i freight cars and its object is to increase the.

To allwhom 'it' my concern;

i itknown that I. JAMES S. ANDREWS, a ci-t-lzen of the United States, rresiding at New York city,v in the county of New York 'and Sta-te of New York, have invented new and use-ful Improvements i-ii Iireight-Cars7` .of which the followingl isv a specification.

This-.invention relates to improvements in I capaxzityofthe car 1n proportion to its length.4

My inventiinfcontemplates .increasing the capacity" da car of givelrlength or main i 'tiuningt-h'e capacity and: reducing'the length 16' of the ear.- I f a car of a` given length has its capacity increasedA -the length of a ltrain required t-o transport a given quantityo freight 'wil-lbe correspondingly sliortened; and the same is truc if cars are shortenedin?. length while st-ill maintaining their former general expense of equipping, maintaining and operatin a railroad, lin sofar as trans 4portation of eight is concerned, the invention has other advanta s which will'be apparent to railway officials and employees.

. A tmong such` advantages may be mentioned A,ais

" the fact that a freight train made up cars embodying my invention requires less room on a siding than if made up with ordinarycars carry-ing theV saine quantity of frei ht. Consequently'when a freight train has en run on a siding to permit a through train to pass, there is less likelihood tliat the rear car of 'the freight train will be left rojecting'"`in the path of the through train lltrnia'y als =be mentioned that my inventioiif-'gre'atl facilitates the loading and un- ']l'ie fin'v'ention also has foi its object to provide a freight car of strong and substan tial construction a-nd lar capacity liaiing an underfraine compose of standard sectionsconsisting of steel cast-ings securely and :"-rigidly fastened together.

Referring. to the-drawings, the side sills consist of two end sectioi'is 8 and a-central section 9, these sections being alll preferably made of' cast steel and rigidly Secured together at their adjacent ends.4 Atreach endI of the frame is a draw-bar sill 10 suitably foi-ined to receive the draw-bar and its attachments. The draw-bar sills are provided projections 12 on the side sills and f orm. the ody holsters and also with side projections 13 to-albut against side projections-14 on the side sills to form the end sills. drawbar sills has a air of parallel projetu of the U-shapedcenter sillv 16 isl secured.

preferably made of cast steel and they may' be connected together in variousways but in order to provide for the proper lvstrength and t0 secure the sect-ions together in a firm and rigid manner I prefer to employ wedge shaped tieplates overlappingthejoint-s and jasten'ed to the sections'by bolts or other suitable fastening means as set forth in my application Serial No. 394,790 filed Scpteni- (secured together by wedge plates 17 (Fig. (-3), the end sill rejections by wedge plates 51S (Fig. 5), the lster projections by wedge plates 19 (Fig. 6) and the center sill to the The central sections i9 of the side sills are deeper than the end sections and. the latter gradually'increase Vin depth at'8 from the iolster to their inner ends to make a flush :side sills T). lCast steel transoms 21 are supported on the flanges 22 at the botthe bot-tom of the'ce'nter' sill and the 'dra-wbar sills and these transoms are deeper -a-t their -inner ends than at their outer ends and have their upper edges provided with a plurality' ofvste s 24 to support the stringeis 25 (Figs. 54)). g,

. Between the flooring 27 at the'central part of the car and thehorizontalj flooring 26, 26 at the end s of the car the flooring'28 is also inclined from'the Lcenter sillto the 'side sills Fig. 7). l .Thus the car .is provided with a flooring which is horizontal at the' ends of the car and depressedvbetween thexends of the car, the depressed f'part being high inthe longitudinal. centeno the car (but not so -high as the flooring? at'the' ends. of. the car) and inclined-downwardly and'ontwardly to the bottomof the side sills. 1

The sides and ends 29 of the car may be made of sheet metal supported by uprights 30 fastened to the sidesills. To facilitate the removal offreight `from the 'depressed .parts at the center of the car I prefer to' provide one orV more doors 31 in each side of the car 'of any suitable construction., In the drawings I have 4shown two sliding doors in each side of the car connected b chains 32 with ratchetmechanism 33 for li ing them. Any v kind of door and any kind of lifting mechanism'suitable for'the purpose may b'e employed.

vMy invent-ion increases the capaclty vof a l car tothe extent of the capacity of the depressed bot-tom thereof and 'at the saine time the novel construction of the underfran1e in 4cast s tee1 sections rigidly and securely fasi tened 4together providesa strong and sub stantial car capable of'sustaining the weight of the additional freight which vmay be car-l ried.v Furthermore the, interior of the car is not 'obstructed rbygirders -or braces which would interfere with loadin and unloading.

It is welllmownthat t of cars but my invention enables the increase of the capacity of a-car'without increasing its height or width and .also enables the reduction of' thei height fand width of a car' without reducing its capacity.

What I claim and desire-to secure by ters Patent is 1.` A floor for aA railway freight carhoris zontal at the ends of the car, a central part lower than the ends, -reversely inclined parts connecting the central part and the ends, the
