Specification of Letters A Patent No. 860, dated `.'I11`1y52`8, 1838.

`To all'whvom t may concern.' i A Be it known that I, JAMES WYMAn, of` Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Machine for J ointingStaves for Barrels, Gasks, &c., whichis described as follows, reference being had to the annexed drawings of the same, making part of this-` speciiication.

A Figure '1, represents the frame of the `machine, made of sufficient size and strength to contain and support the several parts of the ,machine, hereafter described, Icomposed of six ports, mortised and tenoned into sills,

`or astout rectangular platform, two longitudinal caps, `and three cross ties, Valso mortised and tenoned together. The two center posts rise higher than the top of the frame and are connected `together on top by a tranverse cap a. t Y

B, B, two parallel ribs or ways fastened on top'of thelongitudinal'caps, at the inner edges thereof, over which the carriage moves.` y y c C,` the carriage formed of a rectangular shape being composed of kfour pieces of timber mortised `and tenoned, orgship lapped together, with a longitudinal piece c, mortised and tenoned, into the two end pieces in the center thereof andparallel with the two side pieces, having. on the under side of said center piece a rack d, Fig. l-into which a pinion e works for moving the carriage forc ward, which is fixed on an horizontal axle f, lying across the frame and revolved by certain gearing hereafter described. On the top of this carriage are four blocks b-(One at each corner of the carriage, having `a groove cut lon the inside of each, for the ends of guides to slide in hereafter described. Said grooves are formed by cutting the insideof each block obliquely from the upper The grooves, however,1 may be made rectangularly.-See Figs. 1, 2, and 7 Y D, D, two guides for moving the cutters to and fromI the stave in order to give it the required bilge or shape-the stave being fastened by dogs, or other suitable fastenings, on `the top of the center piece c, of the carriage and the guides arranged parallel to said center piece-"with the ends of the, guides placed in the groovesof theblocksl 1 before described-said ends being shaped to correspond with said grooves.` Each `guide 1s made concave on the front, or side toward the stave, .and of a, correspondin','g'` i shape therewith, and straight on the opposite `side or back-See D Fig. 2. y

E, E, E, E, cutters for shapingthe stave-- the stavebeing moved between lsaid cutters. These cutters are made ,similarL 1to.plane irons as atu Fig. 6 and are fastened to metallic stocks t' by screws-slotsbei'ng left in the cutters to set them as desired and two or more cutters being secured toA each stock. The stocksY are` fastened onu inclined revolving 4axles la, la, turned by pulleys ZJ, 'on said `axles and bands m, m1pas`sing around them to the main drum n Fig. l. Eachfaxle is Supported by an oblong frame o, 0,(ofjthree y sidesthe long Aside .rest-ing` `against the` guide by its gravity assisted by a spring p,

or weight and pulley ;-its lower short 'side` moving on a joint g `in a metallic box q resting on the center cross piece 05'?, ofvthe frame, near the center thereof said cutter frameV having an inclined position the same as the before mentioned axle. i Fig. 8. V t,

. The axle containing the cutters on one side of Vthe stave turns y in the frame-the y See also lower end of said axle being brought to a v point and made to turn` in a cavity formed in the upper surface of the lower side of the frame atv-and its upper end in a cavity of a regulating box s-screwed into .the side of said cutter frame. This regulating box extends abovethe frame and moves in an oblong mortise t t made in the cross cap of the main ,frame for guidingthe frame and V cutters. The other frame, axle, and cutters are formed and arranged in a similar manner, on the other side of the stave.`

F, Figs. 1 and 3, rack and bar for advancing to or receding from the cutterframe the concave guides in order to recede `from or advance the cutters toward the stave ac cording to the width of stave placed` there` on to be jointed. This is l, effected by fastening wedge shaped blocks fw Fig. 3 on the under side of said bar whichblocks as the bar is drawn forward come between inclined stops c Fig. 2 fastened on the top `of the car`- riage and behind the concaverguide D, and of course cause the concave guide to advance being contracted as the guide is advanced and extended as it is receded; said stops atl one end are staples inserted obliquely into the blocks b I) in which staples the ends of the springsare inserted: those at the other end are pins.

The inclined frame with the cutters rest-i ing against the guide will, by its gravity,

fall back from the stave and against the guide, aided by its spring. A similar rackbarfF wedge shaped blocks fw, stops Vy and springs a to those just described are arranged on the other side of the carriage for advanc v ing and receding the other guide.

Both bars are drawn forward or pushed back, for causing the wedge shaped blocksy on the under side thereof to perform theirl oflice, by means of two pinions Gr, G, on a.y crank shaft U turning in boxes in the end; of the carriage by handsaid pinions working'into the racks H of the bars F.

rThe pinion e for advancing the carriage before mentioned is fastened on an axle f.

passing through one of the caps of the frame,'on the end of which axle is a bevel wheel `I into which works another bevel wheel J on the end of an inclined shaft K having on its other end a cog-wheel M into which works a worm N on the end of the drum shaft S turning in boxes at the end of the frame. Y

The inclined shaft K turns in apertures or boxes in arms T projecting from the sides of the main frame. turning the cutters and advancing the carriage is made of any required diameter and is turned by a band Q passed around la small pulley V on the end of the drum leading to a driving pulley P on a crank axle R at the other end `of the Yframe turned by hand, or any other power.

The other end of the pinion axle f on which the bevel wheel is placed turns in the 'end of a lever L moving on a pin W inserted into the side of the frame for putting the pinion into gear with the raclr*it is put into gear by depressing the long end of the lever which raises the short end with the pinion axle and when the pinion is in gear it isthus held by means of a spring rest X. Fig. 4 fastened to the main frame which spring rest is pushed from under the axle by the carriage striking against its end VY when advanced as far as it is intended to The main drum n forgo and the short end of the lever is pushed down with the axle by a spring g Fig. l which thus throws the pinion out of gear. The carriage is then brought back by the gravity of a weight it attached toa cord j fastened to the carriage passing overV a pulley 0 at the end ofthe main frame and then over another pulley t. l

To joint a stave in this machine it is firstto be secured in the center of the carriage e by means of the dogs w lwthe pinions Gr at the end of the carriage are then turned which move the guides D by means of the racksY H, bars F, and wedge shaped blocks sition for jointing the'stave'. The. pinion e isthen put in gear with the rack 0l of the carriage Vcthe propelling power is then applied to the main axle R which it turns with the main driving pulley P, which, by means of the connecting belt Q, turns the main drum n and this turns the inclined axles 7c k and cutters E by thev bands m passing around it and said pulleys Z Z of said axles. The carriage c with the stave N o. l now advances and the cutters being pushed out toward the stave as far as they can Vgo by the convexity of the guides D, begin to cut the stave away at the point, and as the carriage advances the frames() containing the cutters recede from the stave by' following the 2 concavity of the guides causing the cutters to cut away the stave in'such a manner as to give it the required bilge bevel and taper which of course will correspond with the concavity of the guides; when the carriage has advanced as far as to bring the cutters in the greatest concavity then the greatest bilge will be vformed and now the cutters gradually cut away more of it toward the other end Vby the gradual swelling of the guides toward the stave.

When the carriage has advanced as far as it is intended to go it comes in contact with the spring rest Y pushes it from under the pinion axlev Y f which instantly falls and throws the pinion e out of gear with the rack al by its gravity and the action of the spring g above the lever L. The carriage then runs backby the gravity of the weight hat the end of thecord z fastened to the carriage c. The jointed stave is then removed and one not jointed secured in its place. The pinion is again put into vgear with the rack ofthe carriage and the operation is repeated in the manner just described.

VThe invention' claimed by me the said JAMES WYMAN, and which I desire to secure by Letters Patent consists- Y l. In the before Vdescribed mode of jointing staves by passing them between revolving cutters arranged in frames moving onk izo seo B the mannerl herein represented, or in any other substantially the same in principle.

JAMES WYMAN.
