Title: Improvements in ticket punches.
Inventor: PAUL BARKER JOHN
IPC: G07B11/05
Filed: 1931-03-07
Abstract: 374,888. Ticket punches. BARKER, J. P., 24, St. Vincent Road, Wallasey, Cheshire. March 7, 1931, No. 7119. [Class 106 (iii).] A ticket punch particularly of the type described in Specification 152,390, [Class 106 (iii), Fares &c.], has fitted within the main casing a detachable single sectional part W machined or made in the form of a die-casting, according to the Provisional Specification, and carrying the counter Q, usually of the Veeda type, the star wheel R, hammer detent T, and bell S. The counter Q fits in guides w<1> formed on the arm w<2> and the star wheel R is rotatably mounted on a spindle r<1> separate from the counter and carried in a bearing w<3> integral with the section W. The inside face of the star wheel R has a polygonal recess with which engages a correspondingly shaped part q2 formed at the end of the spindle q<1> of the counter so that the counter bearings are relieved of transverse stresses. As the counter Q is slidably connected to the member W it can be removed and replaced by a duplicate counter without interfering with the separately journalled star wheel and aligning relationship to the other parts. The part W is provided with an arm w<4> which carries the bell S and is so shaped as to form a partition member w<5> which separates the punchings chamber a<1> from the mechanism. The face w<6> forms the inside guide for the actuating bar M thus ensuring alignment between the parts carried by the part W and the parts carried by the bar and main casing A. The punch P is hollow and contains a feeling device p<1> which, with the detent lever m<2> pivoted to the bar M and engaging with the abutment a4, prevents the working stroke of the bar M to be made unless a ticket is inserted in the slot F. The star wheel R is actuated by a spring-controlled pawl m<5> pivoted on the bar M, and punching without registering is prevented by a tooth of the partially rotated star wheel engaging a spring portion t<1> of the hammer detent T and moving it away from the bell S so that the end t<3> of the hammer T engages an abutment m7 on the bar M and prevents its return movement until on the complete actuation of the counter the part t<1> is released, the bell rung and the end t<3> drawn clear of the abutment m<7>. When the bar M is in the inoperative position the end t<3> of the hammer T is housed in a recess m<9> formed in the bar M thus preventing the hammer swinging and ringing the bell as a result of the movement of mechanism as a whole. The apparatus has incorporated with it an auxiliary punch in the thumb-piece G as described in Specification 374,868 and also sealed locking means to the punchings chamber a<1> and other interior parts as described in Specification 374,887.

Abstract: 548,405. Projectile fuzes. CLAESSON, M. A. June 13, 1941. No. 7510. Convention date, June 15, 1940. [Class 9 (i)] [Also in Group XL] In a gaseous discharge tube system for producing a current impulse with variable time delay for timing artillery projectiles increased constancy of the starting potential of the tube is obtained by passing a current of limited value through the tube immediately before the initiation of the time delay. The invention is described as applied to operating a fuze for igniting a priming composition in a projectile or the like. Fig. 3 shows an arrangement in which charged condensers C1, C2, are disconnected and switch S closed to initiate the time-delay which terminates when C2 is discharged sufficiently to operate the tube G. With the discharge resistance R connected as shown between the tube G and the fuze F, short-circuiting of either of condenser C1, C2 or of resistance R will not operate the fuze. Fig. 4 shows an arrangement in which timing is effected by charging condenser C2 from condenser C1. The fuze F instead of being arranged, as shown, in series with the discharge tube G may be in series with the condenser C2, Fig. 5, (not shown). Alternatively, condenser Cl may be replaced by a battery. The switches S may be acceleration switches closing at the end of the period of acceleration of the projectile or may be centrifugally operated.
