Abstract: 532,731. Shoe finishing machines ; waxing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and MINETT, W. T. July 29, 1939. No. 22066. [Class 95] A machine for use in finishing, e.g. waxing and polishing, a bottom portion of a shoe comprises a frame, a plurality of devices for applying finishing material to the shoe bottom portion, and means for operating on the bottom portion after the application of the finishing material, the applying devices being so mounted in the machine that one or other thereof may be moved into an operative applying position, and said means being mounted in a stationary portion of the machine frame. Such a machine, shown in Figs. 1-3, comprises a frame 1, 3, 5, 7, carrying a driven horizontal transverse shaft 13. A triangular carrier bracket 17, 19 is provided on a bearing 15, and is provided with bearings 25, each adapted to receive a driven horizontal shaft 33 carrying a deformable and detachable waxapplying roll 31. The carrier bracket 17 is swingable about its bearing 15 to bring either of the wax-applying rolls 31 into operative position, stops 55, 57, 63, and a locking bolt 59 being provided. The weight of the carrier bracket and supported parts is balanced by a spring 64. Casings 29 partially surround the rolls 31, and each roll is heated by electric elements 75, and is provided with an adjustable wax-distributing and re-forming roll 91. The orientation of each casing with respect to the frame and with respect to the axis of the shaft 33 is preserved, whatever the position of the carrier bracket 17, by means of the toothed quadrant 97, idler pinion 99 and semi-circular toothed arm 103. Two electrically heated and thermostatically controlled wax-pots 105 are provided, one for use with each wax-applying roll, to supply wax of appropriate colour thereto, and they are mounted on a member 107, pivoted about a vertical pivot 109 so that either wax-pot may be brought into wax-supplying relationship with its associated wax-applying roll, when the latter is in operative position. Flow of wax from the pots 105 is controlled by spring - pressed plungers 125. Means for operating upon the work, e.g. the edge face of a heel, after wax has been applied thereto, comprise a polishing roll 141, a polishing brush 177 and a seat-wheeling tool 179. The polishing roll 141 is removably mounted upon a driven shaft 143, and is partially surrounded by a hood 157 connected to dustextracting means comprising a driven fan. The removable driven polishing brush 177 is partially surrounded by a hood 181 connected to the dustextracting means, and the removable seat-wheeling tool 179 is heated frictionally by means of a friction clamp 197. In the modified machine shown in Figs. 4 and 5, a carrier bracket 209, of reversed S-shape, is journalled on a sleeve 213, and carries and partially surrounds the two driven wax-applying rolls 207. Drip pans 210 are provided. The carrier bracket 209 may be swung through 180 degrees about the sleeve 213 to bring one or other of the rolls 207 into operative position, stops 249, 251, 253, and a locking bolt 255 being provided. The rolls are electrically heated by elements 261 mounted in adjustable and pivoted secondary casings 263. The waxpots 281 are mounted on a member 283, swing- able about a vertical pivot 284, and carrying symmetrical arms 287,288 which co-operate with unsymmetrically arranged arms 289, 291 on the carrier bracket 209, to ensure that each wax-pot supplies wax of appropriate colour, only to the wax-applying roll with which it is correctly associated. Specification 424,338, [Group VII], is referred to.
