ALBERT T. OTTO, OF NEW YORK, N. Y.
MARINE MOTOR.
SPECIFICATION forming part of Letters Patent No. 663,185, dated December 4, 1900. Application filed May 6,1899- senn No. 715,796. (No model.)
To all whom it may concern:
Be it known that I, ALBERT T. OTTO, a citizen of the United States of America, and a resident of New York city, county of New York, State of New York, have invented certain new and useful Improvements in Marine Motors, of which the following is a specification.
My invention relates to marine propulsion; and it consists in an improved form of smallmotor and screwpropulsion apparatus attachable to and removable from the stern of a boat, and more specifically consists of certain improvements on and simplification of the mechanism disclosed in my application, Serial No. 701,282, allowed January 12, 1899.
The preferred form of apparatus embodying my invention is illustrated in the accompanying three sheets of drawings, in which Figure 1 is a side elevation of the completed apparatus with certain parts broken away. Fig. 2 is a vertical longitudinal section of the same with the motor removed. Fig. 3 is a detail section on line 8 s of Fig. 2. Fig. 4 is a detail horizontal section on line 3 s of Fig. 3. Fig. 5 is a rear elevation of the apparatus shown in Fig. 1'.
Throughout the drawings like referencefigures refer to like parts.
Any convenient form of small motor may be used; but I have illustrated a small gasolene-motorhaving ahorizontal cylinder 1, with piston and connecting-rod (not shown) directly connected to cranks concealed in a crank-chamber 2, the whole being supported on projections 5 of the main frame 6, which is attachable to and removable from the sternboard 7 of the boat by means of the clampingscrew 8 or equivalent apparatus. The crankshaft 4 of the motor is the driving-shaft of the propulsion apparatus, and the motor is set in operation by a few turns of the handle 3.
The vertical oscillating sleeve 9 is journaled at its upper end in a bearing on the crank- .chamber 2 and at its lower end in a projection 10 from the main frame 6. At the lower end of the oscillating sleeve 9 is the main hearing 11 for the hollow propeller-shaft, said bearing being supported from said sleevevby means of an elbow-casting 12 and also supported in part by the strap 13, fastened to the lower end of the rudder 14, which is also rigid with the oscillating sleeve 9. On the outer end of the rudder 14 is carried the outboardbearing 15 for the hollow propeller-shaft 16. The vertical sleeve 9, rudder 1 1, and propellershaft 16 may all be oscillated by means of the tiller 17, attached to the upper portion of the sleeve 9.
Twopropeller-blades 18 18 are mounted in the outer end of the hollow propeller-shaft 16 and are adjustable thereon by means of the pinions 19 19 on the inner end of the propeller-blades which respectively mesh with the short racks 2O 20, carried by the longitudinally-sliding shaft 21, said shaft and the above-described gearing being all concealed within the hollow propeller-shaft.
On the forward end of the longitudinallysliding shaft 21 is the grooved collar 22, into which the forked lever 23 takes. Said forked lever 23 is fulcrumed at 24 on the oscillating sleeve 9, and its upper end is connected by the link 25 to the handle 26, which slides longitudinally on the tiller 17. The drivingshaft 4, journaled at its upper end in the crank-chamber 2 of the motor and at its lower end in the oscillating sleeve 9, has the bevelgear 28, which meshes with the bevel-gear 27 on the forward end of the hollow propellershaft 16. l The mode of operation of my invention is as follows: The motor being set in operation by a few turns of the handle 3, the drivingshaft 4 transmits rotary motion to the hollow propellershaft 16. When the propellerblades are set in the position shown in Fig. 2, the propeller-shaft being rotated from left to right, looking toward the stern of the boat, the boat will be driven forward. The operator by swinging the tiller 17 will swing the whole oscillating frame, composed of the sleeve 9, rudder 14;, propeller-shaft bearings, and propeller-shaft carried thereby, so as to drive the boat forward or to port or starboard in the same manner as the boat is ordinarily steered by the rudder alone. 7
The pitch of the screw-propeller blades may be adjusted so as to drive the boat faster or slower by moving the sliding handle 26 iongitudinally along the tiller. When the sliding handle is in its foremost position, as shown in Fig. 2, under the previous assumption that the motor runs from left to right in the direcpeller-blades will be reversed and the motor still running in the same direction continuously the boat will back at full speed. Of
course the motor could be made to run in the opposite direction, and then the above-described arrangement would be reversed; but I prefer the arrangement as described, because then the longitudinally-sliding shaft 21 is in its rearmost position while the boat is going forward, and the pressure of the water on the front face of the collar 22 and the end of the sliding shaft will tend to keep it in that posit'ion. On the other hand, when backing the sliding shaft and collar will be in their foremost position,'and whatever resistance is ofiered by the water to such backward motion will tend to hold the longitudinally-sliding shaft again in its proper position for that particular motion.
It is evident, of course, that the whole apparatus could be lifted out of the water for storage or repair by releasing the clamping screw 8.
The ad vantages of my invention reside in its simplicity and lightness, resulting from the reduction of the number of parts, also in the strength resulting from having all the main parts rigidly connected together or j ournaled in the rigid oscillating frame formed thereby. Moreover, the gearing and adjusting mechanism for the propeller-blades being all concealed within the hollow propellershaft, there are no revolving projections to churn up 'the water and present useless resistance to the driving'apparatus. In fact, the whole driving and adjusting mechanism is concealed within the right-angled line of pipe formed by the oscillating sleeve 9, the propeller shaft and bearing 11, and the hollow propeller-shaft 16. The entire control of the driving apparatus both in steering and backing is also produced by the motions of the single handle 26. is, as hereinbefore described, that the action of the water through which the boat is moving normally tends to hold the reversing-gear in the proper position to efiect the motion which produces that particular action of the A further advantage.
thepropeller-shaft might be changed, other means of supporting thepropeller-shaft journalbearings from the oscillating sleeve might he used, and certain of the improved features of myinvention might be employed without ,othersherein described. All such changes, however, I consider matters of form and not of substance, and the resulting apparatus will stillbe within the scope of my invention.
Having therefore described my invention, what I claim as new, and desire to protect by 2 Letters Patent, is'
l. The combination of the stationary frame,
the verticalsleeve journaled therein, the propeller-shaft, the journal-bearings therefor carried by the vertical sleeve, the drivingshaft journaled in said sleeve, gearing between the' driving-shaft and the propellershaft, and means for oscillating said vertical sleeve about its axis, together with the rudder mounted on said vertical sleeve and the outhoard be'aring for the propeller-shaft carried by said rudder.
2. The combination of the hollow propeller-shaft, adjustable propeller-blades, a longitudinally sliding shaft within the hollow shaft, and gearing concealed within said hollow shaft connecting the propeller-blades with the l'ongitud-inal'ly sliding shaft,together with the grooved collar onthe forward end of the longitudinally-sliding shaft, which projects beyond the hollow propeller-shaft, means for supporting the propeller-shaft on a hinge having a vertical axis, and the forked lever engaging with said grooved collar.
Th'ecombination of the hollowpropellershaft, adjustable propeller-blades, a longitudinally-sliding shaft within the hollow shaft, and gearing concealed within said hollow shaft'connecting the propeller-blades with the longitudinally -sliding' shaft, together with the grooved collar on the forward end of the longitudinally-sliding shaft which projects beyond the hollow propeller-shaft, the oscillating vertical sleeve which carries the j ournal-bearings for the propeller-shaft, and the forked lever fulcru med on said vertical sleeve and engaging with above-mentioned grooved collar.
4. The combination of theoscillating frame journal'ed at the stern of the boat,'the propeller-shaft journaled in said frame, adjustable propeller-blades, the tiller whichswings the oscillating frame, thelongitu dinally-slid- 1 ing handle for said tiller, and mechanism carried by the tiller and oscillating frame connecting said sliding handle with the adjustable propeller-blades, comprising a shaft slidresistance of the water through which the boat is passing, normally tends to hold the propeller-blades in that position of adjustr5 ment which will move the boat in a manner to create said direction of water-pressure.
