Filed: 1924-12-31
Abstract: 230,418. Sulzer FrÞres Soc. Anon. March 5, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Releasing-gears.-The admission of steam to the cylinder is controlled partly by throttling the supply and partly by varying the cut-off. Under heavy loads the control is effected by varying the cut-off; under light loads the control is effected by throttling with or without a cutoff control. In the construction shown, the catch i of the releasing-gear is actuated by an eccentric through levers q, r and links p, n. The lever q is pivoted on a lever t pivoted at s which lever is controlled by a governor e through an arm u which is also connected up to a throttle valve y through a slotted link z to operate it at light loads. The governor link r may have a slotted engagement with the lever t so as to become inoperative at light loads.

Filed: 1927-11-23
Abstract: 295,532. Triumph Cycle Co., Ltd., and Sykes, A. A. Nov. 23, 1927. Tension arrangements. - In chain tensioning- means, particularly for chains engaging sprockets on the crank shaft, cam shaft, and magnetic armature spindle of internal combustion engines, the tensioning-sprocket 5 is carried loosely on a crankpin 6 on a spring-biased rock-shaft 7, which carries with some lost motion a ratchet wheel 17 engaged by a stationary pawl 21. The spring 12, of clock-spring form attached to the framing 14 and to the disc 10 integral with the shaft 7, together with ratchet device effect automatic tightening of the chain when necessary, and the lost-motion means, comprising a lug on the wheel 17 engaging a slot in the disc 10, prevents shock by allowing limited reversal of the tensioning movement of the sprocket 5 during back-firing &c., the spring 12 cushioning such reversal. Endwise movement of the shaft 7 is prevented, and rotary motion is limited, by the use of a pin or screw 24 in the framing engaging a groove 23 extending partly around the shaft.

Title: Improvements in and relating to the steaming and smoothing of fabric webs
IPC: D06C7/00
Filed: 1933-11-18
Abstract: <PICT:0408180/IV/1> In an apparatus for steaming and drying webs, the web is passed between the surface of a rotating perforated drum, which may be cloth covered, and a permeable apron travelling with it; steam is sucked through the apron and web into the drum at one part of the travel and air is sucked through them into the drum at a subsequent part of the travel.  A heater in contact with the apron may be interposed between these two places.  As shown, a web k is guided between the perforated drum a and the apron h.  A chest o delivers steam which is sucked into the drum by pump f.  Rubber strips r seal the chest and apron junction.  A steam heated plate s dries the apron and web after steaming and during the remainder of their travel on the drum, air is sucked through them.  The fabric may be wound up on drum m or be carried out of the apparatus.  Guide rollers i<2>, i<3> are adjustable as shown in dotted lines to shorten the travel on the drum.

Title: Improvements in hair cloth looms
IPC: D03D41/00
Filed: 1929-10-28
Abstract: 337,190. Johnson, J. Y., (Feldstein Co., Inc., C. H.). Oct. 28, 1929. Stop-motions, shuttle and like.-In looms for' weaving hair, cloth, &c., the shuttle is provided with a member which engages a stationary member during the movement of the lay to open and close the hair gripping jaws, whilst provision is made for automatically interrupting the operation of the jacquard mechanism and cloth take-up mechanism and for disconnecting the hair takeup mechanism of the shuttle at one side until it functions properly at the other side. The loom is stopped automatically in the event of defective or incomplete shuttle action. A horizontal arm, 65, Figs. 2 and 4, pivoted at 66 on the lay, is pushed aside against spring action by an advancing shuttle and engages an arm 67 to rock a shaft 68 having a projecting arm 69. If the shuttle fails to reach its correct extreme position the arm 69 does not move, but remains in position to contact at the beat-up with trip mechanism to stop the loom. In addition, a plunger 71, Fig. 2, movable in a slide 72, is provided at each end of the loom and is arranged to be engaged at its rear end by a shuttle that failed to complete its travel. In this event the slide 71 engages an arm 73 of a rock shaft 74 which is connected with the loom stopping mechanism. Jacquards.-A roller 75, Fig. 4, is mounted on the lay in such a position that a hair withdrawn by the shuttle will pass over it. A second roller 76 is mounted uprightly adjacent this roller on an arm 77 attached to a sleeve 78 mounted on a pin 79 on the lay, the sleeve 78 carrying a stoppin 82 which bears against an arm 83 pivoted at 84 and having an extension 85 with a pin 86 which is engaged by an arm 88 of the arm 65 when the latter is advanced by the shuttle. This engagement causes the arm 83 to free the stop 83 allowing the roller 76 to lie over towards the body of the lay and in position to be engaged by a hair carried away from the container, which action causes the roller to be pressed back from the lay and causes a cam-shaped arm 80 to withdraw a pivoted arm 89 from the path of a shoulder 93, Fig. 2, of a rod 94 in the backward movement of the lay. If the shuttle fails to engage a hair at one side, the arm 89 pushes back the rod 94 and, by means of an arm, rocks a shaft 95 provided with an arm connected by a cord to the jacquard card cylinder turning catch, whereby this catch is lowered, thereby stopping the rotation of the cylinder.
