To on whom it may concern.-

Be it known that I, HENRY P. ROBERTS, of Boston, in the county of Sufiolk, State of Massachusetts, have invented certain new and useful Improvements in Self-Sealing Bottles, of which the following isa description sufficiently full, clear, and exact to'enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being bad to the accompanying drawings, forming part of-this specification, in which Figure 1 is a sectional View of the neck or mouth of a bottle provided with my improved device, which is shown in elevation; Fig. 2 a verticaltransverse section of the same; Fig. 3 a like view showing the position of the parts when the bottle is inverted; Fig. 4 a vertical section showing details of construction; and Fig. 5 an elevation of the inner tube containing the valve-seat.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to a device for preventing the refilling of bottles after they have once been emptied without so destroying either the neck or the sealing device that it will be readily discovered by the purchaser.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation: I

In the drawings, A represents the bottleneck which at its mouth is swiveled forming an annular groove, 19.

A metallic cylinder, B, preferably constructed of aluminum is flanged at, d, (see Fig. 4) and has a cap-piece, f, overlapping its opposite end, said cap and flange forming an annular groove, h, which holds a ring, 2' of cork. The cap-piece, f, has a mouthflj'df'l ess diameter than the cylinder. Within the cylinder, B, a supplemental cylinder, 0, is inserted. Said cylinder, G, has a bead, k, which engages and rests on alip, m, reamed inward from the cylinder, B. One end, 1), of the cylinder, C, is closed. Said cylinder is greater in diameter than the. mouth, 9, of the main cylinder or body, B, which prevents the inner 5o cylinder from being withdrawn through said mouth. The opposite end of the inner cylinder, 0, is-open forming a valve-seat, 0*, which a ball-valve, 15, engages. The side walls of the cylinder, 0, are provided with ports, 0.

In constructing the device the valve-cylinder, 0, is dropped into the cylinder, B, and rests as shown, with its head engaging the shoulder, m. The mouth of the outer cylinder is then reamed inward preventing the in- 6c ner cylinder from being withdrawn. The

cork, 'i, is soaked so that it will swell and is forced into the annular groove, Z), in the bottle neck, holding the parts securely in said neck and preventing their withdrawal as it is practically impossible to insert an implement in the mouth, g, and grasp any portion of the device with sufficient force to withdraw it without destroying some parts thereof.

This groove, 1), may be located at any distance from the mouth of the bottle. v

In the use of my improvement, when the bottle is in its normal vertical position, the seat, 1", is closed by the ball-valve preventing the insertion of liquor into the bottle. soon as the bottle is inverted the ball falls away from the seat against the top, 19, of the cylinder, C, so that the liquid in the bottle may pass through the ports, 'v, in the direction indicated by arrows in Fig. 3.

Having thus explained my invention,what I claim is- 1. The combination with the outer cylinder having a mouth in'its outer end and means for securing it in the bottle neck, of the inner cylinder having its outer end closed; an open valve-seat in its lower end and ports in its side wall; a ball-valve in said inner cylinder and devices for preventing the withdrawal of said cylinder, all being arranged to operate 0 substantially as set forth.

2. The combination with the bottle, A, provided with the groove, 1), of a metallic cylinder, having an open outer end a flexible projection thereon adapted to enter said groove and secure the cylinder therein, an inner cylinder secured in said first cylinder and proclosed end, 19, ports, '1), and valve-seat, r, and vided with ports and a, valve-seat andaballthe ball-valve, t, engaging said seat all be- 10 valve for closing said seat. 1 f ing arranged to operate substantially as de- 3. The combination with the bottle,A5 ha .y scribed.
