408,279. Boot - making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Corporation ; 140, Federal Street, Boston, U.S.A.) Sept. 6, 1932, No. 24789. [Class 17 (i).] Sticking welt, or out-turned margin of upper, off last to sole margin by step-by-step pressing.- A machine for securing together a flange on a shoe upper and a sole by adhesive comprises a sole support and a flange pressing tool, means to feed the work past the tool so that it may operate on successive portions in step-wise manner, means for urging the flange against an edge gauge and into position to be engaged by the tool, means to prevent adhesion prior to pressing, and work clamping means operating after the pressing tool to press the parts more firmly together. Manual and power means are provided so that the work may be commenced manually and proceeded with by power. A sole support 20 is guided to move in a vertical path and is provided with rolls 34 co-operating with cams 36 linked to a treadle 48 for raising and lowering the support manually. A pressing tool 14 has a bevelled edge for engaging the crease between the upper and welt, an arcuate stem adjustable in a corresponding recess in a fixed bracket 12, and carries an adjustable edge gauge 18. The work is pressed toward the tool by a roll 52 at the end of an arm 53 clamped in a bolt 54 rotatable in a bearing at the end of a shaft 56 itself rotatable in a bearing in a frame 62 pivoted at 78. The shaft has an off-set arm 64 co-operating with an arm or a latch 68 to allow the roll to be swung laterally for work positioning. The frame 62 is oscillated with rise of the sole support by a stop 91 secured thereto and engaging a rod 85 over which is threaded a spring resiliently operating an arm 80 on the member 62. The arm 80 is returned by a spring 93. A separator blade 95 is pressed toward the sole support by plugs backed by springs 99, 101, and may be retracted when desired by a handle 98. For feeding the work, an upper jaw 102 is carried by a slideway 110 pivoted at 112 and a lower jaw 104 is carried by a slide 114 urged upwardly in the slideway by a spring 118. An arm 120 pivoted at 122 carries a pawl 123 co-operating with upwardly directed teeth on the slide 114 and a pawl 125 co-operating with downwardly directed teeth on the slideway 110. The arm is urged upwardly by a spring 127. An arm 124 on the slideway is pivoted to a link 126 reciprocated in the power operation of the machine. The arm 124 carries a stop 136 and the link 126 carries a stop 135, these stops co-operating with the arm 120 and the tails of the pawls, respectively. The effect of this mechanism is that the jaws are operated to clamp and feed the work, and, after each feeding movement, the jaws are opened and returned close to the tool before the lower jaw is allowed to rise and again clamp the work. After the work has been positioned and the treadle 48 depressed to clamp it, a treadle 150 is depressed to swing a detent 156 into engagement with a constantly reciprocating plunger 154. The detent is pivoted to the lower end of a plunger 131 carrying a cup 168 supporting a spring 166 engaging the flange 164 of a sleeve surrounding the reduced upper end of the plunger 131 and entering a bore in the lower end of the post 26 carrying the sole support. The upward stroke given to the sole support by the power mechanism can be varied by depression of the treadle 48. A shock absorbing collar 32 on the post 26 limits upward movement of the sole support. Specification 259,569, [Class 17 (i)], is referred to.
