Abstract: 26,247. Criswell, J. A. E. Dec. 23. Cutting-up.-Relates to match-making machinery, more particularly to machines in which the splints are cut from veneer, such as that shown in vertical section in Fig. 1. The veneer blocks are placed in a hopper 11, and are forced inwards by a follower 13, and rest against an abutment plate 14 and under a plunger 15, which is reciprocated by means of levers 18, arms 20, 21, a strap 22, and an eccentric on a shaft 23. The blanks are forced by the plunger to a cutting-device 24, shown comprising a series of circular cutters 25 spaced along a shaft 26, and a preferably metal roll 27 against which the blanks are cut. The cut splints are forced between guides 28, 29 to a separator 30, Figs. 1 and 3, shown consisting of two reciprocating members 31, 32 provided with fixed fingers 37 and sliding plates 38, 39, and with backing-plates 44, 45 movable in slots of the opposite member. Rock levers 53 are connected by links 52 to the member 31, and by rods 54 to the member 32, and are operated by means of cam heads 56 and cams 59 on the shaft 23. Rods 48 pass through slots 49 of the two members, and through cam slots 50 in the plates 38, 39, and ride at the ends in cam-grooves in the framing 10. Plungers 60, arranged in rows corresponding to those of the separated splints, are secured to a plunger head 61, which is provided with projecting guide-rods 63, and normally forced upwards by springs 64, and operated by means of levers 65 and cams 67 on the shaft 23. The plungers 60 force the separated splints into a carrier 68, shown consisting of sections or frames 70 removably supported on an endless linked carrier and provided with rows of splint - holding devices, which comprise opposed plates bent at intervals to provide splint sockets and out on the bent portions to form spring fingers. The carrier is supported by a bracket 77 and a bar 78, which also forms an abutment for the splints when forced into the carrier. The sections are provided with teeth 79 engaging driving- wheels 80 driven from the shaft 23. The carrierratchet mechanism shown in Fig. 32 is intended for use where twice the usual throw is desired at stated intervals, some teeth 105 of the ratchetwheel 106 having an overhang, while others 107 have not. The separator 30, Figs. 1 and 3, is arranged for dividing the splints into four rows, and each set is positively held. In a modification for producing three rows, the plates 38, 39 are dispensed with, and the fingers are all fixed, and one set of splints is free to move toward the abutment after the other two sets, positively held, are separated. In another form of separator, shown in Fig. 25, one member 83 is stationary, and the other member 84 movable, and each member is provided with fingers. A bar 86 is fixed to the member 84 and forms a backing for the splints, and an opposed bar 87 forms a facing for the splints, and is held on the member 84, and adapted to move into openings in that member, and forced towards the bar 86 by springs 88. A series of springs are provided instead of sliding plates. Openings for the passage of the bar 86 are provided in the stationary member Splint-engaging devices, for use in connection with the separator just described, or in place of the springs or bar 87, consist of slides or fingers 98, Fig. 31, provided with springs 99 on opposite sides, and slidingly held in the movable member 84 and connected by a crossbar 100 linked to arms 102,which are pivoted to brackets 103 and adapted to be engaged by a crossbar 104 on the rods 92 operating the member 84. The separator shown in Fig. 33 consists of two movable members 116,117 comprising sliding plates &c., 118 formed together in four sets by bars 119 connected in pairs by the rods 120, which are connected by links 122 to levers 123 operated by cam heads or slides 126 spanning the driving-shaft 23 and operated in turn by cams 128. In the separating- device shown in Fig. 38, the splints are first divided into two parallel rows by a fixed separator 130, comprising a single way 133 below the cutters and channels diverging at right-angles to the single way, or forming a continuation thereof, and are further divided by means of a carrier and reciprocatory separator 135, working at right-angles and beneath the channels, and comprising members 138, 139 forming rows of' splint-holding devices 140. A cutting-device, in which there are two cutter spindles, with the cutters bevelled on one side only and overlapping, may be used for initially separating the splints into two rows, instead of the meaus 130, Fig. 38.
