Specification of Letters Patent. v

To all 'u'hom 1' t may concern..-

Be it known that 1, CHARLES \l". Lannnr,

- citizen of the United States of .-\merica,'re'- siding at Ingram, in the county of .\lle-. gheny and State of Pennsylvania, have invented certain new and useful Improvements in Xipple Covers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to nipple covers and relates more particularly to an improvement.

tle. Fig. 2 IS a verticalse'cti'diial view 6% the same. l lgyfilde elevation of the upon the invention disclosed in my Patent- 9T6,8S7, granted November 29th, 1910.

Besides having the same objects in view as disclosed in my prior patent, the present invention aims to provide a normally closed nipple cover that is reinforced to strengthen and add rigidity thereto, whereby the cover can be repeatedly used without any danger of the same tearing or cracking.

A further object of this invention is to provide a nipple cover that conforms more to the requirements of a regulation nursing bottle, the cover having-a gripping portion that provides sufficient clearance for the bottle rim and the lower'end of a nipplemounted upon the rim.

With these and such other objects in view as may hereinafter appear. the invention resides in the novel construction to behereins after specifically described and then claimed. "Reference. will now be had to the drawing wherein there is illustrated the preferred embodiments of the invention, though it is to be understood that the structural elements are susceptible to.such changes and variations as fall within the scope of the appended claims.

In tho drawing:l igure 1 is a sideelevation of the nipple cover as applied t o g cover, partly b (en away and partly in section, showi g the cover in an open position. Fig. 4 is a plan of the cover, and Fig. 5 is a side elevation of a modifiedtorm of the cover.

A nipple cover in accordance with this invention comprises a hollow spheroidal body 1 conforminginore to an oblate spheroid,

said body having the lower edges thereof provided with an annular head 2 adding rigidity to the lower part of the body and providing a resilient grippingmember that is adapted to grip the net-k3 of a bottle 4 below the rim o of said neck. Formed in-' tegral with the upperedge of the body 1, are semi-cylindrical or semi-dome shaped cover sections 6 adapted to inclose ,the outer portion of a nipple 7 mounted upon the rim 5 of the sections 6 are provided with reinforcements or beads 8 having the ends thereof joined, as at 9 and integral with'an annular reinforcement or bead 10 arranged circumterentially of the body 1, intermediate the upper and lower edges of said bod The cover sections 6, interrne iate the heads 8. have theouter sides thereofprovided with vertical reinforcements b r beads 11, the upper ends of the beads gradually merging into the top of the sections and the lower ends of the beads terminatin at. the upper edge of the body 1. The a vantage of this construction is that the sections v6 tion. said beads restoring the cover' sections to their normal position after having been opened due to the beads 11 being jplaoed under. greater tension than the beads 8, as best that the beads 11 are almost doubled upon themselves while the beads 8 retain more of their natural configuration.

in Fig. 5 of the drawing there is illustrated a modification otthe invention,

with diametrically opposed horizontal slits 13 having the outer edges thereof surrounded by beads H. The confrontin edges of the. cover sections 15 end at the sTits l3 and in consequence of thisconstruction the cover sections 15 can be swung open and farther apart than the sections 6.

construction shown in Figs. ,1 to 4 inclusively'provides a greater degree of stifi' ness in the nipple cover, a more durable construction and a higher degree of efficiency than obtained by the cover illustrated and described in my prior patent.

\Vhat- I claim 1. A nipple cover for nursing bottles, c-omprising an oblate spheroid-shaped hollow body for engagement overthe neck-of a botdome-shaped cover sectionscarried by the upper edge of said body, a bead arranged circumferentially of said body intermediate the upper and lower edges of the body, and

are normally maintained in a vertical poshby spreading. This is principally wherein the body 1 of the cover is provided -of abottle neck 3. The confronting edges shown in Fig. 3, where it will be observed tle having'a nipple mounted thereom semi having a nipple mounted thereon, a bead of the body, cover sections carried by the beads carried by the sections at the confront ing edges thereof said beads terminating at thecircumferential bead of said body.

2. A nipple cover for nnrsi 0 bottles, comprising a hollow oblate spliero id-shaped body for engagement over the neck of 'a bottle the confronting edges of said sections and terminating at the circumferential bead of the body, and vertical beads carried by 15 each section intermediate the vertical edges thereof. In testimony whereof I a'fiix my signature in the presence of two Witnesses.


carried by the lower edge of the body, a I head arranged circumferentially of said body intermediate the upper and lower edges \Vitnesses-z i MAX H. Snonovrrz,

upper edge of said body, beads carried by 3 \CHRIS'IINA T. Hoou.
