AN IMPROVE- MENT UPON COCKS, OR AN IMPROVED LOCK Cocк
Year: 1810

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
FROST, of Little Sutton Street, Clerkenwell, in the County Middlesex, Brass
Founder, and JAMES FROST, the younger, his Son, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of June, in the fiftieth year of His
reign, did give and grant unto us, the said James Frost, and James Frost
the younger, His special license that we, the said James Frost, and James
Frost the younger, during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within that part of the United
Kingdom of Great Britain and Ireland called England, the Dominion of
Wales, and Town of Berwick-upon-Tweed, our Invention of "AN IMPROVE-
MENT UPON COCKS, OR AN IMPROVED LOCK Cocк;" in which said Letters Patent
there is contained a proviso, obliging us, the said James Frost, and James
Frost the younger, under our hand and seal, to cause a particular descrip
tion of the nature of such Invention, and how the same is to be performed, to
be inrolled in His Majesty's High Court of Chancery within two calendar
months next after the date of the said recited Letters Patent, as in and

page_text: by the same, relation being thereunto had, may more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
James Frost, and James Frost the younger, do hereby declare that the nature
of our said Invention, and the manner in which the same is to be performed,
are particularly described and ascertained as follows, that is to say:
Instead of making the pin or revolving piece of our improved lock cock
solid throughout, excepting that part in which the aperture or channel or
perforation through which the liquid or fluid is intended to pass, we do make a
cavity in the upper part of the said pin or revolving piece, and the socket into
which the said pin or revolving piece is fitting by turning and grinding, and in
the cavity so made we do dispose and fix a lock having a bolt, and the other
parts usually constituting such locks as operate by means of a bolt, and we do
throw the said bolt backward or forward by a motion at right angles to the
axis of the said pin or revolving piece by the action of a key or other similar
instrument, in order that when the said bolt shall be protruded or shot out of
its cell in the manner of locking, part of the said bolt shall stand forward
beyond the face of the said pin or revolving piece, and shall enter into a cavity
or cell in part of the motionless socket into which the said pin or revolving
piece is disposed or placed, and shall thereby render the said pin or revolving
piece itself also motionless, and shall make it impractible to turn or open the
cock until the bolt shall been first shot back by means of its key. And we do
so place or dispose the said bolt in its own cavity or cell; and we do make the
aforesaid cavity or cell in the motionless socket in such manner and positions
with regard to each other that the waterway or course through the cock shall
be shut whenever the said bolt is or shall be protruded in the manner of
locking into the said motionless socket, and shall not be capable of being
opened until the said bolt is or shall be unlocked or withdrawn; and farther,
we do declare that our said improvement upon cocks by, through, or by means
of which we have distinguished such cocks by the denomination of improved
lock cocks, may be applied to cocks of various kinds and descriptions, and to
the lower as well as, or instead of, to the upper part of the said pin or revolving
piece, and the said bolt may also, when preferred, be made to shoot or lock
into a fixed or motionless piece proceeding from the vessell or receptacle in
which any liquor or fluid is to bo guarded and secured by our said improve-
meuts, as well as into a fixed or motionless piece, such as is herein before
described, and that the ellects of the last-mentioned disposition and application
of the bolt with regard to the said vessell or receptacle will be such as not only

page_text: o prevent the before-mentioned pin from revolving with regard or in relation
to the cock itself, but likewise to prevent the said cock whilst locked from
being unscrewed or drawn out of the before-mentioned vessell or receptacle.
In witness whereof, we, the said James Frost, and James Frost the
younger, have hereunto set our hands and seals, this Seventh day of
August, in the fiftieth year of the reign of our Sovereign Lord George
the Third, and in the year of our Lord One thousand eight and
ten.
