Description

AQUATIC TOY March 7, 1950 Filed April 50, 1948 JNVE 'OR. Mar/r 808.9

Patented Mar. 7, 1950 UNITED STATES 1 filaim.

My present invention relates to an improved aquatic toy and more particularly to a toy or amusement device comprising a closed or substantially closed tube containing a fluid subject to inherent expansion and contraction there being supported by the fluid a doll or other figure which under action of the expansion of the fluid will rise or fall within the tube, and when the action of the doll is of suflicient speed, the doll will appear to be dancing.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.

In the drawings:

Figure 1 is a front elevational view of the toy of my invention.

Figure 2 is a vertical sectional view thereof.

In this preferred form of the invention shown in the drawings I employ an elongated integral cylindrical and tubular toy of glass, plastic, or other transparent material.

The upper part of the tubular structure is fashioned as a tube 2; the upper and lower ends of the structure terminate in hemi-spherical walls 4, 4; and between the tube 2 and the lower rounded wall it an integral body portion 6 is provided to form the bottom of the tube 2. The body portion is fashioned with a central passage or bore 3, of restricted diameter that affords communication between the upper tube 2 and a lower spherical chamber it that is formed between the lower concave end of the body portion and the lower hemi-spherical wall 4 of the toy. The chamber ill, the interior of the tube 2, and the communicating bore or passage 3, are thus sealed by means of the two rounded end walls 4, 4, of the toy.

I propose to partially fill the tube passage and the lower chamber with a fluid l2 such as alcohol or mercury which is readily responsive to heat changes to expand or contract and the column of fluid in the passage supports a rod [4 which has mounted upon the upper end thereof a figurine or 2 doll iii. The exterior of the tube is coated with an opaque material 58 up to the line it intermediate of the upper half of the tube.

It will follow from the utilization of the structure according to the above description that when the user of the toy applies his hand to the lower end of the tube about the spherical chamber of fluid the body heat of the person holding the same will cause an expansion of the fluid up into the passage and the column in the passage will raise the rod and the doll.

After some practice, the quick placement and removal of the hand about the lower end will cause the rod and doll thereon to quickly raise and lower and the figure will appear to be dancing.

From the above description it will be apparent that the toy of my invention will afford pleasure and amusement to the user and after a period of practice will be subject to fast manipulation whereby the movement of the doll may be easily controlled.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

A toy including an integral elongated structure having a body portion and formed with a tube at its upper end having an upper transparent portion and a fluid chamber below the body, said body having a bore communicating with the interior of the tube and the chamber, a floating rod guided in the bore, a figure mounted on the upper free end of the rod, and a heat expansible fluid contained in the chamber and forming a column in the bore beneath the rod.
