Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of the Patent Office, 166, Fleet Street, Gentleman,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Second day of November,
One thousand eight hundred and forty-eight, in the twelfth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Archibald Brooman, my exors, adññors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Richard
Archibald Brooman, my exors, adiñors, and assigns, and such others as I, the
said Richard Archibald Brooman, my exors, adñors, or assigns, should at
any time agree with, and no others, from time to time and at all times
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, the Invention of "CERTAIN IMPROVEMENTS IN THE MANUFACTURE
OF HINGES, AND THE MACHINERY OR APPARATUS USED THEREIN," being a communi-
cation from abroad; in which said Letters Patent is contained a proviso that I,
the said Richard Archibald Brooman, should cause a particular description of

page_text: the nature of the said Invention, and the manner in which the same is to be
performed, by an instrument in writing under my hand and seal, to be inrolled
in Her 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
Richard Archibald Brooman, hereby declare that the nature of the said
Invention, and in what manner the same is to be performed, are (according
as the same have been communicated to me) fully described and ascertained
in and by the present Specification thereof, reference being had to the
Drawings hereunto annexed (that is to say) :-
:-
Whereas, in the manufacture of hinges from folded plates of metal, the
different processes of folding, cutting out, and boring or punching the holes
for the screws and rivets have been hitherto accomplished more or less by
hand, and each of these processes has been performed as a distinct and
separate act. Now the improvements which constitute the present Invention
consist in effecting, by means of the machinery or apparatus represented in the
Drawings, and herein-after described, these operations at one and the same
time, or at least so nearly so that the intervals of time between them are so
small that they need not be taken practically into account.
Figures 1, 2, 3, and 4 represent different views of this machinery or ap-
paratus. Figure 1 is a general plan with some of the upper parts removed,
which are shewn in the other Figures. Figure 2 is a part side elevation.
Figures 3 and 4 are transverse elevations on the lines a, b, and c, d, of Figure 1.
A is the main driving shaft of the machine, which is put in motion by gearing
from the shaft B of some prime mover. A' and A2 are two shafts which are
connected with the shaft A by bevil gearing A³, A³, and carry two pairs of
cams I, I, and M, M, which give an alternating motion to the rods L, L, and
X, X, at every revolution made by the shafts A¹ and A. G and R are other
two cams, the former of which is affixed to a shaft G', which is driven by
intermediate gearing G2, G3, from the shaft A¹, and the latter to the shaft A.
The uses of these different cams will be afterwards explained. C, C, are two
bands or strips of metal out of which the hinges are to be formed; they are
held in their places by grips D, D, which are affixed to a sliding bar F, which
is acted upon by the cam G. As the bar F recedes from the centre of the
machine the grips D, D, glide easily over the strips of metal C, C, so as not
to alter their position, but the return movement of the bar F causes the grips,
by the action of the springs E, E, to catch the strips C, C, and make them

page_text: advance towards the centre of the machine. The instant this is accomplished
the cams I, I, cause the rods X, X, which carry at their inner ends cutters
N, N, and punches H, H, to press up against the strips of metal; the
cutters N, N, cut off two pieces, one from each strip, each of which pieces is
sufficient to form one half of a hinge. The punches H, H, at the same time
come upon the strips and cut out the slots or mortices in both halves of the
hinge (the punches on one side of the machine being exactly the reverse of
those on the other side, as will be understood from the next part of the
process). The two halves of the hinge cut off from the strips C, C, having
been previously punched out as described, occupy a position immediately in
front of the draw or compressing plates O, O; the cams M, M, make the rods
L, L, push the two halves of the hinge through the draw plates (in which state
they are in a V form, as represented in the plan Figure 1), till they interlock
the one into the other, the spaces in the one half being opposite to the solid
pieces of the other. When so interlocked, the cam G acting upon the lever
U causes the grip T to push a wire T3 down through a hole t into the inter-
locked halves of the hinge. The cam R then makes the matrix Q to advance
towards a reverse matrix P with the partially-formed hinge between them, by
which action the hinge is pressed into its complete form, and the wire T", which
forms the axis of the hinge, is cut off at the proper length. The counterpoise
upon the end of the lever U causes the grip T to slide upon the wire T', so
that it may take a fresh hold for the next repetition of the operation. The
catch s, which is affixed to the upright framing, holds the wire during the
sliding up of the grip T. The withdrawing of the matrix Q, Y, allows the
hinge to fall in nearly a complete state from the machine, all that remains to
be done being a little dressing with the file. The holes for the screws and
rivets may be punched out at the same time as the joints of the hinge itself
are being punched out by the punches H, HI,
And having now described the nature of the said Invention, and the manner
in which the same is to be performed, I declare that what is claimed under
the before in part recited Letters Patent is, the peculiar arrangement and
combination of means constituting the improved machinery or apparatus
herein-before described, whereby the different operations in the manufacture of
folded plate hinges are performed simultaneously, or as nearly so as may be.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-seventh day of April, in the
year of our Lord One thousand eight hundred and forty-nine.
R. A. (L.s.) BROOMAN.
