Specification of Letters Patent.

Patented Oct. 12, 1909.

Application filed. December 29, 1908. Serial No. 469,740.

To all whom it may concern:

Be it known that I. JosIAH H. SMrrrna citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Trucks, of which the following is a specification.

My invention relates to improvements in trucks, particularly designed for use on suspension railways, the object of the invention being to providean extremely strong support for the car, which will allow of a pivotal movement of the truck and overcome swinging movement of the car.

A further obj ectA is to provide an improved construction of bolster having spring mounting at its ends on the side frames of the truck, and made at its center with an integral journal, constituting the car support. n

A further object is to provide an improved construction of bolster having a central car supporting journal and enlarged rubbing surface to contact with rubbing surfaces on car supporting hangers, and prevent swinging of the car.

A further object is to provide an improved construction of tie-bar, which latter affords mounting for auxiliary wheels normally out of contact with the tracks, but in position to assist in supporting the truck in the event of injury to a wheel or axle, and hence prevent falling of the truck.

With these and other objects in view, the invention consists in certain novely features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a top plan view illustrating my improvements. Fig. 2, is a view in side elevation partly in section. Fig. 3, is a view in cross section on the line 3-3 of F 2, and, Fig. 4, is a view in end elevation.

prevent lateral movement and buckling of the side frames.

U-bolts 8 straddle the frames 1, at their lower ends, project through openings in spring plates 9, and nuts 10 are screwed on to the bolts below the plates 9. Coiled springs 11 are supported on the plates 9 and bear upwardly against spring plates 12. Bolts 13 having their upper ends countersunk in the plates 12, extend downwardly ythrough the coiled springs 11 and plates 9, and through openings in the ends of semielliptical springs 14, and nuts 15 are secured on the lower ends of said bolts 13 to eifectnally clamp the ends of the springs 14.

16, 1G, represent tie-bars, which are in the form of flanged castings, having boxes 17 at their ends, secured to the lower ends of the yoke portions 2 of arms 1, by means of bolts 18, and rigidly connect the lower ends of said yokes, constituting a fixed portion of the side frames. These tie-bars are provided at their center with bearings 19, in which the axle stubs 20, of auxiliary wheels 2l, are mounted, and these auxiliary wheels 21 are preferably positioned, so as to be just above the rails and out of contact therewith, but in such close relation to the track, that should one of the axles, or one of the wheels become broken, the auxiliary wheels will come into instant engagement with the track,

supporting the truck, and prevent the truck leaving the track.

22 represent-s my improved bolster, which comprises a single integral casting, having its ends supported at the center of the semielliptical springs 14, and secured thereto by means of U-bolts 23. These U-bolts 23, there being two employed at each end of the bolster, are each made with one member longer than the other, the shorter member only extending up through block 24 on top 'of the springs, and secured by nuts 25 E while the longer members only of said bolts,

l extend'up through the blocks 24, and also 1, 1, represent the side frames provided with the ordinary yokes 2, receiving the journal box 3, supported on the axles 4, the i latter secured to the ordinary wheels 5. f These frames 1, 1, are connected at their g center by angle iron transoms `6 secured to the frames by means of the angle brackets 7, the latter', securely riveted to the tranl through the bolster ends, and are secured by nuts 26. It will thus be seen that the bolts 23 secure the bolster on the springs, and the several sections of the latter together, and that only one member of each U-bolt extends through the bolster, which renders it necessary to remove but four nuts 26 to disconnect the bolster from the truck, and not disturb the other elements of the truck in the slightest. The intermediate portion of said bolster 22 is east hollow and enlarged forming a flat rubbing plate 27, and at the center the bolster is made with a tubular post 28 which connects the upper member of the bolster and the rubbing plate to form a strong and durable structure. Below the rubbing plate at the center of the bolster, and in line with the post 28, a tubular depending integral journal 29 is provided on the bolster, and is made with an annular enlargement or head 30 at its lower end. This journal 29 is adapted to receive the ear hanger sections 3l thereon, said hanger sections being made with semi-cylindrical bearings at their meeting ends, to encompass the journal, and provided with flanges 32 at their side edges, which latter are securely clamped by bolts 33, to clamp the hanger around the journal, and afford a pivotal mounting thereon.

It will be observed that the head is of appreciable greater diameter than the bearing in the hanger section, and hence there is no possibility of the hanger falling from the journal.

The hanger sections 3l are both provided with enlargements 34 constituting rubbing faces to rub against the enlargements 27 and prevent lateral swinging movement of the hanger sections on the bolster, and compel the springs of the truck to take up all such swinging tendency. rllhe hanger sections 31 may be constructed in a great many ways, those shown straddling the ear body and secured by angle brackets 3G to an I- beam `37 extending across the upper portion of the car. The eXtreme ends of the hanger sections are shown secured by nut-s' 38 to upright bars or rods in the car body.

By constructing improvements as above described, I provide a construction of bolster and supporting means for the car body, which will prevent any independent swinging movement of the car body on the bolster, and which will absolutely prevent any separation of the ear body from the bolster, but permit a suthcient pivotal connection between them to compensate for the curvatures of the track, and the pivotal movement of the truck, and I further provide an improved construction which can be readily assembled, which will embody the maximum of strength and durability with the mini mum of weight, and which will absolutely prevent accident, due to a broken wheel or axle.

A great many slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.
