Abstract: 15,292. Gouldbourn, J., and British United Shoe Machinery Co. July 25. Heels.-Relates to a heel-breasting machine adapted to cut breasts to various contours by relatively traversing the heel and the cutter, without the employment of interchangeable guide templets or cams. In one form of the invention, Figs. 1 and 2, a rotary cutter is mounted in fixed bearings, and the heel is secured on a movable plate, but in an alternative construction, Fig. 6, the heel may be stationary and the cutter mounted in bearings supported upon a movable plate. Referring to Figs. 1 and 2, the heel K is clamped to a cariier G by a clamp H operated by a handle H<10> and cam H<7>, which clamp also secures the carrier G adjustably in a controlling-plate F. The controlling-plate F can be moved by its handle F<4> in a path determined by cam-slots F<2> and rollers mounted on studs E', E<2>, The studs are carried by a slide E adjustably secured by a clamp D' in an arm D, which is pivoted at C<1> to the frame of the machine and clamped in adjusted position by a lever C'. The cutter A is mounted on a shaft journaled in the frame and rotated by any usual means. In operation, the action of the cam-grooves and rollers so guides the plate F that the heel moves in a curved path past the cutter, slightly rocking relatively to the cutter, and is trimmed thereby to a curvature different from that of the acting face of the cutter. By setting the heel carrier G nearer to the grooves F', the breast is trimmed to a curve more nearly approaching a straight line, and, as this operation may move the heel too far within the range of the cutter, means are provided for adjusting the plate F and carrier G together forwardly in the machine. The arm D has an extension D<2> formed with rack teeth adapted to be engaged by a pinion F<5> mounted on a shaft F<6> in the plate F and provided with an operating- handle F<7>. An intermediate pinion F<8> on a second shaft F<9> on the plate F gears with a second pinion F<10> on the shaft F<6> and also meshes with a rack-bar G<3> on the carrier G. To adjust the parts, the carrier G is unclamped from the plate F, and the slide E from the arm D, the handle F<7> is then turned to move the carrier G towards the camgrooves F<2>, and the carrier G, plate F, and slide E together towards the front of the machine, and, finally, the carrier and slide are reclamped in their new positions. Referring now to Fig. 6, a heel carrier G <x> is mounted directly on the machine frame B, and a rotary cutter A<x> is carried by a controlling-plate provided with a handle F<4x>, by means of which it may be moved past the heel Kx. The path of the cutter is determined by cam-grooves F'x, F'x and rollers mounted upon studs E'x, E<2x>. To retain the controlling-plate in position on the frame, it has three lugs F<11> which engage overhanging flanges B<3> on the frame. To provide for various breast curvatures, the cuttersupporting slide A<2> and heel carrier Gx may be adjusted in the plate Fx and frame respectively, by hand-screws D<3>x, G<3X>. The form of the camslots may be varied.
