filed by the said William Robert Lake in the Great Seal Patent
Office on the 9th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, F, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of November, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Robert Lake, Her special licence
that I, the said William Robert Lake, my executors, administrators,
and assigns, or such others as I, the said William Robert Lake, my
executers, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times. thereafter during the
term 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 "AN IMPROVED
APPARATUS TO BE PLACED ON A SMITH'S FORGE TO ENSURE THE MORE EFFECTUAL
HEATING OF BARS OR RODS USED IN MAKING BOLTS, RIVERS, AND OTHER LIKE
ARTICLES," a communication to me from abroad by George Chapman
Bell, of Buffalo, New York, United States of America, Manufacturer,
upon the condition (amongst others) that I, the said William Robert
Lake, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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
immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification
―:
The said Invention relates to a simple and convenient apparatus which
may be adapted to any smith's forge or hearth, either fixed or portable,
but is chiefly designed to be used on small forges for making bolts,
rivets, and other like articles or pieces, to ensure a more effectual and
economical heating of the same.
The body of the said apparatus is an oblong hollow frame of cast iron,
and forms a water box or chest, whose hollow sides enclose an open
space. This frame is so placed upon the hearth as to surround the fire,
which burns in the said open space. The front side of the frame has any
desired number of holes, through which the ends of the bars or rods to 1
be heated are thrust into the fire.
When the said apparatus is to be used in forging bolts, rivets, and
similar articles of large or medium size, I make provision for the holes
by constructing the front part of the frame with tubes passing through
the same, the said tubes being surrounded by the water in the frame.
But for very short bolts or other articles I make through the said front
part of the frame a long aperture or slot, and fix therein a thin plate of
steel or other suitable metal, in which the holes for the admission of the
iron bars or rods are made.
I provide for the maintenance of a continuous stream of cold water
through the apparatus by a proper arrangement of pipes in connection
with a pump or other means for supplying the water to the same.

page_text: A, A, are standards or uprights, upon which the said apparatus is
supported, and which are erected and secured upon the blocks B, or upon
some other suitable foundation. a is the hollow frame or water box
surrounding the fire.
I prefer to construct the said frame in two parts, one part a¹ forming
the rear side and the two ends of the frame, and the other part a³
forming the front side of the said frame; this part a³ has the small tubes d,
through which the bars or rods are passed into the fire; the latter being
made in the usual manner upon the hearth or grate bars c. Making the
frame in two parts facilitates and cheapens its construction, and allows
the front part when worn out or injured to be readily removed and
replaced by a new piece. By thus inserting the iron bars or rods through
the holes in the frame, they are heated only at the part required, and
therefore the heating is accomplished more rapidly, and with a smaller
consumption of fuel than would otherwise be practicable. And if only
coke or anthracite coal is used, the fire will always to free from clinkers
and dirt, and the iron bars or rods will be clean when withdrawn from
the fire.
In the modification of my apparatus illustrated in Figures 5 and 6, ƒ is
the aforesaid thin plate with the series of holes for the admission of the
iron rods or bars. This thin plate permits the heating of short pieces or
articles more conveniently than when the holes are formed through the
cast-iron frame. The plate fis secured to the frame a by bolts or screws
at f, and when worn out may be readily replaced by a new plate. The
pipes for conducting the water into and through the hollow frame or
box a are most clearly shewn in Figure 1. The admission pipe g is
connected at one end of the hollow frame or box a to both the front and
back portions a¹, a³, of the same, and extends therefrom to the cistern or
reservoir, or or the pump or other supplying vessel or apparatus. The
exit or discharge pipe h is also connected to the two parts a¹, a³, of the
hollow frame at the opposite end of the same, and is arranged to conduct
the water away from both parts of the frame a, so that a continuous
stream or current of water is maintained all around and through the said
frame.

ash-pan, as shewn.
Having thus fully described the said Invention as communicated to me
by my foreign correspondent, and the manner of performing the same, I
wish it understood that I claim,-
First. A hollow frame or box constructed to be placed upon a smith's
forge or hearth so as to enclose or surround the fire thereof; and
provided with holes or apertures for the insertion of the rods or bars of
iron, and with appliances for maintaining a continuous stream of cold
water through it, as herein set forth.
Second. Constructing the said hollow frame, in two portions, as herein
set forth for the purpose specified.
Third. Constructing the said frame or one side or portion thereof with
a thin metal plate perforated with a series of holes as shewn in Figures 5
and 6 of the accompanying Drawing, for the purposes set forth.
In witness whereof, I, the said William Robert Lake, have here.
unto set my hand and seal, this Ninth day of May, in the of
year
our Lord One thousand eight hundred and seventy-two.
