Year: 1858

page_text: LETTERS PATENT to George William Bales, of Ipswich, in the County of
Suffolk, Gun Maker, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR RETAINING DOORS, SASHES, OR FRAMES WHEN SHUT OR CLOSED."
Sealed the 18th March 1859, and dated the 1st December 1858.
PROVISIONAL SPECIFICATION left by the said George William Bales
at the Office of the Commissioners of Patents, with his Petition, on
the 1st December 1858.
I, GEORGE WILLIAM BALES, of Ipswich, in the County of Suffolk, Gun
Maker, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN APPARATUS FOR RETAINING DOORS, SASHES, OR FRAMES WHEN SHUT OR CLOSED,"
to be as follows:-
This Invention has for its object improvements in apparatus for retaining
doors, sashes, or frames when shut or closed. For these purposes a plate is
fixed to the edge of a door, sash, or frame, or to the post or frame against or in
which the same is shut. or closed. Through this plate a hole is formed to
admit of a portion of a sphere protruding through. The sphere or such
like bolt is contained within a tube or chamber at the back of the plate,
which chamber is closed at its end, and between the end of the chamber and
the back of the sphere à spring is applied which constantly presses the sphere
outwards. On the door, sash, or frame, or on the post or frame against which
the same closes, is another plate having a hole to receive the protruding part of

page_text: the sphere. By this arrangement the sphere has not only the capability of
rotating, but also of receding, by which the door, sash, or other frame may be,
opened and closed simply by pressure, and without otherwise acting on the
sphere, which acts as the bolt or retaining instrument. Provision may be
made for fastening the sphere or bolt when shut, and thus prevent it acting till
unfastened.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George William Bales in the Great Seal Patent Office on
the 1st June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WILLIAM BALES, of Ipswich, in the County of Suffolk, Gun Maker, send
greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George William Bales, Her special licence that I, the said George
William Bales, my executors, administrators, and assigns, or such others as
I, the said George William Bales, 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 APPARATUS FOR RETAINING DOORS, SASHES, OR FRAMES
WHEN SHUT OR CLOSED," upon the condition (amongst others) that I, the said
George William Bales, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 George William Bales, 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 thereof, that is to say:-
.. This Invention has for its object improvements in apparatus for retaining

page_text: doors, sashes, or frames when shut or closed. For these purposes a plate is
fixed to the edge of a door, sash, or frame, or to the post or frame against or
in which the same is shut or closed. Through this plate a hole is formed to
admit of a portion of a sphere protruding through. The sphere or such like
bolt is contained within a tube or chamber at the back of the plate, which
chamber is closed at its end, and between the end of the chamber and the back
of the sphere a spring is applied, which constantly presses the sphere outwards.
On the door, sash, or frame, or on the post or frame against which the same
closes, is another plate having a hole to receive the protruding part of the
sphere. By this arrangement the sphere has not only the capability of rotating,
but also of receding, by which the door, sash, or other frame may be opened and
closed simply by pressure, and without otherwise acting on the sphere, which
acts as the bolt or retaining instrument. Provision may be made for fastening
the sphere or bolt when shut, and thus prevent it acting till unfastened.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto

page_text: desired, the sphere may be prevented from receding into the tube c, and so
fasten the door, sash, or frame, and prevent them being opened or closed by
pressure, by screwing the screw finto the groove e¹ of the circular plate e.
Fig. 3 shews a section and Fig. 4 an exterior view of another apparatus for
retaining doors, sashes, or frames when shut or closed. In this apparatus the
-plate e and screw fare dispensed. with.
In witness whereof, I, the said George William Bales, have hereunto set
my hand and seal, this Thirtieth day of May, in the year of our
Lord One thousand eight hundred and fifty-nine.
G. W. BALES. (L.S.)
