Title: Improvements in and relating to coin freed mechanisms for prepayment meters
IPC: G07F15/00
Filed: 1932-05-13
Abstract: 394,125. Prepayment mechanism for meters. BALDWIN, R., Dunloe, Temple Ewell, near Dover, and WILSON, O., 49A, Renmuir Street, Tooting, London. May 13, 1932, No. 13796. [Class 27.] Coin action, mechanical-connection and multiple-coin.-A prepayment meter coin mechanism is provided with a plurality of coin slots each of which is adjustable in size to take different denominations of coins so that any desired amount of money can be collected for each operation of the mechanism. The device is particularly intended for use with mechanism which enables fixed charges to be collected at definite intervals of time. In one construction having two coin slots 1, Figs. 1 and 3, the inserted coins rest on shutters 2 which form the bottoms of the slots and can be raised or lowered by adjusting screws 12 to vary the size of the slots. A button 3 on a rod 7 is pressed in and by collars 14 rocks levers 4 to move the coins sideways, the coins during this movement raising the ends of a locking spring 5, which is attached at its centre to the rod 7, out of notched catches 6 and allowing the rods 7 to be fully pushed in against the action of a returning spring 16. The rod 7 operates the meter mechanism, for example by a lever with attached pawl engaging a ratchet wheel in the meter mechanism. The slots 1 are formed by a pressed case 15 having apertures in its inner walls to allow the levers 4 to pass through, and guides 17 to keep the coins upright while being inserted. In a modified construction for use with more than two coins and as shown for use with four, the coins are inserted into slots in sliding blocks 18, Fig. 7, which are moved laterally to cause the upper edges of the coins to raise locking catches carried by the rod 7. The slots are adjustable as before bv shutters 2 on which the coins rest. The blocks slide on a rod 19 passing through them and are held in their initial position opposite the insertion slots by springs 24. On pushing in the button 3, levers actuated as in the previous construction move the inner blocks in or, as shown, rollers 28 carried by a pushing piece 27. The inner engage and move the outer blocks, the locking notches for the spring catches, that are carried by the rod 7, being formed on the tops of the blocks. In order to close one of the slots, the shutter 2 corresponding thereto is screwed up until a projection 30 thereon enters a recess 31 on the block, this adjustment being made after a coin has been inserted and the blocks moved sideways. The projection 30 then prevents the block from being returned to its initial position. In a further arrangement, a drum having radial slots of varying depth is located behind each insertion slot, the initial position of the drum being adjusted according to the size of slot required. The several drums are connected by gearing. Indicators.-Movement of each shutter causes an indication of the denomination of coin to be inserted to be shown through a window.

Title: Improvements in mechanism or apparatus for the support and display of rolls of sheetmaterial
IPC: A47F7/17
Filed: 1922-05-22
Abstract: 202,076. Wheelwright, B. May 22, 1922. Studio accessories. - Apparatus for storing and displaying rolls of sheet material, such as photographers' backgrounds, comprises a number of rollers 14, each of which carries a sheet of material and is supported by a disc 12 at each end of a shaft 11. At one end of each roller 14 is a sliding clutch 16, which is normally pressed into engagement with ratchet teeth 17 on one of the discs 12 to hold the rollers 14 against unwinding. The shaft 11 can be rotated by a cord 38 passing over a pulley 32 to bring any required roller 14 into the lowermost position for unwinding. The pulley 32 is notched for engagement by a positioning-plunger 34, and a pointer 36 indicates which roller is ready for operating. The mechanism for declutching and unwinding the lower roller is shown in Fig. 6, and comprises a rotatable shank 22a capable of sliding into and out of the framing 10. A hand or foot operated rod 28 acts through a forked pivoted lever 25 to slide the shank 22<a> against a depressible peg 19 connected to the clutch 16 by a pin 42, so releasing the clutch 16 against the action of a spring 23. A bevel-faced plate 22 on the shank 22<a> comes into contact with a similar plate 20 on the roller end, and, on rotating the shank by a cord 24 passing over a pulley part 21, the roller 14 is turned to wind or unwind its material. The rollers 14 are interchangeably held in slots in the discs 12, and are retained therein by turn-catches 15. The apparatus may be suspended from a ceiling or other bracket.

Title: Control device

Filed: 1972-03-29
Abstract: 1404341 Vehicle theft alarms UM ELECTRICAL DISTRIBUTORS Ltd 29 July 1972 14815/72 Heading G4N In a control system for activating electrical apparatus such as a relay RL1, a latch 6, 7 provides "armed" and "disarmed" conditions such that, in the armed condition, the apparatus RL1 is operable by either of two activating signals (e.g. from LP1 and LP2) whilst, in the disarmed condition the apparatus RL1 cannot be activated. The system includes a bi-stable device 2, 3 and a timer C1, VR1 arranged to change the state of latch 6, 7 by specified combinations of activating signals being present or absent during a predetermined time period. Vehicle theft alarms.-A system is described in which the horn of the vehicle is sounded and the ignition immobilized if a door of the vehicle is opened when the system is armed. If a door, boot or bonnet of the vehicle is opened, a switch SW2 is closed, lighting lamp LP1 which irradiates photo-transistor LST1 which initiates a chain of gates 1, 2, 6, 5, 8 so as to turn on transistor T3 which energizes relay RL1. The relay is held energized by contacts SW6 for two minutes while capacitor C4 discharges via transistors T4, T5. Contacts SW4 of relay RL1 break the ignition circuit, contacts SW8 energize a flasher 30 which feed intermittent current to the horn via contacts SW8. A similar action occurs if the ignition switch SW3 is closed, since this lights lamp LP2 which irradiates photo-transistor LST2. Disarming.-The system is disarmed by momentarily changing over a key-operated switch SW1, this action charging C1 and discharging C2. A latch, formed by NAND gates 6 and 7 is reversed so that gate 6 gives a 0 which is passed by gates 5 and 8 to turn off T3. C1 begins to discharge via VR1 until latch 6, 7 changes over causing C2 to charge, thus rearming the system. If, however, a door is opened before C1 has discharged, SW2 closes and gates 1 ... 4 provide Is so that C1 is recharged via D1. Gate 5 does not change since C2 is still discharged. When the door is reclosed SW2 opens and C1 begins to discharge via VR1. If the ignition switch SW3 is closed before C1 has discharged (e.g. within 20 sees) gates 2 and 3 are reversed, C1 is recharged and this condition maintained until a door is opened. Re-arming.-When the ignition switch SW3 is opened, gate 4 gives a 1 and gate 3 remains on so that C1 remains charged via D2. When a door is opened, SW2 is closed so that gates 2 and 3 are reversed. On reclosing the door, gates 1 and 4 provide Os. C1 discharges until the latch formed by gates 6 and 7 reverse, thus re-arming the system. Bridge B 1 prevents a reverse voltage being supplied. Modifacationa.-SW6 may be manually set to its second position to provide a hijack alarm. SW4 may operate a valve in a compression ignition engine. It is mentioned that the device may be used for the protection of buildings or safes.
