TEA CARTRIDGE.

Application filed October 26, 1923. Serial No. 670,857.

To all whom it may concern Be it known that I, BENJAMIN HIRSCH- 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 Improvements in Tea Cartridges, of which the following is a specification.

The present invention relates to cartridges for percolating or extracting the flavor from tea leaves or coffee. The invention pertains more particularly to that type of tea-cartridges, which is described in U. S. Letters Patent No. 1,310,7 96, granted to me on July 22, 1919. I

In the Letters Patent mentioned, a device for extracting essence from tea leaves or coffee is described, comprising a bag of textile fabric which contains a quantity of tea leaves or cofiee just sufiicient for a single brewing. The mouth of the bag is drawn into folds and closed by a metal strip, engaging and compressing said folds, thereby closing the mouth of said bag, said strip attaching at the same time a suspending string to said bag.

The main object of the invention is to provide a cartridge the bag of which is in the form of a tube, one end of the tube be- 30 ing closed by a metal strip of the typeabove referred to, while itsother end isclosed by the suspending string.

IVith these and other objects in View, which will more 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 iilustrated in the accompanying drawings, in which Figure 1 is an elevation of a tea-cartridge constructed in accordance with the present invention; Fi 2 is an elevation of the tube of which the gagis formed; and Fig. 3 is a section taken on line 33 of Fig. 2, on a larger scale.

In the drawings, the numeral 10 indicates a tube of open-mesh textile fabric, such as for instance cotton, it being, preferably, made of a single piece of fabric that is folded along one of its longitudinal edges, denoted by the numeral 11, the meeting longitudinal edges 12 of the 'two plies being 'joined by a row of stitches 13, which runs parallel to the said meeting edges.

'In preparing the cartridge, one of the ends of the tube is gathered into folds and a metal strip 14 applied thereto. This metal strip is shaped to assume the form of a ring, embracing the folded portion of the tube so as to hold the folds under compression. In this manner a bag is formed, tea leaves or cofiee fora single brewing being then placed into the same. The mouth of the bag is then closed by puckering the same and tying around the same one end of a string 15, to the other end of which is attached a handle 16 of pasteboard or like material, for a purpose hereinafter to be described.

In brewing tea or coffee with the improved device, the cartridge is taken hold of by itshandle 16 andlowered into the brewing rece tacle, the free end of the string and handle ein permitted to hang over the mouth of t 1e receptacle, after which its cover is put in place. The cover thus holds 85 the free end of the string and handle ready for further operation. Into the receptacle is poured, either before or after the insertion of the cartridge, a suitable quantity of boiling water. When sufficient essence has been extracted 'from the tea leaves or coffee within the cartridge, the cover of the brewing receptacle is removed and the bag withdrawn by rasping its handle.

ll hat I claim is A device for extracting essence from tealeaves or coffee, comprising a tube of textile fabric having both ends drawn into folds, a metal strip encircling and compressing the folds on one end of said tube so as to close the same, astring having one of its ends tied around the other end of said tube for closing the same, and a handle attached to the other end of said string.

Signed at New York, in the county of 105 New York and State of New York, this 16th day of October, A. n. 1923.

BENJAMIN HIRSCHHORN.
