CAR-TRUCK.

SPECIFICATION forming part of Letters' Patent No. 761,354, dated May 31, 1904.

Application filed 'lpril 4, 1900. Serial No. 11,561.` (Normodel.)

T a/ZZ whom, t may concern.: Beit known that we, JOHN A. BR'ILL and. WALTER S. ADAMS, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, (and whose post-ofiice'addresses are respectively care of the J. Gr. BrillOompany, same place,) have invented certain new and useful Improvements in Oar-Truclgs'of which the following is a speciiication.

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

Our invention has for its object to provide anefiicient truck and one economical in construction and maintenance.

The invention therefore resides inthe construction and combination of parts hereinafter described, and further pointed out-in the claims.

Reference is to be had to the accompanying drawings, `forming ypart hereof, wherein- Figure1is a side elevation of a car-truck and a portion of the car-body mounted thereon. Fig. 2 isa plan view thereof., Fig. 3 is a plan view of a portion of the truck, parts being broken away; and Fig. 4 is a partlybroken end View looking from` the right in Fig: 1. Similar numerals of reference. indicate corresponding parts in the'several views.

Our improved car-truck is constructed as follows: Y

At 1 are side bars connected with yokes2 3 at opp'osite'ends, the yokes 2 receiving the axle-boxes4 of the small or trailing wheels 5 and thel yokes 3 receiving the `axle-box l6 of the large or driving wheels 7 the truck-frame being resiliently supported 'upon' said axleboxes by springs 8 9 or in other well-known mannen From the yokes 3 arms 10 extend forwardly beyond the rims of the wheels? and are connected by a cross-bar 11, shown inv the form of a T-iron set in sockets in the ends of the arms 10 and suitably secured.

The side bars 1 are connected by a cross-bar 12, which maybe 'suitablysecured to said side bars, whereby the side bars arebraced laterally. From the yoke 3 an arm 13 extends forwardly above the arm 10, and 14 is a web that extends 4fromthe f ront edgeof yoke 3 upwardly and under the arm 13, whereby the parts 3 and 13 are stiffened and braced.

r1`he arm 13 is braced in connection with the cross-bar 11 by means of. a brace 15,v that is shown provided with a bifurcated end that receives the web 14, to which it is bolted or riveted, and the brace 15 is curved inwardly and its lower end is bent downwardly and secured by suitable means tothe cross-bar 11.

From the part of yoke 3 opposite the arm 13 an arm 16 extends rearwardly of the truck, and 17 is a web that extends from the yoke 3 along under .the arm 16 to strengthen and brace said parts. The arm 16 is braced in connection with the cross-bar 12 by means of a brace 18, shownbifurcated at its upper end and riveted or bolted to the web 17, its lowerl end being bent inwardly and suitably secured to bar 12. A

The arms 13 and 1,6 at their ends are raised above the central portion thereof, and at said ends they are widened out and provided with top depressions, in which the en d portions of a horizontally-disposed leaf -spring 19 lie.

vertically in the'depressions at vthe ends of arms 13 16, andthe side walls of said ends of the armsresistlateral movement of thel spring.

1 AIt will be seen that the connection of springr 19 with the 4truck isclose to a vertical kline passing .through the axle 7a of the drivingwheels 7 whereby a maximum-traction truck is produced.

The springs19, one at each side of the truck,

,are connected at their ends by cross-bars 23 .v 2 4, which' form a car-supporting means comprising a plurality of spaced members. These.

bars are shown in T form inc'ross-section (see Fig. 1) and may be connected withthe springs 19 in suitable manner. We have shown the bars provided near their ends with clips or socket-pieces 25 26, whose recesses or sockets follow the outline of the bars 23 24 (see Fig. 1) andare secured thereto, as by bolts passing through the depending webs of said clips and the depending web oi' the bar. From the upper surface of the clips 25 26 project eyes 25 26, arranged in pairs (see Fig. 4) and receiving between them a pin 27 28, upon which the corresponding end oi' spring 19 is coiled. Thus the cross-bars are pivotally connected with the ends ot' spring 19 to allow 'for vertical movement of the bolster relatively to the spring, and as this bolster extends across the truck it serves as a support for the carbody to resiliently support the same from the springs 19, the bars or bolsters being located eccentrically of the Wheel-base center of the truck, the bar 23 being located adjacent the axle of the driving-wheels and adjacent to which wheels the pivotal center of the truck is located, thereby providing an eccentricallypivoted truck and the imposition of the carload thereon adjacent the driving-wheels, both desirable features in trucks of this class. As a specific means of carrying out the foregoing the bar or bolster 23 is located outside the wheel-base.

The cross-bars 23 24 are provided with bearing-plates 29 30, `which are secured centrally upon the top surface thereof, upon which rest bearing- plates 29a 30, that are carried by the l car-body, the latter plates being curved on an are derived from the pivotal center ofthe cartruck. (See Fig. 2.) The plates 29 30L may be secured to the car-body in any suitable manner, and they are shown secured toand beneath cross sills or beams 31 32 of the carinner face of the sill 33, and the ends are bent sidewise and lie against the corresponding portion of sills 31 32, to which said ends are suitably secured, all as shown in Fig. 2.

To assist in holding the small wheels 5 down upon the track, or, in other words, to keep them from jumping, we provide the following arrangement: The cross-bar 12 is shown bent outwardly at its center portion 12u toward the axle 51L of the small wheels, (see Fig. 3,) and upon said bent portion rests a spring'- eup 40, through which a guide-rod 41 passes, the spring-cup being retained upon the bar 12 by a strap or the like 42, and 43 is a spring coiled around the rod 41 and resting upon cup 40. Beneath the head 41 of rod 40 is a spring-cap 44, resting upon spring 43, whereby rod 41 is sustained by spring 43, and said spring resists the downward movement ot' said rod. Upon the head 41a of rod 41 a plunger "lateral pivotal movement.

or wear-plate 45 rests, and this is guided in a bushing or bearing 46, carried by cross-bar 24. A bearing-plate 47, carried by the carbody, rests upon plunger 45, (see Fig. 4,) and the under surface of this plate is shown eamlike, or, in other words, it diverges downwardly and outwardly from its central point 47 and this central point or the high part ot the plate 47 is so located that when the truck is in proper alinement with the car-body the plunger 45 will rest therein. (See Fig. 4.) Thus if the small-wheel end of the truck tends to rise from the track it will meet the resistance of the parts 41 43 45 47 and the car-body, and as the truck swivels under the car-body the cam-surfaces ofthe wear-plate 47 will cause spring 43 to exert increased pressure upon the cross-bar 12 to further assist in preventing the small wheels from jumping from the track.

We have shown improved means for ad raw ing connection between the truck and the earbody, which are arranged asfollows: At 50 is a draw-bar connected with cross-bar 23 and with a sill or bar 51 ot' the car-body. This draw-bar is shown as bifurcated or provided with two arms attached to cross-bar 23, as by rivets, bolts, or the like, and at its opposite end it is provided with a head portion 50, that has an aperture through which a drawing-pin 52 passes, said pin being connected with the part 51 of the car-body. The head portion 50a of the draw-bar is shown as extending horizontally beneath the car-body, and the arms of the draw-barare shown as bent downwardly and forwardly toward the cross-bar 23, whereby the pivot 52 is elevated above said cross-bar. The arrangement we have shown for supporting thepivot 52 comprises the sill or cross-bar 51, having its ends 51 bent downwardly and attached to the intermediate longitudinal sills 33 oi the car-body, (see Fig. 4,) and 53 is a strap secured to the under side of sill or bar 51 and bent downwardly at its central portion 53, forming a space 54, in which the head 50ll of the drawbar is located (see Fig. 4) and wherein it has Thus it will be seen that as the truck is propelled it will draw the car-body through the medium oi the drawbar, or vice versa, and that as the car-body is supported upon the cross-bar`23 and the drawbar 50 is also connected to cross-bar 23 and to the car-body the vertical movements oi the body upon springs 19 will be coextcnsive with the vertical movement of the draw-bar, and thus no undue strain will be applied tothe draw-bar through the movements oie the carbody.
