arramrus AND PACKAGE ron rommm somr'rrons BY uncommon.
To all whom it may concern:
Be it known that I, JOHN B. CLERMoN'r,
of New York, in the county of Bronx, and in the State of New York, have invented a certain new and useful Improvement in Ap paratus and Packages for Forming Solutions by Percolation, and do hereby declare that the following is a full, clear, and exact description thereof.
The object of my invention has been to provide an apparatus for forming solutions by percolation and a package of material for use in such apparatus, which shall be adapted, among other uses, for use in makand which shall have any or all of the fol owing advantages! That of great simplicity; that of enabling infusions to be made of such substances as cofi'ee by passing the water or other liquid but once through the material being leached;
' that of enabling the material being leached to be introduced into the apparatus and remain therein in the form of a package so as to provide not only for simplicity of 26 pperation, but for easily cleansing the apvation, a vertical sectional view, and a bottom plan view of a cartridge or package ada t'ed for use with said apparatus.
y invention is capable of use for many different purposes, and while I have chosen for illustrating it the best form of apparatus known to me, suchapparatus and packa e for use therewith, are to be regarded as on y one of many possible embodiments, and my invention is not to be restricted thereto.
The illustrated embodiment of my invention is adapted particularly for the manufacture of coffee. In such embodiment, I
have shown a base lwhich is adapted to fit over a cup or othervessel into which the made coffee is to drop, such cover having. a
' flange 2 at its outer edge to prevent its escaping from off the'cup. In the center of the base is a sleeve 3 which is solderedor otherwise. fastened to the base, and which is provided with an inturned flange 4 at its Specification of Letters Patent. Patented A 11 1922 Application filed January 11', 1916. Serial in. 71,418. 5
lower edge. pot or body 5, is provided w th a neck 6 that is adapted to be received within the sleeve, and to rest upon the flange 4, the neck 6 also having an inturned flange 7 at its lower edge. A bayonet joint is formed between the sleeve and the neck by plus 8 on the neck, adapted to engage cam slots 9 1n the sleeve. A cover 10 is provided for closing the upper end of the pot.
The coffee or other material from which the infuslon is to be formed is provided in what I term cartridges, or packages adapted to be received within the neck of the pot, such packages preferably having substantlally vertical walls llthat are sufiiclently mpervious to water or other infus- 1I1P liquid so as to compel all the water escaping from the lower end of the neck to is seated a disc 14 of material which will permit the passage of the water or other lniuid while preventing the escape of the so id material, and such disc may be formed of unsized paper like blotting paper. The paper or other material forming the shoulder 13 is preferably turnedover underneath the disc 14 to, secure it in place. A
disc of porous paper may also be used to close the perforations'lZ in the cartridge. Both the upper and lower ends of the car-- tridge may be sealed as by seals 15 and 16 formed, for instance, of paraffine tissue pa er, and which are easily torn ofl.
n the use of m apparatus and cartridge, the cartridge, loa ed with pulverized cofl'ee, is made ready for use by tearing off the thin seals 15 and 16, and is placed in the neck 6 of the pot by inserting it in the neck when the pot is inverted, so that the shoulder 13 of the cartridge rests'on the flange 7 of the neck. The sleeve 3 is then placed over the neck and by means of the bayonet joint is caused to clamp the shoulder 13 and filter disc 14 between the flanges 4 and 7, so as to make a substantially water-ti ht joint.
The pot is then supported upon t e cup on T other receptacle which is to receive the cofiee extract, and the required amount of water is poured into the pot through its top. The water percolates through the cartridge, and as it can only enter through the perforations 12 and only escape through the porous paper disc, all the water has to pass entirely through the layer of coffee and is all thus equally presented to the pulverized coffee. The result is that the water is in contact with the coifee long enough to take up its beneficial extracts but is not, in contact long enough to dissolve its harmful in gredients. In this way, although the water my pass but once through the ground coffee, fluid coffee of the finest flavor may be obtained and with the least amount of deleterious substances therein, and it is found that substantially all of the beneficial materials in the coffee can be extractedwith the single passage of the Water therethrough.
It will be seen that my apparatus and cartridge have, among others, the following advantages, in addition to those just described:
The use of the cartridge enables the material being leached to be introduced into the apparatus and removed therefrom Wltlh out ever losing control of the material, so that not only is the operation of charging and emptying the percolator performed with great simplicity and cleanliness, but an infusion is obtained of the greatest possible strength, and all the material being leached is insured of thorough and equal treatment by the water or other liquid. .Regulatin the size of the cartridge is' a convenient an accurate means for measuring the proper amount of coffee or other material to form the desired quantity of the infusion. The apparatus is of great simplicity and can be used out of doors without other facilities than those for supplying hot water.
Itis obvious that various changes can be made in the above described embodiment of my invention which would be within the scope of the invention. For instance, the cartridges may be charged with more than a single substance, such, for example, as with coffee and milkin a dried form, as well as sugar.
I claim:
1. In a percolatin nation of a receptac e having a cylindrical neck, a'cap having a cylindrical sleeve adapted to fit said neck, said neck and sleeve hav- 1n sald neck and sleeve, means for forcing said flanges toward each other, and a cartridge having a pervious topand bottom, said cartridge having a shoulder adapted to be clamped between said flanges.
2. In a percolating a paratus, the combination of a receptacle iiaving a cylindrical neck, a cap having a cylindrical sleeve adapted to fit said neck, said neck and sleeve having inturned flanges on the lower end of apparatus, the combiinturned flanges on the lower end of said neck and sleeve, a bayonet joint adapted to force said flanges toward each other,
. and a cartridge having a pervious top and bottom, said cartridge having a shoulder adapted to be clamped between said flanges.
3. In combination, a receptacle adapted to contain liquid, a base located beneath said, receptacle and having portions shaped to fit over a receiving vessel, said receptacle and base having parts adapted-to receive therebetween an independent cartridge containing material to be treated, and a bayonet pin gether said receptacle, and base.
4. In a percolating apparatus, the combination o a receptacle, and a base each having a cylindrical neck or sleeve, said them, and a cartridge having a pervious top and bottom, said cartridge having a. shoulder adapted to be clamped between said flanges.
In testimony that I claim the foregoing I have hereunto set my hand.
