ROBERT B. KRUEGER, or LIMA, onro LOCOMOTIVE FRAME AND ENGINE SUPPORTING STRUCTURE Application filed June 22,

' "Stilloth'er objects are: to provide for a firm tyingtogether of all the parts involved while atthe same time making provision for r'eadynaccess toithem for the purpose of 1nspecting, taking-down, and assembling; to

"- provide means for mounting the engine structure which serves to reinforce the frame; and to provide cylinder-supporting means which will not interfere with the installation of steam pipes and other elements in the most convenient manner.

"How these objects and advantages are attained, together with others which are incldent to the invention or which will occur to those-skilled in the art, will appear clearly Y from thefollowing description, reference being had to the accompanying drawings, in which:

Fig-u're'l is a: transverse section through a geared locomotive, looking forwardly, with certain parts brokena'way and others omitof the lo'comotive), and lower and upper 1928n Serial No. 287,459.

cross-members:5,6, the frame, in turn, carrying a boiler? and cab 8; and it will be seen that, the frameand boiler-are ofiset from the longitudinal center line of the wheelbase, in order to provide the necessary space at the right for the mounting of the driving mechanism.

The vertical web of the frame member 4, as clearly shown in F ig; 3, has a large openingaor cut-out portion, indicated in general bythereference character "A, to facilitate access to adjacent parts, and to the staybolts of the firebox-9, and theframe member 3 may, of-course, be similarlyepertured (in that portion lying adjacent the side ofthe fire-box 9 to ,give ready access .to the staybolts. Frame members is built up at topcrand bottom with .flai-i-geseta and 4b. i

7 Along the bottom of theframe member 4; is-secured a.:boXlikestructurelO with diagonal bracing webs 10a, saidstructure having a series of innerand outer legsll, 12, forming longitudinally ofthe engineaseriesof gaps 1'3 inwh-ich the usual cranks and connecting rods (not shown) operate (see Fig. 3.) and formingbetween each pair. of legs .11, 12, a recess 14 (see Fig. 2) to receive a crankshaft bearing, This 1 wholestructure, with its flat longitudinal .-upper face 15,-eXt-ends substan tially the full length of the gap A in the side frame 14, and, is secured "by its integral angular web 16,:1-10111 the bottom of said frame 4, as bolts 17 av reinforcement to the main frame along the bottom of the opening. o Along the top of the frame member 4 I secure a. bridge-like. angle member 18 having s'tiifening. webs1 9, extending beyond the ends of the gap or opening A, and to this and the frame member ad I secure, as by

bolts

20, 21, the angular brackets 22 of the supporting structure '23, 24, 25, 26. This supporting structure, of which there is one for each cylinder,- consists of a 'base plate 23, a pair of upright crosshea'd guides 24, aydiagonal brace 25 and a head or top plate'26,-thebase being securedfirnrly, as by'bolts 2'? to the top 15 of the structure 10,- and the top plate26' formin- -a base for acylinder'28 which is'secured mg thereto, as bybolts*29. The diagonalbraces V gaid web thereby serves as 25, together with the webs 10a of the structure 10, form a trussed connection between the upper and lower p arts of frame member 4.

The cylinders each carry, laterally, a valvechest 30, and on the back, or the side toward the boiler, each is preferably provided with means, such as the tapped boss 31, whereby it may be secured to the boiler 7 by means of a bracket or brace 3s and bolts 3-3, 34. Main steam and exhaust pipes 35 and 36, respectively, may be positioned above and below the brackets 32 of the several cylinders, lying longitudinally of the locomotive between the cylinders and

chests

28 and 30, on the one hand, and the boiler 7, on the other hand. From these pipes, branches 3?, 88, may connect to the inlets and outlets of the valve-chests. All th se piping arrangements may be conveniently made, without interference from the z-aupporting structure shown.

It will now be evident that the engine construction, including the cylinders with their valve-chests, the cross-head guides, and the crank-shaft bearing brackets, are rigidly and securely mounted both at top and bottom of the girder frame member s; that the

angle structures

16 and 22, thewebbed angle bar or bridge member 18, and the truss-like arrange ment of the

braces

10a, 25, at the same time give reinforcement to said frame member where it is most needed; and that the foregoing construction, in combination with the cross-ties 32, provides a triple support for the engines, vertically thereof, to prevent undue bending strains on any of the parts, without interfering with the application of various steam piping arrangements.

hat I claim is l. A geared locomotive frame and engine support including a row of truss-like braces secured at the top and bottom of a member of the frame.

2. A geared locomotive frame and engine support including a row of truss-like braces secured at thetop and bottom of a member of the frame and a bridge member extending longitudinally of said frame member.

3. A geared locomotive frame and engine support including a row of truss-like braces secured at the top and bottom of a member of the frame and a bridge member extending longitudinally of said frame member adjacent the juncture of said truss-braces With the top of the frame member.

4. A geared locomotive frame and engine support including a truss-like structure secured at top and bottom of a frame member and having engine parts mounted thereon, and a support thereabove secured to the engine and the locomotive.

5. In a locomotive having a frame, a boiler, and a row of cylinders mounted laterally of the boiler, a supporting structure for the cylinders secured to the frame at top and bottom,

and a brace between each cylinder and the boiler.

6. In a locomotive having a frame, a boiler, and a row of cylinders mounted laterally of the boiler, a supporting structure for the cylinders comprising a member extending longitudinally of the row of cylinders and secured along the lower portion of a frame member, and a bracing structure for each cylinder including a diagonal member secured to said longitudinal member and to an upper portion of said frame member.

7. In a locomotive having a frame, a boiler, and a row of cylinders mounted laterally of the boiler, a supporting structure for the cylinders comprising a member extending longitudinally of the row .of cylinders and secured alongthe lower portion of a frame member, and a bracing structure for each cylinder including a diagonal member secured to said longitudinal member and to an upper portion of said frame member, together with a brace between each cylinder and the boiler.

8. In a locomotive, an open girder frame member constructed to permit ready access to associated parts, and a truss structure extendingacross the opening and bracing said member at top and botto 9. In a locomotive, an open girder frame member constructed to permit ready access to associated parts, and a truss structure extending across the opening and bracing said member at top and bottom, said truss structure serving also as an engine support.

10. A reinforcing member, for an open type girder locomotive frame member, formed as an engine and crank shaft sup port.

11. A reinforcing member, for an open type girder locomotive frame member, formed as a crank-shaft support.

12. A supporting structure for the cylinders and crank-shaft of a locomotive comprising crosshead guides and a truss structure connected together.

13. A supporting structure for the cylinders and crank-shaft of a locomotive comprising crosshead guides and a truss struc ture connected together, said truss structure having means whereby it may be mounted on the locomotive frame.

14. A supporting structure for the cylinders and crank-shaft of a locomotive com prising cross-head guides and a truss structure connected together, said truss structure having means whereby it may be mounted on the locomotive frame, and serving as a brace therefor. I
