RAILWAY TRUCK STRUCTURE Filed April 21, 1930 4 Sheets-Sheet 4 Patented Sept. 6, 1932 UNITED STATES PATENT OFFICE KARL S. HOWARD AND -EDWIN O. JACKSON, OF ST. LOUIS, MISSOURI, ASSIGNORS TO GENERAL STEEL CASTINGS CORPORATION, OF GRANITE CITY, ILLINOIS, A GOR- IORATION OF DELAWARE RAILWAY TRUCK. STRUCTURE Application filed April 21,

Our invention relates to railway rolling stock and consists in a novel railway truck structure and more particularly in the combination of a fluid reservoir and fluid brake cylinder with the truck frame.

Customarily, reservoirs and brake cylinders have been completed separately from the truck frame structure of the vehicle and have been provided with flanges adapted to be attached to brackets on the vehicles framing and by which the reservoirs and cylinders have been secured in place. This construction requires frequent and detailed inspection to see that the rivets or bolts are tight to insure the maintenance of proper assembly. Such construction is likely to result in unnecessary play in the brake rigging since the brake cylinder issecured to a part that moves in relation to the truck on which the brake beams and their actuating levers are mounted.

The main objects of our invention are to secure rigidity, to decrease maintenance attention and delays and to effect certain other economies and advantages by making the reservoir integral with the side frames of the truck, and by making the brake cylinder integral with a transverse element of the truck frame and, preferably, with a longitudinal 30 member of the frame.

We also desire to form either the brake cylinder pressure'head or the non-pressure head or the non-pressure head and housing or pressure head and housing or housing integral with the truck frame.

Other detail objects of our invention will appear from a reading ofithe following de-- scription of the device with reference to the accompanying drawings of the same.

' The reservoir and brake cylinder elements may be formed integrally with the truck framing by casting or by any combination of the methods of casting, welding, forging, etc.

In the accompanying drawings which illustrate our invention- Figure 1 is a top view of an engine truck embodying a preferred form of our invention showlng the reservoir integral with the side frames of the truck and showing the brake cylinder integral with the end sill and 1930.

Figure 12 is a vertical section, taken on the line 1212 of Figure 10.

Figure 13 is a section taken on line 1313 of Figure 1.

In the structures shown in the first three figures, the side frames of the truck are indicated at 1 and are integrally connected by

end transoms

2 and 3 and center transoms 4. Between the transoms 4, is mounted the bolster 5, carrying the center plate structure '6. The truck frame is mounted in the conventional manner on wheels 7 by means of equalizers 50 resting on axle boxes in the pedestal jaws 8.

The truck frame in this form of our invention has a longitudinal member 9 extending between one end transom 2 andthe 5, nearer center transom 4. Member 9 has one portion 10 extending horizontally to the top of transom 4 slightly below the level of the top of end transom 2 and another portionll extending downwardly and centrally to the bottom of transom 4. At the juncture of portions 10 and 11, the member 9 is continued upwardly and outwardly to merge with end transom 2.

Further reinforcement is given to the truck frame by the reservoir member 12 which is integrally joined to the side frames 1 and is disposed transversely with respect ,to the truck. Preferably, this reservoir is of substantially cylindrical shape, but if desirable may be made of oval, rectangular or other cross section. The reservoir has an opening A to facilitate casting. This opening is closed by a cap plate which is welded over the same after the casting operation is completed.

Reservoir 12 is integrally joined to but spaced from the pedestal 'aws 8 of the side frames 1 by means of the iagonal flanges 13 at the ends of the reservoir and is spaced be tween the top and bottom levels of the frames.

This disposition of flanges 13 enables the equalizer bars 50 to extend over flanges 13 and between the ends of the reservoir 12 and pedestal jaws 8 to a point over the axle boxes 38.

c Brake cylinder housing 14 is integral with and above the end transom 2 and longitudinal member 9, placing the cylinder above the mean top level of the truck frame. Nonpressure head 15 is formed integral with the cylinder housing 14.

To further. carry out the main objects of our invention, as much of the brake rigging mounting structure as possible is made integral with the main parts of the frame. Integral brake hanger brackets 16 extend outwardly and downwardly from the top of the side frames 1. Brake rigging brackets 17 are integral with the bottom of reservoir 12.

These latter brackets together with projections 18 on the transverse angular member 19 are adapted to pivotally hold a portion 190.

of the brake rigging. Member19 is integral with the pedestal jaws 8 on the opposite sides of the truck frame and also is integral with the reservoir member 12. Upper portion 10 of member 9 is vertically divided as shown at 20 to receive a brake rigging arm 21 which is pivotally held in position in the transom by means of pin 22 extending through the sides of the member 9. The brackets referred to are for the mounting of a conventional braking system.

In the modification illustrated'in Figures 4, 5 and 6, the cylinder housing 25 and pressure head 26 are shown integral with the channel shaped end sill 28 and the cylinder extends inwardly'therefrom, the side of the cylinder merging with the top flange 27 of the end sill. The end sill 28 is substantially below the level of the side frame 29, bringing the housing 25 and pressure head 26 of the brake cylinder below the level of the top of the truck frame. 5

.In the modification illustrated in Figures 7, 8 and 9, a brake cylinder is' shown integral with the center transom 30, the upper surface of the housing 31 of the cylinder being substantially in the plane of the top surface of the transom, while the lower' surface of the housing 31 is substantially below the level of that portion of the bottom surface of the transom at the sides of the transoms. The cylinder is also integral with longitudinal members32 and 33 which extend outwardly from transom 30 to the end transom 34.

In the modification illustrated in Figures 10, 11 and 12, we show our invention applied to a trailer truck for a' locomotive 1n which brake cylinderhousing 35 and nonpressure head 36 are shown formed integral with the rear transom 37 of the truck frame.

We direct attention to our copending application, Serial Number 446,125, filed pril 21, 1930, which illustrates other truck structures having brake cylinder elements integral with the truck frame.

Some. features of our inventionmay be included in any structure in which' instead of the entire reservoir or cylinder bein integral with the frame as described a ove, suitable brackets for supporting the reservoiror cylinder are integral with the truck frame.

Other details in the structure of our invention may be modified without departing from the spirit thereof and we contemplate the exclusive use of all modifications that come within the scope of our claims.
