Application filed March 13, 1915. Serial No. 14,297.

To all whom it may concern .1

' State of Be it known that LRLEYNOLD JANNEY, a

citizen of the United States. residing at erning-apparatus, the object of the invention being to provide means of this character'which is'comparatively simple in construction and effective, positive and certain inaction] An apparatus of this nature can be employed with utility in many different connections; As one illustration of a number'it may be incorporated in or form part of a submarine, and in this particular case acts to automatically control the submergence of the vessel.

In the drawings accompanying and formng part of the present specificatlon, I show 'in detail one of the several convenient forms of embodiment .of the invention,

which I will set forth in the following description to enable those skilled in the art to practise the invention. 7 myself to this disclosure; 1 may depart therefrom in radical respects within the scope oftlve invention defined by the claims t following said description. As a matter of fact While the'apparatus is of prlme utility when used in conpmction with or forming 1 part of a submarine, it can be employed.

with equal advantage in other connections.

Referring to said drawings: Figure 1 is a sectional view of a submarine combined with pressure-controlled governing-apparatus' involving the invention. Fig. 2 is a de tailview of a portion of the apparatus with. the parts in different positions from those shown in Fig. 1 and on a scale larger than that of said Fig. 1.

Like characters refer to likepartsin both "view's.

Certain of the elements of the apparatus as will hereinafter appear are duplicated which is advantageous in the particular, use shown to which said apparatus is put. This duplication may not always be necessary.-.

In Fig. 1', Irhave shown a submarine-2m the stem or how and stern of whlch respectively are represented as mounted" depth-governingplanes 3 ends which are I do not limit' horizontally disposed. when in the neutral posit on as shown n sald view. 'As'illustrated said planes are fastened respectively to suitably mounted shafts 5 and 6. In thehull of the submarine 2 is mounted a suitable primary controllmg member such as the longitudinally movable rod or bar 7 which cooperates with duplicate control mechanisms, one of which for example that.

on the right in Fig. 1. willbe, d scribed in inferred, precisely to the other. One of the control mechanisms is preferably located at or near the bow of the vessel and the other at or near the stern. I

Referring now in detail to Fig. 2 the control mechanism there shown comprises an actuating device suchasthe hydraulic variable speed gear 8 and suitable operating means therefor suchas the electric mo-- shaft of the hydraulic variable speed gear 8. The hydraulic variable'speed gear 8 is provided with the rotary control shaft 16 which operates the regulator in the A-end. \Yhen said shaft 16 and regulator are in their neutral positions as shown in Fig. 1, the shaft 12 will be stationary. The control shaft 16 through suitable means, moves this regulator oppositely from its neutral position, the speed of the shaft 12 progressively increasing as the parts in question move from their neutral positions and the rotation of the shaft 12 corresponding with the direction of movement of said regulator and control shaft. 'lhesha-ft ill and hence the shaft 10 are continuously drivenJ The hydraulic variable speed gear briefly described together with its operating motor are both in themselves old, being likethe corresponding parts shown in Letters Fat 105 17 to the outer end of which one end of a follow up link as 18 1s plvoted, the -oppo- 1 1'0 Patented June 20, 19 16.

- I o detail, this description applying as will be site end of said link bein likewise connected to one end of the floating lever 19. The

opposite end of this floating lever 19 is pro-- vided with a segmental rack 20 in mesh with' the plIllOIi- 21 ri 'd with the control shaft 16. One end the link 22 is pivoted to the floating lever 19 between the I rigid with the hull of the submarine 2 open.-

ing into the sea preferably near the bow and stern of the vessel. The pistons 25 oocupy positions which differ in accordance with the pressure of-the water thereagainst, the greater the pressure the greater will be the amdunt' of inward movement of the pistons. This pressure as will be obvious increases with the increase in submergence of the submarine. The pistons 25 constitute suitable pressure-controlled devices. As may be inferred they are movable inward by the pressure of the water and outward by springs 27 backing the same.

Any desirable means may be provided for operating the rod or bar 7 longitudinally. The meansshown'for this purpose will now be set forth.

The rod has between its ends rack teeth .28 in mesh with the p inion29 fastened to the-shaft30 furnished with an operating 'Vhand lever 31 equippedwith a suitable pointer to traverse the scale 32. The scale 32 in the case of a submarine is a depthscale.

In Fig. 1 all the parts are shown'as occupying their normal or neutral positions.

It Willbe assumed that the submarine is moving on the surface and that it is desired to submerge the same. In this event the hand lever 30 is swung over until the pointer thereon is opposite the predetermined depth on the. scale 32. -Referring now to Fig. 2 it will be clear that when the hand lever 31 is thus operated the primary controlling member 7 is moved from its neutral position toward the right, thus causing the floating lever 23 to swing to the right on its pivot with the end of the rod 24 as a center. The link 22, therefore, thrusts the floating lever 19 to the right so that the segment 20 thereof acting on the pinion 21, will turn the control shaft and therefore the regulator or tilting box in the A-end of the hydraulic variable speed gear 8 to effect the rotation of the shaft 12 andtherefore' of the shaft 15, the worm 14 rotating the worm gear 13 and -therefore the crank or plane .initial positions.

shaft 5, and therefore,the plane 3, the latter being tipped or swung downward and the degree of angular movement of the'plane 3 corresponding with thedegree of movement; of the controlling member or rod 7 and the lever 31. The plane, therefore, will be moved through an angle to secure the sub mergence of the submarine 2 toward a depth corresponding to the numberon the scale 32. In Fig. 2 the parts are shown in the positions they occupy just after the lever 31 has been thrown over. itvvill be under stood that when the lever 31 is'operated in such manner that the plane 3 is immediately tipped downward so that the submarine can descend in the direction of the desired depth. As the plane 3 begins to swing downward the crank arm 17 is moved to the right carrying in a corresponding direction the follow up link 18 which acting upon the floating lever 19,1'eturns the latter and hence the segment 20 forming a part thereof to the This brings the control shaft 16 to its neutral position and stops the shaft 12 and the parts 15, 11 and 5 connected therewith and holds'the plane 3 in an inclined position proportional to its position indicated by the hand lever 31.

Thus far two factors have governed the hydraulic variable speed gear, one being set into action by the primary controlling element 7 and the other by the plane 3; By the duplicate apparatus at the other end of the vessel, the plane =1 is tipped upward by the same movement of the lever 31. A movement of the hand lever 31 to the left would cause the plane 3 to tip upward and the plane 4 to tip downward. As the vesseb changes its depth a third and pressure governed element actsupon the control shaft- 16 to' modify the direction and speed of the branches of the levers 23 being moved inward and the lower branches thereof being moved outward, thus causing through the intermediate links 22 the movement of the floating levels 19 to reversing positions and acting on -the hydraulic gear 8 and intermediate parts in turn upon the planes 3 and 4 to restore said planes to horizontal positions or to' reversed positions if the prescribed depth should have been exceeded.

It is evident that the interaction of the several parts will result in bringingthe planes 3 and 4 to their horizontal positions and the control shafts 16 to'their central or neutral positions when the vessel reaches the depth indicated bythe lever 31 onthe scale 32. The description of theoperation has thus far referred chiefly to ,the downward movement of the vessel; but it is evident that the movementsof the hand lever 31 will cause the vessel to move upward or down- .vard according to the direction of movethe vessel independently operable 'Morement of the'vessel forwarder backward and according as the lever 31 is moved to the right or'left. g a 1 It isevi lent that the rod 7 or its equivalent may be in sections and another lever 31 or analogous means provided so as to .make the two sets of apparatus at each end of over, ,the two parts of the rod 7 'or the like may be adjustably united so as to produce any desired relative effects on the sets of apparatus, these effects being. controlled by the combined mov'en'ients of the lever 31 and the adjustable connection.

The operation of the combined arrange ments as shown in the drawings keeps the vessel on even keel during changes of depth. What 1 claim is: i
