T MILLIE PATENT HOLDING CO. INC.,

OF NEW YORK, N. Y., A CORPORATION OF TEA. CARTRIDGE.

Application filed February '1, 1923. Serial No. 616,317.

T 0 all whom it may concern:

Be it known that I, BENJAMIN Hmsorr- HORN, a citizen. of the United States, and resident of the city of New York, in the county of Bronx and State of New York,

have invented certain new and useful Im provements in Tea Cartridges, of which the following is a specification.

The present invention relates to improvements in tea cartridges for percolating or extracting the flavor from tea-leaves or coffee. The invention pertains'more particularly to that type of cartridges. which is described in U. S. Letters Patent No. 1,310,796, granted to me on July 22, 1919.

In this patent a cartridge is described, comprising a bag of textile fabric, having its mouth drawn into folds, the mouth of the bag being closed by a metal strip, in the form of a ring, which engages and compresses the folds, in combination with a suspending string which is attached to said bag by said strip. In making these cartridges, obviously, first a bag must be formed on a sewing machine from a piece of textile fabric.

The main. object of the present invention is to form a tea cartridge from a piece of textile fabric without first producing a bag, thereby greatly reducing the cost of manufacture.

With these and other objects in view, which willmore fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings. it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim,

without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure l is a plan view of a piece of fabric. front which the container of the cartridge formed; Fig. 2 is a perspective View i the container before its mouth is closed;

and Fig. 3 is an elevation of a completed tea cartridge, constructed in accordance with the present invention.

In producing the cartridge, first a iece 10 of open-mesh textilefabric, preferably of square or quadrangular configuration, is cut from a strip, tea-leaves or coffee, sufficient for a single brewing, being placed centrally thereon, and the edges of the said fabric piece gathered together, as shown in Fig. 2 of the drawings, whereby a bag-like receptacle 11 is obtained, within which the tealeaves or coffee are confined. The mouth of the receptacle so formed is then closed, by applying thereto a metallic strip 12, that is shaped to assume the form of a ring, which embraces the folded portion of the receptacle below its mouth, holding the folds under compression, so as to prevent escaping of the contents. The strip must, obviously, be made of non-corroding metal or of a metal that is properly prepared to prevent corrosion. For the purpose of facilitating the handling of the cartridge, there is fixed thereto a flexible means, such as a string. 13, to which is attachedat its free end a handle 14, for instance of cardboard. This string serves also as the means for suspending the cartridge from the receptacle,

such as a tea-pot or coffee-pot, in which the extraction is to take place. The string is secured to the cartridge by placing it against the folded mouth portion of the receptacle 11 before the strip 12 is formed.

From the foregoing it appears that the receptacle 11 is seamless, and that the ringshaped closure strip 12 constitutes the means which holds the gathered edge portions of the fabric piece under compression, to form a receptacle therefrom.

In brewing tea or coffee with the improved device, the cartridge is taken hold of by its handle 14 and lowered into a pot, the free end of the string and handle being permitted to hang over the mouth of the ot, after which its cover is put in place. he cover thus holds the outer end of the string and handle ready for further operation. Into the pot is poured a suitable quantity of boiling water, either before or after the insertion of the cartridge. When sufficient essence has been extracted from the'tealeaves or coffee within the cartridge, the pot cover is removed and the bag withdrawn by grasping its handle 14.

What I claim is :-1-

A device for extracting essence from tealeaves or coffee, comprising a piece of textile fabric having its edges gathered to gether so as to form a seamless receptacle,

and a metal strip engaging and compressing the mouth portion of the receptacle so formed so as to close the same.

Signed at New York, in the county of New York and State of New York this 23rd day of February, A. D. 1922.

BENJAMIN HIRSCHHORN.
