CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 595,045, dated December '7, 1897.

Application filed March 2, 1897.

To all whom it may concern.-

Be it known that 1, WILLIAM E. (looks, of Kingston, county of Ulster, and State of New York, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

This invention relates to the construction of trucks intended particularly for electric locomotives, but also applicable to general streetrailway service.

The object of the invention is to devise a truck that shall possess great strength, durability, and efficiency and which is capable of supporting the car-body elastically upon the truck-frame independently of the support for the motor or motors, which latter are supported in part by motor-frames at the sides of the truck, suspended from the tops of the axle-boxes and being entirely independent of the truck-frame.

The invention will be fully understood from the description hereinafter given, taken in connection with the accompanying drawings, forming a part of this specification, and where in like features of the construction are indicated by the same numerals of reference in the several views.

In the drawings, Figure 1 is a side elevation ofatruckembodyingmyimprovements. Fig. 2 is a similar View with the main frame which supports the bolster for the oar-body removed, but showing the motor-supporting frame and appliances. Fig. 3 is a cross-section on the line 3 3 of Fig. 1, partly broken away. Fig. 4 is a detail sectional View on the line 4 4 of Fig. 1. Fig. 5 is a detail cross-section on the line 5 5 of Fig.

In the drawings, 6 designates the truckaXle, 7 the wheels, and S the journal-boXes, the latter provided in their top surfaces with depressions for receiving spiral springs 9, upon which the main side frames of the truck are cushioned, as explained hereinafter, and also provided with ledges 8 to prevent the displacement of the motor-supportin g frames, as shown.

The main frame of the truck consists of two castings 11, one at each side of the truck and of the configuration shown in the side view, Fig. 1, the cross-section of these frames at the top portion thereof being in the shape of Serial No. 625,689. (No model.)

I-beams, as indicated in Figs. 3 and 4. By referring to Fig, 1 itwill be seen that the frame 11 is cut out at 11" at both ends to receive or straddle the journal-boxes, and it is also cut away at the wheel-base or between the wheels to render the motors easily accessible and at the lower outer corners to give symmetry and reduce the weight of the structure and to give as much room as possible under the beam for operating mechanism. The frame 11 will thus consist of a longitudinal beam having two downwardly-extending arms near each end, forming two yokes for spanning the respective journal-boxes, with the lower surface of the beam being substantially on a line'with the bearing-surface of the yokes. In the tops of the cut-away portions 11 there are provided pockets, as shown, which receive the spiral cushioning- 7o springs 9, and the bottoms of such cut-away portions have bolted across the same the re pair-pieces 12. At the extreme ends of the truck its side frames 11 are connected together by the usual transverse beams 13.

At the longitudinal center of the truck there are arranged the cross-beams 14 14, which are bolted to flanges 15, cast with or connected to the inside of the side frames 11. These beams 14 14 are a sufficient distance apart to permit the requisite play of the swinging bolster and are connected transversely by the stay-bars 16. The bolster upon which the carbody is adapted to rest is indicated at 17 and may be of the usual construction. It is suspended from the side frames 11 of the truck by the links 18, two at each side of the truck, the same being pivoted to lugs 18 cast on said side frames, the said links 18 being in turn pivoted to eyebolts 19,which pass through the suspended cross-bars 20 and are provided below said cross-bars with spiral springs 21, held in place by cup-shaped washers 22 and nuts below said washers.

, It will be seen that there are two of the suspended bars 20, one at each side of the truck-frame. Supported centrally on thebars 20 is the swinging bolster 23, which is secured to the bars 20 by clamps passing under said bars, which are bolted at their upper ends to said bolster. On the bolster 23 are mounted the elliptic springs 24, one at each side of the truck. These elliptic springs 24: are secured to the beam 23 and also to the bottom of the car supporting bolster 17 by the ordinary elliptic-spring fastener or socket 21. The bolster 17 is therefore elastically supported on the elliptic springs 24, and the swinging beam 23, upon which said springs are mounted, is in turn elastically supported on the cross-bars 20,connected to the spring-equipped eyebolts 19, which are suspended directly from the truck-frame. By this construction the car-supporting bolster is flexibly and elastically supported on the truck. Springbuffers are indicated at 25 at the ends of the bolster 17 and serve the usual function of such devices.

The motor-sustaining frames 10, which support the weight of the motors, are of the configuration shown in the drawings, the same being depressed centrally between the wheelbase of the truck, with their outer elevated ends adapted to seat on top of the journalboxes 8, as clearly shown in the drawings. These motor-supporting frames 10 in the position which they occupy are outside of the I truck-frame 11, and they are wholly inde They support pendent of the truck-frame. the cross beams 10, upon which are mounted the spring-equipped standards 10, to which the outer end of the motor is connected by means of a ring or sleeve 10 on the motor,

encircling said standard, with a spring above and below the ring or sleeve.

The motor .is thus elastically suspended from the crossbeam 10. The support for the motors is by this construction wholly independent of any connection with the side frames of the truck, which carry the car-body and its load, or with the means whereby the car-body is supported j on the truck.

on'epiece, as shown. structure great strength and durability. will be understood from an inspection of Figs.

1 and 2 of the drawings th-atby removing the bolts connecting the repair-pieces 12 to the, side frames 11 at the bottoms of the journali boxes the said frames 11 may be readily re- 1 moved, together with the bolster and its suspending appliances.

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

1. In a car-truck the combination with the side frames, of links pivoted to said frames, eyebolts to which the links are pivoted, bars through which the eyebolts extend, springs on the eyebolts below said bars whereby the 1 bars are elastically supported, a cross-beam supported by said bars, one or more springs thereon, and a car-supporting bolster supported by the springs.

2. In a car-truck the combination with the side frames, of links pivoted to said frames, eyebolts to which the links are pivoted, bars through which the eyebolts extend, spiral springs 21 on the eyebolts below said bars, cup-shaped washers against which the spiral springs press, and a car-supporting bolster suitably supported on said beams.

8. The combination with the truck-frame and the journal-boxes, of motor-frames arranged outside the truck-frame and supported on the journal-boxes wholly independent of the truck-frame.

4:. The combination with the truck-frame and the j ournal-boXes, of a pair of motorframes arranged at the respective sides of the truck-frame and having depressed central portions at the wheel-base, and elevated end portions adapted to rest on the tops of the journal-boxes outside of the truck-frame and appliances supported by said motor-frames for sustaining the motor independently of any connection with the truck-frame.

5. In a car-truck, the combination with the journal-boxes and the truck-frame, of a motor-sustaining frame at each side of the truck, supported at each end on the journal-boxes and having a depressed portion between said ends, a cross-beam 10" connecting the two motor-frames and 1 supported thereby, springequipped standards mounted on said crossbeam, and adapted to sustain the motor independently of any connection with the truckframe.

6. In a car-truck, the combination with side 3 frames provided with openings near their ends The side frames 11 are preferably made in 1 They afford to the truck It to receive or straddle the journal-boxes, and springs arranged between the tops of said openings and the journal-boxes, whereby said frames are cushioned on the journal-boxes, of a car-body-supporting bolster elastically suspended from the side frames, and independent motor-sustaining frames supported at their ends on the journal-boxes outside of the main frames of the truck and depressed at the wheel-base of the truck, and elastic appliances supported by said motor-frames to sustain the weight of the motor.
