MECHANISM FOR CONVERTING ROTARY INTO OSCILLATING MOTION.
SPECIFICATION forming part of Letters Patent No. 252,768, dated January 24, 1882.
Application filed August 5, 1881.
To all whom it may concern:
Be it known that I, JULIUS HORNIG, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Mechanisms for Converting Rotary into Oscillating Motion, of which the following is a full, clear, and exact specitica-' tion.
Figure l is a side elevation of the original machine. Fig. 2 is a side elevation of my improvement. Fig. 3 is a plan view of the same. Fig. 4 is the same view as Fig. 3, but showing a different arrangement of the eccentric-strap. Fig. 5 is a perspective view of a modification of the improvement. Fig. 6 is a sectional plan view of the same.
Similar letters of reference indicate corresponding parts.
The object of this invention is to improve the construction of the mechanism for converting rotary into oscillating motion for which Letters Patent No. 46,237 were granted to me February 7, 1865, and Reiss'ucd Letters Patent No. 3,717 were granted to me November 9, 1869, in such a manner as to facilitate and cheapen the repairing of the said mechanism should it be broken by being overtaxed.
The invention consists in the combination, with the rotating eccentric and the oscillating lever, of the roller or segment and the breakpin, whereby the breaking of the said lever will be prevented should its movement be obstructed; and, also, in the combination,with the eccentric-strap and the break-pin, of the arm having a slot or clearance-space to receive the said pin, whereby the said arm will be kept from being broken should the oscillating lever be obstructed, as will be hereinafter fully described.
I will describe the improvement as applied to a shear, but do not limit myself to that use, as it can be applied with equal advantage to various other mechanisms.
A represents the frame of the machine, in bearings in the upper part of which revolves the shalt B. The shaft B is connected by gearwheels 0 D with the driving-shaft E, which revolves in hearings in the lower part of the frame A, and to which motion is given froma steam-engine or other suitable power.
To the shaft B is attached aneccentric or (No model.)
cam wheel, F, by which motion is'given to the oscillating lever G. The leverG is pivoted to the lower part of the frame A, and in the drawings is represented as having a shear-blade, H, attached to it, but which can be connected with any suitable machinery that is required to be operated by an oscillating movement. In the original mechanism the leverG rested direcly against the eccentric F, so that if the machine was over-taxed the lever G had to break and be replaced by a new one. In my improvement the upper end of the lever G is so constructed as to, leave a clearance-space between the said lever and eccentric, so that the eccentric can revolve without touching the lever. In this case the face of the eccentric F rests against the face of a roller, I, or segment I, connected with the upper end of the lever G. The upper end of the lever G is slotted to receive the hub of the rollerI or the web of the segment I. In case a roller I be used, it revolves upon a pin, J, attached to the lever G. In case a segment I be used, it is supported by the pin J, and is held from revolving by a small second pin, K, passing through it and through the said lever, as shown in Fig. 5.
The pin J is made of such a size and strength as to be the weakest point of the mechanism, so that should the mechanism be taxed beyond its capacity the said pin will break, and thus prevent the lever G from being broken.
Additional security can be had by making the shell of the roller I or segment 1 sufficiently light to be crushed should the lever G be obstructed. With this construction the lever G is pushed forward to make its stroke by the pressure of the eccentric F, against the roller I or segment I, and is drawn back, after making its stroke, by the eccentric-strap L, which passes around the eccentric F and has a lug or 'arm, M, formed upon or attached to it. The arm M is connected with the pin J by. a loop-clevis or U-shaped bar, N, which passes around the said pin, and is secured to the arm M by a pin or bolt, so as to leave a slot or clearance-space, 0, between the end of the arm M and the pin J, to allow the said arm to move forward withoutbeing broken should the forward movement of the lever G be obstructed. If desired,the armM andloop N can be made in one piece and slotted to receive the pin J.
Having thus fully described my invention, I oscillating motion, the combination, with the claim as new and desire to secure by Letters eccentric-strap L and the break-pin J, of the Patent arm M N, having a slot or clearance-space, 0, I5
