'Y., ASSIGNOR TO THE STANDARD STOKER COMPANY, INCORPORATED, A CORPORATION OF DELAWARE LOCOMOTIVE CAB UNDERFRAME Application filed November 29, 1930. semrno. 498,987.

This invention relates generally to locomotive construction and more particularly to improvements in the construction of locomotive cab underframes. 35' An object of the invention is the provision of a new and improved locomotive cab underframe construction wherebythe design is materially simplified, the number of separable parts is reduced, cost of construction in and maintenance is lowered and a more durable and lighter construction is produced.

It is a further object of the invention to provide in a stoker equipped locomotive. a construction wherein the stoker fuel deliv- 15 eryconduit is formed as an integral unit with the locomotive cab underframe, or as a detachable unit if preferred.

It is a further object of the invention to provide in a striker equipped locomotive, a 2% construction wherein the locomotive cab underframe is formed with an upstanding flange, the upper portion of which is aper-v tured to form a firedoor ring and the lower portion thereof is apcrtured to receive a 2 stoker fuel conduit.

It is a further object of the invention to provide in a locomotive, a novel cab underframe having formed therewith means for supporting a locomotive cab.

36 To the above and other ends my invention" consists in a certain novel features of construction, and arrangement of parts hereinafter more fully described andillustrated in the accompanying drawings, in which Fig. 1 is a central longitudinal section through the rearward portion of a locomotive showing the invention in similar section;

Fig. 2 is a sectional view on the line 22 of Fig. 1;

Fig. 3 is a sectional view on the line 3-3 of Fig. 1;

Fig. 4 IS an isometric view of the novel cab underfrarne Fig. 5 is a fragmentary view similar to Fig. 1 showing a modified form of the invention; and o Fig. 6 is a plan view on the line 66 of Fig. 5. v In the drawings the locomotive is indicated generally by the numeral 10 and includes the main frame 11, the cab 12 and cab deck 13. At 14, there is shown the backhead of the firebox 15, constituting a water le of the boiler 16. A portion of the grate o the firebox is shownat- 17. The backhead 14. has an opening 18 therethrough arranged to form both a hand firing opening and a stoker firing opening. The cab 12 is supported by the cab underframe 19 which will be hereinafter described more in detail.

' Referring more particularly to Figs. 1 to 4 inclusive, the cab underframe 19 is shown as comprising the horizontal plate member or floor 20 which is cored or apertured as at 21 in order to reduce the weight thereof, and recessed at 22 to conform with the shape of the rearward portion of the boiler 16. Formed with the forward edge of the plate member 20 and located centrally thereof is an upstandingflange 23 extending above and below the horizontal plane of the plate member 20 and attached by suitable means to the backhead 14 at the marginal edges of the opening 18. The cab underframe 19 is provided with the integrally formed

upstanding flanges

24 and 25, to which are attached the

cab side sheets

26 and 27 respectively; the

upstanding flanges

28 and 29 to which is attached-the cab rear sheet 30; and the

upstanding flanges

31 and 32 to which is attached the cab front sheet 33. The cab underframe isprovided with an integrally formed depending flange 3 1 at its rearward end and an integrally formed flange 34a.

depending from the cab underframe plate member 20 adjacent the backhead 14 and arranged for attachment thereto, whereby the cab under frame is securely attached to the boiler backhead. Additional depending integrallyformed flanges 35 and 36 may be provided for further securing the cab underframe from the boiler16.

The boiler 16 is supported at its rearward end fromthe main frame 11 by the yieldable plate 87, which is attached at its upper end to the boiler mud ring 38. A flexible plate 39 attached at its upper end to the flange 34 supports the cab under frame 19 at its rearward end from the main frame 11. It will thus be seen that the cab underframe is free to move with the backhead as it expands and contracts by reason of its being flexibly supported from the main frame 11,.

A stoker conduit 40 is formed, preferably although not necessarily, with the cab underframe 19 and its mouth portion 41 may be formed integral with the lower portion of the flange 23. The upper portion of the flange 23 is apertured at 42 to form a firedoor ring 43 and the lower portion thereofis arranged to form a closure for the lower portion of the opening 18 in the backhead 14. 7 he mouth portion 41 of the stoker conduit extends through the plane of the flange 23, into the firebox 15 and opens upwardly therein to deliver fuel at a height above the normal level of the fire. An opening 44 in the cab underframe 19 communicates with the stoker conduit 40, and a corresponding opening in the cab deck 13 permits easy access to the stoker conduit 40 for purposes of inspection and permits the fireman to observe the rate of delivery of the fuel. Agrating 45 constituting a portion of the cab deck forms an apertured cover for the opening to the stoker conduit 40.

Fuel is advanced throu h the stoker conduit 40 to the firebox by the screw conve or 46. Suitable means is provided for delivering fuel from a source of supply, as a locomotive tender, not shown, to the stoker conduit 40 including a telescoping conduit 47, the forward portion of which is universally connect ed to the rearward end of the stoker conduit 40 and a screw conveyor 48 mounted in the telescoping conduit- 47 and universally con nected to the screw conveyor 46.

The fuel distributing mechanism comprises a plate 49 which extends laterally from the upper margin of the stoker mouth portion 41 and is preferably level, serving as a table over which the fuel issuing from the mouth portion 41 may be swept by steam jets 50 issuing from the nozzle 51 located in the recess at the upper rearward side of the mouth portion 41.

In Figs. 5 and 6 is illustrated a modified form of the invention in which the cab underframe floor forms the cab deck proper, and in which the mouth ortion of the stoker conduit is made remova le. As in the preferred modification a rearward section 52 of the stoker conduit 53 may be formed integral with the cab underframe 19 and the flange 23, but the mouth portion 53, which is in effect a continuation of the rearward conduit section 52, can be detached if found destroyed by the heat of the fire or worn by the passage of fuel therethrough. The mouth portion 54 has formed therewith a laterally extending flange 55 which when applied is received in the seat 56 formed by the U-shaped lug 57 formed vertically on the flan e 23 adjacent the opening formed by the sto er conduti 53 through the plane of the flange 23.

It is believed evident from the drawings and the description that my invention provides a id durable structure which is simple in esign and forms a stronger construction than the sameweight of metal ina fabricated structure and b reason of the-imcreased strength permits t e use of a lighter structure than is possible with. a fabricated structure. There are no joints to work loose and there is no maintenance after the structure is once assembled into a locomotive. Furthermore, it permits a more direct delivery of the fuel through a forward conduit section free fromabrupt angles or obstructive curves such as may pulverize lump fuel in its conveyance to the firebox.
