Year: 1861

page_text: PROVISIONAL SPECIFICATION left by the said Thomas Shutt Stock,
Joseph Sharp Stock, and Henry Taylor, at the Office of the Commis-
sioners of Patents, with their Petition, on the 2nd September 1861.
We. THOMAS SHUTT STOCK and JOSEPH SHARP STOCK and HENRY TAYLOR,
all of Birmingham, in the County of Warwick. Manufacturers and Copart-
ners. do hereby declare the nature of the said Invention for "A NEW OR
IMPROVED TAP OR STOP-COCK," to be as follows:--
The opening and closing of the water-way in the said tap or stop-cock is
effected by a valve which is pressed upon and lifted from its seat by means of
a rod. to which rod the handle of the tap gives motion by means of a crank
[Price Sd.]

page_text: or excentric. The parts of the said tap or stop-cock are constructed and
arranged in the following manner:--In the barrel of the tap is an axis which
may be turned by a handle or thumb plate, at its top the said axis works in a
stuffing box in the said barrel, and carries at its lower end a small crank or
excentric which occupies and works in a chamber at the bottom of the said
barrel. A rod is jointed to the said crank or excentric. which said rod is
made to move backwards and forwards nearly in the axis of the water-way by
turning the handle of the tap or stop-cock. A valve having an india-rubber.
or leather, or other clastic washer is fixed on the end of the said rod, or a
spherical valve may be used, in which case no washer will be required. To
the water-way of the tap or stop-cock a valve seat is made, on which the said
valve is pressed when the handle of the tap is in one position, and from which
it is lifted when the handle is made to perform a semi-rotation. The position
of the valve upon the rod may be adjusted by means of a screw and screw nut.
The valve opens against the current of the liquid, and when the valve is upon
its seat the pressure of the liquid tends to hold it down to its seat. The said
new or improved tap or stop-cock may be used with liquids or steam or other
vapour and gases.

said Thomas Shutt Stock, Joseph Sharp Stock. and Henry Taylor, Her
special licence that we, the said Thomas Shutt Stock, Joseph Sharp Stock.
and Henry Taylor, our executors, administrators, and assigns, or such others
as we. the said Thomas Shutt Stock. Joseph Sharp Stock. and Henry Taylor.
our executors, administrators, and assigns, should at any time agree with.
and no others, from time to time and at all times thereafter during the term

page_text: therein expressed, should and lawfully might make, use, exercise. and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "A NEW OR IMPROVED TAP OR
STOP-COCK," a communication to us from abroad by Allen Hill, of New Orleans,
in the United States of America, upon the condition (amongst others) that we,
the said Thomas Shutt Stock, Joseph Sharp Stock. and Henry Taylor. our
executors or administrators, by an instrument in writing under our or their
hands and seals, or under the hand and seal of one of us or them. should
particularly describe and ascertain the nature of the said Invention. and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Shutt Stock, Joseph Sharp
Stock, and Henry Taylor. do hereby declare the nature of the said Inven-
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof. that is
to say:
The said Invention consists of a tap or stock-cock in which the water-way of
the said tap or stop-cock is opened and closed by a valve which is pressed
upon and lifted from its seat by means of a rod, to which rod the handle of
the tap gives motion by a crank or excentric, as herein-after more particularly
explained and illustrated in the accompanying Drawing.
Figure represents in side elevation. and Figure 2 in vertical section, a
tap or stop-cock made according to the said Invention, the several parts of the
said tap or stop-cock being in the positions which they respectively assume
when the tap or stop-cock is closed: Figure 3 is a vertical section. and
Figure 4, a plan of the said tap or stop-cock. showing the positions which the
several parts respectively assume when the tap is opened. that is, when the
valve is lifted from its seat, and liquid. steam. or gas can pass through the tap.
The other Figures of the Drawing represent parts of the same. as herein-
after explained. The same letters of reference are used to indicate the same
parts in the several Figures of the Drawing.
The body of the tap is made in two parts, marked a. b. (shown separately
in Figures 5 and 6). the part a forming the exit pipe and stuffing box. and
the part b forming the entrance pipe to the tap, as is well understood. In
the stuffing box c is an axis d, which is turned by a handle e at its top. The
axis dis shown separately in elevation in Figure 7. and the handle e and the
screw by which it is fixed to the said axis are shown separately in Figures 8

page_text: and 9. The said axis d works in a plug or tightening piece (shown sepa-
rately in Figure 10) screwed into the stufling box c, and carries at its lower
end a small crank or excentric g which works in a chamber below the stulling
box, as represented in the Drawing. The axis carrying the crank or
excentric has an annular shoulder which bears upon and works against
the support at the bottom of the stufling box c, and the end of the said
axis d. below the crank or excentric g bears and slides upon the part of the
tap is a rod connected to the crank or excentric by the end of the crank or
excentric being dropped into a hole in the said rod. the said end of the crank or
excentric working loosely in the said rod; I is a valve, made of india-rubber,
leather, or other elastic material, fixed on the free end of the rod k by the
cup-like metallic piece m and screw nut n, the said screw nut screwing upon
the screwed end of the said rod k. By means of the metallic piece m and
screw nut n the position of the valve upon the rod k can be adjusted. The
rod and parts connected therewith are shown separately in elevation in
Figure 11 and the said rod without the valve and cup-like piece is shown
separately in plan and side elevation in Figure 12. The valve is shown
separately. in elevation and section in Figure 13, and the cup-like piece m
is shown separately in elevation and section in Figure 14. By turning the
handle e of the tap through a semi-rotation in one or other direction. the rod k,
by the axis d and crank or excentric g. is made to move backwards or forwards
nearly in the axis of the water-way, and the valve on the said rod is thereby
pressed against or lifted from the valve seat o and the tap opened or closed.
'The respective positions of the parts of the tap, when the handle is brought
into one or other position so as to press the valve against or raise it from its
seat, are clearly shown in the sections, Figures 2 and 3. The valve opens
against the current of the liquid, and when the said valve is upon its seat », as
in Figure 2. the pressure of the liquid tends to hold it down to its seat. In
place of an india-rubber or other elastic valve a metal valve, with or without
an india-rubber. leather. or other elastic washer, may be employed. The said
new or improved tap or stop-cock may be used with liquids or steam or other
vapour or gases.
Having now described the nature of the said Invention and the manner in
which the same is to be performed. we wish it to be understood that we do
not limit ourselves to the precise details herein described and represented in
the accompanying Drawing, as the same may be varied without departing
from the nature of the said Invention; but we claim as the said Invention, a
cap or stop-cock in which the valve is pressed against and lifted from its scat

page_text: by a crank or excentric actuated by the handle of the tap. essentially as
herein-before described and illustrated in the accompanying Drawing.
In witness whereof, we, the said Thomas Shutt Stock and Joseph Sharp
Stock and Henry Taylor. have hereunto. set our hands and seals, this
Fourteenth day of February, in the year of our Lord One thousand
eight hundred and sixty-two.
