IMPROVEMENT IN' SHIPS RUDDERS.

Zo all whom it may concern.'

Be it known that we, THOMAS F. GOODWIN, ED- WARD OOMTED GooDw1N,aud CHARLES E. G01N, of the city, county, and State of New York, have invented a new aud improved Ships Rudder; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- A Figure l represents a side view, partly in section, of a ship to which'our improved rudder is being attached.

Figure 2 is a side view of. a ship provided with our improved rudder.

Figure 3, is a detail horizontal section of our im'- proved rudder, the plane of section being indicated by the line a: x, fig. 2.

Figure 4 is a detail horizontal section of the same, the plane of section being indicated by the line y y,

Similar letters of reference indicate corresponding parts.

This invention relates to a new sectional, removable rudder, which can be used onall kinds of lmarine vessels, from the smallest row-boat to the largest steamer, and which is so arranged, that it can be easily applied and repaired.

The invention consists in providing the sectional blades which constitute the rudder, with devices for fastening the same to the rudder-post.

This device consists of a pin pivoted to one end of the section, and fitted through a hole in the post, and of a clasp secured to the other end of the section, and locked around the post, as will be hereinafter more fully described.

A, in the drawing, represents the stern of a ship of suitable construction.

B is a tube fitted vertically through the vessel, as

shown in iig. l, and firmly and securely fastened in the same.

C is a metal post, or shaft, fitted through the tube, or case B, and resting with its lower end on a shoe, D, as in iig. 2, and with a shoulder, c, formed on it, upon a shoulder, b, of the tube, or upon the upper end of the tube.

Betweenthe shoulders a and b, may frictionrollers,

or spheres be interposed, to facilitate the turning of the rudder-post C.

The post C has, ormay have two or more perforations c c, indicated by dotted lines in g. 1, and a recess cut into it at the end of each perforation c.

It is also notched, as at el d in fig. l.

E E are the sectional wings, or blades, which, when attached to the rudder-post G, as in iig. 2, form and complete the rudder.

Two or more such wings may be used on one rudder.

They are removable from the post, and can be easily attached to the same.

To the lower part of each' section E, is pivoted a pin, e, by means of a pivot, j, as shown in figs. 1, 2, and more particularly iu iig. 4.

To the upper part of each section, is fastened in suitable manner, a clasp, g, which consists of two parts that are hinged together, as in iig. 3, the free part being perforated, so that it can be fitted over and around apin,

or staple, h, that is fastened to one face of the section,

as is also shown in lig. 3.

The pin e of each section is fitted through one of the holes c, and the clasp g around one of the notched parts l of the post, and thus the section is fastened to the post.

A rudder constructed like that hereinbefore described, can be originally arranged on a ship, as in g. 2, and will then be very useful and valuable, as in case a wing, or the whole rudder breaks, the injured part can be easily replaced.

The sectional rudder may, however, be carried as safety rudder on a ship which is provided with an ordinary rudder, as in fig. l.

In this case, the tube B is provided, and the shoe D made to project, as shown, and the post C can be let down whenever the original rudder G should be broken or injured.

The rudder can be secured in the following manner to a ship which is afloat:

. The post (l is by suitable tackle, suspended from a boom, F, and is let through the tube just far enough that its lower end may project, as in fig. l.

The lowermost section E, which is suspended horizontally by suitable tackle, and the pin e of which has been swung to project from the lower edge of the blade, is then by means of guy-ropes i i, brought towards the post, so that the pin' e can be inserted in the lowermost perforation c, as in g. 1.

This is done, as shown, above the water-line.

The post is then lowered still further, and the wing E is swung up, and secured by means of the clasp g.

The'post being still further lowered, the pin e ofthe second sectionban be secured, 85e., until all the sections are secured.

It will be noticed that all the sections can he secured above the water-line, and without much trouble.

We claim as new, and desire to secure by Letters Patent- The sectional blades E E, which constitute a rudder, provided with pivoted 'pins e, and with clasps y, and locking-devices h, substantially as and for the purpose herein shown and described.

THOS. F. GOODWIN. EDWD. OOMTED GOODWIN. O. E. GOIN.
