Title: A self-releasing clasp device suitable for under-water markerbuoy release
IPC: A01K93/00
Filed: 1965-05-19
Abstract: 1,110,431. Releasing marker buoys; marine mines. ANSSI TOIVO TAPANI ELO. 19 May, 1965, No. 21264/65. Heading B7A. [Also in Division E2] A self-releasing fastening device suitable for under-water marker-buoy release comprises in combination a hollow outer water-tight casing 4, a coiled line, a clockwork timer mechanism 3 located within the easing, and a releasable fastener 12, 15 which is manually settable in the fastening position but is releasable by the action of the clockwork timer mechanism at a preset time setting thereof. In the embodiment shown a line 1 has one end part A secured to a weight and to an eye 17 on the casing 4, a central part wound in coils 11 round the casing, and its other end part B secured to a float or marker buoy so that when submerged the easing assumes the position shown. The fastener comprises a spring 12 urged by its own resilience to a releasing position, and an engaging member 15 passing through the casing 4 and having a bent end portion which holds the spring 12 in the fastening position shown in which it retains a loop 14 attached to the line part B. The other end portion 15<SP>11</SP> of the member 15 is bent so that it lies in the path of a hand 16 of the timer mechanism 3 so that after a preset time the hand contacts the portion 15<SP>11</SP> to rotate the member 15 thus releasing the spring 12 and loop 14 and permitting unwinding of the coils 11 to allow the float or marker-buoy to surface. Access to the controls of the timer mechanism is obtained by removing a cover 6 screwed on to the casing 4, and a dial 26 over which the hand 16 moves is viewed through a transparent end plate 5 when setting the timer mechanism. A plug 19 of packing material in a bore 18 surrounds the member 15 and is held in place by a plug 20. The spring 12 passes through the plug 20 and a surrounding bracket 13. In other embodiments the cover 6 is of plastics material and snaps into place, and the loop 14 is of a material which dissolves in water to that after a period of time the line is released even if the timer mechanism fails. The line 1 may be wound round the float instead of the casing 4 and may have an end loop engaged directly under the spring 12. The device may be made bouyant so that it rises to the water surface after release. Instead of the member 15 being rotatable it may be made to slide when operated on by the hand 16.

Title: Improvements relating to flushing cisterns
IPC: E03D1/30
Filed: 1951-09-10
Abstract: 693,410. Water - waste - preventing cisterns. MEIK, O. A. Sept. 10, 1951, No. 21289/51. Class 26 In a water-waste-preventing cistern, a valve member in the form of a cylinder 9 open at its top is constrained to move vertically above the outlet 7 by lugs 9a engaging guides 9b, and a counter-weight 16 retains it in the raised position until the water level falls below the valve member. In operation, turning of the handle 17 rotates the spindle 12 which both raises the valve member 9 through the crank and pin arrangement 11 and 10a, and also turns the counterweight rigidly attached to it into a position where the torque it exerts on the spindle is sufficient to retain the valve member in its raised position. When the water level falls, the effective weight of the valve member increases and it returns and closes the outlet. The rod 10 is made hollow to reduce noise by admitting air to the discharge pipe after the outlet is closed. The tank is refilled by a known ball-valve arrangement.

Abstract: 669,934. Pneumatic tyres. FIRESTONE TIRE & RUBBER CO. Aug. 17, 1949 [Sept. 2, 1948], No. 21444/49. Class 144 (i). In tyre-building machines having stitchers capable of movement in more than one direction, e.g. axial and transverse to the axis of the building-drum, means are provided whereby (a) the angle between the stitcher and the drum is variable, as by linkage-mechanism, through continuous range of adjustment independently of other movements; (b) the stitcher is adapted for independent arcuate movement generally axially of the drum; and (c) the stitcher is adapted for independent dipping movement as a whole about a line parallel to its axial movement. Figs. 1 and 2 show the general layout of the stitcher mechanism with the stitchers 13, 14 in different positions on the work at opposite ends of the drum 10, the mechanism being mounted on a slide which is movable towards and from the drum by means of a hand wheel and rack-gears. Progress of the slide during the actual stitching operation is effected by power-driven means shown in Fig. 10. Arranged for engagement with the hand wheel 20 are driven high- and low-speed frictionwheels 25, 26 and a reverse-drive wheel 27, the selective engagement being controlled by hand levers 34, 44a. Relative adjustment of the stitchers is effected from a shaft 49 having oppositely-threaded ends carrying travelling nuts 56 which are pivoted on arms 54 connected to the stitchers by parallelogram linkage comprising links 61 rigid with the fixed arms 54 so as to determine the position of the working- points 60 of the stitchers. Tilting of the stitchers is effected by swinging about a cross-shaft 49 by means of cranks pivoted on an angularly-adjustable rod 81 journalled on the stitcher-table. For co-ordinating mutual approach and independent orientation of the stitchers, a bell-crank lever pivoted on a bracket 98 on the stitcher-table has one arm 99 pivoted to a tie-rod 100, the other end of which is attached to the lever 88 which controls the stitcher-actuating linkage. The other arm 101 of the bell-crank is positioned for engagement by a lug on a slide 103 adjustable along the hand lever 64. The slide is so positioned on the lever 64 that after operation on the plies over the rounded edge 104 of the drum, the lug clears the arm 101 and the stitchers then maintain a constant angle with respect to the drum.
