Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D21/12
Filed: 1930-05-30
Abstract: 355,817. Positive clutches. BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester.- (United Shoe Machinery Corporation ; 140, Federal Street, Boston, U.S.A.) May 30, 1930, No. 16710. [Class 80 (ii).] A shoe-lasting machine is drawn by a worm 890 gearing with a worm-wheel provided with internal ratchet teeth 898. A member 894 is keyed to the cam-shaft and carries a rooking segmental key for engaging the teeth 898 when rocked in one direction, and thus connecting the worm-wheel and cam shaft. This member is rocked by an arm 910, its movement being limited by a pin 906 secured to it and moving in an arcuate slot in the member 894. The arm 910 is urged by a spring 912 to operative position, where it is, normally, held by a latch 918. A pivoted arm 914 carries a plate 916 co-operating with the pin 906. In operation, when the work has been positioned, the attendant swings a toe-presser foot over the shoe. This movement is caused to engage the clutch, connections between the presserfoot and the arm 914 including a pull rod 934 with a hooked end. Near the end of the machine's cycle, a lug 944 trips the latch 918, the hooked rod 934 having been released by a lug 942 shortly after the start of the machine to allow the plate 916 to fall into the path of the pin 906. By contact of these parts the machine is stopped at the conclusion of one revolution of the cam shaft.

Title: Fuel feeding system for gas turbine engines
IPC: F02C9/16
Filed: 1949-06-23
Abstract: 664,807. Gas turbine plant. BENDIX AVIATION CORPORATION. June 23, 1949 [Aug. 3, 1948], No. 16727/49. Class 110(iii) [Also in Groups XXIX and XXXIII] A fuel supply system for a gas turbinecomprises a fuel supply passage with a throttle valve to regulate the fuel flow and means operated automatically in response to engine speed to supply fuel to the burners additional to that metered across the throttle valve when the engine speed attains a predetermined value. The fuel supply to the gas turbine is controlled by a throttle valve 70 operated by an allspeed governor the governed speed of which is pre-set by the pilot's throttle lever acting through a link 32 and levers 31 and 76 on the governor spring 73. The pressure drop across the valve 70 is controlled by a valve 37 operated by the diaphragm 36 and the engine driven speed governor 61. The force exerted on the valve spindle 38 by the governor weights 61<SP>1</SP> is balanced by the pressure drop across the diaphragm 36 so that this pressure drop is proportional to the square of the speed. This pressure drop is proportional to the pressure drop across the valve 70 which therefore also varies as the square of the speed. To enable the fuel supply to be varied with changes of altitude, a control bleed 90 between the chambers 34, 35, a passage 91, a chamber 92, a valve chamber 93, a needle valve 96 and a passage 94 pre provided. The valve 96 is actuated by a bellows 98 responsive to changes in density at the compressor-intake. Assuming that the engine is running at constant .speed, a decrease of density would cause the bellows 98 to expand and the valve 93 to open which will result in a decrease in the pressure drop across it. Since the flow through this valve is the same as that through the bleed 90, a similar decrease in pressure drop will occur across this bleed, which means a decrease in the pressure drop across the diaphragm 36 and a resulting drop across the throttle valve 70. The spring 40 ensures a minimum pressure drop across the valve 70 for idling purposes. The pressure drop between the discharge of the fuel pump 42 and the burner manifold is maintained constant by a diaphragm 50 controlling a byepass valve 45 between the delivery and suction sides of the pump. A valve 100 is provided to supply additional fuel to the burner manifold when a predetermined turbine speed is reached. This valve is operated by a diaphragm 101 actuated by the pressure drop across the diaphragm 36. The speed at which the valve opens may be varied by adjusting the loading of the spring 106 by means of a screw 107. A modification in which the quantity of additional fuel varies with the air density is also described. In this arrangement, the valve 100 is used to control the flow of fuel from the chamber 102 to the conduit 112, and an adjustable stop is provided to prevent further opening of the valve when a predetermined speed is reached.

Title: Improvements in and relating to pit props
IPC: E21D15/58
Filed: 1953-06-17
Abstract: 747,266. Pit props. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES., [formerly GUTEHOFFNUNGSHUTTE OBERHAUSEN AKT.-GES.]. June 17, 1953 [March 2, 1953], No. 16747/53. Class 20(2). A telescopic pit prop has energy storing means which is energised when the prop telescopes under load, the energy-storing means being prevented, by a releasable locking device, from parting entirely with its energy during the dismantling of the prop. In one form the inner prop member 2, Fig. 1, has a cylinder 10 at its lower end engaging over a base plunger 8, and at its upper end a piston 6 engaging within a cylinder 5 carried by the outer prop part 1. The prop parts may be frictionally gripped by a clamp actuated by a lever 3. With the prop parts clamped together and the prop in operative position, subsidence of the roof compresses the air in the cylinder 10, a detent 11 wiping over a stop on the plunger 8. Dismantling is effected by actuation of the clamp lever 3 to release the clamp, whereupon the prop member 2 rises under the high pressure in the cylinder 10, to compress air in the cylinder 5, to a low pressure. Shock occurring at the arrest of upward movement by interaction of the detent 11 and stop, jumps the base 12 free of debris and allows the prop to be withdrawn by an attached rope. The clamp is reapplied immediately after the base has jumped in order to retain the air at low pressure in the cylinder 5. When the prop is repositioned, the clamp is released to allow the low pressure air in cylinder 5 to move the prop head 14 into contact with the roof, whereupon the clamp is reapplied and detent 11 disengaged to allow the high pressure air in cylinder 10 to apply initial loading to the roof. The prop head 14 may be adjusted by a wedge 13. The prop head and/or base 12 may be resiliently connected to their respective prop members e.g. as shown by Fig. 2, a pawl 16 retaining the head or base in pre-loaded condition. Springs or rubber buffers may be employed as the resilient members, and the cylinder and plunger devices at the prop ends may be replaced by chambers 5 or 10 having corrugated walls which are expansible under pressure. The energy storing device may alternatively be provided in a separate base which may be removed from the prop and associated with any other prop. In another embodiment, the prop is spring loaded, Fig. 4 and clamped by a wedge 28 controlled by a wedge 34, which may be retained in inoperative position, by a catch 32 and interengaging stop 29, against spring pressure 30. The subsidence of the roof compresses the spring 20, the energy being retained by interengagement of the stop 24 and detent 16.

Abstract: 835,411. Plying yarns. DEERING MILLIKEN RESEARCH CORPORATION. May 30, 1956 [June 1, 1955], No. 16749/56. Class 120(2) Apparatus for plying strands comprises two strand packages, means for revolving a strand from the first package in a balloon about the second package and including a yarn-storage balloon tension control device, means capable of revolving bodily about the same axis as the balloon and serving to deliver the strand from the balloon and the strand from the second package at positively related linear speeds along paths which converge to a point on the axis of the balloon at which point the strands become plied, and means for taking up the plied strands. In the arrangement shown a strand from package 11 is passed through tensioners 15, axially into ply spindle 16 and radially out therefrom to balloon about a cover 67, inside which is the stationary second package, and thence to the strand flow equalizing device 88. The strand from the second package inside cover 67 is led axially therefrom, around tensioners 78 and thence to the device 88. The two strands then become plied together and pass around a driven take up roller 144 to take up bobbin 152. The arrangement of the plying spindle is detached in Fig. 2 and of the strand flow equalizing device 88 in Fig. 3. The latter includes a shaft 90 rotatably supported in bearings 94 and 96 and having an enlargement 92 carrying two identical capstans 116 having bevel gear teeth which engage with a crown bevel idler gear 126 rotatably carried on shaft 9. This synchronous mechanical coupling of the two capstans ensures the two strands being fed at the same linear speed. To ensure a positive relationship between the rotation of the take up system and the plying spindle they are both driven from the same motor 35. A friction clutch 186 is provided on the drive shaft to the collecting bobbin to ensure a substantially constant tension in the plied cord taken up. Specification 773,891 is referred to.
