"
(Void by reason of the Patentee having neglected to file a Specification in
pursuance of the conditions of the Letters Patent.)
PROVISIONAL SPECIFICATION left by the said Heinrich Reichardt at the
Office of the Commissioners of Patents on the 22nd June 1883.
HEINRICH REICHARDT of Haverstock Hill, in the County of Middlesex
"IMPROVEMENTS IN APPARATUS FOR RAISING AND LOWERING
"
My Invention relating to improvements in apparatus for raising and lowering
has reference to an apparatus applicable as a fire escape, a lift for warehousos,
hotels, restaurants and other similar purposes, for raising and lowering signal
lamps on railways and in other places, also for use by masons and others for
performing building and decorating and other like operations, in place of the
usual scaffolding, also for reconnoitring purposes in military campaigns, also for
raising water from wells, and generally wherever it is required to elevate or lower
any objects.
In carrying out my Invention as applied for example to the construction of a
fire escape, I employ a number of series of jointed levers, each of which series
consists of two sets of levers each lever of each set being jointed to its neighbour
of the same set at each end, whilst the two levers of each set are pivotted together
at their centre. To the several series of levers are attached plates, platforms or
skeleton frames at the point where the levers are pivotted together; one of these
plates, platforms, or frames say for example the bottom one, is provided with means,
such for example as a screw, eccentric wheel, windlass or any equivalent mechanism
by operating which the particular plate, platform or frame to which it is applied
is moved up or down and thence motion is communicated by the expansion or
contraction of the levers to the upper or other plates, platforms or frames which

page_text: are thereby separated to a greater distance apart or brought into closer proximity
or contact, whereby a person or object stationed or placed on the uppermost plate,
platform, or frame is raised or lowered as the case may be. The uppermost plate,
platform or frame may be suitably enclosed, and a ladder bridge or stago may be
provided at the top for facilitating egress from or ingress into a house or building.
Suitable guides aro by preference provided to ensure the proper and steady
movement of the several plates, platforms, or frames, and means such for example
as cross bars and pins applied to the lovers may also be employed for securing the
plates, platforms, or frames at any desired height. Weights or springs may also
be applied to the lowermost levers for facilitating and assisting the movement.
This apparatus may be secured to a suitable frame-work or platforın mounted on
wheels for the facility of moving it from place to place. This platform may be
provided with struts or supports for attachment at their upper ends to the
apparatus so as to secure greater stability.
When the apparatus is intended to be used as a lift for warehouses, hotels,
restaurants, and other like purposes, it is constructed in a similar manner with the
exception that it is not always necessary that it should be portable. When applied
on railways for example for raising and lowering signal lamps, one series of levers
attached to-a-support. will be sufficient to accomplish the object.
In the case of apparatus intended for use by masons and others for performing
building and decorating and other like operations, also for reconnoitring purposes
in military campaigns, and for raising water from wells the construction is similar
to that of the fire escape herein before described the dimensions and details of
arrangement only being varied according to the particular purpose to which it is to
be applied.
