Application led March 24, 191i'. Serial No. 157,197.

To all whom t iii-ay concern:

'Be it known that I, ROBERT H. MCCARTHY,

a citizen oi' the United States, 'residing at Madelia, in thecounty of .lVatonwan and State of Minnesota, have invented certain new and ,useful Improvements in Guards, of which the following is a specification, reference being,r had to the accompanying drawings. Y

This invention relates to certain improvements in guards and has relation more particularly toa device of this general character especially designed and adapted for use in connection with ships; and it is an object of `the vinvention to provide a novel and improved device of this general character which serves to protect the ship against injury by torpedoes or the like.

it is also an object ot' the invention topro? vide a novel and improved guard adapted to be submerged and which is provided at predetermined intervals with explosive devices which. are adapted to explode upon percussion as when struck by a torpedo or the like.

Furthermore it is an object of the invention to provide a novel and improved device of this general character which may be disposed across a harbor entrance or other- Wise submerged to afford a protection Aagainst sabina emes.

scribe the same with reference to the accom- .panying drawings, wherein- Figure is a fragmentary view in eleva tion of a guard constructed in accordance with an embodiment o't my invention;

Fig. 2 is a fragmentary View in top plan with portions broken away ot my improved `guard as herein embodied;

the diskl as disclosed in Fig. 3 with the torpedo mounted therein shown in elevation.

As herein embodied, my improved guard comprises a plurality of disks 1 preferably formed of hard steel and linked one with the other, as indicated at 2. The disks l are arranged ina plurality of vertically spaced horizontal rows and-'are substantially cylindrical in form and provided with perforate ears 3 With which the link connections 2 are engaged. The.guard Gr also includes a plu-` rality of sections which are substantially rectangular inform and defined by the man ginal chains et.

The adjacent vertical chains of the secf Vtions are adapted to 'be connected one to the other Aby the steel clevisesl arranged in predetermined vertically spaced relation. The

, upper chain i of each ot' the sections is operatively engaged with a. float F disposed lon* gitudinally thereof and positioned at either side of the section. Each of' the floats F is preferably formed of metal and is provided With a. plurality of air chambers or compartments C. By constructing` the iioats F in this manner it will be perceived that the buoyancy of the iioat will not be materially eiected should a portion thereof be injured by an explosion or from any other cause.

The corresponding faces of the disks 1 or more particularly the outer faces thereof are provided with the pockets 6 in which is adapted to be positioned a torpedo or other eXplosive medium adapted to explode by percussion. The torpedoor the like is substantially entirely confined within a pocket G and is held therein by an annular member 7 overlying an outer face of said torpedov or the like and maintained in applied position by the pliable members 8. Each 'of the members 8 is disposed through an opening 9 produced in the disk 'i and has its opposite endsbooked, asl indicated at l0. leine of the hooks 10 is engageable with the annular member or ring 7 While the second hook serves to hold the member in operative erigagement with the disk. The member 8 is also pliable so that upon the 'torpedo or the like being exploded no undue resistance will be offered thereto by the annular member or ring 7.

`When my improved guard is adapted to be employed in connection with ships the same may be held in proper position reiatiye to the vessel through the medium of 1li@ ll. il

si table cranes and when the deviee is adapted. te he disposed across a` harbor entrance or the like the Heats F may be. held or anv chore in any manner which will best meet the requirements of practice.

rein the foregoing description, it is thei rht tc be obvious that a. guard ecnftieetei'l in accordance with my invention is et an extremely simple. and comparatively inexpensive nature lind is particularly well adapted for use hy reason ofthe convenience .and vfacility `with which it may be assen'ibled, and it wiil also' be obvious that my inven 'lio-n is susmeptible oi sinne change and modilieaion without inaterial rjleparture from the prii'ieiples and spirit thereoll and tor this do not wish to be umlersl'oml as lim- L' to the precise arrangement and on of' the several parts herein shown g ont my invention in practice, hereinafter claimed.
