MACHINE FOR PLACING SPRINGS IN FABRIC JPOCKIETS.

Application tiled. may 9,

This invention relates to machines for making coiled springs and placing-same in pockets of fabric" strips.

One object of the invention is to co-ordinate a spring coiling device with mechanisms for filling fabric pockets with springs, and with spring fastening means, whereby a strip of fabric having a plurality of adjacent pocket sections may be rapidly and the springs secured within the pockets.

Another object is to accomplish this result by mechanism which shall, practically speaking, be automatic as well as continuous in operation.

To the accomplishment of these objects, the invention consists in the devices and combinations of devices illustrated in the accompanying drawingsand herein described; and more particularly pointed out in the subjoined claims.

These and other objects and advantages may be accomplished by means which may be generally described as follows:

A strip of suitable fabric, such for example as burlap, is fed continuously into and through the machine, being first folded longitudinally between its sides into U-shape, with the two laps superposed, The marginal portion of each lap is inturned. ll prefer to use a plurality of fabric partition members secured. preferably, by stitching, in spaced apart relation to the top and bottom layers of the fabric strip, thus forming a'plurality of pockets lengthwise of the strip.

Wire is fed continuously through a suitable coiling device, to form a helical or spiral spring, and as each spring is formed, the wire is severed, permitting the completed spring to pass into a funnel and then downwardly into a hollow frame to a reciprocating member which travels in the horizontal plane of the folded fabric strip. Each spring is compressed, while in the hollow frame, by a pair of compresor arms. the flanges of which a e caused to enter the hollow frame or tube d engage the spring. The tube has diametrically opposite slots for this purpose, whichl permit the compressor arm flange to rest upon the severed, coiled spring and'when the arm flanges are automatically caused to move downwardly through these slots, they push thespring through'the tubular member andcompress the spring so that the reciprocating member, which operates as soon as the spring 15 compressed and positloned opposite its end,

filled with springs pair of stapling rear. $er1a1 No. wane.

may push the compressed sprin or spread apart folds of the fa pair of pivoted jaws are the top and bottom layers of the tance, i. e., sufficiently to bring a pocket space into position to receive the next compressed spring. When these jaws are opened and returned to repeat this operation, the released spring will expand quickly, spreading apart the top and bottom layers of the fabric the proper distance,a part of the top and bottom volutcs of the spring at the same time entering the small pocket-recess formed between the inturned marginal parts of the fabricand the top and bottom layers, respec tively, thereof.

As the fabric strip continues to be moved by the gripping jaws, through the machine, the part or pocket section thus filled with springs is passed over a conveyor through a devices, the first one passing a staple through the top of the strip to secure one end coil or volute of the spring to the fabric, and the second one stapling the other end coil or volute in the other pocketrecess formed by the inturning of the other margin of the strip.

The various parts are synchronized so that the fabric may issue from the machine with substantially a step bystep or intermittent movement, the completed striphaving a'pluand having a coiled spring in.

he'fabm'a striplhe pocketed strip A the spring S in a familiar manner.

will be fed into one side of the machine in any convenient manner, as from a reel, or other source of supply, and will emerge from the other side of the machine with a spring in each pocket as shown in Figures 4 and 20.

The strip of fabric, such as burlap, or the like, indicated as a whole by the letter A, is moved in the direction indicated by the arrows in Figures 3 or 4. This strip is folded longitudinally, as at 1, into U-shape, to have an upper layer or fold 2 and a lower layer or fold 3. The outer margins of the strip are folded as shown at 4 and 5 and form two longitudinally extending parts which are inwardly turned against the

layers

2 and 3, respectively. When this strip is completed into pocketed form it will assume the appearance indicated on Figure 20. A portion of the top layer 2 and a portion of the bottom layer 3 will constitute the top and bottom, respectively, of the pocket, and the folded portion 1 and the adjacent portions of the top and

bottom layers

2 and 3, will constitute a back (3. Usually I prefer to separate the top and the

bottom layers

2 and 3 by transversely positioned, spaced apart, partition strips 7 of similar fabric, the ends of the partition 7 being secured to the top and

bottom

2 and 3, respectively, by transverse lines of stitching or other suitable means. These partitions 7, when used. will form the two sides of each pocket which, as shown, is a rectangularly shaped pocket having an open face. A spring S is positioned in each pocket, a part of the upper and lower volute or coil of the spring 100 entering the space between the inturned portions 4 and 5 and the top and

bottom portions

2 and 3, respectively, of the fabric, and being secured therein in any suitable manner, but preferably by means of staples 8.

The mechanism.-Referring now more particularly to Figures 1234, the major portion of the mechanism illustrated is suitably mounted upon a frame B, having a base 9, and carrying in suitable bearings an op- 1m crating shaft 10, which shaft is actuated by any suitable motive power, as for example from a belt 11 over pulleys 12 mounted upon the shaft 10.

The frame B is provided with a forwardly 116 extending table 13, mounted upon which is a vertically extending tube T secured by a bracket 14. Removably positioned upon the upper end of the tube T is a curved, hollow funnel 15 adapted to receive a spring S. A 12 suitable spring coiler of any conventional type is designated as a whole by the letter C, said device being adapted to receive spring wire 16 from any source of supply and by means of a coiler head 17 convert the wire iInto he spring coiler C, per se, being no part of the present invention, except in combination as a whole with co-operating parts of the machine, need not be further described. When tween them.

Fabric fold spmadn-Mountcd upon the end of the table 13 and extending within the path of the moving folded fabric strip A, is.

a hollow spreader block 19 of an interior diameter sufficiently large to permit of the coiled spring S, when compressed, to be pushed therethrough. The two

folds

2 and 3 of the oncoming fabric strip ride over the top and below the bottom of the spreader block 19, 'as will be understood by reference to Figures 3, 5 and 13. Extended at the front end of the machine beyondthe table 13 is a second table 20, supported upon a standard 21 which may rise from the base 9. On this table 20 and near the end of the table 13 is a I vertically extending, supporting bracket 22 which carries and supports an inwardly opening, ill-shaped clip 23. The upper and

lower layers

2 and 3 of the incoming strip A are fed between the arms of theclip 23 and, as before stated, over and under the spreader block 19. When the compressed springs is pushed into the folded fabric between the

laps

2 and 3 thereof, the clip 23 holds the parts together against the expansion tension of the spring, as clearly shown on Figure 13. Two pairs of rotatable rolls 2 1,25, having engaging pins or teeth, located near either side of the spreader block'19,engage the folded fabric and hold it inproper position over the spreader block 19. a

Spring compreasion.-$Feferrin now more particulary to Figures 1314 and 15, it will be seen that the compression of the spring S is effected by the following mechanism: The tube T is provided with diametrically opposite, longitudinally disposed slots 26. @n' each side of the tube T and adjacent to said slots 26 is a rotatable shaft 27, each carrying a cam 28. Un each side of the tube T, and in operative position to be engaged by the cams 28 are the'arms 29, each pivoted at its upper end at 30 ton vertically movable bar 31, which moves in guides 31'. When the arms-31 are in their uppermost orraisedposi-' tion, the lower ends of the arms 29 are in the position shown on Figure 141;, having been forced into this position by the action of the cam 28, engaging lugs 32 on the outside of the arms 29. The lugs 32 on the arms 29, when I in contact with the cam28, function to quickly force the lower endsofthe arms 29 into the slots 26, so that the spring S Wlll beneaaaai held up and prevented from falling to the bottom-of the tube T until the predetermined time. The lower portion of each arm 29 has afootpiece or flange 33 of a width sufficient to enter and to slide vertically through the elongated slots 26 of tube T, and of a length sufiicient to enter into the interior of the tube T when in the position shown in Figure 14, whereby the flanges 33 will engage a severed spring and hold it upwardly within the tube T. When the shafts 27 rotate the cams 28 to a certain point and release the arms 29, and the bar 31 is moved downwardly (as hereinafter explained), said arms 29 move downwardly also, and the'flanges 33 thereon push the next subjacent spring downwardly until said spring is in the compressed position shown in the bottom of the tube T on Figure 15. Tn said Figures 13, 14 and 15, the spr ng S, as formed and about to pass through the funnel 15, is given a separate designation as S and said spring will be held up in the upper part of the tube T by the flange 33 as indicated 'on Figure 14. The spring com pressed is given the designation on Figure 15,

of S and the spring next to be compressed is given thedesignation S. In other words, when the spring S is moved away the spring S is nextcompressed and the spring S drops a upper part of the frame B, a rotatable shaft 34 carries a gear 35, the outer face of which is provided with a cam 36. The short arm of a rocking lever 37 is in operative engagement with the cam '36, the lever 37 being fulcrumed at 38 to a supporting bracket 39 on the frame B. The longer arm of this lever 37 bears against an antifriction roller 40 mounted at 41. in the end of a plunger rod 42, which latter ismovably positioned upon the table 13. The lower partof the tube T is provided with diametrically positioned apertures 43 of sufficient size to permit the end of the plunger rod 4:2;when actuated, to pass through one aperture 43, contact with the compressed coiled spring S and push the latter bodily ahead of it through the other opening 43 between the separated

laps

2 and 3 of the fabric as before explained. The

ment of the plunger places the spring 44:

under sufficient tension to cause the prompt return of the plunger to its normal position where its end will be ready to engage the spring next compressed in the tube T.

Gripping and feeding m o ement.-The feeding of the fabric strip through the machine is accomplished by step movement through a pair of gripping jaws, which take hold of the spring filled pocket and by bodily movement, transversely of the machine, carry the strip longitudinally a predetermined distance; 1. e., a distance equal to the width of the pocket, so as to bring the folded, spread apart folds 2 and 3 of the fabric into the proper position for a compressed spring to be inserted therebetween. Then these jaws are opened. the fabric released, the jaws re- 1 7 turned to their initial position, ready to grip the fabric containing the next adjacent spring to repeat the operation. The gripping jaws are positioned at one side of the clip 23, so as to take hold of the fabric strip with the compressed spring therein, and draw the strip out away from the clip 23.

Referring more particularly to Figures 10, 11 and 12, Twill first describe the gripping devices, which consist of two vertically

movable jaws

46, 46, spread apart and fulcrumed at 47, 47, upon a standard 48. Between these normally to hold apart the gripping ends of the jaws 46. These ends 46 carry plates 50 sufliciently large in area to cover the spring of largest diameter that is to be used in making the strips. The under side of the plate 50 is provided with pins 51 adapted, when the arms 46 are closed, and the plates 50 embrace the folded spring-filled strip, to prevent the fabric from slipping between the plates and to carry the fabric with the plates and the jaws as the latter are moved bodily. The opposite ends of the gripping jaws 46 are spread apart and so shaped as to be operatively engaged by a plate 52 one end of which is wedge shaped, as indicated at 52 and mounted on the end of a reciprocating member 53. When the wedge 52 is inserted between the jaws 46, the tension of the spring '49 is overcome and the

gripping plates

50, 50, are brought together. When the gripping jaws 46 are moved transversely of the machine, as hereinafter explained, the ends 01)- posite the gripping ends ride over the wedge :52 and'by the tension of the spring 49 are forced towards the flat plate 52, whereby the fabric strip and spring are released and the gripping jaws may be returned to their original position.

In Figures 10 and 12, the jaws 46 ave started to open, the spring S held between the plates 50 has been partially. released. Iii Figure 11 the jaws have entirely separated, the spring S has been expanded to completely fill the pocket and the mechanism is in position to be moved laterally to the left hand, as shown in Figure 12, so as to repeat the movement as above explained.

Referring now to Figure 7, the reciprocating member 53 is actuated by themove'ment of the rocking arm 54, fulcrumed at 55 upon a bracket 56, which extends out from the table 20. A reciprocating arm 57 is held upon the under side of the table 20 by any convenient means, as for example, by a pair of downwardly projecting, spaced apart lugs 58 on the table 20, the bar 57 being held in position by a cover plate 59. This bar 57 carries on its short member 60 an adjusting screw 61 which latter engages one end of the rocking arm 54. The adjustment of the screw 61 enables me to determine to a nicety the amount of lateral movement to be given to the wedge 52 to open and close the aws 46.

The inner end of the bar 57 is adapted to be engaged by the cam surface 62 on the face of the block 63, mounted upon a rotatable shaft 64.

WVhen the block 63 is rotated, the cam 62 pushes the bar 57 so that the rocking arm 54 moves the wedges 52 inwardly against the tension of the springs 65.

The table 20 is provided with an upwardly extending member 66 which provides means for supporting and forms a seat for the reciprocating bar 53. One end of the springs is attached at 67 to the member 66 and the otherend of each spring is attached at 68 to the wedge 52 (Figure 4). It will be understood that when the rocking arm 54 moves the wedge forward, the springs 65 are stretched and put under tension, and when by the rotation of the cam block 63. the end of the arm 57 is disengaged from the cam surface 62. the springs 65 very promptly pull the wedge 52 from the position shown in Figure 10 to the position shown in Figure 11, thus the rocking arm 54 is reversed and the bar 57 returned so that its free end may be engaged by the cam 62 for the next succeeding cycle of motion.

The gripping aws 46 and associated parts, however, have another movement, transversely of the machine, as stated, for the purpose of feeding the spring filled strip through the machine. ,This is accomplished by the following means: The standard 48 is secured to a plate 69 from which depends a. pin 70. The plate 69 is held upon the table 20 by a pair of L-shaped guide bars 71, as clearly shown in Figures 4, 7, 10 and 11. The table 20 is pro vided with an aperture 72, through which the pin 70 extends, said pin being of suflicient length to enter a recess or cut awayportion in the block 63 and to have its end engaged by and operated from the cam surface 73 which constitutes the bottom of the recess. It follows that when the shaft 64, carrying the block 63, is rotated, the cam surface 78 will move the pin 70 and therefore the plate 69 a distance sufiicientto bring the gripping jaws 46 from the position shown in full lines to the position shown in dotted lines in Figure 6. The return movement fromthe dotted position to the full line position is acc0mtceaati plished by the contracting of the spring it,

which at one end is secured at? to the plate the reciprocating. movement of the plate 69.

lln order to limit the extent of movement of the plate 69 in the guide ways 71, the adjust ing screw 7 8 is mounted in a suitable aperture in the table 20, its end extending into the aperture 7 2 so as to be engaged by the pin '10 and thus limit the movement in one direction of the plate 69. This arrangement permits of adjustment so the gri ping jaws will grasp a pocket and spring an move the strip a distance equal to the width of a pocket.

Sm ling mechanism-After the strip has been lled with springs, one in each pocket, the intnrned edges 4: and 5 of the fabric and the springs S are suitably fastened together. This may be done by stitching or by using a hand staplinghimplement, but prefer to use conventional stapling machines such asarc on the 'marketand available for such purposes. Two of such machines are illustrated in Figure 4L, and desi nated as a whole at 7 9,

80- The first stapleril'9 is located so as to be in the path of the strip with springs in the pockets, adapted to engage the upperlap 2 and the inturned margin 4 of the strip, and to all!) till inser the staple 8 therein as shown in Figure 22, e other stapling machine 80 is on the opposite side of the strip A. In order to present the lower lap 3 to the machine 80, ll

locate the latter a sufficient distance from the stapler 7 9 to permit of twisting the strip half way round. This twisting takes place between the twostapler machines at the broken awa part of the strip, as indicated inlFigure a. i. uch half-twistwill present the lower lap 3 of the strip uppermost so that stapler 80 may operate thereon upon the inturned margin 5 and lap 3. The staplers may be actuat ed by any suitable mechanism. A double stapler, with its operating mechanism spaced a art the height of the strip, may be used in p ace of two staplers.

Driving meoham'sm.ldeferring now to the mechanism for driving or transmitting motion to the various parts heretofore referred to, the spring compressor arms 29 are recip rocated by the following. mechanism :--the belt 11 over pulley 12, mounted on shaft/10, driving the gear 81, which meshes with the pinion gear 82, through gear 83-, and gear 84 on shaft 85. The driven shaft 85 carries a arm. 87- adjustably secured in the slot by means of a bolt and nut 88. The arm 87 is pivotally connected to a cross piece 89, which is connected at each end to one of the vertically movable bars 31 which travel in the guide ways 31 By this mechanism the compressor arms 29, pivotally connected to the movable bars 31, are given the reciprocating motion heretofore described. v

The horizontally arranged shafts 27, which carry the cams 28, are driven by the following mechanism; a gear 90 on the shaft 10, meshing with gear 91, through gear 92, on shaft 93, said shaft carrying gear 94 in mesh with gear 95, through two idler gears 96 to gear 97, on shaft 27.

The plunger 12 is reciprocated in a horizontal plane, as heretofore explained, by the action of the cam 36 in operative connection with lever 37. This cam 36 on the gear 35 is rotated by the belt 11, over pulley 12, on shaft 10, carrying pinion gear 35 which meshes with the gear 35 on the shaft 3 1.

The shaft 64 is rotated through pinion gear 82, meshing with gear 83 on shaft 98, carrying a sprocket wheel 99, sprocket chain 100, meshing with sprocket gear 101, on the stub shaft .102, through sprocket wheel 103, sprocket chain 104: to the sprocket wheel 105 mounted on the shaft 64:.

Counc l or-The shaft 64 carries a sprocket gear 106, which, in turn, works sprocket chain 107 which meshes with sprocket gear 108 on shaft 109, mounted-on a standard 109, rotating the pulley 110, which carries the conveyor belt 111. This conveyor belt carries the spring strip to the stapling device heretofore described.

It will be manifestthat the springs may be secured in the fabric pockets by means other than the stapling devices described. For instance, a sewing machine maybe used for this purpose.

It will also be obvious that the machine may be used for placing springs in the pockexample. 1 refer to astrip such as that shown in the Marshall Patent. No. 685,160.
