DRYING APPARATUS FOR PRINTED SHEETS 0F PAPER.

Specification of Letters Patent.

Patented Aug. 2"?, 1912.

Application filled October 18, 1911. Serial No. 655,369.

and useful Improvements in Drying Appa-l ratus for Printed Sheets Vof Paper, of which the following is a specieation.

This invention relates to improvements in devices for facilitating the drying of freshly printed sheets of paper.

It is well known to those skilled in the art that the time required toactually dry the average printing ink is .from siX to twelve hours, but. that if properly exposed yto the air said sheets may be dried in'a much shorter time sufficiently' to allow the placing, of the same, oneupon the other without the ink thereon osetting.

v The object of the invention is to provide an apparatus which is adapted to receive the printed sheets of paper direct` from the printing instrurnentalities and hold said sheets in a substantially horizontal. plane while conveying them slowly into and through a heated chamber' where 'they are retained a sufficient length of time to permit the ink thereon to set or to dry, after which they are placed upon the delivery table of the press Without disturbing t-he sequence of printing. I

The object is still further to provide an apparatus for drying printed sheets of paper which is so constructed that it may be placed above the delivery table of a printing press structually` independent therefrom and occupying but very little more floor space than is occupied by the ordinary delivery mechanism of said printing press, and furthermore, said apparatus may be moved from one press and used on another press without material change in the parts.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof, but is notintended to be liniitedto the particular construction of elements hereinafter described as it might be embodied in other forms and devices differing from those hereinafter described by such variations' therefromas would necessitate merely the exercise of lneehanical skill. n

Like numerals refer to like parts in both views/of the drawings.

Referring to the drawings: VFigure 1 is a longitudinal sectional elevation of an apparatus embodying my invention. Fig. 2 1s a sectional plan view of the same taken on the irregular line 2-2 of F ig. l.

In the drawings, 5 is a portion of the frame of a printing press upon which a delivery table or sheet receiver 6 is placed. A paper carrier 7 consisting of endless belts 8, 8l isA also mounted upon said frame 5 and is adapted to receive sheets of paper directfrom the printing instrumenta-lities9.

Located above and adjacent to the `delivery table 6 and carrier 7 is a paper conveying device 10 mounted upon frames 11, 11 structurally independent from said printing press and` embodying in its construction racks 12, 12 arranged in tiers 13 and 14. The racks 12 are provided at each end thereof with

frames

15, 15 each of said frames adapted to engage and support another' frame o-f like construction. The frames 1.5, 15 are connected together by a shaft 16 upon which`- are mounted a series of

brackets

17, 17 having secured thereto

sticks

18, 18 upon which the sheets of paper are held, suflicient space being provided between the sticks of one of said racks and the brackets of the adjacent rack to allow lthe sheets of paper 31to rest upon said sticks without contacting with said brackets.

Grooves 19 and 20 are provided in each of the side frames 11, l1 thus constituting guides adjacent to the

end frames

15, 15 of the tier of racks 13. Projections 2 1, 21 extend laterally from each of the frames 15 and project into the grooves 19, while the shaft 16 projects lthrough the frame 15 forming the projections 22, 22 which engage the other of said grooves 20, 2.0, said projections 21 and 22 serving to guide said racks'upwardly in a substantially horizontal position.

Detents

23, 23 pivoted to the side frames 11, 11 engage the lowermost rack in said tier of racks, thereby supporting said tier and retaining the same within said` grooves.

Grooves

24 and 25 in the side frames 11, 'l1 also constituting guides, are provided adjacent to the

frames

15, 15 of the tier'ofrracks 14. The grooves 24 are engaged by the projections 21 of said racks and the grooves 25 are engaged by the pro# jeetions 22, said

grooves

24 and 25 serving to guide the racks downwardly or laterally relative to the sheets of `paper carried thereby and toward the delivery tabley 6. The

grooves

24 and 25 terminate at their lower ends in semi-circular grooves 26 and 27 which check the downward movement of 5 said racks. A groove 28 connects the upper ends of the grooves 19 and 20 with the upper ends of the

grooves

24 and 25 andv a groove 29 connects the lowerends of the semi-circular grooves 26 and 27 with a recess 30 to which the lower ends of the grooves 19 and 20' are connected. 'Anelevator 32 is pivotally mounted within the

recesses

30, 30 upon links 33, l33 at each end of said .elevator and adapted 'to guide said elevator horizontally across a gap 72 between the end of the groove 29 and the lower end of the grooves 19 and 20, said gap being provided for the purpose of allowing more space in which to feed the sheets of paper onto said racks. A suitable mechanism is provided, as hereinafter described, to circulate the racks 13 upwardly 4along the grooves 21 and 22, thence horizontally along the groove' 28, which is substantially parallel with the sheets of paper carried by said racks, thence downwardly along the grooves -24 and 25, grooves 26 and27, and horizontal groove 29 to the elevator 32, and from thence upwardly into said grooves 19 and 20.

To prevent the projections H21 from dropping into the grooves 20 while the racks 13 are being moved along the groove 28,

switches 36 are pivoted at 37 to the side- Mframes 11`and swing upwardly allowing the wardly and out lof the grooves 20, but immediatcly dropping back into place in time to bridge said grooves to guide said

projections

21, 21 thereacross. To prevent the projections 22, 22 Ifrom dropping into the grooves 24', said projections are extended bef yond the projections 21, thus requiring the

grooves

20, 28, 25, 27 and 29 to be cut deeper than the grooves 19 and 24-and causing a ledge 38 to be formed at the upper end-0f the groove 24, said ledge guiding said projections 22 past the entrance of said grooves.- I preferably employ. acoperative actuatingv mechanism to circulate said racks along the hereinbefo're" described grooves, said, mechanism embodying in its constructiony a shaft 39 to which a rotary motion is imparted by any suitable means capable of im- 'parting thereto a speed which shall circulate said racks and present the same one at a time to the delivering means ofr the device from which the sheets of material areto bereceived synchrondusly with the delivery of said sheets ofjmaterial which are also fed one at a time to said' delivering means. Sprockets40, 40 secured -on said shafts are connected through

chains

41, 41 to

sprockets

42, 42 rotatably mounted upon studs-43, 43

- secured in the said frames 11, 11. y A sprocket 44 -is secured' to one of the sprockets 42 and 1s connected by a chain 45 to a sprocket 46 rotatably mounted upon a stud 47. A gear 48 is mounted tol rotate in unison with the sprocket 46 upon the stud 47 and engages another gear 49 which, with a sprocket 50, is secured upon a shaft 51 journaled to rotate in said frame. Said sprocket 50 is connected bya chain 52 to a sprocket 53 on the shaft 54, said shaft being journaled to rotate in said frame. been guided along the

grooves

29, 29 to the elevator 32 and into the position against a stop 3 2, is arranged to receive a sheet of paper 31 which is fed from theprinting instrumentalities 9 by the

endless belts

8,18 of the carrier 7 and along the sticks 18 of said racks, to the stops 64, 64 mounted upon the rod 65.

A rocking movement is imparted to the elevator 32 by the camlevers 34 engaging A yrack 55 having previously i studs 56, 56 at eachend, respectively, of said which are rotated upon the

studs

61, 61 by gears 62 secured to said cams, respectively, and which, in turn, are rotated by

pinions

63, 63, respectively, fast to the shaft 39.

As the tier of racks 13 is moved upwardly or laterally relatively to the sheets of paper carried thereby, the' projections 22, 22 upon the upper rack are moved into the path of

pins

66, 66 b y" which said rack is transferred from the tier 13 along the grooves 28 to the tier 14,-while the lowermost rack in the tier 14 is engaged by pins 67, 67 which move said rack along the grooves 26 and 27' and into and through the groove 29 to the elevator 32 and against the stop 32", and while passing along said grooves 29 the papel; thereon is transferred therefrom to the table 6 by

lingers

68, 68 secured upon a rod 69, said frames 11, 11 and in'closes the top and sides y of said paper conveying'y device and heating devices 71, 71 are provided which heat the air within said chamber through which said sheets of paper are conveyed. v

The general operation' -of the devlce 1s as follows: The sheets of paper are fed from the impression cylinder 73 of the printingl instrumentalities by the endless belts, 8, 8

into `the gap 72 ,against the stops 64 and upon the rack 55, while said rack rests upon the elevator 32. As the cams`60 are rotated, the levers 34 are rocked upon their

pivots

35, 35 to'move the elevator upwardly, thus transferring the rack 55 from its position shown in Fig. 1 to the position .occupied by the lowermost rack74 in the tier of racks 13, in which postion it is heldby the

detents

23, 23. As the rack 55 enters the grooves 19 and 20, the tier of racks therein are moved upwardlv the space occupied by one rack, and the uppermost rack 75 in said tier of racks is carried into engagement with the pins 66 upon the chain 5 2, whereby said rack is transferred from the tier 13 v alon groove 28 to the top of the tier 14. Simultaneously with the novement of the rack 75.l the lowermost rack in the tier of racks 14 is transferred from said lowermost position by pins 67, 67 upon the chains 41 through the grooves 26 and 27 into the grooves 29 and along said grooves to the

stops

68, 68 which check the movement ofjthe sheet thereon and thereby transfers the sheet from said rack to the delivery table 6. Said rack is then moved along said grooves 29 to 4the elevator 32 and into position to receive another sheet of paper, and so 0.11,l circulating intermittently upward into the heated chamber inthe casing 7()l and being retained therein a sufficient length of time to allow the heat to permeate said sheets and dry the ink thereon. The rack is then moved downwardly to deliver the sheet to the delivery table in its proper sequence, and is then moved back to the receiving position.
