MACHINE FOR WELDING CALKS TO HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 440,372, dated November 11, 1890.

Application filed September 1, 1390. Serial N0.363,703. (N0 model.)

To all whom it may concern.-

Beit known that I, CHARLES E. SOHROEDER, a citizen of the United States, residing at Crown Point, in the county of Lake and State of Indiana, have invented a certain new and useful Improvement in Machines for W'elding Oalks to Horseshoes, of which the following is a specifiation.

My invention relates to improvements in machines for welding calks to horseshoes and analogous purposes; and it consists in certain peculiarities of the construction and novel arrangement of the various parts thereof, as will be hereinafter more fully set forth, and specifically claimed.

The objects of my invention are to afford a machine for the above-named purpose which shall be inexpensive, simple in construction and operation, strong and durable, and more effective and rapid in its work than the ordinary manner of welding.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1 is aplan view of my machine. Fig. 2 is a view in side elevation. Fig. 3 is a vertical sectional View taken on line a: 00 of Fig. 2 and looking in the direction indicated by the arrows. Fig. 4 is a longitudinal sectional view showing the interior mechanism and the shoein place to be operated on. Figs. 5, 6, and 7 are detail views of the operating-lever and its fulcrum. Fig. 8 is a rear end view of the machine. Fig. 9 is a perspective view of one of the die-plates, and Fig. 10 is a view of one of the calk-pieces.

Similar letters refer to corresponding parts throughout the different views of the drawlngs.

A represents the main frame of my machine, which is made of suitable size and material, and, as shown in Fig. 2 of the drawings, may be bolted to a proper supporting device by means of bolts passed through the openings a thereof. In constructing this frame I preferably make it of two plates A A which are similar in size and every respect, except that the plate A is provided with bearings for certain levers, which will be presently explained. Between these two plates, and at the upper portion of the front end thereof, is firmly secured by meansof screw-bolts a, or otherwise a block or anvil B of solid metal or material, which is provided near its upper inner portion with a projection a which extends horizontally across the anvil B and is adapted to engage with a suitable groove in the die or dies 0, as will be more definitely explained.

The plates A A are cut away near their upper central portion, as at b, to readily admit the insertion and the extraction of the shoe D and die 0, as is clearly seen by reference to Figs. 2 and 4 of the drawings.

The inner surfaces of the upper rear portion of the plates A A are provided with in wardly-projecting pieces 0 c, which form a track or guideway for the plunger E, which is made of rectangular shape and formed at its front end solid, with a flat face to be presented to the side of the die. The rear end of this plunger is bifurcated, as seen in Fig. 4, which permits of it being easily adjusted to or from the die to accommodate shoes of different thicknesses. In the bottom of the solid portion of the plunger and near the front end of the fork is formed a recess, (not shown in the drawings,) into which the free end of the spring F is inserted, the said spring being firmly secured at its lower end to a bolt 0, which assists in securing the plates A A together, and the spring serves to retract the plunger after it has been thrown forward by the operating-lever G, which is formed at its lower end with an eccentric d, which is fulcrumed on an eccentric-pin H, which pin has its bearings in the upper rear portion of the plates A A as shown in the drawings.

At a suitable point on the lever G is adj ustably secured, by means of a set-screw e or otherwise, a weight I, which accelerates the fall of the lever, and thereby adds force to the blow of the plunger, as will be readily understood.

To the outside of the plate A a springactuated lever K is fulcrumed, as at e, and has on its upper end a pin 6 loosely secured thereto, which pin passes through a hole in the plate A and into a recess a of the eccentric on the lever G, thus holding the lever in the position shown in Figs. 2 and 4. When it is desired to release the lever G, the lower end of the lever K is pressed toward the plate, which operation withdraws the pin (2 from its socket, and thus allows the lever to descend. When the lever G is raised to the position shown in Fig. 2, the spring m, which is secured at one end to the plate A and has its free end resting against the inner side of the lever K, forces the pin 6 back into the socket, as will be readily understood. The eccentric H hasits bearings in the side pieces A A of the main frame and projects slightly through the piece A to which projecting end a handle or lever L is rigidly secured by means of a set-screw or otherwise to operate the eccentric when it is desired. It will be understood that the eccentric H serves the twofold purpose of an axis or journal for the lever G and to adjust the plunger E to accommodate shoes of different thicknesses, for by turning the eccentric H slightly or half-way round, as shown by dotted lines in Fig. 5, as at n, the plunger E will be forced correspondingly forward, as indicated by the dotted lines in the same figure. In Fig. 9 I have shown a detail view of a die-plate having a series of recesses 0 of various sizes and forms, into which the calk-piece is forced and formed. As shown in the drawings, I form these recesses with an inward bevel, which shape corresponds to the beveled or sharpened form of the calk when it is being welded to the shoe. It will therefore be seen and understood that I sharpen the calk at the same time and by the same operation that I employ in welding it to the shoe. It is sometimes desired to form the shoe with a projection r on the top of the toe of the shoe op-' posite the toe-calk, and in order to do this I provide the upper portion of the front end of the plunger E with a depression 19 of suitable size and form. When it is not desired to form the shoe as above described, the depression 19 may be plugged by a suitable piece secured therein.

To form the heel-calks on the shoe, the shoe is heated to the proper degree and placed and held against the plate 0 by the plunger, when the ends may be bent over the die-plate by a stroke or two of a hammer.

Fig. 10 represents an ordinary steel calk as it appears before being attached to the shoe.

The operation of my device is simple, and as follows: The die-plate is placed in the frame, as shown in the drawings, and held in place by the projection a in the groove of the plate. The calk is attached to the shoe by driving the prong thereof into the shoe when both are heated to the proper degree. The calk is now placed in one of the recesses 0 and the lever K pressed to the frame, which liberates the lever G, which descends and throws the plunger forward with great force, thus welding and shaping the calk, as has been before explained.

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

1 In a machine for welding calks to horse shoes, the combination of the main frame A, having the anvil B, provided with the projection a to secure the die C, with the die having a number of recesses 0, the plunger E, the lever G, having the adjustable weight I, and eccentric d,'journaled on the eccentric H, all constructed, arranged, and operating substantially as shown and described, and for the purpose set forth.

2. In a machine for welding calks to horseshoes, the combination of the frame A, having the anvil B, having means for supporting and retaining the die 0, and a track 0 for the plunger E, with the plunger having one end bifurcated and the other end solid, the lever G, having the adjustable weight I, eccentric d, having the recess 6 and fulcrumed on the eccentric H, the eccentric H, having the handle L, and the lever K, fulcrumed to the plate A and having the pin 6 to engage the eccentric d, all constructed, arranged, and operating substantially as shown and described, and for the purpose set forth.

3. In a machine for welding calks to horse-- shoes, the combination of the main frame A, having the anvil B, having means for supporting and securing the die 0, a track for the plunger E, with the plunger having one end bifurcated and the other solid and provided with the recess 10 and spring F, the lever G, having the adjustable weight I, the eccentric d, having the recess 6 and fulcrumed on the eccentric H, the eccentric H, having the handle L, the spring-actuated lever K, having the pin e and the die-plate 0, having a number of inwardly-beveled recesses, sub-. stantially as set forth.

In Witness whereof I have hereunto set my hand and affixed my seal this 27th day of August, 1890.

CHARLES E. SCHROEDER.
