SPECIFICATION forming part of Letters Patent No. 419,833, dated January 21, 1890.

Application led January 12, 1889. Serial No. 296,124. (No model.)

.To all whom it may concern.'

Be it known that I, LUTHER O. OROWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Sealing Attachments for Sheet- Delivery Mechanism, .fully described and represented in the following' specification and the accompanying` drawings, forming a part ofthe same.

It is customary at the present time for the publishers of newspapers and other periodicals to furnish large quanties of such publications to newsdealers and agents upon the condition that such as remain unsold after a certain time may be returned to the publishers to be redeemed by refunding the whole or a part of the'purchase price. This manner of transacting business has afforded an opportunity for the perpetration of fraud upon publishers, which has frequently been taken advantage of by newsdealers and agents.

A large class of persons who purchase daily newspapers and other periodicals do not care to preserve them, and as 'a consequence they are thrown aside as soon as read, which is frequently within a few minutes of the time they are purchased. From this it results that large quantities of papers and periodicals accumulate in railway-cars and other public conveyances, and in hotels, club-rooms, and like places. These papers and periodicals have been frequently collected by newsboys or persons in attendance at such places and returned todealers and agents, who in turn returned them to the publishers, demanding the whole or a part of the purchase price. It is the object of the present invention to prevent such fraud, and I attain this object by providing a mechanism which can be combined with the delivery mechanism of an or dinary printing machine, so as to provide each paper as it is delivered with a seal, which connects Vits free edges in such manner that it must be broken in order to unfold the paper for access to the reading matter inside.

InV the accompanying drawings, Figure 1 is a front elevation of a portion of the delivery mechanism of aweb-printing machine, showing applied thereto the mechanism constituting the present invention. Fig. 2 is a rear elevation of the same parts, partly in section. Fig. 3 is a horizontal section taken on the line 3 of Figs. l, 2, and 4. Fig. 4 is avertical section taken on the line 4 of Fig. 3. Figs. 5 and '6 are enlarged detailed views illustrating the cutting mechanism, which will be hereinafter referred to. Fig. 7 is a view of one of the papers, showing the same provided with the seal. Fig. 8 shows a modified form of seal, which will be referred to.

Referring to said drawings, it is to be understood that the delivery mechanism therein partly illustrated is of an ordinary construction, which is capacitated to operate in connection with a web-printing machine to sever the web into sheets and deliver the same with two folds, one longitudinal and one transverse of the sheet. This delivery mechanism consists of a longitudinal folder A, which, as

Letters Patent, No. 331,280, and operates to impart a longitudinal fold to the printed web as it is delivered from the printing mechanism, and a `pair of cutting and folding cylinders B C and co-operating folding-rolls b, which are equipped substantially as shown in my prior Letters Patent, No. 317,740, and are capacitated to sever the longitudinally-folded web into sheets and impart a transverse fold to said sheets, or to sever the web into sheets, associate the sheets into pairs, and impart a transverse fold to the pair of sheets.

The particular form of delivery mechanism illustrated has been selected merely for the purpose ofl showing one practical application of the present invention; but it is to be understood that the invention is not limited in its application to this particular form of delivery mechanism, but can be applied equally well in connection with other forms of folding or cutting and folding mechanism.

In the form of delivery mechanism shown the web of paper D, after being printed, passes over-the folder A, by which it is folded longitudinally and then enters'the bite of the cutting and folding cylinders B O. If the sheets severed from the web are not to be associated, the leading end of thel web will be taken by one of the sets of pins upon the cylinder B and carried around upon that cylillustrated, is of the form shown in my prior IOO inder until the cylinder has made a half-revolution, at which time the sheet will be severed from the web, and at or about the same time the sheet will be folded transversely between the rolls Z). After passing the rolls b the folded sheet will pass to the bite of the pair of folding-rolls c and be delivered into the control of the tapes d, to be conveyed to the piling mechanism, or it may pass to other folding mechanism to be further folded. If the sheets severed from the web are to be associated in pairs, the leading end of the web will be taken by the pins upon the cylinder C and carried around upon that cylinder until the first sheet is severed from the web. The leading end of the first sheet will then be transferred to the pins upon the cylinder B, so as to be associated with the leading end of the web, and the two sheets thus associated will then be folded together off the cylinder B the same as in the case of a single sheet.

For the purpose of applying a seal to the edge of each sheet, so as to connect the free edges of the paper, as before described, there is provided a folding, cutting, and pasting mechanism by which anarrow ribbon of paper is folded longitudinally and advanced in such position that its two plies embrace the edge of the folded sheet or sheets as it or they are delivered from the rolls b and pass to the rolls c. Before being folded this ribbon of paper is partially severed at suitable intervals to form the seals, and is provided upon the side which, after folding, becomes the inside with suitable lines of paste, by which, when the folded ribbon is pressed against the sides of the folded sheet, it is caused to adhere, and thus connect the free edges of the folded sheet. The mechanism is so organized that as each seal is applied it is nipped by accelerated rolls, which operate to detach it from the ribbon.

The organization thus outlined will now be described in detail. The ribbon of paper E is in the case shown led from a roll supported in convenient position parallel with the rolls c, and after passing around a suitable 'leading-roll 2 passes between a pair of cutting-rolls 3 4, where it is operated upon by cutting-blades 5, carried by the respective rolls in such manner as to be partly, but not wholly, severed at suitable intervals to form the seals of the desired width. The blades 5 are, as will be observed, of serrated form, the teeth of the two blades intermeshing, so as to partly sever the paper on an irregular line. One of the blades is arranged so that its teeth do not project beyond the periphery of its roll, while the other blade is arranged tangential to its roll, so that as the two rolls revolve the teeth of the tangential blade will ent-er between the teethl of the other blade, and thus partly sever the paper, the blades beingso arranged that the severance will not becomplet-e, enough of the paper being left to give sufficient strength to permit the rib? bon to be properly advanced. After passing the rolls 3 4, and being thus partly severed,

the ribbon E passes above a pasting-roll 6,y

angles to its previous direction of travel, and v by which the lines of paste applied by the pasting-rolls 6 are brought upon the upper side of the ribbon. From the turning-bar S the ribbon passes over and through a longitudinal folder H, which is of substantially the form shown in my prior Letters Patent, No. 233,994, and by which the ribbon is folded longitudinally, so as to bring the lines of paste applied by the roll 6 upon the inside of the fold. After being folded longitudinally the ribbon passes downward from the folder H and enters the bite of the rolls c near the ends of said rolls, as indicated in Figs. 3 and 4. The folder H is so positioned with relation to the rolls c that as the sheets severed from the web D pass from the rolls Z9 to the rolls c their edges will pass between the external turners 9 of the folder H, and thus be interposed between the two plies of the folded ribbon as said ribbon also passes through the folder and to the bite of the rolls c, as also indicated in Figs. 3 and 4. vThe folder H and web-turner 8 are preferably formed of a single piece of sheet metal, which is bent to the proper form, as shown in the drawings, to form the external turners 9 of the folder, and also a rearwardly-extendin g plate, over which the ribbon passes in its course to the folder, the rear edge of the plate being oblique and folded over to form the web-turner 8.

For the purpose of advancing the folded ribbon over and through the folder H there are provided a pair of feeding-rolls 10, which project through a recess formed in the back of the folder H in position to nip the folded edge of the ribbon outside the path of the sheets passing from the rolls b to the rolls c. To hold the ribbon well back into the folder H and prevent its folded edge from working out of the bite of the rolls 10, the folder is preferably provided with an internal guideiinger l2, which is supported in any suitable position and extends downward between the external turners 9 and within the fold of the ribbon, terminating just above the bite of the rolls 10. The guide-linger 12 is shown as a thin plate; but in some cases it may be preferable to make it in shape more or less a counterpart of the folder.

The mechanism which has been described is driven as follows: The shaft of the cylinder B is provided with a worm 13, which en gages with a worm-gear 14, mounted upon a vertical shaft having a beveled gear 15, which engages with asimilar gear16,mounted upon a stud and connected to a gear 1'7, which en gages through an intermediate 18 with a pinion 19, fixed upon the shaft of the pasting- IOO IIO

roll 6, the opposite end of which shaft is provided with a gear 20, which communicates through an intermediate 21 with a gear 22, iixed upon the shaft of one of the feedingrolls 10, the gear 22 engaging with a similar gear 23 upon the shaft of the other roll. The gear 2.1 also engages 'with a gear24, fixed upon the shaft of the cutting-roll 4f, which latter gear engages with a gear 25 upon the shaft of the other cutting-roll 3, and also with a gear 26, fixed upon the shaft of the leading-roll 2. The gears which have been described are so proportioned with relation to the surface speed of the cylinder B that the ribbon E will be advanced a distance equal to the widthof one of the seals, which are severed from the ribbon foreach sheet that is folded off the cylinder B and delivered from the rolls b to the rolls c-that is to say, at each half-revolution of the cylinder l5-and the parts are so timed that the advance end of the folded ribbon will arrive at the bite of the rolls c just before the rear end of each folded sheet arrives at the bite of said rolls.

The operation of the mechanism thus far described is as-follows: Assuming the machine to be in operation and adjusted to deliver single sheets, the web D will, after leaving the longitudinal folder A, be operated upon by the cylinders B C and rolls l), as before explained. The ribbon E, led from its roll will pass between the `cutting-rolls 3 4, where it will be partially severed at intervals Y suitable to form the seals, and will then as it passes' the roll G receive suitable lines of paste, after which it will pass overthe turning-bar 8 and over and through the longitudinal folder H, and after passing between the feeding-rolls 10 will enter the bite of the rolls c. The parts are so timed, as before explained, that as the iirst sheet delivered from the rolls b passes between the rolls c and arrives in such position that its rear end is nearly at the bite of the rolls c the leading end of theribbon will arrive at the bite of said rolls c, the edge of the folded sheet being interposed between the two plies of the folded ribbon, as before described, and as indicated in Fig. 4. As soon as the leading end of the ribbon enters the bite of the rolls c it will be nipped by said rolls, and as said rolls are moving at a surface speed much in excess of that of the ribbon the first seal f will be detached from the end of the ribbon as it passes between the rolls c, together with the folded sheet, and will be pressed against the sheet, so that its ends will adhere to the sheet and connect the free edges of the paper, as indicated in Fig. 7, thereby making it impossible to unfold the sheet so as to gain access to its inside matter without breaking the seal, and thus indicating that the paper has been sold. The feeding-rolls 10 are so positioned, as will be observed, that the distance between the bite of said rolls and the bite of the rolls c is somewhat more than the width of one seal, but somewhat less than the width of two seals, so that the second seal will be firmly held by the rolls 10, to permit. the first' one to be detached without danger of detaching more than one at a time, and so the operation will continue to be repeated as each sheet is delivered.

Vhen the sheets are associated in pairs, instead of being delivered singly, the operation will be exactly the same, except that the mechanism for advancing the ribbon for the seals will be timed, so as to operate at halfspeed. For this purpose the pinion 19 upon the shaft of the pasting-roll is provided with a companion pinion 27 of twice the size of the pinion 19, and the two pinions are made movable upon the shaft, being secured thereto `ism for advancing the ribbon is driven, which have been described, are suitable for the purpose; but it is to be understood that such connections may be varied widely without departing from. the invention. In most cases it will be preferable to locate the rolls 3 4 and the roll which carries the ribbon and also the pasting-roll parallel with the rolls b and c, and provide the turning-bar 8, for turning the ribbon, to present it to the longitudinal folder. This, however, is not essential. The turning-bar 8 may be omitted, and in such case the pasting-roll, the rolls 3 4, and the roll which carries the ribbon will be arranged at right angles to the rolls b c.

In many cases it will be desirable to provide the seals with some printed matter or design which will prevent them from being easily counterfeited, and where this is desired it can readily be accomplished by providing the roll 3 between the cutting-blade 5 with printingsurfaces, which will print any suitable Inatter upon the seals, and in such case the printing-surfaces upon the roll 3 will be suitably inked by means of a roll 28, driven from the roll 3 and receiving a supply of ink in any suitable manner, but preferably by carrying an absorbent surface which is saturated with ink.

The paste-roll 6, instead of being cut away at its center so as to apply the paste only to the edges of the ribbon, may be so formed as IOO IIO

to apply the paste to the whole width of the Y ribbon, and it is of course evident that the ribbon may be slit so as to form two ribbons, or that two narrow ribbons equivalent to the two plies of the longitudinally-folded ribbon may be used, and in such case the two halves of the ribbon or the two ribbons will pass to the rolls c, so that the edge of the folded sheet will be interposed between them. In passing between the rolls l0 the edges of the two rib-. bons will be pressed together, so as to be united by the past-e upon them, as shown in Fig. S. It is therefore to be understood that the term ribbon, as herein used, is intended to include both the longitudinally-folded ribbon and the two narrow ribbons, which are equivalent to the two plies of the longitudinally-folded ribbon.

l. The combination, with the rolls c for advancing a folded sheet, of a feeding mechanism arranged to advance a ribbon in position to be folded over the edge of the sheet by the rolls c, and a perforator for partially severing the ribbon at suitable intervals, the rolls c being run at a higher speed than the ribbonfeedingmechanism, whereby the sections of the ribbon are separat-eden the line of partial severance, substantially as described.

2. The combination, with the rolls c foradvancin ga folded sheet, of the rolls 10, arranged toadvance a ribbon parallel with and embracing the edge of the sheet, substantially as described.

3. The combination, with a folding and delivery mechanism, of a longitudinal folder H, arranged to-fold a ribbon and deliver it with its two plies embracing the edge of the folded sheet, substantially as described.

4L. The combination, with a folding-delivery mechanism, of a longitudinal folder H, arranged to fold a ribbon and deliver it with its two plies embracing the edge of the folded sheet, and a pasting mechanism for applying paste to said ribbon, substantially as described.

5. The combination, with a folding-delivery mechanism, of a longitudinal folder H, ar-

longitudinally fold a ribbon and deliver it l with its two plies embracing the edge of the sheet, and a web-turner 8, for turning the ribbon to present it tothe folder, substantiallyas described.

7. The combined longitudinal folder H and web-turner 8, composed of sheet metal bent to form the two external turners 9, and having an oblique rear edge forming the Webturner S, substantially as described.

8. The combination, with the longitudinal folder H, having external turners 9, which direct the two sides of the ribbon toward each other, of the feed-rolls l0, arranged to nip the folded edge of the ribbon, substantially as described.

9. The combination, with the longitudinal folder H, having external turners 9, which direct the two sides of the ribbon toward each other, of the feeding-rolls lO, arranged to nip the folded edge of the ribbon, and the guideiingerlfZ, extending inside the fold of the ribbon and acting to retain the folded edge of the ribbon in the bite of the rolls, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
