In the present embodiment of the invention, a suitable framework 1 prov'ded, carrying upper and lower tables and 3, the former supporting the mechanism for directly attaching the strips together to form a band, while the latter supports the operating mechanism therefor. A strip supply magazine is provided for supporting a pile of superposed strips which are to be connected end to end. The magazine comprises an angle plate i, whichis arranged with one of its portions horizontal, and the magazine has guided movement vertically on guide posts which are connected to the table 2 by angle plates 6. Grooved rollers 7 are journaied on the magazine at each guide, and the rollers engage the guides as shown. Two guides and two rollers are provided, and the rollers are at the inner faces of the guides. The, magazine is normally pressed upward depthwise of the pile of strips by a sprin 26, which ope 'ates simultaneously on b th ends of the magazine. The spring is arranged b tween bell cranks 22, which are pivoted at 23 to brackets depending from the table 2. One rock arm, the longer, of each bell crank is connected by a link with the magazine 41-, and the other arms of the bell cranks, the shorter arms, are connected by the spring 26, one of the bell cranks having an extension 9.7, so that the connection between the spring and the arms is on opposite sides of the 'pivotal connection 23 of the bell cranks. The spring acts normally to swing both bell. cranks in a direction to move the magazine upward.

A staff 9 depends from the magazine table at the centre thereof, and passes through a bearing sleeve 10 below the table 2. This sleeve is normally drawn upward by a spring 8, arranged between the sleeve and the table 2, and its ultii'nate upper position is limited by a stop 11 depending from the table. Meclr anism is provided in connection with the sleeve 10 for engagingthe staff to normally hold the magazine from upward movement under influence of spring 26, and the mechanism is released at regular intervals; that is whenever a strip is removed from the magazine, to permit the magazine to move upward. Said mechanism comprises a cam 12. secured to shaft 15, journaled in bearings 13 on sleeve 10, transversely of the staff. Shaft 15 has radial arm 14: which is moved up and down through adjustable link 21, and bell crank 19 pivoted at 20 to a frame bracket. To one end of the bell crank is connected follower 18 which embraces the power actuated shaft 17, and has a friction roller cooperating with a cam 16 on shaft 17. lVhen cam 17 causes arm 14 to rotate downwardly or counter clockwise, cam 12 is rotated to grip staff 9, whereupon both the sleeve and staff move down, as arm 14.- further descends. This movement lowers the strips from the arm and the fingers 75, (Figs. 2 and 11) hereinafter more specifically described. hen arm it moves upwardly, or clockwise, the grip of cam 12 on staff 9 is relieved, permitting spring 26 to move the magazine upwardly, and its upward movement will cease when the pile of strips contacts said arm and fingers 75. A spring 1 is employed to assist clockwise rotation of the arm 14. Thus, once during each complete rotation of shaft 17, the stall 9 is gripped and released by the cam 12. and the magazine thereby caused to descend and rise.

The strips of paper to be attached end to end rest in superposed relation on the magazine. Gauge plates 28 are secured to the "crt-ical portion of the angle plate forming the magazine at the guide posts 5, the gauge plates preventing forward movement of the pile of superposed strips. Movable gauge plates are arranged at the rear of the magazine, the said plates 29, which are of resilient material being secured to the posts 5 at their lower ends. A set screw 30 is threaded through the post near its top into engagement with the gauge plate, and by turning the screw the plate maybe moved toward or from the adjacent fixed plate 28. to establish the position of the pile of superposed strips in the magazine. The screw 30 is held in adjusted position by a lock nut 31. The longitudinal position of the strips is established at the end adjacent to the adhesive applying mechanism by means of a gauge plate The plate, which is of resilient material, is secured at its lower end, to a post 33 extending upwardly from the table 1, and the upper end of the plate is engaged by a set screw 34 threaded through the post, and having a Lock nut as shown. By turning the screw in the proper direction, the upper end of the plate may be movedtoward or from the magazine. The upward movement of the magazine under the influence of the spring 26 is limit-ad by an overhanging arm 35, which is justably connected to an angle plate 36 secured to a superstructure 38 above the table 1, by a screw and slot connection 3'2, This arm 35 entendsacross the strips in the magazine, and is engaged by t 1e topmost strip, to limit the upward movement of the magazine.

The superstructure 38 supports an adhesive supply device, including a trough or pan 39. A roller 40 is journaled in the pan, and dips into the adhesive, and the film of adhesive on the roller 40 is determined by a doctor roll 41 ournaled on the tank adjacent to the roller 40. A dancer or spotter is provided for applving adhesive to the rear endof the topmost strip in the magazine reciprocal movement. This dauber or gluer indicated at 42 is in the form of a plate, having its lower end shaped to apply a line of adhesive transversely to the strip,or a line of spots of adhe sive as may be desired. The dauber is supported by a carriage 43 in laterally spaced t v and the carriage is slidable in a guide 44 which extends transversely of a slide 45, having vertical movement in a guideway 46 supported bythe superstructure 38. The parts are so arranged. that when the slide 45 is in the position of Fig. 2, and the carriage 43 is moved transvers iv of the slide in the guiceway-44, the dauber will'be moved past the roller 40, and will contact with the peripheral surface thereof, to take therefrom a film of adhesive, which is afterwards applied to the topmost strip in the magazine. The slide 45 is moved vertically by means of a cam 47 on the shaft 17 before mentioned.

A follower 48 embraces the shaft at one end,

and the other end i otcd to the slide. The follower has a friction roller engaging the edge of the cam. and the follower and the slide are normally pulled downward by a spring 49 arranged between the slide and the table.

The carriage is moved in the guideway 44, by means of a cam 500a the shaft 17. A follower 51 embraces the shaft, and the upper end of the follower is pivoted to one of the arms of a bell crank 52 pivoted at 53 to the table 1. The other arm of the bell crank is connected to the carriage by an eirpansible and contractible link 54, and the bell crank normally urged in a direction to move the e 43 toward the magazine by a spring a--anged between the table and the bell The operation of the mechanism just described is as follows:

The magazine being provided with strips, and the pan 39 with adhesive, when the shaft 17 is rotated, the carriage 43 will be recipro cated'to cause the dauber to contact with the peripheral surface of the roller 40, and to receive therefrom a film of adhesive, and to move into position abovethe adjacent end of the uppermost of the pile of strips in the magazine. hen the dauber is in this position, the cam 47 operates to depress the slide 45, to cause the dauber to contact with the uppermost strip in the magazine, and to d posit thereon a spot or spots of adhesive. The strip supplied with adhesive, is then advanced a short distance, by mechanism to be later described, exposing the end of a succeeding strip for the application of the adhesive.

Sll

be noticed that the carriage 43 and the slide 45 are detachably held in the respective guideways by means of holding plates having screw connection with the guideways.

For directly attaching successive strips together a joining mechanism is employed. As the successive strips are supplied with adhesive and advanced slightly, each is positioned with its advance end lapped upon the rear end of thepreceding strip, for attachmentthereto to fom a band. end remote from the adhesive applying means, which end for convenience may be described as the advance end, the strips abut against the stop plate 60, depending from a table 61 movable vertically with respect to the magazine. The stop plate has a central vertical groove 62 on the face adjacentto the magazine, which receives a tongue 63 on the upper end of a plate 64 secured to the table 2. "When a strip receives its preliminary advancement, it is automatically displaced longitudinally from those in the magazine, the advance end being lifted above the top of the stop plate 60, so that the said end may be lapped upon the upper face of the table 61. The mechanism for advancing the strip from themagazine into lapping relation with the rear end of the preceding strip is shown more particularly in Figs. 11 to 15 inclusive. The said mechanism comprises a suction head 63 which has suction ports, connected. to a suitable e2;- hausting apparatus indicated at 64 by a hose 65. The piston 640 of the exhausting apparatus, indicated in dotted lines in 15 is connected by a link 141 with one end of a lever 142 pivoted to the table 2 at the opposite end, and connected intermediate its ends with a follower 143 embracing the shaft. 71, and having a friction roller cooperating with a cam 144 secured to the shaft. The head is supported by acarriage 66, in laterally spaced relation, and the carriage is mounted to move horizontally in a guide-- At the are superposed, the pr operating with the edge of the cam, and the follower is connected to a lever 7 3 pivoted to the table 2 at one end, and connected at the other by a link 7% with the slide. The connection between the follmver and the lever is an adjustable connection, as shown in Fig. 11, so that the stroke of the slide may be varied. The topmost strip wien engaged and lifted by the suction head is separated from the other strips by means of separating fingers on the table 61, the said fingers being in the form of spi 's or lugs. Against and underneath these lugs the uppermost strip in the magazine may abut to assist in positioning the u )erniost strip. The suction head moves upnard, and then laterally to the right of Fig. 11, and the same time the table 01 is moved downward, and the end of the strip held b the suction head is thereby advanced relative and superposed on the glued end of the previously attached strip on tabl (L. The superposed ends of the strip are just beneath a presser head 76, and as s on as the s rips head is moved downwardly to press them. ti hvv together on the table. The head ext laterally from a bar 77, which is mounted to move vertically in a guide 78 on the frame, and the lower end of the bar is a follower which embraces ashaft 71 journaled on the table 3, parallel with the shaft 1'? and at the opposite end of the table. The follower has a friction roll which cooperates with a cam 79 on the shaft. the cam moving the presser head downward, and it is moved upward by mechanism to be presently described. The bar 77 sectional, as shown in Fig. 11 and the sections are normally held end to end by means of a spring 80 arranged between the sections. hen the attached ends of the strip have been pressed together, the table 61 moves upward, the table being moved by means of a member or link 81, pivoted at its upper end to a slide 82 connected with the table, nd movable in a guide 83 on the frame, and the lower end of the bar is a fol lower embracing the shaft 71, and having a friction roller cooperating with a cam 84: on the shaft. The roller is held in engagement with the cam by means of a spring 85 arranged between the carriage a1 d the table 2. As the carriage 61 nears the end of its upward movement, a lever 86 which is piv oted to the slide 82 intermediate the ends of the lever, engages at one end a stop 87 on the frame, and at the other a pin 88 on the bar 77, and the presser head is moved upward to release the paper strip as the table is moving in the same direction. The provision of the spring 80 permits the press ing to be applied yieldingly and prevents injury to the parts, in case there should be an obstruction between the presser and the table. The carriage 66 is moved horizontally in the guideway 67, by means of a cam 135 on the shaft 71. A follower 13G embracing the shaft, has a friction roller engaging the edge of the cam, and the upper end of the follower is pivoted to one of the arms of a bell crank 137 pivoted at 138 to a bracket plate 139 extending upwardly from the table The connection between the link 130 and the bell crank is an adjustable connection, as shown in Fig. 15, and the arm of the bell crank remote from the link 136 is connected to the carriage (36 by a T k H0. Thus the suction head has horizontal and vertical movement. From the position of Fig. 11 it is first depressed, and afterwards moved slightly rearwardly, then lifted and moved forwardly.

As the carriage reaches the end of its upward movement, feeding mechanism for the band is actuated, to feed the band, to draw the strip just attached away from the pile of superposed strips, and to position the rear glued end thereof for receiving the succeeding strip.

The feeding mechanism includes a pair of feed rolls 89 and 90, the latter being journaled in the frame. while the former is supported by arms 91 pivoted to the frame as indicated at 92. This mounting permits the roller 89 to move toward and from the roller 90, to grasp and release the band. The rollers 89 and are geared together by gear wheels 93 and 94 on the respective shafts, and the gear wheel 94 is driven by a gear wheel 95 on a shaft 96 journaled in the framework, and driven by a belt 97 from a. shaft to be presently described. The roller 90 is driven continuously, and it continuously drives the roller 89. The roller 89 normally contacts, or substantially so, with the roller 90, so that a strip of paper between the rollers will be fed. Feed control mechanism is provided for lifting the roller 89 slightly, to release the band, and thereby arrest feed of the strip by the feeding mechanism during the joining operation, the roller, however, being lifted only high enough to release the band, and not to disengage the gears 93 and 94. The said mechanism comprises a lever 98, pivoted at 99 to the frame, and having an upstanding arm 100 at the end remote from the suction head, which is provided with a friction roller engaging a head 101 held on the sleeve 89' in which the shaft of the roller is journaled. That end of the lever 98 adjacent to the head 101 is normally stressed by a spring 102 arranged between. the head and the adjacent end of the lever, and the opposite end of the lever is provided with 0. depending feed roll controlling pin 103, adjustably connected with the lever. The lower end of the pin is adapted to engage the strip of paper on the table 61, and to be upheld by the strip of paper. When so held the lever 98 is positioned so that itdoes not interfere with the operation of the rollers 89 and 90. When no paper is on the table the pin may drop across the path of'the strip, the opposite end of the lever thus rising and lifting the roller 89 enough to release the grip on the paper. The table 61 has an opening 104 for receiving the end of the pin when it drops. As soon as the rear end of the attached strip of paper is drawn past the pin 103, the pin drops, and the roller v89 is lifted, to release the grip on the paper, thereby to stop the further feeding of the band. The downward movement of the pin 103 is limited by a stop 105 on the frame, which engages the lever 98. The release takes place, just as the rear end of the strip is passing beneath the presser head 76. Mechanism is provided for braking the movement of the band, so that the rear end thereof will stop at the presser head.

The braking mechanism includes a brake shoe 106 pivoted at 107 to the table 61 and having its free end extending toward the suction head, and resting on the upper face of the paper band onthe table. When the suction head moves toward the table 61, it lifts the brake shoe. The suction head has a cam flange 108 at one end which engages an arm 109 on the brake shoe, to lift the shoe when the head moves toward the feed rollers 89 and 90. The completed band is wound on a reel consisting of a hub 110, and a flange constituted by a disc 111. The reel is secured to a shaft 112 journaled in a substantially U shaped swinging frame 113 pivoted to the end of the table 2, as indicated at 114. At the end remote from the reel the shaft carries a peripherally grooved friction disc 115, which is adapted for engagement with a friction wheel 116 on a shaft 117 journaled on the frame 1, parallel with the shaft 112. The frame 113 is swung down to engage the friction wheels 115 and 116, thereby to drive the reel when desired, by means of a treadle 118 pivoted at 119, to the frame 1, and connected to the swinging frame 113 by means of a link 120. The frame is moved upward by a spring 128 arranged between the swinging frame and the frame of the machine. When it is desired to reel up the band, the treadle is depressed, to connect the wheels 115 and 116. Slack is provided in the band, between the reel and the feed rollers, as indicated at 129 in Fig. 1, in order that the glue may set before the band is wound on the reel. The reel is tensioned by means of a shoe 130 which rests upon the wound band. The shoe is on one end of a lever 131 pivoted to the frame, and the shoe is pressed toward the red by means of a spring 132. The link 120 is extensible and contractible having a turn buckle interposed in its length, and the shaft 117 is driven by a belt 121 from the shaft of a motor indicated at 122 mounted on the table 3.

The shaft of the motor 122 is connected by a second belt 123 with a shaft 124 journaled adjacent to the shaft 71. Thepulley and belt connection 97 before mentioned connects the shaft 96 with the shaft 124. The shaft 124 drives the shaft 71, through gearing indicated at 126, and the shaft 71 drives the shaft 17, being connected thereto by a sprocket chain connection 127. In order to prevent lifting of the strip with the pin 103 or with the presser head in case the pin or head should become covered or partially cov ered with adhesive, a stop 133 is arranged above the table 61, between the pin and the suction head. The stop prevents upward lifting of the band by the head or pin.

The operation of the improved machine is as follows r The magazine is supplied with superposed strips of paper of suitable length, the magazine being moved downward to receive the strips. The cam 12 is first released and the magazine isv depressed, and may, be held in depressed position by means of a catch 134 pivoted to the table 2, and adapted to engage above the magazine, as shown in Fig. 7. The pan i supplied with adhesive, and the machine is ready for operation. When the motor is started, the dauber is moved over the glue roll and then down upon the adjacent end of the uppermost strip in the magazine, .5;

and the said end is spotted with adhesive. Immediately thereafter the suction head engages the opposite end of the topmost strip, and moves upward and to the right with the said end. The first strip fed, may be moved into the grip of the feed rollers 89 and manually, and the said rollers by means of the treadle may be operated to properly position this strip with its rear glued end beneath the presser head. The movement of the suction head upwardly and to the right of Fig. 11 properly positions the forward end of the second strip on the rear end of the advance strip, the table 61 being in lowered position this time, and the brake shoebeing lifted by the suction head. The presser head is immediately depressed, and the ends of the strips are pressed tightly together. The table 61 is now lifted, with the presser head in contact therewith, and as it reaches the end of its upward movement, the presser head is lifted by the lever 86. As the table moves upward, the band of paper on the table lifts the pin 103, the rollers 89 and 90 grasp theband and begin to feed the same. The band is fed until the rear end thereof passes from beneath the pin 103, which immediately drops, lifting the roll 89, and releasing the grasp of the roller on the band. The brake shoe checks the movement of the band, so that the rear end thereof is positioned exactly beneath the presser head, and in position to have superposed thereon the advance end of a succeeding strip. As the band is fed away from the machine by the feed rollers, it falls into a loop 129. \Vhen a sufiicient time has elapsed for the setting of the glue, the treadle 118 is operated to connect the wheels and 116 and a portion of the slack is wound up on the reel. The shoe prevents reverse movement of the reel under the weight of the slack strip.

When the table 61 moves downward, after the joining of the strip the feeding of the band is stopped, by the downward movement of the pin 103. The movement of the lever 98 is just suflicient to stop the feed of the band, the further movement of the lever being arrested by the pin 105. lVhen the end of the advancing strip is superposed on the rear end of the preceding strip the table is in lowered position, far enough below the bottom of the pin 103, so that the strip may move into oining position, without interference from the pin. hen the table moves upward, and at the end of its upward movement the pin is lifted to swing the lever 98, to cause the feed rollers to operate to feed the band. Should there be a failure to at,- vancea strip for any reason, and the table move upward, the lower end of the pin passes into the opening 10a, and the feed is not op erated. A succeeding strip must be in joining position before the band feeding mechanism will be operated.
