Improvements in and Connected with Window Sashes and
their Frames.
We, JAMES LOUGHRAN, and FRANCIS LOUGHRAN both of 70 High Street, in the
town and County of Lanark, Joiners, do hereby declare the nature of this Invention,
to be as follows:-
The purpose of our Invention is, the making of window sashes portable, and easily
removed from their frames and cases to the inside of the house, so as to facilitate the
cleaning, glazing, painting and repairing of them, without going outside the windows,
and so prevent accidents to persons employed at this kind of work.
Our improvements have reference to that class of windows with two sushes hung
with weights, cords, chains, or ribbon-wire (hereinafter termed cord) the upper sash
sliding outside the under sash, having parting heads between them. And the nature
and novelty of the improvements consist all as follows:-In passing the end of each
cord through a small plate or other equivalent catch, and securing the end under the
plate by a knot or otherwise, and in inserting this plate in angled grooves or slits
formed in the sides of a channel shaped bush, or griper, sunk and screwed into the
edge grooves of the sash, the angle of the groove and the weight of the sash tending
to keep the plate and cord secure and in proper position; and yet allow of the easy
removal of the plate and cord from its holding bush, or griper, and its sash which can
then be lifted out from the window case. A further improvement consists in
elongating the pocket-holes in the pulley styles to six or eight inches above the lower
sash, and in making the pocket-holes wide enough to secure the parting bead on to the
pocket piece or cover of the pocket-hole, and half checking the joint on the outside of
the bead to prevent the admission of air or water and cutting the parting beads at the
end of the pockets so that they are removed with the cover. The upper end of each
cover has an iron plate screwed on the inside with a slot in it, for taking on to a hook
catch on the inner end of a square stud fitted in a corresponding hole cut in the style.
above the pocket-hole. A plate is screwed on the face of the style, opposite the stud,
with a sunk headed screw screwed into the stud for tightening it up after the inner
plate of the cover has been hooked on, or slacking the screw and pushing in the

removed. The lower sash is now free to be pushed in, through the pocket-hole, into
the recess at either side, for the removal of the ends of the cords and securing plates
from their griping bushes, when the sash can then be removed inwards clear of the
batten rods, which under these improvements are fixed. The upper sash can now be
brought down in line with the open pocket-holes and have its cords removed in the
same manner as the lower sash, and brought in past the batten rods. Each cord as
removed would be carefully placed in a griping catch or rack secured to the inside
facing or batten rod, convenient to the hand for replacement when putting in the
sashes. This catch might consist of a simple hinged plate screwed to the facing near
the batten rod on each side, having two recesses in cach, for the cords of the upper and
lower sash, which when folded up would firmly hold the cords, but when not in use
would be folded down out of the way of venetian or other blinds. In replacing the
sashes the converse operation would be performed, that is, the upper sash would first
be inserted and its cords refixed, when it could be pushed out past the parting beads
in line with its pulleys; and then the lower sash would be replaced, having its cords
secured in like imanner, after which the pocket covers would be hooked on to their
catches and drawn back tight into their proper position, by the screws and studs
above.

Improvements in and Connected with Window Sashes and
their Frames.
We, JAMES LOUGHRAN, and FRANCIS LOUGHRAN, both of 70 High Street, in the
town and County of Lanark, Joiners, do hereby declare the nature of our invention
and in what manner the same is to be performed and ascertained in and by the
following statement in writing, reference being had to the accompanying sheet of
Drawings, and to the letters and figures marked thereon, that is to say :-
The purpose of our Invention is; the making of window sashes portable, and easily
removed from their frames and cases to the inside of the house, so as to facilitate the
cleaning, glazing, painting and repairing of them, without going outside the windows,
and so prevent accidents to persons employed at this kind of work.
Our improvements have reference to that class of windows with two sashes, hung
with weights, cords, chains or ribbon-wire (hereinafter termed cord) the upper sash
sliding outside the under sash, having parting beads between them.
And in order that our said invention, and the manner of performing or carrying the
same into effect or practice may be properly understood, we have hereunto appended
a sheet of explanatory Drawings, in which the same reference letters are used to
indicate corresponding parts in all the Figures where shown.
Figure 1, is a front elevation partly in section, looking from the inside of the house
or apartment, of a window, or window sashes A, A', and their fixed frames B, B', and
fittings, to which our improved.devices have been applied for enabling the sashes to
be easily removed from their frames for cleaning the glass, or other purposes, and
replaced again. Figure 2, is a corresponding sectional plan showing the inner lower
sash A, as being removed from its retaining frame and casing to the inside of the
house. While Figure 3 is a corresponding side or edge sectional elevation of the
frame B, B of the window with the sashes A A', removed to show the sliding grooves
B3, and retaining and parting beads and batton rods C, C1, C2. Figure 4 is a side and
edge view respectively to an enlarged scale of the retaining plate D of our improved
removable pocket pieces b, b, or covers of pocket holes in the grooves B2, B3, of the
pulley styles B, B, of the fixed frame. Figure 5 is a section and end view respectively.
to an enlarged scale of the screw retaining catch D1, D2, for securing the plates D, D
and their pocket pieces b, b. Figure 6, represents a side elevation of a simple square
pointed Key E used for turning the screw d for relieving and locking the catch D'
shown in Figure 5. Figure 7, is a side view and edge section respectively of a
metallic bush F, with angled removable plate F', and hole in it for securing the
Knot a' at the lower end of the window cords a; this bush being sunk in the edges
of each window frame at the bottom of the grooves a², of the window cords a.
Figure 8, is a front and edge view respectively of a hinged plate retaining catch
G, G', for receiving and retaining the portable plate F¹ and the Knots of the sash
cords a on each side while removing the sashes A, A' from their frames.
Figure 9, is a front and end view respectively of a finger plate H for being attached
to the lower end of the removable pocket covers b, b, for ease in removing and
replacing them by.
And

page_text: Referring to these Drawings:-The nature and novelty of our improvements consist
all as follows: In passing the end of each cord a through a small plate F¹ or other
equivalent catch, and securing the ends under the plate by a Knot a¹ or otherwise, and
in inserting this plate Fin angled grooves or slits formed in the sides of a channel
shaped bush, or griper F, sunk and screwed into the edge grooves of the sash A, the
angle of the groove and the weight of the sash tending to keep the plate F and cord a
secure and in proper position as seen in Figures 1 and 7 of the Drawings; and yet
allow of the easy removal of the plate F¹, and lower end a¹ of the cord a from its
holding bush, or griper F, and its sash A or A, which can then be lifted out from the
window case B, B₁, the plate F1 and end of the cord a¹ being inserted into the
retaining plate G¹ screwed on the batten rod C² convenient for that purpose at C³. A
further improvement consists in elongating the usual pocket-holes of one or both
sides of the race parts B2, 6 of the front sash A of the pulley styles B to six or eight
inches above this lower sash A; and in making the pocket-holes b¹ wide enough to
secure the parting bead C¹ on to the pocket-piece or cover b, of the pocket-holes b'
and half check the joint on the outside of the bead to prevent the admission of air
or water, and cutting the parting beads C at the ends of the pockets so that they
are removed with the cover b. The upper end of each cover.b, b, is bevelled inwards
and has an iron retaining plate D secured on its inside, with a slot 2 in it, for taking
on to a hook catch d' on the inner end of a square stud D2, working in the bush D',
which is fitted in a corresponding hole cut in the race parts B2, of the style B above
the pocket-holes. This bush D is screwed on the face of the styles B, opposite the
stud D, with a sunk headed screw d screwed into the stud D³, actuated by the Key E
for tightening it up after the slot d² of the inner plate D of the cover has been hooked
on to the catch d', or slacking the screw d and pushing in the stud D², d¹ and upper
end of cover b to enable this to be raised and pushed into or removed from the recess
Bs of the window frames, in which the weights W of the cords a work. The front
lower sash A is now free to be pushed in through the pocket-hole b¹ into the recess B³
at either side, for the removal of the ends of the cords a and securing plates F' from
their griping bushes F, when the sash A can then be removed inwards clear of the
batton-rods C, which under our improvements are fixed, as particularly seen in the
act of being removed in Figure 2. The upper outer sash A¹ can now be brought
down in line with the open pocket-holes & and have its cords a removed in the same
manner as the lower sash A, and brought in past the batten rods C. Each cord a as
removed would be carefully placed in a griping catch or rack G, G¹, secured to the
inside facing or batten rod, C² at C³, convenient to the hand for replacement when
putting in the sashes A, A'. This catch would preferably consist of a simple hinged
plate &, G screwed at C3 on the face of or near the batten rod C on cach side, having
two recesses y in each hinged part G₁ for the cords a of the upper and lower sashes A¹, A,
which when folded up would firmly hold the cords a, but when not in use would
be folded down out of the way, of venetian and other blinds, all used and constructed
as shown in Figures 3 and 8, at C³. One cord a of the window sashes A, A¹, being
thus removed, either of the sashes may be turned into the house on the other cord, for
cleaning the outside of the window, or both cords may be removed and the window
lifted in and cleaned, and replaced with the cords in it. In replacing the sashes A, A¹,
the converse operation would be performed, that is, the upper sash A' would first be
inserted and its cords a refixed by replacing the plates F in their bushes F, when it
could be pushed out past the parting laths or beads C in line with its pulleys w; and
then the lower sash A would be replaced, having its cords a secured in like manner,
after which the pocket covers b, b would he hooked on by their slots d to their catches d¹
and drawn back tight into their proper position to fill the pocket-holes by the
Key E and screws d and studs D, d'above. The lower ends 62 of the covers b, on
opposite sides are so formed of a V or checked shape, into the style B that they cannot
be removed without lifting out and removing the upper end and its retaining plate D
off the catch d¹ of the stud D2. Instead of making the angled plate F¹ for securing
the Knot end of the cord a, portable or removable; it might be made as a fixture
slotted plate F,, either secured in the bush F, or simply driven tight into a narrow

page_text: angled groove or mortice, formed for it in the edge wood of the sash near the bottom
of the groove a² of the cord a, as shown in side and horizontal section in Figure 8 A.
A groove or slot 1 is formed in the angled plate F¹ for the insertion and removal of
the end of the cord and Knot a a¹, from the side of the sash; the Knot and cord
would always be held tight under the angled slotted plate unless when pulled out with
force from the side of sash after its removal all as before described and shown in
section and end view Figure 7 A.
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 :-
First. The construction, or arrangement and combination of the improved devices
and fittings of window sashes and their frames, all substantially as, and for the
purposes and advantages herein described, in reference to and shown in the
accompanying Drawing.
Second. The fitting of removable covers or doors over or in elongated pocket-holes,
in one or both sides or styles of window frames right into the weight recesses sufficient
for the lateral movement and removal of the window-sashes, substantially as herein
described, in reference to and shown in the accompanying Drawings.
Third. The use of a retaining plate and screw or equivalent catch for retaining the
removable doors in the styles of window frames, all substantially as herein described
in reference to and shown in the accompanying Drawings.
Fourth. The application and use of removable or fixed angled plates for retaining
the ends of the cords in the edges and grooves of the window sashes, substantially
as herein described in reference to and shown in the accompanying Drawings.
