SPECIFICATION forming part of Letters Patent No. 521,773, dated June 19, 1894.

' Application filed September 28, 1893. -ia1N ,486,686i (No model.)

To wZZ-whom" it may concern.-

Be it known that 1, WILLIAM M. DECKER, of Kingston, in the county of Ulster and State of New York, have invented a new and use- .ful Improved Nursing-Bottle, of which the following is a full, clear, and exact description. I

My. invention relates to improvements in bottles or like receptacles, used to contain liquid food that is to be fed to infants, and that are adapted to permit the gradual removal of such food by the child in the act of sucking a mouthpiece that is connected with thebottle.

Nursing devices may be said to involve generally two species: first, those with tubes entering the receptacle or cell, and second those known as gravity devices. In the first species. the receptacle is emptied entirely by suction while in the second the receptacle is emptied by the gravitation of the fluids to the nipple. v

My invention relates especially to the gravity species and has for its object to facilitate the gravitation of the fluid without obstruction, and consists of a cell or receptacle constructed without breast orneck, and closed by an elastic cover constituting an integral breast and nipple, substantially-similar to a mothers breast and nipple. As a result of this construction the receptacle as well as its cover are capable of ready and perfect cleansing, which is an all important consideration in administering artificial food to infants, and another result is the ready flow of the fluids by gravity info the breast and nipple without necessitating the undue elevation of the receptacle and also the avoidance of collapse of the nipple as the result of suction.

A further advantageous result of my invention consists in the fact that the infantis restricted to a natural hold on the nipple and it can only enter the mouth to a limited eX- tent and not so far as to gag orchoke the child, but to a sufficient distance to avoid ingestion of food by restricting its discharge to the tongue and not beyond the tongue and'into the throat as occurs in the use of receptacles which may be forced into the mouth.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a partly sectional side view of the device. Fig. 2 is a side view of the improvem ent taken'opposite the arrow 2 in Fig. 1. Fig. 3 is a detached side view of the top portion of the device. Fig. l'is a plan view of the part shown in Fig. 3. Fig. 5 is aplan view of the receptacle having the cover portion removed. Fig.6 is a side view of the improvement showing the upper part secured upon the lower portion with the improved clamping device; and Fig. 7 is an enlarged detached perspective view of the main por- 6r;

tidn of the clamping device.

The receptacle A, is constructed of glass or other approved material, without breast or neck and substantially rectangular in form, but may be given a cylindrical or elliptical shape, having suitable dimensions for its use,

and for convenience in service vis made of a greater breadth than thickness between parallel side walls, the wider 'part being shown in Fig. 5, as defined. bythe space between the walls a, a, and the lesser dimension indicated by the distance between the parallel walls 17,12. The corners of the receptaclev A are all rounded, so as to avoid sharp angles and thus prevent material from lodging, and it is essential that the dimensions of the receptacle should be such as will permit the free insertion of the fingers of the person who is cleansing the vessel.

The bottom wall of the receptacle A, is flat, and of a sufficient area to afford a reliable base whereon the entire device may be sustained in an upright position on the horizontal surface of a stable support, such as a table or like article.

The open upper end of the receptacle A, exclusive of its ribbed projection, is preferably equal in area to a cross section taken at any point between its upperedge and one near to the curved corners at the bottom wall, and

from said edge a flange or rib c, is outwardly projected which has its lower side formed at a right angle to the body of the receptacle, and is rounded on the upper corner as shown in Figs. 1 and 6, where the receptacle A is shown broken away.

The cover B, for the receptacle A, is normally of a conoidal form as shown in Figs.3 and 4; and consists of measurably thin, elastic material such as vulcanized gum fabric. There is a circumferential rib d of proper thickness formed on the free edge of the cover B, and the relative diameter of the latter is such as will permit its ribbed edge to be stretched over the rib or flangec as indicated in Figs. 1, 2 and 6.

The top portion of the conoidal cover B, is rendered coniform, and slightly contracted in diameter at a proper distance from its apex, thus producing a mouthpiece C of conoidal form which is finely punctured at its upper terminal.

It will be seen that when the conoidal cover B, is stretched over the substantially rectangular ribbed upper end of the receptacle A, its lower portion will be caused to conform thereto by reason of the elastic and contractile nature of the material composing the cover, and the rib d on the latter will be drawn into close contact with the lower side of the flange or rib 0, so as to produce a liquid tight joint between the parts, thus producing a bottle with a colloidal top and a conoidal nipple or mouthpiece on the apex of said top.

As a measure of additional security, the clamping device shown in Figs. 6 and 7, may be utilized to hold the parts A, B, together. This comprises a band or cord 6 and a straining and locking piece E, the latter consisting of a tubular link that is attached by one end to oneend of the clamping band, and has a vibratable bar 9, pivoted near one of its ends within a slot longitudinally formed in said link, the other end of the band beingloosely inserted through the opposite perforated end of the link and secured to the inner end of the bar g, so that the folding of the latter upon the link body will draw upon the cord.

To apply the clamping device to the part B, the latter is drawn far enough below the rib 0 upon the receptacle A, to permit the band a to be located between the ribs 0 and d, in contact with the exterior of the cover B. The length of the band e, should be such as will allow it to slightly bind upon the cover B when in position, and the bar 9 is swung away from the link E, the band being caused to tighten upon the cover and bind it upon the receptacle A when the bar is folded upon said link, which folding movement will lock the bar against accidental displacement, and retain the band in clamped condition until the bar is lifted into the position shown in Fig. 7, and is swung farther toward the end of the cord attached to the link.

By the peculiar construction of the said receptacle A, the interior can be easily cleaned, and the cover B also, as the latter along with the integral nipple C, can be turned inside out, so that all food particles may be washed from its inner side, and thus render the entire device sweet and clean, which is a prime essential for the preservation of health of the child fed from the said receptacle.

As the two parts comprising the improved nursing bottle are easily separated and connected, and the receptacle A is not contracted at its open end, it will be evident that itmay be filled with liquid food without requiring a funnel, as it maybe dipped intoa vessel containing said food, or be filled to a proper height by pouring the latter into it, a graduated scale on one side of the receptacle enabling the operator to determine the proper quantity at sight by filling to a certain point on the scale.

The peculiar shapes of the parts comprising the improved nursing bottle, adapts it to deliver all its contents without obstruction, into the part 0 and thence to the mouth of the user of the device.

Finally, it is claimed for this unique nursing bottle, that it embodies in simple form and an inexpensive construction, a perfect sanitary feeding device for infants, which will obviate disease that results from want of proper assimilation of food, and that will permit a correct administration of food in a perfectly clean condition.

I am aware of course that nursing bottles are not new in which the cell or food receptacle is contracted to form a breast and neck and surmounted and closed by an ordinary elastic nipple, and do not wish to have my invention confounded therewith. The gist of my invention, as before stated, liesin constructing the cell without any breast or neck and closing the open end thereof with a breast and nipple made integral and in form similar to a mothers breast and nipple, so that the entire cover is capable of compression and movement similar to the human breast, all of which results in securing at all times a proper and ready flow from the receptacle and rendering both the receptacle and its cover capable of ready and perfect cleansing.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A nursing device consisting of a cell or receptacle having substantially an uncontracted and open upper portion closed by an elastic breast of dome-shaped form, terminating at its apex in a perforated nipple, substantially as and for the purposes set forth.

2. In a nursing device, the combination, with a receptacle having an uncontracted open upper end and an elastic dome-shaped cover terminating at its apexin a dome-shaped nipple, of a clamping device for the cover consisting of apliable band and a locking bar pivoted in a slot of the link and attached by its inner end to the other end of the band, substantially as described.

3. Asa new article of manufacture a cover for a nursing cell or food receptacle, consisting of an elastic dome-shaped breast open at its base and adapted to embrace the cell, and terminated near its upper portion and made integral with a perforated nipple, substantially as and for the purpose set forth.
