Beit Aknownthat we, CHARLES A. LIND- s"rir 'fi,\i, ol Allegheny, and JOHN F. Srnnrn, of Avalon, Allegheny county, Pennsylvania, have invented a new and useful Steel Car,oi" which the vlollowir'ig is a ilull, clear, and exact description, reference being had to the acernnpanyingdrawings, 'forming part oithis specification, in Which- 'lfigure 1 shows in plan view the underi'raine oi a car embodying our invention. `Fig. 2 is a side elevation thereof. Fig. 3 is a vl-,irtical section on the line lll lll of Fig. l. Fig. 4 is a eross-sr-retion on' the line IV IV oi Fig. 1. Fig. 5 is a detail View showing a inodiiication. Fig. o is a top plan view showing a niodiiiel l'onstruetion. llig. 7 is a longitndiiizfil section on the line Yll Vil of' Fig. 6, and Fig. 5% is a side elevation thereof.

(iur invention is designed to provide a steel ,ear-'fram e for street-railway ears having end platforms at a lower level than the main i'rarne of the car-body and to make the con-, struction ol great strength and durability.

"lhe preferable forni of our invention is shown in 'the drawings, in which 2 represents the bolster, 53 the end sill, and 4 1 the side sills, oi the ear-trarne, which are made ol suihibly-llaiigerl nietai beams or pieces.

'.lhe platiorin-i'ranie has inain platformsilis 5 :')gwhich extend forwardly of the'cnd sill 2% at a lower horizontal plane. At or near the end sill'tliese sills 5 5 are curved upwardly, e, to the level of the side sills and are iiixed thereto, extending along the side sills to :i point back of the bolster, thus reinforcing the s e sills and .strengthening the underirarne of the car at the bolster. VEach of the platiorrii-sills 5 can be made in anpintegral pi'eee or, as shown in the drawings, in sections riveted together. They are supported by metal brackets 7, which depend from the 'end sills and terminate preferably in C-shaped supports, which embrace and are lixedto thesills 5. rlfhe entire weight ofthe platforrn can thus he carried from Vthe end sill by the sills 5.

The remainder of the platform-frame is composee` ot beams 8 8 and,9 9, which are iixed to the under side of the end sill 3 at their inner ends and extend thence to the platform Specification ef'Letters Patent. Application tiled August 12,19-03. Serial No. 169,246.

is bent downwardly or flanged at its forward edge and is fixed to a marginal angle 12 either on the inner or outer side thereof. This ailords a still and very strong end construction to the plat'l'orn'i. Fig. 5 shows the angle 12 fitted to the inside of the plate 11.

ln the ligures on the third sheet of the drawings the end sill 3! is set at a lower level than the side sills and the platformdieams 9 Q extend baell to the bolster as continuations of the center sills c e and are supported iroin the end sill by brackets 7 Within the scope ot our invention as defined in the claims the construction may be modified in various ways, since What We claim isq 1. A car-frame having diagonally-extending metal platform-sills suspended from the undertraine of the ear, the rear portions of said sills being bent u wardly and extending along theside sills oil) the underfra'me to a point back ol the bolster, thereby reinforcing the side sills and strengthening the underframe ol the car'at the bolster; substantially as described. 2. A- car-frame having metal platf0rinsills suspended from the underframe of the ear and extending in a direction obliquely to the center line o fthe car, and a flanged platforni end sill overlyixw the forward ends of the platforrn'- sill and having a .'rnarginal flanged anglesecured thereto; substantially as described.

3. A car-frarne having an end sill, side'sills and bolster, metal platformsills below the level of the 'side sills extending upwardly along the same to the bolster and fixed to the side sills, said platform-sills being sup ortedon open-sided brackets attached to t e end sill substantially as described. y v

4. A car-frame having flanged metal latforrn-sills below the main underframe o the car and suspended therefrom, said Vplatformsills extendlng upwardly and iiied to the earrame back of the end sill, and C-shaped brackets suspending the platform-sills"fromthe end sill; substantially as described.

5. A car-fraine having 'a platform, and a IOO .and a marginal'flanged`beamg sgbstantially' .set ourvhands..
