SAFETY BOTTLE STOPPER.
APPLICATION man NOV. 10. 1921.
Patented May 16-, 1922'.

SAFETY BOTTLE STOPPER.
To all whom it may concern: "Be it known that I, JAcK F URMAN, citizen of the United States, residing at Fort Bliss, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Safety Bottle Stoppers, of which the following is a specification.
My invention relates to a safety stopper for bottles and the main object of the invention is to provide an air-tight closure which may be applied to bottles withnecks of different size.
Another object of the invention is to make the stopper safe, so that a child would be unable to remove it or open the bottle to pour out its contents.
A third object is to manufacture the stopper of inexpensive material and of such simple construction that it may loe sold cheaply and have a very wide use.
In the accompanying drawing, in which one embodiment of the invention is illustrated:
Figure l is a fragmentary elevation of a bottle with the contrivance in position and shown in vertical section,
Figure 2 shows in perspective view the details of the device, and
Figure 3 shows a modification of a detail, also in perspective view.
In the drawing, the numeral 10 represents an ordinary bottle with a neck 11 to which the stopper is applied.
The device consists of an inverted truncated cone 12, preferably made of wood and provided with a central sleeve 13 securely fastened therein. This cone 12 mayalso be made of metal but, for the sake of lightness, wood is preferable.
The sleeve 18 is threaded internally, as at 14, at its lower end, in order to engage with the threaded portion of a central post 15. This post has a knurled head 16 at its upper end and a series of spaced recesses, preferably in the form of annular grooves'17 or holes 27, a short distance below the head, or spaced holes 27 through the shank.
At its lower end the post '15 carries a mushroom-shaped disc 18 which may be threaded and pinned to the post. Between this disc and the upper cone 12 is inserted, and surrounding the post, another cone frustum 19 with its base downward and formed with thin walls 20 so as to provide a deep recess in which the mushroom-shaped disc 18 is made to enter and engage the Specification of Letters Patent. Patented May 16, 1922, Application filed November 10, 1921. Serial N0.-514,308.
walls 20 internally] The cone 19' is made of some flexible material such as rubber or the like. i
I also provide a securing nut 21 for preventing the lower cone 19 from slipping too v far down on the post'15 when the disc18 is lowered into the bottle.
At the upper end 0f the cone 12, I provide a' plunger 22 seated in'a chamber 23 in the cone and held in position by means of a plate 24 secured on the outer surface of the cone. The plunger has an exterior head 25 and a coil spring 26 is wound around its stem, abuttingat one end against the plate 24 and at the other end against a pin 26 inserted transversely near the end of theplunger.
The relative sizes of the cones are such that the upper cone 12 will rest upon the rim of the neck of the bottle without slipping down too far, while the base of the lower or rubber cone 19 is small enough to easily slip down into the neck of the bottle. When in this position, the post 15 is moved upward by turning the knurled head 16, I
when the threaded engagement between the post and the sleeve 13 will cause the disc 18 to rise and extend the side walls 20 of the lower cone soas to engage tightly in the neck of the bottle. As soon as the post has been drawn out far enough, the plunger will enter the corresponding hole-27 or groove 17 therein and prevent it from slipping down.
The spring on the plunger is made fairly strong so that it will be impossible for a small child to draw it out and remove the stopper from the bottle, thereby preventing him from pouring out its contents, which might be poisonous or in other ways injurious to him. i
Having thus described the invention, what is claimed as new is: i
1. A stoppercomprising a central post, a pair of cone-shaped members mounted on said post with their bases away from each other and axially movable thereon, one of said members having thin side walls of flexible material, a head on said post engaginginternally with said walls, and anelement for locking the parts in axial direction.
2. A stopper comprising a central post, a
pair of cone-shaped members mounted on said post with their bases away from each other, one of said members having thin side walls of flexible material, a head on said post engaging internally with said walls,
other, one of said members having thin side walls of flexible material, a head on saidpost engaging internally with said Walls, said post and the second of said members bein provided ith inter-engaging threads,
and anelem'en't for locking the parts in axial direction. v y
