Abstract
194,441. Chance Bros. & Co., Ltd., and Forster, A., L. Dec. 23, 1921. Rolling.-Glass rolling machinery, particularly for rolling a sheet from a pot or charge of molten glass, is provided with means for dividing the sheet into plates or portions of the required length, and with means for imparting an additional forward or accelerated movement to the receiving table, each time a cut is made, in order to carry the plate clear of the succeeding plate. The machine comprises rolls a, b, Fig. 1, which roll a charge of metal into a sheet h in the usual manner, the sheet being received on a moving table q. The cutting-device consists of a roll d, Figs. 1 and 5, having a slot e which is entered by a blade c when the blade is depressed by a toggle linkage operated by a compressed air cylinder m. The blade c is normally supported by a rest g clear of the glass sheet, but a catch f, projecting from the end of the roll, engages the blade at the proper times and pushes it forwards, thus allowing it to be forced into the slot e and cut the sheet. The blade slides in slots in side frames i which swing about the shaft l on the roll d. The movement of the blade by the catch f causes it to swing until withdrawn by the cylinder, so that it moves with the sheet while making a cut. In order to ensure that the blade is withdrawn from the slot e at the proper time, the frames i are formed with cam slots o that are engaged by rollers p carried by a fixed support. The slots o are of such a shape that they lift the frame i until the blade is clear of the slot e. The frame then swings back to its initial position. The table q which receives the sheet is moved by a pinion which is driven from a shaft u, Fig. 8, through a differential gear v, w, y. In order to give an additional movement when the sheet is cut, a ratchet 3, which engages a pawl secured to the toothed annulus y, is reciprocated, thus moving the annulus and increasing the normal velocity of the gear train. The ratchet is oscillated by a reciprocating rack 12 which is automatically connected with the driving-shaft when the cutting-blade is depre&sed and is released at the completion of its return stroke.
