WATER-CRAFT.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application led February 20,1905. Serial No. 246,610.

T all whom it may concern:

Be it known that we, ARTHUR J. SUI-IM and EDGAR A. Soi-IM, citizens of the United States, residing at Milwaukee, county of Milwaukee, and State of lVisconsin, have invented new and useful improvements in lVater-Craft, of which the following is a specification.

Our invention relates to improvements in that class of sailing-craft in which a plurality of hulls are employed.

The object of our invention is to provide a form of construction in which the several hulls are connected with and contribute to support a rigid carrying frame or deck, each hull being free to oscillate over the waves on a horizontal pivot and all of the hulls being connected in such a manner that they may be simultaneously turned on vertical pivots for steering purposes, the front and rear hulls being arranged to turn in opposite directions, whereby stability is secured and the movement of the craft readily and quickly controlled.

In the following description reference is had to the accompanying drawings, in which-- Figure 1 is a plan view with the deck broken away to show the arrangement of the hulls, steering connections, and stays. Fig. 2 is a front elevation. Fig. 3 is a side view, on a reduced scale showing the relation of the sail when used.

Like parts are identified by the same reference characters throughout the several views.

1 is a carrying frame or deck provided with a beam 2 and a mast 3. The deckframe is supported from a series of hulls 4, 5, and 6, the hulls 4 and 5 being located underneath the ends of the beam 2 and the rear hulls 6 being located under the longitudinal center line of the deck near its rear end. The hulls 4 and 5 are each provided with an inwardly-projecting steering-arm 10, which preferably, also, constitutes a horizontal pivot-shaft 1 1 for the hulls. Each of the hulls is provided with upwardly-projecting bearing members 12, in which the pivot-shaft 11 is journaled, the shaft being also journaled in downwardly-projecting bearing members 13, connected with a rotary disk or wheel 14, which supports and turns upon a stationary disk or wheel 15, the latter being rigidly connected with the deck 1 and beam 2. A central vertical pivot -bolt 16 connects the wheels 14 and 15, whereby the hulls are permitted to oscillate not only on the horizontal pivot-shaft11, but also on the vertical pivot bolt or shaft 16, the wheels 14 and 15 serving as a turn-table and providing a broad bearing which relieves the vertical pivot-bolt of the strain, which would otherwise be exerted upon it. The rear hull is provided with a horizontal pivot-shaft 20, similar to the shaft 1 1, and with arms 21, projecting laterally on both sides thereof and which are preferably extensions of the pivot-shaft. This hull is also provided with turn- table wheels 14 and 15 and bearing members 12 and 13, whereby the hull is connected with thevdeck and permitted to oscillatc upon a vertical pivot-bolt 16 in the same vmanner as above described with reference to the hulls 4 and 5. steering-wheel is preferably connected with the vertical pivot-bolt 16 of the rear hull. A lever 27 is preferably pivoted to the front of the beam 2S. The outer ends of this lever 27 are connected with the inner ends of the arms l() and with the outer ends of the arms 21, whereby the motion of the steering-wheel 25 is communicated simultaneously to each of the hulls.

It will be observed that the connections are so made that when the arms 10 of the hulls 4 and 5, respectively, are in lineal alinement all the hulls will occupy positions parallel with the longitudinal center line of the craft. By moving the lever 25 to the right, as indicated by dotted lines in Fig. 1, the two forward hulls will be swung to the right, while the rear hull will be swung to the left, thereby causing the craft to turn toward the right. A left-hand turn will of course be made by swinging the lever 25 in the opposite direction.

The outer ends of the hulls 4 and 5, respectively, are preferably connected by stays 30 with the inner ends of the levers 10, and, if desired, the pivot-shafts 11 may be extended beyond the hulls for the attachment of outer stays 33, as clearly shown in Fig. 1. Stays are employed to connect the front and rear ends of the hull 6 with the arms 21. The object of the stays is to relieve the strain IOO upon the hulls in passing over the waves and when steering.

In the drawings a mast 3 is shown stepped in the forward central portion of the deck and beam 2.

Any suitable form of sail may be used, or, if desired, the sail may be dispensed with and other motive power employed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, isu 1. Inadevice of the described class, the combination of a rigid deck-frame, a set of hulls supporting said frame; connections between the hulls and frame adapted to permit the hulls to swing on both vertical and horizontal axes; and connections between the hulls adapted to communicate their horizontal movement from one to the other; said connections being arranged to move the front and rear hulls in opposite directions.

2. In a device of the described class, the combination of a rigid deck-frame; a set of hulls supporting saidframe connections between the hulls and frame adapted to permitl the hulls to swing on both vertical and horizontal axes and flexible connections between the hulls, each attached to the opposite side of -a front hull from that of its atsaidfra'me;y connections between the hulls and frame adaptedto permit the hulls to vswing Von both vertical and horizontal axes rigid steering-arms extending inwardly from each of the forward hulls and outwardly at both sides of the rear hull and connections j extending from the arm of each forward hull to the'arm 'projecting from the opposite side v'of the rear hull.
