The present invention relates to a mechanism for propelling boats and more particularly to means for actuating an outboard screw propeller. It is an object of the invcntion to provide a fluid actuated'and manually operated motor for driving the propeller, the-mechanism being operated by a motion simulating that employed to row with the ordinary type of ours. It is also an object of the invention to provide a steering device attached to the driving mechanism and removable therewith.

partly in section, of means for attaching the motor to the boat;
Fig. 4 shows one form of connecting rod for the lovers; 4
Figs. 4 and 4 show a modification of the steering mechanism.
Referring to the drawings it will be seen that, in a cylindrical tube 1, is mounted a rotatable. vertical shaft2 on which is secured a plurality of spacing rings 3. A worm sleeve 4 fits on the shaft 2 being spaced therefrom by the rings 3. The lower end of the sleeve 4 is provided with an internalclutch face, preferably octagonal in shape and designed to engage a similarly shaped chamfered portion on the lower end of shaft 2. A coil spring 7 surrounds the lower end of the worm and cooperates with shoulders on the shaft 2 and worm 4 normally to hold the octagonal portions of these members out of engagement, under which conditions the Worm and shaft are rotatable with respect to each other. A piston 8 is slidable longitudinally of the tube 1 at the lower end of which is an air outlet 10 communicating with the atmosphere through the tube 9. To prevent rotation of the piston keysor other suitable guides 11 on the piston. cooperate with lon itudlnal grooves provided in the. tube. n
this manner, upon reciprocation of the pis-.
ton, the construction of which will be explained hereinafter, the worm is rotated and imparts its rotation to;thepropeller.
A curved tubular member 12 is secured to the upper end of tube 1 by means of a packed coupling 13 and a supporting member 14 clamped by means of a thumb screw 15 to the stern of the boat supports the tubes 1 and 12 in properposition, an ad justable collar 16 being provided for varying the height of the tube with res ect to the water line. To an arm 17, whic may be formed integral with the tube 12, is pivoted as at 25, a tillerarm 18. A flexible connection 19 rovides communication between the llltGIlOYOf tube 1 and the pump cylinder 20, suitable air-tight couplings 21 clamping the connectionto the tube and pump. A piston 20 is adapted to fit tight;
ly in thecylinder and reciprocate therein,
being operated by a lever 22 pivoted to the base 29 of the pump. This base is clamped to the bottom of the boat by a plurality of clamps 23. A seat 24 is so positioned with respect to the lever 22 thatthe pump may be operated much in thesame are manipulated.
The operation of this form of the invention will be apparent from Fig. 1 in which it will be seen'that, there bein an air-tight it conduit between pistons8 an 20', there. ciprocation of piston 20' will produce a corresponding displacement of piston 8. The latter tically ut cannot rotate. Due to itsooops oration with the worm 4 the. latter is rotated manner as ours iston is constrained to move 1 when the piston 8 is reciprocated. The
spring 16 is desi I worm 4 and hold it out of en agementwith ed normally to support chamfered end of shaft 2;" at when the downward pressure of fluid acting on the.
In Fig. 1 is shown the manner in which the steering apparatus is operated. The tiller arm is provided with an aperture 28 to permit pivotal connection with the arm 17 (Fig. l) and has a se mental portion 27 provided with teeth designed to mesh with teeth 26 on the tube 1. The lower end of tube 1 is rudder-sha1: ed so that manipulation of the tiller 18 in the direction ca will effect a change in course of the boat.
A modified form of the invention is illustrated in Figs. 2 and 2 in which the tube 30 is provided with an interiorly thrcaded surface. The shaft 31 is square in cross section and, by means of bevel gearing, is adapted to rotate the propeller. The piston 32 is made in two parts, the lower part 33 being free to rotate with respect to shaft 31 and having threads or projections on its outer periphery designed to cooperate with the threaded interior surface of the shaft 31 to effect rotation of the piston. The upper portion 34 of the piston is provided with a square aperture so that it is constrained to rotate with shaft 31 but is free to move axially thereof. A spring 35 normally separates parts 33 and 34, but, as in the form of the invention shown in Fig. 1, pressure of the fluid from above overcomes the spring pressure and forces the parts into cooperative relation, serrated edges 34, being provided to insure engagement of the parts. The part 34 has an elongated portion 47 adapted to extend through the part 34, a ring 36 being clamped to the end of the portion 47 to limit the relative axial movement between parts 33 and 34. Part 34 also has a tubular portion 39 adapted to hold spring 35 in positionbetween the parts.
The pump in this form of the invention comprises an oscillating vane 42 pivoted within a casing 41, the latter having a cover plate 43 to permit access to the interior of the pump. A pinion 44 is secured to the vane 42 and cooperates with a toothed seg ment 45 forming part of the lever 22. The pump is connected to the tube 30 by means of a flexible hose connection between the port 46 of the pump and the tubular member 57 at the upper end of tube .30. This member 57 is rotatably connected to tube 30, a packed union 54 and sleeve 50 insuring a fluid-tight joint, the packing 49, however,
permitting relative rotation between these parts. In this form of the invention the handle 18 of the tiller is rotated, the bevel gear 51 on the shaft 52 being in mesh with a second bevel gear 53 secured to tube 30. The tiller shaft is designed to pass through the tube 57 and in order that the passage nay not be restricted the tube 57 is somewhat enlarged at the point where the tiller shaft passes therethrough as shown at 58 in Fig. 2".
The tiller and tube 36 are supported by a frame 60 and adjustable arm 61 clamped to the boat by a thumb-screw 62. The arm 61 is pivoted to frame 60 but a series of holes in the frame permits the elevation of lowering of the tube 30 and the propeller. A collar 63 on arm 61 is clamped on the tube 30.
It is obvious that more than one lever may be employed to operate the fluid motor, the modification illustrated in Fig. 4 employing three levers 22 connected together and adapted to be operated in unison by three persons seated on the seats 24 adj accnt each lover. The levers are pivoted to a block 90 held to the bottom 83 of the boat by thumbscrews 74 and are connected by rods 75, which, if desired, may be adjusted as to length as shown in Fig. 4. The motor 81 is mounted on a base 73 held to the boat bottom by screws 69 and having hooks 70 adapted to be engaged by one end of the frame of the motor. Thumb-screws 7 2 clamp the other end of frame to the boat, the bottom of the frame being serrated at 71 to prevent slipping. If desired, the motor may be provided with a handle 82 to facilitate its transportation.
The steering in this type of motor may be effected by foot levers 7 9, the tiller arm having a ring 7 6 to which cords are connected. The cords 80 are also connected to the foot levers and pass over pulleys 78 held to the sides of the clips 77.
From the above description it will be seen that I have provided a portable outboard motor which depends solely on manual power, is positive in operation, its compactness and weight permitting it to be installed with minimum diilliculty and in a limited space. While I have described several prcferred embodiments of the invention, it is obvious that such changes as fall within the scope of the invention are permissible with out departing from the spirit of the invention.
I claim:
1. A propeller apparatus of the class described comprising a boat, a propeller, a tubular member for supporting said propeller, said member being secured to said boat, a piston in said member, means for recipro eating said piston, a shaft within said member adapted to be rotated upon reciprocation of said piston, and means to operatively connect'said shaft to said propeller when the piston is moved in one direction and disconnect the propeller from the shaft when said piston is moved in the opposite direction.
