Year: 1899

page_text: I, ALEXANDER FORIN, of Nelson, in the County of Kootenay, in the Province of
British Columbia, Dominion of Canada, Physician and Surgeon, do hereby de-
clare the nature of this invention to be as follows:-
My invention has for its object to provide sliding window sashes with fasteners
which will serve both to retain the sashes at any height to which they may be
adjusted, and when the window is closed to oppose the raising of the lower sash
and the lowering of the upper sash and thus prevent the window from being sur-
reptitiously opened from without.
The invention consists in combined sash fasteners and holders each comprising
a rotatable pawl mounted in bearings in the window jamb, the one pawl nor-
mally engaging the lower sash when such sash is raised, while the other pawl
normally engages the upper sash and prevents the same from being lowered, and
being of such length that when turned down or reversed its free end will abut
against the meeting rail of said sash and thus fasten the sash in the closed position.
The fastening and holding devices are mounted in boxes or casings which are
received in recesses in the window jamb. These casings are formed with bear-
ings in which spindles carrying the wedge shaped pawls are journalled.
Notched strips are secured to the stiles of the sashes, adjacent the casings,
the pawls being brought into engagement with the notches thereof to hold the
sashes at different elevations.
In order to normally hold the pawls in engagement with the notches I provide
leaf springs which bear against the rear sides of the pawls when the latter are in
upright position, and in order to release the pawls at any time to move the sashes
towards their closed positions I provide handle rods whose ends are squared and
received in correspondingly shaped sockets of spindles to enable the latter to be
rotated. The rods extend into the room through the jamb and have knobs on
their inner ends, and escutcheons in which they turn.
One of the principal objects of my invention is to so mount the lower pawl
that it will hold the lower sash securely locked when in closed position, and
to this end I locate the casing at such a point in the jamb that when the pawl
is reversed or turned down its point will rest upon the upper or mid-rail of the
lower sash, thereby preventing the lower sash from being raised until the pawl
is turned and freed from said rail.
It will be seen therefore, that the lower pawl is not only useful in holding
the lower sash raised at different elevations, but is capable of performing the
additional function of locking the lower sash closed.

page_text: I, ALEXANDER FORIN, Physician, of Nelson, British Columbia, Canada, 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 for its object to provide sliding window sashes with fasteners
which will serve both to retain the sashes at any height to which they may be
adjusted, and which when the window is closed will oppose the raising of the
lower sash and the lowering of the upper sash and thus prevent the window
from being surreptitiously opened from without.
The invention consists in combined sash fasteners and holders each comprising
a rotatable pawl mounted in bearings in the window jamb, the one pawl nor-
mally engaging the lower sash when such sash is raised, while the other pawl
normally engages the upper sash and prevents the same from being lowered, and
being of such length that when turned down or reversed its free end will abut
against the meeting rail of said sash and thus fasten the sash in the closed
position.
Reference is to be had to the accompanying drawings, in which Figure 1 is
a face view of the holder for the lower sash, shown detached. Figure 2 is a
detail side view of the lower pawl. Figure 3 is an edge view thereof.
Figure 4
is a transverse vertical section of the lower holder detached. Figure 5 is a hori
zontal section on the line 1-2 Figure 1. Figure 6 is a face view of the upper
sash holder. Figure is a side view thereof. Figure 8 is a sectional side
elevation of the same in locking engagement with a notched strip. Figure 9
is a face view of said strip, and Figure 10 is a face view of a window sash with
my improved sash holder shown in locking engagement with the mid rail of
the lower sash.
Recesses are made in the window jamb J and between the guiding strips for
the sashes to receive the casings C and C, in which are located the fastening
and holding devices, the one casing C which is placed at a lower level than the
other being arranged for the fastening devices of the lower sash and the other
casing C being adapted for the fastening devices of the upper sash, as will be
hereinafter more fully explained.
These casings are formed with journal bearings d and d¹ in which are jour-
nalled the spindles a and a¹ respectively, of wedge shaped pawls A and A¹ secured
fixedly to or formed integral with such spindles.
Notched strips such as F (Figure 9) are secured to the stiles of the sashes,
adjacent to the casings C and C, the pawls being brought into engagement with
the notches thereof to hold the sashes at different elevations.
In order to normally hold the pawls in engagement with the notches I provide
leaf springs e and e¹ which normally bear against the rear sides of the pawls when
the latter are in upright position, and in order to release the pawls at any time
to move the sashes towards their closed positions I provide handle rods B and B¹
whose ends are squared and received in correspondingly shaped sockets b, b¹ in
spindles a and a¹ to enable the latter to be rotated. These rods extend into the
room through the jamb and have knobs E on their inner ends, and escutcheons D
in which they turn.
One of the principal objects of my invention is to so mount the lower pawl that
it will hold the lower sash securely locked when in closed position, and to this
end I locate the casing C at such a point in the jamb that when the pawl A is

page_text: reversed or turned down as shown in Figure 10, its point will rest upon the
upper or mid-rail of the lower sash, thereby preventing the lower sash from
being raised until the pawl is turned and freed from said rail.
It will be seen, therefore, that the lower pawl A is not only useful in holding
the lower sash raised at different elevations, but is capable of performing the
additional function of locking the lower sash closed.
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 :-
1. The herein described sliding window sash fastener consisting of angular
spring pressed pawls, one for each sash, separately mounted to rotate in bearings
in the window jamb and each adapted to engage a rack on its appropriate sash,
the pawl for the upper sash when in its normal position preventing the lowering
of said sash and the pawl for the lower sash when the window is closed bearing
on the meeting rail of said sash so as to prevent it from being raised, substantially
as specified.
2. A sash holder and fastener consisting of a pawl of the form represented rotat-
ably mounted in a bearing in the window jamb at a point above the lower sash
when the sash is closed and adapted to engage with said lower sash when the latter
is raised, and of such length that when turned down or reversed into vertical
position its extremity will abut against the mid-rail of the lower sash and thus
fasten such sash in its closed position, as set forth.
