THE IMPROVEMENT OF TURNSTILES, AND APPARATUS CONNECTED THEREWITH "
Year: 1876

page_text: LETTERS PATENT to George Lowry, of Salford, in the County of Lancaster,
Engineer, for the Invention of "THE IMPROVEMENT OF TURNSTILES, AND
APPARATUS CONNECTED THEREWITH
"
PROVISIONAL SPECIFICATION left by the said George Lowry at the Office
of the Commissioners of Patents on the 28th August 1876.
GEORGE LOWRY, of Salford, in the County of Lancaster, Engineer.
IMPROVEMENT OF TURNSTILES, AND APPARATUS CONNECTED THEREWITH."
"THE
This Invention, which relates to turnstiles working in connection with counting
or registering apparatus, consists in improved arrangements and combinations of
parts for enabling the turnstile to be turned either to the right or to the left, and
register either in the one direction or in the other at the will of the attendant.
To attain these objects I employ two ratchet wheels (the one right and the other
left) worked by double or single levers, the wheels being fixed to the lower end of
the vertical shaft to which the arms of the turnstile are fixed, and to the top of
which shaft I fix a star plate with four runners, and 1 employ a T headed holder
acted upon by a spring for the purpose of holding the plate and turnstile arms
steady after each quarter movement, and also to ensure the certainty of the levers
dropping into their proper positions. To the top of the star plate I fix four studs
at equal distances apart, each stud acting on a trigger carried by the end of the
arm or lever projecting from the indicator box, and by reversing the trigger the
indicating arm or lever can be moved in an opposite direction, so that the apparatus
can be made to register either when the turnstile is turned to the right or to the
left. I also make the top and bottom of the revolving arins in two separate
castings fixed on the upright shaft, and I tie them together with a bolt or stud
projecting through the top to form a handle for the convenience of turning the stile
round.

"THE
This Invention relates to turnstiles in connection with counting or registering
apparatus, and consists in improved arrangements and combinations for enabling
tho turnstile to be turned to the right or left and register either in one direction or
the other at the will of the attendant.
To attain these objects I employ two ratchet wheels, one right and the other left,
worked by double or single levers, the wheels being fixed to the lower end of the
vertical shaft to which the arms of the turnstile are fixed, and to the top of the
shaft I fix a star plate with four runners, and employ a T headed holder acted
upou by a spring for the purpose of holding the plate and turnstile arms steady
after each quarter movement, and also to ensure the certainty of the levers dropping
into their positions. To the top of the star plate I fix four studs at equal distances
apart, each stud acting on a trigger fixed to the end of the arm or lever projecting
from the indicator lever, and by reversing the trigger the indicating arm or lever
can be moved in an opposite direction, so that the apparatus can be made to register
either when the turnstile is turned to the right or to the left. I make the top and
bottom of the revolving arms in two separate castings fixed on the upright shaft,
and I tie them together with a bolt or stud projecting through the top to form a
handle for the convenience of turning the stile round.
Fig. 1 is a side elevation, and Fig. 2 a plan view of the improved turnstile.
Fig. 3 is a plan, and Fig 4 a side view of the levers and reversed ratchets shown
detached and half size, and Fig. 5 is a sectional elevation, and Fig. 6 a plan section
showing the mechanism at the upper end of the turnstile shaft detached and on an
enlarged scale.
a the base of the turnstile, in which upright pillars a¹ are fixed that carry the
table a³. In the base, plate a there is a footstep bearing for the turnstile shaft b),
and in the table the upper bearing for the same shaft. In the table as there is a
recess for the counting mechanism. c is the double or reversed ratchet at the
bottom of the turnstile shaft b, c¹ and c² the two levers to be acted upon by the
foot of the attendant. These levers have their fulcrums at c³ and c, and they work
up and down in guides at co and c. The end of one of these levers c¹ acts upon
the teeth of one ratchet at the outside, the other c² upon the teeth at the inside.
At the upper end of the turnstile shaft b a plate d is secured, which carries studs
for four antifrictions bowls d', against cach two of which as they come round the
cross head of a T bolt e rests, which slides at one end in a hole in the recess of the
table, and at the other end in a stud e¹ secured in the table. This bolt e is acted
upon by a helical spring e², which abuts at one end against the recess in the table,
and at the other against a collar or shoulder on the T bolt e; f are four studs
in the plate d, which act upon the counting mechanism; a is the box containing
the counting mechanism of the ordinary kind; g is a lever from the counting
mechanism, which has a ratchet pawl jointed to it that acts upon the counting
mechanism in the box x; his a spring under the box, which acts to bring back the
lever g after each movement. Upon the lever g there is a part i secured by a
screw, which has a pawl that can move to let the studs f pass one way, but
the part i prevents the pawl from moving the other way. When the turnstile is to
count in the reverse direction the box a is slided from one side of the recess in the
table to the other and secured, and the part i is taken from the lever g and put on
it the reverse way so that the pawl or catch will be rigid in the opposite
direction. The arms b¹ and 6 of the 'turnstile shaft bare made in separate
castings connected by bolts b³, the upper end of which formn a stud or handle 6' to
turn the stile.

page_text: I have now particularly described the nature of my Invention, and the mode of
carrying the same into effect, and claim as my Invention the combination and
arrangement of mechanism herein-before described and illustrated by the accom-
panying Drawings for enabling the turnstile to be turned either to the right or left,
and to register in either direction, and the construction of the arms b² and bª, as
described, also the actuation of the counting mechanism by a lever, substantially as
described.
In witness whereof, I, the said George Lowry, have hereunto set my hand
and seal, this Twenty-seventh day of February, in the year of our Lord
One thousand eight hundred and seventy-seven.
