UNITED STATES PATENT (NEIGE.`

lMPROVEMENT IN CORK-CUTTING MACHINES.

- Specilicatiou forming part of Letters Patent No, 35,867, datcd July 15, 1862.

To all whom it may concern,.-

Beit known thatl, HAEETs BOARDMAN, of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Improvementin CoileCutting Machines; and I do hereby declare that the following is a full, clear, and exact descrip/tion ofthe construction and operation of the same, reference being had to the annexed drawings, making a part ot' this specilication,in which*- Figure l is a perspective view of the cylindrical cutterwith its scalloped or lance point edges; Fig. 2, a portion of the same laid open; Fig. 3, a'view in perspective of the whole machine.

I employ a cylindrical cutter, Fig. l, constructed by forming the cutting-edge so as to constitute a series of lance-blade points instead of a smooth continuous cylindrical edge for cutting` cork, in orderto prevent the heating and loss of temper in the thin steel cylindrical cutter, thereby also doing away with the necessity of employing a rimmer or crown` saw. Such a series of points or blades are also better 'adapted for overcoming the elasticity and spriuginess of the cork, and prevent its binding effect upon the tool.

To operate this cutter I employ an upright stand, F, having a table, T, on which the slab ofV cork is laid. The toolestock, with its long traverse pulley I? and bearings b, is made tubular, into which the rod R, adjusted by asetscrew, S, on the top of the standard F, enters, this rod being fixed or stationary when adjusted, and expelling` the cut cork as the tool is raised up for another cut. The tool hold ing the cutter-pulley and bearings is aftixed by brackets B B to a plate, D, sliding up and down in side grooves on the upright standard F, and is drawn up by means of a treadle or lever, L, having a chain or rope overapulley, Q, attached thereto. There is also an ad j ustable stop, E, which arrests the sliding plate, gaged so that the cutter simply penetrates through the cork or slab. The tool is revolved by means of a strap traversing over the long pulley P in the up-and-down motions of the tool, the tool descending by its own gravity or the action ofthe lever, which may he em-` ployed in either direction by means of or without a pending weight.

Iam aware that movable rods are used in a horizontal position for a similar object. I am also aware that cutters or tools are employed in a vertical position; nor do I claim such. Neither do I claim a cylindrical cutter, as such with a smooth cutting-edge has been used, as well as split cylindrical cutters, for cutting corks tapering. I therefore do not claim a cylindrical cutter operated vertically, as those referred to.

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

The combined arrangement of the cutter, as described, sliding tool-stock operated by a treadle, adjustable stop E, long traverse pulley P, and adjustable stationary rod R, substantially as and for the purposes herein specitied.

HARRIS BOARDMAN.
