HERBERT H. I-IEVVITT, OF BUFFALO, NEV YORK.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 571,524, dated November 17, 1896.

Application filed OGObel 5, 1896. Serial No. 607,938. (No model.)

To all whom it may concern,.-

Be it known that I, HERBERT I-I. I-IEWITT, a citizcnof the United States, and a resident of the city of Buffalo, in the county of Erie, in the State of New York, have invented certain new and useful Improvements in Oar- Trucks, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The present invention consists, primarily, in providing a car-truck, the side frames of which are furnished with bifurcated ends forming open-ended spaces, with pedestals that are formed each with twovertical jaws connected bya top plate, but open at the bottom for receiving the oil-box (and springs if desired.)

A further `feature of the invention consists in forming the pedestal with a spring-cap in piece with the side jaws and Vtop of the pedestal. j

The invention further consists in various features of improvement hereinafter set forth, illustrated in the accompanying drawings, and particularly defined in the several claims at the end of this specification.

Figure 1 is a view in side elevation of the side frame. Fig. 2 is aview in side elevation of the side frame with the pedestals in place. Fig. 3 is a plan viewof the side frame, showing the portions of the bolster attached thereto. Fig. 4 is an end view of a side frame with the pedestals in place. Fig. 5 is a view in vertical cross`section through the side frame at the center of the pedestals. Fig. 6 is a view in horizontal section through the end portion of the side frame and one of the pedestals.

In carrying out my present invention I pre* fer to employ the construction of side frame set forth in an application for Letters Patent filed by me in the United States Patent Office September 3, 1896, Serial No. 604,812. The side frame is shown as formed from a plate girder or beam of metal (preferably steel) that is rolled to the shape Vshown in Fig. 1 of the drawings; that is to say, the side frame has a central web or bodyA, the top and bottom edges of which are thickened, preferably by lateral anges a, preferably on both sides, and beyond these lateral flanges manner that the pedestals can be withdrawnv horizontally or endwise from the side frames for the purpose of repairing or replacing parts.

In the preferred practice of my invention each of the pedestals consists of the inner and outer vertical sides or jaws B and B', that are united together by the top portion B2, and preferably these parts are formed from a single casting. The bottom of each pedestal is left open to receive the oil-box, dre., but when the pedestal is set in place within the side frame the bottom of the pedestal will be closed by the corresponding projecting part at the end of the side frame. Preferably, although not essentially, each pedestal has its inner jaw provided with flanges b, between 'which will be received the end of the web or body A of the side frame, and suitable bolts c will removably connect the pedj estal to said web or body. By preference also the top B2 of each pedestal. is formed with vertical ribs 1)',that will extend at each side of the upper projecting arm or portion at the end of the truck-frame, and similar projections b2 are shown as formed at the lower ends of the pedestal-jaws in order to more securely retain4 these jaws in position upon the lower projecting portion of the side frame. Through the outer jaw of each of the pedestals is formed a vertical hole b3 to receive a retaining-bolt D, that will pass through the reduced ends of the top and bottom projecting portions of the side frame, suitable nuts d being used to retain the bolt D securely in place. By preference each of the pedestals has formed in piece with its top and jaws a cap B3 to receive the upper end of the spring that is interposed between the pedestal top and the subjacent oil-box.

In placing the parts in position for use the truck-frame is first adjusted to the proper height in the horizontal position, and the pedestals are then placed over the oil-boxes (as are also the springs when springs are used on top of such boxes.) The wheels are then rolled toward the truck-frame, the pedroo i estals being guided into the open ended spaces formed by the bifurcated or projecting end portions of the side frames. The pedestals are then secured in place by the bolts c and by the through-bolt D, and the opening at the bottom of each pedestal is closed by the lower projecting end portions of the side frames. It will thus be seen that the lower ends of the pedestal-jaws are securely tied together and braced by the projecting lower portions of the side frame, so that the necessity of using separate parts for this purpose is avoided. By this means simplicity of structure is obtained and the number of parts is reduced, and,moreover, greater strength is given to the parts and the danger of their Working loose is avoided. When the wheels, axles, oil-boxes, or the like are to be removed for replacement or repaiigthe trucks will be jacked up slightly, the bolts I) and c will be withdrawn, and the pedestals will be removed endwise from the side frames, thereby permitting the oil-boxes, the., to be removed from the bottoms of the pedestals.

Preferably the side frames of the truck will be connected together by a bolster consisting of channel-bars E and E', the bent ends of which will be riveted, as shown, to the web or body A of each of the side frames and the flanged edges of which will be riveted to plates F, that in turn are riveted to the inward1y-projecting flanges at the top of the side frame.

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

l. A side frame for car-trucks formed of a rolled beam having open-ended spaces at its ends to permit the pedestals to be inserted into and removed horizontally therefrom, in combination With three-sided pedest-als formed with open bottoms and removably held within the end spaces of the side frame.

2. A side frame for car-trucks formed of a metal web, or body having top and bottom thickened edge portions projecting from its ends to form open-ended spaces for the pedestals, in combination with three-sided pedertals within the end spaces of the side frame, the bottoms of said pcdestals being closed by said web or body top and bottom thickened t edges projecting at its ends, in combination with three-sided pedestals removably held with-in the end spaces of the side frame', the bottoms of said pedestals being closed by the bottom projecting thickened portions of the side'frame.

4. A side frame for car-trucks comprising ametal'web or body provided at its ends with top and bottom projecting portions forming pedestal-spaces, in combination with threesided pedestals formed with open bottoms, said pedestals being removablybolted tothe Web or body and to the top and bottom projecting end portions of the side frame.

5. A side frame for car-trucks comprising a metal web or body provided at its ends with top and bot-tom projecting portions forming pedestal-spaces, in combination with threesided pedestals provided at top and bottom with vertical projections to engage the projecting end portions of the side frame.

6. A pedestal for the side frame of a cartruck formed of a single piece consisting of integral jaws or sides and top the inner jaw being iianged to engage the web and the top being flanged to engage the projecting end of the side frame and a spring-cap formed in one piece therewith.

7. A pedestal for the side frame of a cartruck consisting of integral jaws or sides and top the inner jaw being formed with double flanges to straddle the end of the body of the side frame.

8. A pedestal for the side frame of a cartruck consisting of integral jaws or sides and top, one of said jaws having a vertical hole therethrough to receive a bolt and the other of said jaws being flanged to permit it to be attached to the body of the side frame.
