ADJUSTABLE ROLLER BEARING.
Application filed May 2,
This invention reiates to inking mechanism for printing presses and the like, and particularly to means whereby the spindle of the ink roller may be adjusted so as to work at the right distance relative to the coacting plate cylinder and also whereby it may be maintained in the adjusted operative position.
On account of the fact that where the plate cylinder of a press is made in sections which are spaced in a longitudinal direction from each other, the weight of the ink roller is apt to press the thin printing plate downwardly a sufficient distance to enter one of said spaces when opposite the ink roll consequently carrying the latter along with it, in which case the continued rapid rotation of the plate cylinder is apt to cause the inkroll to jump and be thrown out of the said space or recess and away from th printingplate which results in the uneven printing of the sheet ofpaper operated upon.
In order to obviate this difficulty I have devised a roller bearing to support the spindle of the ink roll which roller bearing may rest on the bearer of the plate cylinder and be adjusted so that there shall be a light face contact between the ink roll and printing plate carried by the plate cylinder, and also whereby the invention may be adapted to be interchangeably used in printing presseswhere the said parts are of somewhat different sizes.
Another object of the invention is to pro vide means whereby the rollers of my bearing as well as the spindle of the ink roll may be kept properly lubricated at all times.
Another object of the invention is to provide adjusting devices of such a character that the plane of the centres of the rollers and the axis of the spindle of the ink roll may be caused at will to lie at different distances apart by a simple manipulation of the spindles of the rollers Another object of the invention is to pro vide a bearing forthe ink roll which will work with very little appreciable friction. A still further object of the invention is to provide a device of the class described which shall be simple in construction, inexpensive to manufacture and efficient in op eration.
With the above objects of the invention, and ether objects and pur oseswh eh will tales, in rise, the i. ration 1924. serial No. 710,515. 7
consists in the construction, arrangement, pombination and operation of parts hereinbelow set forth. 7
In the drawings, illustrative of embodiments of the invention, which accompany and form a part of this specification- Figure 1 represents a side view of an article constructed according to the invention; Figure 2 is a front elevation, partly in section, of the same; Figure 3 is a side elevation, partly in section, of another embodiment of the invention; Figure 4 is a front elevation, partly in section, of the latter; and Figure 5 is a partial front diagrammatic view of a press in which my invention is used. i In one embodiment of the invention my roller bearing, as illustrated in Figures 1 and comprises two complemental members 1 and 2 each having an interior channel 3, recesses 8 for the rollers, orifices 1 for bolts; bores 5 'for the spindles of the rollers, and oil passages 6 leading respectively to the channel 3 and to the roller spindles contained in the bores 5to automatically lubricate the same. 7 When the parts are assem bled a bushing 7 is entered in the channel 3 the interior surface of WhlChbLlShlllg being preferably spirally grooved as at 7 in order to form channels or passages for the oil. I
The roller spindles 9 each carries an enlarged longitudinally disposed eccentric portion 9 the ends of the said spindles be ing squared at one extremity as at 9 for convenience of manipulation, the other ends of the same terminating in a threaded part 9 adapted to be engaged with a nut 10;
My tubular rollers 11 are entered into the recesses 8 at the lower part of the body members and enclose the said eccentric portions 9 of the spindles, one end 9 of the latter extending outwardly from the bearing at one side thereof and the other extremity projecting from the other side of the bearing and beingheld to the same in operative position by the nuts 10.
My roller bearings are located adjacent to the ends of the ink roll spindle 13 on opposite sides of the press between the spindle supportsand the ink roll and the bearings are then mounted on the bearers 12 of the plate cylinder 12, which bearers lie adjacent to t is outer faces of the plate cylinder, By ieesening the 1' the ends 9 the t is eccentrics 9' around and thereby raising or lowering the rollers 11, whereby the plane of the centres of the rollers 11 and the axis of the ink roll spindle 13 may be caused to lie at different distances apart, the effect of which will be to raise and lower my roller bearing as a unit and thereby cause the ink roll to be so adjusted as to approach or recede from the plate cylinder at will. After the rollers 11 have been carefully adjusted to the proper operative relation so that the ink roll will be at its proper location relative to the plate cylinder, the nuts 10' may be screwed down tight thus holding the working parts of my roller bearings permanently in place, on account the latter lying so close to the ink roll, and preventing any sagging of the ink roll atthe centre thereof.
In the embodiment of the invention illus trated in Figures 3 andd the body of my roller'bearing is also made of two complemental members 14- and 15, the member l l being formed with a yoke or 'U-shaped recess is in which the central part of the member 1-5 fits, both members terminating in bifurcated or yoke-shape portions 14, 15., to hold the rollers 11 both members having the central channel 3 and bushing 7 as in the other embodiment. In this instance, however, the spindles for the rollers comprise plain bolts 16. formed withian orifice 16 at the smaller ends'in which any desired holding device, as a pin, be inserted.
The member 15 is made with an extension 15 having a threaded orifice in which a screw 1'? may work. When the parts are assembled on the spindle of the ink roll as before, the relative position of the body members may be, regulated by manipulating the screw 17, the end of which bears against the cross piece of the yoke 14, whereby the plane of the centres of the rollers and the axis of the ink roll spindle may be caused to lie at different distances apart thus raising or lowering the ink roll; at will.
After the parts are once placed in the proper adjusted and operative position they may be permanently held there by the said screw 17 and the set screw 18 which bears against the bushing 7. This roller bearing may have oil ducts similar to those already described, the same being omitted in the drawings of this embodiment for clearuess of illustration.
'I wish it to be understood that I do not mounted on the spindle of an ink roller and supported by said bearer, rollers carried by the said body, eccentrics mounted in the rollers, and means to vary the distance between the plane of the centres of the rollers and the axis of the said spindle by turning the shafts of the eccentrics for purposes of adjustment.
3. In a devlce of the classdescribed, an
, ink roll spindle, two body members. mounted on the spindle, said body members having interior channels and bushings to' enclose the spindle and enlarged lower portions and rollers carried thereby, means to adjust the position of the rollers, the said body members also having means to rigidly hold the two members together after the adjustment of the rollers. r
4.]In a device of the class described, a plate cylinder, a bearer therefor, a roller bearing having a body-portion mounted on the spindle of an ink roller and supported by said bearer, rollers carried by the said body, eccentrics mounted in the rollers, and
means to vary the distance between the plane of the centres of the rollers, and the axis of the saidspindle by turning the shafts of the eccentrics for purposes of adjustment, and also means to hold thebody in its adjusted position by locking the body and eccentrics together.
