EDWIN HENRY HARRIS of Beversbrook Road Upper Holloway in the county of
Middlesex IMPROVEMENTS IN PORTABLE OR REMOVABLE CONSERVATORIES GREEN-
HOUSES AND OTHER STRUCTURES.
The object of my invention is to produce a conservatory greenhouse or other
structure that can easily and quickly be erected or removed while at the same time
it will be very firm and strong and perfectly weather tight.
I will describe my invention as applied to erect a lean-to conservatory or green-
house. The two ends are made of any desired shape or size and the framework of
each end is filled in with glass or with glass and wood or other material combined
and in one of the ends may be formed the door. I then drive into the wall against
which the conservatory is to be erected two or more staples or eyebolts where each
of the ends is to be placed and I fit corresponding hooks in the edges of the said
ends by which books and staples or eyebolts the ends are secured to the wall.
To make this joint weather tight I secure on the lateral vertical edges of the ends
india rubber or other elastic material preferably of a tubular shape which when
the hooks are inserted in the staples or eyebolts is pressed hard against the wall.
The side of the conservatory may be made in one or more pieces or parts and the
framework of each piece is filled in with glass or with glass and wood or other
material combined. The vertical edges of the end and side are rabbeted and
thumbscrews or other fastenings pass through one part into the other to secure the
parts together. Under these corners of the conservatory I may partly sink in the

page_text: ground a brick or stone on which the said corners may rest and if I should deem
it expedient I can make a recess in the upper surface of the brick or stone in which
a corresponding projection on the end or side of the conservatory may engage. If
the side is made in two or more pieces or parts the edges thereof are rabbeted and
can either be secured together by binges or by hooks and staples or otherwise.
The top of the conservatory is also made in one or more pieces corresponding to
the side and the framework of each piece is filled in with glass or other material.
On the upper edge of the side is formed a dowel which fits into a groove in the
underside of the top so that the top can slide up and down on the structure. This
movement is effected and operated by a cord or chain one end of which is attached
to the sliding top while to the other end is secured a counter weight. This cord or
chain passes over a pulley secured on the side of the structure. When the top is
closed the joint is made weather tight by a piece of india rubber or other elastic
material preferably tubular in shape secured on the edge of the top which is pressed
hard against the wall by the counter weight. When the top is made in two or
more pieces or parts the edges thereof are rabbeted and a strip of wood or other
material is placed under these edges which may be grooved on its upper surface.
One end of this strip is secured by a hook which engages a staple or eyebolt in
the wall while the other end has a dovetail tenon fitting in a mortise formed
therefor in the top of the side of the structure. To increase the stability of this
structure I may fit to the inside of the side suitable frames or boards which when
placed in position will act as corner pieces to secure the side and end in place and
will serve also as flower stands.

If the conservatory is not to be placed against a wall I can make another side in
manner as herein before described. The ends also can be made in two or more
pieces if necessary in the same manner. In the case of other structures such as
out-houses or the like I should proceed in the same manner but the sides and ends
and tops may be made of any material that may be suitable or convenient. I
prefer to make all these structures of such proportions that the ends and sides and
tops or the pieces or parts thereof may be as nearly as possible of the same or
similar sizes for convenience of removal: These structures are obviously very
quickly erected and removed while they are perfectly weather tight and the only
parts that are made fixtures are the staples or eyebolts in the wall.
