RAJ'LWAY UNDERFBAME Application led November 10, 1930. Serial No. 494,781.

My invention relates to railway rolling stock and consists in a novel underframe structure particularly adapted for use in locomotives'of the oil electric type which must carry heavyv internal combustion motors and a supply of fuel oil for the same.

riveted'or bolted together to form j ints which The main objects of my invention are to form a 'strong' light underframe structure adapted to carry motors of the class referred to and to provide fuel reservoirs therefor and to maintain a. low center of `gravity for-theV structure.

It is/also an object of my invention toproduce the underframe in an integral structure, preferably madeof a`. single casting, whereby the-rigidity of the frame will be securedwithout the necessity .ef frequent inspection and repairs, such as is required for built-up structures having 'a number of parts work loose.' Incidentally, such joints require additionaljianges on the connected members,

the metal of which flanges is not used as effectively as in a cast structure where masses of metal need be used only where they con- Y tribute necessary strength to the structure.

Another object of my invention is to pro- Y vide a suitable support for the cab.

These and other detailed objects of my invention are attained by the structure shown in the acompanying drawings in which- Figure 1 is a top view o embodying my invention.

AThe underframe in ludes four main longitudinal vertical .members or

sills

1, 7 1, 2,2.

, between sills .1 may an underframe These sills carry the majorvportion of the .ate the holsters and

sills

1 and 2 on one side of the longitudinal center line of the locomotive have the lower portions of the deepened parts connected by a corrugated web '4: lformed integrally therewith. Transverse members 5 brace the

longitudinal members

1 and 2 and form, with the latter, side walls of oil reservoirs or tanks Rlocated on each side o f the center of the frame. The underframe sills are provided with upper flanges 6 formmg top wall elements of the reservoirs andpreferably completed by means of plates P which are welded to the edges of flanges V6 to complete the reservoir top wall. A conduit betweenV reservoirs R provided by the elements 7 whereby the liquid in both reservoirs is maintained at the same level. These elements 7 also fromasubstantial tie between the pairs of

sills

1, 2 on opopsite sidesof the unlferframe.

greater capacity is desired, the space be utilized as a reservoir, -the horizontal we s orbraces 8 being made continuous and .suitableopenings provided inthe sills 1 to permit liquid to pass between the reservoir outside of the sill 1 and the 'spaceinsideofthesillL' n, Themotor's will..be mounted on the bed preferablyby bein bolted tothe an'ges 6. To' free the holdinggbolts from undue stresses resulting from the starting and Stopping of the locomotive, I provide lugs 9 which form stops for engaging the ends of the motor frame. I show such a motor at M (see-Figure 6) with its base orlower crank case or voirs R.

The frame also includes box shaped end `sills 10 and the 1 are extended downwardly at their ends to provide draft sills or housing forming-members 11 which, prefer# f ably, have the draft gear guiding elements 12 and stops 13 integral therewith. Plates v25 constitute platform-like extensions of the Vtop walls of sills 10 and the ends of plates 25 are recessed and depressed to provide steps 17.

Side members 14 extend from platform to platform and are supported from sills l.2 by integral brackets 15. A suitable pad 16 extends all around the underfram'e on members 14 and plates 25 and is adapted to be finished to mountthe superstructure.

Each of the holsters 3 comprises a top member 18 and vertical walls 19 and 2O which member andgwalls extend substantially from end to end of the bolster. A bottom member 23 extends between walls 19 and 2O and from theside bearing-24 on one side of the underframe to -the side bearing 24 on the other side of the underframe. This provides a bolster having a box shapebetween the side bearings and having an inverted U shape outwardly of the side earings. This construction permits a brake cylinder C, or other equipment mounted on the truck beneath the bolster, to project upwardly below the level of the bottomof the bolster and between

walls

19 and 20. It is desirable to reinforce the

bolster walls

19 and 20 with suitable flanges and these are indicated at 26 and 27 (see Figure 8) By turning flange 26 outwardly of the bolster side wall 20, I increase the clearance for the rear end of brake cylinder C so that it does not contact with the bolster wall 20 when the truck pivots on the unf.

derframe. By turning flange 27 inwardly of the bolster side wall 19, I increase the 'clearance for the upper end of the brake lever L towhich the brake rod B is connected. This construction facilitates the locationv of the bolster wall 19 as near as possible to the end of the'car, in view of the upstanding brakel lever L, the position of which is determined by the location of the truck which, of course, is pivoted to the underframe through the centerv plate structure 29 located as near the end of the car as is practical in view of the draft gear. A

As a result of constructing a bolster adapted to meet these conditions arising from the relative position of the truck center plate and desirable-that the bolster brace

longitudinal sills

1 and 2 throughout their depth and therefore the portions of the bolster adjacent these sills should beas deep as these sills. Since these sills extend downwardly below the level of the top of the brake cylinder and associated parts, I have provided upwardly extending recesses in the lower parts of

walls

19 and 20 as indicated at 28 in Figure 5.

The above description includes a number of details of construction which may be varied substantially, or omitted from the undery frame, without affecting other features of my invention and I refer particularly to the .extent and direction of the corrugations in websA, -to the offset relation of the center plate and bolster, and to thearrangement of the pads for supporting the ends of the superstructure. Obviously these features could be changed and I desire to include within the scope -of my invention all modifications of the construction which come within the scope of my claims.
