rnm'zrr iadmacnmn To all whom it may concern:

Be it known that IQAnos H. SMITH, a citizen of the United States, residing at the borough of'Bronx, in the city of New York,

. 5 'county'of Bronx, and State of New York.

have. invented certain new and useful Imjprovements in PrlntingsMachines, of which i .the following is a specification, referencebeg' ing had therein to the accompanying draw-f;

My invent-ion relatesto printing machines.

and more particularly to a'ty e of machine having a rotary impression cylinder and adapted to print upon-a'weh of paper.

In the ordinary web printing press whether perfecting or non-perfecting it in customary practice to print upon the paper while it has i 3 continuous movement throughthe machine. and to useplat'es of uniform size for all work done on the particular machine, for on sues ceeding form cylinders in the] machine.

mittent feed of the paper web and to so' control this movement as to avoid waste of paper, 'or' necessitate the use of printing plates of standard sizes upon the plate carrier. In the form of the invention shown. I secure the desired result by a feed mechanism independent of the printing couple but actuated in synchronism therewith, which feeding mechanism is so constructed as to be alternately operative. and inoperative upon the paper web. 'The' controlling means for said feeding mechanism operates aut'omat-ically. and may be so adjusted as to control the ntervals when said mechanism is operative-or inoperative.

In this To prevent'the' formation of slack between the feed mechanism and th'eprin'ting couple, I- provide a paper clamp mechanismthe 1* yti ve immediately upon the {feedin'gf mech anism" becoming-inoperative.

I furthermore provide a controlling. means forthis registering mechanism which will create. slack upon one side of the printing couple and take up this slack on the other f side thereof to permit the adjustment of the machine, even while it, is running. to compensate'for any slight loss of register due to stretching of, orshrinkage in. the paper.

. The invention consists primarily in a printmg maclnne embodying therein a printing couple ncluding therein an intermittently operative impression cylinder and an inter- Inittently operative paper feed mechanism adapted to feed a continuous paper web in relation to. said printing couple whereby the feeding movement of said web will continue during the impression interval and said paper will remain stationary during the. nonprintlng interval; and 111 such other novel features of construction and combination of embodying my invention with thereof broken away;

In the embodiment of my invention shown in the drawings I have illustrated it in conmachineare indicated'at 1 and 2, the form nection with a machine embodying therein both a rotary impression cylinder and a rotary form cylinder, but the invention may be applied tomachines using other types of form cylinders without substantial modification. 7 y

In the drawings the side frames of the cylinder at 3 and the impression cylinder I i or D-roll at While" the machine shown isan engrav1ng,. intaglioor undersurface printing press, the illustration of the printing couple is merely conventional and the inking, wiping and polishing mechanisms are omltted as such are old and Well-known and are not material to an understanding desired source to the shaft 5 of the gear 6.

Fig. 5 is a similar view showing the posi- .t1on of paper with each of my present invention. At. 5 I have shown the main power shaft of the machine carrying the gear 6 in mesh with a gear 7 through which power is transmitted to the form cylinder; Power may be derived from any as the electric motor 8 belted Inthe form of the invention shown, the impression cylinder or D-roll 4: is continuously rotated by means of the meshed gears 9 thereon and upon the form cylinder tion thereto, said mechanism being operative to feed the paper only during the printing interval and becoming moperative immediately upon the disengagement of the impression cylinder or D-roll4 with the 'printing surface carried by the form cylinder. The peripheral velocity of this mechanism is so controlled as to be inaccord with'that of the printing couple.

Inthe form or the invention shown, this mechanism comprises'a pair of frictlon rolle1's 10 and 11, one of which as IO is'driven from the impression cylinder'or D-roll by the chain and sprocket mechanism 12. These rollers are so constructed and arranged that the feeding interval thereof will accord with the impression interval of .the printing couple.

To adapt a machine to work with plates of different dimensions, Fpreferably provide the rollers 10 and 11 with continuous friction surfaces and use acontrolling meanswhereby said surfaces Wlll be pressed together when it is desired to feed the web, andwill be automatically separated when it is desired to prevent a further feeding movement thereof. To insure accuracy in the operation of the feedin mechanism, and

prevent the formation of s ack between the feed mechanism and the printing couple,

and also the feed of the web by the rewinding mechanism when such is used,.I provide a clamping mechanism whichis operative upon the web when'the feed rollers 10 and 11 are separated and is inoperativethereon when said feed rollers are operative.

Th1s clamping mechanism comprises oppositelv disposed'members 13 and 14: having friction surfaces between which the paper ,web' is adapted to pass after leaving the feeding rollers and controlling means for said clamping members, so constructed that dESI AVAlLABLE CO3 The feed rollers and 11 are adapted :o be positively driven by the intermeshing' gears and 21 carried thereby respectively, 1nd the roller 11 is normally thrusttoward :he roller 10 by means of the springs 22 actmg upon bearings 23 slidably mounted in the side frames ofthe machine,

To accomplish the intermittent separa- JlOIl of the rollers 10 and 11, I provide the )pposite ends of one of them as 11 withbear ng disks 24 adapted to 006 erate with cams arried by the other ,rol er as 10; The eight of the riser upon each' of said cams is preferably such as to eparate the friction surfaces of the rollers withoutdisengaging he gears 20 and 21,thus avoiding any possioility of a loss of mesh ofthese gears and a Y, resultant loss, in the synchronism ofsaid gears and the D-roll or momentary delay in the initiation of the feeding movement of" said rollers.

The length of the riser will determine the inoperative interval of the feeding rollers,

and to adapt the machine to a variable feeding movement of the paper in conformity with the requirements of plates of different sizes, I so construct said cams that the length of said risers may be varied as desired. To secure this result, I form said cam of two similar sections 25 and 26, one of which as 26 has segmental slots 27 therein through which project the clamping bolts 28 adapted to secure said cams in any adjusted position.

The clamping member 13 preferably consists of a rotatable cylinder having a friction surface, while preferably the member 14: is non-rotatable and is provided with angular arbors vertically movable in ways in the side frames 1 and 2. The member l l is acted gupon by the springs'29l1aving a, normal.

thrust toward the member 13, The ends of the arbors of the member lthave rotatably mounted thereon, however, circular disks 3O mounted thereon the gears 31 which are driven from the gears 20 .by means of the intermediate pinions 32; The gears 20'and 31 are of the same dlameter to insure accuracy in the timing of the operations of the feeding mechanism and the clamping mechanism.

The feeding cam cooperating with the disk is composed of two sections 33- and 34 the first of which is secured to and movable with the gear 31 and the latter of which is provided with segmental slots 35, through which the clamping bolts 36 project in a manner to permit the setting of the disk 34 in'any adjusted position relatively to the section 33. The cam disks 33' and 34 while similar in construction to the disks 25 and 26 differ therefrom in the length of the riser, the length of the riser upon the composite cam 3334'when adjusted to its full length being equal to the length of the fall uponv thecam 25-26 when the riser is adjus'ted, for its shortest length. This construction results from the necessity for having' the cam 3H4: operative during substantially the entire interval when the cam 25 -26 is inoperative and havingthe clamp:

.ing mechanism inoperative during the entire interval when the feeding mechanism is'operative. The cams upon the gear 20 and upon the gear wheel31 are set at 180 apart and the length of the risers upon these cams respectively is such thatif taken together they would occupy a. full 360.

It is to be observed that while the feed rollers 10 and '11 are positively driven, the

roller 13 is an idler roller and the member 14 is preferably non-rotatable' in order to avoidany possible feed of the paper by the rewinding mechanism.' The disk 30 is made rotatable merely to minimize wear thereon.-

At 37 I have shown. a roll of a continuous paper-Web mounted in suitable bearings 38. Guide rollers 39, 40v and 41 are arranged between said'bearin gs 38 and the printing couple, a guide roller 42 is arranged between the printing couple and the rollers 10 and 11, and a guide roller 43, is

arranged between the clamping mechanism and the rewinding reel.

To adaptthe'machme to printingin registering colors, 'I provide a registering mechanism adaptedto vary the position of the web with relation to the printing couple, this mechanism being so constructed as to be capable of either advancin the web or Withdrawing it. To secure the desired result, I provide means which will impart movement only to that portion'of'the' web adjacent the printing couple thus pern'iitting adjustment for register without disturbing the feeding mechanism or creating permanent slack in the Web.

. In the form of the invention shown, I provide means operative upon opposite sides of the printing couple whereby slack in the web maybe created upon one side thereof and be simultaneously taken up upon the other side thereof. Thls mechanism com- SESTAVAILABLE CCDl prises a support or supports 44 for the guide roller 42, 'slidably mounted in the side frames of the'machine and acted upon by feed screws 45 to impart the desired reciprocatory movementthereto. Mounted between the guide rollers 40 and 41 is a'vertically reciprocatory roller 46 mounteddn a support or supports 47 acted upon by the feed screws 48. The feed screws and48 are of substantially thesame pitch, so as to secure equality in the movement of the rollers42 and 46. Carried by each of the screws 45 is a beveled gear 49 in mesh with a gear 50 carried by the shaft5l. The screw 48 is carried by, and rotatable with a shaft 52 which is operatively connected with the shaft 51 by means of the shaft 53 and the beveled gears 54 and 55 carried thereby, and the beveled gears 56 and 57 carried by the shafts 51 and 5'2-re spectively. The various gears are so set that as the guide roller 42 is moved toward the? printing couple the roller 46, will be simultaneously moved downwardlv' with the same I guantity of movement; and aslthe roller 42 is moved away from said printingjcouple said roller 46 will be raised. ,.,Either or both of the shafts" 51 and 52'areprovidedy'with hand wheels 59-60 by 'which'theytmay be actuated. f 1 The power transmission mechanism extending from the screws 45: to-the screw'48 upon one side of the machine is connected the other gear 49;1 1pon' the other side of the I A -to a similar mechanism on 't-hefiopp'osite side of the machine so as to cause simultaneous uniform movement 0f -both.'- ends of the rollers in any desired manner.- In the drawing's, ,I have shown a chain'and sprocket mechanism 58 extending fromone car 49 to machine. v t The operation of the'herein described-nia-- chine 'is substantially as. follows:

'11 when the orm cylinder is not'in engage- -ment with a plate, and since the riser of the fI-nstarting'arun of the press, the end ofjthe web is drawn from the paper 'roll 37 and passed over the guide rollers 39, 40 and 41' and under the roller 46, thereafter being passed between the form cylinder 3 and im-' pression cylinder or D-roll 4 and about the.

guide roller 42. From the roller 42, the web is passed between the feed rollers 10 and 11 and the clam ingmembers 13 and 14, the .latter of whic may be separated manually to permit the passage of the paper. Theend of the It'willbe observedthat'in order -toz-pere' mit' the" passage of the'ipaper between the form cylinder and the impressioncylinder-rapex is thensecured to the-re- .windingree 15:" 1

'or' D-roll the latter must not be in engagement with a -plate u on the frame.

Since the riser o the cam 25-26 is so set as to be 0 erative to raise the feed roller cam 33-34 is set in a relation diametrically v will'pass'the disk 24 peri'nitting'the springs -22 to force the roller 11 downwardly to an thereof.

opposite to that of the riser upon the cali' 25-26, said feed rollers 10 and :11 will 'b of the cam 25-26 will be engaged with th disk. 24, and the disk 30 will be engaged with the fall pf the cam 33-34. Hence there wil be no feeding movement of the paperas thi; cam members 13 and 14 will prevent tht friction drive 156 of the rewinding' reel 15; exertinga pull upon the paper beyond saio clamping members.

With the continued operation of the ma chine, however, the riser of the cam 25-26 extent to develop the requisite friction upon the paper to insure the feeding movement Simultaneously with this movement of the roller-11, the elongated riser upon the cam 33-34 will engage the disk 30 and raise the clamping member 14, thus permittin the re-Z winding mechanisms to take up t e slack; resulting from the feeding movement of the iollers 10 and '11. The initiation of th feeding movement bythe rollers 10 and 1;!

and the releaseof the clamping mechanism will occur substantially simultaneously with the initial engagement of the impression cyl-i inder or D-roll with the plate, or other print-f ing surface, upon the form carrier 3; and by reason of the fact that the peripheral ve'locity of the feed roller conforms to that of the form cylinder and the D-rol'l, "the paperwill be fed at the proper speed.

t that interval when the impression cylinder or D-roll passes from its engagement with the .plate upon the form carrier, the riser upon the cam 25-26 will become operative upon the disk 24 to raise the feed roller 11 and make said rollers inoperative to cause: a further. feedingmovement of the web. Si-f multaneously withxthe lifting of the roller ll-against the tension of, the springs 22',- the riserupon the cam 33-34 will become inoperative." as to the disk 30 permittingthew c amping member 14 to descend under the control of its springs 29, thus'instantly arresting the feeding movement of the paper by the rewinding mechanism.

It will thus be observedthat I secure with a continuously o eratingrinting couple, an

intermittent fee .of a we in relation there- "ing rollers sponding with the inoperative interval of to, thus permitting that dwell between impressions which is essential in some classes of printing, as from engraving, intaglio or undersurface plates, and permitting the impressions to be brought closely together upon a web with a resultant material saving of paper.

WVith a continued run of the press, the feeding rollers 10 and 11 will be actuated to make them operative and inoperative alternately, the operative interval corresponding with that interval when the impression cylinder or D-roll 4 is in operative engagement with a plate upon the form carrier 3; and the clamping mechanism will be actuated to make it inoperative and operative alternately, the inoperative. interval coinciding with the operative interval of the feedand the operative interval correthe .said rollers.

Under the, conditions above described, it will be observed that the length of the risers upon the cams -26, and 33-34 determines the duration of the. feeding interval of the 'web, which: must correspond with the size of the plate from which the impression is being made as to the length of said plate. Hence, if plates of different sizes are used upon the machine, to effect the maximum saving of paper, cams having risers of different lengths must be used, the length of said risers being determined by the size, or length, of the plate.

By using sectional cams as above described, having similar cam risers upon each section, I am enabled to adjust the length of said risers upon said'cams-so asto avoid the necessity for the substitution of cams when setting the machine for a run with plates of any particularsize. For instance,

' if it is desired to run the machine with a plate smaller than that for which the machine is set at any time,{ the= clamping bolts 28 and 36 are releasedandythe section 26 is turned in either direction according to the position of the. plate upon the form carrier, and the said section is reset by means of the said bolt in its adjusted positioh. This elongation of the risers upon said cam '25-26 will have the effect of prolonging the inoperative interval of the feeding rollers. Then the cam section 34; is turned in the same direction as that of the cam section 26 and to the same extent. thus shortening the riser upon the cam 33- -34, without changing the position of the init al rise of the cam in a way to vary the relative initial operation of either cam. By varying the length of the risers the quantity of the feeding movement of the paper may be regulated.

It will be observed that as to time, the efiect of the feeding rollers and of the cam cchanism. are always reversed and that this reversal extends through'all of the adjustments of the said cam, hence when the riser of the cam 2526 is set for its shortest length, the riser of the cam 3334 will be set for its greatest length, and vice versa.

When the clamping mechanism is inoperative, the member 13 acts merely as a guide roller for the Web, but inasmuch as the gear 31 is loosely mountedupon the arbor of said roller,.the rotation of said roller is entirely independent of that of said gear which is thus permitted to turn continuously with the feed roller 10. While the feeding roller 10 rotates continuously,

it will have no operative efiect in feeding the paper except when the roller 11 is in the operative relation thereto.

In order to adapt the machine for use in color work, I preferably provide the regis-. tering mechanism which I have described. In running a web through the machine, which web has already received one impression, it is necessary to have a succeeding imprint in register therewith. If it is found that as a result of loss of register, it is necessary to advance the web slightly, either of the hand wheels 59-60 are turned so as to rotate the screws 4'548 in a manner to raise the roller 46 and simultaneously thrust the roller 42 away from the impression cylinder or D-roll. The result of this operation will be the creation of slack between the D-roll and the roller 46, which slack will be taken up by the advance of the roller 42. If it be desired to withdraw the paper slightly either hand wheel 5960 is turned in the oppositedirection with the resultant creation of slack between the roller 42 and the D-roll, which slack will be simultaneously taken up by the roller 46 which will be forced downwardly simultaneously .with the retraction of the roller 42. By connecting the mechanisms controlling the rollers 42 and the roller 46 by means whereby said rollersfare simultaneously operated, and to the same extent, I am enabled to effect a movement of only that portion of the web adjacent 'to 'the' D-roll and form cylinder. Byi-limit ing' thelength of the section of web ted upon by the registering mechanism,TI ahgenahled to secure extreme nicety in thempvement oftM paper; and a movementfiw'hich not --require any variances inthe':adjustment/of any other part of the machine. Hence,this registering mechanism may be advantageously used in con unction with a paper feed mechanism, and permits the construction of a machine embodying such a feed mechanism, wherein adjustment for securing register may be had without disturbing the relation of the feeding mechanism to the web, or requiring any change in the adjustments of said feed mechanism.

It is not my intention to limit the invena printing couple including an intermittently operative impression cylinder, an intermittently operative paper feed mechanism adapted to feed a continuous paper web in relation to said printing couple whereby the feeding movement of said web will continue during the impression'interval and said web will remain stationary during the non-printing interval, a pair of friction members between which the web passes after-leaving said paper'feed mechanism,-
