The general object of my invention, like that of the above mentioned application, is to produce a locomotive air reservoir located between the side frames of'the locomotive and formed of sufiicient cross sectional area to serve as a reinforcement of the framesand also forming a longitudinal member of the framing adapted to transmit longitudinal forces.

A more specific object of my invention is to simplify the casting operation of a reservoir member which is cast integral with the underframe. I also desire, in the preferred form of my invention, to form a section of a reservoir reinforcement member which in art, is integral with the locomotive be or rame and to complete the member with a separately formed section applied thereto. In the preferred form ofmy invention the side frames of the locomotive are united by a cylindrical reservoir member which either by itself, or in combination with co-operating members applied thereto, forms the backbone of the frame and serves to transmit the major portion of the vertical and lon 'tudinal forces present in the frame.

. 'fiese and other detailed objects of my invention are attained by the structure illustrated in the accompanying drawings in whichn 'Figure 1 is a top view of-one-half of a locomotive frame embodying my invention. Figure 2 is a side elevation of the same.

In the construction illustrated in Figures 1 to 5, inclusive, the side frames are indicated at 1 and are shown as includin pedestaljaws 2 and provided at intervals wit equalizer crums 3 and brake hanger brackets 4. 'The frames are united at their rear by a transverse member 6 which alsoforms the front end of a cradle having sides 7. 'While I show this cradle structure as formed integrally with frames 1, it will be understood that it may be separately formed and attached to the frames.

forward ends of the frames merge to form the front deck 8 and this portion of the structure is provided with integral pads 9 for mounting the brake cylinder 10.

Intermediate the side frames 1 and extending throughout a substantial portion of the length of the structure is a cylindrical member 11 having open ends and connected to the side frames by vertically spaced substantially horizontal webs 12 which are provided with substantial openings 13, whereby the structure is lightened Preferably, member 11, webs 12 and side frames 1 are all formed integrally with each other, either by casting in a single unit or by the welding together into an autogenous whole arts which have been formed separately. 'Ihe structure is reinforced by upstanding ribs 14 and by shorter upstanding elements 15 which also form brackets for mounting piping for conducting air, water and other fluids from one part of the locomotive to another. Below member 11 and merging therewith and with the pedestal jaws 2 are cross members or transoms 16. Suitable integral brackets 5 are provided at intervals for mounting the expansion plates 17 on which the boiler shell 18 is carried.

Member 11 terminates at its ends in vertical flanges 19 and the end portions of the reservoir are formed by cup-shaped members 20 and 21, respectively, each having flanges 22 on its inner end adapted to be bolted to the corresponding flanges 19 of the central member 11 of the reservoir. Horizontal flanges 23 are provided on the outer ends of members 20 and 21 and rest on the transverse members 6 and 8 of the frame.

In order that the members 20 and 21 may serve as reinforcements of the frame structure, I provide complementary lugs 25 and 26 on the frame and flange respectively and utilize wedges 27 to provide a thrust-resisting engagement between the lugs on the two parts. With this construction variations in the length and machining of members 11, 20 and 21 may be accommodated and draft and buffing forces may be absorbed or transmitted by the reservoir structure, the same forming a backbone of cylindrical section throughout that portion of the locomotive frame in which the effective depth of the side frames is greatly reduced because of the recesses for the driver axle boxes.

The side frames 1 are braced by suitable transoms or cross bars 28 extending below reservoir members 20 and 21 and having their upper elements depressed, as best shown in Figure 5, to clear the reservoir. End members 20 and 21 are provided with pipingbrackets 29 corresponding to brackets 15 on the central member 11.

In Figure 6 I indicate a modified form of wedging the reservoir end member 30 to the frame member 31. In this construction, a single wedge or key 32 is provided between 111 s 33 and 34.

igures 7, 8 and 9' illustrate a modification in which a cylindrical reservoir body member 35 is provided with integral brackets 36' for attachment to locomotive side frame members 37, and reservoir end members 38 are provided with similar brackets 39 for attachment to the side frames. Members 35 and 38 have abutting flanges 40 for attachment to each other and each of these members is preferably provided with brackets 41 for mounting piping. Members 38 also have expansion plate brackets 42 and member 35 has depending elements forming a transom 43 having a flange 44 for connection to the pedestal jaw 37*. With the above described structure, smaller units may be used and secured together by bolts, rivets or welding and, at the same time, the bracing of the side frame by cylindrical reinforcing member is effected.

Figures 10 and 11 illustrate another modification of the structure shown in Figures 1 to 5 in that the end members 45 applied to the open-ended cylindrical body 46 are relatively short and, in effect, comprise caps for the central member and have no connection with the side frames 47, apart. from their connection to the body member 46. With this construction, a relatively short reservoir is provided but the hollow cylindrical reinforcement of the spaced side frames is retained.

If desired, the frames may be connected to each other in any usual manner at points spaced from the reservoir longitudinally of the frame. Figures 12 to 15 illustrate a construction 1n which the reservoir main body member 48 comprises a cylinder with flanged ends 49 to which caps 50 are applied. Caps 50 include lateral extensions 51 secured to the side frames 52, preferably including expansion plate brackets .54 and brake hanger lugs 55 and piping brackets 56.

A transom 53 may be located intermediate the ends of the reservoir for the purpose of bracing the side frames but member 53 has no connection with the reservoir member 48 and does not extend over the top of the same.

Figure 16 illustrates a modified form of connection between the main reservoir member 57 and the end members 58. The latter is provided with a rib 59 spaced from its inner surface 60 and providing a shouldered recess adapted to receive the edge and adjacent portion of the cylindrical body member 57. Member 58 is welded to 57 at W.

In the construction illustrated in Figure 13, the reservoir is so located relative to the pedestals that the end members 50 are intermediate the drivers and there is no occasion for providing members 51 with the downward extensions for connection to the pedestal jaws such as are provided on member 53 but it will be understood that if the length of the reservoir is such as to bring the end members abreast of pedestal jaws, it would 13 In the construction shown in Figure 18,

the transverse bars 63 are formed integrally with the side frames 64 and extend around the reservoir 65 which is made separately and placed in the mold before pouring the frame.

Figure 19 illustrates a structure similar to that shown in Figure 17 but in which the upper (portion 66 of the transverse bars 67 is in g m orcement for the same and also forming forme separately'from the lower and main portion and is bolted or riveted thereto as indicated at 68.

Figure 20 illustrates a similar modification of the structure shown in Figure 18, the lower main portion 68 of the transverse bars being formed integrally with the side frame 69, the upper portion 70 being formed separately and secured to the lower portion and frame by bolts or rivets at 71.

In each of the forms of my invention described above, the side frames are braced by a tubular member which also forms an air reservoir located between the frames. This construction avoids the location of reservoirs on the exterior of the boiler shell and eliminates the material and labor required for securing the reservoirs in their usual location. The center of gravity of the locomotive is lowered and less material is required for the side frames in order to attain a given resistance to forces transmitted through the underframe.

Various other modifications in the details and arrangement of the reservoir parts may be made without departing from the spirit of my invention and I contemplate the exclusive use of such variations as come within the scope of my claims.
