Abstract: 435,612. Rotary compressors ; centrifugal fans. NICHOLS, T. W., 63, Capel Road, Forest Gate, London. Feb. 6, 1935, No. 16804. Divided out of 433,459. [Classes 110 (i) and 110 (ii)] A cooling medium is circulated through the rotor, and may also pass over the outer casing, by means of a fan or impeller or pump. Air enters at k in the hollow shaft h, passes through the hollow rotor d and is sucked out of the part l of the shaft by the fan w, which is bolted between shaft-coupling members s, t. The fan may also have an extension v containing impeller vanes x, to cause a flow of air over the casing c. An outer covering e is secured to the casing c by projections f, which may also act as air baffles. Water may be used to cool the rotor and caused to flow by means of a centrifugal impeller on the outlet side of the hollow shaft. The above cooling means may be combined with the system described in Specification 433,459. If water jacketing is employed for cooling the casing, a single fan w is used for sucking the air through the rotor.

Title: Improvements in or relating to apparatus for handling glass or other ware
IPC: C03B35/12
Filed: 1927-06-28
Abstract: 274,068. British Hartford-Fairmont Syndicate, Ltd., (Assignees of Lorenz, E. H.). July 12, 1926, [Convention date.]. charging.-A device for transferring glassware to a leer comprises a transfer arm which can be swung about a horizontal axis to lift the ware from a receiving-position on to the leer belt, and means for moving the arm horizontally in order to distribute the ware on the belt. It comprises a frame 22 which is journaled in bearings 20, 21 on a fixed frame 19 so that it can be swung about a vertical axis. The frame 22 carries a pair of depending arms 23, and a shaft 25, journaled in the frame, carries cranks 27, 28 and a sprocket wheel 29. A chain 30. which has one end fastened to the rim of the sprocket 29, passes around this wheel and a second sprocket 31 and its other end is connected to the piston rod 32 of an air cylinder 34. Another chain 36, which has one end connected to the crank 27, passes around a sprocket 37 secured to an arm 38 that swings about a shaft 39 fixed to the depending arm 23. The other end of the chain 36 is secured to the piston rod 66 of an air cylinder 68, and a constant air pressure is maintained below the piston in the cylinder. Thus when air under pressure is admitted to the cylinder 34, the arm 38 is swung in one direction, and when the air pressure is released, the arm is swung backwards by the constant air pressure in the cylinder 68. Another arm similar to the arm 38 is similarly operated by the crank 28, but its operating chains are so arranged that the two arms swing simultaneously in opposite directions. The arm 38 carries tongs 40 which are closed by springs and. are opened by an air cylinder which forms part of the gripper head 41. The gripper head is pivoted on the end of the arm, and an endless chain 45, which passes a sprocket 46 on the fixed shaft 39 and another sprocket 44 which is fixed on the gripper head, keeps the head vertical whatever the position of the arm 38. The tongs are so operated that they close on a bottle X which has been brought up by a conveyer, and then release it when it has been lifted on to the leer belt 16. In order to distribute the bottles across the belt, the frame 22 is swung horizontally by a drum 83 secured to a shaft 84 and having a cam slot'which is engaged by an arm 86 secured. to the frame. The drum is rotated, through a ratchet wheel and a pawl 93, by the sprocket 31 over which the chain 30 passes. Thus each movement of the arms 38 moves the drum and so moves the frame 22 horizontally through a small angle. The two arms 38 may be arranged to remove bottles from one conveyer or from separate conveyers connected with different forming- machines.
