SHEET-DELIVERY MECHANISM.

Specification of Letters Patent.

Patented Oct. 8, 1912.

To (11/ 'I(/l-U'I7l it may concern B it 'known that I, llnxnr'A/Wrsn \Vooo, a citizen of the United States, residing at Ne York, in the county of New York and State of New York, have invented a new and useful Sheet-Delivery Mechanism, of which the following is a specification.

The object of this invention is to provide a new and improved nechanism t'or delivering sheets, particularly adapted for use in connection with printing machines.

The particular object of the invention is to provide a new and improved way whereby a reciprocating carriage or carrier can act to turn over and deliver the sh s-t. so that. if the mechanism is used in front of the inn presslon cylinder of an ordinary printing machine, the traveling carriage will deliver the sheets with their last printed-side down. This new operation is accomplished by providing a gripping or seizing means independent of the carriage or carrier which engages and holds the edge of the sheet in trout oi the carriage as the same moves lorward with the sheet thereon. which gripping or seizing means after it seizes the sheetmovcs out of the way down below the carriage, so that as the carriage moves forward the sheet will be turned over around the front end of the carriage and delivered under the carriage.

The carriage is preferably made in the form of a of tapes, and during this delivery action the set of tapes is caused to run at such speed as to advance the sheet at the proper speed for this turn-over delivery, so that there will be no slip between the sheet and the tapes. This mechanism thus accomplishes the function of the usual ily delivery. This mechanism may be also advantageously employed in a so-called convertible delivery by adapting the reciprocating,carriage to work in any of the ordinary ways to deliver the sheets printed-side up, and by providing means whereby said gripping or seizing mechanism Way be thrown out of operation while the sheets are delivered printed-side up.

I have shown the carriage arranged to deliver the sheets printed-side up by simply causing the carriage-tapes to interinesh with the usual set of delivery tapes which run the sheet down from the impression cylinder on the plan described in my Patent No.

construction, and need not be described at 516,386, dated March 13, 1894, although, in some cases, I. intend to use litters or carriage fly-sticks in accomplishing the printed side up delivery, as shown in my Patent No. 594,055, dated Nov. 23, 1897. The simplest arrangement, that is using merely the two sets of inter-meshed tapes, is shown in this vase for the purpose of illustration.

The invention can best be understood in detail by referring to the accompanying seven sheets of drawings, in which,

Figure 1 is a side elevation of enough of the mechanism to illustrate my invention. Fig. 2 is an elevation of the cam which is used to operate the gripping nechanism. Fig. 3 is a plan view of the reciprocating carriage. Fig. =1 is a side elevation of the same. Fig. 5 is a detail of one of the ratchet mechanisms used to actuate the carriage tapes. Fig. 6 is an end elevation of the gripping or seizing mechanism. Fig. 6 is a detail of the means for guiding thesheet into the gripping or seizing mechanism. Figs. 7 8, 9 and 10 are diagrammatic views illustrating the operation of the seizing or gripping mechanism. Figs. 11 to 14 inclusive are diagrammatic views showin the operation when the sheet is delivere printed-side up, and Figs. 15 to 18 inclusive are diagrams showing the operation when the sheet is delivered pr nted-side down.

Referring to the drawings and in detail, A designates the impression cylinder of an ordinary form of printinganachine.

B designates the usual set of delivery tapes which are trained around tape-rollers (J and D, the tape-roller C being driven con tinuously in the usual way by gearing from the impression cylinder, .as indicated by dotted lines in Fig. 1, so that the top surface of said tapes will run away from the impression cylinder. The sheets are direct;- ed out onto these continuously running delivery-tapes B by means of the usual stripper fingers S. These parts are of ordinary greater length.

Brackets E-E are secured to the sidet'tames of the machine, and the delivery table F is held by said brackets and by standards G. i a

Extending up from the brackets E-E are supplemental brackets 10. Secured bet-ween the supplemental brackets 10 and the frame- "1;; from the supports for the u miles, are guides Ill--11.

t n Y i r. an is ml e on on m e some sin is. ii which is as the gem of toe inoelni shown 111 Fig. l. A rack 13 V5 raged between the irmne pro ecting; from ollier impression cylinder suppers 21ml between the corresponding supplemental bracket ll so that its teeth progeci npwerflly or ogsposrlely relallvely to the reoloi-eeih l2. Us the sirles of the deiivez'y table l formecl son ble guides 1 ,2 1 1 w .e w iii-lo oesignmo the sme-irsmes or the reoipromting or delivery sesrrisge; These sidofreines have rollers Tl*3--'ll which run on top of the guides fll--11{ end.- rollers 3/2 47 which run on the guides Ll-Ql on the delivery wlole. By this construction the carriage is capable oi rsciproossion sway from sncl toward llie impression cylinder and over the delivery-table. Joiirneleil in the front; emi of the osrrisge ironies 15-15 is a lope roller 18. Journaleol in the rear end of the carriage-frames 15-45 is s slmfi 19 carrying a numli er of tape rollers 20., Suitable delivery-tapes 21 are iminefl be tween the tape-rollers 2G and like roller 18.

The carriage or delivery ispes inierinesh with the delivery tapes as describe& in m Patent No. 516,886 previously rnentione and as shown in Fig. 3.

Rigitlly seourecl on the shaft 19 are rsbcliet wheels 2Q-Q2L Looselv arranged on the shsi't 19 and meshing with the upper rack 12 is s. gear 23, onol also loosely errangerl on said. shaft 19 is a gear 24: meshing will; the lower rack 13.

The gears-23 and 24 are provnioel with powls 25 to operate the rstclieowl eels. The disposition of those years, rstolieowheels, and pawls is exactly the some on each side of the carriage, except shotit will be noted that; the gear meshes with the up or rock.

and that the gee-r 2s meshesjwiili i e lower rack, whereby as the carriage isreciprooated, the oscillation of the gears 23 and 24 Will be opposite relatively co each other.

The pewle 25 are provided with springs 26 to keep the same in operative position, and witlrpivoted throw-out pieces 27. B3 moving a throw-out piece so that its end is pulled outwardly from the center, and by inserting a pin in the end of the some, sn in a hole bored in the gear for this purpose, the pawl controlled by the throw-out maybe thrown out of opgeretion.

As heroine.flier described when the sheets are delivered prinleclside up, the gear 23 and its retoheb mechanism is used, and the gear '24 and lie ratchet mechanism thrown out of'operetion; and when the sheets are delivered pI'lIItQd-rSldQ clo n, the gee-1 24c and its ratchet mechanism is used, anal the gear 23 and its ratchet; mechanism thrown out of operation.

- noiosso 2S designates the Cain-shaft of file mar chine, which is gosreii in the usual manner to make one turn for each cycle of operation.- Fitted on ihe end of this min-sheik is orank-clisli 29 Wliidi carries :1 crank-pin 330 which connects lo'y piiman ill to the end of a. lever 32 secured on lhe onrl of :1 shaft. 33 jonrnsled in the braoliel's E. Secured on said shaft 33 are arms 34 which connect by links or pitmen 35 to the carriage frames 15-15, whereby the carriage is reeiprooated to deliver the sheets. i

The mechanism thus far desoribel, with the exception'of. the gear 24: and its ralehet mechanism, constitutes a simple delivery mechanism for delivering the shoots primedside up on the delivery table.

The operation of this apparatus is shown in the sixth sheet of drawings.

The sheet firstpesses down onto the do livery tapes B, shown in Fig. 11. which are continuously running.

The carriage then moves away from Hie impression cylinder, as shown in Fig. '12, the carriagelsgoes remaining stationery as the gear 23 turns in n drrectlon to ratchet the pawl of llllfi gear 23 around its ratchotwlwel 22.

This movement will carry the sheet out over ills delivery ieble, as shown in Fig 13.

. Now as the osrris e makes its backward or reiiirn stroke, as s own in Fig. M, the carrings tapes 21 Wlll be pulled from under the sheetby reason of the gear 23 turning in a direction to cause its pawl to engage its ratchet wheel and turn the shaft 19. By

this operation the carriage tapes will peel from under the sheet, which will settle down on the clelivery table and be delivered printecl-siile up.

As thus far described, the mechanism is substantially the same as described in my f latent No. 516,386, and constitutes a meohsnism for delivering sheets printeclside up. The mechanism whereby the sheets may be delivered prmtedsicle down will now be (lesori'lieel.

Journaled in the brsckets E is a shafli 36 :Wl'llCll carries a gripper or seizing mechanism. 'lhis shaft is oscillated by means of l a cam 37 seem-ed on the cam-shaft 28. The

outline of this cam is shown in detail in Fig. 2, ond tho fnnotions'of. its various surface will hereinal ter be described. A. lever as is pivoted on the side-frame and carries s roll 39 which engages said, cam 87. This pivoted lever connects 'by link 40 to an arm 4C1 mounted on the end of seicl shaft 36.- A. spring 42 is arranged on said link 40 between a block 43 secured '00 the side-frame, and a. collar 4 imljustably secured on the link 40, whereby the spring is put under tension, and the roll 39 normally kept in en gsgemen'c with the cam. The lever 38 is roviderl with a hole 45 which regisiers with a hole-s6 in the rear side-frame, whereby er F by pulling said lever away from the cam and by inserting a pin in said holes -15 and $6, the said lever can be thrown out of operation. The lever is thrown out of operatien when the sheets are delivered printed-side up, as previously described. Journaled in the supplemental brackets to is a sha ft 47, mounted on which are a number of sl'ieet-stoppers or directors 45 which are made out of light spring steel. The shaft 1-7 is oscillated by an arm 49 secured to the end thereof, which is connected by link 5a) to a short arm 51 projecting from the hub of the arm 41. The function of these directors to pat or direct the sheeet down into the gripping mechanism as it seizes the sheet, as shown in Fig. 7, to prevent the end of the sheet from riding over the gripper mechanism. After these directors guide the sheet into the gripping mechanism, they move up out of the way, as shown in Fig. 8. In some cases spring guiding strips net) are arranged as shown in Fig. 6" to guide the edge of the sheet from the tapes B into the gripping mechanism.

The gripper mechanism will now be described.

Secured to the shaft 36 just inside of the brackets E*-E are arms 52, journalcd in the ends of which is a shaft 53 having a keyway. The shaft 36 also has a key-way cut therein as shown in Fig. (3. Secured inside the. front bracket E is a segment 54-, and secured on the shaft 53 is a cot'iperating segmeat .35. which segments are shaped so that as the shaft 5 is oscillated around the shaft 36, the shaft 53 will be turned on its own axis. The gripping mechanism is mounted on these two shafts 3t; and 5 and is made up of a plurality of individual grippers. As many of these grippers are used as the size of the press demands. 'lhesc grippers are adjusted axially on the shafts 3t and 53. and held in place thereon by setscrews, whereby they may be set in any desired posithn, depending upon the charactcr of the sheets which are to he dclivcrtal. These grippers are the same in ti'illrll'lll ion. and one will now he described. The gr pper in tho first place is made up el' a double l'ramc fitt- 543 which comprises two huhs keyed to the shaft 5 aml depending ar'us 57 m. The hubs are conncctcd toget law by a tongue 58 which tor-n3); the lower gripperjaw. and which is provided with a stop 59. Arranged l'ietwccn the hubs of the grippcr so as to lit loosely on the shaft 6., is the upper jaw (30 of the gripper. it will he sccu by this construction that the upper jaw (it) can turn on the shalt 513 relatively to the lower jaw 58. so as to open and close on the sheet. The upper jaw is provided uilh a projecting segment til. The upper-jaw is kept normally closcd by means of a spring (if arranged on a rod ill which is attached to a small huh projecting from the rear of the upper gripper. and which passes through a block mounted on the trigger hereinafter described. A segment (ll meshing with the segment (31. is pivoted on a pin 5 secured hetwecn the gripper frames. This segment has a projecting arm lit A trigger (37 is pivoted on a pin (35 also secured between the frames of the gripper. This trigger has a head or catch tit) which is adapted to engage the projecting end T0 of the movable upper jaw (30 of the gripper, as shown more particularly in Fig. 10. This trigger is provided with a depending arm T1 by which it may be l'tltilrsfll. A cam-block T2 is mounted on the shaft St; for each gripper. Zach camblock can be adjusted on the shaft 3b to match the adjusted position of its gripper, and held in its adjusted position by a set screw. Each cam-block has a projecting cam 73 to engage and operate the arm tilt of the segment. and a pin 74 to engage the arm 71 of the trigger which holds the mnvable jaw of the gripper open to release the same. This mechanism is operated entirely by the oscillation of the shaft it; through the cam 37.

The operation of the gripping or seizing mechanism in combination with the 'arriagc'. will now he described.

Suppose the gripping mechanism to have just closed on the end of the sheet. as shown in Fig. 7. The gripping mechanism is shown slightly raised above the front carriage roll 18. which is about the position at which the gripping mechanism takes the sheet as the delivery tapes are a little above the carriage-tapcs. The operative surface of the cam 3T is divided into four sections a -b- -('r/. in Fig. 2 for convenience of dcscriplion. 'hen the gripper mechanism taltcs the shcct as shown in Fig. T, the roll rugaging the cam 37 is in the position hc twccn lhc sections u ol' the 'am. and the g'rippcrs' are at their positions neare t the impression cylinder. Now as the cam turns to bring" the ection (1 thcrcol into operation, .hc shal't Ill; will be oscillated from the. posi' tion ;-hown in Fig. T to the position shown in Fig. 8. This will cause the grippers to revolve around the shaft Ill so as to swing to a position below the carriage tapes, and will cause the shaft 53 to revolve to turn the grippcrjmvs, so that they will point toward the delivery table, as shown in Fig. 8. As this movement of the grippers takes place, the carriage starts on its delivery movement to and the delivery table, but the grippcrs move in advance thereof so that the roller [H of the carriage does not engage or touch the gripper mechanism in any way. The grippers are turned toward the delivery table. so that no fold or crease will get in the sheet, ow as the carriage moves out over the delivery table the grippers will stand stationary; in i'hc PUFFiiIlOil shown Fig. 8, by rmson of the circular SCiiIiOii b oi l'hc min.

As prvinously ilesm'ihed, when the sheets are in he deliverml prinimhsiilo down. the gm: 233 and its i'aiclichmechsnit' n rhi'own out of ()I'iPlRl'iOll. anal llic gun mid ifs By reason ol this kHllUSlHlilil'. as; the carvings nun-vs forward over tho doliwry inhlc, flic lop of tho (lclivei'y tapes will run forward in the arriago at practicum the smell of the forward movement thercof. so that the sheet will he moved fOZ'WfUTl in the carriage. and so that theme will he no firiclion hclween the slicet 21ml dclivcij" mp0s. ihis move mcnt hikes plow, the sheet will bc inr'nml m or, as indicated in the diagrammatic Figs. 15 and 16. and when the carriage roachus practically the end of its forward niovonwnt, the sheet will be complcfely turncd over, so that when 'oleased it can settle down on the delivery table printed-side clown. as shown in Fig. 17. Just before the carriagereaches its extreme forward movement, the section 6 of the cam 37 comes into ope-ral'ion. The section 0 is slightly elevated malotivciy to s'cction 5 of the cam. This slight difference will cause the shaft to have a slight additional oscillation, that is, from the posiiion shown in Fig. 8 to position shown in Fig. 5 The parts are so arranged that by reason of this additional oscillation, the arm 66 pr0- jecting from the segment (34 will engage phc cam 73 and oscillajn'ie tho ssgn'icnis. opening; the movable gripper-jaws which will. he held opon by the engogon'ionf of tho Wiggins previously describe-1i. This will rclczisc the sheets from the grippers, and will allow the some toloe delivered printed-sida don ii on the delivery table. Now as the our logo makes its return stroke toward iihe impression cylinder, the section (1 of the (rain will hold the gripping mechanism in the position shown in Fig. 8. As the carriage nearly completes its inovcment toward i119 imprcs sion cylinder, the section 7) of the man will comeinto operation. This Will swing the*p "rippers to the position shown in Fig. 9. hack to the carriage, as shown in Fig. 10, the grippers still being open, and engaging the sheet which is at this time just in posit-ion to pass into the grippers. Just as this takes place, the pin 7 1. on each cam-block will engage the pi'qcctiing end of the trigger which cooperates therewith, and by reason of the can tinned upward movement of the arm 4'1 will disengage the triggers and. allow the movable aws of the grippers to size (he sheet, thus bringing the parts hack to the posit-ion shown in Fig. 7 when the cycle of operation of tapes monniecl the! i will be completed.
