T0 all whom it may concern:

Be 'it known that I, GEORGE a citizen of the United States, anda resident of New London, in the county of New London and State of Connecticut, have invented a certain new and useful Sheet-Delivery' Device :tor Printin '-Presses, of which the following isa speci cation.

My invention relates to a mechanism fori delivering'sheets from the. impression cylinder of a printing press upon a deliveryf board, either printed side up or printed side down. Devices have been in' usel for .delivering `the sheets printed side up; and others have been in use for delivering printed side down; but my present invention embodiesa deviceJ by which either of these operations may be performed on the same press as requirements demand.l

The principal object of my invention is to provide a combined delivery in which all of the principal advantages of the most approved printed side up,- as well as printed,

side down devices may be retained and utilized.

Another object of my invention is to provide a combined arrangement in which the change from one kind f delivery to the other may be effected in a simple and eiicient manner and with the aid of means which are mechanically eiiicient.. vAnother object of my invention is to employ tapes in the printed side down or iiy the ily-lingers in elevation, Fig. 5 is adiadelivery device which may also be utilized to keep the sheets upon the tapes of the printed side up delivery device.

Another object of my invention is to provide an arrangement in which the changev from onel kind oi' delivery to the other may be .effected without altering the location of Another ob'ect oitl my invention is to make it `not only simple manner,`but to provide`an arrangement wherein the possibility of'interference v from impro er manipulationl is avoided. Another'o ]ect of my 1nvent1on 1s to provide anarrangement wherein "the shifting of some of the parts'necessary to the change f fromv one delivery to the other will be ef# P. FENNER,

,gears possible'. 'to eifect the change from one dellvery to thejother, inaj very 'vide effective means for. stationarily holding the Afiy lingers out of operative position While tlie mechanism is being used for delivering sheets printed up. Another .object of my invention is to pro- .vide simple and effective means 'for throwing out of operation those parts ofthe complete mechanism which do 'not take part in .the operations during the delivery of` the sheets 'printed side up or printed side down. Another object of my invention is to make `the tapes of the fly device reversible in their .operation so that they may be utilized when either form of delivery is in operation. Another object is to make the reversal of ,these tapes effective automatically as the shift is made in the parts from one 'form of -delivery to the other. f Another objectief myv invention is`to 'arrange for the shifting 'of the position of the tapes of the delivery devices, from either side ofthe machine. t

Other advantagesderived from my invention will be set forth in the-detailed description hereinafter. f r

,I have shown the stationary frame 1 of a.

flat bed printing press of ordinary construction, having standards 2 for supporting the 'impressioncylinder 3; and the standards 4 for supporting the sheet deliveryA mechanisms. It is to be understood that the press l5 may be of any ordinary or special construction as my present invention necessitates' no changes in the construction of the press proper. The printed sheets are received from the impression cylinder lirst upon the zoguide'fingers 5 from which they pass between the cutter rollers 6, 7, driven in the -usual manner; and from these the sheets pass onto the sheet delivery device to be delivered either printed side up or printed side down, according tothe positioning of the parts hereinafter described. There may be cutter rollers G, 7 arranged upon the shafts 8, 9, for engaging the margins of the sheets and there may be intermediate cutter rollers 3e for engaging the middleof the sheet if clesired, according to present practice.

JThat branch of the mechanism which delivers the sheets printed side up consis of the following: The-re. are supporting. tracksI I larv clutch device 31 on the shaft 25 of the 10g pulley 27 for preventing this pulley from l turning right hand, and for permitting it or rails 10, 11 arranged. at each side of the press, and they extend from a point near the impression cylinder to and over the delivery boardv1`2'.` The tracks 10 are preferably sta.- tionary; whiley the tracks 11 are stationary dur-ingthe operation of the machine, but

they may be 'racked backwardly and away.:

from the cylinder tofold in relation to the tracks 10;' for the purpose of providing easy access to the impression cylinder and asso- V ciated-parts. There is a shaft 13 journaled in the side frames of the machine, which shaft is provided with an .operating crank A 14; and gears 15 near each end of the shaft ,meshwith the rack teeth 16 on the undersidesgof the tracks 11.v This feature of a folding track is not, per se, new in the present case, as it is shown and described in my said Patent No. 604,974. The carriage for delivering the sheets upon the delivery board is reciprocatable along the tracks A10, 11.`

The carriage consists, primarily, of the rails 17, 18, having flanged wheels 19 secured near one end and traveling on the track rails 10; and having other flanged wheels 20 traveling on the track rails 11. By means of the tracks andthe wheels the carriage is supportedand guided in its reciprocations from a position near the impression cylinder to va position over the delivery board. There is a shaft 21 near the impression cylinder which has a tape pulley 22' over lwhich travel the endless tapes 23 of the printed side up device, there being a number of these tapes arranged side by side inthe same plane across the machined" The pulley 22 is not 70 movable with the delivery carriage although it-is shiftable in position, as will be later pointed out. There is a shaft 24 near the other end of the device that is,vover the carriage; and this shaft carries the pulley 25 over which the tapes 23 also engage. IThis pulley, 25, is also stationary as to the travel of the carriage. The carriage itself has a lshaft 26 near its front end, which carries 80 another tape pulley 27 which travels with the carriage and above the pulley 25. The tapes 23 engage around this pulley 27. There is another shaft 28 and pulley 29 arranged near the rear end of the movable carriage; which travel with' the carriage, and ina horizontal plane, between the planes Y of the pulleys'27 andv 25; since they are to pass between the latter. The endless tapes 23 pass from the pulley 22 to the pulley 27, 90 this por ion forming the active or sheet holding runs of the` tapes; fromA the pulley 27 they pass to the pulley 29; vfrom the latter to vthe rear stationary, pulley 25; and from the latter, rear to the pulleyv 22; Upon g5 the hshaft 21 there is arranged a clutch device 30 for permitting the pulley 22 to `turn 2 left hand in Fig. 5, and for preventing it from turning right hand. There is a sinnto turn left hand, in Fig. 5. The pulleys 221` 27, therefore, both to the left but cannot turn to the right; but'. thev 'clutches 3) 10.5v

and 31 niaylae c'i'ective-v at diffe-rent times,

as will be made appareuat-u When themov able carriage is approachingl its rear posi. tion near 'the impression eyllinder, the sheet from the impression cylinderis fed out be? tween the cutter rollers 6, 7, and over the pulley 22 uponthe upper run of 'the tapes 23; and during the'time the carriage is` moving forwardly away from the impression cylinder the sheet is deposited full v length upon the tapes. When the carriage is moved to the left in Figs. 3 and 4, for

the purpose of carrying a previously deposited sheet over-the delivery board, the pulleyA 27 lmoves away from the pulley 22; and 120:

the pulley 29 moves toward the pulley25. The separation of the pulleys 27 and 22 will cause them to draw in opposite directions y upon the upper lrun of the tapes 28 ;l and the Looenlf tended in length, the sheet traveling forwardly with' the tapes. Duringthis forward movement ot the carriage the pulley 29,is moving toward' thepulley 25; and',

consequently, the run 32,. of the tapes is shortening to the same extent that lthe upper run 34 is .'being extended. The pulleys change their relative positions to lengthen thel upper-run of the tapes so that these extend, when the carriage has reached its ex- Ytreme forwardposition, fromthe pulley 22 to the front end of the delivery board.

During this movement of the carriage, the sheet previously deposited upon the tapes is 'carried forwardly, therewith, and vwith the carriage,l to a \position over the delivery board'. When the carriage vis, reversed 1n d1- rect-ion and moves backwardly toward the impression cylinder again a different action takes place. In this movement, the rearwardly moving pulley29`must extend the run 32, of the tapes and to do so must take the tapes from `another run.' Since the clutch 30 only permit-s the pulley 22 to turn left hand, the extensi \n of the run 32 must be made by leaving the upper run stationary relative to the carriage and by taking up part of it for the extension of the run 32.

g vIn this operation the tapes peel`oft `under the sheet which has been positioned over the delivery board;- and,y as `the carriage simultaneously movesrearwardly, the sheet is 'deposited upon the delivery board,

printed side up. During the `forward movement of the carriage a sheet feeds through the. cutter rollers and upon the tapes and ,Y behind a previously deposited sheet, ready to be 'carried forward to the delivery board.

These operations are periodically repeated so long as the printed side-up device is 1n operation. i

The clutches for controlling the shafts 21, 26 are shown in Fig. 9. Each consists of a disk 35 keyed to the respective shaft; and of a ring or cage 36 partially -inclosing it. The disk 35 has the ball races 37, in which lie the balls 38. Springs 39 acting on these balls tend to move them intoa posit-ion which will cause them to impinge between the disk 35v and4 the cage 36. A pin 40 on an extension of the cage, engagesA parts relatively to which the respective shafts revolve.` In the case or" the clutch 3() the pin engages a handle 42; whereas the -pin of the clutch device 31 engages the rail moved along the races 37` which causes them to impinge between the disk and the cage similar gears 44, arranged near opposite sides of t-he machine; and upon the same shaft there is a gear45. A casting 46 is held upon this shaft; and it' forms a housing for the gear 45 and a bearing for the sliding rod 47. The upper-,end of this rod 47, has rack teeth 48 which mesh with t-he teeth `of gear 45; so that' when the rod is reciprocated the gear and its shaft are oscillated. .The gears 44 mesh, respectively, with similar gears 49 mounted upon the studs 50. These latter gears, in turn, mesh. with the rack. `teeth 5l on the under sides of the rails 17, 18, of the reciprocating carriage. From the 'above it will be 'apparent that the reciprocat-ions of the rod "47 cause the oscillation of the gears-45 and 49 and through these, the reciprocation of the carriage.

In Figs. 3, 16 and 17 I have shown the device `for 'disconnecting t-he carriage and for. holding it out of operation. The rod 47 has an open hook 109 which engages a pin on the crank arm 111, which issecured upon the shaft 91. When the carriage is to be'thrown ut of operationthe hook 109 is disengaged from the pin 110 and the rod is raised into position to be held by a supporting device. The latter comprises a pin 112 xed in the side frame of the press and provided with a rocking portion 113 hinged at 114 in Vsuch a manner as to be movable upwardly but not below the horizontal. The member 113 is swung upwardly into the dottedV line position' of -F ig. 16 to allow the rod 47 to pass it; and nwhen this has been done the pin 113 is lowered to the horizontal position to support the rod. The carriage may be moved by hand, up close to the impression cylinder, with the rodl 47 sliding on the pin 113, until the hook 109 engages the pin. The carriage will then be iirmly held in position while the fly delivery is in use. This forms a very convenient arrangement for positioning and locking the carriage. There is a washer 115 ar- .ranged upon thepin 113.4 When it is desired to rack back the tracks 11 by operating the crank 14, .the rod 47 is first raised above the pin 113 in the manner just described and the rod is allowed to rest upon the washer.- As the tracks and carriage are racked backwardly the rod 47 rests upon the freely revolving washer., This arrangement makes 1t unnecessary for a attendant I1aled=in the similar lever arms 52 which arms 52 for rocking the levers to place the\ to hold up the rod 47 during thel racking back'of the track and carriage.

The cam 90 is secured to a portion of the' crank arm 111 by means of a b0lt116, which is adjustable along the slot 117. To adjust the fly delivery for different sizesheets itis simply necessary to loosen the bolt 116, adjust the position of the cam on the shaft and tighten the bolt again. If small sheets are being printedlthe cam will be adjusted to make the fly fingers advance so-oner in relation `to' the printing operation so that the sheet will becarried .over as soon as it isentirely over thely fingers; whereas when `larger\"-sheets are being printed the reverse adjustment of t-he cam is made to delay the throw of the fly -lingers sufliciently to allow them to receive the larger sheets.

The shaft 21 which carries the forward and non-traveling tape pulley 22 is jourfulcrumupon studs 53 secured lin the tracks 11. There is a handle42-on each. of vthe shaft 21 and its pulley, in either an upper or lower position. The parts are'secured ineither of these positions by means of a bolt 54 passing through apertures in the rails and through either-of the apertures in levers 52 which support the shaft 21. When the pulley 22 is .placed in its higher position the bolts 54 are engaged in the higher apertures 55 to firmly hold it in position; and when the pulley is to .be placed in its lower position the bolt is removed, the pulley lowered, and the bolts are entered.

in the lower apertures ,55 to firmly hold the Pune-V in POSOn. 17V-hen the pulleyis placedin the upper position, as shown in Fig. 11, the tapes 23 are in positionto receive on their upper runs 34 the sheets fed through the cutter rollers: Tjhis isl the case when the printed side up delivery is in operation. When the pulley 22 is placed in its lower position the tapes 23 will'be below the receiving position and will per/form no function in the delivery bf the sheets.\

The fly device for delivering printed sidel do-wn is arranged as follows :-The fly fingers and operating parts are preferably mounted on the stationary parts .of the machine so that they need not\partake of the reciprocations of the carriagel Inthe upper arms of the adjustable levers 56 there is journaled a shaft 57 which carries any de sired number of tape pulleys58.l There isa shaft 59 movable up and'down in afslotted journal (l0 vne`ar the rear, end.of` the device, vpreferably over the shaft 21. This shaft 59, carries tape vpulleys 61, corresponding 'in numbers and positions`with the pulleys on the shaft 57. There are endless tapes G2 engaging over the pulleys 58 and 61. These tapes lie above the tapes 23. They serve to .receive the printed sheets from the cutter shaft 59.

rollers when the device is' operated to deliver printed side down; and they coperate in this respect with the liy fingers, the latter being adapted to take the sheets from the tapes, as will appear. The tapes 62, in addition to serving as part ofthe fly, co'v operate with the tapes 23 of the printed side down delivery to prevent the sheets from blowing up from the latter tapes.

There 'is a large gear 63 on the impression cylinder', which drives an intermediate gear.

frietionally by the lower rollers 7 The gear also drives a gear v67 mounted uponla shaft 68 in the bracket G9. This latter gear is adapted to drive the tapes 62 when the printed side vdown delivery is in operation; but when 'the printed side up delivery is `in operationethese tapes are driven 1n a reversedirection. llVhenl the shaft 59 is 1n its lower `\-.positi'on the gears 70 carried thereon are in" mesh with the gears 67 and are driven bythem. At such times the tapes 62 are operated so that their upper runs travel au -y from the impression cylinder in the direction necessary to carry away the sheets. At such' times, the shaft 21 is idle because the `carriage is not then driven.

dien the shaft. 21 is in its higher position, as when the printed side up delivery is in operation, the gears 70 of the shaft 59 and -the gears 71 of the shaft 21v are inI mesh;

andthe gears 70 and G7 are' out of mesh. At such times, therefore, the shaft .59 is no longer driven fromY the impression cylinder, but is driven from the shaft 21. At such times the shaft 21 is intermittently driven through the action of the reciprocating carriage and -the advancing of the'tapes 23, previously described;

Frein the above it is apparent that when the printed side .down'of fly. delivery is in operation the shaft 21 and thetapes 23 remain idle; and the shaft 59, driven from the impression cylinder, eauses the tapes 62 to travel in the direction indicated by the arrows in Fig. 7. Whenthe printed side up 4delivery is in operation the lower runs of the tap-es G2 travel tothe left` in the' drawings whereas, when the shaft 59 is operatedv from the' impressionv cylinder, as in delivering irinted side down, the upper runs ofthese tapes travel to the left.` The shifting of the shaft 21 to alterthe position of the tape pulley 22 simultaneously shifts the shaftv 59 and ch anges its drive. :On the shaft 21 there are rollers 7 2. in line with rollers 73 on the `When either of the handles`42 is operated to raise the pulley 22 from the lindividually taut under a`ll conditions.

underproper tension at all times. The ad' justment of the tapes 23 laterally of the machine to adapt them to the dierent sheets is facilitated by the above arrangement. Then the tapes are shifted, the yokes `105 and connected parts are simply slid along their bar 104 Ato any desiredposition.

Operation: To operate the devicefor delivering printed, side up the parts should be arranged as follows: The fly fingers 'ifi' are held in the position shown in Figs! 3 and 4 by the bolts 80 engaging in the apertures in the fly shaft; the shaft 76 is disconnected from the gear 85; and the roller S9 is held olf the cam 90 by the Vaction of the eccentric on the lever 87. In this condition the fly fingers can not operate. The tapes and their various pulleys will be positioned as shown in Figs. 8, 4, 10 and 11. The pulley 22 will be in its upper position, so that the upper runs of the tapes 23 will be in position to receive thereon the printed sheets as they come from the cutter rollers. The shaft 59 and its pulley 61 will be in ltheir higher position, being held up. by therollers 72, 73, which also hold the shafts 21 and 59 separated sufficiently to space'the tapes 28,:62 to allow the sheets to pass freely between them. In this position of the shaft 59 and its pulley, the Ilower runs of the tapes 62 will lie just above the upper runs of the tapes 23. Inv

this position of the parts the gear .71 will operate upon the gear to drive the pulley 61 and its tapes. The latter will be so operated that their lower runs will travel' change to the iiy deliveryithe following changes will be .madez The rod '47 will be disconnected from the arm on the main shaft and it Awill be connected with the lpin so thatA the carriage will no longerjreciprocatejbnt will be held up. close toward the impression ,I

cylinder. The bolt 80 will be taken out of apertures in the disk 88 and ,gear 85 to cou- 'ple these .members together. The eccentric 92 will be thrown over, and removed to allow the lever 87 to be rocked by the cam 90.

thehandles 42 will be operated to rock the levers 52; after which the bolt will be reentered in the lower aperture 55. This operation of the levers 52 is to move the shaft 21 and its associated parts downwardly. The result of this is to move the tapes 23 out of the sheet'receiving position. As'the shaft 59 follows down part waywith the shaft 21 it comes to rest on its bearing 60, in such a position as to leave the gears 70, 71 disengaged and to place the upper runs of the from the cutter rollers. The lowering of the shaft 59 also throws the gear 70 into mesh with the gear 67;` so that thevpulley 61 will be operatedv from the impression cylinder and in a direction reverse to its previous operation. These various alterationsvneed not be made in the exact order here mentioned. The sheets will now -be received from the cutter rollers upon the upper runs of the tapes 62. Justl previous to the reception of the sheet upon the tapes the fly fingers are lowered by the rocking of the shaft 76; so that the ngers lie between 62 as shown in dotted linesin Fig. 4. As the sheet comes upon and is carried along by thetap'es 62 it advances over the'fly ngers, traveling toward a point above the shaft 7 6. When the sheet is entirely over the fly fingers the latter rock to the left, carrying the sheet therewith; and they deposit it printed side down upon the delivery board. During this operation only the fly device is active,- as the printed side up devices, in-

respect the operation of the mechanism for either kind of delivery is just as simple as if the devices were separately employed.

.Owing to the offset position of the fly mount the latter in a fixed position above the carriage and to carry over and deliver the sheets with the ily without interfering with other parts of the mechanism. Furthermore, `the offset arrangement makes it possible no t only to receive the sheetson the fly fingers in a simple manner, but the fingersy lie par'- allel with'the delivery board as they` de'liver the sheets, as ,isL shown in dotted linesin Fig. 3. v

different deliveries are not unnecessarily machine. l y Having described myv invention, whatl I claimis' c5 the socket 81 and will be placedinto l' the A 1.v`: In a printing the 'combination The bolt 54 will be removed, and either of1 complicated by their combination in a single tapes 62 `into position to receive the sheets and slightly below the `upper runs of tapes cludi'ng the carriage, remain idle.
