Specification of Letters Patent.

Application filed Gctober 6, 1904. Serial No. 227,435.

To all whom it may concern:

Be it known that 1, Louis F. Pms'rnn, a citizen of the United States, and resident of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Means for Supplying and Feeding Paper to Printing- Presses, of which the following is a specification.

The present invention relates to that class of printing presses wherein the paper to be printed is in the form of a web drawn from a roll and fed through the machine, the webs of successive rolls assuming such connected relation, that the paper from a plurality of rolls will be fed to the printing machine in p a continuous web, without necessarily involving the stoppage of the press or the interruption of the printing operation.

The object of my invention comprises novel devices for adjusting a roll of paper in position, mechanism for removing the spindle or spindles of an -exhausted roll, said mechanism being coactive with said devices so that the removal operation will be contemporaneous with the adjustment of a succeeding roll, peculiarly constructed and disposed provision being employed for connecting the webs of the rolls, so that the paper therefore will be efliciently fed to the press in a continuous manner. 7 There are other important features and combinations of parts connected with the invention, which features and combinations as well as those previously alluded to, are clearly set forth in the subsequent detailed description. I

The accompanying drawings illustrate a portion of a printing press containing one embodiment of my invention, in which- Figure l is a vertical section representing a roll of paper bein represented in said figure as adjusted pre iminary to supersedin the spindle and core of an expiring r01. Fig. 2 is a side elevation of the portion of the frame viewed from a position opposite to that shown in Fig. 1, the renewal roll being in its full operative position, and the spindle and core of the exhausted roll being in an inoperative osition. Fig. 3 is a detail sectional plan of the parts illustrated in Fig. 1, the sectionbeing in the plane indicated by the broken line-3-3, of said figure. Fig. 4

is-a view similar to Fig, 3, but illustrating parts at the other side of the machine. Fig.

5 is a detail view, showing on an enlarged scale, one of the lifting brackets, its block and certain immediate features, the bracket and block being represented by full lines as near the limit of their downward movement, while dotted lines indicate said parts as hav' ing attained their lowest position.

Similar reference characters are employed to designate corresponding parts in the several figures of the drawings, where they occur.

In theembodimentof the invention disclosed herein, the rear standards A, of the frame of a printing press have the longitudinally disposed extensions B, B, the top parallel horizontal bars of which contain contiguous to the standard A, the uper open bearings b, for the reception 0 the end portions of the spihdle S carrying the roll of paper P.

b, b, are upper projections located at the outer ends of the top bars of the extension 1, of said shafts being keyed-ended for the application of a crank or other means to facilitate the rotation of the shafts by hand. The other end of the shaft is mounted in bearing 1, 1", secured on the inside of the frame. i

A block or traveler 7 and 7 w are mounted on the shaft 1 and 1 and have internal threadsengaging with those of said shafts so that the blocks will travel back or forth as the shafts are revolved in one direction or the other. Integral with this traveler is a short standard 7. At the upper part of the. standard are front and rear horizontal ears 7", 7, respectively. A bar 7, has one end pivotally connected to the ear 7", while at its other end it is provided with a lateral lug 7. Pivotally attached to the ear 7, is one end of a bar 7, to the other end of which is ivotally secured one end of a con necting link 7 having its free end 7 hookshaped to engage the lug 7*, of the bar 7, when both bars 7' 7, are swung to thever- Patented July 1%, 191%.

tical parallel position indicated most clearly in Fig. 1. Said bars carry on their inner vertical faces, friction shoes 7, which may be of yielding material and which are preferably recessed to adapt them for intimately bearing within the grooved periphery of an adj acently located pulley s, keyed on the roll-spindle S. The frictional pressure exerted by said shoes can be varied by making the link 7 of sections 7 7*, the former of which presents a threaded socket for the engagement of the threaded shank of the section 7 Manifestly, by revolving a nut 7 carried by the section 7 the rod 7 can be contracted or extended in length and result in an increase or diminution of the frictional pressure'exerted on the pulley s.

A rod 1', supported counter to the shaft 1, passes through the standard 7 and operates to retain the block 7 and standard from turning on said shaft, and a similar rod 1 passing through the block 7 prevents it from turning on its shaft 1.

In upper and lower bearings a, a, on the inner side of the standards A, of the frame, is journaled a vertical screw shaft 2, on which is mounted a traveler or block 13, internal threads of which engage those of the shaft so that the traveler will move upward or downward according to the direction of rotation of the said shaft. A vertical guide rod 2, suitably supported by the standard A, asses through and maintains the block 13 rom turning on the shaft 2. v

15 is a horizontal arm, supported by the block 13, so as to be movable longitudinally relative thereto, said arm being provided at its forward end with a bracket 14, having an upper depression or recess 14, to serve as a bearing for one of the end por-i tions of a roll-spindle. The other end of the roll spindle is carried by a corresponding arm 15. The outer edge 14:, of the bracket is inclined. The arm 15 is normally maintained in a projected position by means of a spring 15, indicated in Fig. 3, said spring being interposed between abutments of the traveler and arm. Miter gears 8 and 9, secured on the shafts 1 and 2, respectively, serve to transmit motion'to the latter from the revolution of the former.

One of the press-cylinders C, (see Figs. 2 and 3) has its shaft projecting at one side of the main frame, and to which is secured a gear 31, the revolution of which is caused by that of a gear 29 and an intermediate gear 30, said gear 29 forming part of the clutch mechanism on the transverse power shaft 12, the latter carrying a bevel gear 11, meshing with a gear 10 for simultaneously operating the screw- shafts 1 and 2.

29 is one member of a clutch secured to the gear 29, the latter being loosely mounted on the shaft 12.

34*, is the movable member of the clutch, the jaw of which member is adapted to be engaged with that carried by the wheel 29.

The movable member 3 L", adapted to be operated by a lever 33, the bifurcated or yoked end of which is suitably engaged with said member to slide the same upon the shaft 12. Small pins 35, 36 are rigidly carried by the movable part 34 of the clutch and engage with openings in a disk 31h so that they may playback and forth within the same, said disk being secured to and movable with said shaft 12.

The arrangement of pins 35, 36, enables motion to be transmitted to overcome the load required in starting the paper-roll supply means into actuation, the points of transmission presented by the pins being more evenly distributed than were connection more directly with the shaft 12. Consequently. there is less tendency of straining or wrenching the parts operated through the motion of the shaft 12.

Rigidly projecting from that side of tlie frame at which the lever 33, is located, is a horizontally disposed sector-shaped plate 32, (Figs. 2 and 3) provided with a stud 32 on which said lever is pivoted, said plate containing a plurality ofperforations 32", arranged concentric with the pivot, and adapted to be engaged by the end of a dog 32 pivotally carried by the lever at its underside. The lever and its dog are so connected that the handles of both can be conjointly grasped by the hand of the attendant, and the dog manipulated to maintain the same disengaged while the lever is swung to engage or disengage the clutch, in either of which positions the latter can be held by causing the end of the dog to enter the appropriate plate-perforation 32 Externally on the frame and approximately in a horizontal planecommon to that and near the adjacent spindle-bearing b, is a stud 37, on which is pivotally secured one end of each of a short bar 37*, and a bar 37*, both having parts curved so that when their straight portions are brought substantially parallel, there'will be considerable intervening space between such portions. Pivo'tally secured to the free end of the bar 37", is a connecting link comprising sections 37, 37, the former of which presents a socket for the sliding reception of the threaded shank of .the section 37 the free end of which is of hooked character to engage a pin 37 laterally on the end of the bar 37 and thereby retain said bar and link in the position illustrated most clearly in Fig. 1. A revoluble nut 37 carried by the socket-section, can be manipulated to cause the threaded shank of the section 37 to travel within or without the socket and thereby contract or extend the connecting rod. By this means the shoes 37 8 carried by projecting at one side of the frame.

transverse companion rollers 25, 26.

scant? the rod and link can be adjusted to frictionally clamp a peripherally rooved pulley s, keyed on the end portion of the roll-spingle,

bviously the degree of friction pressure, can be nicely regulated. The shoes can be of any suitable material, yielding or otherwise, and are preferably beveled and recessed to permit of their intimate conformation with the pulley-periphery.

It will be understood that the shaft 12, extends and is suitably supported at the opposite side of the frame from that before described and at such side communicates through bevel gearing 90, 80, motion to a vertical threaded shaft 2, at that side, and on which latter is a traveling block with a spring bracket arm 15, carrying a spring 15 constructed and coincidently operating in all respects similar to the arrangements of shaft 2, and its block and arm previously described. Short vertical rods 7 and 7", are carried by the standard '2' and block 7 respectively and are adapted to 'bear against the spindle S, at .each end of the paper-roll, so that said spindle and roll will be maintained in true transverse position during its travel and the uniform pay of the web insured.

Angular brackets D, D, are secured to the main frame at both sides thereof so as to provide in a lower plane in proximity to one side of the cylinder O, a pair of adjustable bearing boxes 27, 28, in which are supported the journals of transverse rollers 27, 28*. Bolted to the lower portion of the main frame at each side thereof and a considerable distance below the brackets D, D, are brackets E, E, comprising bearings for lowflrl' the lower part of the frame-extension is a transverse bar F, in which near the ends, slidingly bear longitudinally disposed eyebolts 24, the eyes of which constitute bearings for the short journals of a lower roller 24*, the threaded shanks of the bolts being engaged by hand nuts 24:", whereby the position of the roller 24., can be longitudinally varied.

Led around the cylinder C, and roller 24;, and in contact with the roller 27, are a series of relatively spaced endless tapes 23, of suitable fabric, one of the passes of each tape extending around the underside of and 1n contact with the lower roller 25. Also led around the rollers 28 and 26, are shorter endless tapes 22 which coincide in position with portions of the tapes 23 in so far as their lengths ermit. It will be appreciated that the tension of the tapes 23 can be so regulated by the eye-bolts 24 and their nuts which in fact constitute a tape-tightener, that the positive rotation of the cylinder C, will affect the travel of said tapes. The adjustments of the rollers 24 and 26 should be such that the tapes 23 and 22, should be taut so that the tapes will occupy the relative position illustrated in Fig. l, the upper passes of the tapes 23, frictionally driving the rollers of the tapes 22, by reason of the driving pressure exerted by said upper passes through the intervening thicknesses lower pairs of companion rollers 27, 28,

and 25 and 26*.

In the tops of the brackets E are journaled a transverse rock shaft 21 having rigidly connected thereto, arms 21, close to the inner sides of the frame. These arms carry at their upper ends an angularly disposed blade 21", the free edge of which is serrated as shown in Figs. 3 and 4;, to facilitate its penetrating and severing the contiguous web of paper.

One of the ends of the shaft 21 projects externally for a short distance at one side of the frame and has secured thereto a bell crank lever 21, to one arm of which and to the frame is secured a contractile spring 21, which normally tends to throw the arms 21 and'blade 21" in a direction opposite to that indicated by the arrow, Fig. 1, such mow; ment being limited by a loop 21 on an adjacent part of the frame. Pivotally connected to the arm of lever 21 opposite to that to which the spring 21 is attached, is one end of an extended rod 21, the other end of which is pivotally secured to a bell-crank lever 21 externally at one side of the extension B, said bell-crank lever in turn being connected to the lower end of a vertical rod 21 playing in guides 21, on the extension, said rod carrying at its upper end adjacent to the nearest top bar, a contact roller 21*, in the path of travel of the outer pulley s, of the roll-spindle.

If the parts be in the'positions illustrated in Fig. 1, it will be noted that the end portions of the spindle S of an expiring roll of paper, occupy the bearings b, b, the bars 37 and 37", being retained by the hook link, so that the shoes of said bans frictionally clamp the pulley 8?, on said spindle. Under such conditions, the spindle S, and the core and remainder ofthe paper thereon are not only retained in osition, but the pay of the web is frictional ly retarded to the desired extent in order to avoid a too free paper supply. This web is indicated by a dotted line P, which illustrates the same as descending and passing between the yielding tape surfaces of the rollers 25*, 26*, and then carried up in close contact between the ascending passes of the tapes 22, 23, the web next passing through the yielding pinch of gaged the clutch mechanism. The

the rollers 27*, 28 after'which it continues around the cylinder C, and is fed to the printing mechanism of the press. This feed continues until the paper carried by the spindle S, is about expiring. At this time, a new roll is placed upon the end of'the extension B, withits spindle S resting on the top bars of saidextension and its end portions projecting beyond the same. The bars-7*, and7, arethen arranged so that the link- 7 connects them, with the result that the shoes 7, engage the pulley s, and are caused to frictionally clamp the said pulley with the desired" degree of pressure, by the manipulation of the nut 7. This renders the bodily longitudinal movement of the new roll of paper dependent upon the actuation of the blocks 7 and 7 The end of the web of paper P, with paste applied to the upper surface thereof, is then brought down and laid upon the horizontal upper portions of the't'apes 23 constituting one form of web pathway. The web paperPis carried to and introduced between the pinch of the tapes at the rolls 25, 26 and the movement of said tapes will cause saidpaper P, to travel between the same along with the paper P, and thereby establish a. pasted connection with the latter.

The retarding device embodying the bars 37 and 37, having meanwhile been disengaged, as indicated in Fig; 2, to release the spindle of the expiring roll, the lever 33, is operated and locked to engage and hold enproper revolution of the screw- shafts 1, 1 and 2, 2*, is thus occasioned with the result that the traveling blocks 13, 13 ascend and through the medium of their arms 15, 15 lift the spindle S, and its core and remainder of paper thereon, to an elevated plane.

The blocks 7, 7", coincidently travel forwardly along their screw shafts and the spindle S rolls with a frictional retardation, forwardly along the top bars of the extension B. As the spindle travels forward, the grooved pulley on one of the projecting portions of the idle will contact with the roller 21 and depress the rod 21 so that the latter will through its connections, turn the shaft 21, to throw the blade 21, in the direction of the arrow Fig. 1, and efi'ect the severing of the web of paper 1*, from the expiring roll. Thereafter, as the paper-feed is being conducted from the new roll, the latter and its spindle continues its movement until the end portions of said spindle enter and turn within the bearings b. The clutch mechanism is disengaged at this stage. The bars 37*, 37", together with their connecting link are then adjusted to cause their shoes to clamp the outer pulley on the spindle, and the inner arms 7* and 7 are thrown oil" to release the pulley s, from engagement with the shoes 7 The further draft on the paper is effected by the pull exerted by the feeding means of the press proper. D this period, a hand crank key is applied to the end of the shaft 1, to revolve it and the screw shaft 1, in a; direction the reverse of that which said shafts previously had been revolved, with the result that the block 7, and parts carried thereby as well as the block 7, and its vertical rod 7*, are retracted to a position ready for reaction with a further roll of paper.

Subsequent to the severing of the paper P, and preferably before the reverse movement of the horizontal screw-shafts, the

spindle and core together with the paperremnant of the exhausted roll, are removed from the bracket arms 15. Therefore, when the blocks 7 and 7, are retracted as stated, the vertical shafts 2 will also be reversely revolved to lower the blocks 13, so that their bracket arms will take under the spindle now in operative position, the inclinedfaces of the armends near the limit of their downward movement, contacting with the end portions of the spindle so that said arms will yield to clear 'and thereafteripass under the spindle.

It will be seen from the foregoing description that the pasted end of the new roll of paper is drawn between the yielding pinch of the tapes at the rollers 25*, 26 and pressed into pasted connection with the web from the expiring roll, the two webs being carried up between the ascending passes of the tapes 23,22, which have the efiect of maintaining and guiding the joined webs in a smooth condition for feed to the printing mechanism proper of the press, the bperations being so conducted that the web of the expiring roll of paper will be severed at such period that but a comparatively limited length of the paper P, will conjointly pass with the paper P, to the said printing mechanism. The pinch of the tapes at the companion rollers 27, 28, besides providing for the frictional driving of the tapes, also contributes to the frictional feeding of the paper and serves to efiectuate the pasted connection of the two webs.

By employing the frictional retarding devices for the roll of paper which is in the operative position with respect to the press, as well as forthe roll that is to supersede said first mentioned roll, the paying out of the web from either roll is so regulated and controlled that'the web passing to the machine is maintained under a, proper amount of tension, and hence undue looseness and consequent buckling are avoided. 7

I attach particular importance to the fact that the clamp device carried by the block 7, by engaging within the grooved periphery of the spindle pulley s, prevents any lateral shifting movement of the spindle and its tions of adjusting the pasted end of the paper from a new roll, the engagement and disengagement of the retarding devices and the manipulation of the clutch lever being conveniently conducted by a single attendant.

llaving now described my invention, what I claim as new and desire to secure by Letters Patent, is.
