Title: Improvements relating to lubrication systems of gas turbine engines
IPC: F01D25/18
Filed: 1944-06-08
Abstract: 610,010. Lubricating toothed gearing. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and POWELL, J. A. BENNETT-. June 8, 1944, No. 11030. [Class 80 (i)] [Also in Group XXVI] In a lubrication system for supplying lubricant to a plurality of localities disposed along the shafting of a gas turbine engine comprising internal substantially axial ducting through the shafting communicating towards one end with a delivery point for lubricant at atmospheric pressure, the bore of the ducting has change of radius with respect to the axis of rotation of the shafting so as to impel the lubricant through the shafting and the lubricant is led from the supply source to the delivery point over a path disposed externally of the shafting. The lubricant is injected from a fixed pipe 97, Fig. 2, into the bore of the shaft 63, an increase in the diameter of which at 8 causes the oil to be pressurized by centrifugal action and flow rearwardly. Passage 39 and chambers 41 and 42 pass oil from the bore to the clutch mechanism 43 and passages 44 pass oil to the bearing 46. The high - speed pinion 62 and driving serrations 64 are lubricated through passages 9 which are positioned rearwardly of another increase in the diameter of the bore. The lubricant then flows rearwardly through the tube 74, the inclined passages 80, Fig. 3, in the nut 76 to the splines 81 transmitting the power from the turbine to the compressor. From the splines, the lubricant flows to a chamber 23 and a well 26 supplying oil to the turbine bearing 25. The tube 74 is held in position by bushes 75 in the shaft 85 and by a spring-loaded flanged bush 37 in the shaft 10. The oil for the front bearing 50 is supplied from an independent source. A screw. thread may be formed on the wall of the bore adjacent to the point 8 to pick up and impel the oil rearwardly. In a modification, the tube 74 leads to a bore in the stub shaft 82 and radial holes pass the lubricant to the chamber 23.

Abstract: 541,255. Locking gear for lifts and the like. PRESTON, P. July 4, 1940, No. 11216. [Classes 78 (ii) and 78 (iii)] A safety locking gear for lifts, hoists &c., of the type in which a control rope; chain, or like manually operated member 1 passes through the interior of the lift, has a gripper 3 for holding the member 1. The gripper has projections 8 taking between links of the chain 1 and is normally pressed by a spring 7 to slide into such engagement. A catch 14A abuts against the nose 13 of the gripper 3 to hold it in position. The gripper is released to free the chain 1 for pulling by the operator to start the lift by two handles 11, 12 permanently attached to one another by a length of chain 19. These handles have angular boss extensions 17 whereby they can be passed through similarly shaped holes in the gear casing 2 and then into mating sleeves 10, 14 only when the latter are in the positions they assume when the member 1 is locked. The sleeve 10 carries two teeth embracing a pinion 9 on the gripper 3, and the sleeve 14 is unitary with the catch 14A. Operation of handle 12, first to withdraw the catch 14A against the pressure of a spring 15 frees the gripper 3 and allows handle 11 to be turned to move the gripper and release the chain 1. The handles 11, 12 can be taken away from the casing 2 only after the gripper returns to engaging position, and can be employed to open respectively the landing door and the lift door, the length of the chain 19 ensuring that the lift shall be near or at the landing point before this is done.

Patent GB-115690-A (GB)
IPC: A01B39/06
Abstract: 115,690. Gill, H. A., (Beeman Garden Tractor Co.). May 16, 1917. Cultivators.-A motor-driven cultivator is provided with a steering and operating hand lever or post which, in addition to being used for steering in the ordinary way, is rotatable about its axis to shift the cultivating- implements transversely independently or simultaneously with the steering movements. The direction of travel of the machine can thus be changed, as when meeting an obstruction, without affecting the position or course of the cultivating or other ground-working implements. Adjusting-means are provided to regulate the lateral and vertical positions of the implements. In the arrangement illustrated, the crank-shaft of the engine 2 is preferably concentric with the traction-wheel axle 8, the casing being supported thereon, and the drive transmitted to the wheels 4 through gearing 6. A draft bar 12 is connected to the rear of the engine casing by horizontal and vertical pivots 11, 13, Fig. 4, and has bolted thereto hangers 14, from which extend laterally horizontal plates 15<1> with extension plates 17. The hangers 14 also carry rods 23, to which trailer arms 24 for castor wheels 26 are adjustably clamped, thereby allowing the depth of cut to be regulated. The ground-working implements 20 are adjustably secured in slots 16 in the plates 15', 17. The steering bar or post 27 is rotatably mounted in a footstep bearing 28 pivoted at 29 to the engine casing, rotary movement of the post being, however, limited by a lug on the bearing 28 co-operating with shoulders on a collar 30 secured to the post. A sleeve 33 clamped to the post is formed with an adjustable depending arm 35 pivotally connected to an horizontal pin 37 carried by the draft bar, so that rotary motion of the post about its axis shifts the bar 12 and implements to one side or the other without affecting the steering of the machine. Similarly, the steering may be effected without diverting the direction of travel of the cultivators. The post 27 is connected to the upper part of the casing by a collar 46 and tie-rod 45. The clutch and throttle controls may be operated by levers 42, 43 acting under transmission means passing through the post 27. A small plough may be attached to the rear of the machine, in addition to the cultivators shown.
