With the foregoing objects and others in view, 20 the invention resides in the combinations, ar rangements, and operations of the parts as liquid distributor being broken away; ‘ identi?ed. Referring now more particularly to Figs. 1 and matter disclosed in my pending application Serial 3 . Fig. 12 is a view similar to Fig. 11 but showing the status ‘of the liquid ‘under high suction from Inv Figs. 1 andl2 of the drawings there is shown a device which is designed and adapted to condi the ?apsfor‘the purpose stated; to prepare tape 15 mal condition; sition‘ with relation to the socket I0‘I, as shown in Fig. 2. The tube I08 may be mounted in ?xed‘ position in any suitable manner with re spect to the magazine I0. Water enters the tube I08 fromthe font I05. When the level of the water in the tube I08 drops, due to the dis 45 tribution of the water, air enters through the vent I09 and allows the out?ow of water from the font. It is'to be understood that the ?ap of each envelope as it is advanced by the pad 91 will be partly raised. l-Ience, as each en 50 velope is advanced the flap will pass in contact with the upper surface of the tube I08 and the adhesive substance on the ?ap will take up or be smeared with water passing out of the holes H0 and the slit III.‘ The flap of the envelope 2 2,136,468 may then be secured to the body of the enve in communication with the interior of the font lope to effectually seal the envelope. The forward movement of the pad 91 is su?icient The tube 3'! is somewhat flat and ovoidal in cross to advance each envelope to a pair of pres sure rollers I20 and |2| respectively, which are mounted for rotation beyond the tube I08. The roller I20 has been broken away to show that the roller | 2| is mounted directly therebeneath. The shafts of the rollers I20 and 10 |2| are supported by suitable bearings carried by spaced standards I23, as shown. The roller | 2| is positively driven by any suitable means, the upper roller I20 being caused to rotate as each envelope is fed between the rollers I20 15 and I2I, the rollers I20 and |2| exerting pres sure on opposite sides of each envelope. The ?ap of the envelope in passing between the roll material so as to be secured or a?ixed for vari ous purposes, such as sealing folders, applying printed addresses on envelopes and folders, and 30 applying postage stamps on mail matter. This form of the invention is useful in conjunction with a machine of the type disclosed in my above identified Water ?ows from the socket A water distributing tube 43 of springy metal 20 has one end portion 44 thereof bent substantially at a right angle to the major portion of the tube. The end portion 44 projects upwardly through In Figs. 3 to 12, inclusive, there is shown a 25 further form of moistener which is designed and adapted to prepare or condition tape or strip pending application. The device shown may be used as an attachment, or be per 35 manently incorporated in a machine of the indi— cated character. Referring now more particularly to Figs. 3, 4 65 made by the character of the gum or adhesive on the flap. The socket 36 has formed integral 36 into the cup 4| through a hole 42 in the cup. of the envelope to secure it and so seal the en 60 level of the slit, due to the curvature of the upper walls of the tube 31, as shown most clearly in 10 Figs. 11 and 12. The tube 31 also has an air vent 40 therein spaced from the font end of the slit 38 and occurring in a position to be just be yond the edge of each envelope flap to insure the proper flow of water according to the demands 15 therewith a cup 4|. velope. 55 The tube 31 has a very narrow longitudinal slit 38 therein to distribute a ?lm of water, and said tube also has a series of fine discharge holes 39 therein at one side of the slit 38 and below the ers | 20 and 1| 2| is forced down in contact with |2| ?nally press the flap down against the body 50 section and is tapered toward its closed end. the moistener tube I06 for a thorough wetting 20 of the adhesive on the flap. The rollers I20 and 40 34 and project laterally with respect thereto. and 5, it will be apparent that there are shown spaced standards 20 and 2|. These standards will be arranged adjacent the discharge end of an envelope magazine of the type referred to hereinabove. A shaft 22 is supported in hori zontal position by lugs 23 on the standards 20 and 2|, respectively. Arms 24 have their lower ends connected with the shaft 22. The arms 24 are thus mounted for swinging or pivotal movement, and embody bearings which receive the opposite ends of the shafts respectively of the pressure sealing rollers 25 and 26. The roll ers 25 and 26 are similar to the rollers I20 and HI hereinbefore referred to. A transmission shaft 2‘Iv is mounted for rotation in suitable bearings 28 secured to the standards 20 and 2|. A latch 29 carried by one of the arms 24 is engageable with one end of the shaft 21 in order to latch the sealing rollers 25 and 26 in position. The shaft 21 has a bevel gear 30 fast thereon which meshes with a drive gear 3| of the sheet folding mechanism. The shaft 21 also has a gear 32 fast thereon which meshes with a gear 33 on one end of the shaft of the roller 26 in order to cause the continuous rotation of the roller 26. The gear 33 meshes with a similar gear on the shaft of the upper roller 25 in order to cause the latter to rotate in a direction opposite to the rotation of the roller 26. The moistening device is employed in con junction with the sealing rollers 25 and 26 and also in conjunction with a tape or strip-feeding 70 means to be hereinafter described. The moist the cup 4|, and its upper extremity is secured in any suitable manner to a head 45 adapted to 25 receive an adjusting screw 46 having a valve member 41 which projects into the end portion 44 and snugly ?ts in the same. The end portion 44 has holes 48 diametrically opposite each other which permit water to ?ow from the cup 4| into 30 the tube 43. The end portion 44 also has a hole 49 therein above one of the holes 48, and an air vent 50 secured in the cup 4| adjacent the end portion 44 has its lower end in communication with the hole 49 and its upper end in communi the screw 46 in order to completely shut off both air and water to the tube 43, or to shut off the air only, or to admit both air and water to the tube 43. The tube 43 has a narrow longitudinal waterdistributing slit 5| therein approximating the slit 38 in the tube 31, as shown in Fig. 5. The tube 43 has a branch distributing tube 52 connected therewith so as to be rigid with the portion 44. The tube 52 is bent in order that the major portion thereof will be spaced from and disposed substantially parallel to the dis tributlng portion of the tube 43. The branch tube 52 has a narrow longitudinal water dis tributing slit 53, the said slit opening laterally and downwardly. The branch tube being in communication with the tube 43 will receive 55 water and air therefrom. ' In order to effectually control the ?ow of water from the font 34 to the tube 31, there is provided an air vent tube 54 which is substantially L-shaped. A portion of the tube extends through the socket 36 and rises into the font 34 through the outlet. The other end 55 of the tube 54 is the air inlet end. Air is admitted periodically to the tube 54 in a manner to be described. In order to catch any over?ow of water when the font ?lled with water is in 05 verted to be engaged in the socket 36, there is provided a drain box 56 secured in ?xed position in any suitable manner to the standards 20 and 2|. A drain pipe 51 connected with the box 56 carries off the over?ow of water from the box 70 ener includes a water font or bottle 34 having a into any suitable receptacle provided for that resilient discharge control means 35 on its lower outlet end. The lower discharge end of the font purpose. 34 is received in a socket 36 formed on one end 76 of a distributing tube 31 so that the'tube will be 35 cation with the atmosphere. This vent 50 ad mits air into the tube 43 when the level of the water in the cup falls below the hole 49. The valve member 41 may be adjusted by operating In order to admit quantities of air at regular intervals into the tube 54, in accordance with the demands for water made on the distributing tube 76 3 2,136,468 31, there is provided means as follows: A block 58 is secured in the box 56'an'd' is bored- and threaded to receive the threaded inlet "end 5510f the tube 51$. An ‘air passage‘59 in‘the block 58 communicates ‘at one end with the bore and at its other end opensto ‘a guideway 6| in which a slide 82 is vertically movable up and down.‘ The slide 62 has an air port 63 which maybe brought into and out of registry with the passage‘59 upon up-and-down movement of ‘the slide 62. The slide 82 has a notch“ 64 therein. ‘A crankshaft 85 is mounted for rocking‘movement'in‘bearings 88 and 61, respectively, on the standard 2| and a ‘standard 68. The shaft 65 has a crank 69. A small bracket ‘16 is pivotally connected with the roller 86 below the same. The roller 86 c0 operates with the roller 26 to move the advance 15 the crank 69 as at ‘H. portion of the tape to the pinch of the rollers 25 A connecting rod "has its lower end adjustably connected with the and 26. . . ‘ l bracket ‘l8 as at 13, and its upper end 14 is . Inorder toicut the tape 19 into separate pieces bent laterally and engaged in‘tlie notch 64in the of predetermined length, there is provided means in the present instance as follows. Cooperative 20 slide 52. An adjustable cam ‘15 is mounted ‘on a shaft on which'the gear 3! is mounted. The cam 15 cooperates with a spool or the ‘like on vvthe end of a crank 16 of the shaft 65. A contractile spring Tl has one end thereof connected with the 25 crank 76 and its opposite end connected with the standard 68. The spring yieldingly retains the crank ‘F6 in cooperative engagement with the cam l5 and causes return movement of the crank shaft 65. In each revolution of the cam 15, the 30 slide 62 will be caused to move down and then up, through the intervention of the shaft 55, bracket 18, and rod 12. This action takes place to correspond with the advance of the envelopes to be sealed in succession. In order to cause the movement of the tube 43 35 into and out of water distributing position, in arcuate guides 90 and 9|, respectively, are se cured to the box 56 adjacent'the roller 26 in ?xed relation thereto. The guide 9l_ has a suit able cutter92 on its upper end, the. same con sisting of a series of ?ne teeth bent laterally in 25 ward or toward the guide 90, as shown most clearly in Fig. 8. The tape passes between. the guides 90 and 9| up to the roller 86; In each down movement of the slide 62, the de?ector 89 pushes the tape into cutting relation to the cut 30 ter 92. At this time the tape is being advanced by the cooperation of the rollers 86 and 26, while the roller 83 is down away from the roller 26 out of cooperative engagement with respect thereto due to the down swing of the crank 69. 35 In other words, the tape will be pressed ?at response to the up-and-down movement of the wise against the cutting teeth. slide 62, the slitted end of the tube 43 is secured to the upper end of the slide, as at T8, or in any against the cutting teeth while the tape is being pulled upwardly causes the teeth to penetrate suitable manner. The slit 5| in the tube 43 ap plies a ?lm of water on the front face of each and cut the tape by reason of the cooperative 40 action of de?ector 89 and rollers 86 and 26. The tape will be cut crosswise to sever a piece of predetermined length, the gum of which will be moistened by the tube 52 and will be drawn along by the rollers 25 and 26 and be pressed into contact with the front face of the envelope envelope as it is fed thereto due to the fact that the distributing end of the tube 53 will be ?exed upwardly and retained momentarily as each en velope is being advanced. It is understood that each envelope will be advanced in part by a feeding mechanism and by the rollers 25 and 26. The envelope is designated E (see Fig. 8). The branch tube 52, by virtue of its slit 53, dis tributes or spreads a ?lm of water on the gummed surface of an endless tape or strip 19, which is advanced and cut in separate pieces of pre determined length by means to be hereinafter described. This tape or strip may contain print ed addresses or other matter to be applied to en velopes and folders; or the tape or strip may consist of postage stamps with the usual trans verse lines of perforations, the stamps to be af ‘ ?xed on the face of envelopes, folders, and other 00 regular intervals is _moved into and out of co operative relation with the roller 26 in response to the rocking movement of thecrank shaft 65. A bracket 84 is ?xed to the drain box 56 adjacent the slide 62 and in line with the rollers 82 and 83. The bracket 84 provides end bearings 85, which support a roller 86 cooperating with the roller 26. A rocker frame 81 is arranged between the end bearings 85 and is supported for lock ing movement by the ends of the shaft of the 10 roller 86. The frame 81 has cars 88 through which the lateral end 14 of the rod 12 extends. The frame 81 has a deflector 89 which parallels mail matter. A roll of tape may be supported by any suitable means, indicated generally at 86, and secured to the base of the standards 20 and ‘fl below the sealing rollers 25 and 26. The roll of tape is supported so as to be unwound freely. The feeding of the tape is accomplished by the means and in the manner presently to be described. A frame 8! is ?xedly secured to the crank 69. The frame 8| supports a guide roller 82 and a larger guide roller 83 is mounted on the arbor of the crank 69 between the ends of the frame. The roller 83 cooperates with the roller 25. The tape 19 passes around the rollers 82 and 83, as shown in Fig. 8, and is positively ad vanced periodically ‘by the cooperation of the roller 83 with the roller 26. The roller 83 at Thetape held and thus be secured or ai‘?xed thereto as the en velope is being sealed. It is to be understood that the cutting of the tape into separate pieces will be in timed accord with the feeding and mois tening of each envelope and the wetting on the front face thereof by the tube 43. In operation, the gum or adhesive on the flap of each envelope will pull a water ?lm from the slit 38, which will start from a point near the vent 48, bending upwardly to cover this vent just beyond reach of the edge of the envelope ?ap. Normally, the ?lm will remain that Way with enough air being admitted to the tube 54 by vir tue of the operation of the slide 62, which air 60 is introduced above the water in the font 34. Should the demand for water ?lm be increased by the character of the gum or adhesive surface, width thereof, etc., then the ?lm covering the vent 48 will be drawn down and additional air 65 will enter the tube 31 to insureproper flow and distribution of the water. The additional holes 39, due to their lower level, allow the ?lm of water to protrude, catch on the envelope ?ap, and so on up to break into the ?lm in the slit 70 38, as indicated in Fig. 11. The tape reaching the tube 52 is stiff enough to move away from the roller 26 and, hence, push es against the water ?lm of the slit 53. When long pieces of tape are to be applied, there may be 75 4 2,136,468 a tendency for the tape to move away from the tube 52; also, the lines of perforations between stamps, in the event that the tape is of this char acter, will cause the tape to lack stiffness. There fore, a de?ector and guide 93 carried by the bracket 84 is employed to insure the proper mois tening of the gum or adhesive substance. Where postage stamps are applied, a rupture at the perforations will be caused by the cutter teeth, 10 which are the same number. to the inch as the stamp perforations. By adjusting the cam 15, the cutting of the tape is controlled so as to give separate pieces of the desired length, or rupture at the lines of perforations in the tape. It is to be understood that the device may be 15 used for applying adhesive substance directly to the materials instead of applying water to ad hesive or gum carried by the material. It is not . necessary to moisten both the gummed surface of the tape and the face of each envelope in the same operation, and one feature may be used without the other. Furthermore, it is to be un derstood that details of construction may be modi ?ed and the parts rearranged to carry out the, results looked for without departing from the invention as expressed in the appended claims. I claim: 1. A device for applying suitable liquid to suit able material fed in a de?nite path, comprising a liquid font having a ?exible liquid distributing tube projecting therefrom, means to ?ex said tube to apply liquid to said material at regular intervals, and means to introduce air into said tube above the liquid therein as the tube is ap 10 plying liquid to said material. 2. A device for applying suitable liquid to suit able material, comprising a liquid font having a springy liquid distributing tube, means to spring said tube to dispose it in a liquid distributing po sition, and means to admit air into said font above the liquid therein as said tube is ?exed. 3. A device comprising a liquid font, having a springy liquid distributing element connected in communication with the interior of said font, and cam operated means connected with one end of said' element to spring the latter into and out of a liquid distributing position. .
