PAPER INSERTING DEVICE FOR CIGARETTE MACHINE PRINTERS Filed on 2, 19 2s ENTOR m w 1" ATTORNEY Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE MAXIMILIAN KLEIN, OF LANSDALE, PENNSYLVANIA, ASSIGNOR TO AMERICAN MACHINE 8c FOUNDRY COMPANY, A CORPORATION OF NEW JERSEY PAPER-INSERTING DEVICE FOR CIGARETTE-MACHINE PRINTERS Applicati'onfiled October 2, 1928.

This invention relates to paper inserting devices for cigarette machine printers, its object being to provide mechanical means for leading the end of a continuous paper strip around the printer drum when the paper has torn apart within or before entering the printer, or when a new strip is started through the printer.

' l/Vhile herein described and illustrated as 10 applied to printing apparatus for continuous rod cigarette machines,the new device may equally well be used for inserting the end of any continuous strip into any other mechanism in which such strip is continuously fed around a drum or other revolving part.

' 'Heretofore, the operation of threading the new end of the paper strip into a cigarette machine printer has been performed manu-' ally and as the strip sometimes breaks many times IH'SUCCGSSIOII before the tenslon on the strip is properly adjusted, this operation has resulted in serious loss oft'ime anddecrease of production. This is especially true in the case of the new duplex cigarette machine having two cigarette rods in a horizontal plane, because the rear rod is not as easily accessible as in a slngle rod machme.

In using a printer provided with the new device, it is not necessary to laboriously thread the new end of the strip between the drum and the associated guide rollers, printihg dies and housing partitions, positioned against or close to the periphery of the drum. The paper is inserted, while the machine is 5 running, by merely placing the new end of the strip obliquely upon the drum so that it will be caught'under a narrow endless belt,

guided by suitable rollers into and out of a groove extendlng aroundthe circumference 40 oft-he drum; The rotation of the drum will Serial No. 309,741.

In the accompanying drawings, which form a part of this specification and in which like characters of reference designate the same or like parts:

Fig. 1 is a plan view of a cigarette machine printer, equipped with the new paper inserting device; and

' Fig. 2 is a side elevation of the device shown in Fig. 1.

In carrying the invention into effect, there is provided in combination with a drum carrying a continuous paper strip passing around the drum, means coacting with the drum to grip the leading end of the paper strip at any time while the drum is in motion and to automatically lead said end about the drum, for the purpose of quickly passing the end of the strip about the drum without the laborious hand manipulation of said strip.

In the best construction, this means will in clude an endless belt traveling around said drum to one side of the normal run of the strip. Preferably, there will also be provided guide mechanism for directing the end of the strip into the range of action of said means, and means cooperating with the drum to lift the end of the strip after the same has passed around the drum to a predetermined point of departure. The means above re ferred to may be widely varied within the scope of the appended claims, since'the construction shown and described is but one of many possible embodiments of the same. The invention should, therefore, not be re stricted to the precise details of the structure disclosed.

Referring to the drawings, the cigarette machine frame 3 carries a shaft 4: driven from mechanism of the cigarette machine. This shaft supports at its outer end, the loosely mounted printing drum 5 and a ratchet 6, fixedly secured to said shaft. The pawl 7 is pivoted to one of the spokes of the drum 5 and is pulled into engagement with the ratchet by a spring 8 fastened to one of the other spokes of the .drum. This pawl and ratchet mechanism permits hand rotation of the drum when the cigarette machine is stopped, thereby permitting inserting of the p'aperstripby hand operation of the drum,

5 about roller 21.."

as well as by power operation thereof. Near the rear side of its peripheral surface, the drum 5 has a circumferential groove 9 (Fig. 1) in which is laid a narrow endless belt or cord 10 running over grooved pulleys 11, 12 and 13. Pulleys 11 12 and 13 are mounted on a frame 3, pulley 11 being adjustable to govern the tension of the belt 10. Above the pulley 13, which leads the belt 10 into the groove 9. are placed a pair of paper guides 14 and 15 arranged to conduct the-end bf the paper strip between the drum and the belt 10, which guides are supported by an angle piece 16 attached to the frame 3.

The paper strip P which hangs down from the reel B after a break between the reel and the pulley 13, as, shown in Fig. 3, or as pulled dut to this position after a break in the printer, is led over a guide roller 17 and is fed at an angle to the plane of revolution to the drum, between the guides 14.- and 15, so as to be gripped at its rear corner between the cord 10 and the drum. The strip will then be automatically led by the motion of the drum around said drum past the printer housing partition 18, the printing dies 19 and guide rollers 20 and 21. The roller 21 is pivoted between the arms of forked lever 22, Whith i fi ed y m unt d; n. sh 23 P- ported for rotation by the frame 3. The inner nd. f th he-f 23 arri fixe thereto arm 2a which is pulled by a spring 25 anchored to the frame 3, thereby urging roller 21 against the paper on the drum. A wiping stripf'26- attached to an arm 2-2 impingeson' the drum from a direction opposite to that in which the drum rotates. This wiping strip is. located just beyond roller 21 which is at thepoint of departure of the strip from. the drum during normal; operation of, the printer. The; end of'the paper strip. as it is carried to this; point by the. drum and'the belt 10 is lifted from the drum by this wiping strip, and thereby pulledout from under the belt 1-0; and

directed away from the China, shown at L in Fig. 2. The raised end of the strip. is then pulled. over the roller 21 into the position P, shown in. dotted lines, so as to lead the paper strip to the tobacco feed and the. other parts o-f-the cigarette. The strip will then have been pulled out from under the belt 10- and will align itself on the. center of the drum 5 over. the. insert 28. of resilient material, which serves as a bed: fo-r'the diesv 19. The run of the belt is then. to one' side of the belt 9 and,

accordingly, the latter does not interfere with the strip during" normal operation. It is noted that'a second wiper strip 27 prevents the ,freeiportion L of the strip from. winding Thus, the. present device provides means for quickly and? conveniently leading the. broken or new-'1 end-of a paper strip about the! me; P l ey; even. t gh. the clea ancesbetwe'en therdrnm andi the associated mechanisms are small. It is also noted that due to the small amount of space occupied by this device and the location of the greater part of the same to one side of the normal run of the paper strip, the paper inserting device cannot interfere with the operation of the machine. At the same time,-the device is in complete readiness to function at any time during the operation of the machine.
