CAR-TRUCK.

rammed May 22, 1906.

Application filed April 4, 1900. Serial No. 11.562.

To all whom it naa/y concern:

Be it known that we, JOHN A. BRILL and WALTER S. ADAMS, citizens of the United States, and residents of the city and county of Philadelphia, State of Pennsylvania, (whose post-office addresses are respectively care of J. G. Brill Company, same place,) have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

Our invention relates to certain improvements in car-trucks generally, and more especially to the maximum-traction class of pivotal trucks.

Our invention has for its obj ect to provide.

an eilicient truck and one economical in construction and maintenance.

The invention consists, therefore, in the construction and combination oi parts hereinafter described, and further pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a side elevation of a car-truck and a portion of a car-body embodying our invention. Fig'. 2 is an end elevation thereof looking from the left in Fig. 1, part of the car-body being in section. Fig. 3 is an end view looking from the right in Fig. 1, part of the truck being broken away and part of the car-body being in section. Fig. 4 is a detail plan View of a portion of the car-truck, and Fig. 5 is a plan view showing the sills of the car-body and a portion of the truck beneath the same.

Similar numerals of reference indicate corresponding parts in the several views.

The car-truck we have shown comprises side bars 1, axle-box yokes 2 3, connected therewith, arms 4, extending forwardly from the yokes 2, a cross-bar 5, connecting the side bars 1 near the small wheels 6, and a crossbar 7, connecting the arms 4 in advance of the large or driving wheels 8. The axleboxes 8a 6a resiliently support the side bars through the springs 1a, located in recesses in the yokes, and which springs rest upon ears extending from the axle-boxes. At the unction of the arms 4 with the yokes 2 is a web 2a, that 4is cast integral with said parts and serves to strengthen the same, and at the junction of' the side bar 1 with the yoke 2 is a web 2b, similarly arranged and for the same purposes as web 2a. 3"L is a web that extends over the top of axle-box 3 and joins the side bar 1 and the projecting portion 3b of said yoke, whereby those parts are stiifened. In order to carry the cross-bar 5 well back toward the axle 6b of wheels 6, while at the saine time permitting the wheels 6 to clear said cross-bar, the latter is bent at 5rL in line with said wheels and is also shown bent at 5b transversely to its length and in line with the side bars 1, to which the part 5b is bolted. (See Fig. 4.)

The car-body is resiliently supported from the cross-bars 5 7 of the truck, and the arrangements we have shown for this purpose are as follows: 10 represents supports or uprights secured upon the cross-bars 7 near opposite sides of the truck and carrying at their upper ends a pivot or pin 11, to which are pivotally connected links 12, arranged in pairs, spaced apart, and having a pivot-pin 13 at the free ends around which the corresponding ends of a semi-elliptic spring 14 are coiled, said spring being bowed upwardly from the pivots 13, as shown in Fig. 2. To the crossbars 5 a spring 15 is similarly connected, wherein 16represents supports secured to said crossbar and provided with a or pin pivot 17, upon which links 18, arranged in pairs and spaced apart, are mounted, and at the free ends of said links is a pin 19, upon'which the end of spring 15 is coiled, as shown in Fig. 3. Thus it will be seen that the springs 14 and 15 are movably suspendedy at their ends from the cross-bars 5 and 7, and it will be understood that as more or less weight is applied to said springs and they lengthen or contract the links 12 and 18 will swing on their pivots, and thus accommodate for the movement of said springs, the Springs thus havifr`suspension-supports that are adapted to havo a sub stantially vertical movement.

The spring 14 supports a bolster 20, that extends transversely ci the truck and comprises a cross-piece 2Oa and opposed centrally-depressed depending webs 2Gb, that are spaced apart and` receive the spring 14 be.-,

tween them. (See Fig. 1.) The cross part 20*JL of the bolster rests upon the spring 14, and 21 represents cross pins or bolts passing underneath the spring and suitably secured to the IOO ' car-body 25.

ends the bolster 2O carries side bearingsA 26,

depending webs of the bolster, whereby the spring is firmly held in the bolster, the strap 14L of the spring vbeing shown located between the pins or bolts 21. fr (See Fig. 2.) At the central portion of the'bolster 20 it is provided with a vertical slot 22, (see Fig. 2,) and at the sides of this slot the bolster is shown provided with vertically-extending strengthening-webs 20C. There is a slot 22 in each depending web of the bolster 20, which slots are in alinement, and the ortions of the bolster at the sides of sai slot straddle the cross-bar 7 and projections 23 on the crossbars, (see Fig. 2,) whereby the bolster is free to vibrate vertically relatively to said crossbar, and yet the projection 23 in conjunction with the walls of the slot 22 prevent lateral movement of the bolster-relatively to said cross-bar.

The bolster 20 supports a superposed carbody, and its top surface at its central portionis flat in the form of a wear-plate and receives upon it a central bearing 24, carried by the car-body, being shown inthe form of a plate attached to intermediate sills vof the (See Fig. 5.) At its outer upon which rest wear-plates 27, that are carried by the car-body. These parts 26 and 27 serve to resist the rolling motion of the carv body upon the truck, and the center bearing 24 is in an arc derived from the pivotal center of the truck. 1

From the spring 15 a yoke 28 depends. This yoke is shown composed of a transverse top piece 28av with depending webs 28h, that straddle the spring 15 and also straddle the cross-bar 5 of the truck. (See Figs. 1 and 3.) The depending webs of this yoke also have vertical slots 29, that receive between them projections 30, extending from opposite sides' ofthe cross-bar 5. (See Fig. 3.) The top portion 28a of web 28 rests upon spring 15, being shown as overlying the strap 15ZL thereof,'and` bolts or the like 31 pass through the webs'28b beneath the spring 15, whereby the parts are firmly securedtogether. It will thus be seen that the yoke 28 is suspended from spring 15 and is prevented from having lateral movement relatively to the car-truck by the projection 3'0 of cross-bar 5, and thus the sprin 15"is kept from moving laterally of the ik bodily.

The yoke 28 receives part of the weight of thecar-body, and the spring 15 and this yoke also serve to keep the small wheels 6 from jumping from the track. For this purpose we have shown a wear-piece 32, secured upon the top of yoke 28 and in line with a wearplate 33, carried by a cross-sill of the carody. This plate 33 is shown cam-like on its wearing or under surface-that is to say,

lfrom. its central point 33a its under surface extends downwardly and outwardly at 34 in opposite directions transversely of the car and in such position as to ride upon the wear-piece 32. (See Fig. 3.) From this it will be understood that as the car-truck swivels beneath the car-body the wear-plate 33 will press upon the part 32 with more or less pressure, and the spring 15, being interosed between the truck and said wear-plate,

will tend not only to support the body from the truck, but to keep the truck-wheels from rising from the track, and the more the truck swivels beneath the car-body the greater will be the pressure of the camplate 33 upon spring 15.

We have provided a drawing connection between the car-body and the truck which is arranged as follows: 35 is a draw-bar, shown bifurcated or provided with two arms that vextend from a head portion 36 forwardly to the bolster 20, to which they are secured.-

(SeeFigs. 1 and 4.) The head 36 of this= draw-bar is pivotally connected with the carbody, as by a pivot 37, connected with a cross v sill or beam 38 of the car-body, the head 36 having a suitable aperture to receive the pivot 37, and this pivot is shown located over the axle 81D of the drive-wheels 8. As

the pivot of the draw-bar 35 is above the plane of the top of bolster 20, the draw-bar 35 from its head 36lextends downwardly and forwardly to a point 35, whence it extends horizontally at 35b to the top of the bolster.

We have shown improved means for bracing the carebody transversely, which are arranged as follows: 40 is a beam extending horizontally between the side sills 41 of the car-body, and at its ends it is bent downwardly andoutwardly at 40a beneath the sills 41, and at its ends it is provided with eyes 40". The beam 40 maybe in the form of a channelbeam having its channel facing upwardly, as shown in dotted lines in Fig. 1. 42 represents tie-rods which are connected with the eyes 4()b of the beam 40 and converge from said eyes to a point midway in the central longitudinal line of the car-body, where their centrally-bent portions are received in holding ieces or stays 43, secured to a crosssill 44 o the car-body. (See Figs. 1 and 3.) 1t will be understood that' as the tie-rods 42 are connected to the eyes 40b by nuts more or less tension between the parts 40 and 42 may be applied, and as the rods are hung from the car-body at the central points 43 a strong -of the truck and movably supported by a cross-bar, with a bolster mounted upon said IOC IIO
