Improvements in or relating to the Construction of and Mode of
Fitting Window Sashes and Sash Frames.
1, JOHN INGLESON of No. 1 Stephens Road, Burmantofts, Leeds, in the County
of York Joiner, do hereby declare the nature of this invention to be as follows:-
-
This invention has reference to improvements in the construction of and mode of
fitting window sashes and sash frames, and its object is to provide simple and
inexpensive means whereby the sashes can be raised or lowered, and when required
may either separately or together, be partially or fully withdrawn from the casing
for cleaning and other purposes, yet when replaced in their races are securely held in
position when stationery or whilst being raised or lowered.
According to this invention the upper and outer sash is made narrower than the
lower and inner one to permit of the former being easily withdrawn from its race,
and I make the parting beads between the two races in two portions and of different
widths that is to say, they are made wider at their upper portions down to or about
the meeting bar, and then the lower portions are decreased in width to permit of the
upper and outer sash being withdrawn. Each pulley stile may also be stepped or
rebated to within a suitable distance of the outer lining of the frame, and the parting
bead or projections may be fixed thereon against which, and a projecting portion of
the outer lining and parting bead the outer and inner sashes are respectively made
to work.
The staff beads are also divided at a suitable distance above the meeting bar and
are hung upon suitable hooks and loops or lifting hinges so that they may be turned
into the apartment and afterwards removed from the inside lining when it is required
to completely withdraw the sashes from their races.
At or near the lower edge of each sash is screwed a trunnion to which the sash cord
(copper or otherwise) or chain is attached. Each trunnion is made to slide in the
rebated or recessed portion of the pulley stile, and is provided at its outer end with a
projecting arm or stem, which when the sash is sliding up and down in the race
is parallel therewith, but when the upper portion of the sash is drawn inwards the
latter turns on the trunnion portion of the fixing in the attaching loop of the cord
(copper or otherwise) or chain and the projecting arın passes into a suitable casting
or fixing let into the lower part of the projecting portion of the pulley stile in each
race.
I also make a portion of the lower part of the inside lining removeable so that it
(and the narrower portion of each parting bead when the outer sash is withdrawn)
may be removed when it is required to wholly withdraw the inner or both of the
sashes. When the divided lower portions of the staff beads are withdrawn pins or
projections may be inserted in that part of the inner lining covered by them, or
pieces of canvass or other suitable material attached to hooks on the inner and
lower sash, and the upper portion of the latter drawn inwards for ventilating
purposes.
By the above described improvements I am enabled to partially or wholly with-
draw each sash separately or both at the same time, and to dispense with the use
of a large pocket at the upper portion of the frame; also these improvements may
be applied to counter balanced sashes where the use of weights are dispensed with,
in which case it will be found necessary to partially or wholly withdraw one sash at
5 a time.

COMPLETE SPECIFICATION.
Improvements in or relating to the Construction of and Mode of
Fitting Window Sashes and Sash Frames.
I, JOHN INGLESON, of No. 1, Stephens Road, Burmantofts, Leeds, in the County
of York, Joiner, 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 has reference to improvements in the construction of and mode of
fitting window sashes and sash frames, and its object is to provide simple and
inexpensive means whereby the sashes can be raised or lowered, and when required
may either separately or together, be partially or fully withdrawn from the casing for
cleaning and other purposes, yet when replaced in their races are securely held in
position when stationery or whilst being raised or lowered.
In the drawings
Fig. 1. is an elevation of sashes and frame constructed according to my invention.
Fig. 2. a part section elevation of sash frame with the sashes removed. Fig. 3. a part
sectional plan. Fig. 4. a part sectional elevation showing the sashes turned inwards
for cleaning or other purposes. Figs. 5 and 6 are respectively an enlarged part side
and end elevation of a sash with trunnion applied. Figs. 7 and 8 are respectively
an enlarged elevation and transverse section of fixing for receiving the arm of the
trunnion. Fig. 9. is a part sectional elevation of an arrangement of counter-balanced
sashes.
Like parts in all the views are marked with the same letters of reference.
A Aare the upper and lower sashes which are glazed in the ordinary manner and
may be hung and made to work respectively in the races 6 b¹ of the frame B as
hereafter described. The upper and outer sash A is made narrower both in width
and depth than the lower and inner sash A' so as to permit of it being easily wholly
or partially withdrawn from its race when required.
When the sashes A A¹ are placed in position for sliding up and down in their
races as shown at Fig. 1. the frame B presents the same appearance as one of
ordinary construction, but in order to wholly or partially remove the upper sash A
from its race for cleaning or repairing purposes the races 6 6₁ are made of different
depths, that is to say the inner race 6 may be made, say about one half or five
eights of an inch deeper in the frame than the outer race 6 to permit of the sash A
being easily withdrawn. For the same purposes the parting beads CC may be
divided at or about the meeting bar D, and the lower and removeable piece c of each
bar C may be decreased in width as shown at Fig. 1.
Each pulley stile E may also be stepped or rebated the full length of the frame to
form a recess e, say about one inch and five-eighths of an inch in width (from the
staff beads F F on the inner sides of the frame, and from the parting beads CC
respectively) by about say one half or five-eighths of an inch in depth. In practice
I have found it convenient to form the above described recess e by fixing a projecting
piece e to the pulley stile E (as shown at Fig. 3), against which projections the
sliding surfaces of the sashes are made to work.
"The staff beads F F are also divided at a suitable distance above the meeting
bar D (say about an inch and five-eighths of an inch) and are hung upon suitable
hooks and loops or lifting hinges G (hooks and loops are preferred) so that they may
be turned into the apartment and afterwards removed from the inside lining when it is
required to completely withdraw the sashes A A¹ from their races.
At or near the lower edge a a¹ of each sash is screwed a trunnion H to which the
sash cord (copper or otherwise) or chain I is attached.
The trunnions H are constructed as shown at Figs. 5 and 6:—that is, to the inner
end of the circular portion H or trunnion proper is cast or otherwise fixed three
projecting (upward and horizontal) arms h, h³, which are let into the sashes and
secured thereto by screws. To the outer end of the round portion H is cast or fixed

page_text: a downward projecting arm h³ and whenever the sashes are required to be turned
inwards for cleaning and glazing purposes, as shown at Fig. 4, the lower end of the
arm h³ is made to pass within a recess j formed in a casting or catch piece J which is
let into and fixed in the projecting pieces e e¹ at or near bottom of the recess b blas
shown at Figs. 2. The catch pieces J are of different lengths for each race that in
the race b being longer than the one in race b¹ to permit of the outer sash A being
turned inwards as shown at Fig. 4. The trunnion H and arm h³ are made to pass
into the recesses e e and slide up and down therein when the sashes A A' are in a
vertical position as shown at Fig. 1, but when the upper portion of the sash is drawn
inwards the sash turns on the trunnion portion of the fixing H in the attaching
loop of the cord I (copper or otherwise) or chain, and the projecting arm h³ passes
into the recess j in the casting or fixing J.
In order to remove the inner sash A¹ completely from its race for repairing
purposes I make provision whereby a portion of the inner lining may be removed
at K fig. 1, and then the hinged portion of the staff bead is afterwards removed
whereby a recess is formed to permit of the trunnion passing out of the race b¹; and
when it is required to remove the outer sash A the lower portion of the parting
beads CC are also removed which permits of the sash being drawn forwards, and
the cords I easily detached from the trunnions H.
The staff beads F F may be retained in a closed position as shown at Fig. 1 by
means of screws for their equivalents.
When the divided lower portions of the staff beads are withdrawn pins or projec-
tions may be inserted in that part of the inner lining covered by them, or pieces of
canvass or other suitable material attached to hooks on the inner and lower sash
and the upper portion of the latter drawn inwards for ventilating purposes.
By the improvements described and illustrated at Figs. 1 to 8 I am enabled to
partially or wholly withdraw each sash separately or both at the same time, and to
dispense with the use of a large pocket at the upper portion of the frame; also these
improvements may be applied to counter balanced sashes as shown at Fig. 9 where
the use of weights are dispensed with, in which case it will be found necessary to
partially or wholly withdraw one sash at a time.
1 would have it understood that I do not limit myself to any dimension herein given
as the same may be varied as required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is.
1. The improvements in or relating to window sashes and frames consisting
essentially in hanging or attaching the sashes to looped sash cords by means of
trunnions such as H so as to be capable of sliding in a frame such as B having
stepped or rebated races such as b, band provided with divided parting beads such
as C and divided and hinged staff beads such as H H as and for the purposes
set forth.
2. A window sash frame such as B having its races stepped or rebated, its
parting beads divided and reduced, and a portion of its staff beads hinged to the
inner lining in order that the sashes sliding in its races may be readily turned
inwards or completely removed therefrom substantially as herein set forth and
illustrated.
3. The combination with a sliding window sash of a trunnion such as H and a
catch piece such as J, as and for the purposes herein set forth.
4. The window sashes and frame arranged and constructed substantially as shown
and illustrated at Figs. 1 to 8 of the annexed drawings.
Dated this Fourth day of March 1890.
