PROVISIONAL SPECIFICATION.
A New Window Sash Holder with Burglar Proof Bolt.
JOSEPH THOMAS NICHOLLS Ironfounder 16ª Charles Street Northampton Square
Clerkenwell in the County of Middlesex do hereby declare the nature of this
invention to be as follows
My Invention consists of a new method in raising and lowering Window Sashes,
sliding doors and shutters in a vertical position, also applicable for Railway and other
carriage Windows, whereby all sash lines, springs, cog wheels, Pulleys and all such
appliances are entirely dispensed with. I fasten to each side of the window Sash a
wedge made of wood, Iron, or any other metal-pressing against the wedges are two
weights made of Iron or any other metal attatched to the weights are two arms fixed,
(also made of Iron or any other metal) parrallel to each other fastened in a diagonal
direction to the window frame the arms are fastened to the window box. When the
window is raised or lowered the weights move automatically upward or downward
in a diagonal direction against the wedges on either side thus securing the window
in any position required.
For Burglar proof Bolt I make a hole in the side of Window Sash at the top of
the wedge opposite to this I make a hole in the window frame 1 bore a small round
hole into window box inside the house through which I insert a key this key fits on
a piece of Iron with a cam at the end and this cam fits into a bolt or piece of Iron
at right angles to it. By turning the key the bolt is moved horizontally over the
top of the wedge through window frame and into window Sash thus effectually
securing the Window.

I JOSEPH THOMAS NICHOLLS Ironfounder 16 Charles Street Northampton Square
Clerkenwell in the County of Middlesex 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:-—
My invention consists of a mechanical contrivance applicable to window sashes,
sliding doors and shutters of every description acting in a vertical direction, it can
also be applied to any apparatus that may require opening or shutting for
ventilation &c.
It is for the purpose of holding open or closed to any extent required, such sashes,
doors, or shutters and it is adapted to windows, doors, shutters &c. in any movable or
fixed place or thing, it is suitable to dwelling and other houses or buildings, Railway
and other carriages, Ships and, vessels of every kind.
The advantages. of my invention are that it entirely dispenses with the use of all
sash-lines, Springs Cog-wheels, Pulleys &c. and its construction is strong and simple
-not easily injured or put out of order and can be fitted to any ordinary window,
door or shutter.
