FRANKLIN E. STRIBLING, OF MATAGORDA, TEXAS.
DROP-PROPELLER FOR BOATS.
To all whom it may concern:
Be it known that I, FRANKLIN E. STRIB- LING, a citizen of the United States, residing at Matagorda, in the county of Matagorda, State of Texas, have invented certain new and useful Improvements in Drop-Propellers for 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.
The invention relates to a drop propeller for boats and more particularly to the class of motor boats whether large or small class whereby the same can readily move in shallow water upon the raising of the propeller and also permit said boat or craft to cross reefs in a body of water.
Another object of the invention is the provision of a drop propeller for a motor or other self propelled boat whereby the motive power can be utilized to the best advantage when the propeller mechanism has been lowered in the deep water below the said boat.
A still further object of the invention is the provision of a drop propeller for a motor boat whereby the said propeller can be lowered into deep water below the motor boat and the said propeller being mounted in a pivotal board whereby when said board is lowered the same will act as a balance or keel board for the boat so as to steady the boat in its movement.
Vith these and other objects in view the invention consists in the construction, combination and arrangement of parts hereinafter more fully described in detail and as illustrated in the accompanying drawings which disclose the preferred form of embodiment of the invention. However it is to be understood that changes, variations and modifications may be made such as come properly within the scope of the claims hereunto appended without departing from the spirit of the invention.
In the drawings :-Figure 1 is a side view of a boat partly broken away and showing the invention applied thereto and in a dropped position. Fig. 2 is a longitudinal sectional View of the boat with the drop propeller in an elevated position. Fig. 3 is a transverse sectional view of the boat showing the pivotal connection in detail of the board for the propeller shaft and the knuckle joint of the latter.

Serial No. 441,838.
responding parts throughout the several views in the drawings.
In the drawings the numeral 7 designates the hull of a boat which may be of the usual well known construction, and having in its stern a central open space 8 formed by longitudinally disposed spaced parallel boards forming side walls 9 and a transverse closing inner wall 10 which latter has an opening 11 receiving a bearing collar 12 through which passes the main driving shaft 13 of a motor or engine 1 L mounted within the hull of the boat.
At the end of the main driving shaft 13 is a universal coupling joint 15 which connects it with a propeller shaft 16 so that the latter can receive rotary motion at whatever angle the same is positioned. Said propeller shaft 16 is mounted centrally in a lowering board 17 having at its inner end a casting forming a central bearing sleeve 18 for the said propeller shaft and outwardly curved diverging arms 19 secured at dia metricallyopposite points to a pivot rin 20 provided with side journals or pivots 21 mounted in the side walls 9 to permit the raising and lowering of the said board 17 in the space formed by the said side walls in the hull of the boat.
On the outer end of the propeller shaft 16 is fixedly mounted propeller blades 22 which rotate in an opening 23 formed in the lowering board 17 at the end thereof projecting beyond the side walls forming the open space therebetween. To permit rocking movement of the ring 20 on its side journals or pivots 21 the side walls 9 are provided with circular concaved recesses 2 1 circumscribing the points of pivot connection of the said pivot ring with the side walls. The board 17 carrying the propeller shaft 16 is raised and lowered by a cable or chain 25 whereby the said board can be manipulated at the will of the operator.
Surrounding the opening 11 in the inner wall 10 and also the main driving shaft 13 is a stuffing boX 26 to exclude water from entering the hull of the boat at this point. To connect the lowering board 17 to the arms 19 of the casting there are provided securing plates or straps 27 which latter are secured to the said arms and board by fasteners 28 whereby the board is rigidly and securely held to the casting.
hen the boat is traveling in deep water the propeller shaft 16 is dropped below the hull of the said boat by lowering the board 17 from the open space 8 between the side alls 9 of the hull of the boat and which board 1'7 when in this position will act asa keel or guide for balancing and steadying the boatin its course ofttravel. Now should the boat come into shallow water the lowering board 17 is raised into thespace 8 between the side walls to permit the boat to travel in :the shallow Water Without a damage tical side Walls rising from the bottom of said boat a ring having-outwardly project- 1ng studs in actual ahnernent with each other and engaging the side Walls to form .a I iivot for said ring,,a board, a casting secured to said board and to the ring, a propeller shaft anounted in said casting disposed centrally longitudinally of the board,
a propeller on the outer end of the shaft,
thereof, and a knuckle joint connection between said propeller shaft and the driving shaft of thetmotor.
in testimony whereof, I affix my signa ture, in presence of two Witnesses.
