PROJECTILE FOR LINE-THIQOIUING GUNS.
Application filed March 3, .1922.
T 0 aZZ whom 2'25 may concern:
Be it known that I, GEORGE NORMAN, a subject of the King of Great Britain, residing at 322 Mansel Road, Small Heath, Birmingham, England, have invented cer tain new and useful Improvements in or Rslating to Projectiles for Line-Throwing Guns.
This invention relates to improvementsin projectiles for line-throwing guns, and refers more particularly to projectiles of the kind which have attached thereto a line, and are adapted to be passed into and over the barrel of the gun, and are projected into the air by means of a blank cartridge or other suitable explosive charge.
The object .of the invention is to provide an improved construction and arrangement of projectile of the aforesaid kind, whereby the force of the explosive gases is more fully and effectively utilized in the discharge of the projectile thereby extending the flight or range of same; and means for connecting the line to the projectile which permit of greater accuracy in flight being obtained than with projectiles for line-'throw ing as at present in use.
Another object is to provide means whereby water or moisture is prevented from reaching the cartridge or charge after the projectile has been, placed in the gun.
The invention consists in the employment of a projectile comprising a rod which is adapted to slidably enter the barrel of the gun, and a tubular sleeve which is arranged to surround or envelop the barrel of the gun, the said rod and sleeve part being connected together at their upper outer ends by means of a suitable nose part or cap which is preferably arranged to rest on the outer end or mouth of the barrel of the gun, and at the inner or lower end of the aforesaid sleeve part or envelope, means are provided for the attachment thereto of the line, or attachment cords or wires to the end of which. the line may be secured.
In order that my invention may be clearly understood and readily carried into effect I will describe same with reference to the accompanying drawings, in which Figure 1 shows in part sectional elevation a projectile constructed. in accordance with this invention, mounted in position on the barrel of a gun ready for firing.
Specification of Letters Patent.
Patented June 6, 1922.
Serial No. 540,735.
Figure 2 shows an end and side elevation of the projectile.
Figure 3 shows inlongitudinal section the disassembled sleeve part and nose or cap of the projectile and an elevation of the rod.
Figures 4: and 5 show respectively a sec tional elevation and a side elevation of a modified means for detachably connecting the halyard or line to the projectile.
Like numerals of reference. indicate the same feature or part throughout the several figures of the drawings.
According to one embodiment of this invention, as illustrated in Figures 1 to 3 .of the accompanying drawings, I provide a rod 1 which is of a diameter somewhat less than the bore of the bar-rel 2 of the gun, so as to perm-it, when discharged therefrom, of a minimum of frictional resistance, and on the upper or outer end of the said rod is secured a nose part or cap 3, which in one form may be screwed on to the end of the rod 1 and further secured or locked thereon by a cross pin or peg 4;.
To the outer diameter of the aforesaid nose partor cap is screwed or otherwise secured a tube or sleeve part 5 which is adapted to surround or envelop the outer diameter-of the barrel2. If desired, the nose part 3 and the aforesaid tube or sleeve 5 may be formed integral.
At the lower end of the sleeve part or envelope 5 of the projectile, provision is made for the attachment of cords or wires, to the outer end of which the halyard or line is connected.
In a preferred arrangement I form near the lower end of the aforesaid sleeve part 5 six longitudinal slots 6, and three alternate bars or ribs 7 between the said slots are raised or bulged outward to permit of the cord or wire 8, to which the line or halyard 9 is connected, being threaded or passed therethrough, and such is intended to pre vent rubbing contact of the cord 8 with the outer face of the barrel 2 when the projectile is discharged; also, the aforesaid means for connecting the said cord 8 are adapted to permit of the use of a. single piece as illustrated, whereby it is connected to opposite sides of the sleeve 5, or if desired, cords may be attached to each of the lugs 7, but in either case it will be observed that the connections of the cords to the projectile are balanced so as to prevent deflectionof same during its flight.
In a modified. arrangement, as shown in Figures a and 5, the attachment cords 8 are detachably connected to the sleeve part5 of the projectile, by means of a ferrule .10 having formed thereon or attached thereto two or more lugs 7 to which the cords 8* are attached, the said ferrule 10 being flared at its lower end 11, and adapted to frictionally engage with the correspondingly flared end 12 of the sleeve 5 The ferrule 10 is preferably arranged to protrude beyond the lower end of the sleeve 5 to per mit of it being released or detached by means of a knock or blow on its outer protrading end.
The line 9 which is coiled in a canister or other suitable device adapted to permit of the ready uncoiling or paying out of same, may be connected to the' attachment cord or cords 8 by means of halyard clips 13, or if desired, it may be tied or knotted thereto.
In the discharge of my improved con struction and arrangement of projectile, the operation is as follows The explosive gases impinge against the lower end of the rod part 1 thereof, thus forcing same outward through the barrel of the gun. Owing to the free fit of the rod 1 in the bore of the barrel 2,'a portion'of the gases escapes bet-ween the said rod and the barrel, but such is pocketed in the sleeve or envelope 5 by the cap or nose part 3 on the outer end thereof, and thus utilized or employed in the projection of the projectile.
Further, by reason of the attachment of the halyard or line 9 to attachment means which are connected to the lower end of the sleeve part 5 of the projectile, its posi tion or direction in flight is not altered, as is the case with projectiles at present in use. wherein the line is attached to the upper end of the projectile or a part formed on or secured thereto and arranged to pro trude beyond the muzzle of the gun, thus greater accuracy in firing is obtained.
When the projectile is placed inthe barrel of the gun, by reason of its sleeve part 5 completely covering the mouth of the barrel th entrance of water or moisture is effectively prevented, thus protecting the cartridge or charge from damage.
It will be readily understood that my improved construction and arrangement of projectile, by modification insize, is applicable for use with guns of various types, adapted to be fired from the shoulder or from a pedestal or bracket, or for discharge from a mortar or small cannon.
Having fully described my invention, what I desire to claim and secure by Letters Patent is:
1. A projectile for use in line-throwing guns, comprising rod adapted to slidahly enter the barrel of a gun, a tubular sleeve adapted to envelop the barrel of the gun, and a nose piece connecting the rod and sleeve at their outer ends and adapted to rest upon the mouth of the barrel of the gun.
2. A. projectile for line-throwing guns, as claimed in claim. 1. wherein the rod has an easy fit in the barrel to reduce frictional resistance during the discharge of the projectile, and to permit of the passage of a portion of the powder gases into the sleeve or envelope, to assist in the projection of the projectile.
3. A projectile for line-throwing guns, as claimed in claim 1, wherein the sleeve is provided near its lower end with means to receive attachment cords for connecting the projectile to the line or halyard. v
a. In a projectile for line-throwing, guns, as claimed in claim 1, a flared portion on the inner end of said sleeve and means for detachably connecting the projectile to the line, comprising a ferrule having thereon lugs to receive the attachment cords, and provided at its'lower end with a conical part adapted to engage with the flared end of the sleeve of the projectile.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
GEORGE NOR-MAN.
