Title: Improvements in and relating to soles and other articles and the method of preparingthe same for sewing
IPC: A43D8/02
Filed: 1918-05-01
Abstract: 137,343. Marks, E. C. R., (Blake Inc., C. C.). May 1, 1918. Stitches and seams; sewing-machines; stitching by locking thread loops with tongues of leather.- Stitch-anchoring tongues are produced in a member, such as a shoe sole, by slashing the face of the member partially to form the tongues and cutting through its edge substantially parallel to the slashed face to intersect the slashes around the outlines of the tongues. A member so formed is secured to one or other members by providing this member, or the outer of such members', with a split along its outer edge and passing a thread or wire &c. through the elements and anchoring it on the tongues and within the base of the split. The invention is described particularly in connexion with the treatment of insoles and the method of securing together the welt, upper, and insole of a shoe. A series of furcular slashes A, B, or C, Fig. 1, are formed normal to one face of an insole 1 and are intersected by a series of awlcuts 6, Fig. 6, extending from the edge of the insole to the slashes to form tongues 7, which receive the loops of the inseam stitches. In one construction of shoe an upper 8 is up-drawn and cemented to the edge of the insole, and is assembled with a welt 9 provided with a longitudinal slit 11, which is located in the same plane as the bottoms of the tongues 7. A thread is then passed through the slit 11, welt, upper, and insole, over the tongue 7, and back through the insole, upper, and welt to the slit 11. Preferably, the slash shown at C, Fig. 1, is employed, and this is formed by a gouge 12, Fig. 3, provided in the sewing-machine, to which the assembled shoe is presented after lasting; the gouge carries a stop 15 to limit and unify the depths of the slashes. In the operation of the machine, after the gouge is withdrawn, an awl, which is slightly wider than the distance between the tines of the forked part of the slash, is passed through the welt, upper, and insole in the plane of the slit 11 to form a tongue 7. As soon as the awl is withdrawn, a straight, eye-pointed needle 17, Fig. 0, carrying a thread 10, passes through the passage made by the awl, and the thread is engaged by an oscillating looper 19, which throws a loop of thread over the tongue 7 and then, after releasing the loop, wipes the tongue down flush with the face of the insole, Fig. 11. Fig. 12 shows a section of the shoe with the welt and bottom Face of the insole in the same plane, thus avoiding the necessity of employing filling-material in the completion of the shoe.

Abstract: 902,183. Control devices for moulding machines. TOS RAKOVNIK NARODNI PODNIK. March 2, 1960 [March 4, 1959], No. 7328/60. Class 78 (1). A moulding 1, which has just been ejected from a moulding press (not shown), falls down shoot 2 and is checked by sliding gate 5 so as to lie in a position between jaws 3, 4. As a consequence of the press cycle, electromagnet 6 is energized to cause jaw 3 to descend towards jaw 4. Jaw 3 engages the moulding, and the moulding engages jaw 4; and together they descend as a unit to cause contacts 8, 9 to close. This commences the next cycle of the press, whereupon jaw 3 rises, gate 5 is lowered, the moulding is discharged from the bottom of the shoot, and the press ejects the next moulding. If, however, a moulding has not been ejected from the press, then when jaw 3 descends the jaw 4 will remain stationary and the contacts 8, 9 will remain open. The press will then remain inactive to allow removal of the unejected moulding.
