This invent-ion relatos to the dass of suhluarine boats wherein the bont is lit-tod with a compass for mpintaining tout@ when nnb merged and also with optical instruments or devices known as altiscopes, purine-open, Jac., which are designed to cnuhlo the steers man or observer in the vossol to ohsorvo surrounding obiectsifrom n point. considerably below the levl of the water.

In order that the observer may note the bearing, of the object of which he secs the unige through the eyepiece, the following means 'are employed:

Within the chamber C is a pinion 23, gearing with the wheel 19 and serving to transmit motion t.hroiiglishafts 24 and .25 and gear wheels 26, Fig. 3: to the hand or iointer 4 of iin indicator on the front. plate oi lier C.

This card may bc turned about over the face ol' the disk, but will he held by suitable frictional means in any position desired. (See Fig. 6.) 0n this card is a lulibers liuc or niark a, which when the iustruiiieiit has its optical tube so turned that. the up ier rctlcctor or iris-iii Il receives an image oliaii ohject wliici is directly ahead will he coincident with the pointer 4 of the indicator, and in the optical tube is a cross-wire w, which under the saine circumstances will be. coincident with ii vertical pliiiic piissiiier through the longitudinal axis of the bout. l`his wire divides thc tield of view into two e'quiil parts.'

Below thc chamber C is ii tclltalle-compass tl within the View ol the eye c of thc ohserver at thc e 'cpiece, aiidlielow this-couipiiss is iiiountci a suitable iiuwniljy'ing-lcns 3() iiiid a frietioniiily-hinged rcllictor Iii. cyc c' o1' the t-cersiniiii will he so situated iis to coiiiniiiiid the innige iii thc reflector 2H.

This invention is not concerned with any speci'iil means for drying the air, as it is not new to dry air and force. it through the optical tube of an altiseope provided with a pressure-valve at its upper end, This construction und ilisposit-ion of parts is intended to provide a station for the commanding otlicer or navigator, hereinbefore called the observer," and for an independent steersnian or helmsman. With this arrangement the commanding ofticer may Aperform the followin functions without changing his position: First, (a.) con the vessel when on the surface, awash, or sub merged, either through the usual sighting-i ortsof the conning-tower or b compass or.

y means of the optical tube; (g) search the horizon by means of the optical tube and take compass-bearings with the combined dummy compass and indicatorear, at the same time kee ing check u on t e compasscourses steeredJ by the in ependent. steezs man stationed at the lower steering-wheel; second, take charge of the actual steering of the vessel when lie so desires while cunning through the sightingorts by compass or through the optical tu e.

The Present invention relates to the means for steering the vessel or boat, as set forth definitely in the claims. The. other specific features shown herein form the subject-matter of copend ing divisions of this a lication, Serial Nos. 238,796 and $38,797. heee last nii-mcd features, which relate to the optical tube aud means for preventing condensation tot' moisture therein, are'illustrated and de` `scribed herein because of their close relation to the present invention and because they iirc constructively combined with the steerini,r devices in actual practice.
