What do a Model-T Ford, a
movie projector, a supermarket register, and
an early twentieth century textile mill have
in common? No, this isn’t some sort of
joke. Rather, the answer is the subject of
this month’s Yankee Ingenuity column.
Most people know that the
first part of the American Industrial Revolution
was powered by water and that New England’s
early mills were built on or near rivers so
that they could harness the power of moving
water to drive the machinery used to automate
manufacturing tasks. However, many people do
not understand how water was actually used
for this purpose. In fact, I must admit that
I did not fully understand this process until
I recently accompanied my oldest daughter on
a school field trip to the Belknap Mill.
Traditional water powered
mills used a flow of water to turn a water
wheel or turbine that was attached to a shaft.
The turbine shafts in textile mills were coupled
to large gears that transferred the power from
the turbine shaft to a large central drive
shaft, which turned chains and/or belts that
transferred the power to other parts of the
mill where it was used to drive the machines.
In many mills, including the Belknap Mill in
Laconia, endless belts were the primary means
for transferring this power. In these mills,
large flat belts were stretched between the
central drive shaft and smaller "line shafts" in
other parts of the mill. Smaller endless belts
were then stretched between the line shafts
and the machines themselves. The stretching
of the endless belts between the shafts created
the friction necessary to engage the shafts
such that the turning of the central drive
shaft caused the large endless belts to rotate.
The rotation of the large endless belts rotated
the line shafts, which in turn rotated the
smaller endless belts attached to the machines.
This use of endless belts
to transmit power survived the change from
water turbines to steam engines as the primary
sources of power, and the later change from
steam engines to modern internal combustion
engines and electric motors. In fact, endless
belts are currently used in a vast array of
products including automobiles, motion picture
projectors, supermarket registers, and vacuum
cleaners, to name but a few. (Hint: This is
the answer to my riddle).
Endless belts were traditionally
manufactured from strips of leather that were
sewn together. Unfortunately, these belts were
prone to stretching and the friction between
the shaft and the belt would cause the leather
to become smooth over time, each of which resulted
in slippage of the belt. In response to these
problems, leather belts began to be replaced
by belts using fabrics that were coated with
India rubber. This change occurred at least
as early as 1857, when Robert Hale of Roxbury,
Massachusetts was granted U.S. Patent No. 17,216
for his machine for making India rubber belts.
As time went on, different
materials and methods were utilized in the
manufacture of endless belts. Further, the
use of endless belts had expanded beyond their
traditional use in manufacturing processes
and they were used extensively in other applications,
including many in the fledgling automotive
industry. In fact, the manufacture of belts
for the automotive industry was the first order
of business for the Arthur S. Brown Manufacturing
Company of Tilton, New Hampshire.
Arthur S. Brown was a young
telegrapher for the Boston and Maine Railroad
when he arrived in Tilton a few years before
the turn of the century. He fell in love with
a local woman, Belle Peabody, whom he married
in 1898, and became associated with Tilton
Woolen through his wife’s family connections.
In 1912, Mr. Brown opened his own company and
began the production of endless belts for use
in automobiles. At that time, Mr. Brown’s
company produced flat endless belts and Mr.
Brown nearly went bankrupt during his first
years in business. However, the fortunes of
Mr. Brown and his company would be forever
changed by his Yankee ingenuity and the ingenuity
of his employees.
Ludovic Shiatte went to work
for Mr. Brown in 1916 as a shop worker and
eventually advanced to the position of overseer
and plant superintendent. In 1922, Mr. Shiatte
began work on the design of an endless belt
that would have no stretch to it. He collaborated
with Mr. Brown and the company’s bookkeeper,
Gertrude Knapp, in connection with his design
and the culmination of their work was the endless
power transmission belt described in United
States Patent No. 1,545,206, which issued on
July 7, 1925.
The endless power transmission
belt of Patent No. 1,545,206 was manufactured
by forming a loop having a desired size from
a strand of twine, string or yarn and then
winding another strand of string or yarn around
the loop until the body of the belt was built
up to the desired size. The key to this winding
operation was to maintain a constant tension
on the strand being wrapped around the loop
so that the entire body of the belt would be
under uniform tension. Once fully wound, the
body was wrapped with a tape covering and stitched
together in a certain manner in order to obtain
the desired shape. If a belt having a round
cross section were desired, the belt would
be stitched transversely at a number of locations
around the belt. If a belt having a v-shaped
cross section were desired, the belt would
be stitched at only three locations so as to
form a triangle.
The belts produced by the
Arthur S. Brown Manufacturing Company came
to be known as Tilton Endless Belts and were
used extensively by Henry Ford, most notably
in the Model T. In fact, it was rumored that
Ford was so impressed with the belts that he
wanted to buy the company. Mr. Ford visited
Tilton in the 1920’s along with two similarly
famous traveling companions; Thomas Edison
and Harvey Firestone, and toured Brown’s
factory. It is ironic that Ford later ended
his relationship with Mr. Brown when Firestone
starting making rubber V-belts. However, the
relationship did help to reverse the fortunes
of the Arthur S. Brown Manufacturing Company.
Mr. Schiatte, who continued
to work for the company until his death in
1947, was co-inventor of another invention
with Mr. Brown and Ms. Knapp, who married and
became Gertrude Sedgley. Mr. Brown continued
to innovate and to collaborate with Mrs. Sedgley
on innovations to endless belts until Mr. Brown’s
death in 1957. This collaboration resulted
in the issuance of a number of other patents
directed both to round belts and flat belts
and their inventions helped the company to
develop into a successful worldwide business.
