Year: 1806

page_text: GOULD, BOURNE, & CHAMBER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHESTER
GOULD, of Birmingham, in the County of Warwick, Mechanick, 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 Twenty-fourth
day of June, in the forty-sixth year of His reign, give and grant unto the
said Chester Gould, together with THOMAS BOURNE and WILLIAM CHAMBERS,
both of Birmingham aforesaid, Scale Makers, their exors, adñmors, and assigns,
His especial licence that the said Chester Gould, Thomas Bourne, and
William Chambers, their exors, adiñors, and assigns, should and lawfully might,
during the term of years therein mentioned, make, use, exercise, and vend,
within, England, Wales, and Town of Berwick-upon-Tweed, their Inven-
tion of "A MACHINE OR ENGINE FOR ROASTING MEAT BY THE POWER OF STEAM,
AND FOR OTHER PURPOSES WHERE SMALL POWERS ARE NECESSARY;" in which said
Letters Patent there is contained a proviso obliging the said Thomas Bourne,
William Chambers, and Chester Gould, or one of them, by an instrument in
writing under their hands and seals, or under the hand and seal of one of
them, to cause a particular description of the nature of their said Invention,
and in what manner the same is to be performed, to be inrolled in His
Majesty's High Court of Chancery within ono calendar month after the date
of the said recited Letters Patent, as in and by the same, relation being
thereunto had, may more fully and at large appear..

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Chester Gould, do hereby declare that the said Invention is described and
ascertained in manner following (that is to say):-
Our machine or jack is moved by fire or steam, and is constructed in two
different ways, the first of which is as follows (that is to say):-
We make a vessel or boiler of tin, sheet iron, cast iron, copper, brass, or
other proper materials, commonly about nine inches long, seven inches high,
and six or seven inches wide. Within this vessel or boiler we fit a wheel to
turn freely about its axis; this wheel is from six to seven inches long, according
to the width of the boiler, and six or more inches diameter. It is made in
the form of a common over-shot water wheel, and placed in one of the lower
angles of the boiler, so as nearly to touch the bottom and one end of it. The
fire must be made to apply to that end or corner of the boiler where the
wheel is placed, so that the steam which is made in the corner or angle of
the boiler under the wheel, in its ascent through the water, will lodge under
the buckets of the wheel and move it round till the steam escapes at the top.
In the corner of the boiler under the wheel we fit on apparatus which we call
a conductor; its use is to conduct the steam which is made on the sides of the
boiler under the buckets of the wheel as low down as possible, in order that
it may act on the wheel at a greater distance before it arrives at the top of
the water, where it ceases to act. This conductor is a plate of metal soldered
to the sides of the boiler, about half an inch above the bottom, and parrallel to
it, and extends from the end and sides of the boiler towards the wheel as far
as it can go without touching it. Above this conductor we place in like manner
a second and sometimes a third, at about the distance of half an inch from
each other. The wheel within the boiler gives motion to an upright spindle
which carries on its top a small wheel, which last wheel gives motion to the
meat, as appears by the annexed Drawing. The meat to be roasted is sus-
pended by a chain, and on this chain is a wheel, and above the wheel is a
swivel in the chain. Motion is communicated from the jack to the meat by
a chain acting like a band, as appears from the Drawing. We sometimes
construct steamers after the common manner, to stand on the top of our jacks,
for steaming vegetables and other purposes. In the above described jack
the first or main wheel on which the steam acts is in form of an over-shot
water wheel; but in our second form or construction we make the first or
main wheel after the common form of a spiral wheel, resembling an endless
screw. This wheel we place vertically in a boiler made as above, and convey
the steam under its bottom by conductors as above described. The axis
of this spiral passes thro' the top of the boiler, and carries on its top a

page_text: small horizontal wheel, which receives the connecting chain as in the first form
or construction. These machines may be varied in their form, size, and
proportions, as circumstances may require.
In testimony whereof, I have hereunto set my hand and seal, this
Eighteenth day of July, in the year of our Lord One thousand eight
hundred and six.
A, the jack placed on the left-hand side of the fire.
B, a steamer on the jack for cooking vegetables.
C, a small wheel which will give motion to the meat by means of the
connecting chain D.
D, the connecting chain.
E, a reflector which opens at the back, with a circular crane at the top and
a moveable joint at K, from which the meat is suspended by a chain, swivel,
and wheel; the wheel in this chain must be brought to a level to that in the
jack when in use, in order that the connecting chain may be applied to them
as in the Drawing.
F, a jack without a steamer, placed on the right hand of the fire.
G, a jack without a steamer placed on the right hand of the fire and in
action without a reflector, the meat being suspended from a crane, which is
taken off and put on to the chimney piece occasionally.
H, a jack and steamer placed on the right-hand side of the fire.
AND BE IT REMEMBERED, that on the Eighteenth day of July, in the
year of our Lord 1806, the aforesaid Chester Gould came before our said
Lord the King in His Chancery, and acknowledged the Specification aforesaid,
and all and every thing therein contained and specified, in form above written.
And also the Specification aforesaid was stampt according to the tenor of the
Statute made for that purpose.
Inrolled the Eighteenth day of July, in the year of our Lord One
thousand eight hundred and six.
