MACHINE FOR MEASURING AND INDEXING MATTRESS BORDER STRIPS Joel G. Strandberg, St. Paul, Minn., assgnor to Beciiik Products, Inc., St. Paul, Minn, a corporation of Minnesota Application April 9, 1956, Serial No. 576,849

12 Claims. (Cl. 271-25) My invention relates generally to machines utilized in the manufacture of mattresses and more -specilicallyto measuring and indexing machines for use in preparing mattress border strips prior to assembly thereof to a mattress. f

Marginal or border strips for mattresses are generally made with inner and outer fabric walls having a relatively thin layer of padding material therebetween and stitched together. These strips are generally made sutiiciently long to provide material for a multiplicity of mattresses, and are shipped or stored in large rolls thereof. Preparatory to being applied to a mattress a strip of predetermined length is drawn from the roll and pierced at selected portions to receive ventilator grommets and handle mounting devices. Inasmuch 'as mattresses are produced in several sizes requiring border strips of various lengths, care must be exercised in the placement of the various ventilators and handle mounting means so that, when the border strip is sewn to the mattress, the handles and ventilators will be positioned evenly and properly thereon.

My present invention is intended primarily for use as an accessory to combination punch and grommet setting devices of the type disclosed and claimed in the United States Letters Patent No. 2,705,087 issued to Michael Bechik, for the purpose of drawing border strip material through said machine and indexing the same as above indicated.

An important object of my invention is the provision of a mattress border strip measuring device which will automatically draw a predetermined length of border strip from 'a source of supply and with intermittent movements, whereby accurately spaced portions of said Alength may be worked upon during intervals between said movements.

Another object of my invention is the provision of a measuring and indexing device as set forth having means for anchoring one end of a border strip and traveling support means movable in one direction to draw said strip from the source of supply, and in the opposite direction to fold the strip after the same has been measured and worked upon.

A still further object of my invention is the provision of a device of the above type having novel means for controlling the intermittent movement of the border strip drawing or feeding means, which control means includes a plurality of groups of control elements, and of mechanism for quickly yand easily moving a selected group of control elements into and out of operative positions in said device, whereby to vary the increments of movement of the strip drawing means and to vary the overall measured length of the border strip.

Another object of my invention is the provision of a machine as set forth having a track, a pair of border strip supporting devices on said track, and means for driving one supporting device in border strip feeding and return directions at substantially twice the speed of the other supporting device, whereby a length of border strip is supported at longitudinally spaced portions by both devices nited States Patent 2,787,466 Patented Apr. 2, 1957 and caused to be folded thereover upon return movements of said devices.

Still another object of my invention is the provision of a machine as set forth which is relatively simple and inexpensive to produce, which is highly eicient in operation, and which is rugged in construction and durable in use.

The above and still further highly important objects and advantages of my invention will become apparent from the following detailed specification, appended claims and attached drawings.

As above indicated, the device of the instant invention is adapted for use as an accessory to machines for punching holes in mattress border strips and inserting grommets in said Vholes for the purpose of Ventilating the interior of the mattress and for supporting opposite end portions of mattress handles. Such a machine is fully disclosed in the Bechik patent, above identified, yand need not be herein described in detail. The machine is indicated by the reference character A'and is adapted to operate on a border strip, indicated at B, which may be assumed to be taken from a suitable source of supply such `as a relatively large roll thereof, not shown.

In the preferred embodiment of my invention illustrated, the numeral l indicates in its entirety a frame structure including an elongated horizontally disposed bridge 2 comprising a plate-like front wall element 3 and an elongated rear channel-shaped element 4. Upright end frames 5 and 6 support opposite ends of the bridge 2 in upwardly spaced relation to the ground or floor, indicated at X. An elongated supporting rail or track 7 extends longitudinally within the bridge 2, and is supported at its opposite end portions -by suporting arms 8 extending rearwardly therefrom to the inner surface of the channel member 4 Iand bolted or otherwise rigidly secured thereto. Mounted for longitudinal traveling movements on the track 7 is a carriage 9 having upper and lower track engaging flanged rollers 10 and 11 respectively journaled thereto. Bolted or otherwise rigidly secured to the carriage 9 isa bracket.. 12,v which. extends forwardly, b.e1o.w the lower edge of the front plate 3 and upwardly to provide means for mounting a mattress border strip engaging andasupportingpulley. elementt13;. The. pulley. element 13 is journaled on a shaft 14 that extends forwardly from the-upper end ofthebracket` 12. A' second carriage 15 is likewise mounted on the-.rail or track. 7 for longitudinal traveling movementsthereon between-the carriage 9 and the. end. ofv ther track 7 adjacent the. end frame. 5.. The secondcarriage. 15, like the carriage 9, isprovided with trackengaginganged rollers 16 by'means of which the carriage 15. travels on the track .7.. Preferably, the carriage like the carriage 9 is provided with a lower pair of track. engaging rollers notshown.

A1 bellz crank' 56 isfmounted forA swinging1movements: onfastub' shaftl '57` that is mountedv is mounted at one end portion in van end wall 72 of thel bridge 2 above the end frame 5 for rotary and axial sliding movements therein. The opposite end of the shaft 71 is supported for rotary and axial sliding movements in a supporting block or the like 73 that is mounted on the supporting arm 8, see Figs. 3 and 4. Rigidly mounted on the control 'shat 71 are a plurality of abutment elements or the like 74, each having axially projecting stop fingers 75, and defining cam acting bottom surfaces 76. Each abutment element 74 is provided with a key 77 which is adapted to be seated in a selected one of a plurality of circumferentially spaced Kaxially extending lteyways 78 in the control shaft 71. As indicated in Fig. 12, the abutment elements 74 are arranged in circumferentialely spaced groups of axially spaced abutment elements for a purpose which will hereinafter be described. A bevel gear 79 is mounted on the end portion of a shaft 71 for :axial sliding movements with respect thereto but for common rotation therewith adjacent the end wall 72. A cooperating bevel gear S is rigidly secured to the lower end of a vertically disposed shaft 81 journaled in a bearing bracket 82 that is anchored to the wall 72. The shaft 81 extends upwardly through a top wall element S3 of the adjacent end of the bridge structure 2, and terminates in an adjustment wheel or handle 8a by means of which the shaft 71 may be rotated.

A rockshaft 85 extends longitudinally within the bridge 2 and is journaled yat its opposite ends in bearings 86 at opposite ends of the bridge structure. With reference to Figs. 5 and l2, it will be seen that the rockshaft 8S extends freely through an aperture S7 in the carriage 15 and through similar apertures 88 in the anchoring block 32 of the carriage 9. Rigidly secured to the rockshaft 35 between the anchoring blocks 32 in the carriage 9 is a stop dog 89 which extends generally rearwardly from the rockshaft 35 and which is movable about the am's of the rockshaft 35 toward and away from an operat-ive position in registration with selected ones of the abutment elements 74 on the control sha-ft 71. With reference particularly to Fig. 5, it will be seen that the stop dog 09 is yieldingly urged toward its operative position by a coil tension spring 90 secured at its upper end to an anchoring pin 91 extending forwardly from the adjacent end of the stop dog 89, and at its lower end to the bottom portion of the carriage 9. One end of the rockshaft 85 extends outwardly beyond the w-all element 72, and has secured thereto an operating handle 92 by means of which the operator may rock the shaft 85 in a direction to move the stop dog out of registration with a given abutment element 74 against the bias of the spring 90. Predetermined rotary movement of the control shaft 71 by the adjustment wheel or handle 84 will position a selected group of abutment elements 74 in the path of travel of the stop dog 89. The several abutment elements of one group, being axially spaced from those of another group, will stop feeding movements of the carriages 9 and 15 at different longitudinally spaced points than those of another group. With the above described arrangement, border strips having different dimensions between the groups of holes and. grommets therein may be obtained without the necessity of shifting the abutment elements 74 longitudinally on the control shaft 71. When it is desired to so change the dimensions between sets of holes or grommets of a border strip, it is merely necessary that the operator turn the adjustment knob or handle 84' in a direction to brinc the selected group of abutment elements 74 into the path of travel of the stop dog 89. For the purpose of controlling the extreme limits of feeding and return movement of the carriage 9, 1 provide stop collars 93 and 94 adjustably secured on the shaft 71, the former It will be ,noted that, during.

feeding movement of the carriages 9 and 15, the stop dog 89 moves into abutting engagement with the adjacent end of the stop linger 75 of one of the abutment elements 74 lying in the path of travel of the stop dog 89. When this occurs, the control shaft 71 will be moved in a direction -from the left to the right with respect to Fig. 7, causing the shift crank 63 to swing the bell crank 56 in Ia direction to move the :switch operating arm 5S to its neutral position to stop the motor 44. During return movements of the carriage 9, the stop dog 39 will engage the cam acting surfaces 76 of successive abutment elements 74 and be cammed downwardly thereby so that the carriage 9 Will continue its return movement, without moving the central shaft 71, until the stop dog 39 engages the stop collar 94, whereby movement is ythen imparted to the control shaft 71 in a direction to stop the motor 44.

The control mechanism of my invention includes an `actuator comprising -a shifter fork pivotally secured to the relatively shor-t larm 62 of Ithe shifting crank 63, by a pivot pin 96. The shifter -fork 95 is provided with a `stem or shank l9'7 that projects upwardly through an opening 98 in the :top plate or 4Wall element 33, and through an opening 99 in a cover element 100 mounted on the top plate 83. I-t will be noted by reference to Figs. 7 land 8 Ithat the laxes of the pivot pin 96 'and the mount- -ing shaft 64 are at right Iangles to each other, whereby the stem 97 may be moved in an arc about the center of the shaft 64 as lwell as in an arc about the axis of the pivot pin 96. The opening 99 -is formed by a pair of slots 101 and 102 that extend longitudinally with respect to the machine `and which are longitudinally and laterally offset from each other. The adjacent ends of the slots 101 and 102 are connected as indica-ted at 103 to define a -neutral stati-on for the stem 97. Said lstem 97 is movable about -the axis of the pivot pin 96 from an inoperative position at the neutral station .103 selectively to a forward action zone defined by Ithe slot 101 or a reverse action zone defined Iby Ithe slot 102. The actuator stem 97 is shown in Fig. 9 as being positioned at the neutral station 103. When the actuator stern 97 is shifted to the forward action zone in the slot 101, it is movable between .an operative forward position, as shown in Fig. 10, at the end 104 of the slot 101, and an idle position at the end 105 of the slot 101. Likewise, when the actuator stem 97 is shifted from its neutral station 103 to the rever-se action zone defined by the slot 102, the same is movable therein between 1an operative position indicated in Fig. -l1 at the end 106 of the slot 102, and an idle position at thev inner end 107 of the slot 102. It will be noted that, when the `actuator stem 97 is shifted from its neutral position to either of the idle positions in the slots 101 or 102, that such shifting is made independently of the shiftcrank 63 and parts connected therewith. However, movement of the actuator stem 97 in either action zone :between the idle and operative positions thereof, causes the shift crank to be moved in directions to energize the motor 44 for opera-tion in either a forward or return direction. The actuator stem 97 extends upwardly throughia central aperture 103 in -a plate-like actua-tor elemen-t 109 slidably resting on the top wall element 83 lbeneath -t-he cover element 100. The opposite side edges of the 'actuator element 109 are notched to provide laterally spaced surface or edge portions 110 and 111 that are engageable respectively with ful- cram acting pins 112 and 113 projecting `upwardly from laterally spaced portions of the top wall element 33 on opposite sides of the actuator element 1109. A pair of coil tension springs 11d and.115 extend genenaily longitudinally of the machine adjacent opposite Isides of the actuator element M9, each thereof having one end anchored to an opposite end portion of -the plate-like element 109 as indicated at 116 and 1117 respectively. The opposite ends of the springs 11d and 115 are anchored -to suitable anchoring pins 118 and 119.projecting upwardly from the plate-like element 83.

With reference to Figs. 9-11, it will be seenthat, when the actuator element 109. is in its neutral. positiomofFig,

9, the actuator stem. 97 is positioned. at the neutral sta:-

'tion103, and the fulcrum-acting pins. 112. and 1 13each engage a respective surface portion 110 and 111V of the plateflilre actuator element 139. At this time, both of the. springs 114Yaud 115are exertingtheir yieldingbiasagainst the actuator element `109 to urge lthesame towardeng-agement of the surface portions 119. and. 111. with. their respective fulerum-acting pins 112 and 113. \Vithrefer.- ence to Fig. l it will be seen that when-the actuator stem 97 is manually shifted toward the. forward action. zone defined by the slot 101, the surface. portion.4 111. moves laterally out of engagement with its cooperating fulcrum acting pin 113, the spring114 moves into. substantially dead center relationship with respect to-thefu'lcrum -pin 1,12, and the, spring 11S causes the actuator element 169 and stem 97 to be. moved. to their operative position in the forward action zone, the actuator eiement109 swing-y ing about the fulcrum pin112. This movement i'sttrans.-V

ferred to the control-shaft 71 through the shift crank 63,. and to the reversing. switch 5.4. throughthe -bell crank..

56 and link S3, whereby to. energize the. motor andcauser the same to drive the carriages 9 and 15. in-a borderstrip drawing or feeding direction toward the. end frame 6.

The motor continues to operate until/the carriagesr9 and.

-15 reach their position P2 and S2 respectively'ofl-ig. l'. At this point the stop dog S9 engages the adjacent nd of the linger 75 of the. first abutment element 7.4 and causes the control sliaft71 to be. moved.in the same di:-

This movement of the control.

reetion as thc carriage. shaft 71 causes the shift cranlc to swing: in.a.direction to move the `actuator stem 97 and the. actuator clement- 15? to the end MES of the slot101 wherein. the.. actuator element is in 4its forward idle position. cated this movement ofthe actuator stem 97. and actuator. element 199 `to their idle position inthe forward. action zone also causes the reversingswitch-54 tobe positioned at neutral thus shutting off the motor 44. Assumingthat. a border strip B has beenat-tached to the clamp 19in the manner above described and the machineA has performed a hole punching and grommet inserting operation on the border strip B ywhile the. carriage 9'V and 15.. are stationed at 4P1 and S1 of Fig. l, the border strip. is nowin a position to be againoperated uponby the machine. A. After the second group of holesthave beentpunchedl and grommets installed in the. border. stripB the oper.-

ator manipulates the handle 92- to rock the shaft 8Sv in. a direction to lswing the stopdog89 out. ofengagement with the adjacent abutment element 74. The spring 115 then moves the actuator stem 97 and actuator. clement 11155 to their operative position of Fig. l0, and swings the shift ycrank in direction to cause the motor. 44. to be reenergized and to move the. control. shaft 71.in the direction of the end frame 5... Reenergization ofthe motor 44 causes the carriages 9 and 10 to advance to their. respective positions P3-and S3.,.whereupon.the. stop dog 87 engages a subsequent abutment element 74 to, cause deenergization of the motor 44 and repositioning of the.l

actuator stem 97 and actuator element 109. at.the. idle position in the forward action zone. At. this point the machine A is again operated after which the handle. 92 is manipulated to cause the border strip B to be drawn or `fed by the carriage 9 un-tiLtbe carriages .9 andlSreach their positions Pdand S4 of Pig. 1. The border. strip B.

is again operated on by the machine A andthe. carriages.

and 15 caused to be moved to their extreme positions P5 and S5 of Fig. l, at whichtimethe stop dog 89 en.- gages the stop colla-r 93. The step` collar 93 is. of a size to prevent the stop dog @from being moved-.down-y wardly out of engagement therewith, and positively. limits further `feeding movement of the carriages9' and i152 At this point the operator manually shifts the actuator stem 97 and actuator element 1.09 from their idle posi tions in the `forward action zone, `tothe` reverse, action zone defined by the slot 102. This movement causes the As above. indifspring.115to;be moved. intosubstantially dead center re lationshipwithy the ifiulcrumpinf1-13 and causessthe spring v114to becomevoperativc to move the actuator stem- 97 andactuator. element 109toward'their operative positions inthe reverse action zone; `It will be noted-that shifting the actuator stem 97 from the slot 1&1V tothe slot 102 causes the. actuator element 169y to be disengaged from the Ifulcr-um pin 112nand the-surface position 111 thereof to operatively. engage the fulcrum pin 113. This movement of the actuator stemandactuator element is transferred to the swi-tchoperating arm 55 and the same is moved. in. a direc-tion to cause the motor to move the carriages. 9 and 1-5 toward the end frame member 5 until. the. carriages reach their positions P1 and S1 of l. of the carriages 9 and lthe stop dog 89 successively engages. the cam-acting surface 76 of eachA abutment element 74 andis cammedzdownwardly thereby so that the4 stop. dog moves past the abutment. elements 74 without causing stoppage of themotor 44 during its return operation. When the carriage 9 reaches its position P1 of. Fig. l, the stop dog 39 engagesthestop cellar 94. and moves the samein a direction to cause the actuator stem 97 and actua-tor element.109to Ibe-movedto their idle position inthe reverse. action zone.. it will be noted that, during the. return movementfof the carriages 9 and 15, the double length vof border strip Bl lsupported lby the roller 13 and supporting stem-18. becomes draped thereover as shown in Fig, 2. After theearriages havearr-ived at their. positions. Bl and S1, the border stripis then severed from the rollythereof and at apoint to malte same of the proper length. Preferably, this is accomplished by a conventional cutter comprisingrela-tively movable andl stationary blades 121l and. 122 respectively. As shown in Figs. l and 2, the cutter 12iris mounted on the end of lthe bridge 2 overlyingthe. end frame. 5.. After the length ofborder strip. has been severed, .the clamp 29 is released andthe .fihishedbiorder strip removed therefrom and from thevpulley 13' and supporting stem 16. lt will be noted by reference to Fig. 2 thatthe border strip B, -being draped over the pulley 13 and stem 18, the same is very easily removed therefrom and need not be further folded for transportation to a place wherethe ends of the border strip. arev sewn together.
