Specification of Letters Patent.

Patented J an. 2, 1917.

Application filed September 12, 1916. Serial No. 119,717.

To all whom it may concern:

Be it known that I, NIELs J ANTZEN, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of WVashington, have invented new and useful Improvements in Boats Rudders, of which the following is a specification.

The invention relates to a boats rudder, and more particularly to the class of ships rudders and brakes.

The primary object of the invention is the provision of a rudder and brake structure for ships wherein the blades of the rudder and brakes are readily and easily placed in position and can be manipulated for the maneuvering of the ship to change or alter the course of travel thereof so that the same can take sharp turns or can move obliquely and at the same time the control of the ship to reduce the speed of travel thereof when the occasion requires is effected by the manipulation of the rudders.

Another object of the invention is the provision of a rudder and brake structure of this character wherein the same is of novel form so that the course of the ship will be positive for the guiding thereof in such course.

A further object of the invention is the provision of a rudder and brake structure of this character wherein the same are readily interchangeable from the bow to the stern end or vice versa and are so mounted to eliminate hinges, the said rudder and brake being coupled in a .novel manner to permit the self-locking thereof in position and is capable of operation for the maneuvering of the ship in its desired course.

A still further object of the invention is the provision of a rudder and brake structure wherein on damage thereto the same can be readily removed with despatch and a new rudder and brake placed in its stead or the damaged rudder repaired and thereafter conveniently replaced in proper position.

A still further object of the invention is the provision of a rudder and brake structure of this character which is extremely simple in construction, thoroughly reliable and eflicient in its operation, strong, durable and inexpensive in manufacture and installation.

Other objects will be in part obvious and ,in part hereinafter set forth.

The invent'on accordingly consists in the features of construction, combination of ele ments and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawings: Figure 1 is aside elevation of a boat showing the fore and aft combined rudder and brake structure in accordance with the invention; Fig. 2 is an enlarged fragmentary vertical longitudinal sectional view; Fig. 3 is a top plan View; Fig. 4 is a sectional view on the line t4 of Fig. 3; Fig. 5 is an elevation looking toward the aft end of the boat showing the manner of introduction of the rudder and brake therein; Fig. 6 is a fragmentary elevation showing the clutch coupling for the rudder the latter being re leased from the coupling; Fig. 7 is a fragmentary vertical longitudinal sectional view through the boat.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, A designates generally the body of a boat which is termed the hull and is formed at its bottom with the keel B as usual. In the fore and aft ends of the body A are formed framed openings O, each frame 10 thereof being designed for the mounting of the combined rudder and brake hereinafter fully described. Each combined rudder and brake comprises a blade 11 which, in this instance, is preferably of truncated elliptical shape and is reinforced, as at 12, to give strength and rigidity thereto. Each blade 11 is formed at opposite truncated ends with the clutch and pivot sockets 13 and 14, respectively, while mounted in each frame 10 of the opening at the bottom thereof is a pivot stud 15 which loosely engages in the pivot socket 14, while fitted in the said frame 10 at the top thereof for vertical sliding movement is a shaft 16 formed at its lower end with a clutch head 17 which is adapted for detachable engagement in the clutch socket 13 in the blade 11, and in this manner the latter is detachably mounted within the opening 10 so as to permit the convenient removal thereof with despatch or the placing of said blade therein, as will be obvious. On the upper end of each stem 16 is mounted a cable. pulley or drum 18 while within the body A of the boat along the sides thereof and suitably supported are guide rollers or pulleys 19, over which is trained an endless cable 20, the same being also trained over the pulley or drum 18 on the shaft 16 at the bow or fore end of the body A of the boat, the cable 20 being also coiled about an operating drum or pulley 21 which is located at a convenient point near the stern end of the boat A within the body thereof,

and this pulley 21 is carried by a driven stud shaft 22 having a worm gear 23 with which meshes a worm screw 24: operated by a hand wheel 25 so that the bow rudder can be turned as the occasion may require for the guiding of the boat in any desired course. Trained about the pulley or drum 18 on the stem 16 at the stern end of the boat A is an endless cable 26 which is also coiled about an operating pulley or drum 27 on a stud shaft 28 which carries a worm gear 29 meshing with a worm screw 30 having a hand Wheel 31 which permits the manual manipulation of the stern rudder and brake, as will be clearly obvious.

When the blades 11 both at the bow and stern of the body A of the boat are disposed at right angles to the straight course of travel the same will serve as a brake to retard the momentum of the boat and on angular disposition of the said blades 11 the boat will be maneuvered for the guiding thereof in any desired course.

It will be apparent that by adjustment of the blades 11 which constitute the combined rudders and brakes the boat can be moved obliquely from a straight course either to the right or the left and also either a right or left sharp turn can be effected.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the herein described boats rudder will be readily apparent and, therefore, a more extended eX- planation has been omitted.

Having thus described my invention, I claim:

1. In a boat having a framed opening in one end of its body, a blade forming a rudder having opposed clutch and pivot sockets, a pivot stud arranged within the framed opening and received in the pivot socket in the blade, and a driving member rotatably mounted in the body and adapted for sliding movement and having a clutch head for engagement in the clutch socket in the blade.

2. In a boat having a framed opening in one end of its body, a blade forming a rudder having opposed clutch and pivot sockets, a pivot stud arranged within the framed opening and received in the pivot socket in the blade, a driving member rotatably mounted in the body and adapted for sliding movement and having aelutch head for engagement in the clutch socket in the blade, and means for operating said driving member and supported within the boat.

3. The combination with a boat body having framed openings in the bow and stern thereof, of rudders, each comprising a blade having opposed clutch and pivot sockets, means arranged in the openings for pivotal engagement in the pivot sockets in the blade, stems rotatably and slidably journaled in the body and having clutch heads for detachable engagement in the clutch socket .in the blade, and means arranged within the body for rotating the stem.

4. The combination with a boat body having framed openings in the bow and stern thereof, of rudders, each comprising a blade having opposed clutch and pivot sockets, means arranged in the openings for pivotal engagement in the pivot sockets in the blade, stems rotatably and slidably journaled in the body and havingclutch heads for detachable engagement in the clutch socket in the blade, and means arranged within the body for rotating the stem, each blade being of substantially truncated elliptical shape.

5. The combination with a boat body having framed openings in the bow and stern thereof, of rudders, each comprising a blade 'having opposed clutch and pivot sockets,

means arranged in the openings for pivotal engagement in the pivot sockets in the blade, stems rotatably and slidably journaled in the body and having clutch heads for detachable engagement in the clutch socket in the blade, means arranged within the body for rotating the stem, each blade being of substantially truncated elliptical shape, and reinforcements on the blade.

In testimony whereof I atfix my signature.
