Title: Improvements in or relating to drafting mechanisms for textile fibres
Inventor: NOGUERA JOSEPH
IPC: D01H5/56
Filed: 1952-01-30
Abstract: 715,534. Drafting mechanism. CASABLANCAS HIGH DRAFT CO., Ltd. Jan. 13, 1953 [Jan. 30, 1952], No. 2545/52. Class 120(2) In a drafting mechanism of the kind employing a number of drafting systems. arranged side by side each composed of consecutive roller pairs, the top rollers of adjoining systems being carried and weighted from the centre by an arm pivoted at the rear of the mechanism and incorporating a weighting saddle assembly which engages intermediate necks between the aforesaid top rollers, the front top rollers of adjoining systems are carried and weighted by a front saddle pivotally mounted on the arm in such manner that the said saddle and top rollers can be raised in relation to the arm by turning the saddle about its pivot against the weighting pressure, manually releasable catch means being provided for automatically retaining the saddle in its raised position on the arm. As shown, the front saddle 8 which is pivoted on a pin 11 has a finger piece 18 having a longitudinal slot 18a therein. Pivotally mounted on a pin 20 between cheeks 8b on the saddle upper part 8a is a hook-like catch .19. This catch 19 is influenced by a spring 21 such that its rear edge 19a is held against a transverse pin 22 mounted between the arm side plates 1, when the arm is in its normal working position. The catch rear edge 19a is provided with a hooked extension 19b at its upper end and a recess 19c at its lower end and there is a thin extension 23 to the catch 19 which can enter the slot 18a in the finger piece 18. To relieve the pressure on the front rollers all that is necessary is pull upwards on the finger piece 18. The rear edge 19a rides past the pin 22 until the recess 19c engages the pin, which engagement is brought about by the spring 21. The movement of the catch 19 brings the extension 23 out of the slot 18a above the finger piece 18 so that when it is desired to return the saddle 8 to the working position it is only necessary to lift on the finger piece 18 slightly and then depress the extension 23 into the slot 18a when the entire weighting arm is raised about its rear pivot the saddles are free to drop down slightly under their own weight but are prevented from completely falling away from the arm by engagement of the upper hooked end 19b of the catch 19 over the pin 22. With the arm in the raised position it is possible for the saddles to be disengaged from the arm by depressing the extension 23 through the slot 18a so as to free the hooked end 19b from the pin 22. Specifications 626,397 and 702,784 are referred to. Reference has been directed by the Comptroller to Specification 702,102.
