Abstract: 285,102. British United Shoe Machinery Co., Ltd., Barclay, W. R., and Woodcock, R. B. Oct. 1, 1926. Polishing and waxing machines. - Machines for finishing boot and shoe bottoms comprise a wax-applying roll having a working surface of fibrous material, a polishing roll also having a working surface of fibrous material, and a flexible-surface rotary polishing pad, wherein (1) the two rolls rotate on an axis or axes extending from side to side of the machine, (2) the pad rotates on an upwardly extending axis with its working face downwards, (3) the wax-applying roll is driven at a lower speed than the other roll. The machine may also comprise a polishing brush, in which case the applying roll, polishing roll, pad and brush are arranged succcessively in the order named from right to left of the machine. In the machine shown in Fig. 1, the waxing roll, polishing roll, polishing pad, and polishing brush are indicated at 5, 6, 7, and 8 respectively. The waxing roll comprises a stockinette cover 27. Fig. 4, on felt 28, which is fixed on a metal sleeve 29. The ends of the cover are clamped against flanges 30, 31 by collars 32, 33 loosely mounted on extensions 34, 35, and the collars are caused to clamp the cover ends by nuts 36, 37. A nut 38 bears against the end of the sleeve 29, and is used to stretch the cover lengthwise. The roll is driven by a chain passing round a sprocket 41, and by removing the collar 39, the sleeve and parts carried by it may be drawn off the shaft 40 without disturbing the driving connection of the sprocket 41. Above the waxing roll and pressing against it is a metal roll 46, rotatably mounted on an eccentric portion 47 of a sleeve 48 which is rotatably mounted in a casing 49. The roll 46 may be raised out of or lowered into contact with the roll 5. The part of the casing 49 behind the roll 5 is covered by a detachable metal sheet 72, Fig. 2. The waxing roll and roll 46 may be heated by a hot oil circulating system, similar to that described in Specification 249,210, [Class 112, Sewing &c.]. Heated oil is passed up through a pipe 64, Fig. 5, to the casing 49, thence through a pipe 65, the sleeve 48, to a reservoir 66. From the reservoir a pipe 67 leads to the shaft 40, through which the oil passes by way of passage 69 and back by way of passage 70, and thence back to the heater. Oil circulation may be maintained by pump or thermo-synphonic action. The waxing roll 5 may be heated solely by the casing 49, if desired. The rolls 5 and 46 may also be heated electrically, as shown in Fig. 2, in which case heating cartridges 73, 74 are inserted in the sleeve 48 and casing 49. The polishing roll 6, a polishing roll 9 for burnishing that part of the waist of the sole which cannot be operated upon by the roll 6, and the brush 8 are fixed on the shaft 10. The brush 8 is partially enclosed in a metal hood 16. connected by piping to a fan to remove dust. The roll 6, of felt covered with stockinette, is partially enclosed by a hood 23 also connected to the fan, and also is provided with a heating device, e.g. a gas burner for warming the roll. The front portion 26, Fig. 3, of the hood is pivoted at 127, for swinging away from the roll when changing the cover. The rotary pad for burnishing the sole and breast of the heel is similar to that described in Specification 19085/10, [Class 60, Grinding or abrading &c.], except that it has a cloth cover such as a suedefinished fabric. The cover may be applied by a device of the kind described in Specification 255,549. [Class 60, Grinding or abrading &c.]. In a modification, the two polishing rolls are mounted on one shaft to the left of and axially in line with the waxing-roll. The brush, carried on a separate shaft, is behind and to the left of the polishing rolls, and the polishing pad is arranged between the polishing rolls and brush. Specification 208,794 also is referred to.
