forming a part of this specification.

My invention relates to a paper feeding device adapted to feed cards or sheets of paper step by step, and has for its object the production of a very simple device of this kind which will positively feed the paper a predetermined distance during each feeding operation and prevent the paper from creeping or slipping during the intervals between the feeding operations. I

The device is particularly adapted for feeding slitted webs of paper, such, for ample, as gangs of shipping tags, although it will be understood that the invention is not limited to such use.

Figure I is a vertical section of a printing machincprovided with a feeder embodying the features of my invention. is a horizontal section. Fig. III is a. perspective view showing the presser members forseparating the slitted edges of the web of paper or tag strip, the abutments for urerenting retrograde movement of the paper, and a feeder positioned to begin the to the side walls 6. The slide bar 4; is slidably fitted to ribs 7 on the walls 6.

8 designates a crank secured to the power shaft 9. and connected to the slide 4 by a It will be noted that rotary slide 4- to reciprocate under the rollers 2, and at the end of each rearward stroke, the rollers 2 and platen framel are elevated by the cams 3, with the result of forcing the Fig. itv

tag strip D against the type wheels, The

tag strip is fed after each printing opera. tion to position the tags consecutively under the wheels A, B and 0, thereby causing three lines of characters to be printed on each individual tag. This printing mechanism has been shown and briefly described merely to show a machine requiring an accurate step by step feeding device associated with my improved paper teeder; and, as .no invention per se is claimed't'or the printing mechanism I do not deem it necessary to show the inkin devices. or other details, iorming part 01 the printing mechanism.

The feeding mechanism comprises feeder arms 11, adjustably fitted to posts 12 on the reciprocating slide 4, each of said feeder arms having a nose lS-at its upper end.

1-ldesignates presser members for separating the slitted edges of the tag strip so as to position one of said edges directly in front of each feeder when the latter occupies its rearniost position. The feeders are reciprocated a greater distance than a step of the feeding operation, sothat beforedieginning to feed they occupy the positions seen in Fig. 1; some distanceaway from. the separated edges of the tag strip. As the feeders moveforwardly, their noses 13- enter the space between the separated edges of the tag strip so as to overlap portions of said strip, thereby positively maintaining the feeders in engagement with the tag strip during the feeding operation. If the feeders were not provided with the. noses 13, the

edges of the lag strip would spring up-- wardly during the feeding movement and slip over the top faces of the feeders, thereby stopping the feed prematurely. However, the noses 13 positively prevent such slippage and, on the return stroke of the feeders, the noses 13 pass freely from between the slitted edges of the tag strip.

As the device does not include any mechanism for dropping the feeders away from the tag strip during the return or bacluvard moven'ients of the feeders, it will beapparent that the tagswill tend to slip backwardly in the guides f i when the feeder moves rearwardly, this slipping tendency being increased by the presser members 14 which force the tag strip dcwnwardly into. frictional engagement with the feeders. To positively prevent.ret -ograde movement of the tag strip, brackets 16, secured to the side walls 6 are provided with abutments 17 adapted to engage edges of the tag strip, as seen in Fig. III, said edges being depressed by the presser members 14 so as to lie in front of said abuiinents 171 The presser members 1% are preferably springs, or yielding arms, or rigid armssecared to cross bars 18.

I claim i 1. A device for moving a slitted web of paper step by step comprising feeder arms, a nose carried by and extending forwardly from one of said feeder arms and adapted to extend between the slitted edges of the paper so as to positively interlock said feeder arm with the slit'ted web of paper, said feeder arms constituting the sole means for advancing the slitted web of paper step by step, and a prcsser member forscparating the slitted edges of said paper to produce a gap for the reception of said forwardly extending nose. I 2. A device for moving: a slitted web of paper step by step comprdsing a reciprocatmg feeder, a feeder arm carried by said feeder, a nose carried by and extending forirardly from said feeder arm and adapted to extend between the slitted edges of the so as to positively maintainthe feeder arm in engagement with said paper during the feeding operation, and a presser member for pressing an edge of the paper directly into the path of travel of the feeder arm; said reciprocating feeder ronstitnting the sole ,ineans for advancing the slitted web of paper step by step.

3. A device for movi'ng a slitted web of paper step by step comprising a. reciprocating feeder, a feeder arm carried by said feeder, a nose carried by and extending forwardly from said feeder arm and adapted to extend between the siitted paper so as to positively maintain the feeder arm in engagement with said paperduring edges of the ed to abut to prevent retrograde movement i of said paper.

t. A device of the character described comprising a feeder for n'xoving a slitted web of paper step by step. said feeder being adapted to move while frietionailly engaged with said paper during the intervals of time between the feeding operations, an abutment for preventing the paper from following the feeder during the intervals of time between the feeding operations, and a prcsser member for separating the slitted edges of said paper and deflecting one of said edges to a pointdirectly in front of said abutment after each feeding operation.

A device of the character described comprising a feeder for moving a slitted web of paper step by step, means for reciprocating said feeder a greater distance than a step/of the feeding movement, an abutpapcr ment for preventing retrograde movement of said paper, a prcsscr memb'erfor separating'the shtted edges of said paper-so as to ,position one of said edges in front of said abutment and feeder after each feeding operation. and a nose carried by and extending forwardly from said feeder adapted to pass between the separated slitted edges of said paper to overlap a portion of said paper and positively hold said paper in enga'ge ment with the feeder during the feeding operation. v ALBERT.
