An apparatus to test the flexure fatigue limits of strips
or fibers of materials is described. The apparatus may
be used to test metals, fibers, paper, polymers and the like
under flexing conditions, and may be adapted to test the
materials in several environments.

The flexure fatigue testing apparatus shown in Figure 3
includes a motor 20 and an eccentric drive assembly 30
mounted on the end of the motor shaft. Motor 20 and assembly

APPARATUS FOR TESTING FLEX FATIGUE OF MATERIALS (Cont'd)

30 are supported upon base member 32 to which is affixed wall
members 26 which form test chamber 10. To drive assembly 30

is connected an oscillating shaft 22 to which samples of ma~
terial 24 to be tested under flex are appropriately secured.
When motor 20 is actuated, drive assembly 30 causes shaft 22
to oscillate, thereby flexing any samples attached thereto,
The samples to be tested and attached to oscillating shaft 22

are secured at the other end by fixed clamp 34, Clamping means
34 is secured in the chamber by threaded rods 28 which protrude
from the chamber wall and which are securely attached to
clamping means 34. Tension of samples 24 may be adjusted or
controlled by manipulation of thre...
