PROJECTILE.

Specification of Letters i'atent. Patent d 1 10 1917 Application filed March 25, 1915. SerialNo. 17,026.

To all whom it may concern:

Be it known that I, FREDERICK MARTEN HALE, a subject of the King of Great Britain and Ireland, and a resident of Bromley, in the county of Kent, England, have invented certain new and useful Improvements Pertaining to Projectiles, of which the. following isa specification.

This invention relates to projectiles such as are described in the specification of Letters Patent of theUnited States granted to me and numbered 940,527-z'. e.,' projectiles of the type in which the bod of the rojectile is of greater diameter t an the ore of the small arm or gun (hereinafter referred to as the gun) with which it is to be used and is provided with a rod adapted to ex-- I tend into the barrel thereof.

According to the specification of British Letters Patent granted tome and numbered .267 64 of 1911, to preventsuch a projectile.

from bein accidentally exploded'before it has move sufliciently'far away from the gun to avoid injury 'to persons in proximity thereto, I provide, at the rear end of the projectile, afan device which is adapted'to be rotated by the action of the airvduring the flight of the projectile and to be thereby cause to lose a preventive effect on the relative approach of two firing elements when the projectile has traveled to av predeter mined dlstance from the gun, and I also provide means adapted toprevent the fan device from being rotated until the projectile has received its initial movement on the discharge of the gun.

Now the present invention has for its object to provide means which may be employed in lieu of, or precautionally in addi' tion to, those described in the last mentioned s ecifica-tion for preventing the rotation of t e fan device until the projectile has received its initial movement on the discharge of the gun. According thereto there is provided a device comprising a suitable part, as

a rod, which may be adapted to engage between adjacent vanes of the fan device, and an a pliance which is adapted to fit externa ly on, or is otherwise secured to, the muzzle end or fore end of the gun, and is thus adapted to secure the said part thereto in such a position that, when the projectile is home on the gun ready for firing, the said part will enga c with a vane of the fan device, or otherwise with the fan device, so as to prevent the projectile from becoming armed by the rotation of the Ian device until the pro ectlle has received a'sufficient initial aforesaid part.

The Invention, which consists of the varimovement to free the fan device from the i ous features hereinafter defined, is illusposition on the I gun.

1 Figs. 2 and 3 are a side and an end view respectively of the example shown inFig. 1

Figs. 5 and 6 are a side and an end view respectively of the example shown in Fig. 4. Figs; 8 and 9 area sectional side elevation and an end view respectively of the example shown in Fig. 7. i

In each of the Figs. 1, 4,and 7, the projectile 1, which is provided at its rear end with a fan device 2 arranged and adapted to operate so as to arm the projectile after it has traveled to a' predetermined distance from the gunas, for example, in the manner described in the specification of my aforesaid British Letters Patent 26,764 of 1911 is shown mounted in osition on the barrel. 3 of the gun. In eac case the projectile is shown provided with an inertia ring 4, which is adapted to prevent the fan device 2 from being rotated until the projectile has received its initial movement on the discharge of the-gun, but which is adapted to be moved rearwardly in relation to the body'of the projectile, owing to its inertia, upon the shock of discharge, so as then to allow rotation of the fandevice and the subsequent arming of the projectile. Although this inertia ring 4 has been shown in each of the Figs. 1, 4, and 7 referred to above, it is to bejunderstood that it may be dispensed with if desired, since its function is similar to that of the means which form 'the subject-matter of the present invention,

tween adjacent vanes of the fan device, but

obviously any otherenga ementwhich will obtained upon the clip.

screws 15, to the stock of the gun.

prevent the fan device rom turning and thereby arming the projectile may be effectedfor example, the rod 5 might be arranged merely to abut against apart of the fan device so as to prevent rearward longitudinal movement thereof.

In the particular example shown in Figs. 1, 2, and 3, the rod 5 is mounted on alug 6 formed on one branch of a spring clip .7, which is' adapted to be sprung upon the muzzle end or fore end of the gun when required. For the purpose of facilitating the springingof the clip upon the gunand its removal therefrom, there is formed thereon a ring piece 8 through which the finger is intended to. be passed to enable a grip to be 'In the example shown in'Figs. 4, 5, and 6, the rod 5is provided with a screw clamp which is adapted to be firmly secured on the muzzle end or fore end of the gun when required. The two jaws 9 of the clamp are mounted on one end of the rod 5, and at the side opposite the hinge the two jaws are formed with lugs adapted to be drawn together by means of a nut 10 and a screw 11 which is mounted on a in 12 in the lug on the lower jaw of the 0 amp. The lug on the upper jaw is formed with a slot 13 adapted to accommodate 'the screw 11 when it is swung about the pin 12 into such a position that. the nut 10, when screwed down, will cause the sleeve 10 to engage with the lug on the upper jaw.

n'the example shown in Figs. 7 8, and 9, the rod 5 is attached to the gun by means of a bracket 14 into which it is screwed, and which is suitably fastened, as by mean sl plf e bracket 14 is permanently fastened to the stock, but therod 5 is intended to be screwed into or unscrewed from the bracket when desired.

In each of the examples shown, the rod 5 (with or without the appliance for attaching it to the gun) is readily detachable from the gun, as is preferred. It will be obvious that there are many different wa s of attachin the rod 5 to the gun other t an those herein efore described, and therefore it is clear that many modificationsmay be made without departing from the scope of my present invention.

What I claim is.-
