Improved Method of Constructing Window Sashes.
GEORGE GRAY Builder High Street Egham and CHARLES BATSTONE
Surveyor Grange Road Egham in County of Surrey 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:-
The object of our invention is to construct a simple and cheap method of releasing
eashes from the frames, for repairs and cleaning. The sashes are made less in width
between the pulley styles of frame, so as to allow the sashes to be moved to one side
sufficiently for the sash on the other side to swing clear of the outer and inner lining
& parting bead. By this means and a small notching of meeting rails, the sashes
can then be easily removed from the frame, and drawn to the inside of room
separately.
The sashes when in the frames are kept in their proper grooves by adjustable
metal screw guides.
The further object of this invention is to apply it to existing wood sashes, by
reducing the width of sashes & fitting same with the adjustable screw guides.
Besides the metal guides a continuous hard wood strip may be attached to the
face of guide and a continuous groove formed in the back edge of sash styles, this
wood strip may then be extended into the space between sash and pulley style or
withdrawn into the sash and allow sash to be moved out and regulated with the
adjustable screws.
In order that our invention may be better understood, reference is given to the
accompanying drawings Sheets No. 1 and No. 2 with letters and marks thereon.
Fig. 1 is a cross section of frame and sashes, showing space c required between
the pulley style d and styles of sashes b. b. also adjustable metal screw guide
plate.
This guide plate consists of slide d working in a guide plate e and then regulated
The
by screw, which screw is held in position in style of sash b. b by the plate n.
screw is used for extending the slide d into the space c of sash frame or to
withdraw it into the sash.
Fig. 2 is a part cross section of frame & sash showing the slides d withdrawn from
space c into the sashes b. b.
Fig. 3 is a plan of sashes and frame, showing method of releasing sashes, when
guides are withdrawn from the space c.
Fig. 4 is a side elevation of slide d.
Fig. 5 is a front elevation of plate e.
Fig. 6 is a front elevation of plate n.
Fig. 7 is a side elevation of the slide d with the addition of small metal friction
rollers for the purpose of fixing to large sashes.
Fig. 8 is a front elevation of slide d with addition of friction rollers.
Having given full description of our invention and manner in which it is to be
applied we declare that what we claim is-
1st. The construction of sashes in such a manner so as to be easily released from
the frame on the inside of room for the purpose of repairs and cleaning windows.

page_text: 2nd. The construction and application of metal adjustable guide plates for the
purpose of holding sashes in the proper position in the grooves of window frames.
3rd. For the application of the invention to existing windows.
