Specification of Letters Patent.
Patented Dec. 10, 1918.
Application filed April 30, 1917, Serial No. 165,468. Renewed April 27, 1918. Serial No. 231,276.
To all whom it may concern:
Be it known that I, HARRY W. YOUNG, a
citizen of the United States, residing at This invention relates to ships rudders in' which the rudder shaft or post is mounted in a bearing tube, and the invention relates more particularly to this tube, the object being to provide a novel and improved supporting means therefor which enables it to be set vertically irrespective of the angle of the vessels bottom.
The object stat-ed is attained by means of a combination and arrangement of parts to be hereinafter described andclairned, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.
In the drawing- Figure 1 is a longitudinal section showing the application of the invention;
gig. 2 is an inverted plan View thereof; an
Fig. 3 is a longitudinal section showing a' slight modification.
Referring specifically to the drawing, 5 denotes the bottom of a boat at the stern thereof, and 6 shows a fragment of the shaft or post which carries the rudder. This rudder shaft or post is supported in a bearing tube 7 positioned vertically in an opening in the boat bottom and depending a suitable distance therefrom. On the boat bottom is secured a housing 8 which incloses the dc pending portion of the rudder shaft. This housing has an oval base outline and is gradually tapered to frusto-conical form, the contracted portion of the housing having an internal seat 9 for an abutment 10 mounted on the bearing tube. This abutment is substantially semi-spherical and the seat is correspondingly formed, in view of which a ball-and-socket or flexible. joint is had between the housing and the bearing tube inclosed therein. On the'bearing tube, above the boat bottom is threaded a nut 11 by which the tube may be drawn upward to firmly hold the abutment on the seat, thereby preventing leakage of water into the housing. By the ball-and-sooket joint, the bearing tube can be readily positioned vertically irrespective of the angle or slope of the ing therefrom; of a housing mounted on the boat bottom and inolosing the depending bearing tube, and a flexible connection between the housing and the bearing tube.
3. The combination with the bottom of a boat and a rudder post bearing tube depending therefrom; of a housing mounted on the boat bottom and inolosing the depending bearing tube, said housing having a curvilinear seat, and a correspondingly shaped abutment on the bearing tube engaging said seat.
4. The combination with the bottom of a boat and a rudder post bearing tube depending therefrom; of a housing mounted on the boat bottom and inolosing the depending bearing tube, said housing having a curvilinear seat, and a correspondingly shaped abutment on thebearing tube engaging said seat, and means for clamping said abutment to the seat. r
In testimony whereof I afiix my signature.
HARRY W. YOUNG.
