Title: Improvements in or relating to lubricating systems for machine parts
IPC: F16N7/40
Filed: 1945-07-18
Abstract: 618,948. Balancing turbine end thrust. GRIFFITH, A. A. July 18, 1945, No. 18471. [Class 110 (iii)] [Also in Group XXXIV] Leakage of oil supplied to the bearings of a rotor or rotors rotating on a fixed shaft through which the oil is supplied under pressure is prevented by applying air or gas pressure to the exterior of a sealing lip extending between the discharge from the moving bearings or rotor and a fixed collecting chamber whence the oil passes to an outlet passage in the fixed shaft. The air or gas pressure is also used to balance end thrust on the rotor. As shown, two independent rotors 10 are splined on hubs 11 fitted in their bore and at their sides with white-metal bearing-bush members 14, rotating round a fixed sleeve 15 on a fixed shaft 16, each rotor being clamped to its hub by end rings 12, 13 bolted together. Lubricating oil under pressure from a passage 21 in the fixed shaft 16 reaches the bearings 14 by a passage 22 in the fixed sleeve 15 and is distributed thereover by ducts 24 in the journal surface and side faces of the bearing-metal bush, the side faces co-operating with fixed discs 17, 18 to take up thrust ; these discs are pinned to the fixed sleeves 15 and to a fixed end member 19, as shown at 20. The discs 17, 18 have sealing lips 25 overhanging and engaging the peripheral edges of the bearing metal-bush 14 and formed with a circumferential channel 26 to provide a collecting chamber for the oil coming from the bearing. From the collecting chamber the oil passes by inward radial ducts 27 to an outlet passage 29 in the shaft. Air or gas under pressure is applied at the exterior of the sealing lip 25 to prevent escape of oil ; this air supply enters by a pipe 33 into a chamber defined by a fixed end member 32 and the clamping ring 12 of the rotor through the intermediary of co-operating sealing flanges 31, 30 formed respectively on the end member 32 and the clamping ring 12. The pressure air or gas passes through ducts 34 in the hubs to successive chambers similarly defined by the clamping rings 13, 12 and their co-operating sealing flanges 31, 30 ; by spacing these at different radial distances the end thrusts on the rotor can be balanced. In a ball-bearing modification, Fig. 4 (not shown), the collecting chamber is provided by slightly spacing the fixed discs axially from the hub which has a shoulder cooperating with a ring covering and extending axially beyond the periphery of the disc to provide the sealing lip ; the inward ducts in the fixed discs are cut across at their outer ends so as to be open to the chamber space. Specification 585,332 is referred to in the Provisional Specification.

Title: Improvements in or relating to front axles for vehicles such as tractors
IPC: B60B35/10
Filed: 1958-06-10
Abstract: 853,075. Motor vehicle axle structures; driving gear. SCHLEPPERWERK NORDHAUSEN VEB. June 10, 1958 [March 12, 1958], No. 18493/58. Classes 79(2) and 79(4). A tractor front axle 1 Figs. 1, 2 is adapted for conversion to driven or non-driven form by the attachment of alternative steering knuckles 11, 23 carrying driven or non-driven wheels 26. The knuckle 11 has a reduction gear assembly 12, 13 driving a toothed riin 14 in a hub housing 15 to which the wheel felloe 27 is secured, while the knuckle-23 has a non- driven hub 24 to which the felloe 27 is secured. The axle 1 is mounted on a centre pivot 2 and has clamps 3 at each end for the attachment of telescopic adjusting tubes 4 provided for track width adjustment. U-shaped holders 5 on the ends of the tubes 4 have the knuckle heads 6 bolted thereto and are arranged eccentrically so that when turned through 180 degrees the attachment holes for the knuckle heads 6 are raised or lowered to compensate for the different lengths of the knuckles 11, 23. Brackets 10 are provided on the underside of axle 1 for the attachment of the differential gear 9 which is coupled to the wheels through universal joints 16, 21, profiled sliding sleeves 17 and half shafts 22.

Title: Power strap tensioning tool
IPC: B65B13/02
Filed: 1959-06-01
Abstract: 873,582. Strainers. SIGNODE STEEL STRAPPING CO. June 1, 1959 [June 2, 1958], No. 18614/59. Class 45. A strap tensioning tool comprises a frame 22 having a foot portion 36 used for anchoring one end of the strap, a rotatable tensioning wheel 26 pivoted about the frame so as to swing to and away from the fixed anchoring member, a separator plate 102 mounted for rocking movement between the fixed member 36 and the wheel 26. The wheel 26, carried on the tensioning mechanism frame 24 pivoted by handle 30 about main frame 22, is non-rotatably mounted on a shaft 66 driven by an air motor 86 controlled by an air valve (not shown), operated by a button 90. The plate 102, has a pair of extensions 108, 110, Fig. 5, having guide pins 116 extending through apertures 114 therein, and fixed to the base portion 36, and is pivoted about blocks 118 mounted between it and the base. The plate is biased by springs 111, the lower ends of which bear upon the upper surfaces of extensions 108, 110 and the upper ends are adjustable by screws 113. In operation the tool is grasped by both handles 30, 34 ; movement of 30 rocks tensioning mechanism about pivot pin 44 to raise tensioning wheel, and movement of 34 towards 30 causes separator plate 102 to be pivoted on blocks 118. One end of the strapping is placed between the foot 36 and the plate 102 and the handle 34 released to anchor it, and the other end is placed between the wheel 26 and the chromium plate upper surface 122, the handle 30 being released so that the weight of the frame 24, wheel 26 and drive 28 causes the strapping to be gripped between the surfaces. During the tensioning operation with the wheel 26 driven in a counter-clockwise diredtion, the frame 24 is pulled clockwise about its pivot 44 thus increasing the pressure on the anchored strapping end. As pressure of wheel 26 increases, the plate 102 rooks on its longitudinal pivot 121, lifting extensions 108, 110 away from blocks 118, Fig. 8, thus increasing the area of contact between the wheel and strapping. The strap cutter mechanism 32 is mounted on the left of the plate 102, to which handle 34 is affixed and includes a cutter block, 142 cutter retainer 164, and cutter 172 having cutting edge which coacts with cutting edge 178 of the plate 102.

Abstract: 498,478. Sand-blast. HYDRO-BLAST CORPORATION. July 6, 1937, No. 18808. Convention date, Feb. 25: [Class 60] A sand-blast device in which a stream of wet abrasive is produced by the introduction of a supply of air and abrasive into a water stream comprises three axially aligned nozzles 9, 10 and 11 within a casing 1 with chambers 12 and 13 surrounding the discharge ends of the rear and middle nozzles respectively and means for introducing abrasive particles and air below atmospheric pressure into the liquid stream from the nozzle 11. Water under high pressure may be allowed to enter the nozzle 11 from an inlet 41 under the control of a valve 44 operated by a screw-threaded stem 45 passing through a sealing gland 46, 47, 48. The inlet to the air chamber 12 is controlled by a needle valve 38 so that the pressure within the chamber is below atmospheric. Air entrained by the water stream is in the form of bubbles of rarefied air. The chamber 13 is connected through a coupling 24 and pipe 71 with a sand feeder 55 comprising an axial tube 57 connected to the pipe 71, a surrounding tube 58 closed at the bottom and formed with lateral inlet openings 64 and an outer tube 57 with lateral inlets 64. The feeder is immersed in a tank 68 containing sand and water which is drawn into the tube 57 by suction created in the chamber 13. A connection 60 at the top of the feeder allows the apparatus to be flushed with water for cleaning. Spent abrasive flows through a grid 75 into the hopper 76 of a separator. Sand water and sludge mixture passes through a screen 77 into a passage 83. From here the water carrying the sludge flows into a sludge tank 78 and the sand passes into the tank 68. The larger particles pass through a trough 81 into a sludge tank 78.
