Abstract: 20,801. Northampton Machinery Co., Collier, J. V., and Edwards, A. W. Sept. 12. Insoles, machines for. -A reinforcing-strip of canvas or like material is applied to an insole in such a manner that it extends over the lip on each side, and also extends for a short distance over the insole on one or both sides of the lip. The roll of strip or tape material c, which is coated with rubber solution, is drawn from a carrier 31 over a pulley 33 heated by a burner 34 for the purpose of melting the solution. Two pivoted arms 35, having guides 36 for the strip, are connected with the starting-treadle of the machine, and, when the treadle is released, take up such a position that the strip is lifted from the heated roller. The strip passes from the pulley 33 into a heated guide-device 40, which is adapted to shape the strip to enable it to fit over the lip of the insole. The channel of the guide-device 40 gradually narrows from its upper end, and is provided with a groove gradually increasing towards the lower end. A cover 42 over the channel is formed with a corresponding ridge for the purpose of pressing the strip into the groove. The guide 40 is movable about a vertical pivot 44 to enable it to follow the shape of the insole as this passes through the machine. The guide may be lifted vertically, to enable the strip to be cut, by depressing a lever 47, to which the pivot 44 is connected. The strip is drawn through the guide by gripper and presser members 19, Fig. 3, which also feed the work. These members are arranged to be closed on the work by cam - slots 20 in a slide 21 operated through a spring connexion 23 from an eccentric 15. In a modification, the members 19 may be closed by a wedge and opened by a spring. During the time the members 19 are pressing the strip against the lip and the insole, the insole is supported by a foot-rest 24 pivoted to a frame 12 and resiliently supported by a spring 26. The feeding movement of the members 19 is given by a swinging movement of the frame 12 on which they are carried. The frame is hung from a pivot 11 on the machine frame, and is given its swinging movement by a crank-pin 13 on the cam-shaft 3. To enable the strip to fit neatly around the toe portion of the insole, a knife 52, Fig. 2, is provided in close proximity to the members 19 for the purpose of nicking one or both sides of the strip. The knife is attached to a rod 53 carried in bearings on the frame 12 and normally held raised, so that the knife clears the strip/by a spring 55. A collar having a projection 58 is mounted on the rod, and can be turned by a handle 56 so that the projection 58 comes below a projection 59 on the slide 21, thus depressing the knife and nicking the strip. After an insole has been reinforced, the strip is cut through by shears 60, 61, Fig. 2, the blade 60 being fixed and the blade 61 movably attached to the front end of a slide normally retained in its rear position by a spring, but forwardly movable by a hand-lever 64. The forward movement of the slide also causes the moving knife to be closed upon the stationary one for the purpose of severing the strip.
