29493. "W. N. Clark's rudder-hanger." (Patented September 3, 18G7.) 

 James B. Clark, Chester, Conn. 



"Advantages claimed for this hanger: To ship the rudder one has only 

 to enter the tongue (which has the rudder already attached) in the 

 grooved plate from-the toj) just far enough to get it steady, and then let 

 it down, when it will go to its jilaco without further care. Hence arises 

 the first great advantage which tliis hanger possesses over the old way, 

 viz, the ease and dispatch with which the rudder can be shipi^ed under 

 all cii'cumstances. 



Every boatman knows the trouble he has been to, at times, in trying 

 to ship his rudder, while in a seaway, in the dark, or in muddy waier, 

 when the eyes in the boat could not be seen; often being obliged to 

 reach down with his hand to get the lower pintle entered. 



From the quickness Avith which the rudder can be shi^jped, in any posi- 

 tion of the boat, and under any circumstances, and its security when 

 shipped, it must recommend itself for all life-boat purposes, where, in 

 case of an emergency, time is of vital importance. 



Another advantage is that with this hanger the rudder cannot of itself 

 unship as has of^eu been the case with the common hanger, when the 

 boat has been left for a short time and the tiller Avorked out, thereby 

 leaving the rudder free, by striking the bottom or anything .sulficient to 

 raise it three or four inches, to unhinge and Uoat away. As will readily 

 be seen, this cannot get away until the rudder has risen the whole length 

 of the tongue, which, of itself, wouM never li.ippeu. 



Again, with this hauger the rudder can be shipped and imshipped 

 while under full sail, thus making it very convenient for fishermen or
