DEVICE FOR REMOVING INTERNAL BOTTLE-CAPS- SPEQIFICATION forming part of Letters Patent No. 784,851, dated March 14, 1905.

Application filed July 25, 1904. Serial No. 218,062.

To all whom itjmcty concern:

Be it known that I, FREDERICK M. GLAEs- SEL, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Devices for Removing Internal Bottle-Caps, of which the following is a specification, reference being had to the accompanying drawings.

My invention is for a new and improved device for removinginternal caps from bottles, and particularly that class of caps or stoppers which are in general well known to the trade under the name of aluminium stoppers and are particularly used for stoppers for beer and malt beverages in general. This well-known aluminium stopper consists of a cup-like device in form adapted to fit within the neck of cumferential groove of such a character that when the cap is forced into the bottle the rubber band is held between the groove in the bottle and the groove in the cap, the rubber being pressed so that the cap is held very tightly in the bottle, so as to resist pressure'from the gas in the contained liquid. As the cap is thus constructed, this forming of the circumferential recess on its outer surface causes a corresponding circumferential ridge on the inside of the sides of the cap.

It is the object of my invention to provide a device which may be readily, surely, and quickly operated to remove a stopper of this character from a bottle, together with the rubber ring which surrounds it,without injuring the stopper, and particularly to improve upon the device-for removing such internalcaps shown and described in an application filed by me in the Patent ()ffice of the United States on the 24th day of November, 1903, Serial No. 182,563. 1

In the accompanying drawings, Figure 1 is a longitudinal section through my device and part of the bottle neck and cap, showing one of the deeper forms of cap. Fig. 2 is a similar section to that shown in Fig. 1, showing, however, one of the shallower forms of cap. Fig. 3is a top or plan view of my device. Fig. 4 is a front view of my device. Fig. 5 is a detail showing the hood or guide removed from the stopper; and Fig. 6 is a detail, being an isometric view of the extractor with the hood or guide removed.

Referring to the drawings, 7 indicates a base which is provided at each end with suitable openings through which screws may be inserted to secure it to any suitable support, as the edge of the table 8. (Shown in Figs. 1 and 2.)

9 indicates an arm, which is preferably formed integral with the base 7 and projects forward therefrom. The arm 9 has a flat portion 10, which extends forward asuitabledistance to receive and support the guide, hereinafter described, and is provided with a screw-threaded opening 11. Forward of the flat surface 10 the upper portion of the stopper slopes downward. The lower edge of the arm 9 is slightly curved, as shown, and is adapted to bear upon the top of the bottleneck. The forward end of the arm 9 is cut .from below to form a beveled or angularlyface 12.

14. indicates a second engaging edge formed upon the upper surface of the arm 9 a short distance above the engaging edge 13. The engaging edges 13 14 are rounded to form a curved edge, preferably formed upon the arc of a circle to correspond with the circular shape of the inside of the cap, so as to engage the inside surface of the cap and not perforate the same, so that the cap may not be torn by the engaging of the edge or edges therewith and cut through the cap instead of removing the same.

15 indicates a hood or guide, which is pressed or molded out of any suitable material, preferably steel or similar material. The hood or guide 15 is of a general conical tion 16, extending a shortdistance therefrom and open at the end, as is best shown in Fig. 5, and adapted to closely lit over the arm 9 and rest firmly upon the flattened portion 10 of its upper surface. The hood or guide 15 is secured to the arm 9 by a screw 17, which passes through a suitable opening in the projection 16 into the screw-threaded opening 11 on the arm 9. The conical or flaring part of the hood or guide 15 is adapted when in place, as above described, to engage the upper end of the bottle-neck and guide the arm 9 into the cap in such a way that when the bottle is pressed up against it the under surface of the arm 9 will engage the top of the bottle-neck, the beveled or angularly-disposed bearingsurface 12 will engage and rest upon the inside bottom of the cap, and the engaging edges 13 1 1, or one of them, will engage the inside upright portion of the cap back of the rubber band and below the top edge of the cap. When a shallower form of cap is used, as is shown in Fig. 2, only the edge 13 engages the cap, which can be readily removed, as hereinafter described, by the single engaging edge.

, l/Vhen a deeper form of cap is used, as is shown in Fig. 1, the resistance is such that a single engaging edge will sometimes leave the rubber band behind when the cap is removed, and l have therefore formed the two engaging edges 13 1 1 as above described in order that in such a case both of these engaging edges may engage the inside of the cap below its upper edge, thus insuring its removal.

\Vhen it is desired to remove the cap from the bottle, the bottle is thrust up into the hood or guide 15, which causes the arm 9 to be guided with certainty into the proper position in the cap, as above described, and the bottle is pressed into it sui'liciently to insure this engagement. The bottle is then moved down by hand into the position shown in dotted lines in Figs. 1 and 2, thus removing the cap from the bottle.

That which 1 claim as my invention, and desire to secure by Letters Patent, is

1. In a device for removing internal bottlecaps, the combination with a flaring guide adapted to engage the top of a bottle-neck, of an arm rigid with said guide and projecting within the same, adapted to bear on its under side upon the top of a bottle-neck and provided with an engaging edge adapted to engage the inside of the cap below its edge, said flaring guide and said arm being so placed with reference to each other that when a bottle is inserted in the said guide the engaging edge of the arm engages the inside of the cap, substantially as described.

2. In a device for removinginternal bottlecaps, the combination with a partially coneshaped guide open from below and adapted to engage the top of a bottle neck and guide the same, of an arm projecting into said guide from one side and rigidly secured thereto, adapted to bear on its under side upon the top of the bottle-neck and provided at its end with an engaging edge adapted to engage the inside of the cap below the edge thereof, said guide and arm being so placed with reference to each other that when the neck of a bottle is thrust into said guide the engaging edge of said arm will engage the inside of the cap below the edge, substantially as described.

3. In a device for removing internal bottlecaps, the combination with an arm adapted to bear on its under side on the top of a bottleneck and having at its end an edge adapted to engage the inside of the cap below its edge, ofa flaring guide secured to said arm,'par tially inclosing the same and adapted to engage the top of a bottle-neck inserted in it and to guide said arm into engaging position in said cap, substantially as described.

4. A device for removing internal bottlecaps, consisting of an arm adapted to bear on its under side on the top of a bottle-neck and having at its ends an angularly-disposed or beveled bearing-surface adapted to bear upon the upper surface of the cap, the front portion of said beveled surface merginginto an edge adapted to engage the inside of the cap below the edge thereof, and a flaring guide secured to said arm, adapted to engage the top of a bottle-neck moved into it and to direct the arm into said cap With its engaging edge and bearing-surface engaging the same, substantially as described.
