AN IMPROVED METHOD OF OPENING AND CLOSING SASH WINDOWS OF ANY DESCRIPTION

I HORATIO WALTER IBBOTSON of 23, Change Alley Sheffield in the County of
York Gentleman do hereby declare the nature of my invention for "AN IMPROVED
METHOD OF OPENING AND CLOSING SASH WINDOWS OF ANY DESCRIPTION and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My Invention relates to and claims to be an improvement upon, the method
already adopted of opening and closing Sash Windows by means of toothed Racks,
and Cog wheels working into same, and which, as so already employed, as applied
to Railway or other Carriages, obtain therefor an equal parallel movement and
avoidance of the use of fence plates, and, as applied to house sash Windows, are so
as to dispense with the ropes attached to side weights working over pulleys.
My present object as applicable to sash windows, whether for Railway or other
vehicles, or for houses or other buildings, is to fix and arrange the Rack in a
simple way, without interfering with the side Window frames or side recesses, up
and down which the moveable frame works.
To effect this for Carriage Windows, I affix or attach the toothed Rack by
screws or otherwise to the beading of the moveable frame at one side, for, the
whole or nearly the whole length of such moveable frame, and such Rack is fixed
with the toothed part inwards, parallel to the Sash-Such Rack is then continued
for six or twelve inches below the Sash, and the Cog wheel to act upon the Rack,
works against same from the inside of the lower stationary framework (spaces or
recesses being left or made there for the purpose) and to the Axle of this wheel,
an outside Handle with Knob is attached, and by this means, the action is gained
direct by the hand.
For double Sash Windows for Houses or other Buildings, the Rack is (on opposite
sides) attached at the like side position, to the bottom of the Sashes respectively,
but such Racks are made considerably stronger (as may be required) than those for
Carriages, and work into holes or spaces bored or left underneath, of a sufficient
width to receive the same, the Rack, for the top sash, working behind the beading
of the lower Sash-Where only one Sash is used, one Rack only is required.
I usually make the Cog wheels of light construction, and for the outside handlo
or lever, in some cases I find it convenient to employ a common form of light
wheel handle, in which the handle is attached to the radius of the wheel.
To sustain the Windows and lessen the weight, where necessary or desirable,
I usually employ, according to weight of the Sashes (as already adopted) one or two
477

page_text: india rubber or spiral or other springs, working from the top in the side recesses
or grooves for such purpose, and I sometimes employ an additional Cog wheel
or wheels, to operate upon and assist the working of the Cog wheels already
mentioned.
To keep up the Sash or moveable frame, when fully open, or at any desired
distance, I usually employ a Check, to be worked by hand from the outside, to
operate, by means of a sliding bolt, either at or upon the principal Cog wheel or
wheels, or on a toothed or grooved outside wheel placed against the handle, but I
do not claim for any novelty in such checks, nor do I confine myself to the
employment of any form of Check which may be desirable for the purpose.
The accompanying Drawings illustrate some of the features of my Invention.
Figure 1. is a general front view of a Railway or other Carriage Window, with
the Rack fixed or attached to same.
Figure 2. is a like view, as applicable to double sash House Windows.
Figure 3. is a side view, shewing the action of the Cog wheel with Axle and
outside Handle.
Like letters of reference where such letters appear, indicate corresponding parts
in the Drawings.
In Figure 1, the Rack A which moves the Sash with the glass frame B, is fixed
or attached, by screws or otherwise, to the beading C at such side of the moveable
frame, extending up the whole or nearly the whole length of such frame, and such
Rack being fixed with the toothed part inwards, parallel to the Sash, the same
with such Sash or moveable frame, is worked up and down by means of the Cog
wheel D operating on such Rack.
. .The inside of the top portion of the lower stationary frame or framework, is
made or left with spaces or recesses to receive the parts (such inner working being
exposed to view on the Drawing) and a special inner space E is also made or left
underneath for the Rack to move into.
To the Axle of the Cog wheel, an outside Handle with Knob F is attached, to
be worked by the band, and by this means the action is gained direct.
In Figure 2. the Rack is attached to the Sash to a short extent, spaces on both
sides G being made or left to receive the full lengths of Rack, the Rack to the
lower Sash being fully down when such Sash is quite closed, and the Rack to the
top Sash being fully down when such Sash is quite open.
In Figure 3. the side working of the Cog wheel and Handle are illustrated, the
Cog wheel D. being worked by the Handle F.
The above contrivance is also specially applicable, as requiring slight alterations
only, to existing Railway or other Carriage Windows, or to House Sash Windows.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
For the opening and shutting of Railway or other Carriage Windows, or for
Sash Windows for Houses or other Buildings, a new method, as above described, of
affixing or attaching a toothed Rack, with the toothed part inwards parallel to the
Sash, and Cog-wheel below with appliances to work such Rack, whereby such
Rack and wheels can easily be fixed or adjusted, whether for new Windows, or for
those already in use.
