Title: Locking devices for screw threaded members
IPC: F16B39/24
Filed: 1938-05-19
Abstract: 514,923. Locking devices for screw-threaded members; making locking washers. CHAPPUIS, J. A. May 19, 1938, No. 14992. Convention date, April 11. [Class 89 (i)] [Also in Group XXII] A locking device for screw-threaded members (bolt 1 and nut 2 on workpiece 3) comprises a pair of washers 4, 5 one of which has on one face one or more surfaces of substantially helical or inclined formation of greater inclination or pitch than, and of the same hand as, the inclination or pitch of the thread in or on the screwthreaded member, said surface or surfaces cooperating with one or more projections or helical or inclined surfaces on the second washer in such a manner that rotation of the first washer in the direction of unscrewing moves it in an axial direction a greater distance than the axial movement of the screw-threaded member produced by the same amount of rotational movement. The outer face of either or both washers may be smooth, roughened, or serrated as at 6, and the periphery of either or both washers may be of hexagonal or other non-circular form, or of circular form with flats or notches to facilitate unlocking. The washers may be made of metal which may be oxidised or nickel plated, synthetic resin, or other moulded material; they may be identically alike, and they may be coupled together by a thin central eyelet. Instead of being flat the two washers may be slightly conical so that they may be elastically deformed and flattened by the nut. Three hexagonal washers 27, Fig. 5, may be stamped simultaneously from a parallel-sided strip 24 by means of lateral punches 25 which stamp out notches from the sides of the strip, and punches 26 for the holes in the washers. The inclined surfaces and the serrations may be stamped simultaneously by placing the washer over a guide bolt 30, Fig. 7, at the centre of a toothed die 29 within a cavity 28 and then lowering the threepart punch shown in Fig. 6. The latter comprises an external portion 31 guiding a tube 32 which is formed on a part or the whole of its extremity with toothing 38, the tube 32 being pressed upon by a tube 33 and caused to make a small rotation by means of inclined planes 34, 35, such rotation being limited by a lug 37.

Charges, agitating.-A mechanically-operated reciprocating poker for gas producers &c. which is mounted and operated independently of the producer plant, is arranged so that its inclination with respect to the axis of the producer can be varied when the poker is clear of the fuel bed. As shown in connection with a producer having a fixed top 3 and a rotary shell 1, the poker 5 is carried by a cross-head 10 on the piston-rod of a double-acting cylinder 7 the valves of which are automatically operated by the engagement of an arm 12 on the cross-head with stops 15, 16 on a sliding rod 13, the cylinder being supported by rollers 24, 25 in guideways 29, 26 so arranged than an extension of the axis of the cylinder will always pass through the poke-hole 4. The downward movement of the cylinder along the guideways is controlled by ratchet levers, a brake, or, as shown, by gripping- shoes 33 acting on a bar 31 extending between the guideways from a yoke 22 on the cylinder. The shoes may be operated by a hand lever 34 or by solenoids. The return movement of the cylinder is effected by a cylinder 35 and piston 36, to a cross-head 33 on the rod of which are connected cables 44 passing round pulleys 42 and secured at their other ends to the yoke 22 on the cylinder.

Abstract: 757,374. Ice-cream. ROSE BROS. (GAINSBOROUGH), Ltd. April 22, 1955 [May 25, 1954], No. 15318/54. Class 28(1). [Also in Group XVII] In a machine in which portions of ice-cream or other plastic edible material are enclosed in succession in a folded web which is collapsed and secured between adjacent portions, a strip of the plastic material is continuously extruded towards the web and severed at intervals in timed relationship with the movement of the web so as to deposit thereon a succession of portions and a stick of wood or stiff cardboard is inserted laterally into the extruding strip before severing operation. Blocks 1 are severed in succession from a strip 2 of ice-cream extruding from a nozzle 3 and deposited on a web 12 of heat-sealable wrapping material which is then folded around the blocks in the form of a tube, the severing and wrapping mechanisms being constructed as described in Specification 743,978 [Group XVII]. A stick magazine 17 is slidably mounted on rollers 18 in a framework 19 and is movable towards and away from a suction device 21 by a spring-loaded two-armed lever 22, 23 actuated by a cam 24 on a main shaft 25. The device 21 is rotated intermittently to carry suction nozzles 29 in succession into register with the mouth of the magazine so that each receives a stick 31 and withdraws it against the action of retaining springs 38, a trapping member 32 being oscillated in synchronism with the movements of the magazine, through linkage operated by a cam 37 on the shaft 25, to prevent movement of the remaining sticks. Each stick is deposited by the nozzles in a channel 39 and its leading end is gripped by the first of two pairs of knurled rollers 41 and 42 mounted on a carriage 43 which is secured to a slide bar 44 reciprocable in a slideway 46 by a cam 48 on the shaft 25. The upper rollers are carried by spring- loaded pivoted arms 45 and coupled to the lower rollers by gears 49, the latter being driven by sprockets 51 coupled by a chain 52 to a sprocket 53 which is mounted in a bearing bracket 54 carried by the framework 19 and driven by gearing 56, 57 from the shaft 25. The rollers and carriage co-operate to feed the stick along a supporting channel 58 and drive it into the extruding strip 2 through an aperture in the nozzle 3.

Abstract: 621,051. Impact pulverizers. BALLS, D. W. May 21, 1946, No. 15357. [Class 59] In impact pulverizers of the type comprising an outer casing enclosing a milling chamber having a perforated circumferential wall spaced from the inner surface of the casing, the material to be milled is delivered to the chamber through an inlet disposed in alignment or substantially in alignment with the axis of rotation of the hammers or beaters, and the milled material is expelled through the perforated wall in a substantially radial direction and thereafter delivered to a discharge outlet by the action of an air stream which is caused to flow over the whole of the perforated wall in a direction parallel to the outer surface thereof. The mill shown comprises an outer casing 10 having a detachable cover plate 12, a fan casing 21 formed with a tangential discharge outlet 23, and a milling chamber 16 in which revolve beaters 26 mounted on a shaft 24 which also carries an exhauster fan 22. The chamber 16 is defined by a disc 15 with a central feed aperture 18 which is carried by the cover plate, a disc 29 secured to stream-lined projections 30 on the casing, and a circumferential perforated screen 31. The plate 12 is formed with air inlets 14, the size of which is adjustable by rotating an apertured disc 19 mounted on a boss 17 of the disc 15. Ingress of dust, &c. to the shaft bearings 27, 28 is prevented by seals 32, 33. The casing 21 is adjustable on the casing 10 so that the outlet 23 may be positioned horizontally, vertically or at an angle. The plate 12 and disc 15 are removable as a unit to enable the screen 31 to be exchanged for one of coarser or finer mesh.
