TOY CANNON.

Specification of Letters Patent. Patented Aug 12 1919 Application filed August 19, 1918. Serial No. 250,512.

To all whom it may concern:

Be it known that I, GEORGE C. LAsAREs, a citizen of the United States of America, residing in Springfield, county of Hampden, and State .of Massachusetts, have in vented a certain new and useful Toy (,annon, of which the following is a specification.

This invention relates to improvements in toy cannons of the type in which a plurality of projectiles are retained in a suitable holder or magazine and with means for propelling the projectiles one by one, in rapid succession, from the lowermost one of the pile. The propelling means comprises a lunger that is operated in one direction liy means of a rotatable shaft to which a suitable arm is attached, this arm serving the purpose of retracting the plunger to allow a projectile to fall from the magazine into the bore of the cannon, and, at the same time'serves to compress the propelling spring. Suitable means is provided for supporting the cannon comprising wheels which are located on opposite sides of the barrel. The shaft or rod'upon which the wheels are located also serves the purpose of an axle for the wheels, and, as a connecting means between the rear supporting part of the cannon and a block which supports the barrel proper.

Referring to the drawings:

F'gure 1 is a plan view of the improvement showing the operative mechanism comprises, in general, a slidable plunger, means for retracting and releasing the plunger and for compressing the propelling spring to eject the projectile;

Fig. 2 is a vertical sectional View on the line 22 of Fig. 1, through the axis of the barrel, illustrating the operative parts, the plunger retracting and spring compressing means being in the normal or inoperative positionin which the plunger supports the pile of projectiles and the propelling spring is in an expanded condition;

Fig. 3 is a transverse sectional view on the line 33 of Fig. 1 looking in the direction of the arrow, and showing the manner of supporting the plurality of projectiles one above the other in the holder;

Fig. i is a transverse sectional View on the line -1L of Fig. 1, showing the propelling plunger, the vertical slot through the same, the arm in the slot for operating the same: and the vertical opening through the barrel; and

Fig. 5 is a perspective view of the plunger with the angular-shaped member pivotally attached thereto, which receives one end of the propelling spring, the other arm of the member projecting downward below the lower side of the plunger.

Referring to the drawings in detail; 1 deslgnates the base-part of the cannon which rests upon the floor or other support, as indicated at 2. This part is formed with a forwardly projecting portion 3 which enters the notch & in the lower side of the block 5. Passing through the portion 3 in the block 5 is a rod 6. This rod serves the double purpose of securing the base part 1 and the block 5 together, and also as an aXle o1 shaft for the supporting wheels 7 of the cannon. The barrel of the cannon is indicated at 8 and is formed with a bore 9. This bore extends into an opening 10 which receives the pro-pelling plunger 11,- a. detail view of which is shown in Fig. 5. The plunger is formed with the vertical opening 12therethrough and the forwardly extending part 13 of the plunger which en gages the projectile, the outer end portion ofwhich is chamfered or inclined, as indicated at 14. The bored-out part 10 of the barrel extends to the rear end of the barrel 8. This bored out part is closed by means of the block 15, the reduced part 16 of which enters the opening 10. 10 designates a shoulder against which the plunger 11 strikes when a projectile is fired. 11' designates the shoulder on the plunger that engages the shoulder 10. The block 15 is formed with a bored out recess 17 to receive the propelling spring 18. This block is secured to the base-piece 1 by 11183118015 the screw 19 and assists in rigidly retaining the barrel 8 in place.

Pivotally attached to the open end of the plunger 11 is an angular-shaped piece having a rearwardly extending portion or arm 20 and a downwardly extending portion or arm 21. The attaching pivot is indicated at22 and permits the spring 18 to have free movement during its operation. The rearwardly extending arm 20 receives the for ward end of the spring 18 while the part 21 enters the longitudinal opening 23 in the lower part of the barrel 8. The part 21 serves the purpose of preventing the plunger 11 from rotating about its axis and also serves as a guiding device for the backward and ing 12 and the opening 23 must always be of such length that it passes completely through the barrel 8 and through the opening 12 of the plunger when the same is operated. When the crank 25 is rotated the curved portion of the arm 26 moves the plunger 11 rearwardly and, at the same time compresses the spring 18. As the tip end of the arm 26 leaves the part 21 the plunger is released and the spring recoils. The forward end 13 engages the lowermost one of the pile of projectiles 28, and forcibly expels the same through the bore of the barrel 8. The inclined portion 14 of the part 13 serves the purpose of allowing the projection 13 to pass under the projectile next above, but will prevent its being expelled by the part 13. A weight 30 serves the purpose of moving the remaining projectiles downward as they are expelled. These projectiles are mounted as shown in Fig. 3 in the wire rack 31. This rack is substantially of hairpin formation, the parallel sides of which enter the annular groove 31' in the projectiles, and, the enlarged portion 32 serves to permit the projectiles to be inserted in the rack. The lower end part 33' is separated as shown and enters openings 34 in the barrel.

It will be seen from this construction that the projectiles can be expelled readily by simply rotating the crank to which the arm 26 is attached. During the compression of the spring the lowermost projectile drops into the bore 9 of the barrel, and, when the spring is released the plunger forcibly drives this projectile from the barrel.

It will further be seen that the invention is simple in construction and one that can be easily assembled without unnecessary labor.

It should be noticed that a platform is provided in the bore of the barrel immediately in front of the plunger receiving part of the barrel, and onto which the projectiles fall from the magazine. The lowermost projectile falls onto this platform as the plunger is retracted. The projectile next above rests on the reduced part of the plunger.

It will. be observed that the oppositely located curved walls of the elongated and enlarged opening in the barrel at the rear of the bore serve to support the plunger during its reciprocating movements as clearly shown in the sectional views of Figs. 2 and 4.
