APPARATUS FOR SEAL-INC: PRESERVING GLASSES AND S IMILAR VES SELS Filed-Aug. 3, 1956 I I In-vep'tor": fi hzi Patented July 20, 1937 UNETE STAES APPARATUS FOR SEALING PRESERVING GLASSES AND SIMILAR VESSELS Friedrich Schimmel, Berlin, Germany Application August 3, 1936, Serial No. 94,062 In Germany August 1, 1935 1 Claim.

As is known, spirit burners with non-luminous flame, in which air is supplied to the burner tube by a rubber ball, are employed for sealing preserving glasses and similar vessels. These known burners are open to the objection that they do not produce the necessary properly shaped flame, because the holes are arranged either only laterally or only on the front and moreover as no supporting device which, when the apparatus is being used, rests on the edge of the glass, is provided. The result therefore is that, when the pressure is exerted on the rubber ball, the apparatus carries out an oscillating movement in sideward direction. Consequently, the flame produced does not come into the air space between the lid and the goods to be preserved but spurts out laterally in irregular manner. However, it is very important when preserving that the oxygen present in the preserving glass is quickly and completely burned so that a sufficiently rarefied air space is produced as is necessary for sealing the glass in. a satisfactory manner.

Experiments have shown that this objection is overcome when the non-luminous flame passes out not only laterally or only at the front, but assumes the shape of a ball owing to a suitable arrangement of the combustion holes.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:-

Fig. 1 shows the apparatus in elevation partly in longitudinal section.

Fig. 2 is a cross section of the support taken on line II of Fig. 1.

Fig. 3 shows a modified means of fixing the adjustable support with bearing surface.

Fig. 4 is a cross section on line 11-11 of Fig. 3.

According to the invention the air feed tube (1 has on its front end a widened portion (1 which terminates in a burner cage d so that a wick 2 wrapped around this cage (1 fits tightly in the space between the burner tube 6 and the air feed tube d, and the non-luminous flame emanating from the wick passes out laterally and at the,

front through holes in the burner tube and thus assumes a spherical shape.

a designates the rubber ball with valve a for supplying air into the apparatus, this ball being connected with a socket b by means of a clamping ring 0. The air feed tube cl extends through this socket b. On the narrowed front end b of the socket the burner tube e is arranged which serves as casing tube and has in its front portion and in its side wall perforations.

In order to rapidly and completely burn the oxygen present in the preserving vessel, the apparatus must be firmly supported. So as to prevent the apparatus from swinging to and fro laterally in an undesirable manner when pressure is exerted on the rubber ball a, a support 9 is provided on the burner tube c. This support comrises a clip 1 slidable on the tube 6 and adjustable according to the size of the preserving glass, the two ends of this clip being held together by a screw and nut g and having lateral arms h curved to conform with the shape of the preserving glass.

Instead of the ordinary screw and nut 8 shown in the drawing a screw with winged nut may be employed. The clip 1 may also be provided with a hinge so that the support has a joint which enables the arms h to be easily brought into any desired position on the edge of the vessel. The support g may also be guided in a slot m provided in the burner tube e (Figs. 3 and 4).

In order to prevent the air supplied to the burner from flowing back through the air feed tube e into the rear space between the burner tube e and the air feed tube d and to thus ensure that the whole of the compressed air is fed to the flame, a packing disc k: is provided behind the wick i.

I claim:--

An apparatus for closing preserving glasses and similar vessels, comprising in combination an air feed tube, a widened portion on the front end of said tube, said widened portion constructed as a burner cage, a burner tube surrounding said air feed tube and having at its front portion perforations in the side Wall and front end, a wick wrapped around said cage and filling the space between said cage and said burner tube, a packing disc on said air feed tube at the rear of said wick adapted to shut off the communication between the front and rear ends of said burner tube, a rubber ball on the rear end of said burner tube adapted to supply air to said cage through said air feed tube, and a support on said burner tube adapted to bear against the edge of the preserving glass to prevent the undesirable to and fro lateral movement of the apparatus when pressure is exerted on said rubber ball.
