REWINDING AND INSERTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 680,111, dated August 6, 1901. Applicatioii filed December 4, 1899. Serial lilo. 739,171. (No model.)

To (tZl whont it may concern:

Be it known that I, HENRY F. BEOHMAN, of Battlecreek, in the county of Calhoun and State of Michigan, have invented certain new 5 and useful Improvements in Rewinding and Inserting Mechanism; 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 stationary-bed reciprocating-cylinder type-printing web-perfecting presses of the type shown in United States Patent No. 478,503, of July 5, 1892, and commonly known as the Cox duplex presses. The larger presses of this type can only print papers of, at most, eight pages; and it is the object of this invention to enable a publisher to print and deliver from an ordinary duplex machine (whose maximum capacity, as stated, is eight pages) ten, twelve, fourteen, or sixteen pages, which may be cut, folded, and delivered as one paper. In brief, by this invention the size of the paper delivered from the press can be actually doubled, although the time required to produce the papers will be proportionately increased.

Many publishers of daily papers find it frequentl'ynecessary to print issues of more than eight pages, and heretofore in order to do this with an eight-page duplex machine ithas been necessary either to run two or more sections of the paper separately and deliver them to the subscribers in separate sections, which is very objectionable, or else to discard the old machine and purchase one capable of printing and folding at one operation more than eight pages.

In order to produce papers of extra size or from ten to sixteen pages on an ordinary duplex press, I first print, say, eight pages of the paper on an endless web of paper and without severing these papers from the web automatically rewind the same as printed upon a spool by suitable rewinding mechanism connected with the machine and then subsequently print the other sheets or portions of the paper upon another web and lead the previously-printed web from the spool on which it was rewound into the folding mechanism simultaneously and together with the second web as the latter is being printed and pass the said webs together to and through the cutting, folding, and delivering mechanisms of the machine, whereby all the pages tions.

The operation of printing and rewinding the first section of the paper, While involving some extra time and labor, will really not be a serious matter, as most of the papers printed on such presses do not have a circulation exceeding four thousand to six thousand, and the section of the paper to be rewound can thus be run through the press and printed in about an hour at very little expense, while the saving in the original cost of a machine capable of printing sixteen pages and the room occupied by it and in the expense of operating it will more than offset the loss of time.

The invention consists in the novel constructions and combinations of parts hereinafter claimed, and described with reference to the accompanying drawings, in which-- Figure 1 is a diagrammatic sectional elevation of a Cox duplex press with my improved rewinding and inserting mechanism applied thereto. Fig. 2 is an enlarged View of the rewinding and inserting mechanism detached; Fig. 3 is a detail section of the mechanism for driving the rewinding spool shaft. Fig. 4 is a detail view illustrating the rewinding and inserting mechanisms in a difierent location in the press. Fig. 5 is a detail View of the folder.

Referring to said drawings, K K designate the infeed rolls and tapes; Z Z, the movable web-looping rollers; M M m m, the station ary web-guiding rollers on the frame of the press; h h, the lower and upper type-beds; H'H, the lower and upper cylinder cooperating with the type-beds; fand f, the movable web-guide rollers beside the cylinders, and W designates the web of paper. These parts are constructed and operated substantially as described in the patent to Cox, No. 478,503, aforesaid, and need not be more particularly described herein, the same being well understood. After passing the upper looping-roller Z the web is led through a continuously-operating delivery mechanism, which is similar to the iufeed mechanism,

but driven slightly faster than the latter, and, as shown, is composed of the rolls A B and ism, which maybe arranged either above the folding and delivery mechanisms, as shown in Fig. l, or below and intermediate the delivery and folding mechanisms, as indicated in Fig. 4:.

Referring to Fig. 1, F and Gare rolls around which the web of paper is carried from the roll A to the spool J when rewinding same. W is the web of paper rewound upon the spool J. A, B, O, and D are rolls and E tapes for again feeding the web W of paper from the rewound roll to a guide-roller F, at which point it is brought into register with the new web W of paper being printed in the press and delivered through the deliveryrolls A and B. a Ct 11 b d d are gears upon the rolls A A B B D D and serve to keep the various rolls moving at the proper peripheral velocity. The gearj is loosely mounted on gudgeon J of rewinding-spool J. L and L are friction-disks secured to the gudgeon J by keys and are made to press against the faces of gear j by means of the nut L, threaded on the gudgeon J. The gear j is driven by gears 7i; and 7a, the latter being secured to the roll A. The gear j has a tendency to turn the spool J at a greater rate than the web is delivered to it; but as the spool Jdur- 'ing rewinding is caused to turn by the friction between thegear j and disks L L rupture of the web is prevented by properly adjusting nut L.

In a Cox duplex press the delivery-rolls A and B are slightly larger in diameter than the rolls feeding the paper into the press. This feature may be retained in the present instance; but the roll A is preferably made of the same diameter as the feed-rolls in order that as nearly as possible equal lengths of paper may be fed into the pressby the feedrolls K and from the rewound roll by roll A and tapes E. Of course previous to unwinding the printed web from the spool J the friction-disks L L are loosened, so as to permit the roll A and tapes E to draw the web therefrom.

The webs W and W pass on from the roll F to the folder; but for the purpose of obtaining easy register of the margins on the webs web W is looped over an adjustable roller N, between stationary rollers F and O, as shown.

and are handled as one.

The roll Nis for the purpose of adjusting the web W so that the margins ofthe sheets will coincide with the margins of the web W. Sprocket Q is driven by gears n-and a from gear a. The pointers P are secured to the chain R at equidistant points, the distance between any two points being the length of one sheet, of paper. The chain R is also caused to move at an exact speed with the web W.

The margins on web W are indicated by pointers P P on a sprocket-chain R, which is supported on sprockets Q and S. This enables theoperator to locate the margins on web W by pointers P, and by adjusting the roll N, thereby lengthening or shortening the loop of web W between the rollers F and O, and cause the margins on web W to coincide with the pointers P, and consequently with the margins on web W. After the two webs are associated they pass to the folder V, composed of the ordinary angle-plate of the cowcatcher type, having a pair of folding-rolls V at its apex, so that the associated webs are given a first fold before they are severed into sheets. They are then passed-through. the cutting-cylinders Z Z, by which the webs are severed. The webs may pass under a guideroller V between the rolls V and the cutting-cylinders, if desired; but it is desirable not to sever the webs until they are associated and given this first fold.

Operation: If it is desired to produce an extra-la rge papersay a sixteen-page paper on a duplex press, .which as ordinarily constructed is only capable of printing eight pages, the operation is as follows: The forms for eight pages (the full capacity of the press) are placed in the press, these forms being selected from those pages which do not contain the latest matter for publication. The press is then operated to print the web, as usual, with the exception that instead of the web being led on from the delivery-roll A to the folder it is switched off around the rolls F and G and rewound'upon the spool J until the desired number of impressions have been made upon the web and-rew0und upon the spool J. The forms are'then removed from the press and replaced by the remaining typeforms for the other pages of the paper, and the web is then broken and led from the deliveryroil A directly to the folder V, as indicated by the web W, and at the same time the end of the previously printed and rewound web W is led from the spool J (the friction-disks L L being previously loosened) to and between the feeding-roll A and tapes B, under the rolls F and F, looped over the roller N, and passed thence under the roller 0, at which point it is finally associated with the web W and passes'therewith over roller '1: to the folder V, where they are given the first fold and thereafter are cut into sheets, so that from the roller 0 onward the Webs W W pass Consequently a sixteen-page paper can be folded, cut, and delivered'as one instead of being delivered in sections. \V-hile this operation of course requires running double the length of time which would be required if the press were capable of printing thesixteen pages simultaneously, yet the time necessary for this operation is not great and the first eight pages can be printed while the forms for the other pages are being made up; The users of these. presses generally would have no serious objection to'printing a part of the paper an hour or two before the rest is printed, and the large saving in the cost of the press would more than compensate for the extra time required, and a press of this kind would be generally preferred on account of its smaller size, greater simplicity, and less cost. in oflices where extra-sized papers are only needed occasionally.

In Fig. at I have indicated an arrangement of the rewinding and inserting mechanism below and intermediate the delivery and folding The construction and opera-,
