Abstract: 5831. Pride, J. P., Bates, A., and British United Shoe Machinery Co. March 20. Soles ; channelling ; burnishing; uppers.-Relates to a machine which, besides laying the channel flap, simultaneously bends the sole margin to or beyond its original plane, so that it is moulded to the same extent as the remainder of the sole when the latter is subjected to the levelling operation. The devices for effecting this comprise a rotary tool D which engages the tread side of the sole margin, and a vibratory tool E which engages the upper side of the margin, as shown in Fig. 4. The tool D is mounted at the upper end of a shaft F journaled so that it can move endways in a swinging frame G pivoted upon, or concentric with, the main shaft B of the machine. The frame is normally held in its forward position by an adjustable spring H, but it can be moved, to separate the tools D, E, by depression of a treadle. In order that the tool D may act yieldingly on the work, the shaft F is surrounded by a spring L, which is normally in slight compression between two adjustable sleeves G<3>, G<6> screwed into the frame G, the upper end of the spring bearing directly against the sleeve G<3>, while its lower end rests upon the upper G<4> of two loose collars G<4>, G<5>, the lower of which bears against the sleeve G<6>. An antifriction device M is placed between these two collars. When the work is placed in the machine, the shaft F is raised, and a boss F<1> on it comes into contact with the collar G<5> and causes the spring L to be compressed further. The shaft F is driven by worm-gearing from the main shaft B, which arrangement ensures that the two shafts will always remain in gear irrespective of the position of the frame G. The tool E is mounted in a carrier E<1>, which can slide in a curved guideway A<2> formed upon or secured to the frame A. Projecting downwards through a slot in this guideway is a pin N<5> depending from a sleeve N<3>, which is mounted on a slanting, eccentric portion N<2> at the front end of a rotating shaft N. The parts N, N<3>, N<5> are so disposed that the pin W<5> receives a vibratory as well as an oscillatory movement about its axis ; in order, however, that the former movement only will be imparted to the member E, the pin is passed through a slot in a roller E<2> loosely mounted in the carrier E'. The tool E has a thin wedgeshaped part E<3>, Fig. 6, which engages the feather of the boot, and a spring-pressed block E', which engages the upper and causes it to conform to the shape of the last. The member D consists of three segments D', Fig. 7, pivoted upon pins D<2>, and pressed outwards by springs D<3>. Each segment is acted upon by two springs, and the movement of each is limited by the engagement of slots D' with the pin of the adjacent segment. They are each provided with diagonal ribs D<5>, which, besides closing the channel, serve also to feed the shoe along. In addition, the member D is provided with a projection D<6>, which acts as an edge gauge for the sole, as shown in Fig. 4. The machine can also be used for forcing the sole margin out of its original plane before the channel has been opened. This may be effected by either of the members D, E being dispensed with and a fixed abutment being used in its place. The member E may also be replaced by an angular, spring-controlled feedwheel. The member D may also be provided with a spring and side cam, to cause it to move in the line of its shaft. It may also be arranged so that the ribs D<5> tend to screw the work in the direction in which it is to be fed. A number of rests such as D<6> may be provided, and each may be vibrated to hammer the edge of the sole and so to assist in closing the channel. The machine may also be used merely as a channel-flap laying-machine.
