UNITED STATES PATENT OFFICE.

JOHN D. PIERCE, F CHICAGO, ILLINOIS, ASSIGNOR TO COMBINATION WOODWORKING MACHINE C0., OF CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS.

MATTRESS-MAKING MACHINE.

Application led February 19, 1920.y Serial No. 359,923.

To all whom it may concern.'

Be it known that I, JOHN D. PIERCE, a citizen of the United States, residing at Chicago, in the county of Cook and Sta-te of Illinois, have invented a certain new and useful Improvement in Mattress-Making Machines, of which the following is a full, clear. concise, and exact description, reference emg had to the accompanying drawings, forming a part of this specification.

My' invention relates to apparatus for makingqnattresses, pads, cushions and similar artlcles.

One of the objects of the invention 1s to provide a simple and practical machine for manufacturing bed mattresses and similar articles.

Another object of the invention is to make mattresses or similar articles automatically and in'regular and rapid succession, supplying the machine with the raw material of which the articles are to be made and with- Vdrawing the articles in a nearly completed condition.

Other objects of the invention will appear and be pointed out hereinafter.

In the accompanying drawings Fig. 1 is a side elevation of an end portion of a machine for making mattresses or like articles embodying my invention;

Fig. 2 is a side elevation of the other end portion of the machine;

Fig. .3 is a plan view of a part of the machine;

Fig. 4 is a side elevation of a portion of that part of the machine which is shown in Fig. 2, on an enlarged scale;

Fig. 5 is a transverse vertical section taken on line 5-5 in Fig. 2; Fig. 6 is an elevation of the portion of the machine shown at the left handv end of Fig. 2;

- Fig. 7 is a vertical section taken on line 7-7 in Fig. 2;

Fig.Y 8 is a view of a modification of the arrangement shownv in Fig. 6; Fig. 9 is a vertical section 9 9 1n Fig. 2;

- Fig. 10 is a cross section of a detail of construction; and

Fig. 11 is an elevation of a detail of construction. o

Referring to the drawings and especially to Figs. 1 and 2, I show a machine having taken on line' machine which end is shown in Fig. 1, there is assembled the mechanism for holding and preliminarily feeding the material of which the mattresses or other articles are to be made. In the right hand end of the machine which is shown in Fig. 2, there is the mechanismr for actually making the mattress from said material and delivering the nearly completed articles.

Referring first t'o Fig. l, there is shown a series of vertically arranged `belts or like devices 5-5, six being shown in the present machine. TheseV belts 5 are provided at intervals, with claws or hooks 6-6 which provide holders for the sticks or rods 7 on which the mattress material 8 is rolled. These holders 6-6 are disposed at intervals on said belts 5 and bundles or rolls of the material 8 are supported in said holders 6 by said belts 5 in position one above another. In the drawings each belt 5 is shown pnovided with two rolls 8. It is understood that the belts 5 extend upwardly and may be as long as desired so as to carry as many rolls 8 as desired, and that additional belts may`be used if desired.

The material from the rolls 8 is fed horizontally from the lowermost rolls, the strip. of material over the lefthandmost roll 8 being lowermost and the strips of material over the rolls successively to the right being next in position above said lowermost strip. Thus the strips from the six lowermost rolls come into position one above another in a horizontal manner as well shown in F ig.' l, and these strips so assembled form a continuous body or length of mattress material made Vup of six layers arranged one above the other.

the end-of the preceding roll, whereby each strip or layer 1s kept continuous, made up of a series of strips one after the lgther. The bundles or rolls are in various degrees run out at different times, whereby the joints between successive strips forming each layer of the mattress body are staggered with ref'- erence to one another, and hence the mattress body is practically continuous with joints here and there, separated from one another, in the different layers.

The belts 5 are shown preferably composed of sprocket chains and mounted at their lower ends on sprocket wheels 10 carried on shafts 11, which latter are suitably mounted in the framework in the machine.

The continuous length of material for the mattresses rests upon a traveling belt or platform 12 which is mounted at one end on a roller 13 and at the other end on a roller 14. There are intermediate supporting rollers 15 located underneath the material holding devices, and also a series of rollers 16 arranged close together and at the right of said rolleIS 15; i l

There is also another set ofV rollers 17 mounted above the rollers 16 but arranged at an inclination to the latter. These rollers 16 and 17 serve to compress the layers of material 8 8 and reduce the thickness of the same. A substantial reduction in thickness is preferably secured, as shown by reference to the right hand end of Fig. 1, and the left hand end of Fig. 2. Both sets of rolls 16 and 17 are preferably power driven or rotated so as to advance the material and compress it as it moves from left to right, referring to'Figs. `1 and 2. To such end, driving mechanism is p provided as best shown in Fig. 6. The traveling belt 12 is arranged to travel on top of the rolls 16 and over the end roll 14 which is on a shaft driven preferably by achain 20 from a power shaft 21. The rotation of the roll 14 causes the movementof the belt 12 and the upper part of said belt travels over the tops of the rolls 16 and underneath the mattress material, advancing the latter as said upper reach or stretch of said belt 12 advances. The shaft carrying. roll 14 is gear connected by gears 22 with a shaft carrying a roll 17, situated immediatelyabove the roll 14. A belt 24 passes over the roll 17 and also above and below rolls 17, the left-hand-- most roll 17 being adjustable to take up slack of belt 24. The roll 17 is thus driven ing belts cooperating therewith, thus serving.

to advance and compress the mattress material from the thick conditionA shown in Fig.-

1 to the relatively thin condition shown in Fig. 2.

After passing between vthe rolls 14 and 17', the length of mattress material passes between two other sets of rolls 27 and y28. There are-preferably a, substantial number, as for example, seven, rolls in each of these sets 27 and 28, and if desired these two trains of rolls may be provided with belts as the rolls 16 and 17 are.

Above the rolls 27 is a reel 29 and below the rolls 28 is another reel 30, and these reels 29 and 30 are provided with cloth 31 which' is adapted to form the outside of the mattress filling, but inside of the ticking. The cloth 31 is extended from the reels 29 and 30 running from the reel 29 underneath the rolls 27'and between the same and the length of mattress material, and similarly the cloth 31 from the reel 30`extends upwardly and over the tops of the rolls 28 and between said rolls and the length of mattress material. Thus the rolls 27 and 28V grip and advance the two strips of cloth 31 along with the length of mattress material which is interposed between them. The rolls 27 and 28 are driven by a chain 32 driven by the main drive shaft 33 (Fig. 4), the chain 32 passing over and driving a` sprocket wheel 34 on the shaft28` carrying the endmost roll of the series, 28. Said shaft 28 is provided with a sprocket wheel 36 which drives a sprocket chain 37 meshing with sprocket wheels 38 on the shafts'carrying said rolls 28. The upper reach or stretch of the chain 37 engages said sprocket wheels 38 so as to drive said rolls 28, whereas the lower reach or stretch of said chain 37 is held away from said sprocket wheels 38 by a small idler 40,-thereby preventing interference between said chain 37 and the under teeth of said wheels 38. The upper rolls 27 are driven by a sprocket chain 41 which engages the upper sides of sprocket wheels 42'-42 on the shafts carrying said rolls 27. The right hand upper sprocket 42 is driven by a gear 43 which is inv turn driven by a gear 43a' on the shaft carrying the right hand roll 28.

yFurther along to the right, referring to Fig. 2, there are other sets of rolls 47 and 48, 49 and 50, and 51 and 52. Each of these sets or trains of rolls preferably has a separate belt (not shown). Between the rolls 47 and 49 there is a stitching device 53 for stitching or sewing the various layers of material together. Between the rolls 49 and 51 there is a cuttin device 55, for cutting the continuous lengt of material into pieces or lengths each sufficient for a mattress. Beyond or to the right of the rolls 51 and 52 the mattress is projected through a funnel int-o an outer covering or tick arranged on the outside of said funnel, making it nearly ready for use and is then discharged. u

Reference will now be made to the stitchingr mechanism 53.by which the layers of cured to eac felt or similar material forming the continuous length for the mattress are stitched together. This stitching mechanism is shown more in detail in Figs.- 4, 7i and 11. It comprises a plurality `of stitching devices or needles 60 carried at the ends of the vertically reciprocating rods 61 which latter are arranged to slide in suitable apertures or guideways in a cross beam or frame 62f The rods 61 are operated by a series of cams 63-63mounted on a rotary shaft 6 4 and having annular recesses 65 in which projections 66 on the upper ends of the rods 61 fit andwork. Thus the rotation of the shaft 64 will cause the cams 63 to raise and lower the rods 61 and thereby operate the stitching devices or needles 60. The shaft 64 is-rotated by means of a master wheel 68 mounted on a shaft 69 supported by pillars 70 rising from the machine frame. This master wheel 68 is provided with a series of sets of gear teeth 71-- 71 and 72-72. The rotary shaft 64 is provided with agear 73 adapted to mesh with and be operated by the gear teeth 71 and 72. Thus as the wheel 68 rotates the sets of teeth 71 and 72 will engage the gear 73 and rotate the shaft 64'so as to operate the stitching devices 60, each set of teeth 71 and 72 beingcapable of giving the shaft 64 onecomplete rotation and thereby imparting one complete Vertical reciprocation or stitching movement to the needles 60.

The-sets of teeth 72-72 on the wheel 68 are preferably located at about equal distance from one another so that the stitches resulting from these teeth will be separated about the same distance in the body material of the mattress. The teeth 71-71-however are closer together and to the adjacent sets .of teeth 72, so that. there will be two stitches taken close to one another and4 also close to the other stitches, so that when the continuous length of material is cut into different parts or sections to make up theindividual mattresses, these individual sections will each be provided with a stitch quite close to the line of the cut and therefore close to the end of the cut sections of material, these extra stitches being for, the purpose of -fas tening the loose ends of the threads.v

There is also preferablyprovided in connection with this stitching mechanism a;

presser plate 75 located just above the mattress material (Fig. 7), and having apertures through which pass the needles 60.

'This presser plate is preferably connected with mechanism by which it may be automatically lowered to come in contact with and press upon the top surface of the mattress material, just prior to keach stitching operation. This mechanism comprises'vertically reci rocating rods 76-7 6, one seli end of the presser plate 75 and each rod 76 being operated bly a cam 77 also mounted on the rotary vshaft 64, the rods 76 having pins 78 traveling in annular recesses 79 in the cams 77, The pins 78 move in guideways or slots 80 .(Figs. 4 and 7) and said rods 76 are also preferably provided with other pins 8 1-81 which also travel in the slots or guideways 80 and serve to guide s vplate 75 just before each stitching operation, so that the material is compressed and firmly held while being stitched.

As previously explained, there are a series of rolls 47 at one side of the stitohing'mechanism and another series 49 at the other side of the same, as well as other series 48 and 50, respectively, below the rolls 47 and 49. These rolls` are driven by suitable gear and sprocket chain arrangements, as shown .in Fig. 4, there being sprocket wheels 84-84 on the rolls 47, sprocket wheels 85 on the rolls 48, sprocket. wheels 86 on the rolls 49, sprocket wheels 87 on the rolls 5() and a sprocket chain 88 cooperating with the sprocket wheels 84 and 86 and another sprocket sprocket wheels 85 and 87. By this arrangement all the rolls above mentioned are rotated simultaneously to advance the continuous length of mattress material.

During each stitching Aoperation it is desirable to stop the advance movement of the continuous length of material so that the stitching may not be interfered with, and tosuch end I preferably provide means for automatically stopping that part of the material being stitched just prior to each stitch. This mechanism is best shown in .Figs 4, 7 and 11. It comprises a horizontally arranged stop pin 93 mounted in bearings 94-94 and adapted to slide back and forth so that its end may be engaged with and disengaged from the righthandmost sprocket 86.. This pin is controlled and actuated by a vertically arranged lever 95 havingla slot 96 in which a pin 97 on the end of the rod 93 fits and works. The lever 95 is pivoted at 98 and its upper end'95a extends up alongside the master wheel 68. wheel is provided with projecting members 99 forming abutments adapted to strike the upper end 95 of said lever 95 and thereby tilt or swing the same, the result of which isA to actuate the rod 93 to cause it to engage the aforesaid sprocket86. A spring 100 is carried by the rod 93 and arranged to cooperate with one of the bearings 94 and also with the collar 101 fast on the rod 93, said spring 100 being adapted to retract the pin 93 by'pushing it away from the sprocket 86. The projecting members 99 on the wheel 68 chain 89 cooperating with the This are located adjacent the various sets of teeth 71, 72, so that the lever 95 will be actuated and the rod 93 moiled to engage and stop the sprocket 86 and the sprockets 84, 85 and 87 connected with it by gears or chains as previously described, thereby stopping the advance movement of the mattress material just prior to each operation of the stitching mechanism. The stoppage of the sprocket wheels 8.4, 85, 86 and 87, during the stitching operation is permitted by suitable' joints or connections in the power transmitting train to said sprockets, so as to allow said sprockets to be stopped when desired bythe reciprocating pin or plunger 93 as previously described, without any breakage or interference with the rest of the mechanism,

and also to permit said sprockets to be' turned or rotated at a momentarily higher speed when said pin or plunger 93 is withdrawn or retracted to exactly make up for the time lost by the stoppage.

As an effective arrangement for accom-A plishing this result, I show (Figs. 9 and 10) a spring joint or connection on the shaft of the endmost roll of the series 28, from which power is transmitted to the rolls 48 by means of sprocket chain 89, Fig. 4, running over a .sprocket 102, which latter is mounted on a sleeve 103 loose on the shaft of said roll 28. A spring 104 forms a connection between the sprocket 38 and said sleeve 103, whereby said sleeve 103 with its sprocket 102 will be rotated by the shaft 28 under ordinary circumstances, but will be allowed to stop, permitting the shaft 28 to rotate without it,

when said sleeve 103 is held against vrotation by the insertion of the pin or plunger 93 between the teeth of the sprocket 86. The end roll 48 is also provided with a loose sleeve like the one shown in Figs. 9 and 10. These two loose sleeves are connected by a sprocket chain 48. v

lVhen the rolls 47, 48, 49, 50, 51 and 52 are stopped for stitching purposes, the rolls 27 and 28 are not necessarily stoppedbut are preferably permitted to continue their rotation. This causes the mattress material t0 be somewhat humped between the rolls 27,

28, and 47, 48, as shown in Fig. 2. This, however, is simply a temporary bending which is more or less straightened out when 107 mounted on a cross shaft 108, straps 109 enclosing said eccentrics and being pivotally connected with links 110, which are in turn pivotally connected as at 111 with the top of said support 105.' The shaft 108 is rotated at intervals in order to yeffect a complete downward and upward movement of the cutting device 55-to perform a complete cutting operation. This rotation of the shaft 108 is accomplished by a trip or clutch device operated by the master wheel 68, which mechanism is best shown in Figs. 2, 3, 4, 5, and 1l. The master wheel 68 is provided with a projection 113 which is adapted to strike a pin v114 on one end of a levei` 115 pivoted at 11G. The lever` 115 is connected with a rod or link 116a and the latter is in turn connected with a rocker arm 117. This rocker 117 is connected with a clutch device 122 which is arranged in connection with a belt driven fiy wheel 123 in such a manner that when the rod 115a is actuated the clutch device 122 will clutch the wheel 123 onto the shaft 108 and thereby rotate the same, the wheel 123 normally rotating loosely on said shaft 108.4 Thus when the projection 113 strikes against the pin 114, the clutch device 122 is actuated and the shaft 108 rotated, thereby causing said shaft 108 to be rotated and to aetuate the cutting blade 55, causing the same to de- -scend and immediately rise, thereby performing a complete cutting operation. The projection 113 thereupon travels a complete cycle vwith the wheel 68, and then again strikes the pin 114, thereby causing another cutting operation by the blade 55, enough of the continuous length of material for a mattress having advanced in the meantime.

A plate 130 is preferably arranged above the material and is provided with a-slot, not shown, for receiving the cutting blade 55 for guiding t-he blade in its vertical'movement. Located below the plate 130 on the lower side of the material is a support 131 having a groove formed on its upper face 1n vertical alinement with the cutting blade for receiving the cutter at the limit of its down stroke.

At the right of the cutting blade 55 (Fig. 2) the rolls 51 and 52 are located as previously mentioned, and these rolls are also driven by the sprocket chains 88 and 89, previously referred to, said rolls 4,51 and 52 being provided with sprockets 133 and 134, respectively (Fig. 4). The rolls 51 are preferably set at an inclination relatively to one another as shown in Fig. 2, whereby the mattress material is still further compressed. Said material is then advanced into the funnel 135 and then emerges from said funnel 135 and is pushed into a bag or tick 137 adapted to form the outside cover of al mattress. This bag or tick 137 is slipped over the funnel 135 so that the materal in emerging from the same passes into said bag or tick and pulls the same over and off of the said funnel 135, the mattress material expanding somewhat so as to fill the same and thereby make a firm and substantial mattress. As soon as one mattress has nearly emerged from the funnel 135, it is qluickly removed and another .cover is s ipped over the funnel 135, in time to receive and cover the next material as it advances, thereby causing said cut sections or portions of the mattress material to emerge as nearly complete mattresses.

A shelf or table 140 is preferably placed adjacent to the funnel at the right hand end of the machine (as in Fig. 2), so that the finished and completed mattresses can be p moved onto this table 140 quickly and may be removed from the same ,and transferred as desired.

Side guides or guide plates 141 are arranged along thel opposite sides of the ma,- chine so as to hold the material against being crushed out sidewise.

Referring to Fig. 8 I show a modified arrangement of the mechanism shown in Fig. 6. The mechanism shown in Fig. 8 is intended especially for making of mattresses or other articles out of excelsior, moss, husks, fibre, or other soft material not fclted in rolls, and having la ers of felt on the top and bottom, instead of ayers of felt throughout as in the apparatus already described. In Fig. 8 I show a-set or series of lower rolls 16 and an upper set or series of rolls 17 which are similar to Fig. 6, the excelsior 8 being fed between said two sets or trains of rolls. Upper and lower layers of felt 8a and 8b respectively are fed.' above and below the excelsior 8 and strips of cloth 31 are fed so as to come into position above and below the layers of felt 8a and 8", respectively, the sameas in Fig. 6. f Rolls 27a and 28 are arranged above and below the layers of felt 8a and 8b, in the'same manner as 27 and 28 of the other arrangement, as shown in Fig. 2. Thus thelayers of felt 8 and 8b may be accommodated and may also be compressed with the excelsior by the rolls 16 and 17 as well as the rolls 27 and 28. Plates 142 are interposed between the felt layers 8 and 8b and the rolls 17 and 16 respectively, so as to protect said :telt and layers from the oppositely moving belts on said rolls. Thus mattresses made of eXcelsior vcovered top and bottom with felt may be made.- It is evident that one layer of Afelt may b e omitted for-a still cheaper construction of mattress.

It will be understood that changes 'and modilications may be `made without departing from the spirit of the invention.
