TOY ROCKET PnoJEoTING'GUN Rodney L. Wulfert; Webster Groves, Mo. Application January 18, 1944, Serial No. 518,748. 1 Claim. (01. 124-13) The present invention relates to an air pump equipped toy gun for shooting a rocket-type projectile from its barrel, and the primary object is to provide a unique construction characterized by the utmost of simplicity and economy in manufacture, designing and usefulness.

One phase of the invention has to do with the selection and use of a pair of simple tubes constructed from readily available sheet material, such as for example, cardboard mailing tubes, one of said tubes constituting the projectile accommodation and projecting barrel and the other functioning as the cylinder of a simple and expedient hand actuated air pump.

Furthermore, and having in mind the aforementioned qualifications of required simplicity and feasibility of manufacture, I equip the aforementioned tubes with wooden or equivalent complemental parts and accessories, these being of such form and adaptablity as to provide a substantially fool-proof air gun susceptible of ready and, safe use by juveniles and otherwise aptly designed and fitted for expedient and reliable use to a, degree commensurate with similarly fashioned play guns.

Other features and advantages will become more readily apparent from the following de scription and the accompanying illustrative drawings.

In the drawings, whereinlike numerals are employed to designate like parts throughout the same:

Figure l is a side elevational view of a so-called cordance with the principles of the present invention.

Figure 2 is a, fragmentary longitudinal view with parts in section and parts in elevation, this to pictorially bring out the selectionand arrangement of the parts. I

Figure 3 is a cross section on the plane of the line 3-3 of Figure 2, looking in the direction of the arrows.

Figure 4 is a similar view on the plane of the line 4--4 of Figure 2 looking in an opposite direction as indicated by the arrows.

Figure 5 is a side elevational view of the rocketlike projectile.

Figure 6 is an end view of Figure 5.-

Referring now to the drawings by distinguishing reference numerals, and as previously indicated, the question of materials from which the parts are made is, of course, a variable one.

Due to shortage of critical materials at the present date I have in mind using those whichmight be readily placed in the so-called scrap category. However, and regardless of this, it is to be understood that the materials employed are patentably immaterial, so to speak. With this in mind, the two tubes 1 and 8 may be conventional or ordinary cardboard mailing tubes. The upper tube '1 is preferably some 36 inches in length and approximately 1 inch in diameter. tube 8 may be'andgenerally is about 15 inches in length and approximately 1 inch and a quarter in diameter. The superposed portions of the tubes are gluedior otherwise secured together as brought out in Figures 1 and 2. A single flanged closing cap 9 of suitable material fits over and simultaneously closes the left-hand ends of the tubes 1 and 8. Inwardly of this there is a short sleeve or tube ID which constitutes a duct and I and the free end portion slides back and forth through a guide fold IS in a wooden stationary handle 16. This handle as shown in Figure 3 is of appropriate length and shape and embodies a ring-like head. I! which embraces and is appropriately secured to the intermediate-portion of the barrel or tube The upper part of this i ring is provided with a' projection having a V- rocket-type play or toy gun constructed in acl shapednotch 18 formed therein to function as a sight. The movable hand-grip l9 which is of wood and appropriate shape is provided with a sleeve 20 suitably secured to the reciprocatory rod l4. A lug-like member 2|, also of wood or equivalent material, is secured to the underside of the pump cylinder 8 and this constitutes a shoulder abutment or rest. The numeral 22 in Figure 2 designates a stop l0 arranged intermediate the ends of the barrel]. This constitutes a check for the rocket-type projectile 23.

The projectile is of appropriate materials and includes a suitably nosed head 24 fastened to an assembling disk 25 carrying appropriately attached elongated fins 26. The rear ends of the fins are of dovetail-shaped form and the inner ends are slotted and interlocked to assume the desired cruciform relationship. i

In practice, the tail or fin-equipped end of the rocket 23 is slipped into the outer open end of the barrel 1. It is forced in as faras possible with the hands. Then when the handle I9 is The lower moved toward the fixed handle l6 air is exhausted, .by suction, from the inner chamber of the barrel, thus pulling the projectile into and against the stop pin 22. grasped and zipped quickly toward the pump cylinder, the piston serves to drive the air under pressure through the duct [0 into and behind the projectile, thus forcingthe projectile out of the barrel in an evident manner.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after con sidering the description in connection with the drawings. Therefore, a more lengthydescription is regarded as unnecessary.

Minor changes in the shape, size and arrange- Obviously, when the handle I9 is barrel, a relatively short open ended pump cylinder secured to one end portion of the barrel,

corresponding ends of the pump cylinder and barrel being flush with one another, a single cap surrounding and simultaneously closing corresponding ends of said barrel and cylinder, a short lateral sleeve-like duct penetrating meeting portions of the barrel and cylinder and aifording communication between adjacent end portions of the same, a shoulder rest mounted on-and depending from the central underside of said cylinder, a piston head slidable in said cylinder, a

' closure for the remaining end of said cylinder, a

ment of details coming Within the field of invenrod connecting with said piston and slidable through said closure, a sleeve on said rod having a depending hand grip, a handle on the intermediate portion of said barrel outwardly of said hand grip and parallel to the hand grip and at right angles to the barrel, said handle having a guide passage through and beyond which said piston rod is slidable.
