TO ALL WIIOM IT MAY CONCERN:

Be it known that I, IVILLIAH IT. CLARK, of Chester, in the county of Middlesex, in the State of Connec` tient, have invented a new and improved-Mode of Hanging the Rudder of Boats and Vessels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The-nature of my invention consists in providing the stern of a boat or vessel with a metal plate, having a groove enlarged inwardly, which groove is to receive a corresponding tongue, to which the rudder is permanently hinged, thereby hanging the rudder; and also in providing the tongue with extensions for hanging a. balance rudder.

To enable others skilled in the art to make and use my invent-ion, I will proceed to describe'its construction and operation.

In place of the devices now used for hanging ruddcrs'I attach a metal plate having a dove-tailed groove, or a groove enlarged inwardly, inte which groove I fit a corresponding metal tongue, to which the rudder is permanently attached by any suitable hinge.

Figure 1, of the accompanying drawings, is the representation of a-rudder hung according to my invention. B represents the stern of a boat to which a metal plate, IP, having a dove-tailed groove, g, is represented as attached by screws passing through the extensions in the plate, represented at e e e in Figure 2, which is a representation ofthe plate detached. T represents a tongue, dove-tailed to correspond with the groove gin the plate, and provided with strap-eyes, shown at S S S S, through which the straps a a pass, and are attached to the rudder R, permanently hiuging the rudder to the tongue, whereby it follows that to unship the rudder, the tongue must be withdrawn from the groove in the plate upwardly, the groove being slightly enlarged upwardly, as shown, and shipped by the reverse process. I insert a pin in the tongue near the top, which enters the recess provided for itin thetop of the plate, and fixes or limits the distance the tongue may enter. The pin is marked o in Figure 3, which is a representation of the tongue detached. Figure 4 is the representation of the tongue provided with extensions for a balancefruddcr, which are marked n n. The extensions upon the tongue, by being carried out, will enable the rudder to be hung in the centre to balance it, if desired. When the head of the rudder to be hungrships through a rudder port, of course the tongue cannot Wholly be entered from the top of the groove; in that case, instead of making the corresponding enlargement or dove-tail of the tongue continuous, I make it in sections, and construct the plate with corresponding ports or openings to receive them, from which the dove-tailed sections enterthcir corresponding grooves in the plato instead of being passed in from the top of the groove.

With the arrangement heretofore known and used for hanging rudders it has been more or less diiicult to readily ship the rudder of a small heat, in 'consequence of one of the hinges being below the surface of the water. This makes it diicult to eiect the connection of the hinges when the Water is rippied or not clear, and especially diicult in the night, when the wavesare striking against the rudder, and the connection is not sure in rough weather, while-the liability of the rudder to get unhingcd by contact with thc shore, and by various other causes, makes it necessary that it should be unshipped when not in use. By my improved mode of hanging, the rudder may be readily shipped under all circumstances, and is .securely hung. Y

What I claim as my invention, and desire to secure by Letters Patcnt,is

The plate P and tongue T, incombination with the hinged rudder R, substantially as herein described aud for the purpose specified. i
