EDGAR PECKIIAM, OF NEIV YORK, N. Y.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 424,723, dated April 1, 1890.

Application filed December '7, 1839. Serial No. 332,951. (No model.)

To all whom it may concern:

Be it known that I, EDGAR PECKHAM, of New York, in the county of New York, in the State of New York, have invented new and useful Improvements in Car-lrucks, of which the following, taken in connection with the accompanying drawings, is a full clear, and exact description.

This invention relates chiefly to the class of trucks employed on e1ectrically-propelled cars; and it consists in an improved construction and combination of parts, as hereinafter described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a car-truck embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical transverse section on line Fig. 4: is a vertical transverse section on line y y, Fig. 1. Fig. 5 is a detached perspective view of one of the saddles, and Fig. 6 is a side elevation of a modification of my improved car-truck.

Similar letters of reference indicate corresponding parts.

0 O designate the car-wheels, and O O the axles thereof.

D D are the journal-boxes. Upon each of the latter is mounted a saddle E, consisting of a horizontal bar 0, by which it rides on top of the journal-box, and which is braced by vertical flanges c 6 along its sides. Arms or jaws e e depend from the ends of the bar 6 and are formed integral therewith and embrace the sides of the journal-box. The said arms or jaws are formed with two shoulders d d on each of the inner and outer edges, and between said shoulders are fitted tightly edgewise the ends of longitudinal beam-sections B B, which are dual and riveted or otherwise rigidly secured to the inner and outer sides of the jaws e e. Said beams are thus firmly supported. and serve to securely tie the saddles to each other.

In order to further support the free ends of the end sections of the longitudinal beams B B, I extend the jaws e e of the saddles E E below the journal-boxes, and preferably bifurcate the ends of said jaws, as shown in Fig. 4 of the drawings, and in the bifurcation thereof I secure the horizontal beam of the truss O by bolts or rivets passing through perforations in the ends of the jaws and in the truss-beam, which latter is placed edgcwise vertically. The ends of the truss are extended obliquely upward and enter between the end portions of the dual beams 13 B and are riveted or bolted thereto.

A A represent the longitudinal top beams,

which may be composed either of wood or of the upper beam A, which is thus supported elastically vertically.

\Vhen two trucks are to be placed, respectively, under the two end portions of the carbody, I secure to the end portions of the upper beams A cross-beams G G, and preferably allow them a slight movement crosswise of the truck by connecting said beams to the beams A A by means of hinged couplings 72 72. Upon the cross-beams G G, between the beams A A, I mount a horizontal frame extending lengthwise of the truck, and preferably formed of longitudinal bars H H, resting with their ends on rubber or spring cushions z' 4 interposed between said bars and cross-beams G G. To the top of the central portion of the bars H H is securely fastened a metal plate P, which is provided with a socket or step 1) for the reception of the pivot secured to the under side of the car-body.

On a short truck I dispense with the truss C and attach to the lower ends of the jaws e e. the longitudinal bars, to the ends of which the snow-plow t is attached, as shown in Fig. 6 of the drawings, and also dispense with the end extensions of the beams B B.

0 denotes a longitudinally-channeled crossbar, which is secured at opposite ends to the lower side beams B B, and is thus carried a uniform distance above the track. In the channel of the said cross-bar I secure lengthwise thereof a wooden bar filling said channel,

so as to deaden the sound thereof. Across the center of this cross-bar I secure an up- 7 right frame R, which is preferably trapezoidal in form and seated with its shorter side upon the crossbar c; The top portion of this frame is formed with an extension R toward the motor, and when two of the latter are to be connected to the truck I form the frame R with two extensions R R forward and rearward from the frame. The heel l of the motor is connected to the extension R by a suitable coupling 'n, which may consist simply of a bolt suspended from the extension R' and passing through the heel Z, and provided underneath the same with a head or nut, and a spring surrounding the bolt between the heel Z and frame. Extension Raffords the desired upwardly-yielding support to the motor-heel.

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

1. In combination with the journal-boxes, the saddles E E, riding upon said journalboxes and formed with integral pendent jaws embracing the sides of the journal-boxes and extending below the same, longitudinal beams connecting said saddles to each other, and the longitudinal bar 0, attached to the lower ends ofsaid jaws, as set forth.

2. In combination with the journal-boxes, the .saddles E E, riding upon said journalboxes and formed with integral pendent jaws embracing the sides of the journal-boxes and .extending below the same, the longitudinal beams B B, composed of sections attached to the jaws of the saddles at opposite sides of the j onrnal-boxes, and the truss 0, attached to the lower ends of the aforesaid jaws and to the end portions of the beams B B, substantially as described and shown.

3. The combination, with the longitudinal side beams A A, of hangers connected to the end portions of said beams by hinged couplings, the crossbeams G G, secured to said hangers, longitudinal bars II H, mounted on the cross-beams, and the plate P, secured to the bars H H and provided with a step for the pivot of the car-body, as set forth and shown. I

4.. In an electric-motor truck, the combination, with the cross-bar c, of the truss R, secured transversely to the said cross-bar and extending toward the motor, and the heel of the motor hung to said extension, as set forth. 5. In an electric-motor truck, the combina- 'tion, with the cross-bar c, of the trapezoidal metal frame R, secured with the shorter of its parallel sides transversely to the aforesaid cross-bar and formed with the extensions R R on its longer side, and a coupling attaching the heel of the motor to one of the extensions R, substantially as described and shown.

6. The combination, with the channeled cross-bar c, of the wooden bar a, secured in the channel of said cross-bar lengthwise thereof, and a motor-support secured to the cross-bar, as set forth.

7. In combination with the journal-boxes D D, saddles E E, longitudinal beams B, con- EDGAR PEOKHAM. [n s] Witnesses:
