21 Claims. I

This invention, which relates totoys, has for its object the creation of a toy rocket gun which may be safely used by children and yet will be realistic in operation, and which may be produced at a reasonable market price.

Another object of the invention is to provide a toy rocket gun which may be operated, both in the propulsion of the rocket from the barrel and in the flight of the rocket, by air charged into the rocket before the gun is fired (i. e., before the rocket is released) and which exhausts from an open tube at the rear of the rocket; in this respect the toy realistically simulates a real rocket. A further object is to make the operation more realistic by providing means for producing a cloud or smoke which escapes with the compressed air through the exit tube to leave a trail of smoke behind the rocket. iAn allied object is to produce this cloud or smoke by means including the use of chemicals or inert substances which are harm-- less. A further object is to add to the realistic operation of the novel toy by providin means associated with the said exit tube for producing a whistle or other sound effect as th charged air flows therethrough in flight of the rocket.

Viewed from another aspect, the object of the invention is to provide a toy rocket gun, operated by air compressed into the rocket, which, by the construction of the barrel, the rocket and associated parts, will eifectively propel the rocket from the barrel and maintain it in flight for substantial distances, but which will not have sufficient momentum to injure either the person or furniture or the room. A further object is to provide a toy rocket gun which may be aimed at designated targ ts and which will call for skilful, as distinguished from haphazard, operation in causing the rocket to hit the designated target. An allied object is a toy rocket gun having a barrel which is angularly adjusted to change the angle of elevation of the projected rocket. Another allied object is a toy rocket gun having an air-charged rocket, the flight of which may be predetermined by the pressure of the air charge and by other manipulations at the barrel (as will be described).

For the attainment of the foregoing and such other objects as may appear or be pointed out herein I have shown two embodiments of my invention in the accompanying drawing, wherein Fig. 1 is a side view of the toy rocket gun employing an air bulb for charging, the barrel and most of the rocket being in section;

Fig. 2 is a front view of the toy rocket gun of Fig. 1, looking at the forward end of the rocket in its barrel;

Fig. 3 is a side view of the toy rocket gun employing a compressor for charging, the head end of the compression being in section and a portion of the frame broken away; and

Fig. 4 is a rear View of the toy rocket gun of Fig. 3, looking at the closed end of the barrel.

Referring first to Figs. 1-2, the toy rocket gun comprises a frame having a base 9 and a pair of upstanding side plates 8, B, a barrel it closed at its left end H and open at its right end, and an air-tight rocket 2%). Base 9 and its side plates 8, B are stamped from sheet metal, the upper or distal ends of side plates 8, 8 being pierced by aligned apertures l, 1. Barrel Iii, which is also made of sheet metal, has arcuate flanges or segments H, il, see Fig. l, tongued out of the sheet metal at diametrically opposite sides of the barrel, see Fig. 2, and located substantially at the midpoint of the barrel length, Fig. 1. Arcuate flanges ill, il' fit in the aligned apertures 17, l of the side plates 8, 8, for pivotally mounting the barrel so that the angle of elevation may be changed as desired; this fit is tight so that the barrel will be frictionally maintained in the desired inclination.

Rocket 28 is also made of sheet metal but must be made air-tight, and is preferably made of thin gauge, light material to reduce its weight. Rocket 28 has the nose contour 22 of a rocket or projectile and a similar rear contour including rear tube 2! and sloped end 23. Sloped end 23 terminates in an aperture 2d into which open tube 2i is forced so that portion 2! extends rearwardly of the rocket and a portion 25 extends interiorly of the rocket. The tube is fitted securely in aperture 2G and made air-tight by soldering or the like. Near its forward end rocket 29 has an annular recessed shoulder 29 latched by a springpressed pin IE on barrel Hi to hold the rocket within the barrel.

Means are provided for closing the open end 26 of rocket tube 2! when the rocket is in its barrel and is being charged with air. .As shown in Fig. 1, this means comprises a rubber disc 12 and a metal disc l3 each of a diameter somewhat less than the internal bore of barrel iii, and a coil compression spring i i. In assembling, spring 1 3 is first inserted, followed by the metal disc i3 and then by the rubber disc [2. The discs are then forced inwardly to compress the spring and to move rubber disc E2 inwardly of a pair of tabs l6 tongued-out of the barrel, whereat tabs it are turned inwardly as shown to furnish a pair of stops against which rubber disc l2 abuts and is forced by compressed spring 54. The rubber may be smaller in diameter or thinner, and adhered to the outer face of metal disc [3.

Rocket 26 is inserted in the open end or mouth of barrel lil with its rear tube 2! foremost. The rocket may be freely inserted, i. e., without force, until open end 26 of rocket tube 2! abuts the rubber disc I 2. To complete the insertion, the rocket must be forced inwardly against the compression spring l4, its rear tube 2| moving discs l2 and I3 inwardly away from stops lb. This inward forcing of the rocket is continued until its annularly recessed shoulder 29 arrives at a point at which latch pin l9 snaps in front of the shoulder to 3 hold the rocket in latched (and fully inserted) position, as shown in Fig. 1. Rubber disc l2 pressed against open end 26 of rocket tube 2: by compressed spring M, the rocket being held by latch pin I51, furnishes a closure for the open tube during the time the rocket is being charged with air under pressure (as will be subsequently described). In addition, the compressive force of coil spring It adds to the propulsive force ii.- parted to the rocket by the reactive force of the compressed air blowing out of exit tube 2| 'when the rocket is released (by withdrawing latch pin [9, as will be described). Lastly, the provision of the compression spring and a floating rubber disc l2 will provide an effective closure for exit tube 2! even where the tube had not been precisely positioned in aperture 24 to provide a rear tube extension of a predetermined dimension.

The stop lugs l6 may be omitted and the discs secured to the coil spring anchored to closed end ll of the barrel. In some cases the rubber disc or a rubber pad may be adhered directly on closed end II of the barrel, or omitted entirely and the open end 26 of exit tube 2! abutted against closed end H.

Latch pin I9 is housed within a tube 6 which is force fitted in a hole 5 pierced at an upper point near the open end of barrel iii. The upper end of latch pin l9 extends upwardly beyond tube 6 to furnish an exposed portion l5 which may be grasped for withdrawing the pin. The upper end 4 of tube 6 may be closed or crimped-in to provide a bearing for the latch pin. Latch pin. [9 has a small cross-pin 39, the ends of which are received in a pair of diametrically opposite e1ongated slots 3 in tube 6. A coil compression spring 2 is interposed between closed end i of the tube and cross-pin 39 for forcing latch pin is downwardly to protrude its lower end into the barrel. This end of the latch pin has a bevel l8 facing the open end of the barrel, so that the rocket, more particularly its inclined rear portion. 23, will cam the latch pin outwardly as the rocket is being inserted. The latch pin is so positioned that, when the rocket is fully inserted and coil spring I4 compressed to the proper extent, it will snap in front of annularly recessed shoulder 29 of the rocket, as shown, to latch the rocket in place While being charged with air.

A short, narrow tube 38 is force fitted in a hole in the rocket near its forward end 22 and a short-distance rearwardly of annularly recessed shoulder 29. A short portion 3! of the tube extends exteriorly of the rocket, and the juncture between the tube and the outer surface of the rocket is made air-tight by soldering or the like. The end 32 within the rocket is closed by crimping, swagging, soldering or the like. The portion of the tube within the rocket is pierced by an opening 33 in the tube wall near the inner surface of the rocket. A strip 34 of resilient material is secured, as by soldering, at the upper, closed end 32 of the tube, with the lower or distal end portion of strip 34 closing tube opening 33. Tube thus constitutes an inlet for charging the rocket with air under pressure and a check valve for preventing escape of the air compressed into the rocket. One end of a rubber tubing 35 is slipped on exterior portion or nipple 3! and air forced under pressure through Opening 33 of the tube, the air pressure flexing the distal end of resilient strip 34 away from the opening to permit the air to enter the rocket. When the air pressure in rubber tubing 35 drops or when the tubing is removed, the resilient and flexed strip 34 will return to normal position closing opening 33 and will be held in closing position by the air pressure built up within the rocket.

The barrel i0 is cut away at its open end for the major portion of its periphery to leave an arcuate overhang 36 at the upper part of the barrel mouth. The aforementioned hole 5 for latch tube 6 is provided in this arcuate overhang 36. Arcuate overhang 35 extends rearwardly of the barrel, Fig. 1, to a point where the major portion .i of the barrel periphery terminates. As clearly shown in Fig. 2, terminal edge 31 of the barrel occupies the major portion of the full circle, leaving a relatively small arcuate terminal edge (arcuate overhang) 36. And as shown in Fig. l,

major terminal edge 31 of the barrel mouth is' somewhat to the rear of the position occupied by air inlet 3| of the rocket when the rocket is latched in the barrel. By cutting away the open end of the barrel in this manner and by extending recessed shoulder 29 of the rocket annularly around the rocket, the rocket may be inserted in the barrel with its inlet nozzle 3| disposed at any angle (i. e., within the large angle, which is the major portion of a full circle, subtended by recessed terminal edge 3'! of the barrel mouth).

A suitable chemical which will produce smoke or fumes by the action of air or a suitable inert substance, such as powdered chalk, talc or the like, which will mix with the air to produce a cloud, is inserted through rear exit tube 2|, into the interior of the rocket, indicated by reference character 5. The portion 25 of the rear exit tube extending interiorly of the rocket, by spacing the tube opening away from the interior surface of the rocket, prevents the material I from directly entering the exit tube 2| in any position of the rocket in flight or in barrel I 0, inclined at the desired angle of elevation. The air forced under pressure into the rocket will react with material I or mix therewith to form a cloud or smoke which will pass through the rear exit tube with the flow of air therethrough when the rocket is released for propulsion and flight, and leave a trail of smoke behind the rocket, to realistically similate an actual rocket. It should be noted that opening 33 of tube 30 is close to the interior surface of the rocket so that the in-ilow of air under pressure through opening 33 will sweep along the interior surface of the rocket to effectively agitate, mix with or interact with, the substance I deposited along the interior surface.

The end of the interior portion 25 of the exit tube is beveled to a fine point to provide a sharp circular edge 2'! at the entrance to the exit tube.

As the air under pressure flows past sharp edge 21 into the exit tube, a shrill sound or whistle is emitted as the rocket leaves barrel l0 and continues in flight. Other means may be provided for producing a sound effect, such as tiny holes 28 pierced through interior tube portion 25, or a narrow strip 38 formed by slitting the thin wall of the tube at its end portion, which strip acts as a reed.

The rocket may be charged with air in any suitable manner; in Fig.1, this is an air bulb 49 connected by rubber tubing 35 to inlet nozzle 3!. Air bulb :30 may be of the type having an opening 4| at one end over which the thumb is held when 7 the bulb is compressed and removed when the bulb is released and extended by air entering opening 4|; or it may be of the type having a check inlet valve. Instead of the air bulb an air pump may be used, similarly connected to the 75 rocket inlet 3! by rubber tubing. After the rocket 5. is sufficiently charged with'air, rubber tubing 35 is slipped off rocket nozzle 3! and latch pin l9 withdrawn to release the rocket for propulsion and flight.

In Figs. 3-4 the toy rocket gun is implemented with a simple air compressor. The base 9' of the frame is somewhat longer and has a similar pair of side plates 8', 8 at the upper, distal ends of which barrel IE! is pivotally mounted in the mannot described above with reference to Figs. 1-2. Underlying barrel to provide sufficient clearance for pivoting the barrel and close to base 9 is an air cylinder 42 provided with a pair of diametrically opposite, laterally extending fins '43, :13, which are slidably received in a pair of elongated slots 53, 53 in side'plates 8, 8' of the frame, whereby air cylinder 42 may be reciprocated. Fins 53, 3 each have a laterally projecting pin 44 received in slots 54, 54 at the distal ends of a pair of fork arms 5!, 5! which together with a common handle 52 constitute a bifurcated lever 50, Forks 5|, 5i are disposed outwardly of side plates 8', 8, Fig. 4, and are pivotally mounted, at the common pivotal mounting of barrel H3, at the upper, distal ends of the side plates. For this purpose, the forks 5|, 51 each have an inwardly directed protuberance 5'! which is received within the hole defined by the arcuate flanges or segments IT, IT tongued out of the barrel. The bend 55 of bifurcated lever 50 is sufficiently above the barrel It! to provide clearance for angling the barrel. Handle 52 of the bifurcated lever is manipulated back and forth to turn the lever and reciprocate air cylinder 42,

The head end 45 of the cylinder has a central aperture 46 for a piston rod 4? and may be provided with suitable packing (not shown) to prevent air leakage from the air cylinder as it is reciprocated relatively to piston rod 41. The latter is secured, as by nuts 48, 48, at its outer end to an upstanding lug l9 tongued out of base 9 of the frame. The inner end of piston rod 4'! is secured, as by screw threads, to a piston 56 which has a leather cup 58. In this manner piston 5% is held stationary as air cylinder 42 is reciprocated. Air is admitted, upon the suction stroke of the cylinder (to the right, Fig. 3), into the head end of the cylinder through an aperture 59 in cylinder head 45. A strip 69 of resilient material is secured at its lower end to cylinder head 5 with its upper, distal portion covering aperture 59 and provides a check valve allowing ingress of air upon the suction stroke and closing aperture '59 when the air cylinder is moved leftwardly, Fig. 3, on the pressure stroke. A short tube or nipple BI is provided at the head end of the air cylinder and is connected by rubber tubing 35 to the inlet nozzle or nipple of the rocket.

The closed end II of barrel i0 is provided in Figs. 3-4 with a centrally located threaded member 62 which may be turned to abut the inner end of screw member 62 with the discs l2, it within the barrel to force rubber disc l2 more tightly against the open end 25 of rocket exit tube 2|, see Fig. 1, where it is desired to build up the air pressure within the rocket to a higher degree than would be permitted by coil spring Ill.

Inlet nozzle 3!, Figs. 1-2, extends but a short amount beyond the rocket. But to avoid the possibility of this being broken off, the inlet arrangement of Fig. 3 may be used, in which tube 30" is flush with the rocket wall and is larger than tube 30 of Fig. 1 to provide an inner bore 62 which will frictionally receive one end of a nipple 64 the other end of which is permanently secured in rubber tubing 35. Nipple 64' has an" opening or openings 63 which align with aperture 33 of tube 30'. The outer surface of nipple 64 and the inner bore 62 of tube 30 may have a rib and. groove arrangement to compel the nipple to be properly inserted in tube 30', with its open i'ng 63' aligned with aperture 33 of the tube. When the rubber tubing is disconnected from the rocket, its nipple 64 is simply withdrawn from the bore 62 of tube 30", leaving nothing to project from the rocket surface. Nipple 64 may be designed so that but a short length thereof enters the bore of tube air; in this case the nipple need barrel open at one end pivotally mounted on the frame, an air-tight rocket having a central opening at its rear end and an annul'arly recesssed shoulder near its front end, a rubber disc and a metal disc of slightly smaller diameter than the bore of the barrel near the closed end of the barrel with the rubber disc outermost, lugs tongued-in from the barrel, a compression coil spring between the closed end of the barrel and said metal disc for forcing the discs outwardly with the rubber disc abutting the lugs, the said rocket being inserted at the open end of the barrel with its said rear opening abutting the rubber disc, a spring-pressed latch pin outwardly beveled and positioned at the open end of the barrel to snap in front of the said recessed shoulder of the rocket upon a full insertion thereof in the barrel, the rear end of the latched rocket forcing the rubber disc rearwardly against the compression spring to establish an air-tight closure at the said rear opening of the rocket, an inlet fitting having a pressure check tightly secured in the rocket, and means connectable with said inlet fitting for charging the rocket with air pressure.
