form of lcylindricall rollers, made of steel, and fitted to turn upon axles mounted in a revolving frame, C C, radiating from the shaft D. A rapid motion isto be given to such shaft by a beltror other means.l The blank from which the shoe is to be made before it is presented to the machine has, as is new customary, been bent into the general form of a shoe by other machinery, as, for example7 such as.is described in an application made by us of an even date herewith for Letters Patent for a-machine for bending the blanks of horse-shoes. Instead of a stationary anvil or die for holding the blank while it is being hammered, we employ a movable one, so arranged with reference to the revolving hammers B that it shall .travel continuously underneath the faces of the hammers until every part of the surface of the blank has been hammered, but at a rate of speed quite slow in comparison with the speed of revolution of the hammers. This movable anvil is shown at E. It is provided with a raised die-block, a, whoseV outline is in the form of thereverse of theshape to be given to the under side of the shoe, and is mounted upon a bed, F, which is arranged between suitable guides, to have a reciprocating movement given to it'. This movement, in this instance, is effected by means of the long arm Gr of the bell-crank lever G H, whose fulcrum is the transverse axle I), and is made-to vibrate in consequence of the action of the revolving cam I, madc fast to the axle C of the toothed wheel J, (whose motion is derived from the shaft D through the belt cl and pinion JQ) impinging against the surface of the short arm II of the bell-crank lever. After thc cam I has in the course of its revolution moved away from the surface of the, arm H, the bed F and the bell-crank lever, whose longer arm bears near its end against the rear of such bed, is drawn backward by a weight, lc, attached by a cord, c, to the bed, orby other convenient means. The sliding bed described is furnished with a pair of tongs, L, pivoted to the bed at f, and kept open by a spring, g. The jaws of thc tongs embrace thc rear portion of the die-block a, and are intended to gripe by the heels a shoe which has been placed upon the anvil. A hinged double lever, M M, united by the cross-bar M,-will, when raised, as shown in red outline, fig. 1, allow the spring g to open the tongs, but when depressed, as shown in black outline in the same figure, will, by means of inclined planes atlixcd to the inner sides of the levers, press against the edges of the handles ofthe tongs and cause the jaws of the same to close.

From the foregoing description it will be understood that if a blank be placed upon the anvil in front of and embracing the die-block a, and the machine be put in operation so soon as the cross-bar M of the levers M M has, by the forward movement of the bed F, descended the inclined plane t, the operator can by pressure upon such cross-bar cause the tongs 'to gripe the blankby the pressure of itsjaws against the outer edge of the heels. The continual movement of the bed will carry the blank underneath the revolving hammers, which will in rapid succession strike the surface of the shoe at every point which is tangential to the circumference of the hammers and effect what is technically termed the i plating of the shoe. After the blank has passed beyond the action of the hammers, the levers M M can be raised so as to release the gripe of the tongs, when the finished shoe can be removed by any suitable means.

It will be observed that accompanying the percussive action of the hammers to render dense and compact the particles of the metal, there is also a drawing action, the effect of which is made very apparent upon the toe ofthe shoe Where the line of motion of the hammers is across the grain of the metal, and by means of which the shoe is made broad at the point where the greates breadth is required'.

What we claim as our invention, 'and desire to secure by Letters Patent, isA

The combination, in a machine for making horse-shoes, of the following instrumentalities: A rotary hammer, B, a. sliding anvil, E, or equivalent apparatus for supporting the shoe-b/lank, and the griping-tongs L, arranged relatively to each other, and operating substantially as described for tbe purposes specified.
