PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Indicating the Number of Passengers
Passing Through a Turnstile, Applicable for Indicating the
Number of Passengers Carried in a Tram-car or for any
Analogous Purpose.
We WILLIAM KIMPSTON of 131 Varley Street, Oldham Road, Manchester and
GEORGE FERRINGTON of 20 Rylett Street, Lower Broughton, Manchester, Machinists
do hereby declare the nature of our said invention to be as follows:-
This invention consists of a compact turnstile occupying little room and which is
designed for revolving a set of counters, one set for indicating the number of
passengers corresponding to the section or division of a tram journey and the other
set to indicate the number of passengers passing out during each stage of the journey.
In performing our invention we construct our improved turnstile with a hollow
standard or pillar supporting on its upper extremity a fixed cam or bracket. Inside
or above this standard is mounted a central shaft which on a level with the cam herein-
before mentioned carries a collar provided with a series of hinge joints in which
are suspended a corresponding number of falling arms-each of which is brought
to the horizontal position as it passes over the cam and having passed it immediately
falls to the vertical position again. In this manner we construct a turnstile-of
only half the usual width a consideration of some importance where space is so
limited as on the platform of a public conveyance.
By now having the central rod provided with a notched wheel for operating each
counter we are enabled to obtain an indication of the number of passengers passing
through the turnstile during each section of a journey.
The connection between the notch wheel and the counter consists of a hinged lever
having an arm jointed vertically at one extremity and which is designed to oporate
the lever as the notch wheel turns in one direction but to remain stationary if it
turns in the other direction. This lever carries at its other extremity a pawl taking
into the ratchet teeth of the units wheel or spindle of the counting mechanism-a
long spiral spring is applied to the arm to give it a constant tendency to lie against
the teeth of the notch wheel.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Indicating the Number of Passengers
Passing through a Turnstile, Applicable for Indicating the
Tram-car or for any
Number of Passengers Carried in a
Analogous Purpose.
We WILLIAM KIMPSTON of 131 Varley Street, Oldham Road, Manchester and
GEORGE FERRINGTON of 20 Rylett Street Lower Broughton, Manchester, Machinists
do hereby the nature of our said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following state-
ment :-
This invention consists of a compact turnstile occupying little room and which is
designed for revolving a set of counters one set for indicating the number of
passengers corresponding to the section or division of a tram journey and the

page_text: other set or sets to indicate the number of passengers carried during each further
stage of the journey.
On the accompanying drawing we illustrate in Fig. 1. a side view of the entire
apparatus arranged in a doorway Fig. 2 is a sectional plan (on an enlarged scale)
of Fig. 1. taken on the line a-b Figs. 3 and 4 are front and plan views respectively
of the indicating mechanism also on an enlarged scale.
In performing our invention we construct our improved turnstile with a hollow
standard or pillar a supporting on its upper extremity a fixed cam or bracket b.
Inside or above this standard is mounted a central shaft c which on a level with
the cam or bracket 6 carries a collar d provided with a series of hinge sockets e in
which are suspended a corresponding number of falling arms each of which is
brought to the horizontal position as in revolving with the shaft it passes over the
cam b and then having passed it immediately falls to the vertical position again. In
this manner we construct a turnstile of only half the usual width a consideration
of some moment where the space is so limited as on the platform of a public
conveyance or in a door way.
By now having the central shaft c provided with a similar notched wheel g for
operating each counter (and which may be arranged one above another) we are
enabled to obtain an indication of the number of passengers passing through the
turnstile during each section of the journey. The operating connection between the
notch wheel g and the counter contained within the casing k consists of a pawl
lever mounted upon a horizontal stud i.
This pawl lever carries at its rear extremity'a weighted pawl 7 taking into the teeth
of the ratchet wheel in upon the units wheel or spindle m¹ of the counting mechanism
whilst the front extremity ; of this same lever is hinged vertically and is kept
distended by a long spiral spring k so as to be caught between the notches of the
notched wheel g as it turns in one direction but to remain stationary by reason of the
part turning upon its hinge if the notch wheel turns in the other direction.
In this manner and by so oscillating the lever h upon its stud once for every
time an arm f passes over the cam the units wheel is revolved and so an
indication is obtained in the counter of the number of persons passing through the
turn-stile.
To prevent the central shaft or turnstile being tampered with or turning accidently
we sometimes affix thereupon an additional slotted collar and employ a lever
handle y under the control of the official in charge to lock into one of a series of say
four slots formed in the edge of the said collar or we lock the mechanism in any
other equivalent manner.
In Figs. 5 and we illustrate a front view and plan view respectively of an
alternative arrangement of the pawl and ratchet mechanism for conveying the
motion of the turnstile to the counters. It consists of a cranked lever o mounted
upon the horizontal stud p. This lever has a pawl q at one extremity taking into the
ratchet wheel r of the counters and a hinged fingers at the other end.
This lever o is operated by each of the projecting arms (branching from the
central shaft u) coming in contact with it in turning in the direction of the arrows
but remains stationary as herein before described when the turn-stile shaft u is revolved
by the turnstile in the opposite direction.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we claim
is:
==
1st. The improved combination and arrangement of turn-stile substantially as herein-
before described and illustrated on the accompanying drawing.
2nd. In a turn-stile the employment of a central shaft carrying hinged arms in
combination with a fixed cam mounted and operating substantially as and for the
purpose hereinbefore described and illustrated on the accompanying drawing.

page_text: 3rd. In a turn-stile the employment of a notched wheel and hinged pawl lever for
operating the counters in one direction and for escaping the same in the other
substantially as hereinbefore described and illustrated on the accompanying drawing.
