CA R T R U C K SPECIFICATION forming-part of Letters Patent No. 529,284, dated November 13, 1894. Application filed April ll, 1894. Serial No.50'7t152. (No model.)

To a/ZZ whom t may concern:

Be it known that I, BENJAMIN F. MANIER,

Jr., a citizen of the United States, residing at Providence, inthe county of Providence and State of Rhode Island, have invented certain new and usefulImprovements in Oar-Trucks; and I do hereby declare the following to bea full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In United States Patent No. 510,277, granted to B. F. Manier December 5, 1893, is described and claimed a metal car-truck possessing certain novel features,that is a trussed continuous channel-bar having the axle-carrying pedestals rigidly secured to and located below said channel-bar, aplate secured to the car sill and a series of guided springs interposed between the plate and channel-bar, through which springs the weight of the car and its load is transmitted to the truck-frame.

My invention also relates to metal cartrucks adapted for street cars, and it consists essentially in the combination with a hollow pedestal, adapted to be secured to the car-base, and an axle-carrying box movably mounted therein, of an elliptic spring mounted between the walls of the pedestal and in engagement with the top of said box and braces or ties secured to the pedestal, as will be hereinafter described.

By means of this invention the Weight of the truck is reduced. Itis simpler and more accessible, and the vertical vibrations ot` the car are lessened.

A car provided with my improvement presents an attractive appearance, the arrangement of the parts at the same time being suoli that comparativelygreater strength and stiffness is attained with less weight.

In the appended drawings, Figure lis a sideelevation of the lower portion of a street-car provided with my improvement. Fig. 2 is a side elevation of the truck in enlarged scale, and Fig. 3 is an end view of the same.

Although my improved car-truck is more particularly adapted for street-cars yet it can be employed in other types ot' cars or vehicles.

As drawn a indicates the base or sill portion of the car provided on its under side with a longitudinally extending strip b of metal rigidly secured thereto.

c indicates the pedestal, so-called, the same having a vertical opening extending npwardly from its lower end in which opening the axle-carrying box d is fitted to slide, substantially as common. The pedestal is h0llow, its two sides being separated laterally and united at the top by a tie or plate c3 integral with the pedestal. The latter is secured to the sill-plate b by bolts b4, lips Zfurther serving to hold it in place. To the bottom of the pedestal a space-tie or cap c is removably secured. In the central part of this tie is formed a recess c2 to receive acoiled spring 75, the latter also bearing against the under side ot' the journal-box d, and forming a cushion or bumper. The said box d, as before stated, is fitted to move verticallyin the pedestal, side tlanges d2 serving to hold it in position longitudinallyof the axle. A slightly raised lip or rib n is cast on the top side of the box to form a shallow socket, in which socket is located a bent strap n; a similar device being located on the under side ot' the pedestal plate c3. Within these straps n are mounted and secured the leaves or layers of a full elliptic spring s, all as clearly shown. These springs extend in a direction longitudinally ot the car and are located between the front and rear sides of walls of the pedestals and are partially concealed thereby. The springs are fixed in position directly above the centerof the axle-boxes, as clearlyshown.

The two pedestals may be united at the bottom by a suitable tie, as r. The projecting or end portions of the car are stiened and braced by means ot' diagonal compression members or trusses p. The said trusses may consist ot' a metallic tube, one end beinginserted in an exterior socket (Fig. 2) formed 95 in the forward side of the lower part of the pedestal, the other being mounted in a step or plate p rigidly secured to the under side of the car-base; a screw p2 mounted in the step being employed to regulate or control IOO xo while the wheels w are in contact with the track-rails, while at'the same time the pedestal itself ismoving or vibrating up and down.

in unison with the car-body and sliding between the side flanges dict the axle-boxa r 5 In the patent hereinbefore referred to, as

well asin others of that class-having the pedestalsLnon-stationary with respect to the carbodyytheend truss is secured to the pedestal and-to. the forward end. of the longitudinal zo frame or girder towhichthe pedestal is secured. Consequently the vertical mo vemems or. vibrations ofA the car are-'practically independent of such fra-me or girde-r, since-l the latter is yieldingl y connected to the car-body.

:z5`4 Th.erefore=fsuch end trusses'do not support or sten the corresponding portions of the-car. I'n. the presentinvention itiwill be seen that the end truss or'brace p materially supports the end portion of the car, from the-'factthat it ist directly secured tothe car andto the pedestal, the latter also being rigidly secured to the car.

I claim as my invention- In a street car, a hollow pedestal c rigidly secured to the car-frame or base, oppositely 35 arranged inclined braces p, fastened to the lower portion of the pedestal and to the cartrame, a tie brace r uniting the pedestals and a bottom tie or cap c' uniting the two sides ot' the pedestal, all adapted to move vertically in unison with the car, in combination with an axle'.-carryin'g boxd loosely mounted in the pedestal, a light spring or cushiont interposed between and in contact withV said box and ti'e c and a full elliptic springs, arranged longi- 45 tudinally ot' the car, said springs being interposedbetweenandin contact withthe upper. side of they box and the 'underside oi the pedestal base c3, substantially as. described and for the purpose set forth.

In testimony whereof lhave affixed my signature inpresence of two witnesses y BENJAMIN F. MANIER, JR'.v
