Improvements in Wall Elevators for Library and Office Maps.
GERALD STANLEY PHILIP, 32, Fleet Street, London, E.C., Publisher, do hereby
declare the nature of this invention to be as follows:-
I provide a wooden upright for fixing to the wall or partition and to the lower
end of said upright I attach, by a hinge or other suitable device, a wooden arm,
preferably with a T-shaped head. When the said arm is so attached to wooden
upright, the top, or T-end, is free to move on its hinges and can be allowed to
fall into any position, from its normal perpendicular to a horizontal, thus
describing an arc of 90°, more or less. To the top end of said T-piece, I
attach a cord by means of a screw eye, or other suitable device; I then pass the
cord to a pulley wheel which I have fixed to the upper end of wooden upright.
From this pulley wheel the cord passes through a guide at the side of wooden
upright and over, or under, a grooved wheel, then through a second guide and
on to a holder which I fix at any convenient spot.
The method of using elevator is as follows:-The wooden upright is fixed to
the wall in any position as required, with the movable T-piece in its normal
perpendicular position flat against the fixed wooden upright; it is retained in
this position by pulling the cord tight and fixing to holder. The map is then
hung upon the upper free end of movable T-piece by means of hooks and rings.
Suppose that the top of the map so hung is 9 feet from the floor of room and
I wish to inspect the top part of map. The cord is unfastened from its hook,
when the weight of the map will act upon the free end of movable arm and
give it a downward and outward motion, thus lowering the map to any position
that may be required. When the map is finished with, it is only necessary
to haul upon the cord and the arm will assume its normal position and is there
kept by fastening the cord to the holder.

Improvements in Wall Elevators for Library and Office Maps.
I, GERALD STANLEY PHILIP, of 32, Fleet Street, London, E.C., Publisher, 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 follow-
ing statement:-
This invention for improvements in wall elevators for library and office maps
has for its object to provide a ready means whereby a map or the like hung at
DQ77

page_text: any desired height on the wall can be lowered to inspect the map. By this
invention also the map or the like is brought away from the wall so that when
hung over the chimney mantel it will not be liable to damage from the fire when
in its lowered position.
This invention consists in a fixed arm or bracket adapted to be fixed to the
wall, a movable arm hinged at one end to the lower end of the fixed arm or
bracket, and having a hook or hooks at its other end, and a means for fixing the
arm in any desired position.
The accompanying drawing shows one way of carrying out this invention.
The wooden upright a is provided with eyelets by which it can be nailed to
the wall. The wooden arm c is hinged at d to the lower end of the upright a.
The arm c is free to fall from its normal or perpendicular position to the hori-
zontal position and below. Hooks e are provided at the top of the arm c on
its outer face on which maps or the like can be hung.
In order to control the movement of the swinging arm c it is attached at its
upper end to the end of a cord f that passes over the guide pulley g at the upper
end of the upright a, down.through guides i i over the guide pulley h and then
out to any suitable holder.
The map is hung on the hooks e and the arm c is raised by pulling on the
cord and finally fixing it to the holder. To lower the map the cord is released
when the arm will descend by the weight of the map to the required degree and
is then held by belaying the cord.
It will be evident that other means may be employed for controlling the
arm. For example, the hinge may project outwards so that the weight of the
map will tend to hold the arm in its vertical position when once it is forced to
that position the map being lowered by pulling on it in the outward direction.
The hinge may be provided with a tightening device so that it can be clamped
in any desired position.
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 raising and lowering device for maps and the like consisting of an arm
or upright adapted to be fixed to the wall, a movable arm hinged at one end
to the lower end of the fixed upright and having a hook on its face at the upper
end and a means for fixing the arm in any position from the vertical to the
horizontal or below.
2. The improved wall elevator for maps and the like substantially as described
with reference to the drawings.
