PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Operating and Fastening Sliding
Windows, Shutters, or Doors.
I GEORGE JONES Mechanist 17 Upper Phillimore Place High Street Kensington
London W. do hereby declare the nature of this invention to be as follows:-
In the case of railway & other carriage windows I cause them to open & shut by
opening or closing the carriage door or the pressing of a push button & in the case of
other sliding windows shutters or doors 1 cause them to shut or open by the pressure
of a button only or as aforesaid.
The combined mechanism consists of springs rack & pinion counterbalance
weights locks detents or catches, levers, palleys bands or chains according to the
dimensions weight & position of the doors windows or shutters to be operated upon.
Further details of the combined mechanism in this application for a patent for
automatically closeing or opening sliding windows, shutters, or doors.
I make a groove in the frames or caseings for such windows, shutters, or doors to
which this mechanism is applied and on such windows shutters or doors I fix a
rack running from bottom to top or from side to side as the case may require
and between the inner and outer caseings I fix in suitable bearings a roller
(either solid or hollow) with cog or spur wheels on each end that fit and couple
with the cogs on the rack before named. I also fix on the ends or inside the
roller coiled springs to cause the roller to revolve in its bearings and I fix a
ratchet wheel also on the roiler and in the inside of the caseing I fix in a suitable
position a catch or detent (that has a spring at its back) which catch or detent
couples with the ratchet wheel on the roller.
To fix this part of the combination for use I revolve the roller in its bearings
against the pressure of the aforesaid springs on the ends until the tension on the
springs is sufficent to overcome the weight and friction of the windows, shutters
or doors the catch or detent then holds them in position-in order to release and
allow the windows, shutters or doors to slide I press a push button having a spring
on its back that is fixed in a convenient place to come in contact with the catch or
detent and lift it off the ratchet wheel and allow the roller to revolve and cause the
windows, shutters, or doors to slide.
I also make a special lock for this combination which I fix in a suitable place to
also operate on the catch or detent which lock contains a bar or bolt that projects
beyond its caseing at each end and on the back end it is elongated as required
when this lock is placed on a door (such as a railway carriage or other carriage
door or any door to which this mechanism is in connexion) and operated upon
with a key or handle the projecting bar at one end locks or unlocks the door
and the projecting bar at the other end comes in contact with the catch or detent
and also allows the roller to revolve and the windows shutters or doors to slide
in the grooves.
I also use in this combination as a factor of safety balance weights and cross levers
fixed somewhat in the following manner.
I make fast in a suitable place the lower parts of one or more cross levers the
upper parts of which I secure to the window shutter or door that may be required to

page_text: slide. I connect the cross levers by bands, chains, or some such like articles after
passing them over pulleys fixed in the framework to balance weights placed in suitable
positions.

Improvements in Apparatus for Operating and Fastening Sliding
Windows, Shutters, or Doors.
I GEORGE JONES 17 Upper Phillimore Place High Street Kensington Mechanist
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
In the case of railway & other carriage windows-I cause them to open or shut by
opening or closing the carriage door or the pressing of a push button & in the case of
other sliding windows shutters or doors, I cause them to shut or open by the pressure
of a button only or as aforesaid.
The combined mechanism consists of springs, rack & pinion counterbalance weights
locks detents or catches levers pulleys bands or chains according to demensions
weight & position of the doors windows or shutters to be operated upon in the
following manner, I make a groove in the frame or casing for such windows
shutters or doors to which this mechanism is applied & on such windows shutters or
doors 1 fix a rack running from bottom to top or from side to side as the case may
require & between the inner & outer casings. I fix in suitable bearings a roller
(either solid or hollow) with a cog or spur wheel on each end that fit & couple with
the cogs on the rack before named. I also fix on the ends or inside this roller coiled
springs to cause the roller to revolve in its bearings & I fix a ratchet wheel also on
the roller and in the inside of the casing I fix in a suitable position a catch or detent
(that has a spring at its back) which catch or detent couples with the ratchet wheel
on the roller. To fix this part of the combination for use I revolve the roller in its
bearings against the pressure of the aforesaid springs until the tension on the springs
is sufficient to overcome the weight & friction of the windows shutters or doors the
catch or detent then holds them in position. In order to release & allow the
windows shutters or doors to slide, 1 press a push button having a spring also on its
back that is fixed in a convenient place to come in contact with the catch or detent &
lift it off the ratchet wheel & allow the roller to revolve & cause the windows shutters
or doors to slide, further I also make a special lock for this combination which I fix
in a suitable place to also operate on the catch or detent which lock contains a bar or
bolt that projects beyond its casing at each end. The projection on the back end of
the lock is elongated as required, when this lock is fixed on a railway or other
carriage door (or any door that is in connection with this mechanism) & is operated
upon with a key or handle the projecting end on the front of the lock fastens or locks
the door, on unlocking the door the elongated projection on the hack end of the lock
comes in contact with the catch or detent & also lifts the detent off the ratchet
wheel & allows the roller to revolve & the windows shutters or doors to slide in the
grooves.
I also use in this combination as a factor of safety balance weights & cross levers
fixed somewhat in the following manner. I make fast in a suitable place the lower
parts of one or more cross leavers the upper parts of which 1 secure to the window
shutter or door that may be required to slide, I connect the cross levers by chains

page_text: bands or such like articles after passing them over pulleys fixed on the framework to
balance weights placed in suitable positions.
I do not claim any originality of invention in the racks rollers cog wheels springs
ratchet wheels push buttons detents catches chains bands pulleys or balance weights
apart from their combination to effect the purpose required.
In order that my invention may be better understood I now proceed to describe
the drawings hereunto annexed reference being had to the figures & letters thereon.
Figure 1. (Sheet 1) shows front view of door window or shutter.
Figure 2. Section of working parts in frame.
Figure 3. Details of special lock with elongated bolt.
Having now particularly described & ascertained the nature of my said invention
& in what manner the same is to be performed I declare that what I specially
claim is
The combination of the mechanisın above described & the special lock to auto-
matically open & shut windows doors or shutters.
