PROVISIONAL SPECIFICATION.
Improvements in Turnstiles.
We, WILLIAM OKEY SNYDER of 28 Warwick Road, Gentleman, and WILLIAM
SWEENEY of 7 Kempsford Gardens, Musician, both of Earl's Court, in the County
of Middlesex, do hereby declare the nature of our invention to be as follows:-
The improvements have for their object to save space and expense by con-
structing turnstiles of or with one stile or gateway which may serve both for
entrance and exit, for the former in conjunction with and causing record on the
present or other tell-tale, but for the latter free of and without record on said
tell-tale. The improvements consist in making the spindle which carries the arms
or gate of the tell-tale of or in two parts an upper without arms, and a lower
carrying the arms or gate the upper made to work in or on or over the other;
the upper spindle carrying an upper sliding clutch which is made to slide on the
upper spindle and is capable of being brought into or out of gear with a lower
clutch which is fixed on or to the lower spindle. The lower spindle carries also at
or near its base an upper clutch gear which is made capable of sliding on said
spindle and of being brought into gear with a lower clutch which is made a fixture
on or in the platform or floor on or in which the lower spindle turns. The upper
clutch worked on the upper spindle is fitted with a collar and depending sleeve
which covers over both clutches, so that they cannot be got at by hand. The
sliding clutch on the lower spindle is lifted in and out of gear by a forked or other
lever operated by the foot. The usual or other recording or tell-tale device is
conveniently operated from and by the upper spindle.

COMPLETE SPECIFICATION..
Improvements in Turnstiles.
We WILLIAM OKEY SNYDER, Gentleman of 28 Warwick Road and WILLIAM
SWEENEY, Musician, of 7 Kempsford Gardens, both in Earls Court in the County
of Middlesex 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 :-
The improvements have for their object to save space and expense by con-
structing turnstiles of or with one stile or gateway which may serve both for
entrance and exit, for the former in conjunction with and causing record on the
present or other tell tale but for the latter free of and without record on said
tell tale.
The improvements consist is making the spindle which carries the arms or gate
of the telltale of or in two parts, an upper without arms, and a lower carrying the
arms or gate the upper made to work in, on or over the other. The upper spindle
carries the upper member of a clutch which is made to slide on the upper spindle
and is capable of being brought into or out of gear with the lower member of the
clutch which is fixed on or to the lower spindle. The lower spindle carries also at
or near its base, the upper member of a clutch gear which is made capable of
sliding on said spindle but without revolving thereon and of being brought into
gear with the lower member of this clutch which is made a fixture on or in the
platform or floor on or in which the lower spindle turns.

page_text: Over the upper clutch is fitted a sleeve which covers over the clutch so that it
cannot be got at by hand. The sliding member of the clutch on the lower spindle
is lifted in and out of gear by a forked or other lever operated by the foot of the
attendant. The usual or other recording or tell tale device is conveniently operated
from and by the upper spindle.
The direction of the slope of the teeth of the lower pair of clutches is opposite
to that of the teeth of the upper pair of clutches. The lower pair of clutches is of
the usual kind to prevent the turnstile from turning to admit persons unless the
clutch is lifted out of locking action by the pedal lever operated by the attendant,
it does not however interfere with or prevent use of the turnstile as an exit. The
upper pair of clutches is also intended to separate automatically when the turnstile
is used as an outlet so that the turning of the stile may be without action on the
recording telltale. If a pin or ball be inserted so as to prevent the upper pair of
clutches from separating; then the stile cannot be used as an exit, because while
unable to lift the upper clutch, the latter being prevented at all times from
revolving backwards by a ratchet and ratchet wheel, acts therefore as a lock
against backward movement of the turnstile.
This construction is shown in the annexed drawing in which
Fig. 1 is a side elevation of the turnstile and frame.
Fig. 2 is a plan view of the base thereof.
Fig. 3 is a perspective view of the central arbor of the stile.
Fig. 4 is a view of the upper arbor which carries the tell tale actuating clutch.
Fig. 5 is the said clutch in plan view.
Fig. 6 are the toothed wheel and ratchet which prevent the arbor (Fig. 4) from
revolving in the reverse direction.
A is a suitable frame. B is the arbor of the turnstile. E' E' the arms thereof
fixed in any suitable way to the bosses D D'. The lower end of the arbor revolves
in a step bearing at band just above this bearing is squared at U for the upper
member C of the lower pair of clutches C C the lower member of which is fixed
to or made part of the frame A. C' is the foot lever by which the attendant lifts
the clutch C to admit persons. The inclined teeth of the clutch enable the upper
member to rise automatically to allow persons to pass out.
The lower member E2 of the upper clutch E is made part of the arbor B at its
upper end, and centrally within this end of the arbor B is a pit or cavity g' serving
as a step bearing for the upper arbor B¹, the upper bearing of which is in the
frame, and it is suitably connected at its upper end with the mechanism of the
tell tale. The upper member E of the upper clutch slides on the squared part F
of the arbor B', and the teeth of this clutch are so inclined that when used as an
inlet, the turnstile carries with it the arbor B' on its rotary movement, and when
used in the contrary direction as an exit, the upper member of the clutch E rises
automatically since the pawl H¹ acting on the ratchet wheel H on the arbor B¹
prevents the latter from turning in this direction. To give a secure bearing to the
turnstile, the upper end of the arbor B is carried in a collar bearing R on a
bracket L or equivalent part of the framework.
It is preferable to surround the clutch E and arbor B' with a cylindrical cover S
to prevent unauthorized access to the mechanism.
If a pin or bolt is inserted in such a way above the clutch E that the two
members of this clutch are held in engagement with each other then the turnstile
is locked as an exit since the upper member of the clutch E cannot revolve in a
reversed direction and will not suffer the turnstile to do so unless it can rise to
allow the teeth of the lower member to pass.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is.
1. A turnstile adapted to revolve in either direction in combination with a clutch
adapted to connect the stile with the arbor of a tell tale or counter whereby the

page_text: revolutions of the stile in one direction are registered by the telltale and in the other
direction are without action thereon.
2. A turnstile having a clutch suffering movement in one direction but locking
the stile against movement in the other direction, a lever for unlocking this clutch
for use of the stile as an inlet, a second clutch automatically transferring the
revolutions of the stile in one direction to a tell tale and rising automatically to
suffer revolution of the stile in the opposite direction substantially as set forth and
with or without means for locking the last mentioned clutch for the purpose set
forth.
