ATTACHING RUDDERS TO BOATS.
SPECIFICATION forming part of Letters Patent No. 310,458, dated January 6, 1885.
Application filed August 520, 1884. (No model.)
To all whom ,it may concern Be it known that l, JOHN F. Munir, of Brooklyn, in the county of Kings and State otl New York, have invented certain new and useful Improvements in Attaching Itudders to Boats; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in devices for securing rudders to boats, particularly small boats, in which the rudders are usually removed when the boats are not in use, the object of the same being to connect the rudder to the stern-post of the boat in such a manner that the rudder can be easily and quickly placed in position, and will be free to rise and fall without binding or becoming wedged; and with these ends in view my invention consists in the parts and com binations ol" parts, as will be hereinafter de scribed, and pointed out in the claims.
In the accompanying` drawings, Figure lis a view in side elevation showing my improved attachment. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a vertical sectional view of the lower end of the socket and rudder-slide, and Fig. 4 is a detached view in perspective of the slide.
A represents a boat, to the stern-post B of which the metal socket C is secured. This socket, which extends from the keel to near the upper edge of the stern-post, is made of cast metal, and is provided with the inwardly-eXtending flanges a, between which the metallic slide E rests and moves. This socket is removably secured to the stern-post by screws, and is closed at its lower end by the removable block D, which latter forms the limit of downward movement of the rudderslide. This socket C and block D are further supported by the metallic plate F, rigidly secured to the keel of the boat, and projecting rearwardly and forming a seat for the socket and block. The flanges a of the socket C are parallel or approximately parallel with the stern-post ofthe boat, and sufficient space between these flanges and the body ofthe socket is left for the rudder-slide. The rudder-slide E, which is also made of cast metal, is slightly shorter than socket C, and is provided on opposite sides with grooves c, in which the flanges a of the socket C rest. The grooves c are slightly larger than the flanges ,to permit the slide to move vertically without binding, and the lower edge of the slide is preferably rounded or reduced in size,to enable the slide to be quickly and easily inserted in the socket. The portion of the slide which rests in front ot` the flanges is preferably provided with curved sides, and is smaller than the space between the flanges and the front wall of the socket, to enable it to move vertically without binding or becoming wedged when the rudder strikes an obstruction. The rudder-slide is provided with the rearwardlyprojecting perforated lugs d, to which the rudder II secured by the straps I and pintles.
By the use oi' the above-described attachment it is simply necessary to introduce the lower end ofthe rudder-slide into the upper end of the socket, (which isabove the water,) and then release the rudder, which settles down to its position. Heret-ofore in devices of this character the socket has been dovetailed, and the rudder-slide made of similar shape. Such a construct-ion is objectionable, in that, when the outer or rear end of the rudder strikes an obstruction, the rudder-slide,in stead of rising with, will be drawn outwardly and wedged between the undercut flanges of the socket. In my device the rudder,instead of becoming` wedged under similar circumstances, will be forced upwardly and carried out of danger.
My device is exceedingly simple in construction, is durable and efficient in use, can be applied to any and all boats, and can be manufactured and sold at a small initial cost.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent is* 1. The combination, with a single elongated socket constructed substantially as described, of the rudderslide slightly shorter than the socket, and provided with side grooves, in
which the auges ofthe socket rest, the perder, all of the above parts constructed sub- 1of forated lugs rigidly secured to the outer face stmitially as set forth. of the slide, for the attachment ofthe rudder, In testimony whereof I have signed this :mdablook closing the lower end ofthe socket. specification in the presence of two subscrib- 5 2. The combination, with the socket secured ing Witnesses.
to the stern of the boat, the block secured JOHN F. MUMM. Within the lowel` end ofthe soeket,and the plate W'itnesses: l secured to the keel and forming a seat for the GEO. FrDoWNING, socket and block, of the rudder-slide and 1ud C. S; DRURY. l
