SASHES AND SASH FRAMES,"
PROVISIONAL SPECIFICATION left by the said Robert Henry Thompson at
the Office of the Commissioners of Patents on the 16th April 1880.
ROBERT HENRY THOMPSON, of Islington, in the County of Middlesex, Contractor.
"IMPROVEMENTS IN WINDOW SASHES AND SASH FRAMES."
This Invention relates to improvements in window sashes and sash frames, such
as move up and down, and are required to swing or radiate for cleaning or for
other purposes.
The first part of my improvements consists in hingeing or otherwise opening,
closing, or displacing that part or those parts of the sash frame, frames, or framing
which form the side or sides of the groove or grooves wherein the sash line or lines
are fastened to the sash or sashes.
By opening these parts of the framing it gives freedom to the sash or sashes to
swing on the lines to such an extent as to be easily turned inside out.
-
The second part of my improvements relates to the arrangement of the parting
beads, as parts of them aro required to move out of the way so as not to obstruct
the turning about of the sashes.
For this purpose I recess the pulley stile or the pocket pieces in the pulley stiles
of the sash frames, or pulley stiles in such manner as to admit the movable part or
parts of the parting bead or beads to turn in or out of the way of the sash or
sashes. These recesses are fitted with springs or cushions or other suitable
mechanical contrivances, and thin pieces of wood or other material to fit the
recesses are fitted on the top of these springs. The object of these springs and tho
thin pieces of wood or other material is, that when the parting beads are not
required to be moved out of the way of the sashes, these springs force up the thin
pieces of wood to the face of the pulley stile, of which it then forms an even part.
Drin Q11

page_text: But when the parting beads are required to be moved out of the way for the sash
to turn about these thin pieces of wood are pressed down with the springs, aud
the movable parts of the parting beads on them to the level of the pulley stile, and
thus remain as long as is required. These operations can be repeated as frequently
as may be required.
Parts of the stop beads are also moved out of the way by turning them back on
the inside lining of the sash frame. Parts of the outer lining of the sash frame
(which projects before the sash and form guides for it to work in) are made
movable, but these movable parts are jointed on to the fixed parts and can be
turned up out of the way of the sash or sashes when required, and when not
required can be turned down again into their proper places.
Thus all the parts of the stop beads, the parting beads, and the outside lining
can be removed out of the way of the sash, sashes, or windows, at that part of the
frame or framing where it is intended it should be clear, for the purpose of turning
the sashes or windows about when required for cleaning or other purposes. But
when the sash, sashes, or windows are replaced in the ordinary positions, as also
the movable parts of the beads and outside lining into their places (in about two
minutes), they are as wind and rain tight as the movable parts of the outside lining
which are tongued and the frame grooved to receive the tongues, and the framing
is rebated to receive the movable parts of the stop bead or beads.
The third part of my Invention relates to improvements in the sash frame or
frames, or those parts of the sash frame or frames known as the pulley stile or
pulley stiles.
In these pulley stiles I fix a bearing or bearings fitted with radiating centres
which are made to grip the sash or sashes so as to bold the sash or sashes when
required for cleaning or other purposes, or to act as sash fasteners. These centres
do not obstruct the moving action of the sash or sashes in their up and down
movements, but are constructed expressly for the sashes to turn about on or for
securing the sash or sashes from shaking about when required.

page_text: carried into practice, I will proceed to describe the Drawings nereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1, Sheet 1, shows a plan in section of the fixed parts full size of a window
frame, consisting of the inside and outside linings and pulley stilo, part of the sash
or frame a being shown in the position it assumes when displaced and retained in a
horizontal position, in accordance with the first part of my improvements.
Figure 2 shows a section of the sash frame or stile a, the groove or rebate a', and
hinged part a³.
Figure 3 shows a vertical section, and Figure 4 a front view of a pair of window
sashes and frame arranged in accordance with my improvements on a smaller scale
when the sashes are set free and reversed.
According to the first part of my improvements I arrange the sash or sashes a
in such manner that they may be readily caused to swing on the sash lines in
addition to their present up and down sliding action.
For this purpose I remove or displace the side or sides of the groove or grooves
a², a¹, formed in the sash stile or frame a, and in which the sash lines are fastened
to the sash or sashes.
The sash stile or frame a can be made with only one side, as shown at Figure 2,
thus forming a rebate instead of a groove or grooves, but I find it advantageous to
hinge the part or parts a³ that form the sides of the grooves so as to open and close,
as shown by Figure 2, whereby freedom is given to the sash lines to such an extent
as to be easily reversed or turned inside out by swinging on the sash lines into the
position shown by Figure 3.
According to the second part of my improvements I make the stop or parts of
the stop or inside beads b of the sash frame to open and close on hinges, either up
or down, or side-ways, as shown by Figures 1 and 3, Sheet 1 of the Drawings.
I also recess the pocket pieces and the pulley stiles c sufficiently deep at c¹ to
receive a spring or springs cx, the filling up piece or pieces c², and the parting bead
or a part or parts of the parting bead c³, in order that the parting bead or beads c³,
or parts thereof may turn into these recesses, as shown at Figure 1. Thus, part or
parts of the parting bead c³ being turned into the recesses c', and the stop beads or
parts of the stop beads as being turned aside, the sash, sashes, or window will be set
at liberty to admit of the same being turned to any angle, from vertical to horizontal,
as shown by Figures 3 and 5 of the Drawings, either for cleaning, repairing, or
other purposes when required.
The object of the springs c* and filling pieces c2 is, that when the parting beads
c³are not required to be moved out of the way of the sashes the springs c* force
up the filling pieces c² to the face of the pulley stile, of which it then forms an even
part, being retained in that position. But when the parting beads c³ are required
to be moved out of the way for the sash to turn about the filling pieces c² are
pressed down with the springs into the recess, and the movable parts of the parting

page_text: beads on them to be level of the pulley stile, and thus remain as long as is
required.
Parts of the stop beads b are also moved out of the way by turning them back on
the inside lining of the sash frame. Parts of the outer lining of the sash frame
(which project before the sash and form guides for it to work in) are made movable,
but these movable parts are jointed on to the fixed parts, and can be turned up out
of the way of the sash or sashes when required, and can be turned down again into
their proper places when not required.
Thus all the parts of the stop bead b, the parting beads and the outside lining
can be removed out of the way of the sash, sashes, or windows at that part of the
frame or framing where it is intended it should be clear for the purpose of turning
the sashes or windows about when required for cleaning or other purposes.
But when the sash, sashes, or windows are replaced in their ordinary positions, as
also the movable parts of the beads and outside lining in their places (which is
quickly and readily done), they are as wind and rain tight as the movable parts of
the outside lining, which parts are tongued and the frame grooved to receive the
tongues, the framing being rebated to receive the movable parts of the stop bead or
beads.
The third part of my Invention relates to improvements in the sash frame or frames,
or those parts thereof known as the pulley stile or stiles, in which I fix a bearing or
bearings to receive the stem or axis of a rotating clip or holder d, the projecting
jaws d of which are caused to embrace the sash frames so as to hold them firmly
when required for cleaning or other purposes, or to act as sash fasteners when the
window is closed, as shown in Figures 1 and 1*, Sheet 1.
According to another improved arrangement to facilitate the turning action of
window sashes I make the face of the pulley stiles in two or more parts, as shown
in Figures 7, 8, 9, 10, 11, and 12, Sheet 3 of the Drawings annexed.
The stop bead e or parts of the stop bead and parting beads f, or parts connected
therewith, I make either to open or close by hinging them to the pulley stile, stiles,
or lining, or I remove these parts when required.
In the most suitable positions in the pulley stiles I fix metal bearings or sockets
to receive the stems or axes of the rotating clips or holders d, d, formed with
jaws or projections d', d¹, into which the stile or window frame a slides and revolves
with the holder & to any required angle, as shown in Figure 1, Sheet 1.
1 find it advantageous to fix the rotating holders d, d, near to the bottom end of
the pulley stiles, so that when the sash or sashes are turned down into a horizontal
position the holders & act as fulcra, and the fixed parts of the stop bead as supports,
thus taking the strain off the sash lines whilst the sash is being cleaned, repaired,
painted, glazed, or otherwise operated upon; g, g, are sliding bolts to fix the sashes
when required.
Having thus described the nature of my improvements, and the manner of
performing or carrying the same into practice, I would remark that I do not claim
any of the mechanical or other parts separately, which are well known and in
common use, nor do I limit myself to the exact details herein before described, so
long as the novel features or character of my Invention is retained, but what I 4
clain is,―
First. The removal or displacement of the side (or sides) of the grooves formed
in the sash stile or stiles a of window sash frames, or by forming such parts with a
rebate, the side a² being removed or arranged to open and close on hinges or
otherwise, so as to give freedom to the sash lines, substantially in the manner and 5
for the purposes hereinbefore described and represented in Sheet 1 of the Drawings
hereto annexed.
Second. I claim the improved arrangement and construction of window sashes
and sash frames, by forming recesses c¹ in the pulley stiles and pocket pieces, so as
to turn part or parts of the parting beads into such recesses out of the way of the 5
free movement of the sash, substantially in the manner and for the purposes

page_text: herein before described and represented in Figure 1, Sheet 1 of the Drawings
annexed.
I also claim the insertion in the recesses c¹ of the filling pieces c³ and springs c*
for forcing them up to the level of the face of the pulley stiles, and regulating the
position of the same, substantially in the manner and for the purposes herein before
described and represented in Figure 1, Sheet 1 of the Drawings annexed.
Third. The improved arrangement and application of the fixed bearings and
rotating holders d, d, together with the removal or displacement of parts of the
pulley stiles, substantially as and for the purposes herein before described and
represented in the Drawings hereto annexed.
Lastly. I claim the improved general arrangement and construction of window
sashes and sash frames, substantially as and for the purposes hereinbefore described
and represented in the Drawings hereto annexed.
In witness whereof, I, the said Robert Henry Thompson, have hereunto set
my hand and seal, this Fifteenth day of October, in the year of our
Lord One thousand eight hundred and eighty.
