PROVISIONAL SPECIFICATION.
Improvements in Window Fastenings.
I EDWARD JAMES BEAUMONT of 38 College Road Reading Berkshire Clerk
do hereby declare the nature of this invention to be as follows:-
My invention relates to the construction of fastenings for sliding window sashes.
The fastening is made with parts to attach to the outer sliding sash and to the inner
sash or to the inside bead or to this bead and the lining together. In most cases that
part of the fastening which is attached to the vertical member of the outer sash is
also attached to the meeting rail of that sash. To the part of the fastening.so
attached is pivoted a piece which carries a thumb screw which takes into and
screws up against the piece which is fixed to the meeting rail of the inner
sash or to the inside bead." In one or both of the fastenings when two are used this
pivoted piece moves upon a long pin, staple, or bar so that the outer sash or either or
both sashes may be opened through a limited adjustable range so as to permit the
passage of air between the meeting rails or above or below the two sashes
respectively. In any position within the range mentioned the sashes may be firmly
fixed by the fasteners so that they cannot be opened from outside; so that they
are held firmly together and to the parting bead and frame and cannot rattle; can
always be fastened at the sides when blinds are down, and will permit the windows
to be tightly closed against dust & draughts.

COMPLETE SPECIFICATION.
Improvements in Window Fastenings.
EDWARD JAMES BEAUMONT 38 College Road Reading Commercial Clerk 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 the construction of fastenings for sliding window sashes.
The fastening is made with parts to attach to the outer sliding sash & to the inner
sush or to the inside bead or this bead & the lining together. In most cases that
part of the fastening which is attached to the vertical member of the outer sash
is also attached to the meeting rail of that sash. To the part of the fastening so
attached is pivoted a piece which carries a thumbscrew which takes into & screws
up against the piece which is fixed to the meeting rail of the inner sash or to the
inside frame or bead. In one or both of the fastenings this pivoted piece moves
upon a long pin staple or bar, so that the outer sash may be opened through a
limited range, so as to permit the passage of air between the meeting rails, or
above the two sashes respectively. In any position within the range mentioned,
the sashes may be firmly fixed by the fasteners so that they cannot be opened from
the outside, and so that they are held firmly together to the parting bead & frame
& cannot rattle. They may also be fastened at the sides when the blinds are down
& will permit the windows to be tightly closed against dust & draughts.
My invention is illustrated by the drawings hereunto attached. Fig. 1 shows a
window with vertically sliding sashes, fitted with fastenings according to my
invention, and of the two forms chiefly described.
At the side L the simpler form of fastening is shown, as in position when the
[Pois Rd1

page_text: window is closed, and the fastener screwed up, pulling the two sashes together onto
the parting bead & to the frame.
The fastening of the lower sash is affected by the shoulder F of the screw C
being brought into contact with the jaw picce J, the frame work giving sufficiently
upon which the jaw J is fixed; to bring it in contact with the lower sash, which
securely fastens the same; at the same time as the upper sash is pulled forward by
the pressure put upon the pieces A or E Fig. 1. It is necessary that this should
be done, because if the fastening merely pulls the sashes together, the sashes are
still free to rattle in their frames, an objection which is overcome by my invention.
To loosen the fastening & to drop the window sash, fitted with this form of
fastener, the thumb screw C is loosened or unscrewed, and it may then be with the
piece B turned on the pivot of the latter which is fixed to the horizontal part of
the piece E. The shoulder F of the screw C is thus freed from the jaw J fixed to
the frame & may be turned round so as to lie upon the meeting rail of the upper
sash along by the glass. At the side K of the window Fig. 1 the piece B instead of
being attached to a short pivot as at the side L, shown also by Figs. 5 & 6, is
attached to a staple shaped piece or bar D which is fixed at its ends in the vertical
and horizontal parts of the piece A. The boss M of the piece B is free to slide
upon the staple D shown to a larger scale in Fig. 2, which shows the window as
closed & fastened. When it is desired to open the window as for ventilation the
thumbscrew C is slackened & the upper sash can then be lowered to the extent of
the length of the staple bar D above the boss M of the piece B, the sash with the
staple bar D passing downwards through the boss M. The window may then be
fastened as before by the thumbscrew C the fastening being as effective as when
the window is closed & the meeting rails brought together. If the staple piece D
Figs. 1, 2, 3 & 4 be say four inches in length from the top of the boss M then for
ventilation the upper sash may be lowered about four inches & the window still
fastened tightly as described.. In this case ventilation would be secured by the
& 6 are
openings at the top & between the sashes in the middle. In Figures
shown the construction to a larger scale of the parts of the simpler form of
fastener as shown at the side L. of the window Fig. 1. In Figs. 7 & 8 are shown
the jaw piece J used with either form of the fastener, the bottom of the jaw H
being countersunk as shown for the reception of the part F of the head of the
thumbscrew C. Instead of the countersink in the form shown a square edged
recess may be made & the shoulder F of the head of the thumbscrew may be of au
ordinary cheese shaped form. It is not necessary that the forms which I have
shown for the parts of the fastening should be precisely adhered to as it will be obvious
that the design may be varied in this respect while adhering strictly to that which
constitutes my invention. Although I have shown and described my invention as
preferably attached to the sides of the sashes & frames, it is obvious that by, a very
slight modification which any artizan would make it would be attachable to the
meeting rails in the centre of the window.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed 1 declare that what I
claim is :-
(i) A window fastening attachable preferably to the sides of the window sash or
sashes & frame substantially as herein described & shown.
(ii) In a window fastening attached to the sides of the sash or sashes & frame
the arrangement, construction, & combination of an angle basepiece A, with a
sliding pivoted piece B on the staple bar D and carrying a thumbscrew C engaging
in a jaw piece J attached to the side of a window frame for the purpose &
substantially as shown & described with reference to Figs. 1, 2, 3, 4, 7 and 8.
(iii) In a window fastening attached to the sides of the sash or sashes & frame
the arrangement & construction of parts by means of which the window sash or
sashes may be partly opened for ventilation or other purposes. & yet be firmly
fastened substantially as described with reference to Figs. 1, 2, 3, 4, 7 and 8.

page_text: (iv) In a window fastening attached to the sash or sashes and frame of a
sliding sash window, a basepiece E, pivoted piece B, thumbscrew C & jaw piece J,
substantially as described and shown with reference to Figs. 1, 5, 6, 7 and 8.
