This invention relates to locomotives, and more particularly to frames therefor, and to supportingstructures, valve chests, and cyln inders associated with the frames. K

5 An object of the present invention is to provideV a locomotive frame of greater strength in proportion to its weight, and which can be more economically manufac- A further object of the invention is to provide a structure wherein is combined a. locomotive frame, and a cylinder saddle and bumper beam bracket, which structure is more economical to manufacture andmaintain and possesses greaterv strength than those heretofore known. A

A further object of the invention is to provide a locomotive frame which while possessing adequate strength to meet all service requirements eiects a substantial saving in weight, thus enabling the economy in weight to be utilized in the boiler, or. in the case of heavy road locomotives, 'enabling the stolzer engine to be mounted o-n the locomotive, instead of on the tender to. save weight, as has been required with such locomotives using the heavy frames heretofore known.

A further object of the invention is to provide a cylinder saddle and cylinder castings so formed that when assembled they will present a iiat platform for the application lof theV iiat bottom of a smoke box, thus obviating the expensive machining operations required to provide such parts with a fit for a cylindrical smoke box.

'A further object oli the invention is to combine in an integral lcasting a 4cylinder saddle, a bumper beampbracket, guide yoke supports, a `cross-tie for the supports, brake cylinder supports, brake shaft fulcrums, and a truck center-pin. Y

YA further object of the invention is vto tured and maintained, than those heretofore curved and bumper beam casting.

combine with the novel frame and cylinder saddle construction, separately formed castings eachvembodying a cylinder and a distrib'ution'valve chest', thus eecting a'substantial economy in manufacturingcost, lessening the danger of shrink cracks, and probe readily disassembled for repairs.

A further object of the invention is to prot., videa novel construction of smoke box and cylinder castings wherein the steam supply passage to the distribution valve chest leads through the cylinder castings kdirectly into the smoke boX, withoutl passing outside of the casting and the smoke boX as in former practice.

Other objects of the invention will hereinafter readily appear.

The improvement claimed is hereinafter fully set forth.

Fw. 6, aview on an enlarged scale, half 'in front elevation and half in transverse vertical section on the line ,VI-VI of Fig. 8, showing the combined cylinder saddle and bumper bracket casting; Fig. 7, a view half in plan and halt in transverse section on the line VII-VIIo- Fig. 8; and, Fig. 8, a side elevation oi the combined cylinder saddle ln the practice of the invention, referring descriptively lto the `specilic embodiment thereof which has beenselected for exemplification herein, the frame comprises two side frame memberslO, of conventional design, each embodying top rails 10a, bottom rails 10b, and pedestals 100.

The side frame members are joined together at their tops by a tophorizontal plate 11, which may be of'rolled steel or other suitable material, and which is welded to the top rails 10a, by corner welds 110, and plug welds 11fl,formed by boring vertical holes through the sheet and into the top rails, lilling the holes with welding material, and fusing such material to the walls of the holes. It is within the contemplation of the invention to use instead of a single plate 11, a plurality of plates. y

The bottom rails 10b, of the side frame members are joined together by bottom horizontal plates 12, tothe top plates. Y The plates 12,l may be of rolled steel or other suitable material.

To provide for stiening the top and bot-l tom plates they are welded to transverse I-A beams 13', by welds simi-lar to those used for attaching the top plate to the side frame members. lIt is within the contemplation of the invention to use instead of I-beams, plates or pieces of any suitable-form. y

The frame structureis also additionally reinforced by4 inverted transverse T-pieces 14, welded to the top plate by welds similar to those used for attaching the top plate to the Yside frame members, the stem 14a, of the T-pieces may be used to anchor supporting sheets (not shown) for the waist of a boiler. It is within the contemplation of the invention to use instead of the T-pieces, plates or pieces ofV any suitable form.y

It is within the contemplation of the invention to use instead of welds for connecting the described parts, bolts, rivets, or any other Ysuitable means, or combinationv of means as desired. v

`,From the foregoing description, it will be obvious that the primary means for'tying the side frame members together comprises transverse, horizontal plates, suitably braced by transverse vertical plates.V Y

The described construction, enables the side frame members to be machined in pairs before assembly, and is characterized by its extremely light weight and great strength. The material saving in weight-effected can be utilized to increase the weight ofthe boiler, or in the case of heavy road locomotives enables the stoker engine to be placed onk the locomotiveV instead of on the tender as has been required in locomotives using the heavy frames of former practice.

The combined cylinder saddle and bumper beam bracket casting comprises in an integral casting a saddley 15, a bumper bracket 16, a truck center pin 17, guide yoke supports 18, a :cross tie 19, for the guide yoke supports, brake cylinder supports 20, and brake shaft `fulcrums 22. y

welded in position similarly through the saddle from each of the side-y walls 15a to the top wall 15d, are exhaust" steam passages 15e. The sidewalls 15a of the saddle are each extended beyond the end walls 15b to provide flanges lfhaving bolt holes 15g for the attachment of the side frame members 10,'a'ndcylinder castings, to the cylinder saddle casting. The top walli 15d of the saddle iseXtended beyond the end walls Vlbto provide flanges 15h having bolt holes 15a', for the attachment of the flat bottom plate 23, of a smoke box 24. l

The truck center pin 17, projects vertically downward fr oingthe horizontal bottom, wall, 15o, of the saddle. Y v l f v The vbumper beam bracket lvis connected to the front end wall15b of the saddle by a horizontal web 16a, and longitudinal vertical flanges 165, having bolt holes 160, for bolting to the side frame members 10.

Extending to the rear of the saddle is av box shape structure 25, comprising vertical sidek wallsl 25a, having .bolt holes 25?), for

vbolting to the side frame members 10, yand above and laterally beyond the side walls to provide the aforesaid guide yoke supports 18,a cross-tie 19, therefor, and a support 21, .to which a bracket of any well Vknown design may be secured for supporting the waist of a llocomotive boiler. Y

lxtendingy to the rear of the box shape structure are vertical flanges26, formed with the aforesaid brake shaft fulcrums, 22, and bolt holes 26a, for attachment to the side frame members 10. 'Extending rearwardly from the rear wall 257, of the boxlshape structure 25, is al horizontal flange 25g, to which the top plate 11, of theV frame is connected by a weld 25h. 1 Each cylinder casting 27 comprises a cylinder 28; a distribution valve chest 29 a flat top wall providing end, flanges 30, and a side flange 30a, thesaid flanges yhaving bolt holes 306, for attachment of the flat bottom sheet 23 of the smoke box, and the flanges 30 matching with the flanges 1571, of the saddle to provide a platform for supporting the flat bottomrsheet 23 of the 'smoke box; and a passageway 31 for supplyingsteam to the valve chest. .By referring toV Fig. 5 of the v box, .thus avoiding the use of steamsupply pipes leading outside of the smoke boX to the valve chests as in former practice.

The described invention possesses the following advantages:

It provides a frame structure of less weight in proportion to its strength than those heretofore known, enabling the saving in weight to be utilized in increasing the Weight of the boiler, or to permit the Stoker engine of heavy locomotives to be mounted on the locomotive instead of on the tender.

It provides a saddle construction adapted to withstand the heavy stresses incident to service.

It provides a flat top cylinder casting and saddle construction, more economical to manufacture and maintain than thecurved constructions heretofore known.

It provides for supplying steam to the valve chests through passages leading through the cylinder casting directly int-o the smoke box, thus obviating the outside steam supply pipes and their lagging required in former practice.

While one of the preferred forms of construction lias been shown, it is obvious that many variations in procedure, form, arrangement and construction of the parts can be made, and the invention is not therefore limc ited to the particular embodiment disclosed, but includessuch changes and modifications as come within the spirit and scope ofthe invention as set forth in the appendedclaims.
