Application filed December 16, 1926. Serial No. 155,323.

My invention relates to new and useful improvements in locomotives and more particularly to the foundation ring or mud ring which is a metallic member shaped to corre- 'spond to the ground plan of the locomotive fire box. It separates the inside and outside sheets of the fire box and forms the foundation to which these sheets are attached.

"The present device is directed particularly W to types similar to those locomotives in which the trailer trucks are arranged to take care of the pulling and bufing stresses. It has heretofore been customary to form the deck plate in a separate piece and bolt it to the rearward end of the mud ring.

My invention contemplates and its principal object is to form theideck plate and mud ring integrally.

Another object is to provide integral means for the attachment of the cab sheets.

A further-object is to provide integralstoker supporting pads which may he located to accommodate" difi'erent types of sto'kers by slight change in the core box arrangement at the time of casting.

A still further object is to provide the under-surface of a unitary mud ring and deck plate with integrally formed pads or brackets toward the rear end on the sides I to rest on the roller or rocker nnunbers of the trailing truck.

With the foregoing and other objects in View in invention consists in" certain featureso construction and arrangement of parts hereinafter more fully described and illustrated in the accompanying drawings, in which Figure 1 is atop plan'view of my integrally formed mud ring and deck plate.

Figure 2 is a side elevation showing the arrangement oftheparts in relation to a locomotive.

Figure 3 isa plan view of a modified form providing for a difierent type of stoker and having a mud ring of different cross section. v

Figure. 4 is a side elevation of the modified form shown in Figure 3.

Figures 5 to 10 are cross sectional views showing various forms and modifications of mud rings and the method of attaching the inner and outer fire box sheets thereto.

The numeral 1 in the drawings indicates the, main frame of a locomotive, 2 is the trailing truck connected at its forward end to the main frame 1 and provided at its rear end with draft rigging 3. This ar rangement of the parts provides for the transmission of all pulling and bufiing stresses through the trailing truck rather than through the rearward portion of the locomotive above the trailing truck. Boiler or rocker bearings i are mounted on the' top surface of the trailing truck to support the rear end of the locomotive. I

Mud ring 5 which is located over the upper edges of the ash pan 6 is provided on its forward end with dependin feet 7. These feet 7 are preferably forme integrally with the mud ring and are adapted to slide-iongitudinally in a groove in the main name-1 but held against lateral displacement. Along the lower rear edge of mud ring 5 and pro ecting rearwardiy therefrom, the

deck plate 8 is formed as an integral por- 7 deck plate 8, a bracket 10 is provided for the support of the cab sheet, not shown.

Integrally formed brackets 11 adapted to bear on rockensu'p orts 4: are located underneath and atthe side adjacent 'thepoint of merging between deck. plate and mud ring portions of the frame. Suitable webbing 12 is provided to support the portion of'these brackets which extend beyond the main body of the deck plate 8. As shown in the preferred form which is illustrated in Figures 1 and 2, provision is made for an automatic Stoker, not shown, by providing brackets 13 onthe forward port on of the upper surface of the longitiidinal as tree 9. However, all types of stokers cannot'be accommodated b support in this 10- pation, so in the modi ed form illustrated n Figures 3 and 4, integrally depending lugs 14.- are provided on the forward member of-the deck plate 8. Lugs 14 are provided with brackets 15 which suitably fit types of stokers other than those accommodated by the brackets 13 shown in Figures 1 and 2. Bracket 16 depends from the rear member of deck plate 8 to form a supporting mempr for the rear cab sheet in this construc- The lower edges of the inner and outer lire box sheets terminate at the mud ring 5. These sheets are suitably fastened to the mud ring preferably by rivets. Figures 5 to 10 inclusive illustrate cross sectional views of various styles of mud rings and the method of fastening the tire box sheets to this member. The mud ring 5 in Figure 5 is solid and substantially rectangular in cross section. The inner fire box sheet 17 and the outer fire box sheet 18 are fastened by a single rivet passing through both sheets and the mud ring.

In the form shown in Figure 6 the mud ring 19 is of inverted [Ll-shaped cross section and separate rivets are used for fastening the inner and outer fire box sheets 17 and 18, respectively.

The modification shown in Figure 7 is similar to that of Figure 6 except that the sides oi the mud ring 20 are inclined to the vertical and inwardly extending beads 21 are provided along the lower edges. In this form the fire box sheets have their? lower edges slightly bent to conform to the mud ring and separate rivets are used for each sheet.

In Figure 8 a hollow mud ring 22 is shown. Shoulders 23 incline to the vertical are provided for contact with the tire box sheets. Openings 24 in the lower surface permit access to the interior for the purpose of riveting the fire box sheets in place. Inwardly. extending beads 25 surround the openings 24:.

Figure Sillustrates a mud ring 26 similar to the one shown in Figure 8, the difierence being that the ring is shallower and the beads surrounding the openings are omitted. In this mud ring the sides throughout their length are inclined to the vertical instead of havin vertical sides with an inclined shoul er as shown in Figure 8.

The tubularmud ring 27 shown in Figures 3, 4t andlO is for use with a water tube boiler. With this type of boiler a single fire box sheet is carried by lugs 28. "Water tubes 29 connect with the mud ring 27 so that the water circulates through the mud ring as well vas through the tubing. Lugs 30 are provided on the inner side of mud ring 27 to carry the grate bars, not shown. The upper ash pan portion 31 is formed integrally with mud ring 27 and joined thereto by members 32. The ash pan 33 is carried by the upper ash. pan portion.

It can be readily understood that the unitary construction of the mud ring and deck plate and their component parts as set forth herein forms a stronger construction than the same wei ht of metal in a fabricated structure an a lighter structure for the necessary strength than is possible with the fabricated construction. There are no joints to work loose and there is no mainnevaeeo tenance after the member is once assembled into a locomotive.

lit is to be understood that minor changes in the size, form and construction of the various parts of my device may be made and substituted for those herein shown and described without departing from the spirit of my invention as expressed'in the following claims.

I claim:

1. As a new article of manufacture, a locomotive mud ring having a deck plate formed therewith.

2. As a new article of manufacture, a locomotive mud ring having a deck plate termed therewith, and means formed with. said deck pl ate for the attachment of a stoker.

In testimony whereof I hereunto afiix my signature this7th day of December, 1926.

WILLIAM M SHEEHAN.
