BOTTLE CLOSURE.

Specification of Letters Patent.

Patented May 2,

Application filed October 25, 1921. .Serial No. 510,238.

1 0 all 20 721cm it may concern Be it known that I, JOHN W. DUDLEY, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Bottle Closure, of which the following is a full, clear, and exact description.

This invention relates to bottle closures and has for an object to provide an improved construction wherein the closure may be readily applied and removed without injury to itself or to the bottle.

A further object of the invention is to provide a bottle closure having retaining spring hook members and a locking ring adapted to lock the hook members against accidental disengagement.

A still further object of the invention is to provide a closure for bottles which may be used many times and which is provided with a preliminary locking member andv an auxiliary locking or clamping member to insure a tight fitting of the closure.

In the accompanying drawing Figure 1 is a side view of the upper end of a bottle with a closure embodying the invention applied thereto.

Figure 2 is a sectional view through Figure 3 approximately on line 2-42,- part of the bottle being shown in elevation.

Figure 3 is a top plan view of the struc ture shown in Figure 1.

Figure 4 is a sectional view through Figure 1 approximately on line 44.

Figure 5 is a view similar to Figure 2 but showing the parts before the auxiliary clamping member has been operated.

Referring to the accompanying drawing by numerals, 1 indicates the neck of a bottle which is provided with a bead 2 at the upper end thus forming a groove 3 adapted to receive the lugs or hook members 4 on the spring arms 5. In the showing, three arms 5 have been illustrated but a greater number may be provided if desired. The spring arms 5 are also provided with pressed out lugs 6 and 7 acting as limiting members or stops for the retaining ring 8 which is slidingly mounted on the arms 5.

The arms 5 are preferably made integral plate 12 acting on the packing 11.

- gagement with the lugs 7 and when in this position, may be readily applied as shown in Figure 5 or removed. In case it should be desired to lock the closure in place, ring 8 is moved downwardly from the position shown in Figure 5 to that shown in Figure 2. The auxiliary clamp or screw 14 is then turned until the packing member 11 is compressed as indicated in Figure 2. This effectively closes the bottle and the structure is such that any pressure generated in the bottle will not force the closure from its position as the hook members or lugs 4 cannot move radially in view of the position of the ring 8. 7

When it is desired to remove the closure, clamping member 14 is moved in a reverse direction for releasing the cork 11 and then ring 8 is moved upwardly, whereupon the arm 5 will resiliently spring outwardly a short distance and permit the closure to be bodily removed without injuring either the closure or the bottle.

This application and removal may be made an indefinite number of times so that the stopper may be used continuously or intermittently and whenever desired without the use of tools either in applying or removing.

What I claim is A closure for bottles, comprising a clamp ing plate having a rough central portion, a packing member carried by said clamping plate on one surface thereof, an outer plate having a threaded aperture, a screw threaded into said threaded aperture and bearing against said raised portion for pressing the clamping plate and packing downwardly, said outer plate being provided with a plurality of long fingers anal a plurality of short fingers spaced between the longer ers, said short fingers acting to center saicl clamping plate said long fingers having an outwardly pressed projection for each enel and an inwardly extending projection near the outer end adapted "so interlock with a bottle, and a ring surrounding said long fingers and movable parallel to the axis of the clamping screw for causing the inwardly extending projection on said long fingers to interlock with the bottle when ihe ring is in one position and to permit said projection to move away from the bottle when the ring is in another position JQHN W. DUDLEY.
