WITNESEIEE v UNITED STATES PATENT OFFICE.

HENRY JOHNSON, OF NEW YORK, N. Y.

PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 548,711, dated October 29, 1895. Application filed August 10, 1 886- Serial No. 210,508, (No model.)

To all whom it may concern.-

Be it known that I, HENRY JOHNSON, a citizen of the United States, residing at No. 33

'East Twenty-second street, in the city, county,

and State of New York, have invented a new and useful Improvement in-Printing-Presses, of which the following is a specification.

My invention relates, primarily, to improvements in the job-printing press known under its trade-mark as the Peerless Press, and, secondarily, in such other job-printing presses as they may be adapted to and for; and the object of my invention is to bring the ink distribution up to the full capacities of such presses in other respects. I attain this ob- 'ject by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows the press and fountain in side elevation. Fig. 2 shows the same in vertical sectional view. Fig. 3 shows a plan or top View of the disk, ink fountain, and rollers and the form-rollers; and Fig. 4 shows a vertical sectional view of the same.

Similar letters refer to similar parts throughout the several views.

Hitherto all job-presses known to me in which the ink is taken from a fountain and distributed upon a revolving disk or plate have been limited in their use and adaptations to work of a more common quality, in

, which very uniform distribution of ink was either not necessary or where the want of it was not noticeable. In all such job-presses it has hitherto been found impossible to produce an even or satisfactory distribution on a class of work where a solid body of ink was to be used or colors were to be applied, and also on cuts or half-tone work, or where fine tinting efiects were necessary. By the aid of my invention I am able to bring the inkdistribution in such job-presses up to the full standard of the capacity of such presses in other respects, so that work which has heretofore been done upon large power-presses em ploying abundant cylinder distribution can be done upon such job-presses with perfection up to their capacity and the size of their forms, and these are the objects of myinvention. To accomplish this purpose,I combine cylinder distribution with revolving-disk distribution with such efiect that the ink, either in light or in heavy body, at will is distributed upon the disk without streaks and with perfect uniformity throughout, and also upon the form.' i

' In the job-press shown in the drawings the power to take the impression is obtained through a treadle T, crank-shaft C, and pin-' ion P, operating on the circumference of a drivingwheel W several diameters larger than the pinion and placed ona second crankshaft C, the crank of which moves in a slotted member of a toggle M, the toggle of which it is a member being connected, through its other member M, with asecond toggle in such a manner as to operate the same, this second toggle M and M being so related to the platen as to cause the platen to move to and fro in taking the impression.

The bed B in the press shown is stationary .and the platen P moves under the control of other end to an arm which operates the frame. of the form-rollers.

The strain of the impression is thrown upon two side tension-bars S S, preferably made of steel, when the secondary toggle is straightened. The press being so made, great power is obtained in excess of what can be obtained where the impression is made through a simplecrank motion. Consequently a form can be printed properly of a much larger size than in otherpresses where the original power is less.

In a press made with the double toggle, as

described, sufficient power can be'obtained to do embossing efficiently.

I employ an ink-fountain F, which is secured to the press through arms or brackets A, to which the fountain is hinged at jointsv J in such a manner that the ink-fountain e'xtends over the revolving disk'D, made to' revolve in any usual manner. 'This fountain rests upon an adjustable stop at some point forward of the hinge, whereby the fountain and the several rollers or cylinders supported on or by the fountain, as well as the fountain itself, are all adjusted or adjustable in relation to the revolving disk D and the several form-rollers. I prefer to use a screw-stop G, which is secured in a part of the frame supporting the fountain, so as to be screwed up or down, and .thereby automatically raise or lower the fountain resting thereupon. Of course it is evident that the same object could be accomplished by locating a screw for adjustment having a bearing upon the fountain or upon some extension of the same back of the hinge; but I prefer the arrangement shown in Fig. 1 of the drawings, where the adjustment is effected in the manner and by the mechanism above described. This inkfountain is provided with a well-roller or ductroller R, which first takes the ink from the fountain. suspended and jour-naled in the arms A A, by means of which the distance of the ductroller from the knife-edge may be controlled through or by means of the thumb-screws T T and the increasing or diminishing of the space between the duct-roller and the knifeedge may be effected thereby, so that the mass or body of ink taken up by the ductroller to be eventually transferred and distributed upon the disk may be increased or diminished in a manner well known; but the duct-roller may be stationary or journaled in stationary bearings, and the knife-edge may be varied and made to leave more or less space between the knife-edge and the ductroller in any ordinary manner for the same purpose.

The transfer and distributing roller R is, a composition roller, the function of which is to receive the ink from the duct-roller R and transfer it to and distribute or spread it upon the distributing roller or cylinder R The distributing-cylinder R is preferably made of metal and much larger than either the ductroller or the roller R. The rollers R R and R are the ordinary form-rollers, secured in the roller-frame F in any ordinary manner. These three form-rollers (one or more of them) receive the ink (already well distributed) from the distributing roller or cylinder R and, aiding still further distribution, transfer the same in the first instance to the. revolving disk D. Where the location of the cylinder R and the throw of the frame are such as to bring the form-roller R only in contact with the roller R the effect of the movement of the parts for this purpose is as follows: In the upward movement of the formrollers the roller R comes in contact with the roller R which, being journaled in, the slots S S of the arms A A, rises so as to allow the roller R to pass thereunder. The continued upward movement of the roller R in contact with the roller R causes the roller R to revolve upon and with the roller R the roller R at the same time parting with ink already partly distributed by distributing the same again or, further, upon and by the aid This duct-roller R is preferablyof the form-roller R the rollers R and R being again brought in contact and rolling one upon the other, the rollers R R and R are rolled in the opposite direction,thereby causing a still further distribution and spreading of the ink upon the roller R the rollers R and R being again raised in their slots in the operation. As this last movement is com: pleted, the roller R again drops, but not at first in contact with the roller R, being permitted to drop by the dropping of the roller R with which it is in contact. However, the roller R preferably remaining in contact with the roller R the contact of the roller R with the duct-roller R is prevented until the form-roller passes beyond the roller R toward the form. The ink thus distributed upon the roller It by the further downward movement of the form-roller frame is distributed upon the revolving disk D in such a manner as to leave the surface of the disk covered with a layer of ink of uniform thickness and appearance and without streaks. During these operations, in which the roller R automatically revolves and operates the transfer-roller R and the distributing roller or cylinder R the form-rollers R and R traverse the disk upward and downward, aiding in-the first place to still further distribute the ink upon the disk D and at the same time upon their own surfaces, these two last-mentioned roll ers, together with roller R by the further continued movement of the roller-frame applying the ink in uniform thickness and without streaks upon the form preparatory to the printing,which takes place in the interval during the period within which the form-rollers are traversing the disk in the operations heretofore described. After the roller R parts contact with the roller R? in the downward movement of the roller-frame, and before it again makes contact therewith in its next upward movement, the rod N, attached to the roller-frame F, operates the ratchet-arm E, thereby causing the duct-roller R to revolve a stage, taking upon its surface an additional supply of ink, and also at the same time transferring an additional supply of ink from the forward part of the roller R to and upon the roller R, which is revolved to an equal extent through its contact with the roller R, made for that purpose, and the roller R is also revolved by the roller R, the roller R at the same time transferring and spreading its ink to and upon the roller R The roller R, being a composition roller and having tack, hugs or adheres to the roller R sufficiently to insure its revolution, and thereby effect both the transfer and the spread of ink upon the roller R It may shrink or diminish in size without material injury to its functions in the operations heretofore described; but the roller R being made of metal, and therefore unchangeable, and being provided with a uniform surface, will always perform the functions of transferring the ink to and distributing it upon the form-roller with uniformity of action.

By giving an additional throw to the formroller frame or additional extension to the ink-fountain and its attachments over and upon the disk the form-roller R can also be brought into contact with the roller R in such a manner as to repeat the operations and effects of the roller R upon the series of rollers R and R as previously described, and the same statement is true as to the roller R but I have not found it necessary to bring either the roller R or the roller R in contact with the roller R for the reason that within a wide range of distribution required I have found that the contact of the roller R in the manner described with the roller R was suflicient to produce the most perfect distribution over the entire form even where the form was of the largest size known to job-presses and where the body of color required to be printed upon the paper was substantially solid throughout, and by proper adjustment of the parts shown and described I have found it possible to effect perfect and uniform distribution in this manner where the tints were most delicate and where the shades of color were most difficult to deal with in their contrasts With the color of the paper or other material upon which the printing was done.

Prior to my invention it was customary to bring the upper roller of the form-rollers in contact with the duct-roller secured, operated, and adjusted in the ink-fountain substantially as the roller R is operated and adjusted in the fountain F, or in some other manner. In these arrangements the upper form-roller acted as a transfer-roller, taking the ink directly from the duct roller, and also as a distributing-roller, distributing or spreading the same upon the disk, aided in that operation by the second and .third form-rollers; but in this method of distribution it was found to be impossible to distribute the ink uniformly upon the revolving disk so as to print solid bodies of color and. delicate tints. In another form or method of distribution (shown in my application, Serial No. 182,058, filed November 6, 1885) the distribution is improved or increased by placing an intermediate roller in an extension of the arms of the ink-fountain, journaled in slots, by the aid of which an intermediate distribution is obtained upon one or more of the form-rollers prior to the distribution from those form-rollers, one or more, upon the revolving disk. In that case, as in the other just described, it is one of the functions of the most forward of the form-rollers to take ink from the duct-roller and act as a transferroller in transferring the ink to the disk, the

intermediate distribution taking place between the roller journaled in slots in the arm extensions referred to and the transfer formroller.- I found that the intermediate distribution referred to, obtained in manner described, greatly improved the distribution upon the revolving disk, and consequently the distribution upon the form, and this to such an extent as greatly to increase the capacity of the job-press, and to increase it suffi ciently to enable the job-press to satisfactorily perform Work or do printing that formerly could only be done upon presses in which cylinder distribution was employed ;but in my presentinvention neither the upper nor any other one of the form-rollers is allowed to come in contact with the duct-roller or take ink directly therefrom, the transfer action of the form-rollers and contact being limited to the transfer from and contact with the distributing cylinder or roller R to and upon which the ink is first distributed by and through the composition roller R, as previously described, since the roller R itself is so arranged as not to come in contact with the roller R, but instead with the roller R. In this manner I have obtained in the jobpress a combination of disk and cylinder distribution which increases the capacity of the job-press greatly and equalizes its ink-dis tributing qualities with its other qualities, especially that of taking an impression.

I am aware that the combined cylinder and disk distribution shown in my invention can be .adapted to other job-presses in which revolving-disk distribution is employed besides that described herein, and in which there is less power or capacity only for a smaller amount of pressure upon the form, owing to difierent organization of the press from that described herein, and therefore I do not desire to limit my invention to presses in which the impression is given by the use of the toggle-joint, as shown; neither do I desire to limit it to a press in which the impression is given by power applied through a double toggle, as shown herein, since, having brought the distribution up to the capacity of the doubletoggle power, the same distributionwill manifestly answer for the press wherein the power for the impression is obtained by means of a single-toggle, and in all these presses the same power that operates the roller-frame may be made to operate automatically the cylinder distribution shown in this invention.

The hinging of the ink-fountain as shown and described prevents any injury to the press during the movements of the form-rollers to and fro, since the ink-fountain itself will be lifted in case the journals of the rollers R and R bind in their slots or any other contacts are made with any other portion of the fountain,and at same the time the fountain may be adjusted readily, so as to give more or less contact between the form-rollers and the roller R in themovements of the former:

back and forth, this adjustment also necessarily effecting correspondingly the movement of the roller R as well as the distribution of the ink. I do not, however, desire to limit my invention to the instances in which a hinged fountain is used, since the roller R being journaled in slots S S and no contact between the form roller or rollers and the duct-roller being required, a stationary fountain might be used in the place of the hinged fountain shown without avoiding my invention. I am also aware that the arms A, in which the rollers R, R, and R are supported, may be firmly secured to the fountain or otherwise made an immovable part of the same, provided other and well-known means are used for controlling the knife-edge in its relation to the duct-roller and thereby the amount of ink at any time to be taken from the fountain by the duct-roller.

I am aware that additional rollers may be added to the system of rollers which take the ink from the duct-roller beyond roller R and in this way the distribution may, if necessary, in the case of heavy inks, be carried still further; but the three rollers shown will be found sufficient for all ordinary purposes. I am also aware that the slotted cam part of the toggle member M may be secured to one member of the toggle M M with the crankshaft C arranged to move and operate therein for the purpose of giving the necessary vibratory motion and power to the platen P, and when this is done the system of ink distribution herein shown will be found amply sufficient for all purposes Within the capacity of a printing-press so organized.
