London, Consulting Engineer, for the Invention of" AN IMPROVED MECHANICAL
VALVE TO BE APPLIED TO BOATS IN LIEU OF THE PLUG OR CORK NOW IN USE,

PROVISIONAL SPECIFICATION left by the said James Casey at the Office
of the Commissioners of Patents on the 25th July 1879.
JAMES CASEY, of Number 10, Philpot Lane, in the City of London, Consulting
Engineer. "AN IMPROVED MECHANICAL VALVE TO BE APPLIED TO BOATS IN LIEU
OF THE PLUG OR CORK NOW IN USE, AND IN ORDER TO SECURE THE SAFETY OF
HUMAN LIFE.”
The employment of a valve fitted to the inside of a boat over the hole or aperture
in which a cork or plug is usually placed. Such Invention consists of a sectional
valve inclosed in a box in which the said valve works, and is fitted over the hole
or aperture aforesaid, which valve can be opened or shut by the action of the hand
or foot applied to a lever so as to prevent the ingress of water when desired, and to
permit the egress of water when necessary. The valve can be opened so as to allow
the water to drain from the boat when the boat is taken from the water. Such
valve can be made of metal or any other substance.

JAMES CASEY, of No. 10, Philpot Lane, in the City of London, Consulting
Engineer. "AN IMPROVED MECHANICAL VALVE TO BE APPLIED TO BOATS IN LIEU
OF THE PLUG OR CORK NOW IN USE, AND IN ORDER TO SECURE THE SAFETY OF
HUMAN LIFE."
This Invention relates to an improved plug or valve chiefly for the better security
of ships' boats, and of the lives of persons using the same, and as a substitute for
the common plug or cork used at present in ships' boats for the closing and opening
of the aperture therein, adapted to allow the egress of water when suspended from
the ship's davits, or when otherwise not in use or not afloat. And in order that my
said Invention may be readily understood I will proceed to describe the same by
reference to the annexed Drawings, wherein similar letters of reference indicate
similar parts in all the Figures.
Figure 1 is a side elevation of the valve of my Invention; c, c, c, and c are the
apertures in the lower part or body F of the socket portion of the valve, and also
those in the top part or cap or cover G thereof; D is the ball valve proper, and
D' the lever for actuating the same, the latter being attached to and in one with the
former. In this Figure the lever D¹ is shown down or depressed, and the valve
closed.
Figure 2 is a plan of the valve illustrated in Figure 1, and shews the flange E
on the lower part or body F of the socket portion of the valve for securing the
same to the boat.
Figure 3 is a similar plan to that shewn in Figure 2, but with the valve D open,
and the upper part or cap or cover of the socket portion G of the valve removed,
and the valve proper D in its seat, but with its lever D' cut off, the position
occupied by the lever when down being indicated in dotted lines.
Figure 4 is a sectional elevation of the view shewn in Fig. 3, taken through the
same at A, A, and illustrates the valve open; the socket portion F and G of the
valve and the flange E for attachment are in section, and the valve proper D and
the lever D¹ are in elevation.
Figure 5 is a section of the valve on the line B, B, (Figure 3) with the valve
closed, and shews more clearly the apertures C, C, C, C, and C₁, and the cavities
formed between the ball proper D and its socket.
Figure 6 is a similar section of the valve to that shewn in Figure 5, but with the
valve open, and illustrates the manner of egress and ingress through the valve by
means of the cavities in the ball valve D and apertures C, C, and C³.
My Invention consists of a valve of metal or other suitable material secured by
means of screws or bolts to the inside of the boat and over the hole in the bottom,
where the plug or cork now in use is inserted, the said valve being made with a
hole C¹ corresponding to the hole in the planking of the boat. This valve is in
construction of a ball and socket kind, the valve proper being a ball D moving in a
socket as its seat, and in the lower half or body F of the latter there is, firstly, a
centre hole C¹ corresponding with the hole in the boat, and placed over the same;
and, secondly, openings or apertures C, C, C, and C in the socket portions or body
and cap of the valve for egress or ingress of water or other liquid from or to the
boat. The ball valve D has two segments cut off it so as to leave two cavities
between it and the socket or seat in which it moves; and the two cavities are so
located and inclined to each other that when the lever D¹ actuating, the same is in
a vertical position these two cavities (made by the removed segments of the ball
give free communication between the apertures C¹ in the bottom of the valve and
these C, C, C, and C in the sides of the socket portions or body and cap parts of

page_text: the valve, and in this manner egress and ingress for water or other fluid is obtained
through the valve from and to the boats. When the lever D¹ is pressed down it
removes the cavities in the ball from the vicinity of the central opening C¹, and
bring the rounded part of the ball or that portion which has its true spherical
surface over the lower centred aperture, and thus effectually closes or shuts that
opening to the passage of water or other liquids.
The cap or cover G has a suitable slot in one side of it to allow the lever D' of
the valve D to be raised and depressed as required; the cap is secured to the body
or lower part of the socket portion F of the valve by the screws F', as shewn.
The lever D' of the valve D can be actuated by hand, foot, or otherwise.
Having thus described the nature of my said Invention and in what manner the
same is carried into effect, I would observe in conclusion that valves made according
to the principle of my Invention may be applied to and are applicable for the
passage of other liquids, gas, or steam, and other useful purposes, and that what I
claim under tbe hereinbefore recited Letters Patent is,-
The combination and arrangement of apparatus and mechanism together forming
my improved mechanical valve, substantially as and for the purposes hereinbefore
described and shewn in the Drawings, Figs. 1, 2, 3, 4, 5, and 6, or any mere modi-
fication thereof.
In witness whereof, I, the said James Casey, have hereunto set my hand and
seal, this Twenty second day of January, in the year of our Lord One
thousand eight hundred and eighty.
