Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed May 21, 1903. Serial No. 158,148.

To all whom t 'may concern:

Be it known that I, HENRY F. BECHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Printing-Presses; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form partof this specification.

This invention is an improvement in stationary-bed traveling cylinder web perfecting presses, of the Cox-duplex type, such as shown in the Patent to Jos. L. Cox, llo. 478,503 of July 5, 1892.

The object of the present invention is to provide such a press with a third printing couple located above and parallel with the other beds and cylinders, and capable of being used conjointly therewith to print a large newspaper, or of being placed out of operation when it is desired to print a smaller paper. By the employment of this upper extra bed and cylinder the size of the newspaper which can be printed on an ordinary duplex press can be increased one half, and produced in the same time that the ordinary sized paper can be produced. This improvement adds materially to the utility and productiveness of the machine, largely increases its capacity for work, and renders it capable of producing any size of news papers up to l2 pages, at each operation.

The essential features of the invention and the novel parts and combinations thereof for which protection is desired will be summai-ized in the claims, and are fully understood from the following explanation, and accompanying drawings.

Figure l represents a diagrammatical longitudinal vertical section through the complete machine, showing the arrangement of beds and cylinders, and web feeding and guiding mechanism. Fig. 2 is a broken top plan view of F ig. 1. Fig. 3 is an end view. Fig. 4 is an enlarged side elevation of one of the cross heads, and Fig 5 a detail vertical section on line 5 5 Fig. 4.

A, A, A2 designate three type beds located above one another in three superposed parallel planes; coacting with each type bed is a cylinder B, B, B2 which are journaled in reciprocating cross heads mounted in guides on the opposite side frames of the press, said cross heads carrying web guide rollers Z), ZJ, o2 on opposite sides of each cylinder, and suitable inking mechanism, (not show-n) as commonly used in these presses.

The main web comes from a roll W passes through the feed rolls or devices C, in passing which it is longitudinally divided by a slit-ter c, it passes then under a stationary guide d, up over a looping roller e, down under a fixed guide a, over rollers b, under cylinder B, to a guide and coaXing roller d at which point the two portions 10 w of the main web separate. The part Iw of the web passes up over a guide and coaXer roller Z2 back over rollers 5 and under cylinder B to a stationary guide a thence down under a looping roller e', over a stationary guide d3, and thence over suitable guides to and between the delivery rolls or devices F, from whence it passes to the folding mechanism. The part w of the main web passes from roll d onto a deflector which may be composed of angle bars or rolls D D by which it is brought back above and in line with the part fw, but passes up to and over a stationary guide and coaXing roll D parallel with and above roll-cl2, thence it passes under guide D2 to and over guides b2 and under cylinder B2 to a stationary guide a2, down under a looping roller e3, over a stationary guide D3, to the delivery rolls G, G, or other suitable delivery mechanism, by whence it passes over suitable guides to the folding mechanism.

The web to2 comes from a second roll W, conveniently located at the front end of press, or elsewhere if desired, and passes over suitable guides above the top bed and cylinder to the rolls G, G', at one side of web fw', passing rollers G oppositely to web w', so that the two webs are fed opp'ositely by the rollers, as indicated in drawings. Thence web to2 passes over guide H, under stationary guide H up over looper e2, down under guide H2 up over guide a2, to and over guides b2 under cylinder B2, to and over a coaXer H3 above and parallel with roller cl2 down under guide H4 back to and over rollers b and under cylinder B to guide a down under looper e over guide Z3 to delivery rolls F, as shown in the drawings.

From the foregoing description and drawings it will be noted that the webs fw, w', lie side by side and move in same direction over bed A and under cylinder B, receiving the first impressions from forms on bed A. That web w is then returned directly between the cylinder B and bed A receiving perfected impressions from .type on bed A, and passes thence to the delivery, this being the course of the web in the ordinary twohigh bed and cylinder COX-duplex press. It will also be seen that the web fw after being first impressedy on bed A, is perfected by cylinder B2 on bed A2, (web yw being defiected so as to come over the length of web w overlying bed A,) web w being printed on beds A, A2. It will also be noted that web 1.02 is first printed from forms on bed A2 by cylinder B2, passing between said cylinder and bed in a direction opposite to the web w, but running beside the latter; web w2 is then perfected from forms on bed A by cylinder B. ruiming between said bed and cylinder beside and in the same direction as web fw.

'lVeb 102 is fed into the press by the same mechanism which feeds out web w, and for this purpose it is preferable to make the part of rolls G which feed. in web 102, very slightly less in diameter than the part which feeds out web w, or to so construct the combined feeding and delivery mechanism that the web will be fed out sufficiently fast to keep it taut, and fed in sufliciently fast to supply the demands of the press. Further web w2 is fed out and delivered by the saine mechanism and at the same speed as web w.

The several looping rollers e, e, e2, c3, may all be mounted on the same equalizer bars and moved synchronously by the cams E2, such as are employed in the ordinary duplex presses. The feeding and delivery mechanisms correspond in construction and functions with those of said duplex presses and are such that the webs are continuously fed to and delivered from the printing mechanism, while the portions thereof extending between the beds and cylinders are momentarily stopped during the actual printing periods, as described in said CoXs patent.

The two lower cylinders A, A, are journaled in cross-heads I having internal ribs I guided in ways I2 on the side frames of the press, and reciprocated by means of pitmen J connected to crank wheels J on the main drive shaft J 2 as in the ordinary dupleX press. The upper cylinder B2 is journaled in cross-heads z' having internal ribs 2'. guided in ways 2 on the sides of the press above bed A and parallel with guide ways I2. The cross-heads I, z', might be integral, but I prefer to make them separate and provide means for rigidly but detachably connecting them, so that when connected they will reciprocate as one, and the necessity for eXtra driving mechanism for the upper cylinder be avoided.

As shown the cross-head z' is provided with a depending lug 3, which lits a recess I in the adjacent cross-head I; a stud IL is rigidly secured to this cross-head I and passes through the lug i and is bound thereto by a nut 4, (see Fig. Lt). This forms a simple rigid connection between cross-heads I, z', while permitting ready detachment or separation thereof. This lug 3 is on the end of the crosshead nearest the drive wheels, and is put in this place because the greatest load when reversing comes on the fast center, and with the lug in this position, the strain of the load does not come on the stud. The load on the stud occurs when press is passing over the slow center, and the strain is very light as compared with that of reversing.

Then it is desired to print only a small, or eight page paper, the cross-heads z' can be disconnected from cross-heads I, after being moved out to the farthest position to the right, and the upper cylinder will then remain idle during the operation of the others, the lpress then being threaded and operated as an ordinary duplex press.

To recapitulate briefly, the operation of the press is as follows, when printing a twelve-page paper, the main web is inches wide-which is the width of the ordinary eiglit-page roll. This web, however, is split when passing through the lower feed rolls, as shown, and of course passes through the lower printing couple as two independent webs. After passing the lower printing couple, both webs pass under coaXer roll marked CZ. At this point, the two webs separate, one w passing over guide (2, on the drive side of press, and through printing couple on middle bed, then through the equalizers to the delivery in the usual manner. Now, going back to where the webs separate at CZ, the web i0 on plain side of press passes over angle-bars, and over coaxer roll D, and through printing couple on top bed, on drive side, and then on through the top equalizer and into the upper delivery.

The four pages which are printed on the lower bed, are backed up l on the middle and upper beds, that is, the opposite sides are printed on the middle and top beds. This is done in order to run the four-page web from paper roll IV on the plain side of press--a straight-line run-without passing over any angle-bars until after passing into the folder.

The first printing on the four-page web wg from paper roll 1V is done on the top bed, on plain side of press, after which it passes over coaxer roll H?, and down and under coaXer roll Ht, and then through printing couple on middle bed, on plain side of press, and then through the equalizers in the usual inannei, and into the upper delivery.

The rolls G have two sizes. This is necessary in order to have a little more speed on drive side of press to comb the web after passing through the printing couples, and be of proper size to feed the right amount of paper on the plain side of press.

The upper cross-head, which carries the upper cylinder, may be detached from the main cross-head, which carries the two lower cylinders. Then thus detached, only the two lower beds are used, as when printing eight pages, or less.

lVhen changing from a twelve-page paper' to a ten-page paper, it will only be necessary to use a 53 inch roll instead of the T0 inch, and run through in the manner heretofore described, having the narrow portion of the web, after being split at lower feed rolls, on drive side of press, and the two-page width on plain side. This narrow web should pass through the lower and middle printing couples, and when folded, the narrow sheet is between the two four-page sheets. This is done for the purpose of keeping the narrow sheet in place, and when the paper is opened it will not leave the position in which it was placed by the folder.

It is preferable to superimpose the two halves of the wide web and print same, one on the middle bed and the other on the upper bed. rIbis is done to avoid turning the web L02 completely over, for if the web were turned completely over, it would be necessary to turn so many angles that it would malte it dangerous for web shifting in the printing couples, and especially where the web has to be shifted intermittently. It would be easy to do if the web at this point was continuously running, but it is very diiiicult to do with an intermittently shifting web.

Color printing may also be done on this machine, and more colors used than on the eight-page duplex press. For instance, the narrow, or, as it is commonly called, fourpage web, which is printed on the plain side of press, after passing through upper feed rolls, is passed around roll H, and H, over equalizer roll e2, and around roll H2, up and over roll a?, over roll b2, under cylinder B2, over roll 62, over roll H3under H4, and over Z1', under cylinder B, over b, and over af, around e, over (Z3, and into the delivery rolls F, then in the usual manner around the anglebars and up to the top of the former, and then, instead of going into the folder, is carried back to the feed rolls C, on drive side of press, led therethrough, and then passed in the usual manner through the first printing couple A, B, then around coaxer rolls (Z and (Z2, through the second printing couple B A, over the equalizers or loopingl rollers, to the delivery rolls and back in the usual manner to the top of the former, and down into the folder. It will be observed from the foregoing description, that this particular web passes through two of the printing couples four times-two on plain side and two on drive side of press. Meanwhile, a four-page roll is placed in the machine, on plain side of press, and is printed in first printing couple, on lower cylinder B, then passed around cl', and around the angle-bars, vand up over coaXer roll D, and through the upper printing couple on drive side of press, then passed over the equalizers or looping rollers to the delivery rolls G, and is assembled with the first web at top of former, this method of threading the webs will produce an eight-page paper in colors.

The invention is not restricted to the mechanical embodiment thereof illustrated in the drawings, nor to the particular construction of printing couples, or feeding and delivering mechanism, and
