horizontal slideways 39, the latter provided at the
upper side of the framesv i2. Stops 40 near the
opposite ends of the sideways limit the extent of
reciprocating movement of the slide 38.
For the purpose of forcing the coloring ma
terial through the screen 34‘, there is provided
a wiper 4| or squeegee depending from an arm
42, said arm being adjustably mounted upon a
horizontal rod 43. This rod 43 is secured at its
10 inner end to a rockable bracket 44 which is
pivoted through a hinge pin 45 to the frames I2.
Rocking of the bracket 44 for the purpose of
reversing the inclined position of the squeegee
4| is obtained by mounting upon the slide 38 a
pair of cams 46, said cams bemg spaced apart
and positioned for engagement with the hori
zontal rod 43 at the opposite ends- of the path
of reciprocation of the slide.’ These cams 46, as
is evident in view of their particular contour,
serve to lift the squeegee 4i away from the screen
a short distance during‘ the. reversing of the
will be apparent presently, by means including
a ratchet 69 pinned to said shaft 6'! and pawl ‘ll
engageable with the ratchet and carried by a
lever ‘II. This lever ‘H is connected through a
rod 12 to the treadle 3| referred to heretofore.
Therotor 55 is provided with four ports ‘II
which are equally spaced about the rotor in
proximity to its periphery and extend parallel
with the axis of the latter. These ports are
adapted to be brought into register one at a time
with, exhaust ports 14 leading to exhaust pipes
15. These exhaust ports are spaced apart 135°
and are disposed directly opposite the point of
connection between the housing 56 and the pipes
63. Thus, it will be apparent that register of one 15
of the ports 13 with either of the exhaust ports
14 will result in an immediate drop in the pres
sure at that end of the cylinder directly com
municating with the particular exhaust port 14.
Consequently, the piston 62 will move to that
end of the cylinder from which the air is being
exhausted. Because of the difference in capacity

terial may be uniformlgdistributed over the of themain supply pipe 55 and branch pipes ll,
screen. For the purposeof assisting the cams opening of either branch pipe 55 to the atmos
44 in reversing‘the squeegee, a stationary cam , phere by way of one of the exhaust ports 14 re
41 is mounted upon the frames l2, said cam being duces the pressure'in one end of the cylinder
formed with two straight inclined surfaces which below that in the other end. By reference to
engage \the horizontal. rod 43 carrying the
squeegee. The rod moves from one inclined ‘sur
35
face to thelother at each end of the path of
reciprocation of the slide 30 and thereby insures
reversal of the angular position of the squeegee.
Reciprocation of the screenframe and oscil
lation of the bottle B about its longitudinal axis
are synchronized by providing driving connection
between the slide all and the pulley 25 referred
to heretofore as forming a part of the chuck unit.
To this end, a cord 45 is wrapped about the pulley
25 and has‘ its opposite ends suitably secured
‘to brackets 49 or arms‘ which are carried by
, the-slide 35. Thus,it is apparent that recipro
‘ cation of the slide 38 operates through the cord
48 to oscillate the pulley 25.. Corresponding
'- oscillatory movement is thereby imparted to the
‘chuck I3 and bottle B supported therein.
Reciprocation ‘of the slide it isrobtained by
means of a:?vui,d operated piston motor 50 which
is mounted upon'the table Ill 'and‘secured thereto
Fig. 8 this operation is readily understood.
In operation, a bottle is positioned in the
chuck i3 as indicated particularly in Figs. 3 and
4. Immediately thereafter, the treadle 3! is de
pressed with the result‘that suction or vacuum
is applied to the chuck and thereby securely holds
the bottle therein. Simultaneously with this op
eration, the rotor 55 is moved 45° about its axis
bringing one of the ports 13 into register with
one of the exhaust ports 14. As stated hereto
fore, this results in movement ofthe piston 52
to one end of the cylinder 54 whereby movement
is, imparted to the screen 34'.
Owing, to the 40
driving connection between screen frame and the
pulley 25 through said cord, 45, the chuck is
oscillated in synchronism with the reciprocating
movement of the screen frame. _The squeegee or
wiper functions as is customary to force the col
