EQUALIZINQMEEIANVS FOR, LOCOMOTlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 545,628, dated September 8, 1895.

Application filed October 6, 1894. Serial No. 525,130. (No model.)

keep the engine from causing the flanges of,

the forward driving-wheel tire, as also the truck-flanges, to become out by the shifting weight thereof; and it has, primarily, for its object to providev a simple arrangement of equalizing devices which can be easily and quickly anjusted, whereby to cause the engine-truck to guide the engine from one side to the other, as may become necessary.

With other objects in view, which herein after will appear, the invention consists in such novel features of construction and pe culiar combination of parts, as will be first described in detail, and then be pointed out in the claims, reference being had to the accompanying drawings, in which Figure l is a side elevationof a portion of a locomotive-engine with. my improvement applied, parts being broken away to the more clearly illustrate the several parts. Fig. 2 is an elevation, partly in section, illustrating the relation of the front drivers, the enginebody, and the equalizing devices. Fig.3 is a perspective view of the longitudinal equalizing-beam. Fig. 4 is a similar view of the transverse equalizing-bar, and Fig. 5 illus-. trates in detail the several pivot and connecting pins hereinafter referled to.

the engine-body, B the forward driving In the accompanying drawings, A indicates bearing portion at the lower end, which also passes through an apertured ear d on the cradle of the engine-truck, it being held secured by a pin, F, whereby it is made rigid with the cradle of the engine-truck and held from swinging itself at such end,but capable of adjusting the cradle when moved for such purpose. The opposite end of the beam D is provided with a transverse aperture 01*, which end is fitted between the apertured ears G G of a transverse equalizing-bar or inverted yoke-frame G, and is pivotally connected thereto by the cross-pin g. Such connection, while allowing for an up-and-down motion, holds the beam D from side play. The up per portion of the frame G terminates in horizontal ears g'., which are apertured, as at g through which pass hangers H H, the heads of which pass through elongated openings 1) b in the forward driving-springs, such heads having apertures h, through which pass the gibs or keys h, the hangers being held secured by the nuts I I, as shown.

From the foregoing, taken'in connection with the accompanying drawings, it is thought the complete structure and operation of my invention will be readily apparent. In the practical application, should the engine, when running, cause the flange on the right forward driving-wheel to cut away, the nuts I I on the right-side end of the bar G would be screwed up to raise such side until the ears G G and the back end of the longitudinal bar are central with the engine, the same operation being performed on the opposite side of the bar G should the flange 0n the left side of the wheel be cut.

I claim, and desire to secure by Letters Patout, is-

1. The combination with the engine truck cradle, the engine saddle, and the front drive springs, of a longitudinal bar pivoted about the center of its length to the engine saddle and having its front end secured to thetruck cradle, a transverse bar having apertures in its ends and a projection on its lower surface to which the rear end of the longitudinal bar is pivoted, and threaded hangers secured to the springs passing down through the aperspaced lugs on its under side at the middle tures of the said transverse bar and provided and between which the rear end of the longiwith nuts thereon, substantially as described. tudinal bar is pivoted, hangers secured to the I 5 2. The combination with the engine truck springs and having their ends threaded and 5 cradle, the engine saddle, and the front drive projecting through the openings of the transsprings, of a longitudinal bar pivoted at about Verse bar, and nuts on the. said hangers, subits middle to the engine saddle and provided stantially as described. at its front end with a vertical aperture and at its rear end with a transverse aperture, a JOHN E. HUGHES. 1o bolt securing the front end of the said bar to Witnesses:

the truck cradle, a transverse bar having ver- O. K. WHEELER,

tical apertures in its ends and provided with ALEX LAZARUS.
