Improvements in Turnstiles.
We, SAMUEL CHARLES BARBER ALDRED, Engineer's Student, of 100, High
Street, and EDWARD FRANCIS DOWNMAN SCUDAMORE, Accountant, of 61, High
Street, both of Rhymney, in the County of Monmouth, do hereby declare the
nature of this invention to be as follows :—
This invention relates to the manner in which we construct and arrange turnstiles
and other like revolving gates or doors whereby an automatic movement of the
gate is obtained by the introduction of a coin into a receptacle or slot which we
provide upon the table or framework of our turnstile or gate.
In carrying our invention into effect when constructing a turnstile suitable for
the passage of persons to any public building or for like purposes-we arrange
preferably four arms or wings, about a central post or pillar, and we cause these
arms to pass between the fixed table of our turnstile, and the centre rail or side
bar, so that one person entering between the arms or wings may pass through at
one movement of a quarter of the complete revolution of the turnstile. Upon the
lower end of the central pillar or vertical spindle we mount or secure a ratchet
plate or ratchet face wheel, having four teeth to suit the number of arms upon
the spindle. This face plate or ratchet wheel we place beneath the bottom bearing
plate which supports and receives the spindle, and we place upon this spindle
between the bearing plate and the ratchet wheel- a key driven or fast ratchet
stopped bush, having four teeth or serrations upon its face. Beneath the bottom
bearing plate we place a bracket, carrying within it a sliding stop, capable of being
lifted by means of a projecting bar or rod which comes in contact with, or is
secured to, a coin operating lever placed also beneath the bearing plate or top
cover of the lower mechanism box of our turnstile. The projecting bar we also
carry forward to engage with the ratchet bush upon the spindle, so that when the
stop is placed in its down or lowest position to prevent the movement of the
turnstile by reason of the tooth of the ratchet face wheel bearing or pressing
against it, then the lifting bar or projecting bar is in its correct position for being
carried up the deep portion of the tooth of the ratchet bush, consequent upon the
lever being moved. While upon the rotation of the spindle after the stop has
been raised out of the line of travel of the top of the tooth, the ratchet bush
tooth gradually depresses the projecting bar ready for a further period or quarter:
of a revolution produced by a like raising of the stop..
The main or coin freed lever we mount upon a bracket carried beneath the
bearing plate or box cover of our turnstile, and we provide it with an extended or
spoon end on to which a coin may drop when placed through a slot in the table
above. The other end of this lever we cause to lift the projecting bar upon the
stop or ratchet bolt, so that when a coin is placed through the slot, the lever is
depressed at one end, while the opposite end raises the bolt or stop.
We employ any well known system of counter gearing or arrangement of wheel
trains to record the number of persons passing through the turnstile and we
construct our turnstiles with arms or passage bars arranged in any well known
manner.

Improvements in Turnstiles.
We, SAMUEL CHARLES BARBER ALDRED, Engineer's Student, of 100 High
Street, and EDWARD FRANCIS DOWNMAN SCUDAMORE, Accountant, of 61 High
Street, both of Rhymney, in the County of Monmouth, 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 relates to the manner in which we construct and arrange turnstiles
and other like revolving gates or doors whereby an automatic movement of the
gate is obtained by the introduction of a coin into a receptacle or slot which we
provide upon the table or framework of our turnstile or gate.
In carrying our invention into effect when constructing a turnstile suitable for
the passage of persons to any public building or for other like purposes-We
arrange our turnstile as shown on the accompanying sheet of explanatory drawings
in which
Figure 1 is a sectional elevation showing one form of arm with bars A on one
side, and another form of arm shaped as a plate or gate B on the other side.
Figure 2 is a detail front elevation and Figure 3 a detail enlarged side elevation
of the stop roller and its bracket.
Figure 4 is a plan of the top ratchet box P showing the ratchet wheel P¹ and
pall for preventing backward movement of the spindle D.
Figure 6 is a plan and Figure 5 an enlarged elevation showing the bottom or
sleeve ratchet box R with the ratchet wheel R' and pall R, for communicating the
rotation of the sleeve S to the shaft or spindle D.
We arrange preferably four arms or wings about a central post or pillar and we
cause these arms to pass between the fixed table C, C¹ of our turnstile and the
ordinary centre rail or side bar, so that one person entering between the arms or
wings may pass through at one movement of a quarter of the complete revolution
of the turnstile. Upon the lower end of the central pillar or vertical spindle D
we mount or secure a ratchet plate or ratchet face wheel E, having four teeth to
suit the number of arms upon the spindle. This face plate or ratchet wheel we
mount upon the bottom bearing plate L which supports and receives the spindle,
and we place upon t
this spindle above the face plate a key driven or fast ratchet
stopped bush F, having four teeth or serrations upon its face. Upon the bearing
plate we place a bracket G carrying within it a sliding stop H, capable of being
lifted by means of a projecting bar or rod J which comes in contact with or is
secured to a coin operating lever K placed beneath the top cover L of the
lower mechanism box of our turnstile. The projecting bar J we also carry
forward to engage with the ratchet bush F upon the spindle so that when the
stop H is placed in its down or lowest position to prevent the movement of the
turnstile by reason of the tooth of the ratchet face wheel E bearing or pressing
against it, then the lifting bar or projecting bar J is in its correct position for
being carried up the deep portion T of the tooth of the ratchet bush F consequent
upon the lever K being moved. While upon the rotation of the spindle after the
stop H has been raised out of the line of travel of the top of the tooth of the
wheel E the ratchet bush tooth F gradually depresses the projecting bar J ready
for a further period or quarter of a revolution produced by a like raising of
the stop. The main or coin freed lever K we mount upon a bracket M carried
beneath the box cover L' of our turnstile, and we provide it with an extended or
spoon end K' on to which a coin may drop when placed through a slot in the table
above. The other end K2 of this lever K we cause to lift the projecting trigger
bar Jupon the stop or ratchet. bolt, or to release the end of the lever J so that
the spring N may pull down the lever thereby raising the stop H after a coin
has been placed through the slot O to depress the lower end K. We provide a

page_text: spring P which can be regulated by nuts for coins of different weights as shown in
Figure 1. We prefer to employ a sleeve or long tube S to fit over the central
spindle D as shown in Figure 1.
We employ any well known system of counter gearing or arrangement of wheel
trains to record the number of persons passing through the turnstile; and we
provide a receptacle for receiving and periodically withdrawing the coins and we
construct our turnstiles with arms or passage bars arranged in any well known
manner.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The construction and arrangement of turnstiles having a coin freed lever to
raise or liberate a stop for permitting the rotation of the turnstile through a
portion of a revolution sufficient to perimit of the passage of one person upon the
falling of one coin on to a lever substantially as herein before set forth.
2. The construction of a turnstile having a stop or roller such as H for
preventing the rotation of the central spindle by means of its contact with a
ratchet wheel such as E substantially as and for the purposes hereinbefore
described and as illustrated in the accompanying drawings.
3. In a turnstile, the arrangement of a lever such as J for engaging with a
ratchet bush or wheel such as F substantially as and for the purposes hereinbefore
described and as illustrated in the accompanying drawings.
4. The construction and arrangement of turnstiles substantially as hereinbefore
described and as illustrated in the accompanying drawings.
