Specification of Letters Patent.
Patented Nov. 1-4, 1905.
To (TI/ll whom, 7125 may concern:
Be it known that I, LsAAo E. PALMER, acitizen of the United States, andaresident of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Hull of Vessels, of which the following is a specification.
Myinvention relates to thehulls of vessels, with the object in view of materially reducing the tendency of the hull to pitch or roll inseaway and at the same time to provide a guard for the propelling-wheel either in power or auxiliary craft and to provide for increasing the effectiveness of the wheel.
My present application includes the subjectmatter of my former application, Serial No. 188,707, filed January 12, 1904, allowed July 16, 1904, and formally abandoned under date of December 21, 1904, in favor of the present application.
A practical embodiment of rnyinvention is represented in the accompanying drawings, in which- Figure 1 represents in side elevation the stern portion of a power-boat arranged with double-screw wheel-propeller. Fig. 2 is a bottom plan view of the same. Fig. 3 1s a transverse section of the same in the plane of the line A A of Fig. 1. Fig. 4 is a view in side elevation oi the stern portion of an auxiliary craft with single propeller. Fig. 5 is a bottom plan view of the same. Fig. 6 is a view of the same in transverse section in the plane of the line B B of Fig. 4. Fig. 7 is a view in side elevation of the stern portion of the hull of a sailing craft. Fig. 8 is a bottom plan view of the same. Fig. 9 is an end view of the same. Fig. 10 is a view in side elevation of the stern portion of a singlewheel power-boat with bilge-heels. Fig. 11 is a bottom plan view of the same. Fig. 12is an end view of the same. Fig. 13 is a view in side elevation of the stern portion of a single-wheel power-boat with bilge-heels overlapping the outer edges of the wings on the outside. Fig. 14 is an end View of the same, and Fig. 15 is an end view showing the billgekeels overlapping the wings on the insic e.
Referring to Figs. 1, 2, 3, the body of the hull is denoted byl. In Figs. 4, 5, and 6 the body of the hull is denoted by 2, and in Figs. 7, 8, and 9 the body of the hull is denoted by 3. In each one of the several forms shown there is provided, underneath the stern portion and spaced from the body of the boat a pair of laterally-extended wings. These wings in the form shown in Figs. 1 to 3, inclusive, are denoted by4 and 5; in the form shown in Figs. 4 to 6, inclusive, by 6 and 7, and in the form shown in Figs. 7 to 9, inclusive, by 8 and 9.
The members of a pair of wings may be formed separately and rigidly secured together, or the two wings may be formed in a continuous piece. They may either be curved, as shown in Figs. 1 to 3, inclusive, each wing being curved independently of its companion wings, or they may be formed in a continuous curve, as shown in Figs. 4 to 6, inclusive, or they may lie in a horizontal plane, as shown in Figs. 7 to 9, inclusive, or they may curve downwardly, as shown in Figs. 10 to 12, inclusive, or their outer edges may turn upwardly, as shown in Figs. 13 to 15, inclusive. They preferably narrow .gradually as they extend toward the bow of the hull and reach their extreme width when used in connection with a propeller at a point immediately below the propeller, their rear portions being rounded off in a fair line.
In the form shown in Fig. 1 the hull is provided with a central keel 10, to which the pair of wings 4 and 5 is secured, and the bilges of the hull are provided near the stern portions of the hull with arched channels 11 and 12, along which the water flows into con tact with the propellers 13 14, the wings 1 and 5 serving to partially inclose the channels 11 and 12 at the point where the pro pellers operate, but leaving at the same time an opening for the water to escape from the propellers outwardly as well as rearwardly.
In the form of hull shown in Figs. '1 to 3, inclusive, the extreme stern portion of the hull is carried out on a horizontal line,as shown at 15, to prevent the hull from squatting, as it is commonly called, when under high speed.
Where a single propeller is employed, as shown in Figs. 4 to 6, inclusive, the stern portion of the hull is provided with an arched channel 16, the keel 17 occupying a central posiarranged where they protect the rudder and where their effect in preventing pitching will be most pronounced. They also help to hold the boat up to the wind.
In the form shown in Figs. 10 to 12, inclusive, the downwardly-curved wings 19 20 coact with the bilge keels or blades 21 22 to hold the water to the wheel, and the wings 23 2a, in Figs. 13 to 15, coact with the overlapping bilge-kecls 25 26 to hold the water to the wheel, while at the same time space is left for it to escape laterally. The horizontally-extended plate 27, Fig. 13, like the horizontal extension of the hull 15, Fig. 1, serve to prevent the squatting of the stern.
In operation any tendency of the stern to lift will be opposed by the body of water above the wings, while any sudden tendency of the stern of the boat to squat or lower will be likewise opposed, and the sudden pitches which are commonly experienced in sharp seas will be materially modified because of the retarding effect which this horizontal plane or pair of wings will exert.
WVhile presenting a formidable opposition to the sudden lifting or depressingof the stern of the vessel, the plate or Wings will present but little obstruction to the forward movement of the hull and will at all times be an important factor in warding off damage to the wheel and rudder in connection with power and auxiliary craft and from the rudder in sailing craft.
In all the forms shown the wings vanish into the keel of the vessel as they extend forward and permit a free flow of water over them to the wheel, and the water after being acted upon by the wheel may escape laterally as well as rearwardly.
It is obvious that changes might be resorted to in the shape and extent of the plate or wings and that their position with respect to the body of the hull may be changed without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein shown and described; but
What I claim is 1. The combination with the hull of a vessel, of laterally-extended wings fixed to the keel of the vessel at the stern portion thereof and spaced from the bottom of the vessel upon opposite sides of the keel, the said wings constructed to vanish into the keel of the vessel as they extend forward.
2. The combination with the hull of avessel provided with a channel at the stern portion thereof, of laterally-extended wings forminga bottom to said channel and spaced from the wall of the channel to leave an opening for the escape of the water laterally from within the channel, the said wings being constructed to vanish into the keel of the vessel as they extend forward, whereby a free flow of water is maintained through the channel.
3. The combination with the hull of a vessel provided with an archedchannel at the stern portion thereof, of laterally-extended wings forming a bottom to said arched channel and spaced from the wall of said arched channel to leave a free opening for the escape of the water laterally from within the channel, the said wings constructed to vanish into the keel of the vessel as they extend forward, whereby a free flow of water is maintained through the arched channel.
4. The combination with the hull of a vessel provided with a plurality of arched channels at the stern portion thereof, of laterally-extended wings extending under said arched channels and spaced from the outer walls thereof to permit the water to escape laterally from within the channels, the said wings being constructed to vanish into the keel as they extend forwardly.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 24th day of August, A. D. 1904.
ISAAC E. PALMER.

PAUL S. CARRIER, CHAS. M. SAUER.
