TOY

Filed March 25, 1933 INVENTOR fiazzffil Zeekz; BY

Patented Feb. 25, 1936 UNITED STATEE PATENT QFFICE 13 Claims.

The invention relates to a novel toy adapted to float upon the surface of water in a bath tub, basin or other container and to produce interesting effects by use of pneumatic pressure.

The principal object of the present invention is to provide a novel floating toy. One form of the invention comprises essentially a substantially hollow casing adapted to be placed upon the surface of a body of water, the said casing being designed to gradually settle to a predetermined depth into the water while the trapped air within the hollow interior of said casing slowly escapes through a relatively small aperture of the casing while water simultaneously enters the lower portion of the casing for displacing the air, the

escape of said trapped air under pressure being arranged to produce interesting and pleasing effects.

Another object of the present invention lies in the provision of a novel toy of the above character which is so constructed and arranged as to provide a receptacle for holding soapy water or other liquid, through which the escaping air is caused to pass, thereby producing a mass of soap bubbles so disposed as to create a pleasing and interesting effect.

Still another object of the present invention is to provide a novel toy of the above character capable of maintaining itself in an upright and stable position during the settling movement of the toy in the water, said toy being designed to permanently trap a limited quantity of air to thereby limit the depth of immersion of the toy and prevent the complete sinking of the same.

Still another object of the present invention lies in the provision of a novel toy of the above character which is of simple, rugged construction and which possesses great stability in the water in use and of relatively light mass or weight so as to be easily ported and lifted from the water to restart its operation, thereby enabling the same to be used satisfactorily by small children as well as by older persons.

Other objects of this invention, not at this time more particularly enumerated, will be clearly under'stood from the following detailed description of the same.

The invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a vertical sectional view taken through one form of the novel floating toy of the present invention.

Fig. 2 is a sectional view taken along line 2-2 55; of Fig. 1 looking in the direction of the arrows.

Fig. 3 is a view in elevation of a somewhat modified form of the invention.

Fig. 4 is a view' in elevation of another modified form of the invention; and

Fig. 5 is a view in elevation of still another form of the invention.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now to Figs. 1 and 2 of the drawing, wherein one form of the novel toy of the present invention is illustrated, the reference numeral l designates a hollow casing or body forming a diving bell and which is illustrated as of circular cross-section as viewed in plan, the said casing being closed at its top and open at its bottom and being adapted to float upon the surface of a body of water The hollow casing or body I may be made of any suitable material, such as celluloid or other cellulosic products, synthetic resin, sheet metal etc.

The upper portions of a number of supporting members or wires 3 extend upwardly adjacent the interior surface of the lower portion of the casing i, and the upper end portions of the supporting members 3 project outwardly through apertures provided in side walls of casing I and are preferably headed over as at #3, thereby securing the upper ends of these supporting members 3 to the lower portion of the casing I. Four of the supporting members or wires 3 are illustrated in the drawing, although it is to be understood that a greater or lesser number of these members may be used. The supporting members 3 are illustrated as extending downwardly and inwardly of the casing l and have their lower end portions securely embedded in a mass or weight 5 of a preferably heavy metal, such as lead or cast iron or other suitable material.

The weight 5 is illustrated as of circular shape in plan although this weight may have any other desired shape and is positioned so that its vertical axis coincides with the vertical axis of the casing l. The weight 5 is of sufficient mass in the case of the light weight casing illustrated to cause the center of gravity of the complete toy to lie below the center of buoyancy of the same when the toy is placed upon the body of water 2. In other words, the weight 5 is of suificient magnitude and is placed at a sufficient distance below the bottom of casing I so as to hold this casing in an upright position when the same is placed in the water but it is obvious that the casing may be proportioned and designed to maintain itself in an upright floating position even in the absence of the weight 5.

The'top 6 of casing I is illustrated as of substantially dish-shape, the same being formed with 'a central upstanding hollow cylindrical portion I that is open at its bottom so as to communicate with the interior of the casing and 1 is closed at its top. Owing to the dish-shape of the top 6 and to the presence of the cylindrical portion I, there'is provided an annular 1'ecep-- tacle 8 adapted for receiving a limited quantity of soapy water'or other liquid 9. Owing to the V dish-shape of the top 6 and to the presenceof 7 shown resting upon the flat top II of the up-" standing portion I. The boy III is shown as holdthe hollow interior I3 of the figure I II.

the upstanding cylindrical portion l, the liquid 9 is prevented from spilling out of the receptacle 8 even though the casing I be accidentally jarred or tilted considerably in use. Owing to the'approximate V-shaped cross-section of therecep tacle 8, the liquid 9 has a relatively large surface area even though the volume of liquid 9 is relatively small. This is'desirable as the relatively large surface area of liquid 9 gives the impression of a large quantity of liquid which is pleasing and attractive, whereas'the actual small vol -,ume of this liquid prevents the casing I from being top heavy and enables the use of a relatively light weight 5.

The miniature figure or body of a boy I is ing a pipe I2 which extends downwardly into the liquid 9 in receptacle 8, the open mouth of the pipe being positioned below the surface of the liquid 9 in use; The pipe I2 communicates with A vertical tube I4'has its upper portion extending into the figure III, the juncture between pipe I2 and the body I0 being sealed. Tube I4 extends downwardly through a conforming aperture provided .in .the top II of cylindrical portion 1 and. its

lower portion projects into casing I toa point somewhat below the dished top 6. The juncture between the upper portion of tube I4 and the casing I and body III is sealed to prevent the :escape of air from casing I along the exterior of this tube. In use, in order for air to escape from within casing I, it must pass through tube I4 into the hollow interior I3 of the figure or body I0, and from thence outwardly through the pipe An inwardly opening check valve I5 is illus- ,trated as provided adjacent the top of the cylindrical central portion I of the casing top 5. The check valve I5 may be of leather or other suitable material, or the same may be of any suitable type, such as a spring pressed ball and is normally closed, thereby closing the aperture I6 provided in the wall of portion I of cover 6. It is to be understood that check valve I5 may be omitted, if desired. The lower portion of easing I is illustrated as provided with a plurality of angularly spaced slots II which extend upwardly for. 'a distance from the bottom of easing I.

and out through'tube I 4,body ID and pipe I2,

Since the air pressure within casing I is greater closed. Owing to the relative narrow internal than that of the external air, valve I5 remains diameters of tube It and pipe I2, the air can escape from casing I but slowly and produces a stream of air which flows up through the soapy water 9 in receptacle 8, thereby producing a mass of soap bubbles I8 as shown in Fig. 1, cmating a very interesting and pleasing effect. The production of bubbles I8 may continueseveral minutes or even longer before the downward movement of the toy ceases in use.

-As the air within casing I gradually fiows out through pipe I2, the casing I descends lower and lower into the water 2, the air within this casing being displaced by water passing upwardly through the open bottom of this casing. When the casing I has descended sufficiently to cause the lower end of tube It to enter the water within the'cas i'ng. the water acts to close the bottom of this tube It against furtheregress of air,

so' that the remaining air within casing I is trapped therein, thereby serving to prevent further settling of this casing and serving to cause the toy to float indefinitely. After the casing I has reached the lowest point of its downward movement, no more air passes outwardly-through pipe I2 and consequently no additional soap bubbles I8 are formed. 7

In order to continue the production of the soap bubbles lt, the toy is lifted bodily out ofthe water in order to permit a recharging of thecas-j ing with new air either through the open bottom or by the admission of air through the valve controlled opening I6 in those cases where such air opening is used. As soon as the casing I" beginsto move upwardly, the water within the interior of this casing, due to the action of gravity, tends to move downwardly and outwardly thereof, thereby creating a region of reduced pressure within casing I, resulting in the automatic inward or opening movement of valve I5,

thereby uncovering opening I6 and permitting air to enter the interior of easing I. The further casing I is lifted, the more air will enter the same through opening I5 until it again becomes completely filled with air, whereupon the'toy may again be released or placed upon the surface of the water 2 in the event that the toy has been completely lifted out of the water, whereupon the previously described action will be repeated, i. e. air will'be discharged outwardly through pipe I2 while water enters the bottom of casing I.'

The presence of the slots I'I enhances the stability of easing I in the water, since the depending tongue-lilse portions I9 of the casing I,

formed by the presence of slots I'I, act as vanes for engagingthe water to prevent accidental tilting of the casing i. slots Il facilitates the lifting of the casing 'I out of the water since they tend to break up the suction efiect created by the air within the casing I. The slots I? are particularly valuable when the valve I 5 is not used. It is to be understood. however, that these slots may be omitted entirely, if desired. Also, it will'be apparent that instead of 7 using the curved wires or rods 3 for supporting the weight 5, the side walls of casing I may be continued downwardly and inwardly so as to support the weight 5 in wh ch case a suitable aperture or apertures, such as the slots. I! would be provided in the lower portion of the side walls of casing I in order to permit the entrance of water thereinto in use. 7 1

It will be apparent that the small stream of Also, the presence of the air escaping from within the casing of the toy in use, may be employed for other purposes than that illustrated in Fig. 1. For example, in Fig. 3 a casing 2| is shown, which casing is of substantially cylindrical shape having a flat closed top 22 and an open bottom. Wires 23 are illustrated as serving to support a cylindrical weight 24 from the bottom of casing 2|. A small figure ofa turtle 25 is illustrated as attached to the upper surface of top 22 of easing 2|. The turtle 25 has a hollow interior adapted to receive a quantity of liquid, such assoapy water 26.

A bent tube 21 is illustrated as contained with in the hollow interior of the turtle 25. Tube 21 has a relatively long leg 28 extending downwardly through aligned apertures provided in the bottom of turtle 25 and in the top 22 of easing 2|, the lower portion of this leg projecting for a distance into the casing 2|. The lines of juncture between the leg 28 and the edges of the apertures provided in the turtle bottom and in the top 22 for receiving this leg 28 are sealed so as to prevent the escape of air from within casing 2| except through the tube 21. Tube 21 has a short depending leg 29 which projects into the soapy water 26 within the turtle 25. When the casing 2| is placed upon the surface of a body of water, the weight 24 causes the same to settle, thereby compressing the air within casing 2| and forcing the same upwardly through leg 28 and then downwardly through leg 23 of tube 27. This air escapes upwardly through the soapy water 23 thereby creating soap bubbles which pass outwardly through an aperture 30 provided in the neck of the turtle so that the turtle is caused to produce a mass of bubbles |8', creating a very pleasing effect.

When the water within casing 2| reaches the bottom. of leg 28 of tube 27, no more air can escape from within casing 2| and the air remaining therein serves to retain the toy afloat. When it is desired to repeat the operation, it is merely necessary to lift the casing 2| upwardly, thereby causing the water within this casing to descend outwardly thereof and permitting air to enter through the slots I provided in the lower side walls of the casing.

In the form of the invention illustrated in Fig. 4, ihe casing 3| is illustrated as carrying a weight 32 by means of wires or rods 33. A fan or pinwheel 34 is illustrated as turnably mounted upon the casing 3| and is adapted to receive air directly thereupon from a pipe or tube 35 which extends downwardly into the hollow interior of casing 3|. In use, as the casing 3| descends in the water, air trapped within this casing passes outwardly through tube 35 and causes rotation of the fan 34. When the water within the casing 3| reaches the bottom of tube 35, the downward motion of the casing stops and the propeller 34 comes to rest. By again raising the casing 3| so that air may enter through slots H, or through the open bottom of casing 3| in the event that slots I! are not used, the casing may again be released, thereby repeating the operation. The settling motion of the casing may consume several minutes or more, during which time the fan 34 continues to rotate.

In the form of the invention illustrated in Fig. 5, the casing 36 is illustrated as supporting a weight 3? by wires or rods 38. A bird whistle 39, as of the water filled type, is fixed upon the top of casing 33. A tube 40 is connected to the bird whistle 39 and extends downwardly for a distance into the interior of casing 36 so that as this casing descends in use, air passing outwardly through tube 40, will cause the bird 39 to produce musical sounds simulating those of a real bird. As before, when the water within casing 36 reaches the bottom of tube 40, the settling action of casing 36 stops.
