PROVISIONAL SPECIFICATION.
Improvements in connection with Sashes of Windows, Doors, and
the like.
I, FREDERIC HUGHES, of 20, Paget Road, West Dulwich, Engineer, do hereby
declare the nature of this invention to be as follows;-
My invention relates to the sashes of windows, doors and the like, and the object
is to provide means whereby the sash can be easily raised or lowered to, and
retained at, its required position.
In carrying my invention into, offect, I proceed in or in about the following
manner, premising that although I refer in this specification only to its application
to the sash of a carriage door, nevertheless, I do not confine my invention to that
one use, but may employ it for any purpose to which it is applicable.
In each of the grooves or pully stiles of the frame in which the sash runs, I
provide a rack or equivalent. At each end of the top rail of the sash, I provide a
wheel or pinion having projections around it of such character and the wheels
being so situated that the projections enter and run in the racks above mentioned.
Each wheel turns on or around a central pin or spindle. Along the top rail of
the sash, I provide a bolt or locking lever of such character that each end thereof
fits into a space or into spaces, between two or more of the projections on the pinions
at the ends of the top rail of the sash: The bolt is provided with a cam or other
arrangement, preferably at the centre and has a spring for keeping the ends inserted
in the spaces on the wheels as already mentioned, until withdrawn by operating the
cam or other arrangement by a handle or equivalent provided for the purpose. On
releasing hold of the handle, the spring cam or other action shoots the ends of the
bolt into the spaces above referred to. The action of the arrangement is as
follows;-On turning the handle, the ends of the bolt or locking lever are with-
drawn from the wheels at the ends of the top rail of the sash, and on raising
or lowering the sash the wheels run in the rack or equivalent provided in the
groove of the sash frame, and on the sash reaching its required position, the handle
of the bolt is released from the hold whereupon the spring shoots the bolt ends
into the spaces between the projections on the wheels and so locks the sash in
its required position.

I, FREDERIC HUGHES of 20, Paget Road, West Dulwich, 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:-
My invention relates to the sashes of windows, doors and the like and the object
is to provide means whereby the sash can be easily raised or lowered to and
retained at its required position. In carrying my invention into effect I proceed
in or in about the following manner making reference to the accompanying draw-
ing and premising that although I refer in the following specification only to
its application to the sash of a carriage door nevertheless I do not confine my
invention to that use but may employ it for any analogous purpose
to which it is applicable. The drawing represents a part sectional front
view of part of a
sash fitted with my invention. In each of the
grooves or pully stiles a of the frame in which runs the sash e I provide a rack
or equivalent d. At each side of the sash (preferably at each end of the top
rail !) I provide a wheel or pinion e having round it teeth or projections f of
such character and the wheels being so placed that the projections or teeth enter
and are free to run in the racks already mentioned.. Each wheel e turus on or
round a central pin or spindle g. At each side of the sashi and preferably in the top
rail I provide a bolt or locking lever h. One end of each of the levers his
provided with a pini free to run in one of two eccentrically placed slots; provided
in a disc k free to move on a pin fastened to the rail c. The slots i are so placed
that one end of each is nearer the pin than is the other end. The other end' of
each lever his formed to enter any one of the spaces between two adjacent teeth
or projections in the pinions e. In each lever h is a slot m and in each slot is a
spiral spring n one end of which presses against one end of each slot m and the other
against a stop. o standing up within the slot m but attached to the rail c¹. The
disc may be the only exposed part of the whole arrangement all the remainder
being covered in. To may be attached any suitable kind of handle 2 for use
in raising or lowering the sashi. In assembling the various parts together it is
intended that the pins i at the end of h shall be at that end of their respective
slots m which is farthest from the centre of kat which time the levers will have
their other ends inserted between two adjacent teeth in the pinions e. The action
is as follows; assuming the sash to the in its lowest position. By grasping the
handle p and giving the disc & a partial rotation the slots will act on the pins i
and draw the levers towards the centre of k and so withdraw their other ends
from the space between the teeth on e. The sash is now free to be raised, the
pinions e running in the racks d. When the sash has reached the desired position
it may be kept there by releasing hold of the handle 2, whereupon the spring n
will force out the ends of h and insert each of them into a space in the periphery
of its nearest pinion e.
Instead of a spiral spring an india rubber one may be used, one end of the spring
being attached to the inner end of the slot m & the other end of the spring being
attached to the stop o, which in this case would be placed more towards the outer
end of the slot than is shown in the drawings:.
•
As my invention is capable of considerable variation without departure from its
essential features I do not restrict myself to the precise shapes, arrangement,
deposition, relative proportions or other details as shown in the accompanying
drawing or described in the above specification.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed. I declare that what I
claim is :-
The improved method of and means for retaining the sashes of windows,
doors and the like at any required position between their entirely open or closed
positions, the said means cousisting essentially (a) In providing with racks or
equivalents the grooves in which the sash runs. (b) In providing each side of the
sash with a toothed or other pinion (preferably situated at each end of the top
rail of the sash) each pinion gearing into one of the said racks or equivalents.
(e) In providing the said sash (preferably its ton rail) with locking bolts or levers
one end of each of which enters the space between two adjacent projections or teeth.
on the periphery of the pinions above mentioned, the other end of each lever
having a pin free to run in an eccentrically placed slot provided in a disc or the
like rotatable on a pin attached to the centre or other part of the said rail. (d) In
providing each of the said locking levers with a slot in which operates a spiral or
other spring one end of which is in contact with or attached to one end of the said
slot and the other end in contact with or attached to a stop standing up within
the slot and attached to the rail over or in which the levers move, the various
parts being so arranged that on taking hold of a suitable handle attached to the
above mentioned slotted disc and on partly rotating the said disc, the slots therein
acting on the pins at the ends of the locking levers will withdraw the opposite ends
of the said levers from the spaces between the teeth of the said pinions to which
spaces they will be automatically returned by the action of the above mentioned
springs on releasing hold of the handle of the disc, the whole substantially as
described in the above specification and exemplified in the accompanying drawings.
