Improvements in Window Fittings.
.1 JAMES LUMSDEN of 138 John Street Aberdeen N.B. Brass-founder 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 aud by the
following statement :-
My invention relates to improvements in window fittings, and has for its object
the provision of means for allowing the sashes to be reversed for cleaning or other
purposes. Suitable fittings are made of metal or such like substance of a form and
shape, and used or applied as hereinafter described.
The frame is shewn at Figs. 8. & 9. lettered g in both figures, shewing a section
of the sashes as seen from the side resting on the catches or studs; but with the
moulding closed and locked at bottom by the minor catch. a¹ is part of a hinged
moulding on bead rod permanently fixed to sash frame. a is part of sash frame not.
hinged to allow sashes to be folded down. b is the front or lower sash, o the upper
or outer sash, d the outer facing and e the sill of the window frame. Fig. 9 in
which similar letters refer to similar parts as in Fig. 8, shews the hinged
moulding a' open and the sashes folded down in a horizontal position one above.
the other.
.
In the window frame the parting beads are so far dispensed with, and the front
mouldings are hinged on detachable; but for greater security in regard to moving
the sashes I employ a lock catch which is shewu at Fig. 3 on the annexed drawings..
The use of this catch is to prevent the moulding being accidentally turned outward..
It will be seen that the main catch cannot be withdrawn, (allowing the window
to slide) until the minor or lower catch is first moved. In the fig. A is the main
catch, B the lower or minor catch which is moved in the direction indicated by the
dotted lines; C is the frout plate, and D a depression countersunk to allow the
catch to be flush with the top plate. Fig. 7 is a plate which is fixed to front
moulding to enable it to be locked by catch B on Fig. 3. A modification of this.
catch is shewn at Figs. 4 & 5 where similar letters refer to similar parts, but in
these the locking arrangement is not carried into effect. The form of the catch
for the modifications is shown at E, and F, in Figs. 4 and 5, respectively. This.
form of catch I prefer to fix near the lower or bottom end of the sash frame while
additional security is obtained by the use of a sliding catch-having rounded ends.
as shewn at Fig. 6-fixed at the upper part of the sash frame. The purpose of
these catches is to secure the hinged flap or moulding when the window is in place
and by unfastening to allow it to turn outward when the window is to be reversed.
or removed. Another fitting is shown at Figs. 1 and 2 which takes the form of a
shoe to be affixed at the corners of the sash; these act by turning on the main.
catch of Figs. 3, 4 and 5 which is of a suitable shape to engage them.
In applying my invention to sliding sash windows I place the shoe in such a
manner that turning upon the catch or projection the window is allowed to fall
downward into the room. This however cannot be done without removing the
hinged moulding, nor can this moulding be moved muless the controlling catches
previously described are operated. The lower sash is moved easily inwards from
its usual position while the top sash is brought down to nearly the level of the lower
eash before reversing.

page_text: Having now particularly described and ascertained the nature of my said
invention andlin what manner the same is to be performed I declare that what I
claim is :-
1. A locking catch for reversible window frames as described and illustrated
substantially, and as set forth.
2. A sliding catch having rounded and bevelled ends as described and illustrated
substantially, and as set forth.
8. A shoe or socket fitting as described and illustrated substantially, and as set
forth.
4. The combination of the several parts, locking catch, sliding catch, and
shoe or socket fitting for the purposes specified substantially, and as set forth.
Dated this 22nd day of April 1896.
