PERISCOPE.
'/'o all whom it may concern:
Be it. known that l, VVinmau Naim1 How mi., a `citizen of' the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania. temporarily residing in London, England, have invented a certain new and useful Improvement in Periscopes, of which the following is a iin-ll, clear, and -exact description.
'lKhis invention relates to periscopes for use in submergible vessels of all kinds, and especially submarine torpedo boats.
Briefly stated, the object of the invention is to provide an instrument bv which a View of the entire horizon may be had by the occupant of 4the vessel a-t all times, when the ivessel is ruiming beneath the surface ot' the water with only the upper end of the instrument. projecting above the surface, and without requirinfr an adjustment of the inslrnment, as has'iiitherto been necessary, `in order to obtain a View in any given direction other than the Vone to which the instrument is set at the ltime.
With the instruments now in use, it is necessary for the steersman, or observer, to keep his eye ldirected upon the instrument, ruhe same as Iin looking through an ordinary field-glass, and to manually turn the instrument when it is desired to view the horizon in different directions. 'lhis operation is exceedingly disadvantageous, since it not onli: requires the observer to concentrate his cve directly on the instrument, but also necessitates the Imanual operation of the mstrnment to shift it, and this last is ac- I'om-plished with difficulty, owing to the iight-fitting bearings and stuffing-boxes in which the instrument is mounte ln order to overcome these objectionable features, I provide a rapidly revolving obr4erving tube, having the usual prisms or releer ors which are adapted to reflect to the haer-ver all 4objects at any point on the zon, whereby the opeaator is enabled to rve an fobject lying 1n any di ion wit'l .ion vto his vessel or approa :l from' an direction. This v. sts in a recision of aim ofthe at an hostie vessel, but also enel', coupants besides -the steersman. in observation f llc Op@ hns Specification of Letters Patent.

the vessel may station themselves to ohsert` in other directions, and thus it is possibi. to ascertain the approach of a vessel or ve sels from various directions.
VVitxh my arrangement, an image is i liect-ed into the vessel the same as in olla instruments, it being only necessary tor th observer to change his position in order it obtain a view in anv given direction.
The invention a so comprises certain pw culiar structural features and arl-magentan` of the operative ia-rts ot' the device, all will be described tull-y and then particularh claimed.
In the accompanying drawings, illnstrai ing the invention, 1n the several figures which like parts are similarly designan-d Figure 1 is a sectional elevation of the up per portion of a vessel showing the nn irovement in position. Fig. 2 is a vertica longitudinal section of the same, on a larger sca e. Fig. 3 is a diagrammatic View.
A designates a portion of the deck or conning tower or vturret of a submarine ve sel, in which is securely mounted a tubular casing or support B, which projects through the vessel to anv desired height, and is preterably provided with a land-rinUC, to pre vent ingress of water trough tiie openinir of the vessel through which the casing l# extends. Near the upper and 'lower rfndof the casing are arranged bea-ring-rings l). in which is mounted an observing tube l'l. having collars or flanges E, co-acting will] the hearing-rings I) bv means ot' interi-instal antitriction balls. which permit a free rn tary movement of the tube.
F and F' are. optical prisms or reflectors secured in any suitable manner at. opposite ends of the tube E, respectively, each prism having its reflecting face inclined at such an angle with the axis of the observing tub that an image ot' an external object receive( through the prism l", will be reflected down i wardly through the tube into the interior o y the vessel through .the prism F', for the in spection of the observer. In practice I ma f'iiacent to the face of the prisi a system of such lenses, t

By changin his position to either .side of the prism, an looking in the direction indicated by either of the arrows 2, he can obtain a view in either direction upon the horizon. Likewise, a view can be had of the entire horizon by simply walking around the instrument. f
ItV Will be understood that field glasses may be employed to look into 'the prism F', `to magnify-the object; and a separate range finder may also be used in connection with the periscope for vgetting the range of 'distant objects. l
From the foregoing, the advantages of my improvement will be readily apparent to those skilled in the art to which my in s vention appertains, and further statements as to its usefulness are thought to be unnecessar i l.
