APPARATUS FOR OPERATING MOVABLE
MEMBERS‘
George Efron, New, York, N. Y.
Application November 4, 1936, Serial No. 109,141
In Germany November 6, 1935
3 Claims.
My invention relates to an apparatus for oper
ating movable articles or ?gures, for instance dis
play articles and figures such as described in my
co-pending application for patent of the United
5 States, Ser. No. 18,558, ?led April 27, 1935, for an
“Apparatus for operating movable members”.
As described in my co-pending application, the
articles and ?gures are equipped with movable
limbs and bellows for moving the limbs and/or
10 they are mounted to move on a suitable support
and operatively connected to bellows for moving
them on the support. The bellows for moving the
limbs and the bellows, if any, for moving the com
plete articles or ?gures are controlled by pneu
15 matic means such as a tracker bar and a per
forated control sheet.
It is an object of my invention to provide an
improved apparatus for operating movable arti
cles or ?gures. To this end, in combination with
20 a tracker bar, pipe lines connecting the tracker bar
to the individual controlling means, for instance
the bellows referred to, by which the movable
parts of the articles or limbs of the ?gures, and/or
the articles or ?gures themselves, are operated,
25 a control sheet and means, such as a pair of reels,
for moving the control sheet across the tracker
bar, I provide a source of potential energy, for
instance a source of compressed or rare?ed air,
which is connected with the rest of the apparatus
30 in such a way as to provide an integral whole.
In the preferred embodiment of my invention I
provide, that the bellows and the other means
providing air compression or air rare?cation lie
in the same air-tight compartment as the tracker
35 bar, the control sheet and the remaining im
portant parts of the set up.
In that way I reduce the size of the whole appa
ratus, achieve greater efliciency of the same and
reduce the production costs.

In the drawing affixed to this speci?cation and
forming part thereof, the apparatus embodying
my invention is illustrated diagrammatically by
way of example.
In the drawing:

Figs. 1 to 4 illustrate the apparatus, operated
by compressed air.
More particularly:

ratus.

Fig. 2 shows the opened apparatus, i. e. the
apparatus with its lid taken off.
Fig. 3 shows the interior of the apparatus, the
reels with the control sheet having been removed.

(Cl. 46—120)
. Referring to the drawing: I is a box mounted
on suitable feet 2. The lid 3 is the front part of
the box which is hermetically closed by means of
screws 4. Lid 3 is equipped with the pipes 5, ex
tending to the bellows, or other pneumatic means
of the articles or ?gures, to be operated.
In the interior of the box I are the bellows 6,
which are connected with the eccentric 9 by means
of the angles ‘I and the flexible parts 8. Eccentric
9 is placed on the shaft II] which is being driven 10
by the wheel II. When this wheel II is put into
motion by an electrical motor, the bellows 6 open
and close in turn and in this way suck the outside
air through the openings I2 and pump it into the
15
interior of box I through the valves I3.
On the inner side of lid 3 is placed the tracker
bar 24 into which the ends of the pipes 5 are in
serted. Past this tracker bar 24 the control sheet
I6 is stretched, running over the reels I4 and I5.
These reels are mounted to rotate at I4’ and I5’ 20
one of the reels (I5) being connected to the shaft
ID by means of a pair of bevel gearing I8 and I9,
the’shaft 20, the sprocket 2|, the chain 22 and
sprocket 23.
When the shaft I0 is put into mo
tion, its motion is transmitted to the perforated 25
sheet I6, so that simultaneously with the move
ment of the bellows 6 i. e. with the creation of air
pressure in box I, the control sheet I6 is also put
into motion. During this motion the perforations
I‘I glide by the openings of the pipes 5 and con 30
nect or disconnect them from the interior of the
box I. Namely, should one of the perforations I'I
coincide with one of the pipe-openings, then the
air flows out of box I through the connected pipe
5 into that part of the object or ?gure, to which 35
that particular pipe leads. On the other hand
should the solid part of the perforated sheet I6
cover the opening of the pipe 5, then the air cur
rent in the pipe 5 is interrupted and therefore the
motion of the objects connected to pipe 5 stops. 40
To each vertical row of perforations corresponds
one of the pipes 5, so that the changes in air pres
sure in every separate pipe 5 can be controlled by
the position of the perforations on the control
sheet. The length of the perforations corre 45
sponds to the duration of the particular movement
in question. The width of the perforation corre
sponds to its intensity. In this way I can con
trol and vary the movements of the objects or
?gures, moved by air pressure created by bellows 50
or other pneumatic means. Instead of air pres
sure I can also use air rare?cation for the same
purpose.
I claim:

bers, a distributor casing, a tracker bar in said
casing having passages opening into said casing
at one end and connected to control pipe lines at
the other end, a control sheet in said casing, means
for moving said control sheet past the open ends
of said passages so as to make and break their
connection to the interior of said casing, and
means in said casing for producing in its interior
air pressure other than that of the atmosphere.

2. In an apparatus for operating movable mem
bers, a distributor casing, a tracker bar in said
casing having passages opening into said casing‘
at one end and connected to control pipe lines at
the other end, a control sheet in said casing, means
15 for moving said control sheet past the open ends
of said passages so as to make and break their
connection to the interior of said casing and
bellows for producing an air pressure other than
that of the atmosphere, which bellows are driven
by the same shaft as that which drives the control
sheet.
3. In an apparatus for operating movable mem
bers, a distributor casing, a tracker bar in said
casing having passages opening into said casing
at one end and connected to control pipe lines at
the other end, a control sheet in said casing, means 1O
for moving said control sheet past the open ends
of said passages so as to make and break their
connection to the interior of said casing and a
mechanical connection between these means and
the shaft which drives the bellows.
