As soon as the sheet is free of the impression-cylinder, and hence wholly supported by the carrier, the several endless tapes thereof are caused to rotate in a direction the reverse of the bodily movement of the carrier itself, with the result that the carrier will move out from beneath the sheet of paper and allow the latter to drop onto table 7. This rotation of t-he endless tapes is accomplished by a ring or peripheral enlargement 17 on the end of the rearmost cross-rod of the carrier engaging the under side of a contact-plate 18, overhanging one of the carrier-chains. This plate is adjustably secured to frame l by nutted bolts 19, passed through longitudinal slots 20 of a .second overhanging plate 2l, secured to such frame. 22 designates tracks for supporting the chains as they travel horizontally. By adjusting the contact-plate 18 longitudinally the point at which the endless tapes are caused to travel reversely may be regulated to suit stock of different sizes-that is to say, for large stock the engagement of the crossrod with the contact-plate will be postponed, while for small stock the engagement will occur soon after such cross-rod begins its forward horizontal movement.

On the delivery table 7 are adjustably mounted inner and outer gages 23 and a side gage 24. A second side gage 25 is in the form of a bar hinged to a horizontal bar 26, adjustable transversely of the table, the gagebar being held normally vertically or in its uprightposition by a spring 27. Adjacent to this side gage 25 table 7 has a groove or cut-out 28 sufficiently wide to admit the hand of a person to grasp the pile of stock located on the table and to pull the same outwardly to one side, the side gage 25 thereupon being moved downwardly into the groove wherein its adjusting-bar 26 is located. As the stock is thus moved to one side and is free of the side gage the latter will immediately return to its normal position under the action of its spring. By this means it will be noted that the gages retain the stock in proper position as it is piled on the table, and yet permit of its ready removal at any time. The hand cut-out is extended inwardly from one side of the table to and terminates within the field occupied by the stock deposited thereon, which stock extends over such cut-out to allow of its being easily grasped.

From what has been said it will be noted that I have provided means whereby stock discharged from a rapidly-operating printing-press may be quickly and evenly piled on a delivery-table, that its delivery onto the table is effected in a single handling of a sheet or other stock and before the carrier completes the forward movement over the table, and that the point of discharge of the stock from the carrier is controlled by the adjustment of the contact-plate, which gives to the carrier-tapes a travel in a direction the reverse of the bodily movement of the carrier. It will also be observed that the stock may be readily Withdrawn from the table at any time without interfering with the operation of the carriers.

I claim as my inventionl. The combination Wit-h a printing or other machine, of a delivery-table, a carrier movable horizontally over such table and designed to loosely support a sheet during itsmovement away from the machine, and means for automatically arresting the travel of the sheet with the carrier before the latter reaches the limit of its travel over the table for effecting the immediate discharge of the sheet direct onto the table, as set forth.
