tachinents for Printing -.Presses, of which the following is a specification. This invention relates to an nnproved rollrenewing attachment for printing 'g'esses, suphp which a new roll of paper can j p ied to the press in place of the spent roll without stopping the press, by placing the new roll in posit1on,-then splicin the paper from the new roll to the web '0 the spent roll and then running in the new roll while y moving simultaneous the spent roll put of the way, and .repeatmgthls operation as many times as may be required, so as to permit the continuous and uninterrupted'running of the press and-save the time heretofore lost in stopping the press in placing the newroll in operative position therein.

'. For this purpose, the invention consists i of a rollmenewmg attachment for printin presses, which comprises two horizonta screwrspindles, two vertical screw-spindles, roll supporting-blocks reciprocated simultaneously by said screw-spindles, a powershaft driven from the press, a cluteh mechanism adapted to move'said shaft in one or the opposite direction, means for transmitting motion in one or the other direction to the horizontal and vertical screw-spindles, 85 and means for throwing the clutch-mechanism out of mesh with the power-shaft when the roll-spindles have arrived at the ends of their motions. i

The invention consists further in the ar- 40 rangement of a system of web-car ing tapes located below the paper-roll and apted to convey the paper to the press and. rmit the splicing of the web of the new no] on to the web of the spent roll. I The-invention consists further in the arrangaement of ii-serrated cutting-blade and mec anismfor oscillating the same at the proper time so as to cut off the web of the spent roll after the splicin of its web with t e web of the newroll has been accomplished.

Theinvention consists further of the coinbination of a V-sha ed guide-rail supported :10 ide of the ro uidi frame of the entrwith a 1:: en ey on the spindle of the new roll and intermediate mechanism between the spindle of the new real i and the brake-pulley for starting and controlling, the forward motion of the new roll;

scribed hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a plalnview of my improved rollrenewing attachment for printing presses, Fig. 2 is a side-elevation of the lower poi" of one side of the attachment, the upper part being broken away, Fig. 3 is a vertical ion-- gitn inal section on line 33, Fig. 1, Fig. 1} 1s a side-elevation of the attachment'showing the opposite side of the same, and Figs. 5 and 6' are, respectively, a detail vertical section on line 5-5, Fig. 6, and line (3-4), Fig. 5, showing the improved gear for startin and controlling the motion of the new r0 1. Fig. 7 is a detail of one of the spindle lifting brackets, with their tension springs.

Similar letters of reference indicate corresponding parts in the difi' erent figures of the drawing.

' Referring to the drawings, A represents the supporting main-frame of my improvei. roll -renewing attachment for printing presses, which is connected at one and with the supporti -frame of the rioting press with which t e attachment is to he 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 a intermedietely between their ends. In stiitabie hearings 1), mac ed to the side-frames a, are supported two hfirizontal screw-spindles D, one on each side frame, and in bearings b on the upright extensions 0 a pair of vertical screw-spindles D, one on each extension, as shown clearly in Figs. 1 and 3. The thread of one screw-spindle of each pair of screw- 100 spindles is arranged in opposite direction to that of the other screw-spindle. so that when motion is transmitted from a transverse power-shaft which is supported in suitable bearings Moi the side-frames a, by we intermediate transmitting bevel-gears g, g and q, to the horizontal pair of screw spindles and by bevel-gears g, g and I 7' to the vertical pair of screw-spindles I5,

hlooks B, whie are placed on theacrewspindles D, D, are moved eitherin oneor has not been invented by me, and I hereby the opposite direction. Parallel with the horizontal screw-spindles l) and the vertical screw-spindles D are supported on the side-frames a and extension-frames a. hori zontal and vertical gu de-rods E and E, along which the reciprocating-blocks B and B are guided by sleeves 0 and c. The bloc s B on the horizontal screw-spindles D are each provided with a vertical guidesocketf, in which a vertical bar f is guided, which bars serve for the purpose of preventing the spindle S of the new roll of paper P, that is placed in position on the outermost ends of the side-frames a, from rolling forward toward its operative position faster than permitted by the motion of the blocks B. The bars f are each provided with a pin j which ,projects into a horizontal guide-groove f in each side-frame a, said groove being arranged parallel with the screw-spindle D and guide-10d E and provided at the end adjacent to the seats a located at the connection of the horizontal side-frames a and upright extensions a with an incline f,so that the vertical bars 1' are lowered for permitting the spindle of the i new roll to pass over the bars f and take its {face on the mats a when the new roll has en moved forward into its operative posihon.

' The blocks B that are reciP by the vertical screw-spindles D are provided with horizontally-guided brackets B that extend M at r' ht angles to the blocks in a. direction para el with the side-frames a toward the rear-end of the supporting-frame A, said brackets being pro"). ed at their outer ends with inclined faces and in their upper surfaces with concave seats so as to form bearings for the spindle-pf the spent roll when the same is to be moved upwardlv on the blocks onthe vertical spindles D. he sideframes a are provided at their rear-ends with lifting-levers L having each an upwardly-projecting lug a, which serve to prevent the new roll of paper from rollin 05 the side-frames a after it has been place in position thereon. Whenever a new roll is to be placed into operative position in lace of the spent roll, power is transmitted oh: the shaft of the impression-cylinder of the press, or from any other shaft of the same, by intermediate motion-transmitting mechamsm to the shaft S, and from the same by the intermediate bevel-gears to the horizontal and vertical screw-spindles D, D, so as to produce the lifting of the spent roll P in a vertical direction and the gradual forward motion of the new roll P into the position before occupied by the spent! ll,tin.connection with the blocks 13 and brackets B and the blocks 13. The mech anism so far described for lifting the spent roll and moving the new roll into its place distinctly disclaim the same.

T/m 'vluuble cZutcIz-mccizaniam.For the purpose of transmitting motion in one or the opposite direction to the shaft S and for automatically interrupting the motion of the same, a double clutch-mechanism C is arranged at one end of the shaft S, as shown in Figs. land 2.; This clutch-mechanism consists of a movable double clutch-member U which is splined to the shaft S and located intermediately between two clutchnwmbers C G which are placed loosely on the shaft S. The clutch-members 0*, C are provided with sprocket-wheels and z" 30 which are connected by sprocket-chains 2' and 2' with sprockehwheels z" and a" turning loosely on stud-shafts i and 2'', which are supported on the a'djacentside-franies a, as shown in Fig. 1.

' wheels 2', 2' attached thereto, to which continuous rotary motion is in: arted from the shaft of the iinpression-cy inder or, other convenient shaft of the printing press- As' 99 soon as a new roll is to be moved into operative position, the movable double clutch-' member C is shifted by operating a handlelever k at the opposite side of the mainframe A and a shifting-mechanism into 5 mesh with the clutch-member C, so that forward motion is imparted by the horizontal screw-spindles D to the new roll. and simultaneously upward motion to the spent roll P until the former takes the place of 106. the-latter. The shifting-mechanism is composed'of a connectin -rod 1: which is piv= oted to the handle ever :i. and extended transvcrselv across the main-frame A to a crank-arm I1 which is located belbw'the clutch-mechanism C. The crank-arm h is keyed -to the lower end of an upright rockshaft h which is in' a sleeve-shaped bearing 7:. supported in brackets h. To the uppe 1 end of the rock-shaft It is attached a forked 140 lever h which engages a circumferential groove h of the double clutch-member C so as to produce the shifting of the same into mesh with the clutch-members 1' C3. A second crank-arm it extends a ij ght- 11: angles to the crank-arm h inward y into the side-frame a, as shown in Fig. 21, and into the path of a horizontalpush-piece It. which is attached to the traversing block B of the adjacent screw-spindle D, so that '120 when the block arrives at its inward. position together with the new roll of paper. the crank-arm It is pushed sidewise and thereby the movable clutch-member C shifted clntch mcinber C and returned into its median pbsition between the cl'ntclhmembers- C C. The rotary motion of the shaft 5 is thereby instantly interru tedand the motion c the screw-spindles D, blocks B,

The sprocket-wheels 2" 5 by the forked lever It out of mesh with the 125, I

' oeiving the spindle S of the next spent roll and the blocks B and their retaining-bars f I the spindle of the new roll. For this purpose the handle-lever l1. and the iittermediate crank-mechanism are again operated and the double clutch-member C shifted and placed in mesh with the clutch-member C7. Rotary motion is thereby immediately ftransmitted to the shaft S, but in a reverse direction from its formernnotion, so.th a't the motion of the screw-spindles is likewise reversed'and the blocks B moved in outward, and the blocks B with their brackets-- B in downward direction. When the in-. clined faces of the brackets arrive in con tagt with the spindle S of the roll P, they are slowly pressed back against the teiision of their springs whereby the brackets can pass the spmdle S and :issume a position below the same, as shown.- in Fig. 3, with'their -concave :eats bclowthe spindle S. so that it, is ready to be engaged and lifted liy-the brackets B on their next upward motion. By the descending mption of the brackets B a wedge-piece agwhieh is attached by a vertical arm m to the block B next adjacent to the clutch-mechanism, engages by itstapes'ing face the inner end of the crankarm It. and pushes it'si'dewise, but in a direetion opposite to its former motion, so that. the forked clutch-lever h moves the clutch-member (3 'It; of mesh with the clutch-member G and interrupts thereby again the motion of the shaft. S and of the screw-spindles D. D and the blocks B,- B.

55 turned slowly on their pivots until the spin- 1 It appears thnsthaq the starting of the motion of the shaft S'is accomplished by the setting of the clutch-mechanism by the at- :tendant who operates the hand-lever hi m'd 'the intermediate crank-mechanism, while the stopping of the shaft is automatically accomplished by the actionof the push-piece 11- and the wedge-piece :v.

The roll-liftin levers Lgare pivoted to the up r corners of the sidera'ine's a and prov: ed with a hook-shapedprojection I be-' low their pivots. The spindle of the new roll is placed into juxta osition to the levels L and then lifted onto t e projections of the same. The lower ends .of the levers L abutagainst stop-pins Z, the loves being held by gravity in position alongside of the sidermnes a when not in use. \Vhen the spindle of the new roll is placed in position on the hook-shaped projections 1-, both levers L are taken hold of at their lower ends and roll is moved over the side-frames a towar tion by gravity, the projecting lugs (1 pre venting the roll from rolling otl the sldeframes a. T be web-feeding tapes;--At the lower part of the supporting-frame of the attachment, below the roll of paper when the same is in operative position for feeding the web to the press, is arranged a set; of endless web-guidmg tapes t which are stretched by suitable my guide and tension-rolls "t, t, .t, t, and moved by a driving-roll t, to which rotary motion is imparteih at. the same speed as that required by the paper in the press; The guide-roll t is connected by pivot-links t with the lower part of the frame A. The guide-rolls t, t, servefor guidin the tapes 1nan upward direction toward t e impression-cyhnder I-of the press, while the guide roll it conducts the web '0; from the up er ends of the tapes to the impression-c lin er. The tapes are intended not only to eed the web or from the roll in a reliable and uniform manner to the press, but also for the u r use ofiab e splicing of the web 10 of the new roll to the web w of the spent roll before the new roll' is gradually moved forward into operative position and the latter in upward posi-' tion out of the way of the new roll. The

tapes also actas an automatic tension-device for the web while'itis fed to the press. For the purpose of making a splice the end of the web of the new'roll is cut oil transversely at right-angles to its central line, and a coating o paste applied to the upper surface of the same, the coated end being then dropped on the lowermost parts of'the tapes, as shown in dotted lines m Fig. 3, so that as the new\ the press. the end of the new web is moved a forward by .thflnpflsahtlfgradually, drawn ini'below the'guide-rolli"t"intoicontactwith the web of the spent roll so that thc end of the web of the new roll is pasted to the-web .5 '01 the spent roll by the pressure of the guideroll t and tapes t on the two webs and thereby the splicing of the web of the new roll to ,the Web-oi the spent roll accomplished inn reliable and e fi'ective mannen.

The oscillating tion of the serrated cutting-blade is linii l. by the shaft S at one side and a stop-pin in: at the other side, as shown in Fig. While the web of the spent roll is out oif, the block B continues its motion until the pin m on the longer rod m engages the diametrically opposite finger mi and imparts thereby an oscillating return motion to the cuttingblade, so that' the same-is returned into its former position, shown in full lines in Fig of the next roll and so on. The teeth of the cutting-blade m are arranged at a slight angle to the biade proper so that they pierce in a reliable manner the web of the s. ent roll and produce thereby the cutting off of the same immediately after the web of the new roll has been spliced to'the web of the spent roll.

The ln-akemiechanism consists of brakeshoes l which are. pivot d to the ends of liralze-levm's l" and applied to the upper and lower parts of the brake-pulley 1"; as shown in Fig. l. The ends of the brakelovers 1" are locked so as'to hold the brakesl'oes or. the brake-pulley P by an adjustable loekingalerice. which is connected with the shaft of the cutting-blade and actuated by the same. 4

Before the new roll can take the place of the spent roll, it is necessary to remove the brake-shoes P from the b1'akepulley P on the spindle of the spent roll. This is acride complished by means of a crank-arm tug of the lever P of the upper brake-shoe P. I

This lever P is provided near its outer end and at its underside with a projection u so that the point 11? cannot pass beyond the projection u. The 11 per hrake-shoe-P is provided atits opposite end with a curved arm a that is engaged by the brake-pulley. of the spent roll for moving the upper' brake-shoe and its lever out of the way during the upward motion of the spent roll. The levers P of the upper and lower brakeshoes P are fulcrumed to'the ends of anupri ht. supporting-piece P which is prowith an interiorly-threaded hub .P that is engaged by a threaded stud-shaft P, as shown in Figs. land 4. The studshaft P is supported in the side-frame a and pro-, I

vided with a hand-wheel P at its outer end, so' that by turning the stud-shaft in one or the opposite direction, the u right supporting-piece P will be moved 'shghtl outwardly or inwardly into alinement wit 1 the longitudinal axis of the guide and ake-rail. R and the brake-pulley 1 so as to roducethe lateral shifting of the new ro on the sideframes to bring the web into proper relative position to the impressioncyhnder; 1 a The lower brake-shoe P is provided with a curved arm a" which engages the forked upper end of the connecting-rail r of the inner standard B so that the rail 1" as well as the guide and brake-rail R follow the lateral adjustment of the supporting-piece I and hold the brake-mechanism in minement with the guide and brake-rail and adjust the brake-pulley and the roll of apex laterally, as required. By the hinged and laterally-oscillating standards of the guide and brake-rail R the new roll of aperis shifted and its brake-pulley laced 1n alinement with the brake-shoes by the adjustment of the brake-levers I" described, so as to fully control the position of the-new roll relatively to the impressiomcylinder'and of the brake-pulley P to the guide and brake rail R and the br-alte-mechanism. On the brake-shoes P are arranged hi u, which project over the brake-levers and serve to hold them steadily thereon during. their release from the brake-pulley ofthe spent roll and their return into engagement with the brake-pulley of the new roll.

As soon as the cutting-blade isoscillated for cutting off the web of the spent roll and the elbow-lever n 1/. dropped out of enagement with the end of the upper brakeever P in the direction of the arrow, shown in Fig. 4, the elbow-lever is supported in tilted osition' at the outer end 0 the lower brakeever P. The upper brake-le er P and its brake-shoe Pfcan then be readily moved out of the way of the brakepulley on the spindle of the spent roll during the upward mot-ion of the latter until the brakelever assumes a vertical position by the contact of its brake-shoe with the brake-pulley of the spent roll.

The blocks B and brackets B are moved on the vertical screw-spindles l' for a sufficient distance below. the spindle of the spent roll that the release of the brakemechanism from the brake-pulley of the spent roll is accomplished before the brackets rengage the spindle of the for moving it out of the way. 'As will be seen by .the dotted line construction in Fig. 2 '3, the brackets B normally rest a short distance below spindle S". As during the upward motion of the spent roll, the new roll with its brake-pulley is moved into the former position of the spent roll. the upper brake-shoe drops by gravity on to the hrakcpulley of the new roll. as soon as its curved arm 'uis released from the brake-pulley of the spent roll; the attendant then returns the locking elhowdwcr 1/". u" of the brake.- levers P into position so as to support the upper brake-lever I" and apply both brakeshoes to the brake-pulley for exerting the required brake-action on the spindle of the roll and hold the some in position for permitting the new roll of paper to turn freely thereon while its web is fed to the printing press. The shifting of the new roll of paper by the proper alinement of the brake-pulley witli the guide and brake-rail and by the adjustment of the brake-levers, permits the free forward -motion of the paper-roll into operative position, while the action of the brake-shoes on the brake-pulley of the spindle as soon as the brake-levers are rclocked in position. permits the turning of the spindle and roll on the same against the friction of the brake-shoes for f eding the web to the rinting press. The brake-shoes, thev brake overs and the locking-device'for the latter have beenused in web-printing pres es before and form no part of my invention.

Operation.-Whcn the printing press is to be started, it is necessary to' return the blocks B and B on the horizontal and vertical screw-spindles D and D,one into their outermost. position on the horizontal screwspindles and the other in position at the lower ends of the vertical screw-spindles.

For this pur ose the hand-lever it. is moved by the atten ant for a sufiicient distance to spent roll 5 ported by the same; The blocks B on e horizontal screw-spindles are therebv moved to the outer ends of the same, while the blocks B on the vertical spindles are moved brackets B are located slightly below the angle-pieces at the connection of the hori 'zontal portions and vertical extensions of the side-frames. The new roll is then daced in osit-ion on the outer ends of the si e'frames )y the levers L. ward motion of the blocks B the wedgepiece .1: engages the crank-lever I! by which the movable clutch-member C is o wi'ated,

the clntch-mcmber C, and the motion transmittcd to the shaft S immediately interrnptcd. also the motion of the screw-s indies aml the blocks ll. B. The new to] being placed in position at the outer ends of the side-frames. its spindle rests against the projecting ends of retaining-bars f. The end til" the web of the new roll is then cut straight 5 across parallel to the axis of the roll and the tapes at the lower part of the mainframe. All is now ready for effecting the web of the spent roll. The press is then slowed down by the attendantuntil the web of the spent roll is run-down as close to its (-ore as desired. As soon as this mintis reached. the hand-lever 16- is moved in the opposite direction so as to cause the movable member C and start. thereby the motion of the shaft S. but in opposite direction to itq former motion. whereby moi ion is imparted to the screw-spindles andto the blocks on the same so that the latter are moved in an opposite motion to their former motion. Simultaneously with the starting of. the shaft S, the stafling-mechanism for the spindle of the new roll is actuated by the intcrmeshing of the rack p with the pinion that a turning motion is imparted to the spindle and the roll and the web of the new roll fed forward by the tapes at approxithe to es and the guide-roll t and pasted or l spliced starting-mechanism )rodnces the forward feed of the web and prevents the holding back or lagging of the same, so as to secure splicln" of the .wcb ot' the new roll to theclutch-member (7 to engage with the clutch-- is and the mechanism in gear therewith, so"

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 thatwhen 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 of the new roll fed to' the press in the regular manner.' The starting and forward motion of the new roll is' controlled by the blocks B and bythe guide and brake-rail until the brake-piilley onthe spindle of the spentroll is released from the brake-shoes and the latter are a lied to'the brake-pulley of the new to l. Vhen the new roll arrives in operative position,-the pusher-rod on the block B engages the operating crank-arm of the crank-lever of the movable clutch-member C and moves the some out of mesh with the clutch-memher C, so that the motion transmitted to the shaft S is interrupted and the motion of the screw-spindles and blocks instantly arrested.

The advantages of my improved roll-rencwing"attachment for printing presses are that. sinniltaneously with the forward motion of the new roll and the moving out of .lhe way of the spent roll, the splicin of D the web of the new roll to the web of the spent roll and-the cutting oil of the web of the spent roll are accomplished in a reliable and effective manner by the tapes arranged at the lower art of the attachment and by the action o the oscillating cutting-blade without stopping the press; while simultaneouslythe forward motion of the new roll into operative position is acrom )lished in connection with the starting-nice ianism applied to the spindle of the new roll and the guide and brake. rail until the new roll arrives in operatii'e position, when the brake-pulley on llI-L spindle; is engaged by the lll'ttliP-llltClltllllSlll, so'thal'the new rol with its spindle can freely turn on the spindlc for permitting its webto be fed to the printing press. 'l he different operations are accomplished in a reliable manner and require only the manipulation of the handlcvcr for starting the motion of the shaft S and the intermediate transmitting-mechanism, and the return of the locking-device for applying the brnke-mechanisni to the brakepulley on the spindle of the new roll. the renmining operation of arresting the'inotion of the'screw-s nndlcs and blocks, 'startm the new roll, sp icing the web of the new ro l to the web of the spent roll, cutting 05 the web of the latter. and releasing the brakeshoes from the brake-pulley of the spent roll. being accomplished automatically by the mechanisms hcreinhcfore described.

Having thus described my invention,
