IMPROVEMENTS IN HINGES
Year: 1877

page_text: LETTERS PATENT to Adolph Felsenthal, of the Firm of A. and M. Felsenthal
and Company, of Bury Court, in the City of London, Merchant and Manu-
facturer, for the Invention of "IMPROVEMENTS IN HINGES."
PROVISIONAL SPECIFICATION left by the said Adolph Felsenthal at the
Office of the Commissioners of Patents on the 14th May 1877.
ADOLPH FELSENTHAL (of the Firm of A. and M. Felsenthal and Company), of
Bury Court, in the City of London, Merchant and Manufacturer.
"IMPROVEMENTS
IN HINGES."
My Invention relates more particularly to that description of hinges technically
known as "
stop hinges," which are used as attachments to doors, desks, cases,
boxes, tables, and other articles of furniture, also musical instruments and other
objects or articles, the opening action of which it is desired to limit in extent, so as
to stop when opened as far as to form a given angle with the plane of attachment.
The object of iny Invention is to make such hinges so that not only is the tendency
(in stop hinges of the ordinary construction) to permit the doors, leaves, flaps, or
lids, to which such hinges are attached, to exceed the desired extent of opening
effectually overcome, but I accomplish this also in such a manner as not to leave
any portion of the joint of the hinge projecting beyond the outside of the jointed
surfaces, which are thus caused to be perfectly "flush" or free from any obstruction
at the part where jointed. I accomplish this also without employing more metal
or necessitating more labour than is required in the ordinary construction of
hinge.
"
In the hinges, according to my Invention, each of the leaves or halves of the
hinge (which are counterparts of each other) are perfectly " flush or flat on the
upper surface (instead of having a series of articulated tubes as in ordinary "stop" and
other hinges), and the necessary thickening of the metal where the joint pin passes

lower surface of each of the leaves or halves of the hinge, so that on the two halves
being put together, with the joint pin passing through the same, the upper surface of
each of the leaves or halves of the hinge is exactly "flush," and at the same time
great power of resistance is given by this mode of construction, so as to form an
effectual "stop" to the opening of doors, leaves, flaps, or lids, to which such hinges,
according to my Invention are attached, beyond the desired extent.

the said Adolph Felsenthal in the Great Seal Patent Office on the 13th
November 1877.

My Invention relates more especially to that description of hinges known

or articles, the opening action of which it is desired to limit in extent so as to stop

stop hinges of the ordinary construction) to permit the doors, leaves, or flaps or lids
to which such hinges are attached to exceed the desired extent of opening effectually
overcome, but I accomplish this also in such a manner as not to leave any portion of
the hinge, when closed or open, projecting beyond the outside of the jointed surfaces,
which are thus caused to be perfectly "flush or free from any obstruction at the
part where jointed. I accomplish this also by employing less metal and with less
labour than is necessary in the ordinary construction of stop hinges.

"
In the hinges, according to my Invention, cach of the leaves or halves (which are
counterparts of each other) are perfectly "flush or flat on the upper surface (instead
of having a series of articulated tubes, as in ordinary stop hinges), and the necessary
thickening of the metal where the joint pin passes through the series of indentations
and projections of each of the leaves or halves of the hinge is given by forming a
boss," serving as a bearing surface, also underneath the lower surface of each of the
leaves or halves of the hinge, so that on the two halves being put together, with the
joint pin passing through the same, the upper surface of each of the leaves or halves
of the hinge is exactly "flush," and at the same time great power of resistance is
given by this mode of construction, so as to form an effectual stop to the opening of
doors, leaves, flaps, or lids (to which such hinges, according to my Invention, arc
attached) beyond the desired extent.
In the accompanying Sheet of Drawings, Figures 1 to 8 inclusive, I have illus-
trated the hinges according to my Invention as herein specified, the said Drawings
being self-explanatory. I wish it to be understood however that I do not confine
myself to the angle at which the hinges, according to my Invention, are caused to
stop, as this may be varied to suit the circumstances of application by giving the
corresponding formation necessitated to the herein-before described "boss" portion
of the said hinges, and which may be either cast, or they may be stamped out of
sheet metal.
Having thus particularly described and ascertained the nature of my said Inven-
tion and the manner in which the same is to be or may be performed, I claim as
my Invention to be secured by the herein-before in part recited Letters Patent, the

page_text: improvements in hinges, substantially as herein-before set forth and described, and
illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Adolph Felsenthal, have hereunto set my
hand and seal, this Thirteenth day of November, in the year of our Lord
One thousand eight hundred and seventy-seven.
