PROVISIONAL SPECIFICATION.
An Improved Supporter or Fastener for Window Sashes, Sliding
"Doors, or Sliding Screens.
We, CHARLES DARGIE, of Edward Street, Shepparton, in the Colony of
Victoria, Machinist, and SIDNEY COOKE, of No. 330 Flinders Lane, Melbourne,.
in Victoria, as aforesaid, Printer's Furnisher, do hereby declare the nature of this,
invention to be as follows:-
This invention relates to an improved supporter or fastener of the type which are
employed mainly. to hold up at any desired position the window sashes of railway
and other carriages, although it may also be used upon any other sliding window
sash or slide door or screen which is not furnished with sash weights or other:"
balance contrivances.
Our improved supporter or fastener consists of a metallic ratchet faced eccentric
cam-lever having a weighted end which serves as a handle, such lever being
centred on a pin carried by a metallic slotted frame or box, similar to a sheave.
box, and which box is secured by wood screws or the like to the sash or other
frame, door or screen. Projecting from the inner upper edge of the said box-
frame is a finger piece which lies immediately above the handle end of the lever,,
and which finger piece serves as a handle to lift the sash or screen. Upon .the
inner edge of the window frame we secure a metallic ratchet bar, with the teeth of
which the aforesaid ratchet toothed cam engage, to hold up or support the sash or :
other sliding frame, door or screen.
A window sash or slide door or screen, furnished with our invention may be
lifted or slid up as ordinarily, the fastener being no obstruction to and need not be
operated in its upward movement, but immediately the sash, slide or screen has
reached the desired position on the frame the teeth on the eccentric cam, by reason
of the weighted end of the cam-lever, are caused to engage with the ratchet teeth
on the frame, and so support or fasten the sash in such position, and until such time.
as the fastener is released to lower the sash or slide, and which is accomplished
by pressing the weighted end of the cam-lever upwards towards the projecting
stud or finger piece upon the box frame. It will thus be noted that accidents
through the falling of the sashes, slides or screens will in a great degree be
prevented.

An Improved Supporter or Fastener for Window Sashes, Sliding
Doors, or Sliding Screens.
We, CHARLES DARGIE, of Edward Street, Shepparton, in the Colony of
Victoria, Machinist, and SIDNEY COOKE, of No. 330 Flinders Lane, Melbourne,
in Victoria, as aforesaid, Printers Furnisher, 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 :-
This invention relates to an improved supporter or fastener of the type which
are employed mainly to hold up at any desired position the window sashes of
railway and other carriages although it may also be used upon any other sliding
window sash or slide door or screen which is not furnished with sash weights or
other balance contrivances.
The attached drawing illustrates the invention,—
Fig. 1 shewing a front view of it as applied to a window frame and sash, and
Fig. 2 a plan of same.
Fig. 3 shews back view of the box or frame which supports the eccentric catch
and which is shewn therein and
.
Fig. 4 a side view of said box or frame.
Fig. 5 is a side view, and
Fig. 6 a face view of the back plate which carries the pin or pintle on which the
eccentric catch works.
Fig. 7 shews a side view of the box when made in one piece or casting.
The improved supporter or fastener consists of a metallic ratchet faced eccentric
cam-lever A having a weighted end A 1 which serves as a handle, such lever is
centred on a pin B carried by a back plate B 1 and the fore end of such pin
is supported by a hole C1 in a metallic slotted frame or box C and which_box is
secured by wood screws C2 or the like to the sash D or other frame, door or
screen. Projecting from the inner upper edge of the said box-frame C is a finger
piece C3 which lies immediately above the handle end A 1 of the eccentric lever A
and which finger piece serves as a handle to lift the sash or screen.
Upon the
inner edge of the window frame we secure by wood screws. El or otherwise a
metallic ratchet bar E with the teeth e of which the teeth a on the aforesaid ratchet
toothed cam A engage to hold up or support the sash or other sliding frame, door
or screen. As will be seen by the drawings the back plate B1 is made narrower
at its ends to fit into the recessed parts cat back of frame or box C. As an
alternative the box C may be made in one piece or casting as shewn in Fig. 7.
A window sash or slide door or screen furnished with this invention may be
lifted or slid up as ordinarily, the fastener being no obstruction to and need not be
operated in its upward movement, but immediately the sash, slide or screen has
reached the desired position within the frame the teeth a on the eccentric cam A
by reason of the weighted end of the cam lever are caused to engage with the
teeth e of the ratchet bar E on the frame and so support or fasten the sash in such
position and until such time as the fastener is released to lower the sash or slide.
To lower the sash or slide the weighted end A1 of the cam-lever A is pressed
upwards towards the projecting stud or finger piece C 3 upon the box frame. It
will be noted that accidents through the falling of the sashes slides or screens will
in a great degree be prevented by employing our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
(1.) A supporter or window fastener consisting of the ratchet faced eccentric

page_text: cam piece A-A1 centred on a pin B carried by a box frame C-B1 combined
with a ratchet bar E as herein described and as illustrated in our drawings.
(2.) In a window fastener a pivotted ratchet faced eccentric cam piece A furnished
with a weighted end or handle as A 1 combined with a ratchet bar as E as herein
described and as illustrated in our drawings.
(3.) In a window fastener a ratchet faced eccentric cam piece as A-A 1 centred
on a pin B carried by a box frame which is made in two parts B1 and C the latter
being provided with a finger piece C 3 as herein described and as illustrated in our
drawings.
