Tue

ariy s1" own is pwvided 31513 the antievc-r is pivotaliy 0011 the piston or the air-cy1-,

inder throws outward the lower end of the lever 32, swinging said lever on its pivotal connection with the link 36 as a fulcrum and thus simultaneously drawing inward on the link that connects the upper end of lever 32 with the lever- arm 24,1 and drawing oppositely on the link 36 that links said lever 32 with the lever 31, so that lever 31 and with it link 29 and lever 23 are drawn inward at the same time that link 30 and lever 24 are drawn inward. This actuation of the floating lever 32 by the piston rod 35, such lever 32 drawing simultaneously and oppositely upon the link and link 36, obviously equalizes the pulls simultaneously transmitted to the lever- arms 23 and 2% respectively, so that said lever-arms23 and 24: tend to be moved equally and simultaneously, in opening the doors, notwithstanding the fact that a variable strain may be imposed on the opposite rock-shafts 21 by the possible differences in the load resting upon the respective dump doors that are actuated from said res ectively opposite rock-shafts.

When the opper has been cleared, the air pressure in the air-cylinder is released, and the dump doors swing back into their closed position, coming to a stop at such closed position by reason of the contact of their mutually meeting edges along the longitudinal median line of the dump opening and also by reason of the engagement of their upwardly extended outer flanges 37' with the fixed downwardly extended flanges 38 on either side of the dump opening of the hopper. Such swinging back of the dump doors into closed position is induced by their tendency to gravitate from the upward position into which their opening movement shifts them, the pivot points of theirsupporting members being so positionedas to facilitate this downward movement into closed position, and the said closing movement is consummated by the coiled springs 89 secured to and coiled about the struts 40 that brace the depending brackets at either end of'the dump opening, the free ends of said coiled springs being respectively secured at 41 to the respective rock-arms that support the lower ends of the swinging arms upon which the dump doors are mountcd,-these springs being tensioned as the dump doors are forcibly opened, and such tension acting to impel the doors to closed position when the power holding the doors open is released.

It is obvious that the mechanism above described provides an entirely simple and positive method of motor control for the dump opening of a hopper car, and permits a s ngle car or a series or entire train of such cars to be dumped simultaneously by ,a single application of the power transmitted through the power or airline of such sefies or train.

My invention is herelnabove set forth as charge of said hopper andbodily movable laterally outward; upwardly extending rock arms supporting the said doors from below; operating connections for opening said doors; and a power-operated motor for actuating the said operating connections to open said doors'positively; substantially as specified.
