To all whom it may concern:
Be it known that I, James LANGIUN CLARKE, a subi'ect of the Kill of. Great Britain and Ire and, residing at o. 25 Clarendon Square Leamington, in the county of Warwick, ngland, have invented a new or Improved Drinking-Tube, of. which the followmgis a specification.
This invention relates to a new or improved drinking tube-a plicable for use with receptacles such as fla and bottles, glasses and the like. I 1
The invention consists of a drinking tube adapted to be confined within a bottle and provided with a resilient member adapted to raise it when the stopper, ea or cork of the bottle or flask is remove so that the tube will project sufliciently above the mouth of the bottle. to ermit said tube to be placed in the mout of the drinker and permit it to .be replaced or nt back to its normal position in the bott e or flask when the stopper, cap, or cork is replaced, whereby the necessity fora cup is obviated, or a medicine glass may be dispensed with, in the case of medicine bottles with measurement marks thereon, nor is it necessa to tip up or incline the flask or bottle when drinking.-There may be rovided more than one drinking tubeto a k or bottle so that several rsons may drink from the same receptac e without it being necessary for each tube.
In order toenable this invention to be readily understood reference is made to the accompanyin drawings in which Figure 1 s ows in side elevation a medicine bottle having one of the improved tubes.
Figs. 2, 3' and 4 are elevations. of modified forms of tube. "Figs. 5 and 6 are similar views of a drinking flask in the open and closed positions res tively and fitted with another modified' cm of drinking tube.
Fi 7 afid 8- are views, partly in section an partly in elevation of further modified forms of tube and Fig. 9 is an elevation of yet another modificatlon.
In carrying the invention .into efl'ect as seen in Fig; 1 the drinking tube a is. suitably made of glass, metal, vulcanite, or other 1 suitable material, and an of the tubes shown in the drawings may provided with a groove 1) or rounded nozzle 0 at the upper end-if desired; and in any case the upper Specification of Letters Patent.

edge should be rounded orthe sharp edge removed or covered so as not to .cut e -mouth of. the person drinking. The said tube a is of such a l h or is so constructed that it may be contained in the med1cine bottle d or other receptacle when the stopper or cork e of the bottle is inserted or if applied to a. flask when the cap is closed, but so that when the cork, cap, or the like 1s ren1oved or opened, the upper end of the drlnklng tube a shall project automatically so as to be easily available for drinkmg purposes. The means for causing the drmkmg tube to project above the top of the mouth of the bott e or flask suitably consists of a spring 7 fastened to the tube. As shown in Figs. 1 to 4 the spring f is of the blade type-and in Figs. 1 and 3is secured to the tu e a by a single split ring or clip 9 or by two clips but it is evident that any other suitable form of s ring may be employed.
This spring 'norma y rests on the bottom of the bottle in a flexed condition when the cork,
stopper or cap, c is in the closed position, in which case it presses the tube a down,- but immediately the cork is removed, the spring unflexes and tialusefs thle) tube a to rise bto the osition suita e or ein grasped t e 'ps or theteeth of the er, who then sucks up the liquid.
Thespring may be made of metal, vulcanite, rubber, or other suitable material, and of various sizes, and if not made in one with the drinking tube, is suitably fastened "thereto byelhmping, whippmg, or in any other convenient manner, and preferably, so that it may be put or slid into any desired position on the dr' tube, for the purpose principally of adjusting the length of tube to the size of the bottle, so that the tube rojects sufliciently when the cap or the l' e is removed. This spring 7 is conveniently made curved as seen in Figs. -1 and 2 or corrugated as shown in Fig. 3 so of lower end of the drinking tube a sha be to lie against one side or near one corner or other of the bottle or flask, so as to steady the tube in the. bottle, and there is an added advantage'in using a lateral spring for. bottles with hinged ca s,
inasmuch as then the tube, if put into t e- The spring f may be secured to the tube a.
by means of two split rin or collars g, as shown in Fig. 2, instead 0 one such 'r1ng or collar for the purpose of preventing the spring from being moved out of lme with the tube and for purposes of ad ustment to suit the length of the bottle. Or the drinkin tube a is provided at its lower end with 'a s 1ort length of india" rubber tubing h Fig.
. bottle.whether the drinking tube be in its raised or depressed condition,-whereas if a rigid, tube be provided only with a spring, such as f, Figs. 1, and 2, the said spring raises or tends to raise the lower end of the tube from the bottom of the flask when the ea or the like is removed.
' the modification, as applied to a flask, illustrated in Figs. 5 and 6, the tube a is shown to be held down by the closed cap j in Fig. 4 and to be protruded through the open mouth of the flask by the un-flexlng of the rubber tube It in Fig. 6. The lass and india rubber tubes are made 0 various lengths to suit bottles and flasks of different heights and to some extent the effective lengths of the combined tubes may be regulated by slippinglor working the india rubber tube along t e glass tube, more or, less. The tube a may. be provided with a small annular notch in Figs. 1, 5 and 7 to facilitate the descent of the tube into the flask in the case, of a hinged or so-called bayonet joint cap by the insertion of a finger nail into the sald notch and applying downward pressure in the event 0 t e tube tending to be jammed by the cap when the latter is being opened. If desired and to save india rubber the lower end of the tube It ma be made of lass or other suitable materia so that the india rubber tube only forms a flexible or elastic connection between the two rigid tubes.
According to another modification seen in Fig. 7 the drinking tube is made in two parts, the one part ahaving a piston or packing ring I and being adapted to slide telescopically within the other part m. A hehcal spring a insures the rising of the upper end of the tube part a above the level of the mouth of the flaskwhen the cap or the like is removed. The lower end of the tube part m may be constricted and open as shown or perforated to hold the s ring in place and to enable the liquid to be sucked up. Or the helical spring can be replaced as shown in Fig. 8 by a tube of rubber 0, connected in any suitable manner to both tubes, a and p, the said rubber tube 0 being adapted to collapse. in the direction of its axis when ressure is applied to the top of the tube a ut to resume its normal osltion when such pressure is removed. e bottom of the tube may be closed and perforated asshown,
or it may be open and serrated or otherwise formed or bent so as to insure a free assa e of the liquid in whatever position t e tu e may be when resting on the bottom of the bottle or other receptacle. Or as shown in Fig. 9 the tube a is provided with a fixed or ad ustable collar 9 and a movable skeleton and partially cylindrical frame 1' provided with two collars s and t adapted to slide on the tube which frame also hasan extension at which rests on the bottom of the bottle or flask and the said extension may have a collar 'v. The sprin n is arranged between the collar g and t e collar t of the frame so that when the tube a is pressed downward the spring 01. is compressed and when it is released it causes the tube to be projected above the mouth of the bottle. It is however evident that a drinking tube of this the mouth of the bottle by said member I when the bottle closure is removed.
'2. A drinking tube for a bottle or flask provided with a s ring adapted to be compressed by the cor or closure of the bottle when in the closed osition and to cause the upper end of the tu e to be projected beyond the mouth of the bottle when the closure is removed, substantially as set forth.
3. A drinking tube for a bottle or a flask provided with a spring adapted to be compressed by the cork or closure of the bottle when in the closed position, and means for adjusting the position of the spring relatively to the tube, substantially as set forth.
4. A drinking tube for a bottle or flask, a movable frame at the lower end of said tube and a spring tending to force the tube and the frame apart, substantially as set forth.
5. A drinking tube for a bottle or flask, a movable frame at the lower end of said tube, a spring tending to force the tube and the frame apart and means for adjusting the position of the spring relatively to the tube, substantially as set forth.
6. A drinking tube for a bottle or flask, a skeleton frame adapted to slide on the lower end of said tube, a collar on said tube and a helical spring surrounding said tube and situated between said collar and a art of the saidframe, substantially as set orth.
7. A drinking tube for a bottle or flask, a skeleton frame adapted to slide on the lower end of said tube, a collar adjustable on said tube, and a helical spring surroundin said tube and situated between the adj ustab e collar and apart of the said frame, substantially as set forth.
8. A drinking tube for a bottle or flask, a skeleton frame having two collars or sleeves adapted to slide on said tube, a collar adjustable on said tube and a helical spring surroundin said tube and situated between the adjustable collar and one of the collars on the frame, substantially as set forth.
9. A drinking tube for a bottle or flask, a skeleton frame having two collars or sleeves ada ted to slide on said tube, an extension at t e lower end of said skeleton frame, a collar adjustable on said tube and a helical spring surrounding said tube and situated between the adjustable collar and one of the collars on the frame, substantially as set forth; j
