Improvements in Reversible Windows.
We, ANNE TOMLINSON, widow of the late Christopher Tomlinson, Builder, of
Camp Fields, Holbeck, in the City of Leeds, and WILLIAM PHILLIPS, of 2, Yarm
Street, in the City of Leeds, 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 refers to a double rebated weather proof joint for reversible
windows, either fixed or sliding.
We first rebate the inside edge of the sashrstile about " by ", then rebate the
jambalong the adjoining edge in a similar manner. We fix a flanged pivot about
the centre of each, and then attach a double rebated slip or bar, in two portions;
the top part above the pivot being fixed on the sash, and the lower part on the
jamb, thus forming a double check on the draught. We prefer also to make a
plough or groove on the inner side of the sash stile. beyond the rebate; and a
similar plougli or groove on the adjoining side of the jamb immediately opposite
the plough or groove in the sash stile, to form a baffle for the draught, as is already
frequently done in window joints:
The accompanying drawings, with reference letters, are hereto annexed in
order that the invention and the manner in which the same is to be performed
may be more readily understood. In these drawings Fig. 1 is a view of the
side of the sash stile adjoining the window jamb. Fig. 2 is a view of the side of
the window jamb adjoining and facing the sash stile, with the sash stile over
it in an inclined position. Fig. 3 is an outside view of the window jamb, and
Fig. 4 is an outside view of the window stile, whilst Fig. 5 is an outside view of
both window jamb and window stile, when the latter is hinged' to the former;
sections above and below the hinge being included in this figure.
In all the figures the same reference letter refers to the same part.
J, indicates the window jamb, and
S, indicates the window stile.
a, is the plough or groove formed in the window jamb, and b, is the similar
plough or groove in the window sash stile directly opposite and facing the plough
or groove a, in the window jamb.
c, d, is the double rehated slip or bar, fitting the above mentioned rebates in the
window sash stile and jamb; the top part c, above the hinge being fixed to the
window sash stile, and the lower part d, to the window jamb. This double
rebated slip or bar c, d, thus covers and protects the inner line or inside of the
window joint; whilst the two ploughs or grooves a, and b, form an eddy or
baffle opening in the middle of the line of the window joint, as best seen in the
sections.
In order to make the hinge or pivot weather proof, we make use of the flanged
pivot shewn in the drawings; the socket half g, which is attached to the window
sashi stile, having the flange produced beyond the socket above the socket, as
indicated at, in Fig. 4, and recessed back an equal distance from the face of the
socket below the socket, as indicated at n, in Fig. 4: whilst the pin half h, of the
flanged pivot has the flange correspondingly recessed back above, and produced
beyond the joint of the pivot below, as shown at m, and' p, in Fig. 3.

page_text: It will be evident, that if the window is made to swing in the opposite direction
to that shewn in the drawing, the top part c, of the rebated slip or bar must
be attached to the window jamb, and the lower part d, to the window sash. Also
the draught, in passing from the outside, is first checked by the plough or groove
opening a, b; but on reaching the rebated slip or bar c, d, must pass round three
corners before emerging into the room; and is therefore much more effectually
checked than by the present modes of forming the joints of reversible windows.
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
wo claim is-
1. In joints for reversible windows the use of a double rebated slip or bar c, d,
fitted in corresponding rebates on the adjoining inside edges of the window sash
stile and window jamb, of which the part on one side of the sash pivot or hinge
is attached to the window sash stile, and the part on the other side of the pivot or
linge attached to the window jamb, substantially as herein set forth and illustrated.
2. The combination with the subject matter of Claim 1, of a double plough or
groove a, b, substantially as herein set forth and illustrated.
3. In combination with the double rebated slip or bar claimed in Claim 1, the
use of a flanged pivot, having the flanges of the pin and socket halves projecting
and recessed substantially as herein set forth.
