Coin Freed Mechanism for Reversing Seats, Lids, Doors, and the like.
We, ALFRED EBENEZER Box, of 10, Albion Street, Everton, Liverpool, Mechanical
Engineer, and HENRY HAVELOCK FARRELL, of 13, Silverdale Avenue, Tuebrook,
Liverpool, Commission Agent, do hereby declare the nature of this invention to
be as follows:
This invention relates to coin freed mechanism for reversing seats, lids, doors,
the lids of water closets, and the like.
When applied to reversing seats, namely those which overbalance, and, when
reversed, lie in an inclined position, their front edge resting against the chair
back, we cause the seat to be retained in this position by a hook or catch, and it
is to release this hook or catch that mechanism according to this invention may
be applied.
Attached to the chair back is the coin reception device, which consists of a
metallic casting provided with a coin slot and a cashbox. This is disposed imme-
diately in rear of the seat catch, and from the latter projects a pawl which enters
the coin slot. When the slot does not contain a coin, and an attempt is made
to turn the seat, the catch moves back slightly but not sufficiently to release the
seat, its complete movement being prevented by the pawl entering a notch in
the coin slot casting. When the slot contains a coin (which is temporarily retained
therein by a spring or weight controlled hook which supports the coin) and the seat
is turned, the catch moves completely out of the way, its pawl coming in contact
When
with and sliding against the coin instead of entering the notch in the slot.
the seat is turned completely over, and sat upon, its rear edge encounters the
spring hook which supports the coin in the slot, and by pressing the hook, releases
the coin, which latter then falls into the cashbox. In order to allow the front
edge of the seat to pass under the catch when the occupier rises and the seat
reverses itself, it becomes necessary to prevent the pawl entering the notch in the
slot, the coin being no longer available for this purpose, and to effect this we
swivel a rod to the seat, which rod, so long as the front edge of the seat is above
the catch, engages with the pawl and holds it clear of the notch. Just, however,
when the seat edge passes the catch, the rod is withdrawn from the pawl, allowing
the latter to enter its notch and so again lock the seat.
Mechanism practically identical with that above described as applied to reversing
or overbalancing seats, may be applied to lids, doors, the lids of water closets,
and the like, whose closing action may be due to a spring or weight.

We, ALFRED EBENEZER BOX, of 10, Albion Street, Everton, Liverpool, Mechanical
Engineer, and HENRY HAVELOCK FARRELL, of 13, Silverdale Avenue, Tuebrook,
Liverpool, Commission Agent, 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 coin freed mechanism for reversing seats, lids, doors,
the lids of water closets, and the like.
When applied to reversing seats, namely those which overbalance, and, when
reversed, lie in an inclined position, their front edge resting against the chair
back, we cause the seat to be retained in this position by a hook or catch, and it
is to release this hook or catch that mechanism according to this invention may
be applied.
The drawing is a side view of a reversing seat-bottom fitted with coin-freed
mechanism according to this invention.
"
Attached to the chair back A is the coin-reception device, which consists of a
metallic casting a provided with a coin-slot b and a cashbox c. This is disposed
immediately in rear of the seat catch d, and from the latter projects a pawl e which
enters the coin-slot b. When the slot b does not contain a coin, and an attempt
is made to turn the seat f upon its pivot f', the catch a moves back slightly but
not sufficient to release the seat, its complete movement being prevented by the
pawl e entering a notch g in the coin-slot casting a. When the slot contains
a coin (shewn in dotted lines and lettered a) which is temporarily retained therein
by the counterweighted hook which supports the coin, and the seat f is turned,
the catch d moves completely out of its path owing to the pawl e coming in contact
with and sliding up the face of the coin a instead of entering the notch g in the
coin-slot. When the seat f is turned over and sat upon, its rear edge encounters
the hook which supports the coin r in the slot b, and by tilting the hook releases
the coin, which latter then falls into the cashbox. In order to allow the edge f of
the seat to pass under the catch d when the occupier rises and the seat reverses
itself, it becomes necessary to prevent the pawl e from entering the notch y in 3
the coin slot, the coin being no longer available for this purpose, and to effect
this we swivel a rod i to the seat, which rod, so long as the edge f of the seat is
above the catch d, engages with the projection e' of the pawl e and holds the
latter clear of the notch. The seat is thus able to push the catch backwards and
re-lock itself. Once, however, the seat edge f³ passes below the catch, the rod i is 3
withdrawn from the projection e¹ of the pawi e. The rod thus prevents the
pawl e from entering the notch g only when the edge f is above the catch d, and is
inoperative when the said edge passes beneath the catch.
Mechanism practically identical with that above described as applied to
reversing or overbalancing seats, may be applied to lids, doors, the lids of water- 4
closets, and the like, whose closing action may be due to a spring or weight.
Our invention is particularly applicable to the reversing seats patented by
Henry H. Farrell under No. 580 of 1896.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we 45
claim is:-
1. As a means of locking a seat or lid retaining catch d, the pawl e swivelled
thereto and entering the coin slot and adapted to enter a notch a in soid clot ----

page_text: unoccupied by a coin, whereby the catch is not allowed sufficient movement to
release the seat or lid,. but which is deflected from such notch by a coin in said
slot, whereby the catch moves sufficiently to release such seat or lid, substantially
as described with reference to the drawing.
2. In combination, a seat or lid retaining catch d, the pawl e swivelled thereto
and entering the coin slot and adapted to enter a notch g in said slot when unoccu-
pied by a coin, whereby the catch is not allowed sufficient movement to release
the seat or lid, and a rod i swivelled to said seat and operating to hold said pawl
free from said notch so long as the seat or lid is free from the catch, whereby in
the closing action the seat or lid may displace the catch and so re-lock itself,
substantially as described with reference to the drawing.
3. As a portion of coin freed mechanism for reversing seats, the hook / disposed
in the path of such reversing seat and adapted to retain a coin within the coin
slot until the revolving edge of said seat encounters and tilts it, whereby such
coin is released, substantially as described with reference to the drawing.
4. The construction, arrangement and disposition of parts forming coin freed
mechanism for seats, lids and the like, combined and operating substantially as
described with reference to the drawing.
