ment 25 at one end bearing against the yoke.
The parts 24 and 25 are mounted in ears 26
projecting from the support and a tension
lever 27 pivoted on the rear side of the sup-
5 port has a lug 28 in engagement with the
part 25; while a coiled spring 29 extending
from the lower end of the lever holds the
lug-in engagement with the part 25 whereby
sufficient friction is exerted on the spool to
10 alleviate the play. Between the flanges of
the spool a supporting roller 30 is mounted
on the platform 7 so that the roll of paper
rests directly thereon. The line of contact
between the roller 30 and the roll of paper
15 registers with the horizontal plane of the
points of contact between the pinion 20 and
the face 19. By this arrangement as the di-
ameter of the roll on the spool 16 increases
the spool is displaced upward so that the
20 relative point of engagement between the
pinion 20 and the face 19 is moved outward
from the center and the gear ratio in-
creased in proportion to the increase in the
diameter- of the roll of paper, whereby the
25 strip of paper is caused to travel uniformly
irrespective of the diameter of the winding
roll.
In using the measuring device the hand 2
is always set at the zero mark. When the
30 meter is operated the mechanism associated
with the shaft 3 rotates the latter and causes
the hand to travel clockwise and to succes-
sively pass over the units of measurement
on the dial. During this operation the gear
35 23 is being rotated whereby the spool 16 is
revolved and the strip A traversed. At this
point the operator writes on the strip A,
which is exposed over the table 11, the read-
ing of the meter and any other designation
40 such as the name of the customer or the
character of the sale if desired. I also pro-
vide for mutilating the paper strip at this
point which affords a check on the record
for the reason that the paper must travel the
45 same distance for each unit of measurement
and by measuring the distance between each
successive mutilations or punched holes the
- exact quantity dispensed may be accurately
determined. I arrange this mechanism to
so be operated when the hand 2 is returned to
zero after. each sale or operation of the
meter.
.For carrying out this operation I mount
on the underside of the inclined portion of
55 the support 6 a rock shaft 31 having an off-
set spur or point 32 arranged to swing
through an aperture in the table 11 and
punch a hole in the strip A. The rock shaft
has a crank arm 33 at its lower end which is
60 pivoted to the upper end of a link 34 dis-
posed at an angle between the parts 26 and
passing down through the platform 7. The
link 34 has a hook 35 on its lower end in the
path of an eccentric lug 36 on the shaft 3.
65 A coiled spring 37 attached to the link andone of the ears 26 holds the link upward
and the rock shaft in its normal position
whereby the spur 32 is inactive below the
table. When the hand 2 is swung counter
clockwise to return it to zero the shaft 3 is 70
revolved so that the lug 36 engages the hook
35 and pulls the link 34 downward. This
swings the crank 33 and rocks the shaft 31
whereby the spur 32 is swung through the
aperture of the table and the paper punched. 75
Just- as soon as the meter is again started
the shaft 3 is rotated in the opposite direc-
tion whereby the lug 36 is carried out of the-
path of the hook 35 and the spring 37 given
an opportunity to return the parts to their 80
normal position and swing the spur out of
the paper.
What I claim is,
1. In a recording apparatus, the combi-
nation with a measuring device having an 85
indicator which is arranged to be reset for
each measuring operation, of a support, a
writing table mounted on the support, a
strip of paper carried by the support and
passing over the writing table, a spool 90
mounted to swing on the support and on
which the strip of paper is wound in a roll,
a shaft carried by the support and driven
by the measuring device, a friction pinion
on the shaft engaging the spool, a roller 95
mounted on the support and engaging the
roll formed by the paper wound on the spool
for supporting said spool, a punching de-
vice mounted on the support and having an
element for penetrating the paper, and a 100
device for operating said punching element
in position to be operated by the indicator
of the measuring device when said indicator
is reset.
2. .In a recording device, the combination 105
with a writing table adapted for supporting
a writing strip traveling'in contact there-
with, a substantially vertically swinging
support arranged near the table, a spool car-
ried by the free end of the support and 110
adapted to have the writing strip wound
thereon for providing a roll increasing in
diameter during the operation of the de-
vice, a support held stationary beneath the
spool, a supporting roll carried by the sta- 115
tionary support and engaging the strip roll
of the spool to shift the spool upwardly, a
substantially vertical rotatable shaft dis-
posed near one end of the spool and held
against vertical displacement, a friction 120
gear rigidly secured to the substantially ver-
tical shaft and contacting with the, end of
the spool, and means to rotate the substan-
tially vertical shaft.
3. In a recording device, the combination 125
with a spool for holding a writing strip, of
a swinging support, a second spool carried
by the free end portion of the swinging sup-
port and adapted to have the. writing strip
wound-thereon for providing a roll increas- 1300
