Abstract: 6618. J÷nk÷pings och Vulcans Tõndsticksfabriks-Aktiebolag. Dec. 11, 1909, [Convention date]. Machines for making boxes. In a machine for making the parts of match - boxes, the part of the blank that forms the sides of the box, after being placed on the mandrel, acts as a support for a swing- able arm mechanically connected to a disconnecting- device, so that the whole machine is stopped if no box side is moved on to the mandrel, or if an imperfect one is supplied. The machine described is one for making the drawers of match-boxes. The mandrel 1, Figs. 1 and 2, on which the sides are formed, rotates continuously or intermittently, while the mandrel 2 supporting the bottoms is capable of being moved towards or away from the mandrel 1 by a cam 6 acting on a roller 7 attached to the axle of the mandrel 2. The sliding of the parts from the first mandrel to the second one is effected by springs 3 moved by a roller 5 engaging the cam-groove 4. A spring pin 9 in the side of the first mandrel serves to hold the bottoms supplied from the magazine 10 by the slide 11, against the mandrel 2. Supported in the frame above the second mandrel is an anglelever 12 carrying a roller 14 running on the cam 6, and also carrying one end of a lever 15 connected to a lever 17 pivoted about the pin 16 and terminating in a link 19 adapted to actuate a link 23 on the shaft 21, which is carried in bearings beneath the base-plate 20. If a box blank is in proper position on the mandrel 2, the arm 12 rests against it, and, in consequence, the roller 14 does not fall into the groove in the cam 6 and the lever 17 is not actuated, but should no blank be in position on the mandrel, the arm falls into a groove on the former, and as a result, the link 19 is caused to actuate the part 23, causing the turning against the supporting-springs of the shaft 21, and bringing into action the disconnecting-device of the machine. The disconnecting-device comprises an arm 27 journaled in the bracket 26 and adapted to swing in a vertical plane, the arm carrying at its free end a roller 28. This arm is normally raised by a double-armed lever 30, the lower end of which is kept in engagement with the arm 25 by a spring. The machine has a friction clutch 33, one member 34 of which is movable along the main shaft 35, and is caused to engage the other member by a spring 36. The flange 37 has a notch 38 in which, when the arm 30 is depressed by the turning of the shaft 21 and the arm 25, the roller 28 engages to disconnect the clutch and stop the machine. The stopping is also effected if no bottom or an imperfect one is supplied from the magazine 10. The operating-slide 11 is reciprocated by the rod 46 and the arm 48 from the shaft 47; the arm carries a rod 49 sliding in bearings 50, and the side of the magazine carries four guides in which the slide 56, Fig. 8, is movable. Journaled in the upper part of the slide is a rod 57 normally held in position by a stop ring 58 and spring, and the lower part carries a pin 65, Fig. 10, co-operating with a shoulder 62 on a spring-pressed arm 63 pivoted to the rod 49. The rear end of the rod 57 is engaged by one part of a three-part pivoted arm 67, the second part carrying a roller 68 bearing on the edge of the cam, and the third arm is connected to the rod 70, the lower end of which bears on the arm 24 attached to the shaft 21. When the slide 11 advances to deliver a bottom, the rod 49 moves with it, and the shoulder 62 engages the pin 61 and causes also the slide 56 to advance. If the bottom advanced is perfect, the rod 57 bears against it and prevents the roller 68 from engaging the notch in the cam-. If the bottom is imperfect, the rod is not supported by it, but enters a slot in the slide 11, the roller 68 entering the notch in the cam, and the rod 70 being moved downwards to turn the shaft and cause the disconnecting of the clutch.
