PASSENGER-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 625,745, dated May 30, 1899.

Application filed August 24. 1898.

T0 aZZ whom it may concern:

Be it known that LEDWARD CLIFF, a citizen of the United States, and a resident of Newark, in'the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Passenger-Car Trucks, of which the following is a specification.

The invention relates to improvements in trucks for passenger-cars; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

The invention is presented in this applicationas embodied inacar-truck having novel side frames, pedestal -frames, bolster, and

derstood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a top view, partlybroken away,

of a car-truck constructed in accordance with and embodying the invention. Fig. 2 is a vertical transverse section of same on the dotted line 2 2 of Fig. 1. Fig. 3 is a side elevation of the truck, the wheels being omitted. Fig. 4 is a detached perspective view of a portion of the pedestal-frame structure, and Fig. 5 is a detached side elevation of a portion of a modified formof side frame.

The side frames of the truck correspond with one another, and each comprises the upper bar A,'the lower bar 13, the lower pedestal-frame members 0, and the intermediate brace-bar D. Y

The upper bar A at its ends extends downward to form the vertical pedestal-frame members E E, and thence at its ends turns outward to form at the base of said members the horizontal bars or extensions F,through which pass the bolts G, by which the outer ends of the bars 0, constituting the lower pedestal- At its ends the lower bar 13 turns upward to form the inner vertical pedestal-frame members H, and thence at its ends turns outward below the upper bar A and forms at its ends the bars or extensions I, which terminate in close relation to the outer vertical pedestal-frame members E.

The upper bar A is in one integral piece, and the lower bar B is likewise in one inte: gral piece, and these two bars, in connection the side frame and pedestal-frames. The bars Serial No. 689,419- (No model.)

O are substantially of U shape and extend below the side frame of the truck and are, through their upper end horizontal portions, secured to the side frame by means of the bolts G and bolts J, the bolts Gr securing the outer ends of the bars 0 and the bolts J securing the inner ends of the bars 0 to the lower bar B, as clearly illustrated in Fig. 3. Within the pedestal-frames composed of the members E, H, and O is arranged the inclosed U-shaped pedestal-frame member K, (shown in perspectivein Fig. 4,) which member is flanged at its edges and snugly fits upon the vertical side edges of the said members E, H, and O and receives andafitords suitable rubbing-surfaces for the axle-boxes L. Uponthe axle-boxes L are provided the usual springs M, whose upper ends are held in the inverted sockets N, which are secured within the upper ends of the pedestal-frames by bolts or rivets O. The sockets N and springs M are of known construction and function. The axle-boxes L are adapted to have a vertical movement within the pedestalframes, and during such movement their guiding-surfaces directly contact with the surfaces of the pedestal-frame members K, and thus the wear occasioned by the movement of the axle-boxes does not come upon the main pedestal-frames, but is taken by the U-shaped pedestal-frame members K. The pedestalframe member K covers the joint between the lower pedestal-frame member 0 and the adjoining portions of the side frame and is preferably secured by bolts or rivets to the lower pedestal-frame member 0, as illustrated in Fig. 3. The vertical arms of the pedestalframe member K snugly fit between the vertical pedestal-frame members E H, but are capable of being drawn downward from between said members E H, and hence it will be apparent that the lower pedestal-frame member G and inner pedestal-frame member K may be readily applied to and removed from the side frame of the truck.

For the purpose of, imparting additional strength and security to the side frame I provide the bar D, whose outer ends are inter mediate the upper bar A and the ends J ofthe barB and whosemiddle portions extend downward on inclined lines to the central portion of the bar B and are there secured by bolts or rivets P. The ends of the brace-barD are se cured in place by means of the bolts or rivets 0, which sustain the inverted sockets N and afford the means for connecting the ends J of the bar B with the upper outer horizontal porwardly-turned flanges secured by means of the bolts or rivets P,which extend through the lower bar B, the lower central horizontal portion of the brace-bar D,and the lowerinwardlyturned horizontal flanges of the transombeams Q. Thus the bolts P secure together the lower flanges of the transom-beams, the central portion of the brace-bar D, and the central portion ofthe lower bar B. The transombeams Q extend outward to the outer vertical edges of the side beams, and hence they may not only be effectually secured to said side frames, but very securely'conneot the upper and lower bars of the side frames and perform their maximum duty in affording the requisite degree of strength, durability, and rigidity to the truck. Upon the outer end edges of the transom-beams Q are formed the vertical flanges R and bearings S, as more clearly-illustrated in Figs. 2 and 3, said bearings S being provided to receive the horizontal bolts T, from which are hung the links V, carrying at their lower ends the bolts W for the lower section a of the bolster-spring X, as clearly illustrated in Figs 2 and 3.

The bolster is letteredY and is in'the form of ac-h-a-une-l-beam, whose edge flanges turn downward between and are guided by the vertical -web portions of the transom-beams Q-and whose upper portions carry at their center the center bearing band at their ends suitable rub-irons d. The bolsterY extends beyond the outer vertical sides of the side frames of the trucli and passes below the upper bars A and between the transom-beams Q. At the lower side of the ends of the bolster Y are secured the sockets e for the ends of the upper section f of the spring X, said sockets loosely receiving the ends of the said section f and permitting of a limited sliding movement of said ends without losing their housing within said sockets.

The form of the bolster-spring X is illustrated in Fig. 2, and-in the present instance two of the said springs are employed, as illustrated in Figs. 1 and 3. As many of the springs X as desired may be employed. Each spring X is formed of a lower section CL and the upper section f, and these two sections are connected at their center by the band 9. The ends of the lower section a extend downward and outward and are secured upon the bolts W, and the ends of the upper springsection f extend outward and upward and are housed within the sockets e. The weight of the car is taken by the bolster Y and is sustained upon the springs X, which afford the proper ease of motion to the car. During the movement of thecar-bodythespringsections a f may approach one another at their ends and may have a suitable yielding action, owing tov the capacity of the links V to move outward and the freedom afforded to the ends of the upper spring-section f by the socket-castings e.

The side frames comprising the bars A B O are of simple and comparativelyinexpensive construction, but are of great strength and durability and are capable of being manufactured at the minimum expense. The side frames, constructed as above described, are capable of withstanding all of the usual strains to which car-trucks are subjected and are also of a character to bereadi-ly repaired. The lower pedestal-frame members 0 receive the inner pedestal-frames K, and the latter furnish the rubbing-surfaces for the axleboxes and prevent the-said boxes from wearing on the main pedestal-frame members. The lower pedestal-frame members 0 are suspended from the side frames, and hence the said members and the inner pedestal-frames K may be readily removed and replaced at will.

The transom-beams Q'not only connect the opposite side frames with one another, but

also connect the bars A B of each side frame with one another and materially add to the strength and efficiency of the side frames. The invention is not limited to use of Z- beams for the transoms; but when the transom-beams are of Z shape they will be found to be entirely efficient and of great advantage to the general structure of the truckframe.

The bolster Y extendsbelow the upper bars A-andis con-fined between the transom-beams Q. The transom-beams cooperate with the side flanges of the bolster Y in guiding said bolster and preservin g it in proper alinement. The bolster Y is mounted upon the springs X, and hence is at. all times yielding and eflicient.

I do not confine all the features of the inouter ends of the upper bar A to form the outer vertical pedestal-frame members E, and

hence in the modified construction shown in Fig. 5 I illustrate the lower bar B as passing upward and then outward and then downward to form three sides of the pedestalframe.
