To (r53 whom is may concern:

Be ii; known that LTNILLIF; K: Hose-crew, a citizen or" the. Uni ed Stores, and a resideni; of Taunlcon,- in the county of Brisiol and fi ters of Massachusetts, have invented an. improvement in Sheet-Piling l iiecbanism for Frintiriglresses, of which the iollowing descripiion in connection with illfifi so compenying drawinggis a specificeiiou, like characters on the drawings repr se-erasing l ke This einvention relates the mechanism for printing presses le-rly 'lomeans to preveni freshly she ts from offsetting. 4

order that the principleoi this invenon may be readily unde ood, l: have dislosei s, single embodimci thereof 1n the --i:compenying drawings, wirerejn- M I Figure l is a side elevs printing J03 having my invenlzion a L d thereto; is s plan view of mechanism s eel: piling printed D I I 4 J iown in Fig. and.

The object of inyrinvenri' n 'prevmtfreslily printed sheets from offs-cf being acciunulated in u ole-y icing u on the slicers not then i i, 31 static electricirywiili winch in: sheets have becorlie charged being caused by the i wnen passii illlioufillflw press and which causes tliei'n to roger-her when beingpiled.

collie disclosed embodiment of on I ecciunplisli myobject by in Lug suieable gaseous matter preferably jet ' air and preferably in a heated condilion between the freshly printed sheets as they are being piled, such gaseous matter floating unddr" .g the sheets and dissipating any in lcctricity. 1'. shall iliroughoui; the

2 e icstion and claims employ the term i in a generic sense inincludcany suitzitruosuiieric air is employed for the purpose.

have shown my invention applied ;sisndcrd two revolution ed and cylinrinizingprcss, but I desire i". to be on cod "chill; the invention inc desired fiype of primer pro v livery of the fly type or a pri sud partied and lare enfollowing" mechanism: .l c guseous marker. Preferably, however,

any kind of delivery, as, for example, a de nted side up delivery. Y Referring more particularly to the drawings, I have herein. represented a press of the fly type of delivery, the fly being represented at 1 and being adapted to receive the printed sheets in any suitable manner from the printing mechanism proper.

Iprei'crably provide a sheet piling box to' receive the sheets from the fly 1.' I have herein. represented the piling box as having a fixed side 2 suitably connected as indicaied l; 3'3 to the side frames 4 of the press and an adjustable side 5, the ends Whore-f are secured by screws 6 adjustable along longie tudinel slots? in the said side frames, thus permitting. she side &0 be adjusted toward and from the side 2 to accommodate difi'erout; sized sheets. The sides 2 and 5 are notched as iudicar/edat 8 to receive adjustable ends 9 't-lulis permitting transverse adjustrneni of the sides of the box. vThe sides and ends of the box should be so positioned and adjusizec-as to sm'round and substerr ciully fiiilie sheets-piled ,therein, thus preveniing the from freely escaping between the last few sheets, and thereby flout-c ing' or separating the sheets inia measure sud giving the ink thereon an opportunity to dry before she weight of the accumulating slicers is suilicicnl; so expel all of and rho cause offsetting to occur.

lpreferably provide a vertically movable bottom or piling board 10, which issupplied with supporting means (not shown) whereby it forms the bottomof the piling box when in its upper position and can be grad uall'y lowered as the pile accumulates and is finally landed on a truck. Any suitable or usual means co-acting with the piling board 10 maybe employed.

the air While 1 may employ any suitable means foo introduce air between the sheets as they are being piled, Ipreferebly provide the v provide a suitable blower 11 driven by belt 12 frame pulley 13 upon shaft 14 and which may be any suitable she-fl:v of the printing mechanism, or if desired the blower may be driven fromsome external source of power. From the blower extends a, pipe 15 herein represented as having an up ending portion 16 ex'tending'to the plane or the piling box and a horizontal;

piled sheets having means temporarily to confine the entrained air beneath a sheet as itis-received by the receiver, and co-acting ,means to discharge a jet of air wholly beneath the said sheet while it is being so received.

5. In sheet piling mechanism for printmg presses, sheet piling means to pile sheets.

In a sheet piling mechanism for print ing presses, a piling box substantially fitting sheets piled therein in superposed alinement, means to depmit'printed sheets in superposed alinement in said box, whereby air is entrained between the sheets, and means distinct from said piling means to discharge a jet of air wholly beneath a sheet as it is received in said box.

' y 7. In a sheet piling mechanism for printing presses, a piling box having a bottom and substantially fitting sheets piled therein in superposed alinement, means to deposit printed sheets in snperposed alinement in said box, whereby air is entrained between the sheets, and means distinct from said piling means to discharge a jet of air wholly beneath a sheet as it is received in said bore 8. In a sheet iling mechanism for print- .85 ing presses, a de ivery table having means to receive and retain sheets in superposed alinem'ent, sheet piling means to, deposit the sheets in such superposed alinement, means distinct from the sheet piling means-to dis- '4c charge a jet of air whollybeneath the sheet as it is thus deposited, and means to move said j et discharging device undeineath the depositing sheets temporarily to support the sheet that is being deposited and then '45 to withdraw said jet discharging means.

In a sheet iling mechanism for print- .ing presses, a elivery table having means to receive and retain sheets in superposed alinement, sheet piling means to depositthe sheets in such superposed alinement, means distinct from the sheet piling means to discharge a jet of airwholly beneath a sheet as it is thus deposited, and connectionsto effect an intermittent discharge of air through said air discharging means, and to move said means underneath the depositing sheets as each is being piled by said sheet pilingmeans thereby temporarily to support each sheet as it is being deposited and then to withdraw said air discharging means.

10. In asheet iling mechanism for printinlg presses, a d ivery table, co-acting sheet a p' ing means, means to discharge a jet of air wholly-beneath the topmost sheet as it is deposited upon previously piled sheets on intermittently; "intthe delivery table, and means to move-said 1 jet discharging means into and out of the F path of the piled sheets.

11. In a sheet piling mechanism for'printing presses, a delivery tab1e,,co-ac ting sheetv piling means, an air jet discharging device coiiperating therewith, and connections to effect an 1 intermittent discharge of air through said device and to move said device the path of the piling sheets and temporarily to support'each of said sheets as it is being deposited, and to withdraw said device from said depositing-sheetsupporting position.

'12. In a sheet plling mechanism for printv ing presses, a delivery table, co-acting'sheet piling means, an air jet discharging and depositing sheet supporting device coiiperating therewith, a valve controlling the flow of air therethrough, a shaft, and'connections from said shaft intermittently to operate said valve andintermittentl to move said device into the path of-the piling sheets and into depositing-sheet-snpporting position.
