3 Claims. (01, -162) was:

ENT,"

way motor cars and the like, the assembly being comprised of strong and relatively light-weight longitudinal and transverse frame elements'arranged to provide a rugged and durable car frame.

Another object is found in the provision of an 7 improved motor car framecomprised of longitudinal and transverse frame elements, certain of which are of relatively narrow but deep section, so arranged in the frame asembly as to effect a certain degree of flexibility in the assembled frame, whereby to provide for absorption or cushioning of vibrationstransmitted to'the frame through the car Wheels operating on the rails. v

A further object is to provide a railway motor car frame of the characteristics above noted, which may be manufactured and readily assembled at a minimum cost.-

Further objects and advantages will readily appear from the following description when read in connection with the accompanying drawings, in which: l r

Fig. 1 is an assembly elevation in plan; of a railway motor car embodying the improved frame forming the subject of the present invention; Fig. 2 is a side elevation thereof; Fig. 3 is a longitudinal sectional elevation of the car frame, as viewed from line 33 inFig. 1; Fig. 4 is a fragmentary longitudinal section of the frame as taken from line 4- 6 in Fig. 1; Fig. 5 is a transverse section of the frame as viewed from line 5-5 in Fig. 2, with a portion thereof shown in end elevation; Fig. 6 is a transverse section of the frame as viewed from line 6 8 in Fig. 2," and Fig. '7 is an enlarged, fragmentary section of a portion of the frame illustrating certain features thereof, the section being taken along line 'l--'! 'in Fig. 2.

It is of major importance in railway motor cars that the car structure be strong anddurable, yet as light as possible, for the reason asis well known, that such cars are manually transferred to and from the rails at relatively frequent inter vals during use. stated in the objects, the principal purposeof the present invention isto provide such a car frame, i. e.; a light weight, strong and rugged frameassembly. 1,1, 1.;-

. tending longitudinally on either side of the raised Accordingly, as hereinabove Re1ferring'now to the drawings by suitable numerals of reference, there-is provided prefer; ably a. pair of longitudinal frame elements l9 located somewhat centrally {of the car, these elements serving as engine sills upon which is mounted'a suitable car-propelling meanssuch as an internal combustion engine, shown in broken lines at H in Fig. 3. The sills lil which are, by

preference, formed from suitablewood material,

have their corresponding ends l2 secured as by bolts (not shown), to a transverse or cross sill l i'located thereabove and extendingsubstantially the width of the"-car,the cross sill l4 also being of a suitablewood material. Theopposite ends I5 of the longitudinal members'ii! are 'connected in any suitable manner, asby boltinginot shown), to transverse elements it whichfln the presentexample, are preferably angle irons. As clearly appears in Fig. 5, the cross sill M isof stepped. form, havinga central raised portion is 20 providingvertical shoulders iii for a purpose later appearing, and horizontal reduced endportions 2B. Horizontally disposed floor boards'22, ex-

sill portion l8 and substantially coextensively with the length-of the motor car, are mounted upon the reduced sill ends 28 inwardly of their ends 23 (Fig. .4), being secured thereto in any suitable manner, as by bolting-(not shown). Inwardly of their opposite ends 24, the floor boards rest upon and are secured totransverse elements or filler members 26, these members'in turn being secured upon the upper transverse angle iron to.

As appears in Fig. 1, the floor boards providein combination with other elements hereinafter appearing, a tool tray along each side'of the car. "It is to be noted also as an important feature, that. the floor boards secured to the transverse sill l4 and to theupper angle-iron i 6 through the trans verse elements 26, serve to prevent diagonal shi'ft-' ing ortwisting' movement of the. frame.

Secured to: the outerjen'ds of the cross sill I4,

as by bolts 2'l, are brackets 28; providing'supports for bearing members'or boxes 30 in which are rotatively journalled 'theierids of an axle 31." The outer ends of the axle extend beyond the journal boxes for "operative connection to car wheels 32.

The axle 3| is power driven from the engine, I I

through a .suitablejdrive' connection, such as a. belt or chain indicated in broken lines at 36, and apulley or sprocket. 35 operatively secured to the,

axle intermediate-its ends L(Fig.l5,). Acut-away portion or notch 36 is provided in'the cross sill M: to accommodate one passcf the belt or chain.

f -The'brackets .28 :servealso toshpgiort-sidesills 38 which extend longitudinally of the car frame, the portions of the sills engaging the brackets being secured thereto in any suitable manner, as by bolting (not shown). The side sills 38 also engage and are secured near their opposite ends, to axle journal members 39 secured between the ends of the angle iron cross pieces (Fig 6).

' The journal members 39 operatively support the stub-shafts 40 for car wheels 42.

The sides for each of the tool trays hereinabove noted, are provided by relatively thin but wide boards 43 and 44 arranged on edge and extending longitudinally of the frame, the boards 43 constle tuting the inner sides, being secured, as by bolting (not shown), to the shoulders IQ of the transverse sill l4 as appears in Fig. 5. The boards 44 comprise the outer longitudinal sides for the trays. Engaging and extending outwardly from the upper end of each side board 44 is a so-called toe board 46 which is substantially coextensive with the longitudinal extent of the frame; As shown in Fig. 7, the outer margin 41 of one of the floor boards 22 is interposed between the side board 44 and the side sill 3B. The floor board margin 41, side board 44 and-toe board 46 are preferably bolted together throughout the longitudinal extent thereof, as by through-bolts 48. one of which is illustrated in the figure.

The toe boards 46 are structurally braced and supported in part at their opposite ends 50 and 5|, by steel angle members 52 which extend transversely the entire width of the car. Also between the ends of the outer side boards 44 and extending transversely of the car, are" frame strengthening end boards 54, these end boards serving as end walls for the tool trays. Further supporting the toe boards 46 intermediate their ends, are angle brackets 55, each secured to its associated toe board as by a suitable-bolt ,or screw 56, and to the shank of a bolt or stud 51 carried by and projected outwardly of the adjacent side sill 38, the head 58 of the bolt engaging the inner side of the sill as appears in Fig. 7.

As will appear from Figs. 2 and 7,xupon each of the studs 51 is pivotally mounted a brake shoe 59, there being by preference, a brake shoe for each of the car wheels 32 and 42. A suitablenut 59A engaging the end of each stud serves to retain the shoe thereon. The location of the'studs is such that the brake shoes are disposed adjacent the car wheels in a manner toprovide for braking engagement therewith, upon brake actuation. All of the brake shoes may be actuated simultaneously by any well known type of brake actuating mechanism, elements of which are indicated at 60 in Fig. 2, in operative association with a pair of the shoes on one side of thecar. It is to be noted that the brackets serve to transmit to the car frame, particularly to the toe boards 46 and indirectly to the side' boards 44, the brake reaction upon braking actuation of the brake shoes.

As appears in Figs. 1 and 5, the inner longitudinal margin of each toe board is provided with an angle iron 62 whichserves toprevent wear or chaffing of the toe board margin, since these boards serve as foot rests for the car passengers. Further, as shown in Figs. 5 and 6, each of the axle journal " members 30 and 39 is provided with a depending lug 63,and between the lugs ofthe journal boxes onea'ch side of the car is a longitudinal rail-skid 64", preferably comprised of a steel angle iron. The rail skids serve in addition to the well known purpose therefor,

, Fig, 8, the stub posts 14 engage and are secured to the cross sill M at their lower ends, while the stub posts 12 rest upon the upper transverse angle iron [6, and are securely connected to the side boards 43 as by bolting (not shown). The end posts 10 are secured adjacent their lower ends to the side boards 43 and are braced by the adjacent end board 54 and angle piece 52, while the posts H at the opposite ends of the car frame are similarly secured to the side boards 43 and are also braced in a similar manner by the adjacent end board 54 and angle piece 52.

The upper ends of end posts H are connected by a rail 15 (Fig. 5), which may be a section of pipe suitably secured to the posts and serving as a hand rail. Also, at this end of the car, there is provided a storage platform beneath the seat, constituted by horizontal boards 16 arranged transversely of the frame between the inner side boards 43 (Figs. 3 and 5). A board 18 arranged on edge and extending between the posts H provides an end guard or wall for the platform.

As appears in Figs. 1 and 6, the end posts 10 have their upper ends connected by a hand rail 19 which may be a pipe section, the rail being extended laterally of the car frame beyond the posts 10 for connection to the upper ends of additional posts 80. Each of the latter posts is secured near its lower end to the adjacent outer side board 44, in the corner formed by theside board and adjacent end board 54.

The car frame is provided with lifting handles 82 arranged longitudinally on either side of the seat structure, the handles being operatively mounted in brackets 83 suitably secured to the seat posts H, 12 and 14. Also, arranged adjacent the posts 10 and mounted on the side elements 61, is a storage box 84 for tools, etc.

From the foregoing it will now appear that a relatively rigid, strong and durable car frame is provided, constituted by a plurality of longitudinal and transverse elements arranged to provide for some flexibility in the frame, whereby to absorb or'cushion shock and vibrations transmitted to the frame through the car wheels operating on the rails. The car frame, the preferred embodiment of which is hereinabove described, may be manufactured and assembled at a minimum cost, and is of light weight to facilitate car handling.

It isto be understood that the foregoing description relates only to a preferred embodiment of the invention, and that alterations or modifications in the elements and arrangement thereof may be made without departing from the spirit and full intended scope of the invention as defined by the appended claims.
