Definitions

  • the casing consisting of a rectangular ticking is made longer and wider than the finished mattress.
  • the process of tucking by means of which the top and bottom surfaces of the mattress are tied together with suitable connections, forms a series of arches or pockets within the ticking which serves to shorten the dimensions of the mattress both laterally and longitudinally.
  • the mattress roll forming machine hereinabove referred to comprises a pair of packing needles which enter the side and top of a mattress adjacent the corners thereof to pack stufling of the mattress into said-corner to form said roll which is imi'nediately secured permanently by a sewing needle operation in conjunction with a shuttle to form a double lock stitch.
  • the machine moves forward at regular intervals on the sides of a mattress supporting table upon which said machine is slidably mounted. After each forward movement the packing needles engage the mattress and form the roll and the needle then penetrates said mattress and forms a stitch and the machine is then advanced or moved forward a predetermined distance to again engage the mattress, leaving two threads extending from the site or the last operation to the needle and shuttle in the new position.
  • the present invention has, then, for its primary object, the provision of means for engaging the mattress during the forward movement of the machine between stitches to prevent movement of the mattress, said means moving rearwardly upon the machine at a rate of speed anddistance equal to the forward movement of the machine, said means being released and moved forward during the stationary period of the machine and operated, after the packing needles have again engaged the mattress and just previously to the sewing operation, to re-engage the mattress or ticking just previously to the completion of the forward movement of said means to form a plait of comparatively small dimensions at each movement, to take up the slack in the edges of the mat tress corresponding to the amount of slack taken up by the tufting process, which plait is then sewed by the sewing needle.
  • Another object of the present invention is to provide means for adjusting the amount of slack taken up.
  • a further object of the invention is toprovide improved means of the character described which shall be directly connected to the roll forming and sewing mechanism of the roll forming machine whereby the operation of holding the mattress against movement, when the machine moves forward on the table, may be synchronous with said roll forming and sewing mechanism in conjunction with which it acts.
  • Fig. 2 is a right hand elevation of Fig. 1 disclosing the manner of engaging the mattress, indicated in dotted lines;
  • Fig. 3. is a left hand elevation of Fig. 1
  • Fig. 5 is an enlarged broken view in elevation of the left hand side of Fig. 4 disclosing the forward position of the mattress en aging means;
  • ig. 6 is an enlarged sectional view taken through a portion of a mattress and disclosing the operation of the device.
  • Fig. 7 is a broken sectional detail taken upon the line 77 of Fig. 5.
  • a rectangular mattress supporting table 1 is provided with a top 2 upon which rests the mattress to be operated upon, said mattress being indicatediin dotted lines in Fig.
  • the top 2 of the table 1 is provided around the edges thereof with a guard or rail 3.
  • the table 1 is also provided at the edges thereof with upper and lower racks 5 and 6 engaged by pinions 7 and 8 respectively connected to a shaft 9 rotatably mounted within the machine 10 provided with castors 11 which ride in tracks 12 to support said machine.
  • a suitable motor 14 is connected by means of a chain 16 toa suitable driving trans mission, indicated in general by the numeral 17, to drive a driving shaft- 23 which in turn operates a grooved cam 24 to which is operatively connected a pair of packing needles 26' and a sewing needle 27.
  • a lever'28 operates a pawl and ratchet mechanism 29.to intermittently rotate the shaft 9 and thereby advance the machine 10 atregular intervals by means of the pinions 7 and 8 in engaging relation with the racks 5 and 6 respectively.
  • the cam 24, at the completion of each forward movement of the machine 10 first operates the packing needles 26 to enter the mattress 4 and form aroll on the edge thereof and while said needles 26 are holding the roll so formed the sewing needle 27 is nextoperated to sew and thereby permanently secure the roll so formed. It is dlll'; ing the period of the engagement of the packing needles 26 and previously to the operation of the sewing needle 27 that one of the importantfeatures of the present invention is operated.
  • a cam 31 having a groove 32 engaging a lug 33 on a frame 34 slidably mounted within the upper portion or head of the machine 10 by means of a plate 35 screwed or otherjacent to the formed roll on the mattress and parallel with the movement of the machine 10, and has rotatably mounted therein a pair of longitudinally disposed and parallel shafts 36 provided at one end with grippers 37, arranged to engage and disengage the formed roll immediately back of the packing needles 26 and sewing needles 27, and meshing toothed segments 38 at the other ends of said shafts 37 one of said gated toothed sector 39 movably mounted upon the lower end of a lever 40 pivotally mounted upon the machine 10 as at 41, and having a roller 42 thereon arranged to be engaged by an adjustable cam block 43 detachably mounted upon the periphery of the cam 31 so that rotation of said cam 31 will cause the groove 32 therein to move the frame 34 and grippers 37 operatively connected thereto backward and forward at regular intervals and synchronous with the operation
  • Rotation of the cam 31 will also cause the adjustable cam block 43 to oscillate the lever 40 and thereby partially rotate the shafts 36 and sectors 38 thereon opposite directions, to open and close the grippers 37.
  • the roller 42 of the lever 40 is normally held against the periphery of the cam 31 by means of a spring 46 having one end secured to the upper end of the lever 40 and the other end thereof to be a plate 47 having a plurality of apertures therein to engage a pin 48 on the machine 10.
  • the upper end of the lever 40 is also provided with asuitable handle 51 by means of which said lever 40 may be operated to open the grippers 37 independently of the movement of the cam 31.
  • the grippers 37 are in engaging relation with the mattress 4 at the completion of the packing and sewing operation and as the machine 10 is moved forward by means of the rotation of the shaft 9 and the p'inions 7 and 8 thereon engaging the racks 5 and 6 respectively, the rotation of the cam 31 causes the groove 32 therein to 'move the frame 34 with the shafts 36, sectors 38 and grippers 37 rearwardly while the machine 10 moves forward, and at the same speed and distance as said forward movement of said machine so that the grippers 37 remain stationary relatively to the mattress thereby preventing the tension of the threads extending from said mattress to the packing and sewing needles from mo ing said mattress with said machine.
  • the grippers 37 thus engage and feed the mattress 3 into the path segments 38 also meshing with an elonof the packing needles while said mablock 43 engages the roller 42 of the lever 40 and actuates the elongated sector 39 to partially rotate the segments 38 and the shafts 36 connected thereto to'open the gripper 37 and thereby disengage the mattress 4, said block 43 operating to retain said grippers 37 in a disengaging relation to the mattress 4 while the groove 32 of the cam 31 returns the frame 34 and grippers 37 forwardly to a normal position.
  • the cam block 43 is timed to release the lever 40 and close the gripper 37 on the mattress 4 just previously tothe completion of said forward movement thereby ac-' tuating said grippers 37 to re-engage the ticking of the mattress 4 and move said ticking toward the packing needles 26,- which have meanwhile penetrated the mattress, to form a plait which is permanently secured in position by the ensuing operation of the sewing needle 27.
  • the space between the ends of the grippers 37 may be adjusted to engage the rolls of difi'erent diameters, where different grades of ticking are used, by loosening the nut 52 and moving the sector 39 to open or close the grippers 37 and then tightening said nut 52 to retain'said sector in such adjusted position.
  • the block 43 is split so that one portion thereof may be moved longitudinally to the other to decrease or increase the length of time during which the grippers may be held open, by means of which novel arrangement the amount of slack to be taken up may be adjusted.
  • the sector 39 is elongated to permit a sliding engagement with the toothed segments 38 and permit their opening'and closing operation at any point along throughout their line of movement.
  • the combination with an intermittently moving mattress roll forming machine of a pair of grippers slidably 111313 113- 1sengage a mattress being operated on by said machine; means actuated'by said machine for operating the grippers to engage said mattress and prevent movement of the same during a forward movement of the machine; to disengage said mattress and move forward a distance equal to theforward movement of said machine; means for closing the grippers previously to the conclusion of the forward movement whereby said grip-- pers may engage and gather the ticking of the mattress to take up the slack therein; and means for adjusting the timing of the closing means whereby the amount of slack taken up may be regulated.
