Specification 6: Letters Patent.

Patented May 27, 1913.

Application filed January 2. 1912. Serial No. 668,868.

To (It! whom it may concern:

Be it known that I, lIANs LOUIS Jensen, a citizen of the United States, residing at Dayton, in the county of ltlontgomery and State of Ohio, have invented certain new and useful Improvements in Printing- Presses, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to printing presses and more particularly to printing presses designed for printing bills or other forms, the production of which requires a series of printing operations. For example a bill of lading requires four separate n'inting operations, it is printed on both sides, the successive bills are consecutively numbered and a red ink number is printed on the face of the bill to indicate whether it is an original, second or third copy. In addition the bills are punched to form therein he desired apertures. As now constructed many of the machines which will produce these bills are very large and not only occupy much valuable floor space but are very expensive. Moreover, the arrangement of the usual machine is such that the printing rolls and the cooperating parts are not readily accessible, the setting up of the machine or its prepw ration fpr printing a given form being rendered very ditlicult.

The object of the present invention is to 'pwvidc a press to produce forms or bills requiring a series of printing operations which will be very compactly arranged so that it will occupy a relatively small amount of space; and which will have its printing rolls so arranged that they will be readily accessible and of such a construction that the plates can be quickly and easily attached to and removed from the same, thereby enabling the machine to be quickly and easily set up for a particular piece of work.

In the accom )anying drawings, Figure 1 is a section ta (on just inside one of the frame members and showing the gearing carried by both frame members in dotted lines; Fig. 2 is an elevation of the printing roller showing the means for attaching the plates thereto in section; Fig. flis an end view of the same; Fig. 4 is an end View of the lower section thereof; and Fig. 5 is an end view of the upper section thereof.

In these drawings l have illustrated one embodiment ofnn' invention and haveshown members of the respective couples in an up the same as comprising a frame formed of two upright members 1, only one of which is illustrated in the drawings, the other frame member. being a duplicate of that here shown. The frame is of a relatively great height and, in the present instance, its height is considerably greater than its length. At its front and rear ends the frame is provided with supporting devices for paper rolls, that device at the rear end of the frame being adapted to support the supply roll from which the paper is fed to the press and the device at the front end of the machine being adapted to support a rewinding roll upon which the printed forms are wound. While these supporting devices may be of any suitable character I have shown each as comprising a pair of arms 2 mounted on a transverse shaft 3 mounted in the side members of the frame. Each of the arms 2 of each device, of which but; one is here shown. is provided at its free end with a half bearing 4 adapted to receive the end of the su 'iporting shaft 5 for the paper roll 6. Mounted upon the frame in a fixed position are segmental bearings 7 arranged t t} cl'itipcrate with the half bearings 4 of the arms to retain the rolls in position when the arms 2 are in their upright position. A lever 8 is rigidly se ured to the shaft 3 and by manipulatin; this lever the arms 2 can be lowered into a substantially horizontal position and the roll of paper rolled between the arms with the projecting ends of the shaft in a position to be cn u ed by the a to half bearings when the arms are elevated, thus causing the elevation of the arms to lift the roll into its proper position, as Shown in the drawings.

Tn order to arrange the mechanism as compactly as possib e and at the same time have the parts thereof readily accessible I have arranged the mechanisms which act upon the paper-about the edge of the frame, and the paper as it is guided through the several mechanisms from the supply roll to the rewindihg roll travels in approximately an inverted U-shape path. The present device comprises three rotary printing couples, each comprising a printing roll and a platen. Two of these printing couples are arranged near the front and rear ends of the frame. respect ively, a re mounted in such positions that the paper will pass between the two ward and downward direction, respectively. and are. so arranged that the printing roller is reuilily accessible A. third priiningcouple i arranged near the top of ihe frmne :illll is so mounted that the paper will puss between the two nu rulers of the couple in :1 enlist-2n tiully horizontal plane. The first pr nting ouple which is arranged near the rear edge of the frame comprises a printing roll 9 and a platen 10 mounted on shafts ll and 12, respectively, which, in lurn, are mounted in bearings formed in the frame near the edge thereof. The axes of the two nnernbers 10f the couple are arranged transversely-t0 the height of the machine but an an irr lination to the vertical. This arrangement permits the paper to pass upwardly between the two members of the simple and the same time supports the printing roll, which. in the present arrangement, is the upper roll. in such a pcsiiion that it is reudily ac.- essible to the operator. One of the rolls is movable relatively to the other To inrow off the impression, and, in the present in stance, the platen is mounted in an eccentric bearin 13 which permits it to be moved away om the printing or form roll. The inking mechanism for the form roll is of a known character and is indicated as 21 whole by the reference numeral 14-. The paper is guided from thesupply roll between the two members of the printing couple by passing the same first about guide rollers or drums 15, thence about; a guide 1.6, thence between the two members of the couple and about a guide 17 from which it extends upward about another guide l8 carried by the ink ing mechanism, thence to the second couple which is similar in construction to that. just described and comprises a platen 19 and a printing roller 20 arranged to print on the opposite side of the web from that printed upon by the printing roll 9. The axes of the two members of this rotary couple. are ar anged in an approximately vertical. plane so that. ihc paper nill pass between the same in a transverse direction. The )lzinc of the axes of the two n'icinbers lies between inc paper roll supporting devices and the print ing couples wl'iicl'i are arranged iil'iovc the some and thus rill ws the psi-is lo lrc. compnctly arranged, The ihiiwl printing couple comprises :i platen J1 and a painting" roll 22. This latter roll, however, not the ordinary form r ll but 1' moun ed thereon :1 eri s of liliiilll cs adapted i'o print cmisccutive urmliers upon iii sneer-s ive bills or forms as they pus; beluwcn the two members of the. printing couple The (letuil c nstruction of this numbering device is not. :1 part of lhe prlw wt inventi n and llifiltl lil'tl, not lierilv l'i urel in detail, ll. being sulli icnt for ilw pur 'm e of ilH presei'lt'inwnti n to sizilv that the two members of the couple are rolury and in their broad aspects are similar to the rotary members oi the other printing couples. The inking devices for ilic second and third printing coupics, which are imlicatcd ii! 93 and 24, rcspcctively, are of ordinary construction and require no description in connection with the present in vcnlion. A punching device comprising two rotary meml'iers 25 and 26 adapted to form the desired perforations in the bills is mounted in the frame between the third printing couple and the re'winding roll 6. Here again the detail construction of. the punching devices is not 2. art of the invention and is not here described, it being sufficient to state that these punching devices comprise two members rotatable about parallel axes.

The several operating devices may be driven in any suitable manner but preferably by trains of gearing mounted upon the two side members of the frame and connecting the several moving parts with a suitable source of power.

It will be noted from the, foregoing description that the printing rolls 9, 20 and 22 are arranged in such positions that they are readily accessible from the exterior of the machine. To further facilitate the setting up of the rolls 9 and 20, that is, the applying thereto of the printing plates, I have so constructed these rolls that the plates can be quickly and easily clamped thereto. To this end I have divided each roll longitudinally to form two sections, the lower section being here indicated by the reference numeral 2 andv the upper section by the reference numeral 28. The lower section is mounted on the shuf, which. in the use of the first couplc, is indicated by the reference 11 and the upper sectimi 28 movably connected to the. lower section. Preferably this connection is a hinged one and is formed by a longitudinal hinge pin 29 extending throu h aperturcd lugs on adjacent portions oi the respective ctions of ihe roll.

The iv'o sections of the roll may be moved relatively one to the other in any suitable manner to expand and contract the roll. in the present instance I have shown a link 30 mounted on a stud 31 rigidly secured to one end of the upper section 28 and extending across the adjacent surfaces of thctwd sections of the roll and mounted upon an ecwntric pin carried by a stud 33 journulml in ie lower section 27 of the roll. The pin 32 provided on its outer end with a nurwl .u Ill adapted to reccivc u wrench to enable ll'ustud to be rotated. It will be zip iizreui hat the rotation of the stud will w ciztiic pin to more rclulirely l -r-ciion oi the roll and, conseiii i nlr. will be actuated to more the u ri-r i l relativ ly to th lower se iion. ln u, the parts may be locked IV have provided in iiirir :2

iri

the link with an extension extending beyond the stud 33 and having therein a slot 35 to receive a cap screw 36 which extends into the end of the roll and by means of which the link can be locked against movement relatively to the lower section of the roll, thereby locking the two sections in their adjusted positions. Suitable clamping members are mounted on the exterior of the roll l and cotiperate therewith to hold the plates in position thereon. In the present instance these clamping members comprise rings 37 extending about the roll and having op-l positely extending flanges 38 adapted to extend over lips or projections 39 formed on the ends of the plates, which are shown at 40. The arrangement of the two sections of l the roll is such that when in their expanded i positions they will form a substantially true cylinder and conform to the inner circumference of the plates. The clamping rings that when the sections 37 are of such a slze have been expanded into substantially true cylindrical form the projections 39 of the plates" will be held firmly between the flanges on the clamping rings and the body of the roll, thus quickly same in position.

and easily securing the 1 It will be understood that 1 the plates are formed of substantially semi- 1 cylii'idrical form and are placed in position 1 on the form and the clamping rings slipped 1 over the projections on the ends thereotl The (it of the parts is sufiiciently close to l retain each plate temporarily in position. i The next adjacent plate is then slipped into position on the other side of the ring and an- 1 other clai'npin 7 ring applied to the opposite end until all t e plates are in position. The roll is then expanded and the several plates clamped in pla e. all of which can be done very quicldy and easily. This mechanism combined with the readily accessible positions of the form rolls enables the forms to be rpiiclily and casily applied and adjuslcd on the rolls and results in a grcal saying of 1 time and labor orcr the system now com m nly in usc.

ihi- Hlflljll'lflli of thc device will be readily ur rslond ir n: the foregoing description au l it will be appai'cnl that thc machinci nhich l have prodiiccd irof a rcry ompa t arrangement. \hc parts being mounted in such a manner that the organized machine occupies but a small am unt of space: and further that the several parts are readily a essible from the cxlcrior of the machine and are of such a character that they can be 1 cxtcri r of said sci-lions and quickly and easily manipulated to prepare the machine for operation.

'While I have shown and described one embodiment of my invention it will be und'erstood that this has been chosen for the purpose of illustration only and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:-

l. A printing roll comprising a plurality of longitudinal sec'tirms movably connected one to the other, means for moving one of said sections relatively to the other, and clamping rings extending about the exterior of said sections and adapted to engage the printing plates, whereby said plates may be clamped to said roll. i

2. A printing roll comprising two longitudinal sections pivotally connected one to the other, a link piyotally connected to one of said sections. a pin eccentrically mounted in the other of said sections and extending through said link, whereby the rotation of said pin will more one of said members toward or away from the other, clamping rings extending about the exterior of said sections and adapted to extend over the edges of the printing plates, whereby the ex pansion of said sections will cause said plates to be clamped between the sections and the rings.
