Reissued Aug. 20, 1940 UNITED STATES PATENT OFFICE rial No. 756,613, December 8, 1934. for reissue November 15, 1935,
This invention relates to improvements in dolls, the subject matter herein-disclosed being a continuation in part of my co-pending application, Serial Number 658,473, nled February 5 25 1933 (now matured into Patent No. 2,007,784,
granted July 9, 1935).
An object of the invention is to provide a doll of simple and practical construction wherein the hollow body thereof is made compressible to control the ingress of a liquid into the same from a nursing bottle and an outlet provided in said body to permit of the slow egress of said liquid into a cloth or diaper, to thereby simulate human functions. v
The above and other objects will appear more clearly from the following detailed description, when taken in connection with the accompanying drawing which illustrates preferred embodiments of the inventive idea.
In the drawing:
Figure 1 is a longitudinal section through the doll constructed in accordance with the invention.
Figure 2 is a horizontal section through the dolls head.
Figure 3 is an enlarged sectional view through an outlet valve in the doll body.
Figure 4 is a similar view of another form of outlet valve.
Figure 5 is a longitudinal section through an inlet valve which controls the now of a liquid into the doll body, and
Figures 6 and 7 are sectional views of different forms of nipples to be used on a nursing bottle and which cooperate with the valve of Figure 5 in, controlling the ilow of liquid into the doll body.
The doll illustrated in Figure 1 comprises a body I0, arms II, and legs I2 all of which are 110 hollow and preferably made of rubber, the connections of the limbs to the body, fully described and claimed in the above-identified application,
rendering the parts air and liquid tight. The
body I is adapted to`be compressed and then allowed to expand so as to create a suction therein which will be sufficient to draw a liquid from a nursing bottle into the body. As shown in Figure 1, the interior of the body is provided with a partition I3 which forms a liquid receiving compartment I4 in the lower portion of said body. The head I of the doll may be made of any suitable material and is provided with an opening for receiving the neck portion of the body I0. The latter is closed at its neck end by a neckpiece. I6 which may be also made Application Serial No.
of rubber andwhieh snugly ts Within said neck portion so as to constitute a partition between the interior of the body and the head of the doll. The exterior surface of the neckpiece I6 is provided with circumferential beads II over which ts the rubber neck portion of the body, thereby assisting in holding said piece in position and further rendering the body liquid tight. To attach the head I5 to the body I0 there is provided a connecting member I8 one end of which is secured to the yhead while the other end is joined to the neck-piece I6.
The mechanism which enables the doll to simulate the human function of drinking from a nursing bottle, comprises a mouth-piece I9 of rubber suitably mounted within the head I5 by means of a strip having its ends embedded 1n the sides of said head so as to properly position said mouth-piece contiguous to the mouth opening 2|. -The mouth-piece I9 is provided with' an opening 22 adapted to receive the end of the nipple 23 mounted in the neck of the nursing bottle 24, and said opening communicates with one end of a flexible tubing 25 the other end of which is tted over a valve body 26 mounted in a suitable opening formed in the neck-piece I6 to lone side thereof. To the inner end of the valve body 26 is joined one end of a exible tubing 21 the other end of which is extended through the partition I3 so as to communicate with the compartment I4. The valve body 26 has a 10ngitudinal duct 28 extending therethrough and the flow of liquid through said duct is controlled by a ball valve 29 in the end of the body 2lii adjacent the tubing 25. The valve 29 is retained in the valve body by crimping the latter and said valve has a slight movement in the recess thus formed for it but never acts to fully close the duct 28 in any position of the valve, the crimped p portion of the valve body merely acting to retain the valve therein, and not forming a seat for the latter which would be entirely closed when said valve is forced outwardly toward said crimped portion by the exhaust of air from the compartment I4 as the doll body is being compressed. When resting upon its seat, said valve only partially closes the duct 28 due to a small notch 29' formed in said seat, thus permitting a slow flow of liquid from the bottle 24 into the tubing 21 when suction is created within the body by its expansion, after compression.v As air is expelled from the body through the duct 28 and past the valve 29 during compression of the compartment I4, the valve 29 is raised off its seat by the pressure of said air which is then allowed to escape through the mouth-piece I9.
An outlet is provided in the lower back portion of the body l0 which communicates with the compartment |4 that receives liquid from the tubing 21, and said outlet permits the slow escape of the liquid from said compartment into a diaper or cloth (not shown) upon completion of the expansion of said compartment and resulting cessation of the suction which draws liquidinto the cornpartment from the bottle 24. In Figure 3, the structure of said outlet is shown as comprising internally and externally screw threaded members 3U and 3| disposed, respectively, on the inner and outer sides of the body which is clamped therebetween the shank of the member 3| extending through an opening 32 formed in the wall of said body. In the member 3| there is threadedan apertured valve seat 33, the opening therein being controlled by a small ball valve 34 disposed within a cavity and adapted to only partially close said opening in the seat 33 so as to permit of the slow egress of the liquid from the compartment I4. When the body I0 is expanding after being compressed, and the suction created by this operation is having the desired effect of` drawing liquid into the body from the nursing bottle 24, the ball valve 34 is drawn inwardly, by said suction, and tightly against the inner end of the cavity 35 so that air will not enter the body during the suction operation. As soon, however, as
the suction ceases, the valve 34 assumes the position shown in the drawing and thus allows the liquid now in the compartment |4 to ow slowly throughthe opening in the seat 33. This flow of the liquid may be controlled to some extent by adjusting: the seat 33 in the member 3|. When in the last-named position, the valve 34 also permits a slight amount of air to escape from the compartment I4, in addition to that exhausting past the valve 29, when said compartment is being compressed.
The valve structure of Figure 4 accomplishes the same function as that of Figure 3 and comprises a body 36 made of rubber and provided with a circumferentialy groove 31 which receives the portion of the wall of the body surrounding the opening 38 therein so that sections of the valve body 36 will be disposed on opposite sides of said wall and snugly engage the same to prevent leakage from the compartment I4, except through the opening or passage 36 in said body 36. Again, a ball valve 4U within said passage and engageable with a seat 4| therein, controls the slow egress of liquid from the doll body and prevents air entering the latter during suction by being drawn against the inner enclof the passage 39. When said suction ceases the valve 40 falls by gravity against the seat 4| but does not entirely close the passage in this position so that the liquid from the compartment will flow slowly therefrom.
Figure 6 illustrates a form of nipple which may be used on the nursing bottle and is shown as comprising a body portion 42, preferably of rubber adapted to fit over the neck of said bottle and provided with a central liquid passage 43 extending therethrough. Offset from said passage, the body 42 is also provided with an air vent or passage 44 enlarged at its intermediate portion to form a chamber 45 in which a valve 46 has a limited movement. When in the position shown in Figure 6, the valve is seated against the inner end of` the chamber but does not completely close the air vent due to the very small notch 41 formed at said end; but with the nipple inverted, as when in use, said valve seats against and closes the outer rounded end of said chamber, except when it is drawn away therefrom as will presently appear. After compression of the body l0 to expel the air therefrom, the outer reduced end of the nipple is inserted into the mouth-piece I9 in substantially the position shown in Figure 1. The body I0 is then released so that suction may start, whereupon liquid will begin to flow from the bottle into the body, with the valve 46 seated against the outer, or the then lower, end of the chamber 45, shutting off entry of air through the passage 44 into the bottle. As the level of the liquid in the bottle recedes, a partial vacuum begins to form above said liquid and when this partial vacuum becomes suflicient,`it will lift the valve 46 against the then upper end of the chamber 45 and allow air to pass around the valve and through the notch 41 into the bottle, forming in the liquid therein a series of bubbles simulating those formed in a nursing bottle when an infant occasionally releases the nipple to allow air to enter the bottle. When suflicient air has entered the bottle to break the partial vacuum therein, the valve restores to its seat against the lower end of the chamber 45 and the entry of air is again shut off. In this manner, there is accomplished the alternate and intermittent now of liquid from the bottle and entry of air thereinto to simulate the human function of an infant nursing from a bottle.
In Figure 7, the nipple body 48 is provided with an air vent 49 of graduated cross sectional areas anda central liquid passage 50 having a chamber 5| therein in which is movable the ball valve 52. When suction is applied to the nipple in its inverted position, the valve rests against the outer or lower seat of the chamber 5| and thus allows only a restricted or slow passage of liquid around the valve and through the small notch 53 in said seat.
