"Improvements in or relating to Lath Blinds for Conservatories or
Outdoors, and in Means or Appliances for Operating them."
We, HENRY CLARKE, of 21 Beryl Road, Hammersmith, London. Blind Maker and
Upholsterer, and ARTHUR COLLIER, of 4 Wellington Square, Oxford. Shop Assistant.
do hereby declare the nature of this invention to be as follows:-
This invention has reference to certain improvements in or relating to lath Blinds
for Conservatories or outdoors, and in menus or appliances for operating them.
To carry our invention into practice, we fit pivot pins to project from the ouds of
the laths and near to the corner, so that they can engage in holes of side plates for
turning over in either direction. These side plates have V shaped or angled
projections on their upper edges as rests for the latha when moved over to lie
on them.
One end of each lath carries a second axle pin and these engage in the slots of a
sliding plate, and this by a tumbler plate connected therewith, and by a cord or
chain can be pulled over on its centre pin and so pull or push all the laths of the
Blind simultaneously and to any desired anglo to shield the glass or entry from the
Sun's mys, or be laid nearly flat to shield the glass or entry from Rain and Wind.
If the pivot pins and axlo pins be differently arranged on the laths, the side plate
with the holes can be moved for throwing or pulling the laths over.

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 has reference to certain improvements in or relating to lath Blinds
for Conservatories or outdoors, and in means or appliances for operating tliem.
To carry our invention into practice, we fit pivot pins to project from the ends of

page_text: the laths and near to the corner, so that they can engage in holes of side plates for
turning over in either direction. These side plates have V shaped or angled
projections on their upper edges as rests for the laths when moved over to lie on
them.
One end of each lath carries a second axle pin and these engage in the slots of a
Bliding plate, and this by a tumbler plate connected therewith, and by a cord or chain
can be pulled over on its centre piu and so pull or push all the laths of the Blind
simultaneously and to any desired angle to shield the glass or entry from the Sun's
rays, or be laid nearly flat to shield the glass or entry from Rain and Wind.
Our invention well be well understood by reference to the annexed drawings.
Figure 1 side elevation of a side plate with four slats or laths in upright position
and with the pull over plate on the end.
Figure 2 a front elevation with the slats or laths laid horizontally and overlapping.
Figure 3 side elevation of a portion of a side plate.
Figure 4 plan showing the slats fully open.
Figure 5 perspective elevation of a lean-to Greenhouse with our invention applied.
This last view is only an example of the use of our invention, it being equally
applicable to all kinds of outside employment and the slats or laths need not be plain
as they can be corrugated and available for the dark Rooma of Photographers for
giving the full light of day into a Room when no developing is being carried on and
then to be closed to shut out the light.
A, A, are angle iron plates but these may be of wood or other material if so desired,
to which the slats or laths B, B, are pivotted at C, C. D, is a bar on one side only
to which by other pivots E. E, the laths or slats are also attached. These pivots enter
the sliding bar D which rests and is free to slide upon the angle iron strip plates A A
when the outer button or turn over plate F is moved in either direction by the pull
cord or chain G, said turn over plate being at the side of the angle iron A and
pivotted to a projecting end thereof.
The sliding bar D has a serrated top edge forming V shaped recesses as rests for
the Inths to lie in. The bar D has a stud pin H working in a slot of the pull plate
and this governs the motion of the slide bar D and consequently the pivot pins C, E,
the laths or slats whether they should be set vertically or horizontally can be turned
if used for roofing, but if fitted to ordinary Window Sash openings the slats or laths
when opened would be horizontal, and when closed would be vertical.
For Warehouses, Stores, Sheds, and places that require to be closed against the
action of the weather for the protection of perishable Goods, also Stables, the
invention will be found of great value, particularly if the slats or laths be of Iron,
they can be shut and opened as desired for the admission of light whether it he
for the roofs only, or for windows, or other openings, and whether the Sashes be glazed
or not, a simple movement of the tumbler plate F being all that is necessary.
The overlap of the slats or laths make a slauting roof perfectly Rain tight, and in
the case of Greenhouses, Conservatories, and like Structures, the slats can be turned
as a shield to the Sun's rays.
The invention will be of great service for houses having exotic Plants, Cucumber
houses, Grape houses, and the like, where bottom ventilation is essential to prevent
Mildew, it also facilitates for positive closing against draughts and night air.
We wish to observe that our invention can be as a distinct Structure to be fitted on
or in place and is removable as a body at any time without disturbing any part of a
Building.
We are aware that Venetian Blinds exist and that similar appliances can be found
in practice, therefore we make no claim to anything already in use.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is:-
The appliances arranged for action in the manner described in the foregoing, the
several parts being so adapted that by a pull on a cord or chain, and by the sliding of

page_text: a bar to which the laths or slats are pivotted, said laths or slats can be moved over
to form a screen to shut out light, or be opened to admit light as set forth and in the
manner shown.
