To ALE WHOM ITMAY G ONGERN:

Be it known that I, ENRY H. P EMBER, of the city, coun-ty, and State' oF New York, have invented a new and usefullmprovement in Hanging or Applying Rudders to Vessels; and I do hereby declare that'thefollowi-ng is -a full, clear, and exact descriptionv thereof, which will enable others skilled in the art to make and use the same, referencebeing had to the accompanying drawinga'forming part of this specification.

This invention relates to :t new and improved mode ot' hanging rudders to vessels, as hereinafter fully shown and described, whereby' a rudder may be nnshippe'd-and shipped with far greater facilityr than hitherto, so much so as to admit of a rudder, in case ofv being damaged and rendered unserviceable at sea,being unshipped and drawn directlyu'p through the'rudder-port upon deck, (for the purpose of shipping a spare rudde1,) withont.the trouble and danger of lowering a boat and making chain or rope connections, with a view of drawing the rudder up atfthe other vside of the vessel. n

. Besides this advantage, the invention consists of the rudder being unshipped\vithout being lowered, the

'necessity'of which requires the vessel to' be in deep water, in order that the rudderstem may be drawn down ont Vfrom the rudder-port, `and hence, wheufa vessel lyingin port requires to have its rudder unsbipped for repairs,

it'is veryY often necessary to draw oil` intofdeep water in order to accomplish that end'. I n the accompanying sheet of drawingsA v Figure 1 is a side sectional viewot' the rear part or stern of a. vessel having its rudder hung or applied according torl'nyr invention.

Figure 2 a transverse vertical section of the same, taken in the line fr x, tig. 1. Figure 3 a horizontal section of the same, taken in the line y y, iig. 1.

Similar letters of refer-ence indicate `corresponding parts.v

A'represents the rear portion of a,- vessel, a beingthe stern-post, 1? the rudder, `and C the rudder-port.

(See more particularlyg. 1.) The rudder may be ofthe usual form or shape, but it is hungin a novel manner, as follows: The rear end of the keel D has a metallic extension, E, firmly secured to it, and this extension has an upright rod, F, firmly attached, said rod being parallel with thel stern-post a, and extending upward nearly to tbeilevel of the deck ofthe vessel, as shown in gf 1. The .rudder-B has its post CX made tubular, to receive a metal tube, c, the interna'l'diam'eter of the vtubebeing equalt'o the rodF, so that the latter may Afit inthe `former, the rudder resting on a metal bearing, (l, as shown 'in iig.' By 'this means the extension E is relieved of the weighto' the rudder. vClfhero'd F is stayed by metal braces or bars, e, which areattached to the sternpost a, and the tube c has ey esfattached`,which are fitted and work on the-rod F, said eyes having vertical slots g made in them, to admit oi' their, passing' c lo\ vn over the braces orbars e, the eyes, when the rudder is.

turned, turning between the braces or hars e. The Vrudder-post CX passesup through the deck of the vessel, and has a metal cap, L, secured upon its upper end. Thiseaphas'a flange, j, on its lower end, extending allarouud it, and an annular rim,j, on a c'ollar, G, bears' upon this ila-nge 1.', 'the' collar being bolted downvupon -doors H in the top of the rudderlport C, the bolts passing into the timbers of'the deck. This collar'- prevents the rudder from being thrown upward under the action ofthe se'a vorfrom other causes. The rudder-port()l has an opening, fc, extending vertically vthrough it. This openingis of -suihcient dimensions to' admit of the rudder being drawn directly up through the port, when` the doorsH are opened orraised. This will be fully understood by referring to g. 1. Th bottom of 4the opening. h has aport or door,`Z, which lis designed to keepout the water Vfrom the port. AThis port or door mayhave a cord vor chain attached, for the convenience of opening itfrom the-deck when the' rudder is to be unshipped and-raised.` Y

This invention admits of a metal rudder being used, if desired, the rudder-being cast with a hole or opening in it to receive the rod F, which admits'rot' its'tfurning on a centre,. as' the rudders' new in use. In this instance the rod F cannot be braced from the, sternfpost, but such bracing'is -not indispensablynecessary, as the rudder ie prevented from moving laterally owingto the-confinement pf 'its stem by the collar G.

i `Having described `lily inventiomwhat I clainias new, and' desire to' secure by Letters Patent, isi'- The collar conncction'withthe dang'ez'on cap'h of'rudder-postfCX, and the rod-F attached to the keel, all arranged'substantially in the maimer asand for the purpose set forth. y
