To ILZZ 1071/0112, it may concern:

Be it known hat I, BURKARD BEER, a citizen of the German Empire, residing at Hamburg, in the State of Hamburg, Germany, have invented certain new and useful improvements in Devices for Projecting Life- Lines, of which the following is a descrip tion, reference being had to the accompanying drawings and to the letters of reference marked thereon.

This invention relates to a device which is adapted for projecting or firing life-saving lines. For this object a ring capable of engagement with the shot is mounted in front on the gun-barrel, to which ring the life-saving line is suspended and which is carried along with the shot.

The characteristic feature of the present invention consists in the shot being surrounded at those places on which the ring engages with a casing of softer metalsuch, for instance, copper or leadwhereby the shock when the ring is struck and carried along is diminished.

Some forms of construction of the object of the present invention will now be explained, and these mainly embrace two groups. In the one the ring is mounted on the shot when carried along with it, while in the other the shot engages over a projection of the ring, preferably provided with spring tongues or protuberances. In all the forms of construction, however, the resting-place of the ring on the shot according to the present invention is made of softer material. Preferably the shot is made hollow and filled with a propelling substance, which imparts a more exact direction to its flight and also makes the same visi ble in darkness.

The object of the present invention is shown in several forms of'construction in the accompanying drawings, in Wl1ich- Figure 1 is an end view, and Fig. 2 an axial longitudinal section, of a shot and ring according to the first form of construction. Fig. 3 shows an elevation of the shot and a ring of altered form mounted on the barrel,

art of the barrel being shown in section. Fig. 4 is another view of this ring and shows the introduction of an intermediate member between the ring and the line for better absorbing the shock. Fig. 5 is an end view,

and Fig. 6 a longitudinal section, of the shot and ring in a second form of construction. Fig. 7 is an end view, and Fig. 8 is a longitudinal sectional view, of the same.

l The shot (1 (shown in Figs. 1 and 2) is cylindrical and hollow and also provided with l a cupola-shaped point. According to the j present invention the shot or projectile in i one form of construction is provided with a casing b, of soft 111aterial-such, for instance, as copper or lcadwhich is slightly tapering in front. The life-saving line 'L is attached to ing the line 'i. This ring has a conical bore g, corresponding to the cone of the shot a, in which bore the shot a after being fired enters, and in this manner carries with it the ring f and the line i. Another shape of this ring is shown in Figs. 3 and 4, in which, instead of the tapering bore, it has a cylindrical bore Z. Also instead of one lug h, as shown in Bigs. 1 and 2, several such may be provided. 'lhus, for instance, in big. 4 a ring 3/ is shown with two such lugs Zr, and here, in addition, between the line i and the ring y a spring intermediate mcmber m is also interposed, where by the shock arising when the shot carries the ring with it is still better absorbed.

In the shots 0 and 25 (shown in Figs. 6 and 8) the ring in being carried with them is not mounted on the casing of the shot, but the latter engages over a corresponding projection of the ring. For this object on the ring g in Fig. 6 a conical projection w is provided, and similarly on the ring to (shown in Fi 8) a cylindrical projection 2, which carry above spring hooks or protuberances r. The respective shots 0 and t areprovided with suitable conical and cylindrical recesses or turned out parts s and 1 respectively, which serve for receiving the projections, while on the ring 9 and 'w, being carried along with the shots, the hooks r are first compressed by reason of their elasticity and then engage behind corresponding shoulders 1" on the shots 0 and t, so that their hold is secure. Here also the respective resting-places p and u, according to the present invention, are covered with softer metal.

Preferably all the shots are filled with a propelling substance of, the gas of which can escape during the llight through a perforation formed in the bottom.

ll aving now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In combination, a line-carrying ring adapted to be carried by the muzzle of a gun,

the lug lb of a ring], which is mounted on the mouth e of the barrel and serves for conveyber, spring-fingers thereon, and a projectile projectile having shoulders for interlocking with said fingers.

5. In combination, a line-carrying member, spring-fingers therein, a projectile having a tapered recess for the reception of said fingers, said recess having a lining ol yieldable material.
