I HENRY AUGUSTUS WILLIAMS of Pyon Lodge Bodenham Road in the County
of Hereford Major retired late 14th Regiment do hereby declare the nature of the
said invention for "IMPROVEMENTS IN MECHANISM OR ARRANGEMENTS FOR RAISING
LOWERING AND SECURING SLIDING WINDOW SASHES" to be as follows:-
My invention consists of the mechanism or arrangements hereinafter described
for raising and lowering sliding window sashes and for securing them in any.
required position.
According to my said invention I mount a screwed shaft or rod vertically in
suitable bearings on either side of each of the sashes and I connect each of the
sashes to two of the. said screwed shafts by means of screw boxes or internally
screwed sockets which work on the screwed shafts the said screw boxes being
connected to the sashes by means of projecting plates formed on the said boxes
which plates are secured to the sashes by screws or other convenient means and
pass through slots formed in the sides of the window frame in which slots the said
plates work when the sashes are raised and lowered. Each of the sashes is thus
connected at each side to one of the screwed rods and may be separately raised or
lowered by simultaneously turning in one or other direction the two screwed rods
to which it is connected.
In order to admit of the two screwed rods to which each sash is connected being
simultaneously turned as required I gear the said rods together in pairs by means
of bevil toothed wheels and two horizontal shafts which horizontal shafts are
capable of revolution independently of each other and are caused to revolve as
required by suitable gearing worked by means of winches or crank handles. Each
of the said horizontal shafts is geared to one of the pairs of screwed rods and is
worked by means of one of the winches or cranks In cases where it is desirable
that the axes of the two horizontal shafts should be coincident I form one of the
said shafts hollow and pass the other of the said shafts through the hollow shaft.
The sashes when closed or raised or lowered to the required extent are secured by
the engagement of catches with notches in discs carried by the axes of the said
winches.

page_text: In applying my invention to very light window sashes I dispense with the
horizontal shafts herein before referred to and gear the winch by which cach sash is
raised and lowered directly to one only of the pair of screwed rods to which the
Bash is connected. In this case each sash is raised and lowered by turning only
one of the screwed rods to which it is connected which rod is turned as required
by means of the winch with which it is geared. Where this arrangement is used
a plain rod may be substituted for that one of each pair of screwed rods which is
not geared with the winch.
By the use of my invention the ordinary sash weights and cords and pulleys and
sash fastenings are rendered unnecessary the opening of the sashes from the outside
is rendered impossible the sashes can be fitted with great accuracy thereby ensuring
freedom from draughts and rattling and the sashes are independently locked or
secured in any desired position whether closed or fully open or partly open.

I HENRY AUGUSTUS WILLIAMS of Pyon Lodge Bodenham Road in the County
of Hereford Major retired late 14th Regiment do hereby declare the nature of the
Baid Invention for "IMPROVEMENTS IN MECHANISM AND ARRANGEMENTS FOR
RAISING LOWERING AND SECURING SLIDING WINDOW SASHES and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
"
My invention consists of the mechanism or arrangements herein after described
for raising and lowering sliding window sashes and for securing them in any
required position.
According to my said Invention I mount a screwed shaft or rod vertically in
suitable bearings on either side of each of the sashes and I connect each of the
Bashes to two of the 'said screwed shafts by means of screw boxes or internally
screwed sockets which work on the screwed shafts the said screw boxes being
connected to the sashes by means of projecting plates or tongues formed on the
said boxes which plates or tongues are secured to the sashes by screws or other
convenient means and pass through slots formed in the sides of the window frame
in which slots the said plates or tongues work when the sashes are raised and
lowered. Each of the said sashes is thus connected at each side to one of the
screwed rods and may be separately raised or lowered by simultaneously turning
in one or other direction the two screwed rods to which it is connected.
In order to admit of the two screwed rods to which each sash is connected being
simultaneously turned as required gear the said rods together in pairs by means
of bevil toothed wheels and horizontal shafts. The two sets of shafts by which the
sashes are respectively worked are capable of revolution independently of each other
and are caused to revolve as required by suitable gearing worked by means of
winches or crank handles.
Figure 1 of the accompanying Drawings is an elevation of a window provided
with mechanism of the kind hereinbefore described for raising and lowering the
sashes the front parts of the frame of the window being removed in order to exhibit
the said mechanism Figure 2 is a section of the window frame without the sashes
the section being taken on the line 1 Figure 1. Figure 3 is a side elevation of the
window frame and the said mechanism Figures 34, 5, 6, 7, 8, 9 and 10 are details
hereinafter referred to. The same letters and figures of reference indicate the same
parts in all the Figures of the drawings herein before referred to.
A is the frame of the window B B' are the sashes CC are the screwed shafts
to which the lower sash B' is connected C' is the horizontal shaft and c', c², c³, care
the bevilled wheels by which the shafts C C¹are coupled together. D (see Figure 3)
is one of the screwed shafts to which the upper sash B is connected and D' is the
horizontal shaft by which the said shaft D is coupled with the other of the pair of
vertical screwed shafts to which the said upper sash B is connected. 'E E are

page_text: the screw boxes on the shafts C C' and E' E are the screw boxes on the shaft D
and the shaft coupled therewith. e, e are the projecting plates or tongues formed
on the said screw boxes which plates or tongues engage with recesses formed in
plates secured to the sashes. A portion of one side of the lower sash with one of
the said plates secured thereto is shown (drawn to a larger scale) in end elevation.
in Figure 4 and in back elevation in Figure 5 b¹ being one of the said plates and
6 the recess therein in which the plates or tongues e, e engage. a³, a³ (see Figure 2)
are the slots in the sides.of the window frame in. which the said plates or tongues
work when the screwed shafts are turned.
The vertical screwed shafts and the horizontal shafts are supported by and work
in bearings F, F, F, F' secured to the window frame. In order to facilitate the
removal of the said shafts from their bearings when required the said bearings F F
are formed in two parts as shown in Figures 2, 3 and 3 the said Figure 3* being
a plan of one of the lower bearings F' The part f¹ of the said bearings which is
separable from the part secured to the window frame is of a dovetail form and is
retained in place by engagement with the correspondingly formed sides of the recess
in which it lies. When the parts f¹f¹ of the bearings are disengaged from the
parts F F and F F¹ the shafts are free to be removed.
The gearing by which the screwed shafts are worked consists of bevilled
wheels g g mounted on an axis G supported by bearings H H' and engaged with
other bevilled wheels c³, secured to the screwed shafts C and D at their lower
ends. The wheel g¹ is secured to the axis G and the wheel g³ has a tube or
sleeve g³ formed on it through which the axis G passes the projecting end of which
tube or sleeve is squared to engage with the key or winch by which the mechanism
is worked. The end of the axis G projects beyond the end of the said tube or
sleeve g and is also squared. The said arrangement of gearing is shown separately
drawn to a larger scale in Figures 6 and 7 Figure 6 being an end elevation corre-
sponding to that shown in Figure 1 and Figure 7 being a longitudinal section taken
on the line 2 Figure 6. The key or winch is shown (drawn to the same scale as
Figures 6 and 7) in Figures 8, 9 and 10 Figures 8 and 9 being elevations of opposite
sides or ends of the key and Figure 10 a central section thereof. The part of the
said key fits on the squared end of the axis G and the part fits on the squared
end of the tube or sleeve g³ of the wheel g².
In using the mechanism herein before described the said key or winch is engaged
with the end of the axis G or with the projecting end of the collar or sleeve g³ on
the wheel g according as the upper or the lower sash is required to be moved and
the said key or winch is turned to the right or to the left according as it is desired
to raise or lower the sashes.
In cases where the screw threads on the vertical rods are of such pitch that tho
sashes may be raised or lowered by pressure thereon I secure them by means of
the following arrangement I mount on the axis G and on the sleeve 9 of the
wheel g² discs having ratchet teeth or notches formed on them with which pawls
engage I prefer however to make the screw threads of such pitch that the sashes
cannot be so lowered.
In applying my invention to light window sashes I use one screwed shaft only
for each sash instead of a pair of shafts and I connect each of the sashes to its
shaft by means of two screw boxes one of which engages with the sash at or near
the upper part and the other at or near the lower part and in some cases in order to
assist in guiding the sashes and to prevent or reduce friction between them and
the frame of the window I mount a plain rod in each of the chases of the window
frame on the side opposite to that on which the screwed shafts are mounted and
I form a groove longitudinally in one side of each of the sashes which grooves
when the sashes are in place lie over the said plain rods and I connect the sashes
to the said rods by means of loops rings eyes or sockets which work on the said
rods and have tongues or plates formed on them by which they are engaged with
the sashes as in the case of the screw boxes in the arrangement hereïn before
described,

page_text: In some cases I connect the two sashes to one pair of shafts having both right
and left hand screw threads formed on them.
Figures 11 and 12 of the accompanying drawings are elevations of a window
frame (corresponding to the views Figures 1 and 3) showing this arrangement.
As will be seen by examining the said Figures 11 and 12 one half the length of
each shaft has a right hand screw thread formed on it and the other half has a left
band screw thread formed on it and the upper sash is connected at the upper part
to the said shafts by screw boxes J J and the lower sash is connected at the lower
part to the said shafts by screw boxes K K. The position of the screw boxes J K
and of the sashes when the window is fully opened is indicated by dotted lines in
the said Figure 11. One of the said screw boxes K is shown separately in plan in
Figure 13. The parts of the bearings and the window frame and sashes are
marked with letters and figures of reference corresponding to those in Figures 1,2
and 3. The mechanism for turning the screwed shafts is similar to that shown in
Figures 6 and 7 except that the wheel gå shown.in the said Figures is dispensed
with one bevilled wheel only being required in consequence of there being but one,
set of screwed rods.
By the use of my invention the ordinary sash weights and cords and pulleys
and sash fastenings are rendered unnecessary the opening of the sashes from the
outside is rendered impossible the sashes can be fitted with great accuracy thereby
ensuring freedom from draughts and rattling and the sashes are independently
locked or secured in any desired position whether closed or fully open or partly
open.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I wish it to be
understood that I do not limit myself to the precise details herein before described
and illustrated in the accompanying drawings as the same may be varied without
departing from the nature of my invention but I declare that what I claim is
First The means hereinbefore described for raising and lowering window
sashes that is to say the arrangement in the frames of sliding sash windows of
vertical screwed shafts supported by and working in bearings secured to the said
frames the said screwed shafts being engaged with screw boxes connected to the
window sashes and the several parts being so arranged that the sashes may be
raised or lowered by turning the said shafts in one or other direction.
Secondly. The general combination and arrangement of parts constituting the
mechanism for raising and lowering and securing sliding window sashes herein-
before described with reference to and illustrated in Figures 1, 2 and 3 of the
accompanying Drawings.
