Specification of Letters Patent. PatggntgdpAp 11, 1922.
Application filed August 24 1921. serial in); 494,909.
T ouZZ whom it may concern Be it known that" I, ANTHONY BINK, a citizen of the United States, residing at Stockton, county of San Joaquin, State of California, have invented .certain new. and
useful Improvements in Boat Propellers;
and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application. 7
This invention relates to improvements in boat propulsion, the principal object being to devise a means for propelling a boat through the water by power which will eliminate churning of the water and the inevitable slip had with the usual screw propellers, which absorbs from twenty to thirty per cent of the power.
' I have also provided a propulsion means in which all the power is used beneficially, none being wasted in lifting the water or acting on it at a,disadvantageousangle as is the'case with the ordinary side or stern paddle wheels when the paddles leave or enter the water. V
I have also provided a device whereby the propulsive effort is applied to the water at as many points as may be desired in the length of a craft in much the same manneras a number of oars may be used on each side of a rowboat with good effect, no one oar interfering with, another or exerting any lesser propulsive effort on the boat on ac count of other oars being in front 'andbehind.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efiective for the purposes which it is designed. V
These objects I accomplish by means of such'structure andrelative arrangement of parts as will fullyappear by a perusal of the following specification and claim.
In the drawings :similar characters of reference indicate corresponding parts in the several views. '1
Fig. 1 is a side elevation of a boat equipped with my improved propellers Fig. 2 is an end view of the same.
Referring now more particularly to the characters of reference on thedrawings, the numeral 1 denotes a hull of any suitable and ordinary design and form journaled in which at suitable points in the length of the hull and'transversely thereof a certain distance abovethe water line are-sl1afts"2 one of which is connected to be driven by any suitable power plant as at 3. The outer ends of each shaft is provided with double op posed crank arms 4, the outer one of which I is formed with a stub shaft 5 in line with the main shaft 2 and journaled in hangers 6 connected to but spaced from the sides of the hull.
Extending between and beyond and pivotally connected to corresponding cranks on each side of the hullare bars 7 each of which is "provided with a plurality'of preferably evenly spaced and rigidly fixed vertically disposed discs or plates 8, at right angles tothe bars or in thetransverse plane'of the hull.
In order to make. for smoother action the cranks on one side areflset at an angle to those on the other. as is done with locomotives and similar'mechanisms. 4 Inoperation, since the center shafts and cranks is above the water line, the discs do not enter the water at the forward end of the hull until they are in a position to move straight down into the water without any angular pressure thereontending to absorb any power in wasteful effort.
Further movement of the shafts and cranks ,forces the discs 8 back through the water with theirentire area bearing squarely V thereaga'mst, or rather, the contact points of the discs or'blades with the water being line of the.
considered as the fulcrum of the crank arms,
the hull will move ahead while the discs re main practically stationary. When the discs are raised out of the water, they slide out practically inacvertical plane, their thicknesslof course offering but little resistance to such movement, and hence but very little power is absorbed or consumed in so doing.
As soon as one set of discs "on a side leaves the water, the other'set on the same side is about in position to engage the water in the manner-previously set forth to exert. a fur-7 ther propulsive effort, and therefore a continuous forward movement of the craftis obtained with almostno lost motion.
From the foregoing description it.will' be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.
While. this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.
Having thus described my invention, vvhat I claim as new and useful and desire to secure by Letters Patent is:
A propulsive means for boats comprising opposed crank arms pivotally mounted in the hull of the boat at spaced intervals in the length thereof and being outside the hull on both sides, and arranged to be rotated, bars pivotally mounted to and extending between the corresponding cranks on each side and there beyond, and vertical plates fixed on 15 the bars and disposed transversely of the hull, there being one of said plates at each extremity of each bar beyond the connection thereof with the cranks.
In testimony whereof I aflix my signature. 20
ANTHONY BINK.
