VlVlACHI'NE FOR CUTTING TAPERED CORKS.v

SPECIFICATION forming part of Letters Patent No. 242,304, dated May 31, 1881.

Application filed March 12, 1881.

To all whom it may concern:

Be it known that I, GEORGE WASHINGTON GREENE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Machines for Outtin g Tapered Gorks and Bungs, of which the following is a specification.

Figure l is a sectional side elevation of my improvement. Fig. 2 is a perspective view ot' the mandrel, cutter-holder, and sliding` collar.

Fig. 3 is a front elevation of the same, and showing the device for applying a power-feed. Fig. 11 is a front view of the same, and showing a hand-feed. Fig. 5 is a perspective view of a saw-edged cutter. Fig. Gis a perspective view ot' a knife-edged cutter. Fig. 7 represents a modification of the cutter-mandrel.

Similar letters of reference indicate corresponding parts.

The object of this invention is to facilitate the cutting of tapered corks and bun gs.

A represents the table that supports the machine, and to which is attached a frame, pedestal, or bracket, B.

In bearings C, attached to the frame B, revolves a shaft, D, to which is attached a pulley, E, to receive the driving-belt. One or both ends of the shaft D project and have screw-threads cut upon them to fit into screwholes in the base ofthe mandrel F. The mandrel F is tapered, and to it is secured, by screws G or other suitable means, the cutter-holder H, which is made in one, two, or more parts, accordin g as one, two, or more cutters are to be used. The inner surface ot` the cutter-holder H is so formed as to tit upon the tapered mandrel F, and its outer surface is cylindrical. The adjacent edges of the parts of the cutterholder Hare rabbeted, forming T-grooves I to receive the cutters J, the blades of which are made with serrated edges, as shown in Fig. 5, or with smooth edges, as shown in Fig. 6, accordin g as the character of the material to be operated upon may require. The Shanks or bodies of the cutters J are formed to tit into the T-grooves I, and upon the outer sides of the said shanks are formed arms K, which project beyond the outer surface of the cutterholder H to enter a ring-groove, L, in the inner surface of the collar M, so that the cutters J can be moved out and in by sliding the said (No model.)

collar M forward and back upon the said cutter-holder H.

Upon the opposite sides of the collar M are formed gudgeons N, to receive the yoke O, to which the power is applied to slide the cutters J forward and back. When the collar M is to be moved forward and back by power, the yoke O is made in the forni of a half-ring with bearings in its ends to receive the gudgeons N, and with a right-angled arm, P, upon its middle part. Upon the end of the arm l? is formed a screw-thread to fit into the screw-thread in one end of the long nut Q. The nut Q, has a right serewthread in one end and a left screwthread in the other end, and into the screwthread iu its other end fits a screw-thread formed upon the end ofa bar, R, which slides in bearings S attached to Jthe frame B. When two mandrels, F, and their attachments are connected with the shaft D, the oppositeends of the sliding bar R are connected with the yokes 0 of the two collars M, so that the cutters J of the one mandrel F will be pushed forward as the cutters J of the other mandrel F are drawn back. When two mandrels are used they may be so made that the machine will cut corks or bungs of the same size or of different sizes, as may be desired. With this construction, by turning the right-and-left nuts Q, the cutters J may be projected to a greater orless distance as the desired length of the corks or bun gs may require.

To the center ofthe sliding bar R is pivoted the upper end of the lever T, which is pivoted to a suitable support, U, attached to the table A. The lower end of the lever T is designed to be inserted in a cam-groove in a cylinder placed beneath the table A, and revolved by a belt from the driving-power, so that the knives can be projected and retracted automatically.

The cam-grooved cylinder is not shown in the drawings, as there is nothing new in its construction.

The yoke 0 may be made in the form of a ring, as shown in Fig. 4, and when the cutters are to be fed forward and back by hand the said yoke has stems V XV formed upon it at right angles with and equally distant from the bearings for the gudgeons N.

In the stem V is formed a bearing parallel IOO with the bearings for the gudgeons N to rcceive a pivoting-screw, X, which is screwed into the top ot' a pedestal, post, or other support, Y. In the stem YV is secured a lever or handle, Z, by means of which the operator moves the knives J forward and back.

In a pedestal, a, placed in front of the mandrel F, is formed an openingin which is placed a block, b, of hard woodfor the cork, wood, or other material to rest against while being operated upon by the cutters J, so that the edges of the said cutters will not be dulled. The block b is secured in place detachably by a setscrew, c, passing in through the top of the pedestal af, and resting against or entering the said block b.

To the block b or to the pedestal a is pivoted a roller, d, for the material to rest upon while being cut, so that it can be readily adjusted. The mandrel I" can be arranged with its smaller end forward, as shown in Fig. l, so as to cut the larger ends of the corlrs or bun gs rst; or the said mandrel can be arranged with its larger end forward, as shown in Fig. 7, so as to cut the smaller ends ot' the corls or bungs rst.

Having thus fully described my invention, claim as new and desire to secure by Letters Patentl. In a machine for cutting tapered corks and bungs, the combination, with the shaft D, of the tapered mandrel F, the cylindrical cutter-holder H, made to fit the mandrel F, and having T-grooves I, the cutters J, having outwardly-projecting arms K, the sliding collar M, having interior groove L and gudgeons N, and the yoke Q,for moving the cutters forward and back, substantially as herein shown and described.

2. In a machine for cutting tapered corks and bungs, the combination, with the yoke O, hung from the sliding collar M, that moves the cutters J, ot' the screw-arm I), the right-andleft nut Q, the sliding bar R, and the pivoted lever T, substantially as herein shown and described, whercby the critters can be fed forward and back by vibrating the said lever, as set forth.
