Improvements in Registering Turn-stiles.
1, ALFRED WILLIAM MONEY, of 24, Ravenscourt Gardens, Hammersmith, in
the County of London, Electrical Engineer, do hereby declare the nature of
this invention to be as follows:-
-
This invention has reference to turnstiles of the kind that are employed at
the entrances to exhibitions and other places where the number of persons enter-
ing is to be registered. As is well known these turnstiles usually consist of
rotative shafts having a number of radial arms or members which are so disposed
relatively to the passage through which the persons pass to enter the exhibition
that when said arms are approximately at right angles to the passage the turn-
stile remains locked until released by the attendant. When so released they are
free to be turned (by the person entering) a distance of one step, the next radial
arm being at the same time brought into position for stopping the passage until
the turnstile is again released. If however the attendant be dishonest he can
stop the turnstile in a position about half way between its step, in which position
a space will be left between the outer extremity of the radial arms and the
wall or rail forming the side of the passage controlled by the turnstile, such space
being sufficient to enable subsequent persons to squeeze through without causing
the turnstile to register their entrance.
Now the object of my invention is to so construct these turnstiles that even
if they be set into the aforesaid half-way position it will not be possible for a
person to pass them.
For this purpose I provide a device which may be in the form of a hinged
shutter which is so connected with suitable mechanism operated by the rotary
movement of the turnstile, that as the latter performs its step by step rotary move-
ment, the said hinged shutter will be oscillated and at each step of the turnstile
will be caused to come into a position to fill up the gap that would otherwise
exist, (when the turnstile is in its half-way position), between the outer ex-
tremities of the radial arms and the opposite wall or rail.
The mechanism by which this movement of the hinged shutter is effected may
consist of a crank on the axle of the hinged shutter, connected by a rod or link
to another crank forming part of a pinion situated adjacent to the axle of the
turnstile. This pinion may be geared with a toothed wheel which is revolved.
directly or indirectly by the turnstile, the gearing being such that an oscillatory
movement will be imparted to the hinged shutter at each step in the rotary
movement of the turnstile. That is to say, when one of the arms of the turnstile
is at right angles to the passage through which persons pass from one side of
the turnstile to the other, the said hinged shutter will lie out of the way, but as
the person, in passing through the passage, causes the said radial arm of the
turnstile to shift forwardly, the said hinged shutter will advance behind the
person and lie contiguous to the outer end of the succeeding radial arm of the
turnstile, thus effectually blocking the passage and avoiding any chance of a

page_text: second person being able to squeeze through the space existing between the
extremities of the radial arms and the side wall.
I do not wish to confine myself to the specific means above stated for causing
the hinged shutter to perform its oscillations as it will be obvious that other
means may be employed for the purpose.

"Improvements in Registering Turn-stiles.
I, ALFRED WILLIAM MONEY, of 24, Ravenscourt Gardens, Hammersmith, in
the County of London, Electrical 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 has reference to turnstiles of the kind that are employed at
the entrances to exhibitions and other places where the number of persons enter-
ing is to be registered. As is well known these turnstiles usually consists of
rotative shafts having a number of radial arms or members which are so disposed
relatively to the passage through which the persons pass to enter the exhibition
that when said arms are approximately at right angles to the passage, such
passage is stopped or barred, and the turnstile remains locked until released by
the attendant. When so released it is free to be turned (by the person entering)
a distance of one step, whereby the next radial arm will be brought into position
for stopping the passage and will be held in such position until the turnstile is
again released. If however the attendant be dishonest he can stop the turnstile
in a position about half way between the step, in which position a space will
be left between the outer extremity of the radial arms and the wall or "rail
forming the side of the passage controlled by the turnstile, such space being
sufficient to enable subsequent persons to squeeze through without causing the
turnstile to register their entrance.
Now the object of my invention is to so construct these turnstiles that even
if they be set into the aforesaid half-way position it will not be possible for a
person to pass them.
For this purpose I provide a device which may be in the form of a hinged
frame or shutter, so connected with suitable mechanism operated by the rotary
movement of the turnstile, that as the latter performis its step by step rotary
movement, the said hinged frame or shutter will be oscillated and at each step
in the movement of the turnstile, will be caused to come into a position to fill
up the gap that would otherwise exist between the outer extremities of the
radial arms and the opposite wall or rail, when the turnstile is in its half-way
position.
In order that my invention may be clearly understood and readily carried
into effect I will proceed to describe the same more fully with reference to the
accompanying drawings, in which:
Figure 1 is an elevation, partly in section, of a turnstile having my improve-
ments applied thereto;
Figures 2 and 3 are plans of Figure 1 showing the parts in different positions ;
and
Figure 4 is a view similar to Figure 1 showing a slightly modified construction.

page_text: In these drawings the detent and registering mechanism is omitted, for sake
of clearness. Such mechanism may be of any desired and well known con-
struction.
a is the aforesaid rotative shaft of the turnstile, and b, b are the radial arms or
members secured to said shaft. c, c² are the two parts of the railing or frame
of the turnstile, between which parts is a passage through which persons enter-
ing the exhibition or other enclosure, pass as above mentioned. d is the afore-
said frame or shutter which is secured to a shaft e carried in bearings f, f
mounted upon the part c¹ of the frame, or formed in the base plate thereof.
Referring now particularly to Figures 1 to 3, g is a toothed wheel secured to
the shaft a below the base plate of the framing c. h is a pinion gearing with
the wheel g and mounted upon a stud secured in such base plate. Rigidly con-
nected to this pinion is a crank i to which is pivoted one end of a connecting
rod . The other end of this rod k is pivotally connected to a crank / secured
to the shaft e. The relation of the number of teeth upon the pinion to that
of the teeth upon the wheel g is such that the pinion makes one revolution for
each step in the rotary movement of the shaft a. The arrangement is such
that, while the shaft a is moving through the requisite angle to withdraw one
arm b from the stopping position and to bring the next arm into such position,
the frame or shutter d will be oscillated or moved forwardly from its inoperative
position (shown in Figure 2) to a position contiguous to the outer end of the
arm that is approaching the stopping position, and so close up the gap that
would otherwise be formed between such arm and the frame c¹ (see Figure 3).
The passage is thus effectually barred and any chance of a person being able to
squeeze through the space existing between the extremities of the radial arms
and the side wall is avoided. As the succeeding arm reaches the stopping
position the frame or shutter will be moved back again into its inoperative
position. The turnstile illustrated has four arms, and consequently in this
case the ratio of the number of teeth upon the pinion to the number of teeth
upon the wheel is 1 to 4.
The gearing is preferably enclosed in a casing m secured to or forming
part of the base plate or plates of the turnstile.
When it is desired to apply my invention to existing turnstiles it may be
necessary to place part or even the whole of the gear above the base plate or
plates of the turnstile. The connecting rod, which occupies very little space
as regards depth, can generally be arranged in a shallow recess in the floor or
ground below the base plates; but should it be necessary to have this rod above
the floor then a slight double incline may be arranged to form a bridge over the
rod in the passage through which persons pass the turnstile.
Figure 4 shows one form of my invention applied to an existing turnstile.
It will be seen that there are two sets of toothed wheels and pinions g, h, and
g', h¹, for effecting the increase in the angular movement of the crank i
relatively to that of the shaft a. The purpose of this arrangement is to avoid the
use of the comparatively large gear wheel that is required when only one wheel
and pinion are employed, which large gear wheel would, being above the floor
project into the path of persons passing the turnstile. In the example shown
in Figure 4 the cranks i and I and the connecting rod k are arranged below the
floor in a separate casing m¹.
Although I have shown arrangements wherein the connecting rod has an
angular as well as a reciprocating movement, it will be readily understood that
I can so construct the operating parts as to cause the reciprocation of the said
rod to be entirely rectilinear, slots being formed in the rod transversely in which
slots the crank pins work. When using such an arrangement, that portion of
the rod crossing the passage between the two parts of the turnstile may consist
of a bar adapted to lie in a narrow groove in the floor, its upper surface being
flush with the top of said groove. I thus avoid the necessity for a casing
arranged under the floor or for an incline or bridge over the connecting rod.

page_text: I also wish it to be understood that I do not confine myself to the specific
means herein described for causing the hinged frame or shutter to oscillate, as
it is obvious that other means may be employed for the purpose.
For example, a suitable cam may be secured to the shaft a the said cam being
adapted to operate the crank directly or indirectly.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A turnstile provided with a hinged frame or shutter or similar device
adapted to oscillate at each step in the movement of the turnstile for the purpose
specified.
2. A turnstile having a hinged shutter adapted to be oscillated by means sub-
stantially as described with reference to the accompanying drawings for the
purpose specified.
