Title: Improvements in or relating to combined washing and wringing machines
IPC: D06F45/18
Filed: 1920-11-12
Abstract: 153,874. General Railway Signal Co., (Assignees of Howe, W. K.). Nov. 12, 1919, [Convention date]. Washing-machines with enclosed rotary receptacles; wringers, attaching to washing-machines, driving gear for.-In a combined washing and wringing machine, the operating mechanism is enclosed in a single casing 16 secured at three points 19 to the machine framing. A vertical extension 17 of this casing supports the wringer which can swing about this vertical support and is readily detachable from it. The gear casing contains a heavy lubricant and means are provided for ensuring access of the oil to the various bearings. The washing drum D is rotarily oscillated by means of a pivoted toothed sector 58 which meshes with a pinion 57 splined on the driven shaft 15 and is connected by a rod 59 and pin 61, with a worm wheel 53 driven by a worm on a vertical drive shaft 48. The above-described mechanism is mounted and enclosed in the casing 16 which has a lower extension 18 to house the shaft 48 and its driving means comprising a worm wheel 47 and a worm 43 on a shaft 27. A motor M is connected with this shaft 27 by an universal coupling 28, 28<1> and a friction clutch FC which are encased by a sleeve 29 secured at one end to the extension 18 and at the other to, but insulated from, the armature shaft bearing 26. The driven shaft 15 is slidable by means of a handle 76 and an eccentric pin 79 engaging a groove 80 in the shaft so as to thrust the triangular end of the shaft into or withdrawn it from a correspondingly shaped opening in the gudgeon boss 13 on the drum. When the shaft 15 is withdrawn the drum may be removed or the boss may rest on a semicircular rib 85 secured to the bearing bracket 84 which is adjustably bolted to the tub T and casing 16. The wringer is carried by an arm S cast in one with a cup-shaped gear case 94 and an annular recessed hub 95 which rests on the tapered flange 96 formed at the upper end of the gear casing extension 17. A tube 101 secured to the support S passes down the extension and finds a bearing at its lower end between three projections 102. The hub 95 carries a spring-controlled locking pin 99 adapted to enter one of a number of holes around the flange 96 so as to hold the wringer in any of the positions to which it may be swung. Within the tube 101 is a shaft 121 connected by pins and bifurcations with the driving shaft 48 and the spindle 119 driving the wringer through reversing-gear and a horizontal spindle 105 coupled universally to the lower roller shaft. The slidable clutch 112 of the reversing gear is operated by a handle 81 mounted on the casing cover 117 and provided with retaining means. The casing 16 contains lubricant up to the level K and the arms of the sector 58 are channelled to pick up the lubricant from the sump 125 and supply it to the various bearings. A passage allows the oil to flow to the worm gearing 47, 43 and another duct delivers it to one end bearing of the shaft 27.

Abstract: 763,965. Coating yarns; coating webs. TOOTAL BROADHURST LEE CO., Ltd. March 5, 1954 [Dec. 18, 1952], No. 32077/52. Class 140. A length 1 of material to be coated or treated with a substance dissolved, dispersed, or emulsified in a liquid, is passed between two rolls 2 and 3, to one or both of which the liquid containing the treating substance is fed at a rate greater than that necessary for the intended rate of take-up by the material, e.g. by a pump 5 from a mixing tank 4 to a reservoir 6 one wall of which is constituted by the roll 3. The excess liquid is returned, e.g. through a hopper 13 and pipe 14, to tank 4 which is fed with concentrated liquid at a uniform rate such that the rate of feed of the contained treating substance is the desired rate of take-up by the material, e.g. 1, by a metering pump 21 from tank 20, and is also fed with a diluting liquid from tank 22 the supply of which is controlled by a liquid level detector in tank 4 to keep the contents of the tank at a fixed volume. Thus the concentration of treating substance in tank 4 will be reduced if the rate of take-up by the material is too great. The pipe line leading from tank 20 to metering pump 21 may include a feed pump delivering at a rate greater than that of the metering pump, and a branch pipe leading from the pipe line just before the metering pump and returning to the tank, to cause circulation of the concentrated liquid. The reservoir 6 to which the treating liquid is fed from tank 4 may be the upwardly facing nip between two rollers lying side-by-side. The treating substance may be dye or size and the diluent, hot water. The material treated may be one or more filaments, yarns, or threads, ribbon or web of fabric or paper.

Title: Combined gear change and clutch release for motor cars and other services
IPC: F16H61/02
Filed: 1936-11-24
Abstract: 478,453. Changespeed gearing. NICOL, T. S. Nov. 24, 1936, No. 32111. [Class 80 (ii)] Change - speed gearing suitable for vehicles comprises a toothed pinion 20 slidable on a driven shaft 19 by a mechanical relay set in motion by a manual lever 48, Fig. 1. For forward speeds, the pinion 20 is meshed alternatively with gears 17, 18 of equal size loose on a shaft 15 and driven at different speeds from a driving-shaft 11 which carries a gear 14 meshed directly by the pinion 20 for reversed drive. Between the pinion 20 and a transverse arm 22 which operates it, is a double-acting spring barrel 21, Fig. 2, with two springs 34, 36 and stops arranged so that the stroke of the arm 22 can be completed in both directions, and the pinion 20 follows into mesh when it can. The relay striking movement is effected by pivoting the arm 22 about the shaft 19 so as to bring two half-nuts 24 carried by the arm into engagement alternatively with screws 25, 26 constantly driven in opposite directions from the engine shaft 11. To effect a gear change, a quadrilateral slide 45 is slid axially by the hand lever 48. By oblique guides 44, a shuttle 37 is thus displaced transversely carrying with it the striker arm 22. A tongue 38 on the arm which slides in a longitudinal slot 39 in the shuttle 37 is thus disengaged from a cross slot 58 in a stationary block 57 while at the same time one of the half-nuts 24 is engaged with one of the power screws 25 or 26. The power shift of the barrel 21 then takes place and the pinion 20 slides into mesh when it can, while the tongue 38 drops back into another locking cross slot 58 with the manual lever 48 returned. to its original position by springs 47. During the speed change, a main clutch between the driven shaft 19 and a tail shaft (not shown) is momentarily opened. This clutch is shown schematically at 55. Displacement of the lever 48 rocks geared twin shafts 53 in opposite directions and these by rocking four cams 54 thrust the disc 55 right to open the clutch.
