Specification of Letters Patent.

Patented June 4, 1907.

Application filed August 27, 1906. Serial No. 332,169.

To all whom/it nuty 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 part of this specification.

This invention is an improvement in flat bed web printing presses of the duplex type, disclosed in the patent to Joseph Ir. Cox, No. 478,503, of July 5, 1892,, and the object of the present invention is to increase the capacity of such presses, and enable them to produce as many as sixteen newspaper pages at each operation.

The press contains four beds and four reciprocating impression cylinders and is so arranged that any even number of pages may be printed in this machine from two to sixteen. Inthis machine I employ two sets of equalizers or web-looping devices to handle the respective webs and two sets of feeding and delivery mechanisms. The feeding mechanisms are located at the opposite ends of the press adjacent to the rolls of paper, while the delivery mechanisms are both located near one end of the press and adjacent the folding mechanism. All the mechanisms are operated from one prime driving shaft and in unison, but two of the beds-and cylinders and their co-acting devices may be put out of operation when it is desired to print only eight pages or less.

The invention will be further explained in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a complete 16-page duplex press; Fig. 2 is a diagrammatical longitudinal section through such press, showing the web printing, feeding, looping and delivering mechanisms; Fig. 3 is a detail plan view of the delivery end of such press.

The press comprises four type beds 1, l, 2, 2, type beds 1, 2, being preferably in one plane, and type beds 1, 2 in one plane, but above and parallel with the beds 1 and 2. IVith the beds co-act reciprocating impression cylinders l 1 and 2 2 the cylinders 1 1, being mounted in cross-heads 3, slidably journaled upon the side frames of the press substantially as in the well known duplex machine, while the cylinders 2", 2 are journaled in similar cross-heads 3 mounted on the side frames of the press, in line with the cross-heads 3 and connected with the latter byrods 3 so that all the cylinders can be reciprocated simultaneously over their respective beds. The cross-heads 3 are connected by pitman rods 3 to crank gears 3, which are constructed substantially as in the duplex press, and when rotated impart reciprocatory movements to the cross-heads 3, 3 and the cylinders journaled therein. The beds 1, 1 are adapted to print one web, and the beds 2, 2' are adapted to print another, when producing sixteen pages in one color.

The web w, (which is printed on beds 1, 1 by cylinders 1", 1,) is led in from roll W under guides 4 and 4 to the feeding-in rolls 4 4, and thence passes over looping roller 4 down under fixed guide 4 to a guide 4 (traveling with the cylinder 1,) then between bed 1 and cylinder 1 up over a guide 4 (traveling with the cylinder 1*); thence under and over stationary guides 4* and l back over a guide 4 (traveling with cylinder 1) then between cylinder 1 and bed 1", up over a guide 4 (traveling with the cylinder l),thence to guide 4 down under looping roller 4", up to delivery rolls 4, where the web is divided, one half of the web passing direct to roller 4 at the head of a folder former F, while the other half of the web is turned over deflectors 4 and then led over guides 46 and to the former F, where it is assembled with the other half of the web.

The parts thus described are constructed to operate substantially as in the Cox patent, and the duplex press above referred to; the feeding rolls 4* and 4 being operated by gearing from the shaft 5, which operates a lever 5 carrying the frame 5 upon which the looping rollers 4 and 4 are mounted; and the delivery rollers 4 are driven in the same time as the feed rollers 1*, 1 by suitable gearing from the main shaft, as in the well known duplex press. The second web e0 is led in from roll W (at the end of the press'opposite roll W)under a guide 6 to the feeding rollers 6 6, up over looping roller 6, down to guide 6 over guide 6 (traveling with cylinder 2), thence between cylinder 2* and bed 2; and up over guide 6 (traveling with cylinder 2*), thence over guides 6 andv 6 to guide 6 (traveling with web w cylinder 2), then down between cylinder 2 and bed 2, and up over a guide 6 (travel ing with cylinder 2,) then back to guide 6 down under looping roller 6, then over guides 6 6 and 6 to delivery roller 6,which is above the delivery 4,at which point the is slitted and one half of said web passes to the folder over roller 6, and the other half is turned over the angle bars 6, (similar to the angle bars 4), and led thence under a roller 6 and up over roller 6 to the former F, being assembled at the former with the web w.

The feeding rollers 6 6 are driven by gearing from the shaft 7, which corresponds to shaft 5 and carries a cam which actuates a lever 7' operating the frames 7 upon which the looping rollers b and 6" are mounted, these parts being practically the same as the similar parts for operating the web w,-and the shaft 7 is driven from the shaft 5 by means of bevel gearing and shafting, as indicated in Fig. 1 of the drawings at 5 5 5 and 7 7 7 Z or in any other suitable manner.

The shaft 5 which transmits motion from the gears 5 to gears 7 may be formed in two sections connected. by a coupling memher 5", of any suitable construction, so that the right-hand feeding and looping mechanisms can be put out of operation when de sired, by .slipping said clutch out of engage ment with one section.

The delivery mechanism 6" may be driven at the same speed as the delivery mechan isms 4 by intergearing them, as indicated in Fig. 1 of the drawings at 6, or in any other suitable manner, the essential point being that the feeding and delivery mechanisms for both sections of the press must operate at the same time and to the same extent, so that both webs will be delivered to the former in proper time and position.

Each section (beds 1, 1 or 2, 2) of the press is adapted to print eight pages, using a full width web. If it is desired to print less than 16 pages, which is the full capacity of the press,a narrow width web may be printed on one section and wide web on the other, so that a ten, twelve or fourteen page paper can be produced. when eight pages or less are to be printed in one color, the right-hand secti on may if desired be put out of operation by disconnecting the clutch 5 and disconnecting the connecting rod 3 from the cross head 3. The described'press may also be used for multi-color work, that is to say, one web can be perfected in one color and additionally printed or perfected in multicolors also. For example, the web to after being printed on one side from bed 1, can be led across to and between bed 2 and cylinder 2 and printed in color thereon on the same side then led over guides 6 and 6 back between cylinder 2 and bed 2 to receive a perfecting impression in color, if de- 1 sired and then passed between bed 1 and cylinder 1, where it receives another perfecting impression in another color, and then passed on over roller 4 to the delivery, as indicated in the drawings. Similarly the Web 10 could be led through both sets of printing devices. If desired, in printing multi-color, the web w could be led through both looping mechanisms, but I consider this unnecessary. A web could also be perfected in one color, and have a colored impression applied on one side only by passing it between but three of the four sets of beds and cylinders; further- I more the one web could be led through the machine so as to be printed on one lower bed, say 1, and perfected on the bed 2 without receiving any color impression, as when it is not desired to print the web on any bed, it can be easily led directly across the cylinder of such bed instead of under such cylinder.

It will be obvious that the press can be threaded in various ways so as to print a web on one side only by but one of the beds or by two of the beds when coloring or perfecting a web.

By having the feeding mechanisms at the opposite ends of the press, the two sets of that the actual printing part of the complete machine is short, and it is practical to thread the Web through the several beds for multicolor printing as above suggested.

Having described my invention what I claim'as new and desire to secure by Letters Patent is 1.
