COMPLETE SPECIFICATION.
Improvements in Windows.
I, ZOTIQUE LEROUX, of 107, St. James Street, Montreal, in the Province of
Quebec, Canada, Carpenter, 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 has reference to improvements in English windows, by which they
are made to fall back into the room, to permit washing them in the apartment
where they are placed, and has for object to provide a window that is easier and
less dangerous to repair, and clean than the ordinary English window.
Referring to the drawings similar letters refer to similar parts throughout the
several views.
Figure 1 is a front elevation:
Figure 2 a vertical section:
Figure 3 a horizontal section:
Figure a vertical section shewing two windows sashes turned down into a
room:
Figure 5 a front view of my eccentric which serves to secure or release the
sashes of the windows at will:
Figure 6 a section on line x of Figure 5:
Figure 7 a section on line Y Y of Figure 5:
Figure 8 a side view of the pulley I use:
Figure 9 a front view of pulley:
Figure 10 a side view of the casting I use to fasten the weight chain to:
Figure 11 a front view of the latter, and Figure 12 an end view of this casting.
As can readily be seen by examining the drawings, the general appearance of
my window does not differ from that of the ordinary English window, in fact the
only difference is that the stopper A on the inside is in two pieces A and B, and
are only the length of the sash G, or a little shorter, as shown on Fig. 1.
recesses or grooves e extending the full height of the window frame E, serving as
guides to the stoppers A and B, when the sash G, is pushed up or down. The
stoppers A and B being shoved into or pulled out of the recesses e by means of
the excentrics F, described hereafter.
The
The upper sash H is provided with a similar arrangement of stoppers C and D
to those just described, which slide up and down in the grooves ', formed
between the shoulder e', of the window frame E, and the ordinary separator h.
As can be seen on Fig. 3, the window frame E varies from those now in use,
by having the interior face, or the one facing the sashes, inade so as to project at e,
and having the separator h flush with the projection e³, so that when the stoppers C
and D are drawn out of the recesses or grooves h', by means of the excentrics F,
the sash H can be pulled inwards.
The excentrics F, are made as shown in detail in Figs. 5, 6, & 7, and are com-
posed of the excentric proper, I, having a handle i, and pivoted on the screw i,
this excentric I turning in the space made by the two projections; and j¹ of the
plate J, the latter being slotted out at 1, so as to permit the sliding of the plate J
in the direction. To this plate J, is firmly secured the stoppers A, B, C or D
by means of a suitable number of screws j', and by one which has its head on
the under side of the plate K, as shown on Fig. 7, and thus with the screw i¹
prevents the stoppers A, B, C, or D from getting loose or shaky in any manner;
the plate K being firmly secured to the window sash G or H, by means of a suitable
number of screws k, and is provided with the slot k¹ so as to permit the passage

page_text: of the screw, when the plate J slides over the one K, so that by simply pushing
on the handle in the direction (Fig. 5) the plate J and thus the stoppers A, B,
or D are made to also move in the direction and thus move out of the recesses e
or h¹ which act as guides, the reverse operation re-inserting them into the recesses or
grooves e and h¹, it might also be mentioned that the plate K also prevents the
wearing of the wooden sash, on account of the plate J sliding on to it.
Now, instead of cords to suspend the weights L, I use chains M, which are
joined to the window sash by the casting N as shown on Figs. 10, 11 and 12, which
is securely secured to the sash by means of a screw n, the chain passing in the
channel n the bottom n³, being pierced so as to permit the chain passing through,
and as there is an eye m on its end the screw n passes through it, and thus securely
holds it in place. On each side of the channel n', I provide two side projection n³,
so that when the sashes G and H are pulled down into the room, the chains M
cannot injure the wooden sash.
However to permit the chain M to always remain on the pulley O, I make its
casting O' as shown in Figs. 8 and 9 that is provided with the curved projections o
and so that it does not matter in which way the window sash is placed, the
chain cannot help being on to the pulley wheel o, and this pulley can be laid
either end up the same as the ordinary pullies.
From the above description, it can readily be seen that to pull in a sash, the
one G, for instance all that is necessary to do is to pull in the stoppers A and B by
means of the excentrics F, and pull down the sash from the top so that it would
occupy the position shown in Fig. 4. Of course, to bring down the sash H, the
same operation is necessary.
The two sashes G and H can of course be made to occupy (when pulled in) any
position one pleases in the window frame E, that is at the bottom as shown in Fig. 4
or at the top or middle, the top positions being desirable when it is necessary to
take in any furniture through the window.
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 :-
In a window the combination of the window-frame E having the projections e,
separators and recesses e and h', and pulleys O having frames o' provided with
curved projections of with the window sashes G and H stoppers A, B, C and D,
eccentrics composed of the eccentric proper I, handle i, plates J and K and screws j
and, chains M having a ring m, weights L, castings N having a chanuel n¹
opening n³, screw n and side projections n³, substantially as described and for the
purposes set forth.
