GEORGE EDVARD COOKE, OF OLARKSVILLE, TENNESSEE.

SHINGLE--SAWING MACHINE.

Application man August 14, i835.

To all whom it may concern;

Beit known that I, GEORGE EDWARD COOKE, of Clarksville, in the county of Montgomeryl and State of Tennessee, have invented a new and Improved Shingle'Shaving Machine, of which the following is a full, clear, and exact description.

My invention relates to machines more particularly adapted for shaving rived shingles to a iinsh and with a correct taper from heel tov point, and adapted,also,for shaving staves and shaping pieces for wagons, agricultural implements, &c., and the object of the invenvention is to promote the effectiveness of machines of this character by providing simple eiiicient means for preventing the shingles or pieces from slipping under the action of the shaving-knife; also means for discharging the shaved shingles or pieces from Athe machine, and for resetting the discharging devices, and all worked automatically by the reciprocating sash.

The invention consists in certain novel features ofconstruction andfcombinations of parts of the shaving-machine, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure l is a rear side elevation of my impnoved shingleshaving machine arranged in the preferred form as a doubleacting 1nachine. Fig. 2 is a plan View thereof, partly broken away and in section.

Serial No. 171,414. (Nomodcl.)

pieces placed one on cach of the beds D D of the machine will be shaved to a proper taper or shape at each complete reciprocation or forward and back stroke of the sash, which will be .moved in the frame A by any usual or approved mechanism, not necessary to show or describe.

The shingle-beds D are pivoted on pins d d to the frame A and in openings of its top, so that the sash B slides over the beds, and the beds are held up to support the shingles as the knives C act on them by means of heavy tappcts D', which are Vfixed to shafts D2, journaled in the frame A.

On the shafts D2 are fixed the disk-wheels D3 D", cach of which is provided with two pairs of pins, el d2 d d2, and also with diamctrically-opposite peripheral stop-shoulders d cl.

To the frame A of the doubleacting machine is pivoted atb the lower end of a lever, B, which at its upper end has a pin-and-slot connection, as at b', with the sash B, so that as the sash is reciprocated, the lever B will be rocked. As seen best in Figs. 1 and 2, there are pivotedat their inner ends on a pin, b2, in lever B', the inner ends of the independently-acting bars B2 B,which extend opposite ways, so that the two hooks b3 b4, formed by notches cut in the lower edges of the bars,will successively engage the pins d d2 as the lever B is rocked to give intermittent half-revolutions to the shaft D2 and their tappets D', for raising the shingle-beds D and letting them fall at the proper times, as hereinafter more fully explained.

To the levers B are pivoted at e the oppositely-extending bars i" Ewhich have snp IOO port at their outer ends in slots of bracketplates E, xed to the frame A, and are provided, respectively,with the hooks or should ers e which are adapted to lock against the lowermost shoulders, d3 or d*, of the disk-wheels D3 D4 to lock their shafts D? and tappets D' against forward movement,and simultaneously with the engagement of these hook-bars E' E2 with the disk-wheels, as aforesaid, a pin or stud, d5, on the disk-wheel presses back a spring-pressed pin, e3, held to the frame A, and passes above said pin,which then springs out and prevents a back movement of the diskwheel, which thus held against rotation both ways to lock the corresponding tappet, D', in upright position to support the bed D above it against the downward pressure of the knife C as'it shaves the shingle or piece held on the bed by the roller F. Springs E3 are attached at opposite ends to the opposite bars B`2 E' and B3 E2, and act to draw the bars B2 B3 into engagement with the pairs of pins d' d2 on the disk-wheels D3 D4, and also to engage the shoulders e' e2 of hook-bars E' E2 with the peripheral shoulders d3 d* of the disk-wheels.

There is a roller, F, mounted in verticallyspring.

movable bars f, fitted in brackets f' f', held to the sash B in front or in advance of each of the knives C, a platespring atf2 being pivoted to carry the roller downward with a pressure which may be regulated by a screw, f3, threaded through the top crossbar, f above the spring and swiveled to the center of the (See Fig. 7.) The roller F may be pressed downward by spiral springs fitted above the boxes F, if preferred. These'presserrollers F hold the shingles down to the beds D directly in front of the cutting-edges of the knives C, and yield as they advance toward the higher ends of the beds D,which are held by the tappets D' at a proper incline to cause the knives to give a correct taper or shape to the shingles or pieces. (See Figs. 3 and 4.) The presser-rollers thus hold the shingles so that if warped or twisted when laid on the bed they will be pressed iatas they are shaved, and when finished will have a uniform thickness across their entire width at any place from heel to point. The presser-rollers F also coact with the yielding plates or guards H in preventing the forward ends of the shingles from escaping from a thrust or end bearing should the shingles or pieces be warped lengthwise,-`and as next explained. When theshinglebed D is held fully up at its free or forward end by the tappets D', its face at said forward end will lie a little below the top of a thrust-block, G, fixed to and across the top A' of the frame A, so that a shingle lying flat at its forward end on the bed D will be pressed by the knife C against the shoulder g of saidthrust-block during the entire operation of shaving the shingle, but should the shingle or piece be curled upward when laid on the bed the forward end of the shingle or piece will bear against the guard H, as indicated in dotted lines in Fig. 3, said guard H being inclined v are connected by a cross-bar, h2, at their back,

or outer ends. The side pieces, h'h', are fitted by tongues to rabbets or grooves in the under. sides of guide-bars H' H', fixed to the frametop A', so that the guard H and its frame h h' 71? may slide forward and back on thetop A'. A spring, H2, is placed on a bar or rod, ha, fixed to guard Hand supported loosely in a post or bracket-piece, if, fixed to the frame-top,v the springbeing between. the guard and said post, so as to throw the guard toward the adjacent bed D, and until the inner ends of the said pieces h' strike the back edge of the thr'ustbar G. The inner ends of the pieces h' preferablyare extended at their lower parts into under-cuts or notches in the vbar G, so as to more effectually resist the tendency of the guard H to rise by the pressure of the shingle or piece on it. At each side ofthe guardframe is pivoted ati' a lever, I, which has a shoulder at z" adapted to look behind the frame when the guard H is pressedinto normal position bythe spring h, the lower face portion of the guard then being even with the edge or shoulder of the thrust-block G, against which the forward end ofthe shingle or piece is pressed by the knife C.d A spring, I', connects the outer ends of the levers I I and draws their shoulders i' iu behind the guard-frame. rIhis locking action of the opposite levers I I on the frame of the guard prevents the guard from being forced forward by the upturned end ofa warped shingle or piece being shaved and which may happen to rest against it. When the sash B has advanced sufficiently to cause the roller F to press this end of the shingle down flat to the bed D, the shingle then will bear against the edge shoulder g of the thrust-bar G, and about at this time trip-blocks I2 I2, xed to opposite side bars ofthe sash B,`will act on the inner ends, if, of the opposite levers I I to disengage their shoulders i' from the guard-frame and permit it to be forced back by the contact of the roller F with the guard H as the sash completes its stroke in that direction to carry the knife C clear through the shingle or piece, and as shown at the left-hand end of Figs. 1, 2, and 3. As the rollerFrecedes on the returnfstroke of the sash B, thevspring Hz will force the guard H back to its normal position, and the spring I' will set the shoulders t" of levers I again behind the guard-frame, ready for the' next stroke of the sash toward the guard. It will be seen that the guard H, with the roller F,fornns an effective means to prevent forward slip of the shingle or piece from the thrustbar G on the frame; hence the action of the shaving-knife C on every shingle or piece will IOO lIO

be positive, andthe shingles or pieces will not stick to the knife and clog the machine. The knife-bed D has inclined rabbets d d at opposite sides, which allow the trip-blocks I2 to pass along the bed on their way to the levers 1,(see Figs. 2 and 8,) and the opposite side bars of the sash B are or may be connected by arching erossbars or bridge-pieces Bt, which may move over the guard H and its connec tions as the sash B reciproeates After the shingle or piece. has lbeen shaved the bed D is allowed to swing down on its pivots (ZT by the turning of the tappet D', which had supported it, and, as 'shown at the left-hand side of Fig. et, and just asthe bed drops the shaved shingle or piece is automatically discharged from the machine by devices next described.

Across the machine, and about under the pivots CZ of the `shingle-bed D, is journaled a shaft, K, to which are fixed the shingle-discharging iingers k k, which project through or are adapted to slot-s ZS (Z8 in the bed D and coinciding slots d fZ in the top A' of frame A. About at a right angle to the fingers kk is fixed to the shaft K an arnnt', which is adapted to be set over a spring-pressed trip-pin, L, fitted to slide laterally in the machine-frame. To the shaft K also is fixed the bent arm It, against the hooked extremity of which the bent end m of a pnslrrod, M, is adapted to act for setting the arm It' over the trippin L, and thereby forcing the fingers k 7c back into the slots d" d of the frame A, as shown in Figs. 2 and 3, or, in other words, set-ting these ngers in position ready to deliver a blow on the back end of the shaved shingle or piece to discharge it from the machine, the force of which blow is determined by the tension of a spring, N, which is coiled around the shaft K and fixed at one end to the bent arm m, and at the other end to the frame A or its top A'. The spring N thus is the prime mover ot' the discharging iingers. The push-rod M is supported so as to slide in a suitable guide-eye, m', on the frame, and at its forward end is connected to a bolt end, m2, which is threaded into the bent end o of a bar, 0, and receives a. nut, in", outside said end o of the bar, which provides for lengthwise adjustment. The other end of the bar O is pivoted to the lower end of a lever, P, which is pivoted atpto the machine-frame, and a spring, Q, attached to lever P and the frame A draws theY lever and the push-rod M back after they have been forced forward to set the arm ZZ" over the trip-pin L and out ofthe way of the arm k2 ofthe shaft K as it il'ies back when the discharginglngers k are released by withdrawal of the trip'pin L from beneath the arm 7c', as hereinafter explained. An arm or pin, J, fixed to the sash B is adapted to strike the top of the lever P on the return-stroke of the shaving-knife C, to force the rod M endwise against the arm 7c on shaft K for setting the arm k' over the trip-pin L. As best seen in Figs. 9, l0, and l1, the trip-pin L is fitted loosely in the frame A and in a bridge piece or bracket, L', fixed to the frame, and on the pin L is fixed a disk or plate, L2, in which is fixed a pin, Z, which acts by its inner end against the face of the teeth i' of' a circular rack, R, which is fixed to a ratchet-wheel, R', which is placed loosely on the piln L, and has peripheral teeth r', which are engaged by a pin, s, in one end of a connecting-rod, S, which is pivoted at its other end to a lever, T, which is pivoted at t to the frame A, and has at its upper end a slot, Z', so arranged that a pin, U, on the sash B may enter the slot for throwing the lever 'li forward and back for actuating the rod S to impart motion to the ratchet-wheel Rin the direction of arrow l, and thereby causing each tooth r of rack It to thrust out the pin Z, and consequently the trip-piu L, to withdraw its inner end, Z', `from the arm 7i" of shaft Kto allow the spring N to throw the fingersc forward to dis charge the shaved shingle or piece. The pin Z projects also from the outer face of the plate Ll and enters a hole in the bracket L', so as to prevent the trip-pin L from turning axially in its bearings, and thus holding the beveled portion of its inner end, Z', downward, so that the arm k' of shaft K will strike said beveled part of pin L and force the pin outward to allow the arm to lodge on top of it to hold the fingers 7c set back when and after the puslrrod M has acted on the arm k2 of the shaft, as hereinbefore explained. A spring,V, held to the tri p` pin L, or it may be to the bracket L', acts between the plate LZ and the bracket to force the trip-pin L back into position for engaging or supporting the arm 7i" ot' shaft K, and a spring, V', held to the frame A at one end acts by its other end against stop-pins r2 set in the inner face of ratel1et-\vheelRto prevent back move ment of the ratchet.

At V is shown a rigid arm or plate, which is fixed at one end to the frame A, and at its other end carries a pair of pins, w w, which stand one at each side of the connecting-rod S to guide it so its pin s acts properly on the ratchetwheel R, and a spring, V2, is fixed at one end to said arm XV, and acts by its free end to hold the rod S up to cause its pin s to engage the ratchet-wheel.

The arrangement of operating-levers of the singleaeting machine differs somewhat from that shown in the double-acting machine. By referring to Fig. 9 it will be seen that the main lever B', which is connected to the sash B, is pivoted at b a little below its center to the frame A, and' its lower end is connected by a rod, B, with the lower end of a lever, B, which is pivoted at b to the frame A, and the lockbar E' and lever B2 are pivoted to the le ver l above its pivot b to give the required movement to said lever and lock-bar in open ating the tappet-shaft Dl to lower the shinglebed D and raise and lock it, as hereinbefore explained.

I will now describe the continuous operation with more special reference to the single-act- IOO ing machine,as follows: In the positions of the parts shown in Fig. 9 the sash B is quite at the extreme limit of the back-stroke, and the pin or arm J is acting on lever P to force rod M forward to set the arm 7c ou shaft K over the trip-pin L and throw the lingers 7c back onto the pin L, and the outer hook or notch, b", of bar B2 has just drawn the wheel D around in direction of arrow 2 to move shaft D2 for lifting the shinglebed D to its highest position by the tappct D', at which time the shoulder e of bar E had met thel shoulder d" of wheel D, and one stop, d5, on said wheel hadlodged on the spring stop-pin e3 todoublelock the tappet, so it firmly supports the bed `D, as hereinbefore described, and the pin U on the sash had passed by the lever T after having moved it to the position shown for tripping the fingers sinto action for discharging the last shaved shingle or piece.. The next shingle or piece to be shaved now is laid on the bed D with its forward end abutting the thrust-block G or guard H, and as the sash B moves forward in direction of arrow 3 to carry the knife C through the shingle or piece the pin J will leave the leverP and al. low the spring Q to drawback the rod M from the arm k2 ol' shaft K, and the lever BG will throw thebarB2 forward, so thatits inner notch engages the opposite pin, d', on wheel D, ready for the next return or back strokeof the sash, and the shoulder e of bar E will be moved forward away from the shoulder d* of wheel D to allow the wheel to be turned in direction of arrow 2 at the proper time. As the knife C passes through the shingle or piece, the roller F and guard H coact, while the guard is pushed forward, as hereinbefore fully described, to prevent slip of the shingle or piece, and the pin U engages the slot t of lever T to rock the lever and throw back the rod S and set its pin or tooth s into the next notch or tooth, i", of the ratchet-wheel R', and after the knife C has completed its cut through the shingle and the motion of the shaft is reversed the guard H will follow the roller F backward to the edge of the thrust-block G, and the bar B`Z will draw on the pins d disuecessively by its notches b b" to turn the wheel D3 in direction of arrow 2, and thereby turn the tappets D, to allow the shingle-bed D to fall, as at the lcft-hand end of Fig. 4, and during this falling movement of the bed the pin U on sash B will again engage the lever T, to throw its upper end backward to the position shown in Fig. 9, and thereby carry the rod S forward to turn the ratchet-wheel B in direction of arrow l the distance of one ot' its teeth i" and 1', and thereby force the trip-pin L outward, to withdraw it from the arm la of shaft K and allow the spring N to throw the fingers c backward and strike the back end of the shaved shingle or piece lying on the lower bed, D, and discharge it from the machine, as indicated at X in dotted lines in Fig. 4. As

the back-stroke of the sash B is about half completed, the tappet D will again begin to assume an upright position with its other end upward, and as it fully raises the 'shingle-bed D the wheel D3 will again be doubly locked by the stops e di and shoulders d e', to hold the bed D in place, and as the sash completes its .back-stroke the pin J on it will again push back the lever P to thrust the rod M forward against the arm k2 of shaft K for setting the arm 7c over the trip-pin L, and all is ready for the next forward `stroke of the sash to shave the next shingle or piece laid on the bed D.

In the double-acting machine shown, the one trip-pin J on sash B acts on both the settinglevers P P of the discharging-fingers 7c at opposite -ends of the machine, and the sash has a pin, U, at or near each end, which, at the extremes of the strokes of the sash each way act on the levers T to trip the shingle-discharging fingers k into action at each end of the machine as the beds D fall when their respective tappets D are turned to horizontal positions, it being understood that onel shingle or piece is being shaved at one end ofthe machine while another shingle or piece is being discharged at the other end of the machine, a shingle or piece being shaved and discharged at each hal f-stroke of the sash. The one lever B aetuates the opposite pairs of bars B2 E B3 Ewith like effect on the disk-wheels D3 D4 and their respective tappets, as hereinbefore described for the single-acting machine, and, if desired, the lever B may be extended upward at one end of the double-'acting machine to connect with the sash, as shown in the singleacting machine, Fig. 9, and in which case the lcverB in Fig. l will not be connected with the sash, as therein shown,and the second pair of operating-bars, E2 B3, will be connected between their operating-lever and the lever B', which connects with the end of the sash, as will readily be understood.

It will be seen that all the operations ofthe machine are automatic and positive, and that the working capacity of the machine is limited only by the expertncss of the attendants who feed the rived shingles or pieces to it.

A spring pressed or yielding bar may be mounted across the sash B as a substitute for and mechanical equivalent of the roller F; but

-the roller is preferred, as it will operate to hold the shingles to the bed D with less friction than would the bar. It is evident that two or more of the tappets Df may be fixed to the shaft D2 under each of the shingle-beds D to support the beds, and the setting and tripping mechanism of the discharging-lingers 7c maybe arranged for one bed D of the-double-acting machine at .one side of the machine-frame and for the other bed D at the other side of the frame, and the trip-pins on the sash will be correspondingly arranged to throw the levers P to trip the dischargingfingers, substantially as above described, and the frame of the double-acting machine may IIS ISO

be lengthened, so that the ends of the sash will not run past the ends of the frame, as in Figs. 1 and 5, when the machine is operated.

As before stated, the maehineis adapted not only for shaving shingles, but is adapted also for shaving staves and for shaping pieces for use in building wagons, agricultural implements, and in other work.

It is obvious that the mechanism for setting the arm k of the shaft K over the trip-pin L, and for tripping the arm from said pin may vai-yin its details from that herein shown and described, as other means may be devised for securing these results by or from the action of the reciprocating sash.
