2 SHEETS-SHEET 2 which the following is a specification, ref erence being bad therein to the aceompanying drawings.

The invention relates to a rotary prmtinig ress for printin sheets of apcr or car )oard from an e ectrotype p ate secured to a rotary cylinder the separate sheets being trial in successive y to the printing mechall Hill.

In machines heretofore used for printing cards it has been common to use a. reciprocable llut bed which carries the type form so that the printin is done during the forward movement. 0 the flat type bed under an impression cylinder; then the form has to be moved backward into position for another forward stroke while the cylinder is still revolving. the printing taking place only during the forward movement. In this way the impression cylinder has to make a complete revolution during the return movement of the form, being lifted above the form for that purpose, so that it will not make any impression on the return stroke and thereby causing a lost rotat|onthat is the cylinder has to make two rotations to each impression, so that every alternate rotation is lost movement, or else the cylinder has to be made so large that. the impression will be made during the first half rotation of'the cylinder and during the remaining half rotation it will be out of' contact with the ty e form while the type form is moving bacliward so that in either event there is lost time in printing.

It is common to have a printing cylinder and an impression cylinder for printing on a continuous sheet where a sheet is cut all t at each rotation of the cylinder, as for instance. in Printing news apers, but I am any machine \erettit'ore used for prluting separate sheets or cards, employing a type cylinder and an impression cylinder, in which each card has to be fed independentlv of the others.

The object of the present. invention is to provide a rapid rotary printing press for separate sheets of car board or aper emrotation of the cylinder.

in feeding each sheet to a running guide on 5 one of the cylinders so that the sheet will be properly registered with relation to the eleetrotype plate. The invention also consists in the mechanism for feeding the sheets to said running guide.

The invention will be fully understood from the following description taken in connection with the accompanying drawings, and the novel features will be pointed out and clearly defined in the claims at the close of the specification.

In the drawin ..,--Figure 1 is a side elevation of a macliine embodying the invention. Fig. 2 is a plan of the. machine shown in Fig. 1. Fig. 3 is an enlarged section, partlv broken away, on line 3-3 of Fig. 2

at showing the parts in the position they will occupy after the sheet. of cardboard has been fed from the position shown in Figs. 1 and 2 to engage the guide clips on the impression cylinder. Fig. 4 is a section through the eleetrotype cylinder and a porti n of the impr ssion cylinder. Fig. 5 is a plan of the lower r impression cylinder with a hrt-t of cardlalard engaged with the guide clips. the other parts of the llltttllllll bring removed. Fig. ti i a section on line it ll of Fig. .3 showing the Feed chain for drawing the bottom sheet of the eurdlmnrd l'rrun Ihc hopper which contains the sheets. Fig. i is an enlarged sectional view showin; the mean for clamping the feed ring to the type cylinder.

llcl'crrtng now lo the drnwings,-- ]tt In represent the side walls of the frame of the llllll 'lilllt. in which are journalcd the shafts which carr the cylinders. Mounted upon the frame is the. table It on which is supported the pile of cards or sheets 12 and which also serves as a runway for the sheets. Suitable means are provided to retain the sheets of cardboard in a pile in nopcrlv squared )osition until they are to l out. for ceding to the printin mechanism. The means shown consists o the upright. standards 13, two on each side, and the two )0 ta-ken 1 l'ront standards 14, the front standards ll being secured to brackets to so that the lower ends of the standards l l may he held a short distance above the top of the table 11. clearing the table sullicicntly to allow the forward feed of one sheet at a time. namely the t bottom sheet in the pile 12, through the space below the standards [4. After the holt l tom sheet is posited out, the pile of sheets i will settle down so that the next sheet above 1 it playing a type cylinder and an impression the one which has been removed and which then becomes the bottom sheet in the pile will be in position to be pushed out next in i order.

Any suitable means may be provided for F cylinder m which sheet is primed at each removing the bottom sheet of the pile and carrying it to the mechanism for feeding it shown is as follows: Journaled in suitabilr to tie rintin c linder. The mechanism 1710 mam feature of too invention consists i? p meehanism which will be hereinafter described.

used instead ot' cardhoard, some other form j of feed mechanism may he employed to feed rings 31 should be prevented from rotation hearings, as for instance in the side walls 10, l l". of the frame, are twoshatts 16, 17. the shaft 16 having mounted thereon at some distance apart, the two sprocket wheels 18. 1 9, and the shaft 17 having mounted thereon

similar sprockets

19, 19. ltunnin over the sprockets 18, it), are the two chains 20. 20, each carrying a belt 21 and on each of said hells ll there is mounted a projection 22 \\'lllt.lt each time the hell. revolves comes into engagement. with the rear end of the lowermost. sheet in the pile and pushes it forward out of the hopper and onto the belts 23, whence it is fed forward to the registering 1f thin sheets of paper are to he the sheets onto the belt. Tiere are well known means for doing this. It is not deemed necessary to describe them, BBthlB preliminary feed from the hopper does noteon-titute the present invention. 'l'hc tallli' it is formed with sl ts or openings 2t through which the sprocket chain and hell project from lieneatli. so that the pro'cetion 22 can engage with the hlaiili. it is o I\'it'l\lS that instead of having the projection 23:! mounted on a helt 21 carried hy the chain 2". the projection .22 may he carried directly hy the chain and the hell 21 he disensed with.

The eleetrotype plate 25 is siiitahly mounted upon the cylinder 26. said eleetrotype plate being cast of suitable shape. so as to conform to the curvature of the periphery of the cylinder. The cylinder .26 is mounted on shaft 27 which is driven hy any siiitiihle means. Mounted on shaft 28 is a cylinder 20 which has a vulcanized ruhher blanket flfl. somewhat yielding. which eot'iperates with the c \'linder 2G and serves as an iiiipies ion cylinder. The cylinder 26 is provided with teed rings 81 which are pret'erahly slightly greater in thickness than the thickness of the electrotype plate and which enea e the periphery of the rubber hlanket 30 o the cylinder 20. Preterahly the feed rings 31 have a coating of ruhber so that there will he riihher engaging with both faces of the card and prevent slipping. It is im ortant that these rings 31 should he i'emova ile ah well as adjustable longitudinally of the cylinder, so that the eleetrotype plate may he slipped on and oil endwise and at the same time the with relation to the cylinder 26 although they are carried by and rotate with the cylindcr 26. The means shown are as follows: The rin 31 are formed with beveled edges till. Tie cylinder 26 is formed with a series of longitudinal grooves 512 in the periphcry, said rooves being T-shaped in crossseetion. -sliaped bolts 33 are provided which ean he engaged in said grooves 32 hi! 'ted forward to be en inserting them into the end of the groove, being termed with a foot 3 31 which engages ith the lower, wider ortion of th roove. Ciamp disks each ave a beveled flange which engages with one of the beveled sides 311 of the ring and is clamped thereon b\' a screw 34 which screws into the bolt When the rings are slipped onto the cylindcr 26 and are adjusted to the desired posi- .tion, the bolts 33 can he slid along in the {grooves 32 to the proper position for the [hinge of the disk 35 to engage the ring: and the screw 34 will then he tightened to clamp i the disk to the ring. I The card which has been pushed from the hottom of the pile in tho'hopper and carried In; the chain 20 onto the belts 23. has to he aged by nnd passed at 26 and the impresdoinp; this between the type cylin lBiOl'l cylinder 29.

The means for and for properly timing the feed of the ca rd i sn that it will pass lit-tween the cylinders at the right time with relation to the position lot the elertrotype plate will now he dei st'rihell. 1 Each of the hells 23 runs over a pulley fl l on the shaft. 1t: and over a pulley .17 on the Esliat't IlS.

$iiid shaft 8 has driving con- V ttttli tl with the shaft Hill It sprocket chain eages witi a gear 42 mounted on stud 43.

Said gear -l'2 engages with a pinion mounted on shaft. 33. Thus h) t 10 several -gears a iid sprockets the printing cylinder shaft 2i controls and drives the mechanism i which withdraws the card from the hopper and also drives the halts 23. A fler the sheet rat-d to teed it still further forward and this gripping and t'eethnp; mechanism comprises two pairs 01' gm iping rolls 45 and to. lrct- I l 1 1 "fi'itti ltt'. other teed mechanism grips the llttlJ v these re ls hare ruhher covered pel ot' eardhoiird has heeii carried forward by the lu'lls 211 int proximity to the printing,

ripheries. The gripping rolls 45 are mounted on shaft 38 and the gripping rolls 46 are mounted on shaft 47. aid shaft 47 is journaled in the rearward arms of levers 48 which are fulcrumed on studs 49 so that said shaft 47 may be raised and lowered by turning the said levers on their fulcrulns, there by moving the gripping rolls 46 toward and from the rolls 45. Mounted on shaft 38 is a gear 64 which is adapted to engage with a gear 65 on shaft 47 whereby the rotation of shaft 38 will rotate shaft 4!. The forward arm of each lever 48 carries a friction roller 50 which engages with a cam 51 mounted on shaft 27. A spring 52 keeps the roller 50 in constant engagement with vthe cam 51. When the high part of the cams 51 engage the roller 50, the levers 48 are turned on their fulcrums so as to lower the rolls 46 so that they press the card 12 against the rolls 45 causing the card 12 to feed forward. l/Vhen the rollers 50 ride off of the high part of the cam 51 the gear 65 will be raised slightly although not enough to entirely disengage the teeth, but enough so that the rollers 46 will be lifted out of engagement with the card 12 and cease the feeding action. the gears still revolving. The card 12 is fed forward between the gripping rolls 45. 46, by the belts 23 during the period while said rolls 45, 46, are separated from each other. When the card is fed forward by the belts 23 it is desired to have them always stop in a certain position ready to be taken up by the gripping feed rolls 45, 46. Above the path of the card are brackets 62 from each of which a pin 55 projects down nearly to the table 11 with suflicient clearance for the card to pass under it when the card is fiat on the table. Mounted on a rockshaft 53 is a lever 54, said lever 54 and rockshaft being normally held by a spring 56 with the lever turned up so that the sprin 58 hereinafter referred to will be elevate slightly above the curled up end of the card 12 as shown in Fig. 1. .When the forward end of the card is curled up, as-shown in Fig. 1, it will engage the pin 55 which thereby stops the forward progress of the card 12 until it is released from the pin. Means are provided for giving to the forward end of the card an upward incline to engage said stop pin 55. The means shown consists of a sli ht hump 66 with sloping back and front which gives to the forward end of the card in its forward feed an upward slant so that it enga es the stop pin 55, as shown in Fig. 1.

rojectin from the end of the cylinder 26 is a pin 5 which at a certain point in the rotation of the cylinder engages with the up er side of the lever 54 near the forward en causin it to turn down and rock the shaft 53. ecured to the under side of brackets 63, which are fast to rockshaft 53, are springs 58 the forward end of each of without interference.

which is free and bends downwardly and is adapted to engage the curled up forward portion of the card 12. When the said lever 54 is turned down by the pin 57, the rockshaft 53 wilt be turned, thereby carrying down the free end of the spring 58 which thereby flattens down the curled up forward portion of the card 12 so that it will be enabled to pass under the pin 55 when the card 12 is fed forward. The pin 57 is so located with relation to the high part of the cam 51 that the lever 54 will be turned so as to flatning guide and is one of the main features of the invention. The means shown is as follows: Secured to the peripheryof the impression roll 29 are clips 59 pointing backward and with which the forward end of the card 12 is adapted to engage. These clips 59 may be secured to the impression cylinder in any suitable manner. The means shown is T-shaped bolts 60 which engage with a T-groove 61 in the; periphery of the impression cylinder and the clips are secured to the bolts in somewhat similar manner as the disks 35 which clamp the rings 31 are secured to the type cylinder. The gears which drive the gripping

rolls

45 and 46 are of such diameter with relation to the driving gears for the type cylinder that the'surface speed of the grlppin rolls 45,

ido

46, will be a little in excess of t e surface 7 speed of the type cylinder and of the impression cylinder, so that when the card 12 is fed forward by the

rolls

45, 46, it will catch up with the clips 59 which are moving inthe same direction as the card 12 and cause the card 12 to engage in the under side i of. the clip as shown in Fig. 3. The thickness of the rings 31 allows suflicient clearance between the periphery of the cylinder 26 and of the impression cylinder to allow the clips 59 to go through in the rotation As soon as the card has entered between the type cylinder and the impression cylinder it will be gripped by the rings 31 and impression cylinder 30 so that the card will be fed forward after it is released from the grip ing rolls 45, 46. The adjustment is such t at the gripping rolls 45, 46, will release the card just as soon as the feed rings 31 and the impression cylinder grip it. The flexible surface of the imipression cylinder blanket 30 will yield su eiently under the pressure of the rings the surface of the card and give the proper printing impression. After the clip has ridden past the center it will ride away* from and release the card so that the card 1 may travel free from the clip and be thrown 1 oil or carried away in any suitable manner. The speed of the clip 22 which pushes out the card from the pile should be timed so as Q to push out one card at each rotation of the I type cylinder.

It is obvious that the cam 51 might be carried by the impression cylinder shaft instead of by the type cylinder shaft and also that the means for operating the gripping

rolls

45 and 46 might be varied without departing from the invention, and also that the entire mechanism for feeding the card so that it will enga e with the running uide 59 may be varie and still come within the scope of the invention.
