Specification of Letters Patent.
Patented Aug. 5, 1919.
Application flied January 16, 1919. Serial No. 271,407.
To all whom it may concern:
Be it known that I, STATES LEE Laser, a citizen of the United States, and resident of Charleston, S. (I, have invented certain new and useful Improvements in Hydroplane- Boats, of which the following is a specification.
My invention relates to boats and aims to provide a construction of boat to be propelled by power or made to move over the water at high speed with the least resistance or expenditure of power, as a hydroplane, aeroplane pontoon or boat otherwise driven. My invention is mainly intended to provide a construction of boat which is driven at high speed with minimum power; said results being obtained by a special construction of the bottom and sides of the boat so that the squatting or settling of the stern due to the displacin action of the propeller is entirely overcome y said construction for neutralizing said action and causing the hull to lift and glide freely over the water. For simplicity the bilge or chine lines are herein referred to as knuckle lines.
My invention is based on the fact that the volume of water displaced by the propeller is approximately equal to that displaced by the boats bow entrance through the water which bow displacement by my construction is efliciently utilized in replacing the displaced propeller volume thereby overcoming this heretofore vital hindrance to the speed of boats. My construction also utilizes said bow displacement or bow wake in such a manner that in rough water any quantity of air passing under the boat is effectively diverted from propeller by the longitudinal middle bottom section under the stern end of which the propeller functions. My steering mechanism comprises a rudder for turning in each direction, one placed to either side of the stern and with the upper edges of the blades tilted at an angle toward the center line of the boat so that by actuating the outward rudder from the direction of turning the rudder lifts and at the same time skids the stern of the boat around. The design covered by my invention has further features; of extreme strength for the weight of said construction and one of extreme simplicity which is easily built.
My invention includes the novel features of construction hereinafter described, the said invention being defined by the claims appended hereto.
The preferred embodiment of my invention is illustrated in the accompanying drawing, in which,
Figure 1 is a side elevation.
Fig. 2 is a plan view.
Figs. 3 to 7 are respective sections in the correspondingly numbered section lines of Fig. 1.
Fig. 8 is a rear elevation.
Referring by reference characters to this drawing A designates the hull of the boat and A is the bow and A is the stern. A. designates the keel and on each side of this keel I provide a eoncaved portion a, this concaved portion extending practically the full length of the bottom with cast and 31-19 the knuckle or chine lines.
In my preferred embodiment as shown in the drawings the bow is square and inclines downwardly and rearwardly to the point indicated at a and from this point the keel and chines take the same curve downwardly and rearwardly for a suitable distance, preferably to the point indicated by the section line H from which point it runs substantially straight or with a slight upward curve t the bottom of the stern section or board A Fig. 2 shows that the keel lines and the knuckle or chine lines are in parallel vertical planes. Also in Fig. 1 the knuckle and keel lines being in the same curve, are in the same straight lines transversely. The two concaved sections a are deepest at approximately the point indicated by the section line H and grow shallower as they approach the bow and stern, or in other words the center line of the concavities or channels in the stern run in a substantially straight line from the point a. to the bottom of the stern board or section indicated at a.
For the steering of my improved boat I provide a pair of rudders B on rudder stems b, one laced to either side of the stern substantia ly in line with the centers of the inverted V portions and with the said stems inclined upwardly and inwardly toward the center line of the boat.
Any suitable means may be provided for propelling the boat, such for example as a gas engine indicated conventionally at C operating the propeller D through the intervening propeller shaft E in the usual or desired manner. I
Having thus described my invention What I claim is:
l. A boat lmll having a V shaped bottom portion intermediate ofi two inverted lV- shaped portions, extending substantially the entire length of the hull, 'the angles of the Vs gradually flattening toward the stern.
2. 'A boat hull having a Vshaped portion intermediate of two inverted V-shaped portions extending substantially the entire length of the hull, the angles of the Vs progressively flattening from an intermediate portion toward the stern.
3. A boat hull having on its bottom a V- shaped portion intermediate two inverted Vshaped portions which gradually flatten toward the stern, the knuckle and keel lines formed by said portions being in parallel vertical planes.
4. A boat hull having on its bottom a V- 'shaped portion intermediate two inverted V-sha'ped portions which gradually flatten toward 'thes'tern, 'the knuckle and-keel lines formed by said portions being in substan :tially parallel vertical planesand being in the same straight lineat any transverse Section.
5. A boat hull having a tron'vex bottom portion intermediate two concave portions extending substantially the full length of the hull, said portions gradually flattening from an intermediate point toward the stern.
6. A boat hull having on its bottom a longitudinal convex ,portion intermediate two concave portions which gradually fiatten toward the stern, the knuckle and keel lines formed by said portions being in parallel vertical planes.
7. A boat hull having on its bottom a longitudinal *eon-vex portion intermediate two concave portions which gradually fiatten toward the stern, the knuckle-and'*keel lines formed b said portions 'beingin substantially' para lel vertical'planes and being in substantiall the same straight line at any transverse section.
8. A boat hull havinga convex bottom portion intermediate of concave portions extending substantially the full length of the hull and gradually flattening toward the stern, and a propeller functioning under the lowest point of the convex portion in prox imity to the stern.
9. A boat hull having a convex bottom portion intermediate of two concave portions extendin substantially the iull'length of the hull an gradually flattening toward the stern, and a pair of rudders-mounted approximately in line with the ceiltersiof the convex portions and inclined toward the center line of the hull.
In testilnony"whereof, I afiix my signature.
