XVILLIAM J. STOOP, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO M. G. LESLIE AND HUGH FURGESON, OF SAME PLACE.

CORK-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 464,593, dated December 8, 1891.

' Application led December 4. 1890- Serial No. 373,600. (No model.)

To all whom it may concern.-

Be it known that LVVILLIAM J. STOOP, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Cork-Cutting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improved corkcutting machine; and it consists in certain details of construction and combination of parts, as will be fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a sectional plan View of my improved machine. Fig. 2 is a side elevation of the same. Fig. 3 is a face view of the knife-box. Fig. 4 is a side elevation of the same. Fig. 5 is a sectional end elevation of the adjustable cutterblock. Fig. 6 is a face view of the clamp.

To construct a machine for cutting corks of various sizes, I provide a base-plate a, of suitable size and form of construction, and secure SVO thereto two bearings b, in which is journ'aled a stout hollow shaft c, having a flange dformed on one end of the same, to which a cutter-box e is bolted. This shaftc is operated by abeltwheel f and is adapted to be revolved at avery high speed. Operating within the cutter-box e, which consists in an open-ended rectangular casting, is an oblong` interiorly-arranged box g, which maybe arranged atan angle with the outer box e, and set or secured by means of screws h passing through slots formed in the top and bottom of the cutter-box e. Secured within this inner box gis a rectangular casting i, capable of being moved in the direction of its length by means of a rod jlpassing through the hollow shaft o and pivotally connected at one end and attached to a handlever k by a ball-joint Z. Secured within this sliding piece z', which is kept in position and the wear of the same taken up by suitable gibs m, is a circular plug n, confined by a screw o, which holds a knife or cutter p securely therein, Arrangedat the front of this be formed.

knife p is a wooden block q, which is held by a bolt to a small frame r, capable of being adj Listed toward or away from the knife and held in any desired position by set-screws passing through flanges formed on the bed-plate. At- 5 5 tached to the hand-leverc by means of a sliding connection s is a rod t, which moves parallel in bearings w w and is provided at its forward end with a semicircular clamp u for holding the cork-wood while being cut. Ar- 6o ranged at the front of the block q and attached to the frame r is an adjustable guide x, which may be elevated or lowered when making sev eral sizes .of corks. Beneath the hand-lever k is a bar y', having two collars e' capable of 65 being adjusted and set at anyposition along the bar y', and thereby regulating the stroke of the lever 7c.

By reference toFigs. 3 and 4 of the drawings it will be seen that the box or casting e, 7o which rotates with the shaft c, carries with it the adjustable knife-box g, which, as has been explained, can be inclined or tilted-at an angle to the longitudinal axis of the shaft c, and as the knife p within the box partakes of its angular or inclined adjustment it follows that the knife is adjusted at an angle to the axis of the, shaft, whereby the knife can be made to cut inclined surfaces on corks which are circular in cross-section. 8o

In operation this machine may be used for cutting various sizes of tapering corks. The wood is first cut into strips having a width equal to the greatest diameter of the cork to The machine is put in motion, 8 5 and by means of the lever 7c the knife p drawn back, having firstadjusted the box g in an inclined position to make the knife corre. spond t-o the size and taper of the cork to be formed. These cork-wood strips are held 9o against the end of the wooden block q and supported by the guide and the hand-lever 7c moved to the left, which moves the clamp u against the wood, together with the knife p, which, being in an inclined or angular position and having a rapid circular motion, cuts or shears a tapering cork from the wood. The pressure is removed from the handle k and the same forced back to its original position by means of a spiral spring operating roo against a fixed collar and the bearing zi' of the rod. It will be seen by reference to the drawings, Figs. 3 and 1, that the knife may be adjusted to ent a cork of large or small diameter and at the same time form any taper.

I-Iaving thus described my invention, I claim l. In a corleutting machine, the combination, Wit-h a rotary hollow shaft, ot` a knifebox fitted therein and ad j nstable at an angle to the axis of said shaft, means for holding said knife-box Within the shaft, a longitudinally-movable carrier fi, fitted Within the knife-box, and the knife tted to said carrier, substantially as described.

2. In a cork-cutting machine, the eombination, with a rotary hollovsT shaft, of an adjustable polygonal knife-box fitted therein, a polygonal knife-carrier fitted snugly Within said knife-box, a knife fixed to said carrier, a lever, and a pitman connected to the knife carrier and having 'a ball-and-soeket connection with the lever, substantially as described.

3. In a cork-cutting machine, the combination, with a hollow rotary shaft, of the slotted polygonal box or casting carried by said shaft, the k nite-box fitted snugly in said box or casting and fixed therein by screws working in the slots of the box or casting, a sliding knifecarrier keyed in the knife-box and having the knife fixed thereto, the lever, and the pitnian extending through the hollow shaft and having one end connected by a ball-and-socket joint with the lever, substantially as described.

In testimony that I claim the foregoing I hereunto affix my signature this 12th day of November, A. I). 1390.

W'ILIAIAM J. STOOP.
