4 Claims. 1

The invention relates to railway vehicles and hicles, such as electric locomotives.

In one type of electric locomotive used here-V tofore, the draft gear is removed downwardly from the draft gearpocket in the vehicle bed. The brake rigging and other equipment just below the draft gear pocket must be removed before dropping the draft gear, which may require shop facilities not usually found in the ordinary running shed or inspection pit. Also, the draft gear pockets at the ends of the bed are connected by a center sill to carry buffing and pulling forces from one end of the bed to the other. Separate sand boxes may be attached to any convenient part of the bed.

One object of the present invention is to remove the coupler and draft gear from the draft gear pocket longitudinally of the bed and Without removingthe brake gear and other equipment. I

Another object is to construct the draft gear housing with an integral bottom web to prevent the side walls from spreading laterally of the truck bed.

Another object is to transmit the buffing and pulling forces from one end sill to the other through the bed side members, instead of through a center sill.

Another object is to form sand boxes integral with the truck bed at the juncture of the side members and the end sills, thereby forming the sand boxes as part of the bufling and main carrying members.

Another object is to construct the sand boxes to obtain maximum strength without affecting their functional characteristics.

Another object is to provide a lighter, more compact driving truck bed.

Other objects will be apparent to those skille in the art from the following description and accompanyin drawings, in which:

Figure l is a top view of a railway vehicle driving truck constructed according to the invention and with portions of the truck bedcut away to show the construction more clearly.

Figure 2 is a side view of the truck showing one of the motor mounting in vertical longitudinal section.

Figure 3 is a horizontal section through the couplin structure and draft gear pocket taken approximately on the line 3-3 of Figure 2 and drawn to enlarged scale.

Figure 4 is a vertical longitudinal section through the coupling structure and draft gear pocket taken approximately on the line 4-4 of Figure 1 and drawn to enlargedscale.

Figures 5 and 6 are vertical sections through a sand box at the left hand end of the truck in Figure 1 taken approximately at right angles to one another on the lines 5-5 and 6-6, respectively, and drawn to enlarged scale.

Figures 7 and 8 are vertical sections through a sand box at the right end of the truck in Figure 1 taken approximately at right angles to one another on the lines 'l'l and 88, respectively, and drawn to enlarged scale.

The truck includes wheel and axle assemblies l and journal boxes 2. A truck bed has end sills 3 and side members 4 connecting the end sills and provided with depending pedestal legs 5 for receiving journal boxes 2 between them. Electric motors E are secured to the axle housings and drive wheel and axle assemblies I. A bolster 6 extends laterally of the truck between the side members and has a center plate 1 for mounting a car body center plate (not shown). Sand boxes 8, 9. [0, II at the corners of the truck bed are cast integral therewith at the junctures of v the side members and end sills and form the sole tial portion of sand boxes 8, 9 extend into end sill 3 and the box end Walls [6, [1 form reinforcing ribs for the associated sill 3 and side members 4, respectively. A sand filler pipe l8 extends upwardly and outwardly of the bed from top and outer side walls [2, l4 and an outlet l9. in bottom wall I3, provides for discharging sand to the rail.

Sand boxes I0, ll, at the right hand end of the truck bed (Figures 1, 2, '7, 8) extend diagonally between the associated end sill 3 and side members 4. Each sand box [0 and I l forms a hollow receptacle havin a top wall 20, an inclined bottom wall 2|, an outer side wall 22, an inner side Wall 23, and

end walls

24, 25. Top wall 20, bottom wall 2| and

side walls

22, 23 form the bounding walls of the corresponding truck bed portion and

end walls

24, 25 form reinforcing ribs for the truck bed portion. A sand filler pipe 26 extends upwardly and outwardly of the 3 truck frame from top wall 20 and outer side wall 22. An outlet 21 in bottom wall 2| is provided for discharging sand to the rail.

Sand boxes 8, 9, H], H form part of the bufiing and main carrying members. This saves weight and at the same time accommodate the sand boxes without, in any way, reducing the load carryin sections.

Sill 3 at the right hand end of the trucklFigures 1 and 2) has an articulated connection 28 to an adjacent truck (not shown) A draft gear pocket 29 is formed in end sill 3 at the left hand end of the bed'as a-structural part thereof and includes integral webs forming the top 45, bottom 46, and side-walls.41, 48-of the pocket. Draft gear pocket 29 extends :longitudinally of the truck and opensforwardly of end sill 3, at 30, and projects inwardl'y'of transverse, vertical wall 3| of the end sill, substantially abreast of the adjacentpedestal leg 5 and beyond brake hanger brackets '51.

' A draft gearl32 is received in,pocket'29 and is held therein by follower stops 33Lsecured to the side .walls of the draftgear pocket by retainer bolts34. A coupler '35has a head .38 extending forwardly of end sill 3 and has a shank 38 extending intopocket 29 andsecured by a key 31 to the draft gear. A filler block39 is bolted to end sill 3 in pocket'29 adjacent opening 3-8, and a wear element '49 is dowelled to filler block 39 andsupports the outer end of coupler 35.

Coupler '35 and draft-gear 32 may be readily removed from draft gear pocket 29 through opening 38% follows:

'Keyf3l is removed and coupler 35 is withdrawn through opening 30 from pocket 29. Element 40 is'lifted from filler block 39 and filler block 39 is-unbolted from-end sill 3 and both are removed through opening 30. A fixture (not shown) of any suitable kind; is attached to the outer end of the draftgear to compress it vsufliciently to relieve the pressure on follower stops 33. Retainer bolts- 34 then are-removed'and follower stops 33 are withdrawn through opening 30. pression of the draft gearis eased by: releasing The a comthe fixture and the fixture and draft gear arere- -moved through opening 30.

With this arrangement, :it is unnecessary to remove a brake beam 4| directly below draft gear :pocket --2 9 and associated brake-gear 42 43, "44 as would be'necessary if thecoupler and draft gear were removed from-the draft gear pocket downwardly-from the truck bed.

Furthermore, the draft gear pocket may be provided with a-housing that-completelysurrounds the draft geanand integral bottom web 46 makes possible a lighter structure for the same strength as compared to-the-structures used heretofore where the bottom of the'draft-gear pocket wasopen or was provided'with a removable wall-so that the draft'gear and coupler could be dropped through the'bottom'opening. Ifdesired, the shaft for brake lever 49 may-beyjournaled in bearings 50 integral with and depending from bottom'web 46 and side webs '41, 48.

-allemb0diments of the *invention but the structure may'ibeimodifiedsubstantially without departing from the spirit of the invention, and the exclusive use of such modifications as come within the .scopeof the claims is contemplated.

What claimed is: '1. :In :a railway vehicle truck bed, an end sill :-member, a.;side member, and a' sand box includinga -hollow receptacle having its walls extendingdiagonally between and formed integral with said inembi's'and adapted to transmit between said me'mbers draft and bufling forces applied to the truck.

-2. In. a railway vehicle-truck bed,: end sills, side members, .dia'gonal imembers integral with and forming the 28018 -.connections :between :the end .sills and .side members and :each comprising a sand box.
