Improvements in the Construction of Apparatus for Testing Physical
Strength or Weighing, and Simultaneously Moving and Dis-
playing Advertisements or Delivering Articles, the whole being
Unlocked for Operation by the Action of an Introduced Coin.
I JAMES MORRIS O'KELLY of 12 Compton Street Soho London in the county of
Middlesex, Mechanic do hereby declare the nature of this invention to be as
follows:-
My invention relates to the apparatus described in my provisional specification
dated the 11th day of March 1887 and numbered 3730, and has for its object the
combining with that invention of a weighing apparatus, which is actuated in a similar
manner to that therein described and which when actuated shall produce similar
results. I would not however have it understood that the weighing apparatus can
only be worked in the combination as described above, as it may also be employed
separately when desired.
The mechanism which I employ for effecting the weighing of any person or article,
is generally similar to that described in my previous specification, and cannot be put
into operation until a coin of suitable weight and size has been placed in a slot
provided to receive it, and from which, after performing the function required of it, it
cannot be withdrawn from the apparatus.
It consists of a rocking lever, having at one end a suitable receptacle for the coin,
and at the other a rack of teeth, which lock into a corresponding suding rack attached
to a bar or chain. to one end of which the weighing platform is attached and to the
other end a strong spiral spring or weight.
So long as the teeth on the above described locking lever are locked into the
corresponding teeth, no action of the apparatus can take place, but as soon as the coin
reaches the receptacle in the opposite end of the lever, it overbalances it, and leaves
all free for action so soon as the object to be weighed is placed on the platform. A
guard for the open end of the coin receiver is suitably secured to any convenient
moving part, which holds the coin in the receiver until the apparatus is brought into

page_text: action and then allows it to fall into any convenient receptacle, when the lever resumes
its normal position, ready to relock the apparatus after action.
A rack fitted with a pinion, to the spindle of which a pointer is secured for
indicating the weight to be registered is secured to some moving part of the apparatus,
or the weight may be registered in some other convenient manner.
A similar device to that described in my provisional specification above referred to,
may be employed in connection with the operating of this machine, by which
advertisements may be displayed or changed, or articles stored in the machine may be
delivered.
Suitable devices may be employed to stop back action, and to close the orifice when
the articles are exhausted, as well as to indicate the number of articles delivered.

I JAMES MORRIS O'KELLY of 12 Compton Street Soho London in the county of
Middlesex, Mechanic 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 :-
The invention relates to the apparatus described in my Patent application dated
11th day of March 1887 and numbered 3730, and has for its object the combining
with the apparatus therein described, of a weighing mechanism which is actuated in a
similar manner, and which shall be capable of producing similar results when actuated.
1 would not however have it understood that the weighing apparatus can only be
operated in the combination above named; as it may be employed separately when
desired.
The mechanism which 1 employ is normally at rest and is so secured; and can only
be unlocked for operation by the introduction of a coin of suitable size and weight, by
means of a slot provided to receive it; the coin falls into a receptacle provided, at one
end of a balanced lever, and by its weight lifts the locking gear at the opposite end of
the lever and frees the mechanism. The moving parts of the apparatus (thus freed)
are fitted at any convenient point or points with teeth or ratchets, which are arranged
to gear with ratchet wheels to which drums are attached, for carrying advertisements,
or for regulating the delivery of articles. A rack is also fitted, which gears into a
pinion, to the spindle of which a pointer is secured, for indicating the weight applied,
in the usual way.
Referring now to the accompanying drawings Figure 1 is a front elevation of the
apparatus. Figure 2 is a side elevation partly in section. Figures 3 and 4 show a
front and side view of an alternative arrangement of mechanism for weighing.
Figures 5. 6 and 7 are details of the locking and unlocking gear, Figures 8 and 9
show the apparatus for delivering articles, and Figures 10 and 11 the apparatus for
displaying or changing advertisements all in detail.
Similar letters refer to similar parts throughout.
The case of the apparatus is represented by the letter A, the platform upon which
the person or article to be weighed is placed by the letter B and the spring upon
which the strain or force is received by C. This strain is transmitted by means of
levers chains or bars in any convenient manner. The arrangement shown in figure 2
and in detail figures 5. 6 and 7 consists of a bracket D attached to the platform B, a
lever E working in a bracket F attached to the case A, one end of which is connected
to D by a pin, the other end being formed as a quadrant which works into the
toothed pulley G to which the chain H is secured, and which works in the bracket I

page_text: as shown. The chain H is carried over the pulleys G₁ and 2 which are carried by the
bracket J which is secured to A, and so through the spring to the collar K to which
it is secured, and by means of which the strain resulting from the weight placed upon B
is transmitted to C. The indicating gear is represented by the letter L. The catch by
means of which the drum M which regulates the delivery of articles is actuated is
lettered N, and O is the bar which actuates the drum P to which the advertisements
are attached. The locking gear is arranged between the pulleys G¹ and 2 and is
described hereinafter.
Figures 3 and 4 show an alternative arrangement in which a second lever E¹ takes
the place of the pulley G, and is connected with E by a pin working in an elongated
slot; the opposite end of E¹ is connected direct with the bar H which passes through
the spring and transmits the strain resulting from the weight placed upon B by
means of the collar K directly to it. The bar His extended as shown and actuates
the indicating gear L: the rod or bar N actuates the drum M, and the bar O actuates
the drum P. Pulleys G¹ and 2 are arranged to gear with a rack cut in H and aro
connected by a chain as shown, between which the locking gear is arranged as herein-
after described.
The mechanism by which the apparatus is held locked until a coin of suitable size
and weight has been inserted in a slot provided for the purpose in the case A is shown
in figures 3. 4. 5. 6 and 7. It consists of a balanced lever a working upon a fulcrum b,
at one end a receptacle c is provided for the coin into which it is conducted by suitable
formed shoots from the slot above referred to: at the opposite end of a a stop or
clutch e is provided, and a corresponding clutch f is secured to the chain H. These
clutches ef are arranged with teeth or notches as shown, their object being to effect
the locking of the apparatus immediately sufficient back action has taken place to enable
any of the teeth to lock together, thus preventing the repeated use of the apparatus
when only a slight reaction has taken place instead of waiting until it has entirely
recovered itself as in machines at present in use. The stop e is provided with a guide
plate g which is secured to the case A by any convenient arrangement, by which it is
held in position and receives and counteracts any weight applied at B so long as there
is no coin in the receptacle c of the lever a. When a coin is inserted as above
described and is received in c it overbalances a and lifts the opposite end to which e is
attached through the guide g clear off thus liberating the mechanism for action. A
shield plate is attached to the chain H which in its normal position covers the
aperture in cand prevents the coin from falling out, until the apparatus is set in
motion, when it is carried by the chain H away from the aperture and the coin falls
into any suitable receptacle, thus liberating the lever a which is then able to again
assume its normal position, upon the weight upon B being removed.
A special catch designed to secure effectual and immediate action of the locking
gear is shown in figures 6 and 7, it consists of a palli which in its normal. position
rests against the lever a a second pall j pivoted at and a rack attached by means of
the arms ¹ to H as shown. Its action is as follows, immediately the weight of the
coin in coverbalances the lever a the pall which is pivoted at falls under it and
rests against a stop provided for the purpose of holding it in the desired position. As
the apparatus is operated the pall; rides over the teeth of the rack 7, but immediately
the return action commences one of the teeth on engages with the pall ; which
raises from below the lever a which immediately falls and by the action of the
clutches ef the apparatus is again locked as above described.
The mechanism by means of which. articles are delivered when the apparatus is set
in motion is shown in figure 2 as well as in the enlarged views 8 and 9. A receptacle Q
for the articles is fitted inside the case A as shown and at its lower end the drum M
which is recessed or corrugated, is arranged to revolve in bearings in brackets which
are secured to case A as shown in figure 2. To the ends of the drum M ratchet
wheels N¹ are secured and into one of these the catch N shown in figure 8 is arranged
to gear, turning the drum M partly round each time the apparatus is actuated, this
catch is pivoted with a stop which moves the drum in one direction but rides over the
teeth of N¹ in the return action. As the drum moves it carries with it one of the articles

page_text: stored in and releases it below, when it is carried to the outside of the case by the
channel or guide R, and may be taken by the operator.
The general arrangement of the mechanism for displaying and changing advertise-
ments is similar to that above described in respect of the delivery of articles, it is
shown in figure 2, and to an enlarged scale in figures 10 and 11. The drum P to
which the advertisements are attached is arranged to revolve in bearings secured in
the case A and to it, ratchet or toothed wheels are secured. The rod O is provided
with a ratchet or catch similar that shown at N figure 8, which moves the drum P in
one direction each time the apparatus is actuated, and which rides over the teeth of
the wheel O in the return action. As the drum moves it carries with it the
advertisements; causing a different one to be displayed each time the apparatus is
actuated.
Figures 1 and 2 show a convenient arrangement of combining the various strength
testing apparatus described in my Patent specification No. 3730 with the weighing
apparatus herein described.
It will be seen from the foregoing description that the apparatus is normally at rest
and is so held by the locking gear. When a coin of suitable size and weight is
introduced at X and conducted by a shoot provided for the purpose to the locking and
unlocking gear, the mechanism is released and may be operated by any weight placed
upon B. The weight is at once registered upon the dial Y an article is delivered at R
and an advertisement is displayed at Z.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
•
1. The combination with the weighing apparatus of the mechanism for delivering
articles displaying advertisements substantially as described and shown.
and
or
2. The employment of a double pall i,j with rack 1 in combination with the balanced
lever a substantially as and for the purpose described and shown.
3. The combination of various apparatus for weighing and strength testing in one
case, so arranged that each one separately shall be capable of actuating the mechanism
for delivering articles for changing advertisements substantially as described.
