JOSEPH B. BURROW, OF JOHN, WASHINGTON.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 587,790, dated August 10, 1897.

Application filed October 7,1896.

To aZZ whom it may concern:

Be it known that I, JOSEPH B. BURROW, a citizen of the United States, residing at St; John, in the county of Whitman and State of Washington, have invented certain new and useful Improvements in Bottle-Stoppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in stoppers for bottles, the object of the same being to provide a stopper which may be readily inserted into the neck of a bottle of ordinary construction, but which when it has been once inserted cannot be drawn outwardly for the purpose ofclosing the neck of the bottle, thereby producing a non-refillable bottle.

The invention consists of a stopper to be used in connection with bottles having a square shoulder between the main body and neck-of the bottle, made up of a cork of ordinary construction a wire shank projecting centrally through said cork and extending outwardly from the upper end thereof, a spring secured to the lower projecting end of said shank and extending outwardly beyond the edges of said cork, a cross-arm upon the upper end of {said shank, and outwardlyspring pressed arms having flanges upon their lower ends, which are adapted to engage the shoulder of said bottle when the cork is forced inwardly for the purpose of removing the contents of the bottle.

The invention also consists in other. details of construction and combinations of parts which will be more fully described and claimed hereinafter.

In the drawings forming a part of this specification, Figure 1 represents a view of a bottle with my improved stopper applied. Fig. 2 is a similar view of the same with the stopper forced inwardly to the position it assumes when the contents of the bottle are to be removed. Fig. 3 is' a detail perspective view of the stopper.

Like reference-numerals indicate like parts in the different views.

The bottle 1 is of ordinary form of construction and has a contracted neck 2 upon its upper end, with a shoulder 3 formed between the body portion of the bottle and said neck.

My improved stopper is made up of a cork 4, adapted to fit within the neck 2 and having a wire shank 5 projecting through the center of said cork and extending outwardly from the upper end thereof. The lower end of said shank has a loop 6 formed in it, in which is inserted a spring 7 in the form of a ring with two outwardly-extending arms 8 8, which project beyond the outer edge of the cork 4. The upper end of the shank 5 has a cross-ar1n 9 formed upon it, to which are secured two spring-arms 1O 10, with outwardlyextending flanges 11 11 upon their lower ends, as clearly shown. The tendency of the springarms 10 10 is to spring outwardly.

In applying my improved stopper to a bot-.

tle the same is grasped by the cross-arm 9 and the cork 4 forced through the opening in the neck 2 of the bottle, slightly bending inwardly the arms 8 8 of the spring 7 so that they may pass through the openingin said neck. When the shoulder 3 of the bottle has been reached, the arms 8 spring outwardly, bearing against the underside of said shoulder. It is then impossible to draw the cork 4 outwardly, as its movement is prevented by the engagement of the spring-arms 8 with said shoulder. It should be stated in this connection that the said spring-arms, by reason of their peculiar construction, are adapted to bend upwardly but not downwardly. In order to remove the contents of the bottle, therefore, it is necessary to force the cork 4 inwardly beyond the shoulder 3, which is done by continuing the downward movement of thecross-arm 9.

When the flanges 11 on the spring-arms 1O lower end of said shank projecting outwardly beyondtheedgencfi said cork, andspring-arms on theupper end of said shank havingflanges upon their lower ends which are adapted to 5 engage the shoulder beneath the neck of the bottle, when the said stopper is forced inwardly.
