TT
COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 26th September 1866, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED BRONZING
MACHINE," and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same, and have
made solemn Declaration that it has been communicated to me from abroad
by John Knox Lowe, of Cleveland, Ohio, United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification under my hand and seal fully
describes and ascertains the nature of the said Invention, and in what"

page_text: manner the same is to be performed in and by the following statement,
reference being had to the accompanying Drawings. forming part of this
Specification.
The said Invention relates to a machine for receiving the prepared sheet,
bronzing it, and discharging the same finished by one continuous automatic
operation, as herein-after described.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a top view of the machine; Figure 2 is a rear end view;
Figure 3 is a side view; and Figure 4 a front view of the same. Like letters
of reference refer to corresponding parts in the several Figures.
A is the framing of the machine which may be constructed of wood or other
suitable material. In this frame is arranged a system of rollers in connection
with a pair of bronzing cases in the order and manner as follows:-B, B', are
the cases above referred to, and which may be made of tin or any other
suitable material; these cases are so arranged in the frame as to permit of
their being taken out for the purpose of cleaning the rollers when surcharged
with bronze or coloring material. In the case B is a roller C, the shaft of
which D, as also the shafts of all the rollers, pass through the sides of the
framing, and in which they have their bearings. On the outer end of the
shafts D are the wheels E, E¹, Figure 2, E being a crank wheel; E¹, a gear
wheel, and by the means of which the machine is driven. The roller C is
less in diameter than the case, and the space thus between the two is filled
with fur F or any soft floculent material of a suitable nature. In this the fur
consists of a skin, and is secured to the face of the roller, so that the pile
reaches to and presses against the face of the case. The case B¹ also contains
a roller G, and which like that in B is less in its diameter than the case.
The space between these two is filled with fur or other suitable material like
the one above referred to, but in this case the direction of the pile is the
reverse of that in the one described; in this the case is lined with fur, the pile
facing the roller which here presents a smooth even surface to the lining.
H is a box or hopper, the bottom of which is perforated with fine holes to
answer the purpose of a sieve; one side of this hopper is connected to a shaft I
which permits of its being lifted upward by the arm J as it is operated by the
several points K, the purpose of which will be shown hereafter; L is a brace
for the supporting of the case in its proper position; M is a fur to be referred
to hereafter; N is a bar, to which is attached the apron 0; this apron consists
of a soft cotton cloth or fur, and reaches around the draw roller P which it
lightly touches. The rollers 1, 2, 3, and 4 are the feed rollers for the purpose

page_text: of conveying the sheet to the bronzers. Rollers 5 and 6, by the aid of the
Jarge one P, return the sheet after passing through the process of bronzing.
R, R', Figure 3, are endless belts or bands running between the rollers.
These bands are double, one lying directly upon the other, and between which
the work for bronzing is placed in order to hold it securely and smooth, and
guide it through the rollers.
The operation of the machine is as follows:-The bronzing powder, flock, or
coloring material on being thrown into the hopper H is then shaken through
to the fur roller by the arm and points above mentioned, the roller being fully
charged the sheet is then laid upon the bands at the front of the machine,
printed side upward. On turning the crank S the sheet passes under the
roller n and between the two belts, thence over the roller 3, under 4, to the
bronzing roller C, from whence it receives the bronze as it leaves the bronzer.
The surplus material is carefully brushed off by the wiper in the case B¹ as it
passes round the roller G within it out to Number 5, over which it passes to
the large draw roller P, when it is again wiped by the apron above
mentioned, and thereby all the remaining surplus powder is removed. As it
leaves this roller it passes around under 6, thence to the front between
rollers 1, 7; the bands here divide R, indicated by the dotted line, passes over
roller 1 to the top, on which was laid the sheet; the band R¹ passes over 7 to
and under 8 and 9, thence over 11 to 12, 13, to the place where the sheet
first entered. These bands are made of elastic tape, hence they are at all
times tight, and thereby hold the work smoothly and securely through the
machine. The brush M referred to is for the purpose of catching the waste
or floating powder, as it may drift back by the current of air consequent upon
the movement of the bronzing rollers, and is therefore kept from spreading
through the machine. Also it being more or less charged with the bronzing
material it assists in the process of bronzing, serving thus a two-fold purpose.
The bands may be adjusted to any sized sheet by moving them outward or
inward by the spools T, Figure 4, over which they run, and are guided and
kept in one uniform width.
It will be seen that by this arrangement of rollers and bronzers that the
work is fully completed at one operation, that it leaves the machine clean and
free of irregularity in the order of the work, and being automatic in the
execution thereof, it needs no special care on the part of the attending
operator beyond supplying it with the needful materials.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and shewn how the same may be advantageously
carried into practice, I claim,-

page_text: First, receiving the prepared sheet and bronzing it, cleaning and discharging
the same completed from the machine by one continuous automatic operation,
substantially as described.
Second, the bronzing case B, cleaning roller G, in combination with the
bronzing fur roller or its equivalent, for the purpose and substantially in
the manner set forth.
Third, the apron O, brush M, in combination with the sheet rollers
1, 2, 3, as arranged in the manner and for the purpose substantially as
described.
Fourth, the belts R and adjustable guides, as arranged and operating with
the rollers 11, 12, 13, in the manner and for the purpose specified.
In witness whereof, I, the said George Haseltine, have hereunto set my
hand and seal, this Twenty-sixth day of September, in the year of our
Lord One thousand eight hundred and sixty-six.
Witness,
