Application filed June 22, 1917. Serial No. 176,330.
a menace to navigation within a certain radius about a ship; or other structure upon which the instrument is mounted. It consists primarily of a series of reflectors co operatively so arranged as to show upon a magnifying-mirror the surface-of .the sea,
and objects thereon within the given radius,
so that it may be conveniently observed by the look-out in the loolrouts cage. Thus enabling the proper oiiicials of a vessel to be instantly warned of any danger, so as to defend itself if armed, and to escape if unarmed.
Other objects and advantages of my invention will become apparent during the continuance of the following description.
In the drawings:
Figure 1 is a View in perspective, showing my invention without the search-light cage.
Fig. 2 is a view of my invention with the search-light cage.
'In both gures the numeral 10 designates the mast of a ship or other support upon which my device is mounted. It is to be understood that the invention is not limited in its application to a ship, but on the contrary, it may be used on observation towers with equal efliciency. In both figures 11, designates a cage, that is mounted upon the support 10, which may be formed and constructed of any light but durable material and of. sufficient capacity to accommodate one or more observers. Y
Within the cage 11, is a stand 12, on which is arranged ainagnifying-mirror 13, the diameter of which maybe varied consistent with the varying circumstances- Above the magnifying-mirror 13, the support 10 is provided with an inverted sub'- stantially cone-shaped structure, upon which is secured a concave,reflecting mirror 14, which if necessary,"may be raised or lowered by turning the entire structure holding the concave mirror, the center of said structure being threaded so as towork upon a limited distance of the support 10 that is screw-threaded. The higher the reflecting mirror 14 is raised, the Ygreater will be the radius of the sea that will be discernible in the magnifying-mirror 13, and the lower the mirror 14 is moved on the support 10, the more radius of the sea discernible in the magnifying-mirror 13 will be decreased.
. ln damp or foggy weather, the glasses may be kept clear by automatic glass-cleaners not shown in the drawings.
Above the mirror 14 is arranged a top 17, which carries curtains 18 which when the instrument is not in use, may be lowered so as to conceal'both mirrors, and protect the observer.
In the cage 11 is a push-button, which connects an electric signal, which is shown at 20, and a speaking-tube 19, so that the observer may instantly notify and communicate with the proper official. In operation the magnifying-mirror 13 is ever in full view of the observer, so that as soon as a submarine, ioating-mine, etc., appears within the radius embraced by the mirror 14 such image will be reiected by the mirror 14 to the mirror 13, such as indicated by the dotted lines in Fig. l. The observer may then notify and communicate with the properoflicial, by means of the electric signal and the speaking-tube.
ln Fig. 2, l have shown a slightly modied form of my invention. ln this form, the reflecting-mirror is designated by the numeral 21, and is also concaved, with its top-end sufficiently broadened, so as to reiect images as indicated by the dotted lines Y Ont-o the magnifying-mirror 22. The magni fying-mirror, (which is the same in both figures,) is here shown as graduated by very fine lines running at right angles to each other, their purpose being to assist the observer in locating the distance the reflected` strument useful at night or on very dark days. The size of the cage may be according to the varying conditions.
Suitable means for reaching these cages may be provided, such as rope-ladders, etc.
Communication -is established between the observer in the cage 11, and the search-light operator in the cage 24, by means of an electric signal and 'speaking-tube, constructed in the same manner as that described for communication between the observer and the proper'ship oiiicial.
The larger the instrument is made, the greater its radius.Y f
Having thus described my invention, what is claimed is:
l. A submarine detector comprising in combination With a support, a basket arranged on said support, a horizontally disposed mirror on .said support, and a substantially vertically disposed reflecting mirror above said horizontal mirror, said last named mirror being adapted to reflect images Within a given radius of said support onto said first named mirror.
2. A submarine detector comprising in combination with a support, a basket arranged on said support, a horizontally dis- Y posed mirror on said support, a substantially vertically disposed reflecting mirror arranged on said support above said horizontal mirror, a top portion arranged above said reflecting mirror; said second named mirror being adapted to reflect images Within a given radius of' said support onto said first named mirror.
3. A submarine detector comprising `in combination with a support, a basket arranged on said support, a horizontal magnifying mirror on said support7 a vertically disposed reflecting mirror arranged Vabove said magnifying mirror, a casing positioned on said support above said reflecting mirror, and said casing being provided With a series of radially disposed Windows substantially described.
