HORSESHOE-CALKING MACHINE.

Application filed May 10, 1915.

T 0 all whom it may concern:

Be it known that we, ALBERT D. CART- WRIGHT and ALFRED BAER, citizens of the United States, and residents of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Horsesh'oe-Callcing Machine; and we do hereby 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 characters of reference marked thereon, which form a part of this specification.

This invention relates particularly to horse-shoe calking machines.

The object of our invention is the pr vision of a simple, efficient and improved machine of the character described, which is operable to perform several distinct operations on a horse-shoe in the course of manufacture, namely, turning over the heel calks, upsetting and shaping the same to adapt them for summer or winter use, welding the toe calk on the shoe and then shaping it, and also forming a shoe with the block form of heel calks, thereby materially simplifying the calking of horse-shoes and enhancing the practicability and commercial valve of machines of this class.

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a machine embodyingthe invention and illustrating the heel calk turning operation. Fig. 2 is a front elevation of the machine, with parts broken away, and with a horse-shoe in heel calk upsetting position. Fig. 3 is a central vertical section of the upper portion of the machine with the parts in heel calk upsetting position. F ifgs. 4 and 5 are enlarged sectional details 0 a portion of the machine illustrating the heel calk turning-over means Specification of Letters Patent.

which is used when forming heel calk, the calk shaping dies being removed. Fig. 6 is a similar view with toe calk shaping dies in position and acting on a horse-shoe, and with the welding and block heel calk forming die removed. F ig. 7 1s a view similar to Fig. 6 with the block heel calk shaping die in position and act ing on a horse-shoe. Fig. 8 is a similar view with toe calk crimping dies in position and acting on a horse-shoe, and with the welding die in position and acting on the toe calk of a horse-shoe to weld it to the shoe body, and Fig. 9 is a bottom view of a horse-shoe having block heel calks and a crimped toe calk.

Referring to the drawings, 1 designates a machine frame or standard, which is provided at its front side with a forwardly, upwardly and rearwardly extending yoke or arm 2, and at the rear of said arm the frame is provided with the upwardly eX- tending transversely spaced arms 3 and 4 which cooperate to form a fork as shown.

The arm or yoke 2 is provided in a vertical plane in its free end with an opening through which a stem 5 projects, said stem carrying at its lower end an anvil-die {T- and at its upper a head 7. A coiled compression spring 8 is interposed between the arm 2 and head 7 to yieldingly hold the die 6 seated against the under or inner side of the arm. The die 6 may be turned relative to the arm 2 to bring different of its lower edges into operative position, as hereinafter more fully described. The die 6 when seated against the arm 2 is prevented from turning relative thereto by coaction at one of its edges with a shoulder 9 on the arm. .In order to turn the die it is necessary to force the stem 5 and die inwarda sufiicient distance to escape or free the shoulder 9.

Pivoted within the arm 2, as at 10, is a substantially L-shaped pressure block 11, which extends rearward from said pivot and then upward through the registering top portion of the frame 1 and in position, when raised, to bear upward at its free end against the anvil-die 6, or against an interposed horsea block type of .shoe or other work piece a to clamp it firmly to the die 6, as shown in Fig. 1. A foottreadle 12 is pivoted, as at 13, in the base portion of the frame 1 and has connection at the rear of its pivot through a connecting rod 14 with the pressure block 11 at the angle portion thereof, whereby a lowering of the outer end of the treadle from the dotted line position to the full line position in Fig. 1 effects a raising of the pressure block 11 into operative work clamping relation to the die 6.

A shaft 15 extends between and is journaled at its ends in the upper ends of the fork arms 3, 1, and is provided at one end with a crank-handle 16 to facilitate a hand turning of the shaft. :Fixedly carried by the shaft 15 between the fork arms is a heavy fly-wheel 17 that is provided, in the present instance, 011 the side thereof adjacent to the fork arm 3, with an eccentric or cam shoulder 18, which extends entirely around the axis, and is for the purpose hereinafter described.

A frame part or head 19 is pivoted, as at 20, within a vertically disposed recess or groove 21 in the outer side of the fork arm 3 and is secured at its lower end in adjusted relation to the fork arm by a screw 22, which passes through an aperture in the lower end of the frame part or head and threads into the base portion of the frame fork, as shown in Fig. 3. The frame part or head 19 has two arms or ledges 23 and 2 1 projecting outward in spaced superimposed relation therefrom, and, in the present instance, at opposite sides of the pivot 20. The arm or ledge 23 has a seat on the top of its outer end portion for a heel calk upsetting die 25 and has an opening extending vertically therethrough from said seat for the die stem 26 to project through. The lower end of the die stem 26 is preferably provided with a removable head 27, which permits the die and stem to have limited vertical movements relative to the arm 23 and facilitates a turn ing thereof. The inner edge of the upsetting die 25 coacts with a shoulder on the arm 23 to prevent a turning of the die when seated in operative position on the arm. The die 25 has calk upsetting recesses 28 of different depths in different top edges thereof, any one of which may be placed in operative position by a turning of the die.

An operating lever 29 is fulcrumed to the upper end of the frame part or head 19 above the arm or ledge 24: thereof, as at 30, in transverse relation to the plane of rotation of the wheel 17 and has its inner end of sufficient length to project over the cam shoulder 18 of the wheel and carrying a roller 31 for riding on said shoulder at the top side thereof. The eccentric orcam form of the shoulder 18 causes the lever 29 to have predetermined oscillating movements when the wheel 17 is rotated. Pivotally depending from the lever 29, at a point without its fulcrum 30, is an upsetting plunger 32, Which is provided at its lower end over the inner recessed edge of the up-setting die 25 with a recess 33, which, when the plunger is lowered, is intended to fit over the inner heel edge of a horse-shoe a and force the calk Z) of the horse-shoe into the registering recess 28 of the die 25 to effect a desired upsetting of a calk. A toggle link 34 is interposed between the front or outer side of the frame part or head 19 and the free end portion of the upsetting plunger 32, being pivotally connected to each as shown. WVhen the plunger is in raised position the link 34: stands at an upward incline from the frame part or head 19, as shown in Fig. 2, and

when the plunger is lowered the link causes a limited outward swinging of the free end of the plunger to force it outward into up setting relation with the outer side of a heel calk, which is being acted on. evident that the plunger 32 has a compound downward and outward pressure on a heel calk to cooperate with the die 25 to effect a desired upsetting thereof.

It is thus The upper frame or ledge 21 of the frame l head 19 is of forked form andhas the inner sides of its fork arms provided with registering longitudinally extending grooves or recesses 35. A die block 36 is removably mounted within the forkedend of the arm 21, being provided for such purpose with ribs, which slidingly engage within the grooves 35 of the arm. The inward movement of the die block 36 within the forked end of the arm 2% is limited by the length of the grooves 35 and also by shoulders 37 within the forked portion of the arm. The die block 36 is disposed below the extended jaw end 29' of the lever 29 and is intended to cooperate with said lever both to partially form a block type of heel calk c, as shown in Figs. 4: and 5, and to force a toe calk (Z of a horse-shoe into welding relation with the shoe, as shown in Fig. 8. To facilitate the use of the die 36 for calk turning purposes the die is provided at one end thereof with a spur 36', which, when the die is in operative position for turning a block heel calk 0, extends outward and upward from the outer end of the die block and beyond the end of junction with the jaw 29 when a broad or summer type of toe calk is to be welded to a jaw. The opposite side of the die block 36 is provided with different V-notches or recesses 39 to adapt it, when reversed from the positions shown'in Figs. 4 and '5 and disposed in the-position shown -in Fig.'--8,.'to"be used in connection with the welding of sharpened or winter toe calks to a shoe, as illustrated in Fig. 8. hen welding a toe ca-lk to a shoe the call: is placed in engagement with the proper surface of the die block 36 and the shoe is disposed over the calk in position for the jaw 29 of the lever and the die block 36 to force the calk and shoe into welding relation.

The frame part or head 19 has its upper end extended a short distance above the le- .ver pivot 29 and provided in its top with a recess 40 for removably receiving a calk shaping die 41 of desired form. The lever 29 at the rear of the upper extended end por tion of the frame head 19 is provided with a shoulder in opposition to the recessed portion of the head and this shoulder is provided with a recess or socket 42 for removably receiving the shank of a calk shaping die 43. If it is desired to shape aheel calk of block form, as shown in Fig. 7, the proper dies 41 and 43 for such purpose are secured in position and the wheel 17 turned to effect an oscillating of the lever 29, which forces the die 43 toward the die 41 and effects the desired shaping of the calk. The dies 41 and 43 may be changed to suit the work to be performed, as different dies are used in connection with the shaping of different forms of heel calks and different forms of nose calks, as is apparent by reference to Figs. 3, 6, and 8. The upper end of the frame head 19 is provided with a horizontally-disposed extension or arm 44 for supporting the outer end portion of a shoe when a calk thereof is being shaped by a set of dies 41, 4.3,

In orderto adapt the machine to be used for the severing or cutting off of metal articles, the lever 29 is provided on one side of its outer end portion with a shearing die or plate 45 (Figs. 1 and 2), which, upon a downward rocking of the outer end of the le ver, has shearing coaction with a stationary shearing die or plate 46 on a side of the frame head arm 24.

Thefly -wheel 17 is provided on its periphery with a radially projecting boss47, which is provided on the forward side thereof, relative to the direction of rotation of the wheel, with an inclined wiper plate or surface 48, which is disposed to have wiping coaction with the heel end of a shoe when' clamped by, the anvil-die 6 and pressureblock 11 and extended a short distance therefrom toward the wheel, as shown by dotted lines in Fig. 1. The coaction of the wiper surface of the boss 37 with the heel end of a horse-shoe, when clamped 'as shown in Fig. 1, causes an upward bending of the heel end portion at its outer end with a roller 49,

whichprojectsslightly beyond the outer end of th'eincline'd wiper surface 48 and coacts with the registering heel end of the horseshoe to complete the upward bending there of, as is apparent by reference to Fig. 1.

In the use of our improved machine the operation of the same in connection with the forming of calks on horse-shoes is as follows: In forming the heel call; the heel end the arrow in Fig. 1, thereby causing the wiper surface 48 and roller 49 of the wheel boss to have wiping coaction with the extended end of the horse-shoe and to bend it in upright position or at right angles to the body of the horse-shoe, as indicated in Fig. 1. This having been done the calk is placed over the upsetting die 25 in the manner shown in Fig. 2, and the wheel 17 then given another turn to rock the lever 29 and force the upsetting plunger 32 into engagement with the heel end of the horse-shoe to cooperate with the die 25 to impart the desired upsetting action to the calk. The heel calk is then placed between the desired set of shaping dies 41 and 43 and the wheel 17 turned to rock the lever 29 and cause a relative movement of the shaping dies to give the final shape to the calk to suit the same for winter or summer use, as desired. These successive operations may be performed in such rapid order that a single heating will suflice for all operations. It will be understood that the heel calks Z) may be made of any desired depth by extending the end of the shoe a greater or less distance beyond the edges of the die 6 and pressure block 11. When it is desired to make the calk of block form the initially bent-up portion of the shoe is made of sufficient length for such purpose and the heel end of the shoe is then placed between the clamping aw 29 of the lever and the turning spur 36 of the die block 36, said die block being first positioned with the spur 37 thereof projecting upward from its outer end, as shown in Figs. 4 and 5. WVhen the lever is operated by-a turning of the wheel 17 the bent-up calk portion of the shoe is doubled over on the heel end of the shoe, as shown 111 Fig. This calk 1s then given the desired shape by compression between the desired set of dies 41, 43, as shown in Fig. 7. In affixing a toe calk (Z to a shoe the stem of the calk, after being heated, is inverted or partially inserted into the aperture provided therefor in the shoe, and the ingof the wheel 17 to effect a forcing together of the calk and shoe and a consequent close welding of the same. If a summer type of calk is used the die-block 36 is preferably positioned with the flat surface 38 thereof disposed at its top side, and if the calk is of the winter or sharp type the V- notched surface of the die block is placed uppermost, as will be readily understood from the drawings. The welding operation having been effected the toe calk is placed between the desired set of shaping dies 41, 43 and the lever operated to impart the final shape to the calk. Should wear occur be tween the parts of the lever and wheel, which cooperate to impart rocking movements to the lever when the wheel is turned, such wear may be compensated for by an adjustment of the frame part or head 19 relative to the wheel carrying fork of the frame. This adjustment may be accomplished by inserting a block or shim piece of desired thickness between the lower end of the head 19 and the base of the fork arm groove 21, the screw 22 being loosened and then tightenedagain for such purpose.

It will be understood that we have provided a simple and efficient machine which is adapted to perform all the necessary operations in forming or affixing calks to a horse-shoe and then imparting the desired shape thereto. It is also apparent that the lever 29 has a manifold purpose in that it is utilized in conjunction with the plunger 32 and die 25 to upset-a heel calk; in conjunction with the die block 36 to double over a heel calk in block form, and to weld a toe calk of either summer or winter form to the shoe; and in conjunction with the upper end of the frame head 19 and the dies 41 and 43 to impart the final shaping action to either the heel or toe calks. In addition to the above the lever 29 is also operable to impart shearing movements to the shearing die 45 with respect to the shearing die 46.

We wish it understood that our invention is not limited to any specific construction, arrangement or form of the parts as it is capable of numerous modifications without departing from the spirit'of the claims.
