Title: Improvements in or relating to prepayment meters
IPC: G07F9/06
Filed: 1931-02-11
Abstract: 372,818. Prepayment mechanism for meters. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Feb. 11, 1931, No. 4332. Convention date, Feb. 12, 1930. [Class 27.] Prepaying basic charges.-In a prepayment meter having a basic fee collecting device which is moved by a, member projecting into the path of the coin till and in order to prevent dust and damp from entering, this member is situated outside the casing which surrounds the fee collecting mechanism and its spindle passes through the wall of the casing. After insertion of a coin 15 in a slot 14 and turning a knob 16, the planet wheel 3 of the usual epicyclic quantity mechanism is set forward by the rotation of a sun wheel 1, the wheel 3 being returned by the meter 4 which rotates the other sun wheel 2. The wheel 3 operates the switch tripping gear and carries a pointer 5 moving over a scale 6. The sun wheel 1 is rotated through a wheel 7, Maltese gear 11, and wheels 12, 13, and the wheel 7 drives a wheel 8 normally locked by a pin 10 on a lever 9 which is released momentarily at each coin insertion by a pin 120 on the wheel 12 acting against a nose 90 on the lever. The wheel 8 drives, through a friction clutch 82 and against the action of a spring 81, a shaft carrying a control member 84 which moves from a movable stop 842 carried by a rotatable scale wheel to a fixed stop 840. When the control member 84 reaches the stop 840, a projection 843 thereon releases a latch 174 from a member 175 on the spindle of a bolt 17 which is held in a lock 172 of the coin till 171. When an official releases the lock 172 and withdraws the till, the bolt 17 moves in the direction of the arrow 173 and removes a pin 170 from an arm on a shaft controlled by a spring 800 and having a finger 80 which releases the pin 10 from the wheel 8. The spring 81 through the clutch 82 rotates the wheel 8 in the reverse direction to rotate the sun wheel 1 backwards and cause the pointer 5 to move towards zero. The amount of the reverse rotation of the wheel 1 is determined by the position of the stop 842. The spindle of the bolt 17 passes through a packed opening 177 in a casing 176 enclosing the basic fee collecting mechanism. The basic fee is paid when the member 84 again reaches the stop 840. If it has not been fully paid during the payment period, the projection 843 will not release the latch 174. The official then, by inserting a key through a sealed opening in the casing into a slit 88, rotates the scale wheel by means of mechanism 86, 87. This causes the stop 842 to move the member 84 to release the latch 174. In such a case, the official can adjust the further basic amount to be paid. Specification 372,817 is referred to.

Abstract: 118,237. Usines G. Derihon, Soc. Anon., and Derihon, E. March 13, 1918. Regulating.-Relates to engines in which carburetted air is supplied at constant pressure at any altitude or under different atmospheric conditions, the air being compressed into a reservoir fitted with a relief valve, as described in Specification 116,644. An outlet 4, 6 from the reservoir to the atmosphere is controlled by a piston valve 7 having one end 9 subject to atmospheric pressure and the other end 8 to a vacuum, created by connecting the space 18 to a vacuum pump or to the induction pipe or inlet conduit of the engine. The piston 7 is controlled by an adjustable spring 15, and has a port 16 constantly open to the passage 4 and a port 17 which opens to an outlet 6 to an extent dependent on the variations in atmospheric pressure acting on the end 9 of the piston. The spring 15 may be adjusted bv means of a sliding collar 14 connected by a rod 24 to a bell-crank lever 23.

Title: Improvements in or relating to belt-fastening machines
Inventor: NEALE LESLIE ARTHUR
IPC: F16G3/00

Abstract: 943,984. Belt fastening machines. HAYDENNILOS Ltd. Jan. 30, 1962 [Feb. 8, 1961], No. 4625/61. Heading F2Q. U-shaped plate fasteners 1, Fig. 14, as described in Specification 943,983 are held in a comb bar 34 and clinched on to a belt end 4 in three stages by a jaw unit 42 movable along a rack bar 40, the jaw unit comprising an upper cheek 56 carried by a lever 55 pivoted on a transverse bar 39, and a lower longitudinally-slidable block 26. The block 26 is attached to a bar 60 having a slot 59 engaged by a pin 57 on a sliding nut 50 linked to the jaw lever 55. On initial rotation of the arms 52 on the operating screw 51 (first stage) the cheek 56 closes the fastener 1 on to the belt 4, the points of the staple 7 entering the recesses 25, Fig. 11, in the block 26. As rotation of arms 52 is continued (second stage) the pin 57 engages the end of slot 59 and moves bar 60 and block 26 to the right, thereby bending over the protruding staple points (Fig. 12, not shown). The arms 52 are then operated to open the jaw lever and the unit 42 moves on to the next position. The cheek 56 is wide enough to span two fasteners in the comb so that the firststage pressing of the next fastener also involves re-pressing of the previous fastener (third stage) against a fixed block 28, Fig. 13, alongside the block 26. At each position a stop 63 on the jaw unit engages an unpressed fastener to locate the unit. The belt is clamped by a spring- actuated bar 31 against a transverse bar 30. The transverse bars 30, 34, 39, 40 extend between side plates, Fig. 17 (not shown), which also carry a support bar 41. According to the Provisional Specification the machine may be hydraulically operated.

The drive unit also carries a second roller 22 which is pressed against the opposite side of the guide rail 3 by a spring in a tubular member 19. Preferably the vertical axis of pivot 12 is in the vertical longitudinal median plane of the guide rail 3. The track may have crossing points at which a guide rail segment 27 may be rotated about vertical axis 26 to divert the carrier thereon from rail A to rail B, the orientation of the load carrier 6 remaining fixed when the rail segment 27 and drive unit, i.e. motor, rollers, etc. are rotated. Instead of two rollers 17 and 22 rotating about vertical stub shafts 16 and 20 as shown, a single flanged roller (28), Fig. 5 (not shown), rotating about a horizontal shaft may be employed, and pressed against the top of the guide rail 3 by the weight of the carrier and/or the action of a spring (29). Alternatively, Fig. 6, the carrier may be suspended from overhead rails 31 and 32 and driven by a roller 36 co-operating with a central guide rail 30.
