PROVISIONAL SPECIFICATION.
Improvements in or connected with Window Sashes, Doors, and
the like.
I, LAURANCE SEAGER, of Sittingbourne, in the County of Kent, Builder and
Contractor, do hereby declare the nature of this invention to be as follows:-
My invention relates to sliding and casement sashes to doors and the like and has
for its object to prevent them from rattling and to render them dust and draught
proof.
When my invention is applied to a sliding sash one of the sash styles is grooved
and the adjacent pulley style is also grooved, the two grooves being adapted to
receive a pair of wedges, one of which has a sash cord connected to it and is
connected to the sash in such a manner that it cannot move longitudinally relative
thereto but so that it has a slight lateral movement. The other wedge which is
arranged between the first mentioned wedge and the window sash is capable of a
slight longitudinal movement relative to the latter and means are provided such for
instance as a lever for effecting such longitudinal movement.
With this arrangement it is obvious that after the sash has been opened or closed,
the movement of the last mentioned wedge presses the first mentioned wedge tightly
against the pulley style and so prevents the rattling of the sash and forms a tight
joint.
If desired corresponding wedges may be arranged in the other sides of the
gash.
I sometimes fix to the pulley style and to the adjacent wedge, corrugated plates
or surfaces which when in contact serve to prevent the sash from being raised or
lowered. Springs or the like are provided for normally holding one plate out of
contact with the other. The inner part of the sash style can be made detachable to
facilitate the putting in of new sash cords.
Some of the advantages of my invention are that when the wedges are removed
the sashes can be taken out of their frames for cleaning or repairing, that the inside
and outside beads may be dispensed with so that the frame need only be of the
width of the two sashes, and that heavy windows may be moved with much greater
ease than when arranged in the ordinary manner.
When my invention is applied to casement sashes and to doors the wedges are
arranged in grooves around the same.

COMPLETE SPECIFICATION.
Improvements in or connected with Window Sashes, Doors, and
the like.
I, LAURANCE SEAGER, of Sittingbourne, in the County of Kent, Builder and
Contractor, do hereby declare the nature of this invention and in what manner the
sarbe is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention relates to sliding and casement sashes, to doors and the like and
has for its object to prevent them from rattling and to render them dust and
alrust's

page_text: When my invention is applied to a sliding sash one of the sash styles is grooved
and the adjacent pulley style is also grooved, the two grooves being adapted to
receive a bar to which a sash cord is connected and which is detachably secured to
the sash in such a manner that it cannot move longitudinally relatively thereto but
so that it has a slight lateral movement.
In this bar are formed inclined planes and upon another bar are wedges arranged
between the first mentioned bar and the window sash and capable of a slight
longitudinal movement relatively to the latter, means being provided such for
instance as a lever for effecting such longitudinal movement of the bar having the
wedges.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which,
Figure 1 is a sectional elevation of one side of a window frame with sliding sashes
having my improvements applied thereto.
Figure 2 is a section on the line r, a drawn to an enlarged scale.
Figures 3 to 6 are views drawn to the same scale as Figure 2 and hereinafter
described.
As the method of applying my invention to both the upper and lower sashes of a
window is practically identical I will describe my invention as applied to one sash
only it being understood that the same letters of reference indicate corresponding
parts in both sashes.
a is the sash frame, the pulley style thereof and the sash sliding in the
frame a; d is the bar to which the sash cord d¹ is connected, the said bar being
arranged so that it is partly located in a groove in the pulley style 6 and partly in
a groove in the sash e as shown most clearly in Figure 2 and being provided with
two inclined planes e, e; f, f are the wedges which act in conjunction with the
inclined planes e, e these wedges being connected to a metal bar or plate g so that
the movement of the said wedges will take place simultaneously.
h is a bolt which is attached to the top of the sash c and serves to prevent the
bar d from moving longitudinally relatively to the said sash. i is a lever pivotted
at to the sash and engaging at one end with a hole in the bar or plate g whilst the
other end serves as the handle.
With this arrangement it will be understood that when the lever i is moved by
pulling it downwards from the position shewn in the drawing the plate g will be
operated to move the wedges f, f so that they bear against the corresponding
inclined planes e, e whereby the bar d will be caused to press tightly against, the
back of the groove in the pulley style and the bar g against the back of the groove
in the sash thereby preventing the rattling of the said sash.
In order to provide for leaving a window open to a certain extent and ensuring
that it shall not be further opened from the outside I sometimes arrange in con-
nection with my wedges a locking device.
As shown in the drawing this locking device consists of a bar ; secured to the
pulley style 6 at the back of the groove therein as shown in Figures 1 and 2 and
provided with ratchet teeth (as shown in Figures 3 and 4 which are a side and
front elevation of the said bar) and of a block 4 (shewn in side and front elevation
at Figures 5 and 6) having teeth designed to engage with the teeth of the bar j, a
spring being attached to the block k for normally holding the teeth of the block
out of engagement with the teeth of the bar j. This block k is located in a recess
formed in the bar d at the back of one of the inclined planes e thereof as shown in
Figure 1.
With this arrangement it will be understood that the sash having been placed in
the required position the movement of the wedges first acts upon the block k to force
the teeth thereof into engagement with the teeth of the bar and then tightens the
bars d and g in the manner herein before described.
If desired the arrangement of mechanism hereinbefore described may be used in
conjunction with both sides of a ɛash but in practice I find that the arrangement on
one side of the sash is sufficient. In this case the opposite side of the sash is guided

page_text: in the sash frame by means of a plain bar d arranged as herein before described but
without the inclined planes..
When it is desired to remove a sash having my invention applied thereto from the
sash frame it is only necessary to disconnect the bars d, d from the sash so that the
said bars can be drawn out of the grooves therein when the sash is free and can be
pulled out of the frame.
Another advantage of my invention is that the inside and outside beads may be
dispensed with so that the frame need only be of the width of the two sashes.
g
When my invention is applied to casement sashes and to doors the bars d and
with the wedges are arranged in a groove upon the edge of such casement sash or
door the movement of the wedges serving to project the bar d sufficiently out of the
groove to make contact with the frame of such sash or door.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) The improvements connected with sliding sashes, casement sashes, doors and
the like consisting in the combination therewith of two bars having inclined surfaces
and so arranged that one can be moved longitudinally relatively to the other sub-
stantially as described.
(2.) The combination with a sliding sash of two bars having inclined surfaces and
located partly in a groove in the sash frame and partly in a groove in the sash, one
of the said bars being adapted to be moved longitudinally relatively to the other,
substantially as described.
(3.) The combination with a sliding sash provided with two bars having inclined
surfaces and designed to be moved longitudinally relatively to each other in the
manner referred to in the preceding claiming clause, of means for locking the said
sash substantially as described and illustrated in the accompanying drawing for the
purpose specified.
