MACHINE FOR PUNCHING AND FORMING CALKS 0N HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 494,623, dated April 4, 1893.

Application filed October 20, 1892.

To all whom it may concern:

Be it known that I, WILLIAM NELSON BRIGKEY, a citizen of the United States, residing at Morrillton, in the countyof Conway and State of Arkansas, have invented certain new and useful Improvements in Machines for Punching and Forming Oalks on Horseshoes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My present invention relates to a novel machine or implement by which calks can be formed on horse shoes and the holes punched therein to receive the nails by which the shoe is fastened on the animals foot.

The object of my present improvement is, first, to provide simple and effective means whereby the calks can be quickly, easily and accurately formed on the horse shoe; second to quickly punch or force the nail-holes in the shoe and without requiring the shoe to be reheated after the calks have been formed and prior to the punching of the holes; thirdly to prevent the punch-die from becoming over heated by the provision of means which serves to cool the die each time it passes through the hot metal of the shoe; and finally to simplify cient and reliable in operation.

With these and other ends in View, the first part of my invention consists in the combination with a vertical upright or standard, of a pivoted clamp -bar which is arranged alongside of the standard and has a die or anhead or plate pivoted to the fixed standard and adapted to carry a die in a holder which operates to bend the metal of the shoe to form a calk thereon, and a lever fulcrumed to a fixed support and bearing against the pivoted clamp and anvil bar to hold the latter in position to clamp the work between itself and the fixed standard.

The second part of my invention consists in the novel means for punching the holes in the shoe and keeping the punch-die cool,

which means consists of a reciprocating die Serial No. 449,501- (No model.)

guided in a fixed guide on the frame, the lever, a link pivoted at its ends to the die and the lever, and a tank adapted to contain wafor or other liquid and arranged in the bed of the machine to receive the punch die after the same passes through the hot metal of the shoe, whereby the reciprocating die is immersed in water or liquid at each stroke thereof. And finally the invention consistsin the peculiar construction and arrangement of parts which will be hereinafter fully described and pointed out in the claims.

The invention is fully illustrated in the accompanying drawings, forming a part of this specification, and in which;

Figure 1 is a perspective View of my improved calk-bending and punching imple ment or machine. Fig. 2 is a vertical sectional View thereof. Fig. 3 is a detail onlarged view of a part of the calk-forming devices, more clearly showing the form thereof on an enlarged scale.

Like letters of reference denote corresponding parts in the several figures of the drawings, referring to which:- g

Adesignates the bed of my improved calkforming and punching machine especially adapted for use by blacksmiths and others in manipulating shoe-blanks to be fitted to the feet of horses and other animals. On this bed is erected the supporting frame B, and the Vertical standard or upright O, which parts are rigidly and firmly secured to the bed and connected together by the horizontal struts or bars 0, c, which also serve as the guides for the free end of the clamp and anvil bar D. This bar D is arranged in a vertical position alongside of and close to the fixed upright or standard 0, and the upper end of this anvil and clamp bar is fitted and guided between the horizontal bars 0 0 while the lower end of said vertical bar D is pivoted to the bedA of the machine. The upper free end of the vertical pivoted bar D is adapted to bear or impinge against the front face of the vertical fixed standard 0, in order to hold or clamp the work between said b'ar D and the standard O; and normally this free end of the vertical pivoted bar is forced or thrown away from the fixed standard 0 by means of the spring E which is interposed between the bar and standard or otherwise connected in any ro ing plate to be turned at an angle to the length of the standard 0 or to be raised in line therewith. This bending pivoted plate F has its upper end provided with a handle 9 by which the plate can be readily turned, and on the lower central part of the plate is bolted or otherwise secured a die holder H, having its lower end provided with a notch or socket adapted to receive a die H of the proper size and shape to form the calk on a shoe. The

upper end of the vertical pivoted bar D is forked or recessed at 2' to enable the same to receive a corresponding die I, and between these dies 11, I, the metal is bent to form the calk on the shoe.

The dies may be of different sizes to adapt them to bend the calks on-shoes of different sizes, and any desired set of dies can be readily fitted in the sockets of the die holder and the end of the clamp and anvil bar D. On the upright fixed frame 13 of the machine is rigidly secured a vertical hollow guide J, and through the passage in this guide works a reciprocating punching die K, the lower end of which is adapted to pass through a perforation 7c in the bed A.

Immediately below the guide and the reciprocatin g punch die, I provide a liquid holding tank L which is suitably formed or secured in the bed A of the machine, and when the reciprocating punch passes through the perforation Is it is immersed directly in the liquid contained in the tank L so that the punch is cooled by the direct application of water thereto after each time it passes through the heated metal.

The reciprocating punch is operated by means of alever M which is fulcrumed at an intermediate point of its length to the frame B of the machine, as at m, and to this lever is pivotally connected one end of a link N which has its other end connected directly to the punch, as shown. This lever M is so arranged that its inner end is adapted to bear directly on the vertical pivoted bar D in or- 5 5 der to force the same inward to hold the work between its free end and the fixed standard 0; and this lever M thus serves a two-fold purpose, 2'. 6., to reciprocate the punch and to force the pivoted bar into position to hold the work between said bar and the standard.

plate, and the shoe-blank heated, the latter is fitted between the pivoted bar and the fixed standard so that one end thereof lies between the two dies. The lever M is now operated to force the end of the bar tightly against the shoe-blank, and the pivoted plate now turned at right angles to the standard so as to bend the end of the shoe blank and form the calk on the same. The lever is then operated to release the pivoted bar and blank, the latter turned so that its other end is between the dies, the lever again operated to clamp the pivoted bar on the blank, and finallythe pivoted die-plate is turned to form the other calk. The shoe-blank is now removed and placed in position beneath the punch, and the latter is operated by means of the lever so as to punch the holes in the shoe-blank to receive the nails. At each operation of the punch, it enters the water in the tank and is thus kept in a cool condition.

By means of this machine or implement the shoe-blank can have its calks formed thereon and the holes punched therein without reheating the blank,which is a very great advantage as itenables the workman to quickly finish the shoe.

The device is simple and durable in construction, reliable and effective in service, and cheap of manufacture.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
