MACHINE FOR CUTTING CORKS.

Specification of Letters Patent No. 20,770, dated Ju1y 6, 1858.

To all whom 'it may concern:

Be it known that I, ROBERT P. ABERNETHY, of Cincinnati, Hamilton county, Ohio, have invented new and useful Improvements in Cork-Cutting Machinery; and I hereby. declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

The rst part of my invention relates to an automatic device for feeding the blank to the mandrels.

The second part of my invention relates to an automatic device for cutting oval corks.

In the accompanying drawings Figure l is an isometric view of a machine with my improvements. Fig. 2 is an aXial section thereof at the plane :c m .c Fig. 1. Fig. 3 is a frontview of the feeding mechanism and ovaling mechanism on an enlarged scale. Figs. 4 and 5 are side views of the same in different positions.

A, is a frame supporting a horizontal cutter wheel j, armed with four knives 7c. Four counter shafts l, are so geared together as to revolve four times at each revolution of the cutter wheel.

Stationary but adjustable headstocks c, c, support mandrels r, s, one of which (r) at the proper moment for grasping the blank is slid forward in its bearings. Each pair of mandrels is so geared to a counter shaft as to commence rotating on the instant that the knife has entered the full length of the blank, and the two mandrels together make just one revolution during the remainder of the cut, when the recession of the sliding mandrel liberates the then finished cork.

Journaled horizontally to the frame (so as to move in a vertical plane) is an arm d, having a rectangularly notched head e, adapted to hold the square piece or blank, out of which a bottle cork is made. At one end of this notch is a small yielding strip of metal f, of such shape as when advanced to remain clear of the stationary mandrel. This strip f, serves as a shoulder or stop for the end of the blank, its pliability permitting a slight longitudinal movement in obedience to the sliding mandrel. A lip g which curves outward and downward from the head e, receives the finished cork from the mandrels and conducts it into the discharging spout g. An intermittent vibratory motion is given to the arm CZ, by means of a suitable cam F, which derives its motion from the same mechanism which operates t-he mandrels. The arm el, with its appendages I style the automatic feed rest d, e, f, g.

The parts are so arranged that the rest is moved up in time for the blank to be grasped by the mandrel just before the incision of the knife, when being relinquished by the cam it is retracted by spring or weight.

For making oval corks I effect a slight elevation and depression of the mandrels, twice during every rotation by means of eccentrics H, connected to the mandrel shafts by rods I. In order to admit of the desired play of the mandrels their front ends occupy vertical slots in the headstocks, which while restraining any lateral play permit a slight vertical oscillation of the mandrels. In order to effect these rela-tive motions the eccentric shafts are geared to make two revo lutions for every revolution of the mandrels. The amount of ovaling is varied at pleasure by changing the eccentricity of the eccentric sheaves, which for this purpose may consist of rings and may be made adjustable further from or nearer to concentricity with the shaft by set screws h., engaging in slotted collars k.' The rods I, are capable of being lengthened or shortened by means of screws z'. By this automatic mechanism thin slabs may be worked up into oval corks similar to those now made by hand.

The improvements may be used in conjunction with any forms of suitable intermittently acting cutters and mandrels.

I claim as new and of my invention herein:

l. In this connection, the automatic feed rest CZ, e, f, g, substantially as set forth.

2. Imparting to the mandrels of a cork cutting machine, a compound rotary and vibratory movement by means and for the purposes substantially as set forth.

In testimony of which invention I hereunto set my hand. R. P. ABERNETHY.
