BERNARD CLARKE 176 Golden Hillock Road Small Heath Birmingham Manager
of Joinery Works do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS USED FOR OPENING AND CLOSING LIGHTS, SHUTTERS, VENTILATORS,
AND THE LIKE to be as follows:-
The primary application of this invention is for opening and closing lights and
ventilators as used in greenhouses but it is also applicable for other purposes. By
its use the power required for opening or closing lights &c is applied in a direct line
and the lights &c to which it is applied is held firmly and secure at an angle without
the intervention of levers, it consists of a bracket of suitable form for attachment to
any convenient support, its outer extremity or other point, at which the lifting
mechanism is applied carries a swivel bearing through which a spindle of suitable
proportion passes, the one end of this spindle is provided with a winch handle, the
other end with a collar working against the face of the swivel bearing before
mentioned and terminating in a screw of V, square or other section. This screw
works into a nut terminating in a tube of sufficient length to form a shield for
protection of the screw spindle and at the same time a direct connection with the
attachment of the lights &c. This tube can be of any convenient length and can
be connected directly to the connection on the light &c or it may be of a com-
paratively short length, the remainder of the connection being made up with a rod
attached to it. Its application is as follows:
The bracket being suitably secured and connection established between the
light &c. the winch handle is revolved to right or left as may be desired, when the
threaded part of the spindle passes into or out of the nut, and the rod being
extended or contracted thereby the light is opened or closed accordingly the motion
being positive and secure, and always in a direct line owing to the swivel bearing
accomadating, itself to the various angles, depending upon the amount of opening
given to the lights &c. &c.

Lights, Shutters, and the like.
I BERNARD CLARKE of 176 Golden Hillock Road Small Heath Birmingham,
Manufacturer, do hereby declare the nature of said invention for "IMPROVED
APPARATUS FOR OPENING AND CLOSING VENTILATORS SHUTTERS AND THE LIKE
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention has for its object the production of means or appliances, whereby
hinged ventilators, fanlights, shutters and other like objects, can be efficiently and
expeditiously opened and closed.
By my improvements, the motion or force on opening and closing is applied in a
direct line, or at any angle, without the intervention of levers or their equivalents,
and my said invention consists essentially of an attachment or supporting bracket,
with a bushed bearing at its outer or upper end, wherein a swivel spindle or bearing
works, and to the outer end of this spindle a crutch or T bushed sleeve is situated,
wherein the plain part of a screwed spindle rotates; and at the lower extremity of
this spindle winch or handle is secured, while the upper or other end is wormed
and screws within a nut or screw box, secured to the terminal lower end of a
connecting rod carrying barrel, and the terminal end of which rod, is connected to
one arm of a lever jointed about its middle, which is connected to the outer end
of a skylight or ventilator through the intervention of a link.
If necessary, the end of the connecting rod itself may be connected directly to
the glazed window or other object to be opened, by making the connection through
the intervention of a link only.
Having described the nature of my invention, I will now proceed to describe
with reference to the accompanying drawings, the manner in which the same is to
be performed.
Figure 1 represents in side elevation an apparatus or an appliance for the opening
and closing of windows and the like provided with improvements made according
to my invention. Figure 2 represents upon an enlarged scale, that portion of the
appliance containing my improvements, which is shown partly in section and partly
in elevation.
Figure 3 represents a longitudinal vertical section of figure 2, with the bracket
turned round and the handle in the reversed position. Figure 4 shows a vertical
section of the joint of the swivelling arrangement; the section is taken upon the
dotted lines A B figure 2.
The same letters of reference indicate corresponding parts in the several figures
of the Drawings.
a is the carrying and supporting bracket of the appliance, and which said
bracket is affixed to any convenient framing or part of a building or erection. a³ is
an angular attachment flange, secured in position by pins or by other means. The
other end of this said bracket is provided with an extended bushed bearing a³,
within which a neck 6' of a pivot axis brotates and works. The other end 6³ is

page_text: made in the form of a crutch or cross head bearing, and disposed at right angles to
the other bearing 62. And within the said bearing 63 the spindle or plain part c³
of the wormed rod c rotates, on being turned by the winch handle d. c³ d³ are
shoulders formed respectively by the boss c and shank d' of handle d.
e is a screw box connected to the lower extremity of a connecting rod carrying
barrel f. g is the connecting rod secured at its lower end to the barrel, and at its
upper end to a lever h, jointed about its middle at h²; this lever or jointed arm is
connected to the frame of a skylight or ventilator i through the intervention of
the link j, so that on the winch handle being turned, the raising or lowering
mechanism is allowed to follow the varying angular motion of the light or
ventilator.
Thus when a light or ventilator requires to be opened, the winch handle dis
rotated while the combined barrel and screw box remain stationary by its connec-
tion with the link and lever hj; the resultant is, that the barrel and its connecting
rod is raised, and the light or ventilator to which it is connected, thereby opened,
by the direct impelling action of the screw, which constantly changes its inclination,
or angular direction, as the opening of the window proceeds, by the opening
appliance swivelling upon the neck 62 of the cross spindle b; so that on the
appliance being operated for opening and closing, it constantly changes its inclina-
tion, in the same plane as the window is opened; that is, as the angular direction
of the window changes, so the appliance swivels upon the neck b², as represented
in the dotted lines figures 3 and 4, thus obtaining a mechanical advantage by
which the impelling force acts directly in a line with the object to be raised or
opened.
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
First Making or causing the joints of ventilator, skylight and other like
opening and closing appliances or apparatuses of the kind herein described swivel,
or turn by, or upon, and within a standing out arm or bracket spindle b, 63, whose
trunnion like neck 62, works within, and is supported by an outer bearing end a³
of a fixed bracket a, substantially as, and for the purpose herein described and
set forth.
Secondly-The construction and arrangement, or combination of the parts of
appliances or apparatuses for the opening and closing of ventilators, skylights and
the like, consisting essentially of a bracket a with bearing a³, swivelling spindle
or arm b, with bearing and socket 62, 63, screwed rod c, with neck and shoulder c² c³,
winch handle d, and shank d³, harrel, screw box, and connecting rod e, f, g,
all constructed and combined for the purpose, substantially as described and
illustrated.
