Cooperating with tlie' sjaid 'transfer .rollersifl of a suitable gathering-machine are the delivery members I 4 which; ass-aforesaid receive cards .13 and deliver-them to 'eonveyed boxes; y In the pre ferredform; the said 'deli'very members l4 4 can i sist of pairs of elongated extension: belts; 15 and 1'6, ea h con stingmtlqop's mounted over op o sitely dispo sed roll'ers fsb that; leii'g ths ligandit are in parallel adjacent 'relation and--adapted to hold therebetween -a-- sheet s'uch T-he said rollers comprise the coacti-n'g -rollers'I9-;and 20 at the receiving end 121 and 'the caeting rollers 22 and}: at thedischarg. end 24 of the said de livery members I 4'. The-belt-ler'igths' l1 and -IB move from the receiving-end? j -=to the discharge end ,24, at uniform speeds'; the belts' beihgactuated by Imeans jgiis haft 25;011 26- suita-blydriven by any, known, means. v j'ljh said shafts -25 are hown supportedb vertiqa ih new-but known mannerwithin the scope of thisinve'ntion; Disposed below, the extension del-iverybelts-i M isthetable29.,Whichgohtains a'lon gitudinal 's'plit center-line of the conveyor and supported by the table, underlie the trays and prevent them from tilting laterally.

In the preferred arrangement, the longitudinal center-line 40 of the conveyor is disposed outwardly beyond the discharge ends 24 of the delivery members l4, and the inner portion 4| of the base plate 36 underlies the forward part of the said extension delivery belt.

operatively associated with each of the banks of delivery extension belts are the stop plates 42, 43 and 44, these being disposed longitudinally along the conveyor belt, and spaced from the discharge ends 24 of said delivery belts, the pre-, ferred position of these stop plates being outwardly beyond the longitudinal conveyor center line 40, substantially in the region of the outer edges 45 of the upright walls 31 of the trays 35. Each of said stop plates 44 are adjustably attached to a supporting bracket 46 by a connecting member 41 which has a longitudinal slot 48 through which extends the adjusting and fastening screw 49. The bracket 46 contains at the inner end thereof a flange 50 which is attached to the said vertical bar 28. The arrangement is hence such that the stop plates 42, 43 and 44 can be adjusted transversely with respect to the conveyor center-line to a position best suited to receive an ejected card, and to cooperate with the wall 31, all in a manner to be hereinafter set forth.

Attached to the table 29 are a plurality of deflector guides, corresponding in number to the number of banks of extension delivery belts. In the preferred construction illustrated, these deflector guides are in the form of stationary cam members 52 and 53, attached to the table by suitable fastening means such as the angle bars 54. Deflector cam 5| is positioned before the bank A, deflector cam 52 is positioned in the region between banks A and B, and deflector cam 53 is positioned in the region between banks B and C. Deflector cam 5|, in the preferred form illustrated, is located at the inner side of the table, whereas the other two deflector cams are located along the outer side of the table. Each of the deflector cams contains a bar spaced above the base plates 36 of the trays, the bottom edge of the said bars being above the upper edges 55 of the lateral rear walls 38 of the trays, and below the upper edges 56 of the medial upright wall 31 of the trays. Thus, as indicated in Figures 2 and 4, the cam bar 51 has its lower edge 58 abovesaid edge 55 and below said edge 56. Each of the said cam bars are also disposed at an inclination to the centerline of the conveyor, the bars 51 and 59 being shown having substantially the same inclinations, whereas the bar 66 being shown as curved with the rear contacting portion 6| making a relatively slight angle with the conveyor centerline and the forward portion 62 approaching the conveyor at a gradually increasing inclination to provide a gradual pick up, as will more clearly hereinafter appear. The cam bars 59, 69 and 51, respectively, are so positioned as to engage and slidably move boxes on the trays 36 to various predetermined positions, as will also be hereinafter more fully explained.

In the operation of this apparatus, boxes 63 are placed upon trays at stations before the cam 5|, the boxes being of a sufficient length to accommodate, in the particular form illustrated, three stacksof cards l3, the particular form of boxes illustrated containing three partitions. As the conveyor and associated trays 35 move in the direction of arrow D, they will be first engaged by the bar 59 of cam 5|, slidably moving said boxes outwardly to the position illustrated before the delivery belt bank A. The position of boxes 64 at this stage is such that the innermost compartment 65 of each of the boxes is substantially centrally located with respect to the longitudinal center-line 40 of the conveyor (Figure l) At this position cards are delivered to each of the compartments 65, in a manner to be more fully hereinafter described. As the boxes 64 before bank A move to the left, they engage the deflecting bar of the cam 52, to be slidably moved inwardly to the second position where the intermediate compartments 66 are now positioned over the center-line 40, cards being delivered into this compartment by the extension delivery belts. Thereafter, the boxes engage the deflecting bar 51 of cam 59, to be slidably moved inwardly until the outer compartments 61 are over center-line 49, in which position cards are operatively delivered by the extension delivery belts to these outer compartments.

It will be noted that in the outermost position of the boxes, that is, before bank A, the overhang of each of the boxes is such that there may be danger of the boxes being caused to strike corner 68 of the rear wall of each tray, with a resulting turning of the boxes about edge 68 as an axis. To prevent this condition, the rearmost portion 6| of cam 52 is at a very slight inclination to the moving belt, the inclination increasing gradually, as aforesaid. The arrangement is hence such that when the boxes are engaged by cam 52, there will at the beginning be a very slight turning force, the effective force being transverse with respect to the conveyor; and thereafter, when the boxes have already been moved inwardly by the bar 66, there is less danger of a turning effect, and accordingly the inclination is increased.

It is further to be noted, that in each of the positions, the bars 59, 60 and 51, respectively, of the deflecting cams are so positioned that although they clear the rear walls 36 of each of the trays, they nevertheless engage the walls of the boxes which extend thereabove.

By referring to Figure 2, it will be seen that cards 13 are fed by rollers l2 towards the delivery member l4, each card being engaged by the coacting belt portions l1 and I8 and ejected outwardly. Thus, card |3a is ejected until it strikes stop member 44, thereby being deflected and caused to drop downwardly. And inasmuch as stop member 44 is positioned at the outer end of rear upright wall 31, stop 44 and wall 31 cooperate to direct an intercepted card downwardly into the proper compartment.

It will be further noted that the shifting of each of the boxes by the cams occurs only at positions where no card deliveries are made. Thus, cam 5| is positioned before bank A, cam 52 is positioned substantially between banks A and B at which region there are no extension delivery belts, and similarly cam 53 is positioned between banks B and C, where there are no delivery belts. Accordingly, the shifting of the boxes does not in any way interfere with the delivery of cards in their proper positions.

According to the operation above described, it will thus be apparent that any predetermined number of variously arranged cards can be continuously and progressively deposited in a plurality of stacks in boxes that are being conveyed.
