Abstract: 17,659. Mackenzie, J. W., [Continental Match Co.]. Aug. 14. Matches.-Match-splints are cut from a series of parallel veneer strips by a transverse knife and forced into carriers for removal. In a frame consisting of side pieces 10, Fig. 1, with projections 11 and upper pieces 12, is mounted the driving-shaft 13, gearing with the shaft 14 from which bevel gearing drives the disc crank 18, Fig. 2, on the shaft 17, supported by the bracket 17<a> which joins the side frames. By means of a link 19 and arm 20 of adjustable throw on the shaft 22, the oscillation is effected of the arm 27, link 28, and knife 29, moving transversely across the machine through an aperture in one of the side frames. The veneer strips are supported on edge lengthwise on the table 32, Fig. 4, between guide-plates 32<a>, and they are fed forward between fixed vertical fingers 33, the knife then passing between the fingers and the guide-plates, while the faceplate 30, attached to, and parallel to, the knife, passes between the fingers and guide-bars 35, supported by arms 37. The lower bar has a keyway for a feather 31 on the face-plate. The ends of the strips are thus severed and held in position until the cam 44 brings down the rod 42 and depresses the plungers 38 attached to the bar 39, so as to press the splints between the serrated cross-rods 68 of the frame 67, supported on tracks 70 and brackets 71 extending across the machine. The bar 46 is caused to reciprocate between guidepieces 45 by a pin 47 engaging with a slot 18<a> on the disc 18. By the linkwork 48, 49, 51 the bar causes intermittent motion of the ratchet-wheel 53 on the shaft 50, and thereby of the mitre-wheels 55, 56 and shafts 57 which gear, by means of spur-wheels 59, 61, Fig. 4, with other lower parallel shafts 72. These shafts carry feed-wheels 60, 62 which engage with the rods of the splint-carrying frame 67, and move it forwards. The bearing for the lower shaft is in a block 63 which can be made to slide in the block 58 carrying the upper shaft by means of the screw 66, and is locked by the screw 65. The forward motion of the carrying- frame follows the withdrawal of the knife and face-plate 30. and, to allow the splints to pass, the shaft 57 in front of the knife is not carried across the machine. The shaft 50 also drives, by means of gearing 74, 75, 76, 77, Fig. 1, the transverse shafts 78, 79 on which are mounted feed-rolls 80, 81 of soft rubber, which grips the edges of the veneer strips and feed them forward, the bearing of the upper shaft being adjustable in the guides 83 by means of a screw 84. Fig. 10 shows an alternative feed gear consisting of rotating thin metal discs 87, one on each side of a veneer strip, spaced on the shaft 79 by collars 88. By means of capstan-headed screws 93 and threaded wedges 92 the plates 91 can be forced tightly against the discs, which latter are slotted into segments, so that when each segment has passed the projecting ball 95, its pressure on the veneer strip ceases. The discs may have roughened surfaces. A machine is also described which has two knives operating simultaneously from opposite sides and meeting in the centre.
