FERDINAND Davison,r or LIBERTY, VIRGINIA.

Letters Patent No. 87,47 4, dated March .2, 1869.

To all whom it may cozwern Be it known that I, FERDINAND DAVIsoN, of Liberty, in the county of Bedford, and in the State of' critters will be so placed as to cnt the proper point on the spike, and in pressing the point by the proper bev; els in the diev to its right place on the centre line of the spike; also in the arrangement for feeding the rod to carry this bar into the machine. As soon as the end the cutters.

In order to enable others skilled ir. the 'art to which my invention appertaius, to make and use the same, I

will now proceed to describe its construction and operation, referring to the annexed two sheets of drawings, which form a pax-trof this specification, and in'.

Which-- Figure 1 is a plan view;

Figure 2, a side elevation, showing the feeding-arrangement; y

Figure 3 is a side elevation, in section, taken through the line :t :c

Figure 4, an end view, in section, taken through the line y y and v Figure 5 is a front view of the movable cutter-plate and cutter.

This cutter-plate is provided with tongues along its sides, which tongues fit in grooves on the sides ofthe frame A, thus allowing the plate to slide back and fort on thesame level exactly.

On the under side of the said cutter-plate G, is secured the cutter H,'as shown in lig. 5, which cutter is bevelled, as shown, on one side, to cut the point of the spike at the proper point.

The cutter-plate G and cutter H rest on a bed-plat`c,

lI, of such width as to correspond with the length of the spike intended to be cut.

The bed-plate l is, along its inner edge, provided with a. ange, against 'which the end ofthe rod from which the spikes are cut, is placed. The iiange on-the bedhlate I ts into a groove on the under or lower side of the cutter-plate G.

Oni-the side of the frame A are placed three forked arms J J, in which a shaft, K, has its bearings. This shaft is, at its rear end, provided with a suitable number of teeth, a a, which are operated upon by an arm, L, secured to the shaft C, so that, for each revolution of the main shaft G, the shaft K is turned the distance of one of the teeth a.

The shaft K is, at a. suitable point, provided with a roller, M, bet-Ween two of the arms J J, and over this roller is another roller, N, resting on the same, and having its journals placed in the same arms, J J. 0n the outer side of these two arms, and between the rollers M N, is placed a plate or block, 0, which is grooved 'for the insertion of the bar or rod from which the spikes are to be cnt.

Vhcn the machine is in operation, the rollers will of the bar emerges on the other or inner side of the two rollers, it passes into a groove or channel in another.

plate or block, P, which is cnt, as shown in iig. 1, so that the part of said block in front of the channel extends further inward than the other, and is bevelled, to correspondwith the cutter Hrthe edge being also sharpened, so as to form a cutter.

The two rollers M Nfeed the rod or bar, so that the end thereof strikes or rests against the flange on the* plate I, when 4the cutter H cuts it olf, and carries the cut-oil' piece forward; then, as soon as the cutter-plate' G moves" backward, the rollers carry the rod inward again, so as to be ready for the next forward movement ofthe cutter.

It will be seen that the bevelled and sharpened part of the. plate P acts as an additional cutter, and when the bar is in its place, as above described, and the cut,

ter H moves forward, the blank for the spike is entirely out olio from the bar.

The cutter H, and bevelled and sharpened part of the plate P, are so arranged as to cnt rtbe proper point on the spike at the same tirnae'as the blank is cut off; that is, the blank is cut oli" in the proper shape for the point. I

After the rst blank has been cut off from the rod or bar, the following blanks, it will be seen, are in the shape'of a rholuboid, having a point at each end, one of which is afterward formed into the head, and the other forms the point of the spike. The rst blank, however, would, if the rod were square at the end, have more niet-al in the head than the succeeding ones. To insure uniformity, I may therefore first cut the end of the rod inh proper shape, so that the rst blank will correspond with the shape ofthe rest.

When the spike is thus cut, it is carried forward by the cutter-plate G, ou the bed-plate I, and depositedin onc of the notches 'L i, on the roller R, said roller being so placed on a-sliaft, S, which has its bearings in the sides of the frame A, that the spike, after being deposited in one of the notches, will project suticiently on the inner side of the saine, to form the head.

The outercdgc of the roller R, which properly may be called a die, is bevelled where the point of the spike is placed, and the pressing-roller T is provided with a ange to correspond therewith, so that the point of the spike will be placed on the centre line of the spike. Thisiismore plainly shown in fig. 4.

The pressing-roller or die Tis placed on a shaft, having proper bearings above and forward'of the die R.

The shaft S, with the die R, is turned by a pitman, V, which connects the. eccentric or cam-wheel E with a movable collar and arm, W, said collar being placed around the shaft S, and the arm provided with a spring-.

pawl or dog, working in cogs on the shaft, all arranged in such a manuel', that for each revolution of the main shaft C, the die It is turned' sniicicntly to place one of the notches i i in position 'to receive the spike..

On the side of the frame A, opposite to the side where the feeding-apparatus is located, is placed ahox, X, in which the punch Y is arranged in such a manner that the end thereof will press that end of the spike which projects beyond the notch in the die R, asv already described, and form the headof the spike.

The punch Y is operated by the wedge Z, which is connected, by means of a pitman, A', to an eccentric or cam-wheel, B', placed on the main shaft C, outside of the frame A.

Afterthewedge Z has pressed the. punch Y inward, and moves back', again, a spring, D', carries the punch Y out again, ready to be operated upon by the next forward movement of the wedge.

'After the spike has been thus completely formed by the dies and punch, it remains inits notch on the die` It, until the said die has been turned far enough around, so that the head-of the spike strikes against a bar, E', placed under the die, when the spike drops out.

Having thus fully described my invention,

- What Iclaim as new, and dsire to secure by ters Patent, is-

1. The form and construction of the holding and pointing-dies, on the rolls R and T, as and for the purpose specified.

42. 'lhe combination ofthe carrying and pointing-rolls R and T, with the bevelled' cutter and holder-block P and reciprocating cutter and transferrer H,- all arranged and operating together, substantially in the manner described. i

3. In combination -with subject-matter of second clause, the mechanism herein described, for feeding the blank-harto the knives, as set forth.

In testimony that I. claim the foregoin g, I have hereunto set my hand, this 19th day of September, 1.86.8.
