J B. KIBLER.
PROPELLER FOR SMALL BOATS.
No. 300,982. Patented June 24, 1884.
UNITED STATES PATENT OFFICE.
JOHN B. KIBLEB, OE MINNEAPOLIS, MINNESOTA.
PROPELALER, FOR SMALL BOATS.
SPECIFICATION forming part of Letters Patent No. 300,982, dated June 24, 1884.
Application filed March 27, 1884. (No model.)
T0 aZZ whom it may concern v Be it known that I, JOHN B. KIBLER, a citizen of the United States, residing in Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Propellers for Small Boats, of which the following is a description.
Figure 1 is a perspective view of my improved boat, and Figs. 2 and 3 are detail views.
cured to the outside or inside of the boat by screws or bolts, and adapted to receive a removable post, 0, which may be adjusted vertically, as desired, by means of a set-screw, d. The upper end of the post 0 is provided with an arm, 0, secured to it. The outer end of the arm 6 has a loop, 6, for the passage and play of the paddle-bar 9, provided at its lower end with the'paddle 9, having an'inclined position relative to the surface of the water. The upper end of the paddle-bar g is provided with a cross-pin, above the loop e, to act as a stop-pin for the paddle-bar {1. To one paddle.
edge of the paddle-bar g is secured a plate, h, to prevent wear of the parts in operating the i represents a plate provided at its ends with shoulders i, having flanges 1'', provided with holes, whereby the plate 13 is bolted to the edge of the paddle-bar 9, over the plate h, thus forming a slot, i in the connection with the paddle-bar without weakening the latter by forming a slot in it.
' A represents a block provided with the flanges Z l, embracing the opposite sides of the post 0, and secured thereto by a bolt and nut. The block A is also provided with two bearing-arms, m m, in which the crank-shaft n is journaled. The outer end of the crank-shaft a is provided with a lug or projection, a, permanently secured thereto.
to the edge of the paddle-bar y, when the plate The crank-shaft n is placed against the bearing-plate h, secured 13 is removed, so that the lug a, permanently secured to the crank-shaft, is in place, and the plate 11 then secured in place over the bearingplate h. By this construction, in lieu of a removable nut usually employed in such constructions, there is no liability of the crankshaft becoming detached from the slot by the unscrewing of a nut, as in the ordinary construction, because the lug or projection n is permanently secured to the crank-shaft. By this construction, by turning the crank-shaft, the boat may be propelled in any desired direction.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination,with abottomless socket secured to the side of a boat, of an upright post adjustably secured in said socket, and provided with a guide for the paddle-bar at its upper end, and a crank-shaft for operating the paddle-bar journaled in the upright post,
substantially as shown and described.
2. The combination, with bottomless socket 12, secured to the side of a boat, and a removable post, 0, adapted to be vertically adjusted in said socket, and provided with. an arm, 6, having a loop, 6, at its outer end, of the slotted paddle-bar 9, block A, and crank-shaft a, substantially as shownand described.
3. The combination, with the paddle-bar 9,
provided with a plate, h, of the removable plate a, provided with shoulders 13, having flanges d substantially as shown and described.
4.. The combination, with the paddle-bar provided with the plate h, of the removable plate 1', provided with shoulders 2', having flanges 2', and crank-shaft it, having projection a, substantially as shown and described.
5. The combination, with the adjustable and removable post 0, of the block A, provided with flanges Z Z, embracing the post, bearings m m, and crank-shaft n, substantially as shown and described.
The above specification of my invention signed by me in the presence of two subscribing witnesses.
