LESTER E. MARTIN BUCKHORN, CHEA THA M 8: BLORE A T TORNE Y5 United States Patent 015 3,173,363 INK AGITATOR Lester E. Martin, Portland, Greg, assignor to Graphic Industries Equipment, Inc., Portland, Oreg., a corporation of Oregon Filed Feb. 26, 1962, Ser. No. 175,587 6 Claims. (Cl. 101-364) This invention relates to ink agitators for printing machines and particularly for an ink agitator for a relatively small machine such as a check printing machine.
It is a main object of the invention to provide a selfpowered ink agitator attachment for a small printing machine and particularly one than can be attached without modification of the machine and can be readily detached in a matter of seconds.
Various other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings wherein:
FIG. 1 is a top left perspective view of a printing machine having an ink agitator attachment of the invention;
FIG. 2 is a vertical section taken along line 2-2 of FIG. 1;
FIG. 3 is a vertical section taken along line 33 of FIG. 1;
FIG. 4 is a vertical section taken along line 44 of FIG. 1;
FIG. 5 is a generally horizontal section taken along line 5-5 of FIG. 4;
FIG. 6 is a perspective view of my attachment taken from'the underside thereof;
FIG. '7 is a sectional view taken along line 7-7 of FIG. 6, showing the blade in phantom lines;
FIG. 8 is a perspective view of the ink agitator member looking generally at the front thereof; and
FIG. 9 is a rear elevational view of such member.
Referring to FIG. 1, the printing machine 11 has a plurality of inking rollers some of which are shown and are identified as 13a, 13b, 13c, 13d, and 132 for picking up ink from a pan 15 and transferring a film of ink to a cylinder 17. These rollers and the cylinders are driven by means not shown and concealed by housings 19 and 21.
Referring to FIG. 2, the pan 15 is shown resting on a rod 33 supported by the frame of the machine. Each end wall 35 of the pan has a keyhole slot or recess 36 to embrace a flat portion 37 of a stationary tubular bearing 38. The bearings 38 support the ends of a shaft 39 of the roller 13a. When the pan is swung clockwise suificiently to align the slots 36 with the fiat portions 37, the pan is pulled forwardly to remove it. It is reinserted by following the reverse procedure.
The pan has a film forming blade 41 mounted by screws 43 on the front lip of the pan 15 in a position to dispose its lower edge close to the roller 13a. A series of adjustment screws 45 determine the ultimate position of the lower edge of the blade 41 with relation to the roller 13a.
The self-powered ink agitator of the invention is designed to be detachably mounted on the printing machine in a manner permitting its ready detachment. The agitator includes a pair of spaced parallel vertically elongate side members 51.and 53 (FIG. 1) of generally similar but specifically diiferent shape (FIG. 4). A. tie rod 55 (FIGS. 4 and 5 extends through holes in the upper ends of the side members and is secured in place by setscrews 57.
I The'lower portions of the side members 51 and 53 are similarly formed and each is formed with a downwardly facing semicircular recess 61 (FIG. 3) of a size to embrace the bearings 38 of the roller shaft 39. Each side member is also formed at a lower level with a smaller downwardly facing recess 63 of a size to embrace the 33733623 llga tented Mar. 16, 1965 pan-supporting rod 33. The directions in which the recesses 61 and 63 open are parallel and thus the side members may be removed by an upward force and replaced by merely fitting the recessed portions onto the bearings 38 and the rod 33.
The agitator includes an agitator member indicated by the general reference numeral 71 which is detachably mounted by a pair of thumb screws 73 (FIGS. 1 and 2) on a nut 75. The nut fits on a cross threaded reversing screw 77 fitting at one end (FIG. 5) in a hole 79 formed in the side member 53 and formed at its opposite end with a bore receiving the output shaft 81 of an electrical motor 83. A coupling sleeve 85 has a setscrew 87 passing through a hole in the wall of the screw 77 and engaging a flat on the shaft 81. The side member 51 has a suitable opening 89 to accommodate the sleeve 85.
The motor 83 has three threaded mounting pads 91 (FIG. 5) secured to the outer face of the side member 51 by screws 93 (compare FIGS. 1 and 5).
When the motor 83 is energized through a cord 95 (FIG. 6) the screw 77 is rotated to drive the nut 75 longitudinally of the screw, the nut being prevented from rotation by a guide rod 55 (FIG. 3) which passes through a slot 99 in an arm 101 extending from the body of the nut 75.
The agitator member (FIGS. 8 and 9) comprises a thin metal plate of generally inverted U-shape and including a pair of downwardly tapering fingers 105 joined by a bridging portion 107. The agitator member is bent slightly below the bridging portion so that the bodies of the fingers are at a slight angle to the bridging portion.
The lower end portions 109 of the fingers are bent almost at right angles to the remainders of the fingers. The various angles of the agitator member are chosen so that the lower faces of the lower portions 109 lie flush against the blade 41 (FIG. 2) and so that the tips of the portions 109 are disposed close to but in spaced relation with respect to the roller 13a.
The fingers are spaced apart a distance less than half the length of the pan 15 so that paths of travel of the fingers overlap to give a wiping action to the entire length of the pan. The length of the threads of the screw 77 is such as to drive the agitator member a distance just slightly less than the length of the pan 15 minus the distance between the outside edges of the portions 109.
Since the side members 51 and 53 merely rest on the bearings 38, they can slide along such bearings. Thus, there is no need to accurately locate the agitator attachment laterally relative to the pan 15, since if it is not correctly located, the agitator member 71 will be brought into engagement with an end of the pan to push the attachment into a centered position relative to the pan.
Referring to FIGS. 1 and 9, the agitator member 71 is formed with two recesses or edge slots to receive the shanks of the thumb screws 73. This permits removal of the agitator member 71 from the nut 75 without removing the screws 73.
The supply of ink I is shown in FIG. 2 with the fingers portions 109 projecting into such supply to assume proper agitation and distribution of the ink along the blade 41.
While the agitator of the invention is shown attached to a particular type of printing machine, the agitator can be detachably mounted on various other types of machines.
It is apparent, for instance, that the distance between the side members 51 and 53 can be readily varied by loosening the setscrew 57 for side member 53, moving the side member relative to the screw 77 and rod 55 and retightening the setscrew. This could be done to adapt the agitator to a difierently dimensioned machine.
The agitator of the present invention is particularly useful in agitating magnetic ink to keep the iron oxide 3,1 3 from settling out, but the agitator is also very useful in agitating other inks, to avoid waste and to insure a uniform film of ink on the transfer rolls.
Having described the invention in what is considered to be the preferred embodiment thereof, it is desired that it be understood that the invention is not to be limited other than by the provisions of the following claims.
