ANTIVIBRATING CAR-TRUCK.

SPECIFICATION forming part of. Letters Patent No. 656,381, dated August 21, 1900.

Appllcationfiled October 19,1899. Serial No. 734,138. on model.)

To ctZZ whom it may oonccrnf Be it known that we,LuTH R'O.THoMPsoN, residing at Ouyahoga Falls,and FRANK KIRK, residing in the city of Akron, county of Summit, and State of Ohio, citizens of the United States, have invented a new and Improved Antivibratin g Car-Truck, of which the followin is a ful1,c1ear, and exact description, that wil enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, that form a part of this specification. I

First. One object of our invention is to sever the circuit of vibration between the cartrucks and the carand to overcome compound friction at the curves of the road and to thereby economize in power.

Second. It is also our object to support the car upon antifriction-rollers located over the journal-boxes of the motor drive-wheels, having radial centers that connect the trucks to the car and bracing the frames by a pair of reaches that receive the vibratory shocks from the armatures and car-wheels, substantially bracing the truck-frames, preventing a derailment of the guide-wheels.

Third. It is our object to prevent a shearing cut of the motor-wheel flanges upon the rails when passing around a curve in the track, thereby obviating friction and reducing the centrifugal force of the car and permitting of a high speed with greater safety.

Fourth. It is also our object to cushion the vibratory shock through the reach connections.

Fifth. It is our object to increase the adhesiveness between the wheels and the rails,

enabling the car to ascend and descend grades Figure 1 is a top plan view. Fig. 2 is a front elevation of the motor-bar. Fig. 3 is a top view of one of the reaches detached. Fig. is a side elevation of the depression or ten sion reach. Fig. 5 is a side elevation of the trucks.

Similar characters refer to similar parts throughout the several views.

In carrying out our invention we provide a pair of maximum traction-trucks A, one for each end of the car. Each of these trucks consists of the truck-frame 20,provided with large drive-wheels and small follower-wheels, the axles of said wheels being j ournaled in the ordinary or anypreferred way in the pedestals B. The motors Pare geared to the driver-axles in the usual way, the inner or horn end of the motor being supported upon the motor-bar C through the medium of the box 0, through an aperture in which the horn of the motor projects. Spring-cushions R and S are provided below and above the box a in the guideway D, with which the motor-bar O is provided.

nor end beams 23 and the outer end beams 23, which serve to connect the side frames together and preserve the parallelism of the frame. A transom-beam 24. connects the side frames together,being secured thereto at a point between the motor-bar O and the follower-axle of each of the trucks.

The weight of the car-body is supported over the pedestals B by the antifriction-rollers a, the pivotal points of the truck being located over the center of the driver-axle.

Connecting the transom-beams 24 of the two trucks are the duplex reaches L L. These reaches are each composed of the upper spring-steel bar 1 and the lower trussed bar 2 3, the member 3 being suitably cambered, so that the strut-thimble V may be inserted between it and the member 2. The endsof the members 2 and 3 are rigidly secured together by the rivets X X. The'upper memher 1 of the reach is secured to the lower truss member by the bolt 9, a spaeing-thimble V being inserted between the said members to properly separate them. Bolts 5 and 5' pivotally connect the ends of the reaches to the about midway between the middle and the ends thereof, and whenthepartsofthe truck: frame and reach are assembled these supple: mental bolt s.8 and 8 are outsideof the end beam 2,3.of th ruck-fr me n e ra e limit theipivotal actionot' the truck-frame,

Rub-irons are secured to the under side of t euppe m mb 10f t e at t e point; Where said member crosses the end beam 25* of the truck-frame.

In assembling reaches andthe truelpf-rarnes theupper members l of the'reach esare placed" abo and he o r embers wer placed. below the end beams23and transoms 2 4, and}- theirends are pivotally securedto said tran,-

sornsby means of the bolts 5 5", asshown in Fig. 1-. It will thus be seen that any tend e ey h nne n f e meekr me to. ri ev 0f h we he s e eeme erailed will be resisted by the yielding pressure of the reaches upon the end beams 23 n it e tr n msflee rt he uppe 'ting ofthe car-body directly over the driving x ee ehhtue p rmit ea p v a 1 swiveling action of thetruck, thereby obviate ng he un a y gr nd ng a d wea up the flanges of the driver-wheels and permit. ting thefollower-Wh eels to subserve the sole purpes o i h they a e pr v ded,viz-, t at Q et ng as gh d r e o p operly canryingthe trucks around'curves, and there;v by preventing derailment.
