EDWARD CONROY, OF SOUTH BOSTON, MASSACHUSETTS.

CORK-MACHIN E.

Specification of Letters Patent No. 17,557, dated June 16, 1857.

To all whom it may concern:

Be it known that I, EDWARD Connor, of South Boston, in the county of Suffolk and State of Massachusetts, have invented a. new and Improved Implement or Device for Cutting Corks or Bungs; and I do hereby.

declare that the following is a full, clear. and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a vertical section of my improvement; the plane of section passing through the center. Fig. 2, is an inverted plan or face view of the cutting device. Fig. 3, is a horizontal section of ditto; (m), (00), Fig. 1, showing the plane of section.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improved construction of cutter head in which expanding cutters are used and operated in a simple or novel manner by the stuff as it is fed to the cutters. The cutters, in consequence of their gradual expansion, cutting the corks or bungs from the stuff in conical form, with the greatest facility and with a small expenditure of power.

The invention also relates to the means employed for feeding the stuff to the cutter head, when said means are used in connection with the cutter head, as will be herein after described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents a rectangular framing which may be constructed in any proper manner to support the working parts.

B, represents the driving or power shaft which is placed on the upper part of the framing A; and C, is a shaft placed in the lower part of the framing and driven from the shaft B, by a belt D. On the shaft C, a bevel pinion E, is placed, and this pinion E, gears into a wheel F, which is placed. on the inner end of a shaft G, which is placed longitudinally within the framing A, and

somewhat inclined. On the outer end of the shaft C, a screw H, is placed, and this screw gears into a main wheel I, on a shaft J, which is parallel with the shafts B, C. At each end of the shaft J, an eccentric or cam K, is placed, and on these eccentrics or cams a horizontal bed L, rests, said bed having a pendent at each end, the pendent fitting in grooves in the framing and serving as guides for the bed.

M, represents a vertical arbor which is fitted in suitable bearings at one end of the framing A, directly over the bed L, at about its center. The arbor M, is driven by a belt (1)), from the driving or power shaft B.

N, is a rod which is fitted vertically in the lower part of the arbor M, and has a pin (a), passing transversely through its upper part; said pin working in slots (J), in the sides of the arbor and serving as a guide for the rod N, (see Fig. A spiral spring (0), is fitted within the arborM, and bears against its upper end. A collar 0, is placed on the arbor M, and is connected to the rod N, by a pin (f), which passes transversely through the rod and also through the slots (cl), in the sides of the arbor M.

P, P, representrods at the lower ends of which cutters (f) are attached or formed. The upper ends of the rods P, have pins (9), passing transversely through them, a pin passing through each rod, and these pins are fitted in recesses (71), atopposite sides of the arbor M. To opposite sides of the collar O, springs Q, are attached, and the lower ends of these springs bear or rest against the rods P.

R, represents a plate, the sides of which are inclined or beveled. This plate passes through the rod N, and the sides of the plate R, bear against the inner sides of the rods P, as shown clearly in Fig. 1.

Itwill be understood that the pins (9), of the rods P, are allowed to work laterally in the recesses (h). The lower end of the arbor M, has a flanch 0 around it; said flanch having slots (2'), made through it, through which the rods P pass.

To each end of the bed L, a spiral spring S is attached.

The operation is as follows: The stuff shown by dotted lines from which the corks or bungs are cut, is placed on the bed L, and motion is given the power shaft B, in any proper manner. The arbor M, is rotated by the belt (1)), and the bed L, is moved up ward, and the stuff consequently fed to the cutters (f (f by the cams K. The stuff bears against thelower end of the rod N, and

horizontally or nearly so, as the pins (9),

are allowed to move laterally in their re cesses (h) the cutters (f (f owing to their rotating motion and their lateral movement, cut the corks or bungs in conical form, the sides of the corks or bungs beingiperfectly straight and not of curved or concave form. l/Vhen the prominent portions of the cams have'passed the bed L, the bed is depressed or brought back to its original position by the springs S. The cams, of

course, are so formed that they will feed the 7 stuff upward the requisite height in order that the cutters will cut through the stuff.

I do not claim the employment or use of expanding cutters, for cutting corks, bungs, etc, irrespective of the arrangement herein shown, for-expanding cutters have been pre- Viously used, although differently arranged from the plan herein shown; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is: I

1. The expanding cutters attached to the rods or bars P, and operated by the plate R, attached to the rod N; the rods P, having pins (9), passing through their upper ends, which pins are allowed to slide laterally in their recesses (h), as the rods are actuated by the plate R, the above parts being arranged substantially as herein described, for the purpose set forth.

I further claim, in "combination with the cutters (7) arranged and operated as shown, the cams K, and bed L, for feeding the stuff to the cutters.

EDWVARD CONROY.
