PROVISIONAL SPECIFICATION.
Improvements in Combination Window Sash Fasteners and Draught
Excluders.
JOHANN WILHELM LUDWIG ROHDE Wilhelmsruh Clapham Common South
Side S.W. Inventor do hereby declare the nature of this invention to be as
follows:-
My invention consists of a specially constructed bracket made of metal or any
other suitable material, which is formed in such a manner that it can be screwed
or otherwise fastened on to the inner side of a window sash, being of sufficient
length to stand out and turn over the sash bead which keeps the sash in its position,
the portion which turns over the bead being of sufficient length to take a set screw.
I then provide a plate of any suitable size or shape which is screwed or otherwise
fastened on to the frame (being level with the inside of said bead) and which is
furnished with a hole not pierced through but of sufficient depth and size to allow
the point of set screw to enter. The aforesaid bead having been provided with a
facing of any suitable draught excluder such as rubber or felt which comes into
contact with the sash, the set screw is screwed against the aforesaid plate and in
so doing the sash is drawn forcibly towards the bead firmly pressing it against the
draught excluder thereby preventing any draught from entering and at the same
time rendering it impossible to raise the sash and effectually preventing the sash
being shaken by wind or vibration. By releasing the set screw so that it becomes
quite free of the plate the window can be raised in the ordinary manner.
This description applies to the lower sash but the bracket can be applied in like
manner to the upper sash.
Dated this 15th day of January 1895.

JOHANN WILHELM LUDWIG ROHDE Wilhelmsruh Clapham Common South
Side S.W. Inventor 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:-
In the following description my reference is to Fig. 1. which is a section taken ou
line 1. 1 of horizontal drawing shewn in Fig. 2. and on which corresponding letters
denote corresponding parts. My invention consists of a specially constructed sash
fastener A made of metal or any other suitable material, which is formed in such
a manner that it can be screwed or otherwise fastened on to the inside of a window
sash C. being of sufficient length to stand out and turn over the sash bead B which
keeps the sash C. in its position, the portion which turns over the aforesaid bead
being of sufficient length to take a set screw D. I then provide a plate E of any
suitable size or shape, which is screwed or otherwise fastened on to the frame F
[Price Rdl

page_text: (being level with the inside of said bead) and which is furnished with a hole G.
not pierced through but of a sufficient depth and size to allow the point of set
screw D to enter the plate E on the aforesaid bead B which has been provided with
a facing of any ordinary draught excluder H such as rubber or felt, which comes
into contact with the sash C the set screw D is screwed against the aforesaid
plate E and in so doing the sash C is drawn forcibly towards the bead B firmly
pressing it against the draught excluder H thereby preventing any draught from
eutering and at the same time rendering it impossible to raise the sash C and
effectually preventing the sash from being shaken by wind or vibration. By
releasing the set screw D so that it becomes quite free of the plate E the window
can be raised in the ordinary manner.
This description applies to the lower sash, but the fastener can be applied in like
manner to the upper sash either inside or out.
The fastener can be used in like manner on casement windows and possesses this
distinct advantage, that the draught excluder being carried all round the bead it is
equally effective on the sill, which is not so in other existing fasteners.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
1 claim is
-
1. A sash fastener expressly constructed to draw a sash frame towards the bead
which runs round a window frame thereby pressing it tightly against a strip of
draught excluder.
