CANTEEN.

.SPECIFICATION forming' part 0f Letters Patent No. 703,654, dated July 1, 1902.

4Application led August 30, 19,00. Serial No. 28,507. (No model.)

To afZZ whom t may concern:

Be it known that I, ALMONJHALL, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Canteens; and'l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and ,to the figures of reference marked thereon, which forms a part of this specification.

Troops in the field are rarely able to obtain pure water for drinking'and are frequently compelled to drink water which is dirty, stagnant, and dangerous to health and life.

My invention relates to and has for its object a canteen which will serve as a filter and as a water-purifier and which, no matter how stagnant and unclean the water may be when put into the canteen, will furnish from the canteen water which is clean, purified, and free from micro-organisms, disease-germs,and other suspended matter. p

It has heretofore been proposed to supply army-canteens with filters and to force the water through the iiltering-body either by the gravity of the water or by the suction of the mouth of the drinker; Vbut it is obvious that to permit such filtration the filteringbody must beso porous as to fail to effectually arrest diseasegerms and microscopic particles.

A further object of my invention is to furovercome this difficulty and in which the porosity of the filtering-body maybe as small as may be desired and in which the filteringbody will consequently arrest the finest particles of suspended matter.

I attain these objects by means of the de- Vices and arrangement of parts hereinafter described, and shown and illustrated in the accompanying drawing, in which the single figure represents mycanteen in central longitudinal vertical section.

In the drawing, l is the body of a canteen of the usual or of any preferred form'.

2 is a tube of unglazed porous porcelain or earthenware of the well -known Pasteur `teeni -tom of the porous tube 2.

. type, except that it may be smaller in diameter and shorter.

-3 is a screw-cap for the nozzle 4 of the can- Secured tothe bottom of the cap 3 is a tube 5, which passes'down through the bot- The bottom of the tube 5-is screw-threaded, and upon this p0rtion is screwed a cap or nut 6. When the Anut yt is screwed up tightly, the filteringvtube is pressed endwise between the nut 6 -at y11,I and engages the same interior thread of the cap 3 which screws onto the neck or :mouth/JE of the canteen.

The gasket 8 serves for both-the tube 2 and the tube 9. The

shoulder formed by the flange 9a on the tube 9 rests uponfthe top of the neck or mouth of the canteen, and between these two partsis interposed agasket 12. At bottom the tube 9' isfclosed, as at 14, and from this bottom extends downwardly, almost to the bottom of thecavity of the canteen, a small tube 15, there being a clear opening through the tube 15 into the chamber of the tube 9. The top of the screw-cap 3 is formed or provided with a cup or chamber 16, yhaving a removable cover 17, consisting, preferably, of a screwcap. The finterior vof' the chamber 16 communicates with. the interior of the lteringtube 2 vthrough openingl 18, tube 5, and the holes-therein, 5.

19 is a sheet-metal tube provided at top with a screw-threaded flange 20, whichv is screwed into a threaded cap 21, which cap is screwed onto a neck or nozzle of the canteen, as at 22. At bottom the tube 19 is-provided with a valve 23, which is held normally seated against valve-seat 24: by means of a spring 25. The valve and the'spring are contained'in a small tube 26, connected with the interior of the tube 19 and having an opening at bottom, as at 27, near the bottom of the chamber of the canteen. In the tube is a plunger 28 upon the lower end of a rod 29, which ex- IOO tends up through an opening in the cap 21 and is provided at top with a handle 30. The cap is recessed in its top and is provided with a supplemental cap 31, which is recessed in its bottom. The two caps being screwed together, as at 32, provides an air-tight cavity between the two caps which contains the handle 30. A suitable gasket is interposed between the two caps, as at 33. The cap 31 is not absolutely essential, but serves to prevent escape of confined air through the airpump in case of leak through the valve 23.

The operation of my device is as follows: Vhen the canteen is to be filled, the screwcap 3 is unscrewed from the neck and removed, carrying with it the casing-tube 9 and its contents. The canteen is now filled in the usual manner, and the cap is screwed back in place until the gaskets, which are designed to make air-tight joints, are sufficiently compressed. The cap 3l is now removed, and by means of the handle 30 the plunger 2S is rapidly reciprocated in the tube 19. At each upward stroke exterior air passes the soft flexible flange of the plunger, and as the plunger is driven down the fiange expands by the resistance of the air in front of it and the air is driven through the yielding valve 23. This valve at the end of each downstroke of the plunger by force of the action of the spring 25 and the back pressure of the air is immediately reseated. The continued action of the air-pump here described will quickly place the contents of the canteen under great pressure. The water is now forced through the bottom of the tube 15 up into the annular chamber of the tube 9, surrounding the filtering-tube, and the air-pressure upon the water forces the water through the pores of the filtering-tube 2. From the filtering-tube the water ascends through the openings 5a into the cup or chamber 16 of the cap 3. lVhen the cup 16 is full, if the screw-cap is screwed to place, the filtering operation will for the time being cease until the cap 17 is again removed. By removing the cap 17 the contents of the chamber 16, together with the contents of the filtering-tube, may be drunk, as from a bottle. It will be seen that as the tube 15 at the bottom of the filter-case 5 extends nearly to the bottom of the canteen the air-pressure will drive practically all of the water in the canteen up into the case surrounding the filtering-tube, so that the entire contents of the filter will be forced against and through the filtering-body. Y

As the air from the air-pump is discharged into the canteen at its bottom the air in minute bubbles ascends through the water, thus aerating and purifying the Water. If when foul water in the canteen is under air-pressure the canteen be vigorously shaken, the water will be further aerated, it being found in practice that very stagnant water will in a moment become remarkably sweetened and purified by the thorough admixture of the water and compressed air.

It will be obvious to those skilled in the art that many equivalent methods of securing a filtering-body and an air-pump in a canteen with air-tight joints will suggest themselves, and I do not, therefore, limit my claims to the precise devices here described for obtaining these results, nor do I limit my claims to a chamber in the cap of the canteen for the reception of the filtered Water, as it will readily be seen that the filtering-body may be made large enough to form of itself a chamber for the reception of filtered Water and for a drinking-cup or that a portion of the interior of the canteen may be utilized for receiving and holding the filtered water until it is to be used.

The filtering tube or body may be of any preferred form; but a small tube is preferable, as it is lighter and occupies less space. The large heavy cup necessary when gravity or mere partial vacuum is relied upon for forcing water through the filteringbody is thus dispensed with.

The form of air-pump here shown is preferred, as it is powerful, cheap, simple, and durable; but other forms may be substituted without departing from my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A canteen for hand manipulation comprising inits construction a body portion, two chambers inclosed within the cavity of the body portion, one of said chambers being for unfiltered Water and the other chamber being for filtered water, a filtering-body interposed between and in communication with said two chambers, and an air-pump connected to the chamber for unfiltered water.

2. In a canteen, a filtering-body, a casing inclosing the filtering-body, a'chamber for unfiltered water, a chamber for filtered water, connections between the interior of said casing and the lower part of the chamber for unfiltered water, and an air-pump adapted to compress air in said latter chamber.

3. A canteen having a body portion provided With a cavity for holding water and an air-pump having its discharge-outlet extended into the cavity of said canteen to a point near the bottom thereof to force air into the cavity of the canteen below the water-level therein to thereby purify 'the water by the upward passage of air through the water. Y

4c. A canteen provided with a body portion having a cavity, a nozzle or neck and an airpump extended through said nozzle or neck and supported thereby within the cavity of the canteen to force air into the cavity of the canteen below the Water-level therein to thereby purify the water by the passage of air through the water.

5. A canteen provided with a body portion having a cavity, a nozzle or neck secured to the body portion, and an air-pump supported by said nozzle or neck and extended into the cavity of the canteen, the discharge-outlet of said air-pump being extended to near the bottom of the cavity of the canteen to force air IOO pump supported therein, a separable screwcap vfor the nozzle, having in its interior-a chamber, a plunger for theair-pump, and a r 5 handle for the plunger inclosed in said separable screw-cap.

9.l A canteen provided with a body portion having a cavity, a nozzle orvneck secured l to the body portion, an air-pump extended zo `through the `nozzle or neck 4and extended Within the cavity, and means fordetachably connecting said air-pump with the nozzle or neck. v
