Improvements in the Regulation and Fastening of Window Sashes
in their Frames.
JOIN CRAWFORD MOORE, Meads, Eastbourne, in the County of Sussex, Engineer,
hereby declare the nature of this invention to be as follows:-
This invention has for its object the dispensation of weights and improvements
in the regulation and fastening of window sashes in their frames, and to enable
them to-be turned inward for the purpose of cleaning.
In order to do this I make the sashes balance each other on cords or pullies or
a cord and pulley. I place a single pulley on the side of the bottom sash, a double
pulley on the frame about the top corner and above the single pulley. I then
place another double pulley on the top part of the frame, preferably about half
way across. I then place a single pulley on the top part of the top sash and under
the last double pulley about half way across. I then place a double pulley on the
frame in or near the other top corner, and another single pulley on the other side
of the bottom sash and under the last-mentioned double pulley. I then lace a
cord or band through all these pullies. I begin by putting it through the top
corner double pulley on the frame, then through the single pulley on the side of
the bottom sash, then another time, through the top corner double pulley on the
frame; then across to the double pulley on frame about half way across, then down
through the single pulley on the top part of the upper sash, then again up through
the double pulley on the frame directly above. Then across and through the other
double pulley in the top corner on the frame, then down to the single pulley on
the other side of the lower sash, then through the double pulley on frame on top
corner. Both ends of this cord may now be brought down to the desired position
for pulling and are made fast by self-acting fasteners either on the frame or sash,
so that in case the cords are let free they will hold them and not allow the sashes
to fall. By pulling an end of this cord the sashes can easily be regulated. A
spiral spring or springs will be placed on this cord to prevent slacking. The self-
acting cord retainer is a plate made fast on the sash or frame with lugs turned up
and a tongue or eccentric pivotted between in such a manner as to bind the cords
underneath so soon as they are released and become slack at the end.
In order to make fast these sashes I bore a hole in the frame about where they
meet and near to them. I then place a bolt in this hole with a flat side on it or it
may be an eccentric. This boit has a handle, on the end and between it and the
sashes a plate only which is ribbed next the latter. When the flat side of this bolt
is next the sashes they will be free to run up and down, but when it is turned a
little, the round or eccentric part will press the plate or plates tightly against the
sashes and lock them, these plates are pivotted to the frame. In order to turn
the sashes inside for the purpose of cleaning I bring them both to the bottom,
and remove pivot hinge or depress the lower part of the two inside beads, then

page_text: hook the sashes to the frame on one side and turn them inside. The pullies are
made for the cords to lift off, and the sashes are now supported by the hooks and
cords.

Improvements in the Regulation and Fastening of Window Sashes
in their Frames.
JOHN CRAWFORD MOORE, Meads, Eastbourne, in. the County. of Sussex, Engineer,
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:-
Reference being had to the accompanying drawings where like letters represent
like parts.
This invention has for its object the dispensation of weights as well as improve-
ments in the regulation and fastening of window sashes in their frames and to
enable them to be turned inward for the purpose of cleaning.
Fig. 1 is an inside elevation with both sashes closed.
Fig. 2 shows the parting bead out of position.
Fig. 3 shows the inside bead or flap.
Fig. 4 inside elevation of bottom sash opened inward with top sash in closed
position.
Fig. 5 is an inside elevation, bottom, sash removed with top sash down ready
hinged for opening inward.
Fig. 6 shows the eye which engages with the hook.
Fig. 7 the hook which engages with the eye.
Fig. 8 a side view of the cord grip and pulley on the lugs.
Fig. 9 is an end view of a part of both sashes, where they meet.
Fig. 10 is a side view of the lock.
Fig. 11 an end view showing the slot the plate slides in.
Fig. 12 an end view showing the excentric, and the manner in which the sashes
are engaged with the ribbed plates when locked.
Fig. 13 shows a second position of hooks and eyes.
It is usual to employ weights to balance sliding window sashes, but I now make
the sashes balance each other on a cord E and pulleys. Referring to Fig. 1 I place
a pulley D on the top part of the fixed frame, then another pulley C on the top
sash B nearly under it. I then place another pulley C on the other side of the top
sash, and another pulley 1 nearly directly above it. I then place another cord
grip and pulley P on the other side of A. By lacing a cord through P then
through D then through C and C then through D and through the other P, it
will be seen that the sashes balance each other over D and D made fast to the
fixed frame.
Any ordinary window sashes can be raised and lowered on the pulleys shown
in the annexed drawings. A position of these pulleys is shown in the drawings,
but I do not bind myself to any particular position, as for instance where there
is a window high up, and it is only necessary to lower the top sash for ventilation.
I should then fix the retainers or cord grips P on the wall or other fixed part below,
providing the fixed frame was too high.
To hinge these sashes, I place the hooks J Fig. 7 on the frame extending beyond
the beading R as shown in Figs. 1 and 5. I then place the eyes K Fig. 6 in the

page_text: position as shown in Figs. I and 5. Another way I fix these hooks and eyes so
that the bottom eye on each sash will not strike the hook above it, when the sash
is run to the top. This is shown on Fig. 13, the bottom hook and eye extend so
much further out from the beading R than the top hook and eye, so that the bottom
eye or hook will clear the top eye or hook, when the sashes are run to the top.
In this position the hooks and eyes can be placed nearer each other than shown in
Figs. 1 and 5. When they are placed directly under each other they have to be
as near the top and bottom of the sashes as possible to prevent the bottom hook
or eye from striking the top hook or eye when the sash is run up. Sometimes
I place the eyes K on the fixed frames and the hooks J on the sashes, in the
positions herein specified, hooks downward always within the width of parting
bead. To open the bottom sash inside for cleaning or other purposes, let the top
sash down to the bottom, release the cord from the retainer P, on opening side,
then turn down the hinged flap M Fig. 5, the hinges being marked M', withdraw
the flap or beading 7 Fig. 3 which is held in position by the studs S3, penetrating
the frame. The bottom sash will now open on its hinges inward as shown in
Fig. 4. To open the top sash, now down in position where the hooks and eyes
engage to form hinges, the same as the lower sash and about on a level with it;
the space S Fig. 4 will be opposite the dotted lines B¹ which are generally an
extension on the top sash B, the thickness of the beading S, the ends of which slide
up and down on the face of the beading, on each side, and support S beading in
its place. This space S¹ will permit of its complete removal by pulling it from out
of the fixed frame. The top sash B will now open up to the other sufficiently
inward for cleaning or other purposes. The dotted lines S Fig. 9 show the beading
and B the extension on B sash. As the sashes are closed the beading must be
returned to position. S2 Fig. 2 is a position of S removed to allow the lock to
operate: Fig. 8 is an enlarged view of the cord grip or retainer, marked P on
Figs. 1 and 4. f is the plate which is screwed to in position, t is the tongue and
excentric is the pivot on which the excentric turns, y is the lug or lugs turned
up on with the pulley and roller 7 and the excentric or tongue t rivetted or
pivotted between, i is a hole in the point of t where the cord E passes through,
the dotted lines in this figure show the position t and E take when the cord is
bound between the teeth on the excentric and the plate f, which when being
fixed must have the end uppermost, where the letter f is placed, Fig. 8. When
the excentric and tongue is up as shown in Fig. 8 the cord is released, but when
it is dropped as shown by the dotted lines, the cord is bound.
Fig. 10 is the lock which has a frame d, one end of which is rivetted in. F
shows the bearings one at each end of the excentric. C is a band round 6 fast on
the ribbed plate a, so that a will follow b. Fig. 11 shows the slot y in each end
of which a moves. Fig. 12 shows the manner in which the ribbed plate a engages
with the edge of the sashes A B. The position of F is shown in fixed frame
Fig. 4 which is made square for a key or handle to operate the lock with, C is
the band and 6 the excentric.
To fit the lock Fig. 10 in the frame, a hole or mortice is cut in it in a horizontal
position across the two meeting rails of sashes, the position of which is marked B¹
in Fig. 9. It is placed bodily in this hole with the ribs or grooves outward next
the sashes, the corner of the frame d being let in level with the face of fixed frame,
so that when locked the ribs a will only appear above the surface. This lock can
be packed at the back to make it engage tightly with the sashes as required. O
shows the sashes grooved or ribbed all the way up. To lower the top sash B pull
an end of E at about a right angle with itself as shown in Fig. 8, by gently
releasing this cord in this position B will fall. To raise B pull an end of E the
sash will run up and remain in any part of the run as soon as the ends are released
as the cordgrip then operates. To raise the bottom sash pull down E above P
with one hand, and with the other lift A to the desired position, then pull the end
of E below P until the slack is taken up. When the cord is released the grip
will hold it in position. By catching and operating a sash with the hand they

page_text: can both be raised or lowered together, without operating the grips. These sashes
can be locked in any position in their run and they can be turned inward for
cleaning and other purposes by placing them in position where the hooks and eyes
form hinges and by removing the beads. I do not confine myself rigidly to the
annexed drawings or forms of construction unless those herein specially claimed.
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:-
No. 1. The means of connecting sliding sash windows with their fixed frames
with one cord or band in their upward and downward movements and run for the
purpose of adjustment as described and illustrated.
No. 2. The means of balanceing and adjusting sliding sash windows on their
fixed frames on one cord or band in their vertical run as herein described and
illustrated for ventilation and other purposes.
No. 3. The construction and use of cordretainers or cordgrips as herein described
and illustrated, for the regulation and fastening of all window sashes requiring
a cord for that purpose.
No. 4. The position of all the rigidly and permanently fixed hooks and eyes
always forming the required hinges, simply by lowering the sashes to their engage-
ment, takes place, for the purpose herein set forth described and illustrated.
No. 5. The position, construction, and use of the lock Fig. 10, for the purpose
herein set forth and as described and illustrated.
No. 6. Ln sliding window sashes the combination of all the various parts of my
invention, for the purpose herein set forth, described and illustrated.
Dated this 10th day of January 1898.
