Title: Improvements in conveyor systems for tyres and other articles
Inventor: NICHOLS HAROLD BLAKEMORE
IPC: B65G17/06
Filed: 1952-06-28
Abstract: 729,655. Endless conveyers. DUNLOP RUBBER CO., Ltd. May 26, 1953 [June 28, 1952], No. 16335/52. Class 78 (1). Apparatus for transporting articles and automatically depositing them at predetermined discharge points comprises an endless conveyer having a plurality of article-supporting portions separated by gaps through which an article can fall, means for continuously driving the conveyer, a movable discharge device above the conveyer immediately following each discharge point, and means for moving the said devices away from or towards the conveyer so as either to allow an article to pass the device or to cause the device to contact said article so that forward movement of the article on the conveyer is arrested and the article is thereby discharged through the adjacent gap in the conveyer. Uncured tyres are fed to moulding presses 2 by an endless conveyer 1 consisting of a pair of endless chains 4 linked by slats 5 arranged in sets with gaps 6 between each set, the length of the gap being greater than the diameter of the tyres. Adjacent each pair of presses is a vertically movable gate 11 which can be raised to allow a tyre to pass beneath it or lowered until it is just above the slats so as to arrest a tyre and allow the slats to pass underneath until a gap 6 is reached when the tyre will fall on to a roller conveyer 8. Each gate is normally held in its upper position by a counterpoise 14 on a rope 12 connected to the gate, whilst it is lowered to effect discharge of a tyre by a solenoid 15 which overcomes the counterpoise. This solenoid is operated by " on " and off " switches 16, 17 which are located just below the upper flight of the conveyer 1 and actuated by any one of seven trip levers 18 pivotally mounted on the leading slat 5a of each set of slats and which can be tripped by an operator at the feeding point 3 so as to extend below the slats in the path of the switches 16, 17. The pairs of switches 16, 17 for each gate 11 are offset laterally relative to the switches for the other gates so that the operation of any particular gate can be effected. The trip levers are automatically re-set by gravity as each slat 5a completes its circuit. A cured tyre is fed to a conveyer belt 7 by a roller conveyer 10.

Title: Gas flow control mechanism
Inventor: KNIEBES DUANE VAN
Filed: 1965-04-15
Abstract: 1,60,538. Fluid-pressure servomotor systems. INSTITUTE OF GAS TECHNOLOGY. April 15, 1965, No.16378/65. Heading G3P. A control system for gas lights utilizes a solar cell to control the supply of gas to the light. In Fig.2 (not shown), gas flows to the lights via a pressure regulator 11, line 10, main valve 12 and line 16. The main valve comprises closure members 52, 54 connected to a diaphragm 36, the diaphragm being urged to close the main valve by pressure of the gas being controlled and urged to open this valve by a spring 62. A by-pass line 18 containing a restriction 24 communicates with the chamber 46 above the diaphragm and with a line 20 supplying gas to a housing 70 from which a pilot gas supply is taken via line 26. The line 20 terminates as a nozzle 72 the effective area of which is varied by a valve member 88 mounted on a lever 86 rotatable with the armature 78 of a galvanometer 74. The galvanometer is connected to a solar cell 23 having a protective shield 96. The arrangement is such that when the solar cell is not energized, i.e. at night, the valve member 88 closes the nozzle 72, except for a bleed to the pilot, and pressure builds up in chamber 46 to open the valve. When the cell is energized the valve member 88 moves away from the nozzle and reduces pressure in chamber 46 to allow the pressure of gas in chamber 44 to close the valve. A capacitor may be connected across leads 92, 94 connecting the solar cell to the galvanometer to cause the gas light to 'blink'.

Title: Improvements in and relating to Machines for Erecting Walls of Bricks and the like.
Inventor: KAYE STEWART
IPC: E04G21/22
Filed: 1917-11-13
Abstract: 119,331. Kaye, S. Nov. 13, 1917. Brick-laying machines.-A brick-laying machine comprises a vehicle 1 mounted on rails, a turntable 3, a telescopic pillar 4 operated hydraulically, a horizontal extensible frame 32, a travelling carriage 40, and conveyer chains for feeding and laying the bricks. The turntable 3 is rotated as required by a, motor 5 and worm gearing. The bricks are placed in compartments in a receptacle 6 which can be turned intermittingly by a stop 25 on a chain 21 to bring the compartments successively over a ram 11 operated from the motor 5. The bricks 15 are then released by a bottom plate being automatically swung open by a stop, and are fed forward one by one by the reciprocating ram. When all the compartments are empty, the receptacle 6 is replaced by a full receptacle. The bricks are thus fed to a conveyer chain 30, the slack of which is taken up by a weighted wheel 34. The chain consists of double links and pivoted or hinged plates 37 which remain horizontal and carry the bricks up and along the frame 32. whence they are transferred by spring arms 48 and a drop plate 49 to the laying-chains 45. These chains pass over rollers 46 which are carried by a frame swivelling in a pivoted ring 41 so that the chains can be retained in the same vertical plane as the frame 32 is swung round and extended. The spindle of the rollers 46 carries a star wheel 52 actuating a trip lever 53 which in turn operates the drop plate 49. As the plate drops, the spring arms 48 are separated by the cone 55 and bricks 57, 58 are gripped between the arms 48 and flanges 50 of the plate 49 and are thus removed downwards from the pivoted plates 37 and lowered to gripping-plates 59 on the laying-chains; a cone 60 causes the arms 48 to open and release the bricks, and a spring 61 restores the plate 49 to its upper position. To compensate for the variation in the angle between the vertical planes of the chains 45, 30, the bricks are turned, as they are transferred, by giving a partial rotation to the plate 49 by means of a collar 66 carried by a yoke 67 and sliding on a spiral web 65 of a rod 64 fixed to the distance piece 63. The collar normally slides on the rod 64, and the yoke 67 and plate 49 merely drop; if the chains are angularly disposed, the piece 63 brings i the spiral web 65 into action, and the collar 66 is turned in its descent. The lower ends of the chains 45 pass under wheels 47 having plungers 68, the tapered ends of which engage pins 71 to displace the plungers and eject the bricks. The mortar is led by fiexible pipes from a tank 73 to a vessel 74, whence it passes through pipes 75, 76 to form layers on the bricks already laid. The laying-apparatus is guided by telescopic rods engaging the wall.

An automatic dish-washing machine is characterized by an extensible rotatable member pivotally mounted in the tub and adapted for receiving washing liquid, and which is in a lowered position when not receiving liquid and in a raised position in response to liquid pressure. The upper end of the extensible member has flow restricting means to direct the flow of liquid into a thin sheet which revolves within the tub as the member rotates. A dishwashing machine has dish racks 23 and 24, Fig. 1, and rotatable spray arms 32 and 37 at lower and upper levels of the tub 9. Washing at an intermediate level is carried out by the rotatable spray tube 66 which is so telescopically mounted in housing 39 that when liquid is applied to the spray structure, the spray tube functions as a piston and is raised uncovering orifices 70 and 71, Fig. 4 from which are discharged sprays B. In addition the upper end of the tube has a flow restricting means with an off-centre baffle (not shown) to provide a double orifice resulting in sprays C and D. When the liquid flow ceases, spray tube 66 falls under gravity to a full retracted position and thus affords no obstacle to the loading of dish rack 24.
