CAR-TRUCK.

SPECIFICATION forming part Of Letters Patent No. 671,844, dated April 9, 1901.

Application filed February 8, 1901. Serial No. 46,523. (No model.)

T all whom, it nfl/wy concern,.-

Beit known that I, CHARLES F.WEs'rLAKE, a citizen of the United States, residing at Granite City, county of Madison, State of Illinois, have invented a certain new and useful Improvement in Oar-Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, 1o reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a top plan view of my improved car-truck. Fig. 2 is a side elevational view, partly in section. Fig. 3 is an end elevational view, partly in section, of my improved cartruck; and Fig. 4 is a vertical sectional view on line 4 4, Fig. l.

This invention relates to a new and useful 2o improvement in car-trucks, being designed particularly for use in connection with tenders for locomotives, though it is obvious that with slight modiications the truck can be adapted to freight and other cars. z5 The object of the invention is to construct a truck-frame which is simple, being composed of few pieces, and which is also extremely strong.

With this object in view the invention con'- sists of the construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims.

In the drawings, A indicates the side frame 3 5 of the truck, which is preferably made up of a casting, the upper edge of said side frame having an inwardly-extending flange on, extending throughout the length of said side frame.

This side frame is made deepest at its middle" 4o portion, the ends being relatively shallow to accommodate the journal-boxes. The top ange a is integral with vertical end flanges a', to which latter are joined the bottom flanges a2.

a3 indicates strengthening-webs integral with the iianges a and a* and the main web of the side frame, said strengthening-webs 0,3 being preferably located above the journalboxes to strengthen the casting at this point.

5o The anges are also provided with suitable openings to receive the column-bolts by which the journal-boxes are'secured in position.

a4 indicates fins or webs preferably integral with the top flange and main web of the side frame, said fins terminating above the bot-tom flange 0Lv2 to enable the proper manipulation of rivets, which secure the tie-bar in position. The main web of the side frame may be lightcned by removing material therefrom at appropriate places.

B indicates transoms, which are shown in the drawings as being Z-shaped,with their top iianges presented outwardly. These transoms are preferably cast, and the top flanges b at the ends thereof diverge or widen to some considerable extent in order to accommodate a row of attaching-rivets passing therethrough and through the top flange a of the side frame. The vertical webs of the transoms are attached to the fins a4 by suitable rivets, 7o whereby a very rigid connection is made between the transoms and side framing. These transoms are preferably made shallow at their middle portions and deepest at their ends and are so constructed as to provide guiding-ribs b for the bolster C. This bolster C is shown as being made in one piece and provided with suitable spring-seats for the accommodation of elliptic springs D, while spring-seats E are riveted to the lower edges of the transoms 8o for supporting said springs. These springseats E are strengthened by webs and flanges appropriately placed and disposed, as shown.

` While I have described a construction having a slat spring-seat, it is obvious that a stirrup could be employed in connection with said bolster should it be desired to use my improved truck-frame in connection with the well-known type of swing motion bolster. Furthermore, instead of supporting the bol- 9o ster on springs the side framing could be provided with pedestal-jaws for the reception of the journal-boxes, above which the springs could be used, as is well understood; also,

while I have described my improved side frame and transoms as being made up of castings, preferably of steel, it will be understood that the same could be formed of malleable iron, or sheet metal could be used by being pressed or bent into shape. However, Ioo

I prefer to use east-steel, asI the i-u-tegrality of parts obviates the necessity for so many lrivets as are usually required in pressed-steel trucks.

I am aware that minor changes in the construction., arrangement, and combination of the several parts'of my truck can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a car-truck, the combination with the side frames, of transoms having their top flanges presented outwardly, said lianges being widened at the ends of the transoms and attached to inwardly-extending flanges at or near the upper edges of said side frames, substantially as described.

2. In a car-truck, the combination with a side frame provided with vertical iins and an inwardly-extending top ange, of transoms having top flanges presented' outwardly, said flanges of said transoms being widened at the ends and riveted to the top liange of the side frame, the vertical webs of the transoms being riveted to the inwardly-extending fins of the side frame, substantially as described?.

3. In a car-truck, the combination with a sidefranle made deepest at itsk middle portion,

provid-ed Witlran inwardly-extending marginal angepf strengthening-webs;between said flanges above the journal-boxes, inwardlyextending fins a4, transoms whose top flanges are widened at their ends. and riveted to the top flange of the side frame, the vertical web of the transoms being riveted to said fins, and

a bolster supported between said transoms, substantially as described.

4. In a car-truck, the combination with a side frame made deepest at its middle portion v.and provided with inwardly-extending marginal Iianges, of Z-shaped transoms having their top flanges presented outwardly and widened at the ends, where they arer'secured to the side frame by suitable rivets, the bottom flanges of said transom-s extending i-n` wardly and receding to the main web of the transoms near the ends thereof, and removable spring-seats arranged between theftran'- soms and shaped to accommodate said inwardly-extending bottom flanges, substantially as described.

In testimony whereof I hereunto affix my signature, inl the presence of two Witnesses, this 6th day of February, 1901.

CHARLES -T. WESTLAKE.
