Stoelting
Cardio-Pneumo Polygraph
|
| Stoelting Cardio-Pneumo Polygraph |
This instrument was manufactured in the early 1950's. It was a self
contained, portable instrument, weighing approximately 25 pounds. It was designed to record accurately blood pressures and
respiration on a six inch graph which moved at a standard rate of speed. The pens were made of stainless steel, which made
them practically a fool-proof recording pen because they were non-corrosive. The motor operated directly on 120 volt, 60 cycle
current. The instrument was very sensitive and it's rugged construction offered many years of continued service.
This instrument is not in the Polygraph Museum's collection.
Stoelting's First
Deceptograph
|
| Stoelting's First Deceptograph |
Manufactured in the early 1950's, this was the first of Stoelting's
"Deceptograph" line. It was a three channel instrument consisting of a pneumograph, a cardiograph, and a galvanometer. It
weighed 40 pounds and measured 22" long, 11" wide, and 14" high. It used jeweled bearings and precious metal divots for all
recording pens. Each pen was equipped with a counterweight to delicately balance the pen over the paper. The kymograph ran
a 6" or 12" per minute, selectable by the examiner. It ran on both 120 volt, 60 cycle current or batteries.
This instrument is not in the Polygraph's Museum collection.
Deceptograph
Stoelting Model #22500
|
| Deceptograph |
Manufactured between 1955 and 1960, the Stoelting Model #22500 “Deceptograph”
was the latest in polygraph design for it’s time. It featured three modules; one pneumographic component, one
cardiographic component, and a GSR component consisting of an amplifier and a galvanometer.
Another feature of this particular Deceptograph is a concealed microphone.
You will find it on the pneumo module on the far right. Under this fake knob are four small holes to allow sound into
the microphone concealed beneath the face plate on the instrument.

Deceptograph
Stoelting Model #22500
|
| Deceptograph |
Like the instrument above, it has three components: a cardiogaph,
a pneumograph, and a galvanometer. It has a three pen community inking system, and a six inch kymogaph.
Towards the bottom on the instrument are two large doors. The one on the left is a storage
cabinet for the GSR, pneumo, and cardio attachments, as well as ink and other supplies. The compartment on the right is for
the galvanometer. It is so large because the galvanometer was powered by large vacumn tubes. This instrument was used before
the age of transistors.

| Deceptograph |
Like the two Model #22500's above, this Model #22500 had a galvanometer powered
by vacuum tubes, which required a thirty minute “warm-up” period before each test.
Weighing in at over forty pounds, this instrument was remembered
by all who used it a similar to carrying around a large rock. The bulk of it’s weight came from the GSR unit.
This particular instrument has been modified to accept a three bottle
capillary inking system in addition to the community inking system standard with this instrument. This modification
was probably done by the examiner himself.

| The Truth Verifier |
Affectionately known as the “Octopus,” this Stoelting
Truth Verifier was altered to include six channels. It was used primarily as a laboratory instrument by psychologists.
But it also used by polygraph examiners.
It is equipped with six separate recording modules utilizing two
separate three pen community inking systems. It gained it’s nickname when one polygraph examiner claimed that
you “had to have eight arms just to keep the pens centered.”

The Bowling Ball
Stoelting Interrograph
|
| The Stoelting Interrograph |
Touted as the smallest polygraph instrument ever made, this three
pen Stoelting instrument has everything it’s larger brother’s had. Affectionately called “the Bowling
Ball” by examiners due to it’s size and similarity to a bowling ball bag when carried.
Originally purchased in 1960 for $900 by Lincoln M. Zonn it was
used between 1960 and 1985 when it was finally retired. It was designed by Joe Hager, the owner of the Stoelting Instrument
Company due to the demands by polygraph examiners for a lighter instrument. It was discontinued because test subjects
considered them “toys.” Less than 100 were manufactured.
An instrument similar to this was used to test Jack Ruby regarding
the murder of Lee Harvey Oswald following the Kennedy assassination. The examiner was Phil Herndon of the FBI. He verified
that Oswald was not part of a conspiracy to assassinate the President.

| Cardio-Pneumo Polygraph |
This two channel “cardio-pneumo polygraph” was introduced
by the C. H. Stoelting Company in the mid 1950's to compete with Keeler’s Model 6308 three pen polygraph instrument.
Nicknamed the “Tackle Box” by examiners due to it’s
resemblance to a fishing tackle box when closed, it was small and light to carry. This particular instrument was used
by the McKesson-Robbins Drug Company in it’s Hawaii offices.

| Stoelting Model #22490X |
This instrument is a hybrid between a Model #22500 and a Model #22600.
It is equipped with one pneumograph and one cardio graph. It has a six inch kymograph.The modules themselves appear to come
from a Model #22500, but it encased in a Haliburton case similar to a Model# 22600. It is a custom made instrument.
It was donated by Norman Matzke, King County Sheriff's Department.
Early Stoelting Polygraph
|
| Custom Made Polygraph |
This instrument was hand made by C. H. Stoelting after his retirement.
Polygraph Examiners with specific requirements in instrumentation, contacted C. H. Stoelting after his retirement and requested
hand made instruments made to their specifications. This instrument is enclosed in a large mahogany case, with a utility
drawer in the lower portion to store attachments, ink, paper, and spare parts.
It contains two pneumographs, one cardiograph, and a stimulus marker.
The inking system consisted on four small open reservoirs. It is a one of a kind instrument. It’s original
owner is unknown.

Emotional Stress Monitor
Stoelting Model #22600
|
| Stoelting Model #22600 |
The Stoelting Company pioneered many of the features that are regarded
as standard today --modular construction, friction chart drive, simplified inking systems and rugged, yet sensitive recording
sections.
The Stoelting Model #22600 was a pioneer in polygraph instrument
construction. It contained three channels; a pneumograph, a cardiograph, and a galvanograph. Each was mounted
in the face of the instrument in modules which could be easier removed for repairs or replacement. These modules were housed
in a metal case equipped with a six inch kymograph, and community inking system.

Emotional Stress Monitor
Stoelting Model #22608
|
| Stoelting Model #22608 |
The Model #22608 was introduced in 1966. It was identical
to the Model #22600 with the exception of the second pneumographic module. It introduced a kymograph with eight inch
paper. A real improvement over the six inch paper before. This simple but rugged instrument soon became the favorite
of U.S. Government examiners.
This particular Stoelting 22608 was the primary instrument of Terry
R. Tanner. It has been equipped with ink loaded pens which allowed an examiner to use these older model instruments
well into the 1980's by replacing the need for the messy community inking systems.

The Model #22608 was introduced in 1966. Notice the red
wheel on the left side of the instrument resting on the paper. This was the friction drive for the kymograph. It replaced
the older sprocket drive on the Model #22500.
It’s biggest customer was the United States Armed Forces.
This instrument, and other like it, were used by U.S. Army, Air Force, Marine and Navy polygraph examiners as their primary
polygraph instrument for many years to come.

| Stoelting Multigraph |
In the early 1950's, there was a trend in the polygraph industry
to move the polygraph instrument into the laboratory. Examiners began to wear white lab coats.
The Multigraph was created to meet the needs of these examiners.
A large desk top model, consisting of two pneumographs, a galvanometer, and two cardiographs, it looked like a piece of laboratory
equipment. It quicky fell out of favor in the polygraph community due to it’s lack of mobility.

| The Arthur IV |
The Arther IV Polygraph was the fourth model built for Dick Arther
by various manufacturers for sale. Built between 1972 and 1982, it featured five channels; two pneumographs, one cardiograph,
one galvanograph, and the fifth channel which was an event marker.
Dick Arther asked that the event marker be added to his instruments
after seeing one on a Berkeley Psychograph. The event marker is the channel at the top of the module console.

Executive Polygraph
Stoelting Model #22532
|
| Executive Polygraph |
A three pen portable polygraph instrument. It was manufactured
between 1965 and 1970. It’s uniqueness lies in the fact that it will run on re-chargeable batteries. With
it’s built in battery charger, battery power meter, and it’s Samsonite Attache Case, it allowed the traveling
polygraph examiner to truly take his instrument anywhere.
It was a favorite instrument for testing gold miners and diamond
mine workers as it could be taken right into the mine.

Polyscribe
Stoelting Model #22770
|
| Polyscribe |
Introduced in 1974 and discontinued in 1979, the “Polyscribe”
was touted as the “Ultimate Polygraph.” It featured dual functionality by each of four modules that were capable
of handling both pneumographic or electrical inputs. Before this innovation of selectable functions, each module in
a polygraph instrument had a specific purpose.
The GSR system incorporated “Solid State” components
which allowed more circuitry below the circuit board to enhance the GSR functionality.

| 4 Channel UltraScribe |
Introduced in 1979, the “Ultrascribe” is still Stoelting’s
top of the line analog polygraph. The original Ultrascribe was a four channel, all manual instrument as depicted here.
It allows the maximum in flexibility for the modern polygraph examiner.
This instrument had two pneumographs, a galvanometer, and one cardiograph.
This is an all mechanical instrument.

Introduced in 1979, the “Ultrascribe” is still Stoelting’s
top of the line analog polygraph. The second edition of the Ultrascibe was electronically enhanced. it allows the maximum
in flexibility for the modern polygraph examiner. It can handle up to five separate, selectable modules, including a CAM function,
movement sensor function, and stimulus marker function.
This instrument is still the top of the line in analog polygraph
instruments offered by the Stoelting Company. It is an all electronic instrument.

Executive UltraScribe
Stoleting Model #81500
|
| Executive UltraScribe |
The same polygraph instrument as the Ultrascribe above, except housed
in a small briefcase for the polygraph examiner “on-the-go.” It can handle up to five separate, selectable modules,
including a CAM function, movement sensor function, and stimulus marker function.
This particular instrument is equipped with a “GSR Meter.”
This meter was to be used during interrogations to alert the interrogator to a subject’s concern about an issue. The
meter, consisting of a small blue light bulb, plugged into the GSR RCA jack. As the subject's galvanic response
changed, the bulb would glow brighter or dimmer. It was thought that this meter would help improve the quality of the control
and relevant questions.
