Improvements in and applicable to Window Sashes and Frames.
We, WILLIAM PATTENDEN and ANTON RINDESLAND, trading as The Brüloo
Patent Window Co., of 5, East Row, Kensal Road, London, W., Manufacturers, 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:-
Our invention relates to improvements in and applicable to window sashes and
frames and has for its object to allow of the sliding sashes being opened in casement
form and removed when required for cleaning, glazing and other purposes, while
at the same time making the sliding sashes when closed in the ordinary manner
dust, air and water-proof.
J
The main features of our improved construction of window sashes and frames is
that all the parts are readily accessible, the cords can be easily repaired and
removed, while the sashes can be held open at any convenient height for.:
ventilation; moreover in case of fire or when removing bulky articles of furniture
or the like, the two sashes can be removed entirely thus disclosing the whole
opening of the window frame.
In carrying our invention into practice, we suspend the sashes to slips or movable:
styles capable of sliding up and down within the fixed pulley styles, each sash being
removably hinged to one of the slips at one side, while it is secured to the slip at
the other side by a bolt and a hinged strap.
These bolts can be shot into suitable openings formed in the pulley style and so
lock the sashes in position at any convenient height. The meeting rails of the two
sashes are rebated so as to fit one upon the other, being secured in that position by
any suitable sash fastener, while the meeting rail of the upper sash is provided with
a pivoted draught bead at each side fitting into a bevilled notch of the parting
bead. Hinged flaps are formed in the face of the pulley styles for the purpose of
gaining access to the weights which are separated by a suspended and removable
parting strip, cross stays being likewise provided to strengthen the pulley styles.
The bottom rail of the lower sash is snugly. located between an iron bar at the
back and a hinged weather strip in front, this iron being cut away at each side for
draining purposes.
A pin fixed into the top edge of the upper rail of the top sash enters a
corresponding opening in the window frame and thus assists in preventing
rattling.
The loose styles or slips aforesaid are provided with hooks engaging behind a
metal plate fixed in the pulley style and when the sashes are removed in casement
form, these sashes are supported on hooks or other devices fixed for this purpose at
the bottom of the pulley style, these slips being moreover prevented from running
up when the sashes are detached from them by a pin passing through openings
formed in the movable style and in the parting bead and attached by a chain to a
hook fixed to the front or face of the pultey style.

S is the upper and S₁ the lower sashes and A the pulley styles. The sashes are
suspended on the same side of the window to the movable styles or slips s by means
of hinge pintles j, two of which are provided for each sash, the pins jx (Figure 8)
of the said slips engaging moreover with corresponding openings in the sash. The
slips or runners on the other side are fixed to the sashes by the bolts d and the
hinged straps e engaging with the perforated central projection of the corresponding
T pieces e fixed to the edges of the sashes, pins being further passed through these
perforations when extra security is required.
The bolts d enter suitable openings formed in the pulley styles so that the sashes
may be locked at any height for the purpose of ventilation. The hanging styles or
slips are provided with hooks u engaging behind the plate p (Figure 2) and are
suspended to one end of the cords e, the other ends of which carry a weight W in
the ordinary manner, the two weights being separated by a parting strip b
suspended to a hook ex fixed in the head of the window.
The pulley styles A are provided with a hinged flap a in front and a cross stay i
inside to strengthen the pulley style and prevent it from bulging. The parting
bead g is formed as shewn in Figure 11 of an upper half q which is wider than the
lower half q* and bevilled at the bottom to receive the pivoted weather beads m.
A notch n (Figure 8) is formed in the hanging style g behind to prevent the bead
from being broken when first opening the sash in casement form.
. The window frame is furnished at the bottom with an iron bar Fig. 5 at the
back of the lower sash, this bar being cut away at both ends to allow the lower end
of the slips which is shaped accordingly, to fit therein snugly and to allow the water
which may gain access below the sash to drain away.
The window frame is provided moreover with a hinged weather strip k bearing
when closed against the bottom rail of the lower eash and assisting in holding the
latter tightly, preventing rattling and excluding draught and dust.
For a similar purpose, the upper sash is provided at the top with a pin n as well
as the two weather beads m above mentioned (Figures 2 and 11). To open the
sashes in casement form the weather strip k is opened, the bolt d and the hinged
strap e are removed and the sash can swing on the pintle hinges from which it may
j
be removed if desired, the slips being held down by the pin o passing through
openings formed in the pulley style and in the said slip or runners Figs. 1 & 5.
The upper sash is lowered until the bottom of the slips or runners rest upon the
hooks (Figure 5) fixed for this purpose inside the pulley style A, the bolt d of
the slips is shot into an opening formed purposely in the pulley style, the hinged
strap e is removed and the weather beads m are turned in a vertical direction, when
the upper sash can swing inwardly and be removed if desired, the slips being
prevented from running up by the inner end of the above pin o passing through an
opening formed in the said slip, the pin thus holding the two slips s in position. By
a reverse manipulation the sashes will be fixed in position again.
Figures 12 and 13 shew another method of fastening the slips s to the sashes and
is designed as a substitute for the hinge strap e (Figure 1) above described. a' is a
plate hinged to the slips on one side and furnished with a horizontal slot at the
other through which can freely pass when turned horizontally the head c¹ of the
screw c³ passing through a tapped collar d' screwed to the front of the sash S and

page_text: furnished at the end with a nut ex to prevent the screw c³ from being withdrawn
from the recess f³, in the sash. When the head c¹ is turned vertically as shewn in
the figure, the slips is tightly fixed to the sash S.
Figures 14, 15 and 16 shew another form of bolt.
The metal plate a² has its two ends at a bent up and of a size to clip the hanging
styles, said plate a³ is provided with a face slot 6 through which the neck c' of the
double nosed bolt d' d³ may work. The shank of said bolt works in and through
two slots provided in the ends as a' of the metal clip piece. One end of the bolt,
that is to say the end of the bolt that is towards the plate H is made somewhat of a
T headed form and is provided with two vertical slots ee one above and one below.
The bolt plate H, is provided with a slot corresponding to the size of the nose of
the aforesaid bolt to allow of the same being shot into and engage with it. The
second nose d³ of the bolt is plain. The plate f' is rivetted to the neck and has
the finger catch g³ whereby the bolt may be moved to and fro.
When the nose d' is drawn back and shot into the sash style, the sash can be
raised and lowered with the hanging styles, but when the bolt nose d³ is shot into the
pulley style plate H of the sash frame, the hanging style will be locked to the sash
frame and leave the sashes free to turn upon their hinges j in order to open in
casement form.
If it be essayed to raise the sash when the bolt is engaged with the plate H of
the pulley style, the slot eat the head of the bolt will engage with the fixed plate
and prevent the sash being lifted off the pintles j.
The plate H is fitted in such position that the bolt d must be shot into the pulley
style before the sash can be released from the bolt (not shewn in the drawing) on
the opposite hanging style. The slot in the lower edge of the T bolt will allow the
sash to drop for a short distance after the bolt d is shot and when the opposite bolt
may be shot also, thus working the bolts together as a check or security.
Having thus 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. The improvements in the construction of window sashes and frames, sub-
stantially as herein described and shewn.
2. In window sashes and frames the means for suspending the sashes for ready
removal in combination with the recessed parting beads, the parting strips between
the weights and cross stays in the pulley styles substantially as herein described
and shewn.
3. In window sashes and frames the means for preventing rattling and excluding
draught and dust consisting of the combination of an iron bar cut away at the sides,
and a hinged weather strip arranged at the rear and in front of the bottom rail of
the lower sash respectively with pivotted weather beads fixed at the bottom and in
front of the upper sash and bearing upon the bevilled under edges of the enlarged
or upper half of the parting bead, substantially as herein described and shewn.
4. The various means for securing the sashes to the movable styles or slips in
combination with the means for holding and supporting said slip, substantially as
herein described and shewn.
