DELIVERY MECHANISM.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application filed May 23, 1904. Serial No. 209,148.

To all whom it may concern:

Be it known that T, WALTER Soor'r, a citizen of the United States of America, and a resident of Plaintield, Union county, New Jersey, have invented certain new and useful Improvements in Delivery Mechanism, of which the following is a specification.

My invention relates generally to delivery mechanisms for sheets of paper or other flexible material, and has more particular reference to sheet delivery mechanism used in printing presses.

In the class of printing machines known as two-revolution, stop cylinder and similar machines, the printed sheets are generally delivered with the printed side up, sometimes, however, it is desirable to deliver the sheets with the printed side down. Furthermore, it is frequently desired to change from one style of delivery to another in the same. machine, when doing different classes of work.

The object of my invention is to produce a structure of the character described, capable of delivering the sheet with the printed side down, and also to provide interchangeable means whereby the sheet can be delivered either with the printed side up or down at will in the same machine.

In a companion application filed on the 17th of February, 1904, Ser. No. 194,025, I showed a structure characterized by a reciprocating sheet turning means, and a gripping mechanism for turning the leading edge of the sheet whose location is fixed with relation to the reciprocating sheet turning means and extraneous of the same. The gripping mechanism was described as being either rotating or oscillating, but was specifically shown as rotating. Tn the present application, I have shown an oscillating gripping mechanism associated with a reciprocating sheet turning means, but located extraneously of the latter.

Other features of construction and combination of parts will appear as the specification proceeds.

In the drawings, T have embodied my invention in a suitable form, but changes of construction can of course be made and elements omitted, without departing from the spirit of the invention.

In the said drawings: Figure 1 is a View of a structure embodying my invention showing the general arrangement of parts and gearing. Fig. 2 is a detail view of the reciprocating sheet turning means, oscillating gripping mechanism, and adjacent parts. Fig. 3 is a plan view of some of the parts shown in Fig. 2. Fig. 4 is a diagrammatic view showing how the sheet is turned. Fig. 5 is an elevation, partly in section, showing the reciprocating carriage and ad j acent elements in the extreme forward position. Fig. 6 is a vertical transverse sectional View through the frame and carriage.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates the impression cylinder of a printing machine, and 2 the delivery mechanism for the same. Interposed between the said impression cylinder and the delivery mechanism are tapes 3, or other means for conveying the sheet. The delivery mechanism comprises essentially a reciprocating carriage 4, reciprocating sheet turning means 5, and a gripping mechanism 6 which may either oscillate or rotate, but which in the present instance oscillates, located extraneously of the sheet turning means and reciprocating carriage.

The gripping mechanism is, in the present instance, constructed as follows: A shaft 7 is oscillated in any suitable way as by means of the gear 8 meshing with the gear 9, mounted on the stud 10, which receives its motion from the segment 11 mounted K011 the stud l2, operated by means of the bell crank 13, attached by means of the rod 14 to the lever 15, pivoted at 16 and carrying the roll 17 operated by the cam 18. The shaft 7 carries a segment of a cylinder 19 carrying the grippers proper 20, pivoted at 21, and normally held closed by means of the spring 22. In this instance, the registering plate 23 against which the sheet strikes is also carried by the grippers 20. On the framework is a stationary cam 2+l. engaging with the roller 25 carried by the arm 26, mounted on the cylinder segment and moving with the same. As the gripping mechanism oscillates, the roller 25 coming in contact with the high surfaces 26 and 27 of the cam, will open the said gripper at the points where the sheet is received and released by the said gripping mechanism.

The reciprocating carriage is operated in any suitable way and runs on the hangers 28 traveling on the framework. The specific means for operating this reciprocating carpresent riage and consequently the sheet turning means comprise fixed racks 29 in the framework with which engage the gears 30 (only one of which is seen) moving with the pinion 31 to which motion is imparted by the sliding rack 32 meshing with the gear 33 which receives its motion from the gear 3st meshing with the rack 35. The rack is attached to the disk 36.

The shaft 7 (and therefore the oscillating gripping mechanism) and the stud 10 are both adjustable by being mounted on the adjustable brackets 37 removably attached to the framework by means of the bolts 38. The segment 11 is likewise adjustable by means of the slotted portion 39 and bolt it). Finally the cam 18 and disk 36 are adjustable by means of the slot 11 and bolt 42.

The shaft 43 which carries the cam 18 and disk 36 is timed so as to operate the delivery once to every two revolutions of the impression cylinder 1, and for other styles of machines once to each sheet printed, or if a collecting cylinder is used, once to every pack of sheets collected. In the present instance, the shaft receives its motion by means of the pinion at, and gears 1-5, as, M, and 18.

On the reciprocating carriage is, as previously pointed out, sheet turning means of any suitable form as the roller 5. This carriage is further provided with a sheet holding means taking the form, in the instance, of two opposed grippers 50 and 51, the latter of which is mount ed on the stud 52, supported by the trans verse rod 75 connecting the two sides of the carriage a, and is adapted to be closed by the fixed stop 53 acting against the arm 51 also mounted on the stud and to be opened by the other fixed stop The operation of the device is as follows: When it is desired to deliver the sheets with the printed side down, the disk 36 is adjust ed so that the carriage 4 is retarded, so thatit will be in about the position shown in the drawings, when the leading edge-of the sheet reaches the grippers. The arm 54 is removed, or the stops 53 and are removed, or the grippers 50 and 51 otherwise rendered inoperative, so that the said grippers will remain open and allow the sheet to pass to the oscillating gripping mechanism 6. The said gripping mechanism 6 will have commenced its movement when the sheet strikes the registering plate 23 and the said gripping mechanism will then, by the means hereinbefore described, nip the sheet and move downward and out of the way of the carriage 4. iVhen the reciprocating carriage moves forward, the roller 5 or other sheet turning means will pass in between the sheet and the gripping mechanism 6, and will turn the sheet over, by pushing against the underside of the said sheet as illustrated in Fig. 4. After the oscillating gripping mechanism has moved about one-half a circle, the cam 2% will open the gripping mechanism and allow the sheet to drop. The gripping mechanism will then move back to its uppermost position by the action of the segment 11 moving in the opposite direction. By this means the sheet will drop with the printed side down on the receiving board 56. To accommodate the different lengths of sheets the brackets 37 and segment 11 are adjusted in the manner previously specified.

When it is desired to deliver the sheets with the printed side up, the parts will be so arranged that the carriage 4 will be in about the position occupied by the gripping mechanism G in the drawings when the leading edge of the sheet reaches the grippers 50 and 51. The stops and 55 are placed in position and the sheet turning means 5 are removed as is also the oscillating gripping mechanism, or the said elements are other wise rendered inoperative. As the recipro eating carriage comes to the end of its return stroke the leading edge of the sheet enters the bite of the grippers 50 and 51, which latter are then closed by the stop acting through the arm 54 so as to seize the sheet. On the forward stroke of the carriage the grippers 50 and 51 will remain closed by reason of the weight of arm 54 so as to carry the sheet with them, and the web or apron fastened with its free end at 58 and mounted on the roller 57 will be drawn out so as to support the sheet. As the carriage comes to the end of its forward stroke the grippers 50 and 51 will be opened by the stop 55 acting against 5st thereby releasing the sheet. On the return of the carriage the apron or web will rewind thereby allowing the sheet to drop on the delivery board with the printed side up.

lVhen the sheet is to be delivered with the printed side down, and consequently has to be turned over, I sometimes find it advantageous to positively remove the sheet from the bite of the oscillating gripping mechanism so that the latter may be free to turn back and assume its uppermost position. This I accomplish by mounting on the reciprocating carriage a roller or a plurality of disks 59 which are normally held out of contact with the roller 5 by means of the friction roll attached to the arm 61 attached to the said roller or disks 59. The cam groove 63 is so positioned that when the oscillating gripping mechanism has moved the distance of a half a circle to its lowermost position, the friction roll will come opposite to the point 6st in the said cam groove which will cause the disks 59 to contact with the roller 5 by the action of the spring 60, thus nipping the sheet between the said roller 5 and the disks 59. As this roller 5 will rotate at a speed which is less than the speed of the reciprocating movement, the sheet will be forcibly removed out of the bite of the oscillating gripping mechanism 6 and the sheet turned over by the cooperation of the roller 5 and disks 59.

The cam groove 63 is located in the cam 66 which is adjustably secured to the framework by means of the bolt 67.

It will thus be seen that when the reciprocating carriage is used to draw the sheet out with the printed side 'up that the sheet is delivered onto the delivery board on the return stroke of the carriage, and that if the sheet is turned over by the means hereinbefore described to deliver it with the printed side down, it is delivered onto the delivery board on the forward stroke of the carriage.
