My invention relates to certain improvements in locomotive boiler supports, and this application is a companion application to that filed by Henry K. Harwich on November 9, 1929, under Serial No. 405,9911.

The obj ect of the present invention is to re inforce the frame of the locomotive by a boiler support which extends above the frame and is an integral part of the frame, and to provide saddles which are secured' to the scribed in detail hereinafter.

boiler and which are arranged to slide upon the boiler support.

The invention also relates to certain details of construction of the saddles as de- In the accompanying drawings: Fig. 1 is a side view of sufficient to a frame of a locomotive showing the boiler support and the saddles detached from the boiler,

the outline of the boiler being shown in dotted lines;

Fig. 2 is a plan view;

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

Fig. i is an enlarged sectional view on the` line 1r-4, Fig. 1; and

Fig. 5 is a detailed view showing one of the pads on the flange of a longitudinal web. Referring to the drawings, 1 1 are the side 3f frames of a locomotive, having the usual pedestals 2 which are cast integral with the side frames. Transverse members 3 tie the two side frames together at intervals. The entire structure is made as an integral cast- I ing but it will be understood, however, that stance, consists of two longitudinal webs 9` and transverse members a. These transverse members are arranged at intervals through- A5 out the length of the frame and have laterally eXtending webs 4a extending from the longitudinal webs 9 to points on the main frame, so as to reinforce the web 9 and to ina-y terially increase the strength ofthe entire structure. By extending the boiler support Y construction of the entire frame. At the upp pad which is located betweenthe -iianges 6 ofv a considerable distance above the main frame, the vertical depth of theframe is iincreased andv strengthened and the depth 'over the pedestalsis increased, Jermitting .a'lighter per, edge'of each longitudinal web 9 is a flange Y l 10 and at intervalsthis flange Vis'enlarged to form raised pads 11 V(Figs. and-5). The flanges 10 materially strengthen the longitudinal webs and connect the several pads which carry the boiler. l 'yA l rlhese segmental flanges 6 of the saddles are secured tothe boiler a by rivets or studs, or'- theymay be welded thereto if desired. 7 is a` Figi-3.

Each saddle is made as lshown in Figs. 3 and. fi and has' ay portion 12which is directly above the upper surface'of the pad 11, and between this padv 11 and the portion 12 ofthe saddle 5 is a gib 13, which provides Ia renewable wearing surface and also facilitates fin-v ishing in-this shop as this gibis applied after the saddle is attached to the boiler.Y These gibs ,have lips'at Vboth ends-toretain theniin place and are held transversely of the -locomotive by tap bolts le in the present? instance. Eachsaddle has' a dependingpon tion 15y which is opposite the edge ofthe pad 11, and betweenthis extension and the. edge "of the pad is av gib M16, having lips at each end "for retaining it in position on the saddle and this gib provides' a renewable y wearing`- surface. y y .I

- A cap vplate 17 issecured bypa stud bolt 18 the saddles 5 and the boiler as shown 'in to the underside of the extensionl of the.

'1n the present instance, I have shown 3 saddles "on each side of the `boiler support of the locomotive and these saddles are secured to ythe boiler in the manner shown and are `free to move longitudinally with the boiler on the boiler. support, to allow for expansion and contraction. This boiler support, as

. 00 stated above, 1s, 1n the present instance, an

integral part of the main frame of the locomotive.

1. The combination in a locomotive, of a main frame; a boiler support thereon projecting above the forward frame and oonsisting of two longitudinal webs spaced apart; pads on the webs; and saddles on the boiler arranged to slide on the pads of the boiler support. A l

2. The combinationy in a locomotive, of a4 main frame; a boiler supportextending. above the main frame having Va longitudinal flange; pads arranged atintervals o-n the l5 flange; and saddles arranged to be secured tova boiler and to slide on the pads.

3. The combination in a. locomotive, of a main frame integral boiler supports extending above the mainframe, the support consisting of longitudinal webs and transverse members connecting the iwebs, Leach longitudinal web having a flange at its upper end;

and a series-of saddles arranged to be secured tothev boiler, said saddles being located directly above the flanges of the webs and having cap plates extending underthe webs.

4. The combination in v.a locomotive, of a main frame; integral boiler supports eXtendy ing above the main frame, each support connfsisting'of longitudinal webs and transverse 'members connecting the `webs,each longitudinal web having a flange at its upper end; arseries of saddles arranged to be sef'cured tothe boiler, said saddles being located directly above the flanges of the Webs and having cap plates extending under the webs; gibs carried by each saddle and located between the upper surface of the flange of the cap and the saddle; and a second gibbearing 40: against the edgeof the flange.

5. The combination in a locomotive, of a main frame; a boiler support forming an integral part of said main frame Vand con- `sisting of two longitudinal webs spaced apart 5"" and connected together by transverse members, each longitudinal web having a vseries Y of pads at its upper edge; a series of saddles secured to the boiler and located above the lpads of the boiler support, said saddles hav- "ing depending portions projecting at the edges of' the pads; a. gib mounted between the' saddle Vand the upper surface of a pad; a second gib mounted between the depending portion of the saddle and the edge of the padg anda cap plate secured to the saddle and extending under the pad, said pads being arranged so that the saddles can slide freely on the pads. 6, y EDWARD O.
