Improvements in Coin-operated Turn-stiles.
I, HENRY CASPAR, residing at the corner of Dryads and Thalia Streets, in the
City of New Orleans, State of Louisiana, United States of America, Gentleman,
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 relates to improvements in coin operated turn-stiles.
In the accompanying drawings:
Fig. is a perspective view of a turn-stile, having my improvements applied
thereto.
Fig. 2 is a partial horizontal sectional view on the line - of Fig. 1, showing
the ratchet and stay-bolt.
Fig. 3 is a central vertical sectional view.
Fig. 4 is a central vertical sectional view taken at right angles to that shown in
Fig. 3.
Fig. 5 is a detail view partly in section showing the interior of the lock, the
periphery of the cylinder and the position of the floors relatively thereto.
Fig. 6 is a detail sectional view showing the position of the shaft and rotating
arms to which the doors are attached when in place.
Fig. 7 is an enlarged side view of the lock with the side removed showing the
coin before operation.
Fig. 8 is a top sectional view of the same.
Fig. 9 is a view similar to Fig. 7 after operation showing the coin in dotted lines
as it passes down out of the lock into the money-box, and
Fig. 10 is a view similar to Fig. 8 showing the parts after the coin has
operated.
Referring more particularly to the drawings, A, indicates the posts; B, the
bottom, and C, the top, of a frame within which my improved stile is located.
Secured at its ends to the top and bottom of the frame is a post E, around which
the wings or doors D are arranged to swing or rotate. Arms 9, are secured to the
ring or sleeve 11, and secure the doors in position. Balls 10, may be placed
between the ring 11 and a base-piece K at the bottom of the post E to prevent
undue friction in swinging the doors around the post.
Instead of making the post out of a single piece having a shell or cylinder G,
formed at the central portion, it can be made of two parts Faving the adjacent ends
secured to or connected with the casing in any suitable manner.
A rim F is placed in the inner edge of each of the wings so that they will pass
The rims are
freely around the cylinder without coming in contact with it.
secured at their ends to rings around the shaft similar to the ring 11, and the upper
ends of the doors may be secured to a ring by means of arms 9 in the same manner
as the lower ends.
Located within the cylinder G, is the lock 3, which fits within an opening in the
cylinder at one end and is secured to the opposite side of the cylinder by means of
the arms 1, and 2, and the screws O which pass through the cylinder into the ends
of the arms.
The bolts T and Q extend entirely through the frame or shell of the lock and
project therefrom at each end. The rear portion of each bolt is reduced or turned
down and upon the reduced portions are spiral springs P.
The rear ends of these springs have a bearing against the rear inner wall of the
lock casing and the forward end of the spring on the bolt Q bears against a stud
on the stem of the bolt, as hetter shown in Figs. 9 and 10 of the drawing while the
forward end of the spring on the bolt T¹ has its bearing against the lateral arm W

page_text: of the said bolt so that both bolts are normally held with their outer ends advanced.
The forward or outward movements of these bolts T¹ and Q are limited by means
of pins p
One of the bolts T' has a laterally projecting arm W through which the other
bolt passes. A latch V is pivoted at the rear end of the lock and has its free end
provided with a shoulder, which falls behind the arm W and prevents the
rearward movement of the bolt T. The outer end of the bolt Q is beveled or
inclined so that when the wings D are rotated around the post E, the rim F will
engage with the beveled portion of the bolt and push it back through the lock
until it will permit the rim and door to go past it. The outer end of the other
bolt T also projects out into the path of the rim F, but as it is not beveled or
inclined, the rim strikes squarely against its side and prevents the door from
rotating farther. In this manner the stile is locked and will not let any person past.
it until the square ended bolt T¹ has been withdrawn into the casing.
In order to unlock the bolt T¹ or release it so that it can be withdrawn into the
lock, a piece of money Z of the denomination required as the price of admission,
must be dropped into the slot S, in the top of the cylinder G. The coin passes
down through the chute R into the lock 3, through a slot, in its top and falls
upon a plate or latch T which is pivotally secured at one end and covers the exit 5
at the bottom of the frame.
The bolt has one of its sides cut away directly under the sloty, forming a
shoulder ½ which will bear against the edge of the coin and carry it back against
the end of the latch V, when the bolt is forced in by the pressure of the rim F,
against its outer or beveled end. As the end of the latch is above the centre of
the coin, the rearward movement of the coin will cause it to pass in under the end
of the latch and raise the shoulder out of engagement with the arm W and thus
release the bolt T. By this time the edge of the coin below the latch has been
forced against the arm W and pushes it back, and with it the bolt T. Thus by
the time the door D has passed around the cylinder far enough to push the bolt Q
entirely in out of the way, the bolt T has also been carried in out of the way and
the door can be swung on around and permit the passage of the person behind it.
To prevent the stile from being continuously rotated with the payment of only a
single admission fee, the end of the plate T is extended so as to project beyond the
casing G below the bolts Q and T¹ into the path of the wings D and thus be carried
around with the wings. This swinging of the plate draws it from under the coin
and lets it fall through the opening 5 in the bottom of the lock into the money-box 4
below. But as this does not happen until after the rim F has passed over the end
of bolt T the further rotation of that door is not interfered with but as soon as the
rim has cleared the end of bolt. T¹ the springs P force both bolts back into their
original position, which will prevent the passage of another door until another fare
has been deposited in the slot as above described.
To prevent the admission of a second fare into the lock before the parts have
returned to their normal position, the end of a hook-shaped arm X is swung in under
the slot and obstructs the passage so that another coin cannot pass through until
the arm has been withdrawn.
ولا
The arm X is secured to a spring actuated post X and is operated by means of
the plate T which presses against a pin t, that projects from the post X. The
rear edge of the plate T strikes against the pin t, and swings the arm X.
The plate T is preferably provided with a recess in its rear edge.which will
permit of the plate being carried back its required distance without coming in
contact with the post XI. A coiled spring U engages with the plate near its
pivotal end and returns it to its normal position as soon as its free end is released by.
the passage of the door D.
Whenever it is desirable to empty the money-box it is readily done by unlocking
the door 7 in the side of the cylinder G by the key 6 and swinging it back on its
hinges S. The contents of the box can then be removed, after which the door is
closed and locked and the device is again ready for aneration

page_text: To prevent the rotation or attempted rotation of the wings or doors backward or
in the wrong direction, a ratchet H is secured at the top of the doors, and a spring-
actuated pawl is caused to engage with the teeth of the ratchet when the doors
are moved backward, but which will slide over the teeth when they are rotated in
the right direction. A stay-spring L is secured to one side of the frame and kept
in the path of the doors by the spring N which will assist in preventing the back-
ward movement of the doors if the ratchet should become inoperative or before the
end of the pawl drops behind a tooth after the door had passed the lock and the
bolts had resumed their former position. By the use of my turn-stile, the attendance
of a gatekeeper is rendered unnecessary as the device will operate automatically
when the proper fare has been deposited and the door pushed away from the person
entering and it will only admit of the passage of one person at a time for a single
admission fee.
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. In a coin-operated stile, the combination with a post, of a lock secured thereto,
a series of wings or doors rotatable around the post and lock, two bolts within the
lock, one end of each of which projects out into the path of the wings and a latch
for locking one of the bolts, said latch being adapted to be released from the bolt
by a piece of money introduced into the lock, substantially as specified.
2. In a coin-operated stile, the combination with a post, of a lock secured thereto,
a series of wings or doors secured to rings around the post by means of arms, a rim
in the inner edge of each door at the lock, two bolts in the lock, one end of each of
which projects out into the path of the rims and one bolt having its end beveled or
inclined and having its side within the lock provided with a shoulder, a latch for
locking the other bolt and adapted to be released from the bolt by a coin forced
against it by the shoulder on the first mentioned bolt, substantially as described.
3. In a coin-operated turn-stile, the combination with a series of doors movable
around a common centre, of a lock having bolts projecting into the path of the
doors, a latch for locking one of the bolts and adapted to be operated by a coin, a
plate below the coin the free end of which projects into the path of the doors and
is operated thereby to release the coin, substantially as described.
4. In a coin-operated turn-stile, the combination with a series of doors movable
around a common centre, of a lock having a slot in its top, bolts projecting out into
the path of the doors, a post having an arin for obstructing the slot and a laterally
projecting pin, and a plate pivotally secured within the lock for engaging with the
pin and having its free end projecting out into the path of the doors, substantially
as specified.
