Specliration forming part of Letters Patent o. 5,496, dated March 23, 1848; Reissue No. 359. dated Y March 11,1856, A

To all whom, may concern:

lBe it'knownthatLEwisSMrTn, of the city, county, and State of New York, late of Brandon, Rutland county, Stateof Vermont, did

invent certain new and useful Improvements in Machinery for Splitting lor Cutting Blocks of lVood for Match-splints and other Purlposes; and the following is hereby declared to on the main driving-shaft, upon which Iare, secured two levers to work the cutters. These levers are made witha joint in them, (though may be used without any jointin them,) and have stiffcucrs or springs. at l the back of the joints tothrow them `out ofj oint when the cutters have ceased to find any resistance in',

splitting the block. To the top of thecappiece connecting the jointed levers to the cranks -two arms are jointed, the opposite.

'ends of which are similarly connected toa cross-bar, through the middle of which yis a socket. into which fits a pin on the .cross-head,

of the crimping or compressing. levers` forf the purposcof working them by means of the cranks on the main shalt. The fulcrums of these levers work in boxes or' caps attached to the' upright side pieces of the frame. On the lower end of cach lever is acrimper faced A girt of iron is bolted to the upper side of the b lockiwhile being matted on its lower sideby the action ot' the crimp ing or compressing levers. NVhen the lower surface of the block has been crimped or matted, theadjustable cap or clearer plate and fecdwheels are pushedgforward, so yas toadfinit ofthe cutters making a new cut on 'entering thcblock again, the block being carried or fed forward between the intervals of crimpving by means of suitable feed-gearing for that purpose but to describe the invention more particularly reference will be had to the accompanying drawings.

'the crimping or compressing lever; `a detached View of themain shaft. ,Fig. 5 is 'l Figure lis a back view of the machine. Fig. 2 is' a side view,having'one of the upright side pieces removed. Figs. 3 and 9 are'views of Fig. 4 is a reversed View of the setting ot' the cutters. Figs. 6, 7, and 8 are representations of the lower and top feed-boards and cutting-box.

The letters of reference 'in the several 'drawings refer to like parts wherever ,they occur.

Letter A represents-frame of the machine.

ter-holder frame or vboats;I by' a pin or screw.

Letter F represents two springs securedto back of the jointed levers E, for the purpose of throwing them'out of kj oint when the cutters have passed through the block farenough to split it withoutcutting through the matted f lower surface and uponthe bed-plate.

It will be'obvious that levers without joints in them can be used by shortening the length of the stroke of the cranks upon which they .work'to accomplish the same result; but as i soft -wood 'may be used generally anddoes not split freely at all times, it is desirable to have -the knives to cut as near through,fand yet not cut the bed-plate, as possible, and therefore I have preferred to use jointed levers, though others will answer.

Letter G is the cutting box or 'fra-me to which the four cutters lor knives are attached lThese knives are setor arranged in' such a position as to intersect leach other at their cen-- ters, so as to make a cross of the square and splitting the blocks with an inverted-V-shaped cut, so thatat each feed of the machine the front knives cross the' split made bythe back 4knives at l the angle ofthe-split, which would rbe represented thus: p ,that is,` 1 1, 1234 1234- first cutA of th'e knives; 2 2, second cut; 3 3,

Letter J are tw'o arms connected bya'cross-- bar at one end, and' attached by means of joints to the heads of the levers E, so that when the with the face ofthe bed M of the machine.

4 Letter L represents the faceof the crimper,

, which is at right angles to the long arms of4 the lcrimping-levers K, and is adjusted upon its.

axis so as to work up between the open sides of a slot in thebed-board Moi' the machine, so

"as to compress or mat the surface of the block before being split and asit passes through the machine. .The object of this matting process is to cause the blocks, WhenspIit for matches, 4to adherejtogether on their lower surfaces, and thereby avoid rehandling the splints in thel process of dipping, packing, Src.

Letter M visthe feed or bed board of the machine, having a'slot transversely of it, so as to allow the crimper L to. pass up through it to act upon the block ofwood.

Letterl N is a guide-strip upon the front end of the bed-board. l Upon each side of this, l

from the front of the machine, the block or blocks of wood areV placed and worked forward by hand till the feed-gear R R (or other equivalent feed-motion)takes hold of them and carries them forward to be acted upon by the cutters. z

, Letter `0 represents an `adjustable cap or `clearer plate having slots -in it to allow the cutters to pass through, to act upon the wood and hold it from lifting or risingup to follo'wthe knives when. drawn back after making-the cut; also, through the. front edge of this adjustable cap or clearer plate isV an angular opening,`throughl which aportion of the girt-pece P extends about` the thirty-second of an inch below the lower-face of thecapplate, and against which the upper surface vof the block of wood presses during the operation vof crimping or matting its lower surface. While the machine is in motion, cutting t-he blocksof wood, the adjustable cap or clearer plate is acting upon or holdingthe blocks down till the cut is made, after which it is drawn back to allow of the feed. When the adjustable cap or'clearer plate has .been drawn back, after the knives have done their work, the block or blocks are then fed up a` 'sufficient distance -forthe knives toymake a new cut. j Letters R represent several vertical shafts standing or resting upon steps `ou the lower l The upper ends of these shafts extend up through'openings in 'the bed-board M and into oblong slots in the cap-plate O. The object??-` this is. to adjust them to the varying widt s of blocks to be cut, and of holding them firmly under the action of the cutters by means of spiral springs or y other equivalent device pressing against them `and the side piecesk of the frame. Ou the lower ends of four of the vertical shaftsl are small pinion-wheels which gearl into screw# threads cut upon the surface of two hQrizonf tal shafts, and on their upper ends are four ratchet feed-wheels, for the purpose of feeding the blocks into the machine. It will be 'obvious that this precise-arrangement for feeding the blocks may be varied'by the use of endless bands and other common and'well known devices, and therefore claim the privilege of using any equivalent feeding apparatus for the purposes set forth. The two back l.

vertical shafts are notconnected with the feeding-gear, and have onlyk carrying rollers or buttons on their upper ends, and by means of a spiral spring connecting them together cause the carrying rollers or buttonstok press at opposite sides'against the splints as they come from under the knives, to prevent them from falling. A

Letters S are. four short arms adj usted and arranged between the uprights of the frame and the upper ends of the vertical feed-shafts, and by means of spiral springs on them act as self-regulating adj usters of the feed ratchetwheels against the sides .of the blocks, so Aas to accommodate their varying widths.

Letters '1 are two horizontal shafts having screw`threads cut upon them, and gearing intov pinion-wheels on the lower ends ot the vertical feed-shafts, and. driven by means of a pulley on the end .ofeach of the shafts and bands from the pulleys on the main shaft C.

Letters U are pulleys `on the ends of the horizontal shafts, and V- V pulleys -on the main shaft C, for communicating motion to thefeedgear. v

Letters W arebands connecting the mainshaft pulleys to the feed-gear pulleys, and X two posts to support the bed-board of the machine.-

' Having now described the invention-and its operation, 1 will proceed to state what I claim and `desire to-secure by Letters Patent of the cutters, arranged and operating substantially' as hereinbefore set forth, in combination with the cutter frame or box, for the purposes hereinbefore described, and also the use ofthe cutters and cutter-frame, arranged and operating as hereinbefore described, in combination with an adj ustable' c ap or clearer plate, for the purpose of holding the.Y blocks of wood while under the action of the cutters, substantiallyv as hereinbefore described.

2. The jointed levers or their equivalents, with or without springs at their backs, for the purposes hereinbefore set forth, and their coinbination with the cutters, and, crank-motion with the bed-board M, for crimping or matl ting the lower surface of the blocks, substantially as herenbefore described.

4. The use ofthe shafts Rand ratchet feedwheels or equivalents, for the purpose of feeding the blocks through the machine, in combination with the adjustable cap or clearer plate and bed-board, when used for the purpose lof splitting blocks of wood.
