NURSING oTTLEt Patented Feb. 8, 1887.
UNITED STATES PATENT CHARLES BRACKETT WHEELOCK, OF BOSTON, MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 357,439, dated February 8,' 1887.
Application tiled July 19, 1886.
To @ZZ whom it may concern.-
Be it known that I, CHARLEs BRACKETT VHEELOOK, of Boston, in the county of Suffolk, of the Commonwealth of Massachusetts, haveinvented a new and useful Improvement in Nursing-Bottles; and I do hereby declare the same to be described in the following specification and represented in the accompa.` nying drawings, of which- Figure l is a side view, Fig. 2 an edge View, Fig. 3 a longitudinal and median section, and Figs. 4 and 5 transverse sections, of a nursingbottle provided with my invention, the nature of which is defined in the claim hereinafter' presented. The plane of section of Fig. 4: is directlythrough the air-duct and its elastic covering'ring, the plane ot' section of Figr being through the middle of the bottle.
The bottle shown at A is ilat on one, or its lower, side, as shown at a, its neck b inclining upward from such side to a level with or senlewhat above the other or upper side, as represented.
Within the bottle, and extending wholly or partially around it, close to its closed end, is a groove, c, to receive a flat elastic ring, B, which is to slip on or off a curved projection or air-induction projection, C, arranged on and extending from the bottlcin range with the groove, as shown in Figs. l and 2. An air induct or hole, d, is made in suoli projection at its center, and opens into theliquid-holding space of the bottle.
On the bottle being deposited on a table or flat surface the fiat side a is to be in contact therewith, in which case the nose of the bottle will extend upward,so as to prevent any liquid in the bottle from escaping through the nose.
When the bottle is in use by an infant, an
artificial nipple is to be appliedto it, asnsual with such bottles. While the elastic ring is across the air-induct the latter will be stopped, so as to prevent leakage through it from the bottle; but while the bottle is in use the ring is to be off the projection, to allow air to pass Serial No. 208.367. (No model.)
into the bottle and thereby enable the infant using it to extract the milk `or liquid from` it a to` advantage.
I do not claim, broadly,a nursing-bottle having one side flat, a nose arranged inclined thereto and to extend upward therefrom above the other side, and to the latter side a vent at the. base of the nose; nor do I claim a nursing-bottle having a vent either in one side of its nose or in that ofthe stopper' of such vent; nor do I claim a nursing-bottle having in one side an opening and a depression to receive a thermometer, and also having a shield and a rubber band to hold such thermometer in place, the whole being to allow liquid in the bottle to be in contact with the bulb of the thermometer. y
I am aware that a nursing-bottle has been devised with a continuous groove in its neck, with a hole therein, and that a rubber ring with a hole in it has been sprunginto said groove, so that when the two holes register air may enter the bottle. I am also aware that a boatshaped nursing-bottle flat on one side and having the teat or nozzle end projecting upward therefrom and a valve in the upper side is old. In my device the groove c gradually runs out on each side of the projection C, there being no groove in said projection. The ring B is also without a hole, and is slipped on or off, as occasion requires, and thc smooth grooveless projection permits this.
A nursing-bottle having at its bottom the projectionC, with hole cl and the groove c running out at each side ofthe projection, the latter being grooveless, in combination with a rubber band sprung into said groove and over said projection, as set forth.
