Sncc ification of Letters Patent.

I Patented-April, 1912 A Application filed June 9, 1911. Serial l lo, 682,190.

To all whom it may concern: Be it known that 1, WILLI M L'AUSTIN, a citizen, of the United States, residing in Philadel hia, Pennsylvanis, have invented certain mprovements in Car-Trucks, of which the following is aspecification.

This invention relates to certain impro've merits in the construction ofcer trucks, par- Ill ticulai'l those in which an electric motor is" 3 carried by the truck.

One object of the in's ention is tomake com mratively light truck, in which the side frames will he rigidly connected to the transoms. I w

A further object of the invention is to de sign the truck in such a manner that the motor supporting frame will'loe carried by the projecting ends of the truck.

In the accompanying drawings :Figure l, is a plan view of my improved car truck; Fig. 2, is a sideview; Fig." 3, is a, transverse sectional view on the line 3- 3, Fig. l; and Fig. 4, is a perspective view of one of the brace plates connecting the side frames to the trensoins. v

A A' are the side fremes of the truck connected together loy transoms B B. These transoins are COIH'IGCtGd tOgGthGI at their outer edges by U-shaped plates B.

-C--C are the-axles on which are mountedthe Wheels 0 and these axles are adapted to boxes 1) mounted between the. pedestals AA. of the side frames.

E are brace plates, which rigidly connect the side frames of the transoms; .These plates are each mode of asingle piece, and are beveled at each end. .The plates extend under the longitudinal upper bar A of each side frame and are connected thereto by engle bars 6. These angle bars are secured-by l'iolts to the bars A. and to the plate Fl Two ofthe bolts extend through the upper flange of the transom. Thus each plate has [an extended connection with the side frames and is rigidly connectedby a series of-bolts to the upper flange of each transom, as clearly illustrated in Fig. '1. Eachplate IS I cut away to form a recess a to allow for the reception of the bolster F,"which is carried by springs F", moiinted on a spring plank f suspended by links from the transoms in the ordinary manner. Each plate E is turned down at the inner end of the recess e to form an abutment e to receive the end the present instance, on the outs to the other but the innerhesni plates secured to each" si adder at the w i extendm :nndsr the trnnsoi of he rams-anti extending thrust of the holster. This is one of the es;

top bar and there is but e'single brace A, of the diagonal type, extending under the-"6G ll-shaped plate B; connecting the transoms to the inner stance. P are the motors, which aremonnted es the axles, and the inner ends of these momm es are supported by the'frame M, as 'cleerly illustrated in Figs. 1 and 2. I w

The outer pedestals A are triangular in shape'and have extensions/l, at their lowe outer ends and pivoted to these ext-ens 'n' ere rods m, which extend thronghperi tions in the ends of. the mot-orsnpportmg frames M. There is a. heavy spring',m= mounted on the rod between the extension k s of the pedestal and the supporting teen-le also a light spring m hetween'thenst in on the end of the rod and the supportingifrnrn Mounted between. the plates oi theipedes tale, in the present instance, are gihs "i, which are detaohably secured ,inaplece .Thetw pedestals for each box-(ere, connected getlier at their lower ends hiy bsrs g. In th present instance, the end'pedestal' freines A heave open centers anchmounted in-these openings are springs n, which ersloce between the side frames and the eqnelizm beams N--N. The equalizing. sin

frame, extends straight-across cl fli ts and extends nnderthe-tran ns, tes cles! illustrated in Fig.2.

I lay no cl'eim construction, namely, bars extending above pedestal plate, in the presentinf Y es, of;

forming pedestals, the inner per end, w

plates forming the pedestal thereto et a pointbelow t bur." Nor do 1 claim the detach cured to thepedestnls, as theab tion is set forth andclai-n'ied application filed by Wsne; Hohson o p 22nd, 1911, under Seriel;- h 'of"622,68 or 1 do I lay claim to a short angle hrsc ex tending under the U-shaped member of the transom and attached to the pedestals at a point below the top bar, as this is set forth and claimed 'in a separate application filed by Benjamin It. Van Kirk on June 9th,1911 under Serial No. 632,151.

By the above construction, it will be seen that I am enabled to make a very light and substantial truck, especially adapted for trolley and inter-urban work; in which the side frames are comparatively light and in which the chafing of the bolster is taken by a part of each plate which connects the transoms to the side frames. I also provide for. the proper support of the overhanging portion of the motors.

I claim:

The combination in a truck, of side frames; transoms extending from one side frame to the other; with brace plates connecting the side frames to the transoms; each plate being made of a single piece and recessed to receive the bolster; the plate being bent at the inner end of the recess to form an abutment to receive the end thrust of the bolster.

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