THE FIRM-NAME 0F TAMS, LEMOINE 8c HYDBOPLANE-BOAT.
Specification of Letters Patent.
Application filed February 19, 1915. Serial No. 93%.
'a citizen of the United States, residing at Hewlett, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Hydroplane-Boats, of which the following is a specification, reference being made to the accompanying drawings, forming a part thereof.
My invention relates to improvements in hydroplane boats which are provided with inclined surface or plane members so secured to the boat as to act on the water when the boat is driven at high speeds, whereby the hull is partially lifted out of the water, thereby reducing the friction of the water upon the boat while running.
The objects of my invention, among other things, are to simplify the construction by diminishing the resisting surfaces, and to so arrange and secure the planes on the under surface of the hull as to obtain a maximum of lifting power with a minimum of friction on the submerged parts of the hull, and, at the same time, to have the plane or several planes, act as horizontal rudders automatically tending to adjust the fore and afttrim of the boatwhen" running at high speeds and in rough water. I attain these objects by mechanism shown in the accompanying drawings in which Figure 1 is a side elevation view of a hydroplane boat equipped with my improved planes; Fig. 2 is an enlarged plan view of the stern of the boat; Fig. 3 is an enlarged plan View, broken, of the lower submerged plane; Fig. e is an enlarged cross-sectional propeller with the two planes; Fig. 11 is a view similar to Fig. 6, showing two rudders; and Fig. 12 is an enlarged view of the modification shown in Fig. 10, the rudder and propeller being omitted.
Similar numerals refer to similar parts throughout the various figures.
Referring to the drawings, 13 is the hull of the boat of any suitable form of construction having the forward plane member 1a secured to the bottom of the hull at such a predetermined angle as to insure the proper lifting of the forward and middle portions of the boat when driven at the customary speed. In the preferred form of construction, I utilize two propellers and a single rudder in my boat, in which 15 and 16 are the propeller shafts to which the propellers 17 and 18 are respectively secured. The two shafts 15 and 16-eXtend rearwardly toward the stern of the boat, which is preferably pointed, as shown in Fig. 2, and are rotatably secured in their respective bearings 19 and 20, as shown in Fig. 6, which bearings are preferably an integral part of the propeller struts 21 and 22 extending vertically downward from the stern into the water, as shown in Fig. 1. The propeller struts 21 and22 are rigidly secured, as shown in Fig. 5, to a triangular frame 23 which may be rigidly secured to the stern of the boat, as shown in Fig. 2, which frame 23 carries the upright rudder post 24 secured at the top and bottom to the apex and base of the frame 23, as shown in Fig. 5. The upper bearing 25 and lower bearing 26 of the rudder post 24. carry the upper and lower ends of the rudder stock 27 to which is secured the rudder 28 of suitable form and construction. The rudder tiller 29 is secured to the top of the stock 27, as shown in Fig. 1, to which are attached the tiller ropes 30 and 31 passing through rollers 32 and 33 respectively, secured to the stern of the boat, as shown in Fig. 2.
The rudder 28 is rigidly secured to the rudder stock 27; and is journaled in the lower bearing 26 of the rudder post 2% andshown in Fig. 5. The form and general configuration of this lower plane member 36 is shown in Figs. 3 and 4, though its size may vary according tothe size of the boat and the maximum speed desired; it is set at a predetermined angle in co-relation with the plane it and is always submerged, being utilized in conjunction with the forward plane 14: not only to raise the after part of the boat, but to act as a horizontal rudder automatically tending to adjust the fore and aft trim of the boat when traveling at high speeds either in smooth or rough water. Since the plane member 36 is always wholly submerged, its action is always positive and predetermined since the angle of incidence can be fixed in accordance with the size, shape and distribution of weights in the after portion of the boat. This novel function results in a smooth running boat without any jumping or pounding which has heretofore occured with the use of plane members that are in and out of the water under varying conditions of wind, water and speed. It Wlll be observed that 1 support this lower plane member on the same struts 21 and 22 which carry the propeller shafts 19 and 20 respectively, thereby doing away with separate supports for the plane and eliminating the resistance friction of such independent supports. Again, by having this plane member 36 wholly submerged under all conditions of running, I am enabled to so construct the after part of the boat as to make a better sea boat than are boats of wide stern construction, as is usual in present hydroplanes, thereby greatly decreasing the weight and resistance surfaces in the water.
In conjunction with the lower plane 36, I may also use an additional upper plane 39 supported on the same propeller struts 21 and 22 as is the plane 36 and preferably at the juncture of these struts with the frame 23 as shown in Fig. 5. This plane 39 may also be secured to the rudder post 24 and its general form and one method of securing same to the rudder post are shown in Figs. 8 and 9. This plane 39 is also set at a fixed angle with the forward plane 14, and acts to support the stern of the boat when starting and running at the lower speeds, but at the higher speeds, this upper plane 39 is wholly clear of the water, thereby permitting the lower or submerged plane 36 to be proportionately reduced in size to suit the maximum speed of the boat. It is apparent that by this improved construction and location of the respective planes the friction surfaces have been reduced to a minimum without loss of lifting power when the boat is running at its maximum, as well as at intermediate, speeds.
In the modifications shown in Figs. 10, 11 and 12, Figs. 10 and 12 show the use of a single propeller and rudder combined with the lower plane 36 and the upper plane 39, both being rigidly secured to the rudder post 24.- as shown in Figs. 10 and 12, while in Fig. 11, 1 have shown the use of two rudders 28 and 28 Fig. 11 being similar to Fig. 6 except that in Fig. 6 a single rudder 28 is illustrated.
