` LOCOMOT IVE--REAREND SUPPORT.

Application llcd April 27. 1925. Serial No. 26,012.

This application relates to supports at the rear end of locomotives and is in part a continuation of my copending application, Serial No. 576,788, filed July 22, 1922, which has been issued as Patent No. 1,536,036, granted April 28, 1925.

In standard locomotive practice the main extends underneath and rearwardly of the firebox, but according to the present invention, the main frame terminates in the region of the forward end of the fire-box, and the rear of the fire boxis supported on l truck frame, articulated to the main frame and having capacity for radial motion relative to the fire box. This introduces conditions not present in the old construction with reference to the support of the cab, the Stoker mechanism, the grat-e shakers, and injectors which must be ina fixed relation to the boiler.

lt is one of the primary objects of my invention to provide a convenient support for such parts.

lIn accordance with my invention, there is also a lateral mot-ion furnace bearer device,

my invention to transmit load thru the support herein described to such bearer.

How the foregoing, together with such other objects as may hereinafter appear, or are incident to my invention, are realized, is illustrated in preferred form in the accom panying drawings, wherein- Fig. 1 is a somewhat diagrammatic side elevation of a rear portion of a locomotive equipped with my improvements;

Fig. 2 is an end elevation of the device of Fig. 1, partly in section, such, however, bein T on an enlarged scale;

Figs. 3 and 4 are respectively a plan view and'side elevation of the support of my invention; and

Fig. is a fragmentary side elevation illustrating' a modifie-ation of the, invention.

Referring now to Figs. l and 2, the'reference numeral 7 indicates the furnace, or firebox ol' the locomotive. the locomotive being carried on the main f'rame 8 and on the articulated truck frame 9, before mentioned, such latter frame having one or more axles with wheels.

To the rear of the fire-box 7, is the cab 10 of the locomotive. The other parts, hereinbefore referred to, are indicated as follows:

The injectors by the reference numeral 11; the grate shaking cylinders by the reference numeral l2; and the stoker by the reference numeral 13. The lateral motion resisting furnace bearer, hercinbeforc referred to, is indicated by the reference numeral M The injectors 11, the grate shaker cylinders 12 and the cab with its deck, are supported by the combined support generally indicated by the reference character A. This support, in the main, comprises two side members, preferably castings, which side members are secured to the mud-ring 15 of the fire-box and extend rearwardly thereof. Each side member has a vertical flange lo', by means of which it` may be bolted to the lug 17, depending from the mud-ring 15. This flange upstands from the base-plate 18 and unites at the plate or flange 19, rising up from the base plate 18. Each Side member is secured to the mud-ring by the flange 19 in addition to flange 16. The flange 1G is also braced by the'ribs 2O and by the cross member 21, to be referred to hereinafter. Rising from the base plate 18 is another flange or plate 22 having a lip 23, sloping downwardly and forwardly. The cross member 21 has two ears 24 which are inclined in the same manner as the lip 23. The lip 23 and the lugs 24 carry-the ash pan deflectors indicated at 25, such deflectors serving to direct ashes into the ash pan 26, the ash pan proper being carried on the articulated frame These deflector parts are shown and described in my copending application, Serial No. 10,499 filed February 20, 1925.

The flange 16 is drilled at 27 for the attachment of the deflector plates 28EL which eo-operate with the ash pan proper.

Extending rearwardly from the cross member 19 and from the base plate 18 is an I-beam like portion 28, having an end flange 29 for the attachment of the cab plate 30, which in turn supports the cab deck 31 and eab 10. The flange 29 of cach side support also carries one of the cylinders 12. The injectors 11 are supported from the plate 30.

Thus it will be seen that in so far as the construction of Figs. 1 to 4 inclusive is concerned, the side members when bolted to the ring and with the plate 30 secured to the flanges 29 thereof, constitute a combined support for the cab and cab deck, the grate shaker cylinders and the injectors, as well as the support for those portions of the ash pan immediately beneath the fire-box and over-lying the ash pan proper 26.

rear with an upstanding The weight at the rear end of the fire-box is transmitted to the articulated frame thru the lateral motion bearer device 14, hereinbefore referred to, which device is interposed between the base plates 18 and the articulated frame 9, for which purpose the base plates 18 are machined.

Referring now to Fig. 5, the general arrangement is substantially as described. However, the side members A are of somewhat ditferent conguration and also carry or support the Stoker mechanism 13.

It will be seen that the attachment of the side members to the muda-ing is 'such as to afford great stability and strength.

I claim:

1. In combination in a locomotive, a firebox having a mud-ring, a cab, ash pan means, and a combined cab and ash pan means support secured to the mud-ring.

2. In combination in a locomotive, a firebox havinfir a mud-ring, a cab, ash pan means, and a conivbined c ab and ash pan means support secured to the mud ring together with a Stoker also carried by said support.

3. In a locomotive having a. boiler, fire# box and cab, the combination of a cab support secured to the mud-ring of the box, and an ash pan means for the box supported from the cab support, said support compris-A .vices adapted lo be secured to the mud-ring of the tire-box.

6. ln a locomotive havin an articulated truck under the lire-box, an customary rear end devices, a combined support for the devices adapted to be secured to the mud-ring of the fire-box, said support also serving as a'bearing means for the furnace bearer device.

7. In a locomotive having an articulated truck under the fire-box, and customary rear end auxiliaries, a combined support for the auxiliaries adapted to be secured to the mudring` ot' the fire-box, the support having lateral and longitudinal bolting flanges for attachment to the mud-ring corner portions.

In testimony whereof, I have hereunto signed my name.

WILLIAM `E. WOODARD.
