METHOD OF MAKING A SEWN AND CEMENTED ARTICLE Filed July l0, 1937 Patented Feb. 6,' 1940 IMETHOD OF MAKING A SEWN AND CEMENTED ARTICLE 3 Rudolf F. Blavaty, Cicero, =l

Application July.' 10, 1937, Serial No. 152mm fIhis invention relates to an article and'te a process of making it.

It has' for one object to provide an article in whichseparate pieces of material are sewn and cemented together. Another object is to provide a process for securing together by sewing a plurality of pieces oi? material and for cementing the material together and for simultaneously cementing the sewing to the material and for cementing the stitches and contacting threads to each other and to the material.

In one form the invention comprises an article anda process of making it in which a plurality of pieces of material are sewn together and simultaneouslv with the sewing are cemented. In

another form the invention has for an object the provision ci a process by means of 4which non-fabric articles, such as buttons and their equivalents are sewn and simultaneously cemented to fabric articles such as clothand its equiva l lents. f

It is, therefore, within the objects of the present invention to produce the articles suggested and to carry out. the methods described.

Other objects will appear from time to time in the speciiication and claims.

The invention is illustrated more or less .diagrammatically in the accompanying drawing, whereinp Figure 1 is a section through a completed article formed by stitching together a plurality of i sheets of material;

Figure 2 is a similar section showing a modified form of stitch; l

Figure 3 is a plan view ofv a sewn article indieating two types of stitching;

Figure 4 is a longitudinal sectional detail taken at line 4-4 of Figure 3 on an enlarged scale;

Figure 5 is a plan view of one form of button sewn in place;

Figure 6 is a transverse section taken at line 6-6 of Figure 5, showing the button and material to which it is stitched;

lFigure 'l is a plan view showing another form of button; K

Figure 8 is a transverse section taken at line 8 8 of Figure 7, showing the stitching of Figure 7; and p Figure ures 1, 2 and 4, showing a modified form of construction in which the cement itself forms the attaching means.

Like parts are indicated by like numerals throughout the specication and drawing.

As shown in Figures 1 and 2, the device might 9 is a section generally similar to Figbe considered as a quilt. It is formed in general ofrelatively loosely compacted material i to one or both faces of which may be applied al sheet of material 2, 2. In another application oi'the invention this may be cloth, paper o r d' their equivalents, while the material l might be f wool, hair, cotton batting, kapok or their equivalents. f

In the form oi Figure i, the parts are sewn together by threads S, t, which interlock as at il. m It will be' understood that when the needle is forced through the fabric holes are formed and into these holes the thread is pulled. The scale and proportions of Figures 1 and 2 have been exaggerated to illustrate this effect.

During the process of stitching or sewing, cement, preferably water proof and of any desired nature, is applied to the thread. It may be applied by the machine at any stage during the passage of the thread through the machine or it might be applied before the thread reaches the machine or after it leaves'the machine, so long as the cement remains plastic until the time when the thread is sewn or stitched into the fabric. After .the thread has been stitched 55 into the fabric to form, for example, the articles of Figures 1 and 2, the cement'hardens. Hardened cement is shown as at E, iilling the unoccupied parts of the perforations or depressions formed -by the stitching operation. This cement not only lls these depressions or perorations but also coats, and it'may be in cases 'impregnates, the thread itself, .thus cementing the threads to each other where they cross or con- .tact each other, and thus lcementingV together the parts or knots of thread if any are made during the stitching. To some degree the cement permeates the material i as indicated in Figures 1 and 2 by the numeral- 6. The cement also m causes the threads to adhere to the material 2 where the thread contacts the material, for example, through the area or distance 1. 'I'o some degree also the cement maypermeate the fabric 2 as at 8. In general the result of the method 5 by means of which the article shown in Figures 1 and 2 is produced, is that the threads are cemented to the fabric wherever theycontact it, the threads are cemented to each other wher'- ever they contact each other and the perfora- 50 tions or depressions formed by the stitching opy eration are filled with the cement and thus the several component parts of the nal articleare cemented together. The structure or ,article is increased in strength and the threads and the 55 Fig. 3 serving to secure'the border or binding 2 adjacent portions of the article are made water proof,- where water proof cement is used.

Any kind of cement desired may be used and y the invention is not limited either as to the arti'- cle or the process disclosed to the use of any particular cement and the word cemen is to be understood broadly as meaning an adhesive, whether or not it is water proof. For general purposes it is preferable that a water proof cement is used. For certain classesv of article which 'are to be washed or subjected to moisture, water proof cement will always be used. Where, however, the article is not to be subjected 4to ,moisture other forms of cementKmay be used. One important form of device \made by the method of this invention is that in which the article is to be used as heat insulation, for example, in refrigerators or otherwise, and for that usev asphalt cement is particularly adaptable though other cements may be used. Where it is to be subjected to heat, a cement which vulcanizes or undergoesother definite chemical and physical changes as the result of the application 'of heat may be used, and my invention contemplates the use of any and all types of cement or adhesives and not merely those enumerated above.

Theiform of the invention shown in Figure 2 is generally the` same as that of Figure 1 except that instead of the lock stitch shown in Figure l a-chain stitch is shown in which a thread 9 is' used, the threads crossing and contacting each other as at l0.

Figure 3 illustrates an article'in which the main body is indicated as at ii and a binding is has been applied. Two arrangements oistitching have been used. Thus an angular arrangement of stitches is accomplished by the thread or threads i3, the perforations or depressions being sealed by portions of cement E as in the case oi Figs. 1 and 2l, and the thread it is cemented to the surface of. the binding l2 as described in 'connection with Figs. 1 and 2 and illustrated in particular at l in those figures. In' addition a straight/line stitching i4 is shown in additionally to the body H. Here again cementing Voccurs as at 5 in the depressions or perforations and at other points where the thread contacts the surface or other parts of the article.

As illustrated in Figure e, the stitching of the threadd il is cemented generally in the same manner illustrated in detail and on a larger scale Figures 1 and 2.

Many articles such as buttons and theiriequivalents may be sewn in place to fabric oor other articles to which it is desired to attach such fastenings. Thus in Figure 5 a section of cloth I5 is shown which, as shown in Figure 6, may be double. comprising two thicmesses of cloth SB. :A button ihaving two perforations il is sewn to the cloth by `one or more threads i8. These threads are cemented together and to some degree the cement will ordinarily permeate the fabric i@ as shown at i9, thus cementing the threads to the fabric and if double thicknesses of fabric are used, cementing them to eachother'adjacent the periorations through which the threads pass.

A certain quantity oi the cement may also collect in the perforations il of the button as at 2li;

When this occurs the button is additionally cemented tothe threads and to some degree is cemented directly to the clo'th by cement which is carried through the perforations by the thread or otherwise. The composite. article thus includes a button, a support to which it is stitched.

and threads which engage both the button and the support and these parts are cemented to each other wholly or in part. In the main, of course, it is the threads which serve to hold the button to thesupport but .a certain amountl of direct cementing of the buttonto thev support may take place. The threads, if more than one is used, are cemented to each other and this gives the effect of a double or plural thread where more than'one is used, and the cementing of adjacent strands of thread occurs. f

As shown in Figures 7 and 8, the support I 5 appears again and a button 2i having four holes 22 is stitched to the support by threads 23. Cement 2l lls wholly or partially the perforations in the buttons. Figures 5and 6, cement carried by the threads 23 may permeate they member or members I5 as shown at 25, to cement the threads to the support members I5 and where more than one of these is used,'to cement them to each other.

'I'he sewing has been illustrated in chain stitch vand lock stitch and two diierent types of button sewing may be used. It is to. be understood that the invention is not limited in any wayto any particular type ofstitching either for fastening As in the case of the form of,

sheet members together or for fastening buttons y or their equivalents to supportingI parts. In general the method may be applied t'o any sewing or tacking operation, whether mechanical or by hand, `and the articles may be made by machine or by hand but iny each case the material with' which the stitches are made has applied to it a cement which remains suillciently soft until after the stitching material is in place so that itis carried in and thereafter hardens suiilciently to cement the stitching material to the article which -is stitched and to cement threads or the'liketo .each other and to the`-,material through which' wherever that contact occurs. y

Where in the claims and specification I have used the word thread I mean any thread or thread-like fastening member or its equivalent, which may be used in sewing or tacking. It might be a single strand or a cord of any material, wire, gut, or any other material of similar or analogous usefulness.

" 'In the modified form of Figure 9, two or more might be treated separately and the holes formedy and then perforated sheets associated together with the holes in register or sheets of material which is perforated in itself might be associated together with the holes in register d thev ceried out.- The4 holes are"indicated at 21 and they v may be formed inv any way, but one convenient .way is to form them by a needle or punch oper- .m they pass or with which they have any contact,

y inenting operation which is describe low carv ating in a punching,l sewing or tacking machine but without thread. The holes might, of course;

e be formed by hand or otherwise.- It is preferable as the holes are formed to ill them with cement. If a punching, sewing ortacking machine is used withl a punching, sewing or tacking needle but without thread, the cement is preferably applied to the needle during operation so that the needle 76 is constantly or periodically supplied with the cement and as the perforation is made or immediately thereafter, the cement is carried directly or flows into the perforation. Such cement is indicated at 28 in the two left hand perforations of Figure 9. As shown in those perforations the lcorners of the perforations are rounded as at 29.

'I'his may or may not occur, depending on the shape of the punching, sewing or tacking needle and upon other factors. The invention is not limited to a rounded perforation and the two v right hand perforations 30 of Figure 9 are shown the member which forms the perforation, al-` without such rounded or tapered ends. They are shown with cement 3| filling them. The cement ordinarily permeates the material around the perforation to some degree. This is indicated at 32 and 33 in the perforations 21 and 30, respectively. When the cement dries it forms in effect a cement f rivet, lling the perforations and in some cases penetrating into the material or between the sheets of material or between the fibers of the material and this cement or rubber rivet or its equivalent holds the sheets together without thread. It will ordinarily permeate the material and forms not merely a rivet but a joining means which engages the walls of he opening through the material. Ordinarily ere will be a certain amount of overflow or spr ading of the cement plug or rivet as indicated at 34 and 35 which fills the perforations 21 and 30, respectively.

` The device of Figure 9 is useful in many places and while it may have less structural strength than'that present in the devices in which threading or stitching material is used, for many purposes its structural strength is adequate and the method of producing it is in a sense broadly the same as the method of producing the other forms of the device, namely, the association together of sheets of material, forming perforations in them and filling those perforations with cement, glue or their equivalent, preferablyat the time that the perforation is made and preferably by means of though the cement might be otherwise introduced and at another time.

While only two sheets of material are shown as being fastened Atogether in Figure 9, almost any number might be fastened together and this is true also of the earlier shown forms of the device. The invention is not limited to the securing together of any particular number of parts or sheets of material.

In all of the forms of the invention it is to be understood that almost any fabric may be secured together. Woven cloth, felt, wadding, loose fiber or anything else which it is useful to secure together, may be secured by any of the means disclosed herewith.

While the form of Figure 9 has been described as having in effect a cement or rubber rivet, it is clearthat the cement 5 which fills the perforations in the earlier described forms of the invention also acts as a cement or rubber rivet or its equivalent and differs from the form of Figure 9 V mainly by the fact that in addition to the rubber rivet some form of thread or stitching is used. I-claim: l. The method of joining a plurality of sheets of fibrous textile material which includes positioning a plurality of suc-h sheets together for attachment by sewing, applying an unsolidied liquid Acement to a fibrous thread, drawing the!!l cemented thread through the sheets prior to the solidication of the applied liquid cement, and

thereby drawing said cement with the thread through the apertures formed in the course of the sewing operation andimpregnating not only l0 the thread but the adjacent portions of the sheets with said cement, all prior to the solidication of the cement.

2. The method of making a sewn and cemented article which includes placing a plurality of.

fibrous textile material at opposite sides of a loose fibrous filler, applying an unsolidifled liquid cement to a fibrous thread, drawing the cemented thread through the sheets and ller prior to the solidification of the applied liquid'cement, and thereby drawing said cement with the thread through the apertures formed in the course of the sewing operation and impregnating not only the thread but the adiacent portions of the sheets and filler with said cement, all prior to the solidiiication of the cement.
