JOHN HOWE, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO I-IIMSELF AND ONE- I-IALF TO JAMES BLUMER, 0F NEW YORK, N. Y.

CORK AND BUNG CUTTER.

Application filed July 15, 1909. Serial No. 507,689.

Specification of Letters Patent.

Patented Sept. 6, 1910.

To all whom it may concern:

Be it known that I, JOHN Hown, a citizen of the United States, residing in East New York, in the county of Kings, city and State of New York, have invented an Improvement in Cork and Bung Cutters, of which the following is a specification. j

Heretofore in the manufacture of corks and bungs for bottles, casks and similar liquid-holding vessels it has been usual to cut the same from the cork sheets with parallel sides and of true cylindrical form and then either again cut the corks or the bungs tapering in another and special inachine, or compress the cylindrical cork at one end prior to forcing the same into the neck of the bottle or other vessel. Corks and bungs for bottles, casks and similar liquid-holding vessels have also been cut tapering out of the cork sliding cutters.

The object of my invention is the provision of a revoluble cutter of special construction which shall at one operation cut a cork tapering in form ready for use without further treatment.

In carrying out my invention, I provide a built-up revoluble head in part. hollow7 and tapering, means forrevolving the head, a series of knives or cutters circularly arranged and means for slidably reciprocating the same axially of the head and other means for simultaneously guiding the knives or cutters over the surface of the tapering head. A surrounding tapering sleeve encom asses the knives or cutters and serves to holt them in position. The place where the cutters protrude on the end of the head represents the maximum diameter of the cork or bung being cut, and vas the knives emerge they approach, contracting the diameter.

The device of my invention is to be made in various sizes according to the sizes of the tapering' corks or bungs to be cut.

In the drawing, Figure l is a plan and section through the sleeve representing the device of my improvement; the cutters being in their retracted position. Fig. 2 is a similar plan and section with the cutters projecting. Fig. 3 is a longitudinal section also showing the devices for reciprocating sheets by suitable the cutters. Fig. 4 is a cross section at the dotted line 0c, fr, of Fig. 2. Fig. 5 is a cross section at the dotted line y, y, of Fig. 3, and Fig. 6 is an illustrative section showing the relation of the cutters as projected and in the act of cutting a cork from a strip against a foundation. The section Fig. 3 is taken approximately on the dotted line a, a, of Fig. 5

a represent-s the head stock. This is recessed at one end to receive the tubular spindle b, which in turn is connected to a suitable revoluble foundation not shown, for the purpose of turning the entire cutting implement. The head stock a is reduced and exteriorly threaded and recessed and interiorly threaded at the opposite end.

I provide a tapering head c exteriorly threaded at its larger end and screwing into the recessed portion of the head stock and within the larger end of the tapering head c a stop ring d is received and held. The tapering head is provided with spaced longitudinal slots 2, and e represents a tapering sleeve interiorly threaded at its larger end and screwing upon the reduced exteriorly threaded end of the head stock. Between the tapering head c and tapering sleeve e is an annular recess receiving the series of knives or cutters f. These are of slightly curved cross section arranged slightly spaced apart in the retracted condition in Figs. l and 3, and adapted when projected as in Fig. 2, to come together along their edges. The knives or cutters f of the series are each provided with a slot 3 receiving the head of a stud 4L, the shank of which is secured in the tapering head cy and these cutters are each perforated fora bolt 5. These bolts 5 are of peculiar construction as will appear particularly from Figs. 3 and 5. Each one has a threaded portion which passes through the opening in the cutter and a nut 6 coming against the outer surface of the cutter, and two shouldered portions; one shouldered portion coming against the under surface of the cutter in the slot 2 of the tapering head c in which this portion of the bolt is parallel sided. The lower portion of the bolt is oppositely spread and shouldered as seen in Fig. 5 so that the lower shoulders come at opposite sides beneath the inner surface of the tapering head c; therefore while the bolts 5 forni guides in the slots Q for the cutters f, outward movement of said bolts is prevented by the shoulders which come against the inner surface of the head 0.

Fig. 5 indicates that the several bolts or series are disposed radially with referencek to the axial center of the cutting device.

I provide a rod t in the axial center of the cutting device with a head h1, and a sleeve z' surrounding the rod fitting the apertured center of the head stock and the open center of the tubular spindle b and guided therein and this sleeve is provided with a head il. This rod 7L and sleeve are connected in a deinite relation by a pin 7 so as to provide Jfor the spacing apart of the head h1 from the head l and also providing for these heads coming at opposite sides of the bolts 5. The rod L and the sleeve t consequently move together and are actuated by a lever 7c manually operated, or by an equivalent device which is adapted to impart reciprocating movements to the rod h, sleeve z' and their heads and in turn to actuate and reciprocate the series of cutters from the retracted positions ot Figs. l and 3 to the extended or projected relation shown in Fig. 4, and between which positions with the rapid rotation ot' the head stock and connected parts, the cutters have passed through the slab or sheet of cork and cut therefrom a cork or bung of tapering form.

This device is preferably made in various sizes according to the size ot' the cork or bung which is to be formed, the same operating with one action and stroke in forming a cork or bung of tapering character.

I claim as my invention:

l. The combination with a revoluble head stock, of a hollow tapering head connected therewith and longitudinally slotted, a series of knives or cutters circularly arranged upon the surface of the hollow tapering head, means connected to said cutters and passing through the slots of the hollow head, and other means connected with the latter means providing for a reciprocation of said cutters simultaneously with their revolution by the revoluble head stock.

2. The combination with a revoluble head stock, of a hollow tapering head connected therewith and longitudinally slotted, a series of knives or cutters circularly ar y'anged upon the surface of the hollow tapering head, means connected to said cutters and passing` through the slots of the hollow head, other means connected with the latter means providing for a reciprocation ot' said cutters simultaneously with their revolution by the revoluble head stock, and an imperforate surrounding tapering sleeve inclosing the series of knives or cutters.

3. A cork or bung cutter, Comprising a head stock, a tubular spindle adapted to be revolved, a tapering head connected to the head stock and provided with spaced apart longitudinal slots, a series of knives or cutters circularly arranged around the tapering head and also provided with spaced slots, studs secured in the tapering head and having parts received in the slots of the cutters, and bolts passing through the slots of the tapering head and connected to the series of knives or cutters, and means adapted for longitudinal movement and for engagement with said bolts for reciprocating the said series of knives or cutters.

a. A cork or bung cutter, comprising a head stock, a tubular spindle adapted to be revolved, a tapering head connected to the head stock and provided with spaced apart longitudinal slots, a series of knives or cutters circularly arranged around the tapering head and also provided with spaced slots, st-uds secured in the tapering head and having parts received in the slots of the cutters, and bolts passing through the slots of the tapering head and connected to the series of knives or cutters, an axially disposed rod and a surrounding sleeve connected together, and means for moving the same through the center of the head stock and tubular spindle, a head Jformed with said rod and another head formed with said sleeve and spaced apart to come at opposite sides of said bolts, whereby a reciprocating movement is imparted to the series of knives or cutters.
