SIPHON-FITTING.

SPECIFICATION forming part of Letters Patent N o. 666,214, dated January 15, 1901.

Application filed March '7, 1900. serial No. 7,751. (No model.)

To all whom it may concern.-

Be it known that we, HERMANUS VAN NIM- WEGEN, brewery manager, and JOHAN JACOB BRUNS, manufacturer, subjects of the Queen of the Netherlands, and residents of Vossenstraat 72, Arnhem, in the Kingdom of the Netherlands, have invented certain new and useful Improvements in orRelating to Siphon- Fittingsfor Aerated-Water Siphons or the Like, of which the following isaspecification.

The present invention relates to an improvement in Siphon-fittings for aerated-water siphons and the like; and it consists of the parts and combination of parts hereinafter pointed out.

In the annexed drawings this improvement is represented as follows:

Figure 1 is an elevation of the fitting; and Fig. 2 a section thereof on line I to II in Fig. 1, also showing part of the Siphon-bottle. Figs. 3 to 5 show details of the tting partly from dierent points of View and partly in section.

The rising pipe 9 mounts up to the tap 6, in which are the plug 7 and t-he outiow-pipe 8. There is also in the tap an air-pipe 10, iixed concentrically around the rising pipe 9. The atmospheric air in the Siphon-bottle 11 can therefore reach the air-escape formed by the screw 13 provided in the tap, and when the screw 13 has been screwed out to a slight extent the air can escape through the channel 14 therein. Around the air-pipe 10 is a mantle 14, at the upperend of which is a ring 15, which can be made to revolve, and a ring 16, which is screwed on. At the lower end of the mantle 14 is a flange 3l, which passes over the neck of the bottle 17. An india-rubber stopper 18 is passed over the lower end of the air-pipe 10 and fixed by means of the screw-nuts 19,. When the ring 16 is scewed away from mantle V14, it presses against the tap 6, and consequently presses the mantle 14 against the rubber stopper 18. The rubber stopper is thereby iiattened and its circumference increased, so that its sides press against the neck 17 of the bottle, and thus fix the whole Siphon-fitting to the said neck. When it is desired to take the fitting o, the ring 16 is screwed down into the mantle 14, so that the rubber stopper can expand in the direction of its axial length and decrease its circumference. Then it can easily be withdrawn from the bottle-neck and the armature thus be taken off.

To prevent unauthorized unscrewing of the air-escape 13 and also unauthorized screwing down of the ring 16 into the mantle 14-rhat is, to prevent the fitting being taken from the neck of the bottle-the following device is provided: j

The screw of the air-escape 13 is provided with a groove 2O and can be opened by means of the end 21 of the key. (Shown from two points of View in Fig. 5.) The cap 22, (shown in Fig. 3 from two points of view,) which has a hooked-shaped projection 23, is placed over the screw of the air-escape. Inserted into the revolving ring 15 is a screw 24, in the head of which are a hole 25 and a pin 26. The screw 24 is turned byinserting the projection 28 of the key (shown in Fig. 5) into the hole and turning it. The hook-like projection 23 of the cap 22 hooks onto the screw 24. When the screw 24 is screwed tightly into the ring 15, the latter presses the projection 23 against the edge of the ring 16 and the edge 29 of the mantle 14, so that unauthorized unscrewing of the ring 16 is prevented and the fitting cannot be taken off the bottle. At the same time the screw of the air-escape is covered up and unauthorized opening thereof prevented.

Having thus described our invention, the followingis what we claim as new therein and desire to secure by Letters Patent:

` 1. Animprovement in Siphon-fittings consisting of a mantle 14 placed on the air-pipe of the tap 6, of a ring 16 screwing into the said mantle and abutting against the tap, of a rubber stopper 18 fixed to the air-pipe by means of screw-nuts 19, the said stopper being attened when the ring 16 is screwed out of the mantle 14 so that its sides press against the inside of the bottle-neck. i

2. The employment in Siphon-fittings of a mantle 14 which is placed on the air-pipe and into which a ring 16 is screwed and of the rubber stopper 1S which is compressed when the ring 16 is unscrewed, further of a movable ring 15 on the mantle 14 with a screw 24 inserted into it and of a hook-like projection 23 which hooks onto the latter and the other IOO end of which forms a o ap 22 which covers the In Witness whereof we have hereunto set screw of the air-escape 13, the said hook-like our hands in prese-nee of two witnesses.
