To (Ill trimm iii-Nifty mun-er.

Be it known that l J nms 'l. Pn'ro. a eitizen of the United States residing at Ya te1'- son. county ot lassaie. and State of New Jersey. "Formerly a resident otNew York. in -theborough of Brooklyn, State ojt hen Yorlghare invented certain new and useful Tinpro-Yen'ients in Roll-Renewing Attach 'me'nts for 'Frinting-l. resses, of Whi'eh the toli out of the riayi and repeating. this opera tion as main. times as may he iii-(wired. so as to permit the continuous and uninterrupt d running of.. the press and save the time heretofore lost in. stopping; the press in placing. the. new roll in operative. position therein.

For this purpose. the invention consists of a .roll-reiiewing attachment for printing presse: which comprises two horizontal screwspindles. two Vertical serewspindles roll supporting-hloeks reciproeated sinndtaneonslv by said screw-spindles, a-powershaft, driven from the press, a clutch-mechanisni adapted to more said sha-i t in one or the opposite diretztioin means for transmit;- ting' motion in one or the other direct-ion to the. horizontal and vertical screw-spindles, and means for throwing the ehitehaneehanism out of niesh with the power-shalt when the roll-spindles ha vearrived at the ends of their'inotions.

The, invention eonsists further in the arrangement oi? a system ot Wehmarrying tapes loeated below the paper-roll and adapted to convey the paper to the press and permit the spiieing oi the Web of the new roll on to the web of the si ient roll.

The invention consists further in the arrangement ot a serrated cutting-blade. and mmihanism tor oscillating the same at the proper time so as to out otf the weh of the spent roll after the splicing of its weh with the web of the; new roll has been aeeonr plished.

The invention consists further of the cornhinat'ionot. a V-shaped guide-rail supported alongside of the roll-gnidin frame of the att: rlnnent with a brakeqndiiry on the spindle of the new roll and intermediate niechanisrn between the spindie of the new roll and the hrahe'rmlley for starting and controlling; the forward motion of the new roll; and the invention eonsists lastly of certain additional details ot construction and cornhination of parts which n'il be fully described hm'eina't'ter, and finaily pointed out in the claims.

Referring to the drawings. A represents the supporting inain- Frame of my improved roll -1renewing attachment for printing presses, Whieh is connected at one end with the snpporting-franle of the printing press with which the. attachment is to be used. The frame A is composed of two upright side-frames a, which are connected by trans verse brace-rods and which are provided with upright, extensions (1 intermediately between their ends. attached to the side-frames a, are supported two horizontal sere\v-s .iindles I), one on each side-frame; and in bearings 71 on the upright extensions 0 a. pair of vertical screwspindles D, one oneach extension, as shown clearly in Figs. 1 and The thread of one sc e\\"--s indle ot each pair of srarerrspindies is arranged in opposite direction to that of the other sertm spindle. so that, when motion is transmitted from a transverse powershaft S, which is supported in suitable In suitable hearings Z),

dles D, D are moved either in one or the the sidet'rnmes a, from rolling jwsedrits operative position faster than per so that the vertical bars f permitting the spindle of dle moved forward into its prevent the new roll of paper from opposite irection.

The hers f are each provided with a pin f which projects into a horizontal guide groove 7? in each sideimine a,- said being arranged parallel with the screwspindle D and guide-rod E and provided at the end edjac'entto the seats (1, located at the connection of the horizontal side-framesa and upright extensions a with an incline f, are lowered for the new rollto pass over the the seats a when the new roll has been operative position. The blocks B that are reciproceted by the vertical screw spindles I) are provided with horizontally-guided brackets B that extend at right-angles to the blocks in a. direction parallel with the side-frernes a, toward the rear-end of the supporting-frame A, said brackets being provided at their outer ends with hiclined feces and in their upper surfaces with concave seats so. as to form bearings for the spindle of the spent roll when the some is to be moved. upwardlv on the blocks on. the vertical spindles D The side-frames a ere provided at their renrends with lifting-levers L havin each an upwardly-projecting lug a, whic serve to rollingofi' the side-frames a giter it has been placed in position thereon. Whenever a newroll is to be placed into operative position in place of the spent roll, power is transmitted same by the intermediate from the shaft of the impression-cylinder of the press, or from any other shaft of the ,same, by intermediate n'iotion-transmitting mechanism to the shaft S; and from the horizontal and vertical screw-spindles 1), D

The double cZutck-mecfiam'sm.-For the purpose of transmitting in 0116 01 site direction to the shaft S and for ontomaticslly interrupting the motion of the some; it double clutch-mechanism C is arthe shaft S, as shown in Figs. 1 and 2. This clutchmechcnisrn consists of a. movable double clutch-member U which is spliced to the shaft S and located intermedintel y' between two clutchmemhers- C G which are placed loosely on the shaft S The clutch-members 0 G are provided with sprocket-whcels i and 2' which are connected by sproch'etrhains i and .5 with sprocket-wheels '1? and i turninglnosely on stud-shafts i and 27'', which are supported on the adjacent sidefremes a, The sprocket-wheels i and i are provided respectively, with the oppo gear-wheels i 7? attached thereto to which eontinnous rotary motion is impart-ed from the shaft of the impression-cylinderor other printing press As soon as a new roll is to be moved into 010- erstive position, the movable double clntchmember C is shifted by operating a handle lever 71, at the opposite side of the main frame A and a shifting-mechanism into mesh with the clutch-member so that forward motion is imparted by the h0I'iZoI1 tal screw-spindles 1) to the new roll and simultaneously upward motion to the spentroll P until the former takes th ace of the latter. The shifting-mechan: posed of a connecting-rod 72 which. is pivoted to the handle-lever it and extended transversely across the main-frame A to s,

cronies-rm 71 which is located below the clutch-mechanism C. The cronkerrn fi 'is keyed to the lower end of an upright rocksheft k which. is in e sleeve'shaped hearing it supported in brackets it, Tattle-upper end of the rock-shaft k is attached a forked lever it which on ages a circumferential groove (72,7 of the dou 1e clutch-n1ember C so as to produce the shifting of the same into mesh with the clutch-me1nhers G or 0 second crank-arm h? extends at right-angles to the crank-firm h inwardly into the side frame a, as shown in Fig. 1, and into the path of a, horizontal pusl1-piece h", which is attached to the traversing block B ofthe adjacent screw-spindle D, so that when the block arrives at its inward position together with the new roll of paper, the crank-arm I68 is pushed sideWi-se and-thereby the movable clutch-member C shifted by the forked lever it out of mesh with the clutch-member B'-, a. wedge-piece 0?, which C and returned into its median position between the clutch-members C C tary motion of the shaft 'S is thereby in-- stantly interrupted and the motion of the screwspindles l), D blocks 13,13 and the rolls P, P arrested. lhe spent roll P is then removed from its brackets B The blocks I and their brackets B have then to be returned from their raised position into a position below the spindle of the new roll and the blocks B from their inner-most position into their outermost position, so that the brackets B are ready for receiving the spindle S of the next spent roll and the blocks B and their retainingbars ,t" the spindle of the new roll. For this purpose the handle-lever h and the intermediate eranlemechanism are again operated and the double clutch-member C shifted and pga ced in mesh ,gwith the clutch-member C otar motion is thereby immediately transmitte to the shaft S, but in a reverse direction from its former motion, so that. the

motion of the screw'spindles is likewise rcbrackets B on their next upward motion.

By the descending motion of the brackets is attached by a vertical arm 11: to the block 13 next adjacent. to the clutch-nierlainisin, engages by its tapering face the inner end of the crankarrn it and pushes it sidcwisc, but in a direction opposite to its former motion, so that the forked clutch-lever it. moves the clutchmeinbcr C out of wash with the clut h member and interrupts thereby again the motion of the shaft S and of the screwspindles l), l) and the blocks B, B It appears thus that the starting of the motion of the shaft S is :urromplished by the setting of the clutch-mechanisin by the attendant who operates the hand-lever h and the intermediate crank-nic -hanisni, while the stopping oi the shaft 'is 'auton'latically' accomplished by the action'o't' the push-piece It and the wedge-piece .r.

The rolllii'ting levers ll are pivoted to the upper corners of lbe side-frames a and provided with a l)( ()l bl]|(!(l projection 15 below their pirots. The spindle of the new roll is placed into jii.\'l:iposit ion to the levers It and then litled onto the projections of the same. The lower ends of the lcversii abut against stoppins Z, the lovers being held by gravity in position alongside of the The to side-frames (I when not in use. \l'hcu the spindle of the new roll is placed in position on the hook-shaped ])l0j(('ti4)l1s 7. both levers L are taken hold of at their lower ends and turned slowly on their pivots until the spindle of the roll moves by gravity over the lugs at the ends of the levers L onto the corners of the side-frames a and against the projecting ends of the retaining-bars f 'l'he levers are then lowered again in the position shown in Figs. 2 and 3, and held in this position by gravity, the projecting lugs (1 preventing the roll from rolling oil the sideframcs a.

, The web-feeding tapcs.i\t the lower part of the supporting-frame of the attachment, below the roll of paper when the same is in operative positinn fol-feeding the web to the press, is arranged a set of endless webguiding tapes If which are stretched by suit- 'able guide and tension rolls t, f, i t", and

moved by a dri\'ingroll t, towhii-h rotary motion is imparted at the same speed as thatrequired by the paper in the press. The guide-roll t connected by pivotdinlts L with the lower part of the l lillllt A. The guide-rolls i it, servedor guiding the tapes in an upward direction toward the illlprcssion-cylindcr l of the press, while the guideroll 15 conducts the web in from the upper ends of the tapes to the innncssion-rylindcr. The tapes are intended not only to feed the web "2/: from the roll in areliabl: and uniform manner to the press, but also for the reliable splicing of the web in of the new roll to the web to of the spent roll as the new roll is gradually moved forward into operative position and the latter in upward position out oi the way oi the new roll. For the purpose of making :1 splice the end of the web of the new roll cut ofi": transversely at righbangles to its central line, and a coating ot'paste applied to the upper surface of the same a short distance backat end, and then the end is taken hold of by the hands of the operators, one on either side of the apparatus, and inserted under the roller 1/. The new roll is held stationary and its end only permitted to pass under the roll i a short distance sutlicient to pull tbeweb taut, care being taken that the line of paste does not come in contact with the old web. The parts remain in this condition until the web on the old roll has about eZ\' --120 pirrd, when the clutch is thrown to pcrn'lit;

-tbe new roll to move for ard over the side-- frames. As the new roll thus moves forward, atthc same time being given a momentary positive rotary movement. to unwind its web, the new web is drawn between-the 'roller 6" and the tapes so that the pasted portion passes between them, thereby splicing the end of the new Web to the old web.

Werel e131 es :Essl: as the snide and brake-rail R see is provided at its inlad a spring-actuated pawl p which is pivoted to a gear-wheel p that is placed loosely on the roll-spindle. A pinion p is mounted loosely on a stud-shaft p at the upper end of the standard R below the ingoing end of the guide and brake-rail R, and placed in mesh with the gear-wheel 72 above and with a horizontal .rack 79 below, said rack being supported on a bracket n. that is attached to the block B adjacent to the guide and brake-rail R and extended at ri 'hbangles tosaid block through the side-frame a, as shown in Figs. 5 and G. The rack 32 is made of suflieient width to provide for the lateral oscillations of the guide and brake-rail R without being disengaged from the pinion hen forward motion is imparted to the block B by its horizontal screw-spindle D, the rack p transmits by pinion 72 gear wheel 72 pawl 79 and internal ratchet-gear p, rotary motion to the brake-pulley P and the spindle of the roll, so as to start the same while its spindle is held back by the retaining-bars f of the blocks B. The start-. ing motion of the roll is thus accomplished in an easy and steady manner, so as to permitthe free forward motion of the coated end of the web as it is fed by the tapes and roll t for the splicing operation until the rack 9 has passed out of mesh with the motion-transmitting pinion 'Wl'lBl']. the rotary motion of the roll is continued by the tension exerted (in the same by the spliced web asit is drawn in by the press and the slight inomentuln imparted to it by the startingmechanisin. \Vhile the new roll moves forward over the side-frames tr and the brake pulley P over the guide and brake-rail R, the spindle ot' the spent roll is lifted out ot the way of the new roll by the brackets P)" and blocks B operated, by the vertical spindles D iVhen the spindle ot the new roll arrives in the position before occupied by the spindle of the spent roll, the rotary notion of the screw-spindles is automatically interrupted by the double clutch-mechanism before described and the paper fed to the press from the new roll in the same manner as the web of the roll which was before in this position, as the splicing of the web of the new roll to the web otthe spent roll has been. accomplished in the meantime. i

The brake-Inerhanism. consists of brakeshoes I which are pivoted to the ends of brake-levers l and applied to the upper and lower parts of the brake-pulley l as shown in Fig. 4-. The ends of the brakelevers I are locked so as to hold the bra keshoes on the brake-pulley l by an adjustable locking-device, which is connected with the shaft of the cutting-blade andactuated by the same.

Betore the new roll can take the ear of the spent roll, it is necessary to remove the brai -shoes P from the brake-pulley P on laterally, as requ red.

tb e spindle of the spent roll. This is accomplished by nieans of a crank-arm M, which is attached to the opposite end of the shaft m and connected by a flexible rope or chain a with an elbow-lever u" that is fulcruined to the outer end of the lever l" of the lower bral e-shoe I. To the threaded upper arm n, of the elbowdever n is applied an interiorly-threaded sleeve 14", which is operated by means of a hand-wheel 14- said sleeve being provided with a point u at its upper end for engaging the outer right supportingpiece P which is provided with an interiorly-threaded hub P that is engaged by a tl'ireaded stud-shatt 1", as shown in Figs. 1 and (L. The studshatt l." is supported in the sidedranie a and provided with a handovheel P at its outer end, so that by turning the stud-sl'iait in one or the opposite direction, the upright supporting-piece P will be moved slightly outwardly or inwardly into alineuient with the longitudinal axis of the guide and b alierail R and the brakepulley P so to pro (lure the lateral shitting of the new roli on the side-frames to bring the web into proper relative position tothe iinpressioil-cylinder.

vents the holdingi' back or lagging of the same, so as to secure in a positive manner the splicing of the new roll on to the web of the spent roll. As soon as the splicing is accomplished, the separating-blade is oscillated and the web of the spent roll cut ofi, Simultaneously therewith the blocks on the horizontal spindles are moved forward with the-new roll and the blocks carrying the spent roll moved in upward direction, so that when the spent roll is lifted out of the way, the new roll arrives in the position before occupied by the spent roll and the web B engages the operating crank-arm of the cranlclevcr ot' the movable cluteh-nien'lber (1' and moves the sameout of mesh with the clutch-member C so that the motion transmitted to the shaft S is interrupted and'thc motion of the screwspindlcs and blocks inslantly arrested. i

The advantages of my improved roll-renewing attachment for printing presses are that. simultaneously with the forward m0 tion of the new roll and the moving out of the way of the spentroll, the splicing of the web of the new roll to the web of the spent roll and the cutting off of the web of the spent roll are accomplished in a reliable and ell'eetive manner by the tapes arranged at the lower part of the attachment and by the action oi the oscillating cutting-blarile without stopping the press; while simultaneously the forward motion of the new roll into operative position is accomplished in connection with the startingnnechanism applied to the spindle of the newroll and the guide and brake rail until the new roll arrives in .-perative position, when the brake-pulley on its spindle is engaged by the brake-inechanisnn so that the new roll with its spindle can freely turn on the spindle for permitting its web to be fed to the printing press. The difi'erent operations are accomplished in a reliable manner and require only the manipulat-ion 0f the hand-lever i'or starting the motion of the shaft S and the intermediate transmitting-mechanism after the end of the new web has been inserted by hand beneath the roller t, and the return of the lockingdovice for ap lying the brake-mechanism to the brake-pul'ey on the spindle-of the new roll, the remaining" operation of arresting the motion of the screw-spindles and blocks,

starting the new roll, splicing the web of the new roll to the web of the spent roll, cutting of! the web of the latter, and releasin the brake-shoes from the brake-pulley 0 the spent roll, being accomplished automatically by the mechanisms hereinbefore described.

Having thus described my invention, 1 claim as new and desire to secure by Let-- ters 'l'atent:
