Filed: 1930-11-24
Abstract: 367,806. C e n t r i f u g a l machines. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Whirldry Corporation ; 125, Munson Street, New Haven, Connecticut, U.S.A.) Nov. 24, 1930, No. 35341. [Class 23.] A washing and drying machine comprises a perforated receptacle 7, Fig. 1, mounted within a stationary casing 1 and provided with means for selectively clutching it to an oscillating hollow vertical-shaft 58 for washing or to a rotating solid shaft 57, concentric with the hollow shaft, for centrifuging. The casing is provided with a depending flange 4 which encloses the motor casing 5 and the gear box 6 and is provided with rubber plugs 23 spaced at intervals around its lower periphery. A U-shaped bracket 31 is secured to the motor casing and is pivoted to the limbs of an inverted U-shaped bracket secured to the underside of the bottom of the casing 1 whereby the motor can be swung, to adjust the tension on the belt 48 which transmits the drive to a worm shaft 32, by the engagement with the motor casing of an insulating plug 51 in the head of a bolt 49 which works in a fixed bracket 50 and is provided with a lock-nut 52. An insulating layer 35 is inserted between the motor casing and the underside of the bracket 31 and the screws 36 are provided with insulating washers and pass through insulated bushes in the bracket 31. The worm shaft 76, Fig. 8, drives the vertical solid shaft 57 by the direct engagement of worm 79 and worm wheel 64, and oscillates the hollow shaft 58 by the engagement, with a toothed quadrant 71 thereon, of a rack 132 which is reciprocated along a stationary guide 97. Movement of the rack is effected by the engagement, with a pair of lugs 133 depending therefrom, of an eccentric 93 carried by a vertical shaft 85 which is driven by the worm gear 80, 81 from the shaft 76. The upper ends of the shafts 57, 58 are formed each with a ring of axial keys 114, 111, Fig. 4, and a tubular member 107, to the lower end of which the bottom plate of the receptacle 7 is secured, is formed with a plug 115 having axial keys 115a spaced around a central aperture. In the position shown in Fig. 4, the keys 111 are engaged by the keys 115a so that the receptacle is oscillated, and a spring-pressed ring 116 engages the upper ends of the keys 111 so that the ring is held out of contact with the cap-like upper end of the solid shaft 57. The ring may be released by pressing it inwardly against the spring 118 so that the tubular member 107 and clothes receptacle may be slightly raised to the position shown in Fig. 5 wherein the keys 115a engage the keys 114 on the solid shaft and the receptacle is rotated. Rings 122, Fig. 4, and 123, Fig. 1, prevent water from passing into the gear-box and a washer is fitted around the hollow shaft within the gearbox to prevent oil from reaching the clothes.

Poly(methylenenaphthylene) resins in the form of free-flowing powders, infusible below 350 C., are prepared by (a) dissolving a naphthalene in a solvent at a temperature below ambient temperature, (b) adding to this solution a second component, (c) adding a third component in increments, (d) allowing the temperature to rise, but not above 60 C., and (e) isolating the resin so formed, the solvent being capable of dissolving all the reactants but not the polymer, one of the second and third components being formaldehyde and the other being a condensation catalyst. The naphthalene may have up to 4 alkyl substituents each of up to 12 carbon atoms providing that at least 2 alpha-positions are available for reaction. The solvent may be a halogenated hydrocarbon. Step (a) may be performed at - 15 to + 10 C. and the solution allowed to warm up to ambient temperature before addition of the second component. The product may be filtered off and washed with water and alcohol. It may be sulphonated with conc. sulphuric acid at 100 to 150 C. and the product when washed and dried is useful as a cation-exchange resin, e.g. in water deionization. In typical Example I naphthalene in chloroform is condensed with methylol in the presence of cone. sulphuric acid. The product is poured into water, the chloroform distilled off on a steam bath, the water decanted off, the product titurated with ethanol and filtered off. In Example II the product was isolated by extraction with benzene. In Example IV the product was sulphonated and the sulphonation product poured on to crushed ice to isolate it.

For a press, drilling, grinding, slotting, shaping or re-assembling machine, a rotary indexing device comprises a wheel 3 carrying two circular tracks 16, 17 of stops and a radially movable stop for engaging stops on alternate tracks. The wheel is rotated by a bar 4 reciprocated by fluid-pressure means 12 against a dash-pot 13 and having racks 5, 6 thereon which are alternately engaged with a pinion 7 by blocks 8, 9 moved transversely by fluidpressure means 10, 11. The stop 18 is clamped on the block 9 by a screw 19. When the block 9 is moved to disengage the stop 18 from a stop 20, the rack 6 is engaged with the pinion 2. When the bar 4 is moved, the following stop 21 is moved against the stop 18. Some of the stops may be of greater height than others so that by adjusting the stop 18 only the higher stops may be engaged. In a modification, the racks and pinion 2 are replaced by friction gearing and the blocks 8 and 9 are moved by a single piston.
