RADIAL CAR-TRUCK.
SPECIFICATION forming part of Letters Patent No. 555,857, dated March 3, 1896. Application filed January 4, 1894. Serial No. 495,660. (No model.)
To @ZZ whom it may concern:
Be it known that l', JOHN H. GRAHAM, of Boston, in the county of Suffolk, State of Massachusetts,have invented certain new and useful Improvements in Radial Car-Trucks, of which the following is a description suf iciently full, clear, and exact to enable any person skilled in the art or science to which said Ainvention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this speciication, in which- Figure 1 is a top plan view of my improved car-truck; Fig. 2, a side elevation of the same; Fig. 3, a side elevation, partly in section, of the tension mechanismf,` and Fig. a, a vertical transverse section, enlarged, showing the king-bolt castings.
Like letters and figures of reference indiw cate corresponding parts in the different igures of the drawings.
My invention relates especially to a radial car-truck designed particularly for use with electrically-propelled street-cars; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more ef- 'ective device of this character Athan is now in ordinary use.
The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the body of the car and B the truck-frame.' These frames consist of a metallic bai` which is bolted into grooves l) of the spring-supported pedestals C.
.Each frame B is mounted on a single axle,`
only one set of wheels being employed, although two or more sets may be used if desired. Centrally over each pedestal C and on top of the frame-bar B a casting d is bolted, in which friction-rollf is journaled. The carbody A rests on said rolls:
The main portions of the frames are rectangular, but their inner side bars g project At the apex of each frame-bar g a goose-neck casting h is bolted, from which a lug /z promounted on thearch-bars vertically above the axles j, said casting comprising two members o t. `.(Shown in Fig. 4.) The member fr is provided with a central opening s for the king-bolt and with two slots fr, which respectively stride the arch-bars 7c. The member t is secured to the bottom of the car and is provided with a king-bolt w, which enters the opening s, and with an annular lug it, 'which enters an annular socket y in the companion member.' On the bottom of the car-body A (see Fig. 3) an angle-iron l5 is bolted..` Arod 1G passes through the pendent ends of said angle-iron. Fitted to slide on said rod is a block 17.` The outer ends of the goose-neck castings h are slotted longitudinally at 1'8 and work on pins 19 passing through theblock A17. Said block is tensioned against longitudinal movement on the bar 1U by springs 20.
In the use of my improvement the trucks as they pass around the curve of the track act independently, their castings h forcing the block 17 in corresponding direction, the springs 2'0 forcing said castings into alignment again in a manner which will be readily understood without a more explicit description. `The block 17, supporting the castings 7L, prevents the truck-frames from tilting or rocking on the axles, said block being connected with the car-body. Said body being mounted by a king-bolt on the truek-frame permitsfree radial movement of said frames. The frictioirwheels f relieve this movement.
The trucks as thus constructed are exceedingly simple and light, while having all necessary rigidity or strength.
It is not deemed essential to illustrate the motor, as its operation in driving the axles is well known. It will be understood that this form of truck-frame supported in manner deseribed enables a single pair of Wheels to be employed Where ordinarily at least two sets of Wheels are necessary to support the truck.
Having thus explained my invention, what.
I claim isl. The frames, B, provided with the slotted 4. The truck-frame, B, having,` the offset side, g; the casting, 7L, secured thereto and provided With the slot, 1S; the oar-body and spring-tensioned sliding block thereon and a pivot-pin passing through said Casting-slot into said block.
5. The Combination With the ear-body of a rod, 1G, supported thereon; a spring-cushioned block fitted to slide on said rod and two truck-frames pivotallyeonneeted to opposite sides of said block.
JOHN H. GRAHAM.
