Sashes, Trap Doors, and the like.
I THOMAS MOORE of Eleven Norwood Street, Belfast in the County of Antrim
in Ireland, Carpenter do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a bar or rod by which a skylight, window
sash, trap door or other frame binged at one side may be opened or shut and retained
in any desired position.
For this purpose I employ a curved or bent bar or rod attached by a pivot to a
plate which is fixed upon or fastened to the light, sash, door or frame on the side
opposite to the hinges and I form cavities or notches at intervals upon one or each
side or upon the face of such bar or rod to regulate the position of the light, sash,
door or frame.
I fix upon the case to which the light, sash, door or frame is hinged, and opposite
to the hinged side, a box carrying a hinged or pivoted lever furnished with a tooth or
teeth to fall into the cavities or notches and hold the curved or bent bar or rod in
position or at any desired height.
In order to prevent the light, sash, door or frame when placed in position from
being shifted by the wind or otherwise moved without manual aid I form the under
face of the cavity or notch at an angle with the front and back of the bar or rod and
make the corresponding face of the tooth or teeth of the lever to correlate with such
face of the cavity or notch.
I may furnish the bar or rod and lever with ropes or cords for opening and shutting
the light, sash, door or frame from a distance and may employ pulleys attached to the
box for aiding the operation thereof.

Improvements in Lifters and Fasteners for Skylights, Window
Sashes, Trap Doors, and the like.
I, THOMAS MOORE of Number Eleven Norwood Street, Belfast, in the County of
Antrim in Ireland, Carpenter 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 :-
The object of my invention is to provide a bar or rod by which a Skylight, Window
Sash, Trap door or other frame, cover or lid hinged at one side or end may be opened
or shut and retained in any desired position.
For this purpose I employ a curved or bent bar or rod attached by a pivot to a
plate which is fixed upon or fastened to the light, sash, door, frame, cover or lid
on the side or near to the end thereof opposite to the hinges and which bar or
rod is curved or bent so as to form the segment of a circle of which the hinges
are the centre or axis. And in order to regulate the position of the light, sash,
door, frame, cover or lid I form cavities or notches close to the pivot above
mentioned and at intervals therefrom upon one or each side or upon the inner or
concave face of such bar or rod.
I prefer to use a cavity or notch cut from near the longitudinal centre of the
inner or concave face of the bar or rod to the longitudinal edge of its outer or
convex face so as to present the form of a wedge with its thick end at or in
such outer or convex face and having the upper face, cut or shoulder in a radial
line across the bar or rod.
Upon the inside of the case to which the light, sash, door, frame, cover or lid
is hinged and at the opposite side or end from the hinges I fix a box or bracket
in or through which the curved or bent bar or rod slides or passes and which
carries a hinged and pivoted lever furnished with a tooth or teeth or a cloven
tongue to fall easily into the cavities or notches of the curved or bent bar or rod
and thereby to hold the light, sash, door, frame, cover or lid in position or at any
desired height or angle.
In order to prevent the light, sash, door, frame, cover or lid when placed in position
or otherwise as desired from being shifted by the wind or otherwise moved without
manual aid I form the lower face, cut or shoulder of the cavity or notch obliquely,
inclining downwards to the outer or convex face of the bar or rod and make the
corresponding edge or edges of the tooth or teeth or cloven tongue of the lever cor-
relative with such face, cut or shoulder of the cavity or notch. And I provide the lever
with a weight or spring which actuates it to drop the tooth, teeth or cloven tongue
into the cavity or notch when brought opposite to it:
There are some modifications of the structure and arrangement above described
which I also employ for fanlights or ventilators opening inwards and the like but
which I need not describe as they will be obvious.

page_text: I may furnish the bar or rod and lever with a rope or cord or a system of ropes and
cords for opening and shutting the light, sash, door, frame, cover or lid from a distance
and may employ pulleys or rollers attached to the box or elsewhere for aiding the
operation thereof as commonly practised.
And in order that my said invention may be more fully understood I shall now
proceed to refer to the drawings on the sheet hereunto annexed the same letters of
reference being used throughout all the figures to indicate the same or corresponding
parts of my apparatus :-
Fig. I. is a side elevation of the apparatus showing the curved or bent bar or rod and
the pivot by which it is attached to the plate upon the light, sash, door, frame, cover
or lid opposite to the hinges or axis; the cavities or notches in such bar or rod and
the box or bracket in or through which it slides or passes: the hinged or pivoted lever
furnished with teeth or a cloven tongue, the weight by which such teeth or tongue
are or is actuated and the cord and pulleys for adjusting the apparatus and
Fig. II. is a front view of the bar or rod, toothed or tongued and weighted lever,
box or bracket and pulley and cord.
a is the bar or rod and b the pivot attaching it to c the plate fixed upon or fastened
to the light, sash, door, frame, cover or lid; d, d are the cavities or notches in the bar
or rod a; e is the box or bracket; is the hinged or pivoted lever having the teeth or
tongue to fall into the cavities or notches d, d and is the weight; h is the cord for
adjusting the apparatus and i is the pulley over which the cord is drawn.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. The use in skylights and other hinged frames, covers or lids of a bar or
rod arranged with cavities or notches substantially in the manner and for the
purposes herein before described and shewn in the drawings hereunto annexed.
2. The use in skylights and other hinged frames, covers or lids or the cases
therefor of a bracket or case arranged with a lever constructed and employed substan-
tially in the manner and for the purposes herein before described and shewn in the
drawings hereunto annexed and
3. The combination and arrangement of parts constituting my improved Lifter and
Fastener constructed and employed substantially in the manner and for the purposes
hereinbefore described and illustrated by the drawings hereunto annexed.
