CORK-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent NO. 295,884, dated March 25, 1 884:.

' Application filed March 29,1883. (No model.)

To all whom it may concern/.-

Be it known that I, FREDERICK J. NUTTING, of the city of Brooklyn, in the county of Kings and State of New York, have. made. certain new and useful Improvements in Cork-Outting Machines; and I hereby declare that the following is a fulland clear description of the same, reference being bad to the accompanying drawings, in which- Figure 1 is a side elevation of my cork-cutting device. Fig. 2 is a top view of the same. Fig. 3 is a view of the guide-wheel for the driving-belt. Fig. 4: is a View of the end of the pulley-wheel P, showing the stop-clutch. Figs. 5', 6, 7, and 8 are views of the device for holding the cork-Wood;-and Fig. 9 is a sectional view, showing the central. rod for eX- pelling the cork from the cutter.

, The object of my invention is to provide a machine for cutting corks from cork-Wood with a revolving cylindrical knife working at an incline and across the length of the bench on which it is placed, while at the same time the cork-wood is always automatically held firmly in position when the knife enters it, and the motion or thrust of the cutting-knife may be governed and regulated by the foot of the operator.

1 In the drawings,A represents the bed-plate or base upon which the cutting machinery rests, orto which it is secured. This bed-plate or base is firmly secured to a bench or table, B, by suitable supports, and arranged so that it will be at right angles to and across the length of the bench and at an incline with the plane of the bench, as shown in the drawings, Fig. 1.

Secured to the bed-plate A are standards Q O, which serve as supports and guides for a knife-holding cylinder, D, which is revolved by a belt, E, passing around a driving-pulley, G, on a revolving shaft, T, and the pulley H on the cylinder D.

The cylindrical cutting-knife I is secured to the cylinder D, and in front of it is arranged the mechanismfor holding the strip of corkwood during the operation of cutting the cork. The knife carrying cylinder D is hollow throughout, and has secured to it at one end the cylindrical knife or cutter I, and at the other end has secured to it the two collars O O. Projecting from the standard C, in a line with and below the knife-carrying cylinder D,

-is rod or pin, J, sliding on which is a yoke,

tion a, secured to and revolving with a shaft, Q, and the part d, which is loose and revolves freely on the shaft Q. The shaft Q is connected at one end to the crank-shaft M by a universal joint, R, as shown in Fig. 2, and is provided with suitable bearings, m and n.

S is a belt running over the pulley P and a pulley-wheel, U, on the revolving shaft T.

The shaft Q has its bearings m and n so arranged that it is set at an angle to the drivingshaft T and the crank-shaft M. This is done in order to bring the face of the cone-shaped por' tion of the pulley-wheel P about parallel with the shaft T and the face of its pulley-wheel U,

although I have found in practice that it is best and in front of the pulley P, is a guide, W,

arranged to carry the sliding wheel Y, through which.the belt S runs onto the pulley-wheel I. The position of the wheel Y is regulated by the treadle or foot-lever Z, to which the wheel Y is connected by the cord X. The position and arrangement of the pulley P and belt S is such that the normal position of the belt is on the loose portion (1 of the pulley P, which draws upon the cord X and raises the treadle Z. On the end of the pulley P is secured a clutch or projection, 0, which is reenforced by a spring,p, and sliding on the guide W is a projecting arm, a, in position to engage the catch 0 when the belt is running on the loose wheel (I, and instantly stop the revolutions of the shaft Q and the crankM,

operation of cutting.

so that the knife I will be stationary in a pothe shaft of the companion pulley, nor aconesition where it is withdrawn from the corkwood. g

In front of the cutting-knife I is arranged a cutting-block, V, faced with lead or box-wood in the usual manner, and provided with an adjustable rest, r, for the strip of cork-wood s to restupon.

Secured to the base-plate A in front of the cutting-block is an adjustable slotted arm, H,

and passing through it is a pin, 1;, to which the holders h h are secured. These holders h h each have a wing, t', set at an angle, as shown in Fig. 8, and are connected together by abar, w, about the base of the wings t z.

W is a rod passing loosely through the stand ards O and O, and extending far enough back of the standard 0 to receive pressure from the yoke N at every forward thrust of the knife-cylinder. The rod WV is provided at its forward end with a catch-arm, a, which catches on the bar 10, so as to keep the holders h h up in position against the corkwood during the The arm 2 is arranged to slide on the end of the rod W, as shown in Fig. 5, being pivoted on a sliding block, y, resting on a spiral spring, as, which is designed to take up any excess of pressure from the in Fig. 9 with the cylindrical holder and knife in section. a

In the operation of my improved machine, the length of the knife being across the bench and on an incline instead of on alevel with it, the operator has a better control over its operation, so that the work is greatly facilitated. In cutting corks a strip of cork-wood is placed in position 011 the adjustable rest r, and the holders h h are brought up against it, sufficient pressure only being applied to keep the holders in an upright position and permit the strip of cork to be freely moved. When all is ready for cutting, the foot of the operator is pressed upon the treadle Z, which will bring the belt S onto the conical pulley c and cause the cutting-knife I to be worked at arate of speed which is governed by the pressure on the foot-lever or treadle Z, while both hands of the operator are at liberty to manipulate the cork-wood in front of the knife. The holders h h are pressed firmly against the cork-wood each time the cuttingknife enters it, and the pressure is relieved when the knife is withdrawn, so that the strip may be readily shifted and an uncut portion brought in front of the knife. The wings i t are arranged to effectually shield the hands of the operator from any accidental contact with the cutting-knife. I do not herein claim, broadly, a cone-pulley the axis of which is at an angle to the axis of pulley so arranged, in combination with a universal joint and a crank, as I hereby reserve the right to obtain a separate patent or patents for such subject-matter when considered apart from the particular machine herein de scribed.

\Vhat I claim 'as my invention, and desire to secure by Letters 'Patent, is-

1. The combination, substantially as described, of a bench, a knife-cylinder arranged transversely to said bench and at an incline thereto, provided with a cylindrical knife, and means for imparting rotary and reciprocatory motion to said cylinder.

2. The combination, substantially as de-' scribed, of a reciprocatory rotary knife-cylinder provided with a cylindrical knife, a cylindrical drivingpulley, a cone-pulley the shaft of which is at an angle to the shaft of the driving-pulley, whereby the outer or belt-bearing face of the cone-pulley is parallel with the face of the cylindrical pulley, a belt stretched between said pulleys, and' mechanism between the shaft of said cone-pulley and said cylinder for converting the rotary motion of the former into the reciprocatory rotary motion of the latter.

3. The combination, substantially as described. of a reciprocatory knife-cylinder, a crank-shaft at a right angle thereto, means for connecting the crank of-said shaft with said cylinder, a shaft arranged at an obtuse angle to said crank-shaft, a universal joint connecting said shafts, and a cone-pulley on said inclined shaft, the belt-bearing face of which is parallel, or nearly so, with the face of the driving-pulley.

t. The combination, substantially as set forth, of a reciprocatory knife-cylinder, a

crank shaft at an angle thereto, means for connecting the crank of said shaft with said cyland means for connecting said belt-shifter F. J. N'UTTING.
