TOaliwhom it may concern:

Be it known that I, FnANcrs MmsnL, a i citizei'i of the United States, residing at Dovcr, in the countv of Stratiord. and State i of New l'lmnpshire, have invented a new and llSCfUl Pl'll1tlflg-l lt'SS, of which the. following is a specification.

This invention relates-to that class of rotnry printing presses which are designed to print'upon separate sheets.

The especial object of this invention to termittent, adjustable paper feeding mechmiisin for supplying the press with variable lengths oi sheets.

Fin-um objects and advantages oi the invention will appear hereinafter.

Reference is to .be had to the accompanying two sheets of drawings which show one form otthe invention, and in which,

Figure I isa plan view ofsufiicient )nrts of a printing press to illustrate the app iention of my invention. thereto. Fig. 2 is a sidei-t-hols'mne. Fig. 3 is n partial end View thereof, and Fig 4 is n; detail view of the deliverygrippers.

in producingthe coa-rsergrades of printing, and-even in producing some of the iiner )rintediproducts, a rotary printing ress may 'be operated at much higher speed t inn other styles of presses. This isdue t'o. thefact that the paper rims directly through the hinting only limited to the speed at which paper can be'.' fed rOn this account, rotary printing pressesnre now used for printing newspapers orfor other products which require longruns. In actunlipractice, however, the rotary prints, ing .presses have notes yet con "into general use for; ordinary job pr neg; or other purposes Where one, .pres. is; eduired to pi'oduee-nyarietly of products. l iis is due to theifacflthat rotniry printing presses as heretofore.constructed, have not usually been equipped to print on more than one size oi sheet, and the speed of rot-cry presses which have been, designed. to priut-sepm'ate sheets have been' 'limited to the speed at WhlGlitlie sepg at l cots-could be delivered from the n eehin moi-especial object of my present invention ist-to-provide a. rotary press which ma be readily setor.iidi'usted to produce ovum et'y of produ9ts.--,-,"o accomplish these reis severed into sl'ieets before being fed to the impression cylinder. mechanism is oi special construction, and although intermittent- .in action, it is controlledby two separate pawl and ratchet mechanisms, so :is to produce a substantially uniform. unwinding of the paper from the paperroll. he pawl and ratchet mechanisms are cup-ubleoi quick and simple adjustments .to produce any desired length of sheets, which sheets are severed from the web of paper. by the ordinary cutting cylinders, and are carried. by tapes to the impression cylinder onto which they lLl'G taken by grippers and are printed by passing between the impression cylinder and printing cylinder.

From the impression.cylinder the printed sheets are taken onto a giitl'iering cylinder which will forward successive sheets to the delivery, or which may be made to collect several successive sheets. In the present instance, the machine illustrated, is arranged to collect six sheets upon the gathering cylinder. 'lhese sheets then run ontoa reel rociiting carriage which moves forward at the same speed as the. paper-feed. The leading ends of the sheets are seized by-deliver grippers, which grippers hold the sheets 0 paper while the carriage is being moved'back into position to receive a succeeding number of sheets. The backward movement of the carriage takes place. at it much slower speed. than its forward motion. That is to say, the ea.r ridge is moved back from under the sheets at a slow even speed, so thatthe sheets will be The paper feeding' delivered smoothly and efficiently uponthe delivery table. I

Referring to the aceomnnying drawings for adetail description 0 a printing press embodying my invention, as shown in F1 1'-,

A designates the side 'fmn'ies. Journale at one end of the side frames A, as shown in jonrna-led iu '\-erticnlly movable boxes 14'.

Passing through the boxes 14 is a clamping shaft 15 having eccentrics for clamping the 1 upper feed-roll downin operative position, or-

for holding the same up when the uplift-ii ibeing threaded into place. From t e faeil are carried forward between cormtant-ly run rolls -12 and 13 the paper passes between the ning tapes '1, from which the sheets are taken by grippms (ion the impression (f' VllIHlltP'I. Cooperating with the inuression cylinderl is the printing cylinder 6 having the usual inking mecininisin, indicated by dotted lines. From the im )ression cylinder I the suceessiv eiy printed sheets are taken by grip iers G onto the gatl'iering cylinder B. \i en the desired number of sheets has been eollected on thegathering cylinder B, they are stiip )ed fliereirorn by the usual switeh S, which may be operated from the caIn-shaft of the 1n:-Is.chine by any ordinary ciqnneetions which need not be herein shown or described.

the sheets are stripped from t'he'gatherin; cylinder B they drop down onto .a. delivery carriage F which starts forward at the same speed as the travel of the sheets. The leading ends of the sheets are presented to the delivery gri ipels, (the construction and icration of which vwill be hereinafter de- .hcd) and the complete sheetshm'delii'ered upon the delivery table Z'When the delivery ige F is moved back into position to' receive a'sneceeding number of sheets. The gearing for operating these parts is most clearly illustrated in Fig. 1 of the drawin s.' As shown in this figure, the printing-cylin er ('1', impression-cylinder I, and gathering-cylinder B are geared to turn together. So cured on the shaft of the im )re'ssion cylinder l is a small pinion 27 whit: .meshes with a gear 28 secured on the cam-shaft 29. In the present instance, the gear 27 is onesixth of the size of the gear 28, so that the cam-shaft will he turned once'for each sixrevplution's' of the impression cylinder, or the cam-shaft 29 will make one'turn during the printing of six succeeding sheets. Meshing with and driven from the gear which is secured on the shaft of the gathering cylinder B is a pinion 18 journaled on a stud secured-in the side'- frames. Mounted upon .andturning with the gear 18 is a-slotted arm 19;;- 'Adjusta'hly fastened in the slotted arm 19 is a crank-pin 21 which is connected by a link 22 to a crossthe movable cr !SS hefld, and that the ways on the frame of the machine.- Pivoted on a crankin in the movable cross-head are 50 links23 an 24 which are connected'at their outer ends topawlwarrying arms having 7 ,paw'lsengagmg the ratchet-disk 25 secured upon the shaft. of the feed-roll 12.

By :ineans. of'this construction it will be seen that the (Tank-pin 21 will reci )rocate links 23 and 24 will swing the pawl-carrying arms inrelatively opposite directions. That is to say, these pawl-carryingarms will open and" shut iike the jaws ofnpair of scissors, so that whil'c onespawl-rnrrymg arm. is moving in' such direction as toadvanee the ratchet-disk its idle "or return strolic. I 1 consider this afeature-of lli'ljiml tllcifi, tLS by means of this novahle thereon, is a clutch-piece {10; whi is arranged to be'thrown into frictional A gagei'nen t either with the'largegear 36hr.

To 7 adjust this paper feeding" i'ncchanisin to produce dill'ercnt lengths of sheets, the crankpin 21 may he set or adjusted. to have dill'er ent lengths ol throw to move the cross head different distances as required. 1n some cases, in order to obtain a still finer adjustment of the length of sheet it is desirable to adjust one pawl-carrying arm independently of the other, so that its throw may be increased or decreased by one tooth of the ratchet wheel 'lo aecomplishthis lpurpose, the pin 26 which connects the lin with one of the pawl-carrying arms may be made eccentric, so that by setting or tul'ning I this eccentric iin, Ins fine an adjustment-as 35' required may he secured.

At their lower ends, the arms 44 are provided with a cross-bar 45 carrying the stationary'gripper jaw Journaled in the lower ends 0 the arms is a rock shaft-46 carr ing the movable gri pen-jaw 47. Exten ing from the rock-sh t 46 is an arm having a friction wheel which-is operated by a sliding cam 48. The swinging arms 44 are operated by a link from a lever 58 having a roller engaging a cam 49 on the cam-shaft 29, as shown most elearly'in Fig. 1, while the sliding cam 48 for elosin the movable gri per-jaw is operated by a k from a lever aving a friction roll operated by a cam 50 on the cam-shaft 29, as a so shown most plainly in Fig. 1. The delivery grip ers are normally 0 ened by 5 rings in t e ordinary manner. he parts 0? this deliver gripper mechanism are so timed that as t e sheets are being carried forward b the delivery table, the delivery grippers wi 1 meet the leading edges of the sheets, and will engage the sheets and hold the same While the delivery carriage is being retracted. The 'ppers wil then open and be moved sli ht y back so that the ends of the sheets wi drop down onto the table.

The operation of the several iarts of a printing press constr eted aceor ing to my invention have been fully explained in describin the constructions in detail, that it is not be leved necessary to describe the opera tion of the printing press as a Whole.

Although I have disclosed a delivery mechanism, I do not claim it herein.

I am aware that numerous changesmay be made in practicing my invention by those who are e illed in the art without departing from the see thereof as expressed in the claims, and t at my invention may be applied to printi presses of somewhat difl'erent ty 0 from at herein illustrated.v For exam e, my improved form of paper-feeding eet delivery mechanism 18 equall a plicable to a perfecting press in whicli tlih sheets are printed upon both sides. I do not wish, therefore, to be limited to the particular construction I have herein shown and described, but

What I claim and desire to secure by Lettars Patent of the United States is: I. In a printing press, the combination of a printing con la, a paper feeding mechap ism, two sets 0 intermittently operatlng core nections acting successively to produce a sub"- 'stantially continuous paper feeding action, and means for adjusting the same to supply variable lengthsof sheets.

e 2. In a printing press, the combination of a printing couple, a paper feeding mechanism, and two sets of intermittently operating pawl and ratchetmechanisms acting successively to produce a substantially continuous paper fee ing action.

3. In a printing press, the combination of, a printing couple, a paper feeding mechanism, andan actuating mechanism therefory'' comprising a ratchet wheel and two oppositel moving crank -actuated levers carrying paw s acting successively on the ratchetwheel, to reduce a substantiall continuous paper fee ng action. I

4. In a printing press, the combination of a printing c'ouple,-a paper feeding mechanism, and operating connections therefor, com-.

prising a ratchet wheel, a pair of awl car mg levers pivoted concentricall with t e ratchet wheel, a crank-actuated cross-head, a link connectin each pawl-lever with the cross-head, said iinks being arranged on opposite sides of the center of the ratchetwheel, and means for adjusting the throw of the crank which operates the cross head to produce'a variable length of paper feed.

5. In a printing press, the combination of a printing couple, a paper feedilig mechanism, and actuating connections therefor, comprising a ratchet wheel, ,two pawlcarrymg arms pivoted concentrically therewith, a

crank-actuated cross-head, a'link connecting each arm with the cross-head, said links being arranged on op osite sides of .the center of the ratchet-whee means for adjusting the throw of the crank which actuates the crosshcad to vary the length of the paper feed, and

an adj ustable connection between one of the awl. carrying arms and its link to provide or finer adjustments of the paper flied.

In testimony whereof I have hereunto set my hand, in t witnesses.
