l b all whom item?) concern a lite itlmownthat i Henna A. Wis Woes, citizen of the United States, and a resident of Flew York, in the county of New York and State of Flew York, have invented cernew and useful Sheet-Manipulating hfechanism of which the following is a specificatipn. C

The ohyect of this invention is provide new improved manipulating mecharegister. ll/leans are also provided whereby the grippers are lifted and held away from the face of the laten as they are moved orer the same and whereby the grippers are allowed to move back toward the platen when the impression is made.

The invention further consists of certain combinations hereinafter-described and churned, which will be understood from a detail description of the mechanism.

'Fhe invention is illustrated in the ac companying six sheets of drawings.

the chains which carry the grippers. Fig. it is a side elevation of a modification herenafter described.

Referring to the first five sheets of drawlngs. the mechanism therein illustrated will be described. The mechanism is mounted in side frames l0-l0 which may be tied together, if desired. dournaled in these side frames is a driving shaft if on which may be arranged the usual tight and loose pulleys 12 and 13 for imparting power to the machine. Finions l-llld are secured on the driving shaft it and mesh with large gears lei-l5 arranged on the operating shaft 16 of the machine. A. shaft 17 is fitted in the frames l0lt) and pivoted on the same are powerful levers or frames 18l8 which carry the usual chase and furniture so that a form or forms can be locked in proper position to cooperate with the platen F. 'ilhe platen F is hung on shaft 27 and strikes against bracket 270 as shown in Fig. 4. This construction also afiords a convenient means whereby the platen may be turned flat or into horizontal position for makin ready. An inking mechanism ll, of any 0' the usual types is arranged between the levers or frames 18- 18. This inking mechanism is arranged as is couunien in platen printing presses so that the form inking rollers will travel down over and ink the form or forms when they are retracted or moved away from the platen F. I The large gears do carry wrist-pins 19-19 which are. connected by links or pitmen 20-20 to shaft 21 on the frames 1818. The shaft 21 is made eccentric in the manner common in platen printing presses so as to constitute a throw-ed mechanism; that is, so that when the shaft is in one position as the frame is moved up toward the platen, it willnot contact therewith and so that when the shaft is in the other position when the frame is moved up, it will contact with the platen and print the sheet.

As shown in the drawings, the shaft 21 is in the printing position, it being understood of course, that when the form is to he tripped, the shaft is moved to its other position by means of mechanism commonly employed in platen printing presses.

The sheet manipulating mechanism consists of two chains (,C made up in principal part of the usual links. These chains are.

trained over sprockets 2222 mounted on a shaft 23 journaled in the frame, over sprockets Q L-Zl mounted on a shaft journaled in the frames, over sprockets 26-26 secured on a shaft 27 journaled in the frames, and over sprockets 28-23 secured on a shaft 29 journaled in the frames. Shafts and 29 can be studs with loose sprockets if desired. The chains carry a series of gripper mechanisms. there being as many gripper mechanisms as the chains are sheet lengths in extent. For example, in the drawings shown, the chains are made of a length corresponding to seven sheet lengths plus the necessary clearance between each set of gripper mechanism and seven sets of gripper mechanisms are arranged between the chains. The sheets are fed to the gripper mechanisms down a suitable feed-board or guides 30. An automatic feeder may be arranged in connection with the machine or the sheets may be fed by hand. The details of the feeding mechanism form no part of the present invention and therefore are not illustrated or described at length. The sheets may be fed from the position indicated at S for an underneath feed or from the position indicated at S for a top feed.

Two delivery tables D and D are arranged between the frames at the positions indicated on relatively opposite sides of the chains. upper delivery table 1) they will be delivered printed side up. If they are delivered on the lower delivery table D, they will be delivered printed side down. The sheets can be delivered on either table, as desired, by the mechanism hereinafter described and this constitutes an important point in connection with the invention.

Each delivery table is provided with a set of the usual stop fingers 31 to position the sheets as they are delivered. The chains are given an intermittent movement in the same direction. equal to thedistance betweeneach set of gripper mechanism, by the following means: A cam is arranged on the operating shaft 16 and engaging the same is a roller 33 secured on an arm 3-1 which latter is connected by a link 35 to a rack 36 which is fitted to slide vertically in suitable guides. a spring 37 being employed to keep the roller 33 in engagement with the cam 32. The rack 36 engages a pinion 38 loosely mounted on the shaft '25. This pinion car ries a spring-pressed pawl 39 which cooperates with a ratchet-wheel 40 tightly secured on the shaft 25. By this arrangement, as the rack 36 moves down, the pawl 39 will run over the ratchet-wheel 40 but on the upward movement of the rack 36. the pawl will operate the ratchet-wheel and turn the shaft 25. By this arrangement, the chains will be intermittently advanced. a

The mechanism is timed and arranged to If the sheets are delivered on the,

operate when the frame is retracted from the platen and sons to give a movement to the chains equal to the distance between the sets of gripper mechanisms.

The gripper mechanisms are the same in construction and one will now he described in detail and reference to follow such dc scription should be had in Figs. 5 to 10, inclusive. A pair of the inner links of the chain directly opposite each other is constructed, so as to have a boss 41 and extending arm 42 in which is secured a pin 4-3 and a projection l4, it being understood of course. that these parts come on the inner side of each of the links. (See Figs. 9 and 10.) Driven into the bosses 41 are studs 15 and pivoted on these studs are gripper carrying bars 46. shown in Figs. 7 and 8, the gripper carrying bars being kept in place on the studs 45 by collars and screws. The gripper bars have projections or stops 17 which are arranged to strike against the projections 4- on the links to determine the normal position of the gripper mechanism. These projections are kept in contact with the gripper bars in their normal positions by means of springs 48 arranged between the pins 43 of the inner links of the chain and pins 49 driven into the sides of the gripper bars, the springs 48 being housed in suitable sockets pivoted on the pins 4.3 and 49. By this arrangement, the gripper mechanism hereinafter described, can be lifted or turned about the studs 45 as pivots but it is kept in normal position by said springs 48. Secured between the gripper bars 46 is a gripper jaw 50 made up of a piece of flat metal. A shaft 51 is journaled in bearings formed in the ends of the gripper bars 46-46-and a series of gripper fingers 52 are secured on the shaft 51. Stops 53 are secured to the gripper jaw 50 so that when the sheet is fed to the gripper mechanism it may be properly positioned. These are preferably adjustable. Secured on the shaft 51 just inside its bearing in the gripper bars, is a lever 13% which carries a roller 55. The gripper fingers are kept normally in contact with the gripper jaw by means of a spring 56. The lever 54 projects upwardly, as well as downwardly and the spring 56 is arranged between a pin 57 secured in the upward part of the lever 5t and a pin 58 secured, in the gripper bar 46. A pin or stud 59 is driven into a post extending down from each gripper bar 46 and a roller 60 is journaled on each pin for a purpose hereinafter noted.

- To lift the gripper fingers so that the sheet may be seized for manipulation, the following mechanism is provided: A cam lever 61 (Fig. 4) is pivoted on the inside of one of the frames. This cam lever is operated by a link 62 connected with a doublepronged lever 63, which lever carries a roller inaaaaa tit hearing on a cam 65 secured on the operating shaft 16 ot the machine. The cam 65 is proportioned and arranged so that when the chains come to rest the gripping fingers will be raised as shown in Fig. 4t, so that the sheet can he ted in on to the gripper jaw in registration with the stops 53 and so that when the sheet has been ted into this position, the gripper fingers will close down on to the gripper jaw and seize the sheet tor manipulation, all while the chains are stationar so that at the neat movement of the Ell chains, it will he carried "forward down over the platen P. lBy opening the gripper tingers only just before the sheet is to be led, the necessity tor providing special means for lreeping them open during the travel ot the carrier is avoided. This secures an eitcellent register. lit is desirable to move the gripper mechanisms over the lace oi the platen P without contact therewith but to allow the gripper mechanisms to come down into the same plane as the lace of the platen when the impression is to be made. This is the purpose ot pivoting the gripper mechanisms on the chains as before described and the tollowing mechanism is arranged to turn the gripper mechanism in the chains as it passes over the face of the platen: Secured on a shaft 660 so as to stand at each side oil the platen P are blade cams 66, one at which has an extending lever 67 provided with a roller 68 hearing on a cam 69 secured on the operating shaft 16 ot the machine. The blade earns 66 are set in position to cooperate with the rollers it so that when the gripper mechanism moves over the upper edge ot the blade cam it will be held out train the platen and the cam 69 is so an ranged that the blade cams will be thrown out relatively to the platen as each gripper mechanism moves down across. the platen, whereby the gripper mechanism will be moved clear 0 moves over the same, as shown in Fig. 4", and whereby when the gripper mechanism is moved down over the platen, the same can drop to'proper position to come substantially in line with or in the same plane as the lace at the platen whereby the impression can be made on the sheet without any pinchin, or creasing ot the paper.

lt is also extremely desirable to register the chains as the rinting is done. For this purpose pins 70, shown in Fi g. 6, which connect the links of the chain at the points where the gripper mechanisms are carried, are extended to form registering pins. lFitted to slide in suitable soclrets are bars 71 which have socketing or tapering mouths 710, as shown in Fig. 1. Each of these bars carries a pin 72 which fits in apivoted lever 73. Dne of these pivoted levers carries a roller 7t which works on a cam 75 secured on the shaft 16 of the machine. This cam is the face of the platen as itso arranged that when the chain comes to rest, the bars 71 will move up and the notched or tapering months 710 of the same will engage the registerin 9 pins 70 and thus register the gripping mec ianism that is below the platen so that the impression will be made in the proper position on the sheet and so that any irregularities or slaclr in the chains will be compensated tor.

Atter the sheets have been printed, they will he carried by the movement ot the chains before described out over the delivery tables D and D. H it is desired to deliver the sheets on the table D with their printed.

sides down, cam 76 is secured to the side frame in position to coiiperat/e with the roller 55 so that as the chains come to rest, the grippers which are at the left of the delivery table D will he opened and the sheet allowed to settle down on the delivery table. This delivery can talre place very easily and accurately as the grippers open substantially as the chains come to rest. Dn the other hand it it is desired to deliver the sheets on the delivery table D printed side up, cam 76 is removed trom the position previously described-and set at the right of the delivery table D. The delivery then takes place substantially as previously described except that the sheets are delivered the other side up. Either method of deliverycan he adopted by setting the cam 76 to coiiperate with the proper delivery table. Thus by this mechanism, sheets are taken, carried over the platen, brought in line or in the. same plane as the platen, registered in proper position, printed, carried forward, and delivered either side up as desired. By using this sheet manipulating mechanism in connection with the automatic feeder, a very rapid and accurately working printing mechanism is provided.

in some cases it is not necessary to arrange the machine for delivering the sheets both ways and when it is not desired, the machine can be somewhat simplified, as illustrated in Fig. ll. v

As shown in Fig. it, the mechanism is arranged substantially as before described except that the delivery table D is omitted and the delivery table D alone provided so that the sheets are delivered printed side down. For this arrangement, the sprockets 28-428 and the shaft 29 can be omitted and the machine may be more compact. This arrange ment allows for the convenient use ot a top side feeding mechanism.

ln some instances it may be desirable to move the chains so as to carry the sheets up over the platen and this arrangement, while within the scope ot the broad claims made in this application, is specifically shown, described and claimed in a companion application tor patent tiled January 22, 1906, Serial No. 297,327.
