Like letters o f referenceindicateI in each.
My inventionrelates tov machinefo'r 'ed-gv;
ing and slitting boards. .'f'lljorf-nearly all machines of this class have a feed-table', 'a Y side rail for a gage, one or more 'movable orf' pairs of pressure-rollers. My presentinven-'l tion consists of improvements 'in-the-l'feedy de;`
vices, both those in front and' those:inf'tl'ef4 rear of the saws, and in the guide/'or'*gagei substantially' as devices employed in feedin` hereinafter described. v
To enable others "skilled in the and use my improvement, I will proceed' to describe -its construction andmode` of'foperation. Y
The frame A ofthe machine is of the usua-l" con struction. The side'lor. gage l'rail- 'Bg the rest-rollers B1, the sawmandrelfD,fand the' motion, so as to provide for the passin g through of boards of different thicknesses. It consists of an outer or roll part a, Fig. 3, which is provided with a band wheel or pulley, al, and both are slipped like a sleeve onto the shaft 2"solas to have a4 rotary motion on; and' indes? so'as'to catchfupo'n the end of a thick plank" and;V rise onto it* without any 'aid'r from the@ operator; but when l"addition-al aid isf-req uired','` theope'rat'or," bywo'rkiugj theflever jl, cari raise or. lower" the rollerH' at pleasure. This".` motion` is communicated directly to the shafts-j ia? l'and the "pinions r; '.Dhese pinions'' nneslfi-`v into the "curved racks c1, and moveup" and@ down"V with l a 'uniform-*motion Henceyboth endsuof -the -'roller H will L alwaysloe'at thei same di'stance from fthe lower 'rolly'and -wil1`V consequently beart evenly along' vvthe jentiie Y widthofj. the boardg'and thereby secure v'uni-"ff formit-y-'f feed. `The 'roller` hence performs-f =its` function'of a 'feedlroller,'e'ven whenjchan ingitsposition vina vertical direction? l v -lheanaxt part *ofA my inventionrelatestjo la lo guide -th'e lumber Yin a direct'line lforward so that the saw shall follow the grain ofthe wood. To prevent this, and insure a feed tried, but with poor success, as the teeth entered the face of the board to such depth as to injure the face of the dressed board. As a substitute for such toothed rollers, I have sharp spurs,s s, at various 4points along its length. These spurs are sharp enough to catch the strips into which the board is cut, and prevent their swervingl from a direct line forward, but are so short that they will not 'sectionaly rest-roll, 1?,whichisl used,'prefera-1` ly,witho.utan'y pressure-roll; and is designed "t asl it passes' frornf the saw. The 'tendency' 'of'ig the ;boardso1netimes` is= "to :swerve laterally',y
directly forward, toothed rollers have been l devised a roller, P, with a series of short,
enter the l.board to such depth .as to.cause injury. They may be made on theface of a solid roll, or' the roll may consist of a series of rings, p, provided with spurs s, such rings being slipped onto a common shaft, 'so as to be capable each of an independent motion. This latter is the preferable construction. Then, if two operators are at work on different sides of the machine, the `sections p at the opposite ends of the roller P may work independently of each other. While the rear end of one board is resting on a part of the sections p, soI as to prevent'theni from reirolv ing, another board may be passing along over the other sections, which will rotate freely.
I have also devised an adjustable side or gage rail, shown at R,=to.be used as a guidein feeding. `Such guides havev been madev adjustableby means of pins therefrom extending' down through slots,and they were held inv place at the desired point of adjustmenty by nuts or set-screws. But, for every diiferent width `to, be sawed offA the edge,.they operation of sawin-g mus-t be stopped till the adjustment is changed. To overcome this difficulty I attach to thefeed--tab'le the plates d,each y having a series of inclined slots,e e, connected together by a series ofslots-,e e', which run in the direction of the feed motion.- The 'gagf rail R- is moi/"ableV It has pins, as, indicated `by dotted lines at 1^" 1",Which play inl theslotse. e. The operator, knowing vthe breadth of edge he wishes to cut from the board, sets the gu-idetrail R,with its pins, r', in thek proper l slot c. To set it for cutting oif another breadth of edge,he slips the rail, with its pins passing along the inclined slots e,in' or out,\
as he may desire, till the pins r i" come in the proper slot e', and then the work proceeds.- The pins, when in anyof the slots fi/,will keep their place till shifted by the operator toV another slot. In connection with the guideerails it is desirable to use some device which,after the forward end of the board has passed between the feed-rollers', and While it is being fed forward thereby, Will hold its edge fair and true against such guide-rail, and thereby relieve the operator to that extent. For this purpose I employ the Wheels or rollers n, which are made with' short, sharp spurs s', similar to those, s, already described.- These wheels or rollers n I mount on horizontal shafts or stems n', whose axes incline alittle forward, sothat, as the board advances, the
'automatically hold it in place.
spurs .8", engagingits under surface, will, by the direction of their movement, while thus engaging the surface, tend' to press the board over against the guide-rail, and thus rBhe operator then, after entering one board, is free to get another ready while the-former one is passing through the machine. The spurs s s may be made either on the face of cylindrical rings, or they may be cut out like small saw- A teeth on the edge of a circular sheet-metal plate, of the proper diameter, and such plate be slippedfontc'thestem orshaft, and held in place by nuts and washers, in the usual way. The latter mode of making them, on account of its cheapness, and the facility with which v the spurs can be renewed,- is probably prefer able.
What I'claiin as my invention, and desire toy secure by Letters Patent, is
1.- As'- a means for securing a parallel motionin the movable roll of a pair of feed-rolls, a pinion on each end of such `roll,meshing each into al curved-toothed rack, substantially as set forth.
2. 'rile momia-1ev feed-mii H,- @onsisting of a,
shaft by means of 'which the roll is moved verticallyyand a roller part, a, with its pinionY 0r band wheel, a', slipped onto the* shaft, so as to have a fixed positive rotary motion, in-
dependent of the shaft, and at all points of the vertical travel of the shaft, substantially :as set forth. y
3. The sectional rollP, in combination with pressure-rolls H H', substantially as and for the purposes set forth.
4. In a machine for edging or slitting boards,
the combination of a side guide or rail, fixed' or adjustable, and a spurred guiding-roller, n, arranged with its axis at an acute angle to the direction of the feed, substantially as and .for the purposes described.
5. As a device by which to set an adjustable guide-rail, a series of slots, e', running in the direction of the feed, two or more in nurnf ben-when connected with each other by an yinclined slot or slots, substantially as 4set forth.
g In testimony whereof I, the said EDWARD H. SrEAaNs, have hereunto set my hand. EDWARD H. STEARNS.
