CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 399,466, dated March 12, 1889.

Application filed June 7, 1888. Serial No. 276,358. (No model.)

To aZZ whom it may concern:

Be it known that l, \VILLIAM G. BAKER, a citizen of the lfnited Rt ates, residing at i Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Far-Trucks, of which the following is a specification.

My invention relates to that class of cartrueks in which the car-hody is supported on springs mounted in trames or carriages sup ported on the axle-boxes.

The object of the first part of my invention is to so arrange the springs and their frames or carriages, and so connect them to the carbody and to the axle-boxes that the car-wheels and their axle-boxes may he removed without removing the springs or unnecessarily disarranging the other parts of the gear.

To this end my invention consists in providing supports or iasteuings independent of the spring t'rai'nes or carriages to sustain the springs, spring-seats, and like parts when the wheels, axles, and spring-carriages are removed. In this connection my invention also consists in an improved way of constructing and organizing the springs, spring-posts, spring-carriages, guide-posts, and brace-rods, as will be hereinafter described and claimed.

The object of the next part of my invention is to provide improved means for supporting the griphars and life-guards oi the cars of cable railroads.

. To this end my invention consists .in providing the axle-boxes with hangers of an improved construction, having seats in. which broken away.

the grip-bars are mounted, and in which they E are free to rock. In this connection my in- I vention also consists .in an improved way of attaching the hangers to the axle-boxes, an improved form of grip-bar, an improved way of forming the seat for the grip-bar, and in i improved devices for limiting the movement of the grip-bar in its seat. 1

I11 the accompanying drawings, Figure 1 is i a side elevation of acanwheel with the truck- 1 gear therefor. Fig. 2 is an end view with the t wheel and grip-bar in section. Fig. 2% is a side view of the lower part of the car-wheel and its gear, showing parts oi. the gear broken away. Fig. is an end view of an axle-box with a car-wheel in section, showing also the grip-bar in section and parts of the geari Fig. 5 is a bottom view of the grip-bar and its hanger. Fig. ti is anelevation of a modified form of gear with my improved devices i'or supporting the springs in this kind of gear. Fig. T is a detailed view of a section of the braces, and Fig. 8 is a detailed view of the improved devices for supporting the springs.

The spring-carriage A is supported on the axle-box B by means of a link, l3, which rests on the top ot the box and passes through recesses u in the carriage adjacent to the box, and then under the bottom of the carriage. .The carriage A has laterally-projectiug arms or brackets A, on which rest guide-blocks C, which are held firmly in place on the carriage by means of lugs or dowels c, which it in corresponding recesses, c, in the upper face oi the brackets. If preferred, however, the guideblocks may be formed in one piece with the carriage. The guide-blocks also are provided with recesses rthrough which the link 1% extends.

On laterally-project ing arms ol 1 he guideblocks rest gum cushions D, carrying plates D, in the upper faces of which the lower ends of the supporting-springs are seated. The upper ends of the springs extend into recesses or seats E in a crossbar, F. The upper face of the bar F at each end is provided with seatsfi in which rest the gum cushions G, which also extend into seats g in the car-sill H. The spring-posts I are secured at their upper ends to the car-sill, and 6X- tend through the cross-bar F, the springs E, gum cushions D, plate I), guide-blocks C, and carriage A, and are serew-threaded at i to receive nuts 1, between which and the I bottom of the carriage are interposed gum washers l".

The openings 1" in the carriage are larger than the nuts I and the gum wash- 1 ers P, so that the. carriage may be withdrawn over the washers and nuts. The posts I are preferably shouldered at F. and the reduced ends pass through sect ion Ll oi? the brace-rods J. Nuts J, working on the screw-threaded ends of the posts, secure the rod-section J in position on the posts. Tlheform ot' thcbraeerod section is shown in Fig. 7.

The guideposts l\' are secured to the carsill ll, and extend through pcriorations K in the guide-blocks and in the spring-car riage. The lower ends of the posts K are preferably shouldered at 7c, and the ends extend through openings j in the brace-rod section J Nuts Ii, working on the screw-threaded ends of the posts K, secure them to the brace-rod section J The brace-rods maybe connected to the car-body in the usual way. I preferably, however, secure the section J to the main portion of each brace-rod by a sleevenut, J so that this section of the brace-rod may be removed without disarranging the other parts of the braces. The gear thus organized firmly supports the car-body on the axle-boxes. The boxes are free to move vertical-ly with the sp ring-carriages, being guided truly by the posts K, and the boxes may have a lateral movement within the links B in the usual way. By removing the nuts J and L and taking away the sections J X of the brace rods, the carriages may be removed from the posts I and- K, and taken off with the wheels, axle, and axle-boxes. without disturbing the springs, gum cushions, or cross-bars, and, when the guide-blocks are made separately, as shown in the drawings, they also are not disturbed.

Instead of placing the nuts I on the posts I they may be placed on the posts K, as shown in Fig. 3, and perform the same function, or they may be used in both places, the openings in the carriage being large enough to permit the carriage to be withdrawn over the nuts without removing them. hen the nuts I are placed on the posts K, as shown in Fig. 3, gum washers I- are arranged 011 the posts I between the brace-rod J and the bottom of the carriage.

In Fig. 6 a different form of cargear is shown,in which the link B is dispensed with and the carriage secured directly to the boX or formed therewith. The carriage h as brackets A, on which rest plates A provided with sea-ts for the gum cushions D. Plates D, resting 011 the gum. cushions, have seats for the springs E. Nuts; 1' are secured onto the posts below the carriage, and between the bottom of the carriage and the nuts are'interposed washers 1 The openings in the carriage above the washers and nuts I and I are large enough to permit of the carriage being withdrawn over them. The construction is similar to that described in connection with Figs. 1, 2, and 3 of the drawings, and the braces are connected in a similar way. The guide-blocks C are in this instance formed on the bracerod section J In cars for cable railways the grip devices are usually supported on frames located below the boxes. I propose to support the gripbars M on each side in a hanger, N, secured to lugs or ears in a saddle-piece, O, which extends over the top of the axle-box on which it rests. The saddle piece 0 is preferably made narrow at the top, Where it rests on the box, and widens as it extends downwardly by the side of the box. The cars or lugs 0 ex-' tend beyond the bottom of the box and the arms I of the hanger are secured to the lugs O by cross-bolts I provided with ren'iovable' a flexible connection to provide against undue strain. The arrangement also brings the weight under the center of the journals and admits of easy access for the removal of the wheels. In order to limit the vertical movement of the grip-bar and yet permit of its rocking, I attach a short bolt, Q, to the gripbar at the bearing-block and extend it through the bottom of the hanger. The lower end of the bolt is screw-threaded to receive a nut, R, and between the nut and the bottom of the hanger is interposed a washer, S, having a curved recess in its upper face to conform to the bottom of the hanger. The opening through the bottom of the hanger is slightly enlarged, as shown, so that the bolt may rock with the grip-bar. This arrangement is especially desirable when track-brakes are applied to the grip-bars. 'It will be observed that these devices for supporting the gripbars may be applied to any car-truck, as the saddle may be readily supported on the ordinary form of axle-box; but the saddle may be dispensed with if the lugs or ears are cast on the box. The grip-bars maythus be readily removed from the axle-boxes when it is desired to change the wheels.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
