MACHINE FOR MAKING SPIKES.

SPECIFICATION forming part of Letters Patent No. 440,095, dated November 4, 1890.

Application filed July 1, 1890. Serial No. 357,407- (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. WYLAND, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in a Machine for Making Spikes, &c.; 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 pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improved ma-- chine for making spikes, nails, rivets, &c.; and it consists of two disks suitably mounted and geared together, having interchangeable dies secured therein, formed to shape the head and point of the spike or nail, and the said dies provided with cutters to divide the bar into proper lengths, together with certain details of construction and combination of parts, as will be fully set forth hereinafter.

In the accompanying drawings, Figure 1 is 2 5 a face view or side elevation of my improved machine having the side roll removed therefrom. Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged detail View of a portion of the upper and lower disks, showing the arrangement of the dies. Fig. 4 isa plan view of one of the dies, together with a portion of the lower disk and side roll. Fig. 5 is a side elevation of a railway-spike, such as would be formed by the dies shown in the drawings. Fig. 6 is a side view of an ordinary boat-spike. Fig. 7 is a side elevation of an ordinary rivet.

To put my invention into practice, I provide a strong frame or housing a, of suitable size and form of construction, and mount therein in suitable bearings two shafts b, the one located above the other and geared together by two toothed wheels 0, meshing With each other. These two shafts 1) project through the frame a, and are each provided with a disk or roll (Z e, having interlocking male and female buds f g, to prevent any side movement. Formed in the face of each of these disks (1 e are a series of dovetailed pockets for thereception of a series of dies and cutters h t. These dies h i consist of a dovetailed piece of steel adapted to fit neatly into the pockets, and are adjusted by liners placed at the base and .held rigidly in position by means of set-screws j, passing through a slot k, which extends through the dies h 'i and in the direction of its length. The die 2' in the upper disk 6 is provided with a recess Z to form the rear portion '6 of the head of the spike s and a downwardly-extending knife m for shearing the spike-bar n. The several dies h in the lower disk d are each provided with a recess 0, which forms the front portion 13 of the head of the spike s, and with a cavity p for the reception of the cutters m of the upper die 0.

The chisel-point t of the spike s is partly formed by the heel or rear portion of the cutters and partly by inclined parts or projections g on the working portions 5' of the two disks d e.

Mounted on a vertical shaft- M, which is geared by means of small bevel-wheels 'u to the upper horizontal shaft 1), is a small roller 10, which occupies a position immediately at the front of the intersection of the two disks d e, and is used to prevent any lateral spread of the bar n while being converted into spikes. This roll to is provided with a series of recesses 0a, which forms one side q of the head of the spike 3, while a similar series of recesses 0, formed in the face or side of the dies 77. 2', (see Fig. 4,) forms the other side q of the head. These last-mentioned recesses a: c, together with those Z 0, formed in the dies h i, meet at the same time, which will form a perfoot head. At the front of the disks is a guide .2, supported by a cross-bar to insure or guide the bar n into the groove 8, formed by the junction of the three rolls d e w. 9c

In operation a bar of iron n, rectangular in cross-section, is heated and one end entered between the disks d 0 through the guide, the inclined surfaces q pressing a point on the same, and the bar reduced by the several 5 rolls to form the body of the spike. The head is pressed by the dies d e and the bar cut by the knife. By applying power to the shaft b,

carrying the lower disk (1, motion is imparted to the upper disk 6 and to the side roll w by too means of the connecting gear-Wheels c t, which gives the three rolls cl 6 w a continuous rotary movement. By entering a bar of iron n such as described, and at a proper heat, the same is rapidly converted into spikes, or by a slight modification of the several dies into rivets or other like articles.

Having thus described my invention, I claim The herein-described machine, consisting of the two disks d e, mounted on shafts b, the one above the other and suitably geared together, a horizontal r011 w, operating at the intersection of the said disks d e, provided with recesses w to form one side of the head of the spike, a series of dies h i, placed at regular intervals about the periphery of the said disks d 6, each of which is provided with a means for forming a part or portion of the head, and each provided with cutters m 19, whereby spikes or rivets may be formed, substantially as described.

In testimony that I claim the foregoing I hereunto affix my signature this 23d day of June, A. D. 1890.

WILLIAM H. WYLAND. [L. s.]

In presence of JOHN C. THOMPSON, RICHARD S. HARRISON.
