IMPROVEMENT IN BOOM AND RAFT RUDDERS.

Specification forming part of Letters Patent No. 138,760, dated May 13, 1873; application filed september 9, 1872.

To all whom it may concern:

Be it known that I, LEVI W. POND, of Eau Claire, in the county of Eau Claire and in the State of Wisconsin, have invented certain Improvements in Boom and Raft Rudder, of which the following is a specification:

Natie-rc and Object of the Intention.

My invention is a rudder to be placed on the side of a boom, and so arranged that when set in one direction will throw the boom across the river, and when set in the other direction will Swing the boom open rapidly, or when set in front of a raft will .turn it in either direction, as it'may be set. The lines for setting the paddle in either direction are on board the boat, and when the raft is wanted to be Set in one direction pull on the line reaching to one end of the rudder, and when to the other side pull on the rope running to the other end of the rudder, and thus save the expense of men on the front end of the raft to steer it with oars or sweeps. These rafts are pushed through the water by a steamboat in their rear. The bow of a boat is seen in the drawing pushing the raft along, with the ropes running from the rudder back on board ot' the boat.

General Description.

A, the boom stick or raft; B, the standard to which the rudder is hung by the middle; O, the rudder; D7 a piece fastened to the end of the rudder for the water to catch on, throw the rudder open or in a contrary direction; E, another piece on the other end of the vrudder for the same purpose as the one on the other end of the rudder 5 F, ropes to open and close the rudders; G, a piece to which the boom is hung; H, the runner through which the lines from the rudders run on board the boat. The boom is representedswun g back, and the river is left open for anything to pass. The rudders are swung back, and the current has pulled the boom out of the way of anything. The

dotted lines show the boom swung ont against the current to sheer the logs across the river into the side boom. The rope F is pulled in and the front ends of the rudders -are pulled against the boom, and the water, strikin g against the rudders, runs the boom across the current. The water presses lthe hardest against the outer end of the rudders, so that when the rope is slacked up thev rudders will fall ott' from the boom-end. Thewater, catching against the piece D or E, swings the rudder back. On the raft two lines to each rudder is wanted, so as to tilt either end of the rudder inward, as may be desired. These rndders will throw the bow of the raft in either direction, as the rudders may be turned, and the raft may loe steered on board the boat as well as on the raft.

Claim.

I claim as niy invention- Rudder G, with end pieces D and E, in conibination with Stationary supportB and rope F, substantially as described.
