PROVISIONAL SPECIFICATION.
Improvements in Window Sashes and Frames and the like.
I JASPER GIBSON of No. 51 Lincolns Inn Fields in the County of Middlesex
Solicitor do hereby declare the nature of this invention to be as follows: -
This invention relates to a new and improved mode of fitting window sashes
and frames (and other appliances which are moved up and down in a similar
manner to window sashes) and the objects of my invention are (1) to prevent
window sashes and the like from becoming loose and shaky in dry or windy
weather (2) to prevent window sashes and the like becoming tight and jamming in
damp weather and (3) to prevent draughts between window sashes (and the like)
and the frames.
The manner in which I effect these results are as follows-I do not allow the
wood of the sash to come into contact with the wood of the window frame and I
so arrange matters by means of a metal flange attached to the sash working in a
metal groove attached to the frame that the sash works up and down by metal
working against metal. The metal groove should preferably be made of two
sufficient lengths of angle metal screwed or attached to the sash frame so as to
leave sufficient space for the flange on the sash to work between and the flange on
the sash may consist of a sufficient length of T or angle metal screwed or attached
to the.sash.
-
The woodwork of new sashes should be so constructed as to admit of a space
between the sash and the frame sufficient to accommodate the flange and groove
and the woodwork of the sash will not touch the woodwork of the frame.
Old sashes may easily be partially planed down and adapted to the above
conditions.
The open space between the sash and the frame may be hidden from sight when
the sash is fitted by a sufficiently prominent "parting bead" in the case of the
outside or upper sash and by a sufficiently prominent outside sash bead in the case
of the inside or lower sash.
In order that the usual sash line arrangements may not be interfered with by
the adoption of my invention one half (in depth) only of the sash need be cut away
and the sash line can be fixed to and work from the half which is not cut away or
the whole may be cut away and if necessary a metal plate with a fixed ring or eye
may be attached to the upper part of the sash at either end thereof so that such
ring or eye may project over and receive the sash line which may be suitably
secured on the under side of the ring or eye.

COMPLETE SPECIFICATION.
Improvements in Window Sashes and Frames and the like.
I, JASPER GIBSON of No. 51, Lincolns Inn Fields in the County of Middlesex,
Solicitor 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, that is to say :-
This invention relates to a new and improved mode of fitting window sashes
and frames (and other appliances which are moved up and down in a similar manner
to window sashes) and the objects of my invention are (1) to prevent window
sashes and the like from becoming loose and shaky in dry or windy weather;

page_text: (2) to prevent window sashes and the like becoming tight and jamming in damp
weather and (3) to prevent draughts between window sashes (and the like) and the
sash frames.
The manner in which I effect these results is as follows: I do not allow the
wood styles of the sash to come into contact with the sash frame and I so arrange
and effect this by means of a metal flange attached to the sash which will engage
with and work in a metal groove attached to the sash frame thus providing metal
guides (metal against metal).
The metal groove upon the sash frame should preferably be made of two
sufficient lengths of angle metal screwed or attached to the pulley style of the sash
frame by one member of each of the angle metals so leaving the other members of
the angle metals standing out, with a space left between same in which space (or
groove) so left will be received the flange of the angle metal piece attached to the
style of the sash. The said flange on the sash may consist of a sufficient length of
Tmetal or as before stated of angle metal the outstanding flange in either case
being the running feather of the side frame groove.
It may be remarked that as an alternative mode of arranging this fitting the
outstanding flange or feather might be attached to the pulley style of the sash-
frame and the groove be arranged on the sash style.
The woodwork of new sashes should be so constructed as to admit of a space
between the sash and the sash frame styles sufficient to accomodate the outstanding
metal flange and the groove and the woodwork of the sash will consequently not
touch the woodwork of the frame.
Old sashes may easily be planed or otherwise cut down so as to leave sufficient
space between the woodwork for the reception and fixing of the metal guide feather
and the groove therefor.
The open space between the sash and the frames may be hidden from sight when
the sashes are fitted by a sufficiently prominent parting bead and facing bead
respectively for the upper and lower sashes.
In order that the usual sash lines and fittings may not be interfered with by the
adaption or adoption of my invention one half (in depth) only of the sashes need
be cut away, except to such an extent as to prevent the styles of the sash coming
in contact with the pulley styles of the sash frames, and the sash line can be fixed
to and work from the half which is not cut away or the whole may be cut away and
if necessary a metal plate with a fixed ring or eye may be attached to the upper
part of the sashes at either side thereof so that such rings or eyes may project over
and receive the sash line which may be suitably secured thereto and be run over
the ordinary pulley of the pulley style to the sash weights in ordinary manner.
In new windows the necessity of a parting bead is avoided.
In order that the said invention may be readily understood I have hereunto
annexed a sheet of drawings illustrative thereof and have referred thereto by
figures and letters of reference in the following more particular description
thereof.
Fig. 1 represents in horizontal sectional plan a sash frame and inside and outside
sashes fitted according to this invention.
Fig. 2 is a partial elevation of like construction with portions broken away to
exhibit details of parts.
The feather of the sashes engaging with the grooves is shown as an angle
metal piece and the grooves are made of two like angle metal pieces so that the
second of the angle metal pieces may be fastened by screws after the other parts
are arranged in position so, securing the whole when the last angle metal piece is
finally secured in position. After this a facing bead may be nailed or screwed on
to give a clean finish.
Referring to the drawings A is the sash frame, A' is the facing bead B the

Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:
The improvements in window sashes and frames and the like having the metal
flanges or feathers a and the metal grooves or guides formed conveniently of
angle metal pieces constructed and operating substantially as and for the purpose
herein described in reference to, and shewn by the accompanying drawings.
