Title: Improvements in and relating to parachutes
IPC: B64D17/34
Filed: 1947-02-03
Abstract: 620,943. Paying-out apparatus. VENNING, R. B. H. Feb. 3, 1947, No. 3209. [Class 78 (v)] [Also in Group XXXIII] The opening of a parachute 1 is made gradual to reduce the shock, by connecting a control cord 3 attached to the centre of the canopy, to a device carried by the load which pays out the cord 3 in steps according to the aerodynamic load on the canopy. The device comprises a bracket, which has journalled on it a drum 4 on which the cord 3 is wound, and which carries a snail cam 5 and a roller 13. When the canopy is opened, the tension in the cord 3 exceeds a certain value and the drum is prevented from rotating by the roller 13 abutting against the arm 14 of a bell-crank lever 7 pivoted to the bracket at 8 and having its other arm 12 under the compression of a spring 10. When the tension in the cord 3 is reduced below the said pre-determined value on account of an initial deceleration of the load, the spring 10 is able to expand and rotate the end 14 of lever 7 below the roller 13, which is rotated slightly in the winding direction. The drum 4 is now freed to rotate clockwise and pay out a length of cable 3 to open further the canopy. After one revolution of the. drum 4, the lever 7 is brought back to its original position by a follower 6 secured thereto which bears against the inner surface of the snail cam 5. The canopy is thus opened in successive stages depending on the tension in the cord 3.

Abstract: 448,095. Prepayment mechanism for meters. ARON ELECTRICITY METER, Ltd., and RIORDAN, E. J., 80, Salusbury Road, Kilburn, London. Feb. 6, 1936, No. 3647, [Class 27] Mechanism for prepaying basic charges.-In a prepayment meter having a fixed-charge motor which acts in addition to the meter for returning the quantity mechanism to zero, the motor 1, Fig. 1, through gearing 2 drives a wheel 3 having a crank pin 4 which, by a connecting arm 5, rocks an arm 6 connected through gearing 8, 9 to an arm 11 which is thus oscillated through about 360 degrees, the arm 11 and pinion 9 being freely rotatable on a shaft 10. Another pinion 12 loose on the shaft 10 carries two arms 13, 14, the arm 13 extending into the path of movement of a bent end 11a on the arm 11 and the arm 14 being adapted to engage a stop 15 extending from a disc 16 which is adjustable by means of a pointer 17 co-operating with a scale 18. The pinion 12 meshes with a wheel 21 which is acted on by a spring 22 tending to keep the arm 13 pressed in an anticlockwise direction against the arm 11, the movement of which it follows until the arm 14 meets the stop 15. The amount of oscillation given to the arm 11 and so to the wheel 21 is adjusted by varying the position of the stop. The wheel 21 carries a pawl 25, Fig. 2, which engages and drives a ratchet wheel 24 during the forward (anticlockwise) movement of the wheel 21, the drive being transmitted through bevel gearing 28, 29, a worm 31 or 31a and worm-wheel 32, and pinions 34, 35 to one sun-wheel 37 of an epicyclic gearing. The radial arm carrying the planet pinion 41 is secured to a shaft 36 driven by the meter motor. The movements of the meter motor and the basic charge motor 1 are thus transmitted to the other sun-wheel 38 connected by a sleeve 39 to a wheel 40, from which the drives are transmitted to the prepayment quantity mechanism. The worms 31, 31a are slidably secured on a shaft 30 so that either may be geared to the worm-wheel 32 to alter the range within which the fixed charge is collected. The pitch of the helix of the worm 31 is four times that of worm 31a and corresponds to a range of two to eight shillings per week, while the range corresponding to worm 31a is from sixpence to two shillings.
