Improvements in Garden and similar Frames.
GEORGE MORRIS, of Windsor Works, Beeston, near Nottingham, Heating
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in garden and similar frames, and
has for its object the construction of a frame in which the division of the top, which
are generally glazed, may be opened varying distances and be securely held in
their different positions without the use of independent mechanism: also the
arrangement of such means whereby the weight of each division of the frame top
will move the division to its locking position.
According to this invention the divisions of the frame top are fitted with pivots,
and the rafters between the divisions are fitted with slotted bearings to receive the
pivots. These bearings are slotted, and by preference the slots are open at one
end. The slots are placed at such an angle that the weight of each division of
the frame top will force backwards or forwards the division of the frame top into a
position to engage with the holding device which comprises a curved rack with
teeth or recesses fixed to a suitable part of the frame while the frame top is fitted
with a plate having recesses or teeth.
In modifications of the above the divisions of the frame top may have more than
one pivot or there may be more than one slot in the bearing, the curve of the
locking rack being altered accordingly, or the curved rack may be fastened
to the divisions of the frame top and engage with a fixed tooth or recess.
Dated this 28th day of June 1898.

COMPLETE SPECIFICATION.
Improvements in Garden and similar Frames.
GEORGE MORRIS, of Windsor Works, Beeston, near Nottingham, 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 improvements in garden and similar frames, and
has for its object the construction of a frame in which the "lights" at the
top of the same may be opened varying distances, and be securely held in
such varying positions without the use of independent mechanism: also the arrange-
ment of the parts whereby the "lights" will he moved to their locking position
by their own weight.

page_text: According to this invention each "light" is fitted with a pivot which has a
bearing in a bracket on the rafter or frame side, the bearing being slotted to
allow of the light" being moved to and fro therein. The slot of the bearing is
placed at a suitable angle with the frame rafters so that when the "light" is
drawn forward and released the weight of the same causes the pivot to slide back.
wards in its bearing. Fixed to the rafter, the end of the frame or by ether
convenient means, there is a curved rack provided with teeth or recesses and the
upper end of the “light” is provided with recesses or teeth to work in conjunction
with the curved rack and hold the "light" in its desired position.
In a modification the slotted bearing is replaced by a link which is pivotted to
the light and to the rafters or frame end.
"
In the accompanying drawing, which is a sectional elevation of the upper portion
of a garden or similar frame, the slotted bearing arrangement is shown at the
right hand half of the drawing and the link arrangement at the other half.
In the arrangement shown the rafters a are of iron and when used for a double
frame they are bolted together at b and are shaped to receive a rail to which the
lantern dis pivotted in the usual manner. At each side of the rafter there are a
number of recesses e which are arranged in the arc of a circle struck from the
centre of the pivot f of the "light" and at the upper end of the latter there is a
tooth which can be placed in any one of the recesses c.
Referring particularly to the arrangement shown on the right hand side of the
drawing the bearing for the pivot f, is cast on the rafter «, has an opening
through which the pivot can be passed, and is inclined to the upper edge of the
rafter. The distance of the pivot from the upper edge of the "light is about
one quarter the length of the same, and the angle of the bearing is so arranged
that when the "light" is pulled forward to release the tooth h from the recesses e,
the weight of the light tends to turn it round the pivot f as a centre and to force
the pivot to the bottom of the bearing. These actions bring the tooth into
engagement with one of the recesses e and the light is then locked in position.
In the arrangement shown at the left hand side of the drawing, the light is
pivotted at 7 to a link m which is pivotted to a bracket on the rafter a. The
action of the link arrangement is similar to the slotted bearing and sliding
pivot.
For a single frame the rafter is fastened to the back of the same, the "lights"
are glazed in the usual manner and for frames with wooden rafters the racks are
cast and bolted thereto.
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:-
1. A garden or similar frame in which each of the frame lights is so mounted
on the frame that it tends to fall into its locking position and remain in that
position by the action of its own weight substantially as and by the means herein
set forth.
2. A garden or similar frame in which the frame lights are mounted in slotted
b. arings and can be locked in various positions by means of curved racks as
herein described with reference to the accompanying drawings.
3. A garden or similar frame in which the frame lights are mounted on slotted
links and can be locked in various positions by means of curved racks as herein
described with reference to the accompanying drawings.
