CEDRIC HAROLD HANWELL, 0F NORTHAMPTON, ENGLAND.

TOY CANNON, PISTOL, GUN, AND THE LIKE.

Application led January 2S, 1923.

To all vwhom it 77mg/ conce/ML.'

Be it known that I, CEDRIC HAROLD HAN- wiiLL, a subject of the King of Great Britain, residing at Northampton, England,

have invented certain new and useful Improvements in Toy Cannons, Pistols, Guns, and the like, of which the following is a specification.

li/Iy invention relates to toy cannons, pisf tols, guns and the like, of the type in which the propulsion of the projectile is effected by the ignition of a combustible mixture.

My invention has for its object to provide a toy of the type indicated above, in which 17 the loading and iiring is eifected in an improved manner.

My invention consists in a toy of the type indicated in which the propellant is introduced into a iring chamber, disposed in the it breech of the gun, the firing chamber being provided with vents communicating with the barrel chamber containing the. projectile.

My invention further consists in the improved toys to be hereinafter described.

now to the accompanying drawings which illustrate my invention, and form part of my specification,

Figure l shows a plan and Figure 2 shows an elevation of one form of my invention, while Figure 3 shows a sectional elevation.

Figures l and 5 show detail sectional and end elevations respectively of the firing chamber.

2:"v In carrying my invention into effect according to one form, and as applied by way of example to a toy cannon, using a match of the Swan Vesta. type of ammunition, I form a barrel l, Figures l, 2 and 3, with a 1U small bore for the greater portion of its length and an enlarged bore in the breech portion.

In the enlarged breech portion a iiring chamber 2 is introduced which has inclined ducts 3, Figures 4 and 5, formed therein for allowing the explosion gases to pass from the firing chamber into the barrel portion and expel the projectile 4.

A hole 5 is provided in the forward end of the firing chamber to allow the match head to be ejected after firing by means of a ram rod.

To the rear of the match head a pointed striker 6 is disposed, which is adapted to be fo eed forward when desired by releasing a Serial IIo. 615,728.

trigger 7, rotatably mounted on the pivot 8, attached to the gun carriage` YThe forward ends of the springs 9 are connected to the pin l0 on the trigger 7, the rear ends of the springs being connected to a pin l1 on the gun carriage.

The arrangement of the springs and trigger is such that when the latter is withdrawn to the. retracted position, the line of action of the springs pass through or over the centre of the pivot 8, of the trigger so that the latter remains in this position.

The cannon is mounted on wheels l2 and the carriage is provided with an elevating screw c)13.

In order to load the cannon the head of a match is cut off from the stem, and inserted with its dipped end outwards in the {iring chamber 2.

The striker 6 is next inserted in the firing chamber, and these parts are then inserted in the breech. The trigger 7, ismade toV contact gently with the striker and pressure exerted on the trigger to compress the charge in the firing chamber. stem of the match is then inserted from the muzzle end, and forms the projectile.

To fire the cannon, the trigger 7 is retracted and released when itl is forced forward by the springs, so as to contact sharp- 1y with the striker and fire the match head in the firing chamber.

The gases -of explosion issuing through the vents 3 cause the match stem to be projected with a force sufficient to carry it for distances ranging from 2O to 30 feet.

Iir some cases instead of using matches of the above type, matches of the safety type may be used. In such cases, the bore of the firing chamber is lined with a piece of paper or other material, prepared so as to cause ignition of the match head when in rubbing contact therewith.

The match head when using safety matches is not initially compressed as above described, and is fired by rubbing against the lining of the chamber as it is driven forward by the striker.

Again, in other cases I may use any suitable form of explosive mixture instead of a match head in which case the hole 5 in the inner end of the ring chamber would be dispensed with as it would not be necessary to use a ram rod to dislodge the residue.

Although I have described my invention lill) .and having the breech port-ion of larger bore ythan the front portion thereof, a removable tiring chamber in said breech portion, said iringchainbe-r ha fing a restricted opening at itsfforivaid end with ducts iiiterceptiiig said restricted opening and communicating with 'said i'iont portion, a pin in the tiring chamber, aiidstriliin means engaging the pin for igniting a vignopell'aiit in said tiring chamber.

2'. ln combination a4 barrel having the breech portion of larger bore than the front portion thereof, a removable' firing chamber adapted to be inserted longitudinally in said breech portion, said firing chamberibeing formed with ducts to establish communica'- tioii between the interior of said chamber and the front' portion of. the barrel around the charge'in saidliring chamber, said front portion together With striker means operaA tive in and Jior igniting a propellantin. said `tiring chamber, as set'fortlr In combination, a barrel having the breech portion of larger bore than the front portion thereof, a removable firing chamber in said breech portion having ducts communicating With said front portion, striker pin disposed in said firing chamber, a carriage for said barrel, together with trigger means mounted on said carriage, and co-acting with said striker pin to ignite a propellant in said firing chamber as set Vforth.

4. In combination, a barrel having a breech portion adapted to receive a pro ellent charge therein and provided With diict means arranged laterally of the charge space and communicating with said barrel portion, Wholly beyond said propellant, together with means for igniting a propellant in said breech portion, substantially as described.

1n combination, a barrel having a breech with a restricted opening yat its for Ward end, and duct `means communicating With and arranged laterally off said restrict- `ed, opening and communicating with the front portion of said barrel together with means for igniting a propellant in said breech portion.

6. ln'combination, a barrel having a breech portion of larger bore than theI front portion, a liring chamber iii said breech portion and having aprestricted `opening at its forward end With duct means communicatportion oit larger bore than the tioiit'po'r-r tion, a removable liring chamber in said breech portion and having a restricted opening at its forward end with duct means communicating with and arranged laterally or said restricted opening and communicating With said front portion, together with means vfor igniting a propellant in said breech portion.

8. ln combination, barrel having an enf larged breech portion to rece-ive charge. means for compressing tnecharge iii said .breech portion, said breech portion being formed with a plurality of openings to establish communication between the barrel and enlarged breech portion, said openings being arranged radially of and Wholly beyond the charge receiving space.

9. In combination with a barrel enlarged to form a charge receiving space, of means iviereby said space is at all times in open communication with the barrel irrespective of the charge Within the space.

ln testimony whereof l have signed my name to this specilication.
