as a mounting means for an apron |49 which is

ls provided with Aastub shaft |5I upon which
la roller |52 is journaled. 'I'his roller is received
in a cam groove |53, formed in a collar |54 which

The upper end of the apron |49 is provided with

hinge connection is formed with teeth |10b which
are engaged by teeth |1ûc formed on a shaft |10d
which is actuated by a manually operated crank
In order that' the ends of .the housing may be
sealed effectively, end seals are provided thereon,
such end seals comprising arcuate plates |84
upon which gear sectors |85 are provided. This
10 structure is shown in Figures 8, 9 and 17. Hous
ing end walls |85 are provided with apertures |81
in which shafts |88 are journaled, the shafts be
ing formed, at their inner ends, with gear teeth
|89 for engaging the respective gear sectors
| 85, the outer ends‘of the shafts |88 being pro
v vided with hand wheels |90. Each hand wheel
is provided with a friction lock comprising Va
spring pressed detent |90a riding in a groove
|88a formed in the shaft |88. The arcuate seal
ing plate |84 is mounted upon an arcuate bracket
slot 20.1, formed in the dial 20|. In this fashion,
the arm 206 and slot 201 serve as a device for v
limiting the pressure to which the doctoris
>subjected by means of the manually operated
knob |83.
By means of the pressure indicator construc
tion above described, a permanent initial, setting
for a given size printing cylinderis provided,
such initial setting serving to enable the posi
tion of the wiping mechanism to be adjusted
properly. In operation, a doctor knife |59 hav l0.
ing a new wiping edge is mounted in the machine
and the indicator 200 is moved until the first or
zero number appears through the aperture 203
on the cover |10.
The wall plate |4| is next ad
justed by means of the wrench end "|31 until a
clean wipe is obtained on the printing surface
|96. During operation and as the edge of the
doctor wears, the operator turns the knob |83 to
compensate for such wear until the indicator 20
|9|, the outer periphery of which conforms to reaches the limit of its reading and until the arm
205 reaches the limit of slot 201. At this stage,
the curvature of the printing cylinder, the brack
et being formed with a flanged portion |92 and a the operator cannot apply more pressure to the
rib |93 which liesbetween the sealing strip 18 vdoctor because of the lock afforded by the arm
and the doctor |59. The plate |84 is formed and slot of the indicator. At this point the in
dicator shows the operator that the wiping edge
with ja groove |94. within which the ribk |93 is re
ceived, and is further formed with a parallel of the doctor has been worn to its tolerable max
flanged portionv |95 between which and the plate- imum and the reconditioning of the edge is now

the plate |84 is mounted for sliding» movement with a reconditioned or new one, a clean wipe 30
about the axis of a printing cylinder |96 which ' will be obtained when the indicator is brought
is illustrated in Figure 9, 'as well as in Figures again to zero position, without having to read
_ 3, 4, 10, 11 and 14. A ñexiblestrip |84a. is rivet- » just the wiping mechanism. In this fashion the
initial setting may be considered as a permanent
one as long as the diameter of the printing cyl
of plate |84 and projects circumferentially there- ' inder remains the same. Furthermore, by means
of at |84b and abuts against the adjacent edge of the above indicator, the cover |10l may be
ed to the under side of each plate |84. ` This strip
(Figure 17) lies under the overhanging portion
|92a of the flanged portion |92 of bracket |9|.
In this fashion the top surface of the flexible
40 strip | 84a lies in the plane of the top surface |9217
of the bracket |9|. The strip |84a is coexten
sive with the plate |84 at the doctor end thereof
and with the flanged portion |92 of bracket |9|
on the inking side of the housing.
The portion |84b of the flexible strip and the
adjacent portion of the ñange | 92 are received
under the sealing strip 14 and an effective seal*
between the strip, housing end wall and cylinder ¿
is thus preserved in view of the fact that the strip
14 does not move during operation of the press.
Inasmucli as the doctor |59 reciprocates, the
sealing plate |84 cannot lie beneath the doctor
because of the objectionable wearY resulting there
from. In accordance with the present invention,
the hand wheel |90 affords a means by which the
plate |84 may be advanced against the doctor |59
into abutting sealing engagement therewith (see
Ythe same number which existed at the time the .
cover was moved from its normal operating po
sition. The zero position of the indicator may
be changed by movement of the dial upon the
shaft >|16 and the limit position afforded by the 45
slot 201 may be changed by changing the position
of the bracket carrying the arm 206.
It will thus be seen that the construction de
scribed herein provides an improved fountain
wherein the operating parts are enclosed and 50
maintained away from the ink and ink vapors

such as to facilitate the cleaning and maintenance
thereof, particularly in` view of the minimum

cylinder |96, and doctor |59.
Moreover, the construction is such that no ink
which accidentally escapes from the housing can
reach the moving and adjusting parts of the con
trol mechanism. This is illustrated particularly
As illustrated in Figures 7 and 16, the shaft
|16 is provided with avclamp 200 having an arcu-ate indicator dial 20| upon which suitable indicia
is inscribed. This dial is positioned within a
curved portion 202 of the cover |10. . An aperture
in Figure 10 wherein the reciprocating mechanism
for the doctor is maintained away from the arcu-"
203 is provided in such curved portion in order

that the indicia on the dial 20| may be viewed
In this fashion, if the sealing blade |60 fails to
effectively seal the doctor along the entire length
thereof, and ink escapes at such faulty seal, it will
moved and returned again into its normal op
erating position without affecting the pressure
adjustment of the pressure blade |69. This is
done simply by restoring the indicator dial to 40
A sleeve 204 is provided on the shaft |16, and
