VESSEL.
SPECIFICATION forming part of Letters Patent No. 580,023, dated April 6, 1897.
Application filed July 23, 1896. Serial No. 600,299. (No model.)
To all whom, it may concern; Within the vessel are placed one or more Be it known that I, CLARENCE TERRY generators B B, steam-generators being in \VENTZ, a citizen of theUnited States, residthis instance shown.

- flumes are shallow and narrow at their forward ends, but are deeper and wider as they extend rearwardly. A wall K determines their length and also forms the front of a larger flume or chamber L, into which the smaller flumes I I discharge. The chamber L converges toward its rear end and gradually tapers off into the general lines of the hull. The propellershaft H is carried in suitable journals mounted in the rib J, the end of the shaft projecting into the chamber L through a stuffing-box placed in the wall K. It will thus be seen that the screw-propeller works within the chamber L and does not project beyond the side of the vessel. Its power or efficiency is not, however, affected, for by the use of the flumes the propeller has at all times sufficient water upon which to work.
A manhole M affords communication from the interior of the vessel to the chamber L.
N denotes a shield or cover, preferably formed of sheet-steel, designed to be placed over the flumes and the propeller whenever it is desired to have access thereto. When the cover or shield is in the position indicated on the left side of Fig. 3, the flumes I I and the chamber L are covered, after which the water may be drawn from the compartment thus formed and the propeller inspected and repaired, if necessary. This may be accomplished without stopping the vessel under the construction employed and designed by me.
The shield or cover N is hinged to a crossbar 0, said bar having on its rear face near each end a T- shaped head or projection P. These heads are designed to fit and move in guides or ways Q, formed in the side of the vessel and extending down to a point just above the flumes.
Any suitable means may be employed for raising and lowering the cross-bar and the shield or cover. In the drawings I have shown two eyebolts or plates designed to be connected with any form of hoisting means that may be convenient.
'Upon the shield N, I secure a number of blades or wings R. They are pivotally mounted between two horizontal arms or brackets S, the lower one being formed with a stop a, designed to be engaged by a corresponding stop 1) upon the wing or blade. This is to prevent the blades or wings from swinging too far out from the cover, the extreme position being shown in Fig. 5 and on the right of Fig. 3.
The rods upon which the end blades are pivoted extend up through the upper brackets or arms S and terminate in cranks T. The pivot of the central blade extends up to the top of the cover or shield N, where itis c011- nected through the agency of a universal joint U to a shaft V, journaled on the crossbar 0. A projection-arm IV is also formed on the pivot of the central blade, and this arm W is connected to the cranks T by a rod or bar X.
The upper end of the shaft V is squared and may be turned 'by a crank Y or other suitable means.
Ordinarily the shields or covers will be maintained in an elevated position, as shown in dotted lines in Fig. 3, but should it be necessary to inspect or repair any one of the propellers the shield or cover immediately over it would be lowered and a water-tight compartment formed over the propeller, to which access could be had through the manhole M. To do this, the shield would be lowered to the position shown in full lines in the left of Fig. 3. The tendency of the shield would be to float out on the wateror to assume a nearly vertical position, but to force it to its place over the flumes the blades R are inclined inwardly, as shown on the left of Fig. 3, and as the vessel proceeds forward the cover or shield will be forced down over the flumes and the propeller by the action of the external water on the shield R, forming a watertight compartment, which will be maintained so long as the blades incline in toward the shield.
\Vhen it is desired to elevate the shield, the blades are turned outwardly and the cover will rise and assume the position indicated on the right of Fig. 3. Of course if the vessel were backing the positions of the blades would be reversed from those just set forth.
By the proper control of the rear pair of propellers or by the change of speed of the screws upon one or the other side the vessel may be turned with great facility.
Having thus described my invention, what I claim is- 1. In a vessel or ship, the combination of two flumes or ways formed in the side thereof and directly open throughout their length to the water; a rib formed by, and intermediate of said flumes; a third flume in rear of the other'fiumes, and also directly open to the water; and a propeller mounted within the third flume.
2. In a vessel or ship, the combination of two flumes or ways formed in the side thereof and directly open throughout their length to the water, said flumes widening toward their rear end; a third flume or chamber located in rear of the other flumes and converging toward its rear end, said chamber being also directly open to the water; and a propeller working within the forward part of the chamber.
3. In a vessel or ship the combination of two flumes formed in the side thereof and widening toward their rear end; a chamber or third flume located in rear of the other flumes and converging toward its rear end; a propellershaft mounted within the rib intermediate the front flumes; and a propeller mounted on the shaft and working in the rear flume.
4. In a vessel or ship, the combination of two flumes or ways open throughout their length to the water; a third flume also directly open throughout its length located in rear of said first flumes and into which they discharge; a propeller Working in the rear fiume; and a movable covering or shield for said flumes.
5. In a vessel, the combination of a recess or compartment formed in its side; a propeller mounted therein; a cover or shield designed to close said compartment; and means carried by said cover or shield for causing it to close by the movement of the vessel.
6. In a vessel, the combination of a recess or compartment formed in its side; a propeller mounted therein; a cover or shield designed to close said compartment; and means carried by said cover or shield for causing it to close and to hold it in its closed position by the movement of the vessel.
7 In combination With the hull and a compartment formed in its side; a propeller mounted in said compartment; guides or Ways formed in the hull contiguous to the compartment; a shield or cover guided by said Ways; and means carried by said cover for causing it to close down and to be held in its closed position by the movement of the vessel.
8. In a vessel, the combination of a recess or compartment formed in its side; a propeller mounted therein; a cover or shield designed to close said compartment; and adjustable means carried by said cover or shield for causing it to close and open by the movement of the vessel.
9. In combination with the hull and a compartment formed in its side; a propeller mounted therein; guides formed in the hull contiguous to the compartment; a cross-bar provided with arms Working in the guides; a shield or cover hinged to said cross-bar; a series of blades pivoted to the shield; and means for turning said blades at varying angles to the shield.
10. In combination with the hull and a compartment formed in its side; a propeller mounted therein; guides or Ways formed in the hull contiguous to the compartment; a cross-bar provided with arms Working in the .Ways; a shield or cover hinged to the crossbar; a series of blades pivoted to the shield at a distance therefrom; means for turning said blades at varying angles to the shield; and a stop to limit their outward movement.
11. In combination with the hull of a vessel; a compartment formed therein; a shield or cover hinged to a vertical moving guide; and means carried by the shield for causing it to swing up or down as desired.
In witness whereof Ihereunto set my hand in the presence of two Witnesses.
