DIES FOR FORMIHNG HORSESHOES.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed January 30, 1912. Serial No. 674,351.

To all 'whom t may concern Be it known that I, GEORGE KURSCHUS, a citizen of the United States of America, residing at Hastings, in the county of Barry and State of Michigan, have invented certain new and useful Improvements in Dies for Forming Horseshoes; and I 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.

My invention relates to improvements in dies for forming horse shoes and more particularlyv to such dies for welding on toe calks and finishing the shoe and its object is to provide automatic means for severing` and welding the toe calks; for shaping the rear portions of the shoe and forming the nail creases or grooves and in various features of construction and arrangement as hereinafter more fully described and particularly pointed out in the claims reference being had to the accompanying drawings, in which Figure 1 is a plan view of the bed plate and lower dies; Fig. 2 a vertical section of the device on the line 2-2 of Fig. 1; Fig. 3 a vertical section on the line 3-3 of Fig. 1; Fig. 4 the same as Fig. 3 with the movable dies in lowered position; Fig. 5 a vertical section on the line 5-5 of Fig. 1 with the movable dies in raised position; Fig. 6 the same with the movable dies in lowered position; Fig. 7 a plan view of the horse shoe blank ready to be operated upon by the machine; Fig. 8 a vertical section on the line 8-8 of Fig. 7 g Fig. 9 a plan view of the finished shoe; Fig. 10 a vertical section of the same on the line 10-10 of Fig. 9; and Fig. 11 the same on the line 11-11 of Fig. 9.

Like numbers refer to like parts in all of the figures.

1 represents a suitable bed plate to be attached to any suitable punch press.

2 an anvil plate inserted in the bed plate to support the blank where the toe calk is to be welded thereto.

3 are swaging dies having converging walls at each side of the heel portions of the shoe to swage the same horizontally when forced downward between the punches carried with the movable die.

4 is a cleat or holder attached to the anvil plate to engage the concave side of the toe of the shoe and overlap the same to locate tand hold the shoe in proper position upon the anvil plate.

5 is a reciprocating slide movable on the bed plate 1 in ways 6. This slide has an opening 7 with an inclined wall at one end engaged by a wedge 22 vertically movable in the opening to move the slide toward the shoe and in proper position to bring the cutting end 8 of said slide to act as one member of a shear to sever a portion from the end of a bar of steel 9 to form the toe calk. This slide is provided with a longitudinal groove to receive the said bar 9 and properly guide the same to place with its end properly located over the toe of the shoe'.

10 is a stop to properly locate the bar endwise which stop is pivoted at 11 to swing out of the way when removing the shoe after it has been operated upon. This stop is normally held in operative position by a spring 12 and a pin 13. The spring yields and permits the stop 10 to swing when the shoe is to be removed.

l14: is a contractile spring to move the slide 5 back out of the way of the shoe and 15 an adjustable screw which serves as a stop to limit the backward movement of the slide.

16 is a head to carry the upper die, the wedge andmthe punches provided with a suitable shank 17 to attach the same to the plunger of a punch press (not shown). Attached to this head are two punches 18 adapted to enter between the dies 3 and force the shoe downward therebetween to swage the same and on these punches are ribs or projections 19 which serve to form the nail creases in the shoe thus swaging the shoe laterally at the heel to make it thicker vertically and thinner horizontally as at 26a and forming the nail creases 3() at the same time. This head 16 yalso carries a die :for severing and welding the toe calk having a recess 2O formed therein to shape the said toe calk and a shoulder 21 which moves downward past the toe of the shoe opposite the holder 4 and thus forms the front of the calk and also passes downward opposite the edge of the anvil plate 2 and thus forms a fin 29 on the front of the shoe while simul receives the lower end of this die and also permits the escape of any surplus metal carried away by the same as it descends. The side angle of this diealso co-acts with the cutting end 8 of the slide 5 to shear the bar 26 and sever the necessary metal from the same to form the toe calk. This head 16 also carries a spring pressed plunger 23 vertically movable therein and adapted to engage the bar 9 above the slide 5 and close to the cutting edge thereof. This plunger is held in the head by a longitudinally movable screw 25 surrounded by a spring 24 to yieldably engage the plunger with the said bar whereby the bar is held down and kept straight when it is sheared by the cutting end 8 oli' the slide and the side angle ot the punch. This head also carries a wedge 2Q having an inclined surface adapted to engage the end wall 7 of the opening 5a in the slide 5 and as it descends moves the slide with its cutting end 8 properly located over the front of the shoe to sever the proper length of the bar 9 to form the toe calk.

Push bars 27 are provided vertically movable in openings in the bed plate operated by any suitable mechanism (not shown) to raise the shoe out from between the side dies 3 after it has beenoperated upon.

In ormingthe calk 28 and iin Q9 there is considerable side strain on the punch and to take this strain a wear plate or block 1b is inserted in the bed plate slidably engaged by the punch as it descends.

From the foregoing description the operation of my device will be readily understood. The blank Jfor the horse shoe as shown in Figs. 7 and 8 is heated to a welding heat at the toe and a forging heat throughout the remainder. The end of the steel bar 9 is also heated to a welding heat andplaced in the slide with its end against the stop 10. The press is now operated and as the head 16 descends, the punch shears off the end of the bar 9 and welds it to the blank and also forms the iin 29 and calk 28. At the same time the punches 18 drive the heel portions of the shoe between the side dies 3 swaging the same and forming the nail grooves 30. As the head 1G rises again the slide 5 is retracted and the formed shoe lifted by the pushers 27 and manually removed from the machine.
