MACHINE F0231 CUTTING MATCH-SPLINTS.

To allwhom, t may comerm- Be ift known that I, Farsi-1a FrrzennALD, of the: city, county, and Stat-e of New York, acitizen of theA United: States, have invent-- ed', made, and applied to use a new and useful Machine for Cutting Match-Splints.

rlhe following specificationwith thel drawings thereiny ref-erred to, contains a full, clear and' exa-ct description of the machine.

Figure l on the drawings is aplan of the machine asmade and usecl by me. Fig. 2 is a side elevation of the-saine. Fig.4 3 is a representation of the holdingl frame and parts seenF fromv the working end of the m achine.

The other figures are separately referred to and the same letters as marks of reference apply to; the same parts in all the figures.

A is the main frame-carrying; the working parts; B, a side frame to. sustain the outer end of. the shaft a, on which is a drum C from' which a belt communicateswith any first or moving power.

Gn the inner end of the shaft-a, is a fly wheel, b,one arm of which serves as a crank and has a pin c, taking' one" end of a connecting rod, (Z, the other end of which is connected with the slide frame, e, working between the two slides, f, f, secured: to the main frame. On the slide frame, e, the knife, g, is set, the edge of which is placed diagonal to and lengthwise with the frame, with the edge inward. On the end of the slide frame containing the knife and at the place indicated in the drawings by the dotted points, the plate, L, is placed across the frame, having inserted in it a number of points sharp like the points of a lancet standing vertically, each point is set parallel to the center line of the machine and one is placed diagonally to the other in succession as shown by the black lines between the dotted lines on the detached figure, 4. These points or as they may be called gage teeth are intended to divide the piece to be taken off by the knife into splints of the required size and must be placed far enough apart to divide the piece to be cut off into splints of the size required. The working positions of all these parts are shown in Fig. l.

The upright frame, z, z', is placed upon and across the frame of the machine as shown by Figs. l, and 3. Within this frame Fig. 3, are two vertical slide ways, 7c, lo,

' Ato receive the slides, Z', Z, to which the box, m,

is attached as seeny in Fig.k 3. The block of wood to be cut into splints is first putinto the box, m, in Fig.. 3, and there secured at any given place by the screw, n, seenv in said Fig'.y 3. The said box is secured in any particular position by a piece of metal bent aro-und the frame shown in. Fig. 3, and the ends `secured to'said box. rilhis last piece of metal bent around as above, I call a double elbow. The letter, 0,A indicates the double elbow as shown on frame on Fig. 2, Aand the letter, p, indicates the screw inserted linit and which is secured against said frame, z', and thereby the box containing the block of wood is secured atany given point,

of elevation. 0n one of the slides, l, is placed the vertical ratchet bar, w, and through the corresponding piece of the frame, z', is placed the small cross lever, u, connected with the pawl'7 fw, which. works into the teeth in the ratchet, at. rlhe outer end of the lever, u, is connected with and fastened to a horizontal side lever, t. The rear end of this horizontal side lever, t, is secured by a bolt to the rear brace of the upright frame, z', on which bolt the Said lever works as required. The end toward the fly wheel' is turned horizontally, at a right angle forming an elbow or arm across theA slide way on which it rests and indicated by letter, s. On the side o-f the sliding frame on which the knife is fixed and at the spot to which the end of the horizontal side lever extends, when the slide frame is advanced nearest to the ily wheel is placed the cam, g, with its slope toward Vthe fly wheel. These parts are shown on the drawings on a larger scale by Figs. t and 5. The cam, g, passes under the point of the arm, s, as the slide advances toward the fly wheel, and lifts the lever attached to it and depresses the pawl po-int, fw, and brings down the frame and block of wood on it ready for the teeth to mark and the knife to cut off nally and moves on through it with the.

grain, but the edge not at right angles with it but diagonally with it. The knife is 'not forced into the wood byl a. chopping Vstroke but by a drawing stroke, that is whilethe knife is pressed upon and made to penetrate the wood, it is drawn from the point "to the "heel tillit passes across the lower end of the" block of wood diagonally andthus cuts off' the splints. VBy this operation the splints come off" unbroken inseparate solid pieces fit for use.A f c Thecarrlage or slide on which the knife Y is fixed is made to move backward and forward by the iiy wheel, Z), to which it is at tached by the connecting rod, d, and by giv-.

'inggit' as rapid a-m'otion as t-he machine the materials and work will allow-match splints can be made with great rapidity and in great'perfection and much cheaper than in any other way heretofore known, but to accomplish this the operator must see that his block of wood Vis well securedV in itsplace with the grain running lengthwise with thel box in which it stands, that all the partsof the machine are in perfect order and the knife is a good one with-a keen edge and made to operate upon-thewood as above described. Y p 1 Y f The use of the ratchet, the pawl, the lever, the drop bar, elbow, and cam is to make the machine feed itself. The position of the knife on the sliding frame and its motion give the proper stroke to the knife when it comes in contactwith theblock of wood intended to be cut into match splints. VThe same stroke may be given to a knife by a revolving inotion by fixing it to a wheel instead of securing it in a sliding carriage with a reciprocal motion or it may be fixed to a carriage made to move perpendieularly or horizontally upon one side so as to have the edge of the knifel lieV perpendicularly.

The invention and improvement consists in giving the knife a peculiar stroke and connecting 1t with the pointsorfgagegteeth above delscribed which marks oft'` and `separates the splints and `leaves them solid 'and of the rightpsize andfshape,Y V

In operating upon woodfor purpose of making match splints, substantially the same as herein described, it is essential that `the wood? be "cutfdiagonally, and" to eect this the operator can placefif he pleases a rowV of teeth ord-other dividers resembling those indicatedin'-thecdrawings ,Fig.` 4, at

Aproper distancesgfrom eachother and set in adiagonal position, in place of using the diagonal `knife as is i above lset forth and described or he may employ tworknives in `combination withI the gage Vteeth above described, the said knives 1being 'placed in` opposite-direction to and the edges ,facing Veach other diagonally.

Idonot claim as ,my invent-ionv any ofthe parts of thefaforesaid machine separately and il'idependentlyoftheir combination in said machine, nendo I claim as my invenvention or improvement any ofthe combinations in the abovemachine other than such as I have here speciallynamed and claimed. `But p y I do vclaim as my invention and improvement', i

The knife having a diagonal i drawing stroke in combination with the points used as 4gage teeth incuttng off land separating match splintsv by one operation as f herein described.
