PROVISIONAL SPECIFICATION.
A Lever Flush Folding Turnstile.
I, FRANK OFFEN, of 47, Royal Road, Kennington, S.E., Mechanic, do hereby
declare the nature of this invention to be as follows:-
:-
The object of this invention is to provide an improved method or plan of forming
a turnstile capable of being folded away within the path or passage way of entry or
exit at will, which is effected instantaneously by a hand lever being withdrawn
parallel with the wall acting upon swivel connections and attachments to studs or
pins upon a collar surrounding a perpendicular shaft or spindle,, and at the same
moment acting upon and folding the hinged lever arms and connections hereafter
described, so that they are caused to fall or be withdrawn inwardly from their
relative positions when in use, towards the vertical shaft or spindle; and the action
of the hand lever in folding the projecting lever arms inwardly, at the same time
impels and guides the entire mechanism and carrying frame into a suitable recess
provided within and flush with the wall space.
In the first instance 1 take and form a perpendicular shaft and at about the upper
part of same I provide a boss with projecting lugs and having four arms hinged or
pivotted thereto. At about the mid of the predetermined height of the said vertical
shaft I also provide projecting lugs to same and likewise having four arms similarly
hinged or pivotted to the said projecting lugs. At the extremity of each hinged
arm pivotted to the said lugs of both the upper and mid-centred positions, which
form part of the vertical spindle or shaft-I connect each of the said arms together
with coupling or connecting attachments pivotted to and hinged at both their upper
and lower portions.
I further fit and provide a collar or sleeve capable of freely working in an
upward and downward direction upon the vertical spindle or shaft having four pro-
jecting lugs to each of which angular projecting arms are hinged or pivotted from
same into corresponding lugs cast or formed in or on to the under portion of the
mid centred or lower arms. And immediately under the said collar and sleeve I fit
a further collar upon which when in position support is given to the aforesaid collar
with projecting lugs and arms pivotted or connected to the arms immediately above,
which are suitably hinged and pivotted to the fixed lugs or casting formed upon the
perpendicular shaft.
On each side of the said collar just referred to I provide a pin or projecting-stud
to engage or work freely upon or against a forked arm or lever which works on a
fulcrum provided in the carrying frame and attached by a swivel jointed connecting
rod to a hand lever or connections.
At the top portion of the frame carrying the perpendicular shaft a flap or table
hinged to the frame of the apparatus or wall, bears and supports upon same having
a radial guide or slotted way formed at the under portion so that when it is desired,
by the hand lever action to cause the turnstile to give "clear way," the table or flap
likewise falls flush with the wall space.
In a recess in the upper bearing of the vertical shaft is provided a means to
attach an indicator or counter to be actuated either mechanically or electrically.
And the entire apparatus is provided at the pediment of the shaft with the ordinary
ratchet and stop wheel and foot lever.

A Lever Flush Folding Turnstile.
I, FRANK OFFEN, of 47, Royal Road, Kennington Park, Mechanician, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement :-
The object of this invention is to provide an improved method or plan of forming
a turnstile capable of being folded away within a path or passage way of entry or
.exit at will, which is effected by a lever being withdrawn parallel with the wall
acting upon several connections and attachments to studs or pins upon a collar
surrounding a perpendicular shaft or spindle and at the same moment acting upon
and folding the same and connections, so that they are caused to fall or be with-
drawn inwardly from their relative positions when in use towards the vertical shaft
or spindle and the action of the lever in folding the projecting arms inwardly at the
same time impels and guides the entire mechanism and carrying frame into a suitable
recess provided within and flush with the wall space.
In the first instance I take and form a perpendicular shaft and at about the upper
part of same I provide a boss with projecting lugs having four arms hinged or
pivotted thereto. At about the mid of the predetermined height of the said vertical
shaft I also provide projecting lugs to same, likewise having four arms similarly
hinged or pivotted to the said projecting lugs. At the extremity of each hinged
arm pivotted to the said lugs of both the upper and mid centred positions which
form part of the vertical spindle or shaft, I connect each of the said arms together
with coupling or connecting attachments pivotted to and hinged at both their upper
and lower portions.
I further fit and provide a collar or sleeve capable of working freely in an upward
and downward direction upon the vertical spindle or shaft having four projecting
lugs, to each of which angular projecting arms are hinged or pivotted from same
into corresponding lugs cast or formed in or on to the under portion of the mid
centred or lower arms. And immediately under the said collar and sleeve I fit a
further collar upon which when in position support is given to the aforesaid collar
with projecting lugs and arms pivotted or connected to the arms immediately above
which are suitably hinged and pivotted to the fixed lugs or casting formed upon the
perpendicular shaft.
On each side of the said collar just referred to I provide a pin or projecting stud
to engage or work freely upon or against a forked arm or lever which works in a
fulcrum provided in the carrying frame and attached by a swivel jointed connecting
rod to a hand lever or connections.
At the top portion of the frame carrying the perpendicular shaft a flap or table
hinged to the frame of the apparatus or wall, bears and supports upon same having
a radial guide or slotted way formed at the under portion so that when it is desired
by the lever action to cause the turnstile to give clear way the table or flap likewise
falls flush with the wall space.
In a recess in the upper bearing of the vertical shaft is provided a means to
attach an indicator or counter to be actuated either mechanically or electrically.
And the entire apparatus is provided at the pediment of the shaft with the ordinary
ratchet and stop wheel and foot lever.
For economy of weight and material and for greater elegance of design, I propose
to provide the arms pivotted to the upper boss with a face of polished wood attached
to and overhanging the metal arms.
In the accompanying drawing Figure 1, is a side view of my improved flush
folding turnstile shewing it extended in position and ready for use. Figure 2, is a
front view of same shewing the entire apparatus closed and folded away into the
recess provided, wherein it will be seen by the following letters of reference (which
refer to like or corresponding parts) as to the method of how the action is effected.

page_text: a, is a vertical shaft and at about the upper part of same a boss b, is provided with
projecting lugs c, c, having four arms d, d, hinged or pivotted thereto. e, e, are
projecting lugs with four arms f, f, likewise or similarly hinged to the said projecting
lugs. 9, 9, are connecting attachments pivotted and hinged at both their upper and
lower portions. h, is a collar or sleeve capable of working freely in an upward and
downward direction upon the vertical spindle or shaft a, and having four projecting
lugs, with angular projecting arms k, k, hinged into corresponding lugs 1, 1,
formed in or on to the under portion of the mid centred arms f, and immediately
under the said collar h, and sleeve, I fit a further collar m, which supports the
aforesaid collar, provided with the projecting lugs j, jn, is a pin or projecting
stud to engage or work freely against a forked arm or lever o, working in a fulcrum
provided in the carrying frame p, to a connecting rod q, having a swivel joint r, to
a hand lever or connections s.
At the top of the frame p, carrying the perpendicular shaft a, a flap or tablet,
which is hinged to the frame or wall u, and supported thereby; a recess v,
is pro-
vided in the upper bearing of the vertical shaft to contain an indicator or counter
which by means of tappet pins projecting from the boss b, into the recess v, may be
actuated or worked either mechanically or electrically. The entire apparatus is
provided at the pediment of the shaft with a ratchet or stop wheel w, and foot
lever x.
Figure 3 is a plan of a portion of the apparatus for withdrawing the carrying
frame P into the recess provided in the wall, effected by the movement of the hand
lever which engages
S,
with the pin s', in the slide y, and is connected by the rod ³,
to the folding arms, z, causing them to be withdrawn into the closed position as
shewn in Figure 4.
I may in some cases propose to extend the carrying frame p, so as to adapt the
apparatus to the width of any passage way and fill in the intervening space between
the pillar of the upright carrying frame p, and the connecting attachments 9,9 with
a railing. Also as an alternative method of moving the carrying frame p, to dis-
pense with the hinges p', and the connections as shewn in Figure 3, and cause the
carrying frame p, to slide in grooves suitably disposed, either parallel with or
angularly disposed to the wall; and also substituting for the catch or latch p,
which retains the lever s, in its forward position a stop på, for the purpose of
retaining the lever o, and attachments in the erect position as in Figure 1.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
1. That by my invention for an improved lever flush folding turnstile to effect
my particular purpose or method of folding away same within a path or passage
way by means of a lever and levers or connections acting directly upon the
mechanism proposed as in combination without the intervention of springs to effect the
particular purpose herein referred to.
2. I may further propose to slightly modify or alter the mechanical arrangements
for the particular object and purpose to secure the convenient disposition of the
apparatus by causing the carrying frame to slide in grooves or guides or by other
suitable means and in manner herein referred to and described.
Dated this 14th day of March 1891.
