Description
i UNITED STATES 1 PATENT Granice.,
CHARLES M. GIDDINGS, OF MASSILLON, OHIO.
REVERSI NG-GER.
SPECIPICATION forming part of Letters Patent No. 315,762, dated April 14, 1885.
Application filed December G, 1834.
i To aZZ whom it may concrn:
Be it known that I, CHARLES M. GrDDINGs, of Massillon, in the county of Stark and State of Ohio, have invented certain new and useful Improveinents in Reversing-Gears; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aecornpanying drawings, which form a part of this specification, and in which- Figure l is a side view of my improved reversing-gear. Fig. 2 is a front view of the same. Fig. 3 is a Vertical sectional view taken axial with the shaft; and Figs. 4, 5, and G are detail views of the several parts of the gear.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to that class of reversing-gears in which the valve-Operating eccentric disk slides with a diametrical slot upon the shaft; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.
In the accompanying drawings, the letter' A indicates a disk which has a diametrical slot, B, with which it slides upon the shaft O, and which disk has the ring to which the valverod Operating connecting-rod is seeured, sliding around its periphery. The face of this disk has narrow bearing-ribs D, and a dovetailed diametrical rib, E, parallel with the slot, which rib fits in a eorresponding groove, F, in the face of a disk, G, keyed or otherwise secured upon the shaft by the side of the shifting-disk, and the narrow bearingaibs of the shiftingdisk A bear against the face of the ri gi d disk G. A curved arm, H, is pivoted at its lower end in one end of a recess, I, in the face of the shifting-disk, which said recess is parallel with the slot, and the other end of the arm is pivoted to one arm of a hell-Crank, J, which has its fulerum in a recess, K, in the face of the rigid disk. A rod, L, is pivoted to the other arm of the hell-Crank, and the other end of the said rod is pivoted to a disk or colla-r, M, sliding upon the shaft, the rod passing through a perforation, N, in the rigid disk. The sliding collar M has a peripheral groove,
(No model) O, V-shaped in section, and a ring, P, having a rib, Q, corresponding in Shape to the groove, is secured around the collar, the said ring con sisting of two halves, having perforated lugs R at their ends, which are secured by means of sorews S, which serve to tighten the ring upon the collar when either the rib or the groove becomes worn. The ring has two dia metrically-opposite lugs or pins, T T, and the ends U of a bifurcated bellecrank, V, are pivoted upon these lugs, the said ends having means for tightening their bearings upon the lugs. The hell-crank is pivoted upon the frame of the engine or upon the boiler, or any other suitable place, and a connecting'rod, XV, is pivoted to the other arni of the bell-crank, and has its other end screw-threaded and fittin g into a common right and left hand thread ed sleeve, X, into the other end of which fits the screw-threaded end of a short rod, Y, the said screw-threaded ends of the rods being seeured in the sleeve by means of jainnuts Z Z. The end of the short screw-threaded rod is pivoted to a hand-lever, A', which is pivoted in the center of a grad uated notched segment, B', which segment is engaged by a spring-lock, O', upon the lever, serving to adjust the said lever in any desired angle. It will now be seen that as the lever is tilted the connecting-rod will rock the hell-Crank, which again will siide'the sleeve to one side or another, and the said sleeve or collar will tilt the hell-Crank in the rigid disk by means of its connecting-rod, which hell-Crank again will either draw or push the Curved arm and either' slide the shiftingdisk to one side or the other, thus serving to regulate the stroke of the valve, and eonsequently the speed of the engine, and at the same time serving to reverse the engine by shifting the disk from one position to its diametrically-opposite position.
Having thus described m y invention, I claim and desire to secure by Letters Patent of the United States- In a reversing-gear, the combination of the shifting-disk having the diametrical slot, the diametrieal dovetailed rib, and. the recess parallel with the slot, the rigid disk having the dovetailed groove in its face with means for taking up wear, and having the recess and IOO IVO
ing the V-shaped rib and the diametrioaily-v opposite studs, the bifurcated hell-Crank having its ends pivoted upon the said studs, the
conneoting-rod pivoted to the other arm of 1 the belll-crank iand having .means for tdjustingl its 1ength,gthe hand-level' having' the springloek, and the notehed segment, as and for the purpose shown and set forth.
In testimony that I claim the foregoing as my own I have hereuntoaffi'xed my signature in presenee of two Witnesses.
CHARLES M. GIDDINGS.
