I WILLIAM HENRY DOUGHERTY of 248 Chapel Street Bedford Leigh in the
County of Lancaster Pattern Maker do hereby declare the nature of my invention
for "IMPROVEMENTS IN TURNSTILES FOR INDICATING THE NUMBER OF PERSONS
PASSING INTO A THEATRE OR OTHER PLACE to be as follows:-
"
The object of my invention is to enable the same turnstile to serve both for
ingress and egress and at the same time to prevent the setting backwards of the
indicating apparatus by moving the turnstile round in the reverse direction.
The wings or gates of the turnstile arc attached to a central boss which is
mounted so as to turn loosely upon a vertical shaft or axis which latter is supported
in suitable bearings at top and bottom and is also capable of revolving under
conditions hereinafter explained.
Inside the loose boss I key or otherwise fix onto the vertical shaft a ratchet
wheel, into which works a dog carried by a boss, the teeth of the wheel being so
arranged that the turning of the stile in the direction of ingress will turn the
vertical shaft also, but the turning of the stile in the direction of egress will not
turn the said shaft as the dog over runs the teeth of the ratchet.
Instead of fixing the ratchet wheel on the vertical shaft the ratchet teeth may be
formed inside the boss and the dog carried by a plate or arm keyed or fixed on the
shaft.
The upper end of the vertical shaft actuates the indicating apparatus in the
usual manner.
At or near the foot of the vertical shaft is fixed a disc provided with four holes
corresponding with the four wings or gates of the stile, and a treadle is provided
having a stud taking into these holes to prevent the stile from being turned
without the attendant presses his foot upon the treadle, and to prevent the spindle
from being turned round in the reverse direction by means of the stile there is a
spring bolt beneath the disc which also takes into these holes; one side of the
holes and one side of the bolt being bevilled to allow the spindle moving round in
the direction of ingress only.

I WILLIAM HENRY DOUGHERTY of 248 Chapel Street Bedford Leigh in the
County of Lancaster Pattern Maker do hereby declare the nature of my invention
for IMPROVEMENTS IN TURNSTILES FOR INDICATING THE NUMBER OF PERSONS
PASSING INTO A THEATRE OR OTHER PLACE and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to enable the same turnstile to serve both for
ingress and egress and at the same time to prevent the setting backwards of the
indicating apparatus by moving the turnstile round in the reverse direction.
In order that my invention may be clearly understood I have annexed bereunto
a sheet of drawings illustrative thereof in which Fig. 1. is an elevation and Fig. 2.
a plan of my improved turnstile. Fig. 3 is a sectional elevation (taken through
the line A. B. Fig. 2).
Fig. 4. is a sectional plan (taken through the line C, D Fig. 1.) Fig. 5 is a
detached view of a modification hereafter referred to.
The wings or gates a, a of the turnstile are attached to a central boss b, b which
is mounted so as to turn loosely upon a vertical shaft or axis c, c which latter is
supported in suitable bearings at top and bottom and is also capable of revolving
under conditions hereinafter explained.
Inside the loose boss b, b I key or otherwise fix onto the vertical shaft c, c a
ratchet wheel d, d, into which works a dog or catch e, e carried by the boss b, b, the
teeth of the wheel d, d being so arranged that the turning of the stile in the
direction of ingress will turn the vertical shaft c, c also, but the turning of the stile
in the direction of egress will not turn the said shaft as the dog or catch e, e over-
runs the teeth of the ratchet wheel d, d.
Or, instead of fixing the ratchet wheel on the vertical shaft c, c the ratchet teeth
may be formed inside the boss b, b and the dog carried by a plate or arm keyed or
fixed on the shaft c, c as shown at Fig. 5.
The upper end of the vertical shaft actuates the indicating apparatus in the
usual manner.
At or near the foot of the vertical shaft is fixed a disc f, ƒ provided with four
holes corresponding with the four wings or gates of the stile, and a treadle g, g is
provided having a stud h taking into these holes to prevent the stile from being
turned unless the attendant presses his foot upon the treadle, and to prevent the
spindle c, c from being turned round in the reverse direction by means of the stile,
there is a spring bolt beneath the discf, f which also takes into these holes; one
side of the holes and one side of the bolt being bevilled to allow of the spindle
moving round in the direction of ingress only.
Or I fix on the upper end of the shaft c, c a small ratchet wheel k, k (see Fig. 6)
with its teeth set in the reverse direction to those of the ratchet wheel d, d the
pawl k* being fixed to the bottom of the indicator box 1, 1 so that the shaft or
sp.ndle c, c can only revolve in one direction.

page_text: It will be evident that a weight may be substituted for the spring g* which
holds the treadle g g in position against the disc f, f.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be or may be performed I declare
that what I claim is
First. The particular construction and arrangement of the turnstile substantially
as herein before described, so that the same may be used both for ingress and egress
and the indicating apparatus cannot be set back.
Secondly. The connection of the wings a, a of the turnstile to the shaft c, c by
means of a ratchet d and pawl e or their equivalents substantially in the manner
and for the purposes hereinbefore described.
