DELIVERY MECHANISM FOR PRINTING- PRESSES.

Application filed October 2, 1925. Serial No. 60,031,

The present invention relates to a new and improved delivery mechanism for use wlth printing or:cutting and creasing presses or the like, and more particularly to mechanism especially adapted for the'handling of heavy stock.

Heretofore,- with machines of this type handling heavy stock such as pasteboard or the like, d'ifiieulties have been experienced at the delivery end of the machine. The stock rapidly accumulalcs'at the delivery end and is heavy and cumbersome"tohandle and was .not delivered to a position convenient for handling by the operator. The speed of the machine was therefore reduced as it was necessary to stop the machine at relativel short intervals for the removal of stoc worked upon.

Itv is an object of the presentinvention to provide means for the delivery of worked stock whereby the stock can be readily removed without interfering with the operation oi' the,ma'chi ne.

I t' is a further object to provide stock'delivery receiving means from which the stock may be easily removed with the aid of gravity.

It is an additional object to provide a mechanism of this character in which the.

delivered sheetsmay be temporarily retained as desired, upon an'intermediate portion of the mechanism.

Itis also an object to provide a mechanism which is relatively simple in design and adapted for commercial production. and

operation. Other and further objects will appear as the description proceeds. We have illustrated a preferred embodiment of our invention in the accompanying drawings, in which Figure 1 is a side elevation of a portion a press with our invention attached thereto; Figure 2 is a plan View of the delivery mechanism i Figure 3 is a fragmentary view on an en larged scale showing a portion of the mechanism at the inner end of its stroke;

The delivery table 11 is supported at one end upon the crossbar 12 carried by the brackets 13 secured tothe end of the press frame 14. The channel iron 15 rests upon the bar 12 and carries the set screws 16 by means of which thetable may be adjusted and held in adjusted position. The outer end of the table is supported by the rods 17, the lower ends of which are pivotally supported at 18 in the end of the press frame. The upper ends of. the rods 17 are adjustably secured to the lugs 19 carriedin the brackets 20 located on the lower side of the table 11. The table is provided with the adjustable side guides 81..

The outer edge of the table 11 carries the shaft 21 secured thereto by brackets 22.

This shaft 21 has ke ed thereto the 'stop members 23. Y The sha t is normally held in position with the stop members at: right angles'to the table by meansof the coil spring 24. The track members 25 and 25' are supported from the upper ends of the brackets 13 and 13' by the bolts 26 and 26' respectively. The track member 25 carries the cam member 27 to the lower end of which is pivotally secured the cam rocker 28. The upper portion of the member '27 is provided with the cam surface 29. The

'outer end-of the track member 25 carries the cam member 30 pivotally secured thereto at 31.- Themember 30 is provided with a flex- ,ible handle 32, \v hiehn'ormally rests upon The hangers 34 at track members 25 and 25 carry the cross rod 7 35, and the hanger 34 on member 25 also supports the cam rocker 36 whichjisTpivoted about the point 37. The rod 35 carries the stop members 38. The cam rockers 28 and 36 carry the rod 39 pivotally supported between them. This rod carries the stop members/i= and 41 which are adjustably secured to the rod by. set screws.

The reciprocated delivery carriage is best shown in Figures 2 and 5, The side frames 42 and 42 are supported from the blocks 43 and 44 which rest on the tracks and 25. Theside frames have the downwardly depending portions 45 and 46 which extend on the inner sides of the track members and which support the cross frame members 47 and 48 respectively. The slats 49 are supported upon these frame members 47 and 48.

he method of connection of the slats 49 is shown in detail in Figure 8, the spring member 50 engaging. the under side of the cross frame member and yieldinglyholding the slat in place.

The downwardly depending portions 46 of the side frames 42 and 42 have journaled therein theshaft 51. The knurled roller 52 is carried by the shaft 51 and this shaft also .carries the gearwheel 53. The lower end of the ortion 46 of frame 42 is provided with a ug 54 adapted to engage the members 40 and 41 in the operation of the machine. The side frame members 42 are rigidly cross connected by the cross frame member 55. They are also cross connected by the rock shaft 56. To the rock shaft 56 are fixedly secured the stop finger carriers 57 which carry the stop fingers 58. The roller arms 59 are carried upon the shaft' 56in suchmanner as to rotate freely thereon and they carry at their lower ends rollers 60 which normally rest I upon the knurled roller 52. 4

- The outer end of the shaft 56 has keyed thereto the bell crank lever 61 which is provided with the cam rollers 62 and 63 adapted to'cooperate with the cam surfaces 29 and 30. The cross frame member 48 as shown in detail in Figure 9 carries the brake members 64 adjustably held together by .the bolt 65 and wing nut 66. These-brake members en- I gage the end of the knurled roller 52 and prevent overrunning of the roller.

As shown in Figures 5 to 7 the track member 25 has secured to the o posite ends thereof the guide members 6 and 68. These members together with'the track member guide the vertical movement of the rack member .69. This member 69 is provided on its lower surface with the rack 70. i It is urged downwardly by the springs 71 and 72 housed in bores in the guide members. 67 and .68. The rack member69 is held against downward movement by the cam rockers 28 and 36. Y

- The press is provided with mechanism in cluding-b'elts73 and 74 for delivering the sheets to the reciprocating carnage. Thls mosaic mechanism, however, forms no part of the present invention. The bell crank lever 75 is connected by the'rod 78 with the reciproeating carriage It will be understood that this drive properly co-ordinates the movement of the carriage with the delivery of sheets from the ress.

In the operation of the press, the sheets are delivered from between the belts 73 and 74 onto the slats 49 of the reciprocating carriage. The forward edge of the sheet is engaged by hooks 58 and its forward movement limited. This forward edge will be gripped between the knurled roll 52 and the rollers 60. The carriage moves downwardly to the right as seen in Figure 1 underlpower supplied by the rods 78,- This movement is co-ordinated with'the feed of the sheet between the belts-73 and 74.

' i It will be notedthat as the carriage moves downwardly, the rack member 69 is in the position shown in Figure 6 and the-rack 70 does not mesh with the gear '53. The roller reaches the end of its movement, the cam roller 62 1'idcs up on the surface of the cam 30 which rocks the shaft 56, This rocking movement of the shaft 56 ii ts the stop fingers 58 out of engagement ith the'end of the sheet.

Also, at this end of thestroke the lug 54 engages the adjustable stop member 41 which moves the rod 39 longitudinally and rocks the two cam rockers 28 and 36. They are moved to the position in which they are shown in Figure 5. The rack member 69 is forced downwardly by the springs 71 and 72 and the rack meshes with the gear 51.

The carriage now starts-on its reverse movement back toward the press and as 1t so moves the knurled roller 1s rotated-1n the clockwise direction as seen in Figures 1, 3

and 4.- This rotation of the roller feeds the sheet off of the end of the reciprocating car-- Kile resting on the receiving vtable 11. The s cam surface 29 and rocks the shaft 56. This .52 is held against rotation by thebrake .members 64. As the reciprocating carriage brings the stop 7 fingers- 58 down tof their "lower position and into the path of the 'next v sheet to be delivered from the press to the carria e. Also, the lug 54 engages the ad-:

and swings thatrod to the, left as seen in Fi res 1, 3 and 4 and to theright as seen in -igures 5 and 6. This movementswings 1 j'ustabTe stop member 40 carried by rod 39 the cam rockers'and forces the rack member 69 upwardly so that the rack 70 clears the gear 53. Rotation of the roller is promptly it is desired toremove sheets from the table,

the stop members 23 are swung downwardly as indicated in broken lines in Figure 1 and the. pile of sheets may be easily slid by gravity onto the stripping table 80. As soon as the pile has cleared them the stops 23 swing upwardly due to the spring 24.

If it is desired to stop the deposit of sheets on the table 11 during this operation this may be accomplished without stopping the press or the delivery mechanism. In the form of construction shown in Figure 1, the flexible handle 32 is swung outwardly to clear the stop 33 andthen swung downwardly, the cam member 30 rotating about the pivot 31, This brings the cam surface level with the top of the track member 25 and out of the path of the cam roller 62. Consequently, the shaft 56 is not rotated at the end of the stroke and the stop fingers 58 remain in the path of the sheet. The sheet is, therefore, not delivered from the carriage during the return movement of the carriage, but is carried back toward the press. ,The succeeding sheet is delivered on top of this sheet upon the carriage. -When the table 11 is cleared, the cam 30 is raised to its operating position and on the next stroke the several sheets on the carriage are together deposited on the table.

In the form of construction shown in Figure 10, the cam 30 is automatically swung down out of thepath of the cam roller 62 when the stops 23 are swung downwardly to permit the removal of the sheets from the table. This is accomplished by the link 83 which is pivotally connected to the bar 84 secured to the cam 30, and the arm 85 which is fixedly secured to the shaft 21 and pivotally'connected to the lower end of the link 83. When the stops 23 are permitted to swing upwardly, the cam 30 is automatically restored to its operative position and the sheets upon the carriage are delivered to the table upon the next return stroke of the carriage.
