  • This invention relates to printing machines, the object being to furnish in a machine of this class an improved organization of mechanisms adapted for printingupon a continuously-moving web of paper a series of impressions spaced at predetermined distances from one another and at relatively great distances apart as compared with the distances between the successive series of type-faces carried by the type-form through the agency of which the impressions are produced.
  • This invention is especially adapted and intended for use in obtaining impressions from a'printing-stripsuch,forinstance, as is produced in the mannerdescribed andclaimed in my prior applications, No. 509,985, filed May 3, 1894, and No. 511,910, filed May 21, ISM-which strip is in the nature of a thin metallic sheet having characters formed in relief thereon to obtain a printing-surface; and the object of my present invention is to secure from a formsuch, for example, as the printing-strip described-l1aving such a succession or any.
  • a further object of my invention is to provide, in connection with a printingmachine, an improved inking mechanism whereby an even distribution of the ink maybe obtained over a relatively small type surface irrespective of the size of the inking member, and the uniformity of the inking operation thereby assured.
  • Anotherobject of my invention is to furnish, in connection with web-feeding mech anism for passing a continuous strip of paper through the machine at a predetermined rate of movement and with means for severing such strip at predetermined points in its movement for thereby forming wrappers of a predetermined length a sheet-delivery mechanism embodying means for receiving thewrappers after they are cut from the web and for slowing down the movement of such wrappers to form a pile which may be conveniently handled by an attendant.
  • Another object of my invention is to furnish an improved wiping mechanism where by after the printing-strip has passed beyond the impression members the printing-face thereof will be thoroughly cleaned or wiped, and said strip will be caused to emerge from the machine in substantially the condition in which it was on entering the same,

  • the driven shaft S forms the means for imparting movement to the mechanisms located above the top plate and is shown as having fixedly secured thereto a strip-carrying roller or impression member I in the form of a drum of large diameter, and this drum is illustrated as having at one end thereof a circuit of equidistantly-disposed indentations 13, which are adapted to engage a series of corresponding projections carried by a print ing-strip from which impressions are to be taken.
  • the strip or form employed in the present case is preferably of the character described in my prior applications hereinbefore referred to and is shown as consisting of a strip or sheet 14, which, it will be understood, will usually be of thin sheet-brass having projections 14: on one face thereof and oppositely-disposed character-forming projections on the other face thereof, so that the carrying members or projections of the strip will, when the machine is in operation, be engaged by the corresponding indentations of the impression member I, while the character-forming pro- 'jections of the strip will be on the opposite or outer face of the sheet in position to be inked and to print upon a traveling web of paper moving between the strip and a second impression member, which will be hereinafter more fully described.
  • the printing-strip 14 is shown in the present case as wound upon a carrier-roll 15, carried by a stud 15, secured to the outer end of a bracket 16, rising from the rear end of the top plate 5 of the main frame.

  • the shaft 21 is shown in the drawings as driven by a band-wheel 24, controlled by a belt passing over a driving bandwheel 25, fixedly secured to the shaft 9, which is controlled from the main driving-shaft S.
  • This delivery-reel is therefore simply in the nature of a follower, while the receiving-reel is driven by a belt capable of slipping even when rotating at its highest speedas, for instance, when only a small portion of the strip has been rewound.
  • a torsion-spring is shown at 32 secured at one end to one of the arms 29 of the yoke for the pressure-roll and is secured at its other end to an adjusting-collar 33, mounted upon the carrier 30 and adapted to be turned thereon, a set-screw 34: being shown for binding said collar to the carrier in any of its adjusted positions to thereby secure the desired amount of pressure upon the printing-strip and the cylinder I.
  • a second pressure-roll may be employed, if desired, to engage the strip at the point of egress from the impression members and is shown at 26. I do not, however, consider this roll as essential, as the tension upon the strip due to the rotation of the receiving-reel 1.) will usually be found sufficient to maintain said strip in contact with the cylinder I around the under side thereof.
  • the pressure-roll 26 is substantially a rigid cylinder, but is preferably provided with a thin covering of flexible material, such as rubber, for the purpose of compensating for anyslight unevenness of engagement between the walls of the indentations 13 in the impression-roller I and the complementary projections 14: of the printing-strip, and thereby maintains the strip in constant geared connection with the driver or impression-roll I.
  • the preferred form of mechanism from which I have secured the best results is one in which an even distribution of the ink upon the type-surface may be obtained, irrespective of the area of such surface, and which will also prevent the crawling of the inking member or members upon the face of such type-form.
  • One form of de vices for attaining these results is shown as mounted upon the forward end of the top plate of the machine and as supported between suitable uprights or brackets, such as 34 and 34, and the brackets previously described and designated, respectively, by 31 and 31.

  • These inking-rolls 51, 52, and 53 are not, however, non-yielding, as is the case with some of the other inking-rolls of the series described, but are of the type generally known as composition rolls,which are peripherally yielding and will therefore give slightly in passing over the type-faces and thereby thoroughly distribute the ink upon the type-form. It will be understood, however, that this yielding action of the con1position rollers will not be sufficient to cause a distribution of the ink upon the non -impressing faces of the strip.
  • rollers 51, 52, and 53' are shown (see Fig. 5) as in frictional engagement with t the secondary distributing-rollers 49 and 50' and as slightly separated, peripherally, from one another to thereby permit the rotation of these three composition rollers in the same direction, as will be apparent by reference to said figure.
  • these impression-rollers are in contact with the strip upon the impression-cylinder I,they should of course have the same speed of peripheral movement as said strip upon the impressioncylinder. It will be obvious that the gears should be so proportioned that the secondary distributingrollers 49 and 50 will have equal rates of peripheral movement to that of said cylinder.

  • the rate of peripheral movement of the wiping-rollers 58 and 60 is faster than the rate of advancement of the printing-strip, while the peripheral speed of the wipingroller 59 is considerably slower than such advancing movement of said strip, so that the alternating wiping members or rollers will have, respectively, faster and slower advancing or peripheral movements, the outer rollers wiping the strip in one directionthat is, in a direction corresponding with the direction of egress of the strip from the machinewhile the inner roll willwipe the strip in a direction in opposition to the direction in which the strip withdraws from the machine.

SPECIFICATION forming part of Letters Patent No. 590,002, dated September 14, 189?. p Application filed m 9, 1895. Serial No. 555,390. (No model.)
To-aZZ whom, it may concern.-
Be it known that 1,-lVALTER E. CRANE, a citizen of the United States, residing at Hart ford, in the county of Hartford and Statekif Connecticut, have invented certain new and useful Improvementsin Printing-lvlachines, of which the following is a specification.
This invention relates to printing machines, the object being to furnish in a machine of this class an improved organization of mechanisms adapted for printingupon a continuously-moving web of paper a series of impressions spaced at predetermined distances from one another and at relatively great distances apart as compared with the distances between the successive series of type-faces carried by the type-form through the agency of which the impressions are produced.
This invention is especially adapted and intended for use in obtaining impressions from a'printing-stripsuch,forinstance, as is produced in the mannerdescribed andclaimed in my prior applications, No. 509,985, filed May 3, 1894, and No. 511,910, filed May 21, ISM-which strip is in the nature of a thin metallic sheet having characters formed in relief thereon to obtain a printing-surface; and the object of my present invention is to secure from a formsuch, for example, as the printing-strip described-l1aving such a succession or any. list of addresses in relief thereon a series of reproductions or a list of different superscriptions or addresses preferably spaced at wide predetermined inter vals upon aweb of paper that a plurality of wrappers such as are usually employed for inclosing newspapers, periodicals,&c.may be cut subsequently to the production of the successive printed impressions and then formed intoa pile for convenient handling.
A further object of my invention is to provide, in connection with a printingmachine, an improved inking mechanism whereby an even distribution of the ink maybe obtained over a relatively small type surface irrespective of the size of the inking member, and the uniformity of the inking operation thereby assured.
Anotherobject of my invention is to furnish, in connection with web-feeding mech anism for passing a continuous strip of paper through the machine at a predetermined rate of movement and with means for severing such strip at predetermined points in its movement for thereby forming wrappers of a predetermined length a sheet-delivery mechanism embodying means for receiving thewrappers after they are cut from the web and for slowing down the movement of such wrappers to form a pile which may be conveniently handled by an attendant.
Another object of my invention is to furnish an improved wiping mechanism where by after the printing-strip has passed beyond the impression members the printing-face thereof will be thoroughly cleaned or wiped, and said strip will be caused to emerge from the machine in substantially the condition in which it was on entering the same,
In the drawings accompanying and forming j part of this application, Figure 1 is a front elevation of a printing machine embodying my present improvements, the paper-roll carrier. and the supporting and retarding devices therefor being removed to more clearly show the construction. Fig. 2 is an end elevation of the same as seen from the right hand in Fig. 1. Fig. 3 is an end elevation of the same, looking from the left hand in Fig.
1. Fig. etis a plan of the machine; and Fig. 5 is a substantially central vertical section of the machine, the section beingtaken in line at on, Fig. 1.
Similar characters designate like parts in all the figures of the drawings.
The operative mechanisms of a machine embodying my present improvements will be carried by some suitable framework. In the preferred form thereof herein shown and described the main framework is illustrated as having a pair of uprights or end frames 2 and 2, connected at their upper sides by a table shown as having a pinion 8", secured thereto end or receiving reel 19 for the strip.
and meshing with teeth of a gear-wheel 9, fixedly secured to a shaft 9, also journaled in bearings at the same end of the framework and carrying in turn a pinion 9, which engages the teeth of a gear-wheel 10, fixedly secured to a driven shaft S, mounted directly above the driving-shaft S and journaled in bearings 12 and 12 in the tops of the end frames 2 and 2.
The driven shaft S forms the means for imparting movement to the mechanisms located above the top plate and is shown as having fixedly secured thereto a strip-carrying roller or impression member I in the form of a drum of large diameter, and this drum is illustrated as having at one end thereof a circuit of equidistantly-disposed indentations 13, which are adapted to engage a series of corresponding projections carried by a print ing-strip from which impressions are to be taken.
The strip or form employed in the present case is preferably of the character described in my prior applications hereinbefore referred to and is shown as consisting of a strip or sheet 14, which, it will be understood, will usually be of thin sheet-brass having projections 14: on one face thereof and oppositely-disposed character-forming projections on the other face thereof, so that the carrying members or projections of the strip will, when the machine is in operation, be engaged by the corresponding indentations of the impression member I, while the character-forming pro- 'jections of the strip will be on the opposite or outer face of the sheet in position to be inked and to print upon a traveling web of paper moving between the strip and a second impression member, which will be hereinafter more fully described.
The printing-strip 14 is shown in the present case as wound upon a carrier-roll 15, carried by a stud 15, secured to the outer end of a bracket 16, rising from the rear end of the top plate 5 of the main frame. The strip 14 is fed into the machine over the upper side of the impression-cylinder I and is carried out around the under side of said cylinder and also along the under side of a guide-plate l7, fixedly secured to a standard or upright 18, rising from the top plate 5 and shown here in as bolted thereto. The bracket 16 is also illustrated in the drawings as having a shaft journaled therein at 19 and carrying a sec- The shaft 19 is shown as guided in lateral direction by means of the usual collars abutting against the opposite ends of the bearing for the shaft and as also having fixedly secured thereto at one end a driving-pulley 20, controlled from a shaft 21, journaled at its opposite ends, respectively, in the standard 18 and a bracket 22 and carrying a similar driving-pulley 23. The shaft 21 is shown in the drawings as driven by a band-wheel 24, controlled by a belt passing over a driving bandwheel 25, fixedly secured to the shaft 9, which is controlled from the main driving-shaft S.
It will be understood, of course, that a sufficient portion of the printing-strip 14: is left blank at the end which enters the machine to permit attachment of said strip to the receiving-drum 19 before the printing operation is begun and that the peripheral movement of the receiving-reel is at the same rate as that of the impression member I, in order that the strip may be properly rewound after it has passed out of the machine, the delivery-reel 15 being of course driven by the pull of the strip itself and not being geared directly to any portion of the driving mechanism. This delivery-reel is therefore simply in the nature of a follower, while the receiving-reel is driven by a belt capable of slipping even when rotating at its highest speedas, for instance, when only a small portion of the strip has been rewound.
For maintaining the printing-strip in engagement with the drum I prefer to employ means independent of the devices hereinbefore described for pressing the printing-strip directly against the impression member I. One form of device for attaining this result is shown at 26 as a pressure-roll fixedly carried by a shaft 27, mounted for rotation in bearings 28, carried in the ends of the lateral arms 29 of a yoke which is sleeved upon a cylindrical rod or carrier 30, carried at its opposite ends by the uprights or brackets 31 and 31, which are shown as rising from the top plate 5. As a means for varyingv the pressure exerted by the roll 26 upon the printingstrip a torsion-spring is shown at 32 secured at one end to one of the arms 29 of the yoke for the pressure-roll and is secured at its other end to an adjusting-collar 33, mounted upon the carrier 30 and adapted to be turned thereon, a set-screw 34: being shown for binding said collar to the carrier in any of its adjusted positions to thereby secure the desired amount of pressure upon the printing-strip and the cylinder I. A second pressure-roll may be employed, if desired, to engage the strip at the point of egress from the impression members and is shown at 26. I do not, however, consider this roll as essential, as the tension upon the strip due to the rotation of the receiving-reel 1.) will usually be found sufficient to maintain said strip in contact with the cylinder I around the under side thereof.
The pressure-roll 26 is substantially a rigid cylinder, but is preferably provided with a thin covering of flexible material, such as rubber, for the purpose of compensating for anyslight unevenness of engagement between the walls of the indentations 13 in the impression-roller I and the complementary projections 14: of the printing-strip, and thereby maintains the strip in constant geared connection with the driver or impression-roll I.
For the purpose of inking the type-form or printing-strip as the same passes around the impression-cylinder I the preferred form of mechanism from which I have secured the best results is one in which an even distribution of the ink upon the type-surface may be obtained, irrespective of the area of such surface, and which will also prevent the crawling of the inking member or members upon the face of such type-form. One form of de vices for attaining these results is shown as mounted upon the forward end of the top plate of the machine and as supported between suitable uprights or brackets, such as 34 and 34, and the brackets previously described and designated, respectively, by 31 and 31. The uprights 34 and 34 form the side walls of the usual ink-fountain and support the usual obliquely-adj ustable doctor 35 in operative relation with a ClOOtO1l0ll 36, carried by a shaft 36, journaled at its opposite ends in the brackets 34and 34 and carrying at one end a ratchet 37, fixedly secured thereto for rotating the doctor-roll. As a means for transferring the ink from the doctor-roll to the distributing-rolls,which will be hereinafter described, I have shown herein a transfer-roll 38, carried upon a transverse shaft 38, which is mounted for rotation in bearings formed in the upper ends of a pair of rockarms 39 and 39, fixedly secured to a rockshaft 40, journaled at its opposite ends at the rear sides of the brackets 34 and 34.
The doctor-roll and the transfer-roll are illustrated in the drawings as operated from the main or upper driven shaft S by means of an eccentric 41, controlling an eccentricrod 42, which is pivoted at its forward end to therock-arm 39 by means of a stud 43, which is also shown as carrying a pawl 44 in position for engaging the teeth of the ratchetwheel 37 on the successive actuations of the rocking frame by the eccentric-rod.
The primary distributing-roll, by means of which the ink is taken from the trausfer-roll 38, is shown at 45 as carried for rotation with a shaft 45, which is journaled at its opposite ends in the forward ends of the up rights or brackets 31 and 31. This distributing-roller is illustrated in the present case as driven directly from the main upper driven shaft 8 and as constituting the means for rotating in turn the several other inkin g-rollers,whioh are illustrated as constituting parts of the inking apparatus. In the present case thedistributing-roller 45 is shown as driven The inking mechanism is also preferably pro vided with a plurality of secondary ink-distributing rollers driven from the primary distributing-roller 45,three-of these rollers being shown herein at 48, 49, and 50 as carried by oorrespondin g shafts 48, 49, and 50, mounted at their respective ends for rotation in bearings in the brackets 31 and 31 and in paral- 49 and 50 are illustrated as carrying gear-' wheels 49" and 50, respectively, having relatively narrow faces, these gear-wheels being adapted to mesh with the teeth of the wide gear-wheel 48, so that the rolls 40 and 50' willrotate in the same direction.
The two secondary distrilniting-rollers 49' and 50, which derive their movements from the primary distributing-roller 45, are preferably metallic rollers, so that the peripheral surface thereof will be nonyielding.
As a means for inking the type-form or t3 pesurfaces of the printing-strip, I have shown as'a part of the inking mechanism threerollers (designated, respectively, by 51, 52, and 53) carried, respectively, by corresponding shafts 51, 52, and 53, journaled at their opposite ends in the brackets 31 and 31, preferably adjustably. These inking- rolls 51, 52, and 53 are not, however, non-yielding, as is the case with some of the other inking-rolls of the series described, but are of the type generally known as composition rolls,which are peripherally yielding and will therefore give slightly in passing over the type-faces and thereby thoroughly distribute the ink upon the type-form. It will be understood, however, that this yielding action of the con1position rollers will not be sufficient to cause a distribution of the ink upon the non -impressing faces of the strip.
All of the rollers 51, 52, and 53' are shown (see Fig. 5) as in frictional engagement with t the secondary distributing-rollers 49 and 50' and as slightly separated, peripherally, from one another to thereby permit the rotation of these three composition rollers in the same direction, as will be apparent by reference to said figure. As all of these impression-rollers are in contact with the strip upon the impression-cylinder I,they should of course have the same speed of peripheral movement as said strip upon the impressioncylinder. It will be obvious that the gears should be so proportioned that the secondary distributingrollers 49 and 50 will have equal rates of peripheral movement to that of said cylinder. Hence if the rollers 51, 52, and 53 shrink during use, as is generally the case, by adjusting the parts so as to maintain such composition rollers constantly in engagement with the cylinder I and the rolls 49 and 50 the same rate of peripheral" movement will cured in place by the usual bolts passing through suitable slots in the top plate of the machine and secured in place by nuts in the usual manner.
In order to more thoroughly distribute the ink over and around the composition rollers, the secondary distributing-rollers are preferably actuated to have longitudinal or reciprocatory, as well as rotary movements. Any suitable means may be employed for this purpose; but in the preferred form thereof herein illustrated I have shown the shafts 49 and 50 as passing, at the ends thereof opposite the gearing previously described, through a yoke 54, which yoke is illustrated herein as working between suitable stop-collars secured to said shafts and as having a pivotal connection with the forward end of an actuatinglever 56, which is pivoted in turn to a projecting arm 31", carried by the bracket 31, said lever being shown as having at its opposite end a stud and roller working in a camgroove 57 of a cam-wheel 57, carried by the driven shaft 8. It will be obvious that 011 the rotation of this shaft the lever 56 will be oscillated about its pivot and will thereby reciprocate the secondary distributing- rollers 49 and 50 longitudinally, the wide teeth of the actuating gear-wheel 48 for these rollers serving to maintain the driven gear- wheels 49 and 50 in constant engagement with the teeth of said driving-gear.
After the printing-strip emerges from be tween the impression members the ink may be removed therefrom by any suitable wiping mechanism. That which I have shown herein embodies a plurality of wiping members or rolls in contact with and movable in relation to the printing-face of the strip or member to be wiped, so as to wipe in alternately opposite directions, the strip being held at its rear face by contact against the under side of the guid eplate 17, hereinbefore referred to. The guide for engaging the rear side of the strip may be of any suitable construction,but is preferably formed as shown in the drawings, in which the guide-plate 17 is illustrated as fixedly secured to a series of horizontallydisposed guide-carrying arms 17, which may be made fast in any well-known manner to the standard 18 or may be formed integral therewith. The wiping-rolls, which are designated herein by 58, 59, and 60, are shown in the drawings as having their wiping or outer surfaces formed of yielding material carried upon substantially rigid inner rollerssuch as 58", 59, and 60"which in turn are fixedly secured to corresponding shafts 58 and 59 and the shaft 21, which are mounted for rotation in bearings carried by the bracket 18. At the ends thereof which are adjacent to such bracket these shafts are shown as provided with gearwheels 61, 62, and 63, connected by idlerwheels 64 and 65, carried upon studs which are also mounted on the bracket 18. The gear 61 is shown as constituting the driver for this train of gearing and, as is obvious, will be driven by the rotation of the band-wheel 24. The two gears 61 and 63 are of relatively small diameter, while the gear-wheel 62, which drives the intermediate wiping-roller, is shown as of relatively large diameter, whereby the two outer wiping-rollers, it will be seen, will be driven at a relatively rapid speed, while the rotation of the intermediate roller will be at a relatively slow rate. In the present case the rate of peripheral movement of the wiping- rollers 58 and 60 is faster than the rate of advancement of the printing-strip, while the peripheral speed of the wipingroller 59 is considerably slower than such advancing movement of said strip, so that the alternating wiping members or rollers will have, respectively, faster and slower advancing or peripheral movements, the outer rollers wiping the strip in one directionthat is, in a direction corresponding with the direction of egress of the strip from the machinewhile the inner roll willwipe the strip in a direction in opposition to the direction in which the strip withdraws from the machine.
In practice I prefer to construct the wipingrollers in such a manner that they may be readily placed upon and removed from their respective driving-shafts for the purpose of renewing the cylinders when the same become worn and for cleaning the same from time to time. The wiping-face or yielding portion of each of these rollers is shown in the drawings as formed of material which will be considerably flattened while rotating in contact with the printing-strip, the rollers being preferably made up of a plurality of disks of cloth or other suitable material for cleaning a form.
The main driving-shaft is shown as having at the end thereof carrying the driving-pulley (not shown) a gear-wheel 66, having a geared connection with the feeding means or feedrollers, by means of which the speed of movement of the web of paper is controlled as the sheet passes through the machine. In the present case the main feed-roller is shown at 67 as having upon the outer end of its shaft, which is journaled in suitable bearings in the end frames 2 and 2, a pair of gear- wheels 67 and 67 in mesh, respectively, with the gearwheel 66 and with a gear-wheel 68, carried by the other feed-roll 68. This latter feed-roll is shown in the drawings as mounted for rotation in bearings carried by rock-arms 69 and 69', fixedly secured to a rock-shaft 70, journaled in bearings in the end frames.
The feed-rollers constitute feeding means operative for feeding the web of paper into and away from the machine at the same rate of speed.
For the purpose of adjusting the position of the roll 68, which constitutes the pressureroll of the pair, relatively to the other feed-roll 67 the rock- arms 69 and 69 are also illustrated as having fixedly secured thereto lugs 71, vertically bored for the reception of adjusting-screws 72, carrying at the point thereof a flanged cap-piece 72, around which one ICC , ward side of the machine.
-reaching the feed-rollers, which have just end of a coiled spring 10 is passed, the other end of said spring being shown as received by asuperposed pin or boss 74, depending from the under side of the top plate 5. It will be understood that more than one of these adj usting devices will be employed and that by turning the screws 7 2 and properly adjusting the check-nuts 72 an y desired amount of tension upon the pressure-roll 68 may be obtained.
For the purpose of controlling the speed with which the web of paper-is fed throughthe machine the gears 66 and 07 may be changed and other gears having a different ratio of speed transmission substituted therefor, so as to obtain any desired ra Le of peripheral movement of the feed-rolls, and thereby also the required length of wrapper.
The paper-roll R, from which the wrappers are to be formed and upon which addresses or other matter is to be printed, may be mounted at any suitable place adjacent to the machine, but is herein shown as preferably carried by a roller mounted in bearings upon an auxiliary supporting-frame carried at the for- In the drawings the paper-roll carrier is shown at 7 7 as mounted in the bearings of a frame or bracket formed by arms 75 and 76, one of which brackets is carried adjacent to each end of the 1nachine. For the purpose of preventing an uneven or racing movement of the paper-roll and thereby preventing slacking of the web the paper-roll carrier is shown herein as having a stress exerted thereon by retarding means preferably in the form of a friction-.
clamp. In the present case this friction-clamp is shown as comprising an arm 78, fixedly seare shown as adjusted and connected by a bolt 80 and a holding-nut 81.
As the moving web of paper enters the machine from the paper-roll B it first passes over a guide-101182, which is journaled at its opposite ends in the arms and 69 of the rocking frame, which carries the pressure feed-roll 6S, and the traveling sheet then passes around the take-up rollers of a speed modifying or web-take-up mechanism before been described as operative for advancing the paper through the machine.
The impression member or platen,by means of which the paper is pressed against the impression-face of the type-form or printingstrip, is shown herein atP as carried by arms or levers mounted on eccentrics, preferably integral with the main drivin g-shaft S. These arms are illustrated herein at 83 as substantially vertically disposed and as having bearings 83, in which the eccentrics 84 rotate. The upper ends of the arms 83 areillustrated as. curved, to avoid interference with the shaft S, and as having pivotal connections with links 85, of a bent or curved form,which pass under the shaft S and are pivotally secured at their rear ends to a fixed portion of the frame.
The platen proper is preferably in the form of a channeled bar fixedly secured to the arms 83 and substantially rigid, so as to prevent springing thereof. In the channel of the platen-bar, which channel is shown form ed in the face of the platen, I preferably build up several strips of flexible material supported upon a metallic strip in the bottom of the groove, adj usting-screws being shown at 86 as passed through the under side of the platen-bar for slightly raising these strips when necessary to secure a true impressionsurface.
The take-np mechanism,by means of which the movements of the web in passing through the machine are modified, is shown herein as operated from the lower ends of the arms 83, connecting- rods 87 and 87" being illustrated as pivoted to these arms at their lower ends and as also having pivotal connections with the lower ends of levers or rock-arms 8B and 88', which carry the take up members or rollers. These levers are also illustratedas adj ustably clamped to rock- shafts 89 and 89, journaled in bearings in adjustable supports 90 and 90, carried by the main frames 2 and 2, it being understood that the construction shown in Fig. 5 is duplicated at the opposite end of themachine. (See Figs. 2 and 3.) At the points where the rocking levers SS and 88 are secured to the shafts'89 and 89' each of these shafts has a reduced portion on which is fixedly mounted a collar, such as 91 or 91, having a transverse guideway in its outer face,'in which the rock-arm is seated and may be adjusted longitudinally therewith,a check: nut, such as 92, being shown mounted on a threaded portion of each of the reducing ends of the rock-shafts to thereby clamp the rockarm against the collar to hold these parts in fixed engagement with one another. The bearings in which the ends of the rock-shafts are mounted for oscillation are illustrated in the drawings as carried at the lower ends of the supports 90 and 90', which are shown as vertically adjustable in guides 93 and 93 in the end frames of the machine, the supports being adjustably secured in any desired vertical position by means of bolts passed through slots in the adjustable supports or hangers and held in place by clamp-nuts in the usual manner. At the upper ends of the rock-arms or levers 88 and 88 the take-up members or rollers, which act directly upon the moving web of paper to modify t-hem'ovements of the same, are shown as mounted for rotation in suitable bearings.
The relative proportions of the several gears in the train of gears from the main driv ing-shaft S to the driven shaft S are such that the driven shaft will only make a small por- 1 tion of a revolution for each revolution of the driving-shaft, and in practice it has been found convenient to let this equal the one twenty-fourth part of a revolution and to place the addresses upon the strip at such distances apart that twenty-four of them will pass a given point during one revolution of the impression-cylinder, and hence one address will be presented to the platen at each revolution of the driving-shaft S. \Vith reference to this slow advancing movement of the printing-strip it is desired to have the paper upon which the addresses are to be imprinted advance at a much greater rate or a whole wrapper length, and this advance should be at a uniform and predetermined rate, and the rate of movement of the paper as it leaves the roll should be uniform and substantially the same as the peripheral movement of the feed-rolls; but as it is necessary to slow down the rate of advance of that portion of the paper upon which an impression is to be made to precisely the rate of advance of the printing-strip in order that the impressions shall not be blurred I have provided the two similar sets of take-up devices before mentioned which oscillate in unison with each other and in unison with the eccentric upon the main shaft, by means of which the impressions are made, and by this oscillatory movement an alternate acceleration and retardation of that portion of the paper between the said take-up rolls is caused, the retarding effect being sufficient to compensate for the difference between the rate of advance of the printing-strip and the normal rate of advance of the web of paper and the acceleration being sufficient to compensate for the retardation. This take-up is rendered suffieient by reason of the multiplying action of the arms 83 upon the rock-arms 88 and 88', and by reason also of the doubling of the paper about the take-up rolls, as shown, equal and synchronous retarded or accelerated movements in the same direction being imparted to the take-up members or rolls by means of the eccentrics through their connections with said take-up rolls.
The friction-clamp before mentioned prevents the paper-roll from rotating faster than the feed-rolls require the paper to advance, and thus prevents slack in the paper.
The movements of the mechanisms are so timed that as the platen reaches the extreme upper position in its elliptical path and is brought to the impression-point the moving web of paper between the impression members will be traveling at its slowest rate of speed, which minimum rate of movement will be exactly equal to the rate at which the two impression members are moving, and at the moment the impression is produced the impression members and the paper will be advanced with equal speeds. This slowing down of the movement of the impression portion of the web is due to the tipping of the take-up rolls to the right, (seen in Fig. 5,) the throw of the eccentric 84 and the movements of the several levers operated thereby being so proportioned that any desired ratio between the movements of the paper and the printing-strip (within limits) may be obtained, so that the impressions may be produced upon the paper at greater or less distances apart, as desired. The movements of the take-up rolls will always be equal and in the same direction, and, therefore, a giving up of the paper by one of said rolls will always be compensated for by the taking up by the other roll of an equal portion of the web during the same period, so that whatever may be the rate of movement of the impression portion of the web relatively to the movement of the printingstrip the moving web will be constantly maintained taut at all points between the paper roll and the feed-rolls.
If the rate of peripheral movement of the impression member I is assumed to be one and the constant rate of peripheral movement of the Web at the feed-rolls and the paper-roll is sixteen when the impression portion of the web is slowed down to the speed of said impression members at the moment of impression, the take-up rolls will be moving to the right (see Fig. 5) at such a rate as to subtract fifteen-sixteenths of the movement of the impression portion of the paper and cause said impression portion of the web to advance at a speed only equal to that of the impression member I, and when the impression members are in their positions of maximum separation the take-up rolls will add to the normal rate at which the impression portion of the web is advanced by the feed-rolls an amount equal to that which was subtracted during the impression period in order to compensate for the loss of movement of the web during that half of a revolution in which the impression was previously made.
For the purpose of securing positive coaction of the platen and impression-cylinder during the printing moment I prefer to employ, in addition to the geared connections, locking means for positively controlling the positions of these members at such time. In the presentinstance I prefer to employ in connection with one or more locking members secured to the shaft S such as the gear-wheel 10, (shown in Fig. 2 and in dotted line in Fig. 5,) a corresponding locking member or mem bers in the form of a tooth or teeth, such as 96, suitably secured to the platen mechanism and preferably carried by the arm or arms 83. As the two impression members approach each other just prior to the imprinting of an address upon the moving Web of paper this tooth or teeth will engage between corresponding teeth of the gear-wheel upon the shaft S and will positively lock the impression members against slippingat the moment of impression. It will be obvious that these teeth are so disposed that the tooth-spaces will come into positive vertical or radial alinement with the corresponding locking member or members at the printing moment.
Aft-er the paper is fed through the feedrolls it is directed in some suitable manneras, forinstance, by means of aguide-plate 07- toward a cutter mechanism, by means of which the moving strip is cut into single sheets or wrappers of a predetermined length.
In the form thereof herein illustrated the cutting or shearing devices are shown as carried by a cutter-frame adjustably mounted between the end frames 2 and 2 of the main frame and beneath the feed-rolls and the guideplate. The preferred form of this mechanism is shown herein as embodyii'ig a frame having a shear-bar 98, fixedly secured to brackets or hangers 09 and 00, which brackets have journal-bearings adapted to support for rotation a cuttcr-shaft 100. The cutter-frameas a wholeis obliquely adjustable and is shown as adjustably secured to the forward sides of the frames 2' and 2 by means of suitable fastening-bolts, such as 101 and 101,, passed through slots 102 and 102, formed in lugs or shoulders 103 and 103, which constitute parts of the cutter-frame, the bolts being held in their adjusted positions by nuts in the usual manner. The slots 102 and 102 are shown obliquely disposed, and the latter as of greater length than the former, so that the framemay be adjusted up and down on the main frame of the machine, and also in radial direction relatively to the inner pitch-line of the gears and 110, hereinafter described, as a center. 7
The cutter-bar 98 is shown herein as having adjustably secured thereto a stationary cutter or shear 101 the cutting edge of which is substantially adjacent to the lower edge of the guide-plate 97. As a means for cutting the moving web of paper into sheets or wrappers of a determined length as successive portions of the web pass the edge of the shear 104: the shaft 100 is shown as having fixedly secured thereto,.for rotation therewith, a series of cutter-carrying arms 105, to the outer ends of which the movable cutter or shear blade is shown at 100 as bolted in such a position as to cut spirally or in a diagonal line, one end of the blade being about fifteen degrees ahead of the other, as will be evident by reference to Fi 5. The arms 105 are also shown herein as connected atthe ends thereof opposite the shear 100 by means of a balancebar 107.
It will be obvious that in order to permit the vertical adjustment of the cutter-frame carrying the shaft 100 the end frames 2 and 2 of the machine should be provided with openings, as shown at 108. This shaft is illustrated in the drawings as driven by a gear-wheel 100, secured to the end thereof and meshing with a corresponding gear-wheel 110, carried by the main driving-shaft, these two gears being of equal dimensions in order that the cutter-shaft may rotate at the same speed as the main driving-shaft S. As the angle at which the shear-blades cut the moving strip is regulable by the vertical ad just ment of the cutter-frame it will be obvious that the gear-wheel 100 will be tipped slightly out of its true working position and will engage the teeth of the gear-wheel at a slight angle to a vertical line, so that in case of a considerable tipping of the shear-frame the ends only of the gear-teeth will be in proper meshing engagement. This, however, is amply sufficient for properly rotating the shear, as l have found in practice.
The spiral disposition of the revolving blade will, it is evident, cause the severing of the successive strips from the web by a shear cut, while the vertical adjustment of the shear-frame as a whole will insure the obtainment of a straight out across the paper with different rates of movement of the pa per, the vertical position of the cutter-frame being altered by raising or lowering the same as the web is fed through the machine at a faster or slower rate of movement, corresponding to a lower or shorter length of wrapper.
For the purpose of preventing wear of the edges of the shear-blades I have shown herein an oiling device for oiling the rotating shear during its operation. The brackets 09 and 99 are provided with lugs extending through the openings 108 in the end frames 2 and 2, and to these lugs carrier-arms are shown at 112, secured by means of screws 113. These carrier-arms are also illustrated as supporting a bar 11 1, having secured thereto a trough for carrying a supply of oil, a strip of felt or other yielding material being shown at 116 as secured in the outlet of said trough and closing said outlet, the edge of the strip being disposed in such position that it will touch the edge of the rotating shear-blade at each rotation thereof.
As the moving web is severed on successive lines as it passes between the shear- blades 101 and 106 the sheets separated therefrom fall and are received by a universally-adj ust able sheet-delivery mechanism by which they are formed into a pile for handling.
sheet-delivery apparatus consists,essentially, of a sheet guiding or receiving mechanism and a sheet-transfer mechanism vertically and horizontally adjustable relatively to the main frame and a sheet'flier adjustable relatively to the'transfcr mechanism, all cooperating for piling the successive sheets. guiding mechanism in the form thereof shown in the drawings is preferably carried by a shaft 117, carried by bearings 118, vertically and horizon tally adjustable on the end frames 2 and 2 by means of bolts passing through enlarged openings 119, (shown in dotted lines in Fig. 3,) in which openings said bearings may be floated, the bolts being screwed into the frames 2 and 2. The shaft 117 is also shown as carrying at its ends a pair of arms 120, provided with bearings 120 at their upper ends, in which bearings a roller 121 is shown as mounted for rotation. The arms In the preferred form thereof herein illustrated this The sheet 120, it will be understood, constitute the frame of the sheet-guide and are secured adj ustably to side frames 130 of the sheet-transfer mechanism hereinafter described, so as to hold the same in proper position. The usual setscrews or clamping-screws may be employed for this purpose. The shaft or roller 117 also constitutes the driving-roller for the sheet transfer mechanism and is illustrated herein as driven by a band-wheel 122, operated by a belt from a corresponding band-wheel 123, carried by the main driving-shaft S.
For the purpose of receiving and guiding the several sheets or wrappers endless traveling carriers or tapes are shown at 124 as carried around the rollers 117 and 121 and as continuously moving in the direction of travel of the paper.
The sheet-transfer mechanism, by means of which the sheets are conveyed to the sheetfiier or delivery-frame, is shown herein as embodying a plurality of oppositely-disposed carriers or tapes in two sets (designated by 125 and 126, respectively) and traveling in opposite orbital directions, so as to draw the sheets along between them. The tapes of these sets in the present instance are carried by a plurality of rollers mounted in the adjustable side frames 130, which are shown connected by means of tie- rods 127, 128, and 129. The rollers 131, 132, 133, and 134 are illustrated herein as mounted at their ends for rotation in bearings formed on the sets of links 131, 132, 133, and 134, adjustably secured to the side frames 130 by means of clamping-bolts, while a fixed roller is shown at 135 as constituting the lower terminal-roll for the upper series of tapes. The tapes of the lower set are shown herein as carried by the main driving-roller 117 and by the rollers 136, 137, and 13S, mounted adjustably in substantially the manner just described with reference to the adjustable rolls carrying the upper series of tapes.
An additional adjustable roller for tightening the lower set of transfer-tapes is shown at 139 as mounted in bearings in strap rods or hangers 140, mounted on and depending from the opposite ends of the bearings of the driving roller or shaft 11.7. As a means for holding the roller 139 in any of its adjusted positions the side frames are shown herein as having clamping means, preferably in the form of clamping-blocks 141, frictionally engaging the inner sides of the lower ends of the hangers, as shown in Figs. 1 and 5, and secured in place by means of screws or bolts, such as 142.
The tapes of the upper and lower transfer series are preferably disposed in opposition in order to obtain a firm hold upon the successive sheets and also in alternation with the tapes 1 24, said transfer-tapes being driven at a considerably slower speed than the rate at which the web is traveling through the machine, and consequently slower than the movement of each of the severed sheets or wrappers as it falls upon the receivingtapes.
The upper set of transfer-tapes holds the sheets firmly against the lower tapes 125 as the wrappers are received from the guidetapes 124, and it will be apparent that in order to properly carry the wrappers, which, owing to the relatively-slower movement of these tapes as compared with the rate of movement of the paper-web, will slightly bank up upon one another and overlap, the trans fer-tapes must be held taut during their travcling movements. All of the adjustable rollers may be properly set for this purpose, but usually it will be found sufficient for the purpose of taking up slack in these tapes to adjust only the carrier- rolls 131, 134, and 139.
As my improved machine is intended for use in handling sheets or wrappers of different lengths it will be apparent that some means must be employed for so adjusting the sheet-guide and the sheet-transfer mechanism that the severed sheets may be properly engaged and carried between the transfertapes, both when the machine is operating to cut sheets or wrappers of relatively short length and when the severed pieces are of relatively great length. Moreover, for different thicknesses and kinds of paper I have found that the angle at which the tapes move must be varied in accordance with the nature of the web. I-Ience both the frame for the guide-tapes and the frame for the transfertapes are illustrated as capable of adjustment about the driving-roller 117 as a center and on which roller they are mounted.
The adjustment of the frame for the guidetapes has already been described. That for the transfer-tapes is illustrated herein as controlled by means of links 143, pivotally secured to the side pieces 130 of the frame for the transfer-tapes, said links being shown as adjustably secured to the main frames 2 and 2 by clamp-screws 144, set in these frames and working through slots in the links.
As a means for controlling the point at which the severed sheets or wrappers are engaged by the transfer-tapes the adjustable guide- rolls 132 and 136 are shown herein as having not only an adjustment by means of an adjustable link connection with the framepieces 130, but are also illustrated as adapted to have a greater range of movement by the engagement of their respective clampingbolts in the several bolt- holes 132 and 136". By advancing these rollers 132 and 136 nearer to or moving them farther from the cutterblades it will be seen that any length of sheet or wrapper within the limits of the machine may be engaged at its forward end at the proper point as it is being severed by the cutters.
The paper-flier or delivery-frame is shown herein as adjustably mounted on the frame of the sheet-transfer mechanism and adjacent to the discharge-point of the transfer- ITC tapes. In the form herein illustrated the paper-flier has a pair of side frames or arms 145, adjustably mounted by means of bolts 145, working in slots 145"-of the side frames 130, provided with bearings at their opposite ends, one set of which rotatively carry a driving-roller 146 and the other pair of which carry a driven roller or follower 1417, Fig. 4. These rollers are also shown as connected by a set of tapes 148. In the present case the roller 146 is shown herein as carrying a rat-chet- Wheel 146, operated by a pawl 1&9. This pawl is illustrated as carried bya crank 150, secured to the shaft 135, whereby upon successive rotations of said shaft the ratchetwheel 146 is rotated step by step and The sheets of paper are fed gradually forward in the form of a slanting pile as they are delivered to the tapes of the flier by the transfer-tapes, it being understood that the tapes 14.8 will travel at a very much slower speed than the transfer-tapes.
As it is desirable to modify at times the rate of movement of the traveling tapes of the paper-flier the crank 150, which, of course, has its center out of line with the center of the shaft 135, supports the pawl 149 at a point out of line with its own center, so that when the crank 150 is turned relatively to the shaft for adjustment the center of movement of said pawl will be carried nearer to or farther away from the axis of the shaft 135, (see Fig.3,) so that a greater or less number of the teeth of the ratchet-wheel may be engaged on each actuation of the pawl, as may be desired, itbeing understood that the crank will be held in its adjusted position in any suitable manner.
The shaft 135- is shown herein as carrying a grooved pulley 135, actuated from a corresponding pulley 151, carried by the shaft 117, a belt 152 being shown as connecting these pulleys. The shaft 117 receives power, as before stated, from the main driving-shaft through a belt connecting the band-wheel 122 with the band-wheel123. As the ban d-wheel 122 is of relatively great diameter as com pared with the diameter of the band-wheel 123 the shaftll? will be driven with the required relative] y slow speed with respect to the rotation of the cutter-shaft 100.
In some cases it may be found desirable to rewind the printed web of paper after it passes the feedrolls instead of cutting the web into separate sheets. For the purpose of effecting the rewinding of the traveling web a winding-roller is shown at 153 as supported for rotation in bearings carried by a bracket 151, secured to the rear of the main frame. Then the shaft 117 is not operated, the belt connecting the same with the bandwheel 123 will be changed in position for the purpose of operating the roller 153, said roller being disposed at a proper distance from the band-wheel 123 to permit this, and said belt being driven so as to slip slightly and thereby compensate for the increase in the size of the papenroll as the web is rewound upon the roller 1523, the printing-strip It being also rewound'upon its winding-drum in a similar manner, as. hereinbefore described. The cutter mechanism and the sheet-delivery mechanism should then, of course, be disconnected, so as to be thrown out of operation.
The operation of a machine constructed in accordance with my invention, as hereinbefore set forth, will be apparent.
As the web of paper is fed from the roll R into the machine it passes over and around the guide-roll S2 and the take-up roll 94, thence over the platen P, thence around the take-up roll, and thence passes out between the feed- rolls 67 and 68, the movement of the paper at the roll R and the feed-rollers, respectively, being maintained constant by the connection of the feed-rolls with the main driving-shaft and by the stress exerted upon the paper-roll carrier by the retarding means or friction-clam p. As the take-up rolls move back and forth in unison with the impression movement the advance of the portion of the web between said rolls will be alternately retarded and accelerated as the platen P moves toward or from the impression-cylinder I. The form or printing strip is carried around this impression'cylinder at a constant and relatively slow rate of speed, and during its passage around such cylinder is inked by the composition inking- rollers 51, 52, and 53, which revolve at a uniform peripheral speed. At ,the moment of impression the 'take-up' rolls are moving to the right, as seen in Fig. 5, at their maximu in rate of movement in this direction. As the impression is produced the two impression members-via, the platen P and the cylinder I-are locked against slipping by the engagement of the tooth 96 between corresponding teeth of the gear-wheel 10. As soon as the impression is produced the platen withdraws from the cylinder I and the take-up rolls begin to move toward the left, as seen in Fig. 5, the eccentrics 84E gradually multiplying the elliptical orbital movementto the right of the lower ends of the rock-arrns 83 during the corresponding movement of the platen to the left in its elliptical orbit, and hence the take-up rolls are come spondingly actuated toward the left until the platen is at its maximum distance from the cylinder I, when said take-up rolls will be moving to the left at their maximum speed. B y this means the necessary speeding up of the portion of the web between the take-u p rollsto a rate very much above the constant rate of movement maintained at the feed-rolls and the paper-rolls is obtained,it being understood that the amount of acceleration of the movement of the web will be equal to the amount of retardation of the same. ,As the rate of movement of the cylinder 1 and the ink rolls is constant and as the advance of the web, although variable, carries the paper forward at a relatively high speed as compared with the movement of the printing strip or form impressions maybe produced upon the moving web at predetermined distances apart, after which the paper will be carried through the feed-rolls and the printing strip will be cleaned by the wiping mechanism and rewound upon the reel or drum 19, which may then be removed from the shaft and laid aside.
As the printed web passes between the f eedrolls its momentum carries it down until the forward edge thereof has passed the guideplate 97 and the guide-tapes 124 and the forward edge of the moving sheet is about to be engaged between the transfer-tapes when the rotating shear severs the web, and the sheet so severed is carried down and delivered upon the paper-flier. As the rate of advance of these traveling tapes of the sheet-transfer mechanism is considerably slower than that of the paper-web each sheet as it is severed by the cutters is retarded in its movement, so that it forms a guide for the forward end of the next succeeding sheet, and hence the successive sheets between the cutters and the flier will be carried in the form of a continuous band of overlapping members, each one of which serves to guide and support the next succeeding sheet. As the sheets pass out through the transfer-tapes and are delivered onto the flier the relatively slow movement of the tapes of the latter arrange the sheets, in the manner well known in the art, in a slanting pile convenient for handling.
My improved maehineis especially adapted and intended for operation at a high rate of speed, its normal capacity being about five hundred wrappers or sheets per minute.
It is obvious that in a machine operating at such a speed all of the cooperating mechanisms must be properly connected and timed in their movements, so that the several operations of impressing the paper, retarding and accelerating the movements of the same, severing the sheets or wrappers from the web, and transferring these sheets to the flier will occur in exact sequence and at predetermined intervals. I have found by practical experiment that in order to properly handle wrappers which are printed and out while the machine is operating at the high rate of speed it is designed to attain peculiarly-effective sheet receiving and transferring mechanism is essential, and also that it is practically impossible to secure good results except by means of devices which can be adjusted to properly compensate for varying conditions of speed and momentum of the sheets as they are cut from the web and for sheets of varying lengths and kinds of material.
