JOHN A. BRILL AND GEORGE MARTIN BRILL, OF PHILADELPHIA, PENNSYLVANIA.

RAILWAY-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 433,932 dated August 12, 1890.

Application filed October 2, 1888- Serial No. 286,958- (No model.)

To 00% whom it may concern:

Be it known that we, JOHN A. BRILL and GEORGE MARTIN BRILL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Railway-Oar Trucks, of which the following is a specification.

Our invention has relation to independent rigid trucks for street-cars, or that form of trucks which, while rigidly secured to the car-body in contradistinction to pivoting the truck to the car-body, is removable therefrom, such as shown in Patent No. 425,653, granted to us April 15, 1890; and it has for its object a construction of independent truckframe wherein an electric or other motor may be mounted wholly upon the truck-frame, or partly thereon and partly upon the car-axles, wherein a light-weight and separate axle-box frame is provided for supporting the fenders, track-brushes, track brake-shoes, and sandboxes, and wherein a post form of pedestals may be used for the aXle-boxes, said truckframe being rigid and strong enough for all conditions of service and readily attachable to and detachable from the car-body.

Our invention accordingly consists of the combinations, constructions, and arrangements of parts, as hereinafter described in the specification, and pointed out in the claims, reference being had to the accompanying drawings, wherein Figure 1 is an elevation of an independent box-frame supports detached from the truck.

Fig. 5 is a detail elevation, partly in crosssection, of the truck-frame upper and lower chords and connections; and Fig. 6 is a sectional elevation showing another form of axlebox-frame support.

A represents the independent rigid or other truck-frame, composed of a top frame B,having side bars or chords b b, and end cross-bars b, and, if desired, intermediate cross-bars 19 which are suitably secured together and may be of any suitable material and of any suitable configuration in cross-section, as desired; but we prefer to make it of fiat bar-iron, the parts of which are forged together to provide a frame B in one piece when completed.

To frameB are secured the axle-box pedestals or supports G, which may be of any suitable kind or make; but we prefer that form of same known as the post form, and which is shown as consisting of grooved top plates 0, embracing the side bars or chords 1) of frame B, and having smooth openings near their ends for the passage of the upper ends of the posts 0, which post ends may be threaded and shouldered and screw into the sides I) offrame B, as indicated, and as fully shown, described, and claimed in another pending application filed by us of even date herewith, Serial No. 286,957. If desired, however, the posts 0 may be secured to the frame sides I) in any other suitable way.

The axle-boxes D are provided with springseats d, through which the posts 0' pass, and the latter are, if desired, provided with the main springs E and secondary top and bottom springs e and 6', respectively, and suitable caps or plates are interposed between said springs, as fully set forth in said other pending application, or any other suitable arrangement of springs between the axle-boxes and truck-frame may be substituted for that shown.

F F represent lower side bars or chords for the truck-frame, which chords may be connected to the axle-box pedestals, or the posts 0 of the latter may pass through and slide in openings in the chords F, as indicated. The end sections f of the chords F are preferably separate from the main secti'onsf, and are bolted thereto and to the frame B, so that the main sections f may be removable from the truck to admit of inserting the axle-boxes in position when building the truck and for dismounting the same for purposes of repairs or replacement. The main -.chord-sections f may be of any suitable form in cross-section; but we prefer to use the ordinary commercial angle-iron therefor and connect them by suitable corresponding or other cross-bars f which cross-bars are preferably arranged or located near the transverse center of the truck-frame or between the wheels to afford a rigid and strong foundation for wholly supporting an electric or other motor thereon, or for partly supportingit thereon and partly on the axles, as indicated at G, Fig. 1. If desired,'the cross-barsf may be connected to frame B and the motor secured thereto, as above described.

The lower chords F and the sides or chords b of frameB are near their transverse centers connected by V or other shaped brace-rods 1 and vertical pillars or posts2' 2', to prevent the truck-frame sagging or bending at its transverse middle, and for economy of construction We prefer to secure the brace-rods I and posts 2 to said chords and the cross-bars f to the lower chords F, as more plainly shown in Fig. 5, wherein are indicated clips h, having bent ends h secured to the lower side of the horizontal wingor top of the crossbars f which bent ends h are bolted, as indicated at 77. to the vertical sides of the chordsections f, and other corresponding clips 72 are bolted to the upper side of the top of the cross-bars f Said clips 72, and the horizontal or upper sides of the chord-sections fand the brace-rods I have openings through which' the posts 2' pass, and all of said parts are firmly bolted together and to the posts by means of collars 2" and nuts 2' on the lower ends of the posts 2'. The upper ends of the posts 2 are connected or secured to the frame chords or sides I), as shown, or otherwise, as desired. The ends 2' 2' of the brace-rods I may be secured to the frame sides or chords 1) or to the opposing ends of the pedestal castings or plates 0, as desired.

The brace-rods I may be in one piece or be composed of separate rods, as indicated in Fig. l of the drawings.

When the truck A is used on summer-cars, or those having an extreme length, brace or truss-rods K, between or joining the ends of the car and the chords or pedestal connecting bars F, are preferably employed, and the junction or coupling for the chords F and the brace-rods K may be of a construction as shown in our other aforesaid application, or as shown in the drawings, wherein either the chord-sections f or f" are formed with an angularly-arranged pin or foot f for engagement with or insertion into the bore of the end of the tubular brace-rod K, as shown more plainly in Fig. 2, the opposite end of said brace-rod sliding in tubular brackets 70, secured to the ends of the car and being eX- teriorly threaded and provided with j ain-n uts k (see Fig. 2,) so that said pin-couplingf between the braces K and chords F, may be made and disconnected by simply adjusting the jam-nuts 70 k? and sliding the brace-rod longitudinally to admit of easy removal of the truck from the car-body and of attachment thereto.

M represents the axle-box frame, which may be constructed of wood or partly of wood and iron, as desired, to make it of light weight, as it does not support the motor, and it has end fenders 222. Frame M may be secured rigidly to the axle-boxes or to depending or other located lugs d thereon, as indicated in Fig. 6, or it may have any suitable form of springlink or other support upon or connections with the axle-boxes. In Figs. 3 and t we have shown modified forms of said springsupports, wherein (1 represent vertically-arranged tubular lugs secured to or forming part of the axle-boxes. These lugs may be located between the springs E and the axleboXes forming an integral part of the springseats d, as indicated in Fig. 3, or located on the sides of the boxes near their outer ends, as illustrated in Fig. 4, or otherwise, as desired. Through these lugs (2 pass bolts (1 connected by flat metal bars d to which the frame M is secured in any suitable manner. The springs d for the bolts 61 may be arranged or located between the head of the bolts 61 and the top of lugs (P, as indicated to the left of Fig. 3, or be located within the bore of said lugs, as shown to the right of said figure.

The axle-box frame M, it will be observed, is independent of the truck-frame supporting the motor, and upon frame M may belocated the track-brushes, track brake-shoes, and sand-boxes, as fully set forth in our aforesaid other pending application, or, if desired, the sand-boxes may be secured to frame B or chords F.

If desired, the main section f of the lower chords F of the truck-frame may be made sectional, as indicated at f, Fig. 3, so that the ends of said sections bridging the axle-box pedestals may be removed Whenever it is desired to dismount the axle-boXes withoutnecessitating removal of the brace rods I and posts 2. So, too, if desired, elastic buffers or springs c may be placed on the posts 0', be-

tween the aXle-boxspring-seats d and the lower chords F, to compensate for or take up the jolting vibrations of the wheels on the rails.

As the novel features of our improvements may be greatly varied within the spirit of the invention, we do not confine ourselves to the same as shown and described.

hat we claim is- 1. The combination of the upper longitudinal chords adapted to be rigidly secured to the car-body, and having pedestals squared thereon, the lower longitudinal chords extending approximately from end to end of and connected to the upper chords, truss or brace rods and bolts connecting said upper and lower chords intermediate of the pedestals to form a truss, and cross-bars connecting said trusses, for the purpgse set forth.

2. The combination of a rectangular frame, the sides of which form the upper chords of trusses on the sides of a truck, and having the pedestals secured and squared thereon, the lower longitudinal chords connected together by cross-bars and extending from end to end of the upper chords, to Which they are secured, and truss or brace rods and bolts connecting said upper and lower chords intermediate of the pedestals, for the purpose set forth.
