SPECIFICATION forming part of Letters Patent No. 290,560, dated December 18, 1883.

Application filed September 24, 1883. (No model.)

To col; whom, it may concern.-

Be it known that we, GILFORD FLEWWEL- LING and GILBERT J. Hnnnrs, of Hampton, Kings county, New Brunswick, Dominion of Canada, have invented a new and Improved Match-Sawing Machine, of which the following is a full, clear, and exact description.

Our invention consists of improvements in the arrangement of apparatus for holding and shifting the blocks to be sawed, and also for presenting them to the saws, in a machine in which the blocks are carried on slowly-revolving horizontal tables or disks to the grooving or pointing saws, also to the slitting-saws, and also to the cutting-off saws, whereby it is designed to improve the efficiencyof such machines, all as hereinafter fully described.

Reference is to behad to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of our improved machine, with a part in horizontal section, and with one of the slitting-saws removed from the disk which carries said saws. Fig. 2 is a detail of one of the block-carrying disks and one of the carriages for the blocks to be sawed, in section. Fig. 8 is a plan of Fig. 2. Fig. at is a plan view of a gage and holder that is em ployed to regulate the setting of the blocks to the saws. Fig. 5 is a longitudinal sectional elevation of the gage and holder represented in Fig. 4, and Fig. 6 is alongitudinal sectional elevation of the machine on the line as x of- Fig. 1.

The machine consists, essentially, of the two block-carrying disks a, with a disk, b, between them, carrying a series of slitting-saws, c, together with grooving and pointing saws d, and cutting-cit saws 6, arranged as shown in Figs. 1 and 2 of the drawings, and provided with suitable driving-gear, as hereinafter described,

whereby the blocks, f, tobe sawed into matchcards may be placed on carriages g, and secured in radial grooves h, to be presented to the saws, first to be trimmed, next to be pointed, then slitted, and finally cut off, the blocks being shifted forward each time the cards are cut off until the blocks are finished. \Ve now propose for a better means of holding the blocks, and also to enable larger blocks of the carriage, and the sliding wedge j being placed alongside of the clamp and geared by a cog-rack, m, on its upper edge with a leverpinion, a, pivoted to the clamp at 0, so that the operator may readily shift the lever-in one direction by one hand to release the block, shift the blocks to reset them by the other hand, and reversethe lever to secure the blocks again. hen the blocks f are put in the carriages, they are at first to be set so as only to project sufficiently to be trimmed off at the ends by the saws e, and for gaging them for being so trimmed, and also for being afterward set forward the length of the slitted cards to be cut ofi, we have provided a gage, consisting of the arm 12, swinging around the vertical pivot qof the disk a, and having a vertical gage-stop, 3, against which the blocks are to be set for sawing off the cards, and there is ahorizontally-projecting stop, 15, attached to stop 8, against which the ends of the blocks are to be set for trimming them to begin with. This latter stop if is in practice to be pivoted to the vertical stop 8 at a, and a light spring will be employed to lift it up in the range of the blocks when the said stop is to be used, which spring will allow of the said stop i being pressed down out of the way when it is not to be used. This gage is to be located where the operator stands in advance of the saws c, as represented at the right hand of Fig. 1, and it has a handle, '0, by which to swing it to and from the position of the carriages or blocks. Said gage also has anotched holding-latch, w, pivoted to it in a suitable position under the table for engaging a pin, is, projecting down through a slot, '1, in the table from the carriage g, to hold the table against v sliding forward and backward in the ways 71 when the clamp i is released and the blocks are being shifted. When the blocks f pass the saws e to be trimmed or cut off, the pins an of the carriages run along a cam-groove, z, in any stationary plate below the table, which groove is suitably inclined in the first part, a, traversed by the pin to draw the carriage in- ICO ward, and theseeond part, b, is inclined to shift the carriage outward with relationto the table, so that the blocks pass the saw in a straight line, to be cut straight across, rather than in a curved line, as they would be out if they followed the curve of the tables motion.

The tables a are mounted by their pivots or spindles q in sockets 0, supported on the frametimbers d, and we now propose to gear them with the shaft 6, which carries the saw-disk b, by belts f from a pulley, g, on said shaft, vertieal shafts h, and the worm-shafts 1;, said worm-shafts gearing with the shafts h by suitable bevel-wheels, and also gearing with the disks a by the toothed rims j, said worm-gears being now employed in preference to the frietion-gears heretofore employed for driving these tables. The cutting-off saws e are to be driven by belts from any suitable driving-pulleys, and running on the small pulleys k on their arbors, which are mounted in suitable bearings, m, on an extension, at, of the frame, andwe propose to apply other and smaller out ting-off saws, Z, to the outer ends of these arbors for trimming or cutting in two the last double bunches of cards which are taken from the carriages by the attendant and trimmed) by these saws.

The grooving-saws d are mounted on vertical arbors p, and are driven from the large drum g on shaft 0 by belts 8. Power is applied to shaft 0 by the main driving-belt t and pulley a; The worm-shafts t" are to be shifted out of gear with the toothed rims j, when required, by sliding boxes 1) and rods 10. Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a match-sawing machine, the combination,with the carriage 9, having the flanges k, of the sliding wedge j, e1amping-p1ate i, and the lever-pinion a, said lever-pinion being pivoted to the clamping-plate and gearing with 2. In a matchsawing machine, carriages having clamps to hold the blocks, and arranged to slide in the ways h of the tables a, and also having a stud-pin, w, projecting through the tables a, in combination with a grooved cam or guide, .2, whereby the blocks are made to move in a straight line along the saws 6 while being carried on the revolving tables, substantially as described.

3. In a match-sawing machine, the combination, with the table a and the sliding carriages 7, having clamps for holding the blocks of wood, of the swinging arm 10, provided with the stop-gages s t on its free end, substantially as herein shown and described.

4. In a match-sawing machine, stop-gages s and t, in combination with the carriages 9, having clamps to hold the wood blocks, and being arranged in radial grooves h in the tables a, said stop-gages being arranged on the arm 1), fitted to swing around the pivots q of the tables, substantially as described.

5. In a match-sawing machine,vertical stop gage s and horizontal stop-gage t, in combination with, thecarriages g, having clamps to holffihe wood blocks, and being arranged to shift along the radial grooves 71. of the tables a, said gages being mounted on the swinging arm 2, and the gage 2%, attached to gage s, and being pivoted thereto to be set in or out of range of the blocks, substantially as described.

6. In a match-sawing machine; the combination, with the slotted table a and the sliding carriage 9, provided with pin y, of the swinging arm 1), having a stop-latch, 10, engaging the pin of the carriage, substantially as herein shown and described.
