CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 479,237, dated July 19, 1892.

Application filed March 11, 1892. Serial No. 424,564. (No model.)

To a/ZZ whom t may concern,.-

Beit known that I, JOHN E. ANGER, of Green Island, in the county of Albany and State of New York, have invented certain new and useful Improvements in Car-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference beinghad to the accompanying drawings, which form part of this specication.

My invention relates to improvements in car-trucks which are especially adapted for electric-motor cars; and it consists in the truck-frame, combined with pivoted equalizizing-bars upon which the body of the car rests, and a suitable spring placed between the inner ends of the bars and the car-body, as will be more fully described hereinafter.

The object of my invention is to support the body of the car upon pivoted equalizingbars, and thus prevent the car from oscillating, which is so common to car-trucks and so very objectionable.

In the accompanying drawings, Figure l is a side elevation of a truck which embodies my invention complete. Fig. 2 is a detached side elevation of the bottom or pedestal stay, one end thereof being shown in section. Fig. 3 is a detached side view of one of the cornercastings. Fig. 4 is a detached plan view of the same.

A represents the wheels and B the bars of the truck-frame, which latter are curved upward so as to pass over the journal-box casting or pedestals b, as shown, and which are secured to the bars B. There are preferably two of these bars B at each side of the car, and may either be placed together or separated, as desired. Pivoted between their ends in the upper recessed and rounded ends of the pedestals b are the equalizing-bars D, which are prevented from moving endwise by means of the pivotal bolt-s E, which are passed through the pedestals, castings, or jaws l), and the bars B and the equalizing-bars D. Two of the equalizing-bars D are used upon each side of the truck, and their outer ends are inclined upward, so as to allow the car-body F to rest directly thereon. The inner ends of these bars D approach eachother, as shown in dotted lines in Fig. 1, and resting upon the inner ends of both is a suitable spring G. I here show the spring G as aleafspring, which has its ends to bear directly against the plates H, applied to the under side of the car-body; but any other form of spring which will answer the same purpose may be used. Passing over the center of the spring G and the inner ends of the bars D is a band I, which has its lower end to play vertically between the bars B,which form the truckframe, and through the top of this band I is passed a set-screw J to take up all wear. Between the outer ends of the bars B and the outer ends of the equalizing-barsD are placed suitable springs L, which serve to assist the equalizing-bars D from sinking at their outer ends; but these springs may be done away with when the equalizing-bars are applied to a short car, as will be readily understood.

Projecting outward between the outer lower corners of the pedestals b are the inclined bars Q, upon which the brushes S are adjustably secured by a means of a sleeve and setscrew T, whereby the brushes can be moved outward and secured in any desired position to bring them nearer to the track as they wear, as will be seen. These inclined bars Q are braced in position and supported at their `outer ends by means of hangers U, extending down from the side bars B. The truck-frame is braced by means of the bottom stays d, which are placed under the lower ends of the pedestals b, between which the axle-boxes slide, as usual. These stays d are provided with recesses e in their upper sides to receive the lower ends 'of the pedestals b, which latter are secured to the pedestals by means of bolts which pass vertically through them. Made in the ends of these stays d are the sockets f, which receive the ian ges of the hollow nuts h. The openings of these nuts are likewise screw-threaded and receive the externally-screw-threaded ends of the stay tubes or rods m. It will be noticed from Fig. 1 that the stay tubes or rods do not quite reach to the stays d and that the nuts h serve to connect the tubes therewith. The object of this construction is to allow the stay-tubes m to drop down clear of the stays d by screwing the nuts h outward upon the tubes, as will be understood, thus avoiding the necessity of removing the stays d from the pedestals when IOO access is desired to an electric motor carried by the truck or for any other purpose.

Placed upon and secured tothe outer ends of the bars B are the castings n, which are provided in their upper faces with recesses p, which receive the springs L, and with the tubesockets q to receive the outer ends of the short inclined tubes r, that have their ends secured in the outer sockets of the bottom stays d by nuts t, similar to the nuts h.

The car-body rests directly upon the outer ends of the equalizing-bars D and is made fast thereto in any suitable manner. The center of the car rests upon the spring G, which is supported by the inner ends of the equalizing-bars,therebyequalizing the weight and keeping the car-body level. The upper ends of the jaws, pedestals, or castings b be ing rounded, the equalizing-bars can rock or turn thereon, so that as their outer ends are depressed their inner ends will rise against the spring G. Any movement at one end of the careects the other end through the equaliz ing-bars, thus causing the center spring to act between the body of the car and the inner ends of the equalizing-bars. This construction causes the outer ends of both the equalizing-bars to move in the same direction at the same time, and thereby overcome the pscilllation of the car and keep it perfectly eve A much longer car can be carried upon a car-truck constructed, as herein shown, with a small wheel-base and as the overhanging weight of the car-body is equalized and carried back and the whole weight of the body brought directly over the axle. For open street-cars equalizing-bars are to be hung under the castings or jaws in any suitable manner, so as to lower the car.

For steam-cars a slight change in construe tion is necessary, but not in principle, especially in short four-wheel cars.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a car-truck, castings b, having curved upper ends, bars B, supported on said cast ings, bars D, adapted to rock on the said curved upper ends of the castings, a guide in which the inner ends of the ba'rs D move vertically, and a spring confined within the said guidethe parts being combined to operate substantially as shown and described.

2. In a car-truck, the castings b, having forked upper ends` vbars B and D, confined within the said forks, springs interposed between the outer ends of the said bars, a guide in which the yinner ends of the bars D move vertically, and a spring secured in the guide, the parts being combined to operate substantially as shown and described.

8. In a car-truck, the castings b, bars B and D, springs interposed between the outer ends of the bars, a guide for the inner ends of the bars D, which move vertically between the bars B, a spring secured in the upper end of the said guide, and a set-screw J, the parts being combined to operate substantially as shown and described.

4. In a truck, a suitable frame, the wheels jou rnaled therein, equalizing bars pivoted` between their ends substantially over the axles and extending inward to substantially the center of the truck, combined with the car-body, which has its ends resting upon the outer ends of the equalizing-bars, and a spring between the center of the body and the inner ends of the said bars, substantially as set forth.

5. In a car truck, forked castings l), arranged over the journal-boxes of the trucks, bottom stays d, secured to the lower ends of said castings and having their adjacent ends bent downward and recessed, screw-threaded nuts fitting the recesses thus formed, and a screw-threaded truss-brace which connects the said stays, substantially as shown and described.

6. In a car-truck, wheels, axles, and axle- 5 boxes, depending castings supported by the latter, a longitudinal bar supported` on the upper end of the castings, castings secured to the ends of said bar, socket portions q, proj ecting from said castings, and a truss-brace secured at its respective ends to the said sockets, substantially as shown and described.

In testimony whereof I afix my signature in presence of two witnesses.
