Compl.te Specification Left, 16th Jan., 1891-Accepted, 21st Feb., 1891
PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Operating
Skylights, Fanlights, and the like.
I, WILLIAM LEGGOTT, of 27, Park Road, Bradford, in the County of York,
Brass Founder and Finisher, do hereby declare the nature of my invention to be as
follows:-
This invention relates to certain improvements in the connection or coupling
between the rotating vertical or angular operating rod or shaft and the rod or
shaft attached to a pitched ceiling, or roof for opening skylights, fanlights and the
like; and has for its object, the combination with the said rods or shafts of a
connecting joint so arranged that it is applicable for coupling the said rods or shafts
at any angle within a range of 90 degrees or thereabouts, in such a manner that,
on rotating one shaft the other is also operated in like manner.
I accomplish my object in the following manner :-
To one end of a rod or shaft is secured a forked joint between the arms of
which is placed a cross bar so arranged that it will move on its axis, and to which
is attached a similar forked joint at right angles to the first named.
To the second named forked joint is firmly secured at right angles thereto
another of similar construction which is attached to a forked joint secured to the
other shaft and with a movable cross bar similar to the one before described.
By connecting the shafts with a coupling constructed as described they can be
rotated without bevel wheels with this advantage, the coupling will adapt itself,
connect and rotate shafts placed at any angle within a range of 90 degrees or
thereabouts, whereas bevel wheels have to be made to suit the angle of the two
shafts.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Operating
Skylights, Fanlights, and the like.
I, WILLIAM LEGGOTT, of 27, Park Road, Bradford, in the County of York,
Brass Founder and Finisher, 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 certain improvements in the connection or coupling
between the vertical or angular rotating rod or shaft, and the rod or shaft attached
to a pitched ceiling or roof; and has for its object the combination with the said
rods or shafts of a connecting joint so arranged that it is applicable for coupling
the said rods or shafts at any angle within a range of 90 degrees or thereabouts
in such a manner that, on rotating one shaft, the other is also operated in like
manner.
In the accompanying drawings
Fig. 1 represents an elevation of two shafts at right angles to each other con-
nected together by my improved coupling.
Fig. 2 is a view of the coupling with the links in another position.
Fig. 3 is a view of the coupling looking in the direction of the arrow, and
Fig. 4 a plan view of one of the cross bars or connecting pieces placed between
the jaws of the forked joints.

page_text: To the shaft A mounted in suitable bearings B may be secured a handle Cor
hand wheel for operating the same, and to the top of the shaft is attached a forked
joint D between the arms of which is pivoted by pins E a cross bar F.
To the said cross bar at right angles to the pins E is pivoted by pins E' a forked
link G the shaft H being attached to one end of the centre or last named forked
link G in a similar manner as shaft A. is to the other as herein before described.
By connecting the shafts with a coupling constructed as described, they can be
placed at any angle within a range of 90 degrees, and rotation from one
shaft to the other transmitted without the intervention of bevel wheels; the pivoted
cross bars in combination with the centre connecting link G accomodating them-
selves to the constantly varying angles during each revolution, whereby a steady
and regular motion is imparted from one shaft to the other, thus by this com-
bination, skylights, fanlights and the like placed on the roof and in other inaccessible
places may be operated from the ground level by shafts placed at various angles
to each other and provided with couplings at the angles constructed as herein
before described.
The skylight or fanlight openers may be of any construction requiring rotary
motion for operating the same, and the connection between the shaft H and the
opener of any suitable character.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same may be performed, I declare that what I
claim is
1. A coupling constructed in the manner as herein before described combined
with shafts and a skylight or fanlight opener for the purpose set forth.
2. The method of operating skylights and fanlights by means of shafts and
couplings the latter being arranged substantially in the manner as shown and
described.
