HAND-PROPELLED MOTOR-BOAT.
Specification of Letters Patent.
Patented Jan. 18, 1910.
Application filed. May 28, 1909. Serial No. 498,794.
b all whom it may concern:
Be it known that I, MAGELLAN ALBER- MAN, a citizen of the United States, residing at Osprey, in the county of Manatee and State of Florida, have invented certain new and useful Improvements in Hand-Propelled Motor-Boats, of which the following is a specification.
This invention relates to certain new and useful improvements in manually-operated motor boats.
The object of my invention is to provide a simply constructed, effective and readily operated motor, arranged for use in light pleasure boats, enabling the operator to obtain a greater speed than is possible with the use of cars at the expenditure of the same amount of manual power.
lVith these and other objects in view the invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the claims, it being understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.
In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a fragmentary sectional view taken through the stern portion of a boat provided with my propelling mechanism, Fig. 2 is a top plan view thereof, Fig. 8 is a detail front view of the rock lever, Fig. 1 is a front view of the internal gear and connecting shaft.
In the accompanying drawings, 5 represents the stern end of a pleasure boat pro- ,vided with the usual stern seat 6 and rudder 7. The seat 6 is supported by means of a post 8. Secured to this post 8 is a bearing 9, this bearing supporting a stub shaft 10 which stub shaft in turn carries the beveled gear 11 provided with a wrist pin 12 from which extends the crank rod 13 as clearly indicated in Fig. 1.
Held to a bearing within the post 8 is the driving shaft 14 which at its rear end is held within the bearing 15 secured to the stern of the boat. This shaft 14 is provided with an internal gear 15 which is made heavy enough to serve the purposes of a fly wheel. The outer peripheral edge of this internal gear is rounded as is shown at 16 so as to present a convenient edge to be grasped by the hand of the operator. EX- ten-ding from and forming a portion of this internal gear 15 is the exteriorly connected bevel gear 17 which also serves as the hub of the fly wheel forming gear 15. This gear 1'7 is in mesh with the bevel gear 11 upon the shaft 10 which is disclosed in Fig. 1.
Held within the bearings 19 and 20 and secured to the stern of the boat, as disclosed in Fig. 1 is the propeller shaft 21 at one end carrying the propeller 22 and at the other end is the pinion 23 meshing with the internal gear 15 as disclosed.
At a suitable point. in front of the seat 6 I provide the supporting bracket 25 which near its upper end has the supporting pin 26 carrying the rock lever 27 as disclosed in Fig. 3. This lever at its upper end has the operating handle 28 while the lower end is forked to provide the slot 29 within which the front end of the crank rod 13 is held, the rod being secured by means of the pin 30. The lower forked ends of this operating rock lever are slotted as disclosed at 31 to slidably receive the threaded end 32 of the foot rest 33 as clearly indicated in Fig. 8. By means of suitable nuts 84:, these foot rests are secured to the rock lever. The seat 6 as disclosed in Fig. 2 is recessed or slotted as shown at a; to provide access openings so that the operator can reach down and grasp the outer peripheral edge of the fly wheel 15 in starting the machine, stopping it or reversing the propeller.
The operator in driving the motor grasps the handle 28 while at the same time placing his feet upon the foot rest 33. Then in imparting a rocking motion to the lever 27, the propeller 22 will be revolved by means of the intermediate gearing as disclosed. The rock lever 27 is provided with a plurality of openings 38 within which the pin is adjustably held so as to regulate the stroke of the lever 27. By this arrangement a high speed may be imparted to the propeller 22.
The rounded smooth edge 16 of the fly wheel provides a ready hand-hold for the operator who can thereby not only check the speed of the wheel in stopping the propeller but can also instantly reverse the propeller.
And having thus described my said invention, what I claim as new and desire to se cure by United States Letters Patent is:
1. The combination with a boat having a stern seat provided with two access openings, of a drive shaft beneath said seat, an internal gear serving as a fly wheel and having an exterior connected bevel gear, a propeller shaft extending through the stern of the boat and provided with a pinion mesh ing with said internal gear, a bevel gear mounted adjacent to said first mentioned bevel gear having a wrist pin, a crank rod extending from said pin, a rock lever pivoted intern'iediate of its end, said crank rod being adjustably secured to said lever, an adjustably-secured foot rest secured to the lower end of said lever.
Q. The combination with a boat having a stern seat provided with two access openings, of a drive shaftpositioned below said seat, an internal gear serving as a fly wheel and having an eXteriorly connected bevel gear secured to said drive shaft, a propeller shaft mounted below said drive shaft, a pinion carried upon said propeller shaft, and meshing with said internal gear, a bevel gear mounted adjacent to said first mentioned bevel gear having a Wrist pin, a crank rod extending from said wrist pin, a rock lever having its end forked, a supporting pin secured to the forked end of said lever, a supporting bracket carrying said pin, said bracket being held between the forked ends of said lever, said crank rod being adjustably secured to said lever, and foot rests adjustably secured to the forked end of said operating lever.
In testimony whereof I atlix my signature, in presence of two witnesses.
MAGELLAN ALDERMAN.
