Letters Patent No. 98,666, dated January 11, 1,870.

IMPROVEMENT IN MACHINERY FOR IUTTING- BARREL-HEADS.

The Schedule referred to in these Letters Patent and makingvparb of the same.

To all whom 'it may concern.:

Be it known `that I, PHILANDER CHASE, of the city and countyof Peoria, and State of Illinois, have invented a new and improved Machine for Cutting Disks, Barrel-Heads, dto.; auddo hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings,

making a part ot' this speciticatiomin which like let-v ters of reference refer to like parts, and in which- Figure l represents a perspective view.

Figures 2 and 3'are vertical sections.

This machine is for turning small wooden disks for spring-bed bottoms, pail and tub-bottoms, heads for barrelsfand kegs of all sizes, bungs, and circular pie-` ture-frames, and allother similar work requiring the aid of v,the stationary Inandrel to secure the board while it is being cut.

It eonsists of a revolving mandrel, C, with a hollow 'shank rotating round a stationarymandi-cl, D, which steadies and holds the disk or other article to be turned, in such` a manner, while it is being severed from the board, as to prevent it from being moved or` shifted, the rotating mandrel being driven by a i belt, and having a circular head, d, on the end thereof, provided with suitable knives and cbisels, so arranged as'to divide the disk or head from the board in "any number of heads of different sizes and shapes to be attached and driven bythe Sallie mandrel, the head y being fastened by a screw and key, orthe mandrel and head may be cast solid for. one `kind oi work.

lhe lower part of the mandrel is provided with a collar, W, in the bore, which colla-r is to` steady the stationary mandrel.

A pulley, r, is cast with the mandrel, to receive a band for running the machine.

The mandrel D is supported, when not at work, by a. spiral spring, S, surrounding it, between the upper journal-box z and a pin `passed through next to the end of the mandrela In a working machine, the rotating mandrel will lbe raised by a weighaf, seen in fig. 1 of the drawings, which will be made to balance and raise it to a nicet-y.

`An arm, l, passes through and works in a slot in the standard A, which arm embraces wthe stationary Amandrel D, and is connected by a Vrod with the lever` Of, which isheldby the uprightrack 11 behind the i standard. Thus the lever can bc. vinadc to hold the mandrel-head and teeth n-tight down on the wo'od to be cut. e

The lever an, on the top of the stanllurih'has an arm descending in front. of the machine,- to the topof the The lower face ot the stationary matnlrcl-head u may be of any `size that .will rest-inside ci the diameteroccupied'by the chisels and-plane-bit. 1t' to hold a single piec'e,it need not be large, but it designed` to hold a Vtub`bottom or barrel -head to be cut out of several pieces, it must be large enough to hold them tov theirplaces, and have a row of small teeth near the um. l,

The chiselsor cutters-'used' in thislngnnha'flfhead are shown in lig. 3. l

The chisel g, for dividing the disk or` head from thc boa-rd l1 b, consists of two separate parallel knives pro- ]'ccting vertically downwardii'om the lower end ol' chisel, one cutting-edge being placed in the rear of the other, and. making together a cut ot about vone-eighth to one-fourth of an inch apart. vThis makes the lirst out, and isfiinmediately followed by the plow-chisel 7l, e

seen` behind the former chisel at` It.. lig. 3, but is broader in a large-r machine,which chisel, la, cleans out the groove cnt by the chisel just described.

The chisel g is also represented as having a wider spread between its two cutters thanlin a large machine.

The chisel f makes the circular out for the edge of the chisel e or-planebit, to work up to and prevent a ragged edge bei-ng made ou the disk.

g These chisels may beset in the head in theordinary manner.

The cutting-edges of the chisel g must not be placed side by side, but one in the rear, or in advance of the other, as otherwise they will get clogged with chips.

The operatiouof this machine is as follows:

lhe wood or board `ii'oni whicl-l'the disk or pail-head is to bc cut, is laid 'ou the bed B, beneath the mandrels. Lhe leverrO-is then forced down until the stationary mandrel D holds the board rigidly on the bed, when the lever is then caught in the teeth of the rack p. The rotating mandrel, being putin motion, is

held up by the weight at z until it is ready for use, when the foot is placed on the trcadle t, and by depressing it, the cutter (l is brought to the surface of the wood, and the pressure continued until the turning is completed andthe disk severed from the board, when the foot is removed and theontter-head becomes elevated again, and by releasing the lever O, lche stationary mandrel is thrown up bythe spring S, and the disk removed to give room for n similar operation.I

Hin-viner thus fully described my invention, 'What I claim therein as new, and desire to secure `lby Letters Patent, is@ v l'. The combination of the `plane-bit e, cutters f and g, and plow-bit, with the rotating cutter-bead l1, constructed substantially in the ma-nner'and 'for the pruDQSes as herein set forth. i

2.' The arrangement of lche cutter-head d, oonstruetds described, with the arm i, lever m, weight fc, rod n, treadleerm k,- couneeting-rod, lever 0, and rack p, all constructed and operating substantially in the manner and for the purposes as herevnset forth.

In testimony that I claim lthe foregoing as my in-y vention, I have hereunto set my hand, this 23d day of March, 1869. i
