Abstract: 338,819. Voltalite, Ltd., and Farrell, H. O. Feb. 15, 1930. Magneto-electric machines; driving arrangements.-In a generator for cycle lighting &c., permanent magnets are carried by a sleeve or a fixed rod, and rotate above the armature, which is mounted on the lower end of the rod. The cores of the armature coils 6 are mounted on a soft iron plate 5 screwed on to a rod 7 which at its lower end screws into a base 8. The base has in it a transverse hole adapted to take a rocker bar 9 on which it is secured by a screw 10 and a lock nut. The magnets 16, which may be of cobalt steel, are carried by cradles 15 secured to a sleeve 13 rotatable on the rod and the upper ends of the magnets are in connection with a soft iron yoke plate 14. Instead of four magnets, as shown, two magnets alternating with soft iron cores may be employed. A pulley 17 having a milled driving edge 18 is mounted on the sleeve. Lubricant may be supplied to the ball bearing 12 through a hole in the pulley normally closed by a spring-pressed ball 20, the bearing plate 22 being perforated for the passage of the lubricant. The casing comprises a bottom plate 24 secured to the base 8 by a set screw, a plate 23 mounted around but clear of the sleeve 13 and having its inner edges upwardly flanged and protected by a skirt portion of the pulley, and a cylindrical portion 25 split down one side so that it can be sprung into position. The armature pole-pieces are cut away as shown in Fig. 4 so that although the cores have a larger diameter than and are arranged nearer the axis than the magnets, the magnets will pass close to the pole pieces The air gap is adjusted by screwing the rod 7. The rocker bar 9 which passes through appropriate holes in the casing. members 24, 25 is mounted in two arms of a bracket 26 and has around it a coil spring 27 anchored at one end to the bracket and at the other end to a pin 28 in the rocker bar. In operation, the spring 27 acting on the rocker bar maintains the pulley pressed against the wheel tyre, but when the generator is out of use, it is turned so that the pin 28 engages with a catch 29 on the adjacent bracket arm. The bracket is pivotally mounted on a clamping arm 31 by a screw 32 and a clamping nut 33. The arm has also a curved slot through which passes a locating screw 35. The bracket can be lifted over the head of the screw 35 so that the generator and bracket can be replaced' in the same position if removed.

Title: Method and apparatus for slitting a roll of sheet material into strips
Inventor: MARKS RONALD HIRSCH
IPC: B26D7/14
Filed: 1963-02-08
Abstract: 1,021,294. Spinning yarns. R. H. MARKS. Feb. 8,1963, No. 5293/63. Heading D1F. [Also in Division B6]. A web e.g. of paper or plastics, is slit into strips (which are subsequently moistened, twisted and, in such moistened and therefore flexible condition, fed to a knitting machine) by rotatably' mounting a roll of the web material, adjusting the tension of the material according to its particular strength (and as it unwinds), splitting strips from the roll and drawing the strips from the roll through the tensioning thereof. In the continuous process effected by apparatus shown in Fig. 1, a  web of paper leaving a rotatably mounted roll 11 is slit by a cutter 14 comprising knives rotating at a speed slightly different from the speed of the material passing therethrough. Cut strips separated by passage through a "rake" 15 are each guided by rollers 19,20, 21, through a trough 18 of water, and then twisted and taken-up on a ring-twister 22. The tension imposed on the web by the take-up means is adjustably augmented by a drive roll assembly 27 wherein the web passes over and under drive rollers 28 and 29. A variable speed motor 37 drives both the cutter 14 and rollers 28, 29, through belt and pulley and chain and sprocket transmission, Fig. 2 (not shown) and enables an operator to select the driving speed appropriate to a particular web. In a modification, Fig. 4, the output of the drive motor or a braking force applied to the moving web is controlled in response to the tension in the material passing through the apparatus so that the (selected) tension in the material is maintained constant. Thus, variation in the tension of material passing across a flat surface of a pivoted plate 39 swings an arm 48 against the restraint of an adjustable spring 41 to move an arm 43 which actuates a tension adjustment on the material or correctively adjusts the motor 46. In the apparatus of Fig. 5, wherein drive rollers and cutting apparatus are separately driven, the arm 43 operates the control arm 44 of a variable speed drive 45 to adjust correctively the speed of the output shaft 47 which drives the rollers 28 and 29. In another embodiment, Fig. 6 (not shown) the shaft 47 continuously rotates the arbor of the roll 11 mounting at such speed as to maintain the tension in the material constant.

Title: Improvements in and relating to washing machines
IPC: A47L15/06
Filed: 1943-04-12
Abstract: 564,907. Washing dishes. BRITISH THOMSON - HOUSTON CO., Ltd. April 12, 1943, No. 5807. Convention date, April 17, 1942. [Class 138 (i)] A machine for washing dishes is combined with a sink 1 having a shredding chamber 21 of the kind described in Specification 552,868, [Group II], with an inlet connected to the drain opening 11 of the sink and an outlet 27 connected to a sewer system for drawing off a mixture of shredded waste food and cold water. When used for washing dishes &c., these are placed in a receptacle which is placed in the sink on which is placed a cover 91. Prior to the washing operation, a stopper device 29, Fig. 2, is removed from the opening 11, and an impeller device is inserted in its place and is adapted to be driven by the fly-wheel 24 of the shredding device through a flexible pin-coupling 78, 79, 80, 81, Fig. 4, which enables the impeller to be coupled while the driving-motor 23 is active. The stopper 29 is connected to the opening 11 by a bayonet-joint, and it can be moved to a position in which liquid drains to the chamber 21 and when in this position a switch arm 42, Fig. 12, is operated by a projection on the stopper to close a circuit containing the motor 23. This circuit also includes a micro-switch 61 normally held open by a spring 57a and adapted to be closed by pressure in the cold water system so as to prevent melted grease from being delivered to the sewer. When used for washing, an impeller member 75 having blades 82 is mounted in the sink opening 11, its casing being constructed to have a bayonet joint connection, and liquid from the sink can pass to the casing so as to be impelled as shown in Fig. 4, over a shroud ring 84 on to the faces of the dishes &c. The liquid is supplied by a mixing tap 2 from hot pipes 5 and cold pipe 6, and the impeller can not be driven until the hot water is under sufficient pressure to close a switch 102, Fig. 12, operated similarly to the switch 61. Closing of this switch 102 causes energization of a magnet 103, and consequent closing of a switch 104 which completes the circuit to the motor 23 provided that the cover 91 is in place to close a switch 94. A heating element 111 is also energized and a thermostatic switch 110 operates to give a warning to the operator to close the tap 3 and to add detergent. The switch 104 can be operated by a knob 112 to stop the action of the impeller. Although there is a gap around the impeller shaft through which liquid can drain, the liquid is normally prevented from draining by the centrifugal action of the impeller blades 82, and if desired of additional blades 88.

Abstract: 528,177. Testing balance of rotary bodies. DUNLOP RUBBER CO., Ltd., and BRAUND, E. T. Feb. 22, 1939, No. 5888. [Class 106 (ii)] A method of testing the unbalance of a tyre comprises (a) placing the tyre in a support so that the combined tyre and support swings as a unit, (b) applying weight to the unit at a point which with the heavy spot of the tyre subtends an angle of less than 180 degrees at the fulcrum of the unit, and (c) utilizing the effect of step (b) to indicate the unbalance on a suitable scale. A horizontal spindle 2 fixed to a vertical standard 1 carries rotatably mounted upon it the support 3 for the tyre. The cylindrical surface of the support may have a slight taper. A graduated disc or scale 5 is secured to the end of the spindle 2 by a bolt 4. Vertically above its centre is a mark 6 indicating the light-spot and vertically below it is the " zero " 7. At a point less than 180 degrees away is a position 8 at which a weight 9 is to be applied. This may be secured to the rim of the support 3 by a spring clip. The tyre is placed on the support 3 and the latter allowed to rock taking up a position in which the heavy spot " is at the bottom. This or the light spot " opposite is then marked on the tyre with chalk. The weight 9 is then clipped in at the point 8 that is the end of the cut-away part 14 of the scale and the support allowed to rock until balance occurs. The position at which the weight stands on the scale indicates the amount of unbalance. In a modification, a segmented scale is fixed back of the drum 3 and a pointer moving thereover is attached to the end of a spindle passing through a hollow shaft 2 the front end of which carries a lever at the lower end of which is a weight which may be secured to the drum. In a further modification, the drum is horizontal and may be lifted off a platform to pivot about a point support. If a weight is used, this is placed on the flange of the drum in line with the light spot and the extent of the retilt towards the horizontal read off on a spirit level. If a weight is not used the level gives the tilt due to unbalance. Magnifying indicating apparatus may be used, or signal devices.
