To all whom it may concern: 7

Be it known that I, WALFRID S. EKLUND, a citizen of the United States, residing at Donner, in the parish of Terrebonne and State of Louisiana, haveinvented certain new and useful Improvements in Means for Steering Boats; and I do hereby declare the following to'be a full, clear, and exact'description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to means for steering boats and has for one of its objects the provision of a device of this character, which may be readily applied to the bow of a boat, and which will cooperate with the ordinary rudder on the stern thereof to permit of turning the boatin asmallspace and whereby the boat may be quickly turned from a straight course or run in a zigzag path providing means especially adapted for combating submarine boats.

Another object of this invention is to provide an auxiliary rudder mounted on the.

bow of the boat and adapted to be actuated by a fluid pressure means and which cooperates with the ordinary rudder on the stern in steering the boat.

A further object of this invention is to provide a pair of cylinders having pistons therein, which are connected to the auxiliary rudder and are alternately actuated by fluid pressure to turn or move said rudder in either direction.- V

A still further object of this invention is the provision of means for' steering boats of the above stated character, which shall be simple, durable and eflicient, and which may bemanufactured and sold at a comparatively low cost. a b I With theseand. other objects in view as will become more apparent as the description proceeds, the invention consistsin certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed. a v b For a complete understanding of my invention, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 1s a plan view partly in section of a means for steering boats constructed in accordance with my invention,

Fig. 2 is a side elevation of the same, Fig. 3 is a plan view of an indicator, Fig. 4 is a side elevation of a four-way valve applied for controlling the fluid pressure to the cylinders of the device.

Referring in detail to the drawings, the numeral 1 indicates a frame, which may be of any desired shape or configuration, but preferably of the shape as shown in Fig. 1

having a reduced end 2 and an enlarged end 3. The reduced end 2 of the frame 1 is bifurcated to form a pair of relatively spaced arms 4, in which are formed hearing openings to receive the .post 5 of a rudder 6, the post 5 being held within the hearing openings of the bifurcated arms 4 of the frame by a nut 7 or other suitable fastener. The frame 1 is secured to the bow of a boat 8 as shown in Fig. 1, so that the post 5 is disposed vertically and is forward of the stem.

,The enlarged end 3 of the framel is bifurcated to receive. a double segmental drum 9, which is journaled on a shaft 10 vcarried by the enlarged end 8 of the frame. A driven drum 11 is secured to .the post 5 ears 16 are carried by the driven drum l1 and have connected thereto, a clamping member 17 by bolts 18, which engages and forces the convolutions of the cable 12 into a groove 19 in the driven drum 11, thus preventing the cable 12 from slipping upon said driven drum. p

The frame 1 is provided with a downwardly offset portion 20 having secured therein, cylinders 21 and 22 by fasteners 28. Pistons 2 1 are slidably mounted within the cylinders and are connected to oppositely disposed arms25 of the segmental drum 9 as shown at 26 by connecting rods 27. The

pistons are adapted; to be alternately actuated within the cylinders by fluid pressure means, which will be hereinaftermore fully" described' for moving or turning the seg- V-mental drum 9 in either"direction,whichv 'will causethe driverr'drum 1l"to"turi 1"in either direction, moving the rudder 6- 1n correspending direction to facilitate the steeringo-fthejboatfibythe bow and whichis adapted to cooperate'wit'h an ordinary rudder, (not shown) placed"upon thestern or, the boat, wherebya steeringmechanism ingmembers- 31 that aresecured to-th'e-bow is"p rovi ded' forthe boat, whichwill "cause" a I said boat to befv'er'y'sensitweto the-steeringpower-thereof.

a Therudder 6 isgprovided with the usual reinforcing plates" 29, which are apertured to receive the loopedportions ,30 of fastenof' the boat by'fasteners 32. The-flooped portions extend around the stem 5 within" the" rei'nforcingmemb'ers 29 1 as clearly S awn iniFig: 2.

While I have shown and described I the preferred vembodiment of'my invention, it

will be unders'toodr that minor changes in construction, a combination and arrangement offpartsfniaybe made without departing from the-spirit and scope of the invention asclaimed.
