To all whom it may concern: 7

Be it known that I, HENRY F. BEOHMAN, of Battle Creek, in the countyof Calhoun and State of Michigan, have invented certain new and useful Improvements in a Combined.

Flat-Bed and Rotary Press; and I hereby 'declare that the following is a full, clear, and

exact descriptiori" thereof, reference being had to the accompany' g drawings, which form part-of this specification.- This invention is an improvement in printing machinery, a'nd its object is to providea combined..bed-and-cylinder-press with arotary-cylinder press in such mannerthat they may be used conjunctively to reduce large size papers or smaller'multi-co ored papers. In particular the invention is an im roved rotary pressatta'chment to -the -wellown duplex flat bed web perfecting printingpress, the rotary press being'arranged within the frames of the fiat-bed .press and driven from thepowershaft of such press and in such time with the other mechanisms of the flat-bed press that aweb for anewspaper of eight pages or lesscan be first printed on the.

ordinary du lex press and immediately thereafter printed in colorsupon the rot'ary'press before its delivery; Again .eight'pa es or less can be printed on one web by the uplex press and simultaneously eight pages or less printed on another web by the rotary'press, and the products of the two presses assembled in the usualv folder of the duplex press. Again therotary press may be used to print eight pages or less from stereotype plates while the type. forms are being'ma up for the flat-bed press.

Other will now describe the invention as illustrated in the accompanying drawings, in which Figure 1 is a diagrammatical sectional ele-, vation of a duplex combined flat bed and cylinder web perfecting press and a ro tary cylinder-perfecting-press operating on the same web; Fi 2 is an .enlar ed diagrammatical view 0 the rotary cylin er-presS and web-looping and guiding-devices Fig. 3 is a similar View showing how one web may be perfected in black an web printed in color on the'rnachine.- Fig. 4 is another diagram illustratin howtwowebs may be printed and assem ledin such a press;

A, A, designate type-beds, v with which practical utilities of the" combined presses will befherei-nafter explained, and I part of the same co-act reciprocating cylinders a, a, which are journaled in a common cross-head B, reci located by means of itmen B from craniiwheels B on a shaft as in the ordinary du lex ress: The'web w is led in'from the rol t rough continuously. feeding rolls 0, and then under guide roller 0, which may be one of the feed-rolls-up' over looping-roller (1, down under guide 0, forward over guide a between cylinder a and bed A, up over another "uide a back to guide 0 up over guide .baeli over' uide a, then betweenbed A andcylinder a, up over guide a to guide 0 down under looping-roller d, and then it ma be carried 'direct to the feeding-out rolls and pass'on to'the folder F. All the aforesaid partsare'constru'cted and operated as in the well-known duplex press, the ides c, c, 0 c and cf beingijstationary guides, while .the guidesa, a ,la-and a travelwith the cylinders. The feed rolls C and the delivery rolls'E are driven at uniform speed and feed theweb "wcon'stantly'toward and from the printing mechanism; The rollers d, (1, however, are mounted-u on reciprocatin bars D attached tolevers' ,"wbichare oscil ated by means of cams ID, attached to a cross-shaft D. and geared to the crank-wheels B, as indicated in the drawings. t The aforesaid parts are all constructed and operated as in. the ordinary duplex press, and substantially as shownand described in the patents to Cox, No.478','503, of July 5,1892, and No. 501,456, of July 11,1893.-

Located in the frame of the press between the" folding mechanism and the feeding and delivery rolls C and E, is. a rotary press or attachment, comprising two plate-cylinders G and and their co-acting impression-cylinder's g, it. These cylinders are arranged transversely of the press and may be driven by'any suitable gearin rom the shaft B on which the crank-wheels B are keyed. Asshown a gear B on said shaft meshes with a ear G on cylinder G. The cylinders G, g,

h, areinter geared as usual so as to have a perip eral .rhovement exactly corresponding with that of-the rolls 0 and E.

Sets ofinlting mechanism, indicated at I and i, are providedfor the'plate-cylinders G and H respectively, but as the particular means for" inking these cylinders is well known, I have simply conventionally illustrated the same in thei drawings,

In the duplex press "in order toshorten the travel of the cylinders a, a operating on the type-beds A,- A, the type-forms are arranged in one line, side by side upon said beds and transversely of the press, and a sufficiently wide web is used to enable the desired size of paper to be roduced. Therefore, in order to enable registering impressions to be made from the plates on cylinders G and H, upon the same web that is printed by the -bed and cylinder mechanism, it is necessary to employ duplicate forms or plates on said cylinders G and H. 7

As it is impractical to make lates to entirely surround the surface of t e cylinders G and H, the cylinders are made of such diameter that two du licate sets of forms or plates may be attac ed to each cylinder at diametrical y opposite sidesthereof, as indicated in the drawings; the plates S,"S, on the cylinder G are duplicates, and the alternate impressions produced thereby will register with successive impressions produced by the bedand-cylinder mechanism. The same is true Hof the forms S, S, on the plate-cylinder The combined presses may be used to print eight or less pages in colors on a single web, and when so used the ress is threaded as shown in Fig. 1. In this case, after the web has been rinted and perfected on the beds A, A, an passed to the delivery E, it is led back to a guide f then to and between impression cylinder 9 and plate-cylinder G then between impression cylinder h and cylinder H; then over ides f and (if, and thence to the folder as indicate in the drawings. In this manner any number of ages up to eight may be printed and perected in colors, and, obviously, in the same manner, eight pages could be perfected in black, and any desired number of such pages additionally printed in color. When less than the entire number of pages are to be printed in color, however, the entire web may e perfected on the beds, and then it may be divided at the rolls E by a slitter E, as shown in Fig. 2, and one-half w of the web may be led from the rolls E directly to the folder F and the other half web to may be led around the guide f, between the cylinders G, g and H, h to guide and thence over guide f to the former F, eing there assembled with the other part w'- of the web.

As indicated in Fig. 3 the web, instead of passing from roller 11 directly to the rolls E may be passed over guide f, through the rotary press to and over rollers f, then back to the delivery folder. In this way the web is acted upon by both the bed-and-cylinder-press and the rotaryecylinder-press inits passage between the feed rolls an the delivery rolls.

As indicated in Fig. 4 a web W may be printed and perfected on the bed-and-cylin- 5 der press, and carried direct from the rolls E rolls E, and t ence to the to the folder F,- and another web W may be led under a uide f then between the cylinders G, g,-- If h, and over guides f, f to the folder. In this way two independent webs are simultaneously printed one on the bed and cylinder press and one on the rotary press, and are assembled at the folder.

In order to use the cylinder press stereotype plates arenecessary, but where,newspapers of large size are to be printed, the'advertising and general matter can be made up in plate form and attached to the cylinders, while the telegraphic latest news items can be placed in .the type-forms for the bed-andcylinder press. 30

In the arrangement shown in Fig. 4, where two webs are printed, the press can produce papers of from six to sixteen pages varying by twos. Suitable mechanisms may be provided whereby the cylinder press and the bed-and-cylinder press can be disconnected if desired as by making gear B slidable on shaft B so that one may be operated without necessarily having to operate the other, and its capability for producing different varieties of work correspondingly increased.

While I have illustrated and described the invention as applied to a duplex press having two flat beds and reciprocating cylinders arranged in parallel planes, I do not consider my invention restricted to such arrangement of beds, nor to the articular number of beds shown, as it would e equally useful in connection with fiat bed presses of less or more capacity than that indicated in the drawings. And further, I do not consider my invention restricted to the em loyment of a flat bed press in which the f drms are necessarily arranged side by side in a single line, which necessitates theemployment of duplicate sets of plates on the rotary-cylinders, as if the stroke of the reciprocatin cylinders be sufficiently increased, as is we known, two or more rows of forms can be placed on the beds A and A, so that the o 110 posite forms on the plate cylinders G and II would not have to be duplicates, and would respectively register with the first and second rows of impressions produced from the first and second rows of forms on the beds.

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

1. In a printing press, the combination of a stationary bed -and a reciprocating cylin- 120 der, a. rotary plate-cylinder andco-alcting impression cylinder, means for continuously ee ding the web to and delivering it from the bed-and-cylinder, means for converting the continuous movement of the web into an in 125 .termittent movement thereof through the bed-and-cylinder printing mechanism, means for directing the web to and through the rotary printing mechanism, and means for operating the rotary printing mechanism in 139 unison with the bed and cylinder mechanism, substantially as described. a

2. In a printing press, the combination of a plurality of printin mechanisms each compns a statlonaryt cylin er, a lurality of rotary printing mechanisms, eac comprisin a late-cylinder and co-acting impresslon cy n er; means for continuously feeding the web to and delivering it from the'bed and cylinder printing mechanisms means for converting the continuous movement of theweb into an intermittent movement thereof through the bed a'nd cyled and a reciprocatingmy own, I two witnesses.

inder printing mechanisms; means for directing a web to and through the rotary 15 printing mechanisms, and means for operatmg the rotary mechanisms in unison with the bed and cylinder mechanisms, substantially as described.

In testimony that I claim the foregoing as 20 af'fix-my signature in presence of HENRY F. BECHMAN. In'presence of- GUY H. FENN, CHARLES A. GRAMES.
