DUMP-OAR.
v SPECIFICATION forming part of Letters Patent No. 780,761, dated January 24, 1905.
Application filed July 11, 1903. Serial No. 165,077. i
To all whom, it may concern:
Be it known that I, SPENCER OTIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Dump-Oars, of which the following is a specification.
This invention relates to that class of dumpcars which is provided with drop-bottom portions formed of a plurality of swinging sections pivotally secured to the supportingframe of the car, and particularly to the means by which said swinging sections are opened and closed, all of which will more fully hereinafter appear.
The principal object of the invention is to provide a drop-bottom dump-car with simple, economical, and eflicient fluid-pressure-actuatable mechanism to open-and close said dropbottom:
The invention consists principally in a dumpcar in which there are combined a sup portingframe, a drop-bottom therefor formed of a plurality of swinging sections pivotally secured thereto, mechanism arranged to move forwardly and backwardly under each swinging section to open and close the same, and fluid pressure mechanism connected therewith to operate the said door-operating mechanism.
The invention consists, further and finally, in the features, combinations, and details of construction and arrangement hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a detailed plan View of a portion of a car constructed in accordance with theseimproveing-framework having a plurality of longitudinally-arranged center sills a and transverse at their inner edges. swinging sections whenever it 1s desirable so deck-beams 6, preferably provided with side and end boards a and d, extending upwardly therefrom. This frame portion is further provided with a floor portion formed of a centrally-arranged A-shaped apex e and a dropbottom formed of a plurality of swinging sections f, pivotally secured to said frame at each side of the longitudinal center of the car and To open and close these to do, a movable bar g is preferably slidingly mounted under each swinging section and carries antifriction-rolls k in engagement with trucks c'on the under side of each swinging section. To operate these. sliding bars forwardly and backwardly in their trackways j, a fluid-pressure cylinder is is provided, having a reciprocating piston-rod Z extending out through each head thereof. A bell-crank lever m is pivotally mounted on a stud n,'so that one of the armsmay be contacted by a tappet-collar p on said piston-rod and bevibrated thereby in either direction. A link (1 is also provided and pivotally connected with the said sliding bar and the other arm of said bell-crank, the arrangement of parts being such that as the piston-rod reciprocates the sliding bar 9 is moved backwardly and forwardly under each swinging section to open and close the same. Combined inlet and outlet pipes and t are provided for each end of the fluid-pressure cylinder and preferably connected with a source of compressed-air supply, which is essential to reciprocate the piston u, and thereby the piston-rod.
I claim 1. In a dump-car, the combination of a supporting-frame, a drop-bottom therefor formed of a plurality of swinging sections pivotally secured thereto, mechanism arranged in engagement with the swinging sections and movable transversely of the car for operating such swinging sections, and fluid -pressure mechanism connected therewith to operate the said door-operating mechanism, substantially as described.
2. In a dump-car, the combination of a supporting-frame, a drop-bottom portion thereof the car, a sliding bar contacting the under side of each swinging section, a fluid-pressure cylinder provided with a reciprocating piston connected with said sliding bar to operate the same and thereby each swinging section, substantially as described.
4:. In a dump-car, the combination of a supporting-frame, a drop-bottom therefor formed of a plurality of swinging sections pivotally secured thereto at each side of the longitudinal center of the car, a bar arranged to move backwardly and forwardly under each swinging section, a fluid-pressure cylinder provided with a reciprocating piston, and lever mechanism interposed between the said bar and piston-rod to operate the former, substantially as described.
5. In a dump-car, the combination of a supporting-frame, adrop-bottom therefor formed of a plurality of swinging sections pivotally secured thereto at each side of the longitudinal center of the car, a sliding bar arranged under each swinging section to operate the same, a fluid-pressure cylinder provided with a piston-rod, a bell crank lever connected with said piston-rod, and a link pivotallyconnected with the bell-crank lever and the said sliding bar, substantially as described.
6. In a dump-car, the combination of a supporting-frame, a drop-bottom therefor formed of a plurality of swinging sections, a track- Way on the under side of each swinging section, a sliding bar provided with antifrictionroll mechanism contactin the traclnvay of each swinging section, a iiiiid-pressure cylinder provided with a reciprocating piston-rod, a bell-crank lever connected with the pistonrod, and link mechanism pivotally connected with the bell-crank lever and the link mechanism, substantially as described.
