Referring tothe severalfigures of the drawing," in .Which corresponding parts are indicated-by the-same reference characters,\-+' l0 and. 11 indicate. folding rolls of. any approved type revolubly mounted inoperative v i 1,766,083 N relation to each other upon "a framework not shown, such rolls being in such position with respect to a printing presses to receive a series of papers downwardly therebetween. Guide bars 12 of usual type are mounted in position below the folding rolls lO and 11,

' with the upperend portions of such guide bars extendinginto'grooves 13 formed in the 1 'face'of the folding roller 11 in the usualmanfinerxsolas to permit the paper's passingcbe tween the folding rollers topass downwardly along'the faces of such guide bars. A deliv ery apparatus of approved type, coinprising in theform shown threerotary'fly devices 14,

is mounted a short distance from the" rear f acezofthe guidebars12 Each ofthe guide barslflis provided with diagonally, disposed portion, as indicated. at 15 in Fig. 1, such diagonally disposed portion being sub-j '20 V upon-which thefly devices l lirotate. In the V "stantially intheform-ofan-arc about the axis normaloperation of the apparatus, the papers passing downwardly between the fold- I I 7 ,ing rollers 10*and 11 are received in the pocketsprovided by the arms 16 of the fly device andflareicaus'ed to move downwardlyalong "the faces ofthe guide bars so as to be depositedi'n order .upon a series of belts 17. fl he [fly devices 14' are rotated in: counter-clock Iwise' direction in 1 in timedfrelationflto the movement of the papers'between the roll- .erS O and .11 for effecting this result,'as is well understoodflin the art.

A plurality of the belts .17 provided mounted at their rear ends upon pulleys-or 1 sheaves 18 which are driven slowly fol-carry- Ting'thefupperpliesof,thebelts towardthe le'ftjin s"aid Fig. 1 for causing the papers to i a beV distribud ed;inregularlyspaced-relation upon tlie'belts under normal. conditions l For causing one of the papersat,timedintervals to-assume a changed position upon the beltsl'f as coni'paredfwith the position ofthe remaining papersthereon, I havefprovided a plurality of stop arms lfiwhich are nore mallyi held in position above the diagonally (disposed, porti ons of the guide bars 12, as is indicated in Fig. 1, but whichare movable downwardly beyond the guidebarsinto the pathof the papers at thelde'sired intervals for causing a changed position of one of the paipers. The forwardendsof the arms-19 are notchedso as readily to receive thej lead edge o'flthe paper'in the-angle of the. notch, with the lower finger of the notch in such posi-v tion insubstantial alignment with the as to providea support for the paper from underneath as'well as to'st'op the forward movement of the paper; By the provision of-the angularly arranged fingers forming 'the 7 notch, a paper engaging the notch from-above is'hfeld in p osition'and the leadedge ofi the paper prevented from shifting vin-position 'with'respect to the arm cluring the downward movement of the arm andpaper together for i the deposit of the paper upon the receiver.

'For providing the desired movement of 7 the" stop arms 19, such arms arev slidably mounted in slide boxes 20 which in turn are mountedupona rock shaft 2l.so as,to swing vertically thereabout under. control of the rock shaft.- The. means for controlling the j 7 position of the rock shaft 21 and for controlling thus the angular position of; the slide boxes 20 and itherstop ar'ms 19 comprises an v arm 22- carried by said shaft at one end por- I tion thereof, being provided with a roller 23 which engages a cam 24: mounted upon a drive shaft 25, such. shaft 25 being thegshaft tion shown the shaft 25 being given a singlecomplete rotation for each fifty papers passing between the rollers 10 and 11 to the delivery apparatus.

For controlling the spect to the slideboxes 20, I have provided links 26 pivotally connected at their upper a ends with the stop arms and pivotally con-" nected at their lowerends, withiarins 27 arising from the rock shaft 28which is pivotally, mounted in any suitable bearingsfin the I longitudinal-i p'osition of the slidablyinounted stop'arms19 withre-,

frameof the machine. 1 The position of the rock shaft 28 is controlled by a cam 29 11011 rotatably mounted withrrespect, to the shaft 25, such'cam actingupon the shaft28through the medium of a roller-30" carried byan arm 7 31 mounted upon theshaft 28, such rollerengaging the face of thelcam 29. I

With the parts in fthe'positionas trated in Fig. 1, and with. the fly devices 'l and the shaft25 and its drivenparts rotating in counter-clockwise direction in said Fig.1, the stop armslfil. are held out of thfpathof thepapersj passing along the face oftheguide c bars 12; A very short time thereafter, the part-s willihave assumed the position shown" in Fig. 3, with the roller123 in contact'with.

the step 32 of the cam 24, thestep 32 being located in suchposition asato'jcause' t-he stop I arm 1 9 to standfin positionimmediatelyibelow fthe upper end of the diagonally disposed po tion-15 i the'gu'ide bar 1 insuchp051: tion that th e"downwardly: moving paper whichhas shortly before entered one: ofthe pockets of the fly device engages the notched forward endof'the stop *arm fro'mfaboveso as to beat least partially supported by said' arm. When the paperfreaches its normal engaging position at the angle of the notch in the stop arm, such paper is under the control determined position on the receiver different from thatat which the adjacent preceding along theprescribed path to a"definite pre-' by 1 of the arm so that upon subsequent down-, ward movement of the arm, the paper is led paper wasf deposited on the receiver. In the construction illustrated, such downward movement. of." the: arm with the paper is broughtabout byreason of thepassa'ge of the position shown in Fig. 4, with a paper .being, held in changed position upon the belt. 17 as compared to theposition taken by theynext 'tion as shown in Fig; 5. parts have assumed the position shown in i Fig. 5, the roller 23 controlling the position preceding: papers thereon, the delivery o-f the papers downwardly continues, the following papers being piled on the arms 19 adjacent'to. the guide bars 12;and extending partially over thetop face of'thedisplaced paper so as to weightit down and prevent its movement-with respect to the adjacentpapers.

After one or morepapers have been deposited on top of the displaced paper so as to render further presence of the arms adjacent to the receiver unnecessary, the arms 1 are slowly withdrawn by a movement backwardly underneath the papers piled thereon soas to deposit such accumulatedpapers on thereceiver. Such movement of the arms is effected by the engagement of the roller with a rise of the cam 29 for moving the arm '27 toward the right in said Fig. 4, serving to movethe stop arm 19 gradually from the po sition shown in Fig. 4 to the retracted posi- Shortly after the of the shaft 21 engages the'rise34 of the'c'am 24 causing the'slide boxes 20'and the stop arms19 to be swung about the shaft 21 into the position as shown'in, Fig. 6, which corresponds with theangular position of the boxes and the stop arms as shown in Fig. 1. Shortly thereaftentheroller 30"passes out of engagement with the rise of the cam 29,:per-

mitting a spring 27 as shown in Fig. 1 to swing the arm 27 toward: the left in Fig. 6 again tothe position as shown in Fig. 1, and

causing the stop arms '19 to reassumethe pos-ition as shown in Fig. 1. 1

From the above description, it will-be seen that normally the stop arm stands in the position shown in Fig. 1; that at a predeter- V mined time in the rotation of the cam, 24 the stoparm swings downwardly to the position shown in Fig. 3 where it serves by contact with the forwardedge of: a'paper to stopthe downward movement ofsuch paper; that im:

mediately thereafter the stop armwiththe paper in position in thenotched forward end thereof. swings downwardly into the position shown, in Fig. 4 in advance of thenormal position of the paper onithe belt 17; that after'one or more papers have been deposited subsequently on top of the paper in abnormal position'the stop arm'19-is retracted p N ing downwardly. in timed. relation, the comby longitudinal movement substantially partion until one or more subsequently. de-

the stop arms backwardly along the face allel to the races of thebelts; am after, the c stop arm assumes the position shown inFig. 5, the stop arm and slide'box are swung'upwardly tothe position shown in Fig. 6, after which the stop arm isagain moved forward to the position shown in Fig. 1. I

shown in the- I have found the device stop arm downwardly with the paper serves to control the movement of the paper so as to insurethe positioning of the paper at the; desired point upon the belts 17. The retention of the "stop arms 19 in their advanced-.posi

liv'ered papers are deposited on top of the drawings and abovedescribed very satiS- factory in operation. The movement of the changed position paper serves to insure that the .positionof the papers shall'be changed very little if any at all by the withdrawal of theb'elt. V I o I As is clearly shown in Fig. 1, the opposite sides of the cam 24 are formed similarly.

That is to say, at each side thereof the cam 24 is provided with a step 32, a'still lower step 33 and arise 34. lSuch arrangement is provided for use in case it is desired to divide the papers into unit piles of 25 rather than unit piles of 50. For the normal operation of the device as first above described, a shield- 37 is removed and replaced in an opening. 38

1 05 to hold the shield 35 away from the operative I in the cam, thebolt serving in such position edge'portionof the cam. H I

While I prefer to employ a construction '35 pivotally mountedupon a pin 36 is prosubstantially as shown in my drawings and f as above described, it is to be understood that my invention is not limited to that particular form except so far, as the claims are so limited by the prior art, it being understood that changes nay'well bemade in the construction shown'without departing from the spirit'of my invention. r
