Description
Patented Mar. 10, 1931 UNETED STATES FRANK REBL, OF RAVEN ROCK, NEW JERSEY STABILIZING RUDDER Application led November 3, 1928. Serial No. 317,034.
The object of this invention is to provide simple and effective means for permitting small power boats to ride evenly and steadily over the surface of ordinarily rough water 5 unperturbed by the waves.
Another object of the invention is to provide lateral stabilizing fins attached to the rudder of the boat in such a manner that the maximum power delivered to the water by the propeller is exerted thereon so as to steady the boat as well as to prevent the stern of the boat from being depressed due to suction.
A still further object of this invention is to provide lateral stabilizing fins which are adjustable as to forward inclination so as to permit a maximum efliciency to be attained regardless of the type of boat said stabilizing apparatus is used upon. j
A still further obj eet of the invention'is to provide vertical stabilizing fins located ap'- proximately amid-ships of the boat, one at each side, so as to prevent skidding when making a sharp turn.
My invention is clearly illustrated in the annexed drawings in which similar characters of reference refer to Asimilar parts throughout the several views.
Figure 1 is a longitudinal elevation of the boat.
Figure 2 is a rear view of the rudder showinfr the lateral stabilizer.
Figure 3 is a cross-sectional view of Figure 1 on the line 1 -t.
Referring to the drawings, Figure 5 represents the hull of the usual small speed boat which is driven forward by means of the propeller shaft 6 and propeller 7. The boat is steered by means of the rudder 8 attached to the rudder post 9 in the usual manner, the rudder post being capable of turning in the bearing struts 10. 11 represents the tiller rod which is grasped by the hand or other means in steering the boat. Attached to the vertical rudder 8 by means of bolts 12 are Vlaterally projecting ins 13. These fins 13 are capable of a slight forward or rearward inclination as will be readily understood owing to the slots 14 in the rudder. In operation it should be readily understood that ordinarily, without the lateral stabilizing fins,
the stern of the boat will sit down in the water causing the boat to eventually pop up and down with each wave, incidentally retarding the speed to a considerable extent. vWith 'theuse of these lateral stabilizing fins, the
stern ofthe boat is buoyed'up due to the hydroplane effect thereof, effectively preventing the aforementioned objections. In addition, these stabilizing fins permit the boat to make a hair-pin turn as, when the boat banks during the circling movement, the stabilizing fins will alsov prevent the boat from'turning over. It will be noticed thatV the fins project from the rudder at a slight upward angle so as to obtain the maximum resistance to turning over when making a sharp turn. To prevent the boat skidding and to provide better the planes for adjustably clamping said planes to the rudder.v Y j Signed at NewV York` in the county of Bronx and Stateof New York this 2d day of Y November, A. D. 1928.
