Abstract: 638,598. Draughting-machines. BRAKENHIELM, C. A. B. R. Dec. 30, 1947, No. 34611. Convention date, Feb. 24, 1942. [Class 97 (iii)] A drawing board 2 having a T-square 3 guided in parallel manner by means of flexible cords or the like is characterised in that the cord 1 is endless and in the form of a figure of eight and is guided through or over guide members 4, 5 at the corners of the board, and over members 6 at the ends of the T-square, the cord being crossed on one face of the square so as to form one loop above and another below the square, the arrangement being such that the T-square may be swung in the plane of the board by displacing one loop of the cord whilst the other loop is held against displacement. Subsequently by freeing the other loop the square may be moved parallel to its swung position. As shown, the lower loop of the cord passes through guide members 5 in a member 7 secured to the lower edge of the board 2 and may be locked against displacement by a screw 12. Alternatively, the lower loop may pass through holes through the board arranged in a similar manner to the holes 4 for the upper loop. The holes 4 and 5 are preferably sleeved with friction - producing material so as to subject the cord to greater friction than the guide-rollers 6 secured to the T-square. An indicating device 9 may be secured to the upper loop of the cord so as to indicate on a scale 10 the extent of angular movement of the T-square. The scale 10 may be provided on a polygonal ruler rotatably mounted along the top edge of the board 2, each face of the ruler presenting a different scale to the indicator pointer. A similar scale and indicator may additionally be provided for the lower loop of the cord.

Nov. 22, 1930, Nos. 35207/30 and 7476/31. [Class 142 (iii).] Bobbins, pins, tubes and the like are automatically transferred from a magazine to the loom shuttle by mechanism that is set in operation only as a result of simultaneous movement of a shuttle actuated member and the weft feeler mechanism. A casting A, Fig. 1, pivotally mounted on a stud a on the lay or the shuttle box, is connected by an adjustable link a4 to the crank arm a<5> of a lever that is pivoted on an upright stud a<6> and is formed with a cam portion a<7> that projects into the shuttle box. When a shuttle enters the box it engages the cam portion a<7> and imparts a turning movement to the plate A thereby bringing a notch as thereon into position to be engaged by the chisel-shaped edge c, Fig. 6, of a member associated with the weft feeler and transfer mechanism, the movement of the plate A being limited by a fixed stud a<2>. A shaft D mounted in the magazine frame carries the usual transfer hammer G and an arm c<2>, the latter providing pivotal support for the two-armed lever C, one arm of which is kept in contact with an arm h<9>, on the weft feeler rod h<7>, by means of a spring h<10>. Weft feeler arrangements. A slidably mounted weft engaging member H, held in a forward position by a spring h, is arranged on weft exhaustion to engage an arm h<1> of a lever, pivoted at h2, and cause the other end h<3> to press a finger h<4> into engagement with the weft hammer whereupon the rod h<7> is rocked. The movement of the rod h<7> causes the member C to pivot about the stud c<1> thereby bringing its edge c into a position in which it will engage the plate A, if such has been moved by a correctly positioned shuttle, and operate the transfer hammer G. If the shuttle has not been properly boxed the end c passes on one side of the plate A and no change takes place. To provide more room for the cop change mechanism the picker K and its attendant parts are mounted at the back of the shuttle box.
