CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 471,061, dated March 15, 1892. Application filed October 30, 1890. Serial No. 369,785. (No model.)

To all whom it may concern.-

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

This invention consists, rst, in an irnproved construction and combination of the side bars and subjacent truss-bar, of atruckframe united at the central portions to increase their rigidity and to support more firmly the support of the heel of the motor; secondly, in the combination, with the journal-boxes, of longitudinal side bars supported thereon and formed with a depressed central portion which permits the removal of the motor through the side of thetruck; thirdly,in the combination, with the car-truck and electric motor, of a pendulum or flexible hanger supporting the heel of the motor and allowing said motor to accommodate itself to the variations of the alignment of the truck; fourthly, in the combination, with the car-truck and electric motor, of asupport for the heel of the motor provided with rubber cushions on top and bottom of said heel to relieve the motor from'undue concussion in starting the motor and thus obviate the danger of breaking the motor-gear; fthly, in novel means for preventing the carrbody from shifting on the truck; andthe invention furthermore consists in certain novel features of the details of the truck and its aforesaid attachments, all as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure l is aside elevation of a car-truck embodying my improvements. Fig. 2 is a top plan View of the same. Eig. 3 is a vertical transverse section on line c cc, Fig. l. Fig. a is a detached enlarged perspective view of the track-scraper. Fig. 5 is an' end view of the same with its attachments; and Fig. 6 is an enlarged vertical transverse section of the support of the heel of the motor.

Similar letters of reference indicate corresponding parts.

A A represent the carwheels, and B B the journal-boxes, in which the axles of the aforesaid wheels are journaled.

F F-denote the pedestals, which are rigidly body to be supported elastically vertically on' the truck-frame, as hereinafter described.

Upon the j ournal-boxes are hung the yokes ct ct, which are formed with depending hangers a a', extending below the journal-boxes. To the inner vertical limbs of said yokes at points above the hangers are rigidly attached the longitudinal side bars D D, extending from yoke to yoke, and to the outer limbs of the yokes and in line with the ends of the bars D D are secured longitudinal bars D D', extending toward the ends of the car-body.

To the lower ends of the inner hangers ct a is attached a longitudinal truss-bar O, and end braces C C are extended from the outer hangers to the end portions of the bars D D and rmly secured thereto, as shown in Fig. 1 of the drawings. Straps C extend across the two hangers of each yoke and are secured thereto, and, if desired, also to the end braces C O to form ties between the central trussbar C and said end braces. Said straps are detachable to allow the journal-boxes B to be removed downward from the yokes and thus facilitate the removal of the axles and Wheels from the truck-frame when desired. In order to strengthen the truss thus formed, I unite the central portion of the bars D D to the subjacent portion of the bar C, preferably .by depressing the said portions of the bars D D to the plane of the bar O and riveting or bolting them together. By this construction an opening is formed in the side of the truck, which permits the removal of the motor through said side when required. Upon the said united portions of the bars D D and O,I

mount pedestals I-I, which are formed on their base with downwardly-extending iianges, by which they are bolted to either the inner or outer sides of the bars D. To the said pedestals is rigidly attached a stout'cross-bar E, preferably consisting of a longitudinallychanneled iron or steel bar, and to this crossbar, central of the length thereof, l attach a frame I, disposed at right angles to the bar and formed with horizontal longitudinal eX- tensions I I', upon either of which the heel c of the motor is hung or two motors may be thus supported. To allow the heel of the 1110- tor sufficient lateral play, so that the motor may accommodate itself to the variations of the alignment of the truck when passing around a curve of the road, I connect the heel of the motor to its support I by a pendulum hanger or laterallydiexible hanger CZ, of any suitable form. For exemplitication I have shown the hanger CZ in detail in Fig. 6 of the drawings, and it consists of two bolts e c', hinged to each other at one end, as shown at e. The bolt c passes through an eye in the support I', and is provided with nuts ffabove said support, and a collar f below the same. The other bolt c passes vertically through an eye in the heel c of the motor, and is provided with nuts ffbelow the said heel and with a collarf above the same.

To guard against undue concussion and danger of breaking the motor-gears incident to the vertical thrust of the heel of the motor when starting the motor, I interpose between the heel c and collar f a rubber cushion h and washer 7L', and a similar cushion and washer between the said heel and the nuts f. The motor may be further cushioned by placing a rubber washer 71l and a metal washer 7L between the top of the support I and nut f, and a rubber washer 71. between the bottom of said support and the collar f on the bolt e.

The car-body is supported on the longitudinal bars D D and D D by springs L L, mounted on said bars adjacent to the yokes ct ct and on the end portions of the bars D D', and in order to prevent the car-body from shifting longitudinally and laterally and to relieve the pedestals F F from undue strain, I provide the cross-bar F. with vertical guides 'i fr', and rigidly secure to the under side of the carbody vertical stays jj, which pass movably vertically through said guides, as shown in Fig. 3 of the drawings.

N represents a track cleaner or scraper, which consists of an elongated steel or iron plate, to the central portion of which is rigidly attached a short supplemental plate N, the bottom edge of which projects slightly below the bottom edge of the plate N. This track-cleaner is disposed diagonally across the track-rail and with the supplemental plate N directly over said rail, and is attached to the end extensions of the cartruck,and thus supported independently of the car-body or any other vertically-movable part of the car. Said track-cleaner may be made adjustable vertically by pivoting the front end of the plate N to a bracket Zr., attached to the plank or plate O, which extends across the end of Ltripel the truck-frame, and is secured to the ends of the bars D D. The rear end of the scraperplate N in that case is sustained on a rigid guide P,secured to the bar D and extending downward therefrom. The lower end of this guide is bifurcated to receive the rear end of the aforesaid scraper-plate, as shown in Fig. 5 of the drawings, and is provided with a vertical slot, through which passes a bolt k', which also passes through an eye 7c in the scraper-plate. Said plate can be raised or lowered in the guide I), as may be desired, and by means of the bolt K it can be clamped in its adj usted position, and thus the scraper can be supported in its raised position during such weather or season of the year when it is not required.

In order to enable the person in charge of the car to control the track-scraper from the platform of the car, the scraper may be provided with a rigid upward-proj eetin g arm N", and the cross-bar Z may be pivoted to the truck-frame, to which cross-bar may be fastened two crank-arms Z Z', which are connected at their free ends to the arms N N of the two Scrapers at opposite sides of the truck. A lever Z, rigidly attached to the cross-bar Z, is by a rod t connected to a hand-lever Z, pivoted to the platform of the car, as shown in Fig. l of the drawings.

To the rear of the scraper-plate N may be attached a spring-arm fr, which is curved and extended toward the t1ack1ailand has affixed to its lower end a small plow fr', adapted to enter the groove of a crossing-frog in the track, so as to clean said groove.

R represents the life-guard secured to the end ot' the truck to guard the car from running over obstacles in front of it. The front end of said life-guard is supported by the brace-rod 0, connecting it to the upper end of the post o', which is secured to the front end of the truck-frame.

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

l. In combination with the journal-boxes on one side of the truck, two side bars supported one above the other on said journalboxes and united at the central portion of their lengths, as set forth.

2. In combination with the journal-boxes and yokes hung thereon, hangers depending from the yokes, a truss-bar attached to the lower ends of said hangers, and side bars attached to the yokes above the hangers and having their intermediate portions united to the corresponding portion of the truss-bar, substantially as set forth.

Incombinationwiththejournal-boxesand yokes hungthereon, hangers depending from the yokes, a truss-bar extending straight from the hangers of one of the yokes to the hangers of the other yoke and secured thereto, and side bars secured to the yokes above the han gers and having their intermediate portions depressed and secured to the corresponding por- IOO IIO

and yokes hung thereon, hangers d a', de-A pending from said yokes, the bars DD, secured to the yokes and extending toward the ends of the car, bars D, extending from yoke to yoke and attached thereto, and the bar C,

. secured to the lower ends of the hangers and having its intermediate portion united to the corresponding portions of the bars D and the end portions of the bar C extended and secured to the end portions'of the bars D D', substantially as described and shown.

6. In combination with the journal-boxes, side bars supported on said journal-boxes and formed with depressed portions between said boxes, and a motor-supporting frame supported on said depressed portion of the side bars, substantiall 7as and for the purpose set forth.

7. In combination with the journal-boxes, yokes hun g thereon, hangers depending from said yokes, a truss-bar attached to the lower ends of the hangers, side bars attached to the yokes above the hangers and formed with central depressed portions united to the trussbar, body-supporting springs mounted on the side bars adjacent to the yokes, and a motorsupporting frame mounted on the depressed central portions of said side bars, substantially as described and shown.

In testimony whereof I have hereunto signed my name this 10th day of October, 1890.
