Title: Improvements in or relating to machines for attaching heels to boots or shoes
IPC: A43D79/00
Filed: 1936-05-20
Abstract: 475,579. Heel - attaching machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., PRATT, J. W., and KESTELL, T. A. May 20, 1936, No. 14251. [Class 17 (i)] Mechanism of the kind described in Specifications 451,350 and 451,410, for positioning a shoe in the machine relatively to a heel, is improved. The flexible shoe positioning band extending around the heel end portion of the shoe is engaged at spaced apart positions by means pressing these portions of the band firmly against the shoe. The pivoted members supporting the end portions of the band permit relative movement of the members and band lengthwise of the shoe, and the heel end portion of the band is engaged by a member movable lengthwise of the shoe and urged forwardly by a spring. In one form, the pair of pivoted levers 39, which close the ends of the flexible band 31 on the shoe, are each slotted to engage a pin 35 carried by an arm secured to the band and having a rounded abutment 45 engaging the lever. The rear of the band has a block 49 carrying a pin 51 engaging a socket in which it is, normally, retained by a spring plunger 55. A forked member 61 engaging the band is guided to slide longitudinally of the shoe, and is urged forwardly by a spring 63. In a modification, the ends of the band are turned back so that they may slide over abutments carried by the ends of the pivoted levers. To enable the arms 39 to be swung laterally when positioning a shoe in the machine a hand lever 80 may be secured to the stud 77 integral with one of the arms and passing through the sleeve 79 carrying the other arm. To allow the actuating cam to follow this lateral movement of the arms its spindle 69 is not mounted in the band clamp slide 86 as described in the prior Specifications, but in a member 82 pivoted on a pin 84 mounted in the slide. A bracket 92, also secured to the slide is bored to allow play to the shaft 69 and form a pivot for an arm 88 actuating the cam as described in the prior Specifications. The arm is connected with the shaft 69 by an Oldham coupling comprising projections 98, 100 at right-angles on a ring 96 engaging recesses on a collar 94 secured to the shaft and the arm 88, respectively. Stops limit the lateral adjustment of the arms 39.

Abstract: 670,196. Chocolate refining roller apparatus. BAKER PERKINS, Ltd., and ANCIENS ETABLISSEMENTS A. SAVY, JEANJEAN ET CIE. May 19, 1950 [May 30, 1949], No. 14467/49. Classes 59 and 86 A multi-roll chocolate refining machine or similar multi-roll machine in which a feed roll is provided for supplying material to be treated to the lowest or first refiner roll and having nip adjustment means for the feed roll at each end thereof, includes a displaceable abutment for each adjustment means, said abutments being connected to a common member dependent upon a single shear pin, the arrangement being such that any displacement of the feed roll due to the entry of an obstruction in the nip causes the pin to shear. Each end bearing of a feed roll 1 of a multi-roll chocolate refining mill is carried by a pivoted lever member 3 adjustable about its pivot to move the roll 1 to or from the first refining roll by means of an adjustable thrust rod 8 contacting a normally fixed abutment 9. Each abutment 9 is formed as one end of a bell-crank lever pivoted on a fixed shaft 10, Fig. 3, whose other end is pivoted to a common bar 12 extending across the mill parallel with the roll axes. The bar 12 is formed with a transverse orifice 14 at one end which is engaged by a shear pin 13 secured to the mill frame, so that if an obstruction enters the mill and pressure on one or both end bearings increases the shear pin 13 breaks and the pressure at both ends of the mill is relieved. Movement of the bar 12 consequent upon shearing of the pin 13 causes a limit switch 21 to operate to stop the mill motor.

Abstract: 1,267,774. Sorting apparatus. SPHERE INVESTMENTS Ltd. 26 March, 1970, No. 14840/70. Heading G4H. [Also in Division G1] In apparatus for accepting or rejecting articles, e.g. rocks as they fall past a deflector 20 (Fig. 1) the articles are carried (by a conveyer belt 12) past a sensing head 17 which delivers a signal representing the time the article is in front of it to a gate 41 (Fig. 3) which simultaneously receives pulses of a frequency corresponding to the belt speed so that the count in a counter 27 represents the length of the article. The count controls logic circuitry 30 which if the article is to be rejected, indicated by a blast signal 37, shortens the length of the signal to allow for the fact that the object is accelerating past the deflector and stores the modified signal in register 31 which is stepped at a rate dependent on the belt speed so that when the article reaches the deflector one or two of the register stages'enables blast control 21 for the time taken for the article to pass the deflector. The blast signal 37 is generated by a sensor 17 which is preferably photo-electric and compares signals representing characteristics of the article with predetermined levels. The belt speed sensor preferably comprises a magnetic pick-up sensing magnetic slugs on the conveyer belt. The logic circuitry 30 comprises NAND gates 50-58 controlled by the stages of the counter 27 so that a number of adjacent "1" bits are stored in the register 31, the number representing the time the article will take to pass the deflector and the position of the first "1" representing the time at which it will arrive at the deflector.

Title: Improvements relating to Apparatus for use in the Directing of Anti-aircraft Guns.
IPC: F41G5/08
Filed: 1918-09-16
Abstract: 131,192. Marshall, J. r., and Metropolitan Carriage, Wagon, & Finance Co. Sept. 16, 1918. Electric and magnetic speed indicators.-Relates to means for use in sighting guns whereby a movement proportional to the product of two quantities can be obtained, and consists in the combination of (1) an electro-magnet the excitation of which is varied with one quantity, (2) a metal disk rotating in the field of the magnet at a speed which is varied with the other quantity, and (3) means movable under the interaction of the field and disk. In the form shown in Fig. 2, a metal disk c mounted on a shaft d carried by a lever e riding loosely on a shaft h is caused to rotate in the field between the poles b of an electro-magnet a by gearing ! i from the shaft h. The interaction between the field and disk causes the lever e to rotate round the shaft h until the torque on the lever is balanced by that due to a counterweight f, assisted by springs. If the excitation of the electro-magnet a is varied with the time of flight of a projectile, and the speed of the shaft h is varied with the angular velocity of the gun-sights, the deflection of the lever e will be proportional to the product of these quantities, i.e. to the defection angle required for speed of target. The deflection of the lever e may be read off directly, or may be caused to actuate a switch controlling an electrically-driven indicator. In the example shown in Figs. 4 and 5, the lever e is connected by a link k to a lever j which, when displaced into contact with either of the levers l, is adapted to close the circuit of a motor driving any suitable indicator. The levers l are drawn together by a spring m but are normally kept out of contact with the lever j by the interposition of a lever n which is also adapted to be rotated through suitable gearing by the motor that drives the indicator. If the lever j is displaced by the lever c into the position shewn in Fig. 5, it closes the motor circuit and drives the indicator and the lever n until this lever, followed by the left-hand lever l, reaches the right-hand lever l and pushes it out of contact with the lever j, when the motor stops. Movement of the lever j to the left is adapted to start the motor in the opposite direction.
