BALLOON INFLTOR WITH ROTATABLE VALVE NOZZLE Filed May 5, 1965 INVENTOR ZPO/n Marzi/70 BY I ATRNE 5.
United States Patent O 3,368,302 BALLON INFLATOR WITH ROTATABLE VALVED NUZZLE Dom Martino, 2 Lawrence Drive, White Plains, N.Y. 10603 Filed May 5, 1965, Ser. No. 453,267 4 Claims. (Cl. 46-90) ABSTRACT GF THE DISCLOSURE Apparatus for inflating toy balloons including a source of air supply, under pressure. A casting joins the outlet of the source to the inlet of the balloon. The casting has a stern connected to the outlet with means therein for releasing a supply of air from the source. Another stem on the casting is connected to the inlet of the balloon, the latter stern supporting a nozzle which is connected to the inlet of the balloon. A valve in the nozzle controls the ow of air into the balloon.
This invention relates to apparatus for inating inflatable devices such as toy balloons and the like.
At childrens parties, the children are often given inflated toy balloons and when there are a large number of children present, the ination of these balloons presents quite a problem. With this in mind, a principal object of the present invention is to provide an apparatus for readily and conveniently inating toy balloons of Various sizes with plain air or with a lighter-than-air gas mixture.
A specific object of the invention is to provide apparatus for inating a toy balloon including a conical nozzle adapted to be temporarily inserted into the iluid intake member of the ,balloon in such a manner as to form a fluid-tight connection therewith during the time the balloon is being inilated.
Another object of the invention is to provide apparatus of this kind that is simple in construction and economical to manufacture.
For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:

Referring now more in detail to the various views of the drawing, in FIG. l there is shown a balloon inflator indicated generally at 10 in the act of blowing up a toy balloon 12. The balloon is made of thin stretchable elastic material such as rubber and has an inlet neck portion 13. The apparatus includes a pressurized container 14 con- 3,368,302 Patented F elo. 13, 1968 ICC taining plain compressed air or a lighter-than-air mixture. The container is cylindrical, of suitable metal, and may be 4" to 8 in height and approximately 3 in diameter. These dimensions will determine the number of average size balloons, usually 8 in diameter, which may be inflated therefrom, for use primarily in household family parties. The container has a metal lid or cover 18 with a central opening 20 therein.
A metal casting in the form of an upright hollow cylindrical stem 22 and an integral laterally extending hollow cylindrical stem 24 is seated on the lid or cover 18 around the opening 20. The stems are approximately 3/s in diameter. The upright stem 22 is open at the bottom with an annular bead 26 therearound. The top of the stem 22 is closed with an opening 28 in the center thereof. A plunger in the form of a round rod 25 extends through the central opening 28 and through the interior of the stem and through the opening 20 in the lid 18 into the interior of the container 14 where the bottom end is connected to a ilexible plastic disc valve 27.
An actuating cap 29 is fixed on the exterior top end of the rod. The lateral stem 24 communicates with the interior of the stem 22 midway the ends of the stem 22 and is closed at its outer end as indicated at 30. An opening 32 is formed in stemI 24 adjacent the closed end 30, and closely spaced inwardly from the opening 32 an annular discshaped ange 34 is formed, which flange is formed with a hole 36.
A conical shaped nozzle 40 of exible plastic material is rotatably mounted on the stem 24 remote from its outer end. The nozzle has a conical shaped body 42 open at its front narrow end and closed at its wide inner end by a flexible diaphragm 44 formed integrally with the body 42 and having a central opening with a neck portion 46 sleeved around the stem 24 and in contact with the ilange 34 and sealing the interior of the body of the nozzle. The wide end of the body is approximately 1%" in diameter.
A valve device is carried by the nozzle 40 and turns with the nozzle around the stem 24. The valve device has an elongated tubular tapered body 52 of metal with a bead 54 around its narrow end, which bead seats in an annular groove 56 formed in the interior surface of the narrow end of the nozzle 40.
The wide end of the tubular body S2 is closed by a circular plate 58 formed integrally with the top half of the body of the tubular body. Plate 58 is formed with a keyhole slot 59. The bottom half of the tubular body tapers downwardly and inwardly on both sides as indicated at 60, both sides terminating short of the bottom dening a slotted portion 62 in the bottom of the tubular body. The bottom edges of the sides are slightly enlarged as indicated at 64 and grip the sides of the stem 24, as best seen in FIG. 7. A bearing member in the form of a circular plate 68 and curved extension 70 leading from the top peripheral edge of the plate toward the end plate 58 is supported on the inner surfaces of the tapered sides 60. The closed end 30 of the stern bears against the circular plate 68 and the extension 70 thereof, as seen in FIG. 4.
In operation, when it is desired to iniiate the balloon 12, the nozzle 40 is turned to the position shown in FIG. 4 wherein the top half of the keyhole slot 59 is contacting the solid portion of the ange 34 on the stem 24. The plunger 25 is pressed down by the finger of the operator on the cap 28 forcing the sealing .disc 27 away from the top of the container 14 permitting the air to escape therearound and out through the stems 22 and 24, through the opening 32 in the stem 24 in the direction of the arrows in FIG. 4, through the tubular body of the valve member, and through the inlet neck 13 of the balloon 12 into the interior of the body of the balloon whereby the balloon is intlated.
In order to deflate the nozzle 40, the valve member 50 is turned to the position shown in FIG. wherein the top half of the keyhold slot 59 is registering with the hole 36 in the llange 34 of the steml 24. In this position of the parts, the compressed air passing through the stem 24 passes through the opening 32 therein into the nozzle 40, through the hole 36 in the ange 34 and through the top half of the keyhold slot 59 into the tubular body of the valve device and out through the narrow end thereof into the balloon 12.
In order to inflate the nozzle 40, the valve member 50 is turned to the position shown in FIG. 6 wherein the top half of the keyhold slot 59 is in contact with a solid portion of the llange 34 on the stem 24 so that the compressed air passing through the stem 24 and out through the opening 32 therein passes into the interior of the nozzle 40 thereby inllating the same.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as delined in the appended claims.
