invention relate l teint; fountains for use with printing., machines andI more particularly.
to a retractable mounting for a fountain. blade that. is located, in` the fountain and which cooperates with a fountain roller.
The fountain. roller ofi a` printnxg` machine is commonly mounted to rotate in an ink fountain from which it picks up a quantity of" ink. A.
flexible metallic fountain blade engages the surface of the fountain roller' and. `removes excess ink therefrom. Occasionally.- .it is desirable tot clean:` the nllrl fountain withl fountain blade androller and in order to facilitate this operatienel the; invention has for enea-ofits objects;the,y
prouisionof-an improved mechanism for mount-V ngzafountain blade. n .A
Another object of the invention is the provision of a new and improved fountain blade mechanism wherein the fountain blade can be moved from engagement with the fountain roller for cleaning and then reset with ease and without disturbing its adjustment.
Other objects of the invention will appear in the following description and claims.
A preferred embodiment of the invention is shownv in the accompanying drawings wherein:
Figure 1 is a view partly broken away showing an ink fountain with its fountain roller and cooperating fountain blade mounted in accordance with the invention, the parts being shown as seen in the direction of arrow I in Figure 2;
Figure 2 is a sectional view on the line 2-2 of Figure 1 and as seen in the direction of the arrows; Y'
Figure 3 is a fragmentary view of a portion of the mechanism shown in Figure 2 as seen in the directionof the arrow 3; and
Figure 4 is a fragmentary sectional view on the line 4--4 ofFigure 1 as seen in the direction of the arrows.
A conventional fountain roller IU is rotatably supported in an ink fountain II by a pair of roller bearings I2 that are held in bearing housings |3 formed in side members I4 of the fountain, by screws I5 and plates I1. The roller I0 is rotated in the direction shown in Figure 2 by means not shown, and a ductor roller I8 is rotatably mounted in a pair of oscillatable arms I9 and is moved alternately into engagement with the roller It and an ink distributing roller (not shown) The ink fountain II includes side frame members I4, and a fountain frame 2|, that is secured in the printing machine by bolts 22, and has an upper machined surface 23V on which is slidably *Y mound-.edL a lower clampingmember 2:4. '13nelower clam-ping member is sl-ida-bly held te, the frame `2.51 by a plurality'- of bolts. 25.` Each` bolt ispronided with a washer 'nl and extends through .a `LI.-shaped slotY Z,v inv the. frame 2h. and: is. screwed intoathreaded hole 2-9= in. the clamping member 2.4. Anupper clamping member V3u secured to the lower clamping member` 24 by bolts 32 and the two clamping; members; thus lforma. blade holder which rmly holds a foun- `tainblade33` in properposition. A longitudinally extending` recess. 34v having an inclined surface 35. is provided. in theupper surface 23 of the fountain. frame, and a. 11u31 formador-i the-edge? of, thelower clam-ping member 24 eooperateswith;
' 'theinclined surface 35 to provide.- a fountainA blade lifting device. bar- 33, securedv to. the` forward edge of the frame 2|, is held in place by a plurality of bolts 39|. A plurality of threaded holes 4| extend through this bar and each hole carries a threaded thumb screw 42 having a head 43, whereby the edge of the fountain blade 33 may be conveniently adjusted with relation to the fountain roller |Il.
A means for slidably moving the clamping members 24 and 3| together with the doctor blade 33, toward and away from the fountain roller Ill, includes a pair of levers 45, pivotally supported on pins 44, held in bearing blocks 46, that are secured to the frame 2| by screws 5I). The upper end of each lever 45 enters a hole 41 provided in the lower clamping member 24. A slot 48 is provided intermediate of the ends of each lever 45. Each end of a shaft 43 that is rotatably supported in the bearing blocks 45 carries an eccentric pin 53 which passes through the slotted holes 48 in the levers 45, and the shaft is provided with a diametrical hole 54 in which an operating rod 55 may be inserted.
Adjustable means for limiting the forward movement of the clamping members 24 and 3| and thus the doctor blade 33 is provided and includes a stop 5'! (Figure 4) secured to the lower clamp member 24. This stop cooperates with a cap screw 58 carried by the frame 2| and has a lock nut 59.
In operation, when it is found desirable to clean the ink fountain |I, the bolts 25 are loosened, the rod 56 is inserted into the hole 54 and the shaft 49 is turned counter-clockwise, as seen in Figure 2, approximately degrees. This causes the eccentric pins 53 to swing the levers 44 and 45 and thereby move the clamping members 24 and 3| to withdraw the fountain blade 33 from engagement with the fountain roller I0. As the lower clamp member moves backward, the lip 31 moves up the inclined surface 36 of the recess 34 and onto the upper machined surface 23 of the frame 2l, thus raising the fountain blade from engagement with the adjusting screws 42. With the fountain blade so withdrawn from the fountain roller, the ink fountainand roller may very easily be cleaned. After the cleaning. the rod 49 is rotated in the reverse direction until the stop 51 engages the screw 58, thus returning the fountain blade to its original position, after which the bolts 26 are tightened. Since the lip 31 rides on the machined surface 23, the forward edge of the blade is held high enough to clear adjusting screws 42, during its return movement. The fountain blade may thus be moved away from its normal position and later returned to the same position without disturbing its adjustment with respect to the fountain roller.
It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being made to the claims rather than to the foregoing description for an indication of the scope of the invention.
What I claim is:
1. In a printing ink fountain having a frame supporting a fountain blade with an edge adjacent a fountain roller and adjusting means associated with the frame for close adjustment of the spacing between the edge of the blade and the periphery of the roller; the combination therewith of a blade holder fitted to a seat on the frame and arranged to hold the blade, means to move the holder and the blade forward on the frame into operating position relative to the roller and backward away from the roller, a lip on the holder, and a lip engaging surface on the frame arranged to engage the lip as the blade is moved backward.
2. In a printing ink fountain having a frame supporting a fountain blade with an edge adjacent a fountain roller and adjusting means associated with the frame for close adjustment of the spacing between the edge of the blade and the periphery of the roller; the combination therewith of a blade holder having a surface fittedto a corresponding surface on the frame, one said surface having a longitudinal recess and the other surface having a lip normally extending into the recess, and means to move the blade holder rearward to withdraw a blade carried thereby from its normal operating position, the saidlip being arranged to move out of the recess and raise the blade holder as the blade is moved rearward and thereby lift the blade from the adjusting means.
