. pulley 19"L without disengagement therefrom. lVhen the drum 13FL is to bev again f.

rotated by the duplicator P the belt` 18 is replaced on the idler 18h;

The delivery relation of parts shown in Fig. 2 includes a removable receiving tray 21 that may be 4supported from one or bothof the members 10b by suitable rods 22 erother wise. The tray 16 is positionedabove the members 1()b on suitablesupports 17; The drums ln'and 14 with their attached heads respectively 13 and 14 are positioned between the standards 41()a with their shafts or spindles .13 and 14@e in the bearings 23 and 23?.`

The operation of my device is extremely simple. As the printedsheets are delivered -tangentially from the duplicator l?, indicated at as Fig. 1, they fall on the band 15a on ahorizontal plane within the sides of the tray 16, andtare then successively carried by the band' 15ans it is wound at 13b on the drum 13a, the reserve portion of the band 15av being ltaken from the roll of paper 14h from offy the idling .drum 1aa untilit isentirelyvfreedfrom the latter drum. When the printed sheets have remainedon the receiving roll long enough to become dry the free end of the band'is passed around-the idler 12in its new position, shown in Fig. 2, andthen fastened to the drum 14ab in any well known manner. VrIhus seeuredthe band iswound konto the drum 14s"L byy means of a handle20removably attached to the outer end of the shaft 14? of this drum. As the band is wound onto the druml 111a from off the drum 13a the printed sheets are delivered vfrom the idler 12 at g/ onto the receiving tray Shouldit be found desirable tomake the drums interchangeable I may use whatever eXpedients arel found necessary to accomplish this purpose. I am aware that bands of porous p aperhave been used with winding rolls for` slipsheeting purposes, but do not know that my arrangement of parts cooperating with the rolls or drums have been used heretofore, and that by reasonof `Suchfrelation 4I` secure Anew results ofgreat practical value withoutrecourse to .expensive and complicated equipment.' i What I claim is: e Y 1'. In slip sheeting devices, a frame, a pair of reversible paper holding rolls supported on the frame, aband of porous paper in attachablel and detachable engagement with the rolls on its one face, an idler adapted yto engage the band on its opposite face, and

means for supporting. the idler'in different positions on the frame parallel to the rolls in accordancelwitli Vchanges in direction .of movementof the band.l

2. In a slip sheetingdevice, a pair of reversible paper holding` rolls, an idlingoller iii-.parallel relation to the rolls, a frame for supporting the rolls, means for supporting theidlingfroller in different positions on the frame, and a band of porous paper in engagement witlr the rolls and the idling roller on its opposite faces respectively.

In a slip `sheetii'ig machine, a frame, the combination with a duplicatinggmechanism, of a pair of paper receiving` rolls supported in parallel relation to each other on 4the Y frame and reversible in' respectof lthe rotation` of the duplicating mechanism, an idling roller, means for supporting the idling roller indifferent positionson theframe between the paper` receiving rolls and the duplicating mechanism, anda band lof paper engaging the rolls andthe idling roller respectively on itsopposite faces. l

1; In a slip sheeting device, a duplicating device adapted to successively imprint separate sheets of paper and deliver such sheets in orderly sequence!independently ofeach other, comprising aframe, aband of porous paper adapted to receive the sheets'onv its one face, a reversible roll supported onA the frame for winding thereon the bandofporous' papera reversible roll also supported on the *frame` for` unwi'nding the paper therefrom, means for rotating thev winding rollin unison with the duplicating device, and means comprising an idling roller adjustableon the frame to differentv positions for. holding the. band of paper substantially its other face, andmeansfor moving the paper in' an opposite 4direct-ion to` wind it onto they-other roller.

6. rl`he combination. with a the lilie,.of a slip sheeting attachment comT prising a frame carryingiv avtdrun to be driven fromA saidlduplicator, an. idle drum vsupportedon theframe, guiding means adjustable to different positions on the frame, and a flexible band of porous paper traveling from the idledrumtothe drivendrum Vover said guide means and. forming. a moving support-adapted to successively receive duplicator or' -iio ' and feed the sheets from said duplicator onto said driven drum and envelope them between the different layers of the band as the latter is being rolled onto the driven drum. A

7 The combination with a duplicator or the like, of a slip sheeting attachment comprising a frame which consists of an upright for carrying said drums and a horizontal part carrying the guiding means 10 adapted to be placed in different positions on the frame which is capable of being supported by the support of said duplicator so that the sheets dropping from the duplicator will be received by said band on a 15 horizontal plane.

In testimony whereof I aiix my signature.
