Filed: 1973-07-20
Abstract: 1442315 Tongs for suspending glass TRIPLEX SAFETY GLASS CO Ltd 11 July 1974 [20 July 1973] 34702/73 Heading C1M Tongs for suspending glass sheets comprises an elongated suspension member, a pair of tong arms pivoted about a pivot mounted on the suspension member which tong arms extend beyond the pivot to form jaws, a tong link attached to one end of each arm the other end of each link being connected to a biasing member which in its rest position acts to close the jaws. The biasing member is preferably a weighted slider slidable about the suspension member. In one embodiment (Fig. 1) the suspension member 2 is attached to a tong bar 4. A rocking frame 47 one end of which contacts a tong actuating member 60 pivots about a pin 51 mounted on the suspension member 2. Adjacent its other end the rooking frame has a pivot 46 which passes through straps 43 which are in turn connected to the slider 28 and its weight 37. Thus downward movement of the member 60 causes the slider to rise. Since tong links 24, 31 are pivoted about pivot 26 on the slider 28 the tong arms move outwards about link 8. In a second embodiment (Figs. 6. 7) the suspension member is supported by a tong gate comprising upper and lower supporting members pivoted about a rod 71, the rod 71 being attached to the tong bar 70. In this embodiment upward movement of the slider 120 is produced by movement of a cable 126. The other end of the cable is connected to a bell crank lever 159 one arm of which is acted on by a pusher rod 157. Fig. 10 illustrates the cable 140 which supports the tong bar 70 and by which: it may be raised and lowered. The tong bar usually cranes six pairs of tongs.

Abstract: 981,040. Centrifugal pumps. THOMPSON RAMO WOOLDRIDGE Inc. Sept. 3, 1963, No. 34822/63. Heading F1C. In a pump comprising a housing formed with a volute pumping chamber 37 having an axially extending inner wall 38 merging with an inner portion 39, 40 of the housing, which portion extends axially and radially inwardly of the pump and an impeller having a vaned wall 12 and journalled in a bearing 61, 62 mounted in the inner portion of the housing, the vaned wall 12 co-operates with the inner portion of the housing to form an orifice 83 which communicates with the volute pumping chamber to allow leakage therefrom to the bearing for lubricating thereof, and one or more openings 84 through the inner portion of the housing allow leakage from between the vaned wall and the inner portion. The leakage through the orifice 83 also acts as a coolant for the bearing and the openings 84 prevent pressure build-up behind the impeller. The pump is driven by an hydraulic motor 42 and may function as high-speed low-pressure fuel pump of high output or a booster pump and vapour separator, the vapour escaping through holes 94 which are substantially tangential to the impeller casing 21. The leakage passage following the orifice 83 may extend only radially or it may extend initially radially and then turn through a right angle and continue parallel to the rotational axis. The bearing consists of two ball bearings 61 and 62 which are pre-loaded by a spring 63. Vent openings 90 in the impeller hub 11 allow dirt to be drained from the area of the bearing back to the pump inlet. Three bosses 23 for mounting the pump also provide attachment means for the fasteners 26 of an inlet screen 27.

Abstract: 888,693. Mechanical garages. O'SULLIVAN, E. Feb. 14, 1958 [Nov. 14, 1956], No. 34861/56. Class 78 (4). A frame sufficiently strong to support a whole column of vehicle-carrying cages surrounds each cage of a vertically-circulating system in a mechanical garage, the frames being substantially in the lateral centre-planes of the cages. As shown, the load-carrying frame comprises members 45, 48, 51 (Fig. 3), and when a number of cages are arranged in vertical columns 11, 12 (Fig. 1), the members 48, 51 of adjacent cages are in contact. The columns of cages are raised and lowered by hydraulic rams 14 which engage the lowest members 51, and the top and bottom cages are transferred from one column to the other by trolleys 15, 16, which may be electrically operated. The cages may be circulated from the position shown by first raising column 11 until the top cage engages a device on the trolley 15 to cause depending claws 60 to engage under its tubular members 47, Fig. 3. The column is then slightly lowered so that the top cage is clear of the rest, which are supported on pivoted ratchet frames 70a, 70b (Fig. 5), which ride over the cages during their upward travel, but are urged to engage beneath the cages by springs 89. The frames can be disengaged to allow a column to be lowered by first raising the column clear of the frame and then energizing a solenoid 88. The initial raising movement also disengages the claws 60 of trolley 15 and allows a complete column to be lowered until the next to bottom cage engages the ratchet frame 70a, or 70b (the solenoid having been de-energized), the lowest cage then descending slightly on to the trolley 16. In this way the cages can be circulated in either direction, and the movements are preferably automatically controlled so that the pressing of a button causes a selected cage to be brought to the bottom of column 11 by the shortest route. The cars may be driven into and out of the cages, but are preferably loaded by a trolley 35 which pushes a wheeled platform 31, carrying the car, into the cage. A platform 31 is provided for each cage. Such loading apparatus is described in Specification 863,025. According to the Provisional Specification the ratchet frames 70a, 70b may engage the cages through rollers, and each cage may be independently supported. Specification 693,170 also is referred to.
