Abstract
170,508. BaHer, W. S. Graff-. Nov. 25, 1920. Footboards. -- A fluidpressure actuated device for operating footboards, and for other purposes comprises a toothed segment K<1> mounted on a cylinder C which acts as a piston in respect of the cylinder A, the segment engaging a stationary rack E so that in operation it rolls along the rack and thereby increases the throw of the arm K connected to a door or other member. The front end of the cylinder C has its open end closed by a stationary piston D secured to a rack E, which is bolted to the be'd plate B. In operation, pressure-fluid is admitted through a pipe L to the space in the cylinder side of the member D, the valve X being opened to exhaust. The cylinder is moved so as to telescope into the cylinder A and the segment K is rolled along the rack and moved into the position shown in dotted lines. This movement is reversed by opening the valve X to fluid pressure. In the arrangement shown in Fig. 4, the rack is mounted on the bed plate at the side of the cylinder C, and the member D is secured to a hollow rod N attached at the other end to a fixed block O. This block is provided with a pressure inlet P and a bye-pass O<1> with a ball valve O<2>. The end of the cylinder A is provided with a similar arrangement. The piston end of the cylinder C carries a choking rod R, the ends of which engage with the tubes P towards the end of the operation of the cylinder C, so as to cushion its movement. The rod R may project at one side only of the piston D.
