Abstract
471,055. Pneumatic single - stroke apparatus. MERZ, F. Feb. 3, 1936, No. 3255. (Class 8 (ii)] [Also in Group XXVI] A piston device 4 operated by pressure-fluid transmits motion to an external element by an arm 6 which passes through a longitudinal slit 3 in the cylinder controlled by a closing strip which in its normal position closes the slit over the whole cylinder length. The strip is lifted from the slit by the arm and returned to its seat only on the length comprised between the piston heads. In the construction shown in Fig. 2a, a flexible metal sheet cylinder is slit along a generatrix, and the arm 6 is bent to pass between the opposing flanges of the slit. The pressure in the cylinder and the resiliency of the material closes the gap on either side of the arm 6. In a modification, the flanges of the slit are radial, and the suction in the cylinder which operates the piston in this case helps to close the gap. In the construction shown in Fig. 4a, the cylinder has a slot of constant width and houses a thin cylinder 8 with a slot along a different generatrix. The arm 6 is shaped to pass through both cylinders. In the construction shown in Fig. 5a the slit is closed by a band which passes through the rod. In a modification of this construction, the resilient band is U-shaped. In a further modification, resilient split rings, housed in annular grooves in the cylinder, have ends which engage the band to hold it in place. The free ends of each ring press the band on its seat.
