Im- PROVEMENTS IN CONSTRUCTING AND FITTING BRACKETS FOR SHOP WINDOWS AND ARGEN Dune
Year: 1870

page_text: LETTERS PATENT to John Richard Cadman, of the Firm of John
Drew and Company, of Christopher Street, Hatton Garden, in the
County of Middlesex, Cabinet Joiners, for the Invention of “Im-
PROVEMENTS IN CONSTRUCTING AND FITTING BRACKETS FOR SHOP WINDOWS AND
ARGEN
Dune"
PROVISIONAL SPECIFICATION left by the said John Richard Cadman
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd April 1870.
I, JOHN RICHARD CADMAN, of the Firm of John Drew and Company,
of Christopher Street, Hatton Garden, in the County of Middlesex,
Cabinet Joiners, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CONSTRUCTING AND FITTING BRACKETS FOR SHOP WINDOWS AND
OTHER PURPOSES," to be as follows:-
The brackets employed in shop windows, in show cases, and in some
other places to support shelves or slabs of glass or other material have
hitherto been usually secured to metal bars by means of SCREW, the

page_text: consequence being that as the weight placed upon the brackets had to
be to a great extent borne by the screws, the connection was weak,
besides, considerable time was occupied in screwing the brackets to the
bars, and in unscrewing when it was desired to remove them or to alter
their position.
Now by means of my Invention all source of weakness is avoided and
the brackets can be fitted to the bars, be removed therefrom, and their
position be altered as desired with great facility.
My Invention consists in forming near that end of the bracket which
has to be fitted to the bar a vertical aperture of circular, square, or other
suitable form, and in carrying or extending this aperture out at the end
of the bracket by means of a slot or opening narrower than the said
aperture. Also in forming the bar to which the bracket is to be fitted
of a form the section of which corresponds with the said aperture, so
that the bracket can be moved up and down thereon, and in cutting
away at a point near the top or at any other convenient part of the bar
sufficient of the bar to allow the slot or extension of the aperture of the
bracket to be passed over it and the bracket thus slipped upon the bar.
I also form in the bar a scries of holes or notches, into one or other of
which a pin fitted within the aperture of the bracket takes so as to hold
the bracket in place, the bracket being allowed sufficient play on the
bar to enable the pin to pass the holes or notches when the outer end of
the bracket is slightly raised.
By constructing the brackets and bars as above explained the
brackets have simply to be slipped upon their bars and moved up or
down thereon into the required position, in which they are retained by
the aid of the pins and holes, the weight is not, however, thrown upon
the pins but is borne by the end of the bracket pressing against the
bar. The pin holes also serve as gauge holes to facilitate the proper
placing of the different brackets relatively to cach other.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Richard Cadman in the Great Seal Patent
Office on the 29th September 1870.

Joiners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Richard Cadman, Her special licence
that I, the said John Richard Cadman, my executors, adminis-
trators, and assigns, or such others as I, the said John Richard Cad-
man, my executors, 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
"IMPROVEMENTS IN CONSTRUCTING AND FITTING BRACKETS FOR SHOP WINDOWS AND
OTHER PURPOSES," upon the condition (amongst others) that I, the said
John Richard Cadman, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven
tion, 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.
NOW KNOW YE, that I, the said John Richard Cadman, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the accom-
panying Drawings, that is to say :—
The brackets employed in shop windows, in show cases, and in some
other places to support shelves or slabs of glass or other material have
hitherto been usually secured to metal bars by means of screws, the
consequence being that as the weight placed upon the brackets had to
be to a great extent borne by the screws the connection was weak;
besides, considerable time was occupied in screwing the brackets to the
|bars, and in unscrewing when it was desired to remove them or to alter
their position.

page_text: Now by means of my Invention all source of weakness is avoided, and
the brackets can be fitted to the bars, be removed therefrom, and their
position be altered as desired with great facility.
My Invention consists in forming near that end of the bracket which
has to be fitted to the bar a vertical aperture of circular, square, or other
suitable form, and in carrying or extending this aperture out at the end
of the bracket by means of a slot or opening narrower than the said
aperture.
Also in forming the bar to which the bracket is to be fitted of a form
the section of which corresponds with the said aperture, so that the
bracket can be moved up and down thereon, and in cutting away at a
point near the top or at any other convenient part of the bar sufficient
of the bar to allow the slot or extension of the aperture of the bracket
to be passed over it, and the bracket thus slipped upon the bar. I also
form in the bar a series of holes or notches, into one or other of which
a pin fitted within the aperture of the bracket takes, so as to hold the
bracket in place, the bracket being allowed sufficient play on the bar to
enable the pin to pass the holes or notches when the outer end of the
bracket is slightly raised.
By constructing the brackets and bars as above explained the brackets
have simply to be slipped upon their bars and moved up or down thereon
into the required position, in which they will be retained by the aid of
the pins and holes; the weight is not, however, thrown upon the pins,
but is borne by the end of the bracket pressing against the bar. The
pin holes also serve as gauge holes to facilitate the proper placing of the
different brackets relatively to each other.
The manner in which my Invention is carried into effect is represented
in the accompanying Drawings.
Figure 1 is a perspective view, and Figure 2 a plan of a bracket and
bracket bar; Figure 3 is an elevation of the bar alone.
A is the bracket; it is formed at that end which is fitted to the bar
with a vertical aperture B; this aperture is carried out at the end of the
bracket in the form of a slot or opening C narrower than the said
aperture. D is the bar, the section of which corresponds with the
aperture B. Part of the bar D is cut away, as shown at E, so as to allow
the slot C to be passed over it, and the bracket thus slipped upon the

page_text: bar. F, F, are a series of notches in the bar D, and G is a pin fitted
within the aperture B of the bracket. It will thus be seen that by
simply slipping the bracket upon the bar at the point E, sliding it down
to the required position, and allowing the pin G to take into one of the
notches F the bracket will be securely held. In moving the bracket up
or down upon the bar the outer end of the bracket should be kept slightly
raised so as to permit the pin G to run clear of the notches.
And having now described the nature of my said Invention, and
in what manner the same is to be performed, I declare that I claim,
constructing and fitting brackets for shop windows and other purposes,
substantially as herein-before described and represented in the accompany-
ing Drawings.
In witness whereof, I, the said John Richard Cadman, have here-
unto set my hand and seal, this Twenty-eighth day of September,
One thousand eight hundred and seventy.
