I, WILLIAM PARKER GIBSON of 4 Queen Victoria Street in the City of London
Engineer, do hereby declare tho nature of this invention to be as follows :-
This invention relates to that class of hydraulic or other lifts in which the cage to
be lifted and lowered is carried upon a rope or chain which is wound or unwound
from a drum or barrel said drum or barrel being operated by hydraulic or other
power.
According to my invention I propose to mount a cross-head upon the end of the
ram or piston rod outside of the cylinder, said cross-head carrying an axle upon either
end of which are keyed rope or chain wheels. Around one of the wheels is coiled a
rope or chain, one end thereof being secured thereto and the other end being attached
to an eye bolt or other fixed point. If the ram or piston be raised, the strain on said
rope will cause the wheel to be revolved and with it the axlo and the second wheel
attached thereto, from whence passes a rope or chain to a third wheel or drum attached
to the axle of the main or cage drum so that any upward motion of the piston or ram
will cause the cage to be lifted while the weight of the cage when descending causos
its drum with the attached axle and third wheel or drum to be revolved, thereby
turning the second wheel and through its axle the first wheel upon which what may
be termed the driving rope or chain is coiled.
It will be evident that by proportioning the diameter of the wheels and drums any
requisite amount of cage travel may be obtained for any given piston or ram travel
and also that the apparatus may be operated by high or low pressure, hydraulic,
steam, or other power.

1, WILLIAM PARKER GIBSON of 4 Queen Victoria Street in the City of London,
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 relates to that class of hydraulic or other elevators or lifts in which
the cage to be lifted or lowered is carried upon a rope or chain which is wound or
unwound from a drum or barrel, said drum or barrel being operated by hydraulic or
other power.
In order that my invention may be fully understood by others skilled in the art to
which it appertains, reference is made to the accompanying drawings, in which :-
Figure 1 represents a side elevation, and Figure 2 a front elevation, partially in
section.
According to my invention, I propose to mount a cross-head A, upon the end of the
ram or piston rod B, and outside of the cylinder C, said cross-head carrying an axle a,
upon either end of which are keyed rope or chain wheels D and E. Around the
wheel D is coiled a rope or chain d, one end thereof being secured thereto and the
other end being attached to an eye bolt or other fixed point b. If the ram or piston B
be raised the strain on said rope d will cause the wheel D to be revolved and with it
the axle a and the wheel E attached thereto. From wheel E passes a rope or chain e
to a third wheel or drum F, which is attached to the axle f of the inain or cage
drum G. Around this drum G is wound the cage-rope, which is not shown, and
which passes up to the top of the building over the usual pulley and down to the cage
as is well understood.
Any upward movement of the piston or ram B will cause the rope or chain to be
wound upon the drum G, and the cage accordingly to be lifted, while the weight of
the piston and connected parts is sufficient to cause them to descend when the pressure
is removed, the weight of the cage when descending causing the drum G, with the
attached axle and wheel or drum F, to be revolved, thereby turning the wheel E,
and through axle a, the wheel D, upon which what may be termed the "driving rope
or "chain" d is coiled.
It will be evident that by proportioning the diameter of the wheels and drums any
requisite amount of cage-travel may be obtained for any given piston or ram travel,
and also that the apparatus may be operated by high or low pressure hydraulic, steam,
or other power, and this renders the invention particularly useful for what are known
as dinner or "light lifts," or "elevators," where a quick cage travel is desired.
"
"
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an elevator or lift, the combination with a cylinder, its piston and piston-rod,
of a pair of wheels mounted in bearings upon the piston-rod, and a revoluble drum,

page_text: one of the wheels having a chain or rope connected thereto and to a fixed point, and
the other wheel having a chain or rope connected to it and to the revoluble drum, and
connections between the latter and a cage, whereby when the piston is moved the pair
of wheels will be revolved to thereby revolve said drum to actuate the cage substantially
as described.
2. In an elevator or lift, the combination, with a cylinder, its piston and piston-rod,
of a pair of wheels of different diameters mounted in bearings to travel with the
movement of the piston, a drum adapted to be rotated by the rotation of said wheels,
two independent chains or ropes, one for each of said wheels, the end of one of the
said chains or ropes connected to a fixed point, and the other of said chains or ropes
connected to and wound upon said drum, and connections between the latter and a
cage for actuating it, substantially as described.
3. In an elevator or lift, the combination, with the cylinder, its piston and piston-
rod, of wheels D and E secured upon a shaft a and mounted to turn in bearings on
the piston-rod, drum F and cage-drum G mounted to revolve together in fixed
bearings, independent chains d, e, one secured to the wheel D and to a fixed point and
adapted to be wound on and unwound from said wheel, and the other secured to the
wheel E and to the drum F, and adapted to be wound on and unwound from said
wheel and drum, substantially as described.
4. The combination of the cylinder provided with a bearing for a shaft and drums
mounted on said shaft upon opposite sides of said bearing, the piston and its rod, a
bearing for a shaft a secured to the end of the piston-rod and arranged parallel with
the first-named bearing and shaft, wheels secured to said shaft a, one upon opposite
sides of the bearing, a rope or chain wound upon one of said wheels and secured to a
fixed point, and a second rope or chain wound upon the other of said wheels and
connected with one of said drums, substantially as described.
