connecting the pairs of brake hangers together.

Another object is to position the live and dead levers of the brake so that they will be located substantially on the transverse center line of the truck through the center plate.

Another object comprises the novel manner of suspending the brake hangers from the side frame members and in line with the wheels.

The above and other objects and the novel features of the invention will be apparent from the following description taken in connection with the drawings in which,

- Figure 1' is a top plan view of one half of a truck embodying my invention; Fig. 2 isa side view partly in elevation and partly in section taken along the line 2 20f Fig.

1; Fig. 3 is an end view of the truck partly in elevation and partly in section; Fig. 4 is a transverse central section along the line 14 of Fig. 1; Fig. 5 is a plan view showing the brakerods and equalizing lever and part of the brake actuating apparatus to which the equalizing lever is connected; Fig. 6 is a perspective view of the tension device constructed according to my invention; Fig. 7 is a plan view of a brake hanger constructed. according to my invention; Figs. 8 and 9 are respectively an end elevation and central vertical section along the line 9-9 of Fig. 8 of a bracket for supporting one end of the tension device and also an inner brake hanger; Fig. 10 is a perspective View of a U-shaped link for suspending an inner brake hanger and the inner end of a tension device; Fig. 11 is a perspective view of a liner plate fitting between the link shown in Fig. 10 and the bracket shown in Figs. 8 and 9; Fig. 12 is a perspective view of a block which holds the link shown in Fig. 10 in place in the Patented Jan. 4, 1916.

bracket; Fig, 13 is a perspective viewof a lower flanges of the H-beam resting on brackets 24 of the pedestals and the top flanges of the H-beam resting on and secured to surfaces 25 on the top of the pedestal.

The pedestals 21 and 22 have projecting

portions

26 and 27 extending beyond the end of the H-beam or side frame member 23. The

ends

26, 27, of the pedestals are turned inwardly toward the longitudinal center line of the truck and near their ends are provided with

openings

26 and 27 to receive the upper ends of the outer brake hangers 28. As shown in Fig. 7 the upper end ofeach brake hanger is provided with a narrow part 29 which has a transverse pivot opening 30 through which the pivot pin 31 extends. The pivot pin rests on parts of the inturned

ends

26, 27, and pivotally supports the upper end of the outer brake hanger from the side frame members. At their lower ends the brake hangers 28 pivotally support the brake heads32 which carry the usual brake shoes to engage the tread of the wheels 17 and 18. The inturned ends of the

pedestals

26 and 27 have the

openings

26 and 27 thereof located substantially in line with the tread of the wheel, whereby the hangers 28 will depend in line with the wheel and support the brake heads and brake shoes in proper relation to the wheels. Brake heads 33 are pivoted to the lower ends of brake hangers 34 disposed between the wheels and the brakevheads 33 carry shoes which are capable of engaging the tread of the wheels 17 and 18 on the inner side and on the opposite side of the axles 1'5 and 16 respectively from the brake heads 32. The

brake hangers

34, 34, are similar in construction to the brake hangers 28 shown in Fig. 7 and depend from the side frame members in line with the wheels 17 and 18.

Brackets 35 such as are shown in Figs. 8 and 9 have portions 36 thereof fitting the web of the H-beams 23 on the inner side thereof and are riveted to the said webs. Each bracket has an angular extension 37 '42 of the link corresponding to the bend of the U fitting into the interior of the enlarged part38 through the bottom thereof while the limbs 43 depend downwardly, and have the eyes 44 formed in their lower ends. A. supporting block 45, such as is'shown in Fig. 11, has its top part concave as at 46 to receive the lower portion of the part 42 of the U- shaped link shown in Fig. 10. "A U-shaped liner plate 47, such as shown in Fig. 11 fits around the link shown in Fig. .10 and block shownin Fig. 11 and separates the said link and block from the interior surface of the enlargement 38 of the bracket and prevents the wear of the latter. The plate 47 has holes 48 and the block 45 has holes 49, which holes will register with the holes 39 of the bracket when the parts are assembled to receive the fastening bolts 50 which extend through all three elements and hold the block, plate and link in-place on the bracket.

Intermediate its ends each of thebrake hangers 28 and 34 has an enlarged boss 51 with a longitudinal opening 52. The outer and inner brake hangers 28 and 34 associated with each wheel of the truck are connected together by a 'frame such as shown in Fig. 6 composed of two

flat tension bars

53 and 54. A short distance from their ends each of the

tension bars

53 and 54 is thickened as at 55 and the thickened portion isbends 58 are so positioned, that they will lie flat against each other and each of the bends 58 is provided with an aperture 59 to receive a bolt 60; whereby the

bars

53 and 54 are irigidly secured together and thus form a frame which completely surrounds the bearing of brake hangers associated with each wheel. The bends 57 57, at each end of the frame thus formed extend across the. rear edges of the brake hangers.

-When assembled the eyes 56 of the bars 53 .and 54 register with the opening 52 of the brake hangers and with the eyes 44 of the link 41 and a single bolt or pin 61 passes through the registering holes in the beforementioned parts. The boss 51 of the brake hanger is considerably longer than the ordinary boss so as to eliminate bending action in the tension device or rods. The holes 56 in the outer end of the tension device register with the holes in the boss of the hangers 28 and the tension device and brake hanger are pivoted together by the bolts or pins 62. lft will be seen that the inner end of the tension device or the end nearest the bolster 63 is flexibly suspended from the side frame member and pivotally connected to the brake hanger 34 while the outer end is pivotally connected to the brake hanger 28. The tension device thus comprises a frame surrounding the brake hangers and the upper end of the wheel with which a pair of brake hangers is associated. The tension device thus also keeps the brake hangers .in line with the tread of the wheel.

At its upper end each inner brake hanger 34 is connected to an actuating'lever. The live brake lever 64' has a rod 65 pivoted thereto intermediate the ends of the lever and the oppositelend of the rod 65 is pivoted to the upper end of one of the brake hangers 34 while the dead lever 66 is connected by the rod 67 which rod 67 is pivoted to the upper end of the other brake hanger 34 on the same side of the truck.

at 68 to'fit on opposite sides of the upper end of the brake hanger. Each rod is also provided with a turn buckle 69 or other suitable device to take up wear. The lower end of the live lever 64 is pivotally connected to the lower end of the dead lever 66 by a link 70. The upper end of the dead lever 66 is pivotally connected to an anchor rod 71'which may be suitably connected to a part of the truck or a part of the car. The anchor rod 71 has a rearwardly extending portion. 72 extending beyond the pivot 76. The rearwardly extending portion 72 restsin a recess 74 at the upper end of a bracket75-which is fastened to the inner side of the web of the H-beam or side member 23. i

The links 77of the live levers 64 are guided in recesses at the upper ends of the brackets 75.

Referring to Fi s. 2 and 5, the links 77 of the live levers 64 are swiveled in the ends of brake rods 78 which extendalong the underside of the car'body and are pivoted at the end of a transversely extending equalizing lever 79 connected to and located near tially on the same transverse center lines However, instead of .using a lever passing,- through the center sills between the live levers, each live lever is connected by the link 77 and rod 7 8 tothe' end of the transverse equalizing lever 7 9 located at any convenient point, it being immaterial whether the equalizing lever 79 is on or near the transverse-center line of the truck through its pivot.

The operation of the devices will be apparent from the foregoing description and while I have described the truck in detail I do not wish to be limited to the devices shown and described as it is obvious that numerous changes may be made without departing from the spirit of the invention.
