Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed October 5. 1907. $erial No. 396.100.

To all whom it may concern:

Be it known that I, PAUL FLEMMING Cox, of Jackson, in the county of Jackson 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 drawpapers of four, eight or twelve pages, from a single web, and by the use of two webs, as hereinafter explained, it is capacitated to produce papers having six or ten pages.

The present invention, therefore, consists in means whereby a narrow web may be fed through the press and printed thereby, such narrow web being threaded in a different way and handled in a different manner from the wide web.

The invention will be clearly understood from the following description in connection with the accompanying drawings, and the parts and combination of parts for which protection is desired will be set forth in the claims.

' in the main frame A, and one of the gears meshing with a pinion h on a driving shaft H Above each bed is located a pair of cylinders I, I which are respectively adapted to 0perate with forms C, C on the outward print-.

ing strokes of the beds. The cylinders may I be mounted in eccentric boxes X, which are connected to bars W, the latter being pivoted to one end of a lever V, which is pivoted on the frame and is connected by a rod U, to a lever T, pivoted on the frame and carrying a roller t, engaging a race cam S, on one of the gear wheels G or its shaft. By this means the bearings X will be oscillated at the proper time throwing the cylinders on or 0H impression.

N, is the web feed roll, and P, the delivery roll. These rolls are preferably intergeared by a train of gears p so as to move atthe same peripheral speed. With the roll N coacts a series of tapes-Q, running over. rollers n; and with roll P, co-acts a series of tapes R, running over a series of rollers r.

Customarily the main web M is led in from a roll J at one end of the machine, to the feed roll N, thence passes over a guide O, between cylinder I and bed B, at the left of the machine, over guide 0, 0 then down between left-hand cylinder I and bed B, then up over guide 0 back over guide 0 down between right-hand cylinder I and bed B, and up over guide 0 0, down between right-hand cylinder I and bed B, then up over guide 0 to the delivery P. i

As described in my said patent, the cylin- U ders I, I, print simultaneously on the web, but on different. portions thereof, being arranged in this manner so as to shorten the travel of the beds. -..Thus, although each bed B only travels. sayseventeen and onehalf inches, (less margins), during impression, the

two cylinders I, I-, will print twice that much Web, or saythirtyfive inches of web during each printing stroke of the bed. To enable this to be done the web is so fed that the cylinder I, prints portions of the web,

skipped by cylinder I, and therefore, in order to enable this to be done, seventeen and onehalf inches of web, (less margins), must be fed during the taking of impressions, and the remainder seventeen and one-half inches of web, (plus margins), must be fed after im presslons, or during the return strokes of thebed, while the cylinders are off impression.

As the beds are operated in the present the crank movement of the bed.

scribed in my aforesaid patent. In the present instance I have illustrated irregular gears.

for operating thefeed r011. Nat a peripheral speed conformable to the crank movement of.

instance by a crank movement it is necessary S U that the web be fed, during the taking of impressions, at a, variable speed uniform withv This maybe accomplished in various ways as deas to feed the desired amount of web during I ion application for continuous variable web feeding mechanism, filed October 4, 1907, Serial No. 395,944, and therefore is not claimed specifically herein.

As shown, an irregular gearY is fast to the roll N, and meshes witha similar irregu lar gear Z, fast on the shaft G, or one of the adjacent crank gears G. The gears Y, Z, are of such outline that they will cause the periphery of roll N to move in exact uniformity with the travel of the beds'B during the actual taking of impressions, and thus to feed the necessary amount of webwith the bed; and when the impression is thrown off, the gears Y, Z, will continue to operate the roll N, at such speed that during the remainder of its operation an additional similar length of-web may be fed between the beds and cylinders. .Thus the roll N can be operated continuously at a variable speed andv feed the web forward in the desired manner at all times, dispensing with the necessity of any looping or compensating rollers between i the feed and delivery mechanisms.

The delivery roll P, being geared to the roll N, can be driven at the same peripheral speed as the roll N, and will properly take care of the web fed/into the press.

When printing four, eight or twelve pages, a single web is used. If it is desired to print in such a press a six or ten pagepaper, a narrow or pup web to, is threaded through the press beside the other web M; the pup web being only a single page wide, while the web M is two or four pages wide. This pup web to as shown, is led in to roll N, then passes over roll .0, down between lefthand cylinderI and bed B, underand over roll O, then back directly to and over roll 0 then down between the right-hand cylinder I and ,bed B, then up" over the roll 0 being in this manner printed on one side by the lefthand bed and cylinder I, and being perfected on the other side by the right-hand cylinder I and bed B. I From roll '0 the pup web passes to the delivery.

' As shown, I provide an auxiliary delivery mechanism for this pupf web, located beside the'roll P, and comprising a roll 2, which is driven by gears 4 4*,from a gear 4, on shaft of roll P. These gears being such that roll '2, has about one-half the peripheral speed of roll P, as the pup web is only fed through the press during the printing operation.

' The pup web passes around roll N, but the tapes Q, which engage the pup web to should be slackened soas to only coax but not actually feed the pup web forward until the delivery begins-to pull on the web to and it is nipped between the forms on the beds and the impression cylinders I. As the pup delivery preferably acts continuously I provide means for looping the pup Web between roller 0 and its delivery roll 2. Thus i as shown, the web w after passing roller 0" may be led over a guide 3 then over a looping roller 3, then back under guide 2", to the roll 2, with which co-act tapes 2, which pass over roller 2 and guides 2 2.

The looping roller 3, may be operated so as to take up the pup webas it is fed for- 'ward during impression by means of a bar 3, to which roller 3 is attached, and which bar is provided with a roller 3', engaging a race cam 3 secured to the shaft of roll P. Said cam being so shaped that the moment before the beginning of an impression the roller 3 begins to take up a loop in web to and in conjunction with the pup delivery and the beds and cylinders, draws the web to forward over roll 0 as fast as it is printed. At the end of the printing operation, roller 3 is moved so that it gradually gives up this loop as demanded by the pup delivery roll 2. Thus the pup sheets can be delivered to the folder simultaneously with the main sheets.

The foregoing explanation and the drawings will impart a sufficiently clear understanding of the invention and itsmode of operati0n,but themeans for feeding and delivering the pup web may of course be varied; that shown herein being the present preferred mode of handling such web. It will be observed that the pup web to, does not follow the path of the web M, except as far as the roll O, then it separates from web M, and passes directly to roller 0 at which point it again meets web M,'and passes therewith as far as roll 0", where it again separates therefrom and passes direct to the delivery. Also the pup web to is printed by only one cylinder in each pair,

whereas the main web M passes successively between both cylinders in each pair and their bed. The pup web 10 therefore does not have to be fed after impressions, while the main web M must be fed after impressions.

Having described my invention what I desire to secure by Letters Patent is 2 1.
