Description

-UNITED STATES PATENT OFFICE.

JOHN BUCKINGHAM AND JOSEPH H. BARD, OF WATERTOVN, CONNEDTICUT,

' ASSIGNORS TO THE SCOVILLEMANUFAOTURING COMPANY.

IMPRovl-:D MILLING-Tool..

T0 all whom t may concern.-

Be it known that we, JOHN BUCKINGHAM and JosEPHH. BAIRD, of Watertown, in the county of Litchfield and State of Connecticut, have invented a new and usefu'limprovement in the apparatus bywhich a rotary die is ernployed to impress ornamental or other figures upon metal or other substances; and I do hereby declare that the following is a full and exact description of the said improvement.

The rotary die as heretofore employed has been capable of following such path only upon the surface to be impressed as it may follow Without change in the position and direction `of the axis about which itrotates.

The purpose of our improvement is to cause the rotary die to follow such paths upon the surface to be impressed as demand a vibratory motion in the axis ofthe rotary die.

Ourimprovement consists in placing the cheeks which hold the axle of' the rotary die A upon another axle, which is at right angles to the axis of rotation and not in the same plane, as is hereinafter more fully described, reference being had to the drawings annexed, and the letters ot' reference marked thereon, making part of this specification.

Drawing No. 1 represents in perspective the tool which is used, Drawing No. 2 represents the handle or holder into which it is to be fitted, and which forms a part of the tool. Drawing No. 3 is a sectional View of the tool and handle properly fitted to each other.

In Drawing No. l, a represents an axle, to which is firmly attached a head-piece l), or

both can be made in one piece.

c represents another piece of metalfastened to the-head-piece b by means of the screw e, which Works through a lslot cut in c.

d is the rotary die, its axle being at right angles with the axle d, and placed out of the line of the axle a to any desired extent by means of the slot in c and the screw g.

In order to apply this tool to the use for lwhich it is designed, (as running ornamental knurls, beading, or borders or other figures on picture-frames, daguerreotype-mattings, metal boxes, cases, &c.,) We place it in the handle or holderrepresented byDrawingNo.`2,the end t of the axle a, entering the eye or hole j,

and another portion of it near the head-piece` resting in the bearing 7a and being kept in place by the shoulder Z, the axle a, with the parts attached to it, being free to move on its own axis. Then fasten the handle or holder into a rest of the kind ordinarily attached to a lathe for turning metals, and, having fastened the metal or other substance upon which the figure is to be impressed into the lathe,

bring up the rest in such a manner that the axis ot' the rotary dieWill be parallel to the surface of the metal to be impressed and its periphery in contact therewith. The metal upon which the ligure is to beimpressed may then be made to revolve with a curvilinearv motion by any known method, as in a circle on a common lathe, or in an ellipse or oval by means of a lathe fitted with eccentric machinery for that purpose, in either case the axle a, being free to turn on its own axis and thev center of the die d being out of the line of the axle a, it permits the die to follow the windings of a c urve by a lateral vibratory or alternating motion. When the path Which the die is to follow isnot sufficiently determined by the motion of the surface on which the impression is to be `made `or by its form,

'a slight preliminary tracing will be sufcient JoHN EUCKINGHAM. JOSEPH H. BAIRD.
