SPRINKLNG BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent N o. 716,806, dated December 23, 1902.

Application iled September 23, 1902. Serial No. 124,551. (No model.)

To all whom t may concern.:

Be it known that I, HARRY O. BRAWNER, a citizen of the United States, and a resident ot Baltimore, State of Maryland, have invented certain new and useful Improvements in Sprinkling Bottle-Stoppers, of which the following is a specication.

My invention relates to sprinkling bottlestoppers adapted to permit the discharge of liquid contents from bottles by drops when the bottle is held in inverted position and agitated, and more particularly to such Stoppers as that described and claimed in my Patent No. 646,349, dated March 27, 1900. In the manufacture and use of the parts comprising Stoppers of the character covered by my said patent it sometimes happens that corks of larger sizes than intended for the bottle-mouth are selected, in which case the perforation in the cork when inserted in such bottle-mouth is so decreased in size by compression that the Walls of the said perforation sometimes bind the enlarged head of the valve, thus causing the latter to stick, preventing its free movement when the bottle is agitated, there by diminishing or stopping the dropping ot' the liquid contents of the .bottle and with a head of hemispherical contour. The perforation or opening in which the shank or stem plays is contracted to an equal extent on all sides, thus closing the opening below the head, because of the contact of the wall of said opening with the under side of the head and with the side of the shank or stem.

The object of my present invention is to provide a means whereby this objection may be entirely obviated, thereby rendering the operation of the sprinkler more perfect and certain and at the same time making it unnecessary to use much care-in the selection of the Stoppers for a particular size of bottle, thus conducing to economy of time in the assembling ot" the device upon the bottles.

With this object in view my invention consists in the novel construction of sprinklingstopper and the details thereof, as hereinafter described with reference to the accompanying drawings and more particularly pointed out in the claims hereto appended.

In the drawings, Figure l is a sectional view of a bottle-neck, showing my present invention applied to a bottle. Fig. 2 is a transverse section on the line 2 2, Fig. 1. Fig. 3 is a similar View showing the parts When the cork iscompressed. Fig. 4 is a similar View showing the position of parts with thecork compressed when the head of the stopper is hemispherical, and Fig. 5 is a detail view of a modification.

As in my prior patented construction, the

mouth of the bottle 1 is fitted with a cork 2, through which extends a central perforation or opening 3, closed by a glass stopper 2a and contractedlin size a short distance from the bottom, forming a shoulder or seat 4. The bottle stopper consists of a simple shank or stem 8, passing through the contracted oriiice 3fl and provided with enlarged heads 6 and 7 at each end. The upper head 6l overlaps the opening y3a and engages the shoulder surrounding the orifice and. being capable of a to-and-fro movement Within the cork-body when the bottle is agitated. The lower head 7 of the said stopper is adapted to seat against the lower end of the cork and cover the opening therein to seal the contents oi the bottle against discharge when the bot* tle is inverted, and the shank 8 is of slightlyless diameter than the opening in the cork through which the stem or shank passes, whereby a dropping-orifice is provided between the shank and the side Wall of the contracted orifice.

Instead of making the upper enlarged head 6 of the stopper hemispherical or other shape designed to fully and completely seal the perforation in the lower end of the cork, in my present improvement I so construct this head as to provide a free passage for the liquid contents of the bottle, even when the cork is inserted in a mouth which is smaller than intended for the particular size of cork, so that when the cork is subjected to compression in such a mouth the side walls of the opening will not bind the head 6 of the stopper 5 to such an extent as to cut od the dropping-orice, as shown in Fig. 4, by reference to which it will be seen that when the cork is compressed sufticiently'to bring the Walls of the perforation in contact with IOO the head 6 and the shank the passage for cork will as it is compressed be received at separated points of contact, whereby the contour of the dropping-orifice will be elongated or distorted in such a manner as to preserve a passage or conduit for the escape of liquid from the bottle when the latter is inverted and agitated.

In Figs. l and 2 I have shown the preferred form of my improved stopper, wherein the head 6 is flat or elongated, the ends extending over and overlapping the opening and adapted to be engaged by the walls of the perforation 3 above the contracted opening 3L when the cork is compressed under the conditions hereinbefore specified.

As the cork is compressed the walls of the perforation 3 come into contact with the ends of the elongated head 6, and thereby prevent the contracted opening 3a from closing in on all sides of the stem or shank 8, the said contracted opening being elongated or distorted, assuming the shape shown in Fig. 3, where the sides of the said contracted opening are shown in contact with the stem at separated points of contact, but slightly expanded at points at right angles to the line joining the the points of contact of the head 6 with the side walls of the perforation 3. With an elongated head 6 the general contour of the distorted opening 3 is that of an ellipse with its major axis at right angles to the larger axis of the head 6 or to a line joining the points of contact of the head and cork, thereby preserving a free passage between the stem or shank and the cork to permit the dropping of the liquid therethrough when the bottle is inverted and agitated.

Other forms of the head 6 may be used to accomplish the result desired, though the one just described is preferred. For eXample, the head may be shaped as shown in Fig. 5, where the head 61L is provided with grooves or recesses 9 on one or more sides, which give to the head such a contour as will insure the separated points of contact between the cork and the head when said cork is compressed. Other forms of head may be used to the same end, the essential thing being to provide a head which shall receive at certain points the pressure of the sides of the cork in such a manner as tocause the side of the cork body forming the Wall of the opening'through which the stem of the stopper passes to be distorted so as to recede from the side of the stem a sufficient distance to prevent complete closing of the wall of the opening around the stem, and thus provide a passage or orifice for the dropping liquid.

I claim as my inventionl. Abottle stopper and sprinkler consisting of a cork having formed therein an opening, and a stopper comprising a simple stem occupying said opening and being of sufficiently less diameter than said opening to provide a dropping-orifice, the said stem having enlarged heads overlapping the opening and the head within the opening constructed to receive pressure of the cork body at separated points of contact when the cork is compressed and thereby prevent the opening from being compressed into close contact with the stem, substantially as described.

2. A sprinkling bottle-stopper consisting of a cork having formed therethrough an opening contracted at its lower end and forming a shoulder within the opening and surrounding the said contracted end, and a stopper comprising a simple stem of suffiently less diameter than the contracted opening to provide a dropping-orifice, the said st em having enlarged heads overlapping the contracted opening, the head within the opening being elongated, whereby its ends are adapted to receive the pressure of the cork body when the latter is compressed by insertion in a bottle-mouth and the droppingorifice distorted so as to prevent the closing thereof by contact with the stem, substantially as described.

3. A sprinkling bottle-stopper comprising a perforated cork adapted to be seated in a bottle-mouth, having an internal shoulder at its lower end, a contracted orifice in the lowerend of the cork communicating with the perforation thereof, a stopper consisting of a simple stem of slightly less diameter than the orifice having enlarged heads overlapping the orifice on opposite sides thereof, the head within the perforation of the cork being normally out of contact with the wallof the perforation in the cork but constructed to receive the pressure of said wall at separated points of contact and thereby cause the oriiice to be distorted when the cork is cornpressed around the stopper, substantially as described.

4. The combination with a perforated compressible cork seated in a bottle-mouth, of a stopper operating in the lower end of said perforation and adapted to provide a dropping-orifice for the liquid contents of the bottle when the latter is inverted and agitated, and provided with means within the perforation of the cork for preventing the cork from being compressed upon the said stopper to such an extent as to close the dropping-orifice, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
