I WILLIAM HENRY STEEL Engineer, of 116 Clapham Park Road London S.W.
do hereby declare the nature of this invention to be as follows:-
In which a series of cars or cages, are kept in continuous motion, ascending on
one side and descending on the other, by means of two endless chains set opposite
each other, and passing over four sproggett or pitch wheels; two at top and two at
bottom of elevator, the cars or cages are slung by a pin or bolt in front of chains
at or near the top and bottom of the said cars or cages the same being controlled in
passing over the top and bottom centres of elevator, by means of one chain being
elevated or placed a suitable distance above the other, so that the highest chain
controlls the top of car and the lower chain the bottom of same the cars or cages
being connected to the said chains by a pin or bolt aforesaid.

WILLIAM HENRY STEEL, Engineer, 116" Park Road Clapham London, S.W.
do hereby declare the nature of my invention for AN IMPROVEMENT IN DOUBLE
CHAIN ELEVATORS OR LIFTS SUITABLE FOR PASSENGERS AND GOODS" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
The object of this invention is an improvement in "Double chain continuous
elevators or lifts" in which a series of cars or cages, suitable for receiving
passengers or goods, are kept in continuous motion, ascending on one side and
descending on the other, by means of two endless chains set opposite each other
and passing over four sproggett or chain wheels; two at top and two at bottom of
elevator.
·
The cars or cages are slung by a pin or bolt in front of chains, at or near the top
and bottom of the said cars or cages, the same being controlled in passing over
centres at top and bottom of elevator, by means of one chain being elevated or
placed a suitable distance above the other, so that the highest chain controlls the
top of car or cage, and the lower chain the bottom of same, the cars or cages being
connected to the said chains by a pin or bolt as before mentioned.
Figure 1. in drawings is a front elevation and Figure 2. is a side elevation of an
elevator or lift constructed in this manner. A. A and B, B¹ are sproggett or chain
wheels the projections or teeth of which engage with the links of the chains C
and D to which are connected the cars or cages E E E E³ by means of the pins F
which sustain the said cars or cages in ascending and descending and in passing
over and under centres at top and bottom of elevator.
The shaft or spindle of chain wheels A¹ B' at top or A. B. at bottom of elevator
can be constructed so that suitable gearing may be coupled, in order that the chain
wheels may transmit motion to the endless chains carrying the cars or cages as
before said, the gearing G. being so arranged as to drive the two endless chains at
uniform speed, actuated by any motive power, suitably controlled.
Having now particularly described the nature of my said Invention and the
manner of performing the same I declare that what I claim is
That by elevating one endless chain a suitable distance above the other, so that
the highest chain controlls top of cars, and the lower chain the bottom of same
in passing over and under centres at top and bottom of elevator, as described in
drawings.
