Toward the latter part of the following week, Frank was ready to give
the product of his labors its first road trial. On September 21 the
completed carriage was rolled onto the elevator at Russell's shop.
Seeing that the running gear was too long for the elevator, they raised
the front of the machine, resting the entire weight of 750 pounds on the
rear wheels. Once outside the building, they pushed it into an area
between the Russell and Stacy buildings. After dark, "so no one will
see," Will Bemis, Mr. Markham's son-in-law, brought a horse and they
pulled the phaeton out to his barn on Spruce Street.[28] There, on
Spruce and Florence Streets the first tests were made. The next day
Frank wrote his brother saying, "Have tried it (the carriage) finally
and thoroughly and quit trying until some changes are made. Belt
transmission very bad.[29] Engine all right." He did admit the engine
seemed to be well loaded most of the time. He also had an idea in mind
to replace the poor transmission, explaining the plan to Charles: "The
three gears[30] on secondary shaft have friction clutches, the two bevel
gears on same shaft are controlled by a clutch which frees one and
clutches the other at will. This provides a reverse."

The _Springfield Evening Union_ of September 22 carried a notice of the
trial. This report, too, commented on the faulty transmission and the
plan already in Frank's mind for the new transmission.

... The friction belt allowed of the speed being steadily increased
or diminished at the will of the driver and caused no sudden
forward motion of the carriage, but while this arrangement has many
advantages it uses up the power so that the two-horse pow
