Improvements in Windows.
We, LEWIS SEELEY BRADSHAW, Contractor and Builder, and SAMUEL JAMES FELL,
Salesman, both of Buffalo, County of Erie, State of New York, United States of
America, 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 improvements in windows in which both the upper
and lower sashes are counterbalanced by weights and which are adapted to slide up
and down in the frame; and it has for its object to provide means whereby the lower
sash may be hinged to one side of the frame, so that it may be swung inwardly into
the room to permit washing or repairing without the necessity of getting outside the
windows.
To this end the invention consists in certain novel details of construction and
combinations and arrangements of parts, all as will be now described, and the
particular features of novelty pointed out in the appended claims.
In the accompanying drawings, Figure 1 is a perspective view of a window-frame
and sashes, showing my invention applied thereto. Fig. 2 is a similar view showing
the sashes swung inward with weight-cords detached and held on side of window-
frame. Fig. 3 is a detail perspective view showing the manner of coupling the
sashes so that they may be swung in together. Figs. 4 and 5 are detail views,
respectively, of the hook and cooperating socket-plate. Figs. 6 and 7 are sectional
views on the lines x x and y y of Figs. 4 and 5 respectively. Fig. 8 is a sectional
view of the window-frame, showing the manner of securing the facing strips or stops.
Fig. 9 is a detail view of the weight-cord-holding device.
Similar letters of reference in the several figures indicate the same parts.
The letter A represents the window-frame, B and C the upper and lower sashes,
respectively, sliding in the frame, and D the cords attached to the sashes and
carrying the counterweights, all of which are of well-known construction, and need
no further description.
Secured to the side of the lower sash C, near the bottom, is a hook E, a similar
hook being also secured to the window-frame at a point near the top of the lower
sash. These hooks, as will be seen from Figs. 4 and 6, have the curved portion e
bent out of the plane of the body or shank portion e. These hooks are adapted
to enter and cooperate with recesses in the frame and sash, respectively, to form
a hinged joint, and these recesses are preferably covered by escutcheons or plates F,
which are formed with a lip f, as shown in Figs. 5 and 7.
When it is desired to swing the sash inward, it is first raised until it clears the
sill-strip G and the points of the hooks E come opposite the openings in the plates F.
The sash is then turned, the point of the hook striking the lip of the plate
and being guided thereby until it enters the opening, and by having the hook
curved, as above described, the weight of the sash will tend to turn the sash
inward.
As shown in the drawings, we preferably place one hook on the frame and one on
the sash, the one on the frame pointing upward and the one on the sash pointing

page_text: downward, (see Fig. 1,) the cooperating socket-plates being placed likewise on the
frame and sash. By this arrangement when the sash is swung into the room the
weight of the sash is sustained by the hook at the bottom of the sash pressing
against the socket-plate on the frame and the socket-plate at the top of the sash
pulling against the hook on the frame, thus holding or locking the sash so that it
cannot fall out.
Of course it will be understood that before the sash is swung inward the weight-

cord is detached from the sash and the facing strip or stop is removed.
that the strip may be readily removed, there are secured to its inner side headed
pins H, which are adapted to enter and be held within the resilient socket H¹ in the
frame, as will be readily understood.
To hold the weight-cord when detached from the sash we provide a plate J, secured
to the window frame, having two depending hooks j, under which the cord is slipped,
the weight drawing the cord tightly under the hook and holding it, as will be
understood.
Thus far we have described only how the lower sash may be turned inward on its
hinges. When it is desired to turn in the upper sash also, said sash is first lowered
until the top is even with the top of the lower sash, when the two are locked
together. The means that we preferably employ for locking the sashes together
consists of a keeper K, secured to the top or side of the lower sash, and a swinging
latch K¹, secured to the top or side of the upper sash, having an upturned end k,
and when the latch is turned under the keeper the upturned end of the latch will
catch behind the edge of the keeper and prevent the separation of the sashes as will be
readily understood. The two sashes, having been locked together and the parting-
strip having been removed, the two sashes may be turned in, the lower sash
hinging on the frame as previously explained and the upper sash being supported
thereby.
As will be seen the device is simple, can be easily and readily applied to any
window, and does not interfere with the ordinary working of the window.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is
1. In a window the combination with the frame having the socket-plate and hook
secured thereto, of the sliding sash also having a hook and socket plate secured
thereto, cooperating respectively with the hook and socket-plate on the frame to form
a hinge-joint substantially as and for the purpose set forth.
2. In a window the combination with the frame and sash of the hooks secured
thereto having the curved portion bent out of the plane of the body or shank, and
the cooperating socket-plates secured to the frame and sash; substantially as and
for the purpose set forth.
3. In a window the combination with the frame and sash of the hooks and the
socket-plates secured thereto, said socket-plates having the lip; substantially as
described.
