VThe brackets I 46 serve as a mounting means for an apron |49 which is 60 secured‘thereto by means of bolts |50. The apron 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 is secured tothe shaft I4|).` Inasmuch as the 65 bracket |46 is slidably mounted upon the rod |45 and shaft |40, rotation of the shaft |40 will cause the rapron |49 and-brackets I 46 vto be recipro cated through the groove and roller connection downwardly from the cover and receives a knurled » knob |83 in order that the vstub shaft may be rotated to rotate the shaft |16. In this fashion when the cover has been swung into such po sition that the contact member |14 engages Ythe apron |49', the knurled knob |83 `is turned until the eccéntrics |15 force the cover effectively into the closed position shown in Figure 10, at which time the >pressure blade |69'engages the doctorK |59 to force thesame into the wiping position 65 illustrated, at the same time causing >the seali ing blade |60 to be deflected, asillustrated in Figures 10, v11'and 14. In >Figure 10 the dot and dash lines illustrate the position of the'cover when it has been swung 70. an elongated groove |55 within which a doctor back away Vfrom the apron to permit access to holder |56 may be secured by means of clamps the latter. It will be seen, from Figure?12, that |51 and bolts |58 (Figure 14). 'I'he doctor holder the hinge connection |13 includes the Ylock pin is provided with a flexible doctor |59 which thus _ |10a which also serves as the hinge element by 75 is .caused to reciprocate in accordance with the means of which the cover |10 is hingedly Acorn above described. 7.0 v . - The upper end of the apron |49 is provided with 5 2,115,376 nected to the link |1|. Lock pin |10a of each 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 arm |106. `. ' ` 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 15 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 |84, the flange |92 is received. In this fashion, necessary. Having replaced the worn doctor 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 35 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. l 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 >within the housing, the construction also being such as to facilitate the cleaning and maintenance thereof, particularly in` view of the minimum number of projections from the fountain hous 55 ing. All locking members are convenient and Figures 8 and 17) when the latter has been moved to its wiping position, thus preserving an accessible and the control mechanism is -such as to insure a proper sequence of operations to pre effective seal between the housing end wall |86, vent damage to the mechanism. 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. .

This is done simply by restoring the indicator dial to 40 A sleeve 204 is provided on the shaft |16, and secured to the bracket |11 which is fastened to flow down the upper surface of the arcuate plate cover |10, the shaft |16 being journaled in sleeve |4| and not contact the reciprocating and con 204.
