Filed: 1934-06-29
Abstract: 430,385. Centrifugal machines. KOCH, H., 116A, Leipzigerstrasse, Chemnitz, Germany. June 29, 1934, No. 19324. [Class 23] The scoop for discharging solids from a centrifugal machine is actuated by fluid pressure means to move axially to and fro along the drum, and also to adjust the radial position during such movement. The position of a skimming tube to discharge liquid is also adjusted by fluid pressure means. The machine shown has an horizontal axis, and the scoop 7 on the rod 14 with its associated parts can be lifted by the piston 13 in the cylinder 12 to increase the depth of the shaving made by the scoop. The rod 14 is attached by a rigid coupling 16 to the piston 15 in a cylinder 11, and the flow of fluid to this cylinder is controlled by valves having single and double pistons 18, 19 in cylinders 9, 10 respectively. The pistons 18, 19 are joined by a lost motion connection 20, 21. The control valve 8 is rotated by a weighted lever 17 operated by a finger 49 on the control rod 48 which is moved at each end of the stroke of the scoop 7 by the engagement of the coupling 16 with one of the collars 46, 47. A charging valve controls automatically the supply of material to the drum but it is itself subject to the control of the main manually-operated valve 3. The main valve 4 can be used to control the position of the skimming tube irrespective of the automatic control mechanism, and the valve 5 overrides the automatic control mechanism for the scoop 7. Some of the pressure fluid tubes have telescopic connections 53, 54, 55 to permit the vertical movement of the scoop and its operating mechanism.

Title: Improvements relating to rotary plug cocks or valves
IPC: F16K5/16
Filed: 1930-06-26
Abstract: 352,228. Plug cocks. HUHN, G., 23, Levetzowstrasse, Berlin. June 26, 1930, No. 19510. [Class 135.] In a rotary plug cock, means for axially easing and jamming the plug in its seating comprise a rotary annular member 16, 20, Fig. 1, screwed on the plug stem 21, 22, as shown, and operated by the handle 29. A pin or key 23 inserted through the stem projects into slots 24 in the annular member so that after the axial movement due to the screw arrangement the ends of the slot abut against the pin or key 23 and effect the rotation of the plug. The open and closed positions are located by the ends of the key striking the ends of arcuate slots 26 in the flange plate 25. A screw plug can be inserted at 19 for temporarily preventing or limiting the axial displacement. An internal spring may be inserted to act on the large end of the plug, or an external spring on the extended stem between the annular member and nuts on the stem, to increase the friction between the plug stem and annular member. In order to provide for easing or jamming the plug at any desired opening, the handle 55, Fig. 11, is pivotably mounted on the annular member and engaged, when desired, with the stem by means of a notch and tooth arrangement 51, 56. In a modification, the handle is slidably arranged and a tooth thereon engaged in a notch on the annular member by an enclosed spring.

Title: Improvements relating to fabric measuring machines
IPC: G01B5/04
Filed: 1949-07-26
Abstract: 678,930. Counting apparatus. COCKETT, J. A. July 26, 1950 [July 26, 1949], No. 19610/49. Class 106 (i). [Also in Group VIII] In a fabric measuring machine of the kind in which a " units " indicator is driven intermittently by a " fractions" indicator driving means, the " units " indicator comprises a tape which bears a " units " scale and which is unwound by a member driving the " fractions " indicator. Indicator mechanism.-As shown, measuring roller 20 is mounted on a shaft 21 and drives through gears 29, 30 a counter-shaft 31 carrying " fractions " indicator discs 32, 35 and a sliding sleeve 47 carrying a disc 48 driven from gear 30 by pins 49. Lugs 49<SP>1</SP>, Fig. 6, on disc 48 advance star wheels 41, 42 on shaft 39, 40 one tooth for each revolution of the " fractions " indicators. Two pairs of spools 43, 44 are carried by shafts 39, 40 and as the star wheels rotate one tooth distance a tape 45 carrying " units " graduations is wound from one spool of each pair to the other the distance of one unit graduation. Indicators 32, 35 and rear tape 45 are observed through windows in an outer casing; the front tape 45 is observed through a mirror 95. When a desired length of fabric has been measured (see Group VIII), depression of a knife lever causes a fork member 61 to move sleeve 47 along shaft 31 so that disc 48 is drawn out of range of star wheels 41, 42, fork 61 being held in its displaced position by a catch. Be-setting.-The machine is re-set by depressing a re-setting lever 108 (not shown), which is freed from a locking device when the knife lever is depressed. Depression of the re-setting lever produces the following results: (a) a lever 104, Fig. 6, is depressed to rotate a cam 128 and remove pawls 51 from star wheels 41, 42, thereby allowing tapes 45 to return to zero position under the influence of a torsion spring on shaft 39; (b) a tension spring attached to an eccentric pin on disc 32 is stressed so that the pin moves to its lowest position and both " fractions " indicators are returned to zero position, simultaneous movement of a cam member acting to displace the pin from the top dead centre position should it be in such position; (c) the catch holding fork 61 is moved to allow fork 61 to return to the position shown in Fig. 5, disc 48 moving rearwardly into engagement with the star wheels; a stop member 133 which moves downwardly with lever 104 to a position between gear 30 and disc 48 prevents the latter engaging the star wheels before they have finished their rearward rotation and lever 104 has risen again. When the machine needs resetting an indicator shows the word " RE-SET " at a further window in the top of the machine casing. Automatic stop mechanism.-A pin 136 on a nut 135 threaded to shaft 40, Fig. 5, engages an adjustable stop 137 to provide automatic stopping when a predetermined length of fabric has been measured off.

Abstract: 966,888. Friction clutches. AUTOMOTIVE PRODUCTS CO. Ltd. May 25, 1962 [June 1, 1961], No. 19816/61. Heading F2C. An automatic adjusting device, for taking up wear in a twin disc clutch, comprises an axial pin secured to the driving member of the clutch, and a spring steel washer associated with the intermediate drive plate of the clutch and movable along the pin in one direction only, the washer being shifted progressively along the pin as wear of the clutch plates takes place. As shown in Fig. 1, a twin plate clutch comprises a driving flywheel 7, an intermediate drive plate 6 and a further drive plate 8. A pin 1 is secured to the flywheel 7, and a spring steel washer 2 mounted on the pin is located with play in a slot 9 in the intermediate plate 6. The washer is dished and has radial slits providing tongues 4 which permit axial sliding of the washer along the pin towards the flywheel 7, axial load .applied to the washer and tending to move it in the opposite direction causing the tongues 4 to grip the pin 1 and restrain such axial movement. The play between the washer 2 and the walls of the slot 9 thus determines the disengaged position of the intermediate clutch plate 6, and the washer is shifted along the pin 1 as the clutch plates wear to maintain the clearance between the clutch plates constant when the clutch is disengaged irrespective of wear. Fig. 7 shows the wear adjuster applied to a twin plate clutch which is engaged by a diaphragm spring and which has a flywheel 18 connected to an intermediate drive-plate 19 by tangential drive straps 20. In this embodiment the spring steel washer 2 of the adjuster is disposed in a gap 21 provided between a recess formed in one face of the intermediate drive plate 19 and the outer end portion of the strap 20 which extends over the recess. The pin 1 is screwed into the flywheel 18 and passes through clearance holes in the strap and the intermediate drive plate. In a modification of this arrangement the steel washer 2 is disposed in a slot in the intermediate drive plate as in the first embodiment. The spring steel washer may have gaps between the tongues instead of radial slots.
