We FRANCIS SANDERS MORRIS, of Middleton Lodge, Tottenham, in the county
of Middlesex Engineer and JOHN HENRY Fox, of Oakleigh, Broadwater Down,
Tunbridge Wells, in the county of Kent, Gentleman do hereby declare the nature
of this invention to be as follows:-
This invention relates to the construction of improved apparatus for securing
sliding sashes in any required position to which they may be raised or lowered and
for releasing the same when the sash is required to be raised or lowered.
In carrying out our invention we fix a rack or serrated bar in any suitable
position on the sash frame and to the door or window frame, we pivot a box or
case in which a pawl or tumbling piece is pivotted in such a manner as to
normally engage with the teeth of the said rack; the box or case is provided with
a projection which when the box or case is moved outwards on its pivot comes
against a swell or projection on the pawl and thereby disengages it from the teeth
of the rack.
When it is required to lower a sash provided with our improved apparatus it is
simply necessary to move the box or case outwards on its pivot by any suitable
means such as by a lug on its under side when the projection on or in the case or
box will come against the swell or projection on the pawl and will move it out of
engagement with the teeth of the rack and the sash will then fall by gravity; to
raise the sash it is lifted in the usual manner and the teeth of the rack will slide
over the pawl and when the sash has been raised to the required height it will be
securely held in position by the pawl engaging with the teeth of the rack.
Instead of placing a projection on the box or case we can fix it or a stop to the
door or window frame and in this case we can arrange the pivot of the pawl inde-
pendently from that of the box or case or one pivot can serve for both the pawl
and case and we form the pawl in two parts jointed together in such a manner
that one part can move upon the other part to a limited extent; the pawl rests
upon the said projection or stop and when it is required to lower the sash is
moved out of engagement with the teeth of the rack by moving the box or case
outwards on its pivot as hereinbefore described; when the sash is being raised the
lower part of the pawl is moved on its joint and then moving with the other part
allows the rack to pass; as soon as the sash is released a tooth of the rack bears

page_text: upon the end of the lower portion of the pawl which coming into contact with the
upper portion and resting on the projection or stop fixes the sash.
Or. the pawl can be arranged to hold in position a ratchet wheel the teeth of
which engage with those of the rack and support the sash in a similar manner to
the pawls herein before described. In this case however the box or case would not
require to be pivotted and the pawl would be operated by a push-piece projecting
outside the box or case.
Or the pawl working direct in the rack can be pivotted to a spring rod working
in and projecting through a slot in the box or case, so that by moving the said
spring rod the pawl can be moved out of engagement with the teeth of the rack; a
suitable stop or its equivalent is provided to support the pawl.
Instead of employing a rack and pawl we can effect a similar object to that
hereinbefore described by fixing within the box or case a rod or spindle part of
which is round and part of which is square in cross section; on the round part of
the rod or spindle we place a collar or barrel having a curved or cam-shaped face
and provided with a knob or the like projecting outside the box or case and
working in a slot therein; on the square part of the rod or spindle we mount a
sleeve so that it can slide thereon; one end of the said sliding sleeve when the
collar or barrel is rotated bears against the cam-shaped face of the collar or barrel
and is formed with a correspondingly curved or cam-shaped face and the other end
of the sleeve bears against the face of the sliding sash. When the cam shaped
faces of the collar or barrel and sleeve respectively coincide the sash is free to be
lifted or lowered; when however the collar or barrel is rotated by means of its
knob the cam shaped face thereof bearing against the face of the sleeve will force
the latter against the face of the sash and will thereby hold it securely in any
position into which it may be raised or lowered.
Or the sash can be secured by means of a number of arms or levers contained
within the top rail of the sash and jointed to each other in such a manner that
they can be expanded laterally by means of a spring or its equivalent so as to
force a pair of horizontal arms or rods to bear against serrations or teeth on the
edges of the door or window frame and thereby hold the sash in position; a lug
such as is usually provided for raising and lowering carriage windows is fixed to a
plate projecting slightly above the top of the sash and capable of sliding up and
down on the sash frame; the said plate is adapted to operate the said levers or
arins so as to contract them when the plate is raised or depressed to lift or push
down the sash thereby overcoming the pressure of the spring and withdrawing the
horizontal arms from contact with the serrated edges of the door or window frame.

page_text: We FRANCIS SANDERS MORRIS of Middleton Lodge Tottenham, in the County
of Middlesex, Engineer, and JOHN HENRY Fox of Oakleigh, Broadwater Down
Tunbridge Wells in the County of Kent Captain, do hereby declare the nature of
our invention for "IMPROVEMENTS IN APPARATUS FOR SECURING SLIDING SASHES"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
This Invention relates to the construction of improved apparatus for securing
sliding sashes in any required position to which they may be raised or lowered and
for releasing the same when the sash is required to be raised or lowered.
In carrying out our Invention we fix a rack or serrated bar in any suitable
position on the sash frame and to the door or window frame we pivot a box or case
in which a pawl or tumbling piece is pivotted in such a manner as to normally
engage with the teeth of the said rack; the box or case is provided with a
projection which when the box or case is moved outwards on its pivot comes
against a swell or projection on the pawl and thereby disengages it from the teeth
of the rack.
When it is required to lower a sash provided with our improved apparatus it is
simply necessary to move the box or case outwards on its pivot by any suitable
means such as by a lug on its under side when the projection on or in the case or
box will come against the swell or projection on the pawl and will move it out of
engagement with the teeth of the rack and the sash will then fall by gravity; to
raise the sash it is lifted in the usual manner and the teeth of the rack will alide
over the pawl and when the sash has been raised to the required height it will be
securely held in position by the pawl engaging with the teeth of the rack.
Instead of placing a projection on the box or case we can fix it or a stop to the
door or window frame and in this case we can arrange the pivot of the pawl
independently from that of the box or case or one pivot can serve for both the
pawl and case and we form the pawl in two parts jointed together in such a manner
that one part can move upon the other part to a limited extent; the pawl rests
upon the said projection or stop and when it is required to lower the sash is moved
out of engagement with the teeth of the rack by moving the box or case outwards
on its pivot as hereinbefore described; when the sash is being raised the lower part
of the pawl is moved on its joint and then moving with the other part allows the
rack to pass; as soon as the sash is released a tooth of the rack bears upon the end
of the lower portion of the pawl which coming into contact with the upper portion
and resting on the projection or stop fixes the sash.
Or the pawl can be arranged to hold in position a ratchet wheel the teeth of
which engage with those of the rack and support the sash in a similar manner to
the pawls herein before described.
. In this case however the box or case would not require to be pivotted and the
pawl would be operated by a push-piece projecting outside the box or case.
Or the pawl working direct in the rack can be pivotted to a spring-bar working
in and projecting through a slot in the box or case, so that by moving the said
spring-bar the pawl can be moved out of engagement with the teeth of the rack,
a suitable stop or its equivalent is provided to support the pawl,

herein before described by fixing within the box or case a rod or spindle part of
which is round and part of which is square in cross section; on the round part of
the rod or spindle we place a collar or barrel having a curved or cam-shaped face
and provided with a knob or the like projecting outside the box or case and
working in a slot therein; on the square part of the rod or spindle we mount a

or barrel is rotated bears against the cam-shaped face of the collar or barrel and is
formed with a correspondingly curved or cam-shaped face and the other end of the
sleeve bears against the face of the sliding Bash. When the cam-shaped faces of
the collar or barrel and sleeve respectively coincide the sash is free to be lifted or
lowered; when however the collar or barrel is rotated by means of its knob the
cam-shaped face thereof bearing against the face of the sleeve will force the latter
against the face of the sash and will thereby hold it securely in any position into
which it may be raised or lowered.
Or the sash can be secured by means of a number of arms or levers contained
within the top rail of the sash and jointed to each other in such a manner that
they can be expanded laterally by means of a spring or its equivalent so as to force
a pair of horizontal arms or rods to bear against serrations or teeth on the edges of
the door or window frame and thereby hold the sash in position; a lug such as is
usually provided for raising and lowering carriage windows is fixed to a plate
projecting slightly above the top of the sash and capable of sliding up and down
on the sash frame; the said plate is adapted to operate the said levers or arms 80
as to contract them when the plate is raised or depressed to lift or put down the
sash thereby overcoming the pressure of the spring and withdrawing the horizontal
arins from contact with the serrated edges of the door or window frame.
In order to enable our Invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawings.
Similar letters in all the Figures represent corresponding parts.
Fig. (1) represents a vertical section of a part of a sash and frame to which our
Invention may be applied.
a. represents a pawl working on a pin c which is secured to the case 6; the case b
is free to move about d. and may be moved by the lug e.
It is clear that the sash f is held in position by the serrated bar g. 9 engaging
the pawl or tumbling-piece a.
To raise the sash it is lifted in the usual way by a lug on the top rail of sash, the
pawl or tumbling-piece a. is lifted by the inclined planes on the serrated bar 9. g.
and allows the sash to inove up.
To lower the sash it is simply necessary to release the pawl or tumbling-piece a.
from engagement with the serrated bar g. g by moving the case b outwards by
means of the lug e.
Fig. (2) represents a cross section on line A B of Fig. 1.
Fig. (3) is a front elevation of Fig. 1.
Fig. (4) is similar to Fig. (1) but having a pawl a. jointed at i to enabled the
serrated bar g. g to clear the pawl or tumbling-piece a. in a shorter radius.and to
make a more compact job than is the case in Fig. (1).
Fig. (5) represents a cross section on line CD of Fig. (4).

page_text: Fig. (10) is a modification of our Invention for effecting a similar object to that
hereinbefore described.
A box or case (b) let into the garnish rail or frame of the door carries a rod or
spindle (S S¹) part of which S is round and part of which S' is square in cross
section; on the rounded part S we place a collar (t) having a curved or cath-shaped
face and provided with a knob (t¹) or the like working in a slot in the box or
case (b); on the square part (S¹) we place a sleeve (u) so that it can slide thereon
one end of the said sliding sleeve when the collar is rotated bears against the cam-
shaped face of the collar (t) and is formed with a correspondingly curved or
cam-shaped face and the other end of the sleeve bears against the face of the
sliding sash. When the cam-shaped faces of the collar (t) and sleeve (u) respectively
coincide the sash is free to be lifted or lowered. When however the collar (t) is
rotated by means of its knob (t¹), the cam-shaped face thereof bearing against the
face of the sleeve (u) will force the latter against the sash and will thus hold it
securely in any position to which it may have been raised or lowered.
Fig. (11) is a cross section on J K of Fig. (10).
Fig. (12) is a front elevation of Fig. (10).
Fig. (13)-represents a vertical section through the top rail of a window sash
and frame; arins or levers (n. n) contained within the top rail of the sash and
jointed together. so that they can be expanded laterally by means of a spring (w)
or its equivalent so as to force a pair of horizontal rods (o. o.) to bear against
serrations (g. g.) on the edges of the door or window frame and thereby liold the
sash in position, a lug (p) (as is usually provided in raising and lowering carriage
windows) is fixed to a plate R free to slide up and down on the front of the sash,
the said plate is adapted to operate the said arms or levers (n. n) so as to contract
them when the plate is raised or depressed to lift or push down the sash thereby
overcoming the pressure of the spring and withdrawing the horizontal arins from
contact with the serrated edges of the door or window frame.
Fig. (14) is a cross section on L M of Fig. (13).
Fig. (15) is a vertical section in which the pawl or tumbling-piece a. is pivotted
to the disc (v), the disc (v) being fixed to the end of a rod or spindle (2) passing
along the front of the door; a handle or lever (y) is fitted to the spindle or rod (x)
near the centre of the door or window and weighted at one end so that by pushing
down the handle the disc (v) and spindle or rod a revolve slightly and the pawl or
tumbling-piece (a). is thereby disengaged from the serrations on the sash which is
free to fall.
To raise the sash it is raised in the usual manner, the paul or tumbling piece a,
being lifted and it slides over the serrations.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim is
1. Combining with sliding sashes of all kinds apparatus such as the boxes (b b)
carrying the pawls or tumbling-pieces (a a) in such a manner as to engage or
release sashes in any position, the said sashes carrying serrated bars or serrations
