Title: Improvements in and relating to shedding mechanism for looms
IPC: D03C19/00
Filed: 1932-04-25
Abstract: 380,750. Loom dobbies. STAUBLI, H., ST€UBLI, H., ST€UBLI, R., and ST€UBLI, H., (trading as ST€UBLI & CO., GEB.), Horgen, Zurich, Switzerland. April 25, 1932, No. 11888. Convention date, May 12, 1931. [Class 142 (i).] A crank-wheel dobby is controlled from an endless perforated band 1 of Verdol paper or like light material, means being provided for turning the cylinder 2 backwardly to find broken picks. Needles 11 adapted to pass through the perforations in the band are suspended on arms 9 of bell-crank levers loosely mounted on a common shaft, the other arms 10 being threaded on wires 15 guided at 16 and having eyes 17 receiving needles 18 suspended from a bar 20 above a vertically-reciprocated lifter bar 21 and beneath the vibrator levers 25. In the position shown, a cam-operated rod 13 supporting all the levers 9 has been lowered, thereby permitting the needle 11 shown to pass through the band 1, and the bell-crank lever 9, 10 to turn by gravity, so that the wire 15 draws the needle 18 into position to be engaged by a surface 22 on the bar 21. The vibrator 25 is thereby raised to bring the wheel 27 into engagement with the upper driving wheel 38 to change the shed through the mechanism 29 .. 32. The lifter bar 21 is then lowered, the bar 13 is raised to withdraw the needles from the band 1 and the cylinder 2 is turned to advance the pattern. When the bar 13 is raised, the bell-crank levers cause the needles 18 to be moved to the right by means of light springs 19 on the wires 15 arranged between the arms 10 of the levers and the needles 18. In a modification, the lifter bar is made so that it does not engage on its upward movement a needle 18 corresponding to a needle 11 which has passed through a hole in the card 1, the needles resting on the cards then determining the vibrators 25 to be lifted. In order to turn the cylinder 2 back to find broken picks, a pair of gears slidably mounted on the driving wheel shaft 41 is adapted to be slid into direct engagement with a wheel on a shaft 6 which drives the pattern cylinder 2 ; to drive the shaft 6 in a reverse direction through an intermediate wheel 46 ; or to be moved into a neutral position. The shaft 6 carries cams 23 for operating the lifter bar 21, and a cam 5 for turning one tooth at a time a wheel 4 on the cylinder 2, and for engaging a lever 36 for rocking the bar 13. When the bar 13 is raised when the cylinder is turned backwardly by hand, the pressure exerted by the springs 19 is not sufficient to move the needles 18 out of engagement with the lifter bar 21, the harness-controlling levers corresponding to the needles which are withdrawn from the band thereby remaining unaffected.
