AUGUSTA MERIEL MELVILLE-I-IAMILTON, 0F MEDINDIE, SOUTH AUSTRALIA, AUSTRALIA.

WATER-BOTTLE -O-R WATER-BAG.

Specification of Letters Patent.

Application filed September 10, 1910.

Patented Mar. 5, 1912.

serial No. 581,400.

To all whom it may concern:

Be it known that I, AUGUSTA MERIEL MEL- VELE-HAMILTON, a subject of the King of Great Britain, residing at Robe Terrace, Medindie, State of South Australia, in the Commonwealth of Australia, have invented certain new and useful Improvements inV or Relating to Tater-Bottles or later-Bags, of which the following is a specification.

This invention relates to water-bottles or water-bags, particularly adapted for military purposes.

I-Ieretofore, water bottles have usually comprised merely a receptacle of suitable shape and material provided with an orifice or a nozzle for drinking and filling purposes, the said orifice being closed by a cork or plug. During military campaigns or maneuvers such water bottles are frequently lled from any available source regardless of its character or quality; the results of drinking water from indiscriminate sources are toov well known to need further statement. Further disadvantages of the water bottles heretofore in use have also presented themselves, in that it is somewhat inconvenient to drink from the same without wasting the contents, either by spilling, or by unavoidably taking more than is required into the mouth. Furthermore, when a soldier for instance is in a prone position it sometimes becomes a matter of considerable inconvenience if not difficulty to raise the bottle to a position from which the contentscan be obtained. It also requires some skill to completely empty the bottle owing to the nature and position of the outlet orifice or nozzle.

The present invention has for its chief object to overcome the dangers of obtaining water in the manner hereinbefore referred to by providing the bottles with means for filtering the water contained therein.

A further object is to construct the waterbottle in such a manner as to afford ready means of inspection so that the interior may be kept perfectly clean and also to render the construction of such a character that any desired quantity of the contents can atall times be consumed without waste, while permitting the same to be readily obtained from all positions of the consumer and the entire contents to be exhausted so that the bottle may be completely refilled with fresh water as often as possible.

According to this invention, the bott-le or container is fitted with a filter comprising a suitably shaped hollow block of any appropriate material inclosed in a metallic casing preferably of cylindrical form and having perforations in the inner end of same. The filter is adapted for being carried by the mouthpiece which is Yprovided with a tube so arranged as to enter the hollow filter block. The said tube extends toward the bottom of the filter; the arrangement being such that all water in the bottle must pass to the consumer, through the iilter block and the tube, so that all the water is filtered before it is consumed. Furthermore, the provision of the long tube enables the liquid to be readily and comfortably obtained no matter in what position the consumer may be. In certain cases the filter may be dispensed with in which case the contents of the bottle are consumed directly through the aforesaid tube.

In order that the said invention may be clearly understood and readily carried into effect, I will proceed to describe thesame more fully with reference to the accompanying drawings, in which Figure l is a view partly in elevation and partly in section illustrating a water bottle embodying the features of the present invention. Fig. 2 is a similar view illustrating the modified form of the bottle hereinbefore referred to.

The bottle or bag A is provided with an opening or aperture a which ap roximately occupies the full width of the ottle. The

aperture may be disposed as shown toward one end of the bottle or it may be arranged in any position between the two ends of the bottle. The said aperture is adapted for being closed by means of a screw or other suit-able cap such as .b the annular wall or stem o of which is screw-threaded both internally and externally. The external thread engages in an internal thread in a ring c around the aforesaid opening or aperture a. The internal thread inthe ring part b enl gages with a screw thread on the casing d of the filter e. Washers of leather or other suitable or yielding material may be provided between the adjacent surfaces of the cap Z) and the bottle or where necessary.

Projecting from the outside of the screw cap b is a tubular nozzle, having a removable cover g attached preferably by a bayonet joint. The removable cover g is retained from loss when removed from t-he nozzle by means of a chain connection as shown. The

hole through the nozzle is screw threaded for the reception of the end of the tube 7L which is secured in the said nozzle and extends almostto the bottom of the interior or cup of the filter' block.

A passage 7,' is provided in the cap Z) to serve as an air vent to the body of the bottle, as water is withdrawn therefrom. The said passage i is normally .closed by means of a wing .or projection which may form part of the cover g or the passage may be closed by means of a separate plug.

The filter block c rests upon the bottom of the casing CZ and is formed with a flange 7s at the top so as to close the annulus between the block and the Vcase d. The latter extends toward the bottom of the bottle, leaving suflicient space for water to enter between the perforations Z and the bottom yof the bottle. The water enters the casing l through these perforations and thence filters through the block e into the interior space or cup from whence it can be withdrawn. through the tube z. The filter block e is of such a length as to have 'the top flush with the top of the casing CZ and a ring or washer m of any suitable substance is provided so as to insure a perfect closure of the annular chamber. The casing d with the filter c and t-he tube 7L may be readily removed for cleaning purposes as will be apparent from the drawings.

If it is desired to prevent tampering with the internal parts of the chamber l the latter may be arranged as an integral part of the cap b, the filter' block being previously inserted therein, while the tube 7L may be fitted therein so as to permit of the outward withdrawal of the same. Such construction is obvious and needs no special illustration. Y

In Fig. 2, the filter is dispensed with and the bottle remains with the advantages of the long tube 7L for facilitating drinking without having to tilt the bottle or assume awkward and uncomfortable positions for drinking. The filling orifice may be arranged centrally or toward one side or end and is screw threaded for the reception of a plug or stopper in which the aforesaid tube h is mounted so as to project into the bottley approximately to or near the bottom thereof. The plug and orifice are of somewhat large diameter so that a large filling aperture is provided. The tube IL may be detachab'ly mounted Yin the lug or stopper Y verting the bottle, and without having to exert any great or special force of suction.

The water-bottle or bag may obviously be made of canvas, leather or other similar impervious material and may also be provided with any suitable arrangement of strapping for attachment to the person, or to the saddle or harness or for ambulance use.

`What I claim and desire to secure by Letters Patent of the United States is 1. A water bottle having a filter, and a suction tube within the lter, the relative sizes of the filter and tube being such as to form a chamber for the accumulation of filtered liquid, said tube communicating with said chamber only near vthe bottom thereof, whereby the accumulationof filtered liquid may be removed by suction.

2. A water bottle comprising a body portion having a large filling aperture, a removable cover having a depending wall engaging. with said filling aperture, an air vent being provided in said cover, a nozzle on said cover, a cap for closing said air vent and nozzle,and a continuous suction tube connected to said nozzle and extending approximately to the bottom of the water space of the bottle, said tube having an inlet opening only at its lower end.

3. A water bottle comprising a body portion, a large filling aperture in said body portion, a removable cover having a depending wall engaging with said filling aperture, a nozzle on said covering, a perforated casing screwed to said cover and a filter tube arranged within said perforated casing for filtering the water passing through the nozzle.

Li. A water bottle comprising a body portion having a large filling aperture, a removable cover having V-a depending wall engaging with said filling aperture, an air vent being provided in said cover, a nozzle on said cover, a cap for closing said air vent and nozzle, a perforated casing screwed to said nozzle, a filter tube arranged within said perforated casing and a tube arranged within said filter tube and extending to the. bottom thereof. j j
