Title: Improvements in hoists
IPC: E06C7/12
Filed: 1946-08-21
Abstract: 615,789. Hoists; winding gear. HAMP, A.H Aug. 21, 1946, No. 24915. [Classes 78 (iii) and 78 (v)] A hoist comprises a mast along which a trolley is raised or lowered, a power unit, a winding drum for the hoisting cable of the trolley, a friction wheel or disc associated with the winding drum and adapted for co-operation with a friction pinion on a shaft driven from the power unit, the friction wheel or disc being movable bodily from an inoperative position in which it is clear of the friction pinion and in contact with a brake to hold the winding drum and hence also the trolley stationary, to a fully operative position in which it co-operates with the pinion to wind-up the hoisting cable to draw the trolley up the mast, and also to an intermediate position clear both of the brake and the friction pinion so that the winding drum can rotate freely to allow the trolley to travel down the mast under its own weight, an operating member for moving the friction wheel or disc from the brake position to the driving position, and vice versa, and also for holding the wheel or disc in the intermediate position, and a part which is movable with the operating member and notched or equivalently formed for co-operation with a spring- or weightcontrolled catch or detent to hold the friction wheel in contact with the friction pinion at required times. 'The Figures show the application to a builder's hoist wherein the mast comprising sections 1; 2, 3 is mounted on a carriage 9 and the trolley 53 is raised by a cable 18 passing round pulleys to a winding drum 35, Fig. 3, housed in a casing 22, Fig. 1, on the carriage. The drum is mounted on an eccentric portion 33 of a shaft 32 whereby on turning the shaft by means of a handle 39, Fig. 6, the drum may be moved bodily to bring a friction wheel or disc 36 integral with it, into contact with a driving friction pinion 31 so as to rotate the drum, or into engagement with a brake block 37 to secure the drum against movement, or to an intermediate position to allow free rotation of the drum independent of the drive. The driving pinion 31 is mounted on a shaft 24 driven through chain-and-sprocket gearing 26, 27, 28 from a shaft 25 of a petrol engine 23. When the handle 39 is raised to the dot-anddash line position, Fig. 6, to bring the friction wheel 36 into contact with the pinion 31, a shoulder 46 on a catch lever 42 engages a notch 47 in a cam disc 41 on the boss 40 of the handle to lock the parts in this driving position. When the trolley reaches the desired level, it engages a trip lever which is pivotally mounted on the runway and connected to the catch lever 42 by a cable 60, yoke 59 and rod 58, so as to release the handle which then falls to move the wheel 36 into engagement with the brake block 37. The position of the trip lever can be varied. The supports 57 of the trolley platform 56 may be adjusted lengthwise to vary the angle of the platform. Release of the handle may be effected by hand.

Abstract: 1,020,153. Securing vehicle wheels. FEDERAL SCREW WORKS. June 24, 1963 [June 25, 1962], No. 24956/63. Heading B7C. [Also in Division F2] A spindle 10 (Fig. 1), which rotatably supports a wheel hub 12, has a threaded end 20 and adjacent thereto a non-circular shoulder portion 22, the hub being retained on the spindle by a nut 28 which urges a non-rotatable washer 24 against a race 42 of bearing 16. Fig. 3 (not shown) illustrates the shoulders 26 of the aperture in washer 24, which mate with portion 22 of the spindle, so that the washer may move axially, but any rotation of race 42 on the spindle will not be transmitted to the nut 28. The nut 28 has a wide portion 32 which has flats (36) (Fig. 2, not shown), to receive a spannerwhen the nut is tightened, and a narrow portion 31, which is deformed by indentations (37) so that it binds on the thread 20, while still being rotatable thereon. Instead of the aperture of washer 24 and portion 22 of the spindle being hexagonal as shown, they may be circular with two flat portions or star-shaped in section (Figs. 4 . . . 7, not shown). Fig. 8 (not shown) illustrates a similar arrangement used to support a pivotable arm on a stud, using sleeve bearings. Figs. 9, 10 (not shown) illustrate similar support of a pulley wheel and a lever respectively.

Patent GB-996590-A (GB)
Title: Improvements in or relating to apparatus for winding rovings
IPC: D01H1/36
Filed: 1961-07-11
Abstract: 996,590. Roving frame. T. MORIKAWA. July 11,1961 [July 11, 1960], No. 25006/61. Heading D1D. A roving frame in which roving is fed at constant speed from drafting-apparatus comprises a bobbin shaft, a flyer, both of which are prevented from moving axially, and drive-means for rotating the bobbin and flyer at different relative speeds, a presser reciprocated along the flyer, and differential gear means in the drive-means for varying the difference in the relative speeds of the bobbin and flyer as the diameter of the winding increases. Means may additionally be provided for avoiding changes in tension in the roving due to movement of the presser towards and away from the drafting rollers. In Fig. 2, the bobbin shaft 24 is rotated at gradually reduced speed from a shaft 5 Fig. 6 through a double-cone arrangement 6, 9 and a differential 13, and the flyer spindle 42 is rotated at constant speed. One arm of the flyer houses a rotatably-mounted interchangeable shaft 45 with a double helical screw engaged by a projection on a member 31a carrying the presser which is consequently traversed along the bobbin with rotation of the flyer as the shaft 45 is rotated from the bobbin shaft by gearing 47. The speed of traverse accordingly reflects the difference between the speeds of the flyer and the bobbin. In Fig. 7, the presser is held magnetically or otherwise to rotate on a rail 32 traversed by threaded rods 34 driven from the lower cone 9 through a reversing- clutch 26, Fig. 6. The tension in the roving is additionally controlled as follows. (a) A pulley 59 over which the roving passes to the presser is attached to one end of a highly expansible spring which is attached to the flyer at 57 and is trained over a fixed pulley 60. (b) A pulley 59 over which the roving is trained on its way to the presser 31 is slidable in a slot in an arm 56 of the flyer and rotates with the flyer in a rail 61 riding on a threaded rod 62. This is rotated from the shaft 29 which drives the rod 34 which traverses the presser-rail 31, the gearing between the shaft 29 and the rods 34, 62 being such that rod 34 is driven twice as fast as rod 62. (c) The bobbin shaft 24, Fig. 6 is driven from the output side of a second differential 48, the input of which comprises planets 50a carried by a gear 51. Gear 51 is driven via gear 55 and a train 27 from reversing- clutch 26, while planets 50a are driven via gears 50, 49, 16 from the input side of differential 13. Hence, according to the position of the reversing- clutch, i.e. according as to whether the guide 31 is rising or falling, a component corresponding to the traverse-speed is added or subtracted from the drive of the bobbin 24, to increase or reduce its speed of rotation.

Abstract: 866,682. Leather-working machines. MERCIER FRERES. Aug. 7, 1958 [Sept. 26, 1957], No. 25309/58. Class 76. [Also in Group XXIV] In a machine, such as a tannery machine, having moving parts, some of which are protected by a cover while others are exposed, the cover, or a part thereof, is movably mounted and associated with an electric switch controlling the exposed moving parts so that any shock or force exerted on the cover (e.g. by an operator who has lost his balance) causes the stopping of the exposed parts. The tannery machine shown comprises a bladed roller 2 which is belt-driven by a motor 3, a roller 5 which is chain-driven by a motor 13, and one or more conveying rollers 6 on an arm 7 which is oscillated between open and closed positions by an eccentric mechanism 16. The mechanism 16 is driven by the motor 13 through a coupling controlled by a pedal 18. When the arm 7 is in the closed position the conveying rollers 6 lie adjacent to and are driven by a gear fast with the roller 5; alternatively the conveying rollers may be driven by a belt which is tensioned only when the arm 7 is closed. The upper part of the machine is protected by a fixed cover part 19a to which is hinged, e.g. by a flexible plate, a movable cover part 19b associated with a microswitch so that any displacement of the part 19b stops the motor 13 and applies a brake associated therewith. In a modification the whole cover is in one piece and is movably carried by swinging links, Fig. 5 (not shown). In addition to the movable cover or cover part, the machine may be provided with switch-actuating tripbars such as 24, Fig. 7, in front of dangerous spaces, the bar co-operating with a microswitch 25. The pedal 18 also has a pivoted guard 26, or a trip-bar, co-operating with a microswitch. All the microswitches are connected in series with the coil of a contactor circuit-breaker for the motor 13, the circuit, Fig. 10 (not shown), including remote stopping and starting switches, a local starting button and a thermal relay.
