MACHINE FOR MAKING HORSESI-IOES.

Specification of Letters Patent.

Patented Dec. 7, 1909.

To all whom 'it may concern:

Be it known that I, RUFUS S. MATTEsoN, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain newY and useful Improvements in Machines for Making Horseshoes,

of which the following is a specification,.ref

erence being had therein to the accompanying drawing.

This invention relates to the manufacture of horse shoes and has for its object to provide a machine to which bars of iron the length of a horse-shoeare fed, these bars being acted upon and formed with the necessary grooves and bevels, also with the nail holes made therein, then automatically bent into the desired form and dropped out a completed shoe.

With these objects in View the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying` drawings: Figure l-is a plan View of my improved machine. Fig. 2-1s a sectional elevation through the machine on the line traversed by the shoe blank, showing the two sets of rotatable dies and the feed rolls by means of which the shoe blanks are fed through the machine and carried to the bending mechanism at the left. Fig. 3illustrates a section on line 3 3 of Fig. 2 through one of the dies and its supporting plate. Fig. iis a View showing the blank in position to be bent by the forming block, which die is in its eXtreme rearward position. Fig. 5-illustrates the die block as being moved forward forming the blank around the same, and in a position just before it has completed its forward stroke, the completed forward stroke being illustrated in Fig. 1. Fig. 6-shows a cam actuated by the backward movement of the forming mechanism whereby the positioning plates are drawn apart to receive the blank, which plates are automatically caused to engage the ends of said blank when released by said cam to hold the same ina central position to be acted upon by the forming block. blank. Fig. S-is a sectional view on line 8 8 of Fig. 7. Fig. 9-is a view showing the edge of the first rotating die working in conjunction with the lower backing roll to form the horse-shoe blank. Fig. lO-is the Fig. 7-shows the shoeV second rotating die which finishes the beveling, the recesses and the holes in said blank.

Referring to the drawings, at 1 is the frame of the machine on which is mounted the operating mechanism. At 2 is the countershaft on which is mounted the driving pulley 3 and the pinion 11. This pinion meshes with the large driving gear 5 which is mounted on the shaft 6. Also mounted on this latter shaft is the rotatable die block 7 which roughs out or makes the first impressions on the shoe blank. At 8 is a backing roll geared to run in time with the die roll shaft and arranged to receive the pressure of the die block as the same is making its impressions in the blank, and also beveling or shaping a shoe at the underside into the desired form. A second or finishing die block 9 is mounted on the shaft 10 which is driven in time with the first die block through the gears l1, 12 and 13. This second die block also has a backing roll 9a driven in time with it. The upper feed roll 14 is driven through the sprocket chain 12a from shaft 6 and is arranged to engage the blank and carry it from one die block to the other along the guide trough 53. The feed rolls 15 and 16 receive the blank from the second die and deposit it in position to be engaged and bent into the desired form. rlhese latter rolls are driven through the

sprockets

28, 29, 30 and 31, and the sprocket chains 32 and 33.

The first die block 7 is designed to bevel the blank slightly at 17, in the manner best illustrated in Fig. 9, forming two grooves or impressions 18-19, see Fig. 7, by the raised

portions

20 and 21 on the face of the same. Each die block is preferably made separate from its bearing member 22 and is secured to the sameby means of the setscrews 23-23 through the ears 2li-*24. The second die block 9 is similar to the first block 7, the only difference being that the beveled portion is made a little deeper as at 25, see '.Fi'g. 10, and the pins 27 are a little longer so that the holes 26 may be punched entirely through the blank for the reception of the nails.

At 55, see Fig. 2, is a sliding gage which may be drawn out and set to receive blanks "of dierent lengths. At 56 is a stop lever with a counterweight 5S whereby-said end is normally held up in its engaging position. At 59 is a cam located on the periphery of the circular plate 60 which carries the second die. As this plate revolves the cam comes in contact with the lever 56 pressing the same downward and allowing the blank to be carried forward by the action of the feed rolls into engagement with the second die block 9.

In the bending portion of the machine the centering plates 34 34 are adapted to slide toward and from the center, the outer ends of these plates being engaged by the connections 35-35, see Fig. 2, the lower' ends of which connections are fixed to the shafts 86-36, see Fig. 4. Also fixed to these shafts 36 are the arms 37-37 which are pivoted together at their inner ends, and a cam portion 38, for engaging said arms, see Fig. 6 is carried by the bar 39.

Then the shoe blank 40 is fed to the bending device the form block 41 is withdrawn into the position illustrated in Fig. 4. At the rear end of the stroke of this form block t-he cam 38 is caused to engage the arms dT-37 to raise them substantially into the position illustrated in dotted lines in Fig. 2, thereby rotating the shafts 36 and drawing apart the centering plates 34-34 preparatory to receiving a shoe blank. After these plates have been drawn apart a shoe blank is deposited by the feed rolls into the position illustrated in Fig. 4, then as the form block starts to move ahead, and before it engages the blank, the cam 38 is withdrawn from the arms 8T allowing them to drop of their own weight assisted by the tension of the spring 42, thereby carrying the centering plates inward engaging the blank and moving it to the exact central position where it is directly engaged by the forwardlymoving form block and carried through the opening between the plates 423-43 and bent into the form illustrated in Fig. 5. Just before the termination of this forward stroke the cam portions 44-44 engage the rolls 45-45, which are mounted on the pivoted levers 46-46, carrying these ends outward and at the same time carrying the opposite ends 47-47 inward to press the ends of the shoe blank tightly around its form block, thus completing the formation of the shoe. The form block is then withdrawn carrying the shoe with it over the opening 4S through the bed where the shoe is dropped off completed. The reciprocating motion is given to this form block from the shaft l0 through the beveled gears 49, shaft 50, crank 5l and connection 52.

The operation of the invention may be more fully described as follows: rIhe machine may be driven continuously from any desired source of power through a belt, not shown, and the pulley 3, the rolls all being suitably geared together to run in time with each other. Short bars of iron of the desired size and length after being heated, are placed one at a time into the guide trough one end resting against the adjustable sliding gage 55, said gage having been previously set to receive the required length of blank and hold it in position to be engaged at the proper time by the first die. As this die block revolves it comes in Contact with the blank and operates upon it at the same time carrying it forward until its front end is forced between the feed rolls 14-14 which continue to move the same toward the second die until its forward end brings up against the stop 56. .lVhile the bar is in engagement with this stop the feed rolls continue to revolve and slip on said blank until the cam portion 59 presses down said lever and releases the blank thereby allowing` it to pass forward at the proper time to be acted upon by the second dies. It will be seen that by the action of this stop lever the second dies are always bound to engage the blank at exactly the right time regardless of the length of the blank.

By this construction it will be seen that blanks of any desired length may be passed through the machine and be autonlatically taken care of and not allowed to enter the second die until the same is in a position to receive them. By this arrangement the second die will always register perfectly on the work with the first die, which latter die finishes the blank by completing its shape and punching the nail holes through the same, after which said blank is carried forward by the other feed rolls and deposited into the bending machine where it is formed into the shape of the horseshoe, and then automatically deposited in a suitable receptacle in a finished condition.

The machine is practical in its construction and will form horseshoes rapidly and finish the same without the aid of skilled labor.

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

l. In a machine for making horseshoes the combination of a rotatable roughing die, a rotatable finishing die, means for rotating said dies in unison, means located between said dies for feeding the blank from the roughing die to the finishing die, and automatically operated means located between said feeding means and said finishing die for positively engaging said blank to arrest the feeding movement thereof, and means actuated by the finishing die when the latter reaches an operative position to withdraw said arresting means, whereby said finishing die will register with the impression made by the roughing die.

2. In a machine for making horseshoes,

Mast/o the combination of a rotatable roughing die, a rotatable finishing die, means for rotating said dies in unison, means for feeding a blank from the roughing die to the finishing die, a withdrawable stop arranged to interrupt the passage of the blank between the feeding means and said finishing die, said feeding means being constructed to permit of such interruption, and means operated by said finishing die for withdrawing said stop, said withdrawing means being timed to cooperate with said nishing die, whereby the latter will register with the impression made by the roughing die. v

3. In a machine for making horseshoes, the combination of a rotatable roughing die, a rotatable finishing die, means for rotating said dies in unison, means for feeding a blank from the roughing die tothe finishing die, a pivoted finger arranged to normally interrupt the passage of the blank between the dies, said feeding means being constructed to permit of such interruption, and a cam carried by the finishing die for automatically rocking said finger to withdraw the same.

4. In a machine for making horseshoes, the combination of a rotatable roughing die, a rotatable finishing die, means for rotating said dies in unison, means for feeding a blank from the roughing die to the finishing die, a stop provided with a counterbalanced portion and arranged to intercept the path of movement of the blank between the dies, and means carried by said finishing die for automatically withdrawing said stop.

In testimony whereof I affix my signature in presence of two witnesses.
