page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JABEZ
CARTER HORNBLOWER, of John's Row, City Road, in the Parish of Saint Luke,
in the County of Middlesex, Engineer, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fourth day of February, in the fortieth year of His reign,
give and grant unto me, the said Jabez Carter Hornblower, His especial
licence that I, the said Jabez Carter Hornblower, during the term of years
therein mentioned, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "A NEW MACHINE FOR AND METHOD OF GLAZING CALLICOS, COTTONS, MUSLINS,
&c. ;" in which said Letters Patent there is contained a proviso, obliging me, the
said Jabez Carter Hornblower, 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, relation being thereunto
had, may more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Jabez Carter Hornblower, do hereby declare that my said Invention is described
in the annexed Drawings, and the following description thereof (that is to
say :)-

page_text: My method of glazing the articles specified in the Patent granted for this
Invention is by passing the pieces under the stones the whole width of the
piece at once, and is effected by the following means:-The surface on which
the piece is laid, and which is intended to support it under the pressure neces-
sary to produce the effect, is made to revolve continually from one end of the
piece to the other, and is as perfect a cylinder as the application of judgment
and workmanship can make it, the length of it to be fully equal to the width
of the piece intended to undergo the operation. Over this cylinder is placed a
series of flint stones, having a proper face, which are pressed with a weight
corresponding to the texture of the article to be glazed, and have the property
of being raised off and let down with the greatest facility to the distance of
about half an inch, just so as to allow room for the person who tends the
machine to let the piece pass under. These stones have a continuance of
connection, either by being mitred, or suffering the end of one to pass
by the end of the other, so as to leave no interstice in the direction of the
circumference of the cylinder. The cylinder has its outer surface of hard wood,
such as hornbeam or beech, cut into segments and glued together on the
surface of an iron cylinder, mounted on a proper arbor; these segments are
secured there by a flanch at each end of the cylinder, through which are
inserted six or eight long bolts within the cylinder, both ends of which are
screwed, so that we may bring the flanches nearer together as the segments
shrink by drying or using.
Note. The cylinder may be of leather also. The piece having been pre-
viously waxed, is to have one end just laid under the stones, the stones then let
down upon it, and the cylinder put in motion at the rate of about a foot and a
half in a second, and the piece will be glazed in about two minutes, or it may be
done in one minute by giving a greater velocity to the cylinder. To describe
the particulars of this machine, Fig. 3 is a section of the frame of it, by
which you get a view of the end of the cylinder and one stone, together with
the mode of applying the weight upon it. The stone is confined in a pair of
strong chaps, in much the same manner as the flint in a gun lock, being first
set in lead, figured as near as possible to the form of the stone, and then
screwed up by the nut on the fore end of the bar. It then becomes a part of
the machine, which, for distinction sake, we may call a cock, as bearing same
resemblance to that part of a fire-lock. The other end of this bar has a
screw on it, by which means it is set forward, stone and all, or let backward, in
the following manner, see Fig. 4, which is the Drawing of the cock and stone,
and its manner of fixing to the machine on a scale of six inches to a foot.
X, X, is a section of the bars exhibited at e, e, in Fig. 3, which bars form a

page_text: groove for the support of the tail of the cocks, at the same time admitting
the cocks to be brought near to each other or further from each other,
and to be fastened in any point or position between these bars, where they have
also room to move upwards or downwards by the following means:-Figure 5
is a section of this part of the apparatus on a full scale. X, X, are the bars:
Y, Y, is a sort of band or box, which is made just to slile over these bars, and
having a hole on each side of it, before and behind, to admit the tail of the
cock, which is screwed for the length of five or six inches, in order to receive
two nuts, see n, n, Fig. 4, for the purpose of adjusting the cock and fixing it
when it is so adjusted, as may be seen in Fig. 1. This box has likewise two
the other to press against
thumb screws, one to press on the upper bar and
it
the lower bar so that when the tail of the cock is properly elevated or depressed
may be retained there. This mode of adjustment applies to all the cocks in
the bars, and these bars are made to meet together at each end, where they
terminate in a pivot, whereby the cocks are capable of any degree of elevation.
Fig. 4 shews the mode whereby these cocks are connected to the weight by
which the stones have their pressure. D is a perpendicular bar, the lower
end of which is inserted to the head of the cock, and the end is hollowed a
little, so as to saddle the part of the cock, whercon it is seated; and in order
that the cocks may rise with the utmost freedom, and fall in the most perfect
coincidence, with the faces of the stones to the surface of the cylinder, they
are connected to this perpendicular bar (which may be termed the pressing bar)
by a strap of iron, going on the round part of the cock bar between the chaps
quite easy, and from thence reaching upward along the pressing bar, where it
is secured by a small band, clasping them both together,
means of the screw
H. A, A, the chaps; B, the stone; C, the small band; D, the pressing bar;
F, the iron strap; E, the bar of the cock; G, G, the band or box on the
double bar. Thus I have described the most particular and intricate part of
the machine; what remains will be understood by referring to the different
Drawings, scarce yet mentioned, particularly Fig. 3, which is a section of the
machine, exhibiting at one view all the principal parts. A, one side of the frame,
on which is placed the cylinder B; and upon the cylinder comes the stone a in
the cock c, which is inserted between the bars 1, 1, having a motion on the piviot
working in the bracket b, b. d, the pressing bar, connected with the lever f,f,
carrying a weight w, of about one hundred pounds, near its extremity. This
weight must admit of being shifted to any part of the lever. This lever and
all the levers are raised at the same instant by means of a bar passing under
them, as is seen at x, Fig. 2, which being connected with the crank by the
rolls n, n, as in Fig. 3, from whence a rod and chain extends to the roller
دل

page_text: which is acted upon by the wheel h, having a rope laid on its circumference, or
by a simple lever, or any way more eligible to the person chusing to apply it.
I shews a section of the cap of the frame, which has a slit in a vertical direc-
tion, in manner of a lathe; in this slit are fixed a sort of poppets, which are
admitted to come to and from each other, and may be fastened by the key or
wedge i, so as to range the levers, weights, and pressing bars in a correspon-
dence with the cocks and stones. 7 shews the poppet; m, shews the manner of
connecting the lever to the poppet, that is, by a staple fixed in the lever, having
the ends thereof screwed, and furnished with nuts and washers for its adjust-
ment. Fig. 1 is a plan or horizontal section at the height of the cocks, and
A is the cylinder; D, D, the posts of the frame; B, B, the arbor of the cylin-
der; h, the double bar, wherein the cocks t, t, t, are arranged; b, b, the brackets
in which the double bar has its motion. Fig. 2 is a front elevation of the
machine. A, the cylinder; D, D, the posts or uprights of the frame; a, a, a, a, the
stones; fff, the pressing bars; 1,1,1, the ends of the levers; w, w, w, the
weights; a, the bar; which passes under the lever connected with the rods n, n,
with the roller g, by which the levers and weights are raised and let down. These
three Drawings are by a scale of one foot to an inch; Fig. 4, by a scale of six
inches to one foot; and Fig. 5 is a Drawing on a full scale. For waxing the
picces, they may be done by hand, or by the help of a machine. One of the
machines use for that purpose is on a method similar to the glazing machine,
i. c., by passing the pieces under the wax, by means of a cylinder of about three
feet diameter, with a piece or pieces of wax laid on the upper side of the
cylinder, and loaded with weight sufficient to press the wax down on the piece.
The weights, wax, and all are lifted up while the end of the piece is laid on
the cylinder and then let down again; then a roller being laid on the cylinder
just behind the wax, and the cylinder put in motion; the piece gets between
the cylinder and the roller, and is then drawn under the wax. The other
method is by passing the piece over a plank by means of a pair of rollers on each
side, the one to draw the piece along crosswise of the plank, which is about
six or eight inches wide; the other to hold back a little, whereby the piece is
kept tight and smooth, during which time a piece of wax is made to move back-
wards and forwards across the piece by means of a crank, until the whole piece
has moved along and the waxing is done.
In witness whereof, I, the said Jabez Carter Hornblower, have hereunto
set my hand and seal, this Third day of March, in the year of our
Lord One thousand eight hundred.
J. C. HORNBLOWER. (L.S.)
