ITE@ STATES PATENT OFFICE.

JNO. BEATTIE, OF LIVERPOOL, ENGLAND.

MEANS FOR SUPPORTING- THE PROPELLER-SI-IAFT AND RECEIVING THE RUDDER OF STERN-PROPELLERS.

Specification of Letters Patent No.

To all whom t may concern:

Beit known that I, JOHN BEA'r'rIE, of Liverpool, in the county of Lancaster, England, engineer, a subject of the Queen of Great Britain, have invented or discovered certain new and useful Improvements in Constructing Vessels Propelled by Submerged Propellers; and I, the said JOHN BEATTLE, do hereby declare that the nature of my said invention and the manner in which the saine is to be performed is particularly described and ascertained in and by the following description thereof, reference being had to the drawings hereunto annexed and to the letters and figures marked thereon.

My improvements consist in a peculiar construction of the after part of a ship or vessel which enables ine to place the propeller beyond the rudder with perfect safety by passing the shaft of the propeller directly through the rudder and through an inner and outer stern post, the shaft being supported by and resting upon the said outer stern post.

In the accompanying drawing Figure 1 represents an elevation of the rudder and its appendages with the propelling shaft carried through the rudder.

A and B indicate the rudder formed in two parts which are connected together by being firmly aliiXed to the rudder post- C C.

Through the middle of the rudder post an elongated hole is formed shown in the transverse view of the central part of the 14,081, dated January 15, 1856.

rudder post in Fig. 2 which hole is to allow t-he propelling shaft D t0 pass freely through whatever may be the angular position of the rudder. rIhe stern post consists of a strong iron frame E E E affixed vertically and forming one piece with the keel H at the stern of the vessel, hence the stern post embraces and carries the rudder A B which is hung upon hinges or centers, and is worked by the ordinary apparatus attached to the top of the rudder post C.

The propelling shaft D D is put in motion in the ordinary manner by a steam engine within the vessel and has a bearing in the stern post beyond the rudder as shown at Fig. 3. To the outer end of the propelling shaft the boss F carrying the vanes or paddles Gr Gr is to be keyed.

I would state that it is not new to have the rudder divided, nor is it new to place t-he propeller beyond or astern of the rudder, and I make no claim thereto.

Having thus described the nature of my said invention and the manner of perform ing the same I would have it understood that what I claim is- The construction of an open wrought iron stern frame E E E forming part with the keel H of the vessel and receiving the rudder substantially as above described.

JOHN BEATTIE.
