Improvements in Turnstiles.
I, BARON STAATS VON MUNCHHAUSEN, of Hannover in the Empire of
Germany, 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 improvements in turn-stiles, and consists in arranging
the said turn-stiles, that the outstanding arms are made to rise and fall, into and
out of position, as the same are turned or rotated.
The arms of the turnstile, may consist of single projecting bars or arms, or they
may consist of a series of connected arms, jointed together after the manner of
Lazy tongs" or "Nurnberg scissors."

The object of the invention is principally to economise space, and to render more
simple and efficient the said appliances.
When the turnstile is in use, the arms are lifted prior to closing the passage,
and remain so while passing through the stile, and are then subsequently lowered
again.
Figure 1 of the accompanying drawing, represents in part section and part
elevation, a turnstile constructed according to my invention, with a gate or arm
part made up of a series of jointed rods, which contract, and open out vertically,
through the intervention of a short arm connected to one of them, which traverses
against a cam shaped incline, directed horizontally, and which is shown open or
spread out, as in Figure 2.
Figure 3 is a horizontal cross section, and Figure 4 is another view of the cam
shaped incline.
Figure 5 is a vertical section of another form of turnstile, constructed according
to another form of my invention.
to
Figure 6 is a vertical section of a further form of turnstile, constructed according
my invention, and Figure 7 is a horizontal cross section of Figure 6.
Figure 8 represents another form of turnstile, with outer top bar, and with the
operating mechanism differently constructed and arranged. Figures 9 and 11 are
cross sections of the same, while Figure 10 is a topside plan.
Figure 12 is a side elevation of a part of the appliance, showing the channelled
incline or cam, through the intervention of which, the arms are raised or lowered.
Figures 13 and 16 represent different views of a further form of my invention,
whilst 14, 15, 17, 18, 19, and 20, are parts of the same, with Figure 19 shown upon
an enlarged scale.
The turnstile with movable arms, has the property that these arms, to save space,
are lifted shortly before shutting the passage, remain lifted while passing through
the stile, and are afterwards lowered again. The arms may consist of a single rod,
or be arranged like the "Nurnberg scissors," the following mechanism, actuated by
curved grooves, after the manner of cams, being applicable to both.
The drawing shows the various arrangements of the mechanism, the arms being
arranged after the fashion of "Nurnberg scissors.".
In Figures 1 to 4 S is an erect pillar, round which turns the cylinder or hollow
casing H, together with the arms R, which a pivoted in the lugs Ho. The pillar H,
is supported by means of the pin ½, resting in the bearings', in the head S³, of
the pillar S, while the lower edge H³, comes against and turns upon S¹, as a
collar.
The vertical movement of the arms, occurs as follows :—
11

page_text: Figure 2, in which a, b, is the top, and c, d the bottom edge of S. Underneath
the projection formed by this curve, sec horizontal section in Figure 3, slide the
ends R' of the rods R, these being in the raised position on the left, Figure 1,
when R', is under the part 1, g', of the curve, while the rods hang down, when
passing the parts e,, and y', h, of the curve, as in Figure 1 on the right. On turning
the pillar H, in the direction of the arrow, Figures 2 and 3, the part f, g of the
curve, causes the elevation, and the part y¹, h, of the curve, the depression of
the arms, these parts being designed according to the desired motion of the arms.
In the arrangement shown in section in Figure 5, the rod l' is elevated in the
same manner, as in the former arrangement the rod R. The pillar S. here becomes
a rigid support for the pillar H, the bell shaped projection H', of which, fits over
the head S, of the pillar S, and carries the rods P, which are pivoted in the lugs h¹.
The arrangement of the curve, for the movement of the ends P₁, of the rods P, is
the same as in Figures 2 and 4.
The movement is transmitted from P to R, through the rod Q, the arms being
completed by P³, and Q.
The arrangement shown in Figures 6 and 7 in vertical and horizontal section,
differs from Figures 1 to 4, inasmuch as the ends R', of the rods R, are connected
by rods, to levers T. T₁, which are pivoted in. the lugs ° on the pillar H, the
ends T, being actuated by a curve similar to Figure 2, which may be a groove or
projection, and which is situated on the part S, of the foot of the pillar. A pro-
tective covering D, encloses the mechanism.
The movement of the levers, according to the form of the curve, is transmitted
through the rods t, to the arms. The rods P and Q, shown in Figure 1 as being
movably jointed, are left out in Figure 6.
The Figures 8 to 12, shows the application of a slide N, guided at S', and S, by
slides, having above a horizontal groove n, and below a groove n¹, this being curved
to obtain the desired movement of the arms; see the elevation Figure 12.
The ends P¹, of the rods P, are led in the groove n, while the pins M, in H,
engage in the groove n¹, P1 and M entering their respective grooves at the same
time on turning the pillar H.
This causes first a downward movement of N, then rest, and afterwards an upward
movement again. This movement is transmitted to the arms through the rod P,
the same, in this instance, being raised through an angle of 45° only.
If it is desired that the arms lift quickly, that is, for a small turning of H, an
auxilliary force can be employed.
If one connects any two opposite arms R by the springs F, which pass through
holes in H', see Figure 11, and imagine instead of the slide arrangement in Figure 8,
the arrangement as shown in Figure 5, for raising and lowering the arms, then,
when the rod P, (on the right) is depressed on turning H, the rod R, will also be
depressed, and the spring F, compressed. The end P', on the left, presses against S³,
and P can only be raised when the part P'enters the part f, g, of the curve, whereby
the spring, expands to the left, and on the continued turning of H, causes the
elevation of the rods P. R. Q (on the left), cither alone, or in conjunction with
curve, the rate of clevation depending on the angle of f, g.
The spring F, can also be inside, as drawn in Figures 13 to 15. Here the
ends P', of the rods, are led in the curved groove in the head S', of the pillar S.
In S¹, is a slots, in which fits the plater, see section Figure 13, and clevation
Figure 14, having a horizontal groove y, and a rod Z, that is guided in the foot S'.
Cn Z, is the ring, which can only be turned horizontally on the rod, with the
pins Over Z is passed the spring F, being compressed between the pillar
head S', and the ring, and the ends secured in these places only. In the position.
shown in Figure 13, lies in the vertical grooves', of which the horizontal groove.s",
is a continuation, see the part section Figure 15.
Further, there are in H, four pins M, which are situated under the four rods P.
In Figure 13, the rod.P, (on the right) is in the highest position, and. P¹, in

page_text: part of the curve Figure 2, as well as in the groove y. As soon as P, through
turning H, enters the part g', h, of the curve, a will be lifted by P', and the spring F,
compressed. Since the bottom end retains the tension which it has previously
received through turning, on Z, the pin ³, being in the groove s', will, at the
highest position of P¹, that is the lowest position of P, Figure 13, enter the hori-
zontal part so of the groove, and hold the plate, and the compressed spring F,
fast. Now, on turning H further, the end P¹, of the next following rod P, enters
the groove y, the corresponding pin M, strikes against the pin 2, Figure 15, and
draws 23, out of so. The spring F, pressing upon 2', drives the rod Z, as well as x
and P, downwards, and P out of the vertical position on the left (Figure 13) into
the inclined position on the right. If it is too difficult, by merely turning H, to
compress the spring F, a lever can be arranged to lift the rod Z, from some outside
force, not in connection with the rotary motion.
In Figures 16 and 17 in cross and horizontal section, in Figure 18, elevation, and,
in Figure 19 on a larger scale is shown the above described arrangement for the
affixing and release of the spiral spring F, as well as the use of the slide N', the
upper and lower plates N and N', being connected by the rod Z, upon which is
the spiral F, and the ring, with pins ³, and a³.
The pins M cut here on the angle of 23, otherwise the action is the same as in
Figures 13 to 15.
In order that H can be turned in one direction only, a ratchet is provided, which
in Figure 1 for example, consists of an inner tooth wheel 2 on H, in which engages
the catch K, situated on the head S' of the pillar, and actuated by the spring K'.
It is obvious that H can then be only turned in the direction of the arrow.
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 :-
First: A turnstile, having a hollow pillar, or upright, and turning upon a
central fixed one, and carrying outstanding jointed arms or rods, or jointed rods,
constituting the gate, and which gate, rises and falls, or both rises, falls and
collapses, as the said hollow pillar is rotated by being turned, on persons passing
through the stile, substantially as described and set forth.
Secondly-In a turnstile, imparting or giving to the arm or arms, constituting
the gate, or stile, a rising and falling, or a rising, falling, and combined collapsible.
movement, by a short arm or arms of the said gate or stile, traversing within a
curved channelled slot, or against a cam shaped projection or guiding curve,
carried upon a portion of the fixed pillar, so that as the stiles rotate, the gate or
gates of them are taken into, and out of position, substantially as described and
set forth.
Thirdly-Making the gate parts, of jointed and connected rods, after the manner
of "Lazy tongs" or "Nurnburg scissors," substantially as set forth in Figures 1,
2, 5, and 8.
Fourthly In turnstiles, raising and lowering, or collapsing the jointed rod or
rods, constituting the gate or stile, through the combined intervention of guiding
curves and springs, substantially as described and set forth in Figure 8.
Fifthly The improvements in turnstiles, as described and set forth in Figures 1,
2, and 3, and the parts of which are arranged, combined and act, substantially in
the manner, and for the purpose as set forth.
Sixthly In a turnstile, the general construction and arrangement and move-
ment of the parts of the said appliance, as described and set forth in Figure 5.
Seventhly:-In a turnstile the construction, general arrangement and combination
of the parts, as set forth in Figures 6 and 7.
Eighthly-In a turnstile, the construction, general arrangement and combination
of the parts as set forth in Figures 8, 9, 10 and 11.
Ninthly -The improvements in the construction of turnstiles, that is to say,
