Year: 1880

page_text: LETTERS PATENT to James Hayes, junior, of 18, Hermes Street, Pentonville,
in the County of Middlesox, for an Invention of "IMPROVED MEANS FOR
FACILITATING THE REMOVAL OF WINDOW SASHES FOR THE PURPOSE OF
CLEANING AND REPAIRING THE SAME."
PROVISIONAL SPECIFICATION left by the said James Hayes (junior) at the
Office of the Commissioners of Patents on the 16th July 1880.
JAMES HAYES, junior, of 18, Hermes Street, Pentonvillo, in the County of
Middlesex. "IMPROVED MEANS FOR FACILITATING THE REMOVAL OF WINDOW
SASHES FOR THE PURPOSE OF CLEANING AND REPAIRING THE SAME."
The object of this Invention is to so construct the window frame that at any
time the window sashes may be taken out for the purpose of cleaning and repairing
the same.
Substantially, the following arrangement I prefer to adopt :-The frame for the
window to be constructed in the same manner as an ordinary frame. The way I
propose to take the sashes out of the frame is as follows:-
I insert one double sheave pulley, in the pulley style, to clear the sliding pocket.
The said pocket to be made of metal or wood; I cut half of the pulley style from
inside lining and parting bead on the right or left hand side of the frame to the
height of the sash which forms a sliding pocket on either side of the frame, which
is opened or closed by incans of an eccentric or crank motion to be turned on the
inside lining by a key or suitable knob, by which, when turned to the right, shuts
the pocket, when turned to the left, opens the pocket, thus allowing either sash to
be taken out into the room.
The cords are so arranged that they are readily taken from the sash and replaced
in the following manner:-A hole is bored in the sash style, and a groove is made
to clear the cord in the usual manner. At the ends of the cords are fixed a piece of
round or square metal which inserts the hole in the sash style, thus taking the
weight of the sash. No inside bead is required to be disturbed.

JAMES HAYES, junior, formerly of No. 18, Hermes Street, Pentonville, but now.
of No. 27, Seward Street, Goswell Road, both in the County of Middlesex.
"IMPROVED MEANS FOR FACILITATING THE REMOVAL OF WINDOW SASHES FOR
THE PURPOSE OF CLEANING AND REPAIRING THE SAME.
Whereas the sashes of ordinary windows are difficult of removal for the purposes
of cleaning and effecting repairs, and the services of skilled workmen are required
to effect such removal Now the object of my said Invention is-so-to-construct such
sliding sash windows and window frames as to prevent such inconveniences from
arising, and afford increased facilities for the taking out, removal, and refitting and
reinstating thereof, and to render the services of skilled workmen unnecessary for
such purposes. And my Invention is such that all ordinary windows and frames
can be altered and fitted in accordance therewith.
The means whereby I effect this object is by inserting in the lower half of the
pulley style of the window frame, and on one side only, a metallic box, which is,
preferably of cast iron, for the sake of cheapness, and facility of making and fixing.
This metallic box is let into the style and fixed by means of screws, as herein after
_ described. In this metallic box I fit a movable style and parting bead, in such a
manner that by turning-a-small-crank fitted inside the box, the moveable style and
bead can be drawn or moved away from the sash towards the back of the box,
whereupon that side of the sash next to the metallic box becomes entirely free, and
can be immediately moved away from the frame, and the whole sash can then be
turned about for cleaning and other operations.
The said moveable style and parting bead is, by preference, mado of wood, but
the same may be of metal if preferred. The back of the style and bead is supported
at its upper part by means of its connection with the said crank, and its lower
part by means of a slotted link screwed thereto, and sliding on a pin, herein after
described. By the removal of such pin the style and bead can also be moved so as
to get at the sash weights for repairs or otherwise.
In order that the sash weight or weights may clear the mechanism inserted in
the said metallic box I require a larger pulley than those ordinarily fitted, and I
sometimes fit two pulleys instead of one large pulley, in order to carry the sash
weight clear, as last aforesaid.
And my said Invention consists also of an improved mode of attaching the sash
line ropes to the sashes. This I effect as follows:-I enclose the knot of the rope
in a short piece of metallie tube, the rope entering the tube through a hole in the
side of the tube. A holo is made in the sash style just large enough to contain this
pieco of tube, and a groove is also cut in the style for the rope to lie in in such
a manner that the rope and tube do not project beyond the outer level of the sash
style. By merely removing the short tube out of its recess the rope is entirely
detached from the window, and it is just as readily again attached thereto, without
the aid of nails or tools of any kind. This short piece of tube may be cylindrical
or square, as preferred.
When the sash, and the style and bead are in their respective places, and the crank
locked, the whole is perfectly secure and has the appearance of an ordinary
window. The crank, when locked, being at a right angle to the back of the style,
the style and bead become thereby fixed and immovable, serving the purpose of
and operating in the same manner as the ordinary style and bead.

page_text: And in order that my said Invention may be more clearly understood, reference
is made to the accompanying Drawings, in which similar letters indicate similar
parts in the several Figures.
Fig. 1 is an elevation of the window, complete, as it appears when fitted with
my said Invention. a is the crank axle, and b is the moveable pin; Fig. 2 is a
perspective view of the metallic box with the style and boad locked in the ordinary
position, as seen from the sash side of the box; Fig. 3 is a similar view, as seen
from the back; Fig. 4 is a side view of the mechanism, as seen with the side of the
box removed, to an enlarged scale, locked; Fig. 5 is a similar view, unlocked;
Fig. 6 is an outside (enlarged) view of the crank axle and tumblers; Fig. 7 is a
view of the end of the sash line with the knot inserted into a short piece of
cylindrical tube g; Fig. 8 is a view of the same, in situ, and Fig. 9 is a similar
view, with the tube inserted at right angles to that of Fig. 8; Fig. 10 represents
the position of the style when the pin b has been removed to the position shewn in
order to attend to the sash weights.
In the several Figures a is the crank, which may be actuated by a square hole
key, or may be fitted with a knob or other handlo; or the crank end may be mado
cylindrical and have a hole bored in the same in order to turn it. When fitted (as
preferred) for a square-hole key I provide a tumbler or tumblers which form an
additional security against the crank being improperly turned. When the
apparatus is locked these tumblers fall into detents in the flange of the crank axle,
as shewn in Fig. 6, but when the key is applied it lifts the tumblers and allows
the crank axle to revolve and actuate the style and bead. d is the moveable style
with the parting bead e attached thereto; ƒ (Fig. 3) is a metallic strongthening
pieco at the back of the style d to stiffen it.
The metallic box is fixed in its place by means of two screws at x, x, at each end
thereof, as shewn in the Drawings, there being sufficient flange provided for that
purpose.
The rake and form of the slotted link m is governed by the "throw" of the
crank, so that as the crank lifts the style and bead the link slides in an angular
and upward direction on the pin b.
Fig. 11 is a full sized view of the crank when unlocked; this Drawing shews the
means by which the key lifts the tumblers, the bead n coming in contact with the
slanting edge of the tumbler, as shewn, thereby lifts the tumbler before the key o
is turned.
The operation of the mechanism is as follows:-When the sashes of the window
are in their ordinary position, as seen in Fig. 1, the mechanism is locked and the
style and bead immovable, and the ordinary stato of the window is as usual. But
when it is requisite to take out the sash or sashes the key is applied at a and the
crank is turned backward; this releases the style and bead from the sash, which
can be withdrawn as before mentioned. If it is also requisite to attend to the
sash weights, the pin b is removed and the style and bead drawn outwards, as
shewn in Fig. 10. The reverse of these operations replacing the sash or sashes,
and making all complete.
Having now described and ascertained the nature and objects of my said
Invention, I would have it understood that I do not confine myself to the precise
details herein described, so long as the distinguishing features of my Invention
are maintained; but what I claim and desire to be secured to me by the herein
before in part recited Letters Patent are,-
1. The general arrangement and combination of parts respectively, together
forming my improved means for facilitating the removal of window sashes for the
purpose of cleaning and repairing the same, substantially as herein before described
and illustrated on the Drawings.
2. The application of a metallic box, with moveable style and parting bead,
supported and actuated by the means, substantially as and for the purposes herein
before described and shewn, or any mere modification thereof.

page_text: 3. The arrangement of detachable sash line, substantially as herein before
described and shewn.
In witness whereof, I, tho said James Hayes, have hereunto set my hand
and seal, this Fifteenth day of January, in the year of our Lord One
thousand eight hundred and eighty one.
JAMES HAYES, JR. (L.S.)
