AUGUST M. SVEDER, OF MARQUETTE, MICHIGAN, ASSIGNOR OF ONE-HALF TO ARTHUR UDDENBERG, OF SAME PLACE.

MACHINE FOR MAKING HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 386,904-, dated July 31, 1888.

Application filed December 31, 1887. Serial No. 259,475. (No model.)

To all whom, it may concern,.-

Be it known that I, AUGUST M. SWEDER, a citizen of the United States, residing at Marquette, county of Marquette, State of Michigan,have inventedacertain new and useful Improvement in Machines for Manufacturing Horseshoes; and I declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in 1o the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, which form a part of this specication.

My invention pertains to a novel machine r 5 for the manufacture of horseshoes; and it consists of the construction, arrangement, and combinations of devices and appliances hereinafter specitied,and more particularly pointed out in the claims.

The purpose of the machine embodying my invention is to provide an expeditious device whereby the manufacture of horseshoes may be easily and economically accomplished and their production not only increased in quanz5 tity, but also in their uniform quality, so as to be of superior efficiency. This purpose I secure, essentially, first, by providing the machine with devices for cutting from a bar of iron a bar of sufficient length as may be desired for forming the body of the shoe with its heel-calks; second, by providing the machine with presses of suitable form to shape the body of the shoe about an intermediate die or patternblock; third, by providing 3 5 mechanism to carry the clipped bar from the knife to said presses; fourth, by providing mechanism to operate said presses to secure the bending of the bar into the form of the shoe; iifth, by providing an auxiliary press to 4o turn the hcel-calks; sixth, by providing the machine with an additional press and stamp lo perforate the shoe for the reception of the nails, and to prevent the lateral spread of the metal in shaping the body ofthe shoe; seventh, by providing means for releasing the shoe from the machine when the process of its manufacture is completed; and,eighth,my invention embraces all other general and specifre construction and operation of parts illus- 5o trated in the accompanying drawings, which forma part of this specification, andas herein set forth.

In the drawings, Figure l is a side elevation ofa device embodying my invention. Fig.

2 is a vertical cross-section along the linem y 55 of Fig. 1. Fig. 3 is afront elevation showing portions of the invention. Fig. 4 is a separate view of the arm F, showing the bridge G in section. Fig. 5 is a separate view of the die in its pedestal in side elevation. Fig. 6 6o is a front view of the same with the shapingpresses in position thereon. Fig. 7 is a side elevation of a portion of the reciprocatory press; Fig. 8, afront View of the same. Fig.

9 is a front view of the stamp; Fig. 10, a side 65 View thereof; Fig. 11, a separate view of the bridges A and G,with adjustable mechanism. Fig. l2 is a separate view of the auxiliary press L.

I carry out my invention as follows: 7o

In the drawings, A represents any supporting bed and frame.

B is the driving-gear, mounted upon the driving-shaft B and meshing with the gear O, mounted upon the driving-arbor C', provided 75 with a series of eccentrics, as hereinafter explained, and also with a gear for` driving one of the presses, as further explained in its order. The eccentric c, located upon said arbor, is arranged to operate upon a reciprocatory bar, D, to depress said bar, the bar having a pivotal engagement, d, with a cutter-arm, D', which may be pivotally engaged at its opposite end upon a bridge, A@ as shown at a. rPhe cutter-arm is provided with a cutter-blade, D2, and any suitable retracting-spring, D3. Said arm is made open or bifurcated at its outer end to permit the passage of the metal bar E, supported upon the bridge A. lt is evident, thus, that when the reciprocatory bar D is depressed 9o by the eccentric c the metal bar will be severed by the cutter-blade upon the arm D', which arm will then be retracted into its normal position.

The severed end E', of suitable length to con- 95 stitute the body of the shoe with its heel-calks, is carried to the shaping-presses by means of a vibratory arm, F, having its upper end movable in a bridge, G, the construction and arrangement being such that as the head of the roo vibratory arm is thrown in the direction of said presses the severed end of the metal bar will be carried thereto.

The vibratory arm may be pivot-all y engaged,

as at f, upon the supporting-frame, its lower end projected beyond said pivotal engage ment, as shown in Fig. 1, to constitute a lever for the vibration of the arm. Thislever end of said arm has a jointed engagement, as at f', with a connecting-rod, F', united at its upper end with the arm H, operated by the eccentric c. As thus constructed, it will be seen that when the eccentric c' operates the arm H and its connecting-rod F' the vibratoryV arm will be thrown to carry the iron` to the presses. Said arm may then be retracted by any suitable spring, F.

I l' are the shaping-presses, having their faces curved into suitable form to shape the bar E' to constitute the body ofthe shoe, and flanged, as shown at i i', toreceive and retain said bar. Said presses are pivotally engaged at one end upon a supporting-pedestal, A2, and have a similar engagement at their opposite ends, as shown at i2 i, with suitable connecting-rods, respectively, .I J', which rods are operated by eccentrics c2 c3, respectively, on the arbor C. Thus the presses may be opened and closed, as shown in the two said4 positions in Fig. 1in full and in dotted lines, their position being actuated by the eccentrics c" c3.

Secured upon the pedestal A2 is a center die or pattern-head, K, its periphery being of the desired form of the shoe. This die or head may be made relnovable and engaged upon the pedestal in any desired manner to form a center bearing, about Which the metal is shaped into the proper outline of the shoe as the presses are operated.

Toform the heel-calks,IproVide an auxiliary press, L, pivotally engaged upon the said pedestal A2, as shown atl. This press is engaged ,pivotally intermediate of its extremities, as shown in Fig. 2, so as to havea suitable motion. At one end said press is engaged also with aneccentric, c4, upon the arbor C' by a connectingrod, M, having a jointed union with the press, as shown at m. The opposite end of the press is preferably forked, as shown in Fig. 12, and its forked extremities arranged to bear upon the extremities of the shoe and bend the metal to form the calks at the heel.

N represents a reciprocatory press eccentrically engaged at one end upon a shaft, O, by means of a sliding head, N', operating upon a supporting-bed, P. The eccentric engagement of said head upon said shaft is shown in Fig. 2 at u. This shaft is driven by a gear, O', meshing with a gear, O", upon the arbor C'.

Q is a stamp engaged upon the end of the press N, and held in place' in any proper manner, as by a set-screw, n'. The stamp is flanged upon its face to embrace the outer edges of the metal and prevent the yielding of the met-al. The stamp may also be recessed,

as at q, Fig. 10, for the operation ofthe shap ing-presses.

Within the recess q of the stamp are located a series of small punches, g3, for the purpose of perforating the shoe to receive the nails, and which is accomplished by the reciprocation of the press N. These punches may be removable. The pedestal A2 may be suitably perforated, as at a', to permit the ready discharge of the chips punched from the shoe.

To release the shoe any desired device may beused-as, for instance, an arm, R, may be engaged upon the bed P to throw off the shoe as the press N is retracted. The shoe naturally adheres to the stamp Q as the press is drawn backward. I prefer, however, a construction shown in Figs. 7 and 8, where the press N is shown provided with thebars Rengaged in the orifices g* of the stamp and provided with retracting-springs r. The inner ends of said bars are made to abut against a stationary yoke, N, engaged upon the pedestal or bed P, as shown at n2. It will be seen that as soon as the press moves rearward the heads of the bolts will crowd the shoe oft.

It will be seen that the bed P and pedestal A2 are but parts of the general bed or frame A.

By making the pattern-head K and stamp Q removable others of desired size may readily ta'ke their places for the manufacture of different-sized shoes. For this purpose it is also desirable to make the presses I I' removable. Accordingly, said presses and the head K may be removably engaged upon the pedestal' Az directly; but I prefer to engage said devices upon a removable face-plate, K', engaged upon said pedestal. Moreover, in the manufacture of various sizes of shoes, it will be necessary to control the length of metal to be cut from the bar E. This may be done as follows: The bridge G, as shown in Fig. 11, may be provided with an adjustable stop, g, operated by a suitable lever, G', pivotally engaged or fulcrumed upon said bridge, as at g',

said lever at its outer end movable along an arc, a2, upon the frame, said arc provided with an elongated slot, in which the lever may be setV at any desired point by a set-screw, g".

By a proper mechanical arrangement and adjustment of parts the different steps in the process of manufacture of the shoes may be made to take place consecutively in desired relation and order with accuracy and precision. The various features are simple in con-v roo struction and operation, not likely to get out y of order, and thereby a considerable number of shoes may be turned out per minute and perfect in their construction.
