My invention relates to certain 'improve-r ments in delivery mechanisms which are used in connection with printing or like machines for'taking the sheets or stock in succession i from the, press or machine and then transferring or delivering same to a .pile-receiving table automatically lowerable to accommodate for the growth of thepile of sheets. The objects of my invention are, among other things, to provide an improved delivery mechanism of this type whereby the successive sheets are. first taken from a cylinder of the press or other machine', and are thereafter carried smoothly therefrom and 'ultil5 mately deposited on the p ile so that the chance of injuring such sheets as received on 'such pile is reduced to a minimum.

A further object of my invention is to embody in the delivery animproved tilting tape carrier in conjunction with means for holding the sheets on the tapes during their forward and downwardly-inclined travel on the carrier with the front edge of the sheet hav.- ing a bend toward the pile so that such sheet is gently placed in'position with an oblique movement allowing the air beneath same to flow backwardly as the sheet is deposited on the pile. By my improved construction the sheets are handled easily and naturally and 80 all danger of offset from the printing is avoided. l

With these and other objects in view, the invention comprises the structure and operating parts forming the delivey'mechanism hereinafter set forth as one embodiment of my invention which is then particularly pointed out in the appended claims.

The accompanying-drawings showthis emf bodiment in connectlon with ,a cylinder printing-press, but the invention is not restricted to any particular form or type of printingpress, and my improvements may also be embodied in a sheet-feeder construction.

' Referring to Figs. 1 and 2, the side-frames 11 and 12 support the bearings of the presscylinder 13 mounted on the shaft 14, suchv cylinder 13 Vreceiving the sheets S (Fig. 3 from the sloping feed-board 15 (Fig. 1). T e cylinder 13 is rotated in a clockwise direction parts Iby the gear 16 keyed., to the shaft 14, which The cylinder 13 delivers the printed sheets S on the horizontal delivery-tapes 23 (three being indicated in Fig. 2) which pass around the drive pulleys 24 on the cross-shaft 25 and also around the idler pulleys 26 mounted on the shaft 27 journalled in the delivery frame 28.I The shaft 25 carries drive gears 29 which engage the gears 30 keyed to crossshaft 31 journalled in the side-frames 11 and 12 (Figs. 1 and 2), and the shaftl31 also car- -ries the gear 32 which is driven from gear 16a on the cylinder shaft 14. By such mechanism the tapes 23 are driven from left to right in around the drive pulleys 34 on the cross-shaft Fig. 1) which are driven from the gears 29 keyed to the shaft 25 adjacent the side-frames 11 and 12 (Fig. 2). The rider tapes 33 moving to the right in mutual parallelism with the delivery tapes 23 so as to keep the sheets S confined between them to advance 4such sheets to the-tilting carriage o'r carrier which delivers the sheets in a superposed pile.

The ta-pe carrier comprises the slide mem- .bers 40 and 41 connected by the cross-shaft 42, the members 40 and 41 sliding backward and forward on the

ways

43 and 44 respectively mounted on the side-frames 11 and 12. A joint reciprocating movement is imparted to the slide members 40 and 41 forming the tape carrier for the sheets by the links 45 con- 'necting the members 40 and 41 with the rock arms 46 pinned to the rock-shaft 47 journalled in the side-frames 11 and 12.

The shaft 47 is actuated by the lever 48A pinned to the shaft 47, the lever 48 being connected by the pitman 49 to the crank-arm 50 on the shaft 51 to which is keyed the drive gear 52.v The gear 52 is rotated by aY train of intermediate gears 53, 54 and 55, the gear 55 meshing with the drive gear 18 on the power shaft 19 (Fig. 1).

Inside the side-frames l1 and 12, the shaft` 42 has keyed thereto a pair of bracketsl 56 in which is journalled thecrossshaft 57 upon which are mounted the rear pulleys 58 for the perforated carrier tapes 59 (four being shown in Fig. 2) which are arranged between and outside the delivery tapes 23 and rider tapes 33 and slightly above the plane of the delivery tapes 23 as shown in Figs. 2 and 3. Extending forwardly from the ends of the shaft 57 are the arms 60 which carry the bearings 61 for the-shaft 62 on which are mounted the forward pulleys 63 around which the carrier ajpes 59 travel in a looped path (Figs. 3 and Between the

shafts

57 and 62. is the hollow tubular shaft 64 having the ports 65 which register with the openings 66 in the four open'- faced suction boxes 67 housed about the shaft 64 (Fig. 5), which boxes 67 coact with the under surfaces of the perforated carrier tapes 59 along their upper run as shown in Figs. 3 and 5. The ends of the shaft 64 are mounted in the arm ends 68 (one being shown in Fig. 3) which are journalled on the shaft` 57. The spring 69 coiled about the shafts 57 and 6'4 (Figs. 2 and 5) holds the

cams

74 and 78 pressed against the bars 76 and-82 with a yielding spring engagement. One end of the tubular shaft 64 is connected by the hose 70 with any suitable source of exhaust air-pressure (not shown). Mounted on the shaft 57 and extending rearwardly are a pair of flysticks '71 which are arranged between Yand below the delivery tapes 23 `igs. 1 and 2) As the delivery tape carrier is moved forwardly, it is tilted and moved downwardly the roller 74 (Figs. lfand 3) which rides along the cam-surface 75 formed in the bar .76

mounted on the brackets 77 secured to. the side-frame 12 (Fig. 2). The carrier with the sheet S held on the tapes 59`is advanced from the full line to the dotted line position shown in Fig. 3, during which movement the tapes 59v do not travel beneath the sheet S which is held close to the tapes by the suction boxes 67 and is then delivered to the pile 72 as the carrie` is) retracted (toward the left in Figs. 1 an 3 v- The tapes 59 are caused to revolve .to deliver the sheet S as the-carrier begins to move rearwardly by the rotation of the and (pawl 8O heldin engagement with the ratchet 79 by the springl 8l (Fig. 3). The

gear 78 is operated by the horizontal rackv ytravell of the sheets from the delivery tapes 23 to the tapes 59 is up a slight incline so vthat the sheets will have a close Contact with the tapes 59 as the suction boxes 67 draw the sheets onto the tapes 59.

Referring to Figs. 7 -10 showing a modified i form of tilting tape carrier for depositing the Sheets in which an air blast is used to hold the successive sheets on the carrier tapes `in congearl 78 connectedto the shaft 62 by the ratchet 79- junction with fingers that tilt and lift with the tapes, the sliding members 40 and 41 carry depending brackets 84 (only -one being shown in Figs. 7 and 8) in which is mounted the cross-shaft 8,5.

Secured to the shaft 85 are the arms 86 only one being shown) in which the* crossshaft 87 is journalled, theshaft 87 carrying the rear pulleys 88 around which pass the carrier tapes 89. The tapes 89 also pass around the drive pulleys 90 jornalled on the cross-shaft 91 which is mounted on the carrier frame 92. Midway on the frame 92 is thev cross shaft 93 on which are mounted the tilting fingers 94 which project forwardly substantially in the plane of the upper run of the carrier tapes .89 as shown in Fig. 7. The carrier frame 92 has the upwardly-extending arms 95 in which is journalled the hollow tubular shaft 96 connectedk by the hose 97 with any suitable source of compressed air (not shown). The shaft 96 has suitably spacedapart air ports 98 which register with the depending air-nozzles 99 carried by the shaft 96 (Figs. 8 and 9). Also mounted on the shaft 96 are spaced apart sheet stopsl100 having their forward ends adapted to coact with the lingers 94 to register the leading edge of the sheet S on the carrier tapes 89 as shown.,

' sheet carrier tiltable downwardly to deposit the sheet on a pile,'and pneumatic meansfor in Figs. 7 and 8. Y f

Aiixed on the outer end of the shaft 96adjacent thehose 97 (Figs. 7 and-8) is the latchplate 101 which'is adapted to engage thepawl 102 mounted on the rack 82 at the forward end of the machine asindicated in Figs. 7 and 8, such rack 82`also carryin the yielding pawl pivot-block 103 which, w en the pawl 102 is'engaged by the nose 104 of the latchplate 101, rocks the latch-plate 101 anti- 'clockwise on the rearward stroke of the carrier. The rack 82 also carries the bracket 105 on which is mounted the cross-pin 106 which engages the latch plate 101 to push the lingers 94 and stops 100 back into their coacting sheet-registering position with respect to the carrier tapes 89 on the reverse stroke of the tilting carrier as shown in Fig. 7.

The sheet S is advanced onto the carrier tapes 89 from the'deliverytapes 23 and is registered in properposition between the lingers 94 and sheet stops 100. The carrier is then moved to the right in Fig. 7 and tilted downwardly as indicated by dotted lines by the mechanism hereinbefore described in the construction shown l,in Figs. 1-6. Upon the return travel of the carrier the latch plate 101 is engaged by the pawl 102 so as to raise Athe sheet stops 100 away from the lingers 94 which allows a clear space for the sheet S to be advanced olf the carrier k,onto the pile 7 2- as shown. The tapes 89 are caused to revolve to deliver such sheet to the pile as the carrier starts to move rearwardly by the gear 107 meshing with the rack 82 and connected to the shaft 91 by the ratchet 108 and'pawl 109 heldin engagement with the ratchet by the spring 110. The air'v blast from the air nozzles 99 (Fig. 9) maintains the sheet S on the/carrier tapes 89 in Hatl positi on and then aids in gently delivering same on the pile 72 as the carrier tapes 89 are actuated forwardly (Fig. 7). j f

In both forms of the tilting tape carrier which advances the sheets -from the delivery ltapes 23 and deposits' same on the pile 72, I

have utilized pneumatic means for holding the sheet flat upon the carrier tapes 59 or 89, since the suction through the tapes 59 performs the same function as the air blast from the nozzles 99 in holding the sheets against the carrier tapes during the forward movement of the carrier and while the tapes are advanced to deposit the sheets on the pile.

rIhe detailed structure herein shown and described may be varied in construction without departing from the scope of my invention or sacrificing the advantages obtainable froin its use.
