SHEET-DELIVERY MEOI H IANISM.

In order to render clearer certain features-- of this invention, it may here be noted that. in connectionwith certain types of'printing' machinerya high speed of output is impera' tively demanded. As an incident of this high speed, it is usually desirable to remove the sheetsin large numbers, and thus means Specification of Letters Patent.

remedied in constructions of the nature of that hereinafter described.

Referring now to the accompanying drawing, there are shown feed rolls 1 adapted to feed a web 2 to a rotary'cutter 3 coacting with an abutment 4 and adapted to sever the web into sheets, which are guided to a sheet path 5. The tapes of this path are preferably driven at a speed somewhat being accomplished by the gearing which is indicated-throughout the drawing in dotted The upper ta es 6 of sheet path 5 7, and the advancing sheet, being speeded up and thus spaced from the following free edge of the web upon entering the sheet path, is thrown toward the upper tape by reason of itsforward edge being curled upwardly by the disposition of the tape rollers 8 and v 9 as shown in the drawing.

Another object is to provide means in connectionwith means of the first mentioned t" e adapted to insure a uniform disposi-- A suitable fly or set of arms 10 is normally held against a stop pin 11, as by the counter balance 12, and is intermittently thrown V downwardly, as by a pin 13 upon a gear 14', Other objects will be in part obvious and thus striking each sheet away from the tapes 6 and throwing the same upon the pile 15 Testing upon a supportor table 16 positioned 'therebeneath. v

The table 16 is mounted so as to be vertically movable, and is provided with a rack shaft 19 which is driven through the worm 20 and wheel 21 from a shaft 22'. The-latter The accom anying drawing is a diagrammember is slowly rotated, as by the ratchet wheel 23 and pawl 24 intermittently actuated from an adjustable crank 25 upon a shaft 26 driven by suitable gearing from the re- Thus upon each sheet being thrown toward the table 16, the latter is lowered throughout a predetermined distance so as to preserve a constant upper level of the pile 15 and hence render its relation to the remainder of the machine substantially uniform.

The edges of the sheets withinpile 15 are justified, as by spring-retracted arms 27 intermittently thrown toward'the pile by cams 28 driven as by the gearing indicated. In this manner the upper level of the pile is not only maintained constant, but the entire of the dropping movement of the table 16.

' desired length by the rotary cutter 3.

The operation of the above described embodiment of my invention is substantially as follows: Assuming the parts to be in the relation shown, the web 2 is continuously fed by the rolls 1 and is cut into sheets of the vious to the severing of the web, its forward edge has passed within the bite of the sheet path 5, and hence a slight tension is placed upon the web, which facilitates the cutting thereof and assures the snapping ahead of the severed sheet and its proper spacing from the forward free edge of the remainder of the web. The sheets are each in turncurled toward the upper tape 6 by reason of the disposition of the rollers 8 and 9 as above set forth, and this upwardly curled free edge tends to maintain the advancing sheet against the tape 6, from which it is thrown, as by the fly 10, u on the pile 15. As above set forth, the tab e is preferably lowered at a rate substantially equal to that at which the sheets accumulate thereon, and a constant upper level is thus maintained. The justifying arms or joggers 27 act, as above set forth, to maintain the sheets in proper registering position 'with relation one 'to another.

It will thus be seen that a pile of any desired height may be accumulated upon the table 16, and that the upper surface of thispile will maintain a constant relation to the fly 10 as well asthe remaining parts of the machine. As the upper portion of the pile, moreover, is constantly tapped into the desired form, the entire pile, even when ex tending beneath these parts, will be in'orderly condition and ready for removal and packing or any other desired disposition.

It will thus be seen that I have provided apparatus in which the objects of my invent1on are attained and the above enumerated advantages are, among others, present in a high degree.

The entire apparatus is of the simplest and most positively acting character, and is well adapted to withstand the high speed of running which is desirable in machinery of this general type.

Certain features herein shown and described are shown, described and claimed-in my co-pending application Serial No. 303,359 filed February 28, 1906, and accordingly are not claimed herein.

As many changes could be made in the above construction and many a parently widely different embodiments of tffls invention could be made without departing from Predownwardly from said upper tapes claim as new and desire to secure by Letters Patent is:
