ALBERT KEL EY, or nononnsrnn, -v msseennsnr'rs;

RAILWAY-cert TRUCK.

Application filed September To all whom it may concern: 1

Be it known that I, ALBERT J. KELLEY, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State'of Massachusetts, have invented'certain new and useful Improvements in Railway-Car Trucks; and I'do declare the fol I lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the'same.

My invention relates to improvements in railwaycar trucks, and has for its object to provide a truck of novel form in which the weight of the car body is supported at four distinct points around the king-pin or pivot' of the truck, the object of this arrangement being to prevent undesirable vers tical oscillation of the trucks which prevents wearing away the rail ends at the joints, eliminates depression of the road-"S bed at the rail joints,' decreases wear on switches and crossovers, lessens the liability for the rails to become uneven, insures a better easier riding" car, tends to strengthen the construction of the car and truck, is less expensive and more simple than present car trucks, and increases safety of the car by having a four-point support instead of one.

lVith the foregoing in view, the invention resides in the novel subject matter hereinQ after described and claimed, the description being supplemented by the accompanying drawings.

Figure l is a side elevation of a portion of a car embodying my improved trucks.

' Figure 2 is a top plan view of one of the trucks.

Figure 3 is an end elevation. Figure 4c is an enlarged detail vertical section through one of the four yielding supframe adapted for COHDGCtlOII with a car' ports.

Figure 5 is a horizontal section on line 5-5 of Fig. 4. I

Figure 6 is a bottom plan view of a portion of the car body.

In the construction shown, the improved truck includes a pair of suitably constructed side Frames 1 connected by a bolster 2 adapted to be engaged by a king-pin 3, by

means of which a pivotal connection is es- 7; 1922'. sem No.586,715.

i tablished between the truck and the car body 4:; There is no weight supported immediately adjacent the pivot pin 3 but all weight is distributed'at the four corners of the truck. In the preferred form of construction; the ends of the side frames 1 are provided with integ guide cylinders 5 which are provided with integral bottoms 6 and removable top plates 7. These'plates have non-circular openings through which vertical pIungersS pass nonrotatably, thelower ends 9 of said plungers' however being of circular form to slide freely within the cylinders 5. against the action otcoiled springs 10 located in said cylinders to yieldably supportthe plungers. The upper ends of the plungers 8 are provided with 'approprlate anti-friction rollers "11 upon which four tracks 12 carried by the car body 4, concentriewith the pivot 3, are supported, This arrangement permits the car truck to turn freely in rounding curves, yet the body is ,at-all times supported at four points which although allowin all necessary vertical movement of the truck, prevents excessive movement and consequently has the advantages above enumer ated. It will be understood that the plungers 8 are so held that their rollers 11 have their axes disposed radially with respect to the pivot 3, whereby they may freely roll upon the tracks 12, it being to maintain this relation, that the plunQ'ers pass non-rotatably through the cover'plate 7. 7

Excellent results may be obtained from the details disclosed and they are therefore preferably followed. but within the scope of the invention as claimed, numerous minor changes may be made. i

I claim:

1. A car truck comprising a wheeled body to yieldably support thelatter at four points; I

2. A car truck comprising a wheeled frame adapted for connection by a central al verticall disoosed- & L

pivot to a car body, the four corners of said tracks on a car body and coiled springs in frame having integral vertical cylinders prothe cylinders supporting said plungors vided with bottom and top plates, the latter yieldahly. 10 having non-circular openings, plungers hav- In testimony whei'eol I have hereunto ing non-circular portions, passing through afiixed my signature. said non-circular openings, the upper ends of said plungers being adapted to engage ALBERT J. KELLEY.
