fwh'ichlccmmunicates through" the port Z9 with theinterierpf the `chamber i9 iiring the gas charge, VVvvith the resultthat the 'gases are ds- 55 comprising a firing pin 21 having a head 38v which is pressedv backwardly by the Spring 39 which carries with it the head 4B of the'corrugated member 4| having theiiint plunger 42 operating in the chamber 43 and pressed by the spring 44.

Referring to the modication as shown in Figure 3, it will be noted that-in this case a-bar" of carbide designated 45 Vwhich is. wealfrened along the lines 46 is pressed by the lspring 41 under the screw top 48 downwardly through the chamber I8 in the ammunition containerlS. in the path of the reciprocating plunger 49 which is adapted to shear the bar of ammunitioni45 into blocks of equal size along theV linesv 46,v discharging one block at a time into the water |5. The plunger 43 is pivoted at 50 to the actuating lever 5| which is pivotedat 52 on the ammunition container .|9. This lever 5| is spring pressed by the spring 53 to hold it against the top of the bar of ammunition 45.

Referring to the modification in Figure 4, I have provided in this -arrangement a strip of ammunition comprising a series of pellets' 54 1 which are carried on ap'aper strip or between paper strips 55. This strip is fed over the ammunition opening I6 by the corrugated feed wheel 56 having teeth 51. This wheel is pivoted at 58 on the pivot ofthe actuating arm 5| which carries the pusher and shear member 49 that has a cutting edge 49a.v for shearing the paper .strip to release the pellet 54 so that it can drop in the'water 5.

Spring members

59 and 60 carry it respectively on the housing |9 and the. z lever 5|, which serve to regulate the movement of the corrugated wheel 56. 'I'heammunition strip is preferably wound on the carrier pin 55a. Y Referring to the modification in Figure 6, where a projectile is used with a time fuse and expelling charge, I provide a cylindrical projectile 6| having an expellingcharge 62 in the base with an oppositional cover 63 acting as a` gas check and also as a support for the base 64 .of the figure 65 which extends through to the upper end of the projectile beneath the cover 66. Aparachute 61 is wrapped around thegurc so that .the entire thrust is on the figure and not' upon the parachute. The parachute is attached tothe figure by the parachute cords 68.

The expelling charge 62 is led by the time fuse 69 which constitutes` a powder charge compressed within the sleeve 16. This powder is vexposed at 1| to the flame passing through the opening 1 upon the explosionV of the carbide gas as heretofore described.Y The projectile is forced out of the gun by this explosion and the time fuse is ignited so that after 'the o projectile reaches a predetermined height, the time fuse will burn through and ignite the expelling charge 62, blowing the gure Y'and the parachute wrapped around it out. of the kprojectile, enabling the parachute-tocome, down open', with the thrust member suchas the figure 65 being then used as the weight to draw the parachute back to earth.v y i i Referring to Figure 10, it will be observed that I employ an ammunition chamber |9 to which there are fed a plurality of cylindrical pellets 12. Due to the angular position of the cannon, these pellets feed downwardly by gravity so that the bottom one rests against the bottom wall of the ammunition chamber I9 at |9a. Over this last pellet is a spring restricting plunger 13 held vbackwardly by thevspring 14 which can be depressed by the finger piece 15 to drop `the last or bottom pellet into theV water I5. Upon the withdrawal of the plunger 13, the next succeeding pellet will drop into position for the feeding operation.

. At the-same time it will seal the discharge `opening I6 through which the pellet has been delivered to the water I5. When the gas is gen- `verated, it makes its exit into the gun barrel 5 through the passageway 1 over the flint firing -move these flints against the ratchet surface of the member 8|. As Ythe-carbide gas'ows over the flint mechanism, itis red so as to drive the rubber-ball 8 or any other projectile out ofthe cannon.;

. In Figure. 11 isY shown a modified form of ammunition consisting of a carbide stick 86 weakened at intervals at 81 so that a pellet 88 can be broken off to drop into the water. I5 and then the swingingcover 89 will close the discharge opening I6 and firing can take place. This stick may have acover of thin paper, water-proofl material, gelatin or the like to pro tect it before Ait is dumped Yinto the water. These sticks 8S willfbe furnished to the trade in closed containers such as bottles so as toI preserve the carbide. The advantage of this construction Yis that it eliminates special loading mechanism.

4The stick vStor the pellet v'|2 may have such a coating as described indicated at 90, which is shown partially broken away in Figure 11.

It will be further noted in connection with` the member A8| that it is partially cut away at 78|a. to provide a Vent. .In non-firing position the `member 8| closes the'port 1 but in firing position it. opens the. port .1 to permit the carbide' gas to `flowinto the gun barrel 5. This facilitates the firing by the notched steel member 8| striking against the flint. This arrangementpermits the gas to be held in the generating chamber until the ball is placed in the end of the cannon;v Ity eliminates escaping of the gas without functioning and there is no chance for the explosion travelingdown into Vthe generating chamber. This permits more carbide to be placed in the generating chamber Vthan could be ordinarily placed therein as the gas flowV will be governed to such an extent that the eiciency of the cannon willfbeI greater than has Vbeen heretofore possible, as heretofore it has been impossible to control the gas flow.V

According to my method, I prepare and supply a gas 'forming charge such as a pellet or block of carbide of known strength to a measured quantity of water, one pellet at a'timev,y

and' only one. This makes the apparatus safe for children so that an excess Vcharge cannot be inadvertently placed in thercannon. Then- ,and itmay serveto ignite the time fusein the expelling charge of the projectile. -I desire to comprehend within my invention such modications as may be clearly embraced within the claim and scope ofv my invention.

What I claim as new and desire to secure by 1. In a 'gas cannon, an' ammunition means comprising a storage chamber,` having a lateral discharge opening at one end and a valve member between saidv chamber and dischargeopeningv rotatably mounted therein and having a slot adapted to receive onemammunition member at a time in one position and to discharge said member 'in another position while preventing the remaining ammunition members'from discharging, and means associated with said valve membei'- to positively eject an ammunition member through said dischargeV opening. Y

2. In combination in a gas cannon; an ,ammunition means comprising an ammunition storage chamber for storing an ammunition strip, means for feeding saidrstrip and means for shearing portions of said strip and ejecting the sheared portions tothe cannon.
