a c itizenof the UnitedStates, residing in l Lubes, inthe County of lVashington and Stateof Maine, haveinvented anew and useful Improvement in Driers and Feeding j lDevices forCoated or Lithographed Sheets or the like,r of which the following is a speci- This invention relates ingeneral to driers and feeding` means therefor for coatedv or lithographed sheets or the like. i Prior to my invention it has been; gener- `ally the custom toloeatethe drier `just 'bef yond the delivery table of a coating or litho-l graphing press. TheseV driersv'are ordinari-ly Y provided Wit-h two orl more oonveyers which vmove through ,the heating., chamber and 'hieli carry the'plates to dry .the coating. In order that the driers may take up, as

.little space as possible and yet have' theydeis'ire'd c apaoity,the Conyeyers are provided Vwith. racls which carryftheV l plates standing i on edge.

Prior to my invention: it has bee-.inly generallyv ther customV to `transferftlie plates from the pressjto the racks of the drier manually,

i tivo attendants'beingl positioned betWeentlie two?piecesfofapparatus. each Ytaking alternate sheets and. depositing" them ,in v the rac-ks'.- Thisgmanual feeding is objectionable not only beacuse of` the Wages necessarily paid the twoemployees but also of thediii-` culty vof preventing' ther manualr handling from marring the sheets or plates. s'the sheets aifedelivered Vfrom the press the" Coat'- ingorlithographing is yet and. any finger printsupon the plates are permanent. y

Referring to the drzwvings7 AThe :ti'eedingv leviee shoiv'n on the drawing lis 4'adapted to receive coated or lithographed sheetsfrom a conveyer 1 forming a partof the printing press and'ieeeiving the plates suitable side guides 5 forniaintaining the plates in aceurate position being also provided.

power (not shown) imparts motiony through "-.be'vel gears 12,' 13to asliaft Mlinounted in bearings 15 and 16 onthe legs T and 8. These bevel' gears arel held l'in'` mesh by a spring 17, indicated in Fig. 6. The shaft 14 carries a main drivin y spi'ocket 18 (at the 4left of Fig. 2 and rig it of Fig.` 6), and

Vthis main driving sprocket 18 through the agency of a sprocket chain 19 imparts movement to two sprocket wheels 20 a1id21. The sprocket wheel 20 is carried by a shaft 22 extending clear across the feeding mechanism and having bearings on the tops ofthe legs. The shaft 22 also carries a sprocket 23 which engages adrive chain 211 taking over and driving also a sprocket wheel 25 upon a shaft 26 having bearings 27 and 28 whichV may be attached to the main frame 29 of the baking oven or drier 30. The shaft 26 carries two sprocket wheels for the Vchains of what may be termed the feed conveyer. One of these sprocket wheels'31 is engaged by the chain 82 which takes over ay l sprocket whee 33 Vupon a shaft 34' mounted lin bearingsy 35 in the leg 8, and the other sprocket wheel 36 at the other side of the feed conveyer engages a similar chain 37 taking over a sprocket 38, the driveat one sidebeing substantially identical with the drive at `the other. The two chains 82'and Y 37thus inove in unison and they are .con-

nec-ted at appropriate distances Vby cross members 39 from which propelling pins or fingers 10 extend outwardly. The bearings 85 are mounted in guides 35 (Fig. V1) and may beheld in adjusted position in said guides by any means well 'known for "the purpose.

A slotted guide or supportfilis mounted above the upper travel ofthe feed conveyer and the pins or fingers 10, move throughV the slots of this support. The suppoit inthe present instance consists of a plurality of bars having curved upper faces supported at one end by a cross member L12 attached to legs 7 and 8 respectively, and at the other end by cross member e?) secured to brackets ed and 475 which also serve to hold up one end of the side guidesor guards 46 and 17.

The sprocket 21, already mentioned, and

which is driven by the sprocket chain 19,V

"a7 through brackets 57 and 58. The rods 53 are connected with pushv finger carriers or blocks 61 and 62. 1 p

These blocks are adapted to vslide and reciprocate transversely of the feeding device, beingguided in their movement by a bar 63 on which they are fitted. carries a push finger 66, 67, `(one'of which push fingers is shown 4in enlarged elevation Each block ypins 66', 67 It will be noted that, the faces 6,9 are verti-cal'and that springs 71 tend to pull the pushV fingers66 Y and 67A toward and into engagement with Vthe faces 69, which is their-operative position. y i

The push fingers 66 and 67 carry pins 72,

73, which are adapted to engage guides or Y bars 77 and 78Y to hold the fingers in the position shown in Fig. 8 during the inoperative periods of saidfingers. The two bars 77 and 78 are pivotally inountedat 79 and 80 on a cross member 7 4, which is secured to the side guards 116 and 47 by means of brackets 75 and 76. vTwo posts 88 extend up from the bar 7st and through springs 8st tend to maintain the bars 77 and 78 in the lowered position shown on the drawings and in en# gagement with lthe upper face of thebar 71. rlfhis arrangement leaves the bars 77 and 78 in substantially horizontal positioin'the ends 81 and 82 being curved downwardly, as shown, to'engage the bar 74. i Y The cams 51 and 52 produce continued oscillation ofthe bars or levers, 58 and these in turn cause the blocks or push'inger car'- riers to reciprocateacross and abovethe feed conveyer,V The 'printed plates are'de-V livers-d insingle lile arrangement Vto Vthe center of the conveycr, as jmay be' seen by vieuf'ing'F ig. 2, andare there pickedupfby the pins 40 extending between the VbarsV 41. l/Vhen the platesparrive beneath the reciproV- eating pushngers they Yare marshaled into Vindependent files in the present instance being divided into two files, one on each side ofthe center of' the 'conveyein Each push finger engages the sides of alternate plates and moves it transversely as it is carried` forward by the coiiveyer. Thetwo push fin- Y gers move together, one being always idle in vthis embodiment of my invention. The idle finger is disposed above the plate being acted upon by the active or operative finger and in order that this idle fingerinay not contact with the'top of the plate to mar the coating, arrangement is provided to hold it elevated. ThisV arrangement consists in the bars 77 and 78 :and pins 72 and 7 3. When feach push carrier block and its finger completes an operative stroke, either the pin 72 soon engages the: down-turned end ofY tliebar 77 or theV pin 7 3 engages the down-turned end of the bar 7 8.` i The respective actionscf these pins s and bars are identicaland l'will describe the action with relation to thepin and bar 78. As soon as the pin 7 3 engages the downturned end of the' bar 78, the 'pin is lifted and the push finger swungr about its push pin 67 and. into the position occupied by the push finger 66 in this figure. The push The movement offthe blocksito each side is f finger G7 then stays elevated `until thenext succeeding platehas been moved tothe right, viewing this figure, by the puslrfinger 66.

passes from underthe influence of the push r`finger somewhat .before the push finger carriers havereached the end, of their sidewise 7 travel; After the plates have been carried y in part atr 96. The carrier 95 carries racks S8' spo outof engagement with thepush lingers,

continued movement of the blocks brings thev pin 72 or 7 3', which is riding upon the guide or bar 77 or 7 8', opposite or above a recess 85, shown in Fig. 2. The elevated ipin drops through this recess and permits they vfinger it controls to assume av verticalv position unf.

der the action ofv the appropriate spring 7l.

In other words, viewing Fig. 3,v continued movement to the leftr of the blocks 6l and V62'is accompanied by a breakingfo'f the centact between the plate 'and push finger 67 and then a movement' of the'push finger 66 tovvertical posit-ion. After the pin hasthus dropped through the recess 85," it passes under theguide 7 and returns iii-vertical position ready to engage the side ef the next succeedf ing plate, at which timethe push finger 67 will have been moved to inoperative position by the bar 7 8. After'dropping through the Y slot thepin is preferably the plateor'crossmeinber 74. v`The coated or lithographed plates are thus into independent files, from which they proceed through kthe continued action'of the conveyer vand eventually` their upperrends en-v counter a chute or guide 8G whichis-inclined upwardly `from the delivery end ofthe feed conveyer at ra sharp angle. ViewingFig. l

it will be Anoted that a Vdrier conveyei" ,95

passes through a heating Y cl'iamber. indicated which are inclined forwardly in the direction of travel of the conveyer. The arrange?, nient of these racks isfsuch that'the plates may be closely stacked'y and yet prevented from having their coated surface come in contact with either the racks or the'neXt Aad jacent plate.
