For convenience the constituent parts of the frame are hereinafter described with reference initially to the front end of the frame shown at the left hand of Fig. I, and thereafter proceeding along the frame to the right hand of Fig. Il.

With particular reference to Figs. I and VH, it Will be seen that the longitudinal side members 1 converge slightlytoward the end of the frame, terminating in the transverse Wall 2 above an end-frame section 11 Which acts as a draft gear housing. The side members 1 are also integrally connected at this end of the frame by bottom plates 12, top plates 13 formed to accommodate a heating boiler at 14, and the stiiiening member 4, these members 1, 2, 12, 13 and 4 forming an end compartment 50 for Water storage eX- tending Afrom one side of the frame to the other. Suitable openings in the top of the Water storage compartment 50 are provided at l and 16 to give ready access to the compartment and to enable the illing of it with Water and the Withdrawal of water therefrom.

Additional openings 17 at the side members 1 are provided so that sand cores may be supported Within the Water compartment during the casting operation and later removed when the casting has been completed. The openings 17 are subsequently covered with plates and sea-led to render the compartment water tight. At the bottom of the Water compartment and running longitudinally ercof are a pair of parallel stittening mems 18 with openings 19 permitting the passage of Water from one side to the other. At the top of the Water compartment 50 and immediately beneath the heating boiler support 14, there is a longitudinal partition 2O running centrally of the frame, and forming a trough to accommodate chains passing from a hand brake chain shaft at 21 at the front of the boiler to the brake cylinders supported on the pads 22.

Directly beneath the annular support 14 for a heating boiler therelis a cross-tie 3 which serves also as a body bolster and has a center plate 23 adapted to bear" upon the front locomotive truck. As shown in Fig. VIII forward of the cross-tie 3 there is a transverse stiening member 24 which trans- Jfers the Weight of the boiler to the longitudinal side members 1. The combined Weight of side members 1 and heating boiler is transferred to the center plate 23 of the bolster 3 by diagonal stiiening members 25.

Bisposed on either side of the Water com-4 partment at this end of the frame are two cylindrical oil tanks 26. The longitudinal side members 1, which form the sole partition between the oil tanks 26 and the Water compartment 50, have portions 27 of part cylindrie shape constituting a part of the Walls of the oil tanks 26 and of the Water compartment. Dia onal braces 28 and 29 reinforce the longitu inal side members 1 at their portions which comprise the side walls of the Water compartment. The oil tank Walls are formed with cored openings 3() to permit the escape of foundry gases during casting, these openings being subsequently closed y filling With cast steel Welded in place or by Welding plates over the openings. The oil tanks 26 are also cast with their forward ends open, these ends being subsequently closed by reservoir heads 31. At the other end each tank has an opening 32 eccentric to its c lindrical Wall. The openings at the endbs of these tanks permit the support of sand cores therein during the casting operation and the subsequent removal of the sand cores.

Between the cross-tie stifening member 4, which also serves as an end Wall for the Water compartment, and the cross1tie 5 are the sup ports or pads 22 for the accommodation of brake cylinders, and beneath the pads 22 is a Webbed projection 33 comprising a bearing for the fulcrums of driver brake levers.

The intermediate frame section comprises the longitudinal side members 1 and crossties 5, 6 and 7. Throughout this section the side members have portions of substantially box-shaped section as indicated at 34 with a superimposed angle member 35 having a flange 36 turned inward. Flanges 37 formed at the top of the oil cylinders 26 and air cylinders 38, to be later referred to, are in the same plane as the top of the box-shaped portions of the side members 1, and these parts together form a support for outside deck plates running longitudinally of the locomotive.

Cross-ties 5, 6 and 7 of the intermediate frame section, as shown in detail in Figs. X, XI and XII, are provided With pads 39 for engaging motor nose clamps, the pads 39 being disposed to provide a three-point suspension for each electric motor frame. Each cross-tie 5, 6 and 7 is also provided with biurcated brackets 40 for supporting the clog hangers of the driver brakes. Adjacent to the areas in which the motors are suspended the side trames 1 are provided with pedestals 41 for the axle journal boxes of the driving Wheels, the bottom ends of the pedestals 41 being connected by longitudinal members 42 which are cross-connected by means of the cross-ties 5, 6 and 7.

At the rear end of the frame, as shown in Figs. H and IV, the longitudinal side members 1 converge slightly, terminating in the end Wall 10, above an end-frame portion 43 which comprises a draft gear housing similar to the draft gear housing 11 at the front end of the frame. A. second Water storage compartment 51 is formed at this end of the frame bounded by the longitudinal side mem` bers 1, the end wall 10, bottom plates 44, the

teasers combined cross-tie and tank wall 8, and the top member 45.

The box-shaped cross-tie 8, which also acts as an end wall for the water compartment 51, is provided with depending perforated arms 46, .as shown clearly in lFig. lV, adapted to carry fulcrum pins for spring-rigging equalizer beams which -converge towards a cross-head guide which is positioned within the cross-head guide support 47. Diagonal stiening members 48 integrally connect the cross-tie 8 with the support 47 and form a cavity beneath the end of the water compartment through which equalizer beams pass to the equalizer cross-head guide. A number of openings indicated at 49 in the walls of the box-shaped cross-tie 8 permit the passage of water to the wall 52 which forms the end of the water compartment 51.

The cross-tie 9 comprises the equalizer cross-head support 47 and stiiiening plates 55 connectinof the support 47 with the side members 1, there being a large opening 53 and a number of smaller openings 54 permitting the passage of Water from one side of the stiiening plates 55 to the other. A pair of parallel longitudinal stiifening members 56 provided with suitable openings 57 connect internally of the water compartment 51 the cross-head guide support 47 with the end wall 10. A number of openings 58, 59, 6() and 61 ot various sizes and shapes in the top member of the water compartment 51 give ready access to the compartment and provide means for filling the compartment and Jfor withdrawing Water therefrom. Additional openings 62 serve the saine purpose as the corresponding openings 17 at the other end of the frame.

Compressed air tanks 38 are disposed at the sides of the water compartment 51 in a manner similar to that in which the oil tanks 26 are incorporated in the frame at the other end, and it will be apparent that many other structural features of the rear end of the frame correspond to those already described with respect tothe front end.

rlhe ent-ire structure illustrated in the drawings with the exceptions of the heads 31 and 63 for the cylindrical air and oil tanks comprises a one-piece integral casting so designed that tlie operation of assembling the complete locomotive equipment upon the frame is greatly simplified and the number ot fastening means, such as bolts, rivets and the like normally required for assembling, is considerably reduced.

The frame possesses many structural advantages both with respect to the distribu tion of stresses and strains and with respect to strength and rigidity in proportion to the amount ot' metal used. Numerous joints and supports for equipment, normally made as separate parts and requiring drilling of the frame and the use o fastening bolts, have been incorporated in the casting with obvious attendant advantages.

While one specific embodiment of the invention has been described in some detail, it will be apparent to those skilled in the art that various modifications and changes may be made in the form of the frame as described without departing from the spirit of the claims hereto appended. lt will also be apparent that certain features ot the invention may be used to advantage without a corresponding use of other features.
