Letters Patent No. 110,756, dated January 3, 1871.
IMPROVEMENT IN SPIKE-MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
I, DAv1D'EYNoN,cf Richmond, county of Henrico, State of Virginia, have invented an Improvement in Spike-Machines, of which the following is a specification.
Nature and Object of the Invention.
Description of the Accompanying Drawing.
Figure 1 is a plan view of suicient of a spike-ma# chine, with my improvement.

General Description.
A and A are the side-frames of a spike-machine for which Letters Patent were granted to Jas. H. Swet-t April 3o, 1861.
B is the driving-shaft, from which a vibrating motion is imparted to the shaft E through the medium of the crank C, rod D, and arm F.
From the shaft E a vibrating motion is imparted to another' shaft, K, through 'a crank, G, having an adjustable pin, which is connected by a rod, I, to an arm, J, on the said shaft K, the latter carrying another arm, t', connected by rods e e to the slide T, which vis arranged' to move to a limited extent on a slide, R, the latter being adapted to guides on the frames A and A'. v
'lo pins on the slide It are jointed the nippers Q Q, by which the nearly-severed end of a hot bar is torn oif and carried to a proper position to be acted on by the griping-dies prior to the heading of the spike by a bar, M, actuated by arms on the shaft E.
All the above-mentioned parts are to be found in Swetts patent machine.
In adjusting the machine for making spikes of different lengths, it becomes necessary to impart a longer or shorter reciprocating motion tothe nippers. This I also accomplish substantially in the same manner as 'described in Swetts patent, that is to say, by the adjustment of the .pin which connects the rod 1 to the crank G further from or nearer to the axis ofA the shaft E. But. the simple adjustment -of the pin only is insufficient to effect all ofthe changes that may be necessary; for instance, after the adjustment the point of the nippers may seize the piece of the bar too far behind the end of the same, in which case there will be too much metal for the desired head, or there may be too little metal for that purpose, and hence there should be, in addition rto the devices for increasing or diminishing the extent of movement of the nippers, other devices by which, while the extent of movement remains the same, the nippers may be caused to grasp the blank at any point nea'rer to or remote from the end, so that the length of that portion ofthe blank left projecting beyond the dies, of which toform the head, may be varied at will, and my improvement con-V sists in the arrangement of devices by which this lastnamed adjustment may be effected. 'Ihus I make each rod with an elongated opening, as shown in iig. 3, adapted to a bearing, n, for one of. the pins, thepostion of this bearing being controlled by a screw, x, in a manner which will he reaily understood .by referling to iig. 3, so that by operating the screws the rods may be lengthcned and shortened at pleasure, and the movement of the ni'ppers` restricted in its range accordingly.
It is not essential that there should be two adjustablerods e e, as one rod of proper strength may serve the desired purpose. Nor is it essential that the adjustability of the rod should be effected through the medium of the movable bearing controlled by a screw inL the manner described, as other plans may be adopt-A ed for lengthening or shortening a rod or rods, withl out departing from the mainY features of my inven- '(-OIL Claim.
-The slide R., carrying nippers Q Q, and the slide T; having a limited sliding motion on'the slide R, and operating said nippers, in combination with a shaft, K, its crank i, connecting-rod or rods c, and mechanism, substantially as described, for adjusting the length of said rod or rods:
I n testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
DAVID EYN ON.

CHARLES FOSTER, WM. A. STEEL.
