Abstract: 835,652. Removal of glass chips from glass surfaces ; cleaning glass sheets. PITTSBURGH PLATE GLASS CO. March 7, 1958 [April 15, 1957 (2)], No. 7386/58. Classes 56 and 138(1). To facilitate the removal of one or more glass chips from the surface of a supported glass sheet, a body having a rigid contacting surface is pressed against the glass chip on the supported sheet with a force sufficient to pulverize the chip to form smaller glass particles. A steel platen may be brought down to crush the chips but not so as to put pressure on the glass sheet, or a rigid tool may be manually pressed on the chips, the glass particles then being removed by brushing. In a preferred arrangement, a steel roll is incorporated in a washer through which the glass sheet is passed, as shown in the Figures. The washer comprises pairs of rubber covered pinch rolls 60, for conveying glass sheets G through the washer, mounted on shafts 61, the lower shafts 61 having at one end sprockets engaged by a chain 65 passing over idler sprocket 66 and driven by a motor, and upper and lower shafts 61 being connected by gears 68 at the other end. Nylon brush rolls 70 are mounted between the rolls 60 on shafts 71 each having sprockets 72 which are engaged by a zig-zag chain 73 so that rolls 70 are rotated in the opposite sense to their adjacent rolls 60. Spray pipes 81 and 82 are mounted above the rolls 60 and 70, the pipes 82 being fed into water containing a detergent and pipe 81 with rinse water. A glass chip crusher roll assembly 90 is mounted before the last pair of rolls 70 and the rinsing spray pipe 81 to pulverize any chips remaining on either surface of the glass G. The assembly 90 comprises two sets of steel roll 116, pilot roll 118 covered with a rubber sleeve 119 and rubber sleeved roll 120 so positioned that rotation of roll 118 causes rotation of roll 116 by frictional engagement with roll 120, and roll 116 is positioned about 0À002 inches from the plane of the sheet G. Top roll 118 is mounted to be below the plane of the sheet G and is moved by the sheet against a spring 105, movement being limited by a set screw 103 and the lower roll 118 is mounted to lie in the plane of the sheet G so that the rolls 118 are rotated by the friction of the sheet. In a modification, a single steel roll is spaced slightly above the surface of the sheet G with a roll 60 below, the roll being adjustably mounted. In both cases, two crusher assemblies may be positioned side by side to take pairs of glass sheets coming from the pattern cutters.
