ROBERT RUTHERFORD, OF MONTAVILLE, OREGON.
BOAT-PROPELLING MECHANISM.
Specification of Letters Patent.
Patented Jan. 15, 1907.
Appl cation filed January 16, 1906. Serial No. 296.276
To ctZZ whom it may concern:
Be it known that I, ROBERT RUTHERFORD, a citizen of the United States, and aresident of Montaville, in the county of Multnomah and State of Oregon, have invented a new and Improved Boat-Propelling Mechanism, of which the following is a full, clear, and eX- act description.
The invention relates to a peculiar device for manually propelling boats and smaller marine vessels by means of a screw-propeller.
In carrying out my invention I mount the propeller on the shaft as usual, and I connect the same with a double crank-shaft within the boat. In this crank-shaft is fastened a fly wheel or wheels, and above the same is erected a scaffold on which is arranged a walking-beam. The walking-beam has a peculiar handle, by means of which it may be rocked by an operator seated, preferably, on the stern-sheets of the boat, and said walking-beamhas peculiarly-arranged connectingrods joining its ends with the crank-shaft. The walking-beam extends fore and aft to facilitate its manual operation, and the connecting-rods are allowed a lateral swinging movement on the walking-beam to accommodate the throw of the cranks and are further allowed a fore-and-aft swinging movement to accommodate the throw or are through which the ends of the walking-beam move.
Reference is to be had to the accompanying drawings, which illustrate as an example the preferred embodiment of my invention.
In the drawings, Figure 1 is a longitudinal section of a boat equipped with my invention. Fig. 2 is an enlarged side elevation of the motor. Fig. 3 is a front view of the same, and Fig. 4 is a detail section showing the joint between the walking-beam and the connecting-rod.
As shown in Fig. 1, the propeller 10 is mounted aft of the stern-post of the boat on its shaft 11 in the usual manner. Said shaft is coupled to a crank-shaft 12, (best shown in Fig. 2,) which is mounted in bearings 14, carried in a suitable bed 15. Erected on said bed is a scaffold or frame 16, having a journal 17 therein which carries the walkingbeam 19. Said walking-beam is arranged within the scaffold and extends fore and aft of the boat. Secured to the walking-beam, preferably at the middle thereof, is a tubular arm 20, in which a pin 21 is adjustably held by means of a set-screw or other device 22. Sa1d pin 21 carries at its upper end a transverse handle 23, and through this handle and its connections 21 and 22 the walking-beam may be rocked upon the horizontal axis of the journal 17.
The ends of the walking-beam are formed with sockets 24 therein, (best shown in Fig. 4,) and in said sockets arev arranged the spherical upper ends 25 of the connecting-rods. Said spherical ends 25 are held in the sockets 24 and are allowed a universal movement therein through a limited arc by means of pins 27 which pass through the walls of the socket members. The connecting-rods are composed of upper members 26, which telescope into tubular sections 27.
28 indicates set-screws for holding the parts'27 and 26 in the desired adjustment.
The sections 27 have joints 29 connecting them with the lower sections 30 of the connecting-rods, The ball-and- socket connections 24 and 25 permit the connecting-rods to swing thwartships to allow for the move ment of the crank 12, while the joints 29 permit the upper parts 26 and 27 of the connecting-rods to swing fore and aft to accommo date the arcs in which the ends of the walking-beam move.
It will thus be seen that an operator seated on the stern-sheets of the boat or, if desired, two operators, one seated on the stern-sheets and one on the after-thwart, may, through the means of the handle 23 and its connections, rock the walking-beam 19 imparting a rotary movement to the crank-shaft 12 and to the propeller-shaft 11, which is coupled thereto. In this manner the propeller may be rapidly driven and the boat propelled.
Having thus described the preferred form of my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a boat-propelling mechanism, the combination of a crank-shaft, a me; her extending longitudinally of the crank-shaft and crank-shaft'andhaving a ball-and-socket connection With said member, the connecting-rod also having a joint therein permitting a part of the rod to move in a plane extending longitudinally of the crank-shaft.
3. In a boat-propelling mechanism, the combination of a double crank-shaft, a Walking-beam extending longitudinally of the crank-shaft, a handle secured to the Walkingbeam, and connecting-rods joining the ends of said beam respectively 'With the cranks of the shaft.
- 4. In a boat-propelling mechanism, the combination of a double crankshaft, a Walking-beam extending longitudinally of the crank-shaft and rocking around an axis transverse thereto, and connecting-rods joining the ends of the Walking-beam respectively a With the cranks, said connecting-rods having vibratory movement on the Walking-beam to accommodate the throw of the cranks, and the portions of the rods in connection With the Walking-beam having movement longitudinally ofthe crank-shaft to accommodate the swing of the ends thereof.
5. In a boat-propelling mechanism, the combination of a double crank-shaft, a Walk ing-beam arranged to rock around an axis transverse thereto, said Walking-beam having socket members at its ends, and connecting-rods having spherical ends Working in the socket members, the connecting-rods being joined respectively to the cranks and having joints therein permitting the parts of the rods in connection With the Walking-beam to move longitudinally of the shaft to accommodate the movement of the Walking-beam.
6. In a boat-propelling mechanism, the combination of a double crank-shaft, a scaffoldrising therefrom, aWalking-beam extending longitudinally of the crank-shaft and mounted on the scaffold, connecting-rods joining the ends of the Walking-beam to the crank-shaft, a tubular arm projecting from the Walking-beam, and a handle member having a part adjustably fitted in the said tubular arm.
In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
ROBERT RUTHERFORD.
