Complete Specification Left, 27th Feb., 1893-Accepted, 1st Apr., 1893
PROVISIONAL SPECIFICATION.
Improvements in Self Registering Turnstiles.
I, HARRY DORNING BAILEY, of the firm of W. H. Bailey and Company Limited,.
of Albion Works, Salford, in the County of Lancaster, Hydraulic Engineers and
Brassfounders, do hereby declare the nature of this invention to be as follows:-
My invention relates to turnstiles employed to automatically register the number
of people passing through them, and the object of my invention is to adapt the
turnstile to allow people to pass out or back without affecting the registering or
indicating apparatus.
In fitting up a registering turnstile according to my invention instead of fixing
the arms directly to the spindle of the turnstile I connect them to the spindle by a
ratchet wheel and pawl, or equivalent means, so that when a person enters through
the stile and turns its arms part of a revolution the registering apparatus is actuated
in the ordinary manner; but when a person passes through the turnstile in the
reverse direction the arms turn freely over the ratchet or equivalent gearing without
actuating the registering apparatus.
By this construction the turnstile can be moved freely in either direction but the
registering apparatus will act only when the arms turn in one direction.
Dated this 24th day of May 1892.

COMPLETE SPECIFICATION.
Improvements in Self Registering Turnstiles.
I, HARRY DORNING BAILEY, of the firm of W. H. Bailey and Company
Limited,
of Albion Works, Salford, in the County of Lancaster, Hydraulic Engineers and
Brassfounders, 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 turnstiles employed to automatically register the number
of people passing through them, and the object of my invention is to adapt the
turnstile to allow people to pass out or back without affecting the registering or
indicating apparatus.
In fitting up a registering turnstile according to my invention instead of fixing
the arms directly to the spindle of the turnstile I connect them to the spindle by a
ratchet wheel and pawl, or equivalent means, so that when a person enters through
the stile and turns its arms part of a revolution the registering apparatus is
actuated in the ordinary manner; but when a person passes through the turnstile
in the reverse direction the arms turn freely over the ratchet or equivalent gearing
without actuating the registering apparatus.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying four sheets of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a plan and Fig. 2 is an elevation partly in section of a turnstile to
which my invention is applied.
Fig. 3 is an elevation of part of the turnstile partly in section.
Fig. 4 is a section on the line A B, Fig. 3.
Fig. 5 is a plan and Fig. 6 a sectional elevation of mechanism for bringing the
arms of the turnstile into their proper position after anyone has passed out.
a a are the arms of the turnstile fixed in the boss 6 loose on the spindle c, d is the

page_text: ratchet wheel fixed on the spindle c operated when anyone enters through the turn-
stile by the pawl e carried by the boss ; f is a ratchet wheel mounted at the upper
part of the spindle c against which is pressed the retaining catch f₁ by the spring f
to prevent the spindle c turning back when anyone is passing out through the turn-
stile, the pawl e then moving freely over the teeth of the ratchet d.
Fixed on the sleeve b' of the boss b, see Figs. 5 and 6, is a star wheel g on which
are mounted four antifriction rollers ; i is a block fixed on the sliding spindle j on
which is a collar and the spring which presses against the collar forces the
block against a roller or rollers to bring and hold the arms of the turnstile in
their correct position after anyone has passed out through the turnstile. The
spindle c of the turnstile actuates the indicator contained in the box through its
extension e' when anyone enters through the turnstile, in the ordinary or in any
other convenient manner.
By this construction the turnstile can be moved freely in either direction but the
registering apparatus will act only when the arms turn in one direction.
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. A turnstile movable in either direction provided with a ratchet and pawl or
equivalent mechanism so connected to the turnstile that it will actuate the
indicator when turned in one direction and not when turned in the opposite
direction.
2. The use of a loose boss carrying the arms of the turnstile and a pawl in
combination with a ratchet wheel and spindle substantially as and for the purposes
herein set forth. •
3. The combination with the ratchet and pawl or their equivalents for allowing
persons to pass out through a turnstile, of the mechanism described for bringing
the arms of the turnstile into their proper position after anyone has passed out.
