Title: Improvements in or relating to elastic couplings
IPC: F16D43/21
Filed: 1931-07-28
Abstract: 391,787. Control of motors. KASTNE-R, A., 4, Hortensienplatz, Lichterfeld- West, Berlin. July 28, 1931, No. 21599. Convention date, July 28, 1930. [Class 38 (iii).] An electric motor is switched on or off, or its speed is regulated, by means of an actuating device controlled by the overloading of an elastic coupling combined with a clutch. A controlling sleeve 28<1> of the coupling is moved axially under the influence of the driving torque against yielding means, and has mounted, on a fine screw-thread, a sleeve 42 carrying with it, for axial movement, a flanged sleeve 44 having a toothed rim 46 connected with the actuating-device (not shown). When the coupling commences to rotate forwardly, the sleeve 42, held from rotation by a light detent 45, screws along the control sleeve 28<1> to an extreme position determined by a loose ball 47, and the detent 45 then slips idly over fine teeth on the sleeve 42. Any overload which thereupon ensues moves the control sleeve together with the-sleeves 42, 44 axially until a flanged part 48 of the sleeve 44 abuts against a ring 12 rotating with the coupling. The sleeve 44 is then carried along frictionally with the ring 12 and rotates the actuating- device to perform the desired function. The actuating-device may be returned to its initial condition by a reversal of drive or by a spring or weight after the overload is passed. When the limiting torque is not required in accordance with the number of revolutions made by the coupling, the threaded connection may be omitted, the sleeve 44 then resting directly on the sleeve 281.

Title: Stop-valve
IPC: F16K3/18
Filed: 1921-08-15
Abstract: 167,782. Fischbach, R. Aug. 13, 1920, [Convention date]. Sliding valves; wedging or jamming. - The valve discs of a sliding gate valve are moved by the spindle into position in front of the seatings, and are then pressed against the seatings by screw gear. The valve casing a is provided with a cap d supporting a sleeve i for the screwed spindle h. A cross-bar i<1> on the lower end of the spindle carries the pivots for two links l, the lower ends of which are pivoted to cranks n carried by two screwed spindles n<1>. The spindles are separated by a ball bearing and are connected by a bolt q. The valve discs o are made non-circular to prevent rotation, and are guided by slides s in the casing. Stops t are provided to limit the turning of the cranks n. When the valve is lowered bv operating the spindle h, no rotation of the spindle n<1> takes place until the discs o reach the bottom of the casing. Further downward movement of the spindle h then rotates the spindles n' so as to press the discs o against their seatings. In a modification, Fig. 5, a pressure-balancing device is provided in each valve disc. A small check valve u is arranged in a central opening v which is connected with the valve casing by means of openings w. When the valve is being opened, the disc which is under pressure leaves its seating, but the other disc may not do so. The pressure liquid then passes into the casing and lifts the check valve from the other disc so that this disc is also placed under pressure and moves from its seating. If the valve u is not lifted by the pressure, it will be positively lifted on screwing the spindles n<1> further into the valves o. The jointing material p may be placed in a recess in the valve and the seating may be provided with a corresponding circular rib.

Title: Improvements in or relating to cop-changing mechanism for weaving looms
IPC: D03D45/20
Filed: 1952-08-29
Abstract: 733,082. Looms. KEAY, Ltd., T. C., KEAY, W. F., and KEAY, T. A. C. Aug. 31, 1953 [Aug. 29, 1952], No. 21739/52. Class 142(2). In a loom having cop-changing mechanism including a cop feeler working in conjunction with a weft-detecting finger adjacent one selvedge of the cloth, the weft-detecting finger is so coupled to the loom starting handle that when the handle is moved to the " off " position the finger is moved to an inoperative position, and does not become operative again, on restarting, until the second pick. The finger 1 is pivoted to a member 2 attached to a radius rod 3. A lever 7 pivoted to the member 2 is engageable with an arm 5 of the finger 1 and also with a detent 9. On stopping the loom by moving the starting handle 14 to the off '' position, the handle moves a bar 12, an inclined end of which comes against the adjacent end of the lever 7 to swing the lever and thereby raise the arm 5 out of the path of a hammer 6. The detent 9 retains lever 7 in this position. When handle 14 is moved to the starting position the bar 12 is disengaged from lever 7, but the finger 1 remains inoperative, until, on reciprocation of the hammer 6 a bar 15 attached thereto disengages the detent 9 from the end of the lever 7 which thereupon allows the arm 5 to fall. Specification 652,580 is referred to.

Abstract: 1506536 Charging glass melting furnaces LIBBEY-OWENS-FORD CO 26 May 1976 [15 June 1975] 21785/76 Heading C1M [Also in Division F4] In a glass melting tank-type furnace 20 glass making materials fed into the doghouses 25, 26 are deposited in strip formation on to the surface L of molten glass and then compacted against the molten glass surface by a reciprocally supported pressing member 44 that also moves the material forwardly against previously deposited compacted raw material. Each doghouse has apparatus 32, 33 for feeding material to the furnace and a compacting and moving device 34 that includes the pressing member 44 supported by two arms 49, 50 (Fig. 3). The arms are mounted between rollers 72, 73, 75 in a framework 45 and are reciprocated by a chain 91 driven by the assembly 46. Limit switches 94, 95 actuated by a member 96 (Fig. 3), control the reciprocating limits of the arms 49, 50 and hence the pressing member 44. One end of the framework 45 is moved up and down by a crank mechanism 47 (Fig. 2) with the framework pivoting about the pins 67. This movement is controlled by a limit switch 112 also actuated by the member 96, and is arranged so that downward movement of the pressing member 44 starts in the intermediate position (Fig. 2). The member 44 continues to advance during its lowering movement and as it compresses the batch material it also moves it forwardly into the melting furnace. At the limit of forward travel the switch 112 again operates to raise the framework 45 as the arms 49, 50 move the member 44 on the return stroke. The member 44 and arms 49, 50 may be cooled by water from the supply and drain pipes 57,58 (Fig.3). A skim blade (114), Fig. 5 (not shown), may be attached to the pressing member to assist in pushing the batch forwardly.

Abstract: 402,543. Dressing fish. ROWTON, J. L., 7, Dovanha Gardens, Aberdeen. Aug. 9, 1932, No. 22280. [Class 28 (ii).] In a fish-dressing machine, the ventral and pectoral fins and the belly flaps of the fishes are trimmed off by disc knives 15 which are mounted on arms 8 arranged to swing about on axis 9 and counterbalanced by weights or springs 12, and the knives 15 are journaled in a mounting 5 which is itself oscillatable about the axis 6 at the ends of the arms 8. The swinging of the mounting 5, and consequently the angle of incidence of the knives relative to the fish, is regulated by bobbins or guides 24, adjustably mounted at the ends of arms 25 adjustably secured to the mounting. In operation, the fish is conveyed tail first, and belly upwards, towards the knives. On meeting the first bobbin 24, the knives are tilted to give the correct initial angle of cut, and when the second bobbin is encountered, the horizontal position of the knives is restored. During this period, the mounting 5 is also raised bodily about the pivot 9. When the fish clears the first bobbin, the angle of cut is reversed, the knives thus making a deeper-cut following the line of the belly cavity. The swing of the arms 8 is limited by a rod 16a working in a slot in the bracket 14. In a modification, the fish is carried on its side and the knives cut in a vertical plane.
