AN IMPROVEMENT ON FORGES
Year: 1834

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WEST, of Crayford, in the County of Kent, Blacksmith, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Ninth day of December, in the fifth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
John West, His especial licence, full power, sole privilege and authority,
that I, the said John West, my exors, adñiors, and assigns, or such others
as I, the said John West, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the
term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "AN IMPROVEMENT ON FORGES;" in which said Letters
Patent is contained a proviso that I, the said John West, shall 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 said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John West, do hereby declare the nature of my Invention, and the manner in
which the same is to be performed, are fully described and ascertained in and

page_text: hereunto annexed, and to the figures and letters marked thereon (that is to
say) -
:-
My Invention consists in causing water to circulate within the back of the
forge in order to carry off heat therefrom, whereby the back of the forge will
be preserved from the prejudicial effects of the heat, as will be hereafter fully
described.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a front view of a forge back, which is made hollow in
order to admit of a flow of water. Figure 2 is a back view of Figure 1, by
which the position of the circulating pipes is shown. Figure 3 is a side view
of a forge back, and Figure 4 is a side section, by which the action of the
water will become more evident, the arrows in this latter Figure clearly indi-
cating the flow of the water. In each of these Figures the same letters
indicate similar parts. It will be seen that the back of the forge is made up
of the parts a and b, the part a being the front or part against which the fire or
hot coal lies, and is consequently that part which is liable in the ordinary back
to be quickly destroyed; but when constructed in such a manner as to admit of
a constant flow of water against the back surface, this part a will be less predju-
dicially acted on by the hot coal, owing to the heat being constantly conveyed
away by the circulation of the water. The part 6 constitutes the back part
of the forge back; these parts are put together by screws c, as shown in the
various Figures, there being packing or luting at the joints in order to keep
the same water-tight. d is the induction pipe, and e is the eduction pipe,
which respectively lead from and to a tub or vessel containing water, which
is placed in any convenient situation in order that water may constantly flow
to and from the hollow forge back a, b, as is clearly shown in Figure 5. I
would here remark that the hollow forge back is to be set in like manner to
ordinary backs of forges, and in other respects the forge is constructed as
heretofore.
Having thus described the manner of applying my Invention, I will shortly
state the way in which it acts. The heat of the fire against the part a of the
back of the forge will quickly heat the water contained in the hollow forge
back, the consequence of which will be that the hotter particles will rise
upward and flow off by the pipe e, whilst a quantity of colder water will
constantly flow by the pipe d to make up for that which flows off by the
pipe e, and thus will a continued circulation or flow of water take place in the
hollow back of the forge, which, continually carrying off heat therefrom, will

page_text: prevent the forge back becoming heated to that extent to which it has hereto-
fore been liable. In conclusion I would wish it to be understood that I lay
no claim to any parts of the forge which are well known and in use. And I
do hereby declare that what I claim as my Invention of an improvement on
forges consists in producing a circulation of water within the forge back, as
above described.
In witness whereof, I, the said John West, have hereunto set my
hand and seal, this Second day of June, in the year of our Lord One
thousand eight hundred and thirty-five.
