SPECIFICATION forming part of Letters Patent No. 567,472, dated September 8, 1896.

Application led March 19,1896.

Be it known that I, WILLIAM P. HnNsznY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Trucks, of which the following is a specification.

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

A further object of the invention is to provide for the ready removal of the axles from the truck.

Referring to the accompanying drawings, Figure l is a plan view of my improved locomotive-truck. Fig. 2 is a side view of the same. Fig 3 is a longitudinal section on the line 8 3, Fig l and Fig. 4 is a transverse section on the line 4. 4, Fig. l.

A A are the side frames of the truck, each side frame being composed of two plates a a, secured together and to two distance-pieces 'a' a2 by rivets or bolts, as clearly shown in the drawings. The distance-piece Ct at the top extends the full length of each side frame, while the distance-piece a? is shorter and is used to brace the bottom of the frame midway between the pedestals.

B B are the pedestals for the boxes C. In the present instance the pedestal B is attached rigidly to the frame, being mounted between the two plates ct a, while the pedestal B is pivoted tothe frame at b and secured to the fixed pedestal by a bolt b. By this arrangement the boxes can be readily removed from the truck.

The construction of the pedestals above alluded to forms no part of my invention. It is fully described and claimed in an application filed by George NIestinghoiise, Jr.

On the axle D are the wheels d d, the axle, wheels, and journal-boxes being of the ordinary construction.

Bearing on the top of each box C is an elliptic spring C', the ends of the spring resting against pins c in the frame. I'Ience it will be seen that while the springs have free vertical yielding movement they are inclosed laterally Serial No. 583,910. (No model.)

' between the plates of the frame which protect the other directly below the plate E are chan-v nel-bars E', having their flanges on the inside and forming a box for the bolster F. The

upper plate E is bolted to the upper flange l of each channel-bar E', as shown in Fig. l, and the channel-bars are secured to each side frame A by angle-plates ecs and a bracket e4. These brackets are riveted or bolted to the lower flange of each channel-bar and to the frame, the bolts passing through the two plates a c and lower distance-piece a2, as shown in Fig. 4. By this construction I provide a box for the bolster and its springs, the box having an open bottom, so thatready access may be had to the bolster and springs from underneath.

The arrangement ofthe parts as above described makes a very rigid truck, fully capable of withstanding the strains to which an electric-locomotive truck is subjected, and as the parts are connected at the center, ample room is aiiordedfor the reception of the motor mechanism, brake mechanism, and other parts carried by the trucks.

The upper plate E has a central opening e', through which extends the center plate f, mounted on the bolster F, and side openings c2, through which extend the side bearing blocks f', also mounted onthe bolster. The bolster F consists of a top plate f2 and a braceplate f3. A swinging spring-plate G is suspended by links g g from studs g on each channel bar E. rlhe plate carries the elliptic springs II Il, one at each side. These springs support the bolster F, as clearly shown in Fig. 4. Openings are made in the side frames Ato allow for the free movement of the springs and also for the ready removal of the bolster when necessary.

The cross-frame or box composed of the upper plate E and channel-bars E is stiffened by the angle-bars E2, mounted on the IOO plate E at the center, so as to form an additional bearing for' the center plate.

I claim as my inventionl. The combination in a car-truck, of the side frames AA, each made of two platesv estals and springs mounted between the plates of each side frame and resting` upon the boxes, substantially as described.

8. The combination in a car-truck, of the cross-frame, the two side frames each composed of two plates, distance-pieces between the plates, fixed and movable pedestal sections mounted in the side frames, said frames being cut out to receive the pedestals, elliptic springs mounted on the journ al-boxes between Y the plates,y bearing-pins against which the springs rest, the parts beingV so constructed that when the movable pedestal sections are withdrawn the boxes and their springscan be detached from the truck, substantially as described.

4. The combination in a car-truck, of the side frames, each composed of two plates, the

cross-frame composed of a top plate and side channel-bars, said top plate having extensions secured to the side frames, a bracket securing the lower lan-ges of the channel-bars to the sideA frames, a spring-plate suspended from said cross-frame, a bolster within the frame, and springs mounted between the bolster and spring-plate, substantially as described.

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

WILLIAM P. HENSZEY.
