Islington, in the County of Middlesex, for the Invention of "CLOSEING
OF DOORS, WINDOWS, AND OTHER SUCH APPERTURES WITH A SPRING WHEN

NECESSARY TO CLOSE THEM BY SUCH MEANS."
Sealed the 17th December 1867, and dated the 19th. Juné: 1867.
PROVISIONAL SPECIFICATION left by the said John Coppard at the
Office of the Commissioners of Patents, with his Petition, on the 19th
June 1867.
I; JOHN COPPARD, of 42, Park Street, Upper Street, Islington; in the
County of Middlesex, do hereby declare the nature of the said Invention
for "CLOSEING OF DOORS, WINDOWS, AND OTHER SUCH APPERTURES WITH A SPRING.
WHEN NECESSARY TO CLOSE THEM BY SUCH MEANS," to be as follows:-
This Invention consists in adapting a ring made of india-rubber or other
elastic substance to substitute the ordinary springs used for the purposes
before mentioned, which said rings: may be round, square, or flat, I prefer
them being flat.
The following is an example of the means by which this Invention may
be carried into practicle effect:-First, as regards the ring before referd to,
it may be of any of the before mentioned form's, of any size, length, or sub-
stance, to which I attach two pieces of brass or other metal or any other
suitable substance made so as to receive the elastic ring. I then passon
२

page_text: rivit or screw through such pieces of metal, thereby holding the elastic ring
secure, or it may be done by forming an hook thus S or other suitable
means, such pieces of metal or S hook to be secured to the doors, posts, &c.
by means of ordinary studs, hooks, or screw hooks, and when necessary to use
such spring on the inside of door, &c. an iron bracket may be used, so that
this Invention may be known (in addition to the differance of construction
of others) I propose nameing it the excelsior door spring.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Coppard in the Great Seal Patent Office on the 18th
December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
COPPARD, of 42, Park Street, Upper Street, Islington, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Coppard, Her special licence that I, the said John Coppard, my exe-
cutors, administrators, and assigns, or such others as I, the said John
Coppard, 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. "CLOSING OF DOORS,
WINDOWS, AND OTHER SUCH APERTURES WITH A SPRING WHEN NECESSARY TO CLOSE
THEM BY SUCH MEANS," upon the condition (amongst others) that I, the said
John Coppard, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain' the nature of the said Invention, 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 Coppard,: do hereby. declare
the nature of the said Invention, and in what manner. the same is to be
performed, to be particularly described and ascertained in and by the
following statement, that is to say :-

page_text: This Invention consists in adapting a ring made of india-rubber or other
elastic substance to substitute the ordinary springs used for the purposes
before mentioned, which said rings may be either round, square, or flat, I
prefer them being flat.

The following is an example of the means by which this Invention may be
carried into practical effect:-First, as. regards the rings before referred to
they may be of any of the before-mentioned forms, and of any size, length,
or elastic substance, to which I attach two pieces of brass or any other metal
or other suitable substance made so as to receive the elastic rings, I then
pass a rivet or screw through such pieces of metal, thereby holding the ring
securely, or it may be done by forming a hook thus S or by other suitable
means, such pieces of metal or S hooks to be secured to the door posts and
other parts by ordinary studs, screw hooks, or screws, and when necessary to
use such spring on the inside of the door an iron bracket may be used.
This Invention to be known apart from its difference of construction to all
other springs as the excelsior door spring and closer..
And in order to explain my said Invention as completely as possible, I now
proceed to describe the best means I am acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheet of
Drawings accompanying these Presents, and to the numeral figures and
letters of reference marked thereon, as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 represents a side elevation of a spring constructed according to
my said Invention, and adapted for closing doors and other hinged articles of
a similar nature; Figure 2 a top plan view of Figure 1; Figure 3a detached
portion herein-after more particularly described and referred to.
At each of the foregoing Figures I employ similar letters of reference to
denote corresponding parts, in so far as such parts appear or can be seen at
each of such said Figures respectively. A marks a flat ring of vulcanized india-
rubber or other suitable elastic substance; B, B, pieces of matal through
each of which a pin, rivet, or screw a passes; b, a loose collar of metal or other
suitable substance encircling the piece a, the piece b being employed to
prevent friction or abrasion of those parts of the ring A which pass over the
piece b; C, C, are rings of india-rubber or other suitable substances
employed to keep the ring A flat and straight, I propose, if desirable, to make
those parts of the ring A which pass over the pieces-b, b, rigid and stronger
than the other parts of the said ring, which may be effected by inserting
pieces of woven material between the thicknesses of india-rubber, say from

page_text: 1 to 2 during its manufacture, and when this is the icase the loose pieces'b, b,
may
be dispensed with, and the pin, rivet; or screw a tonly: be employed;
iD is a screw ring, and E a screw, hook for connecting the spring to a door
by one end and to the door post by the other end, by screwing them into the
woodwork. The hook E allows the spring to be detached when necessary.
Having now fully described and set forth the nature and object of my
said Invention, together with the best means I am acquainted with. for
carrying the same into i practical effect, I. hereby declare my Invention to
::consist in and I claim. the arrangement and combination of the parts above
described with reference to the. accompanying Drawing, for the purpose of
closing doors, fan lights, and other similar articles to which springs have
:heretofore been employed to close thein. *
In witness whereof, I, the said John Coppard, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-seven.
