To all whom t may concern.'

Be it known that I, IsAAc JUDsoN, of the city and county of New Haven and State of Connecticut, have invented a new and useful improvement in machines for dressing the convex and concave sides of staves to any required curvature by means of two sets of rotary cutters turning in parallel planes, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

The nature of my invention and improvement consists in combiningand arranging two revolving rings, or wheels, having cutters on their opposing surfaces or sides next cach other for shaving the stave transversely Y and simultaneously on its inner and outer sides producing a stave the cross sect-ion of Which is the segment of a circle the diameter of which is to be greater than the diameters of the said rings, or wheels (the curve of the stave beingvariable at pleasure according to the sizes of the different kinds of casks for which the staves are intended),

by changing the position of the stationary guides and feed rolls, and of thecutters on the parallel rings or wheels so asto change the angle of the position of the stave with the plane ofl the rings, or wheels, which forms the base of a right angled triangle, or section of a cone, andV the axes of said wheels which forms theperpendicular of said right angled triangle, or the axis of a cone the straight line in which lthe stave moves toward the cutters being the hyp'otenuse` of the right angled triangle or the inclined side of the cone (represented by line m in F igs.A

6 which line ismade changeable at pleasure in order to change the degree of curvature of the stave as stated. The angle of the side of the cone with its base being increased when the degree of the curve of the stave isk to be decreased and when the angleof the.

cone is diminished the degree of the curvature of the stave is increased.

This principle of'introducing a stave, or

other piece of wood, obliquely between two series of'revolving cutters at any'required4 angle with the planes ofthe wheels or rings carrying the cuttersfor the purpose of cutting the stave or piece of wood transversely to the segment of any. given circle corresponding with thatv of the intended cask,

`the machine.

constitutes my principal invention land im? provement.- v

The nature ofthe second improvement consists" in a new arrangement oftwo mov able fluted or grooved feed rolls for driving the stave past,y or between the revolvingy rings, or wheels of cutters, said rolls being held together by a spring or other means so as not to give to the stave any specific direction leaving it to be guided by stationary rests of short lengths so as to a'ccomimdatey the crooks and winds'of the grain of the `v'v'ood' to the position of the cutters.

This form `of cutter *is` preferred; its position on the wheel may be changed at pleasure, so as to correspond with any changeof position of the` stave for `producing-the vari ous eurvatures of the inner side of the stave. The gouge shaped cutter, represented in F ig. l, is securedto the wheel in the same way. This cutter is found notito answerso good a purpose in all cases as some otherA forms that have beentried, but to remove the l surplus 'material itanswers very well.

quired form,and may be secured tothe wheel in any convenient way and at the required angle vfor producing the desired result.

H, `is a revolving ring, or rim, for carrying'the cutters that cut, form, andshave the convex side of the stave. The axes of the ringand` wheel coincidegbut their vertical planesdo not; they are,` however, parallel.y

The ring is set back from the wheel the re- -quired dist-ance to form the necessary space between themfor the .passage ofthe staves obliquely between the cutters at any required angle with the planes of the ring and wheel. The ring has no axle or shaft; it is supported by, and turns against, the peripheries of a number of antifriction wheels I, whose axles turn in boxes connected with castings fixed to the frame. The ring is sustained upon the 'peripheries of these ant-ifriction wheels by means of a circular groove made in the periphery of thering in which the said antifrictionwheels turn and which preventv the ring from having any side motion dur# ing its revolving motion.` It is turned by means of a flat endless band passed around it` and'leading to the driving power. Or by means of an endless round bandK let into a corresponding groove made in thepperiphery of the ring anda similar groove made in a pulley ZL on the driving., shaft. The cut-f ters of this ,ring are-made and arranged in the same manner 'as 'those above described for the wheel. f l

M, M, are two short right angled restsf'or guides, fastened to the frame by means of segmentl mortises and set screws.` The mortises are made in the horizontal portionsv of the rests or guides. The verticalportions constitute the guides against which the stave to be dressed is propelled. The faces of these guidesvare in a straight oblique line.V

This line when continued'until it intersects a line drawn through the axis of the wheel' and aline drawn through theV base of the z wheel will form the hypotenuse of a right angled triangle or the side of av section of a cone-fthebase of the triangle corresponding with the base of the wheel, and t-he perpendicular correspondingwith'the' axis of the wheel.` In Fig. 6 these lines are represented at m, bfc-fm. being theV hypotenuse, b, thev base, and c the perpendicular. In dressing staves for casks of Various diameters the line of the guides must be varied.-l To cut the stave the segment of a larger circle the line ofthe guides must be changed so as to diminish its angle with the base.

A contrary result: takes place when the lstave is to vbe`dressed for a smaller Cask.

This is effected by simplyV unscrewing the set screws, s, and moving, the guides to the required position, and again making them fast. The staves are propelled forward to the cutters by means of twofeed rolls N, N,

whose axes are nearlyparallel and vertical, and between which the Vstave is placed. These rollsare above theframe and their shafts O, O, extenddown through theframe to an adjustable segment plate P turning on a center i in the frame; Vin which plate the lower ends ofthe shafts are stepped or placed and adjusted or moved to the right or left in the ,arc of a circle by moving said segment plate whichfis held in any required positionby a catch-Q, attached to the `frame 'and dropped into anotch or hole in the segment plate. The upper ends of the shafts are loose and'have `a swing motion to the right and left and are borne toward each other by a spring S which embraces the,

shafts. i i

The shafts are thus placed `for the purpose of allowing the feed rolls t-o accommodate themselves to the crooked forms of the` staves to be dressed. The shafts` areturned by means of cog-wheels T 'I2 xed to them which are geared together, and to an inter-` mediate cogwheel T3", which is geared `with a pinion T4 on a vertical axle i on which there turns alarge bevel wheel V that works into a smallbevel pinion W on a Vhorizontal shaft X turning insuitable boxes in the frame, there beingv on said shaft a `pulley VY aroundzwhich is placed a cross band Z leading around a pulley e on the yaxle c of vvthe wheel of cutters.f

gV is a loose pulley on said shaft of the` usual form, arrangement, and operation.` 79 and g aretwo antifriction rollers `for bearing the stave against the guides.

j and 7c are springs for extendingthe rollers outward toward the guides.V When a stave' is inserted between the ,guides and rollers the springs jandlc contract to allow'` the vrollers to recede. In Fig. 1 the rollers p and g are represented'as extended solas` nearly to touch the guides-no stavebeing represented in the machine.

When a stave `is Vto be ldressed it is placed edgewise upon the frame with one` end between `the feed rolls NI-the machine being put in motion, the feed rolls `propel the` stave between the guides and bearing rollers to the cutters on the opposing 'faces of the wheel and ring and in passing between the cutters it is shaped and dressed smooth-concave on one side and convex on the opposite side. Another stave being inserted between the feed rolls and propelled forward in the same manner strikes against the stave next before it and propels it through the space between the wheel and ring. In this manner the operation of the machine is kept up.

The stave or other piece of wood may be dressed to a concave or convex form on one side only, by introducing it in an oblique direction to either the wheel or ring of cutters used singly.

What I claim as my invention, and desire to secure by Letters Patent, is-

The manner of arranging the wheel and ring of cutters in parallel planes forming a space between them for the introduction of the stave to be dressed simultaneously on both sides-concave on one .side and convex on the other, and to any degree of curvature required, according tothe position of the guides in relation to the cutters on the wheel, and ring, as herein set forth; the stave, or other. piece of wood being introduced obliquely between the two series of revolving cutters at any required angle with the planes of the wheels, or rings, carrying the cutters, for, the purpose of cutting the stave or piece of wood transversely to the segment of any given circle corresponding 'with that of the intended Cask, or barrel',

of which the stave is to form part, changeable at pleasure by changing the position of the stave, the feed rollers being made to swing to the right and left in the arc of a circle for the purpo-se of accommodating themselves to the irregular shapes of the pieces of wood to be dressed into staves.
