1 Claim.

This invention relates to toy boats, and more particularly to toy boats of the type propelled by the action of a chemical pellet which, when in contact with water, produces a change in surface tension causing the boat to be propelled.

A main object of the invention is to provide a novel and improved toy boat of the type propelled by the reaction of a chemical pellet, whereby changes in surface tension are produced causing the boat to be propelled, said boat being very simple in construction, being very attractive in appearance, and being arranged so that the chemical pellet may be utilized with maximum emciency.

A further object of the invention is to provide an improved toy boat of the surface-tensionpropelled type, said toy boat being very inexpensive to manufacture, being sturdy in construction and being provided with means whereby loss of the pellet through careless handling of the boat is avoided.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is a top plan view of atoy boat constructed in accordance with the present invention;

Figure 2 is a cross-sectional view taken on line 2-2 of Figure 1;

Figure 3 is a perspective view of a modified form of toy boat constructed in accordance with the present invention.

Referring to the drawings, and more particularly to Figures 1 and 2, ll designates the hull of the boat, said hull being formed of light plastic material or of light wood, such as balsam wood, the hull being formed with a main body portion l2 and a longitudinal notch l extending inwardly from the rear end thereof intermediate the sides and terminating at a point of the front end of the main body, the notch II), the bounding side walls I4, l4, and a top Wall 15 forming a rear cabin portion [3, the top wall terminating at its rear portion in an inclined wall element It. The side walls l4, l4 terminate at their rear portions in outwardly-flaring inside surfaces l1, IT. The top wall [5 is formed with an upwardly-projecting cylindrical, tubular extension l8, resembling a smokestack, which, as will be subsequently described, provides a means for inserting a pellet into the cabin portion of the boat. Designated at I9 is a screen member of light metal screen or the like, said screen member having a horizontal reticulated panel or bottom portion 20 and a vertical reticulated panel or rear portion 2!, the forward edge of the bottom portion 20 being secured at 22 to the bottom of the hull body l2 and the top end of the vertical screen portion 2| being secured at 23 to the under side of the cabin top wall I 5. The screen I9 is coextensive in width with the interior of the cabin l3 and defines a compartment in which may be positioned a pellet 24 of suitable chemical composition, for example, a mixture of aerosol and sugar, which has the property of reducing the surface tension of water when it comes inv contact therewith. In operation, thea propelling force on the boat which propels the boat forwardly. This action continues until the pellet 24 is completelydissolved, at which time a new pellet may be dropped into the compartment defined by the screen l9 through the tubular stack l8.

In the modification illustrated .in Figure 3, the hull of the boat is designated at 25 and is formed of a suitably-shaped piece of light material, such as balsam wood or light plastic material, the rear or stem end of the hull being formed with a square notch 26 extending inwardly from the rear end thereof intermediate the sides and terminating at a point short of the front end of the hull, and a piece of light metal screen 21 being secured to the under side of the hull underlying the notch 26 and forming with the walls of said notch a compartment on which may be positioned the chemical pellet 24. In operation, the boat is placed in the water and the pellet 24 is deposited on the screen 21, whereby said pellet interacts with the water to. produce reduced surface tension, whereby propelling force is developed, moving the boat forwardly in the same manner as in the modification described in connection with Figures 1 and 2.

While certain specific embodiments, of a toy boat have been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of V the appended claim.

What is claimed is:

A toy boat comprising a hull having a longitudinal notch extending inwardly from the rear end thereof and terminating short of the front end of said hull, a hollow cabin surmounting said notch and secured to said hull, a horizontally disposed reticulated panel positioned on the under side of said notch and secured to said hull, and a vertically disposed reticulated panel positioned contiguous to the end of said hori zontally disposed panel adjacent to the rear end of said hull and secured to said hull and forming with said horizontally disposed panel and adjacent portions of said cabin a compartment, the top of said cabin having an upstanding stack 15,

for introducing a pellet into said compartment.
