VILLIAM P. HENSZEY, OF PHILADELPHIA, PENNSYLVANIA.

ELECTRIC-LOCOMOTIVE TRUCK.

SPECIFICATION forming part of Letters Patent No. 562,607, dated J' une 23, 1896.

Application filed October 4,1895. Serial No. 564,643. (No model.)

T0 LZZ whom t may concern.:

Be it known that I, VILLIAM P. HENSZEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements `in Electric Locomotive Trucks, of which the following is a speciiication.

My invention relates particularly to the trucks of electric locomotives, and the main object of my invention is to so construct the truck that it will be perfectly rigid and capable of withstanding the strains to which a truck of an electric locomotive is subjected.'

My invention relates, further, to the special arrangement of the equalizing-bars, the construction of the boxes, and the arrangement of the bolster; but itwill be understood that my improvements can be applied to any cartrucks.

Referringwto the accompanying drawings, Figure l is a side view of my improved truck. Fig. 2 is aplan view. Fig. 3 is a longitudinal section on the line 3 3, Fig. 2. Fig. 4 is a longitudinal section on the line 4 4, Fig. 2. Fig. 5 is a longitudinal sectional view through the axle-box of the truck. Fig. Gis a transverse sectional view; and Fig. 7 is a section on the line 7 7, Fig. l.

A A are the sideii'rames of the truck, consisting of the upper beam d, the side bars a', forming the pedestal, and the lower bar c2, extending from one pedestal to the other. The side bars d a of the pedestal are secured to the upper beam by bolts d3 and at the lower ends are held together by a bolt CL4. Adapted to the pedestals are the journal-boxes C C for the axles of the truck, as shown by dotted lines. B is a plate extending over the upper surface of the truck from one side frame to the other. This plate is made in one piece The plate is securely bolted to the side frames and to the channel-bars A', which extend below the plate from one side frame to the other. The plate B has openings h h' for the center plate and side bearings. By this arrangement the truck-frame is made perfectly rigid and will not work loose by the action of the motors carried by the trucks.

Suspended by links d from bearings d on the plate B is a swinging spring-beam D, carrying the elliptic springs D', which in turn lcarry the bolster E, mounted directly under `the plate B of the truck-frame- This bolster `consists of a channel-beam e and a brace-plate c', suitably tied together, in the present instance by the bolts` which secure the truck center E to the bolster.

At each end of the bolster are the side bearing-blocks E2. The truck center and side bearing-blocks, as will be noticed on reference to Figs. 2 and 4, extend through the openings inthe plate B and these openings are of sufficient size to allow for the free movements of the bolster. By this arrangement the bolster and spring-plate are placed in position from below, so that the rigidity of the truck is not affected by the bolster.

At each side of each side frame A is an` two equalizing-bars, 'one at each side of the frame, I do not weaken the frame in any mana ner and provide a much better support for the truck.

The boxes C C (shown clearly in Figs. 5 and 6) are constructed in a manner different from those usually employed in trucks of this character. 'The bearing-block or brass in an ordinary box is loose in the box, so that the axle will have a certain amount of freedom to seat itself; but I fit the brass or bearing-block c snugly in the box, as indicated in Fig. 6; in fact, I make it a tight lit, so as to prevent lost motion and extend the brass down to or past the center of the axle and thus prevent the axle from jam ming or moving laterally in the box. I form the usual chamber c under the journal of the axle for the lubricating-oil and waste. Each box snugly iits its pedestal, so

that the truck is perfectly rigid in all its parts.

I claim as my inventionl. The combination in a car-truck, of the side frames A A, the top plate B extending from one side frame to the other, openings in the top plate, with a bolster having a center IOO plate and side bearing blocks extending'. through openings kin the top plate, substantially as deseribed.

2. The combination in a truck, of the side frames A A having a pedestal for the axlebox, the bars A extending from one side frame to the other and inelosing the bolster, a top plate extending from one side frame to the other and secured to the side frames and the; bars A', openings in said plate for the passage of the center plate, substantially as set forth.

3. The combination in a ear-truck, of they side frames Carrying the pedestals for the axleboxes, the channel-bars A extending from one side of the frame to the other, a bolster mounted within the space between said bars, a top plate B extending from one side frame to the other and'seeured 'thereto and to the ohannel-bars, a spring-plate hung 'from the., frame thus vformed and rcarrying the bolster,

openings in the top plate through which the center bearing-plate and side bearing-blocks extend, substantially as described.

4. The Combination in a oar-truck, of the frame consisting of the side frames A A and the top plate B extending from one side frame to the other, axle-boxes snugly iittin g the pedestals of said side frames, eaeh box having a bearing snugly iitted thereto, and extending down on eaeh side of the axle forming side bearings as well as a top bearing for the axle, substantially as deseribed.

In testimony whereof I have signed my naine to this speeiiieation in the presence of two subscribing witnesses.
