Year: 1805

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
Pocock, of the Parish of Saint Paul, Covent Garden, in the County of Middle-
sex, Cabinet Maker and Upholsterer, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Nineteenth day of
November, in the forty-sixth year of His reign, give and grant unto me, the
said William Pocock, my executors, administrators, and assigns, His especial
licence, that I, the said William Pocock, my executors, administrators, and
assigns, should and lawfully might, during the term of years therein mentioned,
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed my Invention of "AN IMPROVEMENT ON TABLES FOR DINING
AND OTHER USES;" in which said Letters Patent there is contained a proviso,
obliging me, the said William Pocock, by an instrument in writing under my
hand and seal, to cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled
in His Majesty's High Court of Chancery, within one calendar month after
the date of the said recited Letters Patent, as in and by the same, rela-
tion being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Pocock, do hereby declare, that my said Invention for the improve-

page_text: ment of tables for dining and other uses, which I term simpathitce, is described
in manner following, (that is to say):-
I cause both ends or opposite parts of a table or table frame to receed from
or approach towards each other and their common centre by equal or nearly
equal degrees of motion and distance by applying the hand or moving power
to either of the ends, and thereby prevent the necessity of applying the hand or
moving power to both ends, at one and the same time, when a double motion
is required; and this double motion I produce by various ways and methods,
as the length or strength of the motion may require, either by lines, or chains
and pullies and rollers, or cogs and wheels, and racks, and rollers, or any other
convenient way as are more fully described in the above Drawing and the
following description thereof.
First, I make a frame or a support, on which I fix two rails, as A, A, in
which rails A, A, I place two or more pullies as h, h, or I, I, at such distances
as best suit the length of motion required, as in Fig. 1; if I require a long
motion I place my pullies at or near each end of the fixed rails A, A, as at
h, h, if I require a shorter motion I placo my pullies near the center of tho
fixed rails A, A, Fig. 1, as at I, I, and so at various other distances, as
occasion may be or require. I also make a frame to pass within or between
the two fixed rails A, A, as b, b, and also I make a frame to pass on the
outsides of the two fixed rails A, A, as c, c, to which frames b, b and c, c; I fix
the lines or chains d, d, d, d, after I have passed them through or over tho
pullies h, h, or I, I, in the fixed rails A, A, and fastened them to the frames
b, b, and c, c, at F, F, F, F, F, F, which on pulling the handle E will cause
the frame C, C to move in a contrary or opposite direction to the frame B, B,
and on pulling the handle G will cause the frame B, B, to move in a contrary
or opposite direction to the framo C, C; and also where more strength or
duration is required, instead of the lines or chains and pullies I make and
place in the two fixed rails A, A, two wheels with cogs, made of brass, iron, or
any other suitable metal, as M, M, in Fig. 2, and on the sides of the frames
N, N, N, N, I place a rack with cogs as 0, 0, 0, 0, of the same material as
the wheels or any other, that may be more suitable, which racks O, O, being
shaped to suit and placed in contact with the cog-wheels M, M, on pulling the
handle or will produce the same motion, as before described to be pro-
duced by pulling the handles E and G in Fig. 1.
In witness whereof, I, the said William Pocock, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of our
Lord One thousand eight hundred and five.
WILLIAM POCOCK. (L.S.)
