I CHARLES FREDERICK ARCHER of 30, Kirby Street, Hatton Garden, Middlesex,
Engineer, do hereby declare the nature of my said invention to be as follows:-
This invention relates to a novel arrangement or combination of three cylinders
and rams and a fuzee or equivalent drum also chain and chain wheels, the whole
acting in unison and constituting hydraulic lift mechanism in or by which the power
of the pressure cylinder is exerted by its rain direct upon a chain connected to a fuzee
or equivalent drum, said fuzee being on a shaft carrying wheels on which other chains
attached to the head of a compensating or an accumulator ram of the second cylinder
can be wound when the fuzee and power ram is in operation the power cylinder being
distinct, the accumulator cylinder and the lift cylinder alone being in communi-
cation by a pipe for the to and fro travel of the liquid as the lift is raised or
lowered.
The accumulator cylinder is preferably larger than that of the lift cylinder so that
its ram has a travel proportionately less to that of the lift ram.
The power cylinder is very small and its ram has a short motion the race or chain
groove of the fuzee being rapid so that the power exerted is conveyed to the accumulator
ram by the drum chains for drawing said ram down and exerting the power of its pull
the lift.
upon
I have referred to a fusee or its equivalent, said equivalent may be a pinion mounted
eccentrically or otherwise on a shaft having the gear or chain drums between it and
the accumulator motion said pinion taking its action from a rack attached to the
power ram.
If the pinion be fitted eccentrically the rack as raised would move up and down at
an angle controlled by rollers.

1, CHARLES FREDERICK ARCHER, of 30 Kirby Street, Hatton Garden, Middlesex,
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 a novel arrangement or combination of three cylinders
and rams and a fuzee or equivalent drum also chains and chain wheels, the whole
acting in unison and constituting hydraulic lift mechanism the object being from the
different capacities of the three cylinders that the fluid used in the lift cylinder can
flow back into the compensating cylinder for constant reuse, a small quantity only of
Huid escaping from the power cylinder at each action of the lift.
Figures 1 and 1ª show side elevations of so much of a hydraulic lift mechanism as
will enable one plan or arrangement of my Invention to be understood. A is the
pressure or power cylinder with its ram B provided with chains C connected to
drums D, D, mounted on a cross shaft E carrying eccentric or fusee wheels F, F, the
chains I of which are connected to the head of the balancing ram K, the cylinder L
of which is in connection by a pipe N with the lift cylinder M for operating the
lift P.
Figure 2 shows a modified arrangement of the fusee and drum gear.
A is the pressure cylinder as before the power of which is exerted by its ram B
direct upon a chain C wrapped round a fuzee D said fuzee D being on a shaft E which
carries drums F. G, and chains H, I, attached to said drums F. G, and also to the head J
of a balancing ram K of the second cylinder L, on to which drums F. G, said
chains H. I, can be wound, when the fuzee D, and power ram B is in operation the
power cylinder A being distinct from the compensating cylinder L.
The accumulator cylinder L and the lift cylinder M are in communication by a
pipe N for the to and fro travel of the liquid as the lift P is raised or lowered.
The accumulator cylinder L is preferably larger than the lift cylinder M so that its
rain K has a travel proportionately less than the lift ram P the pressure cylinder A is
very small and its ram B has a short motion the race of the chain groove of the
fuzee D being rapid so that the power exerted is conveyed to the balancing ram K
by the drum chains H. I, for drawing the said ram K down and exerting the power
of its pull upon the lift P.
Qis the valve by which the liquid is admitted to the pressure cylinder A by the
feed tube R, the tube S being the exhaust.
I have referred to a fuzee or its equivalent, said equivalent may be a pinion T, see
Figure 3, mounted eccentrically or otherwise on a shaft E having other gear U or
chain drums F. G, between it and the accumulator motion said pinion taking its action
from a rack V attached to the power ram B.
If the pinion T be fitted eccentrically the rack V as raised would move up and down
at an angle controlled by rollers W.

page_text: The eccentrically fitted pinion T may be dispensed with and an eccentric cam ✗
may have the pressure ram chain C attached for operating the balancing ram K
through the chains H. I. drums F. G, and pinion Y and gear wheel Z or the shaft E
as shown at Figure 4.
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. The combination of three cylinders and rams and their appurtenances, all
arranged substantially as shown in the annexed drawings as and for the purpose
described.
2. In connection with three cylinder hydraulic mechanism, the fuzee or eccentric
appliances between the pressure cylinder A and the compensating cylinder L for the
purpose described.
