Morris' son Dierre Smith and his
 father's triphammer
.
Triphammer 3
The working components: The
 hammer and anvil.
Triphammer 4
The hammer is made up of iron
 pieces riveted and bolted
 together. It slides up and down
 in a reinforced piece of channel
 iron.
Triphammer 5
The anvil is a short section of
 railroad track.
Triphammer 6
The hammer rebounds with such
 force that it is necessary to
 cushion it with a valve spring
 from an old truck.
Triphammer 7
The hammer swings on arms
 fabricated from scrap iron.
Triphammer 8
A section of a truck's crankshaft
 and a connecting rod provide
 the reciprocating action which
 moves the hammer.
Triphammer 9
The triphammer is powered by
 an electric motor from a gas
 pump which is sealed to
prevent sparks. Originally,
 it was powered by a belt from
 a line shaft.
Triphammer 10
The motor generates 1/6 hp at
 1725 rpm.
Triphammer 11
The clutch is an idler pulley
 which tightens the flat belt.
Triphammer 11
A rod from the idler pulley is
 connected to an adjustable foot
 pedal.
Triphammer 13
When the foot pedal is released,
 a spring releases the tension on
 the idler pulley and allows the
 belt to slip.
Triphammer 14
The trip hammer was constructed
 with gas welds which are still
 sound after three-quarters of a
 century.
Triphammer 15
A heavy rod reinforces the frame
 against the incessant pounding
 of the hammer against the anvil.
Triphammer 16
The trip hammer is bolted to a
 concrete block which was buried
 in the ground.
Triphammer 17
The trip hammer is now exhibited
 by the Antique Power Buffs.
Triphammer 18
The trip hammer eliminated
 much arduous labor and
 increased productivity.
