My invention relates to an improved deliveijv-me hanisni for cylinder printing )resses of the.tv in which the )rinted sheet is delivered to the delivery-mechanism from a point toward the top and. in front of the impression-or]inder. the objectof my present invention being to provide simple. convenient and reliable deliveryineohanism eonvertihle tor delivering the sheets printed side up or printed side down. and for delivering the sheets printed side up from the tapes with the tape-roll slide in an extended position and the tapes con tinuously driven.

lVith these ends in view my invention eonsists ina delivery-mechanism having certain details of construction and combinations of parts as will he hereinafter described and pointed out in the claims.

I have chosen to illustrate 1n i present im proved delivery-mechanism as embodied in a fiat-bed. cylinder press. but Twould have it. understood that my invention is equally well adapted. for on'ihodin'ient .in a rotary press. Moreover, as tlat-hed, cylinder presses are well known as to their construction and operation, it has seemed unnecessary for me at. this time to. illustrate or describe such a press in detail.

As herein shown. the -impression-eylinder 9 s, drivenas usual by a large gear 3. For

continuously driving the tapes 4 \vhieh receive the printed sheets from the said cylinder at a point to 'ard the top thereof and in front thereof. employ a pinion meshing upon the outer end of a sleeve 6 turning upon a stud 7 mounted in the frame 8 of the deliverymechanism. At its inner end the sleeve 6 carries a gear 9 meshing into a pinion 10 having a eollarll to which is fastenedadisk 19. carrying a pawl 13 having a handle 13 and engaging with a rattihet-wheel 14 fixed to the outer end of the shaft 15 of the main taporoll it. One end of the shaft 15 projects through a portion of the frame 8 aforesaid, its opposite end being journaled in a corresponding parallel portion thereof. The main tape-roll 16 drives the tapes 4- which are spaced apart for the location between the in. of the fly-fingers 1.7 which are mounted upon an oscillating fly-shaft 1'8 the ends of which are entered into bearing-heads 19 mounted upon the upper ends of vertically. movable rack-rods 20 supported in brackets 21 fastened to uprights of the frame 8. By

raising and lowering the rack-rods 20, the .tly-fingers 17are bodily raised above and lowered below the plane of the said tapes 4: according as it may be desired to deliver the sheets printed. side down or printed ide up.

For delivering the sheets printed side down,

the fly-fingers 17 are lowered below the plane of the tapes'end oscillated by rocking the shaft 18 aforesaid; while for deliveringthe sheet printed side up, the fly-fingers are. raised above the plane of the tapes and 211 lowedto remain at rest and so act as overguides for the printed sheets.

The two rods 20 are formed with vertical racks .22 respectively meshed into by pinions 23 mounted on the ends of a rock-shaft 24 iournaled in the frame Sand. provided at the other hand, by depressing the lever so as to enter its lug 26 into the lower notch 27, the rack rods 20 will be sufiiciently elevated tb'oarry the fly-fingers 17 above the tapes l *Zt'or the delivery of the sheets printed side up.

Preparatory to moving the lever QS-from its elevated to its depressed position and vice, versa, the-loelnng-lever 29 must be manually swung outward away from 1t so as to clear the locking-lug 26 from the notch 27 at the tilneentered'by the said lug. Now

to' prerent the said lever 99 from being -,.,=swung outward as described, except when the parts of the delivery-mechanism are properly positioned for their com'e'rsionfrom one mode of delivery to the otheqthe said lever is provided w th two outwardly projectingjustifying-pins (the term seems appropriate) 30-for entrance into justifying holes 3-]. formed in the flat inner face-of a rack-case 32 fnlc'rur'ned at its lower end upona stud 33 in the side frame34 of the press and receiving the tape-rack 35and the flyrack 36, Whichnre' placed edge to edge in the said case and reciprocated independently of each other as will be described later on. Theinner faces of these racks are formed with justifying recesses 37 located so that when brought into registration with the holes 31 and the pins 30, the several parts of the delivery merhanisn'i are suitably positioned for its conversion for delivering the sheets printed side up or printed side down. Only when the justifying recesses 37 have been brought into registration with the pins- 30 can the locking-lever 29 be swung outward so as to release the converting lever 25 and permit the same to be lowered or raised as may be required for delivering the sheets printed side up or printed side'down. The

pins 30 thereforev confine the operation of the converting lever to the time when the conversion may properly be made. I After the conversion of the mechanism has been offected. the lever 29 is swung inward whereby the pins 30 are cleared from the rec asses 37 in the racks 35-and 36 and the lockingdug entered into one or' the other of the two.

notches 27.

The tape-rack 35 is reciprocated in the rack-case 32 by means of a connecting-rod 38 having its upper end 'pivota lly connected with the said rack near the lower end thereof. and having its lower end pivotally connected with the fly cam 39, so called, which is mounted upon the cam-shaft 40,the cam 39 forming what amounts to a crank commotion between the rod 38 and the shaft 40. I y

The-fiy-rack 3G is reciprocated in the rackc-asc-32-by a connecting-rod 41 pirotally con- 'lUC nccted'with it and having-its lower end pivotally connected 'withf the upper end of a curved fly-can'i lever 4-9 fulcrumed upon a stud 4.3 and carrying a cam-roller 44 pressed against the edge of ,the fly-cam 39 by a.

spring as acting through a rod 46 pivotally connected with. the said lever 42 and mom'itedin a bracket 4-7attached to the side frame 34.

For cutting out the reciprocation of the fiyrack 36, T provide a latch 48 having a handle 49 and a throat 50, and pivotally mounted upon the end of a bracket- 51 secured to the side frame 34.. dVhen this latch :48 is swungorcr into the position shown bl broken lines in Fig. 1, its throat 50 engages with the upper .eud of'thc fly-rain lever 42 -.'and holds *the same from being. operated by -the fly' cain The sa1d'tape-rack 3.5 has its lower faeetoothed forfengagement with a tape-rack pinion-53, while the said fly-rack 6 has its upper face toothed for engages inent with a fly-rack pinion 54, the rack 35 being interl'neshed with the pinion 53, oritherack 36 being intermeshed W'Iil'l the pinion 54 according as the rack-case 32is swung up or down on 1tsstud for which purpose the. converting-lever 25' is provided, as

of the tapes due to the rcciprocation of the from the ratchet-wheel 14-, thus cutting out to, but. eccentric with the shaft '24 upon *iposi tion, the press will. be converted for delivering the sheets printed side down and verted for delivering the sheets prii'ited side "lUCill'tt'l upon opposite sides of the delivery lHGClIHDISIH. and provided with rollersnfi whcrchy the tape-roll it; and the tape-wheels -1(3 and (it) as shown in Fig. 4, and the length shown, at its extreme lower end with a stud 55, the opposite faces of which engage with the opposite walls of a segmental slot 56 formed in the rack-case 32 at a point close which the said lever 25 turns as upon a center. ll-"hen the lever 25 is in its elevated the stud will be located at the lower end of the segmental slot 56 as shown in Fig. 10.

The taperack pinion mounted upon a. stud 59 (Fig. 2) also earrying a wheel 60 which meshes into a wheel ll 'mountcd upon the outer end of a shaft 62 carrying two wheels 62-5 3) I'QSINCtlVtElY cngagirg with horizontal racks (it formed in the lower edges of horizontal. slide bars 6.")

aforesaid is traveling upon portions of the frame 8 thereof. In the slide-bars (35 I journal the tape-roll (i6 and a shaft (lTpwhich latter carries a'series of tapewvheels 68 employed in place of a roll to permit the fly-fingers 17 to be arranged .hetween the tapes 4 which also pass over a fixed tape-roll 9 the ends'ot which are jonrnalcd in the frame 8. The side-bars (35 form the tape-roll slide which is-moved hack and forth for the extension and contraction of the tapes 4. in the Well known manner. and which. when so operated, drives thetapes. "hen the tape-rack 35 moves downward, it moves the tape-roll slide outward, wherchy the tape roll ll and the tapewhecls 38 are moved outward with the effect of virtually doubling the upper or sheet-receiving reaches of the tapes so as to provide room for the delivery of the printed sheets printcdsidc up. from the impression cylinder upon thc tapes which by their own traveling motion at this time deliver the printed sheets for final delivery. ()n the other hand, when the ta. ')e-rack 35 moves upward. it moves the tape-roll slide inward,

(38 are doubled, so to speak, on the tapea'olls of the upper or sheet-receiving reaches of ll'hen the press is converted for delivering the sheets printed side up by the propulsion tape-roll slide,-the pawhli-E is disengaged the power of the impression cylinder 2 from moves inward. the upper reaches the tapes 4, and leavingthem to he propelled by the reciprocation'of the tape-roll slide.

'Inorder that there may be no reverse rotation of the tapes 4 during the inward eX cnrsion of the tape-roll slide, I employ pawls 70 respectively engaging with a ratchet wheel 71 secured to one end of. the tape-roll If), and with a ratchet-wheel 72 secured to one end of the shaft (37 carrying the tapewheels 68.

The propulsion of the tapes during the outward movement of the tape-roll slide, by the slide itself. may be explained as'follows :As the slide stai'ts upon its outward excursion the pawl 70 of the ratclict-w-l'iecl '72 engages with the same and prevents the rotation of the shaft 37 carrying the tapewhecls (38 which are thus held against rotation, while, on the other hand. the ratchetwheel 71 is free to rotate under its panl 70, thus leaving the main tape-roll it] free to revolve. Itfollows from this that the endless tapes are virtually fastened to the ta pcwhccls (38 during the outward movement of the slide. whcrchy thc lapcs arc drawn. as it wcrc. over thc frccl running main tape-roll 1t) and the roll (it); 'lln-rcforc during the outward cxcursion of thc tape-roll slide each tape is longitudinally propelled or drawn fo a distance retnfcscntcdhv ahout half of its entire length. ()n the other hand at the beginning of thc inward excursion of the slide. tllc situation with rcgard lo the pawls and l':Il('l1('l-\\llP(-l5 aforesaid is reversed, the i I ratchet-wheel T2 turning freely under its pawl 70. leaving the tapc-whcels 8 free to run. while the ratchet-wheel Tl is engaged by the other pawl '70, whcrchy the main tape-roll '16 is held against rotation. This. prevents the reverse propulsion of the tapes which are never permitted to move in the opposite direction from the arrow shown -on' Fig. 4. During the inward movement of the slide, the lowcr rcaches of the tapes are doubled on tkcnnclves, so to speak, but there is no .lzmgitudinal movement of the upper rcacla's of the tapes. However-i as the'slide of the tapes are virtually pcclcd from under the lower face of the printed sheet which is left. free to drop when this peeling from nndcr op eration is completed.

To reduce the speed at which the sheet is finally delivered by TlIPltIIH' l. I employ a s iced-reducing roll 73 mounted in brackets 7-l ccur cd to and projecting beyond the outer ends of tho slide-liars (l5. thc roll Til hcinig' lri\cn hy a'hclt 75 running over a pulley if? locatcd at one end of the shaft 13?.

whcrchy the spced'reducing roll '73 travels at a slower ratc than the tapes -t. series of whccls 77 mounted upon a shaft 78 press the sheets down upon-the said roll ill' thc shaft 78 being mounted in the outer cn lof arms 79 hung in hi'ackcts St) extcmling plit! ' pressioncylinder 2 for which purpose the pawl 13 carried by the disk 12 is thrown by its handle \13 into engagement with the ratchet-wheel 14 mounted on the shaft 15 of the tape-roll 16, whereby the tape-roll 16 partakes of the continuous movement imparted to the disk 12 through the gears 5, 9

and 10, the former meshing into the cylinder gear 3. r 'i In case it is desired to operate the press for the. delivery of the sheets printed side up, without the reciprocation of the tape roll slide but with the same in any desired position within the limits of its reciprocation the press is turned over so to. speak, until the tape-roll slide has been brought into the required position. The connecting rod 38 is then disconnected with the fly-cam 39 by the operation of the locking-slide 81 at the lower end of the said rod 38 which then swings down into the position in which it isshown in broken lines in Fig. 1. The pawl 13 is now thrown into engagement with the ratchet 14, thus providing for the continuous movement of the tapes l at the speed of the impression cylinder As shown, the press is furnished with a delivery-board 89 having the usual joggerboard 83 and front stops 84-, this board 82 being supported upon a batten 85 in turn supported by a rod 86 of usual form,

In case it is desired to deliver the printed matter into or upon a receptacle 87 (Fig. 8) beyond the delivery-board 82, the tape-roll slide will be moved to the limit of its outward excursion after which the rod 38 will be disconnected itromthe cam 39 as just eX- plained. The pawl 13 will then be thrown into the ratchet 14:. so that the tapes 4 will be continuously driven. The printed -mattcrwill then be delivered into the receptacle 8? from the tapes.

For vibrating the jogger-board 83, I connect the same by a strap 100, with an arm 102 mounted upon -a jogger-shaftv 88 provided at one end with a joggerhead 89' carrying sctscrews 90 and 91 respectively engaged by the ends of ogger-levers 92 and 93 loosely hung upon a stud 94:. The said lever 92-has a downwardly extending arm 95' carrying a roller 96 entering a cam-slot 97 in the fly-rack 3G. wlnle 'the lever 93 has an upwardly extend ng arm 98 carrying a roller 99 entering a cam-slot 100 in the tape As the saidracks and 36 are rack 35. reciprocatcd, the inclined walls of the camslots 97 and 100 turnthe levers 92 and 93 upon the stud 44, and this movement is transmitted through the joggeuhead 89 to the jogger-shaft 88, and thence to the jogger-board 83. The above mechanism moves the jogger-board 83in the direction of the arrow on Fig. 16, the jogger-board being moved in the opposite direction ,by means of a spring 103 located below the deliveryboard 82 and connected with the lower edge of the jogger-board so as-to act in line with the movement thereof.
