Title: Improvements in or relating to Stop and Indicator Mechanism for Looms for Weaving, Warping Machines and the like.
Inventor: BAKER WILLIAM HENRY
Filed: 1903-06-08
Granted: 1904-06-08
Abstract: 12,900. Baker, W. H. June 8. Loom stop-motions; healds; warp tension, indicating; yarns, warping &c.-Relates to means for automatically stopping a loom, warping-machine, or the like, or for operating an indicating-mechanism therein, when a warp thread breaks or slackens. Each warp thread supports a " drop or detector " 1, which, when the thread slackens or breaks, falls upon a pair of notched bars F, f<2>. The bar f<2> is reciprocated longitudinally upon the bar F by means of an oscillating spring fork f &c. When the reciprocation of the bar f is not interrupted, "feeler pins" A3 are caused to pass through coincident apertures A<4> in the bars F, f<2>; but when the motion of the bar f<2> is blocked by a fuller " drop," the apertures A<4> in the two bars do not become coincident, the pins A<3> fail to pass through them, and a spring lever is operated for stopping the loom &c., or operating an indicator mechanism. More than one warp thread may be passed through the same " drop or detector." Various forms of " drops or detectors may be used, and they may be suspended on the warp threads either above or below the bars F, f<2>. The "drops or detectors" may be mounted in a frame and constitute the healds, as many bars F being used as there are heald frames, and all the " feeler pins " A<3> being caused to oscillate simultaneously. The bell-crank lever E, of which the spring fork f forms one arm, may be formed in two parts connected together by a pin e, so that they may be readily disconnected when the stop-motion is not required. The invention is applicable to looms for weaving pile fabrics or to looms in which some of the warp threads are made to weave or float loosely, these loose threads being supported by easing rods or bars which are adapted to take up excessive slackness in the threads. In this case, the notched bars F, f<2> are mounted and carried with the easing rods or bars. In cases in which the spring handle of a loom is provided with a stop or block for knocking-off, the stop is preferably hinged to the handle so that it may be turned out of operation when required.

Granted: 1904-08-18
Abstract: 22,466. Pfizenmayer, P. Oct. 17. Overlays and underlays.-Relief underlays are made of hard gutta-percha, insoluble gelatine, electrotype metal, or the like. The method employed may be that described for the preparation of overlays in Specification No. 19,850, A.D. 1899. The gutta-percha is enclosed between two sheets of hard paper, textile material, or the like, which is applied to the gutta-percha sheet by pressure and heat. The underlay is attached face downwards to the back of the printing-plate, in register with the design, by means of an adhesive such as fish glue. The plate and underlay are then subjected to pressure in a screw or other press, a piece of pressboard or the like being laid on the face of the plate to prevent injury to it. The plate is then backed with wood, metal, varnish, or the like. The reliefs used may be obtained by casting from a matrix obtained from a relief produced by photography, or any other means may be employed. An overlay for the tympan or cylinder and an underlay for the printing-plate can be taken from the same matrix or from two matrices of the same printing-plate. A matrix for casting overlays and underlays may be produced by taking an impression from the printing-plate in fusible metal, thin copper sheet, paste, cement, or the like, by pressure. Molten fusible metal may be poured on to the plate to obtain a matrix.
