MACHINE ron CUTTING AND sTRArenTnNrNe vnNEERs AND OTHER THIN Pincus or i j woon.

. Speccation of Letters Patent No. 3,359, dated December 4, 1843.

To all 'whommay concern t j j i Be it known that I, CHAUNCEY E. WARw NER, of the city, county, and State of New York, machinist, have invented and made and applied to use certain new and useful improvements in the arrangement, combina-` tion, and application of well-known mechanical means for thepurpose of cutting and straighteningiveneers or thin cards of wood to form the carcasses and tops or ccvers of small boxes suitable to various uses, for which improvements I seek Letters `Patent of the United States, and that the said improvements and the means of constructing and using the same are fully and substantially set forthand `shown in the following description `and in the drawings annexed to and making part of this specification,

j wherein- 20` said improvement; Fig. 21s a side elevation i Figure lis a plan of the arrangement 0f of the same, seen on the side A of Fig. la; Fig. 3, is a longitudinal skeleton section, of the operating parts, through the middle of the machine, `and the same letters and num-1 bers, as marks of reference, apply to` the same parts in all` the figures. l

B, B, are the frames, on which the opern ating parts are mounted;` C, C, are a fast and loose drum, by whichthe `machinery is connected to any competent motive power;

these drums are mounted on the shaft of the metal crank a; with pitman b, connects the crank, by joints, `with the metal knife carriage c, which is mounted, and works backward and forward, in metal guide slides d, d,

`the knife c being fixed on the forked part of the carriage c', with the edge of the knife toward the crank, andA a backing piece e. At the back. of the knife,'and immediately beneath, is a metal keeper spring e. The fore end fastened under the carriage and the lip in contact with the underside of the backing piece e. The knifecarriage, knife, andspring, work beneath the metal feeding box f, f, whichis mounted in a pair of metal cross standards, f1, `each having two arms yjf?, by which itis secured to t-he bed frame B, by bolts, in any convenient manner. Within the feed box f, is a stationaryv wood or `metal guide piece, or gage g, set tightly into the feed box. By the side of this the wood material 'y is placed, and steadied on that side, the lower end of the material being steadied between thereturn points It,

h, Fig. 3, of the t-ie clamps ,t'1, secured on the box f. The wood material, when within the feeding box, is impelled downward by unintermittent feeding motion, communi-` cated from the crankshaft a, by the eccentric 7c, which in its rotations, forces the outer end of the eccentric rod 701, against the pawl carriage Z, so as to carry that and the driving pawl m, on towardthe ratchet wheel g and give that an intermittent motion, any return of the ratchet wheel being prevented, by the fixed pawl n, set on a bolt that is secured by a nut through aslot in the carriage nl, on the side frame, `and by which bolt and slot the operation of the fixed pawl can be accurately adjusted. The operation of the driving pawl m, is` to` be adjusted by a slotted and screwed joint 2, l1n the eccentric rod 7c, and a strong spring` p, or any similar means, forces the pawl carriage Z, and pawl m, toward the shaft a as the eccentric la, draws back the rod 701 after similar wheel r3, on the second feed shaft, v

r4, and this carries the second feed roller 715, bot-h these shafts r, and rt, are mounted in bearings, on the standards f1, of the feeding box, and the bearings of the shaftr,

may` be madeto slide, and thereby be ada justable, to suit boxes of different sizes, the wheels r2 and r3 being also changeable.

` Outside t-he eccentric le, on the crankshaft a is a drum s, connected `py a belt s1, to a pulley S12 at the other end of the machine, mounted onta shaft s3, that runs in bearings, zil, u1, u?, and carries on it, between the bearings `the straightening roller t, which overlies the concave fixed guide fu.

A crosspiece u on the bearings al, carries a guide lip w, overlying the exit point, between the roller t and concave guide o, see the skeleton section inF ig. 3.` The feeding rollers r1, and 1'5, and the straightening roller t, are slightly serrated, or grooved, parallel with their axes, and are so adjusted in their positions, and distances, that the feeding rollers draw the material downward, and the straightening roller t draws each successive wooden card, or veneer, forward, at each successive motion of the knife in that direction, the card being cut from the material at the opposite motion and held between the spring a, and backing piece c1, until, at the return motion of the knife, the straightening roller t takes the card, and passes it out, under the lip fw, without crushing or breaking the grain of the material.

The modeof operating, and the product of this machine, is as follows: A piece of material, of the proper form and size to furnish the bottom, sides, and ends of a box, or the top, sides, and ends of a cover for such box, is to be sawed from a larger piece, so as to have the straight and clean grain of the wood, in the line of the intended length of the box; then, by any convenient means, so much of the angles are taken square out,

as will allow for turning up the sides andv ends of the box, or cover, and leave the endwise section of the material, in the form shown at a2, between Figs. 1 and 3. This wood material y, Fig. 3, is then put with the grain lengthwise of the machine, and pushed down, by the side of the gage g,

Y into the feed box f, until it passes between the return points 71, 7L, (Fig. 3) of the tie clamps c' ',which are so adjusted by the screws 2 (not named before) that they take any strain, caused by the cut of the knife e, on the material, and hold the material firmly, without any shock to cause distress, or pressure, on the rollers r', or b5 and, at the same time, the rollers are so adjusted in position, that they take hold of, and lead the material downward as the ratchet wheel g impels them around, at each intermittent motion given by the eccentric la, rod 7c', and pawl m, at each rotation of the crank shaft ci, which, at the same instant, forces the knife e, beneath the material, and by proper adjustment, makes it cut off a thin veneer, or card, like a slice, from the lower surface of the material, and at each return of the knife, the feed rollers bring downward a like thickness, to be cut off. The card or veneer, as each is cut, passes and is held, between the backing piece e and holding spring lip e', and is generally somewhat crooked lengthwise; but is returned forward until it enters the aperture, between the straightening roller t, and concave guide i), beneath, (see Fig. 3) where the roller t will take hold and lead it through, and the pressure between these, being the reverse of the crook given by the knife in the act of cutting, the card is forced to bend slightly, in the opposite direction, as it passes through, and on quitting the roller, the card strikes against the underside of the lip w, which may be so adjusted on the cross piece u, to the motion of the cards, as to cause each successive piece, either to drop into the hand of an attendant boy, or on to a table before him, whence they may be removed for completion elsewhere.

I do not intend to confine myself to the sizes and proportions of parts, shown in the drawings, but to vary the same, as may be required, to cut veneers, or wooden cards, for any specific size of box or cover; and, as I am aware, that knives, and other tools and appliances have been used, in cutting veneers for general purposes, I therefore do not claim, as my own invention,-any of t-he parts herein before described, either taken separately, or as applied to cutting any other description of veneers, than those for boxes, and their covers, as herein described; but

I do claim as new, and of my own invention, and as not having been before so used, for such purposesl. The mode, by which the operation of the tie clamps z', vl, z', and their'guide points 7L, z, is combined with the feeding rollers r', and 715, for the purpose of steadying the material, and feeding at the same time without distress to the feeding rollers, when such combination is applied for feeding the material, to cut veneers, or wooden cards, for boxes or covers, substantially as such mode or combination is herein described.

2. I claim the cutting of successive veneers, or wooden cards, for boxes or covers, and carrying them forward to the straightening roller, by the combination of the knife e, and keeper spring c with each other, and with the feeding apparatus, referred to in the preceding claim, when such entire combination is applied to the purposes above specified, including any merely mechanical variations, that may be substantially the same, in the means employed, and the effects produced.

8. I claim the use of the straightening roller t and concave guide i) beneath, for the purpose of drawing the veneers, or cards, out from the knife e, and lip e, and straightening the material, in its passage, when such use is applied in the manufacture of veneers, or wooden cards, meant to form boxes or covers; and I claim the combination therewith, of the lip w, adjusted to direct the successive veneers, or cards, in their exit from the roller and guide, and place the cards collectively together, substantially as herein described and set forth.

In witness whereof, I have hereunto set my hand and seal, in the city of New York, this fifth day of November', in the year one thousand eight hundred and forty two.
