Year: 1875

page_text: LETTERS PATENT to George Beaumont, of the City of Manchester,
Engineer, for the Invention of "IMPROVEMENTS IN THE FITTINGS OF
WINDOW SASHES FOR RAILWAY AND OTHER CARRIAGES, AND FOR OTHER
PURPOSES."
Sealed the 31st August 1875, and dated the 5th March 1875..
PROVISIONAL SPECIFICATION left by the said George Beaumont at
the Office of the Commissioners of Patents, with his Petition, on
the 5th March 1875.
I, GEORGE BEAUMONT, of the City of Manchester, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE FITTINGS OF WINDOW SASHES FOR RAILWAY AND OTHER CARRIAGES, AND FOR
OTHER PURPOSES," to be as follows:-
The window sash is free to move up or down in the frame of the door.
A toothed rack is attached to the door frame of a railway carriage,
coach, cabriolet, or other vehicle, house, or other window frames, or
door frames. Into this rack works a spring catch or pin attached to the
sash.

page_text: As applied to railway and other carriages, in order to keep this
catch to its work I attach a spring to the frame, and the sash is thrown
over the fence plate when up by an outward pressure of the elbow
against the window, which pressure overcomes the resistance of another
spring on the opposite side of the frame, this last-mentioned spring
being employed to throw the sash over the fence plate before lowering
the window. The spring catch or pin is released from the rack by
means of a ring or other contrivance attached to the sash, and the sash
can be raised or lowered by pulling the ring inwards. The spring at
the back of the sash forces the pin into the rack and allows the sash to
be left partly open or just so much as may be required. By this means
the usual counterweights are dispensed with, and the window sash can
be raised or lowered with one hand.
In applying my Invention to house and other windows the position of
the lifting rings and of the springs is reversed, or otherwise altered to
suit the different conditions required.
о
Another part of my Invention consists in making the racks for
window sashes of buffalo hide, vulcanite, or other similar substance to
reduce the noise in opening or closing the window.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said George Beaumont in the Great Seal Patent Office
on the 4th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BEAUMONT, of the City of Manchester, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of March, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Beaumont, Her special
licence that I, the said George Beaumont, my executors, administrators,
and assigns, or such others as I, the said George Beaumont, 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,

page_text: and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN THE FITTINGS OF WINDOW SASHES FOR RAILWAY AND OTHER CARRIAGES,
AND FOR OTHER PURPOSES," upon the condition (amongst others) that I,
the said George Beaumont, 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 George Beaumont, 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 (that is to say) :-
The window sash is free to move up or down in the frame of the door.
A toothed rack is attached to the door frame of a railway carriage,
coach, cabriolet, or other vehicle, house, or other window frames, or door
frames. Into this rack works a spring catch or pin attached to the
sash.
As applied to railway and other carriages, in order to keep this
catch to its work I attach a spring to the frame, and the sash is thrown
over the fence plate when up by an outward pressure of the elbow
against the window, which pressure overcomes the resistance of another
spring on the opposite side of the frame, this last-mentioned spring
being employed to throw the sash over the fence plate before lowering
the window. The spring catch or pin is released from the rack by
means of a ring or other contrivance attached to the sash, and the sash
can be raised or lowered by pulling the ring inwards. The spring at
the back of the sash forces the pin into the rack and allows the sash
to be left partially open, or just so much as may be required. By this
means the usual counterweights are dispensed with, and the window sash
can be raised or lowered with one hand.
In applying my Invention to house and other windows the position of
the lifting rings and of the springs is reversed, or otherwise altered to
suit the different conditions required.

page_text: Another part of my Invention consists in making the racks for
window sashes of buffalo hide, wood, paper, vulcanite, or other
similar substance, to reduce the noise in opening or closing the
window.
And in order that my Invention may be fully understood and
readily carried into operation, I will proceed to describe the accom-
panying Drawing, in which Fig. 1 is a front view, and Fig. 2 a
transverse section of the door of a railway carriage to which my im-
provements are applied.
a is the frame of the carriage door, and 6 the sash or window which
is moved up or down in the lower part of the door; c is a toothed rack
fixed to one side of the door frame, and this rack is made of buffalo
hide, wood, paper, vulcanite, or other similar material to reduce the
noise in opening or closing the window sash, or it may be made of
metal. To the window frame is fixed the plate d, shewn detached in
Figs. 3 and 4, and the spring catch e taking into the teeth of the rack c
is secured to the back of the plate d; the catch e is held in gear with
the rack by the spring which is secured to the sash and acts
against the door frame; there is a second spring 7 secured to the door
frame and acting on the lower part of the sash; the object of which is to
throw the sash over the ordinary fence 6' before lowering the window.
To the upper part of the sash is also secured the ring h, which is placed
on the inside of the carriage, and the knob i which comes outside to
enable the sash to be raised or lowered from the platform.
The mode of operation is as follows, and the Drawing, Fig. 2, shews
the parts in the positions they occupy when the sash is partly down :-
When the position of the sash has to be changed the passenger takes
hold of the ring & and pulls the upper part of the sash towards him to
draw the catch e out of the teeth of the rack c, the sash can then be
raised or lowered to the required extent, and as soon as the ring & is
released the spring again presses the catch e into gear with the rack to
hold the sash firm. When the sash has been raised to close the window
entirely, the passenger by pressing the lower part of the sash with his
elbow overcomes the resistance of the spring 9 and brings the angle
rib ² over the ordinary fence b¹, thereby securely closing the window.
In order to re-open the window the passenger must raise the sash
slightly to lift the angle rib b² over the fence b', the spring then forces

page_text: the lower end of the sash clear of the fence, and the sash can then be
lowered to the required extent. By means of this Invention the window
sashes can be opened or closed with great facility and with one hand,
and the ordinary counterweights are dispensed with.
Figs. 5 and 6 represent a modification of my Invention. In this case
instead of the rack c above described, I use a strip of vulcanized india-
rubber or other suitable material c¹; this strip is provided with
holes into which the stud e¹ enters, and this stud is secured to a
spring fixed to the plate d' which is screwed to the upper end of the
sash.
In applying my Invention to house and other windows, the position
of the lifting rings and of the springs is reversed or otherwise altered to
suit the different conditions required.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim,―
First. The general combination and arrangement of the fittings of
window sashes for railway carriages and for other purposes, whereby
the sashes can be opened and closed with facility, as shewn and
described.
And, Secondly. Making the racks for window sashes of buffalo hide,
vulcanite, vulcanized india-rubber, wood, paper, or other similar sub-
stance, as shewn and described..
In witness whereof, I, the said Gearge Beaumont, have hereto set
my hand and seal, this Second day of September, One thousand
eight hundred and seventy-five.
