' 9 Claims. My invention relates to improvements in carton is to provide improvements to single stitch stitching machines whereby the machine may be set to apply any predetermined number of stitches to a carton at properly spaced intervals, to discharge theV carton from under the stitcher lhead and to stop the stitcher head immediately following the placement of said stitches. A further important object is to provide meanswhereby' tie stitches at the ends of each row of stitches.
can be applied in alignment with thel row and 4also be applied with a stitching machinehaving only one stitching head. A further object isto provide means whereby the machine can be altered with little time and'effort to-change the number oi'- stitches to be applied to a fold or carton.
The inventionconsistsof a stitcher having a stitcher head driven .by a source of continuous power, means for moving the work under the stitcher after each stitch is made and devices for operating the stitcher head to apply a predetermined number of stitches before coming to rest, as will be more fully described in the following specification and shown ix the accompanying drawings, in which- Fig. 1 is a side elevational view of the invention showing the stitch timing cam. v I

Fig. 9 is a detail-showing the stitcher head driven gear and stitcher shaft with the primary drive pulley and gear to the invention.'
Fig. 10 is a detail view ofthe stitch timing cam. In. the drawings like characters of reference indicate corresponding parts in each figure.
`The numeral I indicates a frame vconsisting of vertical supports. 2, connecting longitudinal members 3 and 4 and a work table 5 which overhangs one side as4 shown in Figures 3 and 4. The frame I is formed'around the pedestal 6 of a stitcher generally indicated by the numeral 1.
The object of the invention shown in outline only in Figures 1 and 4, as this may be of any type. At the inner end of the arm 8 a motor I6 is provided which is normally continuously running and which is adapted to drive theA stitcher head 9 through a suitable clutch, not shown, andi a gear Il.' The gear II, obviously continuously rotating with the motor, has its hub I2 freely journalled upon the stitcher head sh'aft I3. A trip rod I4, see Figure 9, connects the clutch to enable the drive to be imparted y10 from the gear II to the stitcher head shaft. The trip rodl is connected by a bell crank I4A anda rod I4B, see Figure 9, to a pedal I5 placed at' the base of the frame I adjacent the operators position. As the trip rod is pressed downwardly the clutch engages by spring action and causes the stitcher head shaft I3 to rotate one complete turn, when the trip I4 and the pedal I5 move upwardly by spring action to disengage the clutch. 'Ifhe stitcher mechanism thus far described is of the existing machine to which the contemplated improvements are attached,
Secured to the hub I2 of the continuously rotating gear .II is a pulley I8 connected by a belt I 9 to a pulley 20. The pulley 20 is secured to a. countershaft 2i which is journalled adjacent one end from an arm 22. The arm 22 is supported above the work table; 5 to enable theV carton stitched to pass under it. The inner end' of the countershaft 2| is ntted with spaced pulleys 23. Between the pulleys 23 and freely journalled upon the shaft is a frame 24 extending towards the stitcher head in the free end of which a shaft 25 having corresponding spaced pulleys 26 is journalled. This shaft 25 is also tted with a feed roll 21. The pulleys 23 and 26 are connected together by V-belts 28, the outer faces of which coact with the feed roll 21 to engage the stitched carton to withdraw it from the machine.' Supportedfrom the frame 24 is a stop 29 whichvis adjusted py any suitable means andis adapted to be engaged by a marginal edge of a box when being put in position under the stitcher head 9.
The feed roll 21 an'd the belts 28 are in contact with the. table when the stitcher head is' at rest and are raised during the stitching process as will be apparent'as the description proceeds.
Supported to the rear ofthe stitcher arm 8 is a rock shaft 32 having a crank 33 at one end anda forked arm 34 at its opposite end. The arm 34 is -connected by links 35 to the frame 24 so that by rocking the shaft 32 through the lever 33 the feed roll 21- may be lowered to contact the carton below it..
Below the table 5 an eccentric shaft 36 is the roller a corresponding movement of the carton takes place until the last depression B6 is above the roller when a short movement of the carton is made and nally as the crown AI rides onto the roller againthe seventh stitch is made, which is obviously closer to the sixth than the sixth is to the fifth. The first and last stitch of the line are referred to in the preamble as tie stitches. When the last stitch is made the cam comes to rest through the instrumentalities previously described. Simultaneous with the stopping of the stitching and spacing mechanism, the feed roll 21 will be dropped towards the table 5, so that the carton now bearing upon a dead roll 19 mounted immediately below the roll 21 will remove the carton from under the stitcher head.
From the above it will be obvious that the tie stitches being placed by `a single immovable stitching head must necessarily be in line with the widely spaced stitches of the row.
