Title: Improvements in cigarette making machinery
IPC: A24C5/28
Filed: 1927-06-27
Abstract: 299,736. Imperial Tobacco Co. (of Great Britain & Ireland), Ltd., and Coates, A., F. June 27, 1927. Cigarette-making machines. - In a cut-off mechanism for severing a continuously moving cigarette-rod into lengths, a knife, or a carrier for a rotary knife, is given a bodily movement in a plane inclined to the cigarette rod but is prevented from having any rotary movement. In one form, Figs. 1 and 2, the knife 30 is mounted on a coupling element 14 connecting crank arms 10, 11 on two rotating cranked shafts 6, 7 which are out of square with the knife. The knife is clamped to an extension piece 27 adjustably secured to a stud 26 on the element 14, so that the knife can be set square with the cigarette rod. The shafts 6, 7 rotate in bearings 8, 9 in the vertical portion 5 of a frame 3 mounted on the bed-plate 2 and adjustable about the driving- shaft 1 in order to provide for cutting cigarettes of different lengths. The cigarette rod 48 passes through guides 32, 33 on a ledger element 31 sliding on horizontal bars 35 and reciprocated from the shaft 1 by means of a crank disc 41 and connecting-rod 40. Grinding discs 45, 46 are loosely mounted on the element 31 and act on opposite sides of the knife. The bearing 47 for the grinding disc 46 can be adjusted about a vertical axis. In a modification, Fig. 5, a rotary knife 61 is carried bv an arm 57 having a forked end pivotally secured to a vertical axle 51 on the coupling element 14. The knife is driven by a belt 67 passing over a pulley 62 on the knife spindle 50 and a, pulley 63 driven by a gear wheel 64 rotatable on the coupling element 14 and meshing with a stationary gear wheel 65. The belt passes over jockey rollers 55 on an axle 54 carried by arms 52 on the axle 51. In a further form, the plate 5, in which are mounted the cranked shafts 6, 7, is fixed to the bed-plata, and the coupling element 14 has an extension 70, Fig. 10, at right angles to the cigarette rod. A bearing for the spindle 60 of the rotary knife 61 is adjustable in a slot 71 in the extension 70. This adjustment causes the cutting to take place at a different part of the circular movement of the coupling element 14, and the cutting preferably takes place at a time when the speed of the knife in the direction of the cigarette rod is increasing. Means may be provided for adjusting the axis of the knife in a direction transverse to the slot 71 in order to compensate for wear. The knife is driven by a belt passing over a pulley on one of the cranked shafts and over jockey rollers on the coupling element 14. A non-circular rotary knife, for instance a radial knife secured to the spindle 60, may be employed, the belt drive being replaced by positive gearing. The Provisional Specification states also that a ledger plate may be constituted by an endless chain, the links of which are grooved to support the cigarette rod and slotted for the passage of the knife, sharpening means for the knife being provided by a continuation of the walls of the slots.

IPC: B23D3/02
Filed: 1951-07-20
Abstract: 686,895. Machine-tool details. NUTS & BOLTS (DARLASTON), Ltd. July 20, 1951, No. 17233/51. Class 83 (iii). A machine for cutting a groove in a hollow article such as a V-groove in a nut using two tools inserted into the article from opposite ends comprises a starting control which causes (a) fluid-pressure means to advance the tool holders until the tools are fully within the article, (b) operation of a dashpot to control the speed of movement of the tool holders, as the tools begin to cut the groove, to provide an appropriate feed and (c) reversal of valve means on completion of the cut so that the fluidpressure means withdraw the tool holders and return the dashpot to its initial position. The slide 15, which controls the movements of the tool-holders, carries a rack 14 engaged by a pinion 13 secured to a shaft 12 on which a further pinion 11 is fast, the latter engaging a rack on a plunger rod 19 of a fluid-pressure piston and cylinder actuating device 18, 17. A handle 21 is moved to operate a control valve 22 to admit pressure fluid from line 23 to the lower end of cylinder 17 to raise the piston and thus move the slide 15 in the working direction to the left as shown. The pinion 11 also engages a rack 27 which is connected through a lostmotion beam arrangement 29, 30, to a dashpot piston-rod 34. As the slide moves quickly to the left'in its non-cutting movement the rack 27 moves downwardly until finally the lower end 32 contacts the upper part 33 of beam 28. The dashpot then operates to slow the motion during the cutting operation of the tools, an adjustable valve 37 controlling the leak from the lower to the upper end of cylinder 36 and thus regulating the speed of movement of the tools. At the end of the cutting operation the upper end 39 of the rack 20 contacts the plunger 40 of a valve which directs pressure fluid to return the starting handle to its off position which reverses the direction of movement of piston 18 returning the parts to the initial position shown. Specification 291,478, [Class 83 (iii)], is referred to.

Filed: 1929-06-06
Abstract: 336,202. Czarny, M., and Frolander, F. C. June 6, 1929. Recovering waste lubricants.- Lubricating oil is reconditioned by abstracting the lighter fluid impurities by a. wick, and evaporating such impurities from the wick. For example, oil is pumped continuously from the crank-case of an internal combustion engine to a pipe 13, and a container 18; it passes through a filter bag 24, preferably formed of coarse outer and fine inner cloth, to an outlet 21, a pipe 16, and a sump cup 30 into which dips the lower end of a cotton-cloth or other vertical wick 33 compressed at its upper end between a nut 36 and the tube 31. The gasolene and water are absorbed by the wick 33 more readily than is the oil, and rise past the constriction to the divided and spread out ends S of the wick from which they are evaporated by the warm air within the engine hood passing under the cover 35. The oil returns by the pipe 17 to the engine. In modifications the filter and the evaporating unit are combined, the wick column being arranged in the bag 24; the wick may then be quite short. In the modification shown in Fig. 6 the oil is pumped from the crankcase of an internal-combustion engine through a pipe. 113, is filtered through a bag 132, and returned through pipes 128, 130; gasolene water, and the lighter portion of the lubricating oil are withdrawn by a wick 139 which is compressed adjustably by a nut 141 to permit and control the passage of oil. The oil is then evaporated along with the gasolene and water from the ends S of the wick within a chamber 125 by air drawn through a ball-inlet valve 153, an opening 150 regulated by a screw 152, and a passage 149, and is carried to the manifold, carburettor, or an air-cleaner in front of the carburettor, through a bore 147 and a pipe 148, whereby the cylinder &c. is lubricated. The wick may also be compressed adjustably at its lower end.
