IMPROVEMENT IN DEVICE FOR SCUTTLING- VESSELS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Be it known that I, J oHN HAIIL, of Marsheld, in the county of Plymouth, and State of Massachusetts, havel invented a new and improved Gate for Scuttling Ships; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the saine, reference being had to the accompanying drawings, making a part of this speciiication, in which- Figure l is a vertical section, through the line x of iig. 2.

Figure 2 is a side elevation.

The object of this invention is to construct and at tach to vessels agate, which can readily be opened,. for the piu'pose of scuttling them, and which can aftery ward be as readily closed, when it is desired to pump out and raise the vessel.

In the drawings, A represents a portieri 'of the hull of the vessel, having an opening, a, through which the water is to be admitted, in seuttling the vessel, and D is the deck.

A shorttubeor pipe of metal, O, cast or wrought, is made, and inserted into the opening a, being provided with anges c c', which t tightly against the wall, around the opening a, on both the inside and outside of the vessel, being provided with a central opening, to admit the water. The inner flange c is expanded so as to forni ahed, to support the gate and its guides and stays, and allow the gate to slide up and down, so as to cover or uncover the mouth of the opening a.

The bed, thus for1ned,'is provided with raised anges e e along its sides, which have longitudinal guide-grooves along their inner edge, where they jointhe bed-plate a, in which grooves the gate G slides.

Stays 's s may be employed to strengthen the several parts, in the manner shown in the drawings.

`A rod, R, bent to conform to the wall of the vessel,v

extends from the upper edge of the gate G, through a guide,'g, up toward the deck D, just beneath which it is attached to a vertical screw-rod, by a swivel-j oint, F. rIhe last-mentioned rod, M, extends up through the deck, and terminates in a crank or handle, H.

A plate, P, is attached to the deck, provided with a female screw, through which the male-screw rod M eX- tends. I

By turning the handle H in one direction or the other, the rod M is screwed up or down, carrying with it'the gate G, and opening or closing the aperture af.

The whole device is simple and cheap, and can be operated at any moment from the deck.

-Having thus described my invention,

What lI claimas new, and desire to seclue by Letters Patent, is-

The device above described, consisting essentially of the metallic piece C, having the flanges c o, the
