Improvements in or relating to Window and like Fasteners.
I, JOSEPH ALEXANDRE LONGUE, Gentleman, of Voiron, Department of Isère,
in the Republic of France, do hereby declare the nature of this invention to be
as follows:
When a window say a French window, is being closed-whether it be provided
with bolts or catches it frequently occurs that it is very difficult to push the
locking part down to the bottom or more particularly to cause the ends of the
bolts of the locking device or the arms of the pivotted rod to enter into their
keepers.
It also happens that when the window is closed and it is desired to open it,
great difficulty is sometimes found in doing so, if the wood has become swollen
or warped.
In order to avoid this double drawback, I provide the hooks or arms of the
revolving or pivotted rod or the ends of the bolts, as the case may be, with
rollers which engage with inclined planes or curved surfaces provided for the
purpose in their respective keepers.
In such manner the manipulating of the fastening device consisting of a pivotted
rod or of a fastening device constituted by two bolts moved in reverse directions
by a turn-button or handle causes the rollers to engage between the inclined
planes or curved surfaces on which they roll, whereby also the leaves
or halves of the window are caused to approach or move away from, each other
according to whether it is desired to close or to open the window, and this takes
place without any great effort or rough usage of the window or its locking parts
or danger of breaking the glass.
In the practical application of my invention I bend obliquely or arch the ends of
the bolt and I provide them with a roller which is adapted to engage with a keeper
or retaining plate secured on the architrave or framing of the window; the inner
surface of the keeper has either inclined planes or a suitable curved passage over
which the roller passes; the keeper is provided at its inner end with a recess
having vertical walls to receive the roller, and the bent or curved part of the
bolt terminates in a heel or suitably shaped part which can rest against one of
the vertical walls of this recess.
The operation of closing the window is the same as usual; but when its two
leaves are sufficiently near, the handle of the locking device is turned; the roller
rolls on the curved surface or on the inclined plane of the keeper and causes the
leaves to close completely, the roller finally coming into the recess in the keeper
and the heel of the bolt resting on one of its faces against the side of the recess,
thus preventing the opening of the window under any shocks, such for instance
as that of the wind; and thus resisting the pressure caused by any such shocks.
To open the window the handle is turned in the opposite direction: the roller
how slides on the other curved surface or on the other inclined plane causing the
eaves of the window to open without the necessity of pulling the handle, until
.מ

page_text: the roller becomes disengaged from the keeper when the window may be easily
cpened.
In cases where a pivotted rod is employed, said rod is provided at each end with
a hook or curved arm carrying at its end a roller which is adapted to roll on one or
other of the two curved surfaces of the keeper which surfaces are secured to, or formed
in a recess in which the roller is adapted to engage, the end of the curved arm
having the shape of a heel which is adapted to rest against the inner wall of the
recess thus preventing the opening of the window under any shocks of wind or
the like.
The operation is the same as that described for the locking devices consisting
of two bolts reversely actuated by a turn-button or handle with the exception
that the handle of the rod has to be operated instead of the handle of the bolts
in order to open the window.
The two devices described are similar, but. the first operates in a vertical and
the second in a horizontal direction.

COMPLETE SPECIFICATION.
Improvements in or relating to Window and like Fasteners.
I, JOSEPI ALEXANDRE LONGUE, Gentleman, of Voiron, Dep. Isère, in the
Republic of France, 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:-
When a window say a French window, is being closed--whether it be provided
with bolts or catches it frequently occurs that it is very difficult to push the
locking part down to the bottom or more particularly to cause the ends of the
bolts of the locking device or the arms of the pivotted rod to enter into their
keepers.
It also happens that when the window is closed and it is desired to open it,
great difficulty is sometimes found in doing so, if the wood has become swollen
or warped.
In order to avoid this double drawback, I provide the hooks or arms of the
revolving or pivotted rod or the ends of the bolts, as the case may be, with
rollers which engage with inclined planes or curved surfaces provided for the
purpose in their respective keepers.
In such manner the manipulating of the fastening device consisting of a pivotted
rod or of a fastening device constituted by two bolts moved in reverse directions
by a turn-button or handle causes the rollers to engage between the inclined
planes or curved surfaces on which they roll, whereby also the leaves
or halves of the window are caused to approach or move away from each other
according to whether it is desired to close or to open the window and this takes
place without any great effort or rough usage of the window or its locking parts
or danger of breaking the glass.
In the accompanying drawing.
Figure 1 is a vertical section of a closing device with latch and casing or
keeper.
Figure 2 is an elevation of Figure 1..
Figure 3 is inverted plan of the guiding keeper.
Figure 4 is a modified construction of a keeper with oblique opening.

page_text: Figure 5 is a horizontal section of a closing device with a pivotted bolt.
In Figure 1 the upper end of the latch or bolt a is bent and provided with a
roller which is adapted to engage with a keeper or retaining plate o secured on
the architrave or framing of the window; the inner surface of the keeper has
either inclined planes c¹ and c² or a suitable curved passage over which the roller b
passes; the keeper e is provided at its inner end with a recess having vertical
walls to receive the roller, and the bent or curved part of the bolt a terminates
in a heel or suitably shaped part a' which can rest against one of the vertical
walls of this recess c³.
The operation of closing the window is the same as usual; but when its two t
leaves are sufficiently near, the handle of the locking device is turned; the
roller & rolls on the covered surface or on the inclined plane of the keeper and
causes the leaves to close completely, the roller b finally coming into the recess c³
in the keeper and the heel of the bolt, a, resting on one of its faces against the
side of the recess thus preventing the opening of the window under any shocks,
such for instance as that of the wind; and thus resisting the pressure caused by
any such shocks.
To open the window the handle is turned in the opposite direction; the roller b
now slides on the other curved surface or on the other inclined plane c2 causing
the leaves of the window to open without the necessity of pulling the handle,
until the roller b becomes disengaged from the keeper e when the window may
be easily opened.
In the arrangement shown in Figure 4 the edge of the opening of the keeper e
is oblique as well as the edge of the guide for the bolt a which rests on the former
when the window is being closed.
In this arrangement when the window is being closed, the roller & engages
automatically with the keeper e without necessitating any special manoeuvre of
the handle of the bolt, and rises on the inclined plane as in the preceding
construction, so that in order to close and lock the window it is sufficient to push
the leaves without having to touch any of the parts of the closing device.
In this construction (Figure 4) the bolt or latch a carries a small tenon or
hook which can slide in a groove el of the guide e (Figure 3) the length of said
groove regulating the travel of the bolt a and roller b.
In Figure 5 the bolt a of a locking device with pivotted bolt, is provided at
each end with a hook or curved arm a carrying at its end a roller b which is
adapted to roll on one or other of the two curved surfaces c¹, ca of the keeper c
which surfaces are secured to or formed in a recess in which the roller b is
adapted to engage, the end of the curved arm a² having the shape of a heel a¹
which is adapted to rest against the inner wall of the recess e thus preventing
the opening of the window under any shocks of wind or the like.
To close the window, its leaves are suitably brought near each other and the
handle of the pivotted bolt turned; the hook a turns taking with it the leaves
of the window which close completely without being pushed and finally the roller b
engages with the recess e and the heel a' prevents the window opening without
the pivotted bolt being operated.
In opening the roller & rolls on the path o causing the leaves to participate
in its movement, which will be easily understood if it is taken in consideration
that the curvature of said path is smaller than that of the path which the roller
would describe if it were free.
The arrangement for the closing device with pivotted bolt is therefore similar
to that with latch.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
A window or like fastener with sliding and pivotted latches characterised by
the arrangement on the upper and lower architraves of the window frame of casings

page_text: or keepers provided internally with inclined or curved paths which engage rollers
arranged at the curved or inclined ends of the sliding latches or pivotted hooks,
the keepers being moreover provided with recesses for the rollers, the heels, of
the latch or hook resting against one of the walls of said recess substantially as
described and for the purpose specified.
2. The oblique arrangement of the edge of the guiding keeper for closing
devices and sliding latches, enabling the leaves to be closed and locked by simply
pushing them substantially as described.
