Improvements in Window Sashes.
'I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil 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;-
This invention relates to a window sash, and particularly to supports for the
sash, and some of the objects of the invention are to provide means for revolving
or turning the sash inwardly or outwardly for the purpose of ventilation and to
afford access to both sides of the sash when cleaning the same, to provide a simple
and effective device for retaining the end of the sash weight support, to produce
means for regulating the intensity or force of the anti-rattling mechanism and to
provide means for turning the sash inwardly to a horizontal or oblique position
when there are grills or bars rigidly secured outside of the window frame, which
prevent the revolution of the sash; and with these and other objects in view the
invention consists substantially in the construction hereinafter more fully described
in the following specification and illustrated in the accompanying drawings, in
which,
Fig. 1 is a front elevation partly broken away of a window frame provided with
my improvements;
Fig. 2 is a longitudinal section on line 1-1 of Fig. 1, showing the sliding stiles
and edge of the lower sash in elevation;
Fig. 3 is an elevation view of one of the sliding stiles on an enlarged scale, parts
being broken away;
Fig. 4 is a longitudinal section taken on line 3-3 of Fig. 3;
Fig. 5 is a view similar to Fig. 1 showing the sash eccentricly pivoted.
Fig. 6 is a view corresponding to Fig. 2 illustrating eccentricly pivoted sash.
Fig. 7 is an elevation view on an enlarged scale of the sliding stiles for an eccen-
trically pivoted sash;
Fig. 8 is a section taken on line 7-7 of Fig. 7, and,
Fig. 9 is a horizontal section of the window frame and sash, the latter being
arranged in the same horizontal plane.
Similar characters of reference designate like parts throughout the several views.
Referring to the drawings, and particularly to the construction illustrated in
Figs. 1 and 2 thereof, the reference numeral 1 designates the lintel or top stile, 2
the sill and 3 and the right and left stiles of an ordinary window frame, pro-
vided with the usual dividing strips or beads, 5, 6 and 7 between which the sash 8¹
and 91 slide.

page_text: The sash is preferably made slightly less in width than the distance between
the beads 5, 6 and 7, as shown, so, that when drawn inwardly the sash will not
impinge against beads, and the edges of the sash are ploughed out to form a
longitudinal concave groove 8 therein, as shown in Fig. 2, and staples or similar
articles 9 are driven in to the edge of the sash within the groove formed therein,
adjacent to the ends of the sash.
The window frames are provided with the usual sash-cord pulleys 10, over which
the chain or support 11 runs and to one end of the chain 11 is attached a weight
(not shown) or similar device, in the usual manner, and connected to the other or
free end of the chains or supports 11 are sliding stiles or bars 12, having a convex
longitudinal rib formed centrally thereon, adapted to enter the concave groove 8
in the edge of the sash, as will be readily understood.
An oblong recess 13 is formed in the sliding stiles 12 near the upper end thereof
and from the upper ends of the recess 13, a groove 14 extends to the end of the
stile, adapted to receive the chain or support 11, as shown in Figs. 3 and 4, and
within the recess 13 in the sliding stiles 12 is secured an oblong frame or chain
hanger 15, of metal or other suitable material, preferably provided with a central
circular opening 16 beyond which is an approximately rectangular opening 17,
and the upper end of the frame terminates in a right angular extension 18, which
may be rounded or curved upon the outer side, and formed in this extension 18 is
an opening 19, adapted to register with the groove 14 in the sliding stiles 12, when
the frame 15 is in position therein, so that the chain 11 is passed into said groove 14,
and through the opening 19 and the extremity is secured in position therein by
means of a spring clip or retaining device 20, preferably of the construction shown,
constructed of wire, or spring metal, having a receding or outwardly curved inter-
mediate portion 21 to engage the link or loop of the chain 11 and from the curved
portion 21 the side portions are bent outwardly and then inwardly to form the
segmental spring arms 22 having shoulders or elbows 23, adapted to engage the
sides of the extension 18 surrounding the opening 19 therein and thus prevent
the chain and device 20 from disengagement with the chain hanger 15, as shown
in Fig. 3 of the drawings.
Formed on the chain hanger 15 between the central opening 16, and the rect-
angular opening 17 is a laterally projecting segmental flange 24, and opposite the
flange 24, on the other side of the central opening 10 is a segmental rim or shoulder
25 and below this rim is an oblong opening 26 and in the extremity of the chain
danger is formed a tubular portion 27, through which passes a securing and
adjusting bolt 28, as clearly shown in Fig. 4; and I preferably round the ends of
the chain hanger and upon the upper inner corners of the same are formed spurs or
pointed projections 29, adapted to enter the walls of the recesses in the sliding
stiles 12 and prevent the disengagement of the forward part of the chain hanger."
Mounted upon the chain hanger 15 are spring-operated plates or
anti-rattlers 30, provided at one end with inwardly directed conical
extensions 31, and surrounding said extensions are spiral or other springs 32,
adapted to force the sliding stiles or bars 12 against the outer edges of the sash to
produce a tight joint and at the same time, take up all "play" or lateral move-
ment of the sash and stiles 12 between the stiles 3 and 4 of the window sash and
thereby prevent rattling of the sash, while the stiles or bars 12 are permitted to
move outwardly toward the window stiles 3 and 4, against the action of the
springs 32, when the sash is forced out of allignment with the stiles or bars 12, as will
be readily understood.
The free ends of the plates 30 are preferably rounded as shown in Fig. 3 and the
outer edges of said ends are beveled or inclined to prevent engagement with the
inner faces of the stiles 3 and 4 of the window frame when the sash are moved up
and down, and said plates 30 are preferably provided with sockets 34 surrounding
the opening through which the bolt 28 passes to prevent the rotation of the nut 35,
the bolt being inserted from the convex face of the sliding stiles 12, and preferably
having a screw head to provide for the rotation thereof.

page_text: The sliding stiles 12 are provided at their lower ends with similar spring-
operated plates or anti-rattlers 36, secured by means of adjusting bolts 37, in a
suitably formed recess 38 in the sliding stiles, as clearly shown in Figs. 3 and 4
of the drawings and the conical extensions of the plates 30 and 37 register with
and are forced against the staples 9 in the concave groove of the sash, so that the
inward movement of said plates is limited or controlled, as is shown in Fig. 4 of
the drawing.
The pivotal connection between the sliding stiles 12 and the sash, consists in a
pivot plate 39 secured to the edge of the sash by screws, or otherwise, flush with
the face thereof, said plate having a tubular projection 40 and being provided with
a recess 41 upon the under side thereof and mounted in said tubular projection 40),
is a pivot pin 42 in which is secured a cross-pin or stop 43, adapted to enter the
recess 41 in the under side of the pivot plate 39, and secured within a recess formed
in the sliding stiles 12 is a casting 44, having disk-like attaching flanges or exten-
sions 45, through which pass attaching screws or bolts 46, and the central portion
of said casting is recessed as shown and the bottom thereof is provided with a
central opening 47 to receive the tubular projection 40 on the pivot plate 39, and
upon the pivot pin 42, and within said recèss is a spiral or other spring 48, retained
in position by a disk 49 secured upon the pivot pin 42 by a split key 50.
The operation of the invention will be readily understood from the foregoing
description when taken in connection with the accompanying drawings, and the
following explanation thereof.
The sliding stiles are pivotally connected with the sash, as shown in the draw-
ings, and the same are then placed in position within the window frame after
having connected the chains to the chain-hangers, as described; and when it is
desired to tilt the sash it is only necessary to move the same out of engagement
with the beads on the window frames and either pull the top sash inwardly or push
the bottom outwardly until the sash assumes the desired position.
In Figs. 5-8 I have illustrated eccentrically pivoted sash, adapted to be used
when bars or grills 60 are secured outside of the window frame and prevent the
sash from revolving if concentricly pivoted; and in this construction I preferably
secure a stop block, or other device 51 between the beads 52 and 53 of the window
frame 54, to limit the downward movement of the top sash 55, and secured in the
bead 53 are stop pins or pegs 56 to engage the lower portions of the sash when
the same are tilted and prevent the complete revolution thereof.
In this construction the pivot mechanism 57 is attached to the sliding stiles 58
near the bottom thereof, as shown in Figs. 6, 7 and 8; that is the sash 55 and 59
are eccentricly pivoted; but with the afore mentioned exceptions the construction
and arrangement of parts are substantially the same, and a detailed description
thereof is unnecessary.
When it is desired to tilt the sash, or move the same out of a vertical plane, the
upper part of the sash, shown in Figs. 5 to 8, may be pulled inwardly until the
short or lower end thereof contacts with the stop pin 56, as clearly shown in Fig. 6
and the sash will occupy a horizontal position and the upper sash may be lowered
until it strikes the stop block 51 when it too, may be drawn inwardly into a
horizontal position. I do not confine myself to the specific construction herein
shown and described and I reserve the right to make all such changes and modi-
fications of the same as come within the spirit and scope of my invention.
