To all whom 'it may concern:

Be it known 'that I, INoniiie'r J. GLERUM, a citizen of the United States, residing at Devils Lake, in the county of Ramsey and State of North Dakota, have invented certain new and useful Improvements in Life- Line Projectiles; and I do declare the f ollowing to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to malte and use the semen This invention relates to improvements in projectiles for carrying life lines.

One object of the invention is to provide a projectile of this character constructed in such manner and of suoli material that it will not injure anyone' when falling to the ground after having been projected for cnrrying the life line to the desired point.

Another object is to provide a life line projectile of this character having an imroved construction and arran ement wherey the line will freely uncoi and pay out fron the projectile without becoming tanle g Another object is to provide means where by the compressed air or other propelling Huid will be prevented from disturbinu the arrangement of the line in the projecti e or interferin with the proper unwinding of the coils W en the projectile is discharged.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more full described and particularly pointed out in t e appended claims.

In the accompanying drawings: Figure 1 is a side view o my improved line'cerrying projectile; Fig. 2 is a. similar view showing the parts separated; Fig. 3 is a centrallongiformed of tudual sectional view of the projectile; Fig. 4 is a. vertical cross sectional view on the line 4-4 of Fig. 1; Fig. 5 is n. longitudinel sectional view of a. modified form o the projectile. Fi 6 is a detail sectional view of a portion o the pro'ectile showing the menner in which the dis rs are arranged between the balls of cord in the projectile and the manner in which the cord passes around end between the disks from one ball to another.

My improved projectile is preferably paper but may be constructed of any. siiitab e material which will not be likely to cause injury or damage when felling to the ground after having been projected.

The projectile as shown in the first figures of the drawing comprises a tubular cylindrical body portion 1 in the outer end of which is arranged a bullet shaped head 2 formed of suit-able material for imparting the proper weight to the outer end of the projectie und to partly overcomel the resistance of the outpaying of the line. The head 2 is detacliably secured in the outer end of the body 1 in any suitable manner and is here shown as being preferably secured by means of a series of studs 3 formed on the inner surface of the outer end of the body 1, preferably formed by indenting the side of the tube as shown. In the outer side of the inner end of the head 2 is formed a series of right angularly shaped grooves 4 in which the studs 3 are adapted to be engaged when the head is inserted into the outer end of the body and turned in the proper direction thereby fastening the head in the end of the tube und forming a fluid tight joint.

The line is arranged in the body 1 of the projectile in the form of a series of balls 5 wound in the same manner as an ordinary ball of twine is wound and between each two balls when placed in the body 1 is arranged a series of loose disks 6 formed of peper as shown in Figs. 3, 5 and 6 separating the balls and preventing the nressure of the air or other projectin iiuid rom dislocn-ting the coils in t-he ba s of the line and thus causinlthe latter to pay out double or to become ngled. The inner end of the line of one ball is passed diametrcally around and between the disks'between it and the next ball and is connected with the outer end of the line of the next ball toward the inner end of the projectile, und the outer end of the line of the first ball in the front end of the irojectile being connected to the head or en of the projectile. The inner end of the rear or-innerinost ball in the projectile is secured in any suitable manner in the end of the gun barrel from which the projectile is thrown. The pressure of the propelling fluid, in the absence of the separatin disks would tend to press the balls tege er an cause their adjoining coils to become matted or entangled but this is preientecl by the disks, an as the end of the line of each ball is reached in paying out the line, the pull on the line will tip the -in rane ortction or from sli dicke of the series consecutively but in opposite directions so that the continued eyout of the line will not be inter ered w1 In order to prevent the contente of the projectile from becoming damp or from bein disturbed in any manner the rear end of e projectile is preferably sealed by c suitable oep 7 which is preferably constructed o f wax paper or other similar materiel, seid oep being adapted to bc 'removed when the pro'ectile ie placed in the gun, In the rear en of the proectile is crranhed c sto coller 8 which is a opted to hold e ball mly pressed together and to revent the seme from bein shaken while out of the rear en of the projectile while e latter is in motion. The co ler 8 is glued or other wise suitably secured to the inner side of the pro'ectile In 5 of'the drawing'is shown c. Slightly modiied construction of projectile 9 `1n which the outer end of the tube is crun ed or otherwise drawn together and seele by luing or otherwise cementing the 'come to er to form e duid tight closure.

The lat er form of the projectile is adapted more especially for use in connection with lince thrown over or into a. burning building v vherein there is danger of the projectile str1 the occupnntsof the build' or when wn over the building from flgin i uponn one passin by the o csite side o the bui d' B orming' ero'ectile without .euhgead just described IihcJseme will be light in weight and will not be c t to injure any one if struck thereby. In th form of the pro ectile the bells of cord or twine forming t e line rovide the necessary wel ht for ecus accurate projectile ie eee fet-merece there cra o su cien rnu e roectilto esa over e buildein and own on t e opposite side thereo Frein the foregoing description taken in connection with the accompanying drewinge, the construction and operation of the invention will be readily understood without g a more entended explanation erious Ieh es in the form, proportion endthe minor etails of construction may Ucplel et this yatcnt my he attained for me centi smh, by cddrcssing the Uommluioner closed andV etgrcjeotile to be' en e beresorted to without depertin from the' rinciple or sacrificing any ol he advences of the invention as claimed.

loving thus described my invention what I claim is:

1. A life line rojectile comprising c tn bulcr body po on, s. line di oecd therein arranged in e series of balle ev' their end connected to ether, n. series of d1s1cs errcuged between t e bells of the twine forming the line, means to hold the belle lirml pressed together and toprevent the be rom being shaken while 1n transportation and from sliding out while the projectile is in motion, and means to cloee and seal the inner end of the pr ectle 2. A life line projectile comprising a tubular lndricel body portion, a heed heving a. etechable engagement with the forwurd end of seid tubular body portie a lined' osedineeid tube erren edin -e form o e series of balls, the ou er end of cach of which is connected to the inner end of the next forward ball, means to seperate seid balls and to revent the rcssure of the propelling terferin wi the pro er unwindmg of the linlen c ccp adept to close the :rear end of e projechle when the letter is not in use.

8. A projectile of the character described comprising a. tubular' body ortion conq structed of light materiel an havin its forward end sealed to form e, huid ght closure, s line arranged in said'tube, seid line comprising a. series of balls arranged in the body portion of the projcc series of loose dislrscrren d between said elle, e collar-arr edin erecrendoftheprojectile to ho d the bells 1n plo and c removable ce adopted to be cpp to the rear end o the tubular body rhon'of the roectile whereby the rear en of the letter 1s osed and sealed end the contents thus protected.

In testimony whereof I have hereunto eet my hand in presence of two subscribing wit n.
