' SUBIMERSIBLE TOY.

. ble Toys, of which the following is a specificationv This invention relates to a submersible toy in the form of a submarine which isactuated by air pressure supplied from an indiarubber ball and tube. When pressure is applied to the ball, air enters the hollow vessel or hull, displacing water which has been reviously admitted, and altering its speci c gravity, thus causing .it to rise. Within the vessel is a tube suitablysituated in which a projectile or torpedo is inserted,

and this torpedo is expelled by the air pumped in or by means brought into operation by the air.

. The invention is illustrated in the accompanying drawings, in which four alternative constructions are shown.

Figure 1 is a sectional side elevation of one modification in which the "air is held from escaping prior to discharge'by a valve ushed home by the insertion of a projectile. 4 ig. 2 is a sectional side elevation of another modification in which the inner end of the projectile itself forms the valve, being held the valve seat like the cork in a popgun. Fig. 3 is a sectional side'elevation of anothermodification in which the projectile is held by adetent against the valve seat until discharged. Fig. 4 is a sectional side elevation of a further modification operating in a manner similar to that shown in Fig. 3, but differing in constructive details. In each view the torpedo tube is shown loaded. r

In Fig. 1 the toy consists of a metal hull A suitably weighted to .maintain the same uprightand carrying the torpedo tube B B which isconnectedby means of tube X and valve Y to the air pressure chamber for which I use an ordinary indiarubber squeeze Z fitted with a non-return-valve.

E is a rubber bladder which fits over B and is' secured to it at either end.

Specification of Letters Patent.

Applicationfiled October 15, 1915. Serial No. 56,050.

D is the torpedo or projectile, which on insertion in the tube B pushes back the valve whdich entersthe valve seat with its forward en a The toy is placed in a pond or tank in which it sinks. On pressure being applied to the ball Z air passes to the tube B and thence through the holes L to the bladder E causing it to expand. As more air passes to it, and the specific gravity of. the toy is I altered, it rises slowly to the surface of the water. When the pressure in E and B rises to a given point, owing'for example to the bladder E being pressed against the hull A, it becomes 'suflicient to actuate the valve 0 which opens suddenly, moving forward and allowing sufiicient air to pass to expel the projectile, and then closes, the rearward enlarged end entering the sleeve C under the air pressure as the projectile leaves the tube. The use of the double acting valve. C to close the tube B after the torpedo D has been discharged prevents the inrush of water and the sudden sinking of the vessel. The valve may be so arranged that there is a small escape through a notch or port hole in the rear end so that the vessel slowly sinks as E deflates. The bladder E as it is distended may cause a small figure M to risefrom a con ning tower.

In Fig. 2 is shown an alternative construction, in which the projectile D forms a and the detent F frees the torpedo which is discharged under the air pressure. A valve C serves to cut off the escape of a1r as before.

In a further alternative construction shown in Fig. A a float may be provided in the hollow vessel, which prevents the torpedo from being expelled until itdro s with the falling water level in the vessel. Here the torpedo is held in the tube by a detent F r on a lever G, pivoted at H and having a float P at its free end. As the water level in the vessel drops, the float Psinksand presently frees the torpedo so that, as'described with reference to Fig; 3, the torpedo is discharged by the air pressure. In thisconstruction the tube B is supported in thehull A only at its forward-end, the inner end being open.
