Abstract of GB138306 138,306. Etablissements Bognier et Burnet. Jan. 29, 1919, [Convention date]- Balls. - A closure or valve for. inflated balls and toy balloons consists of a flanged tubular member b projecting into the interior of the ball and two flat pieces d of elastic material secured to one another along their longitudinal edges e and secured at their upper edges around the tube b. Thus the ball can be inflated through the tube b, and the pieces d act as a check valve to prevent the air from escaping. The ball can be deflated by inserting a rod through the tube b so as to separate the piece d.

Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be performed, we declare that what weclaim.is:- . An inflatable and deflatable body comprising an opening through which it .may beinflated, a tubular member, with an indiarubber flange-,* projecting radially in,to the interior of the body and having its flanged extremity fixed on to the edges of the opening, and a valve of the aorta type comprising two sheets ofindiarabber the longitudinal edges -of which are united, the extremity of-the sleeve so formed embracing the lower end of the tubular part, and the said body being .characterized by the fact that. it does not comprise any rigid piece and that thelowei lips of. the valve are separated when at rest and are adapted to be pressed against one another,by the .pressure. of the inflating air inside the body so as to close the valve.

Improvements in or relating to Toy Balloons, Playing Balls and the like.

EMI1.1

We, ETABLISSEMENTS 130GNI1cR & BURNET, of 21-23, rue des Filles du Calvaire, Paris, in the Republic of France, do hereby declare the nature of this invention and in what manner the same is to be performed, 'to be particularly described and ascertained in and by thefollowing statement:-

The present invention relates to an inflatable and collapsible toy balloon or playing ball which combines several advantageous features of novelty over such articles as hitherto known. These advantages comprise:-(1) There is no projecting tube or other inflating means outside the ball to interfere with the full use thereof as a playing ball, any projecting inflation tube being further objectionable when as in the present invention the balloon or ball is intended to be inflated by blowing from the mouth. (2) The ball requires no great pressure of air from the mouth to inflate it owing to the special, construction of the valve (of the aorta type) which is so formed as to be normally open when not under pressure, and this is an important feature when the ball is to be used by young children. (3) There are no metal or other rigid parts or connections, the ball, air inlet and valve being all formed of rubber and constituting when assembled and cemented an integral whole of rubber, thus avoiding the wear which always occurs where metal or other rigid parts are connected with rubber parts. The ball may be instantly deflated, in the known manner with. valves of this type, by the insertion of a pencil or other small rod into the air entrance to separate the leaves of the valve, so that the ball or balloon may be then folded up and carried in the pocket.

The accompanying drawings illustrate the invention as applied in the case of a playing ball. In these drawings,

Figure 1 shows a section of the upper part of the playing ball, provided with its automatic closure.

Figures 2 and 3 are sectional plans on X, X and Y, Y in Figure 1.

Figure 4 shows the method of deflating the ball.

The wall of the ball, which is generally' made ofindiarubber, isihdicated at a. It comprises at one point an opening b, which takes the closure or valved. This closure is fixed to a tube c which is itself secured to the edges of the opening 1) by any suitable means.

This tube c is made ofindiarubber, and so is the closure, the latter generally consisting of two sheets d, d1 arranged as shown in Figures 1, 2 and 3. It

<Desc/Clms Page number 2>

will be seen that only the edges of these sheets are stuck together on a breadth e, thereby forming in the central part a passage which, starting from an approximately cylindrical form in the neighbourhood of the tube c, (Figure 2), ends in a completely- flattened form towards the other extremity (figure 3).

In this way, if the opening of the' tube c is applied to the mouth,, or to any blowing appliance, air under pressure penetrates directly into the interior of the 'ball. But as soon as theblowing .ceases, . the pressure inside,acting on the sheets-d, d1, immediately causes them toadhere to one another and perfect closure is effected. In this way, the ballcan be utilized as 'long as is desired without becoming even partially ',deflated.

When the p'layer has finished and desires to carry away the ball, all that is necessary is to insert any rod f, as shown in Figure 4, pushing it in far enough to separate the sheets d and d1. The separation of these sheets being effected in this way at their central parts, the air immediately .expands and the ball becomes empty, which enables it to be folded up .in. any suitable manner, so that it can easily be carried-without being in theway. -

It will be seen that this device is very simple, and thus creates an eminently practical article or toy, complying with all the requirements that can be formulated for this type of article. In particular it presents the advantage of not comprising any projecting part, nor any metal part, and this latter feature renders it very light and 'obviates the deterioration that is always caused in course of time onindiarubber by a hard metal.Further, owing to the special construction .of valve it requires no great effort to inflate it.
