Application filed March 6, 1909. Serial No. 481,705.

To all whom 'it may concern:

Be it known that I, CLARENCE H. HOWARD, a citizen of the United States, residing at .St. Louis, in the State of 'Missouri, have invented a new and useful Improvement in Railroad MotonCar Trucks, of which the following is a specification.

My invention relates particularly to the side frames of a railroad motor-car truck and to the means for connecting the motorbed thereto, and is in the nature of a modification of my invention for which I have made application for Letters Patent of the United States February 26, 1909, Serial Number Ll80,130, for improvement in railroad motor-ear trucks, and my invention has for its obj-ect to provide a strong, rigid, and durable trucl{frame, and to increase the efficiency and stability of the truck by applying the motive power longitudinally through the upper portion or compression members of the side frames and thereby enable the said frames to be made of greater depth with the same amount of material while maintaining the normal height of the motorbed from the railroad track.

The invention consists in features of novelty as hereinafter described and claimed, reference being had to the accompanying drawing forming part of this specification, whereon,

Figure 1, is a to plan view of the side frames and connectlng members of my improved motor-car truck; Fig. 2, a side elevation thereof; Fig. 3, a vertical transverse section to enlarged scale, through the motor bed forming one of the`said members, on line 3, 3, in Fig. l, showing `its connection with the corresponding side frame (seen in side elevation broken away), and Fig. el, a

portion of the motor-bed at its junction and intersection with tho-side frame, on line 4, et, in Fig. 1.

Like letters and numerals of reference denote like parts in all the figures.

a represents the two opposite side frames of my improved motor-car truck which are connected together at and adjacent to the rear side of the bolster' b (indicated by dotted lines in Fig. l) by the preferably channel-shaped transverse member or transom c, and at and adjacent to the front side of the bolster b by the motor-bed d which is used in lieu of the ordinary transverse member the usual chafing or transom on this side of the bolster, the transverse connecting membersc and all being formed with suitable projections 1 for plates in en a Vement with corresponding plates on the o ster I), and with the usual anger brackets 2, while the side frames a are connected together at their front vends by the preferably channelshaped transverse member e, all the said parts, namely, the side frames a and the transverse connecting members c, d, and e, being preferably composed of cast steel cintegral throughout and having, preferably, suitable corner gussets or reinforcing horizontal webs, 4.-, and .5, at the junctions ofthe said members respectively, with the side frames a.

The motor-bed cl on which the gasolene engine or other suitable motor is mounted and fixed in the' usual Well-knownma'nner,

is in the present case preferably, concave' or trou h-shaped in cross section, of suitable widt and depth, and extends lengthwise between and preferably, intersects the upper portion or compression members of the side frames a, the top of the motor-bed@ being preferably, flush with the top of the side frames a.

Across and preferably, integral With the motor-bed l at suitable intervals along the same, are formed a series of upright webs or brackets 6 havin respectively, a bearing 7 for the driving s aft of the motor not shown), the bearings 7 being arrange in longitudinal alinement with each other transversely to the truck and having their longitudinal center preferably in the horizontal plane of the upper portion or compression members of the side frames a.

By the above construction in which the `motorbed cl is integral with, and forms a part of the compression members of the side frames, deeper and stronger side frames can be used with the same amount of material, and by applying the motive power from the drive shaft of the motor longitudinally through the compression members of the side frames as near as practicable to the railroad track, combined with the bracing ofthe side frames by their connecting transverse members integrally united therewith, a strong, rigid, and durable structure is obtained and the eiiiciency and stability of the truck insured.

f are suitably shaped openings formed transversely through each side frame av for receiving the equalizer-springs (not shown) Within the body of the frame below its top member, whereby suficient clearance is insured between the top of the frame a and the car-body, the top wall of each opening j' having a spring-seat 8 preferably integral therewith.

What I claim as my invention and desire to secure byLetters Patent is l. In a railroad motor-car truck, the combination with the side frames thereof, of the. motor-bedadapted to connect the said frames together transversely to the truck, and integral therewith, substantially as described.

2. In a railroad motor-car truck, the combination with the yside frames thereof, of the motor-bed, and a transom, adapted respectively, to connect the said frames together transversely to the truck and integral therewith, substantially as described.

3. In a railroad motor-car truck, the combination with the side frames thereof, of the motor-bed, and a front member, adapted respectively, to connect the said frames together transversely to the truck, and integral E therewith, substantially as described.

truck, and integral therewith, substantially as described. Y

5. In a railroad motor-car truck, the combination with the side frames thereof, of the motor-bed adapted to form a part of the compression members of the saidY frames and integral therewith, substantially as described.

6. In a railroad motor-car truck, the combination with the side, frames thereof, of the motor-bed adapted to intersect the compression members of the said frames and integral therewith, substantially as described.

7. In a railroad motor-car truck, the combination with the side frames thereof, of the motor-bed, and a transom, adapted respectively, to connect the said frames together transversely to` the truck and integral therewith, the said bed intersecting the compression members of the said frames, substantially as described.

8. In a railroad m'otor-cartruck, the combination. with the side frames thereof, of the motor-bed adapted to connect the said frames together transversely to the truck and integral therewith, the said bed having corner gussets at its junctions with the said 4. Ina railroad motor-car truck, the combination with the side frames thereof, of themotor-bed, a transom, and a front member, adapted respectively, to connect the said frames together transversely to the i i i l frames, substantially as described.
