NEW JERSEY j TOY cannon Application filed December 13, 1929. Serial No. 413,876.

This invention relates to toy cannons, and has for an object to provide an improved construction which is simple and yet which effectively propels a projectile when prop- Another object of the invention is to provide a toy cannon preferably made from wood and using a complete rubber band as the motive power, the structure being such in that the projectile may be propelled without the rubber band becoming displaced.

A further object, more specifically, is to provide a toy cannon having a reciprocating power member actuated by a rubber band .15 with the rubber band fitting into a suitable slot in the reciprocating member and coacting with other parts of the cannon, whereby it is always held in proper place and yet maintained in functioning position.

In the accompanying drawing- Figure 1 is a side view of a toy cannon disclosing an embodiment of the invention;

Figure 2 is a top plan view of the cannon shown in Figure 1;

Figure 3 is a fragmentary sectional view through Figure 1 on the line 3-3.

Referring to the accompanying drawings by numerals, 1 indicates a frame having a gear piece 2 adapted to rest on the ground or other support. The frame 1 is supported by suitable wheels 3 held in place by a journal pin 4 extending through the lower part of frame 1. Preferably frame 1 is a single piece of wood, and the wheels 3 are preferably of wood, though they may be made of other material. By providing disk wheels and a flat surface to the frame 1 the wheels are properly guided with a minimum effort. On top of the frame 1 is arranged the barrel 5 of the cannon, said barrel being secured in place by adhesive or other suitable means. This barrel is provided with a suitable bore 6, and in this bore is permanently mounted a power member or rod 7 which extends beyond the breach 8 so as to present a'handle 9 and also to receive a stop or abutment member 10. Member 10 is provided with a slot 11 for receiving part of the rubber band 12. The barrel 6 is provided with a slot or kerf 13 for receiving part of the band .12.

On the respective sides of the barrel 3 are provided side members 14 and 15, these members being formed with grooves 16 and 17 for accommodating part of the rubber band 12, as shown particularly in Figure 3. The members 14; and 15 with their grooves act to hold part of the rubber band in the kerf or slot 13, and yet permit the functioning of substantially the full length of the band when a ball or other projectile is to be projected through the air.

From Figure 1 it will be noted that the parts are so proportioned that barrel 5 is at a slight angle. This is not necessary but is desirable, because it will allow a ball or ing the handle 9 the rubber band 12 will quickly move the parts back to the position shown in Figure 2, and consequently, will propel or project the ball or other projectile for an appreciable distance. It will be noted that the band 12 is a complete band and may be an ordinary rubber band, though a special rubber band may be used, if desired. In use the handle 9 is grasped and pulled until band 12 is stretched to the desired extent. A ball or other projectile is then dropped into the muzzle and allowed to move down the bore 6 until it strikes the end of the impeller 7. hen the parts are in the position just set forth the cannon is ready to be discharged, and the discharge takes place immediately upon releasing the handle 9. When the handle 9 is released band 12 quickly moves the impeller 12 until. the abutment 10 strikes the shoulder 8. "While this is taking place the projectile is given sufficient momentum to be projected an appreciable distance, the distance being naturally in proportion to the strength of the power member 12.

What we claim is 1. A toy cannon, including a barrel having a bore extending therethrough, said barrel having a notch formed therein extending downwardly from the upper surface, a pair of side bars connected with said barrel and.

with one end extending to a point in line with said slot, each of said bars having a groove on the under surface, a rubber band having a portion fitting into said notch and part fitting into said groove, an impeller slidably mounted in said bore, and a notch member connected with the said impeller adapted to receive part of said band whereby when the impeller is moved in a certain direction said band will be brought under tension, and when released said band will function to quickly move the impeller back to. its starting point to project a ball or other projectile from said bore.

2. A toy cannon, including a barrel having a notch therein a rubber band having portions fitting into said notch, a sliding impeller slidably mounted in said barrel and connected to said rubber band, and means for preventing said rubber band from moving out of said notch when the band is brought under tension said means including grooved side members extending laterally from said barrel with the grooves facing downwardly for receiving part of said band.
