PROVISIONAL SPECIFICATION.
Apparatus for Lifting Goods that have to be Loaded on Vehioles,
Stacked, or Placed in Raised Positions.
I, GASTON CÉSAR CABANIS of 1 Boulevard St. Denis, Paris, France, Engineer, do
hereby declare the nature of this invention to be as follows:
This invention.consists of apparatus actuated by the weight of men for lifting goods
that have to be loaded on wagons or other vehicles or stacked or placed in raised
positions.
The apparatus is mainly composed of four uprights forming a rectangular frame in
which two horizontal platforms move up and down in opposite directions, these
platforms being connected together by ropes or other suitable connectors so that when
the one rises the other descends and vice versa. The platforms have rollers to bear
against vertical rails on the uprights.
The upper platform is the goods platform and the lower one the mens' platform;
In the normal
this projects beyond the uprights and there are steps leading up to it.
position the goods platform is at such a height that the men can readily lift goods on
it when standing on the ground; the mens platform is immediately below the goods
platform. There is a lever catch or device for retaining the mens' platform at its
highest position and another catch for retaining it at its lowest position. There are
handles on the uprights to assist the men in mounting the platform and also to enable
them when on the platform to exert a force downwards when the retaining catch is
released.
When the goods platform is loaded the men mount on to the other platform, then
one of them releases the retaining catch, and the mens' platform being thus freed their
weight, which must exceed that of the goods causes the platform to descend and the
goods platform to rise. When the mens' platform reaches the bottom it is caught by
the catch provided for the purpose and therefore the goods platform cannot descend
after the men have stepped off.
As the distance to which the goods platform rises is limited by the height to which
the men can lift the goods on to it I sometimes provide an inclined plane between two
of the uprights so as to facilitate the loading.
The goods are removed from the raised platform and placed on the vehicle or stacked
or placed in the required position.as the case may be; then the lower catch is released
and as the empty goods platform is somewhat heavier than the empty mens' platform
it descends to its normal position ready to receive a fresh load, the mens' platform
rising at the same time.
For goods which cannot be lifted on to the platform I modify the apparatus so as to
allow the goods platform to descend to the ground; the goods can therefore be rolled
or slid on to it. With this view I make the mens' platform to travel outside instead
of inside the uprights, the goods platform.travelling inside as before; they are thus
able to pass each other.

Apparatus for Lifting Goods that have to be Loaded on Vehicles,
Stacked, or Placed in Raised Positions.
. I, GASTON CÉSAR CABANIS of 1 Boulevard St. Denis, Paris, France, Engineer,
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 consists of apparatus actuated by the weight of men for lifting goods
that have to be loaded on wagons or other vehicles or stacked or placed in raised
positions.
The apparatus is mainly composed of four uprights forming a rectangular frame in
or on which two corresponding platforms move up and down in opposite directions,
these platforms being connected together by ropes or other suitable connectors so that
when the one rises the other descends and rice versa.
The annexed drawings will serve to illustrate my invention. Figure 1 is a side
elevation, Figure 2 an end elevation and Figure 3 a plan of one modification.
Figures 4 and 5 represent another modification."
Referring first to Figures 1 to 4 A, B, C, D, are uprights carrying rails or guides a.
E, F, G, H, I, J, K, L are horizontal beams connecting the four uprights A, B, C, D.
M is the goods platform and N the men's platform. 00 are grooved pullies over
which the four cords or other connectors Z pass. PP are cast iron supports or
brackets at the four corners of the platform M. QQ are supports at the corners
of the platform N. R R are guide rollers on the supports P and Q to guide the
platforms M and N in their up and down movements. SS are steps to enable the inen
to mount the platform N. T is a lever catch for holding and releasing the platform N.
U is a pedal catch for holding and releasing this same platform V is a lever for
releasing the lever catch T and consequently the platform N. W W are handles to
assist the men in mounting the steps and allowing them when on the platform N to
exert a force downwards upon this platform when the retaining catch is released.
XX are stops which limit the upward movement of the platform N. Y Y are stops
which limit the downward movement of the platform M. Z Z are the cords passing
over the pullies O one of their ends being fixed to the platform M and the other to the
platform N.
The apparatus being in the position indicated in the drawings the men place the
luggage to be lifted on the platform M. They mount on to the platform N by means
of the steps S. Then one of them releases the retaining catch T by pulling on the end
of the lever B. The platform N being thus freed and being with the weight of the
men heavier than the platform M descends until it is engaged by the pedal catch U.
The platform M has meanwhile ascended to a height equal to the downward travel of
the platform N. As the distance to which the goods platform M rises is limited by the
height to which the men can lift the goods on to it I sometimes provide an inclined
plane between the two uprights A and B so as to facilitate the loading.
The platform N having after its downward movement been secured by the pedal
catch the men can step off and the goods are then removed by a man or men above
from the raised platform and loaded on the vehicle or stacked or placed in the required
position as the case may be. Then the lower catch U is released and as the empty
goods platform is somewhat heavier than the men's platform it descends to its normal
position ready to receive a fresh load, the men's platform rising at the same time.
The men's platform N on being caught by the pedal catch Ŭ can be made to strike
a bell so as to let the men know they can step off.
When the goods platform M reaches its highest position it can be engaged by three
or other number of catches fixed on the uprights, these catches being connected
together and to the lower catch U so that by pressing on the latter the top catches can
be freed and allow the goods platform to descend.

page_text: Instead of the various catches above described I can employ two ratchet wheels on
each of the shafts of the pullies O. These two wheels have their teeth in the reverse
directions so that the platforms can be stopped at any point of their travel whether
loaded or empty. Instead of the horizontal beams E, F, G, H which connect the
uprights A, B, C, D I can connect the said uprights to the lower frame by four braces

or stays and thereby facilitate the loading and unloading.
facilitate the passage of the apparatus under low arches or bridges the uprights can be
hinged at about two-thirds of their height.
The goods platform can be constructed to receive a weighing machine or the
weighing machine itself may serve as the platform so that the goods can be weighed
and loaded at the same time.
The apparatus can be made either as a fixed structure or mounted on pivots or rails
according to circumstances.
For goods which cannot conveniently be lifted on to the platform I modify the
apparatus so as to allow the platform to descend to the ground. The goods can there-
fore be rolled or slid on to it. Figures 4 and 5 already referred to illustrate this
modification. The goods platform M runs as before up and down the guide rails a
while the men's platform runs up and down rails or guides 6 outside the frame; the
In order to facilitate the work
two platforms are thus able to pass each other.
I fix on the uprights two horizontal bars c and d one at the upper part and the other
midway of the travel of the men's platform; the men take hold of these bars with
their hands.
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 :-
The apparatus constructed and working substantially as herein before described and
represented in the annexed drawings for lifting goods that have to be loaded on
vehicles, stacked or placed in raised positions.
