Abstract: 945,841. Cigarette-making machines. MOLINS MACHINE CO. Ltd., D W. MOLINS, and J. A. MASON. June 7, 1961 [June 8, 1960], No. 20093/60. Heading A2C. [Also in Division F2] A knife feeding device for a rotating cut-off of a cigarette machine has a frictionally gripped sickle knife that is fed outwards by the rotation of a screw in a nut, which nut has fixed to it a flexible member (e.g. a chain) attached to an abutment on the inner end of the knife. The knife 20 (Fig. 4), frictionally held between plates 24 and 25, and supported by a block 23, is drawn outwards against a pair of springs 52 by a chain 50 attached at one end to an eyebolt 29 and at the other end to a nut 54. A bevel gear 56, fixed to a screw 55, mates with another bevel gear 57 fixed to a shaft 58 which rotates within the cutter bearing shaft. By means of gearing (Fig. 5 not shown) the speeds of these two shafts are arranged to differ by a slight angular displacement per revolution, and hence turn the screw 55 at a rate proportional to the difference between these two speeds. A Geneva stop mechanism 69, 70, on the end of a shaft 68, engages when the nut 54 reaches the lower end of the screw 55 and causes an overload clutch in the gearing (Figs. 6, 9, 10 not shown) to break so stopping further rotation of the screw 55. In an alternative arrangement, the chain 50 guided around four pulleys is attached to both ends of the nut 54 and to both ends of an abutment that replaces the block 23, this abutment having a small lug that enters a slot in the inner end of the knife 20. In another embodiment, the chain 50 is passed through the centre of the cutter bearing shaft, around pulleys 37 and 38 (Fig. 2) and is fixed to a slideable plate structure 39 in which a nut 44 is held captive. A screw 43 is driven by the machine drive via gearing within the box 11, a chain 47 and sprocket wheels 46 and 48 and a reduction gear 100. Specification 324,379 is referred to.

Abstract: 866,243. Cutting tobacco. MASON, J. A., and MOLINS MACHINE CO. Ltd. May 25, 1959 [May 27, 1958], No. 16878/59. Class 5(1). [Also in Group XXX] Downwardly converging conveyer bands 4 form a shoot leading to a tobacco leaf cutter, the shoot containing a feeler 15 to switch off the conveyers when the shoot is full. Leaf tobacco fed in at a higher (floor) level to a shoot 1 of converging conveyer bands 4 passes to a mouthpiece 3 where a lawn mower type of cutter 6 shreds it and passes to a discharge plate 10 or a conveyer 11. In Fig. 2 the leaves pass from conveyer 12 to a sloping conveyer 13 from which they fall to a conveyer band shoot 14 provided with a pivoted feeler 15 which rises when full to operate a mercury switch to rotate a packing paddle wheel 16 which, when automatically reversed when the shoot is full, passes the leaves to a second shoot 20 and so on to other shoots and cutters. The band conveyer 4, Fig. 5 may be urged by spring 33A to compress the leaves in the shoot. The cutter may be kept sharp by a rotated grinding wheel traversed along the cutter by a crank 27, Fig. 4 (not shown). Specification 588,129 is referred to.

Abstract: 749,843. Sharpening machine cutters in situ. MOLINS, D. W., SMITHG., MASON, J. A. RUAU, F. F., and MOLINS MACHINE CO., Ltd. June 21, 1954 [June 25, 1953], No. 17660/53. Class 60. In a tobacco cutting machine of the kind in which knives 1 having straight cutting edges and projecting through a rotating cutter disc of head 2 move in a plane and sweep across a mouth 3 through which a cheese of compressed tobacco leaves is fed and cut thin slices from the end of the cheese, the cutting plane of the knives is tangential to the curved surface of a grinding wheel which surface is so located with respect to the path of the knives and their orientation with respect to the axis of rotation of the cutter..head that successive points along a knife edge making grinding contact with the wheel along a straight line. The grinding wheel 4, which protrudes slightly through an aperture 6 in a plate 5 flush with the front of the machine frame, is rotatably supported in a frame 7 pivoted, on a tubular shaft 8 to the machine frame 9. The wheel 4 is held between, a tapered upper stub staft 14 driven by an electric -motor 15, and a tapered lower stub shaft 16 journalled in a slidable bush 19 having a rack 20 engaged by a pinion 21 operable by a handle 24; a locking quadrant 25 is provided. A key 18 ensures rotation of the wheel. The wheel 4 is trimmed by a diamond 26 mounted in a holder 27 part of which consists of a screwed rod 28 threaded into a carriage 32 which is traversed to and fro parallel to the wheel by a long screw 33 journalled in the frame 7 and driven through an Oldham coupling 36 by an electric motor supported on a bracket 35. The carriage 32 carries rollers 56 which run on guides 57, 58 to prevent it from rotating; alternatively the nut may be guided by a fixed rod parallel to the screw. When trimming of the wheel is required, the motor driving the screw 33 is started either by manual switching or by a clock-controlled switch. The carriage 32 then moves upwards, the diamond traversing the length of the wheel,until an abutment 37 fixed to the carriage strikes a push rod 38 to operate a micro switch 39 so reversing the motor for a downward traverse of the diamond. As the diamond reaches the top of its stroke, a bevelled face 37A of the abutment 37 moves a pin 40 to cause advance of the wheel. The pin 40 is fixed to a ring 43 on which is pivoted a pawl 42 urged by a spring 44 into engagement with a ratchet wheel 41 fixed to a nut 13. The nut is rotatably mounted in a bracket 7A pivoted at 7B in the frame 7; a screw 10 fixed to a sleeve 11 pivoted on a fixed shaft 12 is threaded into the nut. As the diamond goes down again, the pin 40 is released and the ring 43 is returned by a spring 45. At the back of the ratchet hub 41 is a gear wheel 46 meshing with a gear wheel 47; the latter may be rotated by a roller 48 so as to screw the nut 13 back fully on the screw 10 when a new grinding wheel is fitted; an indicator may be fitted to the collar to show the amount of useful wheel left. As the diamond approaches the end of the downward traverse and is clear of the wheel 4, a pawl 31 is operated to cause in-feed of the diamond. The pawl is pivoted on a rocking quadrant 49 pivoted on the diamond feed screw axis; a toe 50 on the quadrant strikes a bell crank lever 51 pivoted at 52. One arm 53 of the lever abuts a stop 54 while the other arm 55 is shaped as a sharp tooth adapted to engage the toe 50 and rotate the pawl quadrant; a spring holds the arm 53 against the stop 54. A spring detent device consisting of a double-armed lever pivoted at 63 engages by an arm 64 a serrated wheel 65 fixed to the ratchet wheel 30; the arm 66 is locked by a spring, so preventing accidental movement of the diamond holder 27. Dust and metal particles are removed by a suction duct 59 to which is attached a hood 60; auxiliary hood pieces 61, 62 are attached to the frame 7. The screws 28, 33 are protected from dust by bellows 29, 34. Specification 365,997 and 588,129 [Group I], are referred to.

Abstract: 703,319. Gun-loading mechanism. MOLINS, D. W., HAYSOM, J. C., MASON, J. A., and MOLINS MACHINE CO., Ltd. Jan. 1, 1952 [Oct. 3, 1950; Oct. 18, 1950; July 10, 1951], Nos. 24195/50, 25417/50 and 16377/51. Class 92(1) Apparatus tor loading ordnance comprises a projectile tray 2 and a charge 1 arranged side by side in the firing position, Fig. 2, aside and clear of the breech, and movable in convergent paths so that the tray 2 and later the tray 1 are moved into the ramming position. In the form shown the tray 1 is carried by an arm 3, Figs. 1 and 2, rotatable on bearings surrounding the recuperator casing 5 and is swung to and fro by a motor 6, Fig. 12, via worm 7, wormwheel 8, and linkwork 1, 10, 11. The tray 2 is pivoted at 15 to the tray 1 and is linked at 20 to an arm 22 which is pivoted at 23 to a bracket 24 secured to a non-recoiling part of the gun. By this means the tray 2 swings relatively to the tray 1 during rotation of the arm 3 to occupy the ramming position shown in Fig. 1. After the projectile has been rammed the arm 3 continues its clockwise rotation to bring the charge tray 1 into the ramming position. The arm 22 also carries cams 56, 57 which coact with a follower linked at 50, 51, 52 to a pivoted member 48 whose function is to prevent the projectile being thrown out of the tray during the swinging movement of the arm 33; in a modification the tray has two curved surfaces separated by a rib for-serving this purpose. The trays 1 and 2 are fitted with rammers 30, 25 respectively, the former being connected to a chain 31 and the latter to a cable 26 which are driven by an electric motor 32. The drive is such that the rammers move in opposite directions. The rammer 30 is pivotally mounted so that it may yield when passing rearwardly under the charge whilst the rammer 25 is ramming the projectile into the breech chamber. The projectile is guided during the ramming operation and prevented from moving backwards after having been rammed, by members 125, 128, on a tray 122 connected to a slide 123 which is reciprocated in suitably timed relation by a forked arm 140 as shown in Fig. 12, the slide being mounted on a rail 124 adjacent the breech ring. Fig. 11 (not shown) gives the circuit diagram for actuating and controlling the entire mechanism whereby once the trays have been loaded and a switch closed, the projectile tray is first brought into the ramming position, the projectile then rammed into position being guided by the guides on the tray 122 and being prevented from backward movement until the charge tray is swung into position, and the arm 3 with the trays returned to the initial position after the ramming of the charge. Specifications 578,622 and 703,320 are referred to. The first Provisional Specification refers to Specification 578,621.

Abstract: 689,580. Coating webs. MASON, J. A., and MOLINS MACHINE CO., Ltd. Feb. 13, 1951. [Feb. 14, 1950] No. 3763/50. Class 140. [Also in Groups XXIV and XXVIII] A rod, tube, or the like is locked in position in a holder in which it is slidably mounted by means of a transversely. slidable pin which is pressed into engagement with the rod, tube, or the like by a circlip passing around the holder and pin. The pin may have a hole through which the rod, tube, or the like passes. As shown, an adhesive-supplying tube 3, which is a sliding, fit in an orifice 1 in a nozzle 2 is locked in position in the nozzle by means of a pin 5 with a transverse hole 6 through which the tube passes. The pin is accommodated in a blind hole 4 transverse to the bore of the nozzle and is pressed into engagement with the tube 3 by a circlip 9 located in a groove around the nozzle. A spring 10 engaging a collar 11 on the tube may tend to eject the tube from the nozzle thereby facilitating adjustment when necessary to compensate for wear of the tube. The tube may be serrated, and the outer end of the pin 5 may have a threaded hole 8 to facilitate withdrawal. Specification 643,856 is. referred to.

Abstract: 643,856. Coating webs. MASON, J. A., and MOLINS MACHINE CO., Ltd. Jan. 10, 1947, No. 884. [Class 140] A device for applying a line of liquid, e.g. an adhesive to a paper strip comprises a vessel 1 connected by a tube 12 to a nozzle 16, an externally operable valve 18 controlling flow of liquid through the tube and a wire 11 extending through the tube which is caused by opening and closing movements of the valve to move lengthwise within the tube and nozzle. The device may be incorporated in an automatic wrapping machine such as upon a square bar 2 upon which it is transversely adjustable. Mounted on the device are pulleys 23, 24 over which the paper strip 7 passes in contact with the nozzle 16. The valve 18 is spring urged on to its seating formed by an enlargement 11 of the bore in a bushing 14 connecting the tube to the container, and is provided with a catch to hold it away from its seating to allow the free passage of liquid for the coating operation. The valve 18 is mounted in a cover-plate 25 of the container 1, the cover-plate also having a lid 21 covering an opening through which and through a filter 22 the container may be replenished. The wire 11 may be of such length that when the valve 18 is seated it projects through the nozzle 16. The valve 18 may comprise a screw-operated needle valve. The rate of flow of liquid may be varied by varying the relative sizes of orifice and wire, or by adjusting the height of the vessel above the nozzle. A tube 10 may be provided within tube 12 surrounding the wire 11 to prevent buckling. In a modification, not shown, the nozzle and tube move lengthwise of the wire, which is of sturdy construction, with the valve. The valve may be operated through cams and levers or an electromagnet, from the starting gear of the machine.

Abstract: 639,817. Control of motors; mechanical switches. MASON, J. A., and MOLINS MACHINE CO., Ltd. June 9, 1948, No. 15595. [Classes 38 (iii) and 38 (v)] [Also in Group XXIV] A switch control device, for use with dynamically-braked, electrically-driven machines comprising variable speed gearing for driving the machine, has means for adjusting the switch relatively to the cam or the like which operates it so as to vary the instant of disengagement of the contacts and initiation of dynamic braking in accordance with variations in the adjustment of the variable speed gearing. In a packet-wrapping machine the packets are moved by pusher-pieces 1 on a conveyer 2 which is driven by an electric motor 3. The motor is controlled by means of a timing- switch 4 which is adapted to initiate dynamic braking and to stop the machine in a predetermined position, as described in Specification 628,299. The motor drives pulleys 15 and 16, the latter being geared to the main shaft 21 of the conveyer. The member 15 comprises two separate parts (see Group XXIV) which are relatively movable to alter the effective diameter of the pulley, this adjustment being effected by means of a worm 29 coupled by flexible cable 30 to a movable knob or handle 31. The worm-shaft has a threaded portion co-operating with a nut which is coupled through bell-crank 34 and link 37 to a lever 12 which is fixed to a spindle of the switch 4. The switch comprises contacts 7, 8, which are mounted on switch body 9 and which co-operate with a plunger 6 coacting with a cam 5 driven from shaft 21. When the member 31 is moved to alter the speed of the machine, the switch body is correspondingly adjusted relatively to the cam 5 and the moment at which contacts 7, 8 are opened is determined by the speed at which the machine is running. The lever 12 may be in the form of a quadrant to allow for adjustment to compensate for different operating conditions. A belt 25 is held taut during adjustment of the variable speed drive by means of a spring 39 and quadrant 20. The pulley 16 may be slidable in splines in order to align the belt correctly.

Abstract: 639,377. Wrapping machines. MASON; J. A., and MOLINS MACHINE CO., Ltd. July 22, 1948, No. 19653. [Class 94(i)] [Also in Group XXIV] In a wrapping machine in which a web of wrapping material 33 is fed downwardly across the path of articles on a conveyer 2 by means of a feed roller 37 actuated by a train of gears driven from the conveyer driving mechanism, the gearing being such the web is moved slowly while being severed by cutters 31, 32 and more rapidly at other times, the feed roller gear train is coupled to the conveyer driving mechanism by skew gearing 10, 11 and 13 having one gear axially translatable along another, whereby the timing of the gear train and conveyer driving mechanism may be varied. As shown, the gear 13 is axially adjustable by means of a screw 16 and nut 15 along a splined shaft 14 which drives a crank disc 18 having a diametral slot 19 in which is secured a crank pin 20 carrying a gear 21, the eccentricity of the pin being adjustable by a screw 40. The gear 21 meshes with an idler gear 22 which in turn meshes with a gear 24 which is rotatable on an extension of the drive shaft 8 of the gear 10 and drives the feed roller 37 and cutter 31 through spur and bevel gearing, the gears 21, 22 and 24 being maintained in rolling contact as the crank disc rotates by links 23 and 25. As a result of an adjustment of the pin 20 to alter the ratio between the high and low speeds of the feed roller, the timing of the machine is disturbed, and this may be corrected easily by rotation of the screw 16 by a knob 38.
