Patented Oct. 22, 1929 PATENT OFFICIE PETER F. MURPHY, OF MILWAUKEE, WISCONSIN MACHINE FOR APPLYING PASTERS TO FOLDERSAND THE LIKE Application filed December 26, 1925. Serial No. 77,804.

This invention relates to improvements in sealing machines, and more particularly to sealing machines of the type adapted primari- 1y for applying seals to folders, circulars,

pamphlets, catalogs and the like, although as 1 various and sundry purposes.

One object of the present invention is to provide a machine of the character described which shall include a single means for both cutting a seal or sticker from a strip of sealing material and applying the same to one side of the article to be sealed.

Another object is to provide in a sealing machine means for cutting a seal from a strip of sealing material and applying a portion thereof to one side of a folder, together with means for folding the remaining portion of the seal over the edge of the folder and applying the same to the other side thereof.

Other objects and advantages relates to the control of the machine, the feeding of the 4 articles through the machine, the disposition of the unused portion of the sealing strip, the moistening of the sealing strip and to the various other [cooperating mechanisms-and instrumentalities employed for accomplishing the many improved results hereinafter toward the left in Fig. 1;

Fig. 4 is a plan view, partly in section, some of the parts being broken away;

Figs. 5 and 6 are detail fragmentary views of the clutch for connecting and disconnecting the actuating mechanism for the various parts of the machine to and from the drive shaft therefor Fig. 7 is an enlarged sectional view taken on line 7--7 of Fig. 4:; and

Figs. 8 to 12 are views similar to Fig. 7, showing different positions of the mechanism for cutting the seals from the strip and applying the same to the folders.

Referring more particularly to Fig. 7, the machine in the embodiment illustrated comprises, in general, a table 1, a die 3 supported in spaced relation with respect to the base to permit of the folders passing between the die and said table, as shown, a punch 5 supported for relative movement toward and away from table 1, and a gummed strip of sealing material 6 arranged between the punch and die, the punch being adapted upon a single stroke thereof toward base 1 to cooperate with die 3 to punch or out out a seal 7 from strip 6, as shown in Fig. 8, and to apply a portion thereof to the upper side of the folder, as shown in Fig. 9. and means for folding the remaining portion of the seal over the edge of the folder and applying the same to the other side thereof to thus 'seal the same.

The table 1 may be supported by and secured to the up er ends of side frame members 8 and 9 of any suitable construction. a cross member 10 being arranged transversely of and secured to frame members 8 and 9 o support an electric motor or other suitable means 11 connected by means of gears'lQ and 13 to the common drive shaft 14 for the actuating mechanism hereinafter described for thevarious parts of the machine, shaft 14 being journaled in a bearing 15 which may be cast integrally with side frame member-9.

The construction of die 3 and the actuating mechanism for effecting reciprocating movement of punch 5 toward and away from table 1 will now be described. Die 3 is provided "with a vertical hollow shank 16 which punch 5 loosely fits, the shank being provided with slots 17 at the lowerend thereof through which sealing strip 6 passes and with vertical slots 18 through which the ends of pin19 pass, the pin extending through punch 5 and providing a connection between 7 prising the punch yoke being bifurcated to receive the ends of pin 19, as shown in Figs. 4 and 7. Oscillation of shaft 22 to cause vertical reciprocatory, movement of punch 5.

toward and away from table 1 is effected by means of an arm 24 fixed to shaft 22 and pivotally connected to a connecting rod 25 secured to a collar 26 mounted upon an eccentric 27 fixedto a shaft 28 journaled in the downwardly extending flanges 29 of table 1.

Referring to Figs. 3, 5 and 6, one end of 32 and alug 33. A gear wheel 34 is loosely' shaft 28 is extended beyond frame member 9 and provided with a disc wheel 30 fixed thereto by any suitable means such as a key 31 and provided with a circular rim or flange mounted upon this end of shaft'28 and is provided with-a dog 35 loosely mounted on a pin 36 fixed in the gear 34, dog 35 being arranged to engage lug 33, as shown in Fig. 5, and being urged in a counter-clockwise direction to engage the lug by means ofa spring 37 engaging one end of the dog and bein secured to a pin 38 fixed in gear 34. A hand wheel 39 is fixed to shaft 28 and is arranged as shown in Fig. 3 to hold gear wheel 34 against outward axialmovement with respect to the shaft. Gear wheel 34 meshes with a smaller gear wheel 40 fixed to the end of drive shaft 14. From the foregoing it will be seen that spring 37 holds dog 35 in engagement with lug 33 so that wheel 30 which is fixed to shaft 28 will be connected to gear wheel 34 for rotation therewith, and that upon tripping of dog 35 out of engaging relation with lug 33, shaft 28 will be disconnected from motor 11 since gear wheel 34 is loosely mounted upon shaft 28, as explained above.

' The means for tripping dog 35 out of en gaging relation with lug 33 may comprise a latch 41 extending loosely through a guide 42 formed integrally with upright 23 and provided at its upper end with an opening through which the end 43 of a rod 44 loosely 0 extends, the portion 45 of rod 44 being bent at substantially a right angle with respect thereto, as shown in Fig. 4, and journaled in suitable brackets 46 which may be formed integrally with upright members 23, a ,collar 5 47 and handle 48 being fixed on portion 45 of the rod and arranged against brackets 46,

as shown, to prevent axial shifting of the rod. Upon downward movement of handle 48,end 43 of rod 44 will be raised to lift latch 41 to the position thereof shown in Fig. 5, in which pbsition the'latch is out of operative relation with dog 35 to permit engagement of the latter with lug 33 whereby the actuating mechanism for punch 5 is operatively connected to drive shaft 14;. The

handle 48may be provided with an extended portion 49 arranged to engage the underside of the plate 50 arranged transversely of the machine and secured to the upper ends of uprights 23, the extended portion 49 acting to limit downward movement of handle 48 when latch 41 has been moved to inoperative position. Upon release of handle 48, latch 41 will drop by its own weight to the position shown in Fig. 6, in which position it engages dog 35 and causes rotation thereof in a clockwise direction against the action of spring 37 whereby the dog is moved out of engaging relation with lug 33 as it passes the latter to prevent rotation of wheel 30 with gear wheel 34, gear wheel 34 being rotated in the direetion of the arrows in Figs. 5 and 6. An arm '51 is provided with a hub 52 fixed to portion 45 of rod 44 and extends downwardly below the plane of movement of folder 2, the

lower end'53 of the arm being curved forwardly for engagement by the free edges 4 of the folder as the latter is moved forwardly and inserted between table 1 and die 3, whereby the arm is swung forwardly, as shown in Fig. 7, and portion 45 of rod 44 rotated in a counter-clockwise direction to lift latch 41 out of engaging relation with dog 35 to permit engagement of the latter with lug 33 whereby the actuating mechanism for punch 5 is operatively connected to drive shaft 14. After the seal has been applied to the free edges 4 of folder 2 and the latter moved forwardly from engaging relation with end 53 of arm 51, latch 41 drops by its own weight to engage dog 35 and disconnect the actuating mechanism for punch 5 from drive shaft 14, in which position of the latch arm 51 is in a vertical position. By means of arm 51, therefore, and engagement therewith by the free edges 4 of folder 2 upon insertion of the latter between table 1 and die 3, connection of the actuating mechanism for punch 5 is only effected when a folder is in position between table.1 and die 3, as shown in Fig. 7 the actuating mechanism for the punch being disconnected at all other times from drive shaft 14.

A collar 54 is fixed to a shaft 55 arranged transversely of the machine and having its ends journaled in bosses 56 which may be cast integrally with the downwardly extending flanges 29 of table 1, collar 54 being provided with arms 57 formed integrally therewith and having their free ends 58 extending upwardly and arranged to pass through suitable openings 58 in table 1 in position to be engaged by the free edges 4 of folder 2 when these edges have been moved to a position below the left half of the end of punch 5, as shown in Fig. 7. An arm 59 is provided with a collar 60 also fixed to shaft 55, the free end of arm 59 resting upon a cam 61 fixed to shaft 28. The cam 61 is adapted to oscillate shaft 55 in such manner that the ends 58 of arms 57 extend above base 1 during the latter portion of the upward movement of punch 5 and throughout the downward movement thereof until the punch has applied seal 7 to thearticle, as shown in Fig. 9. At this time, however, the lower side of cam 61 comes into engagement with the free end of arm59, to permit rotation of shaft in a clockwise direction to withdraw the ends 58 of arm 57 below the upper surface of table 1 to permit forward movement of folder 2 in the manner hereinafter explained, the free end of arm 59 being held in engagement with cam 61 by the weight of the arm. Cam 61 is so shaped that the high side thereof does not engage arm 59 to cause movement of ends 58 of arms 57 above table 1 until folder 2 has been moved forward to the right to a'positioirbeyond openings 58 in base 1 through which ends 58 pass, these ends then being moved into position above table 1", as shown in Fig. 7 to act as a stop for the free edges of the next folder whereby the free edges of the latter are positioned in proper operative relation with respect to die 3 and punch 5.

The means for moistening the seal 7 before the left half thereof is applied to the upper free edge of the folder will now be described. An atomizer of any well-known type comprising a liquid reservoir 62. and a nozzle 63 directed upwardly I toward the gummed underside of seal 7 is secured in position, as shown in Fig. 8, the nozzle b ing screwed into' a boss 64 cast integrally with table 1. The air nozzle 65 of the atomizer is connectedby means of a flexible tube 66 and pipe 67 to a chamber 68 communicating with the cylinder 69 through a passage controlled by the valve 70, the valve being provided with a stem 71 extending loosely into a cap 72 screwed into and closing one end of chamber 68. The stem 71 extends through valve 70. and into cylinder 69 for engagement by piston 73. A coil spring 7 4 is arranged upon stem 71 be tween cap 72 and valve to urge the latter upon its seat to close the passage between chamber 68 and cylinder 69. The piston rod 75 is connected by means of a rod 76 to a crank pin 77 fixed to a cam 78 which is keyed or otherwise "fixed to shaft 28 for rotation therewith, the shaft being rotated by means of motor 11- in the direction of the arrow shown in Fig. 1. Crank pin 77 is so ar-' ranged that piston 73 is moved to the left and the air in cylinder 69 compressed during the downward vertical movement ,of punch 5 until the latter engages the gummed strip 6 to punch or cut out seal 7 therefrom, at which time piston 73 engages stem 71 of the valve and opens the latter against the action of spring 7 4 to admit compressed air to air nozzle 65 and thus cause a spray of the liquid in reservoir 62 tobe directed against .the gummed underside of seal 7 as shown Fig.

8, before the left half thereof is applied to the upper free edge 4 of the folder upon further downward movement of punch 5 to the position thereof shown in Fig. 9. During the upward stroke of punch 5, piston 73 com pletes its return stroke to the right, valve 70 closing under the action of spring 74 upon disengagement of the piston from stem 71.

The mechanism for effecting intermittent movement of gummed strip 6 through slots 17 to bring an uncut or unpunched part of the strip in position between die 3 and punch 5 during upward vertical movement of punch 5 and after the lower end thereof has been withdrawn from die 3, will now be described. The gummed strip 6 is wound upon a spool .7 9 to form a roll 80, the spool being loosely mounted on a shaft 81 having a reduced end 82 which fits loosely in the bifurcated upper end of a bracket 83 secured to member 50. The other end of shaft 81 is provided with a threaded portion 84 and a reduced portion 85 extending into a cup-shaped member, or socliet 86 provided with a stub 87' extending loosely through an opening in the upper .end of a bracket 87 also secured to member 50, a nut 88 being threaded upon the end of stub 87' to hold socket 86 in position and to permit rotation thereof. The edge of socket 86 is provided with diametrically arranged notches to receive the ends of'a pin 89 whichpasses through shaft 81 whereby the shaft is fixed to socket 86 for rotation therewith. A sprocket wheel 90 fixed upon or formed integrally with member 86 is connected by means of a chain 91 to a second sprocket wheel 92 fixed to the shaft 93 having its ends journaled in brackets 83 and 87. A shaft 94 is arranged parallel to shaft 93 and has its ends also journaled in brackets 83 and-87, shafts 93 and 94 being provided with rollers 95 fixed thereto and arranged in close engagement with each other. A gear wheel 96 is fixed upon shaft 94 and arranged in mesh with a similar gear wheel 97 fixed upon shaft 93, one end of the latter being extended beyond bracket 83 and having a ratchet wheel 98 fixed thereto. An arm 99. is loosely mounted on the extended end of shaft 93 and carries at its free end a awl 100 arranged to engage with the teeth 0 ratchet wheel 98 upon upwardmovement of a rod 101 pivotally connected at 102 to arm 99 whereby rotation of rollers 95 and shaft 81 is effected. Arm 99 may be held against outward axial movement along shaft 93 in any suitable manner such as by riveting over the extended end of the shaft or passing a cotter pin therethrough. H

The lower end of rod 101 is pivotally connected at 103 to alever 104 pivotally mounted on a, pin 105 fixed in the base of one of the upright frame members 23, lever 104 being ar-..

ranged in engagement with cam 78, as shown :inFig. 1, the cam being adapted to effect upward movement of bar 101 and rotation of ratchet wheel 98 and shafts 93 and 81 in a counter-clockwise direction during upward vertical movement of punch 5 and after the lower end of the latter has been withdrawn from die 3. Referring more particularly to Figs. 2,3 and 7, the end of gummed strip 6 is passed under a roller 106 loosely mounted on a pin 107 fixed to a bracket 108 which may be cast integrally with member 50, over a similar roller 109 and down along the front side of shank 16 and through slots 17, upwardly over the rear edge of member 50 and between rollers 95, and is then secured in any suitable manner to a reel 110 provided with a hub 111 loosely mounted on shaft 81. A

collar 112 is fixed to shaft 81 by means of a pin as shown in Fig. 2, and arranged against hub 111 of reel 110 to prevent axial movement of the latter to the right along shaft 81. The means for connecting reel 110 to shaft 81 for rotation therewith may comprise friction discs 113 and 114 loosely arranged on the shaft, disc 113 being fixed in any suitable manner to hub 111 of the reel for rotation therewith and disc 114 being secured in any suitable manner to a disc 115 also loosely mounted on shaft 81 and provided with a lug 115 which is engaged by a finger 116 cast integrally with a collar 117 threaded upon the threaded portion 84 of theshaft for axial adjustment along the same and held in adjusted position by means of a set screw 118, collar 117 being provided with a recess at oneend thereof to receive a coil spring 119 arranged on shaft 81 between the collar and disc 115, as shown. Upon upward movementof rod 101 to effect rotation of shaft 93 in the direction of the arrow in Fig. 3 during the latter part of the upward-movement of punch 5 and the fir'st part of the downward movement of the latter, the lower roller 95 will \be rotated with shaft 93 and the upper roller 95 will be rotated in the o posite direction with respect to the lower ro ler to pull a portion 5 fof strip 6 through slots 17 inthe direction of thelarrows shown in Figs. 3 and 7, Shaft 81 being rotated in the same direction a shaft 93 by. means of sprocket wheels 90 and 92 and chain 91. Reel 110 is thereby rotated to wind up the cut out portion of strip 6, rolls 95 be-.

V ing rotated by the upward movement of rod 101 an amount just suflicient to pull a portion of strip 6 through slots 17 which is slightly greater in length-than the diameter of punch 5 so that a small amount of the strip will remain between the openings therein caused by punch 5, as shown in Fig. 3. An equal portion of the unpunched strip is unwound from roll 80 as the strip is pulled through slots 17 upon rotation of rollers 95. Shafts 81 and 93 rotate at the same rate since sprocket wheels 90 and 92 are equal in diameter and are provided with the same number of teeth. There will be a difference, however, between the dispunched out strip being wound upon reel 110 and the length of the portion of the stri which is pulled between rollers 95 and whic is always the same, this difference increasing as the punched out strip accumulates upon reel 110. As shaft 81 rotates, therefore, there will be a corresponding slippage between fric tion discs 113 and 114 to compensate for this difference between the portion of strip 6 pulled through rollers 95 and the portion of the strip which would otherwise be wound upon reel 110 and thereby break the strip if this frictionalconnection between shaft 81 and reel 110 were -not provided. The frictional engagement between the adjacent faces of friction discs 113 and 114 may be adjusted by loosening set screw 118 and adjusting collar 117 along shaft 81 to compress spring 119 a greater or less amount. The roll .80 is held in position on shaft 81 by means of a disc 120 provided with a boss 121 fixed to shaft 81 by means of a set screw 122 and a similar disc 123 loosely mounted on the shaft and arranged between the roll and reel 110. When roll has been-consumed, the reduced end 82 of shaft 81 is lifted u wardly out of its bearing in the bifurcated end of bracket 83 and the opposite end of the shaft slipped out of engagement with socket member 86. Set screw 122 is then loosened and discs 120 and 123 and spool 79 removed from the shaft. The roll of the punched out strip is also removed from reel 110. g It will, there fore, be seen that shaft 81 may be readily removed to permit removal of the roll of the punched out strip and the placing in posi tion of a new roll.

The mechanism for folding over the right half of paster 7 and applying the same to the lower free edge 4 of folder 2 and for removing the folder from themachine will now be described. Sprocket chains 124 are arranged upon sprocket wheels 125 fixed to shaft 28 for rotation therewith and sprocket wheels 126 which may be loosely mounted on a shaft 127 arranged transversely of the machine and having its ends supported in the downwardly extending flanges 29 of base 1, the chains being provided with outwardly extending spaced lugs 128 arranged to extend above base 1 and to travel along slots 129 therein. Lugs 128 are so arranged and sprocket wheels 125 and 126 are of such diameter that when the operator places the free edges 4 of a folder against the front sides of lugs 128 and moves the folder forwardly with the lugs until the free edges 4 of the folder engage the u wardly extending ends 58 of arms 57, the a jacent lugs 128 will not engage the front or folded edge of the folder until punch 5 has completed its downward stroke to cut out seal 7 and apply the left half thereof to the upper free edge 4, but will engage the folded edge of the folder ust after punch 5 starts its upward stroke. Folder by means of members 130 loosely mounted on a pin 131 fixed to lugs 132 which may be formed integrally with die 3, the free ends of members'130 extending over opening 129 and being provided with cam portions 131 arranged to deflect the right half of seal 7 downwardly into opening 129, as shown in Fig. 10. Upon continued movement to the right of folder 2 by lugs 128 to the position shown in Fig. 11, the free edges 4 of the folder will swing members 130 upwardly, as shown, so that the right half of seal 7 is folded over upon the lower free edge 4 by. its coaotion with the edge 133 of opening 129, the free edges of the folder having sufficient stiffness so that they are not deflected downwardly into opening 129 by members 130. Upon continued movement of the folder to the right by lugs 128, the free edges of the folder are inserted-between rollers 134 fixed upon shaft 28 and rollers 135 fixedupon a shaft 136 having its ends loosely j ournaled in the free ends of arms 137 pivotaily mounted on pins 138 ,fixed in uprights 23, rollers 135 being urged downwardly into close engagement with rollers 134 by means of coil springs 139 arranged upon rods 140 threaded into lugs 141 cast integrally with uprights 23 and provided with adjusting collars 142, the lower ends of springs 139 fitting over lugs 143- which may be formed integrally with arms 137-. A finger 130 may be loosely mounted on pin 131 between members 130 and extended beyond the free ends of the latter, as shown, to hold the free edges 4 of the folder down upon table '1 and to assist in guiding the folder into position between rollers 134 and 135. Rollers 134 and 135 press the free edges 4 and seal 7 applied thereto closely together whereby the paster is securely attached to the-free edges of the folder to secure the latter together, the rollers then carrying the folder further toward the right until the latter drops in front of a blade 144 at the upper end of an arm 145 fixed to a shaft 146 suitably journaled in frame members 8 and 9. An arm 147 is fixed to shaft 146 and connected by means of a link 148 to an arm 149 east integrally with a collar 150 fixed to shaft 22 and forming in effect a continuation of arm 24 which is also cast integrally with collar 150, as shown in Fig. 1. Arms 1 17 and 149 and-link 148 connecting the same are so arranged as to, cause a forward and return movement of blade 144 during movement of the other parts of the machine to apply a seal to one of the folders,

blade 144 being in-its extreme position to the left, 'as viewed in Fig. 1, when one of the folders drops from engagement with roller 134 and 135, as explained above. Blade 144 is then moved to the right to the position thereof shown in Figs. 1 and 4, to move the folder which has just been operated upon to the front end. of the pile 151. The right end of pile 151 is supported by means of a member 152 arranged across longitudinal tracks 153 and adapted to slide along the latter as the pile of folders 151 increases in dimension during operation of the machine, tracks-153 being secured at their opposite ends to a U- shaped member 154 secured by means of screws 155 to longitudinal members 156 and a suitable cross member 157 having its opposite ends secured to frame members 8 and 9, the longitudinal members 156 being secured to frame members 8 and 9 by means of bolts 156. a

A member 158 is arranged across table 1 at the front end thereof to provide a shelf upon which is placed the pile of folders which are to be run through the machine, the underside of'member 158 being provided with a recess 159 to accommodate lugs 128 with which sprocket chains 124 are provided. A guide member 160 is arranged longitudinally upon base 1 and provided with transverse slots 161 for receiving adjusting bolts 162 threaded into the table. In feeding the folders into the machine in the manner above explained, the operator holds one edge of the folder against guide member 160 and slides the folder along the latter until the free edges 4 thereof engage the front sides of lugs 128, as shown in Fig. 7. The seals will therefore always be applied at the same place upon the free edges I voutwardly extending lug 163 arranged to engage latch 41 after the latter has engaged dog 35 to move the same out of engaging relation with lug 33, as shown in Fig. 6, the latch resting upon flange 32. Uponmovement of folder 2 from engagement with the lower end 53 of arm 51, latch 41 will be permitted to drop by its own weight into position to engage dog 35, the dog beingarrange-d so that it will not be engaged by latch 41 until the folder has passed through rollers 134 and 135, at which time punch 5 will be approximately in the middle of its downward stroke. After disengagement of dog 35 from lug 33, lug 163 will engage latch 41 to prevent further movement of the parts of the machine by their own moment of inertia. The parts of the machine, therefore, always come to rest at the between table land die 3, as shown in Fig. .7.

' A complete operation of the machine will now be outlined, starting with the position thereof shown in Fig. 7. Punch 5 completes its downward stroke, cutting out seal 7 and applying the left half thereof to the upper side of the folder. During this operation of the punch piston 73 engaged stem 71 of valve 70 which resulted in a spray of the liquid in reservoir 62 having been directed against the under gummed side of the seal just previous to the application of the latter to the folder. The low side of cam 61 is now in engagement with arm 59 causing Withdrawal of ends 58 of arms '57 as punch 5 begins its upward stroke, so that the oncoming lugs 128 may engage the forward edge of folder 2 and move the same to the right until the other edge thereof passes between rollers 134 and 135. When the lower end of punch 5 is withdrawn from die 3, the high side of cam 78 will begin to engage lever 104 to effect upward movement of rod 101 and rotation of rollers 95 and shaft 81, as explained above, to pull a portion of strip 6 through slots 17 in the direction of the arrows shown in Fig. 7, the length of this portion of the strip being slightly greater than the diameter of punch 5. It will, therefore, be seen that an uncut portion of the gummed strip 6 is moved into position between die 3 and punch 5 during the latter part of the upward movement of the latter and the first part of the downward movement of the same, and

that the punched or cut out strip is rewound upon reel 110 during operation of the machine and as the strip is unwound from roll 80.- When punch 5 is in the position of its downward stroke shown in Fig. 9, the highest art of cam 78 will be in engagement with ever 104, as shown in Fig. l,-.and rod 101 about to commence its downward movement,

during which movement of the latter pawl 100 rides over the teeth of ratchet wheel 98 and therefore causes no rotation of shaft 93 and rollers 95. It'will thus be seen that the parts are so arranged that there is no movement of strip 6 during movement of punch 5 into and out of die 3. When the folder has been moved to the right out of engagement with the lower end 53 of arm 51, latch 41 drops by its own weight into position to engagedog 35 and thereby disconnect shaft 28 from driveshaft 14 after the folder has dropped into position in front of blade 144. If the operator, however, places a folder in position in front of the lugs 128 which carry the preceding folder through the machine, as explained above,'there will always be a folder in engagement with the lower end 53 of arm 51 whereby latch 41 will alwaysbe held in inoperative position, as

- shown in Fig. 5, and the machine driven continuously by drive shaft 14.

Furthermore, during t e latter part of the upward movement of punch 5 and the first part of the downward movement thereof, the folder will be moved to the right by lugs 128 and the right half of seal 7 deflected downwardly into opening 129 by members 130 and bent over upon the lower free edge 4 of the folder by edge 133 of opening 129, asshown in Fig.11. The free edges of the folder and the pastor applied thereto will then be inserted between rollers 134 and 135 which complete the operation and drop the folder in front of blade 144, as explained above.

From the foregoing it will be seen that an improved machine of the character referred to has been provided in which the various parts thereof and actuating mechanism for these parts are operated from a common drive shaft, and that the machine is provided with a punch which, during a single stroke thereof, cuts out a seal from the gummed strip 6 and applies one-half of this seal to one of the free edges of the folder, other mechanism being provided for folding the remaining half of the seal over upon and applying the same to the other free edge of the folder, and that the improved machine has many advantages over those constructed heretofore as regards simplicity of construction, ease of operation, the rate at which the seals may be applied to the folders or other articles, and the cost of manufacture of the machine. Al-

though the machine shown and described cuts out the seals from a strip of gummed material, it is to be understood that the machine shown and described represents but one embodiment of the invention, and that instead of cutting out or removing only a portion of the gummed strip, the entire strip may be consumed, such as would be the case when a strip of cancelled stamps is substituted for the gummed strip 6 shown, any changes in the' machine which would be necessary for this being obvious to those skilled in the art. It will further be seen that the article or folder is moved along the table of the machine by means of the lugs 128 in a straight path toward, through and beyond the various parts of the machine which remove and apply a portion of the strip '6 to the article.

In the foregoing description, the term folder has been employed in a rather general and more or less arbitrary sense and not as defining any limitations upon the invention. As used, this term is intended to include not only folders of all kinds, but in addition, catalogs, pamphlets, circulars and, in fact, all articles requiring or being subject to sealing in the sense herein employed. It is also desired to point out that the invention in its broader aspects is distinctly not limited to a sealing operation, strictly speaking. For instance, the machine could be employed for applying labels, stamps, stickers, etc. to articles of various kinds and in such use the label, sticker, etc. could be applied to the article at any desired location thereon as distinguished from the particular location of the seal on the folder in the embodiment illustrated in the drawings. In the foregoing, therefore, the term seal has been used in a broader sense and is intended to include stamping, labeling and the application of stickers and the like to articles and goods in general and not as imposing limitations such as might be implied from a strict interpretation of the term.

The various parts of the machine, furthermore, may be timed so as to moisten the strip 6 before, after, or at.substantially the some instant during which the seal is punched out by the member or punch 5, and instead of using a gummed strip and applying water thereto, a plain strip may be used and adhesive material applied thereto at the proper instant. Various other changes, of course, may be made, such as in the size, shape and arrangement of parts, without departing from the spirit of the invention or the scope of the claims.
