IMPROVEMENT In MAcHlNEs Fon C Rozm'e AND HowEnNe BARRLS.

Specification farming part of LctlersPatent No. 80.481, dated July 28, 1868.

To all whom it may concern: Be it known that we, EDWARD HOLMES and BRITAIN HOLMEs,of thecityofBuff-alo, county i of Erie, and 'State of New York, have invented a certain new and Improved Machine for Cham- 1 fering, Howeling, and Crozing Uasks; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, maknga 'part of this specification, in which- Figure I is a sectioualelevation. Fig. II is a top plan view. Fig. III is a plan view of the radial adjustable arms. Fig. IV is a transverse vertical section. Fig.-V isa diagram,

' showing the cutter-head and the end of a stave.

v The nature ot' our invention consists in the combination of a guide-rest with acutter-head carrying chamfering, crozing, and howeling cutters in such manner that the action cf said cutters will be gaged from the exterior surface of the cask, and Athereby a true and uniform `chamfer, croze, and howel obtained, as will hereinafter more fully appear.

f Letters of like name and kind refer to like partsjin each of the gures.

The main shaft, which'supports the cask, is

1`- represented at A@ It revolves in bearings a a2, one of which is located nearits center, and

the other supports one end of the shaft, the opposite end overhanging upon one side ofthe machine, for the purpose hereinafter set forth. Brepresents arectangular frame constructed of suitable timber, upon which frame all the operating parts of the machine are supported.

The overhanging end of the shaft A is made hollow, as shown in Fig. I. i y

C G represent two sets of radial arms made fast to the shaft A, each series composed of in and out-toward and from the center of the shaft by means of the sliding cross-heads D, to which the sleeves C are connected by the rods d. The crossheads D are made circular,

' and slide horizontally upon the outside of the shaft A. At the several points where thc rods d are attached the cross-heads have eccentric s,lots,through which the connecting-bolts pass, and by which means said bolts may be adjusted at different distances from the center, nc-

cording to the size ot' the cask intended to be held by the said sleeves or arms. Each circular cross-head D is, by means of' a set-screw, d2, connected to a uut, E, `upmon the inside of th'e shaft, the set-screw passing through a slot.

cut longitudinally in the shaft A for that purpose. Hence neither thecross-headD nor the n ut E is allowed to revc ve around the shaft,

butboth may move longitudinally. The crossheads D being located in the middle `between the two series of arms, it-is necessary that, in order to expand or conti act both series of arms simultaneously, the .cross-heads have to move also simultaneously, but in opposite directions'. This is accomplished by means of the rightand-left screw F, passing through and-operating both nuts E, as is clearly represented in Fig. I. 'A hand-wheel, F', upon the end ofthe shaft is connected to and operates this screw F ina manner to expand or contract allV the radial arms C C simultaneously. New, inorder to properly center and secure the cask upon these arms in position ro receive the chamfer,

croze, and bowel, the hand-wheel, and hence theyscrew F, are first turned in a direction to contract the arms C', then the cask is placed over the end of the shaft and upon thearms,

vand the screw is :evolved` in the opposite direction, by which means the arms expand and gradually raise the cask until all the arms take hold of the insideof the cask and keep it h'rmly in position. Whilethe cask is raisedas aforesaid the edge thereof whichv is contiguous to the bearing a2 is retained in the proper vertical position by means of the top and bottom guides, g and g', so that when the c-.lsk is firm! y connected to and held by the arms its axis will be coincident, or nearly so, with the axis of the shaft.

H represents the cutter-head, to. which all the cutting-knives are connected which are required for chamfering, crozing, and howeling theends of the cask.v` This cutter-head is represented in detail in Fig. V, together with a them upon the end of the stave are represented by corresponding figures. ly represents the chamfering-knives and the chamt'er upon the` stave; 2, the croZing-knfe and the croze upon the stave, and 3 thehoweling-knife and the bowel upon the stave. The cutter-head is attached to the overhung end of the shaft H', carrying the driving-pulley h2, by which it is revolved. The shaft H' is supported-upon a swinging trame, I, composed of two upright standards, their lower ends being hinged to the frame B and the upper ends forming bearings for the shaft H'. The purpose ot this'. swinging frame and its operation willbe. .hf-reinafter described.

re resen s r t as i con- J p va est,77 we call t It sists cfa curved piece ot'metal, which is hinged in the middle, its ends projecting toward the center ofthe main shalt A. This rest is supported upona swinging upright lever, K, which is hinged tothe main frame. The object ofthe rest J is to govern the action ot' the chamfering,

crozing, and h'oweling cutters uponthe cask.

Theinsideofa cask generallypresents a very irregular and lbroken surface, owing to the unequal thickness of the staves employed in its formation, while the outside of the cask, owing to the ett'ect of the hoops which secure it, always presents a smooth and uniform surface. Consequently the depth of cut requires to be l gaged from the exterior surface ot` the cask. l The rest is kept in'close contactwith the exterior surface of the cask as it revolves'by the action of a weighted lever, N, which 'is-an extension at right angles from the rest-lever K.

By means of a lever, L2, connecting ,with the frames I'and K through the rods L L', the frames I and K may be thrown to or from each other, as desired. `When thrown toward each other the lever L2 will occupy the position shown in Fig. IV, in which position, owing to its joints With the levers L L' being-in line with each other and with the joints which connect.

said levers to frames I and K, said frames I and K will be securely locked and held together, and Will oscillate upon their common axis as one frame. y Elencethe rest J, in following the'external surface of the cask, will cause the cutter-head to follow parallel thereto,

so that the charmfer, croze, and bowel willleave` times the casks have not a true circular form and cannot be centered truly upon the shaft A, owing tothe different thickness of thel staves. The cutter, it' supported in stationary the rough edge caused by the laction of the' chamfering-cutter.

O P Q represent gear-wheels, by means of which motion is given to the shaft A; and R is a friction-clutch, and Sthe main drivingpulley, which furnishes the required motion.v

The operation of this machine is as follows:

The requiredvnumber ot' staves having been formed in the shape of a cask, and the, ends thereof firmly held in place by the truss-hoops and le-veled,the sameare placed upon the arms C C', gaged b v the guides g1g', and by means of the expanding arms firmly attached to the shaft A, as above described. Then, by means ofthe compound levers L L' L2, the cutter-head and rest are brought together in such manner that the cutter-head comes in'contact with the inside and the rest bears upon the outside of the stave. The cutter-shaft being set in motion, theknives upon the cutter-head will cham` fer, croze, and howel the end ofthe stave, and the leveling-knife upon the lovvei` end ot' the rest cutoff the sharp edges formed at the ends of the stave by the chamfering-knife. The set-screw m regulates the depth of cut the cutting-knives are required to make in the end of the stave, and keeps the axis of the cutter-head a certain distance from the rest. The main shaft A being slowly revolved, the staves are one after the other fed to the cutter. One whole revolution ot the shaft is sufcient to finish one end ofthe cask. Then the arms C C' are contracted, the cask turned around, and the other end finished in like manner. A,

What we claim as our invention, and desire to secure by Letters Patent, is-

The combination ofthe cutter-headH, supported by the swinging frame I, with the rest J, supported by the swinging frame K, oscillating upon a common axis with the cutterframe, when said frames K and I are provided
