DIVING-RUDDEB GEAR FOR SUBMA RINE BOATS.
Specification of Letters Patent. PatentedDeo. 25, 191 7.
Application filed September 16, 1916. Serial No. 120,442.
To all whom it may concern:
Be it known that I, HAROLD M. De GRAW, a citizen of the United States, and a resident of New London, in the county ofNew London and State of Connecticut, have invented certain new and useful Improvements in Diving-Rudder Gears for Submarine Boats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention provides a novel and exceedingly simple operating gear for the diving-rudders of submarine boats.
According to the invention, each divingrudder is provided with a rudder shaft which is inclined to the plane of the rudder in such manner that turning the rudder shaft' through about 180 will swing the rudder from the extended to the retracted position, while slight angular movements of the shaft about the extended positionAwill s a result, universal joints or the like are dis pensed with; and yet each rudder may easily be retracted, extended, or tilted for steering.
The invention will be most clearly understood from the following description, taken in connection with the accompanying drawings, of which Figure 1 is a top plan view of a portion of the bow of a submarine boat equipped with the improved diving gear; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a perspective looking to the right of Fig. 1; andFig. 4 is a side elevation of a bow rudder when extended, certain other locations of the rudder being shown in broken lines.
The general arrangement of the divingrudders with respect to the hull of the boat is shown in Fig. 1, from which it will be seen that when the rudders 3 are extended they project horizontally on opposite sides of the boat, and when shipped or retracted into inoperative position they lie flat against the inclined sides of the superstructure 4 which overlies the hull 5 and are nested in pockets 6. In this case the diving-rudders are shownat the how; but they may be,ap
lied at the stem or elsewhere, as is well on an inclined pintle or shaftv 11 mounted in suitable bearings 12 and 13. The outboard end of each inclined shaft 11, which projects beyond the superstructure, has secured thereto one of the rudders 3. The shaft. bearings 8 and 12 are carried by a. base .14, anchored to a foundation 15 suitablyfixed in place ontopof hull 5. The shaft bearings 13 are supported by the superstructure 4. The shaft 7 is preferably inclined as illustrated, in order that at its rear end it maycarry an operating handwheel or the like (not shown) locatedinside the hull 5. V The parts as adjusted in Figs. 1 and? show the rudders extended with their flats horizontal. The rudders are now in operative condition, but they will act merely as steadying devices forthe fore part of the boat whenthe latter is so balanced and trimmed that the rudders are submerged. The rudders have been brought tothis ex,- tended positionby means of the rotation of the single operating shaft 7, in the direction of the arrow 16. A-slight rotation ofthe same operating shaft will now tilt the rudders 3 forward or aft, as shown at 30 and 40 in Fig. 4, to impart in the well known manner adownward or upward inclination to the bow during propulsion of the boat The fact that the tip of each rudder has .a slight forward or aft movement when the rudder is tilted does not interfere at all with successful steering. To return the rudders to shipped position,- .the only operation necessary is a rotation of the shaft 7 in a. directionopposite to that of arrow 16. Thus, in everyfcase, and for all adjustments. only the singleioperating shaft 7 is employed. During the upward and inward sweep of a rudder 3 to its shipped position therudder in succession assumes the locations'50, and 70 asshown in Fig. 4. During the downward and outward sweep of the rudder to its extended position it of course assumes in succession the locations 70, 60 and 50. As willbe seenfrom a comparison of Figs. 1 and 4, some-point 3 on the rudders edge shaft engaging both Worm-Wheels and r0- versely of the boat and inclined downwardlliy h 1 f tatable to move t e rudc ers mm a reand toward each other, a rudder fixedly 0 set from each shaft adjacent to its outboard end and arranged at an angle to the axis of its said shaft greater than a right angle, a pair of Worm-wheels one fixed on each shaft adjacent to its inboard end, and a Wormsteering.
In testimony whereof I atfix my signature.
HAROLD MASON DE GRAWV.
