My invention relates to railway rolling stock and consists in a novel locomotive frame-and air reservoir construction. V

The main object of my invention is to con-. struct an air reservoir adapted to be, placed longitudinally of the locomotive between and connected to the sideframes thereof, such" reservoir, and its connections to the side frames being adapted to form a substantial. reinforcement for'the frames and tov share the longitudinal forces imposed on said. frames. The reservoir may beformed: of aplurality of members each of arcuate cross section and flanged to engage the adjacent member ormembe'rs; l v

In. the construction shown in and 3,'the,reservoircomprises two main portions 1 and 2 extending longitudinally of the.

locomotive. The lower or body portion 1 re-- sembles a trough in outline and the upper portlon 2 resembles an inverted trough fitting over portion ,1. Preferably, each of these portions comprises a casting which can be made of any desired width, length and thickness to capacity.

1 The lower portion 1: is provided with integral brackets 3 and A for.- attachment to the locomotive side'frames 5 Each bracket 4 Figures 1, 2

provide required strength and inoludes'a'downward extension 6 which may i be bolted or leg7.- i v Suitable vertical ribs 8 extend transversely and exteriorly of the-reservoir body be tween brackets 3 and/1, reinforcingv the same 7 and the body of the reservoirportion and also extending between and reinforcing horizontal flanges 9 extending around the upper to be joined with corresponding flanges 10 formed'on the lower edges of the upper por- The lower reservoir portion l is preferably 1 provided with integral expansion plate brackets 12 which extend-upwardly beyond the connecting flanges 9 and 10 and the upper reservoir portion is provided with integral brackets 13' for holding radiating pipes 14. v. V

A relativelydeep transverse web 15 braces the vertical brackets 6 throughout their depth and serves as abrace forthe cor'respondingpedestals. This web is provided with a horizontal flange 16 at its lower edge the section. V v

-.The two reservoir portions 1 andg2, may be united by any suitable means, such as and with suitable openings 17 for lightening otherwise secured to the pedestal V bolting, riveting or welding and, when c'ompletely assembled with the locomotive frames, constitute a; substantial part ofthe framing thereby greatly reinforcing the sides and, if desired, making it possible to use side frames of less weight than would be practical with the ordinary framing with the reservoir mounted on the exterior of the boiler shell.

The structure is adapted. to transmit forces longitudinally, vertically or transversely and by forming the expansion sheet brackets 12,

radiating pipe brackets 13, brake hanger brackets 18 and connecting members 6 integral with the reservoir a large amount of fitting and assembling work is eliminated which is usually required for the application of these and similar parts to the locomotive frame.

In the structure illustrated in Figure 4, the upper portion 19 of the reservoir has the expansion plate brackets 20 integral therewith and extending around the exterior of the reservoir section, as indicated at 21, to form a substantial reinforcement of the body of the reservoir. The brake hanger lugs 22 are integral with the lower reservoir section 23 as in the preferred construction.

In the construction shown in Figure 5-, the brake hanger lug 24 and the expansion plate bracket 25 are both formed integrally with the upper section 26 of the reservoir and the lower section 27 terminates with the bracket- 28 by which it is secured to the side frames 29.

In the structure illustrated in Figures 6, 7 and 8, the reservoir is split vertically along its center line and the two sections 30 and 31 are secured to each other in any suitable manner, for example, by the provision of riveted flanges, as indicated at 32. Each section includes suitable brackets 33 for at tachment to the frame 34 and also includes one or more transverse braces 35 for connection to pedestal jaws 36 of the frame. Similarly, each section includes pipe brackets 37, expansion plate brackets 38, and brake hanger brackets 39.

In Figures 9, 10 and 11, the complete reservoir is embodied in a single structure 40 which is applied as a unit to the side frame 41 bv means of the brackets 42, certain of which bi'ackets also include the brake hanger brackets 43 and expansion plate brackets 44. The pipe brackets 45 are integral with the reservoir and the deep cross bar 46 is also integral with the reservoir and is attached to the'frame pedestals 47 as in the other struc tures previously described. If a reservoir of this type is formed by casting, as is my preferred construction, formation of the body will require a cylindrical core and, to facilitate the molding and casting operation, the shell of the reservoir will be provided with a series of openings 48 which are closed upon the completion of the device by welding suitable cover plates 49 to the body of the reservoir.

modification of my invention in which the lower portion 50 of the reservoir is formed integrally with the side frames 51 of the locomotive, suitable transverse members 52 corresponding generally to the brackets 3 and 4 of the preferred structure but merging with the sides of the locomotive frame. The brake hanger brackets 53 and the expansion plate brackets 54 are integral with the sides of the frame. Preferably, but not necessarily, the sides of the reservoir body 50 are connected at intervals by suitable braces 55.

The upper portion 56 of the reservoir is 61 provided on the main structure. Prefer-.

ably, each of the reservoir portions is suitably braced by braces 62 and 63, respectively, brace 62 being of deeper section to adequately brace the frame transversely of its length.

The modification illustrated in Figure 16 includes a main portion 64, the sides of which extend to a higher level than indicated in Figures 14 and 15 and the reservoir body is completed by the addition of a plain arcuate section 65 which may comprise a sheet of boiler plate, if desired. This element 65 overlaps the edge portions of member 64 and is secured thereto by screws 66 and by welding as indicated at W. By providing a suitable man hole in the reservoir, rivets may be substituted for screws 66. In all the forms of my invention, the general objects stated at the beginning of the specification are attained to a substantial degree. The material usually required for separately fabricating and mounting the ordinary reservoir tanks may be used to form a part of and strengthen the locomotive underframe and the space taken up on the exterior of the locomotive boiler by the usual reservoir may be used for other purposes. The center of gravity of the locomotive structure is lowered by carrying the air reservoirs between the sides of the framing instead of at a substantial height above the same.

In connection with the present application, I refer to my copending application Serial No. 407,199, filed of even date, some features of which are common to the present application.
