MEANS FOR CARRYING LIFE-LINES.

Specification of Letters Patent.

Patented Sept. 9, 19113.

Application filed September 21, 3913- Seriel Ito. 721,642..

To all whom it may concern:

. Be it known that I, BENJAMIN F. MOCREARY, a citizen of the United States, and a resident of the city of New York, Jamaica, borough of Queens, in the county of Queens and State 01' New York, have invented a new and Improved Means for Carrying Life-Lines, of which the following is a full, clear, and exact description.

The invention relates to life-saving apparatus used for carrying a life linefroni shore to ship and viceversa, or to a high building or other structure.

The object of the invention is to rovide a new and improved means for carrying life lines and arranged to prevent the projectile carrying the life line from tumbling over during its flight and to cause the projectile to travel a great distance.

For the purpose mentioned use is made of a projectile in the base end of which is centrally anchored one end of a wire cord or cable extending through a groove formed lengthwise in the peripheral face of the projectile, and a line attached to the free end of the said wire cord or. cable. Use is also made of a projectile provided with a recess for the reception of a lifeline anchored a one end in the bottom of the recess, the other end of the line terminating in a ring resting against the base of the projectile, and engaging means for catching the ring at the time the projectile 1s fired out of a gun or mortar.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the means for carrying life lines; Fig. 2 is a sectional side elevation of' another means for carryin a life line, part of the gun or mortar belng shown in elevation; Fig. 3 is a front end elevation of the same; and Fig. 4 is a rear end elevation of the projectile and the ring of the life line in expanded state.

The projectile A, shown in Fig. 1, is adapted to be fired out of a gun or mortar B by the use of a suitable explosive C, and in the base of the projectile A is formed a tapering recess A for the reception of the doubled-up end D of a wire cord or cable D adapted to be fastened in the said recess A by being wedged by the use of lead E or other suitable material. The cord or cable I), after passing out of the recess A extends along a recess A formed in the base of the projectile A to then extend along a grooveA rformed lengthwise in the peripheral face of the projectile A. The outer end of the wire cord or cable D terminates in a.

ring D to which is attached one end of a life line F of suitable length. When the projectile A is fired out of the gun or mortar B then the projectileafter leaving the gun carries along the wire cord or cable D and the latter draws along the life line F. Now it will be seen that by the use of the wire cord or cable D a flexible, strong and nonburnable connection is had between the projectile A and the life line F, and conseguently the life line is carried safely to its estimation by-the projectile A and the wire cord .D. By having the cord D connected centrally with the base end of the projectile A the latter is not liable to tumble over during its flight, as the pull of tbelprojectile A on the wire cord D is centrally from the base of the projectile. 'It will also be noticed that by this arrangement the projectile A can be fired with reat accuracy so as to insure the safe de ivery of the line F to ship or shore or other part.

The projectile G, shown in Fig. 2, is adapted to be fired out of a gun or mortar H provided with a suitable explosive charge C, and the projectile G is provided with a recess G open at the base and containing a coil of life line I, the forward end of'which is preferably formed into a knot I or doubled-up, and is wedged in a recess J 2 by the use of lead J or other material, the same as above described in reference to the wire cord D. The rear end of the life line I terminates in a rin I which is somewhat larger in diameter t an the rojectile' G, but is pressed into the bore 0? the gun or mortar K and rests on the base of the projectile GQ One or a series of hooks K is attached to a "split band L clamped on the muzzle end of the gun or mortar H, and the said hooks K are adapted to catch the ring I when the projectile G is fired and passes out of the gun or mortar H, it being understood that when the projectile G passes out of the gun and with it the ring I then the latter expands by its own resiliency so as to readily engage one or more of the hooks K. When the ring I engages the hook or hooks K then the life line I is drawn gradually out of the recess G on the projectile G continuing its flight until it reaches its destination and consequently the life line extends between the hooks K and the part reached by the projectile. It is understood that the points of the hooks K are out of the path of the projectile but are in close proximity thereto, so th the ring I on expanding is readily caught by one or more of the hooks K at the time the projectile G is fired.

From the foregoing it Will be seen that the life line F or I does not unduly hamper the projectile A or G '11 its flight; thus insuring a safe delivery of the life line at the desired destination.

Having thus described my invention gaim as new and desire to secure by Letters katent: I
