20 Claims. (01. 105-234) This invention relates to railway rolling stock and consists in'novel locomotive tender framing arranged for various locomotive auxiliary equipment units, such as the stoker engine, turbo -generator, air and water pumps and air reservoir,

At present it iscustomary to mount the equipment mentioned on the boiler or on the engine bed either at the front or at the side of or below the boiler; The air and water pumps particm ularly are compartively large and heavy units and because of their proximity to other equipment are mounted with some difiiculty. Thestoker engine is usually located adjacent to the cab'deck which location necessitates the extension of the driv- 5 ing connection to the stoker feed screw across thespace between the engine and tender and otherwise complicates the coupling of the engine and tender because it restricts the space for the draw bars, piping, and other equipment, and re- 20 quires a telescopingjoint in the driving connection; =The engine parts are not/readily accessible for inspection and repairs. V

g In order to avoid some of the above-mentioned difiiculties, the mounting of the air and water 25 pumps on-the engine front deck has been sug ested. However, this necessitatesthe lengthening of the engine and complicates the proper distribution of weight on the drivers. Obviously, the stcker engine, located beneath the 'calousimiiarly -30 affects the weight distribution. 7

* MoreoveL-the weight of the large locomotives now being built approaches the maximum permissible rail loads and makes desirable the removal of heavy equipment to the tender.

'35 -One object oithe present invention is to provide a 'donmressed air reservoir in the tender framing; x '1 wrAnother object. of "the present irivention is to provide tenderstructure ior'carry-ing the air and & water pumps,,.stoker engine-andturbmgenerator and, aecoi dingly, decreasing the weight ofgthe engine. .Zfi

Another pbiect is to facilitate the mounting and dismountmg-of the aboveeznentio-ned equipment and-placeathez same a:position toibe more readatccssible'zfor the purpose of inspection and re- Pairs.

Another object is to simplify the connection betweentthe :stoker engine and stoker feed screw;

50 Another object is to provide'a suitable passage tor piping between the locomotive and the equipinentat 'the'near of the tender. t V

iThese'and other objects are attained in the structure illustrated in the accompanying draw- 55 dines nfwhifih I 5 a a T Figure 1 is a top view of the rear end of a tender embodying my invention but with the top plate of the water compartment removed and the vertical plates sectioned.

The tender rear end structure illustrated in Figures 1 to 10 is applied to an integral waterbottom tender underframe casting of the general type disclosed in Patent No. 1,663,036, issued to .30 Pflager & Ashe. The underirame includes side sills I, rear end sill 2 having the usual draft sills 3 depending therefrom, box-shaped center sill l0, and bottom web 4 which constitutes the tank bottom. A vertical web .9, extending across the underframe on a line spaced from the end sill 2, forms the rear wall for the water space within the underirame casting and also projects slightly above the top of the casting to provide a shoulder V y Mounted upon the portion of the underframe rearwardly of upright web .9 and abuttingshouh der S is an upright box-like skeleton structure comprising an outer frame including transverse horizontal members ll and I2 and vertical posts l5, l1 and I9, and an inner frame including horizontal members l3 I4, 23, 24, 25 and '26, and vertical posts is, I8, 20,21, 22, 21 and 28. These frame portions are connected by upper bars 29, sags- L miter bars 32, 33,34, 39, 40, 4 42, 1ntermediate side bars 35 and 36, and intermediate center bars 37 and 38. a

The various elements of the skeleton frame structure are shaped for maximum strengthand convenience .of attaching othermemloers thereto,

and preferably, but not necessarily, form an integral structure which may be applied to the tender underframe as a unit.

Preferably, the upper outer portion of the upright frame includes an air reservoir 80 extending from side to side of the tender, the wall of the reservoir merging with the flanges of the transverse member II.

The tender superstructure includes a top sheet 5, end sheet 6, and side sheets 'I, all of which may be secured to the tender framing by riveting or welding. A coal hopper having a bottom sheet 8 is provided in the forward portion of the superstructure. An end sheet 6 is spaced inwardly from the rear end sill 2, but the top and side sheets of the tank extend rearwardly substantially to the end of the underframe and form an enclosure for the equipment mounted in the box like upright frame.

Mounted on the right-hand side of the structure (Figures 1 and 2) are a water pump 43, secured to the horizontal and vertical members 25, 26, 21 and 28, and a turbo-generator 44 secured to pads 53 on the horizontal web 54 extending between longitudinal bottom members M and 42 and braced by the rib R. (Figure 7.)

On the left-hand side of the structure, air pump 45 is secured to vertical and horizontal members 2|, 22, 23 and 24, and stoker engine 46 is secured to pads 55 on longitudinal bottom members 39 and 40.

7 To provide for the various steam, air, and water connections extending between the engine and the equipment mounted on the rear end of the tender, the upper corners of the superstructure include longitudinal passages 41 and 48 formed 7 by suitable plates connected to the top and side sheets.

A cylindrical housing 56 extends from an opening 51 in the tank end sheet 6 through the water space of the tender superstructure to the coal hopper 8} Within this housing extends a driving'shaft 59 which has flexible couplings 66 and 6| with stoker engine 46 and feed screw 62 respectively, the feed screw being located in trough 5B in the bottom of the hopper.

Water is led from the tender to the water pump 43through pipe 63 and then passes through 1 pipe 64, which is enclosed in the passage 48, to

a feed water heater. Live steam for operating the air pump 45 and stoker engine 46 is led from the boiler through pipes 65 and 66 enclosed in passage 41 where they extend along the tender. Live steam for the water pump 43 and generator 44 reaches the respective units through pipes 98 and 61 in passage 48. Exhaust steam passes from the air. pump 45 throughpipe 69, from the stoker engine through pipe I6, from the generator through pipe II and from the water pump through pipe I2. Pipe i2 is larger in diameter than the other pipes and the other pipes lead into pipe I2 which conducts the total exhaust over the top of the tender superstructure to the tender water compartment. 7

,- Pipe .BI leadsfrom the air pump 45 upwardly and rearwardly to a coil 82 of radiating pipes from which the air passes through a connection 83 to the reservoir 89 from which air is supplied to the air brakes and other equipment utilizing compressed air.

rear end of the tender through a passage therefor formed in the underframe.

In this modification the rear upright members 85 and the forward upright members 86, the lower transverse members 81, the upper transverse members 88 and the intermediate transverse members 89 and the longitudinal members 96, connecting the front and rear portions of the frame, are substantially the same as in the structure illustrated in Figures 1 to 10.

The water pump 43, turbo-generator 44, the air pump 45 and the stoker engine 46 are mounted on the end frame as previously described, but the piping to and from this equipment is conducted through passages 9| formed in the underframe by the bottom web W and the side wall W' of the latter, and an integral wall 92 and top web 93 cast therewith to form a box-like chamber, the lower wall of which may have Openings II I to provide access to the piping. A section through these housings-is indicated in Figure 15.

The water supply pipe 94 comes through the right-hand passage 9I and leads to the water pump 43 and the water is discharged through pipe 95 which leads back to the locomotive through the left-hand passage 9|. Live steam for operating the air pump and stoker engine comes through pipes 96 and 91 respectively, located in left-hand passage 9|, and live steam for the water pump and generator comes through pipes 98 and 99 respectively, located in the right-hand passage 9 I. Pipe I94 leads from the air pump to the air reservoir.

Exhaust steam from the stoker engine leads through pipe IIII which discharges into pipe I66 leading from the air pump 45. Exhaust steam from the water pump leads through pipe I03 and receives the discharge from pipe I00 and also receives the discharge from the generator leading through pipe I02. Pipe I03 extends over the top ofthe tank to the locomotive similarly to the arrangement previously described.

The structure in Figures 11 and 12 utilize a lighter end frame member by eliminating the air tank, which arrangement may be preferred if it is satisfactory to mount the air tank on the locomotive. This structure also eliminates the provision of passageways in the upper portion of the tank body, which may be preferred in some installations.

It will be understood that the structure of both forms is adapted for or could easily be arranged to mount other equipment advantageously. The underframe need not be of the water-bottom type shown, but could be of any design which is provided with suitable elementsfor attachment of the rear end structure. -The rear end structure need not be integral as shown,as the invention could be embodied in a built-up structure. The various framing members may vary in number, shape and size, according to the requirements of the equipment to be accommodated.

These and other modifications may be made in the structure illustrated without departing from the spirit of the invention and I contemplate the exclusive use of all such modifications as come within the scope of my claims.
