RICHARD WHITAKER, JR., OF NEW BRUNSVJIK, NEW JERSEY, ASSIGNOB TO M'AIJU- FAGTULRERS IRON & STEEL COJVHEANY, OF NEW BRUNSWICK, NEW JERSEY, A COR- PORATION OF NEW JERSEY.

BOTTLE STOPPER AND METHOD OF MAKING THE SAME.

Application filed August 14, 1920.

sex and titate of New Jersey, have invented a new and useful Improvement in Bottle Stoppers and Methods of Making the Same,

of which the following is a specification.

The invention relates to bottle stoppers and method of making the same, and more particularly to bottle stoppers of the type in which a toggle joint is used in the manipulation of the stopper. 1

Bottle stoppers of the above type usually consist of a seal, composed of some resilient material such as rubber, which is used to close the mouth of the bottle, a base or body part carrying the seal, and a bail connected with the toggle and on which the body part is loosely suspended. Heretofore, so far as known, the body part of the stopper has been relatively expensive, weak, (with much consequent breakage, particularly at the point where it is connected with the bail) rough and not readily galvanized, and the part or flange for holding the seal so formed that the seal often becomes detached therefrom. It is the object of the present invention to eliminate the above enumerated disadvantages and provide an improved bottle stopper. This object is accomplished by the bottle stopper and the method of making the same hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings illustrating the completed improved bottle stopper and the various steps in the practice of the method by which it is made, Fig. 1 shows the blank; from which the body part of the stopper is formed; Figs. 2- and 3 are a side elevation and top plan respectively of the blank on the completion of the first operation; Figs. 4 and 5 are a side elevation and top plan respectively on the completion of the second operation; Figs. 6 and 7 area side elevation and top plan respectively of the body part as completed at the end of the third operation; and Fig. 8 is a side elevation of the completed stopper showing the body part attached to the bail and with the resilient seal thereon.

Serial No. 403A95.

stopper is subjected to a series of operations by which it is converted. from the blank form shown in Fig. 1 to the finished form shown in Figs. 6 and '7. This series of operations comprises the novel feature of the method part of the invention. Theblank 10 shown inFig. 1, which is a cylindrical piece of malleable metal, such as common rivet wire, is first subjected to a swaging or other operation by which the collar 11 is formed thereon and one end thereof isshaped as a truncated cone, as shown at 12 in Fig. 2 The collar 11 and truncated cone 12 are preferably formed simultaneously at one operation, although under some conditions it is best to use two operations. These parts may also be formed simultaneously with the cutting of the blank 10 to the proper length. The cone 12 is then slotted, as shown at 13 in Figs. 1 and 5 to serve as the recess in which the bail is loosely received. On the completion of the first operation, which may be performed in a horizontal machine, the blanks may fall into a hopper and be conveyed to a saw for the cutting of the slot. The slot 13 extends from the top of the cone 12 down to the collar 11 and for this reason the part 12 is made pyramidal in form in order that it may be of suflicient strength for its purpose. By providing a pyramidal or cone-shaped part for receiving the bail, it will be observed that not only is it made very strong but also a rela' tively long surface is afforded against which the bail takes. By reason of this construction the body part can only shift longitudinally on the bail. This is of advantage in inserting the seal in the mouth of the bottle. The next step in the operation is to close in the free ends of the two sides 1% and 15 of the cone 12, left by the cutting of the slot 13, and to form on the shank 16 a flange 1'? for holding the resilient seal in place. The

flange 17 may be formed in a number of 1 bler and tumbled to remove burrs, and they are then galvanized. The relatively smooth surface of the malleable metal causes it to take the galvanizing readily. The body part of the stopper is now completed and is ready for use by inserting the bail 19 of the bottle through the closed slot 13 as shown in Fig. 8, and forcing on the resilient seal 20.

The series of operations to which the cylindrical blank 10 is subjected inconvertingit into the finished body part of the bottle stopper as shown. in Figs. 6, 7 and 8 isysiinple and of such nature that the body part of the stopper may be manufactured with great rapidity and at relatively little cost. Inasmuchas the body part of the stopper is composed of a malleable metal it is necessarily much stronger than a casting and therefore can stand the stresses to which it issubjected, in use with far less liability of breaki'n than is the case when it is composed. of a casting. Moreover, the spinning or swagingof the flange 17 by which the resilient seal is held in place enables this part to be provided. With sharp corners as shown at 21 in Figs. 6 and 8. It will be recognized that it is, diflicult toprovide sharp corners on a casting of such size and form and c011- sequently, where the body part is formed from a piece of malleable metal and the flange for holding the. resilient seal is swaged orspun into shape, it is in such form as to most efficiently hold the resilient seal in place. s

near 2'25 Having thus described the invention, what is claimed is 1. The method of making the body part of a bottle stopper which comprises swaging a cylindrical piece of malleable metal to pro vide thereon a collar and a bail receiving part, slottingthe bail receiving part, closing the open end thereof and forming on the opposite end of the piece a flange for retaining the bottle seal.

2. The method of making the body part of a bottle stopper which comprises forming a cylindrical piece of malleable metal into a collar, a truncated-cone, slotting the cone, closing the open end thereot'to provide a bail receiving part and forming on the other end of the piece a flange for retaining in position the seal of the bottle. I

3. As an article of manufacture, a body part for bottle stoppers formed from a oylindrical piece of malleable metal, swaged to comprise a collar and a bail receiving part, the bail receiving part having been slot-ted to accommodate the bail and its open end closed, and savaged or spun to provide a seal retaining part.

41. As an article of manufacture, a body part. for bottle stoppers formed from a sin gle piece of malleable metal and operated upon by pressure to comprise a collar, .a bail receiving part and a seal retaining part, said bail receiving part beingprovided with an opening to receive the bail.
