W TAM Mfl% Patented Nov. 13, 1945 k C ORD HOLDER FOR LINE THROWING GUNS Alfred T. La Pierre, Worcester, Mass., assignor to Harrington & Richardson Arms Company, a corporation of Massachusetts Application December 19, 1944, Serial No. 568,853

4 Claims.

This invention relates to a container for holding the cord for a line throwing gun.

Objects of the invention include the provision of a novel holder or canister for containing and paying out the cord for a line throwing gun, said canister being provided with means for attachment to the gun so that the same may be operated by a single person and obviating the necessity for holding the cord on a separate support, said canister being provided interiorly thereof with a spring pressed plate bearing against one end of the spool of cord to maintain the same in correct and non-snarling position while the cord is paying out after the gun has been fired.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a view in elevation illustrating the novel canister attached to a line throwing gun in position ready for firing;

Fig. 2 is a cross sectional view through the canister;

Fig. 3 is a view in end elevation thereof; and

Fig. 4 is a detail view of a modified canister.

In the operation of line throwing guns it is important that the gun shall be easily and quick- 1y available for use and that the cord shall freely and easily pay out so as to render the gun accurate and incapable of failure due to snarling of the cord, and this invention accomplishes these purposes.

In Fig. 1 there is shown a line throwing gun I having a barrel l2 and a forearm [4. This gun is shown as having a projectile I6 loaded in firing position in the barrel and a cord I 8 is secured to the projectile. A line cord holder or canister 20 is provided with straps 22 secured to the stock and barrel so that the gun forms a unitary apparatus capable of operation by one person. When the gun is fired the projectile I6 is of course thrown forwardly and turns over once so that the cord trails. The cord pays out from the canister during the flight of the projectile.

The canister is provided with a flanged forward opening at 24, this opening being rolled to provide a smooth edge so as to avoid fraying of the cord. The rear end of the canister is open and is closable by a cover 25 having a connection with the canister as for instance a bayonet type slot 28. The cover 26 is provided with a guide pin 30 secured thereto by any desired means on which is mounted a plate 32, said plate being movable the length of the guide pin interiorly of the cana ister. Springs 34 are interposed between the cover 26 and the plate 32 for the purpose of extending the latter forwardly to the limit allowed by pin 30.

Instead of using the coil spring shown in Fig.

2. a leaf spring such as at 3B in Fig. 4 may be 'utilized without departing from the scope of the invention.

When the canister is empty, the cover 26 is removed together with the plate 32, the guide pin, and the springs. A spool of line cord as shown at 38 is inserted in the canister with the leading end protruding from the open end 24 and the canister is then closed by means of the cover with plate 32 resiliently impinging upon the rear end of the spool of cord. The springs force the spool against the forward end of the canister so that the spool is resiliently but firmly located therewithin and hence the spool cannot vibrate or bobble in the canister. By reason of this fact, the cord will pay outwardly from the interior of the spool smoothly and without snarling until such time as the spool becomes lax due to sumcient removal of cord. After this point the cord will not snarl in any case.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

l. A cord holding canister for line throwing guns, said canister having an aperture therein at its forward end for paying out the cord, said canister being open at its rear end, a cover for the rear end of the canister, and means associated with said cover for maintaining a spool of cord in generally fixed position in the canister.

2. A canister for holding a spool of cord for a line throwing gun, said canister having an aperture in an end thereof for emission of the cord, said canister being open at the opposite end, a cover for the open end of the canister, a plate movably mounted on said cover, and resilient means urging said plate against a spool of cord in the canister to locate the spool in substantially fixed position.

3. A canister for holding a spool of cord for a line throwing gun, an opening in one end of the canister for paying out the cord, said canister being open at the other end, a cover for closing the open end of the canister, a guide pin on said cover, said guide pin being on the same axis as that of a spool of cord in the canister, a plate on the guide pin, and springs urging the plate away from the cover and into engagement with a spool of cord in the canister to maintain the spool in position in the canister.

4. A canister for holding and paying out a spool of cord for a line throwing gun comprising a hollow body, an end wall therefor, said wall having a rolled edge opening for paying out the cord, a cover for the opposite end of the canister, and means resiliently urging a spool against said end wall.
