Improvements in connection with Window Sashes and Frames.
We, JAMES AVONDO TAYLOR and GEORGE APPLEBEE BROWN, both of 2, Weymouth
Terrace, Hertford Road, Lower Edmonton, Middlesex, Cycle Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
The object of this our invention is to entirely dispense with the use of cords and
weights for windows of buildings and also to supersede the usual appliances in use for
carriage windows and vehicles generally and which in the cases of windows of houses
and other buildings will render them absolutely secure against the attacks of burglars
or similar improper uses. The devices we employ are simple cheap and effective for
The sashes work freely in the grooves of
the purpose intended and are as follows.
the window frames in the ordinary way but instead of the usual cords pulleys and
weights we use one or more metal plates or discs of suitable size shape material and
thickness, preferably of steel which are affixed as follows. In any desired position on
the surface of each side of each frame we fasten one or more plates or discs by means
of screws placed at one end of each plate or disc the other end of the plate or disc is
loose and by the action of tightening or loosening of an adjusting or regulating screw
or screws the necessary springy action is given to the plates or discs.
The action is as follows. When the sashes of the windows are in position the
spring end of each plate or disc presses against the inner surface of the window frame
and gives the necessary rigidity so that each sash moves up and down easily and can
be stopped and stayed at any desired height. To prevent the window from being
improperly opened we pass a metal screw of suitable size made without the usual
flanged head through the sash frame in any desired position which bites the corre-
sponding surface of the window frame thus rendering it impossible to open it. By
the use of this invention the expense of pulleys weights and cords is avoided and our
plates and discs can be manufactured in quantities at a trifling cost. In order to give
greater strength to the plates or dises we may insert strips of metal of suitable size
and thickness beneath each plate or disc if found necessary.
For the better illustration of this our invention we have hereunto annexed draw-
ings in which
Fig. 1 shows the window in position with portions of the framework removed to
show the working of the invention. a, a, a, a, show the positions of the plates or
discs, b is the burglar proof screw.
Fig. 2 shows the window in position with portions of the framework removed to
show the working of our invention as applied to carriage windows. a, a, a, a, are the
plates or discs.

Fig. 4 is the same with the addition of the strengthening springs c, c.
Figs. 5 and 6 are two suitable shapes for the plates or discs d¹, d², being the
adjusting screws.
7 home a suitable shape for a plate or disc for carriage windows.

page_text: Having now particularly described and ascertained the nature of this our inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. The use and construction of spring plates or discs with or without the addi-
tional strengthening springs and
2nd. The use of a screw or screws for safety purposes as substantially here set forth
described and illustrated...
