Title: Improvements relating to machines for cleaning cotton, cotton waste and like fibrousmaterials
IPC: D01G9/00
Filed: 1923-12-06
Abstract: 229,787. Wild, Ltd., F. & A., and Quinn, F. Dec. 6, 1923. Cleaners &c.-In machines of the type in which the cotton &c. is treated by a saw-toothed roller and drawn up a suction shoot to a perforated cage the material is withdrawn from the cage, subjected to treatment by a second sawtoothed roller, and returned to another portion of the cage, from which it is finally delivered. The. material is fed to the, roller c which co-operates with a knife d or knives and is passed up the shoot e to the cage f as described in Specification 218,877. The fibres collected on the cage are removed by rollers u and acted on by a second roller m, which co-operates with a knife n and delivers them along a shoot o to a portion f<2> of the cage. They are finally delivered at the point r. The dirt &c. separated by the knife n may be removed by a worm-conveyer w. A stripping- roller s, which may be intermittent in its action, acts on the roller c and delivers the dirt &c. on to a travelling band t. According to the Provisional Specification, the second roller may deliver the treated fibres to a second independent perforated cage.

Title: Pencil-type gas lighters
IPC: F23Q2/16
Filed: 1975-07-23
Abstract: 1475625 Gas lighters KOJIMA PRECISION PARTS CO Ltd 23 July 1975 [19 Aug 1974 22 Feb 1975 (2) 22 March 1975 (2) 23 March 1975 (4)] 30771/75 Heading F4F A pencil-type gas lighter comprises a gas reservoir 6 Figs. 5, 6, communicating with an ignition nozzle 11 and high voltage generating means 47, the casing of the lighter being formed of two separable cylinders 2, 3, and the reservoir being adapted to be filled by a feed valve 20. An eccentric flame port 4 and an air vent 5 are provided in cylinder 2, and nozzle 11 is formed on the stem 12 of a gas valve 10 urged by a spring 13 against a valve seat 14, which latter carries a hollow piston 17, and a pressure-reducing- packing 16. The piston is connected to one end of a conduit 22 provided with pores 24 opening into gas reservoir 6, the other end of the conduit being connected to the housing 21 of feed valve 20. The compression of packing 16, and thereby the volume of gas emitted from nozzle 11 can be varied by rotating housing 21 by means of a screw-driver slot 23. A discharge electrode 25 is connected to high voltage generating means 47 by lead wires 31, 54, and means 47 comprises a charging and discharging circuit formed by a battery 48, a capacitor 49, a transformer 50, and a microswitch 51, and the latter is actuated by a lever 60 Fig. 11. When the cylinders 2, 3 are pulled in opposite directions a dowel 57 oppose movement of reservoir 6 to allow a flame to be produced, but with increasing force the cylinders can be separated to thus expose valve 20 so that reservoir 6 can be filled. When cylinder 2 is pushed upwardly against spring 37 Fig. 8, relative to reservoir 6 and cylinder 3, a plate 32 engages a collar 39 on nozzle 11 and raises valve stem 12 to open valve 10 and allow gas to pass from reservoir 6 through piston 17, packing 16, and through stem 12; the gas being then ignited. In a modification, a pipe 62 Fig. 13 connects valve opening plate 32 and a ring 64, which latter is moved axially relative to cylinder 2 to open valve 10, and to actuate microswitch 51. In a further modification, the coupling of the cylinders 2 and 3 includes a sleeve 72 Fig. 17, having a short groove 74 which co-operates with a lever 79 fixed to a ring 78 when lifting valve 10; the lever co-operating with a longer groove 75 after rotating cylinder 2, when it is required to separate the ends of cylinders 2, 3, as valve (82) Fig. 33 (not shown) is used for filling the reservoir. In another modification, sleeve (72<SP>1</SP>) has only a single slot (75) Fig. 26 (not shown). Valve 10 may be lifted by a cam (92) Fig. 27 or Fig. 28 (not shown).

Abstract: 647,870. Mining-machines. ANDERSON, A., and ANDERSON, BOYES & CO., Ltd. Nov. 29, 1948, No. 30881. [Class 68 (i)] A machine for mining mineral is provided at floor level with undercutting means such as an endless chain cutter 10 or a reciprocatory bar cutter, and positioned above this undercutting means are two sets of rotary cutting wheels 12, 13, each set being spaced along a driven shaft 14, 15. The shaft 15 is carried by a pivoted arm 21 mounted on the machine and is thus adjustably positioned above the shaft 14 so as to allow for the variation in the height of the seam. As the peripheral picks of each cutting wheel cut in the mineral during the advance of the machine, upstanding ridges are left between the wheels and these ridges are broken down by laterally projecting picks or wedge elements on the wheels located radially inwards from their peripheries. The comminuted mineral is carried to the face conveyer by a screw conveyer 16 or by a pair of screw conveyers mounted parallel to one another.

Abstract: 174,735. Gilmore, H. J. Nov. 2, 1920. Signature gatherers; sheet separators and carriers; pile tables; grippers and gripper mechanism.-Apparatus for gathering folded sheets and feeding them to a stitching-machine, or for folding single sheets to a printing or folding-machine, comprises one or more pile tables A each associated with a feeding-arm F and a gripper B for transferring the top sheet of the pile to a conveyer D. In the apparatus shown, the sets of feeding-arms and grippers are operated by a common rock-shaft M, the grippers being carried by rods N, and the feeding-arms being mounted in rooking guides F<2> and connected by chains F' to arms L on the rock-shaft. The grippers are provided with one or more spring-pressed pivoted jaws B<1> having cams P for engaging rollers or abutments R. J. The tables A are inclined and spring-supported, and the feeding-arms have rubbers G engaging the top sheet. When the grippers move forwards, the jaws are opened by the abutments R, and the rubbers push the top sheet of each pile into the jaws. During the rearward movement of the grippers, the jaws close and pass the folded sheets over shoes I which open the sheets; the abutments J thereupon open the jaws, and the sheets drop on to the conveyer. The shoes are carried by rods N<2>, which are pivoted at M' and are in the path of projections N<1> on the rods N. The rubbers G descend during the rearwards movement of the grippers, and move the underlying sheet into contact with registering- stops H. The conveyer works in a trough C, formed beyond the stitching-machine with a narrowed part for closing the stitched sheets. The trcugh is provided with registering-stops K, and the conveyer is preferably provided with registering-spikes. The trough may be replaced by a saddle.
