11.0(LOllO'lIVE OR GAR TRUCK.

Application filed September 26, 1923.

To all/w71 om 'it may concern Be it known that I, AsA F. -BAToHnLDnn, a citizen of the United States, residing at Schenectady, in the county of Schenectady,

State of New York, have invented certain new and useful Improvements in Locomotive or Car Trucks of which the following is a specification.

My invention relates to locomotive or car trucks and particularly to trucks for electrically propelled locomotives or cars and has for its object to provide a novel and improved mounting for the motors of such trucks which will reduce the dead load on the axles. In locomotives and car trucks it is customary to mount one side of the m0- tors directly upon the axles and resiliently support the other side of the motor from a transom or truck frame. This reduces to some extent the dead weight caused by the mot-or on the transom or truck frame but leaves a portion of the` weight of the motor asl dead weight on they axles.

invention consists in providing improved resilient means between the axles and the motors to reduce to a minimum the dead weight upon the axles. Vinvention further consists in using the electric motors as a part of the mechanicalV portion of the truck, .supporting them between theV axles and transom, the transom being supported by equalizer-s which in turn are supported by the motor frames so that the whole truck structure including the motors is carried by the lresilient means 'interposed between the motors and the axles. In such a truck, the supports of the motors on the axles are used as the main journals, so that no outside journal boxes or any frame are required and at the lsame time by reason of my improvement t-he dead weight upon the axles will be reduced to a minimum.

Other features of novelty which characterize my invention will be pointed out with particularity in the claims annexed to and forming a. part of thisvspecification. For a bet-ter understanding of my invention reference may be had to the following description taken in connection with the accompanying drawings in which Fig. 1 is a side elevation of a truck embodying my invention; Fig. 2 is a plan view of the truck shown in Fig. 1; F ig. 3 is an end elevation, partly in section, of a truck embodying my serial no. 664,970.

weight upon the axles. I also provide supj ports on the motors 7 for equalizers 11 and support the transom 8 on springs 2d which are carried by the equalizers 11. The equalizers 11 are securedl to the motors 7 by means of pins 12- whieh pass through the equalizers 11 and lugs 13 formed on the motor frame. rhese equalizers by reason of this pin connection maintain the proper distance between the axles as will be pointed out hereinafter. Each of the motors 7 is geared to its respective axle through

gears

14 and 15. The motors 7 have a nose 16 somewhat similar to the ordinary nose on a railway motor, only larger, which fits intoy a recess 17 in the transom 8 so as to prevent up and down or sidewise movement of the motor 7 with respect tothe/transom. Part of the weight of each motor is thus carried by the transom 8.' The balance of the weight ofthe motor is carried by the axle 5. Mounted upon the axles 5 are the journal boxes 18 having bearings 19. Projecting from the framelof motor7` are overhanging jaws 2() whichengage the journal box 18 to secure thc-motor to the axle 5. Interposed between the journal box 18 and the motor frameare a plurality of sets lof leaf springs 21 aligned with each otherand with the axle and having their ends supported in pockets Von the top ofthe journal box 18 and supporting part of the weight ofthe motor 7 at their centers. This arrangement by reason of the resiliency of the leaf springs 21 will reduce to a considerable extent the dead load upon theaxles 5. To lubricate the bearing 19 and the springs 21, I provide an oil well 22 above the j ournal boxes 18 having outlets 23 which discharge oil over the springs 21 and into the journalbox 18. I thereby secure proper lubrication of the springs 21 and the bearings 19 from a common source. The proper distance between the axles is maintained by the two longitudinal bars 11 which act as equalizers and the jaws 2O formed on the motor frame which engage the journal boxes 18. rlhis construction prevents longitudinal movement between the equalizers ll and the motors 7 and between the motors and the axles 5. By this construction it is possible to dispense with the framework such as it has been customary to employ in the past, to secure propel' spacing of the axles. VThe transom 8 is supported on coiled springs 2li which are carried byplates 25 secured to the ends of tie rods 26. rlhe tie rods 26 are suspended from` the equalizers ll by means ofzplates 27 which straddle the equalizer-s.

AThe outer ends of the transom 8 form a support for the brake rigging and .air cylinders 28, the brake levers 29 being pivotally connected to the ends of the transom and inline with the. wheels G. The transom has a cavity extending from thecenter plate lopening 30 to outlets 3l formed in the side of the transom. lThese out-lets 3l areprovided with 'sliding sleeves 32 which are biased in an .extended position and engage the frame of the motors 7. 4The. motors 7 have openings or air inlets adjacent the sliding sleeves 32 to permit air to bev forced into the motors through the center plate opening 30 and the transom 8 for the purpose of .cooling them. The sliding sleeves 32fhave alinished surface which engages a similar finished surface surrounding the air inlet of the motors 7 and this in conjunctionewith the biasing means provides a tight joint be tween the transom and the motor frame for the circulation of the cooling'air and at the same time yper-mits relative displacement of the openings.

F rom the above it will be seen that all the weightv on the center plate together with the 4weight of the equalizers, the transom and the motors, will be resiliently supported by the springs 21 which. are interposed between the Amotors7 and .the journal boxes 1S and that the weight of the transom and the weight carried thereon. will be resiliently supported on the equalizers'by the coiled springs 24. I:Such a truck will ybe light in weight andwinexpensiveto -build,-as itvdoes `not requireanyvoutside journal boxes Aor out- Iside fra-me andl ati the same time by reason ofmy improvement the dead weight upon the axles will be reduced to a minimum.

I desire to have it understood that my invention is-not limited to the particular arrangen'ient shown and described, and I aim inthe appended claims to cover-all modifiw 'cations that do not depart from the spirit fand scope of my invention.
