j .,@39SL Specification of Letters Patent. Fatenhgd Jan. 14 1913.

Application filed May 1-5, 1911. y Serial No. 627,238.

To all 'whom it may concern Be it known that I, WiLLiAM A. SPURRIER, a citizen of the United Statesjresiding at Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful 'Improvements in Drying Apparatus for Printing-Presses,- of which the following' is a specification.

This 'invention relates to an apparatus for drying freshly printed ink upon the surface 'of sheets of paper and is also adapted to dry sheets of paper whether the same have ink freshly 'printed upon their surface or not, the same being adapted to dry sheets of paper or to season the same in readiness' to be used in printing and lithographing.

The object of the invention is to dry the sheet of paper and the ink thereon, either' or both, as the same is passing from the impression cylinder of a printing press to the receiver or frame, in which the sheets are placed one by one by suitable delivery mechanism well known to those skilled in the art. In general, to accomplish this result the apparatus of my invention embodies holding sheets .6 is the type bed.

T, 7 are inking rollers.

A reciprocatory motion is imparted to. the type bed 6 and a rotary motion is imparted to the impression cylinder 5 in a manner well known to those skilled in the art. The sheets of paper 8 after being printed 'pass from the illustrated in Fig. 3.

he. iingers 15, 15 are fastened to a rock shaft 16 to which a rocking motion is imparted by suitable mechanism, not shown in the rawings,.but well known to those skilled erate paper through an air chamber in which the air is heated, preferably by electrically heated tubes, and finally delivering the said sheets time to va suitable receptacle, the apparatus ngers l5, l5 are a pivot 152, ngers constituting stop fingers to prevent the sheet 8 from returning with the carrier upon the return movement of said carrier. Said fingers are rocked from the position illustrated inFig. 2 to the position illustrated in Fig. 3 and vice versa suitable mechanism skilled in this art at the sheet 8 and also at the pro sheet 8 as it is broug rier.

A reciprocatory motion is sliding frame 11 the pile of sheets on the delivery table and upon both surfaces of the sheet.

rifhe invention consists in the combination and arrangement of parts set forth in the following specification vand particularly pointed out in the claims thereof.

eferring to the drawings: Figure l is a plan View of an apparatus embodying my invention. Fig. 2 is a sectional elevation taken onV line 2-2 of Fig. 1, illustrating in addition to the arts shown in Fig. l the impression cylin er of a printing press and the type bed thereof, the same being broken 18, 18, the rocker away to save space in the drawings. Fig. 3 arms 18 being pivoted at 19 to the frame 20 is a sectional elevation, similar to Fig. 2, of the machine and ha'ving'a rocking moveer .time to clear said t forward by said carh are connected at frame and at the illustrating the parts in different relative poment imparted thereto by lmks 21, 21 which sitions. f 'Y are connected to a suitable mechanism to Like numerals refer to like parts throughimpart a reciprocatory motion thereto out the several views of the drawings. whereby the rocker ai ms 18 are given'a rocklinks 17, 17 a In the drawings, 5 is the impression cylinder of a print-ing press.

An apparatus for drying sheets of paheater member 30 being above the sheet and per and the ink thereon, having in combinathe heater member 3l being beneath the tion, a holder and a receiver for said sheets, sheet, and further that-as the sheet falls into the receiver 2-, it falls slowly, the frame inclosing the hot air under the falling sheet and retaining said hot air for a considerable period, thus causing the sheets to rest upon heated air as they fall into the receiver a hood on said carrier adapted to extend sheet carried qthereby, a heater member on said carrier beneath said hood,- another hood located above said receiver, and mechanism adapted to move said carrier to and fro beneath 4said last named hood between said holder and said receiver.

n apparatus for drying sheets of paper and t-he ink thereon, having in combinat-ion, a holder and a receiver for said sheets, a carrier adapted to carry said sheets one by one from said holder to said receiver, a plurality of heater members on said carrier, one of said heater members located above and the the sheet held on said carrier.

4. An apparatus for drying sheets of paperl and the ink thereon, having in combination, a receiver for said sheets of paper, a hood located above said receiver, a battle plate extending across said hood, a carrier adapted to deliver sheets one by one to said receiver, a heater member on said carrier, and mechanism adapted to move said carrier to and fro beneath said hood.

5. An apparatus for dry-ing sheets of pabeing pressed closely against the second sheet from the top when it descends into the receiver. In this manner, the heat is applied to both sides of the sheet,

the heated chamber 25 andalso when said sheet enters the heated chamber 39 during its'forward movement and as the sheet settles after leaving the carrier the defiector throws the heat from the chamber down upon the freshly printed surface of the sheet, thus giving a continuous application of hot air to the top and under surface of the sheet from the time that it leaves the tapes 9 unt-il it is delivered into the receiver 22 and finally settles down upon the sheets which have been previously delivered to said receiver.

lVhile I have described the chamber 39 as per and the ink thereon, having, in combina' 100 covered by a hood 36, with a baiile plate 38 tion, a receiver for said ,sheets of paper a at the front end thereof,and the chamber 25 carrier adapted to deliver sheets one by one as covered by a hood consisting of a top 26 to said receiver, a hood on said carrier, a and battle plates 27 and 9S at the tiont and battle plate extending transversely of said rear ends -of said hood, respectively, and hood, and a heater member on said carrler while I prefer this construction for -conbeneath said hood. ining the heated air, both within the cham- 6.

Such a device Would come thereof, respectively, and a heater member within the meaning of the term hood as on said carrier beneath said hood. 115

employed in the foregoing specification and in the following claims, for such a device would confine the heated air above the receptacle 22 or above the sheet While it is held upon the carrier l0 and would, therefore, perform the same function as the cifically formed hoods which I have scribed, although to a less extent.

IVhat I claim and desire by Let-ters Patent to secure is:

1. An apparatus for drying sheets of paper and the ink thereon, having, in combination, a holder and a receiver for said sheets, a carrier adapted to carrypsaid sheets one by one from said holder to said receiver,

'1. A printing-press having, tion, an impression cylinder, a receptacle for printed sheets, mechanism adapted to carry said4 printed sheets one at a time from said cylinder to said receptacle, said mechanism embodying a carrier, a hood on said carrier adapted to project over a sheet carried thereby, there being an air chamber therebeneath through which chamber said sheets p while being carried from said cylinder and deposited Ain said receptacle, and means adapted to heat the air in said chamber.

8. A printing-press having, in combination, an impression cylinder, a receptacle for printed sheets, there being in combina` esV an air chamher located above said receptacle, means adapt-ed tu heat the air in said chamber, means adapted to confine the air so heated above said receptacle, mechanism adapted to carry said printed sheet-s .said eylindeii' through said Chamber to said receptacle, said mechanism embodying a carrier. a hoed whieh chamber sai one by one from l 1 sheets pass while being carried from said. cylinder and deposited in said receptacle, and means te heat the air in said last-named chamber.

In testimony whereof 1l have hereunto set my hand in presence of two subscribing Witi nesses.
