out, its legs 2 opened out as seen in full lines
in Fig. 1, its gate opened, and the line L
- passed through the open gate between the
faces of the wheels. The frame is now stood
5 with its feet on the floor boards the gate
closed and latched, and, the thumb nut ad-
justed so that the line is. gently clamped be-
tween the two wheels. Now the well ma-
chinery is operated -to pay out on the line
10 L rapidly. As it passes between the wheels,.
both rotate, and as the wheel 11 makes one
rotation for each foot of line going past it,
the computer or register is actuated accord-
ingly. When the tool strikes the bottom of
15 the well, a proper computation can be made
to ascertain the depth" of the well, if it be
an oil well, in a manner which will be'clear.
The wheel 16 is now retracted, the gate
opened, the instrument removed entirely
2: from the line, its legs 2 folded and latched,
and the entire apparatus put away for future
use; and thereafter the ordinary function of
the -well machinery may be carried on with-
out interruption.
What I claim as new, is- 25
A measuring device of the class described
comprising a frame having an opening in
one side, folding supporting legs for said
frame, the side bars of the latter being slot-
ted longitudinally at one side of said open- 30
ing, boxes mounted in these slots, a shaft
journaled in said boxes, a contact wheel
niounted on said shaft, a yoke connecting
said boxes, a screw extending from the cen-
ter of said yoke through the contiguous end 35
of said frame, a nut on the screw, outside
such end, a spring coiled on the screw be-
tween the end of the frame and. center of
the oke, a- second contact wheel journaled
in te, frame at the opposite side of the 40
opening therein,"a counting mechanism con-
nected with the last-mentioned wheel.
In testimony whereof I affix my signature.
