CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,431, dated January 10, 1905.

Application filed June 2, 1903. Serial No, 159,763.

To aZZ whom it may concern:

Be it known that I, PETER A. LAwLEss, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Cigarette-h Iachines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to cigarette-machines of that class by which a continuous wrapperstrip is wrapped around a continuous fillerrod of tobacco and the edges joined together to form a continuous cigarette-rod, which is afterward cut into cigarette lengths.

More particularly, the invention relates to means for forming a pasted seam by which the edges of the wrapper-strip are secured together; and the invention aims to provide means whereby a smooth and secure seam may be formed with a narrow lapping of the edges of the wrapper-strip and with the machine operating at a very high speed.

The invention has been made especially with the idea of its application to machines for forming flattened or elliptical cigarettes, although it may be found useful in connection with machines for forming the usual round cigarettes.

Much difficulty has been experienced heretofore with machines for making oval cigarettes with a narrow pasted seam due to the imperfect formation and the breaking open of the seam when the machine is run at a high speed. To avoid this difliculty, I provide in accordance with the present invention aheated pressing or ironing bar or rib mounted in position to bear against the pasted wrapperseam as the cigarette-rod advances from the wrapping-tube or wrapping device. In connection with such aheated ironing-bar I preferably provide a closed setting channel, through which the cigarette passes after the edges of the wrapper-strip have been folded over the filler-rod and pressed together to form the cigarette-rod.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying the various features thereof, and such description will now be given in connection with the accompanying drawings, showing such a preferred construction.

In said drawings, Figure 1 is a plan view of so much of a continuous-rod-cigarette machine as is concerned with the present invention. Fig. 2 is a side view, partly broken away and on an enlarged scale, looking in the direction of the arrow 2 of Fig. 1. Fig. 3 is a sectional View taken on line 3 of Fig. 2. Fig. 1 is a still further enlarged cross-sectional detail view taken on line A of Fig. 2. Fig. 5 is a detail sectional. view taken on line 5 of Fig. 2. Fig. 6 is an enlarged longitudinal sectional view of a suitable form of burner-tube.

Referring to the drawings, 10 represents a wrappingtube for folding the continuous wrapper-strip about the filler-rod of tobacco to form a continuous cigarette rod. This wrapping-tube may be of any suitable construction; but the particular form of tube shown is that shown in an application filed by me April 20, 1903, Serial No. 153,L83, it being formed by a rod or bar 11, having a longitudinal groove in the upper side and provided with overlying guide-pieces and cover-pieces to turn the two side edges of the wrapperstrip inward to overlap on the filler-rod of tobacco and to press and smooth the cigarette rod thus formed. A'suitable pasting apparatus 12, having a paste-applying disk 13, is provided for applying a line of paste to one edge of the wrapper-strip. This pasted edge of the wrapper-strip is then folded down and pressed against the previously-folded edge of the wrapper-strip, as the wrapper-strip and filler-rod pass beneath a guide 1 1, formed by a grooved cap secured to the bar 10, as shown in Figs. 1 and 2, and which, with the groove of the bar 11, forms a closed channel-way. At its rear end the guide 14: is provided .with a pressure-tongue 15, adjustable, as by means of a screw 16, for bearing with greater or less pressure on the pasted seam as the cigaretterod issues from beneath the guide 1 1. The grooved bar 11 extends beyond the guide 14 and is covered by a removable grooved cappiece 17 to form a setting-channel through which the cigarette-rod passes after leaving the guide 14 and tongue 15. The cap-piece 17 is provided with side grooves 18 to form passage-ways for the edges of the feedingtape 1 by which the wrapper-strip is fed through the wrapping-tube, the edges of the tape being turned outward away from the cigarette-rod as the cigarette-rod passes from the guide 14: to the cap-piece 17. This wrapping-tube is more fully shown and described in my said application, Serial No. 153,483.

After leaving the setting-channel the feeding-tape y turns abouta pulley 20 and thence returns to the guide-roll 21. from which it moves forward again through the wrappingtube. The pulley 20 is located a short distance beyond the rear end of the setting-channel and with its uppermost portion substantially horizontally in line with the.bottom of the groove of the bar 11. The cigarette-rod as it issues from the setting-channel advances with the tape 1 to the pulley 20 and thence passes to suitable cutting and delivering mechanism, as usual in machines of this class.

Mounted to bear against the wrapper-seam as the cigarette-rod advances from the settingchannel is an ironing-rib 25, which in the construction shown projects downward from a bar 26. Any suitable means maybe provided for heating the rib 25; but preferably and as shown the bar 26 carries a tubular hood 27, into which projects the flame from a Bunsenburner tube 28, supported by an arm 29, projecting from the bar 26, the hood 27 being preferably provided with series of air-inlet openings 30. The ironing-rib is preferably mounted so as to bear against the wrapperseam from -a point just beyond the setting channel to a point over the center of the pulley 20; but it will be understood that this position of the ironing device may be changed somewhat without departing from the invention. The bar 26 is carried by an arm 31, pivotally mounted in a bracket 32, so that the ironing device may be readily thrown up and back away from the cigarette-rod, as will be readily understood from Fig. 3, thus permitting the machine to be started and the ironing device to be moved into operating position whenever desired and to be readily removed out of position when this is desirable for any purpose. A suitable stop is provided for limiting the downward movement of the arm 31, and thereby holding the ironing device in position for the proper contact of the rib 25 with the cigarette-seam. An adjustable stop is preferably provided, so that the position of the ironing-rib may be adjusted to cause it to bear with greater or less pressure on the cigarette-rod or to accommodate cigarette-rods of different sizes. For this purpose an adjustable screw-stop 33 is preferably provided on the arm 31 in position to bear against a shoulder 34 on the bracket 32.

By the construction shown the bearing-face of the ironing-rib being of less width than the cigarette-rod proper contact of the ironing device with the pasted wrapper-seam may be secured, and by such contact the seam is quickly dried and the paste set as the cigaretterod issues from the setting-channel. I am thus enabled by my invention to form a cigaretterod with a narrow pasted'seam with the machine running at a very-high rate of speed and at the same time to secure a very perfect and smooth scam, the ironing-rib acting not only to dry the seam, but also to iron and smooth the seam as the cigarette-rod passes beneath it.

It will be understood that the invention is not to be limited to the exact construction or arrangement of parts as shown in the drawings and to which the foregoing description has been mainly confined, but that the invention includes changes and modifications thereof within the claims.

What I claim is 1. The combination with a cigarette-wrapping tube for folding a continuous wrapperstrip about a filler-rod, of a heated seam-ironing device having a bearing-face of a width less than the width of the cigarette-rod for bearing on the wrapper-seam as the cigaretterod advances from the wrapping-tube, substantially as described.

2. The combination with a cigarette-wrapping tube for folding a continuous wrapperstrip about a filler-rod, of an ironing-rib extendinglongitudinally of the cigarette-rod and having a bearing-face of a width less than the width of the cigarette-rod for bearing on the wrapper-seam as the cigarette-rod advances from the wrapping-tube, and means for heating said ironing-rib, substantially as described.

3. The combination with a cigarette-wraping tube for folding a continuous wrapperstrip about a filler-rod, of an adjustable ironing-rib extending longitudinally of the cigarette-rod and having a bearing-face of a width less than the width of the cigarette-rod for bearing on the wrapper-seam as the cigaretterod advances from the wrapping-tube, and means for heating said ironing-rib, substantially as described.

4. The combination with a cigarette-wrapping tube for folding a continuous wrapperstrip about a filler-rod, of an ironing-rib extending longitudinally of the cigarette-rod for bearing on the wrapper-seam as the cigaretterod advances from the wrapping-tube, means for heating said rib, and a pivotal support for said rib and heating device whereby the rib may be moved into and out of operative position.

5. The combination with a cigarette-wrapping tube for folding a continuous wrapperstrip about a filler-rod, of an ironing-rib eX- tending longitudinally of the cigarette-rod for bearing on the wrapper-seam as the cigaretterod advances from the wrapping-tube, means for heating said ironing-rib, a pivotal support for said rib and heating device, and an adjustable stop for said support whereby the rib may be adjusted with relation to the cigarette-rod, substantially as described.

6. The combination With a cigarette-wrapping tube for folding a continuous Wrapperstrip about a filler-rod, of a heated seam-ironing device having a bearing-face for bearing on the Wrapper-seam as the cigarette-rod advances from the Wrapping-tube and formed to press the seam toward the filler beyond its normal position relatively to portions of the Wrapper lying laterally beyond the seam, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of tWo subscribing Witnesses.
