SIDE FRAME FOB CAR-TRUCKS.

Patented Aug. 29, 1916.

Application `filed May 19, 1915. Serial No. 29,181.

To all whom it may concern: j

Be it known that I, THOMAS F. TOMLIN- son, a citizen of the United States, residing at Norfolk, inthe county of Norfolk and State of Virginia., have invented certain new and useful Improvements in Side Frames for is 'a l side frames which are detachably associated with the truck, to permit expeditious removal ofthe frames, although positively.

retaining the axis from Adisplacement during movement.

.A' further object of the invention is to provide side iframes which will permit removal of the journal boxes, but will positively prevent accidental displacement of the journal boxes, should the hinged ends of the frames become accidentally disengaged, at the same time, requiring a minimum elevation in order to remove the journal boxes from the car frame.. l

Other objects as well''as the nature, characteristic features and scope of my invention-will be more readily understood from the following description taken in connection with the accompanying' drawings and .pointed out in the claim forming a part of this specification. l

Referring to the drawings: Figure 1 is a side elevational view -of a side frame constructed in accordance with my invention one of the hinged ends thereof being swung downwardly in an open position, Fig. 2 is a detail elevational fragmentary view of a side frame constructed in accordance with my invention, illustrating the application of the same with a car wheel, axle and journal box, said axle and journal box being shown in section, Fig. 3 is a detail enlarged perspective fragmentary view of one of the side frames used in this invention, Fig. 4 is a ytransverse sectional view of a side frame constructed in accordance with my invention, illustrating the application of the same, and Fig. 5 is a plan view of the bolts used in this invention.

In the drawings, in order to illustrate the application of this invention, car wheels '1 are provided which are rotatably mounted upon axles 2 in the usual manner, the free ends of the axles 2 having journal boxes 3 associated therewith. 'Flangcs 4 are formed upon said journal boxes 3, andare arranged in spaced-apart relation to provide an annular groove 5 in each of said journal boxes, as shown to advantage in Fig. il.

' My improved side frame is generally designated in the drawings at 6 and comprises a skeleton body having a supporting column 7 formed approximately midway its ends and in which a longitudinally extending recess is formed to receive the truck bolster 8 and a. spring plank 9 of the usual configuration, the latter being hel(1 in spacedapart relation through the medium of coil springs 10. The terminals of the frame, are provided with hinged portions 11, each of said portions comprising an angle iron, one end of which is bifurcated as indicated at l2 for pivotal engagement with the lower end of the body of the frame G, the opposite end of said right-angled portion being reduced as indicated at 13 and mounted bctween the branches of a bifurcated portion 14 of the body of the frame 6. Vhen the angled portion 11 on each end of the body of the frame 6 is in alocked position, an oblong opening 15 is provided, adapted for the reception of a journal box, the frame Gbeing held from displacement on the journal boxes in either direction, in view of the flanges 4, heretofore described. The angled portions 11 are held in engagement with the frame 6 by bolts 16, the latter being held from displacement by cotter pins 17 although it is to be understood that any of the bolts may be removed, if so desired,and when one bolt is removed on either end, the other bolt will provide an axis, so as to permit the angled portion 11 to be swung either upwardly or downwardly in a vertical plane, thereby permitting the journal boxes to be removed when so desired. It is customary, however, to permit the angled portions 11 to swing downwardly, since the weight of these portions will cause them to gravitate to the farthest point of movement, thereby permitting 'lli the journal boxes to be removed when the frame (3 is very slightly elevated, it being, of course, necessary to elevate the frame in view ofthe bifnrcated ends 14 of said frame, said bifurcated portions being turned at right angles to the longitudinal axis of4 said frame, and serving in the capacity of abutments, so as to prevent the journal boxes from being casually displaced, should the angled portions 11 of said frames be acciertheless movement is limited, in view of the fact that saidportions swing in the path of the side frame to abut the latter, since the lower marginal edges 111 of the angled portions, adjacent their pivot points, will engage the shoulders 112 of the side frames as shown to advantage in Fig. l.- The shoulders 112 are formed -by reducing ,the ends of the side frames, as indicated in Fig. 3, said reduced portions being pivotally ar,-

'ra-nged between the branches of the bifurcations 12. By this construction it will be y impossible for the angled portions 11 to swing into contact with the rail ties in the event of casual disengagement of the upper ends of the angled portions, since the latter will not be permitted movement below a plane on a parity with the top of the rails.

It will be understood that the above del scription and accompanying drawings comprehend onl the general and preferred einbodiment o my invention and that various minor changes in details of construction, proportion and arrangement of parts may be A side frame for car trucks including a body having openings ladjacent its termi-v nals to accommodate journal boxes therein,

`a portion of each terminal being removed to permit engagement of the journal boxes in `vsaid openings and removal of the same therefrom, the terminals of said portions being formed to engage corresponding parts of the body, each removable portion lbeing operable on either of its ends as an axis, portions of said body lying in the path of movement of 'said movable portions to limit their downward movement to a plane on a. parity with the parts of said frame which engage the upper terminals of said removable portions bemg depended to provide abutinents for preventing casual displacement of the side frames in the event of displacement of said movable terminals.I

In testimony whereof I ax my signature in presence of two witnesses.
