Title: Improvements in machines for the treatment of skins and leather
IPC: C14B1/40
Filed: 1921-07-01
Abstract: 166,126. Mercier, D. July 8, 1920, [Convention date]. Endless-band tool machines.- The hide is worked between upper and lower bands brought into contact over portions of their length moving in the same direction, one band being provided with working blades and the other with pneumatic cushions, the bands being pressed into engagement by rollers arranged in staggered relation so that the engagement is flexible throughout. In the form shown in Fig. 1, the lower bladed band 2 travels over a driving roller 5, tensioning roller 7, an end roller 6 enclosed by a cover 13 and fixed bed rollers 14, 15, 16. 'The upper band 23, provided at intervals with pneumatic cushions 24, passes over fixed rollers 17, 18, 19 and under rollers 20, 21, 22 carried by pivoted links 50 connected by a link 51 whereby the band can be raised or lowered. Power is transmitted from a shaft carrying fast and loose pulleys and a gear-wheel 8 which drives the lower band 2 through a gear 9 on the pulley shaft 5, and the upper band 23 through an idler 8<a> and a gear 32 on the roller shaft 19. From the roller shaft 5 a belt rotates a cam 29 actuating a lever 27 operating the link 51 through a connecting-rod 26, the pivoted framework 50, 51 being swung up at intervals to allow of insertion or removal &c. of a hide. When in position, the end of the hide lies over and is pressed against the cover 13 by the body of the operator, the bands drawing upon the hide to stretch it and to render it flexible. The swing- ing movement of the links 50 is rendered adjustable by connecting the lever 27 to its pivot 52 by a slot 34, the lever being supported by a lug 35 engaged by the forked extension of a lever 36 in a quadrant 37. In a modification shown in Fig. 3, the upper band is carried on fixed and adjustable rollers on an arm 56 pivoted at 57 with an extension 56<a> counterweighted at 58 and connected to a vertically-slidable rod 27<a> with a bowl 28 resting on a rotary cam 29, the arm 56 being raised and lowered by the action of the cam. The pressure is regulated by a roller 44 mounted on a lever 12a. The pneumatic cushions on the upper band may comprise balls of the tennis-ball type in a flexible mounting of felt, leather, &c., enclosed by a leather covering and secured to the band by nails or fasteners. Instead of the cam operation, a hand or footlever may be provided to control the position of the upper band.

Abstract: 1,163,862. Sewing machines. SINGER CO. 20 April, 1967 [25 April, 1966], No. 18128/67. Heading DIG. A lock stitch machine comprises a rotary looptaker body having a needle thread loopseizing beak, a bobbin case journalled relatively to the looptaker body, means for restraining the bobbin case from circular movement with the looptaker body, and means for shifting said restraining means from a first to a second position, whereby, when the bobbin case is in said first position needle thread loops are carried completely therearound, and when the bobbin case is in said second position the needle thread loops serve to replenish thread on a bobbin journalled in the bobbin case. A shuttle 22 is journalled in a raceway formed in a fixed housing 20, and is held in position by a retainer 23 capable of limited angular movement about studs 24, 25 projecting from housing 20 through arcuate slots 26, 27. The shuttle is rotated by a driver 52 located in a notch 51, one side of which is formed as a loop-siezing beak 54. A bobbin case 33 is journalled on a post projecting from the shuttle and is secured thereto by a screw 32. Thread from a bobbin, journalled within the bobbin case, leaves the latter by a radial slot 40 and is tensioned by a leaf spring 41 secured at 42 to the bobbin case. A finger 34 extends from the latter between abutments 35, 36 on retainer 23. For stitch formation, a tongue 105, engaging a slot 106 in retainer 23, shifts the latter to the end position shown, when slot 40 is positioned above the point of tangential engagement of the seized loop with the bobbin case. For bobbin replenishment, the limb of the seized loop extending to the work is clamped to the shuttle adjacent beak 54, and tongue 105 is simultaneously moved clockwise to shift retainer 23 to its other end position. Slot 40 is then positioned at said point of tangential engagement, and successive seized thread limbs extending to the needle 18 thereby pass through slot 40 and are wound on the bobbin.
