Title: Improvements in and relating to combing machines
IPC: D01G19/26
Filed: 1948-02-03
Abstract: 650,845. Combing machines. WHITIN MACHINE WORKS. Feb. 3, 1948, No. 3106. Convention date, Nov. 8, 1946. [Class 120(i)] [Also in Group XXIV] A planetary roll drive for a combing machine comprises a drive shaft 10, a drive gear 11 secured to the drive shaft 10, a second shaft 14 parallel to the drive shaft, a first driven gear 13 mounted on the second shaft and meshing with the drive gear, a second driven gear 23 mounted on the second shaft, a planet gear 19 meshing with both the first and second driven gears, a planet stud 20 supporting the planet gear and a planet stud supporting arm 21 mounted on said second shaft with freedom to oscillate relatively to the driven gears. As shown, the second shaft 14 is a rock shaft, the driven gears 13 and 23 being freely mounted thereon and the planet stud supporting arm 21 being secured thereto. The rock shaft is oscillated by means of cam roll 34 mounted at the end of a crank arm 35 secured to rock shaft 14, the cam roll 34 running in a track 33 in the cam wheel 32 secured to the drive shaft 10. The oscillation of the shaft 14 swings the compound planet gear about the axis of shaft 14 thus increasing or decreasing the speed of rotation of the gear 23 and thus the speed of rotation of the detaching rolls 26 and 27 which are geared thereto. The mechanism is so designed that the speed of the detaching rolls follows the following cycle:-acceleration, uniform speed, deceleration and reversal. The reverse rotation serves to feed back the previously detached tuft to receive the succeeding fringe in overlapped relationship.

Title: Method and machine for cleaning bottles, jars and similar vessels
IPC: B08B9/36
Filed: 1925-02-05
Abstract: 236,841. Holstein & Kappert Maschinenfabrik Ph÷nix Ges., and L³bbert, M. Feb. 5, 1925. Bottles, washing and cleaning.-In machines of the type in which the bottles are successively treated by washing, rinsing and if desired brushing in a number of sections, each section comprising an intermittently rotating cell-ring dipping into a trough of liquid, means are provided for spraying the bottles, within and without, with fresh cleaning liquid before they leave each section. The spraying liquid in each section may be the same as the soaking liquid in the following section or clean water may be used for spraying in each section. The spraying-devices are capable of being rocked and shaken to eject pieces of broken glass. The cell-rings 2a, 2b, 2<c> run on rollers 50 in troughs 1<a>, 1<b>, 1<c> and the bottles fed at 8 on to an intermittently-moving band 7 are pushed into the cell-ring 2<a> by a reciprocating bar 11. After one revolution of the cell-ring the bottles are ejected on to the band 7 by pushing- members 20 on a bar 10 and are transferred to the cell-ring 2<b> and so on through each cell-ring until they are transferred by a pushing- member 16 on to a conveyer 9. Spraying-devices 17<a>, 17<b>, 17<c> are arranged to act on the bottles when they are at the upper part of each cell-ring. the devices being carried by two channel-bars 18, 19 extending the whole width of the machine and each device comprising pipes 21 with nozzles 22 supplied with liquid by flexible pipes. Each nozzle 22 has above it a centering cup 24 and the bars 18, 19 are carried by transverse beams 25 movable vertically on rods 26 and supported by springs 27. Pivoted levers 28 connect the transverse beams 25 with thrust rods 13 actuating the ejecting and drawing-in bars 10, 11 so that the spraying-devices are raised and lowered during each pause in the movement of the cell-rings, thus spraying the insides of the bottles. The outsides of the bottles are sprayed during the movement of the and a channel 40 arranged helow the spraying-device comes off the spraying liquid. Each spraying-device includes two pivoted carriers 29, 30 for the centering cups 2'4 each carrier being connected by a link 36 with a bell-crank lever 33 pivoted to the transverse beam 25 and operated by a draw-rod 37. Moving the draw-rod 37 outwardly tilts the carriers 29, 30 into the position shown in Fig. 4 in which position they may be shaken to remove pieces of glass. A stop 39 on the draw-rod 37 retains the carriers in their operative position when the drawrod is pushed in.

[Classes 80 (i) and 80 (ii)] [Also in Group XL] A gearing mechanism for enabling a driven shaft to be adjusted in angular relation to a driving shaft during rotation for use in picture telegraph machines for phasing the synchronized transmitting and receiving station motors, comprises an oppositely acting ratchet clutch with spring-pressed balls 8 between a gear ring 5 secured to a worm wheel 4 driven by a worm 3 of the driving shaft 1 and a sleeve 6 fixed on the driven shaft 2. Freely mounted on the sleeve 6 is another gear 10 of equal diameter to the gear 5 and having projections 11 arranged between the balls 8 of the ratchet clutch. The gears 5, 10 are adapted to be engaged by either of a pair of gears 14, 15 or 16, 17 these gears all being of the same diameter but gears 14 and 17 having one tooth more than gears 15 and 16 so that according to which pair is engaged by rocking the carrier member 12 the gear 10 is driven slightly slower or faster than the gear 5. This results in the projections 11 disengaging one or other of the sets of balls 8 of the ratchet clutch to slow down or speed up the sleeve 6 and driven shaft 2 until the desired adjustment is effected when the carrier member 12 is set in its neutral position in which the ratchet clutch drives solid.

Filed: 1940-02-29
Abstract: 539,791. Hydraulic torque converters. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. Feb. 29, 1940, No. 3798. Convention date, March 24, 1939. [Class 69 (ii)] A hydraulic torque converter is constructed with a rotating housing 5 coupled to a driving- shaft 1, pump blades P being fitted to the housing 5 which for direct drive can be connected by a coupling 9, 10 to a sleeve 15 fitted with a gear 14 geared to the ouptut shaft 21. When a fluid drive takes place the connection 9, 10 is uncoupled and at starting or at low speed the pump P drives turbine blades 6, 7 on members attached to hollow shafts 13, 12 respectively, the blades 6 rotating in the same direction as the blades P and the blades 7 in the opposite direction. A guide blade ring 8 is used attached to a sleeve 11 which is prevented from rotation when a forward drive takes place by means of a freewheel coupling 26 including a fixed ratchet 24. At starting both the members 6, 7 transmit power and the member 7 drives by a disengageable coupling 22, 23 a gear which is geared to a gear 20 on the shaft 21 by an intermediate gear not shown. At a pre-determined speed the coupling 22, 23 disengages and the drive is effected by the member 6 only. For reverse drive a coupling 16, 17 is active as is also the driving members 24, 25, but the gear 14 is not in action. The driving-liquid is supplied by a pump driven by the engine to a pressure pipe connected to a nozzle 29 from which it passes to a conduit 27, suitable packing members, which are also bearing members, bearing on the parts 11, 12, 13 being provided. In a modification, Fig. 4, the rotating housing 41 is connected rigidly to the driving-shaft 42, and the pump blades 43 can be adjusted by means of gear wheels 45, 46 so as to vary their action. Cooling fins are fitted to the rotating housing in both modifications.

Abstract: 539,279. Cellulose esters. BRITISH CELANESE, Ltd. March 2, 1940, No. 3941. Convention date, March 4, 1939. [Class 2 (ii)] A primary esterification solution of a cellulose ester which has been prepared under conditions which lead to the presence of a proportion of sulphur compounds in the product is refined and stabilized by adding a polyhydric alcohol to the solution and allowing the mixture to stand until the desired solubility has been attained by the ester; a primary esterification solution is one in which the excess esterifying agent, e.g. anhydride, has been rendered ineffective by the addition of just sufficient of an appropriate reagent but before the catalyst has been neutralized. Preferably a mixture of the polyhydric alcohol, e.g. glycol or glycerine, with water is used, e.g. 1-6 parts by weight of glycerine with 2 parts by weight of water is added to a primary esterification solution which has been prepared in the presence of a substantial proportion of sulphuric acid and the mixture is allowed to stand at ordinary temperature, e.g. 24‹C. for a period of about 19-24 hours. Examples are given.
