VThis 'invention relates to improvements in vacuumbottles and lts chief Objectis to-*pro- 'vide 'a' vacuumI bottle l provided witlr'clan'up-y ing means whereby acup rmay be removably secured .asa cap orcover tothe top` of the bottle. f

With the lforegoing and other objects iny view `the invention consists in the combination and arrangement ofparts to be hereinafterffully described, pointed out inthe claims and illustrated in the accompanying drawing which forms a part ot this applica Y tion for patent and in'whichw Fig. 1 is a fragmentary view of a vacuum bottle constructed accordingto the present invention and provided with a cup.

- Fig. 2 is a vertical sectional view taken on line 2-2 of Fig; 1.

Fig. 3 is aplan view of Fig. 2 with the cup in an alteredposition. l

Fig. 4 is an enlarged fragmentary view of Fig. 3 illustrating the clamp lever employed.

Like reference characters denote corresponding parts throughout the several views.

The present vacuum bottle is so -constructed that it may releasably carry a porcelain cup which when secured to the bottle serves as a cap therefor and when detached serves as a y drinking cup. It is recognized that the porce* lain cup has many advantages over metal cups, paper cups and the like as it is a poor conductor of heat, it is easy to clean and keep clean and is therefore sanitary andconvenient e 1n use.

The present invention provides a vacuum bottle having a resilient collar-adapted to releasably lgrip the mouthk of the porcelain cup when the cup is inverted, and a handlereceiving bracket for the cup handle that cooperates to hold the cup in position as a bottle cap.

The envelope 1 of the vacuum bottle is formed with anintegral collar 2 that is spaced away from the neck 3 of the bottle to form a channel 4 that extends from a straight shoulder 5 around thebottle. The said collar 2 forms one Wall, the outer Wall, of the channel 4 for approximatelyone-half the circumference of the bottle or to a point diametricallyopposite the shoulder 5 and from this point 6 the collar 2 is separate Vfrom the envelope 1 as clearly shown in Fig. 3.

That part of the collar 2 between the shoulder 5 and the point 6 is substantially narrower than that'portion between the point 6 and the loose end of thek collar, the collar reas, "serieu Noi 275,936(

collar 2 isl the bracket 8 that'is connected by the locking lever 9 tov the link 10 vthat is car-k ried by the bracket 11 carried by the free end ofthe collar 2. yThe locking lever is somewhat on the order of a toggle lever and when g its free outer end, forming a linger piece, is moved toward the bracket `111it loosens the connections between the brackets 8, 11, as shown in-F ig. 3, thus permitting one portion of the `collar 2 to move away from the envelope 1. Whenthe lever 9 is moved toward angel against the bracket 8 the bracket connections are stretched and thel movable port1on of the vcollar 2 moved into frictional engagement with the envelope and with the iiXed end of the collar 2. A .i

To the collar y2 at the point 6 a handle bracket 12 is secured. Itis of the general outline and shape, though slightly larger, than the handle 13 of the porcelain cup 14 whichit 1s adapted to receive releasably and to house as shown in Fig. 1, said handlek bracket beingl formed with a vertical stop bar 15 which prevents movement laterally or outwardly of the that the mouth of the cup is received in the channel 4.

1. In a vacuum bottle, an envelope formedv with a channel at its junction with the bottle neck, a collar integral with said 'envelope butl l vThe c up is now oscillated in the said cliannel until thehandle 13 is moved into the The lever 9 is now moved det-ached therefrom throughout a portion of its length, a locking lever connecting the endsV of said collar whereby the detached end may be releasably clamped against the attached end of saidmember, and a cup handle bracket l carried by said collar.

2. In a vacuum bottle, an envelope Aformed with a channel at its junction with the `bottle neck, a collar integral with said envelope but detached therefromthroughout a portion of its length, said `cellar in ene positirm, forming one will o' said d annel, a lookin lever connectintgr the ends of said collar W ereby the detached end may be releasably clamped u against the attached end theredf, and a cup handle bracket carried by said collar.

3. In a vacuum bottle, an envelope formed with aI cup receiving channel atits junction with the bottle neck, a collarintegral with said envelope `but detached therefrom throughout a portion of its length, a lock-'mg lever for said collar, a handle bracket `carried by said col-lar7 and a stop bar for said handle bracket. e

In testimony that l claim .the foregoing as my `own .I have hereto ailixed my signature.
