    • 598,520. Wicket gates. DENNISON, KETT, & CO., Ltd., and MOSS, D. J. Nov. 7, 1945, No. 29733. [Class 20(iii)] [Also in Group XXV] In a wicket gate 10 for rolling shutters &c. which is hinged at 16 to a fixed support and has a fixed flange, or stop 12 on one face and a hinged movable stop 18 on the other, which engage opposite sides of the shutter 14 when the door is closed, a handle-operated slide member 22 is mounted in guides on the door and connected to the stop 18 by an articulated linkage including a link arm 27, whereby the thrust of the slide member is transmitted to the stop 18 in a direction transverse to the plane of the shutter. In the form shown, two slide members and corresponding linkage are provided connected to two hinged stops and the guides comprise a bracket 25, and slots 23 in a casing 24, both secured to a metal plate 20 extending the width of the door. The slide members have cranked ends and are moved horizontally by pins 35 acting in vertical slots therein, these pins being fixed to a plate 34 rotated with the door handle 33. In an alternative form, rollers at the ends of a handle-rotated arm engage in slots in slide blocks connected to straight slide members. Each of these members is pivoted to one corner of a triangular rocker plate pivoted at its other free corner to a link arm acting directly on a hinged stop. In both cases the parts of the linkage may be so disposed, (as shown), as to render it irreversible to prevent the stops being prised open from the outside. A keyoperated lock may be provided operating on one of the slide members.

[Classes 80 (ii) and 80 (iii)] A winding or crank handle for operating a roller shutter and which is loosely mounted upon the shaft to be operated so as to allow rotation of the shaft without corresponding movement of the handle, and arranged so that a limited angu. lar movement of the handle causes a driving connection to be set up between it and the shaft without axial movement of handle relative to shaft, has a driving connection of a positive character constituted by the direct interengagement of an integral part of said handle with a part of the shaft. A coupling member 12 is mounted on the shaft 14, axial movement being prevented by a screw 16 entering a groove 17, and also by a cover plate 18 secured to the end of member 12. This member carries a pin 13 upon which is mounted the crank arm 10 provided at its bifurcated end with nose-like portions such as 21 for engagement with recesses 22 in the shaft. Normally the crank arm hangs vertically with the noselike portions out of engagement, but, upon limited movement of the arm, about the pin 13, these portions engage the recesses and a positive drive results. The handle grip 23 is pivoted to the crank arm at 24 and may be folded into the dotted position to obtain a flat non-obstructive formation. The handle may be locked in its working position by a plunger 26 releasable by rotating a cam 28 by a knob 29. The nose-like parts may be on the shaft and the recesses in the crank arm.

[Class 47 (ii)] Relates to roller shutters wherein the operation of a thermal element releases a spring drum which, by its rapid rotation, initiates the automatic closing of the shutter, and consists in arranging that the drum is operatively connected with the shutter only as a result of the rotation of the drum. As shown, the shutter 1 is mounted on a roller 2 rotatable on a spindle 3 under control of a counterbalancing spring 4. Mounted for rotation on an extension of the spindle 3 are a spring drum 7 and a disc 14, the latter carrying a pivot pin 20 to which are fixed a pawl 15 and an arm 22. The pawl co-operates with a ratchet wheel 13 on the roller 2, being held normally from engagement therewith by a spring, and the arm 22 is adapted to be engaged by one of a series of lugs 23 on the drum 7. The drum is held, with its spring wound up, by a cable 10 with a fusible link 12. When the link fails, the drum is rotated by its spring, a lug 23 engages the arm 22 to rock the pawl 15 into engagement with the ratchet wheel, and the roller 2 is driven to uncoil the shutter. In order to prevent operation of the spring drum when the shutter is already lowered, engagement of an arm 24 with the outer surface of the rolled shutter or of the roller is adapted so to control an arm 27 that the latter lies in the path of the lugs 23, so as to prevent rotation of the drum 7, when the shutter is lowered. The pawl 15 might be carried by the drum 7 and controlled by a cam. A suitable lever may be included in the cable 10 to reduce the tension exerted on the link 12 by the spring drum. In a modification, applied to a double shutter with a manual winding gear, a pawl is brought, by centrifugal force upon rotation of the spring drum, into engagement with internal teeth of a gear-wheel in mesh with a pinion on the main winding shaft of the winding mechanism.

[Class 47 (ii).] Means for initiating the closure of a rolling shutter in case of fire comprises a gapped rotary driving member which normally is held inoperative by a fusible link and is arranged, when released, to be driven by a spring and engage a rotary member associated with the shutter. The double shutters 1 are wound on drums 2 and normally are operated by a manual winding gear comprising a hand wheel 16, shaft 12, and bevel gears 11, 10, 8, 7. The automatic closing gear comprises a pinion 18 fast on the shaft 12 and a driving drum. The latter comprises a gear wheel 19, Fig. 5, which is rotatably mounted on a shaft 27 and has some of its teeth removed to leave a gap 20. Normally, the drum is held, with its gap 20 opposite the pinion 18 and its driving spring 24 wound up, by a cable 30 embodying a fusible link. When the link melts, the drum is rotated by the spring 24 so that the gear wheel 19 drives the pinion 18 in a direction to lower the shutters. The drum is arrested by stops 28, 29 after one revolution, the lowering of the shutters continuing under gravity. In a modification, the automatic closing gear is applied to a double self-coiling shutter. The gear wheels described may be replaced by friction wheels or spur wheels.

[Class 47 (ii).] Relates to roller shutters of the type which, upon the outbreak of fire, are automatically released for unrolling by the operation of a fusible link or other heat-responsive device. According to the invention, the shutter 2, Figs. 1 and 2, is weighted at its lower end or extends under a releasable weight 13, and the fusible link 28 is included in a system directly supporting the shutter or weight. The weight 13, in the construction shown, extends across the complete width of the shutter and is provided at its ends with rollers 14 to prevent it from wedging in the guides 12. It is supported at each end by the lower limb of a pivoted arm 19, the upper limb of which is connected to the fusible link by a wire rope 23 which is adjustable in length. The centre of the rope passes through a ring 29 of the link and the latter is adjustably connected by a screw 31 and nut 34 to a fascia plate 27. When the link fuses, the arms 19 are freed and are rotated by springs 22 to release the weight. The latter, in falling, strikes the brackets 18 secured to the lower edge of the shutter and thereby effects the descent of the latter. The lower edge of the shutter is formed by two angle-bars 3, 4, the ends of bar 3 being guided in steel guides 7 which are covered on either side by strips 9, 10 of hard wood. The guides for the weight 13 may be lined with asbestos.

J., and TURT, H. L., 126, Whitechapel High Street, all in London. Oct. 17, .1929, No. 31575. [Class 27.] Testing coins; coin action, thrust.-In a coinfreed vending machine, the diameter, thickness, and milling of a coin are tested by a number of apertured plates, the apertures of which are brought into registration with one another, when the tests are satisfactory, and permit such movement of a plunger as to bring about the release of latch mechanism controlling access to the goods to be sold. A coin 36, Fig. 6, inserted through a slot 35 raises, against the action of a spring, a hooked plate 37 which is suspended by a pair of links 38 pivoted at 41 to the framework. The plate 37 engages the coin at two points 46, 47, the coin being supported by a pivoted blade 55 which has a knifeedge 56 to engage the milling and is controlled by a coiled spring 58. If the coin is smooth or worn. the blade 55 slips on its periphery and returns to the front of the machine and the coin being unsupported drops down. The diameter is tested by the three-point contact 46, 47, 56 so that, if the coin is of correct diameter, the plate 37 is moved to such a position that an aperture 64, Fig. 7, in a plate 48 carried by it, is in alignment with a plunger 81. The thickness is tested by a pair of levers 69, 70, which are moved apart by the coin and actuate a pair of interconnected levers 73, 74, the lever 74 having an aperture 79 which is brought into registration with the aperture 64, if the coin is correct. An arm 60 provided with an elbow 61 is carried by the spindle of the blade 55, and engages an apertured plate 59 to bring the aperture 65 therein into registration with the apertures 64, 79, when the coin is correctly milled. The plunger 81 is pivoted at 88 to a rocking lever 83, which is pivoted at its middle to a hand-operated spring- controlled plunger 85, and has a hooked lower end 86 engaging the elbow 61. When the plunger 85 is pushed in, the lever 83 rocks about the elbow 61 as a fulcrum, and the plunger 81 moves through the apertures 64, 79, 65. If however, owing to a coin being incorrect, the plunger 81 is blocked by any of the plates 48, 74, or 59, the lever 83 rocks about the pivot 88 and its hooked end 86 forces back the blade 55 to its initial position thereby allowing the coin to drop through a shoot 89, Fig. 12, to be returned to the operator. When the coin is correct, continued movement of the plunger 81 actuates latch-releasing mechanism and a lever 93, which, through a pin and slot connection, moves a coin receptacle 96, Fig. 12, to bring the mouth 97 of this under the coin 36. The blade 55 is carried by the receptacle and moves from under the coin, which is forced by the plate 37 into the passage 97. The levers 69, 70 are carried down by the plate 37 and are opened to release the coin by engaging cam surfaces. Articles stored in separate compartments.-Packets of cigarettes 15, Fig. 1, are stored in compartments 12 of a flat shallow casing 11 and are delivered face first. Each compartment has a false back 16 pressed forward by springs 18, when a door 13 is opened, to push out the packet 15 therein, the movement of the back being limited by guide pins 17, which are arranged so that the movement of the packet, at the side adjacent the door hinge 19, is greater than at the other side. The door is opened by a spring, when a latch 14 having a bevelled nose 32 engaging an eye 33 on the door is released, and is closed by spring-pressed plungers 21 acting on extensions 23 of the door, when the packet is removed. The packet normally holds the plungers out of action by engaging a false side 31 which is connected to the plungers by bell-crank levers 26, 27. The latch 14 is released by a lug 103 thereon coacting with a shoulder 102 on the controlling plunger 81. The latch 14 may be released by a key, when it is desired to fill a compartment, the coin receptacle being moved at the same time to allow a coin to fall out of the machine for collection.
