AUGUSTUS D. SOHLESINGER, OF COLLEGE POINT, ASSIGNOR TO THE INDIA RUBBER COMB OOHPANROF NEW YORK, N. Y.

POCKET FLASK.

SPECIFICATION forming part of Letters Patent No. 468,829, dated February 16, 1892. Application filed September 30, 1891- Serial No. 407,240. (No model.)

To ctZZ whom it may concern:

Be it known that I, AUGUSTUS D. SOHLES- INGER, of College Point, Queens county, and State of New York, have invented a certain new and useful Improvement in Pocket- Flasks, of which the following is a specification.

My improvement relates to pocketflasks having a body of glass and a jacket of hard [0 india-rubber.

The improvement consists in extending the glass laterally in the form of a lip over the mouth portion or outer end of the jacket, and in combining with such lip a packing extending over the same, and a cover lapping over the packing and lip and engaging with the jacket.

In the accompanying drawing the figure is a sectional side elevation of a flask embodying my improvement.

A designates the body of the flask. It is made of glass and may be of the usual form.

B designates a jacket applied to the exterior of the upper portion of the body A. This jacket is made of hard rubber and tightly fits the body A at all points.

O designates a cup, which may be made of hard rubber. It is fitted to the lower part of the body A below the jacket B, and may be removed and replaced at will. The upper end of the jacket B is made in the form of a boss or cylindric head b, on the exterior of which a screw-thread is formed. The body A at the upper extremity is extended outwardly in the form of a lip a, lapping over the outer end of the boss or head b.

D designatesa packing, consisting of a disk, of leather or other suitable material, applied to the outer surface of the lip a.

i E designates a cover, which may be made of hard rubber. It incloses the packing D, and has a rim which engages the screw-thread of the boss or head 6.

It will be seen that by my improvement the glass is extended over the hard-rubberjacket at the end, through which the contents of the flask pass, and hence that such contents do not necessarily come in contact with the jacket. Moreover, the packing is applied directly to the glass, and the force exerted dur- 5o ing the application of the cover by means of its screw-thread will not tend to draw the jacket off the glass body, because of the lip which is between the outer end of the jacket and the cover.

My improvement dispenses with the necessity for cement at the mouth of the filask. Cement is always objectionable, because when flasks are made in the ordinary manner the cement is more or less exposed to the con tents of the flask. The latter rot the cement, and the cement is liable to more or less contaminate them.

Of course my improvement is not strictly confined to the use of hard rubber for the jacket B, but can be used with jackets of other material.

What I claim as myinvention, and desire to secure by Letters Patent, is

In a pocket-flask, the combination of a body of glass, a jacket of hard rubber or analogous material tightly fitting at all points on said body, a cover engaging with said jacket and a packing within the cover, the said glass body being provided at its mouth with a laterally-extending lip, which forms on one side a shoulder against which the outer end of the jacket bears and the other side forms a bearing against which the packing in the cover tightly fits, substantially as specified.

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

AUGUSTUS D. SOHLESINGER.
