摘要： 685,761. Cigarette-making machines. MOLINS, D. W., RUAU, F. F., JACKSON, N. W., and MOLINS MACHINE CO., Ltd. May 18, 1950 [June 2, 1949; Sept. 22, 1949], Nos. 14835/49 and 24417/49. Class 130. In a machine making a continuous composite rod of tobacco filler lengths T and stubs S from an unwrapped tobacco stream interrupted at intervals by the feeding of the stubs thereto, tobacco in the leading end part of each separated filler length is positively engaged and accelerated so as to cause it to move forward faster than tobacco behind it in the length. Tobacco showered from a hopper (not shown) onto an endless moving band 2 passes through a guide tube 3 and into and through a flute of a fluted drum 4 which is intermittently rotated to cut sections from the tobacco stream and replace them by stubs S delivered into the drum flutes as from a vertical shoot 5, the composite rod thus formed passing through a further guide tube 6' onto a paper web 19 moving more slowly than the band 2 and which carries the rod beneath a tongue 7 to the usual gumming and folding devices (not shown) of a continuous rod cigarette-making machine, the wrapped rod being later divided into mouthpiece cigarettes by cutting it through the middle of the stubs and tobacco lengths. An arm 15 pivoted both on a rotary disc 14 and, by a link 17, to a fixed point 18, has finger portions 12, 13, which may be 16 mm. apart, moving in the paths indicated by chained lines so as to enter, through a slot in the tongue 7, the leading end of each length T as it passes under the tongue. The leading finger 12 enters the path of the tobacco about 5 mm. behind a stub, and thereafter moves faster than the web 19 so as to act in the manner of the invention and tend to cause both closer abutment between the relevant length T and the preceding stub S and the reduction of any inhomogeneity which may have been caused by compression of the leading end of the length T as during cutting. According to the first Provisional Specification, the finger 12 enters the path of the tobacco 3 mm, behind a stub, and, according to the second Provisional Specification, it enters about 8 mm. behind a stub. Specifications 430,742, 669,557 and 669,559 are referred to.

摘要： 612,303. Grinding machine cutters. RUAU, F. F., and MOLINS MACHINE CO., Ltd. May 23, 1946, No. 15701. [Class 60] In apparatus for grinding a rotating and axially-moving knife having a cutting edge eccentric to the axis of rotation, e.g. the knife of a machine for cutting a moving cigarette rod into lengths as described in Specification 324, 379, and of the kind comprising a grinding element located adjacent a position in the path of the knife at which the knife has an axial component of movement away from the grinding element the surface of which is so inclined to the plane of the knife that successive points along the eccentric edge touch successive points along the inclined grinding surface as the knife moves, the grinding element is a wheel with a peripheral grinding surface and is pivotally movable solely about a fixed axis to different grinding positions corresponding to different paths followed by the knife when its speed of rotation and extent of axial movement are altered, e.g. for cutting cigarettes of different lengths, and the pivot is so located that the inclination of the grinding surface varies in such manner as to maintain the degree of eccentricity of the knife-edge substantially constant. As shown applied to the cut-off mechanism of the machine described in Specification 324,379, [Class 130], a grinding wheel 1 having a peripheral grinding surface 2 is rotatable by a pulley 10 in one arm 3 of a bell-crank lever pivoted at 4 on the machine, the other arm 5 of the lever being urged by a plunger 7 and spring 6 into engagement with a cam 8 which may be rotated by hand to effect angular adjustment of the lever. The camshaft 14 carries a serrated locking collar 13, see Fig. 1 (not shown), which is urged by a spring 15 into engagement with a similar fixed collar 12. The collar 13 is graduated to facilitate setting of the cam for different adjustments of the cut-off mechanism. The cam may be replaced by a screw.

摘要： An adhesive-applying device for use in an automatic machine having a duct through which adhesive is fed direct to an adhesion surface is so arranged that a portion of the duct accommodates a movable (e.g. slidable) member having a passageway formed therein so as to permit passage of adhesive through the duct when said passageway is in communication with the duct, the arrangement being such that on movement of the member to bring its passageway out of communication with the duct, the passage of adhesive through the duct is cut off. The automatic machine may be fitted with means integral with or coupled to the movable member which when actuated by a part of the machine causes the movable member to open or close the passage or to open and close it alternately. Referring to Fig. 1, a narrow cylindrical duct 4 has an extension 7 at one end forming a discharge nozzle and an extension 8 at the other end for attachment to an adhesive supplying pipe 9. slidable member 11, whose ends project from the apparatus, has an annular groove 12 which can be positioned either in alignment with the duct 4 thus allowing adhesive to flow to nozzle 7, or out of alignment thus preventing such flow. In Figs. 2 to 4, a body 15 having a nozzle 16 and sliding member 17 is fixed to a pin 18 surrounded by torsion spring 22 and pivoted in fixed bearings 19 and 20. Articles 23 are moved by pushers 24 on spindle 25 with conveyer chains 26. Cam 27 engages lever 28 splined to pin 18 so that as pusher 24 leaves adhesive applying station cam 27 engages lever 28 thus rotating pin 18 moving the body 15 away from the pusher path hence causing the fixed cams 29 to move member 17 and so stop the flow of adhesive, after which torsion spring 22 returns body 15 to the adhesive applying station. A detecting device for missing articles is also shown in Figs. 2 and 4. A driven cam 33 is so timed that its depression 42 engages lever 32 whenever an article should arrive at the adhesive applying station. If the article is present, feeler 30 is supported by it and adhesive supplied. If, however, an article is not present, spring 32 lowers feeler 30 rotating rod 31 and causing it to move axially since spiral groove 35 engages screw 36. Thus the groove 37 aligns itself with lever 28 and prevents torsion spring 22 returning body 15 to the operative position. Then cam 33 continues its rotation releasing lever 32 from depression 42 thus rotating rod 31 which again moves axially carrying with it lever 28 thus constricting spring 38. The following cam 27 trips lever 28 out of groove 37 when spring 38 returns lever 28 to its operative position and spring 22 brings body 15 back to the adhesive applying station. Mechanism to cut off the supply of adhesive when the machine stops is also shown in Figs. 2 and 4. When the machine is in operation flywheel 43 rotates freely on the main shaft 39 of the machine with roller 8 in contact with its largest diameter. When the machine stops, the flywheel 43 by reason of its inertia continues to rotate moving along spiral groove 45 engaged with pin 46 (moving to the left in Fig. 4) so causing roller 48 to move under action of spring 49 into the flywheel's smallest diameter, while links 50 and 51 pull body 15 away from the operative position.

摘要： 598,010. Removing dust ; diaphragm pumps. MOLINS, D. W., RUAU, F. F., and MOLINS MACHINE CO., Ltd. Aug. 28, 1945, No. 22110. [Classes 8 (i) and 8 (ii)] [Also in Group VI] In a tobacco feeding apparatus comprising a conveyer element, e.g. a distributing roller 3, and a picker roller 5 having a shroud 12, the roller 5 is hollow and dust is blown off the inner surface of the shroud by jets of air issuing from apertures in the roller 5, and removed by a suction device, e.g. a fan 59 operating through a duct 13. The picker-roller which is adjustably mounted and the air is blown in short blasts through staggered perforations 34, Fig. 3. The air is supplied by a pump comprising a rubber diaphragm 51 bonded to a disc 50 which is reciprocated by an eccentric 41 through a strap 42 and a lever 44. Valves 56, 57 are shown, but they may be omitted, the air then being both drawn in and discharged through the perforations 34. The diaphragm instead of being stationary as shown may rotate with the picker-roller. A further similar pickerroller 4 rotates adjacent the combining roller 1. as described in Specification 384,050, [Group VI]. The shrouds are extended by,walls 6 and 8 to the points where tobacco is thrown off the rollers. The application is also described to the machine described in Specification 441,402, [Group VI], in which the picker-roller withdraws the tobacco from the end of the space between a concave guide and a pin roller, a fixed brush assisting in the removal.

摘要： 578,477. Automatic ordnance. MOLINS, D. W., RUAU, F. F., and MOLINS MACHINE CO., Ltd. April 13, 1942, Nos. 4864,7039,15838 and 16685. [Class 92 (i)] Relates to automatic loading appliances for guns using fixed ammunition in which the breech is automatically closed on the insertion of a round and automatically opened to eject the cartridge case. According to the invention, a spring- pressed rammer moves the base of a round forwards, from a feeding station or magazine situated clear of the breech and behind the chamber face, to the breech-aligned position along a cam-controlled path, the nose of the cartridge being presented to the gun breech prior to or during ramming. The rammer is mounted on a lever pivoted to a recoiling carrier, and control means is provided to swing the lever at the end of recoil so that the rammer is positioned behind a round at the feeding station, a further control means acting to move the rammer towards the gun axis and into alignment with the gun breech during the feeding stroke. To permit of hand loading and clearing jambs, a spring latch device is provided to disconnect the rammer from its driving springs. The breechblock 5, Fig. 1, closed automatically in usual manner on the engagement of the loaded cartridge with the extractors, is opened automatically during run-out of the barrel by a cam 203. Hand gear 204 is provided for opening the breech to load the first round. The gun cradle supports the loading apparatus on members 7, 8, the member 8 serving to guide a recoiling carrier 9 which supports the rammer 12 by links 10, 11 swinging on pins 22, 23. The link 11 has a lever 17 engaging a cam 18, Fig. 2, and cooperates with a cam 19 on the breech. The carrier is urged forwards by springs carried in tubes 13 and a catch 28 on the carrier engages the abutment 30 of the springs by a hook 29, the catch being releasable by a lever to disconnect the springs for manual loading. On firing, a catch lever 35, Fig. 2, on the gun engages during recoil a projection 39 on the carrier 9 until this is engaged by a catch 27, Fig. 1, to hold the rammer springs in cocked position a roller 37 on the lever 35 engaging a cam 41 to disengage the lever from the notch as the recoil proceeds. Towards the end of recoil, the rammer swings upwardly by momentum and by the action of the cam 19 and engages a rubber buffer 49 being retained by a catch 52. The cartridges are fed between bars 102, 103, Fig. 6, by a roller 119 on a spring-pressed lever 21 pivoted at 107 and having a short arm 109 linked to a spring arm 112. The roller is spring mounted for tripping over rounds in the full magazine. A member 136, Fig. 5, acts as an end wall to the magazine and depresses the nose of the round to feeding position then rises one step to hold up the succeeding round. A cross-shaft 68, Fig. 6, carries two levers 125 with rollers 126 engaging cam 127 on plate 128 on top of the breech to rock a crank 67 to and fro during recoil and run-out. This crank acts to move the depresser 136 in two stages and also operates a block 63. This block has a pin to discharge catch 27 to release the rammer near the end of run-out, and a plate 134 to operate a catch 129 on the magazine which separates the rims of two adjacent rounds. The rounds are supported prior to ramming by a pawl 137, Fig. 7, and by a yielding stop 141 struck by the rammer head to release the round on to pins on the head. 'For dealing with projectiles of different lengths, a breech extension piece 151, Fig. 5, is provided, a support 150 on top of the breech receiving the nose of the round on its first fall. On release, the rammer head moves the base of the cartridge downwardly and forwardly up to the chamber face. To load the first cartridge, the breech is opened by handle 204, the coupling 29, 30 is broken and the carrier and rammer drawn back. The round is placed with its nose on extension piece 151 and its base on the rammer head pins. The rammer is pushed forwards to feed the round and the extractors release the breech-block and the coupling 29, 30 re-engages. On firing, the cam 19, carrier 9 and rammer 12 move back until the carrier is held by catch 27. The gun and rammer continue to recoil until the rammer is caught by catch 52 out of the path of the breech. The rammer is held during the major part of the recoil by a stud 42, Fig. 2, running on hinged cam 43 which prevent the links swinging upwardly on pins 22, 23. At the start of recoil, depresser 136 is lifted to allow a round to feed with its nose against a guide 146, Fig. 6. The barrel then runs out, the breech is opened by cam 203, the depresser 136 is moved downward in two stages by cam tracks 226, 227, Fig. 5, and the nose of the round passes on to plate 150 and extension 151 by way of a cushioning lever. The final movement of the depresser releases catch 27 holding the rammer which moves the base of the cartridge forwards and downwards in a path determined by the fixed cam 18, the stud 42 engaging the cam surface 243, Fig. 2. A retainer shoe for the round on the breech-block 5 prevents rebound. During the feed, the round successively occupies the positions marked X, Y, Z in Fig. 2.

摘要： 557,570. Lathes. BEST, C., RUAU, F. F., and MOLINS MACHINE CO., Ltd. June 2, 1942, No. 7477. [Class 83 (iii)] A lathe for turning hollow work pieces such as cartridge cases for small arms ammunition has means for rotating the work-piece by engagement with its bore and for determining the axis of rotation of the work-piece from its exterior surface so that surfaces such as an extractor groove are turned concentric with the exterior surface. In one form a bed plate 1 has a fixed headstock 2 carrying a hollow spindle 3 which encloses a slightly flexible mandrel 5. An extension bracket 6 on the headstock carries ballbearing steady rollers 7, Fig. 3, and a fixed tool 8 of notched disc type which trims the skirt of the case W as shown on the right of Fig. 22. On the right, Fig. 1, of the tool 8 is a form tool 11 which is secured to a slidable rod 12 and which serves to trim off the flange and turn a groove at the left-hand end of the work-piece, Fig. 22. The rod 12 is reciprocated in a guide 13 by a cam 14 on a cam shaft 15 and the upper end of the rod is stiffened by linkage extending from a bracket 25. A rod 29 is reciprocated in a bracket by a cam 36 and carries a rotatable push-rod 33 which can engage and rotate with the end of a work-piece. The work-pieces are supplied from a hopper 46 which may be as described in Specification 545,661 and delivers blanks singly base downwards through tube 47 to a member 48 reciprocable in a slide 49. A transfer device 45 including a blank receptacle 51 is swung through 90 degrees by a cam 38 on the cross shaft acting through lever 40 and link 43. In the receiving position the transfer device pushes back the member 48 so that a blank falls into the receptacle and is then transferred to a horizontal postion, Fig. 1. At the beginning of the operation a stop collar 52 on the mandrel engages the end of a cap 53 under pressure of a spring 54. In this position the push rod 33 is moved to the left and pushes the blank on to the mandrel, the transfer device then being moved away. Further movement of the push rod moves the mandrel and blank to the left to the Fig. 1 position. As the blank moves past the tool 11 the flange is turned off by this tool which is then moved inwards by the cam 14 to form the groove, The skirt of the blank is also trimmed by the tool 8 as the push-rod reaches the end of its stroke. The push-rod is withdrawn and the blank is then ejected by the end of a rod 56 passing through the mandrel and operated by a cam 62 and lever 58. The machine is driven from a transverse shaft 63 connected to the cam shaft by worm gearing 65 and to the mandrel by bevel gearing 67 and belt 71. Alternatively the cam shaft and spindle may be respectively driven independently by low and high speed motors. The cross shaft 34 is driven from the cam shaft through bevel gearing 73 and chain gearing 77 while a further chain drive 79 from the cross shaft operates the hopper. In a modification, Fig. 6, a mandrel 81 is secured to the spindle by a collar 83 and instead of using an axially movable mandrel the headstock itself is slidable in guides 86, up to a stop screw 93. Another headstock supports a rod carrying a. rotatable pusher 96 normally urged rearwardly by a spring 97 but moved to push a blank on to the mandrel by a cam 99 and lever 102. A bracket 92 supports steady rollers 109 and carries a shaft 112 supporting a lever 114, Fig. 8, operated by a cam 116 and carrying a tool 118 which trims off the flange during axial movement of the blank and is then moved inwards for the forming operation. A fixed tool secured to the bracket machines the skirt of the blank. An ejector mechanism similar to that described above ejects the finished blank. In both modifications the rollers are adjusted slightly nearer to the blank axis than would normally engage them with the blank so that the mandrel is slightly displaced and the blank firmly pressed against the rollers during machining. The rollers may be slightly convex at the ends nearer to the push rod. The mandrel may be barrel-shaped or shaped to fit the exterior of the blank and is preferably knurled. The mandrel end may be split, Fig. 12, and the ejector rod 135 tapered so that movement to the left expands the mandrel. In a further modification a chuck 140 has three jaws 143 separated by springs and having a groove 145 fitted with a friction ring 146, Fig. 17, in which the work advanced by the pusher is gripped after which further movement closes the chuck to grip the work. Modified forms of friction ring 146 are described. The work is supported in its interior by a flexible mandrel as in the previously described modifications. The chuck rotates freely in ball bearings 149 or it may be driven by a separate pulley 150 to relieve the load on the mandrel. The skirt is trimmed by a tool mounted in a holder 151 which may either be reciprocated or fixed so that the operation is performed as the work is pushed into the chuck.
