CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 458,749, dated September 1, 1891.

Application filed October 30, 1890. Serial No. 369,786. (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 Oar-Trucks, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to provide to a car-truck which shall be simple and inexpensive in construction and at the same time possess the requisite stability to resist the various strains it is subjected to, and shall also be equipped with body-supporting springs of I 5 superior efficiency and with a motor-hanger which allows the heel of the motor sufficient lateral play to obviate cramping the motorframe when the truck is traversing a curve in the road; and to that end it consistsin the improved construction and combination of parts hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure l isa side elevation of a car-truck embodying my im- 2 5 provements. Fig. 2 is a top plan view of one of the end portions of said truck. Fig. is a horizontal transverse section on line as at, Fig. 1. Fig. 4 is a vertical transverse section on line y y, Fig. 1. Fig. 5 is an end view of 3c the truck-frame. Fig. 6 is an enlarged detached side view of the spring-supporting base. Fig. 7 is a vertical transverse section of the car-spring and its attachments. Fig. 8 is an enlarged side view of one of the end 5 portions of a truck embodyinga modification of my invention. Fig. 9 isa front view of the stay of the car-body shown in Fig. 8, and Fig. 10 is an enlarged side view of the stay shown in Figs. 1 and 5. 0 Similar letters of reference indicate corre sponding parts.

Zlrepresent the journal-boxes containing the bearings for the axlesAof the car-wheels D D. Upon said j ournal-boxes are hung the yokes h 72., which embrace the sides of said boxes and extend below the same. To the opposite sides of the lower ends of the yokes are bolted or riveted the longitudinal side bars B B, which are preferably straight from end to end and extend across the under side of the journal-boxes and under the end portions of the car-body. The end portions of the bars B B receive additional supports by means of braces B B, secured to the top portions of the yokes and inclined to the end portions of the aforesaid bars and firmly attached thereto.

The car body is supported by springs mounted on the bars B B at the central and end portions thereof, as shown in Fig. 1 of the drawings. To prevent the car-body from shifting longitudinally over the truck, pedestals R B. are secured to the car-body or to the longitudinal topbar F of the truck, to which bar the car-body is fastened, said pedestals embracing the sides of the journal-boxes Z Z in the usual manner. For supporting the carbody elastically vertically I employ compound springs, each composed of a spiral steel spring 5 and a rubber cushion f, which are held in place and secured to the truck-frame by the following devices, to wit:

Upon the longitudinal barsB B is mounted the spring-supporting base 6, formed with a depending web 0, which is inserted between the aforesaid bars and fastened by bolts or rivets passing transversely through the same. The top of the said base is cup-shaped, and a perforation extends vertically through the center of the base. of the base is seated axially vertically the spiral spring 5-, and upon the top ofthe latter is placed the cap e, which is perforatedvertically in its center and provided with a recess c in its under side to receive the end of 85 the spiral spring. The top of the said cap is also formed with a recess 6", in which is seated the soft-rubber cushion f, which is also perforated vertically in its center.

To the under side of the car-body or top 0 bar F of the truck is firmly secured a stirrup a, which is formed with the perforated crossplate b and with the side opening 0 above said plate.

Through the perforations of the base e, cap 9 e, cushion f, and cross-plate b of the stirrup and through the axis of the spiral spring passes the bolt 2', which is inserted from beneath the base c and is provided with a head on its lower end and with a nut on its upper I00 Upon the cup-shaped top end, which latter protrudes through the crossplate I). The side opening 0 in the stirrup allows the nut to be introduced and applied to the bolt.

To relieve the pedestals R from excessive lateral strain, I rigidly attach to the car-body or to the bar F stout posts g g,-Which depend therefrom and pass with their lower ends movably vertically between the bars B B and vertical guides 76 7t, secured to said bars in front and rear of each post, which guides may be either of the form of blocks firmly attached to the bars B B, as shown in Figs. 8 and 9 of the drawings, or of the form of rollers pivoted to said bars, as represented in Figs. 1, 5, and 10 of the drawings. Said posts are further sustained by lateral braces g g, fastened to the under side'of thecar-hody and connected to the pendent portions of the posts,as :illustrated in Figs. 5and 9 of the drawings.

When the described truck is to be used on a car designed to be propelled by an electric.

motormounted on the truck, I connect tothe truck-frame the following hanger or support for the heel-0f the motor.

Upon the two sets of bars B B on opposite sides of the truck I mount pedestals PR:

formed ;at their bases with downwardly-extending tenons t, which pass, respectively, be-

tween the bars B B of each set and are fast ened thereto by bolts orrivets passing trans- 'versely through them, as-shown in Fig. 4 of the drawings. Each of said pedestals has'an openingextending vertically through it, and

insaidopening is ahanger i, pivoted to the;

tudinal bars B B, secured to said yolres, the

upper end of the pedestal.

To opposite sides of the hangers of the two pedestals are pivotally connected two cross-.

bars 0 O, to which the heel of the motor is connected by any suitable or well-known coupling, not'necessary to be here illustrated.

The bars CO, asshown in Figs of the draW-' ings, are perforated'at r for the attachment of the""Short motor.

I represents the lifeguard-which is at-. tached directly to the ends of the side bars Having described my invention, what I claim asnew, and desire toseoure by Letters Patent, is

and guides k, attached to said bars in frontand rear of each post, substantially as described and shown.

2. In combination with the truck, car-body, anditssupporting-sprin g, the stirrup a, formed with the perforated cross-plate b and side opening 0 above said cross-plate, the bolt (1, extending axially through the spring and through the truck-frame and plate b of .the stirrup, and the nut 02, applied to the end of said bolt above the said cross-plate, substantially as described andshown.

3. In combination with the truck'and carbody, the base e,.-seated-on the =truck=frame and perforated in its center, thespira'l spring 3, seated on said base, the'capriflseatedwupon the upper end ofsaidspringandformedwith the recess e""in its top, the stirrup a,zformed with the perforated cross-plate b, sideopening ,c,.and recess 0' in its underside, the-rubber cushion f, interposed between thestirrup and cap and seated in the recesses thereof, the bolt 01, passing-vertically throu ghthe base 6, spring 3, cap e, cushion f, and crossplate b, and the nut n, applied to the end of the bolt above said cross-plate, substantially as described and shown.

4. In combination with the journal-boxes, the yokes h h, hung on said b.oxes,-the longipedest-als zP P, mounted on said bar-sat :opposite sides of'the truck, the hangers d1, pivoted to said pedestals, the cross-bars0 .O, pivoted to the saidhangers,'andacou'pling connecting the heel of the motor to said :crossbars, substantially as described and-shown.

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