improvements in window Sashes and Frames.
I, EDMUND GEORGE KENDALL, of 53 High Street, Harborne, in the County
of Stafford, Architect, do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object improvements in window sashes and frames,
which will admit of the sashes being reversed for the purpose of cleaning and
ventilation and is very easily applied to existing windows and old sashes without
much alteration. This invention is a further development or improvement upon
my previous Patent No. 13810 A.D. 1894.
According to my present invention I make the dovetail piece of U section that
is to say, the base of the dovetail piece has two wings turned up at an outward
angle therefrom by rolling or pressing or casting. This dovetail piece is used just
the reverse of the one in my previous Patent, the present one being screwed upon
the pulley style and the recess is formed in the sliding portion of the sash or the
supplemental piece placed upon the sash. This leaves a hollow or recess in which
the sash cord comfortably works. A supplemental cross bar or piece is screwed
upon the sash which forms a suitable abutment for the knot or fastening of the
sash cord.

COMPLETE SPECIFICATION.
Improvements in Window Sashes and Frames.
I, EDMUND GEORGE KENDALL of 53 High Street, Harborne, Birmingham in
the County of Warwick, Architect, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention has for its object improvements in window sashes and frames
which will admit of the sashes being reversed for the purpose of cleaning and
ventilation and is very easily applied to existing windows and old sashes without
much alteration. This invention is a further development or improvement upon
my previous Patent 13810 A.D. 1894.
According to my present invention I make the dovetail piece of U section, that
is to say the base of the dovetail piece has two wings turned up at an outward
angle therefrom by rolling or pressing or casting. This dovetail piece is used just
the reverse of the one in my previous Patent the present one being screwed upon
the pulley style and the recess is formed in the sliding portion of the sash or the
supplemental piece placed upon the sash. This leaves a hollow or recess in which
the sash cord comfortably works. A supplemental cross bar or piece is screwed
upon the sash which forms suitable abutment for the knot or fastening of the
sash cord.

page_text: In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated the same and in doing so I have retained the letters
of reference which apply to similar portions in my previous Specification herein
before mentioned.
Figure 1. is a sectional plan through the side frame showing one sash open upon
its pivot and the other closed as in Figure 2 of the Specification of my former
Patent.
Figure 2. is a vertical part section and part elevation through the frame.
Figure 3. is a perspective view of the metal channel dovetail piece S.
According to this invention I am able to dispense altogether with the extra
pulley style D shown in my former Specification No. 13810 A.D. 1894. In doing
this I form the dovetail piece S from metal with the dovetail wings or flanges s'
and which when mounted as shown in the dovetail recess in the sash B leaves a
space or box in which the cord N is free and safe to work without any obstruction.
I secure the end of the cord N to the small bracket M which has a projection m¹
through which the cord N passes and under which the knot n¹ is formed. I thus
attain greater compactness by this supplimental invention as well as increased
tightness as the metal dovetail piece is not liable to objectional contraction and by
these means existing windows may be more easily adapted to my invention.
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 I
claim is
The improvements in window sashes and frames having the metal or other
equivalent dovetail pieces S working in the sash frame B either with or without
the bracket M substantially as and for the purpose berein set forth and shown
upon the accompanying drawings.
Dated this 17th day of February 1896.
