8 Claims.

The invention relates to mattress stitching machines, and particularly to machines for prebuilding mattress quilts wherein a plurality of plies of material are stitched together to be used in a mattress or the like.

The invention has among its objectsthe production of a machine which will perform a plurality of operations simultaneously as, for example, iorming a plurality of lines of stitching securing a plurality of plies together simultaneously. I

Another object of the invention is the construction of a machine which will make some types of unitary cover pads for mattresses and the like, in one operation.

Another object of the invention is the production of a machine of the kind described which will not only secure the various plies of the pad together, but will also secure attaching means thereto at the same time.

A further object of the invention is the production of a machine of the kind described which may be readily adjusted to provide for various forms of stitching as well at producing parallel rows of stitching spaced any desired distance from each other.

Another object of the invention is the construction of such a machine in which adjust-- ments may be made accurately in a minimum of time and in which only one major adjustment of the machine is necessary, thus providing a machine which is extremely flexible in operation.

A further object of the invention is the production of such a machine in which the component elements of a cover pad may be accurately aligned with one another and securely held in place during the stitching operation.

Another objection of the invention is the novel method of constructing unitary cover pads and the like for mattresses.

A still further object of the invention is the production of a machine embodying novel means for guiding the components of the cover pad or similar member through the machine during the stitching operations.

Another object of the invention is the production of such a machine which is durable, simple A in construction, and eflicient for the purpose intended.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

Referring to the drawings andmore particularly to Figs. 1, 2, and 3, l and 2 generally rep-- resent tables having tops 3 and 4 positioned end to end. These table tops carry sewing machines 5 and 6, respectively, which may be of any suitable type. These table tops are supported by the members 1, 8, 9, and II), respectively, which may be constructed of any suitable material, and as shown in the drawings, are U-shaped members having connecting braces H and ['2 .of angle iron connecting the legs 1' and 8, respectively, braces I3 and I4 connecting the members 9 and Ill, respectively, thus providing rigid supporting means for the table tops. The supporting members-l and 8 are connected by the L-shaped members I5 and I6, respectively, the latter members being provided with grooved rollers pivotally mounted on the upright portions of the members [5 and I6. Similar L-shaped members Iii-and 19 are rigidly attached to the floor, the vertical walls of these members engaging the grooves in the rollers I'I, thereby providing a track along which the table I may be moved. A similar table 2 is provided with members 2| and 22 having corresponding rollers 23 adapted to engage the track members I8 and Hi. It will thus be seen that I have provided two tables each carrying a sewing machine mounted thereon, said tables being movably carried upon supporting tracks whereby the tables may be moved to or I away from each other, thus positioning the sewing machines closer to or farther from one another as the case may be, and in this construction, it will be noted that the only change in the operation of the machines will be that the lines of stitching made thereby will be spaced closer to or farther from each other. Mounted on the brace members H and I2 are the hangers or bearings 24 and 25, respectively, which carry the drive shaft 26, the latter being driven by the motor 21 through the clutch 23, pulleys 29 and 3| and the belt 32 connecting said last mentioned pulleys. The sewing" machine is in turn driven from the shaft 26 by any suitable means, for example, sprockets 33'and 34 and chain 35. Connecting the brace members I3 and I4 of the table 2 are members '36 and 31 formed'of angle iron or other suitable material and which carry the hangers or bearings 38, 39 and 4 I. The shaft 26 extends through thebearings 38 and 39 at all times and depending upon the relative positions of the table mayor may not extend through the bearing 4|, the latter being designed merely to support the end of the shaft 26 when the vided with an integral key adapted to engage a suitable slot 43 located in the shaft 26. In this construction, the shaft 26 and the slot 43 slidably engage the gear 42 whereby the shaft 26 is free to slide laterally through the spur while at all times maintaining a positive driving cone nection therewith It will thus be seen that no matter how far the tables may be extended from each other within the limits of the machine, the shaft 26 will continue to drive the spur 42, without any manual adjusments, etc. Also mounted on the brace members I3 and I4 are bearings 44 and ,45, respectively, journalling the shaft 46 which is positioned parallel to the shaft 26. Rigidly carried by the shaft 46'is'a spur 41 similar to the spur 42 and engageable therewith, whereby the shaft 26 will also drive the shaft 46 but in the opposite direction. The sewing machine 6 is driven by the shaft 46 through any suitable means, as for example, sprockets 48, 49 and the chain 5| similar to the sprockets 33 and 34 and chain 35.

It will be seen from the above that I have provided positive means for driving the two sewing machines at all times regardless of whether the tables I and 2 are positioned close to each other or relatively farther apart and in which no changes or adjustments are necessary to perform this function, the same being accomplished automatically as the tables are separated. Rigidly mounted on the members I8 and I9 are legs 52 which in conjunction with the legs 53 support the smaller stationary tables 54, 55, 56, and 51 and may be provided with brace members 58 of any suitable material and, as shown, are formed of light angle iron similar to that used in the 6 legs 52 and 53. Likewise, connecting the top of rigidly attached to the table 2.

the legs 52 and 53 and supporting the table tops are members 59 similar to the braces 58.

Extending across from the track I8 to the track If! are shafts 6| and 62 suitably journaled on hangers 63 and 64, respectively, which may be mounted either directly on the members I8 and I9, or, as shown, on the legs 52, the shafts being mounted in either case on members which are stationary relative to the tables I and 2. Sprockets 65 and 66 on the respective shafts 6| and 62 are connected by an endless chain 61, the lower portion of this chain being securely attached to the cross brace 68 by means of a bolt 69 or other suitable means, the brace 63 being Likewise, the upper portion of the chain is secured to the U-shaped member II by means of the belt 12, said U-shaped member being in turn rigidly attached to a corresponding brace 73 rigidly connected to the table I. A hanger l4 likewise mounted on a stationary member which as shown is one of the legs, carries a shaft 18 and sprocket I5 which is connected to the sprocket I6 located on the shaft 6| by means of the chain TI. The sprocket I5 may be connected with any suitable crank or handle I5 carried by the hanger 14 so that as the shafts 6| and 62 are rotated thereby, the upper and lower portions of the chain 61 will be moved in opposite directions, and as these portions are attached to the table and the table 2, respectively, said tables will be moved toward or away from each other depending on the direction of the rotation of the shafts. Likewise, each table will be moved the same distance to or from the center line of the machine.

As shown in Fig. 5, a clamping bolt 15 may be provided to clamp the shaft 76 to the hanger I4, thereby preventing shafts BI and 62 from rotating to lock the tables and 2 in any given position. Obviously, if desired, the bolt I9 may or may not be provided with a handle as desired, a wrench being used if it is merely provided with a head, as shown in Fig. 5.

As shown in Figs. 3 and 1, extending from the top 54 to the member 55 is an inverted T-iron 8| and similarly extending from the table 56 to the member 51, is a corresponding inverted T-iron 82 thus providing a track for the carriage, to be hereinafter described.

A rectangular carriage 83 formed of angle iron or other suitable material is provided, and attached thereto are a plurality of rollers 84 adapted to engage the tracks 6| and 62 by means of which the carriage 83 may travel from the stationary tables 55 and 51 past the sewing machines to the tables 54 and 56, as shown in Fig. 3, the arrow indicating the direction of feed through the sewing machines. The space between the vertical legs of the angle irons of the carriage 63 provides a receptacle for a materialcarrying frame. As shown in Fig. 6, a frame 85 of wood or other suitable material is provided, and extending across the frame are cross members 86 which are of a length to engage and rest upon the carriage 83, and to closely fit within the vertical legs of the angle irons forming the carriage, as shown in Fig. 3. The frame 85 is designed to carry the components of the mattress cover pad and maintain them in proper relation while they are being stitched together by the sewing machines 5 and 6. The cover pad illustrated in Fig. 6 is designed to have two parallel rows of stitching 8i and 88 which divide the pad into three parts, and itwill be noted that the cross members 86 must necessarily be positioned between said rows of stitching. If the pad were to have a different number of lines of stitching, obviously, it might be necessary to use a frame having the cross members 86 positioned differently so as not to conflict with the lines of stitching and may, if necessary, be positioned at the ends only. To maintain the component parts of the cover pad in proper relation on the frame 85, suitable fastening means is provided, the same being shown in detail in Fig. '7. This fastening means comprises, essentially, a fiat plate 90 mounted on the end members of theframe 85. A sharp pin or needle 91 is pivotally connected to the plate 90, as shown at 92, wherein the plate 90 is bent around to encircle the pin 9 I An inverted L-shaped member 93' is mounted on the frame 85 adjacent the sharp end of the pin SI, and is free to rotate about its vertical axis whereby it may be rotated around, as shown in Fig. 7, to allow the cover pad plies to be hooked .on the end of the pin, after which the member 93' may be rotated until the horizontal portion of the member overlies the end of the pin 9i, as shown in Figs. 6 and 8, thus locking the pin 91 in proper position. However, any suitable means for fastening the plies of the cover pad to the frame 85 may be utilized.

When it is desired to attach securing means to the cover pad, for example, a strip of material 94, as shown in Figs. 9', 10, this operation may be accomplished at the same time the various plies are stitched together and provision is made on the machine for feeding a ribbon beneath the cover pad plies and stitching the ribbon thereto, all in one operation. To accomplish this, spools 95 and 96 are provided and are carried by the inverted L-shaped rods 91 which are anvaece mounted on the brace members [2 and I3, re-

spectively. A flat U-shaped member 98' guides the ribbons from the spools 95' and 95 to the 1 table tops I and 2, and the mechanisms 5' and 6',

respectively.

The operation of the machine is as follows: First, the tables I and 2 are moved to or from each other as the case may be by means of the crank until the proper spacing between the lines of stitching is obtained. The component parts .or plies of the cover pad desired to be stitched are then positioned on the frame 85, which may be positioned on another table for convenience and so that one pad may be prepared for the machine while another one is actually being sewed thereon. The plies of the pad are hooked, one after another, by means of the sharp pins 91. The inner ply IE0 is hooked first and the cover sheet Hll last with a layer of padding I02 interposed between the two if desired. If desired, when the cover sheet is provided with a looped portion 103, a rod I04 may be inserted in the looped portion to reinforce the edge of the cover sheet and maintain the same evenly and uniformly on the frame 85. The frame 85 carrying the coverpad is then placed in the carriage 83 which is positioned adjacent the tables and 51. If it is desired to attach a securing strip 94 to the underside of the pad, said strips are drawn up under the pad past the needles on the sewing machine. The sewing machines are then adjusted and the usual clamping foot ofeach machine lowered to engage the cover sheet, as shown in Fig. 3, after which the clutch 28 is engaged by means of a rope or other suitable means which will start the sewing machines and will stitch the various elemen-ts together, as shown in- Fig. 2.- Ordinarily,

the feeding movement of the sewing machines will be suiiicient to draw the cover pad through the same although, if desired, the operator may slightly urge the carriage 83 along the direction of the arrow and thus overcome the friction of the rollers 84, etc. After the stitching has been completed, the sewing machine feet are raised andthe carriage drawn as far upon the tables the machine may be run practically continuously very little time lost for adjustments or changing from one piece of work to another. That is, while one cover pad is being run through the machine, the pad finished and stitched prior thereto is being taken off a frame 85 and at the same time another pad is being prepared for the machine on another frame. Likewise, I have provided novel means for quickly and accurately varying the distance between the lines of stitching, and also for securing a strip or the like to'thepad simultaneously with the stitching operation. I- have also provided the novel method of constructing unitary cover pads and the like for mattresses.
