Title: Improvements in and relating to inclined conveyors, escalators and the like
IPC: B66B29/00
Filed: 1925-04-01
Abstract: 232,582. Otis Elevator Co., (Assignees of Margles, S. G., and Handy, A. E.). April 17, 1924, [Convention date]. Driving-gear; tensioning; stopping on breakage of chains.-In an electrically-driven chain or belt conveyer in which the driving sprocket 14 gears with both runs, means are provided for stopping the motor and applying a brake to the sprocket when a break or other abnormal movement occurs on either side of the sprocket. A member 16, around which the chain passes at the upper end of the track, is capable of longitudinal movement and is pivotally connected by a link 29 to the short arm 30 of a lever 27. The outward pressure on the member 16 is varied by adjusting the position of the weight 33 on the lever. Pins 37 at the end of the lever are arranged between the forked end 42 of a lever 41 which normally retains in vertical position an arm 401 pivoted at 402. A lever 40 carrying the movable member 39 of a switch in the circuit of' an electromagnet 47 is normally supported by the arm 401, but if the chain breaks, the long arm of the lever descends, the pins 37 displace the lever 41, and the arm 401 is moved from beneath the lever 40, thereby breaking the circuit. Similar mechanism is arranged at the lower end of the conveyer, but the lever is arranged to draw the member 16 towards the conveyer. A toothed drum 43 attached to the sprocket 14 is engaged by a detent 45 when the chain breaks. The detent is mounted on a lever 46 which is controlled by the electromagnet 47 and carries part of a, switch 48. When the switch 48 is open the supply of current to the motor is cut off and a brake (not shown) is applied to the motor shaft. In a modification, springs are used to move the members 16. A wiring diagram is given in the Specification.

Title: Improvements in or relating to suction cleaners
IPC: A47L9/04
Filed: 1940-05-20
Abstract: 541,309. Vacuum cleaners. HOOVER, Ltd. May 20, 1940, No. 8937. Convention date, July 8, 1939. [Class 8 {i)] The rotary agitator of a suction cleaner carries rigid beaters 3 mounted at an adjustable distance from the axis. The adjustment may be effected by a cam 12 on a transverse axis which moves the beater outwards against springs 8 attached to the bed in which the beater lies, and looped over studs on the beater. Alternatively the motor driving the agitator may have two alternative speeds, and according to these speeds the beater is projected outwards to different distances by the centrifugal force acting against the springs 8. The agitator may also carry brushes 21, Fig. 12, connected by links 25 to the beaters, and moving pivotally against coil springs 22 ; thus the beaters moving outwards under centrifugal force at one of the two speeds draw the brushes inwards. The springs 22 oppose 'the outward motion of the beaters; light leaf springs which assist the outward motion prevent chattering.

Abstract: 1,111,283. Slubbing flyer. FAIRBAIRN LAWSON LTD. 2 March, 1966 [3 March, 1965], No. 8984/65. Heading D1D. A flyer for a spinning machine has a part-cylindrical leg along the inner surface of which the yarn normally passes to eyelets at the bottom of the leg, an aperture being provided in the upper part of the leg so that if the yarn breaks, it will pass under centrifugal action, through the aperture to be severed by an adjacent breaker-plate, and will not wrap itself around the outside of the flyer. The part-cylindrical leg is wider at the top than at the bottom. At the bottom it has two eyelets with threading-slots. At the top, it has a flange 10 with an upward extension by which it is mounted to rotate in a rail 19 a flange 18 depends from the rail and prevents the yarn lapping around the upper part of the flyer. Inside the flyer, depending from the flange 10 and integral with the flyer, is a flange to which a guide pin 13 is secured. Yarn passing downwardly through the flange 10 is guided around the pin along the inner surface of the flyer, to the outside of the flyer through one of the apertures, and back to the inside through the other aperture, and thence to the package through the other. Near pin 13 a D-shaped aperture 17 is provided in the flyer. A plate 20 depends from the flange 18 to a level below that of the aperture 17. If the yarn breaks, the broken end is thrown out centrifugally from the aperture and is severed by contact with the plate as the flyer rotates. The plate, has an extension 24 to stop the end riding downwardly off the plate.

In Figs. 1, 2 3 and 5, the rotor 53 comprises a central tube 14 rotatably mounted at each end by a bearing 13 on a sleeve of the shaft 10. Mounted on the ends of the tube 14 are elongate plates 24 between which extend the two soil-working members 33. Each soil working member 33 includes a tube 27 to which are secured two rows of curved tines 32; alternatively, the pairs of tines are grooved and integral, and are clamped between two half-tubes. The transmission at each end of the rotor 53 is formed by a sprocket 44 integral with each sleeve 11, a chain 45, and a sprocket secured to the tine tube 27. The rotor 53 is rotated from the tractor powertake-off via gearbox 38, sprocket 36, chain 35 and a sprocket 34 integral with a sleeve 24A fastened to the adjacent elongate plate 24. The shaft 10 may be rotated slightly by means of setting levers 52 in order to adjust the angle of attack of the tines 32 to the ground. A jacket 18 is provided on the rotor 53 for directing the inverted slices of soil raised by the tines 32 back into the furrow.

Abstract: 862,295. Control of A.C. motors. GENERAL ELECTRIC CO. Ltd. March 16, 1959 [March 27, 1958], No. 9840/58. Class 38 (3). An induction motor 1 having a wound rotor is braked by disconnecting the motor from an A.C. source and by supplying two of the primary windings with D.C. from a rectifier 8 through contacts 13c and 13e. The rectifier is connected to an auxiliary generator through a protective saturable reactor 9 and a transformer 11. In order to obtain creep speed control, or in the event of failure of the main power supply 4, contacts 13a-13f are operated in cyclical succession in pairs so that pulsating current of frequency corresponding to the frequency of operation of the contacts is fed to the primary windings of the motor. During such operation, the slip-rings of the motor are shortcircuited. The contacts 13a-13f may be operated in automatic sequence whereby each main contact by means of auxiliary contacts operates a following main contact after a predetermined time delay, and is then disconnected by an auxiliary contact on this following contact. In another arrangement, a motor-driven contact drum has six contact brushes spaced around it, the drum having a sector engaging the brushes successively in pairs. By introducing direct current into the rotor circuit, the motor may be operated as a synchronous motor when supplied with pulsating current, so affording accurate decking for winder drives.
