I08 fromthe font I05. When the level of the
water in the tube I08 drops, due to the dis 45
tribution of the water, air enters through the
vent I09 and allows the out?ow of water from
the font. It is'to be understood that the ?ap
of each envelope as it is advanced by the pad
91 will be partly raised. l-Ience, as each en 50
velope is advanced the flap will pass in contact
with the upper surface of the tube I08 and the
adhesive substance on the ?ap will take up or
be smeared with water passing out of the holes

show that the roller | 2| is mounted directly
therebeneath. The shafts of the rollers I20 and
10 |2| are supported by suitable bearings carried
by spaced standards I23, as shown. The roller

and 5, it will be apparent that there are shown
spaced standards 20 and 2|. These standards
will be arranged adjacent the discharge end of
an envelope magazine of the type referred to
hereinabove. A shaft 22 is supported in hori
zontal position by lugs 23 on the standards 20
and 2|, respectively. Arms 24 have their lower
ends connected with the shaft 22. The arms
24 are thus mounted for swinging or pivotal
movement, and embody bearings which receive
the opposite ends of the shafts respectively of
the pressure sealing rollers 25 and 26. The roll
ers 25 and 26 are similar to the rollers I20 and
HI hereinbefore referred to. A transmission
shaft 2‘Iv is mounted for rotation in suitable
bearings 28 secured to the standards 20 and 2|.
A latch 29 carried by one of the arms 24 is
engageable with one end of the shaft 21 in order
to latch the sealing rollers 25 and 26 in position.
The shaft 21 has a bevel gear 30 fast thereon
which meshes with a drive gear 3| of the sheet
folding mechanism. The shaft 21 also has a
gear 32 fast thereon which meshes with a gear
33 on one end of the shaft of the roller 26 in
order to cause the continuous rotation of the
roller 26. The gear 33 meshes with a similar gear
on the shaft of the upper roller 25 in order to
cause the latter to rotate in a direction opposite
to the rotation of the roller 26.
The moistening device is employed in con
junction with the sealing rollers 25 and 26 and
also in conjunction with a tape or strip-feeding
70 means to be hereinafter described. The moist
the cup 4|, and its upper extremity is secured in
any suitable manner to a head 45 adapted to 25
receive an adjusting screw 46 having a valve
member 41 which projects into the end portion
44 and snugly ?ts in the same. The end portion
44 has holes 48 diametrically opposite each other
which permit water to ?ow from the cup 4| into 30
the tube 43. The end portion 44 also has a hole
49 therein above one of the holes 48, and an air
vent 50 secured in the cup 4| adjacent the end
portion 44 has its lower end in communication
with the hole 49 and its upper end in communi
the screw 46 in order to completely shut off both
air and water to the tube 43, or to shut off the
air only, or to admit both air and water to the
tube 43. The tube 43 has a narrow longitudinal
waterdistributing slit 5| therein approximating
the slit 38 in the tube 31, as shown in Fig. 5.
The tube 43 has a branch distributing tube 52
connected therewith so as to be rigid with the
portion 44. The tube 52 is bent in order that
the major portion thereof will be spaced from
and disposed substantially parallel to the dis
tributlng portion of the tube 43. The branch
tube 52 has a narrow longitudinal water dis
tributing slit 53, the said slit opening laterally
and downwardly. The branch tube being in
communication with the tube 43 will receive 55
water and air therefrom. ' In order to effectually
control the ?ow of water from the font 34 to
the tube 31, there is provided an air vent tube 54
which is substantially L-shaped. A portion of
the tube extends through the socket 36 and rises
into the font 34 through the outlet. The other
end 55 of the tube 54 is the air inlet end. Air is
admitted periodically to the tube 54 in a manner
to be described. In order to catch any over?ow
of water when the font ?lled with water is in 05
verted to be engaged in the socket 36, there is
provided a drain box 56 secured in ?xed position
in any suitable manner to the standards 20 and
2|. A drain pipe 51 connected with the box 56
carries off the over?ow of water from the box 70
ener includes a water font or bottle 34 having a

31, there is provided means as follows: A block
58 is secured in the box 56'an'd' is bored- and
threaded to receive the threaded inlet "end 5510f
the tube 51$. An ‘air passage‘59 in‘the block 58
communicates ‘at one end with the bore and at
its other end opensto ‘a guideway 6| in which a
slide 82 is vertically movable up and down.‘ The
slide 62 has an air port 63 which maybe brought
into and out of registry with the passage‘59 upon
up-and-down movement of ‘the slide 62. The
slide 82 has a notch“ 64 therein. ‘A crankshaft
85 is mounted for rocking‘movement'in‘bearings
88 and 61, respectively, on the standard 2| and
a ‘standard 68. The shaft 65 has a crank 69.
A small bracket ‘16 is pivotally connected with
the roller 86 below the same. The roller 86 c0
operates with the roller 26 to move the advance 15

in the present instance as follows. Cooperative 20
slide 52. An adjustable cam ‘15 is mounted ‘on
a shaft on which'the gear 3! is mounted. The
cam 15 cooperates with a spool or the ‘like on vvthe
end of a crank 16 of the shaft 65. A contractile
spring Tl has one end thereof connected with the
25 crank 76 and its opposite end connected with the
standard 68. The spring yieldingly retains the
crank ‘F6 in cooperative engagement with the
cam l5 and causes return movement of the crank
shaft 65. In each revolution of the cam 15, the
30 slide 62 will be caused to move down and then
up, through the intervention of the shaft 55,
bracket 18, and rod 12. This action takes place
to correspond with the advance of the envelopes
to be sealed in succession.
In order to cause the movement of the tube 43
35
into and out of water distributing position, in
arcuate guides 90 and 9|, respectively, are se
cured to the box 56 adjacent'the roller 26 in
?xed relation thereto. The guide 9l_ has a suit
able cutter92 on its upper end, the. same con
sisting of a series of ?ne teeth bent laterally in 25
ward or toward the guide 90, as shown most
clearly in Fig. 8. The tape passes between. the
guides 90 and 9| up to the roller 86; In each
down movement of the slide 62, the de?ector 89
pushes the tape into cutting relation to the cut 30
ter 92. At this time the tape is being advanced
by the cooperation of the rollers 86 and 26, while
the roller 83 is down away from the roller 26
out of cooperative engagement with respect
thereto due to the down swing of the crank 69. 35
In other words, the tape will be pressed ?at
response to the up-and-down movement of the
wise against the cutting teeth.
slide 62, the slitted end of the tube 43 is secured
to the upper end of the slide, as at T8, or in any
against the cutting teeth while the tape is being
pulled upwardly causes the teeth to penetrate
suitable manner. The slit 5| in the tube 43 ap
plies a ?lm of water on the front face of each
and cut the tape by reason of the cooperative 40
action of de?ector 89 and rollers 86 and 26. The
tape will be cut crosswise to sever a piece of
predetermined length, the gum of which will be
moistened by the tube 52 and will be drawn
along by the rollers 25 and 26 and be pressed
into contact with the front face of the envelope
envelope as it is fed thereto due to the fact that
the distributing end of the tube 53 will be ?exed
upwardly and retained momentarily as each en
velope is being advanced. It is understood that
each envelope will be advanced in part by a
feeding mechanism and by the rollers 25 and 26.
The envelope is designated E (see Fig. 8).
The branch tube 52, by virtue of its slit 53, dis
tributes or spreads a ?lm of water on the gummed
surface of an endless tape or strip 19, which
is advanced and cut in separate pieces of pre
determined length by means to be hereinafter
described. This tape or strip may contain print
ed addresses or other matter to be applied to en
velopes and folders; or the tape or strip may
consist of postage stamps with the usual trans
verse lines of perforations, the stamps to be af
‘ ?xed on the face of envelopes, folders, and other
00
regular intervals is _moved into and out of co
operative relation with the roller 26 in response
to the rocking movement of thecrank shaft 65.
A bracket 84 is ?xed to the drain box 56 adjacent
the slide 62 and in line with the rollers 82 and
83. The bracket 84 provides end bearings 85,
which support a roller 86 cooperating with the
roller 26. A rocker frame 81 is arranged between
the end bearings 85 and is supported for lock
ing movement by the ends of the shaft of the 10
roller 86. The frame 81 has cars 88 through
which the lateral end 14 of the rod 12 extends.
The frame 81 has a deflector 89 which parallels
mail matter. A roll of tape may be supported by
any suitable means, indicated generally at 86,
and secured to the base of the standards 20 and
‘fl below the sealing rollers 25 and 26. The roll
of tape is supported so as to be unwound freely.
The feeding of the tape is accomplished by
the means and in the manner presently to be
described. A frame 8! is ?xedly secured to the
crank 69. The frame 8| supports a guide roller
82 and a larger guide roller 83 is mounted on
the arbor of the crank 69 between the ends of the
frame. The roller 83 cooperates with the roller
25. The tape 19 passes around the rollers 82
and 83, as shown in Fig. 8, and is positively ad
vanced periodically ‘by the cooperation of the
roller 83 with the roller 26.
The roller 83 at
Thetape held
and thus be secured or ai‘?xed thereto as the en
velope is being sealed. It is to be understood that
the cutting of the tape into separate pieces will
be in timed accord with the feeding and mois
tening of each envelope and the wetting on the
front face thereof by the tube 43.
In operation, the gum or adhesive on the flap
of each envelope will pull a water ?lm from the
slit 38, which will start from a point near the
vent 48, bending upwardly to cover this vent just
beyond reach of the edge of the envelope ?ap.
Normally, the ?lm will remain that Way with
enough air being admitted to the tube 54 by vir
tue of the operation of the slide 62, which air 60
is introduced above the water in the font 34.
Should the demand for water ?lm be increased
by the character of the gum or adhesive surface,
width thereof, etc., then the ?lm covering the
vent 48 will be drawn down and additional air 65
will enter the tube 31 to insureproper flow and
distribution of the water. The additional holes
39, due to their lower level, allow the ?lm of
water to protrude, catch on the envelope ?ap,
and so on up to break into the ?lm in the slit 70
38, as indicated in Fig. 11.
The tape reaching the tube 52 is stiff enough
to move away from the roller 26 and, hence, push
es against the water ?lm of the slit 53. When
long pieces of tape are to be applied, there may be 75
4
2,136,468
a tendency for the tape to move away from the
tube 52; also, the lines of perforations between
stamps, in the event that the tape is of this char
acter, will cause the tape to lack stiffness. There
fore, a de?ector and guide 93 carried by the
bracket 84 is employed to insure the proper mois
tening of the gum or adhesive substance. Where
postage stamps are applied, a rupture at the
perforations will be caused by the cutter teeth,
10 which are the same number. to the inch as the
stamp perforations.
By adjusting the cam 15,
the cutting of the tape is controlled so as to give
separate pieces of the desired length, or rupture
at the lines of perforations in the tape.
It is to be understood that the device may be
15
used for applying adhesive substance directly to
the materials instead of applying water to ad
hesive or gum carried by the material. It is not .
necessary to moisten both the gummed surface
of the tape and the face of each envelope in the
same operation, and one feature may be used
without the other. Furthermore, it is to be un
derstood that details of construction may be modi
?ed and the parts rearranged to carry out the,
results looked for without departing from the
invention as expressed in the appended claims.
I claim:
1. A device for applying suitable liquid to suit
able material fed in a de?nite path, comprising
a liquid font having a ?exible liquid distributing
tube projecting therefrom, means to ?ex said
tube to apply liquid to said material at regular
