Title: Improvements in and relating to apparatus for producing a ground or ground and polished continuous strip of glass
IPC: B24B7/24
Filed: 1942-10-31
Abstract: 561,112. Controlling and actuating apparatus by sounds. PILKINGTON BROS., Ltd., and WALDRON, F. B. Oct. 31, 1942, No. 15351. Drawings to Specification. [Class 118 (ii)] A method of controlling the machinery used for grinding or polishing simultaneously the two surfaces of a continuous strip of glass consists in using the brief train of sound waves emitted by the cracking of the glass. This actuates an automatic device for raising the tool that operates on the upper surface of the glass, or operates a signal device to attract the attention of the machine attendant. The sound of the cracking is received by a microphone which is connected through an amplifier to a relay that controls the circuits of a motor or of a signalling device. The microphone and its circuit are adjusted to respond only to the brief train of sound waves emitted by the breaking glass and not to the sounds accompanying the grinding operation.

Title: Improvements in or relating to machines for performing intermittent operations upon a constantly travelling web
IPC: B26D1/60
Filed: 1930-05-27
Abstract: 348,900. Creasing cardboard. VICKERS-ARMSTRONGS, Ltd., Vickers House, Broadway, Westminster, ROSE, R. W., 65, Alers Road, Bexley Heath, Kent, and SEYMER, V. H., 11, Tedworth Square, Chelsea, London. May 27, 1930, No. 16351. [Class 100 (ii).] A machine for performing creasing or like operations on a constantly travelling web of cardboard, paper, or other material comp:rises tools mounted on upper and lower beams 11, 12 each of which moves parallel to itself in a circular path of predetermined diameter at the same linear speed as the web W. Each beam is carried on a pair of crank pins 13, one at either end, and the beams are preferably built up of steel joists connected by riveting or welding to end housings 14, 15 which carry bearings 16, 17 for the crank pins. In order to maintain the beams vertical during this movement guides 18, 18a are secured to the end housings of the upper beam and have sliding engagement with the housings 15 of the lower beam. The tools are mounted on the lower surface A of the upper beam and complementary tools or dies are mounted on the upper surface B of the lower beam which is designed to provide a free passage through the beam for waste material. For vertical adjustment of the upper beam each bearing 16 is slidable in slots in the end housings and carries a screw stud 20 coacting with a worm wheel 21, the worm wheels being simultaneously operated by worms 23 operated through bevel gearing from a longitudinal shaft 27 which is hand actuated by a cross shaft 31 through bevel gearing 29. The worm wheels are locked after adjustment by nuts 22. Similar means are provided for the adjustment of the lower beam. The crank mechanism is driven from a power shaft 47 carrying gears 48 which drive intermeshing gears 32 mounted on hollow shafts 33. Each of these shafts carries a plate 34 having radial keyways to accommodate an adjustable balance weight 35 which has further radially disposed keys engaging a plate 36 carrying the crank pin for actuating the corresponding beam. A shaft 37 extending through the shaft 33 has diametrally opposed eccentrics 40, 41 which respectively coact with the balance weight and with the crank pin plate. By this arrangement when the shaft 37 is adjusted to increase the throw of the crank, the balance weight is also moved radially outward so that the rotational inertia of the beams is always accurately balanced. Adjustment of the shafts 37 is effected by means of interengaging gears 38 which during operation are forced into locking engagement with the driving gears 32 by nuts 39. The gears 38 are operated from a shaft 49 actuated by worm gearing. The web is fed by feed rolls 55, 56, the latter pair being driven by change gearing 61, 62 from the shaft 47. When the peripheral speed of the tools is altered by adjustment of the crank pins the speed of the web is correspondingly adjusted by alteration of the gear 62.
