The invention relates generally to toys and primarily seeks to provide a novel free flying projectile in the form of a toy rocket bomb which is propelled through the air by arapidly expanding gas released from a cartridge carried by the bomb.

Anobject of the invention is to provide a toy rocket bomb device comprising, in combination, a streamlined hollow shell-like bomb element having flight'stabilizing fins at itstail end and provision for frictiona'lly retaining therein-a compressed gas containing cartridge, and a flight launching and guiding stick having provision-for puncturing the cartridge to permit the gas to be discharged therefrom and from the tail of the bomb element to initiate and sustain the flight 7 thereof.

Another object of the invention is to provide a hollow shell-like bomb element of the character stated having internally projecting, longitudinally extending, circumferentially spaced ribs therein effective to engage and frictionally hold a gas cartridge within the element inposition for facilitating smooth flight of the element, said ribs also being engageable with the exterior of the launching stick in a manner for definitely determining the direction of flight of the element.

Another object of the invention is to provide a bomb element of the character stated in which the internal ribs terminate short of the tail end of the element, and the interior wall of the element at the tail end portion is constricted slightly'to concentrate the escaping gas andfacilitate the jet propulsion efiect thereof, the minimum diameter of said wall corresponding to the circle in which the inner walls of the ribs lie, thereby to cooperate with said ribs in the flight guiding contact with the launching stick;

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the several views illustrated in the accompanying drawings.

trating a gas cartridge and the launching stick in place just prior to a launching of the bombelement-in flight, a portion of the end of the launching stick being broken away and in section.

Figure 7 is a detail perspective view illustrating a. gas-cartridge.

In the practical development of the invention, there is provided a toy device comprising three elements, namely the bomb element, the launching stickand the propelling gas cartridge.

The launching stick is formed in two parts, one comprising a cylindricalbody 5 having a cylindrical cavity or bore 6 in its top end into which a sharp pin 'i' projects, the body of the pin being embedded in the stick as at 8. The body 5 also has a bore 9 inits lower end into which the smaller diameter mounting stick I 0 may be removably inserted, and the lower end of the stick portion l0 may be sharpened as at H so that the launching stick structure may be mounted erect, or at a desired angle by insertion in the ground in the manner indicated in Figure 1.

The bomb element generally designated I2 preferably isformed of molded plastic but may comprise alight hollow shell formed of other suitable materiaLsuch as light weight metal. When the element I2 is formed of plastic, it is preferably constructed of three sections secured together in end abutting relation by a suitable cement. The central or main body section I 3 is in the form of a cylindrical shell having a plurality, four being shown, of inwardly directed, longitudinally extending, circumferentiall-y spaced ribs 3. The ribs extend a short distance from the upper end of i the-shell as at I5 as illustrated in Figure 3, and

they similarly extend as at [6 from the lower end of the cylindrical shell and are tapered off in the manner clearly illustrated. A streamlined nose I! is cemented in abutting relation to the upper end of the shell l3 in the manner clearly illustrated in Figures 2 and 3 and said nose is formed to include anend socket 18 into which a rubber bumper i9 is inserted.

A tail piece 20 is cemented in abutting relation to the lower end of the central shell 53 and is provided with a plurality, four being shown, of flight stabilizing fins 2i. The inner shell Wall is constricted, as at 22, and it will be observed that the inner diameter of the tail shell at its lower extremity is the same as the circle in which the inner walls of the central section ribs It lie. It will also be apparent by reference to Figures 2 and 3 of the drawing that the stabilizing fins. 2:! extend a short distance below the end. extremity One of the compressed gas containing cartridges 24 is shown in place in the bomb element in Figure 6, and in detail in Figure 7, and in these illustrations it will be apparent that each said cartridge includes a cylindrical main body portion having a half-rounded end portion 25 at one end extremity thereof. At its other end the cartridge is reduced in diameter as at 26 and terminates in a reduced diameter cylindrical portion 21 of a size for fitting within the cavity or bore 6 formed in the top end of the launching body stick 5. The cartridge may be of the type well known in the home carbonization of beverages and containing highly compressed CO2 gas sealed within the cartridge shell by the readily puncturable soft metal seal 28 secured in the reduced diameter end portion 26.

When it is desired to launch the toy rocket, the launching stick may be assembled in the manner illustrated in Figure 1 by suitably inserting the lower end of the stick H1 in the ground and the upper end thereof in the receiving bore 9 in the lower end of the cylindrical stick body 5. A cartridge such as is shown in detail in Figure 7 is then inserted in the bomb element with the rounded end extremity 25 thereof centered in the nose I1 and against the stop provided by the bumper socket l8, and with the lower end portion of the cylindrical body of the cartridge frictionally held within the ribs I4. See Figure 6.

By now mounting the bomb element over the upper end of the launching stick body 5 in the manner illustrated in Figures 1 and 6, and by forcing the same downwardly along the guiding body 5 with sufiicient force to cause the cartridge end 26 to enter the body bore 6 and cause the pin 7 to puncture the cartridge seal 28, the bomb element may be launched in the direction guided by the launching stick body 5 and its contact with the longitudinal ribs l4 and the lower end extremity of the tail shell 20. The rapidly expanding gas released from the punctured end of the cartridge will impinge against the end of the mounting stick body 5 and then upon rapidly escaping from the constricted end extremity of the tail piece 20 will initiate and sustain free flight of the bomb element by jet propulsion, the fins 2| on said tail piece serving to stabilize the flight.

It will be apparent that the cartridge 24 will be frictionally retained in the bomb element during flight by its engagement within the ribs 14, and the cartridge is so positioned within the bomb element as to place the main body of the weight well forward in a manner for facilitating smooth flight of the free projectile. It will. be apparent also that the provision of the cavity or bore 6 in the top end of the launching stick body 5 and the mounting of the pin 1 therein in the manner illustrated in Figure 6 serves as a safety measure assuring against inadvertent pricking of the fingers of children playing with the toy.

While one form of the invention has been shown for purposes of illustration, it is to be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.
