ORWELL H. NEEDHAM. Irriprovevenf `in` Combined Breast Pumps and Nursing Bottles.

Paented Sep.. 19,1871.

UNICIED STATES ATENT lingo-i4 FFIC ORWELL NEEDHAM, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 119,044, dated September 19, 1871.

To all whom it may concern:

provement, and Fig. 2 a similarview of a nursing-bottle.

Similar letters of reference indicate corresponding parts in both figures.

My invention consists in a novel construction of a milking shield-attachment to a bottle or milk-receptacle, whereby, when applied to or made to form part of a breast-pump, an easy and natural action on the breast is obtained, and the milk is prevented from passing through the valve or valves into the operatingportions of the pump, and the breast-pump, as a whole, is made readily convertible into a :nursing or feed-bottle.

Referring to the accompanying drawing, A represents a bottle or milk-receptacle designed to stand vertically with its mouth uppermost, and incased or protected by a screw-socket, b. B is a milking-shield attachment, constructed of a nipple-piece or shield proper, which is made up of a rigid `or stiff ring, d, of metal or other suitable material, united 1|by a flexible lining, e, which may be of thin India rubber, to a metal or other suitable tube, f. This connection is such that the receiving-end of said tube lies in, more or less, close proximity to the inner face of the ring or band d, so that not only is air admitted at various points around the shield between the tube and ring to press externally upon the lining to `produce a lateral .compression of the latter on the nipple, but the two parts d and f are free to be rocked or moved about transversely and otherwise independently of one another, to prevent any unsteady hold of the pump or movement of the female from giving pain or interfering with the action of the pump.` Said connection of the parts d and f may be made bythe lining e being stretched over the outer end of the ring df and adjacent outer end or portion of Lthe tube f. The tube f is closed at its back end,

where, however, there may be provided an airhole, g, which is closed by the thumb or otherwise when the pump is being worked, but is uncovered to admit air when it is desired-to effect and ease the withdrawal of the pump from the breast. Said tube j' is, furthermore, provided with an upper lateral branch or nozzle, h, and lower lateral branch or nozzle t', the latter iitting the screw-socket b of the bottle A, and the upper one, h, serving to receive the suction-tube 7c and its valvular attachment m, which pertains to the operating portion of the pump, that may either be of a flexible bulb, bellows, or piston construction, a bulb form of exhauster, however, as shown in the drawing, being preferred.

The air, it will be seen, is exhausted from the receiver or bottle A in an opposite vertical direction, or thereabout, from the iiow of the'milk into said receiver, thereby preventing the valves of the air-pump or exhauster from becoming clogged by the passage of milk through them into the exhauster, and which rst impairs the action of the valves and subsequently ruins the whole apparatus. This liability to derangement is a colnmon one in a well-known globular form of receiver provided with an upwardly-curved tube for conveying the milk from the nipple by reason of the accidental or ignorant inversion of said receiver. The form of receiver here adopted prevents all possibility of such an occurrence.

Furthermore, the receiver A being in the form of a nursing or feed-bottle it is readily converted to such use by simply unscrewing or detaching the milking-shield attachment B with its pump attachments from the bottle A, and fitting over the socket b a cap or stopper, C, carrying a dip-tube, n, suction-tube r, and attached mouthpiece s.

Thus am` I enabled to combine in a simple, practicable, and eflicient manner a breast-pump and nursing-bottle for quick and ready use, as required. This convertibility or combination of two articles, as it were, in one instrument will not only commend itself to the public on the "score of economy, but also of convenience, inasmuch as when the one article is used the other 'is a necessity, generally speaking.

What is here claimed, and desired to be secured by Letters Patent, is-

l. The combination, with the nursing or feed bottle A, of a milking-shield attachment, B, proed of a nipple-ring or band, d, a tube, j, a con-Y vided with an upper nozzle, hf, :1nd a lower noznecting yielding lining, e, and the upper and zle, i, both at right angles to the line of direction lower lateral nozzles h 1l, Which are claimed above, of the shield attachment for coupling to a lnilkessentially as described.

receptacle a device for exhausting the air, sub A ORWELL H. NEEDHAM. stantially as and for the purposes herein set Witnesses: forth. HENRY T. BROWN,

2. The milking-shield attachment B, construct- FRED. HAYNE s.
