To all whom t may concern:

Be it known that I, PETER E. MALMsTRoM, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvenient in Siphon-Bottles, of which the following is a specification.

The object of my inventionis to provide a siphon bottle with a metal exterior, or casing, and a glass interior, or lining, suitably supported in said casing and separated therefrom suiiiciently to leave an air chamber and also to provide suitable vents between the interior and the exterior of said lining, which will permit gas to flow, but not liquid. These and other objects are ac` complislied by my invention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which,

Figure 1 is a side elevation of my improvement. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1, looking in the direction of the arrows. Fig. 3 is a plan View of a washer. Fig. 4 is an enlarged sectional view taken on the line 4 4 of Fig. 3, looking in the direction of the arrows.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My improved bottle 1 consists of an exterior casing 2, a glass or similar lining 3, a spring 4 placed on the bottom of said casing and on which said lining rests, a siphon head 5 supporting a siphon tube 6 in the conventional manner, and other parts, as will appear below.

The casing 2 may be of any suitable outline, but is preferably made, as shown, with a cylindrical body 7, closed at its lower end and surrounded by a cap 8 at its upper end. The cap 8 and bottom 7 are secured together by solder or other suitable material. The upper end of the cap 8 forms a neck 9, which is provided with screw threads and to this is secured a siphon head of the conventional form and in the manner sh'own. The tube 6 is provided with a flange 10 at its upper end, which rests on a packing 11 and forces the same in contact with the top of the neck 9.

On the interior of the cap 8 and at the base of the neck 9 is a coiled spring 12, which presses against a seat 13, of the usual form, and this seat 13 rests on a disk 14 of rubber, or similar material, which is placed on a flanged disk 15, the flanges running both ways, the upper flange surrounding the disk 14, and the lower flange surrounding the top of the lining 3, as shown in Fig. 2. The disk 14 is provided with two slots 16 and 17 respectively, each of which is provided with an enlarged opening. The opening 18 is on the upper side of the disk and forms a part of the slot 16, and the opening 19 is on the lower surface of the disk and forms a portion of the slot 17. If desired, the disk may be reversed as it can be used with either side up. It is provided with a central perforation 20 for the tube 6.

My improved siphon is used in the usual manner and charged in the conventional way. Any excess gases can escape into the space, between the lining and casing 2 through the opening 17 and there remain. When the liquid is removed from the bottle, the gases between the lining and casing return through the opening 16. Both openings 16 and 17 are normally closed because their walls are pressed together by the elasticity of the washer, but either will open at its large end 18 or 19 when a gas under pressure appears therein. Neither will open for any liquid that is not under pressure and so these openings are liquid tight for all practical purposes.

l/Vhile I have shown and described one embodiment of my invention, it is obvious that it is not resctricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims.

What I claim is:

1. In a device of the class described, a fluid tight outer casing having a siphon head, a manually controlled. valve normally closing the siphon head, a gaseous fluid container within said casing of less capacity than the latter to provide a space between the same, said container having an inlet vent, means closing one end of the container and having normally closed vents to permit escape of gas from the latter into said space, and a tube leading from the siphon head through said means into the container.

2. In a device of the classdescribed, a casing, a gaseous Huid receiver of less capacity than the casing disposed therein to provide a space therebetween, said container having an inlet vent, siphon mechanism carried by the casing and communicating with the re ceiver, and means on the receiver to permit the escape of gas from the same into the said space.

3. In a device oit' the class described, a casing, a gaseous Huid receiver of less capacity than the casing disposed therein to provide a space therebetween, said container having an inlet vent, siphon mechanism carried by the casing and communicating with the receiver, means on the receiver to permit the escape of gas from the same into the said space, and a spring holding the said means in position on the receiver.

l-. In a device of the class described, a casing, a receiver Within the same of less capacity than the latter, an elastic disk mounted upon the receiver and having normally closed inlet and outlet vents, whereby gas free of liquid may escape from the receiver into the casing and means holding the disk in position upon the receiver.

'In a device of the class described, an outer casing, an inner casing arranged within the latter to provide a space therebetween, said inner easing having an inlet vent, spring means between opposite ends of said inner and outer casings, and means on the inner casing for permitting` gas free of liquid to escape from the latter into said space.

G. In a device of the class described, inner and outer casings, the inner casing being of less size than the outer casing, there being an inlet vent for the inner casing and an outlet vent, and means holding the inner casing firmly Within the outer casing.

7. ln a device of the class described, outer and inner casings, the inner casing being of less size than the outer casing, there being an inlet vent for the inner casing, means holding the inner casing firmly Within the outer casing, and means permitting excess gas pressure to discharge from the inner casing into the outer casing.

8. in a device of the class described, outer and inner casings, the inner casing being of less size than the outer casing, there being a normally .closed inlet vent for said inner casing, means holding the inner casing firmly Within the outer casing, means permitting excess gas pressure to discharge from the inner casing into the outer casing, and siphon mechanism communicating with the inner casing.

Signed at the city of New York. countv of New York and State of New York, this 27th day of January, 1910.
