Improvements in Lifts and in the Means for Raising and Lowering
Window Sashes, Fan Lights, Sky-lights, and other similar or
like Purposes.
We, MARTIN MORGAN of No. 1 Gloucester Road Kensington, S.W. Mechanician,
and ANDREW JEFFREY of No. 1, Gloucester Road Kensington, S.W. Sanitary
Engineer, do hereby declare the nature of this invention to be as follows:-
Our Invention relates to improved means for raising and lowering Window Sashes,
Fan Lights, Sky Lights, Lantern Lights or other similar parts likewise for Lifts, the
object being to provide an arrangement whereby Window Sashes and other similar
objects or parts referred to may be easily and expeditiously raised or lowered as may
be required.
At the side of the Sash and about nearly half way its length we fix a bracket
piece the arm of which is slotted and provided with a thread inside the slot in which
is screwed a threaded connecting arm or link piece, the other end of which is likewise
screwed and works in a threaded slot in a sliding piece or guide. Through this guide
an Archimedean screw is passed and works extending downwards towards the bottom
of the sash and continued in the form of a rod through a bearing fixed in any
convenient part. The end of this rod is passed through a bracket or holder and at
the extremity fits into and forms a spindle for a crown, spur or bevil wheel at the
bottom of the said bracket, and this crown, spur or bevil wheel is made to gear with
another crown, bevil or other wheel corresponding thereto fixed on a spindle in the
side of the bracket and this spindle is provided with a handle for operating the
same.
In the case of a Window, Skylight or other purpose indicated to be raised or
lowered, the action is as follows, viz-The handle is turned causing the crown or
other wheel at the end of its spindle to gear with the lower wheel and the rod and
Archimedean Screw are operated upon and so causes the sliding guide to travel down-
wards and with it the arm or link piece and by its downward action and the bracket

on the side of the sash it pulls the Window, Skylight or otherwise downwards and
to close the same the handle would be turned in the opposite direction.
This arrangement may be duplicated or any number may be used if desired and
is applicable to not only Windows but sliding doors and other similar purposes or
objects but may be employed as a lift in buildings for raising and lowering objects.
In the case of lean too Roof's or other buildings we arrange in somewhat similar
manner for purposes as aforesaid but working a bell crank movement from a fixed
point and raising or lowering in the case of Sky Lights, Fan Lights Lantern Lights
or other purposes.

Improvements in Lifts and in the Means for Raising and Lowering
Window Sashes, Fan-lights, Sky-lights, and other similar or
like Purposes.
We MARTIN MORGAN of No. 1, Gloucester Road, Kensington S.W. Mechanician
and ANDREW JEFFREY of No. 1 Gloucester Road, Kensington S.W. Sanitary
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 :-
Our Invention relates to improved means for raising and lowering window sashes,
Fan-lights, Sky-lights and the like, and is also applicable to lifts, the object being to
provide mechanism, whereby the raising or lowering of the above devices may be
readily and expeditiously accomplished. And in order that our Invention may be
more fully understood we have shewn the same in the accompanying drawing in
which Sheet 1 shows one mode of applying our Invention to the raising and lowering
of window sashes. Fig. 1 being an elevation. Fig. 2 a plan, and Fig. 3 a vertical
section of the same. Sheet 2 illustrates another application of our Invention to a
similar purpose. Fig. 1 being an elevation and Fig. 2 a vertical section thereof.
Fig. 1 Sheet 3 illustrates the application of our Invention to a sky-light. Fig. 2
shewing a similar application for the purpose of operating a lift.
the same sheet are details of the hinge shewn in Fig. 1 Sheet II.
Figs. 3 & 4 of
As shewn in Figs. 1, 2 & 3 of sheet 1 we arrange in the right hand side box
shaped frame B of the casement C a mechanism composed of two rods which
have a screw threaded part p p and a smooth part pl pl at each end. These rods
carry bevil wheels w to on their lower extremities which gear with other bevil
wheels w² w³ keyed on shafts ss supported respectively at a a¹ in superposed cast
iron boxes as shown in Fig. 3. The outer extremities of these two shafts s s¹
project in openings o o' formed respectively in the boxes bb and are designed to be
rotated in turn and when required by a crank handle h. The rod is moved by its
screw threaded part through à tapped hole of the strap or follower t fixed to the side
of the lower window sash, while the rod is moved in a similar manner through
the follower attached to the upper window sash. Whenever it is required to
move either window up or down, the handle is placed in the corresponding
opening oor o¹ and either the rod or is set in motion in one direction or in the
other according as it is required to lower or raise the corresponding window W
or W¹.
In the modified arrangement shewn in Figs. 1 & 2 Sheet II we employ one single
rod r instead of two as in the arrangement above described and this rod is provided
along its upper half with a screw thread having a reverse direction to that of the
thread formed on its lower half there being a piece of the rod left smooth at a between

page_text: the two threads and at the outer extremity of the rod which extremity carries a
bevil wheel w gearing with another similar wheel w mounted on a shafts suitably
supported in a cast iron box. The free end of this shaft passes through an opening o
formed in the box and receives the crank handle when required to be turned in
one direction or the other. The rod passes through two boxes e and e' superposed
and screwed outside the further inwardly projecting part of the window casement as
shewn in Fig. 1. Two straps or followers t t fixed one to the lower window W by
means of a hinge H of special construction hereinafter referred to, and the other to
the upper window W by means of a plate i, are provided with a tapped tubular part
through which work respectively the two screw threaded ends of the rod r. The
hinge H shewn in detail in Fig. 3 when open, and in Fig. 4 Sheet 3 when closed
serves to disconnect, and connect respectively the strap t from or to the side of the
lower window sash according as it is required to move the upper window Walone
or to move the two windows simultaneously. Owing to the arrangement of the two
reverse screw threads on the rod when the hinge is closed on to the sash as shewn in
Fig. 1 Sheet II and hence when the strap t is connected to the sash of the window W,
by applying the crank handle to the opening o and turning in one direction the
upper window W will descend, and the lower window W will ascend while by turning
the handle in a contrary direction a reverse but corresponding motion of the windows
will follow.
By opening or disengaging the hinge H from the lower window sash, the upper
window alone can be moved when the handle is turned. In Fig. 1 Sheet III is shewn
an arrangement for raising and lowering a sky light S. In this case we place a rod r
along the wall Wand cause it to work through guides y g' g² g³ fixed to the wall, the
latter limiting the motion of the rod ri.e. when the sky light is closed. This rod
is provided at its upper extremity with a screw thread working in the tapped tubular
portion of the follower fixed to the bar or lever / connected by means of a
leverage 13 to the sky light S and to the frame work which serves as bearing
point. The lower end of the rod carries a bevil wheel w gearing with another
bevil wheel w¹ mounted on a shaft s conveniently supported in a cast iron bar band
whose free extremily passing through an opening o of the latter receives a handle h
designed to set the rod in motion. By turning the handle in one direction or
another the screw rod will cause the follower to move up or down pushing the arm or
lever forward or drawing the same backward and hence closing or opening the
sky light.
Fig. 2 Sheet III shews the application of our Invention to a lift consisting of a
platform P carried by a hollow tubular stem S joined thereto by brackets B. B₁ and
tapped inside so as to move up and down upon the screw rod whose lower end
carries a bevil wheel W rotating upon an axis A forming part of the pillar N, and
gearing with a gearing train T which is actuated by the crank handle h which handle
may however he replaced by a pulley actuating with the aid of a strap by a motor
pulley.
