Improvements in Frames and Casings for Window Sashes and
Blinds.
I, PETER MCKENZIE, of 466 Besserer Street, in the City of Ottawa, in the
County of Carleton and Province of Ontario, in the Dominion of Canada, Agent,
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:-
My invention relates to frames and casing for window sashes blinds and the like
for both stationary and movable structures, as houses cars carriages ships and
the like.
The object of my invention is a rattle-proof and draught-proof door, window and
blind.
Fig. 1 is a horizontal transverse section of a sash frame, casing and sash, showing
my improvements.
Fig. 2 is a vertical transverse section of the same on line x a Fig. 1.
Fig. 3 is an elevation of the rear face of the casing piece in which the sashes
slide.
Fig. 4 is a vertical transverse section of the same on line y y Fig. 3 on a larger
scale.
Fig. 5 is an elevation of the rear face of the same piece modified and
Fig. 6 is a horizontal transverse section of the same on line zz on a larger
scale.
A. A and B B are the posts and lintels of a window opening, C C and C¹ C¹ the
stops or architraves, as the case may be, B' the sill and B the top part of the
casing, and D and D' the upper and lower sash, the latter being of the ordinary
construction, except that the outer edges, d' d', of the stiles, d d, are rounded in
cross section, as shown in Fig. 1. The architraves or stops C and C₁ form a
groove, or channel with each post. Between the edges of the stiles d and the
posts A and longitudinally in the grooves or recesses are placed casing pieces E
and E, (Fig. 6) each having two grooves, e e, curved in cross section and occupying
the width of the face, so as to leave a stop between them, each adapted to receive

pieces is fitted against the post A. and to fill the space between the stops or
architraves C and C', and the groove or channel which they form with the post A
but the other, E, has its rear face provided with cushions or springs, F, of rubber
or other elastic material, which bear against the post A. Said cushions are
preferably of dovetail shape, having the broad edge or base sunk into a dovetail
groove in the piece E, so as to have a firın hold thereon, bearing with their
narrower edge on the post A and they may either be placed transversely at
convenient intervals apart, as shown in Figs. 3 and 4, or a pair of them is placed
longitudinally in the rear face of the piece, as shown in Figs. 5 and 6. Cushions,
in the shape of rubberheaded nails, G, are also placed at intervals between the stop
or architrave C so as to bear on the cushioned piece E, or in the latter so as to
bear on the stop or architrave.
The cushions F exert a continuous moderate pressure on the piece E, which in
turn presses the sash against the piece E' and that against the contiguous post A,
thus preventing rattle and making tight joints between pests A, pieces E and E
and the sash stiles, while the cushions G press the cushioned piece E against the

page_text: opposite stop or architrave C¹ making a tight joint between the latter and said
piece.
The place of the sashes D and D¹ may of course be taken by doors or blinds.
The piece E' may be cushioned like the piece E if desired. The cushions F and G
may be replaced by springs.
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 1
claim is :-
1. In frames and casings for sashes and blinds, the combination of two posts or
casing pieces forming two parallel sides of the opening of architraves or stops
forming a groove channel or recess with each, casing pieces E and E' fitting in
said recesses or grooves and having their opposing faces provided with grooves
rounded in cross section and adapted to receive the edges. of the stiles slidingly,
elastic cushions secured to the rear face of one of said pieces and bearing on the
contiguous post or piece and elastic cushions inserted in the joint between said
cushioned piece and the architrave or stop forming one side of the channel groove
or recess in which said piece is placed, and the sashes or parts having stiles with
rounded edges sliding in, the rounded grooves of said pieces, substantially as set
forth.
2. The combination of the posts A each with stops C C¹ forming a channel or
recess, pieces E and E' having their opposing faces provided with grooves e
rounded in cross section and adapted to receive the stiles of the sash slidingly,
elastic cushions F secured to the rear face of one of said pieces and bearing against
the contiguous post, cushions G in the face joint between said piece and one of the
stops and secured to one of them and the sashes D and D' having the edges of
their stiles rounded to fit aud slide in the curved grooves of said pieces, sub-
stantially as set forth.
3. The combination of a piece A and two stops C and C₁ forming a channel or
recess, a piece E fitting loose in said groove or channel and elastic cushions F
secured to the rear face of said piece, substantially as set forth.
4. The combination of a piece A forming one side of an opening, stops C and C¹
forming a groove or channel therewith, a piece E fitting loose in said groove or
channel, elastic cushions F in the rear face of said piece and bearing against the
piece A. and elastic cushions G in the face joint between said piece and one of the
stops, substantially as set forth.
5. The combination of a piece A forming one side of an opening, stops C C
forming a groove or channel therewith, and a piece E' fitting in said channel and
having two grooves of curved cross section adapted to receive the stiles of the sash
slidingly, substantially as set forth.
6. The combination of a piece E having one face occupied by two grooves e of
curved cross section and elastic cushions F inserted in the opposite face, sub-
stantially as set forth.
