Title: Improvements in or relating to looms for weaving chenille fabrics
IPC: D03D39/00
Filed: 1929-08-07
Abstract: 332,766. Morton, J. Aug. 7, 1929. Dobbies; pattern surfaces; driving arrangements; stop-motions controlled by dobby.-In a loom for weaving chenille fabrics, the gearing for actuating the fur carrier is controlled by a dobby, which also controls a stop motion and the needle frame as well as the shuttle-box and picking motions and the healds. The timing of the fur carrier can thus be varied by varying the arrangement of the bowls or pulleys on the dobby control chain. The fur carrier is traversed across the loom on a bar by an endless rope passing around pulleys, one of which has an attached sprocket wheel driven by a chain 46, Fig. 2, from a sprocket wheel 47. A dobby vibrator 18<1>, Fig. 4, controls the fur carrier movements by means of a spring-controlled shaft 57 which is connected to a bell-crank 56 carrying a fork for moving a sprocket wheel 47 driving the fur carrier into engagement with a brake element 54 for maintaining the fur carrier stationary, or into engagement with a driving element 52 on the belt pulley 53 whereby the. fur carrier is moved. A dobby vibrator 18<4> operates a rod 34 carrying a one way striker 37, which actuates an arm 91 connected by lever mechanism 92 to the shaft 93 carrying the loom starting handle 62. The shaft 93 is thus rotated to stop the loom by opening the main clutch 61. After the inserted fur has been adjusted the loom is restarted by the handle 62. The dobby vibrator 18' controls the needle frame, which is counterbalanced by weighted levers. The dobby may comprise eight sections, each comprising two lag chains 10, 11, Fig. 3, one vibrator lever, one vibrator 18, two gear segments 16, 17, and one connector link &c. In order that the timing of the various motions actuated may be adjusted relatively to one another, gear segments 16, 17 may be angularly adjustable individually or in sections on their shafts 14a, 14<b> and be held together by bolts passing through arcuate slots. In the arrangement shown, independent gears 16<b>, 16d, Fig. 4, control the vibrator segments 18<4>, 18<8> for the stop motion and needle frame respectively, the gear 16b being set back so as to operate the stop motion later than the other parts. One gear 16<a> is used for the vibrators 18<1> to 18<3> controlling the fur carrier, the shuttle box motion and the picking-motion, and another gear 16<c> controls the vibrators 18<5> to 18<7>, which actuate the healds through jack levers and cords. The vibrators are controlled by levers carrying bowls 20, or having convex faces cooperating with bowls and spacers on the lag chains 10, 11 driven intermittently by a Geneva wheel operated by a driver on the shaft 14<a>, which is geared to the shaft 14b driven by the loom crank shaft, or the lag chain may be driven continuously and be furnished with pairs of links 100 spaced apart by connecting rivets 101 and having flat and convex removable pieces 102, 103, or varied convex pieces, or the chains may have faced blocks to which convex pieces &c. are screwed. Specification 332,675 is referred to.

A hawser 7 is connected at 8 to side plates of the conveyer 1 fixed to the support 2, and passes round a drum 6 connected by the slipping clutch gear to the motor 4. The articulated conveyer is moved step by step as the auxiliary conveyer is extended to its maximum length. The auxiliary conveyer may have loop take-up gear to vary the length of the belt or it may be movable bodily. The articulated conveyer may be held in any desired position by adjustable props 15 and the discharge end may be mounted on a carriage and held by clamps.

Abstract: 683,534. Acoustic lenses. WESTERN ELECTRIC CO., Inc. Sept. 23, 1949 [Oct. 1, 1948], No. 24488/49. Class 13. An acoustic lens is made up of a large number of rigid bodies arranged to fill the shape of an optical lens. Since each rigid body has the effect of reversing the phase of a sound wave, the presence of several such bodies in the thickness of a lens delays the sound whereby a lens such as that shown in Fig. 3 has a converging effect on sound and a divergent lens, Fig. 19, placed in front of a loudspeaker spreads the sound. A framework of rods, Fig. 6, may carry a large number of discs, or plaited strips or perforated plates, Figs. 11-17 (not shown), may be used. Alternately, a number of parallel plates, Fig. 20, may produce a focussing effect because the paths CBA, FEDA, IHGA are of the same length.

Foaming agents specified are sodium bicarbonate and pp1-oxy-bis (benzene sulphonyl hydrazide).  Curing catalysts specified are the naphthenates of iron, zinc and cobalt. Examples are given in which the preparation of foamed polysiloxanes composed of (1) monomethyl-, dimethyl- and monophenyl-siloxane units, and (2) diphenyl-, phenyl-methyl-, monomethyl- and mono-phenyl-siloxane units, is described.  The process may be adapted to make foam blocks or for producing foams in situ, e.g. in structural members. The foams are useful as low density reinforcing cores in sandwich construction, as insulation in fire walls, and as a buoyant float in rafts and other life-saving equipment.

[Also in Group XXIX] A variable-speed gear comprises a throttled gear pump of which one wheel 37 is fast on an input shaft 36, whilst a meshing wheel 38, carried planet-wise in a freely-rotatable housing 44, is fast with a planetpinion 40 meshing a sun 41 on a final output sleeve 42 carrying an output gear-wheel 43, the pump serving to transfer oil from an external reservoir 45 to a pressure space inside the housing 44 and thence back to the reservoir through an outlet duct 55, which is inclined in the direction of and angularly spaced from the pump inlet 50, and includes a centrifugal and pressure-responsive control valve 53 for throttling the outlet duct to produce an eventual oneto-one drive. Vanes 76 on an impeller 75, in the reservoir space 45 and secured to the output sleeve 42 or input-shaft, feed oil towards the pump inlet 50 on starting and maintain uniform angular speed of the oil in the reservoir during running. The control valve 53 comprises a tube 53, Fig. 3, with ports 58, 68 which control inlet and outlet ducts 52, 55 as the tube is turned, by a centrifugal mass 59 on an arm 63 damped by a dashpot 61, or by equivalent balls, rollers, chains or cables in a duct. Housing pressure also acts on a spring-loaded piston 67 to increase the flow at high pressures. Excess pressure in the reservoir 45 is relieved to the housing through a spring-loaded valve 71. A definite minimum ratio is provided by a ball detent 25 preventing the housing 44 from reverse rotation and also having an arm 28 which pushes the centrifugal lever 63 radially inwards to open the control valve 53 fully during fixed ratio drive.

Abstract: 379,519. Hydraulic transmission of power. NATIONAL AUTOMATIC TOOL CO., Richmond, Indiana, U.S.A. Sept. 5, 1931, No. 25010. Convention date, June 23. Addition to 378,003. [Class 69 (ii).] The control valve of the parent Specification is disposed in the lines connecting the pump and motor, and is adapted to serve as a distributing valve and to control means for varying the pump capacity. The control valve casing has ports 34, 38, Fig. 3, connected to the motor cylinder 9, a port 44 connected to a constant capacity pump 16, ports 58, 59 connected to a variable capacity pump 14, an exhaust port 63a, and a port 54 connected to a cylinder 51. When the valve is in its initial neutral position shown in Fig. 5, the ports 34, 38 are connected, and the high pressure liquid entering through the ports 58, 59 joins the output of the pump 16 and escapes through a relief valve 46. Rapid traverse forward is obtained when the valve is in the position shown in Fig. 6, liquid from the pump 16 passing via the hollow valve, chamber 71 and port 54 to the cylinder 51, thereby actuating a piston 52 to increase the output of the pump 14. Slow feed and rapid reverse traverse are effected when the valve positions are as shown in Figs. 7 and 8 respectively, and there is a final neutral position when the valve is in its extreme left-hand position. Normal and emergency actuation of the valve is effected as in Specification 378,009.
