JOHN W. MARTIN, OF SCOTTSBURG, INDIANA.
tflARiNE VESSEL.
Specification of Letters Patent.
Patented sept. 11, 1906.
Application tiled September 5,1905. Serial No. 276,989.
To all warmt t waa/J concern:
Be it known that I, JOHN W. "MARTIN, a citizen ef the United States, and a resident of Scottsburg, in the county of Scott and State of Indiana, have invented a new and lmproved Marine Vessel, of which the following is a full, clear, and exact description.
The invention relatesto aniarine vessel adapted particularly for use in shoal water, the boat or vessel being equipped with a propeller, the position of which-may be changed at will, so that the propeller may extend Vdownwardly below the keel of the vessel or in the lowered position and illustrating the coacting parts. Fig. 2 is a similar. view except that the propeller 'is raised. Fig. 3 is a stern view showing theI propeller lowered. Fig. 4 is a similar view showing the propeller raised. Figs. 5 and 6 are details of the steering-gear, and Fig. 7 is a horizontal section taken approximately along the line 7 7 of Fig. 1..
The sternor after portion of the boat or vessel is constructed with a cavity 10, which runs fore and aft from the transom to a transverse wall 11, formed at the forward extremity of said cavity.
12 indicates the crank-shaft of the engine or a shaft in connection therewith which transmits the motive force. This shaft is mount-ed in a suitable bearing in a supportingwall 14, located in the boat just forward of the wall 11, and the after end of the shaft 1.1 is connected by a universal joint 15 with a solid shaft 16, constituting the driving-shaft of the reversible propeller 17.
18 indicates a tubular shaft which incloses the solid shaft 16 and is in connection with` the propeller 17, so that upon sliding the shaft 18 the propeller may be reversed, all of which will be understood from the prior art. The tubular shaft 18 has a collar 19, with which a suitable shifting device 20 is join-ed and by means of which the propeller may be Loosely inclosing the tubureversed at will. lar shaft 18 is a hollow arm or sleeve 21, the inner end of which passes through a vertically-elongated opening 11'L in the wallll. Leakage through said opening 'ilil is prevented bymeansofa flexible boot 22, whichis clamped to the tubular shaft or arm 21 and fastened te the wall 11, as shown. The inner extremity of the tubular arm or shaft 21 has a yoke 23 fastened thereto. Acting between said yoke and the tubular shaft 18 is a packing and gland 24, which prevents leakage from the tubular arm 21 into the hull of the vessel. Said yoke 23 is pivoted within the` hull by means of trunnions 25, (shown best in Fig. 7,) so that the yoke,with the parts 16, 18, and 21, ma swing freely, the shaft 16 being constant y driven, however, through the universal connection 15 and shaft 12, before explained. Connected to the end portion of the tubular arm or shaft 21 is a 'bar26, which extends up' through the deck'of the vessel at the stern thereof and is provided with a handle 26a, by means of which the barmay be conveniently lifted. Below the deck of the vessel the bar is guided by a bracket 27, and below this bracket the bar is joined to the tubular arm 21 by a clip or other fastening 28, which may be of any desired form.
29 indicates guard-rods, which are fastened .by clips 30 to the tubular arm 2] and which rods extend rearward and are bent inward, as indicated at 29a, into engagement with the before-mentioned clip 28. One of the guardrods 29 is fastened to the lower extremity of the bar 26, the bar projecting below the shaft 21, and saidguard-rod has an extension 29", on which the lower end of the rudder-post 3'1 is stepped by a bearing 32. The rudder33 is fastened to the rudder-post in the usual manner.
The bearing 32 is of the ball-and-socket` type, which enables free relative movement of the parts 29 and 31. the post 31 is square or angular in form and slidably fits in a sleeve 34, which is shaped corresponding to the shape of the rudderpost. Said sleeve 34 has collars 35 thereon, and between these collars a ring 36 is engaged. This ring is held in position in the free to slide through the sleeve 34; but said' The sleeve and rudder-pest turn as a unit. sleeve 34 has oppositely-projecting arms 38,
IOO
Above the. rudder 33 to which the tiller-roples (indicated by broken lines 39 in Figs. 1 and 2) are attached. By means of these ropes, therefore, the rudderpost, and Consequently the rudder, may be At the same time the rudder turned at will. is 4free'to move vertically with the parts 21,
29, and 26 from the position-shown in Fig` 1 motor, which discharges into an exhaustchamber 41, and this is provided with a union 42, passing through the bottom of the boat.
above the before-described opening and in turn joined to a flexible pipe 43, the end. of
I purpose the which is connected by a clip 44 with the tubular arm 21', so thatthe said exible pipe is raised or lowered with the arm, as illustrated in the drawings.
4In the use or operation of the invention the propeller is effective whether in the position shown in Fig. 1 or that shown in Fig. 2. Since, however, it is sunken deeper in the water when adjusted as in Fig. 1, it is more effective during this adjustment, and consequently when there is sufficient water for the arts should be lowered, as in ig. .1. At t stime the shaft 12 drives the propeller through the transmitting parts beore described,y and the operation 1sl precisely the same as in the ordinary propeller-driven boat or vessel. When reaching shoal water,
it is only necessary to lift thel bar 26, which simultaneously raises the rudder and propeller to aA oint above the keel or lbottommost line oft e vessel. The operation then continues, though not so effective as before, and vwhen deep water is again reached the parts may be dropped, as will beunderstood from the foregoing description.
It is pointed out that with the above-described arrangement should an obstruction i SQV of any sort be encountered the same will be engaged by one or several of the guards 29, and the pro eller-shaft and all of its connected parts wil be raised clear of the obstruction, said .parts entering the pocket 10 in the stern of the boat, which is provided for this purpose. The pocket is so shaped that it will -pro erly receive the propeller-shaft and its Vattac ments. In this way the apparatus is made to automatically pass over any obstruction lying below the keel-line of the boat. The handle 26 is provided to permit manually raising'the shaft and other arts, and, if desired, by means of this handle the shaft-may be secured in raised position, for example,
while the boat is lying to anchor. Said han.
able propeller-shaft, for the purpose specified, an eXhaust-chamber,and a 'flexible pipe communicating with the exhaust-chamber and having one end connected with the propeller-shaft to move therewith.
2. The combination with a marine vessel having an o ening in the rear thereof, of a swinging yo e mounted within-the vessel, a tubular arm or shaft attached to theyoke and'extendin'g out through the opening in the rear of the vessel, means in connection with said tubular arm or shaft for laterally moving it, a flexible boot connected to the tubular arm and secured to the hull of the vessel around said opening to prevent leakage through the opening, a propeller-shaft mounted in the tubular arm, Aa propeller in connection with the shaft, and a universal joint connei-ating the propeller-shaft with the driveshaft.
3. A marine' vessel having a propellershaft, a universal joint connecting s aid shaft with the driving-shaft, a tubular shaft encirclingv the propeller-shaft, a propeller in connection with the propeller-shaft, side andv bottom guard-rods, connected with the tubular shaft, a rudder-post having a rudder and connected. with the bottom guard-rod, andy means connected with the tubular shaft for.
vertically swinging the propeller-shaft.
4. The combinationV with a marine vessel having an o ening in thev rear thereof, of a swinging yo ie mounted within the vessel, a
tubular shaft attached to the yoke and eX- tending through the opening, a pro ellershaft mounted the tubular shaft, si e and bottom guard-rods connected with the tubular shaftand extending beyond the propeller,
a rudder mounted on thebottom guard-rod,
and means for swinging the tubular shaft in a vertical plane.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
