SPECIFICATION forming part of Letters Patent No. 357,255, dated February 8, 1887.
' Application filed October 26, 1886. Serial No. 217,277. (No modcll To all whom it may concern: Be it known that we, ARTEMUS \VELSH'aDd ELMER IVELsH, citizens of the United States,
residing at Scottdale, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Improvement in Olivers, of which the following is a specification.
Our invention relates to an improvement in olivers; and it consists in the peculiar c011- struction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.
In the drawings, Figure 1 is a perspective view of an. oliver embodying our improvements. Fig. 2 is a detailed sectional view of the same taken on the line x :10 of Fig. 1. Fig. 3 is a similar view taken on the line y y of Fig.1. Fig. 4 is a detailed perspective view of the bottom and upper dies used for shearing.
A represents an anvil,which is provided on its upper side with a horizontal transverse dovetailed groove, 13.
Crepresents a die which is placed on the upper side of the anvil, and is provided on its under side with a dovetailed tongue, D, that fits in the groove B. This enables the die to be very readily removed from the anvil when desired. I
At a suitable distance from the anvil is secured the frame E of the oliver, comprising the vertical sides or standards F, the rear-. wardly and upwardly inclined arms G, project ing from the said sides or standards, and the cross-bar H, connecting the outer ends of the said arms. In the upper ends of the sides or standards are bearing-boxes I, in which is journaled a rock-shaft, K.
L represents a rocking arm, which projects from thefront side of the rockshaft. A spring, M, connects the cross-bar H with the rocking arm, and serves to balance the latter and to normally raise it to an elevated "osition, as shown in solid lines in Fig. 1. The outer end of the rocking arm is provided on one side with a depending web or plate, N, having a curved slot, 0.
P represents the hammer, which is provided on its upper side with a vertical transverse groove, It, to receive the outer end of the rocking arm. A pivotal bolt, S, passes through transverse openings which are made in the upper side of the hammer and in the outer end of the rocking arm, so as to pivot the hammer to theonter end of the rocking arm and adapt it to turn or incline longitudinally thereon.
T represents a bolt, which extends through the slot 0 and through a transverse opening made in the hammer, and on the inner threaded end of the said bolt is screwed a clampingnut, U, the function of which is to tighten the bolt so as to clamp the hammer to the web or plate N at any desired longitudinal inclination. In the under side of the hammer is a transverse dovetailed groove, V. A die, \V, has on its upper side a dovetailed tongue, X, to enter the groove V, and thus secure the die to the under side of the hammer. A treadle, Y, isconnected to the rock-shaft; or it may be connected to the rocking arm in any suitable manner, so that when the operator places his foot upon the treadle the rocking arm will be lowered and cause the hammer to strike on the face of the anvil.
By pivoting the hammer to the outer end of the rocking arm,so that it may turn longitudinally thereon, and providing the-clamping-bolt to secure the hammer at any desired longitudinal inclination, the hammer will be caused to strike upon the anvil at any desired angle, according to the various requirements of the articles that are being forged.
In order to adapt the oliver for use in shearing or cutting metallic plates or bars, we pro vide the dies which are illustrated in Fig. 4, and are adapted to be secured to the anvil and the hammer in lieu of the dies 0 and W.
The spring M has one or more coils or convolutions between the point of attachment to the cross-barH and the rock-shaft K, so that as the hammer is operated said coils will be wound up by the downward movement of the hammer, imparted through the treadle, and automatically unwound to raise the hammer and treadle. The cross-bar H is raised or ele vated some distance above the rock-shaft K and the'hammer, so that the action of the spring M serves to suspend, balance, or poise the hammer for the downward stroke.
Having thus described our invention, we claim 1. In an oliver, the rock-arm L, combined with the hammer adjustable on the arm in an bolt extending through the curved slot and are of a circle, for the purpose set forth. secured to the hammer, for the purpose set 2.
