ing a part of the same.
This invention relates to an apparatus for applying a line of paste to a web or sheet of paper while the latter is on the run.
The apparatus embodying theinvention may be used in connection with many classes of machines which operate upon a web or sheet of paper; but it is especially adapted for use .in connection with a sheet associating 0r folding mechanism. In the case of a sheet-asso ciating mechanism itA may be used to apply a line of paste to one sheet of cach pair before they are associated, so that when associated the two sheets of the pair will be united. In the case of a sheet-folding mechanism it may be used to apply a line of paste to the sheet or a part of the sheet before it is folded, so that when folded the two parts of the sheet which are brought together by the folding will be united.
As a full understanding of the invention can be best given by a detailed description of a mechanism embodying the same, all further preliminary description will be omitted and a full description of such a mechanism will be given, reference being had to the accompanying drawings, in which- Figure 1 is a plan View of a pasting mechanism embodying the present invention, showing the same applied to or combined with an ordinary form of sheet-folding mechanism, so much of the folding mechanism being shown as is necessary to illustrate the operation of the pasting apparatus. Fig. 2 is a sectional elevation ofthe same, taken on the line x a: of Fig. 1. Fig. 3 is aplan View, upon an enlarged scale, of the pasting apparatus alone. Fig. 4

.at the stops 25.
Referring particularly to Figs. 1 and 2, it is to be understood that the folding mechanism therein partially illustrated is of an ordinary form capacitated to impart two folds to asheet, said folds being at right angles to each other. rll-his mechanism consists of two pairs of fold ing-rolls, 90 91, which are arranged at right angles to each other in the usual manner, and two vibrating folding-blades, 92 9S, which are operated, in the usual manner, to double the sheets into the bite of the rolls. The folding mechanism is provided with the usual tapes, 20 21, and guides 22 for conveying the sheets into-position above the rolls 90, and with the usual tapes, 28, and guides 24 for conveying the folded sheets from the rolls 90 into posi- The folding mechanism is also 'provided with the usual stops, 25 26, for arresting the sheets in position above the foldingrolls; The sheet A is brought forward above the rolls 90 and guides 22 by the tapes 2O 21 in the usual manner until it arrives The blade 92 is then vibrated quickly downward,so as to double thesheet into the bite of the rolls-90, thus folding it longitudinally upon its central line. From the rolls 90 the folded sheet is carried outward above the rolls 91 by the tapes 23 until it arrives at the stops 26, and, as its folded edge arrives at these stops, the blade 93 is vibrated quickly downward, so as to double the sheet into the bite of these rolls, thus giving it a second fold at right angles to the first fold. v Vhen a sheet is folded in this manner, itis frequently desirable- -as, for example, when the sheet is printed for an eight-page paper-that the two halves of the sheet, or what, after it is cut along the line of the first fold, becomes the two sheets of the product, should be united along the line between their printed pages, whichline, when the sheet is folded a second time, is also usually the line of the second fold. The pasting apparatus forming the subject-matter of the present invention is especially adapted to accomplish this result. The pasting mechanism proper consists, broadly speaking, of a singleacting force-pump', which is arranged to draw in a supply of paste upon :its suction-stroke:l and to discharge the same in a fine' stream upon the moving sheet during its reverse stroke, thereby applying a fine line of paste to one-half of the sheet, which, when the ICO ' which extends between the side frames ofthe paste.
machine above the folding-rolls 90. This shaft is provided with arms or brackets 95, which support a paste fountain or vat, 100, in which is arranged a vertical cylinder, 99, the lower end of which extends through the bottom of the vat and forms a nozzle, 9, having a contracted opening, 2. The cylinder 99 is provided with a piston or plunger, 98, having a stem or rod, 27, which extends above the upper end of the cylinder and through an opening in the upper end of a tubular shell, 97, arranged to move up and down upon the cylinder 99. The piston-rod 27 is provided with two adjustable nuts or collars, 8, located some distance apart upon opposite sides of the end ofthe shell 97, as shown in Fig. 5. The cylinder 99 is provided, just below the point reached by the piston upon its downward stroke, with one or more openings, 6, through which the paste is drawn into the cylinder upon the suction-strol e of the piston, and the shell 97 is provided with a corresponding number of openings, 7, which are so arranged that when the shell is at the limit of its downward stroke they will partly or wholl y coincide with the openings 6. The purpose of this will be made clear when the operation of the apparatus is explained. rlhe piston or plunger 98 is provided upon its under side with a slender rod or needle, 13, which is of such length that as the piston nears the limit of its downward stroke it will enter the contracted opening 2 of the nozzle 9. This needle serves not only to cut off the discharge ofthe paste at the end of the downward stroke of the piston` but also to clear the opening 2 in case it should become clogged by any hard lumps in the The shell 97 is provided upon opposite sides with studs 10, which are engaged by arms 28, mounted loosely upon a rock-shaft, 96,which is supported in bearings in the arms 95. rlhe arms 28 are connected together by a web, 29, which also forms a shoulder or abutment, 3,the purpose of which will be presently explained.
rlhe operation of thepasting apparatus thus constructed and organized is as follows: ln describing this operation it will be assumed that the rock-shaft 96 is provided with anysuitable form of connections, (not shown,) by which it is rocked at the proper time and to the proper extent to produce the movements of the several parts, which will now be described. The connections for rocking the shaft 96 will be so timed that,as the sheet A is carried forward above the folding-rolls 90, the shaft 96 will be in the position shown in Figs. 1 to G--that is to say, at the limit of its movement from left to right. It will be observed that when the shaft 96 is in this position the feeler 35 is raised above the path of the sheet A, and also that the arms 28, and with them the shell 97 and piston 98, are at the limit of their upward movement, in which position they are arrested by the extensions 31, which are in contact with the shaft 94. It will also be observed that when the parts are in this position the projection 12 is under the pawl 33,so as to hold thepawl in its raised position. As the leading end of the sheet A passes forward above thejfolding-rolls 90, the shaft 96 will commence to rock from right to left, as indicated by the arrow in Fig. 5. As the shaft is thus rocked the weight of the feeler 35 will cause the sleeve 34 to move with the shaft, so that the pin 5 will remain against the end of the slot 4, as shown in Fig. 6, and thus cause the projection 12 to hold the pawl 33 raised until the feeler 35 has been lowered so that its end rests upon the shcet A, as shown in Fig. 7. As soon as the feeler 35 comesinto contact with the sheet it will be arrested thereby, and thus the sleeve 34 and projection 12 will be arrested, so that the continued movement of the shaft 96 will carry the pawl 33 forward off the projection 12 and allow it to fall in IOO IIO
front of the shoulder 3, as shown in Fig. 8. j
. 4, as also shown in saidiigure.
thereby nearly or quite closing said opening,
so as to cut oif the discharge of paste, and at the same time the openings 6 7 are brought into register, so as to allow the paste-to be expelled from t-he cylinder through these opent ings for the remainder of the downward movement of the piston. After the parts have arrived in the position shown in Fig. 10, the movement of the shaft 96 willl be reversed, as indicated in Figs. 11 and 12, and rocked back to the position shown in Fig. 5. As the shaft 96 is thus moved back to its original position the feeler35 will remain in its lowered position until the pin 5 engages with the lowereud of the slot 4, during which time the pawl 33 Willbe carried np onto the projection 12, as shown in Fig. 12. After the pawl 33 has been thus raised the pin 5 will. cause the sleeve 34 to` move with the shaft 96 during the remainder of its returny movement, so as to raise the feeler 35 back to As the piston 98 is forced 2 the position shown in Figs..5 and in time to.y
permit the next sheet to pass beneath it. As the shaft 96 makes its return movement, as just stated, the spring 30 will raise the arms 28, and, as the arms 28 "are raised, they will iirst raise the shell 97 from the position shown .in Fig. 10 until its upperend comes into contact with the nut 8 upon the upper end of the piston-rod 27,'after which. the continued upward movement of the arms 28 will raise the shell still farther, so as to uncover the open# ings 6, and at the same time raisethe piston 98, and thereby. cause the piston to draw in a supply of paste through the openings 6, and this will continue until -the extensions 31 come into contact with the shaft 94 and arrest the arms 28, as shown in Figs. 5 and 6. In this operation it isof course to 'be'uuderstood that the paste-vat is filled with paste to a height above the openings 6.
In an apparatus of this character it is of course highly important that means should be provided by which the pasting vmechanism proper will be prevented Afrom operating except when a sheet is present beneath it to reejected from the cylinder`99 when no sheet was present to receive it, and the paste would in vsuch case fall upon and smear the foldingrolls and other parts of the machine. This is obviatedby the arm or feeler 35 and projection 12. To, make this clear, let it be supposed that when the shaft 96 is rocked from right toleft, as already described, no sheetis in position beneath the feeler 35. In such Vcase the. feeler 35, instead of being arrested in the position shownin Fig. 7, will continue to move downward and the sleeve 31 will continue to move with the shaft 96 during the Whole of its movement from right to left, as shown in Fig. 13. This being the case, the projection 12 will remain beneath the pawl 3 3, so that the.
pawl will Y be held in its raised position and prevented from engaging with the shoulder 3, and as a consequence the arms 28 and the shell 97 and piston 98 will not be operated and no paste will be ejected from the cylinder 99.
By reference to Figs. 1 to at it will be ob- IOO IIO
served that the ends ofthe arms 28 are forked,
so as to permit the studs .10 to be readily discon- The folding mechanism herein shown formsno part of the present invention, but is shown` merely for the purpose of illustrating one of the many ways in which the pasting apparatus which embodies the invention can be usefull y applied. The pasting apparatus can be used equally well in connection with other forms of folding mechanism-such, for example, as those in which the first fold is-made transi-'erselyinsteadof longitudinally of the sheet, or those which impart only a single told instead of two or more lolds, or those in which the fold or l'olds is or are made by a rotating blade and rolls, or a tncking-blade and nipping-jaws.
The pasting apparatus embodying the present invention may also be used equally well in connection with any ol' the ordinary forms 0l' sheet-associating mechanism to apply a line of paste to certain ol' the sheets, so that when they are associaled they will be united along the paste-line. lt is also to bc remarked that in some cases it may be found desirable to so arrange or locate the pasting apparatus that the lines ol' pasle will he applied to thcweb before it is severed into sheets, the lines of paste being in such ease applied in such positions that when the web is severed into sheets and the sheets associated or folded the sheets or the parts of the sheet will he united at the propci` point or points.
The pasting apparatus herein shown embodies the invention in what I regard as its most complete and desirable form. Changes may, however, bc made in certain parts and certain parts may be omitted without wholly departing from the invention. In some cases it may not be found necessary to provide the apparatus with means l'or preventing the discharge ofthe paste from the cylinder 99 when it happens that a sheet is not present beneath the cylinder to receive the paste. This would be the case when, owing to the organization ofthe machine, it happened that the paste falling from the nozzle 9 would not lodge upon any part ol` the machine where it would do harm. In such case the sleeve 3Jc and its projection 12 and feeler may be omitted, or these parts, and also the pawl 33, extensions 8l, and spring 30, may be omitted, the arms 28 being connected rigidly to the shal't 9G. \Vhen the arms 28 are connected rigidly to the shalt 96, the shalt will ol' course have a less movement than in the case shown. It is also to be understood that the apparatus,instead ol' being supported in the manner shown, maybe supported in any other convenient or suitable manner, and also that, instead ot' two, there may be only one ol' the arms 28. It is also to be remarked that, although the shell 97 forms the best form ol' valve which I have devised for controlling thc openings (i, through which the paste is drawn into the cylinder 99, other' lorms of valve apparatus may bc employed for this purpose without departing, essentially, from theinvention. In some cases the piston or plunger 98 and the shell 97, or other valve apparatus for controlling the admission ol'the paste to the cylinder 99, may be operated independently ot' each other.
ln using some kinds ot' paste the needle 13 may not be necessary, and it may therel'ore in such case bc omitted.
