SPECIFICATION forming part of Letters Patent No. 394,223, dated December 11, 1888. Application filed October 20, 1888. Serial No. 288,675. (No model.)

.To LLZZ whom may concern:

Be it known that I, WALTER JUDsoN STE- VENS, a citizen of the United States, residing at IVhitesviIle, in the county of Allegany and State of N ew York, have invented new and useful Improvements in Olivers, of which the following is a specification.

My invention relates to improvements in olivers; and it consists in certain novel features hereinafter described and claimed.

The primary object of my invention is to provide means whereby the hammer can be readily adjusted to work upon any desired part of the anvil.

A further object of the invention is to improve the construction of the device, whereby it can be more easily and rapidly operated than the devices heretofore employed.

These objects I accomplish by the use of the mechanism illustrated in the accompanying drawings, whereinn Figure 1 is a side elevation of an oliver. 2 is a front view showin the manner of adjusting the hammer to play on different parts of the anvil. Fig. i is a detail perspective view of the rock-shaft.

Referring' to the drawings by letter, A designates the anvil, sujrportcd upon a suitable base, B, of the usual or any preferred constructioi'i. From 011e side of the base a pin, C, projects laterally, the purpose of which will presently appear, and to the same side of the base, adjacent to the said pin, I secure a guide, D, which will be presently more fully referred to. At a suitable distance from the base I erect the standards E E, which are connected by a cross-brace, F, as shown, and have bearing-boxes G secured to their upper ends. A rock-shaft, H, is journaled in the bearing-boxes G, and has one end projected beyond the adjacent bearing-box and provided with a crank-arm, I.

J designates the operating foot-lever, which is pivoted at one end to the side of one of the standards E, and extends forward from its pivot through a guide, K, secured to the side of the said standard, to a point near the front side of the base B, where it is widened laterally to form a foot-rest or pedal, L, as shown. The front end of this operating-lever plays in the guide D, the said guide and the guide K securing a true vertical movement of the lever in operation. A spring, II, is secured to the upper side of this lever, and its free end is adapted to contact with the pin C, projecting from the base, so as to serve as a buffer and stop to limit the upward movement of the lever and deaden the force of the contact between the lever and the said pin.

N designates a connecting-rod having its lower end pivotally secured to the operatinglever and its upper end engaging one of a series of transverse openings, O, in the crankarm I of the rock-shaft. By this connection, when the lever is depressed, t-he rock-shaft is rotated, as will be readily understood, and the hammer thereby brought down upon the anvil, and the blow given by the hammer can be varied by causing the upper end of the connecting-rod to engage one or another of the openings O, as will be readily understood.

P designates crank-arm formed integral with 'the rock-shaft and projecting rearward therefrom at aboutthe center of the same, and provided with a series of transverse openings, Q, one of which is engaged by the upper end of a spring', R, which has its lower end secured to the lHoor of the shop or any other fixed point. This sprin serves to return the roclcshaftto its normal position and raise the hammer, after the same has been brought down upon the anvil, by means of the operating-lever and connecting-rod, as above referred to.

S designates a sector-plate formed integral with and projecting upward from the rocksha-ft, and having a series of notches, T, in its upper curved edge, as shown. The hammer U is pivoted to the sector-plate by means of a pivotal bolt, V, passed transversely through the said plate and the end of the hammer, as shown. A sliding latch, IV, is mounted on the handle of the hammer, and

the end of the same engages the notches T of the sector-plate to lock the hammer in the desired position. The said latch is held normally in engagement with the said notches by means of a coiled spring, X, arranged around the latch between a pin, Y, inserted transversely through the same and a lip, Z, at the end of a casting, a, the said casting being provided at its opposite end with a tongue, h, which rides over the curved edge of the IOO sector-plate and thereby prevents the end of the latch moving laterally from the notches. The lip Z and the said tongue b serve, also, to guide the latch into the notches, as will be readily understood. In order that the latch may be disengaged from the notches, I provide the free end of the same with a spur or handle, c, as shown.

Such being the construction and arrangement of the parts of my device, the operation and advantages of the same will be readily understood.

The metal to be operated upon is held upon the anvil in the ordinary manner and the smith operates the device by depressing1 the lever with his foot. The hammer is thus brought down upon the metal, as willbe readily understood, when the pressure on the lever being removed the spring automatically returns the hammer to its normal raised position to permit the meta-l to be turned or otherwise shifted, as may be required. \Vhen it is desired to work the metal at the center of the anvil, the latch on the handle of the hammer is engaged in the central notch of the sector-plate, as shown in Fig. 1. Then it is desired to work the metal upon the horn or the heel of the anvil, the latch is disengaged from the central notch and the hammer is then swung upon its pivot to one side or the other and the latch engaged with one of the notches to hold the hammer in its adjusted position. The device is then operated in the manner before described, as will be readily understood.

It will be observed from the foregoing' description, taken in connection with the accompanying drawings, that I have provided a very simple device, which is composed of few parts, which is free of all complicated combinations and arrangements, and which can be manufactured and sold at a smal cost.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-- l. In an oliver, the combination of the rockshaft, the sector-plate projecting therefrom,

the hammer pivoted to said sector plate, mechanism for locking the hammer to the said plate, and mechanism for rotating the rockshaft, substantially as set forth.

2. The combination of the rock-shaft, the sector-plate projecting therefrom, the hammer pivoted 011 the sector-plate, the latch mounted on the handle of the hammer and engaging said sector-plate, and mechanism for rotatin g the rock-shaft, as set forth.

The combination of the rock-shaft having a crank-arm projecting from its central portion, the sector-plate projecting from the said shaft, the hammer pivoted on the said sector-plate, the latch mounted on the handle of the hammer and engagin said sectorplate, the spring secured to the crank-arm of the rock-shaft to rotate the same in one disection, and mechanism for rotating the rockshaft in the direction contrary to that of the spring, as set forth.

4. In an oliver, the combination, with the base B, having the pin C projecting laterally from one side, of the operating-lever having a spring secured to its upper side and adapted to contact with said pin, as set forth.

5. The combination of the standard, the rock-shaft mounted on the upper ends of the same and having a crank-arm, I, at one end and the crank-arm I) at its center, the spring secured to the crank-arm P, the hammer carried by the rock-shaft, the lever pivoted at one end to the side of one of the standards and projectingforward beyond the same, and the connecting-rod having its lower end pivoted to the lever and its upper end adjustably secured to the crank-arm I, as set forth.

G. The combination of the rock-shaft, the sector-plate projecting therefrom, the hammer pivoted on the sector-plate, the casting having the tongue I; riding over the edge of the sector-plate, the latch engaging the sector-plate, and the spring coiled around the latch and adapted to hold the same normally in engagement with the sector-plate, as set forth.

7. The combination of the standards, the rock-shaft mounted thereon, the hammer carried by the rock-shaft, the guide K, secured to the side of one of the standards, the base having the pin C and the guide y D on one side, the operating-leverpivoted to the standard and projecting forward through the guides K and D, the spring secured to the upper side of the lever and adapted to contact with the pin C, and the connecting-rod extending vbetween the lever and the rock-shaft, as specifled.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

XVALTER JUDSON STEVENS.
