Exerted in Lifting a Weight or its Equivalent.
WILLIAM SAMUEL OLIVER, Albert House St. Pauls Road Canonbury N. Engineer,
do hereby declare the nature of my invention for MEANS OR APPLIANCES FOR
AUTOMATICALLY INDICATING THE POWER EXERTED IN LIFTING A WEIGHT OR ITS
EQUIVALENT to be as follows:-
My invention consists in the application of electricity to a machine for indicating
the power exerted in lifting a weight or its equivalent so that the act of placing a coin
or the like, in the apparatus will cause the power exerted to be indicated on a dial or
the like, or will mark or print the same upon a card or the like. To carry out my
invention I use a lifting machine constructed upon any well known plan or otherwise
& combine with it my special apparatus-On a coin being dropped into the machine
it closes an electric circuit either directly by itself acting as a metallic connection
between two portions of the circuit or indirectly by moving by its weight or impetus
one metallic contact against another-Preferably I adopt the following arrangements
to produce this result-In the former case the coin falls down a shoot & lies upon or
between two plates forming the terminals of the divided portion of wire & thus forms
the connection between the two-In the latter the coin falls upon two pistons or
springs which are depressed & either comes in contact with other pieces of metal or
dip into a cup of mercury. In either case there is an arrangement for getting rid of
the coin when the passage of the current is not further necessary-For this purpose I
preferably place the metals aforesaid upon a swinging platform which moves & drops
the coin when a pin or other device upon the mechanism comes into contact with a lever
or crank attached to it, or releases a catch which holds it up. By either of the afore-
said methods a current is allowed to pass through an electric magnet placed in the
circuit & attract to it an armature withdrawing it from its position of rest, this
armature having up to this moment of the coin being dropped in acted as a stop or
bolt locking the apparatus & preventing it being actuated by any power exerted upon it.
Instead of the above the armature may be used to connect two portions of the
mechanism so as to communicate motion from one to another or the electro magnet

page_text: attached to one portion of the mechanism may be used to attract to itself the armature
attached to another portion of the mechanism so that any movement given to the one
is transmitted to the other.
In the usual form of lifting machine the locking aforesaid is preferably effected by
an armature engaging a projection upon the cylinder carrying the spring or upon the
rod or other device which carries the rack moving the pinion upon which the index
hand is attached-I may also in some cases utilise the weight or momentum of the
coin to either introduce the battery plates into the exciting liquid or raise the liquid
so as to cover the plates-Instead of the usual method of moveable handles I some-
times construct my machine with fixed handles & a moveable platform as in the
ordinary type of weighing machine, which is depressed by the feet, & thus we
ascertain the total effective force of the individual, it being the combination of his
weight & lifting capacity. Instead of the above I sometimes use the following
arrangement, the index hand which in the usual form of machine is visible is here
contained within the body of the machine & carries a projecting stop. An axis
bearing an index hand which appears upon the dial bears upon it a pulley round
which passes a cord attached to a weight or spring or a spring is attached directly or
by a train of wheels to the aforesaid axis. The index hand thus tends to revolve in
one direction but is prevented from doing so by a catch which is engaged by a hooking
lever or other device & which latter either forms or is connected with the armature of
an electro magnet. On the circuit being closed in the manner aforesaid by the coin
it is released & will revolve until arrested by the stop upon the other index hand &
thus indicate upon the dial the position of the latter. Motion may also be com-
municated to, it by an electro motor. There is an arrangement for cutting off the
current when the indicating hand begins its retrograde movement, preferably for this
purpose I use a wheel with hinged cogs engaging a lever or crank connected with the
moving platform upon which the coin falls. When I make the machine to deliver
cards either alone or in combination with indicating on a dial I fix preferably the
pinion which engages the rack moving the inking & delivering arrangement upon
the axis carrying the indicating hand. Or I use any of the above methods in
combination.

I WILLIAM SAMUEL OLIVER, Albert House, St. Pauls Road, Canonbury N.
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 :-
My Invention consists in the application of electricity to a machine for indicating
the power exerted in lifting a weight or its equivalent so that the act of placing a coin
or the like in the apparatus will cause the power exerted to be indicated on a dial. To
carry out my Invention I use a lifting machine constructed upon any well known
plan or otherwise and combine with it my special apparatus. On a coin being dropped
into the machine it closes an electric circuit either directly by itself acting as a
metallic connection between two portions of the circuit or indirectly by moving by its
weight or impetus one metallic contact against another. Preferably I adopt the
following arrangement to produce this result.
The coin falls down a shoot A and lies upon two plates B, C, forming the terminals
of the divided portions of wire D, E, and thus forms the connection between them.
I provide an arrangement for getting rid of the coin when the passage of the
current is not further necessary.
For this purpose I place the metals aforesaid upon a swinging platform F, see the
Figure, which moves and drops the coin into the box F¹ when a pin or other device G
upon the lift mechanism H comes into contact on the return of the handle with a
lever or catch I which holds it up. By the aforesaid method a current is allowed to
pass through an electro-magnet J placed in the circuit and attract to it an armature L
withdrawing it from its position of rest, this armature having up to this moment of
the coin being dropped in acted as a stop or bolt by its point M and bar N locking the
lift apparatus and handles P to prevent them being actuated.
Instead of the usual method of movable handles I sometimes construct my machine
with fixed handle and a movable platform as in the ordinary type of weighing machine
which is depressed by the feet and thus is ascertained the total effective force of the
individual, it being the combination of his weight and likewise lifting capacity.
U is the connecting pieces between the lift rod V and dial rod W for operating the
dial. X, X, are the terminals, Y is the spring encircling the lift rod V. The electric
circuit is completed when the handle P is pulled sliding plate Z then coming into
contact with the arm a, which plate Z and arm a have conducting wires bc, onę
leading to the electro magnet and the other to the battery d.

page_text: The pull lever V has a small amount of free play, so that the spring Y is not acted
upon at the first portion of its movement, so that the arm a and plate Z are in contact,
the circuit being thus completed and the armature L attracted to the magnets for
unlocking the bolt M from over the arm N.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
:-
1. The means and appliances for automatically indicating the power exerted for
lifting a weight or its equivalent as herein set forth.
2. The means of and apparatus for making and breaking electrical contact as herein
set forth.
