Serial No. 350,743, for Tape serving machines,

This invention relates to machines for the
moistening unit tank and the liquid level is
determined by the position of the open end of
the fountain. When the water goes down in the
tank to below this level the vacuum in the fOllHtain is broken and more water is delivered from
the fountain until the proper level is achieved

moistening of the tape by adjustment of the liq

larly applied to tape delivering machines of the
type which moisten the tape by means of brushes
with which the tape is brought in contact, it
relates to improved means for maintaining a
constant amount of moisture at the portion of
the brushes which contact the tape.

. Considerable disadvantage, however, has arisen
from the use of this type of moisture fountain
in that in re?lling the fountain and replacing
the same, it is always diilicult and usually im
possible to avoid spilling some of the liquid as
the bottle is turned over to place it in position
in the tank. This results in wetting some of

It has been suggested in the prior art to place

Even a careful operator can scarcely avoid spill

Another disadvantage of the present type of
fountain arises from the fact that the fountain
is located right at the point where the tape
is delivered and hence is usually in the operator’s
way, and when the machine is being operated at
high speed, is liable to be knocked off, or broken,
thus flooding the machine and rendering it in
operative. Even if the contents of the. fountain
are not spilled, the position of the fountain very
often interferes with the ‘manipulation of the
brush extending over the top of the tank and to
cause the tape to move over the top of the brush.
The liquid in the tank, which is customarily
water, rises through the brushes by capillary '
attraction. In machines in which the tape is
delivered by grasping‘ the end of the tape and
manually pulling it over the top of the brush,
such moistening units are usually satisfactory,
since the maximum speed at which the tape can
be drawn over the brush is not so fast that the
