BUOY.

Application filed December This invention relates to a buoy for marking the location of objects under water, such for example as a sunken ship,v and it is the object of this invention to provide a buoy which is strong and durable and not liable to get out of order under severe usage and which permits of easily and readily attaching a stay line thereto which connects with the sunken or submerged object so as to definitely determine its location.

In the accompanying drawings Figure 1 is a side elevation of the buoy constructed in accordance with my invention and showing the same attached by a stay line to a sunken ship for locating the latter Figure 2 is a top plan view thereof.

Figure 3 is a vertical section of the same.

Figure i 'is a horizontal section taken on line and, Fig. 3.

Similar characters of reference indicate 'like parts in the several figures.

1n the drawings a ship 10 is sunk to the bottom of a body of water 11 is represented in connection with my improved buoy for marking the location of the ship and thus facilitate raising the ship or removing the valuables therefrom.

The buoy is connected with the sunken ship or other object by astay line 12, the lower end of which may be attached to a reel 13 on ship board and which may be unwound therefrom as the ship sinks and pay out enough line to permit the buoy to float on the surface of the water.

My improved buoy comprises in its general organization a buoyant body and means for attaching the upper end of a stay line thereto. 1n the preferred construction the body consists of a hollow sphericalY inner shell 14 of rubber which is comparatively thick and strong'and an outer shell 15 of sheet metal, such as copper, which'is comparatively thin. The inner shell may be made in two semi-spherical sections arranged one above the other and the horizont-al joint 1G between the same may be sealed by any suitable rubber cement. The outer shell may likewise be made of two superposed semi-spherical sections, the joint 17 between `which is sealed by soldering or brazing in a well known manner; Y e

Arranged in the upper and lower parts of the body are two bushings or ferrules 18 9, 1925. Serial No. 74,227.

each of which extends vertically through the two shells thereof and is provided with outer and inner flanges 19, 2O bearing against the outer side of the outer shell and the inner side of the inner shell, respectively. A leak tight joint may be produced between each of these bushings and the body by soldering the outer flange ofthey same to the outer metal shell. The bore of veach bushing is provided with an internal screw thread and two bushings are connected with each other so as to hold the body distended by a tie rod 21 which passes diametrically through the body and engages threaded portions 22, 23 near opposite ends thereof with the internal threads of the bushings. are preferably soldered to the tie rod to exclude water from the interior of the buoy body. The extremities of the tie rod project laterally beyond the side of the buoy body so as to form attaching pins 24, 25.

around which the stay line is wound and fastened by tying or otherwise to form a connection between the stay line and buoy. In order to effectively embrace the buoy body and reliably connect the stay line therewith, the outer shell of the body is provided with one or more circumferential grooves V26, preferably two in number which are ar-.

ranged atA right angles to each other and divide the body into quarters. `The stay line `in addition to being wound around the end pins of the tie rod, also engages with the several grooves 2G, whereby the stay line is reliably held against circumferential displacement and thereby forms a strong con'- nection between the buoy and the stay line which will ensure definite marking of the location of the sunken ship so that the same can be reached with ease and facility.

As a whole lthis buoy is very strong and notl liable to be crushed by the laction of storms and the same permits of quickly attaching a line thereto in case of emergency so that the place where the ship is sunk can be marked if the, same has to be abandoned hastily. i

Iclaim as my invention A buoy comprising a -spherical body hav- The latter ing an inner shell and an outer shell,` said v` inner shell consisting of semi-spherical rub ber sections, the joint between which `is sealed, yand ksaid outer shell consisting ofV semi-spherical metal sections, the joint between which is sealed, bushings extei'iding through diametrically opposite parte of the inner and outer shells of said body and each having an internal screw thread und inner and outer flanges bearing respectively against the inner side of the inner shell and the outer side of the outer shell, and a tie rodi. i
