Abstract: 858,506. Optical scale reading apparatus. NEWALL ENGINEERING CO. Ltd., and OPTICAL MEASURING TOOLS Ltd. Oct. 8, 1957 [Oct. 8, 1956], No. 30648/56. Class 97(1) [Also in Group XXII] A machine-tool such as a jig-boring machine is provided with optical means for indicating the position of one or more slide members which includes separate optical projection means for a scale carried by the slide and for numerals on a numeral-bearing member driven by the slide through a disengageable clutch. The machine is of the type with a vertical pillar 12, Fig. 2, for a tool-head and a slide 18 supported on a knee 11. A work-table 21 is provided movable at right angles to the slide 18 and supported thereon. Optical indicators are provided for both the slide 18 and the table, but the former only will be described. The slide 18 carries an engraved scale 26 which is without numerals and has divisions 1/20 inch apart. This scale is illuminated by a lamp 30 and condenser 31, Figs. 2 and 8, the light beam passes from the condenser on to the scale and the image is picked up on the half-silvered concave surface 34a of an objective lens 35a and reflected on to prism 36. The latter is cut away to allow the light beam to reach the scale. The light reflected by the objective 34a falls upon the silvered face of the mirror 36 and is reflected downwardly on to a further reflector 37 through magnifying lens 38 and by mirror 39 to an optical micrometer 40, Figs. 2 and 10. This includes two wedge-shaped prisms which are adjustable laterally relative to the light beam and is described in Specification 652,927. The beam finally passes from the optical micrometer through a projection lens 42 and a system of mirrors 43-46 to a screen 47, Fig. 2, provided on a control console 22 at the operating position of the machine. The optical micrometer 40, Fig. 10, is provided with a fine scale 148, a scale 151 in the form of a series of black blocks and a fiducial mark 150. Adjustment means is provided for zero-setting and the general purpose of the micrometer is to enable the scale divisions, which are magnified 50 to 1, to be accurately subdivided on the screen. A continuous steel wire anchored to the slide 18 is wound around a drum 51, Fig. 4. The drum may be clutched by a screw knob 59 to rotate a disc 68 which carries a circular glass scale 70 on which is photographically reproduced a a circle of numerals corresponding to the divisions of scale 26 on the slide. The image of these figures is transferred by a separate optical system to screen 47 alongside the image of the markings of scale 26. The spindle 67 which carries the disc 68 projects out of the console and markings on a knob 75 on the spindle give a rough indication of the position of the slide while it is moving.

Title: Improvements in yarn feeding means for knitting machines
IPC: D04B15/38
Filed: 1936-11-10
Abstract: 484,711. Knitting. SOC. ETABLISSEMENTS LEBOCEY. Nov. 10, 1936, No. 30694. Convention date, Nov. 20, 1935. [Class 74 (ii)] A yarn feed device, particularly for use with elastic yarns and having means actuated from the machine for intermittently moving a yarn guiding eyelet which changes the position of the yarn along conical drums is characterized in that the eyelet is traversed by a simple or composite cam. The yarn can be fed at a variable rate or tension between cones 1, 2 of which the cone 2 is loosely mounted on its spindle, whilst the cone 1 is fixed to the driving spindle 3. The spindle 3 is driven through a change speed gear consisting of conical pulleys 4, 5, connected by an endless belt 6, the position of which can be varied by means of a screw 8 to vary the speed of the feed cones 1, 2 ; cone 5 is driven from the machine through wheel 10 and pinion 9. The yarn 13 passes through an eye 11 carried on a sliding rod 12 controlled by a scroll cam 14 which is driven by worm and worm-wheel 16, 15, the worm being rotated by means of a star wheel 17 and sliding tappet 19 carried by a rotary crown wheel rigid with the knitting machine. The tappet can be moved to an inactive position 20 and thus the feeding rate of the yarn made constant. The drop a, b on the cam permits a quick return of the yarn guide to its original position after a revolution of the cam during the fashioning of an article. Fig. 4 (not shown) depicts a somewhat differently shaped cam rotated by a ratchet wheel which is actuated by a link and crank device. The surfaces of the cones 1, 2, may be striated, fluted, milled, or covered, to provide a grip on the yarn. The scroll cam may be replaced by a chain, a drum provided with driving cams, a ratchet actuated screw, a linear cam, a stepped cam or other mechanical equivalent. The change speed gearway consist of stepped pulleys, friction plates, gears, etc. The device is primarily intended for the feeding of elastic yarn, but may be used, in combination or not with automatic sinker cam control, in fashioning by variation of the stitch length. Patterning can be incorporated in the case of an elastic yarn held between the plain and rib loops of a rib knitted fabric, by the use of a Jacquard the elastic yarn being made to appear at certain places only ; differently coloured stitches may also be made to appear on the ground fabric.
