YACHT-RUBBER.

SPECIFICATION forming part Of Letters Patent N O.' 71 5,176, dated. December 2, 1902;

Application filed April 4, 1902. Serial No. 101,325. (No model.)

To all whom it may concern:

Be it known thatl, GEORGE W. SWAN,acitizen of the United States, residing at Toledo, in the county of Lucas andS tate of Ohio, have invented certain new and useful Improvements in Yacht-Rudders; 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 ap pertains to make and use the same.

My invention has reference to a rudder for sail-yachts, and has for its object to provide a rudder the blade of which will at all timestake a position near the vertical plane.

In carrying out my invention I provide means whereby the rudder-blade is turned upon the rudder-post as an axis, and the same is also turned upon an axis at an angle to the axis ofthe rudder-post. l

. It consists in the novel arrangement hereinafter shown, described, and claimed.

In the drawings, Figure 1 is a side elevation showing my improved rudder as applied to the hull of a yacht. Fig. 2 is an elevation of the stern of a yacht to further disclose my invention.

Referring to the parts, 1 indicates the hull of a yacht, and 2 the rudder-post passing upward through the hull in the ordinary manner.- The lower end of the rudder-post is pivotally supported at 3, and 4 is an ordinary tiller for turning the rudder-post.

5 indicates the rudder-blade, pivotally mounted at the lower end of the rudder-post, so as to turn upon an axis atan angle'to the axis of the rudder-post; Any suitable means may be employed for pivotally mounting the rudder-blade. In the means shown the inner end of the rudder-blade is in the form eta casting 6, havinga central perforation to. re-

ceive a bolt 7, secured in the lower end of the rudder-post, upon which the blade turns.

' The upper end of the casting 6 is providedv with a segmental gear 8, adapted to engage a segment of a gear 9, rigidly secured to the hull of the yacht, and the same immediately. adjoins the rudder-post. It will be apparent that as the rudder-blade is turned upon the rud'derpost as an axis the same will also be turned upon an axis at an angle thereto. This arrangement will maintainthe rudderblade in or near the vertical plane, even though the yacht is sailing on her beam.

This is readily apparent when it is remenh bored that the rudder-blade is made to assume a position toward the low side of the yacht in sailing. The turning of the rudder-post will cause the rudder-blade to also turn upon its axis at an angle to the axis of the rudder'post to assume a position in dotted lines a, Fig. 2, or a position in proximity thereto. In this figure the altered position of the hull when leaning is shown by the water-line m as, the water-line when the yacht is on an even keel being indicated by the line y. j

From the foregoing the advantages and utility of my invention will be apparent.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a rudder, the combination withthe rudder-post, of a rudder-blade pivoted thereto at an angle to the axis thereof, and means for turning'the rudder-blade upon its angular axis simultaneously with the turning of the rudder-post.

2. A rudder for sail-yachts comprising a rudder-post, a rudder-blade pivoted at the lower end of the post, a segmental gear upon theblade, and a segmental gear secured upon the hull of the yacht adapted to engage the gear upon the blade, as shown and for the purpose set forth.

In testimony vwhereof I hereunto affix my signature in presence of two witnesses.

GEORGE W. SWAN.
