Boele-TRUCK Fon ROLLING-STOCK.

SPECIFICATION forming part of Letters Patent N0. 757,927, dated April 19, 1904.

Application filed October 5,1903.

To all whom it 77mg/ concern..-

Beit known that I, HENRY ALBERT HOY, a subject of the King of Great Britain and Ireland, residing at Bolton, in the county of Lancaster, England, have invented Improvements in Bogie-Trucks for Rolling-Stock, of which the following is a specification.

This invention has reference to improvements in the construction of bogie-,trucks for rolling-stock whereby the load to be carried can be transmitted to the axles of the bogietruck in a more advantageous manner than heretofore and the transmission of .vibration from the axles of the truck to the body of the vehicle carried thereby can be reduced, the construction, moreover, being specially adapted for use with electric motors.

In a bogie-truck according to this invention the bogie-frame is supported through springs by longitudinal beams that are connected to vertically -movable supports, between which and the axle-boxes on the wheelaxles other springs are interposed. The bogieframe may be provided, as usual, with a bolster, to which the load is directly applied and which is supported on springs carried by a lower transverse beam suspended from the bogie-rame, so that in this case the load will be transmitted to the axles of the vehicle through three sets of vertically-acting springs.

Bogie-trucks according to this invention can be constructed in various forms, and the springs used therein maybe of any of the i kinds heretoforecommonly used,'such as coilsprings, laminated carriage-springs, or indiarubber springs, or partly of one kind and partly of another.

The invention consists in various novel features of construction and in combinations and arrangements of parts, all as hereinafteizmore particularly described,and pointed out in the claims. y l

IIn the accompanying illustrative drawings, Figure l shows partly in side elevation and partly in central longitudinal section, and Fig.

2 in plan, one construction of bogie-truck according to this invention, Fig. l also showing in side elevation a pivotal platform or support for carrying one end of the underframe and body of the vehicle with which the bogieserai No. 175,846. on model.)

. partly in end view and partly in cross-section,

on the line A A of Fig. l. Fig'. 4 is a crosssection of the bogie-truck and pivotal platform or support, taken on the lineB B of Fig. 1.

In the construction shown the bogie-t'rame comprises two longitudinal side members or sole-bars a of angle-section, each provided on its outer side with two horn-plates with axlebox guides c and a spring-holding bracket Z and connected together at the central portion of their length by two transverse members or transoms e and a top plate f. The ends of the two sole-bars are iirmly connected together by bent end pieces f. The transoms e comprise vertical plates of angle-section connected to the sole-bars a. by angle-irons g'and'spaced at a suitable distance apart to accommodate the bolster L, which is placed between them and provided with laterally-arranged vertical bearmg-piecesc, arranged to work between similar vertical bearing-pieces m, fixed on the transoms e.

The top plate f, which is curved at its opposite ends and extended at its sides in a longitudinal direction, so as to impart increased strength tothe bogie-frame, is formed with a central opening a and with two lateral openings 0, through which respectively extend the bogie center p and lateral bearing-pieces q, that are carried by the bolster h and upon which a center piece r and lateral bearingpieces s on a platform or support tto' be connected to the underframe or body of the vehicle to be carried respectively bear and move in the ordinary way.

/L is the pivot-pin for connecting the center pieces p and r together in the ordinary way. The bolster la. is of box-like section built up of transverse pieces of channel-iron and top .and bottom plates and is supported at its ends upon two pairs of coiled springs u, carried by a transverse beam c, which may, as shown, be oi' channel-section and is supported at its ends by longitudinal bars w, carried by the lower slotted ends l of two pairs of links 1, the upper ends l of which are jointed at 2 to the transoms e. The upper and lower ends oi' thesprings u are arranged to respectively IOO bear directly against bearing-plates 3 and 4, that are fixed to the lower sides of the bolster /i and transverse beam Q) and are provided with vertical extensions 5, that enter the said coiled springs and hold them in position laterally. The longitudinal bars w, that carry the ends of the transverse beam preferably engage in V-shape bearings 6, formed on the under side of the lower bearing-plates 4 and so arranged that the lower ends of the two pairs of links 1 are spaced farther apart than their upper ends, as heretofore usual:

Extending below each pair of axle-boxes 7, at opposite sides of the bogie-truck, is a longitudinal beam 8, provided with a pair of spring-holders 9, between which and the p spring-holding bracket d are placed a pair of coiled bearing-springs 10. The ends of each longitudinal beam 8 pass through the lower slotted ends of a pair of inverted-stirrupshaped supports 11, each of which extends upward between the opposite sides of an axlebox 7 and the adjacent axle-box guides c, each end of each beam being recessed at its lower side, as indicated at 12 in Fig. 1, and supported upon a V-shaped lug or bearing 13 on a yoke-piece 14, carried by the slotted lower ends of the corresponding support 11. Between the upper end of each support 11 and the top of the correspondingy axle-box 7 is placed a coiled spring 15, held in place llaterally by a socket-piece` 16 on the carrier and a socket 17 on the top of the axle-box. The lower ends of the horn-plates 7) at each side of the bogie-frame are connected together by a longitudinal rod or bar 18.

Bogie-trucks constructed as hereinbefore described are specially suitable for use as motor-bogies for electrically-propelled vehicles. For this purpose the casing 19, carrying the field-magnets of each electric motor, may, as indicated in Figs. 1, 2, and 3, be each journaled at one end upon one of the .wheel-axles 20 and be supported at the other end by means of lugs 21, that are carried by the casing 19 and bear upon springs 22, carried by bearingplates 23, held by bolts 24, suspended from the top-plate f of the bogie-truck, the motorarmature being geared to the axle in the usual way. The springs 22 may, as shown, vconveniently be of the kind known as Spencers No.
