Filed: 1943-08-20
Abstract: 569,946. Grinding, flung, &c. tools. FLORACK, J. G. Aug. 20, 1943, No. 13600. [Class 60] [Also in Group XXII] A rotary grinding, sand - ing or filing tool comprises a shaft 1 having thereon a boss 2 against which abut a disc 4 and a back plate 5, the outer end of the shaft being threaded at 3 to receive a nut 10. On the threaded part is placed a tapered rubber core 6 which may have peripheral grooves and ridges, screws 7 holding the parts 4-6 together, and on the free end of the shaft is placed a disc 8 and a back plate 9 ; when the nut 10 is screwed up the core is compressed by discs 5, 8 and expands inwardly and outwardly. Mounted on the core is a cylindrical sleeve built up of several layers, namely, a layer 11 of flexible glass, a layer 12 of cardboard, a layer, 14 of paper or cloth coated with fine emery, whilst a further layer 15 of paper or cloth coated with coarse emery or carborundum may be provided. The circumferential ends of the various layers overlap, and those of one layer are staggered with respect to those of adjoining layers, and surrounding one end of the sleeve is a narrow metal band 16. The nut 10 is tightened so that the larger end of the core expands within the sleeve to hold this firmly against the band 16, leaving the outer part of the sleeve free of the core, so that it may yield in contact with the work ; when the abrading-surface is worn, the worn layer can be reversed with the worn part. under the band 16. In order to grip the abrading-surface, the band 16 may have a roughened inner surface, which may be formed by prick marks. The operative layer of the sleeve may comprise a flexible steel strap file, this being backed by a rubber layer, and other inner layers as described above. The core may consist of an expanding metal mandrel.

Title: Improvements in Automatic Toy Pistols.
Inventor: WHITE ALFRED ERNEST
IPC: A63H5/04
Filed: 1916-09-27
Abstract: 103,280. White, A. E., (Upton Machine Co.). Sept. 27, 1916. Pistols fitted with detonating devices.-Relates to automatic toy pistons of the pneumatic type in which a sharp report is produced by the rupture of a strip of paper or other frangible material caused by a sudden impact of air which is compressed within a chamber by a spring-actuated plunger operated by trigger mechanism, and consists of means actuated by the trigger mechanism for automatically advancing and clamping the paper above the opening in the compression cylinder, the clamping operation preferably taking place substantially simultaneously with the releasing of the trigger mechanism. The piston of the cylinder 15 is operated by the forward arm 26 of a member 23, which is mounted on a pivot 25 and has its rear arm 27 connected to a spring 28. A release member 24 arranged transversely to the member 23 has an enlarged and substantially triangular aperture 37 through which the pin 25 passes. When the trigger 31 is pulled, the two members 23, 24 turn together on the pin 25 until a projection 38 on the member 24 engages a: lug 39 on the casing 10, when the member 24 moves downwards on the pin 25 and disengages the lug 35 from the notch 36, thereby releasing the member 23. The wheel 48, which feeds the strip 40 of paper from a roll 41, is operated by the hooked end 53 of a bar 52, which is pivoted at its other end 52<a> to the member 24 and pressed towards the wheel by a spring. 54. To prevent the paper from being injured by the blades 50 of the feedwheel, it is yieldingly engaged by a flexible metal strip 51 as it passes over the wheel. During the upward movement of the piston, the strip 40 is clamped on the end of the cylinder 15 by a flexible plate 43, which is drawn down by a link 46 when the member 24 moves downwards. The plate 43 has an opening registering with the opening in the end of the cylinder and with the opening 17 in the flange 14 of the casing 10.

Abstract: 201,301. Minton, O. May, 16, 1922. Coating and impregnating materials in long lengths.-Coating and impregnating apparatus is combined with a liquid-sealed vacuum drying chamber. The web 1, for example of paper, passes through a mercury seal 4, round rollers 29 immersed in heated mercury, then through a bath 7 of the liquid with which the web is to be treated, round more drying rollers 29, and then out of the evacuated chamber 25 by way of the second liquid seal 4 to a winding-up spool 19. The bath 7 may alternatively be located at the entrance or exit of the chamber, and the drying means may take other forms such as heated cylinders or electric heaters between suspended loops of the material.

Title: Improvements in or relating to packing machinery
IPC: B65B19/14
Filed: 1933-05-12
Abstract: 411,668. Closing mouths of cartons. JACKSON, D., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. May 12, 1933, No. 13831. [Class 94 (i).] In a machine for packing cigarettes in a U-shaped block-ended packet 1 the open end of which is closed by a flap 4 engaging in a slit 16 in one face of the packet, the filled packets are conveyed by moving bands 3 along a drying or other channel 2 in an upright position with the flaps 4 projecting upwardly and are fed laterally in succession by a reciprocating plunger 7 into a folder box 5, 6 where the flaps are folded downwardly and inserted in the slits 16, after which the finished packets are ejected by a plunger 20 into a stacker 26. The foremost packet is withdrawn from the channel 2 by a suction member 8 which protrudes through a slot in the plunger 7, the latter being pivoted at 117 so that it is moved to the left (Fig. 1) out of its path while it is being retracted. The forward movement of the plunger 7 moves the packet to a position between the walls 5, 6, whereupon an oscillating member 10 folds the flap 4 about a triangular bar 13 to break the score lines, the flap being retained by a spring plate 14. The packet is then moved to a further position by the introduction of a second packet into the folder box. The stroke of the plunger 7 is slightly greater than is necessary, and the extra movement causes the lower part of the packet to bulge into a recess 23 in the wall 6, while a guide 15 presses the flap 4 inwardly against the portion 17 of the packet just above the slit 16. An oscillating member 22 now presses the flap into the slit, the flap being pressed inwardly by an extension 21 of the plunger 20. The introduction of a third packet into the folder box advances the first packet to a position from which it is ejected into the stacker 26 by the next operation of the plunger 20. The members 10, 22 are mounted on the same shaft 11 and operate simultaneously on adjacent packets.

Electrodes 75, 76 of the material to be plated are secured to the ends of the conductors. An arc discharge between the electrodes is initiated by a trigger electrode, not shown, and causes portions of the electrodes to be vapourized. The magnetic field set up by the current in the conductor 77 behind the gap between the electrodes causes the vapours to be blown away from the gap on to the article to be plated.
