Title: Improvements in or relating to machines for channelling boot or shoe soles
IPC: A43D43/02
Filed: 1928-06-01
Abstract: 322,198. British United Shoe Machinery Co., Ltd., and Bates, A. June 1, 1928. Stationary - cutter machines. - A machine for cutting in a sole a channel, the entrant position of which varies at different parts of the sole, comprises a knife 31 adapted to cut a curved channel of the English type entering from the face of the sole A and a second knife 51 adapted to cut a channel of the American type entering from the edge of the sole. Knife 31 is mounted on an arcuate slide 29 moving in an arcuate guide 27 on a block 25 on a stem 21 adjustable in a slideway in the top arm of the machine, while top-arm carries the presser roll 15 on a shaft geared to another shaft 3 carrying the feed wheel 5. Knife 51 is carried by a slide 55 which moves in a guide 53 in the arcuate slide 29, a lug 57 on the slide 55 being connected by a link 59 to an arm 61 on a rock shaft 37. The latter carries a toothed sector 35 gearing with teeth 33 on the arcuate slide 29. With the parts in the position shown in Fig. 1, the cutter 31 is in line with the cutter 51 and drawn back so that an American-type channel is cut; by rocking the shaft 37 the cutter 51 is withdrawn and the cutter 31 moved to the position shown in Fig. 2, so that an English-type channel is cut. Thus, in a continuous operation one side of the waist of the sole may be American channelled, the forepart of the sole English channelled, and the other side of the waist American channelled. The shaft 37 may be rocked by means of an arm 39 and treadle rod 41 or by means of a cam wheel normally free on the presser-roll shaft but adapted to be clutched thereto by the operator, so that at a particular time movement of the cam is transferred to the rocker and the channelling knives are moved gradually from one position to the other at a rate proportional to the work feed, so that the one type of channel runs smoothly into the other. The bottom of the channel may be grooved by fitting a grooving knife in a recess in the shank of the channelling knife, and the channelling operation may be assisted by providing means for oscillating the knife or knives in the line of feed. A single knife may be used to effect the two kinds of channelling, the knife being intermediate in shape between the two usual kinds of knives and mounted in an arcuate slide so as to be movable to the two requisite operative positions. In the modification shown in Fig. 6, both channels are made by a straight knife 251; when making the English channel a second presser roll 216 is brought into operation shaped to deform the edge of the sole against an auxiliary work support 206. Specifications 315,812 and 322,451 are referred to.

Abstract: 939,649. Corrugating. JAMES BURN & CO. Ltd. May 1, 1962 [May 3, 1961], No. 16688/62. Class 83 (4). A wire forming machine comprises two opposed sets of die blades which are continuously movable in such a way that the blades of one set mesh with those of the other during a portion of their travel so as to form wire passing between the blades into a series of bends, alternate bends having the shape of the blades of one set, and two rotatable die rolls each having a helical groove the pitch of which diminishes in the direction of movement of the wire, each groove being arranged to receive alternate apices of the bends of the wire formed by the die blades and to more closely form the bends to a desired shape. Wire 11 fed through a guide 12 passes between intermeshing blunt blades 15 and sharper blades 16, carried by opposed endless chains 13, 14 which form the wire into zigzag shape. The bent wire then passes between die rolls 19, 20 having helical grooves 21, 22 to engage the apices of the bends in the wire. The grooves decrease in width and pitch towards the ends of the rolls in the direction of travel of the wire so as to squeeze the bends into parallel finger shape. The groove 21 in the roll 19 is narrower and decreases in width more rapidly than the groove in the roll 20. Die members 25, 26 at the end of the groove 21 on the roll 19 pinch the tips of the bent wire to the form 23, Fig. 5, and die members 27, 28 on the roll 20 at the end of the groove 22 give a set shape 24 to the opposite wire tips.
