ceive the packets as they pass from the main feeding roll. The specific construction and operation of these moistening `rollers 21 and has been clearly sift forth in the above referred to application, and as they form no part of the present invent-ion, further description of the same is deemed unnecessary. f The roller 22 is connected for operation to the main feeding roll 12 by a chain 23 held taut and out of the path of the packets by an idler 24. A platform 25 bridges the space between the main feeding rollv12 and the spacin roll 19'and the moistening rollers 21 an 22, the plat-form 25 directing the packets between the meistening rollers 21 and 22.

The frame 1() carriesI anL initial feeding roll 26 having a preferably rubber periphery and projecting up through a transverse slot 27 formed in the table 11, at a. point spaced rearwardly from the main feeding The initial feeding roll 26 projects slightly above the upper surface of the table 11, and engages the lower face of the lowermostpacket to impart a forward sliding movement to the same. The initial feeding roll 2G is considerably reduced in size relative to the main feeding roll 12, and receives movement therefrom in a lforward direction by a chain 28 held taut beneath the table 11 by an idler 29. As may be seen from Fig. 1 of the drawing, the initial feeding roll 26 is so geared to the main feeding roll 12 by the chain 28 that the initial feeding roll 26 is revolved continuously at a relatively high rate of speed as compared to the angular velocity of the main feeding roll 12. The initial feeding roll 26 is mounted upon a shaft 30, serving as a tie rod in the frame 10. At one side of the table 1l is a guide 31 preferably fixed upon the frame to hold the packets in superimposed relation upon the table, while an adjustable guide 32 is slidably disposed upon the table Il and preferably has connection with the .shaft or tie rod 30 to hold the guide 32 firmly v, hen adjusted. From this structure it will bc understood that the initial feedin roll 26 has a relatively high angular ve ocity as compared with the. angular velocity of the main feeding roll 12, and that therefore the lowermost packets which bear upon the initial feeding roll 26 are fed quickly and uninterruptcdly to the main feeding roll, for a` purpose which will appear from the hereinafter described operation of the device.

From the foregoing description it will readily be seen that the'operation ofthe ima'- proved device is as follows: A number of packets is disposed upon the table 11 against the guide 31 and in superimposed relation. The packets are. pushed forwardly againstthe guard plate 2O and the adjustable guide 32 iS nl ved into position against the oppotion, engages the site edges of the packets. The main feedin roll l2 is now revolved, which o eration e fecis the turning of the initial feeding roll 26. As the packets rest upon the initial feeding roll 26 the lowermost packet is moved forwardly over the table l1 into eni gagement between the main feeding roll 12 and the spacing roll 19. Should, by accident, two packets pass together onto the main feeding roll, the separating roll 19, revolving in a backward or reverse direcu per face of the upper packet am forces tfie same backwardly toward the initial feeding roll 26. This op 'eration admits of the passage of but one packet at a time to the moistening rollers 2l and 22. When the ackets are piled up upon the bed plate t ey are supported at their middle portions upon the initial feeding roll 26. The initial feeding roll 26 therefore, supports practically the entire weight of the superposed packets, and there is thus a greater frictional Contact between the initial feeding roll 26 and the packets than between the packets and the bed plate 11. The forward movement of the initial feeding roll 26 forces the packets against the guard late 2() and the lowermost packet forwar ly toward the main feeding roll l2, a distance sufficient to displace the middle portion of the lower-most packet from the initial feeding roll 26 to the forward endv hed plate l1. At this time the lowernmst packet has greater frictional Contact with the bed plate 11 than with the initial feed ing roll 26, and, therefore, the initial feeding roll 26 no longer elfects the forward feeding of the lowermost packet. The main feeding roll 12 now engages the forward end of the lowermost packet and draws said packet into the machine the initial feeding roll 26 assistinvf to some extent in supporting the rear'en of the parket. The rear end of the packet,which bears against the initial feeding roll 26, holds the second lowermost packet from direct contact with the initial feeding roll 26, and thereby effects an automatic interruption in the feeding of the packets from the pile. As soon as the lowermost packet passes considerably over the main feeding roll l2 the pile of packets is permitted to drop down upon the initial feeding roll whereby the second lowcrmost packet is given a forward impulse resisted only by the separating roll 19. It is thus seen that to effect the positive and automatically interrupted feeding of the packets from the pile, it is necessary to dispose the initial feeding roll 26 at the middle of the bed plate 11 so that it will engage the middle portions ofthe superposcd packets of the pile.

The packets may be piled indefinitely upon the table 11 between the 0fuidcs 3l and 32 as the improved device feedns the packets I claim as new is:-- l

1. In eombination with a main feed roll, a rerersely rotating sepz'tratiu;r roll arranged above the feed roll7 a guard plate disposed immediately behind the, separating' roll, and a bed plate projt-.eting rearwardly from the top oll the main feed roll adapted to support a pile ol superposed parlt'ets, an initial teed roll extending up through the middle portion ot the bed plate and adapted to .support the middle portion of the pile ot paeltets whereby said initial feed rolt is adapted to move the lowermost paeliet t'ornardly a short distance unt-il the forward end ot said packet engages the main l'eed roth the trieA tion between said parket and the bed plate being' greater than the irietion between the initial t'eed roll and the rear end ol' the packet whereby the partit-t is drawn l'orwardly by the main t'eed toll at a redut-ed rate of speed, the rear end otl the lo\\'eruiost paeket resting against the initial feed roll whereby to prevent. eonlaety ot .waid initial feed roll with the next adjaeent parket.

2. An automatit.l feedingY derive compr-its ing)r a forwardly rotating main l'eed roll, a, reversely rotating` separating roll bearing down upon the feed roll, a bed plate extending baelnvardly from the top of the main feed roll and adapted to support a'pile of euperposed packets, a guard plate rising from the forward end of the bed plate adjaeent said `separatinlbr roll7 and an initial feed roll extending' up through the middle ofthe bed plate and adapted to bear against the middle portion ot' the pile paelt'ets whereby to prevlllit the. pile of paeltets` bearirnar its tull weight/upon the bed plate and having an angular veloeity greater than the angular reloeity ol' the main feed roll whereby to iluifldy and uninterruptedly more the lowermoat paeliet to the main feed roll, a distanee sutlieieut to dispose the middle portion ol' said parket forwardly olI the initial feed roll, the t'rietioual eontaet between the bed plate and the lowest packet when moved forwardly being greater than the trietional eontaet between the initial feed roll and the rear end of theI paelt'et whereby the movement ot said paeltet.l is' reduced to the speed of the main roll and the. initial feed roll is held from eontaet with theI next lowermos't packet..
