DROP-BOTTOM DUMP-CAR.
SPECIFICATION forming part of Letters Patent No. 780,762, dated January 24, 1905.
Application filed July 11, 1903. Renewed December 24, 1904 Serial No- 238,224.
To all whom it may concern;
Be it known that I, Srnnonn OTISJL citize of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Drop-Bottom Dump-Cars, of which the following is a specification.
The principal object of the invention is to provide a simple, economical, and eflicient drop-bottom dump-car with means by which all of the load therein may be automatically discharged.
The invention consists principally in a drop bottom car in which there are combined a supportingframework and a drop -bottom' therefor formed of a plurality of swinging sections having independently-movable rearand front portions pivotally secured in position to each side of the longitudinal center of the car.
The invention consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed In the accompanying drawing the figure represents a cross-sectional elevation of a car as it appears when constructed in accordance with these improvements.
In constructing my improved car I prefer to use a supporting-frarnework' consisting of 'a plurality of longitudinal sills a, centrally disposed, and a plurality of transverse deckbeams b resting thereon and secured thereto in any desired or convenient manner, thus dispensing with all side sills below the upper level of the deckbeams and providing a-free and unobstructed discharge-opening, as will more fully hereinafter appear. Secured to this supporting-framework are side-boards c and end-boards (Z, which form the sides and ends of a gondola or other car requiring side and end boards or walls.
To form a flat-bottom car which will also be a drop-bottom car, aplurality of swinging sections is provided and pivotally secured .in
portions 6 and front portionsf, independently and rnovably mounted upon the same pivotal points or shafts g. It will be noticed upon examination of the drawings that where the parts are laid in a flat plane the rear portions engage or overlap each other and the forward portions extend forward to the extreme sides of the car. In opening, the forward portion is first released and drops part way to discharge a portion of the load. Then the heel 72, of its bracket contacts the forward portion or adjacent wall of the bracketc' of the rear part and assists to move or raise such part during the discharging of the remaining load to an A- shaped discharging position. To open and close these doors, rock-shaft mechanisms are provided, which, by means of the chains is, are connected to the free ends of the swinging sections and used in the ordinary manner to open and close such doors.
A stop-block Z is provided, as shown particularly in the drawings, and arranged between the deck-beams so as to permit one of the rear swinging sections to contact and rest on the same when in its flat position, and thus assist in carrying the load.
I claim 1. In a drop-bottom dump-car, the combination of asupporting-framework,and a dropbottom therefor formed of a plurality of swinging sections having independently-movable rear and front portions pivotally secured in position to each side of the longitudinal center of the car, substantially as described.
2. In a drop-bottom dump-car, the combination of a supporting-frame'work,adrop-bottom portion formed of a plurality of swinging sections having independentlymovable rear and front portions pivotally secured in posi' tion at each side of the longitudinal center of the car, and shaft mechanismsone arranged at each side of the longitudinal center of the car upon which such swinging sections are pivotally mounted, substantially as described.
3. In a drop-bottom dump-car, the combination of a supporting-framework provided with upwardly-extending side and end boards,
nnrssunn and a drop-bottom therefor formed of a pluand substantially A-shapcd discharging porrality of swinging sections pivotally secured tions in open position, substantially as de- 10 to the framework of the car at each side of the scribed.
longitudinal center, each swinging section bei L i T i w w r 5 mg formed of two lndependently-movable SPEBLER O'nb' portionsrear overlapping portions and for- WVitnesses:
