Specification of Letters Patent.
Application filed December 4, 1912. Serial No. 734,861.
To all whom it may concern: 1 I
Be it known that I, PAUL TURLUR, citizen of the French Republic, residing at lVattrelos, in the Department of Nord, France, have invented a certain new and useful Improved Arrangement for Dobby and Jacquard Mechanisms Weaving with Open Shed, of which the following is a specification.
This invention relates to improvements in dobby and jacquard mechanisms which are especially adapted for weaving with open shed.
In my application, Serial No. 625,094, filed May 4, 1911, I have shown and described a form of mechanism adapted to control the movements of the movable jack which is adapted to be connected to the harness of a heddle frame, and the present invention relates to improvements in the mechanism for raising and lowering the jack as well as looking it in its raised or lowered position, which mechanism is of a simple and compact construction and capable of locking the'jack in its raised or lowered position without the use of the extra bolts, pawls and other parts which have been heretofore used for this purpose.
With this and other objects in View, which will be apparent from the description, my I manner. Projecting laterally from the jack 1 adjacent its lower end is a lug 3 carrying a pivot 1 upon which a T-shaped member 5 is mounted, which is provided with teeth 6 and 7 at the ends of its lateral arms. A jack-hook 9 is pivotally connected to the member 5, as at 8, and has an oscillatory lateral movement as well as a vertical move ment, its upper end being normally urged toward the right by the compresslon spring 10. A locking lever 11 is provided at its upper end with spaced notches 13 and 1 1 whlch are respectively adapted to co-act wlth the teeth 6 and 7 to hold the jack 1 in either its raised or lowered position, the upper end of the locking lever being normally urged against the teeth 6 and 7 by means of the spring 12. The jack-hook 9 is raised or lowered by means of any of the well known constructions used in looms for this purpose and in the specific embodiment of the invention shown, a disk 15, which is. provided with arms mounted parallel to the axis of rotation of the disk and adjacent the periphery of the same, is rotated continuously in such a manner that the arms act as eccentric bars andv serve to lower the jack 1 when the jack-hook 9 is engaged, the j ack-hook being provided with a laterally projecting hooked portion 18 which is normally thrown into the path of one of the arms 15 by means of the spring 10. In the same manner the jack is raised by means of the second disk 16 provided with Patented July 7 1914.
similarly mounted arms, which is driven in j I the same direction as the disk 15, as is clear from'the arrows designating the rotation of these two disks. The movable jack-hook 9 has projecting laterally from its extreme upper end a second hook 19 which is adapted to be engaged by the arms carried by the disk 16. L
17 designates the needle of the jacquard mechanism which enters the perforations in the ordinary form of card (not shown), which needle serves to press the movable jack-hook 9 against the action of the spring 10 toward the left, so that the hook 19 will engage the arm 16 when the end of the needle 17 is pressed backwardly, which occurs when it meets a solid portion of the card (not shown).
Mode of operation :-The position of the parts of the mechanism illustrated in the drawing shows the instant at which needle 17 has entered a perforation of the card. By dint of the action of spring 10 the movable part or head 9 places itself in the course of disk 15 and one of the arms or bars of this disk will strike against projection 18 provided for this purpose, so that head 9 is first lowered with regard to stave 1, whereupon part 5 is shifted accordingly and removes tooth 6 from notch 13 of the look ing device so that the whole of the hook is liberated. The latter will then owing to newperforations will'againcanse needle 17 Q N c 2, 2
the continued action of disk be loweredo and will cause the hecldle to be raised which 'it controls.
When it has arriveda't the end of its path projection 18 of thehead will;
.be liberated owing to the rotation of the; arm on'its'axis, while the whole hook de-; vice is supported in its new position by the; engagement'of tooth 7 beneath notch 14 of the locking lever. As long as the perfora tions in the cards correspond with the nee die 17 vof thi's'hook, the position of the latter will benlaihtained and the shed -will thus he kept open. As soon'as the needle 17 harness of a heddle-trame, a member PIVOT/7 no longermeets with a erforation, it is repelled andbears against the movable head 9, so thatjthe latter is =pu'shed back 'and another iorojeotion 19' proy ided in thesa'i ne for this purpose 'plaoesjitseli' in 'the path of the arm of disk 16. At this moment the head 9 W'iIl be raised, part'sis shifted and repelsjb'y tooth 6; the looking lever 11 which freestooth 'Z, so that the whole contriy'a'n'ce is unlocked and removed with diskllGas the latter continues itsr tation. Atthe end of -its coarse projection 19 oil the head 9 will be liberated owing to the rotation of the arm of the "disk, while" tooth on ages in notch 13 of looking lever 11,so that the hook will "be locked in this position iniitil tobe: shifted, V What I claim is 2 I Q ilJIn a-dobby' ""echanism for looms, a movable jack hd'aptedto b'e conne c'tedto the any oonnecte'cl to said a ck, 'a locking lever having interengaging parts for lockingthe jack in either its raised or lowered position,
