IMPROVEMENT IN MACHINES FOR cRozING AND CHAMFERING sr'Av'Es Specification forming part of Letters Patent No. 36,186, dated August 12, 1862; reissue No. 5,626, dated October 2l., 1873; application tiled May 29, 1873.

To all whom it may concern:

Be it known that HENRY WILBE, of .the city of Newark, county of EsseX and State of New Jersey, did invent certain Improvements in Machines for Orozing and -Ohamfering Staves, of which the following is a specification:

The invention relates to that class of machines in which the cylinder of staves to be dressed is secured between two chucks, and slowly revolved, so as to bring the successive portions of each end of the stave-cylinder in engagement with rapidly-revolving dressing tools or cutters.

In the accompanying drawings, Figure l is a perspective view of the improved machine; Fig. 2, a longitudinal vertical section thereof; Fig. 3, a transverse vertical section in linex, Fig. 2, on an enlarged scale. Fig. 4 is a longitudinal vertical section of one of the heads or mandrels, and thebearing thereof Fig. 5, a vertical section ofone-halfofthe circular bearing of one of the chucks or revolving rings which receive the end ofthe barrel. Fig. 6 is a transverse vertical section in line y y, Fig. 2. Fig. 7 is a face view of the cutters or dressing-tools. Fig. S is an edge view of the same.

Like letters of reference designate like parts in each of the figures.

A is the main frame of the machine 5 B B, bed-plates, movable lengthwise of the frame. C O are bearings for the ln'andrels or cuttershafts e e. These bearings are connected by tie rods or bars ff, and slide between transverse ways b b secured to the bed-plates B. g g are two sets of cutters, mounted, respectively, on the mandrels e e; and e are driving-pulleys on said mandrels. D D are bearings for the revolving rings or chucks H H attached rigidly to the bed-plates B. As shown in the dranings, these bearings are made in halves, and bolted together, forming a recess, in which the revolving rings H are securely held against lateral displacement, while they are permitted to freely revolve. One of these rings, on its inner surface, is provided with points or dogs, which engage with the stave-.cylinder when the latter is adjusted therein, and insures its rotation with the ring. The peripheries of the rings are provided with teeth h h, with which a pinion, t', is made to'engage when the ring and stave-cylinder are required to be rotated. j is the shaft upon which the pinion i is mounted. The outer end of this shaft, provided with a driving-pulley, jl, revolves in abearing, jg, attached to the bed-plate, while theinner end is mounted in an arm or lever, Z, pivoted at its upper end to the bearing D, so that the made to approach, or recede from, the revolving ring H. The bearing D is provided with a recess, 7c, and slot 7.x', to allow of this movement of the pinion t' and shaft j, respectively.

Z1 is an arm,.secured to the inner bearing O of the mandrel. The lower ends ofthe arms l Z1 are provided with a series of holes, and connected by a link, l2. m is a screw-shaft, working through a threaded lug, b2, depending from the under side of the bed-plate B. fm1 is a bevelpinion at the end of the screw-shaft, engaging' with a similar pinion, m2, on a shaft, m3, extending transversely of the frame, and rotated by a crank, m4, on the outer end thereof, by which the bed-plates and parts attached thereto are adjusted longitudinally. N N are cmrved inclines or guides, supported by standards or braces secured to the bearings D. o are levers, jointed at their lower ends to` the bed-plates B, and connected, by a link or arm, o', to' one of the tie-rods f, which connect the bearings C. P is a spring-catch, secured at one end to the bed-plate, and extending across the machine, with it-s free end provided with notches 1 p2, which alternately engage with the tie-rod j, as the bearings C are adjusted, and hold them in place, as will presently be explained.

lnstead of lthe spring-catch P, a cord and weight may be used to hold the parts in place after they l1. vc been adjusted by the levers o.

The barrel or Cask being set up, and forming a stave-cylinder, is placed with its ends resting upon the curved in clines N, when, by turning the crank m4, the rings or chucks H are made to approach each other, the inclines operating to guide the ends of the stave-cylinder into the rings or chucks H. The levers o are now moved outward, which slides the bearpinion t' can be ings C in the Ways b, so as to bring the cutters howeled, crozed, and chamfered as the cylinder 4 slowly revolves. To insure an equal depth of croze in irregular staves, a roller is put on the end of the mandrel that holds the cutters. After the stave-cylinder has completed arevolution, the levers o are pressed inward, Which withdraws the cutters from contact with the staves, and disengages the pinion i from the ring H, the inner notch, p1, of the spring-catch now engaging with the rod f, and holding the parts in place. The chucks are then Withdrawn from each other by reversing the crank m4, when the dressed cylinder of staves is removed and another cylinder substituted.

That is claimed as thc invention of the said HENRY WILBE is y 1.1In a barrel crozing and chamfering machine, the combination, With the revolving ring or chuck H, Which receives and holds the stavecylinder, of a driving-Wheel engaging With the periphery of the revolving ring, and imparting motion thereto for rotating the stave-cylinder, all constructed and arranged substantially as hereinbefore set forth.

2. The combination., with the revolving ring or chuck and dri\"ing-wheel, of the bearingI), surrounding and protecting the same from chips and dirt, substantially as hereinbefore set forth.

3. The combination, with the revolving rings H, of the relatively stationary guides N, for facilitating the chucking of the stave-cylinder, substantially as hereinbefore set forth.

4. The combination, in a barrel crozing and chamfering machine, with the longitudinallyadjustable bed-plate and bearing for the revolving ring or chuck secured thereto, of the bearings C C of the shaft of the cutter-head, made transversely adjustable on said bed-plate, substantially as hereinbefore set forth.

5. The combination, With the revolving rin or chuck which holds the stavecylinder, of the driving-Wheel and adjustable bearing for the shaft of the latter, by which said driving- Wheel is thrown in and ont of gear simultaneously With movement of the cutter-bearings, substantially as hercinbefore set forth.

6. rIhe combination, with bed-plate B, revolving ring H, andbearin gs C D, of the driving Wheel and shaft i j, arms l l1, and connect ing-link l2, by which the Wheel t' is adjusted simultaneously With the cutter-head, substantially as hereinbefore set forth.

7. The combination, with the bed-plate B and bearings C C, of the cutter-shaft, the lever o, link o', and spring-catch l), substantiallyhcreinbetore set forth.
