Abstract: 26,551. Boult, A. J., [United Shoe Machinery Co.]. Nov. 23. Cementing.-Relates to a cementing or other coating machine adapted for use with cementapplying members of varying sizes. The invention is described as a machine for cementing the channel-flaps and soles of boots and shoes. A cement-applying brush 14 is mounted on a rotating shaft 16 which may be driven through a clutch 20, and is supplied with cement from a reservoir 10 by way of a conduit 12. The flow of cement through the conduit is adjusted or arrested by a plunger actuated by a handlever 38 or by a stop-cock. The brush 14 is composed preferably of a series of bristles 15, Fig. 5, secured in an annulus 48 of wood &c. mounted on a hub 50, which is clamped in position on the reduced end of the driving-shaft 16 between flanges 52, 54 by a locking screw 60. In cases in which the annulus 48 is made of wood or material liable to warp, the size of the hub 50 is such as to afford sufficient clearance between the annulus and the locking-flanges 52, 54, as shown in Fig. 5. Modifications are described in which the hub is replaced by a sleeve formed integrally with one or both of the flanges 52, 54. In the latter case, the sleeves 522, 542, Fig. 10, are in screw-threaded engagement, and may be screwed into contact with the annulus 48 when the latter is of moistureproof material not liable to warp. The top of the brush 14 and the flanges 52, 54 are preferably enclosed in a hood, comprising a peripheral cover 67 integral with a side plate 68 and a side plate 69 adjustably secured in the cover 67. The opening through which the cement is delivered to the brush is so arranged that the flow of cement is substantially radial to the axis of the brush, or tangential to its periphery, and in a direction opposed to its rotation so that any surplus cement becomes automatically banked up in the conduit outlet. The cover 67 of the hood is recessed in the vicinity of this outlet and serves to hold a reserve body of cement in contact with the brush. To prevent flooding of the apparatus as the brush wears down, adjustable scrapers penetrate the hood 67 and engage the periphery of the brush to force back into the supply passage any surplus cement carried by the brush or otherwise. In cementing channels and channel-flaps, a work-guide and channel-flap raising-device is preferably employed, comprising a member 105, Fig. 4, which engages the work and is pivoted to a carrier member 100, adjustably secured by a bolt 102 to the slide plate 69 of the hood. This guide 105 is maintained normally in a depressed position by a spring 109. In conjunction with this guide, or in substitution thereof, an edge gauge may be used comprising a flanged wheel adjustably secured to the framework of the machine. A removable strainer 120, supported on cross-bars 122 in the reservoir 10, is preferably provided to arrest foreign matter in the cement. The side plates of the hood may be flared outwardly at their lower ends, and serve as means for wiping back on to the rotating brush any cement that may be carried round on the bevel portions of the flanges.
