This invention relates to improvement in railway car trame construction, p zwticu i larly adapted to railway cars intended `for the transportion of sugar cane and like prodby means of hoisting. Y Y

' lt is an object of the invention to provide a bolster'and cross bearer construction in a car traine ot the type described in v-.ihich the top members of the'bolsters or cross bearers act to reinforce and strengthenthe bolster and cross bearer construction of the traine, and at the saine ytime to provide a portionof the cleat Vfloor of the, car.`

Another object of thel invention is to provide a simplified and economicalv way of making a railway car traine bolster in which extra strength may be added to the bolster without a proportionate increase cost thereof. Y o

Other objects and advantages of the invention will appear as the description of the invention, withreterence to the accoinpanyj ing drawings, proceeds, y

In the drawings which show certain preferred 'l'orins of embodiment of they invention:

Figure l is a top Vplanhview of one end of a railway car frame ywith portions broken away to show the details ofthe bolster' conl struction. Y

Figure 2 is a sectional view gapproximate''-` ly on vthe line 2 2 of Figur-el. y p

Figure 3 is a sectional view approximately on the line 3 3 of Fig. l.

Figure l is a sectional viewv of a portion of the car traine and lloor on the line 4 4 of Figure l. Y o

ln railway cars designed to carry sugar cane and the like, which is tobel discharged from the car by hoisting, it is usual to have a cleatiloor extending across the frame `ofthe car, as illustrated in Figures l and The cleats l0 serve to hold the cane, which is supported between the stakesll, a suiiicient di'sv tance above the car traine to enable chains to be passed under Athe cane and between the cleats, in order to enable the hoist the lift the load of cane from the car. n

In previous cars of this construction, it `has been customary to form the bolsters and cross bearers approximately llush with the top of the side sills 1 and of the center sills 2 and to apply the usual top cover plate to the bolster and apply the cleats 10, which areV usually of angle iron' orwood construction,

across the width of thev frame without refer-f and cross bearer construction, eliminate'fthe i usual top cover plate orthe bolster, and Vat the saine time serve the normalfunction of the spacing cleats l0.

Figuresl and 2 illustrate a normal diaphragm construction of'b'olster in which vfour v extend between the side sills diaphragins 3 l and center sillsQ of the car, two at each side of the frame. These diaphragms be of the usual channel construction, having a vertical central portion 3a, with horizontally extending flanges 3b along the top and bottom and flanges 3c along each end, the -end flanges Se being rivetedtothe webs of. the side and 'center vsills l and 2, and the bottom flanges being riveted to the bottom cover plate 5; *VA pair of similardiaphragms 6 extends between the center sills 2 and are secured in position inthe usual manner. To' form the cleat yfloor of thecar over the bolster a channel section 7, extending from side to sideot the car frame, is provided; The web of the channel 7 adjacent each side is rivetedl tothe top flanges 3l. of the diaphragms 3, and the'top ilanges 'of the diav phralgms 6, serving the functions of theusual'itop coverA plate,rand the flanges 7?* of the channel 7 project upwardly above the frame of the car to actas cleats spacing the sugarcane or othcrload'a sufncient disjtance above theear frame to permit hoisting chains to'b'e passed therebeneath. l The use' ofa channel section?, having the vu'pstanding/tlanges 7n lto act as Kfloor cleats, is a substantial improvement 'over prior constructions, tl s one piece channel section performs theffunctions of the top bolster cover plate and also aof two floor cleats, giving a' stronger bolsterthan" the plated'type and stronger cleats than separate cleats and also closes the space between `the bolster diaphragms for the full width of the car frame, thereby preventing water and material from falling therethrough onto the car tracks. l

A similar ychannel ironsection 8, having upstanding flanges` 8a acting as spacing cleats, may be located over a cross bearer lll which may be of any preferred construction and is illustrated as comprising a pair of Ychannel diaphragms 9a extending between the side and center sillsV 1 and 2, and a channel diaphragm 9b between center sills. l

The channel member 8 is preferablyV riv eted to the top flange of the diaphragms 9L and 9", and due to greater. strength ofl It will be understood that a channel meinber having vertically extending flanges' can be used as floor cleats and also as the top cross member of either a bolster or a cross ei' vi vari us oti r co s ru i bear y th o Lle n t ct ons of holsters or cross bearers than those specif ically illustrated and vthat all these Amodilications and changes are contemplated within the spirit of this invention and the lscope of the appended claims.

IV hat I claim as my invention is:

l. In a railway car frame of the Cleat floor type, side and center sills, cleats exy tending across the car frame, a double dia phragined bolster` with a channel Vtop cross member extending across the frame with the flanges of the channel projecting upwardly above the sills.

2. In a' railway lcar frame of the cleat floor type, side and center sills, cleatsextending across the car frame, a double diaphragm bolster and a channel member prof vidingv a pair of upstanding cleats withV a web of the channel member extending between4 the diaphragms of the bolster and lsecured to the top flanges thereof.

3. In a railway car frameY of the cleat floor type, side and center sills, cleats extending across theV car Atrame, a double diaphragmed bolster with a channel top cross member extending across` the frame with the flanges of the channel projecting upwardly above the sills, and one or more cross bearers,'each with a channel top crossinember extending across the frame with,

the car frame secured to the top flange of menare the flanges of `the channels projecting upwardly above the sills. n'

l. In a railway car frame of the cleat floor type, side and .center sills, cleats extending across the car frame, including cleats formed of channels having the channel webs lying horizontally and riveted or bolted to the sills and having the flangesv protruding upwardly forming cleats to support the load. 'd

5. In a railway car frame of the cleat j floor type, side and center sills,y cleats extendingac'ross the car frame, including' cleats formed of channels having the chanfnel webs lying horizontally and secured to the side sills and having the flanges protruding upwawll'y to support the load, and

a double diaphragmed bolster with a channel top cross member 'extending across theA frame with the flanges of the'channel proy jecting upwardly above the sills.

6. In a railway car frame of the .cleat floor' type, a plurality of cleats extending :from side to side of the car frame andchannel sections', each provided with a pair of upstanding flanges acting as cleats, located above the bolsters and cross bearers and se-` cured thereto. f y Y 7. In a railway car frame comprising side and center sills and vhaving double dia# .phragmbolstera a channel member extending from side to side of the car frame overv the bolster diaphragms and spacing the distance therebetween, thev web of the channel .member being secured to the top flange 'of each bolster diaphragm with the flangesof the channel projecting upwardly.l f

8. In a railway car frame of the type described, the side and center sills extending longitudinally of the frame, diaphragm holsters extendingl therebetween and a chan-- nel member extending across thewidth` of the bolster. Y

9. In a railway car frame of the type described, side and Vcenter sills extending longitudinally. of the frame, double plate holsters extending.therebetween and a channel member extending across the width of the car frameV over the bolsters and between the vplates of the bolster secured tothe top ofthe bolster plate.' i

vIii-testimony whereof` I have alfixedmy 1 signature to this specification.
