Abstract

167,637. Herbert, Sir A., and Harrison, H. T. June 8, 1920. Rods, locking.-An interlocking-device for preventing appreciable simultaneous actuation of more than one of a pluralitv of control members A, A<2>, &c. comprises movable abutments such as balls, rollers, or sliding-blocks B, B<2>, &c., guided across the paths of the control members, and each normally lying, under resiliently applied locating- means such as the spring-pressed plungers D<2>, with its centre in the plane of contact of a pair of contiguous control members, all of which have bevelled faces A<8>, and are substantially of the same thickness as the abutments. When one control member, say A<4>, is operated, its bevels A<8> displace the abutments so that they wholly obstruct the remaining members. In the form shown, balls are contained in a tube C having an aperture C<2> of less width than the diameter of the balls, and through this aperture pass noses A‹ formed on the control members. The plungers D<2> are housed in enlargements C<3> of the tube C and carry rollers D, which, by engaging the shoulders C<4>, limit their inward travel. By extending the ball-carrying tube, the interlocking effect may be produced between members not contiguous.
