I GEORGE WILLIAMSON of 9 Nursery Mount Road Hunslet Leeds in the County
of York Engineer do hereby declare the nature of the invention to be as follows:-
This invention relates to providing new or improved means for enabling the
fastenings of Turnstiles, Doors, Gates, Barriers or Platforms to be released and for
Collecting the Fee charged for passing through or for using the same, this I effect
by arranging the fastenings of the turnstile or its equivalent so that when a proper
coin or token is placed in a receptical provided for the purpose, it will form a filling
piece or key and enable the user to undo the fastenings by the ordinary act of pushing
open the door or turnstile (or in the case of a platform by standing upon it) without
any other act being necessary.
I will describe my invention as applied to a turnstile or rotating door from which
its application to analogous uses will be understood.
When the invention is applied to a turnstile or rotating door I connect a pawl
arranged to engage with the teeth of a circular rack in the top or the bottom of
frame in the ordinary way to ensure the motion being in one direction only. I attach
to the door or turnstile at proper distances as many striking pieces as there are
openings in it, these striking pieces may be arranged either above or below the door
as most convenient or they may be attached to the body of door, I arrange them so
that as the door rotates each one strikes a lever which operates mechanism that
releases the locking apparatus when a suitable coin has been placed in a receptacle
provided to receive it.
The locking mechanism is fixed at a convenient height to the door post or its
equivalent fixed part and consists of a bracket to which the locking lever is pivoted,
in front of the locking lever a swing bolt or a sliding block is arranged so that in its
normal position it interveens to prevent more that a limited motion of the locking
lever, and consequently prevents the opening of the door or turnstile while the
before mentioned pawl and rack prevents it moving backwards.

page_text: To enable the door to be released I arrange a hopper carrier working on the
same centre as the locking lever, to this carrier a hopper with a projecting flap is
connected by a hinge, when a suitable coin is dropped into the hopper and the locking
lever is operated by the striking piece previously described an attachment to the hopper
carrier operates the swing bolt or the sliding block whichever may be used and moves
it so as to allow a free passage for the locking lever which carries forward the hopper
carrier till the hopper engages into a catch when the locking lever returns to its
normal position and the hopper being temporily held while the carrier is moved back
by the locking lever, a motion at the hinge opens the flap and releases the coin when
the hopper resumes its normal position and the carrier attachment being withdrawn
the swing bolt or the sliding block is free to move back and re-lock the door.
A portion of the flange of the hopper flat is cut away on one side so that if a
coin of less than the proper size is used it will drop straight through without being
available for moving the hopper carrier.

1 GEORGE WILLIAMSON formerly of 9 Nursery Mount Road Hunslet Leeds but
now of 14 Ward Street Hunslet Road Leeds in the County of York 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 providing new or improved means for enabling the
fastenings of turnstiles, doors, gates, barriers or platforms to be released and for
collecting the fee charged for passing through or using the same, this I effect by
arranging the fastenings of the turnstile or its equivalent so that when a proper coin
or token is placed in a receptacle provided for the purpose it will form a filling piece
or key and enable the user to undo the fastenings by the ordinary act of pushing
open the door or turnstile (or in the case of a platform by standing upon it) without
any other act being necessary.
I will describe my invention as applied to a turnstile or rotating door from which
its application to analagous uses will be understood.
When the invention is applied to a turnstile or rotating door I connect a pawl
arranged to engage with the teeth of a circular rack in the top or the bottom of frame
in the ordinary manner to ensure the motion being in one direction only. I attach to
the door or turnstile at proper distances as many striking pieces as there are openings
in it, these striking pieces may be arranged either above or below the door as most
convenient, or they may be attached to the body of the door. I arrange them so that
as the door rotates each one strikes a lever which operates mechanism that releases the
locking apparatus when a suitable coin has been placed in a receptacle provided to
receive it.
The locking mechanism is fixed at a convenient height to the door post or equivalent
fixed part and consist of a bracket to which the locking lever is pivoted. In front of
the locking lever a swing bolt or a sliding block is arranged so that in its normal
position it intervenes to prevent more than a limited motion of the locking lever and
consequently prevents the opening of the door or turnstile while the before mentioned
pawl & rack prevents it moving backwards.
To enable the door to be released I arrange a hopper carrier working on the same
centre as the locking lever, to this carrier a hopper with a projecting flap is connected
by a hinge. When a suitable coin is dropped into the hopper it falls between a pro-
jection on the locking lever and a part of the hopper carrier and the locking lever
being operated by the striking pieces previously described comes in contact with the
coin and carries forward the hopper carrier. An attachment to the hopper carrier
operates the swing bolt or the sliding block whichever may be used and moves it so as

page_text: to allow a free passage for the locking lever which carries forward the hopper carrier
till the hopper engages into a catch when the locking lever returns to its normal
position and the hopper being temporarily held while the carrier is moved back by the
locking lever a motion at the hinge opens the flap and releases the coin, when the
hopper resumes its normal position.
A portion of the flange of the hopper flap is cut away on one side so that if a coin
of less than the proper size is used it will drop straight through without being available
for moving the hopper carrier.
According to another method I employ a hopper carrier which has a hopper attached
to it, and I use a pusher for the purpose of liberating the coin when required, this
pusher consists of a piece of metal pivoted to the before mentioned bracket at a small
distance behind the pivot on which the hopper carrier works. On this locking lever
I form projections which engage with projections on the pusher so as to move it
forward at the same time that it is moving forward the hopper carrier, the radius of
the projections being so arranged that the pusher moves more rapidly than the carrier.
In consequence of this differential rate of motion the upper part of pusher comes in
contact with the upper part of the hopper and pushes it forward so as to take off the
nip" from the coin and leave it free to roll out, this is assisted by a projecting part
of pusher which is inserted at the back of coin and gives it a start.

In the accompanying drawings Fig. 1 is a front elevation, Fig. 2 an end elevation,
and Fig. 3 is a plan view of a turnstile fixed on the spindle A, near the foot of the
spindle is fixed a wheel B which carries a catch to engage in the ratchet-teeth in the
foundation and prevent the turnstile from being moved backwards. The wheel B has
on its perhiphery four striking pieces which as the turnstile is rotated come in contact
each in turn with one end of the lever D and move it sufficiently to allow them to pass.
The lever D is pivotted at E to the foundation and the other end of the lever engages
with the rocking lever F and causes it to lift the connecting rod G and locking lever E
each time that one of the striking pieces on the wheel B passes the end of the lever D);
when the striking piece has passed, the weight of the connecting rod G restores the
parts to their normal position.
The locking lever His pivotied to a bracket 1, which is fixed to the upright J,
which supports the turnstile; and when the swing bolt intervenes between the locking
lever H, and the bracket I, so as to prevent the movement of the lever H, the move-
ment of the lever D, and the wheel B, will also be stopped, and the turnstile will be
locked.
Figs. 4 and 5 show the wheel B, the catch C, the lever D, and the rocking lever F,
on a larger scale.
Fig. 6 is a side elevation of the unlocking mechanism, which is also partly shown in
Fig. 2. Fig. 8 is a plan view, and Fig. 9 an end elevation of same, and Fig. 7 is
partly an end elevation, and partly a section of the same, through the hopper
carrier K. The unlocking mechanism is carried by the bracket I, which is fixed to
the upright J, as previously stated. The locking lever H, is pivotted to the bracket I,
at L, and has a limited amount of movement when actuated by the connecting rod G,
and is prevented from making its full movement by the intervention of the swing
bolt M, which hangs across its path. Kis the hopper carrier which strides across the
bracket I, and the locking lever H, and is pivotted at L, the upper part of it terminates
in a hopper S, which has a slanting projection O attached to it. The hopper carrier
is held in position by the stop N. The projection O is arranged to overlap a corre-
sponding projection P on the swing bolt M. Q is a shoot, into which the coin is
inserted and R is a drop lever for holding the coin until it is required to be
released.
The hopper carrier consists of two plates or surfaces K, wide enough apart to allow
a coin to pass freely between them, and forming a narrow chamber in continuation of
the hopper S when the carrier is in its normal position this chamber or slit T, corre-
sponds with a notch U in the locking lever. The hopper carrier K is also cut away
at V, so as to allow the lever H to move when there is no coin in the slit T. If now
it is attempted to move the turnstile the rod G lifts the locking lover H a little, until

page_text: it is stopped by the swing bolt M, when no further movement can take place; and on
the pressure on turnstile being removed the parts return to their normal position. If
however a coin is inserted in the shoot it drops into the hopper S, and thence into
the slit T, where it intervenes between one of the sides of the slit or chamber T in
hopper carrier, and one side of the notch U in locking lever, so that the lever cannot
be moved without also moving the carrier K; the coin is prevented from falling out
of the slit T by the drop lever R, but the position of the drop lever is so arranged that
it will allow a coin of less than the predetermined size to fall through without affecting
the mechanism. When a proper coin has been inserted as described, and the turnstile
is pushed, the rod G lifts the locking lever H as before, but in doing so the hopper
carrier K is moved with it by the intervention of the coin, and the projection O pushes
to one side the swing bolt M, so as to allow the locking lever its full movement ;
is, the movement necessary for the striking piece on the wheel B at foot of
turnstile, to pass the end of the lever I), when the parts return by gravity to their
normal position.
that
X is a pusher pivotted to the bracket I at the back of the hopper carrier, but some
distance clear of it. When the lever H is moved, a pin or projection on it Y, carries
forward the pusher at a quicker rate than the carrier K is being moved, so that after
the hopper carrier has been moved enough to prevent its being intercepted by the
swing bolt, it is overtaken by the pusher X, which pushes it away from the coin, or
"takes off the nip"; at the same time the drop lever R is lifted by the pusher acting
on it at Z, and a projection A¹ on the pusher, is inserted at the back of coin to give it
a start, so that it will roll out during the forward movement of the carrier, into a
receptacle provided to receive it. B is a pin or projection on the locking lever,
arranged so as to strike the hopper carrier when the lever is falling back, and to restore
it to its normal position.
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 arrangement of apparatus above described, for effecting the unlocking of
gates, doors, turnstiles, or the like, in which, on a coin of certain size being inserted,
it forms a connecting piece, or filling piece, between a locking lever and a hopper
carrier, and enables the latter to move out of way a'swing bolt, when actuated by the
movement of the door or turnstile.
"
2. The arrangement of apparatus above described, for effecting the release of
the coin, by means of a pusher acting at the back of hopper carrier, while
the later is being pushed forward by the movement of the door or turnstile.
3. The combination of the arrangements of apparatus named in Claims 1 & 2.
