WATER-BOTTLE STOPPERV SPECIFICATION forming part of Letters Patent No. 693,436, dated February 18, 1902. Application filed October 10, 1901 Serial No. 78,220. (No model.) i I TofaZZ whom it mag/concern.-

Be it known that 1,.(WALTER H. PERKINS,

(assignor to the WATERBURY MANUFACTUR- Water-Bottle Stoppers; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a f ull, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in- Figure 1, a view inside elevation o'f-a waterbottle stopper constructed in accordance with my invention; Fig; 2, a view thereof .in vertical section; Fig. 3, a detached view, inside elevation, of one form which the disk may assume; Figs. 4,5, and 6, corresponding views of modified forms which the disk may assume. My invention relates to an improvement in water-bottle stoppers, the object being to produce at a low cost for manufacture a sim ple, compact, convenient, and effective device constructed with particular reference to ease In carrying out my invention as herein shown I employ a struck-up sheet-metalcap having a flat top 2, a knurled edge 3, and an inwardly-turned flange 4, which issecured to an outwardly-turned flange 5, formed at the upper end of the cylindrical sheet-metal body 6 of the stopper, the said body having threads rolled into it. The flanges 4 and 5 are secured together by soldering or otherwise, or the cap and body may be formed of a single piece of sheet metal. The lower end of the body 6 is turned inwardly to form an annular flange 7, which is entered into an annular groove 8, formed in the edge of the rubber disk 9, which practically corresponds in diameter to the diameter of thesaid body. When the rubber disk 9 has its annular groove 8 entered by the annular flange 7, the disk maybe said to be WALTER H. PERKINS, or WATERBURY, CONNECTICUT, ASSIGNOR TO THE partly within and partly without the body 6.

.It is very firmly secured in place and has a wide-bearing against the outer face of the flange to resist pressure tending to force it into the body of the stopper.

fled forms of the disk; but all of them are alike in having an annular groove to receive an annular flange formed at the lower end of the body, though the portions of the disk separated by the groove, are widely difierentiated in size, whereas the portions of the disk -9 separated by the groove 8 practically correspond to each other in diameter.

In view of the'modifications suggested. and

have it understood that'I do not limit myself to the exact construction described, but hold myself at liberty to make such alterations as fall within the scope and spirit of my invention. v

Having fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a water-bottle stopper, the combi naw tion with a threaded sheet-metal body formed at its upper end with an outwardly-turned annular flange, and at itslower end with an inwardly-turned annularflange, of a hollow sheet-metal cap larger in diameter than the diameter of the said body,'-formed with a knurled edge and formed at itslower, end with an inwardly-turned annularflange which is secured to the. said outwardly-turned annular flange at the upper end of the'said body I which enters the said hollow cap. for the fastoning of the two said flanges together, and

end of the said body and formed in its edge the edge of the inwardly-turnedannular flange located at the lower end of the said with an annular groove for the reception of 9 adisk adapted to partially enter into the lower I r entered into the lower end of the said body In testimony whereof I have signed this and formed in its edge with an annular groove specification in the presence of two subscribfor the reception of the said flange by which it is retained in place, and a cap applied to ing witnesses.
