I ZS ZZ? amt/1 o WILLIAM MARCUS SIMPSON, OF PORTLAND, OREGON.
MULTIPLE-PROPELLER BOAT.
Specification of Letters Patent.
Patented May 13, 1919.
Application filed. September 18, 1918. Serial No. 254,624.
To all whom it may concern:
Be it known that I, WILLIAM M. SIMPSON, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Multiple'Propeller Boats; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in multiple propeller boats and comprises essentially in connection with the hull of the boat, pontoons held spaced apart from the hull of the boat by downwardly curved arms and containing each an auxiliary propeller.
The invention comprises a simple and efiicient device of this nature having various details of construction, combination and arrangement of parts which will be hereinafter full described, shown in the accompa nying drawings and then specifically defined in the appended claim.
My invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this application and in which:
Figure 1 is a top plan view ,of the boat made in accordance with my invention.
Fig. 2 is a cross sectional view on line 22 of Fig. 1, and Fig. 3 is a side eleva tion.
Reference now being had to the details of the drawings by letter:
A designates the hull of a boat which may be of any suitable size or shape modeled especially for high speed, and contains an electric power plant B. Downwardly curved arms G-are mounted upon either side ofthe hull and each terminates at its outer end in a concaved portion which is fastened to the pontoons E, the said concaved portion being suitably braced as at D, and the arms are reinforced by bracket member G having flaring ends secured to the hull A and to the arms C. An electric motor H is adapted to be placed within each pontoon for the purpose of driving the propellers K mounted upon shafts I one within each pontoon, power being derived from the power plant within the hull A.
By the provision of a boat made in accordance with my invention, it will be noted that the pontoons will act as stabilizers, while accelerating power may be obtained from the motors therein, and by the manipulation of the latter the direction of the boat Ina be quickly controlled.
uitable guns may be mounted upon the hull of the boat and owin to the high speed which may be obtained by the craft same would be especially adapted for a submarine chaser.
What I claim to be new is:
A multiple propeller boat, comprising a hull with downwardly curved arms having flaring ends secured to the opposite sides of the boat, brace members having flaring ends fastened to said arms and to the hull, the outer ends of the arms having concaved braced portions, pontoons secured to said concaved portions of the arms, a motor within each pontoon, and a propeller connected to each pontoon and driven by said motors, apower plant within the hull, and electrical connection between the same and the motors in the pontoons.
In testimony whereof I hereunto afix my signature in presence of two witnesses.
WILLIAM MARCUS SIMPSON.
