CAR-TRUCK.-

SPECIFICATION forming part of Letters Patent No. 563,187, dated June 30, 1896.

Application filed March 6, 1396.

To all whom itmay concern:

Be it known that I, GEORGE \V. LACY, a citizen of the United States, residing at Kingston, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Oar-Trucks, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to that class of trucks especially designed for use on cars which are driven by their own motors.

The principal object of the invention is to provide a car-truck the sideframe of which between the pedestals may be easily lengthened or shortened without the necessity of changing the shape or angles of the pedestalcasting when it is desired to increase or diminish the length of the wheel-base line, thereby doing away with the trouble and expense of keeping different shaped and angled pedestals on hand to fit the side frames of trucks which have a different length of wheelbase line.

A further object of my invention is to provide a car-truck the side frames of which shall be as strong as possible and yet be comparatively light in weight and have the greatest powers of enduring both lateral and vertical strains, and to provide a car-truck with springs between the axle-box and the pedestals, and with springs between the side frames and bolster-plates, so that the oscillation of the car-body when the car is in motion will be reduced to 'a minimum.

The invention consists of the novel features of construction hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings, Figure 1 is a plan view of a car-truck embodying my preferred form of invention with the bolsterplate and load-bearing springs supporting said plate removed from one side of the truck. Fig. 2 is a side elevation of said truck, partly in section and partly broken away. Fig. 3 is a section of the pedestal on the line 3 3 of Fig. 4:. Fig. 4 is a central vertical section of the pedestal and axle-box. Fig. 5 is a horizontal section of the same on the line 5 5 of Fig. 4. Fig. 6 is a vertical section of the same on the line 6 6 of Fig. 4. Fig. 7 is a central vertical section of the tie-piece or tie- Serial No- 582,017. (No model.)

plate. Fig. 8 is a top view of the springseats, partly in section. Fig. 9 is a modified form of the outer ends of the bar members and springs. Fig. 10 is a section of the same on the line 10 10 of Fig. 9. Fig. 11 is a front view of the guide and support for the brakehead. Fig. 12 is a modified form of one truss portion when the lower-bar member is double. Fig. 13 is a section of the same on line 13 13 of Fig. 12. Fig. 14 is a section on the line 14: 14 of Fig. 12. Fig. 15 is a central vertical section of the tie-plate when the lower-bar member is double.

Like letters refer to like parts throughout the several views.

In the drawings, A denotes one of the side frames of the truck, and A the other side frame on the opposite side of the truck. Each of these side frames is a duplicate of the other, their corresponding parts being similar in form, construction, and arrangement. A description of the side frame on one side of the truck will therefore be suflicient.

B B are the wheels, 0 O the axles, D D the axle-boxes, and E E the pedestals holding the axle-boxes in position.

a a denote lugs on the axle-boxes, which form seats for the load-bearing springs ct a.

e 6 denote bridges made integral with the pedestals, forming seats for the upper portion of the springs a a, which are adapted to fit into the chambers a a in the pedestals, which are supported mainly by these springs.

b is a bufier, made of rubber or other suitable material, located between the top of the axle-box and the bridge I), made integral with the pedestal.

The pedestals E E are made preferably in the form of a yoke and of malleable iron cast in one piece, provided with cylindricallyshaped webs c c, gradually tapering at the forward and rear ends and terminating at their lower forward and rear ends in horns or projections c 0, thereby forming jaws c 0 d cl denote ribs or shoulders on the pedestals, cl d flanges, and d d rivet-receiving.

sleeves, all preferably made integral with said pedestal to prevent the rattling of parts when the car is in motion. These pedestals are adapted to slide down over the axle-boxes to keep them in position, the chambers a a fitting over the load-bearing springs a a. The

Ice

distance from the outer side of the pedestal to the inner side is about five inches.

lVhen the lower-bar member of the side frame is composed of double bars, as shown in the modification shown in Figs. 12, 13, 14:, and 15 of the drawings, the lower part of the yoke of the pedestal is provided with shoulders (Z (Z, flanges cl (1, and rivet-receiving sleeves d (1 similar to those of the upper portion of the pedestal and the horns or projections 0 c are dispensed with.

The side frame in my preferred form of invention is composed of the upper-bar members F and F, identical in form, construction, and arrangement, and the lower-bar member G, in connection with the pedestals E E and the tiepieces or tie-plates hereinafter described. The upper-bar members have two obtuse-angled portions united by a central bar portion. The lower-bar members are similar in configuration, the lower member having its angles inverted and opposite the angles of the upper member, whence it results that the entire side frame is symmetrical in figure, not only longitudinally, but bilaterally, the extreme ends forming acute angles of equal slope, or isosceles triangles, taken in connection with the inclosed pedestals. This form insures great strength, as well as the capacity for being made of any required length without modification of design. These upper and lower-bar members are secured by means of bolts at theirouter ends to the castings h 7t, provided with spring-seats k 7L2 to accommodate and support the springs h 71 For convenience of description the upper bar members may be subdivided into the parts f f f f f f and the lower-bar members into the parts g g g g g.

\Vhen double-bar members are employed in either the upper or the lower members of the side frame, the bars are made preferably of fiat steel about three inches wide and onehalf an inch in thickness, the said steel plates being preferably vertically disposed as to greatest width. The above dimensions are however only approximate and may be varied according to the weight of the load to be carried and the service in which the truck is to be employed. The parts f f are connected with the flanges on the pedestal and form an obtuse angle with each other. The parts g g areconnected with the lower portion of the pedestal and likewise form an obtuse angle in relation to each other. The outer ends f f g are extended, so as to form an acute angle near their outer ends. The central-bar members f f connect,respectively,the upper-bar members f f and the lower-bar members 9 g These central-bar members f and g are a short distance apart from each other and, as shown in the drawings, substantially parallel with each other. I do not, however, hereby intend to limit the invention to a side frame wherein the central members are substantially parallel,as it is obvious that as long as they are a short distance apart and do not intersect or cross each other the spirit of my invention will not be departed from.

i 2' denote the tie-plates connecting the upper and lower-bar members, located between the upper and lower-bar members, so as to prevent the bars from bending sidewise or vertically. Each of these tie-plates consists, preferably, of a single casting provided with rivet-receiving sleeves z" i, made integral with it, and with ledges or shoulders i i at its upper part, upon which the bar members rest, and terminating at its lower part into a jaw i in which the lower-bar member is secured. hen, however, the lower-bar memher is composed of double-bar members, the lower portion of this tie-plate is constructed similar to the upper portion, as shown in Fig. 15.

it it denote the motor hanger-bars having their ends attached to the vertically-movable spring-bolt k, which has its upper end attached to the spring k seated in the cupshaped casting k secured between the upperbar members by means of rivets, the inner ends of which are countersunk, so as not to interfere with the working of the spring k These castings k serve also as tie-plates to bind the upper-bar members together.

Z Z are cup-shaped castings secured between the upper-bar members by means of rivets Z Z, the heads on the inner ends of which are countersunk, so as not to interfere with the working of the springs Z Z which are seated in said castings. These castings also serve as tie-pieces to bind the upper members to gether.

m m denote castings secured between the upper-bar members and serve not only as seats for the elliptical springs m m, but as tie devices between the upper-bar members.

'n denotes the bolster-plate upon which the.

car-body rests and is designed to be secured. The bolster-plate is supported by and rigidly secured to the various springs heretofore described, located between it and the side frame of the truck.

0 is a stay or compression piece or repairpiece, adapted to fit into the recess between the lower ends of the pedestal-yoke. This repair-piece is provided with lugs or shoulders 0 0, which brace against the sides of the pedestal ends-and prevent the lower portions of the pedestal-yoke from being bent together. 0 denotes a cup-shaped chamber in said stay-piece which serves as a seat for the spring 0 located between the stay-piece and the axle-box. These stay-pieces make the lower-bar member or members of the side frame practically continuous and unbroken, and are removably secured by means of bolts 0 0 passing through the rivet receiving sleeves 0 0 and the lower part of the pedestal-yoke. The stay-piece may therefore be easily removed, so as to permit the axles and wheels and axle-boxes to be taken out of the side frame whenever that may be desirable.

1) denotes the brake-head, and p the brake- IIO shoe. The brake-head is provided with an arm orprojection 10 which is adapted to slide forward and backward as the brake is put on or off in the guide 11 secured to the lower bar member or members. V

p p denote the brake-beams connecting the brake-heads on each pair of wheels, and

p springs attached to a cross-bar for keeping the brake-shoe normally out of contact with the wheels.

1) denotes a lever, and 19 13 19 19 connections between the brake-head and powertransmitter for actuating the brake.

The various parts of the side frame are secured to each other and with their connecting parts by means of rivets driven and headed, preferably when red-hot, where it is not otherwise specified, to insure greater strength and to prevent the parts from becomingloose and rattling.

In Fig. 9 a modification of construction is shown at the outer ends of the side frame, which consists of an extension of the upperbar members to accommodate another spring between the side frame and the bolster-plate, so that the frame may be lengthened to accommodate itself to the car-bodies of open cars.

q is a spring-bolt for the purpose of counteracting the upward tension of the springs 71/3 h and at the same time relieve the other springs from the push and thrust of the carframe when the car is set in motion.
