Abstract: 1,181,825. Stripping waste from cut blanks. DERITEND ENG. CO. Ltd. 18 Jan., 1968 [21 Feb., 1967], No. 8155/67. Heading B4B. The waste of a cardboard box blank 16, Fig. 1, produced in a cutting-machine 11 is removed by means of stripper rollers 12, 13, the axes of which are located in parallel planes P1, P2. Roller 12 has a resilient surface layer 18, e.g. of polyurethane and roller 13 has secured thereto a sheet-metal forme 20 provided with studs 21. Each blank may be supported, while the waste is being stripped therefrom, by transverselyadjustable parallel wires (30), Figs. 2 and 3 (not shown), or by a plurality of endless belts. The stripped waste may be allowed to fall or such waste is removed by suction. Each stud (211), Fig. 5 (not shown), may be spring-pressed. In a modification, roller 100, Fig. 6, has one or more grooves 101 extending across the width thereof and each engageable by a gripper bar 102 the ends of which are secured to a pair of parallel endless chains 103 passing over sprockets 104, 105. Each gripper comprises a fixed finger (110), Figs. 7 and 8 (not shown), and a movable finger (111) which is spring-urged to the open position. Cam means provided on an angularly movable and forwardly displaceable shaft (115) are engageable with fixed cam-plates 120, the arrangement being such that the fingers (110, 111) first remove the waste and then grip the leading edge of the blank, the blank being released to drop on to a stack-forming table 140.

Abstract: 670,918. Time switches; make and break switches, mechanical. BARBERA, C.U. March 31, 1950. [March 31, 1949] No. 8158/50. Class 38 (v). A rotatable disc 3, fixed to a shaft 2, has holes 4 around its edge to receive pegs 5 which may be placed where necessary to produce switching operations. at desired times and intervals. The pegs 5 co-operate with a ratchet wheel 6 fast on a spindle 7 carrying a contact arrangement comprising toothed insulating discs 11, 13 and a toothed conducting disc 12. Contact brushes 17, 18, mounted in supports 15, are urged into engagement with the teeth of the discs 11 ... 13 by springs 20 and a brush 16 permanently engages a conducting disc 9, which is connected to the conducting disc 12. A friction brake 19 bearing against an insulating disc 10 prevents reversal of movement of the discs. The arrangement is such that as the spindle 7 is rotated step-by-step, the teeth of discs 11 ... 13 move past brushes 17, 18 thereby making and breaking the circuits connected thereto. The discs 11.... 13 are relatively adjustable, being clamped in position by a nut 14, the number of teeth on each disc, and the number of each type of disc, being optional. The pegs 5 may co-operate with two contact arrangements 11 ... 13, the pegs 5 either being all on one side of disc 3, Figs. 4-6 (not shown), or some on each side, Figs. 7-9 (not shown). Several discs 3, each co-operating. with one or more sets of discs 11 ... 13, may be provided.

Abstract: 1,001,185. Control of motors. CHAS. F. THACKRAY Ltd. April 17, 1962 [March 7, 1961], No. 8253/61. Drawings to Specification. Heading H2J. A fluid-pressure valve is adjusted to a number of desired settings by means of an electric motor associated with push-button switches for starting and cam-operated micro-switches for stopping the motor. A plurality of cams are arranged each in a different angular position on a common shaft rotated by the motor, the arrangement being such that the cams actuate associated switches to open the motor circuit each at a different setting of the valve. Each pushbutton switch corresponds with a different predetermined valve-setting and is connected with a separate cam-operated switch, the pushbutton switches being interlocked so that only one can be closed at a time. The motor is coupled through reduction gearing with a driveshaft which is extended to form the cam-shaft. A cam integral with the drive-shaft is associated with valve opening and closing means so that as long as the motor is energized it cyclically opens and closes the valve. An indicating lamp is associated with each push-button.

Title: Improvements in or relating to machines suitable for use in applying coating material to workpieces in the form of shoe parts
IPC: A43D25/18
Filed: 1960-03-15
Abstract: 941,190. Coating-apparatus. BRITISH UNITED SHOE MACHINERY CO. Ltd. March 15, 1960 [March 16, 1959], No. 9046/60. Heading B2B. A machine for applying a stripe of coating material to marginal portions of a workpiece in the form of a shoe part having an irregularly curved outline, has a nozzle for extruding coating material on to the workpiece as it is fed therepast, and means responsive to variations in the curvature of the edge of the workpiece for varying the amount of material extruded from different parts of the nozzle across the width of the stripe, in accordance with the varying curvature of the edge. The invention is described as applied to a machine as disclosed in Specification 467,562, in which the margin of the workpiece is fed by rollers 20, 22 (Fig. 1), its edge being engaged by guide rolls 46 and 48 and underlying fingers 50. Cement is supplied under pressure to a nozzle 52, which is positioned obliquely with respect to the margin of the workpiece. As shown in Fig. 3, the nozzle 52 has a number of outlets 80 to passageways 82, admission of cement to which is controlled by pointed rods 92. Crosspins 94 are fixed to the rods 92 and are engaged in slots 96 in parallel arms 98 (only one shown) which are pivoted on a pin 102 so that an upward or downward movement of the arms 98 by a pin 106 causes progressively greater movement of the rods 92 from left to right of the nozzle, to vary the flow of cement correspondingly. The pin 106 is eccentric on a rotatable shaft fixed to an arm 110, which is connected through a link 112, bell-crank 114, and link 118 to a feeler lever 120. The lever 120 is pivoted on a pin 126 and its lower end 130 constitutes a feeler engaging the edge of the workpiece between the gauge rolls 46 and 48. Concavity or convexity of the edge produces movement of the feeler 130 which is transmitted to the rods 92 and causes increase or decrease, respectively, in the flow of cement towards the right-hand side of the nozzle 52, as shown in Fig. 3.
