\VILLIAM HULTGRAN, OF PULLMAN, ILLINOIS.
SPIKE-MACHINE.
SPECIFICATION forming part of Letters Patent No. 304,327, dated September 2, 1884.
Application filed September 5, 1883. (No model.)
To aZZ whom it may concern:
. Be it known that I, \VILLIAM' HULTGRAN, a citizen of the United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spike-Machines, of which the following is a specification, to wit:
This invention relates to an improvement in machines'for making spikes; and it consists in certain details of theconstrnction and arrangement of the same,whereby the machineis made simple, strong, and of large capacity, substantially as will be hereinafter more fully de scribed, and pointed out in the claims.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure 1 is a top plan view; Fig. 2, a bottom'planview. Fig. 3 is a longitudinal vertical section. Fig. 4 is an end view; Fig. 5, a detail view of the cutting-dies and their operating mechanism; Fig. 6, a detail view of the levers for operating the pointingdies. Fig. 7 is a view of the pointing-dies. Fig. 8 rep resents the manner of operating the feeding devices, andFig. 9 shows the feeding-dog.
A- represents the base or frame of the machine, which is cast in one or more pieces, as may be rounamost desirable. In boxes a a, upontnejend of the main frame, is journaled the main driving-shaft A, upon one end of which is the fiy-wheel A and upon the other the driving-pulley A.
Upon the upper part of the machine, near its rear side, is placed a reciprocating bar, B, sliding back and forth in guides b b on the frame, and having one end broadened out and formed with a horizontal slot, 1), through which the main driving-shaft passes, and at this point thereciprocating bar is also formed with a vertical slot, b each end of whichis provided with an anti-friction roller, b 19, against which works the periphery of a heart-shaped cam, B, secured on the driviiigshaft and turning in the vertical slot b by means of which an irregular reciprocating motion is given to thebarB to operate most of the mechanism, as will be presently understood.
To the main frame, beneath the sliding bar B, a short distance from its outer end, is pivoted .upper side of this lever, near its rear end, is
furnished with a stud, c, engaging with a slot, (1, in the end of a lever, D, above the lever O, and fnlcrumed upon abar or frame, D, and having its forward end also formed with a slot, (1, engaging with a stud or pin, If, upon the reciprocating bar B, from which it receives a rocking motion upon its fulcrum, as will be understood clearly by reference to the drawings. The inner end of the lever G is formed with a nose, o engaging with a semicircular recess, 6, in the back of the casting E, which is provided or formed on each end withabeveled die for formingone side of the pointof the spike, and is arranged to have a reciprocating motion longitudinally of the machine in suitable guides or ways.
It is obvious that the casting E may be formed of steel, and the dies integral therewith, or it may be provided with removable dies, as may be desired.
To the main frame, opposite each end of the To the bar B, upon either side of the lever D, is pivoted one endof a lever, G, fulcrumed upon the main frame, and having the forward or shorter arms formed with an angular slot, g, which engages with a pin or stud, 9, upon one end of a lever, G, fulcrumed on the frame, and its. opposite end connected to a sliding head, H, which is thereby given a reciprocating, motion transversely of the machine in suitable guides, and provided with a hammer, II, which heads the spike, as will be hereinafter explained.
In a slot formed in the center of the bedplate A, just in front of the reciprocating die E, is placed an oscillating arm, I, pivoted being the operation of heading and pointing it,
and having upon its rear face two pivoted spring-actuated hooks, it, which project beyond its sides, and as it moves from side to side engage with clearing-fingers I hinged below the bed -pl ate, and extending up through it in a recess of the die F behind the spikeblank. Each of these clearing-fingers I is formed at its lower end with an angular arm, '01, provided with a spring, '5 adapted to return the finger to its normal position as soon as released from engagement with the springhook c.
Upon the upper end of the arm I is a box, I, connected by a pitman, J, with a frame, J,
sliding in suitable guides, j, upon the frame or bed, and surrounding the main drivingshaft, upon which is a segment-cam, J as clearly shown by Fig. 3.
In front of the oscillating arm I is placed the cutter-head K, arranged to have a longitudinal reciprocating motion upon the bedplate, and provided with a removable knifeblade, K, upon each end, which cut the blanks against the hammers H, as will be understood by reference to Fig. 1. The head K is formed with a downwardly-projecting arm, k, which passes down through the slotted bed-plate, and is connected by a bar, K with an arm, L, extending downward from a frame, L, sliding in guides upon the bed, and formed with a horizontal slot, 1, surrounding the main shaft, and with a vertical slot, Z, having frictionrollers Z in which works a heart-cam, L upon the main shaft, to give motion to the cutterhead.
In front of the cutter-head the bed-plate is provided or formed with two transverse guides or grooves, m, in which work two plates or feeding-heads, M, in close relation to the hammer-heads. These plates are each provided with a projection, m, to which is pivoted a dog, M, adapted, when the slide is drawn back, to slide over the blank rod which lies beneath it, and when the slide is projected forward to bite and feed the blank into the machine a distance suflicient to make a new spike. Each slide M is connected by a rod, m with avertical lever, M fulcrumed on the front of the machine, and connected at their lower ends by rods m m with a triplearmed oscillating lever, N, fulcrumed on the rear of the machine beneath the bed-plate. This lever N is formed with one central arm projecting rearward, and two side arms projecting upon either side of its pivoted point, to which latter the bars m m are-secured. The rear or central arm is formed with an eye, a, in which engages the lower end of a lever, N, fulcrumed on the frame, and its upper arm is provided with aneye, a, which engages with the nose 0 of the rocking lever G, which, by theintermediate mechanism just described, imparts an alternate reciprocating motion to the feeders M M.
In operation, the blank having been fed into the machine far enough to make a spike, the motion of the main shaft through its position by means of its spring the oscillating arm I to clamp the blank in position in the recessed die F, and the cam L throws the cutterhead K forward to cut the blank bar, and draws it immediately back again. The bar B is now again started forward, and by the intermediate mechanism the heading-hammer H is thrown forward and the die E is forced up to point the spike. The two are then drawn back by the reversal of the bar B, and thecam J draws back the arm I. Its dog or hook i being engaged with the clearing-finger I pulls it outward to clear the spike and deliver it through the bed. The finger is then released, and is thrown back to The reversed motion of thebar B operates the form'- ingdies upon the other side, and it will thus be seen that two spikes are formed with every revolution of the driving-shaft.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a spike-machine, a main driving-shaft j ournaled on the main frame, and provided with two heart-shaped cams, a bar or slide reciprocated by one of said cams, and a system of compound levers connected to and operated by said slide, in combination with a pointing-die, a heading die or hammer, and a cutter connected to said levers, and each adapted to have an irregular reciprocating motion to and from the spike under operation at stated intervals, substantially as and for the purpose set forth.
2. In a spike-machine, a main driving-shaft carrying a heart-shaped cam revolving in a sliding frame upon the bed, and a sliding bar connected to said frame, in combination with a series of levers connecting said bar to a reciprocating feeding-block having devices, substantially as herein described, for clutching the blank on its forward motion and freeing it on the backward motion, as shown and described.
