Application filed January 27, 1920. 1 Serial No. 354,377

To all whom it concern:

Be it known that 1, ROBERT S'rooK, a

citizen of the United States, and resident of the city. of Sandusky, in the county of Erie and State of Ohio, have invented a new and useful Improvement in Bottle-Caps, of which the following is a specification.

This invention relates to improvements in bottle caps and has for its object to provide a detachable closure for bottles, which is simple in construction and inexpensive to manufacture; which will efficiently seal the neck of a bottle when applied thereto, and which may be applied to and removed from the bottle innumerably without destroying its usefulness.

A practical embodiment of my invention is represented in the accompanying drawing, in which, 1

Figure 1 represents 'a plan view of my improved cap applied to a bottle.

Fig. 2 represents a similar view with the parts in the position they assume when the cap is placed on the bottle prior to being clamped or removed.

Fig. 3 represents a side elevation of the cap in the position shown in Fig. 1 and a dotted outline showing the position the operating means assumes when the cap is being removed.

Fig. 4 represents a vertical section taken in the plane of the line IVIV of Fig. 1, looking in the direction of the arrows, and Fig. 5 represents a vertical section taken in the plane of the line V-V of Fig. 1, looking in the direction of the arrows.

The bottle, to which my improved cap is applied, is provided with an annular bead denoted by 1, formed at the mouth of the bottle, and an annular recess 2, on the neck 3 of the bottle immediately below the bead.

The cap 4 is formed with a depending flange 5 which has a series of fingers 6 arranged to be bent to receive and retain in position thereon a resilient ring 7. This ring 7 is developed into a loop having converging sides 8--9 connected by a side 10. The sides 8 and 9 are flattened, as shown at ll, and arranged to cross one over the other, so that the loop will extend outwardly in the same horizontal plane as the ring and fingers. A plate 12 is hinged to swing on the side 10 toward and away from the loop, and provided with a V shaped member 13, which projects outwardly from the plate and adapted to enter the loop and engage the sides 8+9 to spread them apart. The plate isalso provided with cars 14: arranged to engage the sides 8 and 9 to limit thedownward movement of the plate and V shaped member, and also to serve as a means for manipulating the plate.

The ring 7 is normally expanded to hold the fingers a slight distance away from the recess 2, when the cap is placed in position on the bottle prior to being clamped thereon,

so that as the sides 8 and 9are forced apart by the plate 12 and member 13, the ring will be contracted and the fingers pressed inwardly intothe recess. The interior diameter of the ring and fingers is approximately less than the exterior diameter of the bead 1 on the neck of the bottle, so that as the cap is forced downward or removed from the neck, the ring will be expanded beyond its normal condition and will return to its normal condition after passing over or from the bead.

A tight closure is effected between the mouth of the bottle and the cap by means of a disk shaped washer 15 of cork or other yielding material which will be pressed tightly over the mouth of the bottle by the contraction of the ring and fingers engaging the lower edge of the bead, as shown in Figs. 8 and4.

To provide for the unintentional displacement .of the plate and member when the cap is clamped in position on the bottle, the member 13 is provided with notches 16 which hook under the sides 8--9 as shown in Fig. 5. The cap may be movedfrom the bottle my swinging the plate and member to the position shown in Fig. 2 and in dotted outline in Fi 3, which'movement will first force the Salts 89 apart to release them from the notches and the further movement will allow the ring 7 to expand and draw the fingers away from the walls. of the recess 2. A slight upward pressure on the cap will cause the ring and fingers to engage the bead and be expanded a sufficient distance to pass the bead. The loop may also serve as a convenient means by which the cap may be lifted from the bottle.

It is obvious that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence' I do not intend to be limited to the details herein shown and described, eXcept as they may be included in the claims.

\Vhat I claim is:

1.' A bottle cap having depending fingers, a ring carried by said fingers developed into a loop extending laterally therefrom, and means adaptedto swing toward and away from'said loop for actuating said ring and fingers. V

2. A'bottle cap having depending fingers, a ring carried by said fingers developed into a loop extending laterally therefrom, and meanshinged on said loop adapted to swing into the loop for contracting said ring and fingers. 1' 3. A bottle cap having depending fingers,

va ring carried by said fingers developed into a loop extending laterally therefrom, means hinged on said loop adapted to swing toward and away from the loop, and

a device on said means for entering the loop to contract said ring and fingers.

4. A bottle cap having depending fingers, 2

a ring carried by said fingers twisted and developed into a loop extending laterally therefrom, and means hinged on said loop and adapted to swing into the loop for contracting said ring and fingers.

5. A bottle cap ring developed into a loop extending laterally therefrom, and means hinged on said loop adapted to swing into said loop for contracting said ring.

6. A bottle cap ring twisted and developed into a loop extending laterally therefrom and means hinged on said loop adapted to swing into the loop for contracting said ring.

In testimony, that I claim the foregoing as my invention, I have signed my nann this 23rd day of January 1920.

ROBERT STOCK.
