PROVISIONAL SPECIFICATION.
Improvements in and in connection with Show Cases and the like.
I, EMANUEL HENRY LEVI, of Fillebrook House, Fillebrook Road, Leytonstonė,
Gentleman, do hereby declare the nature of this invention to be as follows:-
-
This invention for improvements in and in connection with show cases and the
like has for its object an improved construction whereby the lids or covers thereof
can be lifted up for obtaining access to the contents of the case and will retain any
desired position or will be caused to complete the opening movement and the lid
or cover retained out of the way until closed again, and consists essentially in form-
ing on or attaching to the lid or cover of the case a lever extension provided with
a balancing or slightly over balancing weight whereby when the lid or cover has
been partially opened it will retain any desired position or will be caused to com-
plete the opening movement and the lid or cover is retained out of the way until
again closed.
In carrying this .invention into practical effect the lid or cover (generally of
glass and hinged at the back of the case) is provided with a metal bar at each side
extending past the hinges and forming lever extensions of the said lid or cover.
To the outer ends of these lever extensions, weights are attached by means of
chains or the like, so as to hang down at the back of the case out of sight. These
weights may be so adjusted as to balance the weight of the lid or cover so that
when opened the lid or cover will retain any position but are preferably adjusted
to slightly over-balance so that when the lid or cover is opened it will be caused
to complete the opening movement. As with such cases the lid or cover is generally
slightly inclined it will remain in the closed position, but if necessary a catch or
fastening may be provided.
Instead of the weights hanging down at the back of the case, the chain to which
the weights are attached may be passed over pulleys and the weights arranged to
hang down below the case or at any other convenient position.
Instead of using hanging weights, fixed weights may be attached on the end of
the levers to form the balance for the cover, or, instead of fixed weights rollers
may be used.
The same or similar arrangements can also be applied in other circumstances
where lids or covers are lifted to open.

Improvements in and in connection with Show Cases and the like.
I, EMANUEL HENRY LEVI, of Fillebrook House, Fillebrook Road, Leytonstone,
Gentleman, do hereby declare the nature of this invention and in what manner
Price 8d1

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention for improvements in and in connection with show cases, and the
like has for its object an improved construction whereby the lids or covers thereof
can be lifted up for obtaining access to the contents of the case and will retain any
desired position or will be caused to complete the opening movement and the lid
or cover retained out of the way until closed again, and consists essentially in form-
ing on or attaching to the lid or cover of the case a lever extension provided with
a balancing or slightly overbalancing weight whereby when the lid or cover has
been partially opened it will retain any desired position or will be caused to com-
plete the opening movement and the lid or cover is retained out of the way until
again closed.
In carrying this invention into practical effect the lid or cover (generally of
glass and hinged at the back of the case) is provided with a metal bar at each side
extending past the hinges and forming lever extensions of the said lid or cover.
To the outer ends of these lever extensions, weights are attached by means of
chains or the like, so as to hang down at the back of the case out of sight. These
weights may be so adjusted as to balance the weight of the lid or cover so that
when opened the lid or cover will retain any position but are preferably adjusted
to slightly overbalance so that when the lid or cover is opened it will be caused
to complete the opening movement. As with such cases the lid or cover is generally
slightly inclined it will remain in the closed position, but if necessary a catch or
fastening may be provided.

Instead of the weights hanging down at the back of the case, the chain to which
the weights are attached may be passed over pulleys and the weights arranged to
hang down below the case or at any other convenient position.
Instead of using hanging weights, fixed weights may be attached on the end of
the levers to form the balance for the cover, or, instead of fixed weights rollers
may be used.
And in order that this invention may be more clearly described reference is had
to the accompanying sheet of illustrative drawings on which Fig. 1 is a sectional
view of a show case fitted according to this invention. Fig. 2 shows a modified
arrangement in which a triangular weight is employed and Fig. 3 shows a further
modified arrangement in which a rolling weight is employed.
Referring first to the arrangement shown in Fig. 1, the case A is provided with
a glass lid B hinged at C. At each side of the lid B a bar D is attached and these
bars D extend past the hinges C and form lever extensions. To the bars D chains
or cords E are attached and weights F are hung on said chains or cords E. These
weights Fhang down at the back of the case out of sight somewhat as indicated.
The weights F may be so adjusted as to balance the weight of the lid B. When
the lid B is lifted it will then retain any position. Preferably however, the
weights F slightly overbalance the lid B so that when it is lifted, the weights
cause it to complete the opening movement. Also owing to the inclined position
of the lid B when closed in the case of showcases of the class illustrated, the lid
will tend to remain in the closed position. A catch or fastening may be provided
if found necessary. Instead of the weights F hanging down at the back of the
case as shown, the chain E may be passed over pulleys so that the weights F hang
down below the case or at any other convenient position.
.
Generally two weights F will be employed, one at each side of the case but if
desired several may be fitted along the width of the lid.
In the arrangement shown in Fig. 2 fixed weights are employed instead of the
hanging weights F. A triangular weight G is supported on the ends of the bars D
somewhat as shown, and is preferably equi-lateral. While in the closed position
the centre of gravity of the weight G is near the hinge C and the weight conse-
quently acts at a short leverage and causes the lid B to remain closed or causes
it to close if only slightly open. When however the lid is opened about halfway
the weight G balances the lid B and it will retain that position. With any further

page_text: opening movement the weight G acts at a greater leverage and the lid B opens
until the weight G comes in contact with the sloping back A' of the case A.
It will therefore be seen that the lid will take up either a fully open or a fully
closed position and the movement is more gradual than with the hanging weight
first described.

In the arrangement shown in Fig. 3 instead of fixed or hanging weights, a
rolling weight is employed. Extensions of the bars D are formed with slots D2
in which the pivots H¹ of the roller H can roll. When the lid
closed the roller H rests at the inner ends of the slots D³.
When however the lid is lifted the roller H rolls to the outer position and therefore
acts at a greater leverage and, as in the previously described arrangements causes
the lid to complete the opening movement. The same or similar arrangements
can also be applied in other circumstances where lids or covers are lifted to open.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;-
-
(1) In show cases and the like in which the lid is lifted to open, providing lever
extensions to the lid supporting weights at the back of the case so that when the
lid is lifted it is caused to complete the opening movement or when closed it will
remain closed, substantially as described.
(2) In show cases and the like in which the lid is lifted to open, bars D extend-
ing beyond the hinges C and forming lever extensions, chains or cords E attached
thereto and weights I supported by said chains or cords E substantially as described
with reference to Fig. 1 of the accompanying drawings and for the purposes
specified.
(3) In show cases and the like in which the lid is lifted to open, bars D extend-
ing beyond the hinges C and triangular weight G so arranged that the weight acts
either to cause the lid to fully open or to fully close, substantially as described with
reference to Fig. 2 of the drawings and for the purposes specified.
(4) In show cases and the like in which the lid is lifted to open, bars D having
extensions D beyond the hinges C, slots D² formed in said extensions D' and rolling
weight H adapted to roll in said slot 12 substantially as described with reference
to Fig. 3 of the drawings and for the purposes specified.
