PROVISIONAL SPECIFICATION.
Improvements in the Means of Holding, Locking, and Operating
Window Sashes.
I, GEORGE BRASSE of 17, Queensbury Street, Essex Road in the County of
Middlesex, Cabinet Maker, do hereby declare the nature of this invention to be as
follows:-
--
My invention relates to certain improvements in the means of holding locking
and operating window sashes.
With the object of holding the sash open in any desired position I provide in
place of the usual balance weights and cords, a rack preferably formed in the wood
on each side of the sash (though it may be of metal) which rack engages with a
spring or spring operated catch of some suitable description attached to the side of
the frame in which the sash slides, the rack being preferably of undulating form or
being so formed that the catch will yield to allow of passing the rack when the
window is raised or lowered, the spring however being of sufficient strength to hold
the window at any point. To lock the window at any point (including its closed
position) I arrange a loose pin or bolt on the inside of the frame which may be
forced in to prevent the spring or catch being pushed back by the rack.
In the case of a very heavy window where it may be desirable to provide means
for easily raising and lowering or operating same I may employ in place of the
spring a toothed wheel which engages with the rack (in this case preferably a metal
one) which wheel in turn is operated by a handle placed on the inside of the frame
a suitable pawl or other device being employed for holding the wheel from
movement when the window has attained the desired position.
To enable the sashes to be readily removed for cleaning purposes or for
examining the parts above described, I prefer to secure the beading which retains
the sashes by screwing same in place instead of nailing as is customary.

COMPLETE SPECIFICATION.
Improvements in the Means of Holding, Locking, and Operating
Window Sashes.
I, GEORGE BRASSE, of 17 Queensbury Street, Essex Road, in the County of
Middlesex, Cabinet Maker, 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 relates to certain improvements in the means of holding, locking
and operating window sashes the object being to euable the sash to be held open in
any desired position by other means than the usual balance weights and cords.
To clearly explain my invention reference is made to the accompanying drawing
in which is illustrated one form of my invention and in which-
Fig. 1 is a sectional elevation of a window frame and sash, and

page_text: In carrying out my invention I form preferably in the sash a, though it may be
in the frame, a rack b, either in the wood on each side of the sash, or of metal let
into the sash, which rack engages with a spring catch, or a spring operated catch
of some suitable description. As shown this consists of a spring plate a carrying a
rounded nosed projecting through the plate e, a small spring f being provided
if desired, to deaden the noise which might be otherwise made on the return of the
-spring c.
This catch is preferably let into the side of the frame y as shown, or it may be
into the sash. The rack b is made of an undulating form in order that the nose of
the catch may work freely in same in whichever direction the sash is moved, the
spring of the catch however is of sufficient strength to hold the window at any
point.
To lock the window in any position a pin or bolt is placed in the side of the
frame such pin sliding in a box or casing in such a manner that its end may be
placed behind the catch to prevent its being pushed back by the rack. This
provides an efficient sash fastener and one which is difficult to open from the
outside if the window is closed without removing the glass. In the case of the
upper sash the loose pin is made longer than the one for the lower sash so that
it may pass through behind that part of the frame in which the upper sash
travels.
In the case of a very heavy window where it may be desirable to provide means
for easily raising and lowering or operating same I may employ in place of the
spring catch or in addition to same a toothed wheel which engages with the rack
(in this case preferably a metal one) which wheel in turn is operated by a handle
placed on the inside of the frame a suitable pawl catch or other device being
employed for holding the wheel from movement when the window has attained the
.desired position.
To enable the sashes to be readily removed for cleaning purposes, or for
examining the parts above described, I prefer to secure the beading which retains
the sashes by screwing same in place instead of nailing as is customary.
I am aware that it has before been proposed to provide a window sash with a
rack and catch and I do not broadly claim the employment of same but―
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a window sash and frame the rack, the spring catch engaging therewith
and the sliding stop arranged to prevent the catch from being moved by the rack all
constructed and arranged substantially as and for the purpose described.
2. The improvements in the means of holding locking and operating window
sashes substantially as described.
