UPHOLSTERY PIPING BAT AND METHOD OF MAKING THE SAME.

' Application filed March 16, 1925. Serial No. 16,079. i

To all whom) it may concern:

Be it known that I, MAURICE J. STAoK, a citizen of the United States, residing at Cohoes, in the county of Albany and Stateof New York, have invented certain new and useful Improvements in Upholstery Piping Bats and Methods of; .Maki 1g .the jsan'iey of I which the followingis aspecification.

The invention has for its object to provlde a new and improved construction of and method of manufacturing upholstery "piping batting foruse in upholstering auto'-.

mobile seat backs, cushions, quarter top pads and the like. i

In the now connnonly used methods of manufacturing such batting the same is" made in continuous lengths andof a width formed by folding a relatively wide sheet 'of batting upon. itself at successive inter-,

vals to provide the desired Width and thickness of said batting. To provide desired tensile strength in the batting. cores are laid into the central or other folds thereof. such cores consisting of continuous lengths of fabric or paper and when'theflatteris used,

it is usually gummed to hold it to position i and frequently to hold the folds of the bat together. 'The great'additional expense of manufacture occasioned by such use voi: :l.a.b-

Jric and paper cores and .;the.inconveniences and ineflicienciesof such 'vuse shouldbe readily apparent to those skilled inthe art Lin vwhich such battingis'used; A few of'the undesirablev features alluded to are here mentioned; First the cost of such materials and the labor and expenses incident to their purchase, storage and use: second, the waste occasioned by the necessity of throwing away sections of the batting which, by'

fault of machinery or human attention at an luterval 1n the process of its manufacture,

become unfit for commercial use, it being impractical to remove the cores from such sections and therefore necessary that the whole thereof, including the cotton batting proper which could otherwise be reworked and used, be thrown away: and third, the

impracticability of the most commonly used paper cores in that they utterly fail to ac-.

coinplish their intended purpose of roviding tensile strength to the batting an break from their secured points or some place throughout their length upon the first sudden shock in actual use. p

It is therefore. the object offimy present invention to. provide a .constructioneof. -.bat--F':'

ting and method of -.making the sarnein \vhicl1- ;the' {desired tensile strength is provided bv. use of'a core of the same material of which the batting is formed, not subject to readybreakage, in the manufacture of which it is unnecessary to employ any mahas taken place.

ment, ally of which will be first fullyu described in the following detailed description, then particularly pointed out in the appended. claims, reference being had to the accompanying drawings, iuwhich Figure. 1 is a diagrammatic plan view illustrating the mannerin which the batting sheeti istwist foldedat successive intervals .to form thecomplete continuous length of batt1ng,-the manner-of layingsin, the'ysoft rope core being also shown.

i The numeral 9 desi "ates the soft-r core of the batting whieh is made up of tin same cotton batting.i'n'ate'rial as is the sheeting' 1, which may inade mor or less stron according to how vti 'htly the same is twist-formed, and which hasthe quality of not'elongatin'g to any considerable degree 7 under stres es {Of 1156, thereby giving tensile strength to the, finished batting into the folds of which it. is laid and matted in the manner soon to be e iplained. V

In making up thebatting the soft-rope core 9 is laid such a distance from 'the edge of the cotton sheeting l vas to enable the After folder to twist-fold overtheshorterwidth to the side thereof as indicated in Figure 3 of the drawings. 1

gaa ssing the twist-folder. (it being un erstood that the Cotton sheeting is travell' in the direction .of the arrows on Figure 1 the folded parts are compressed by passing between rollers \2 or beneath roller 2 and over an immovable table as may be found convenient, in practice (it being understood that apparatus for manufaetu'ring this battiii" forms no part of my present invention); N i v erted by the roller or rollers 2 is such as e amo nt of eomprn ion en'- '0 reduce the thickness of the material to the desired degree before the second twist- 7 fold is made. 1 Having passed the roller or rollers 2 the material is 'v'en a secondtwish foldby the folder 6. he parts will then appear as illustrated inFigure 5, and after p'assin'gthrou'gh the second set of presser rolls 3 the part will appear as illustrated in Fired, p,

fter passing the secondset of rolls 3 the third and fourth twist-folds will-be imarted successively to the material by the olders and 8 respectively, the parts then appearingas illustrated in Figures 7 and 8 respectively, after which they will ass through the finalpr'esser (rolls 4 and the attin be compressed to its final condition as indlc'ated in Figurfe 9 and generally indicated in the drawings by the numeral 10.

As beforews'tatfed tn-seem 9 is in the nature of a soft-rope termed of the same cotton battin material of which the batting sheet is ormed and the strength of the same maybe varied Ia'c'co'rdin to how tightly the material from which 1t is formed is twistedto make the same. a a y I I prefer to. use a twist-formed eore rather than a soft rope of the plaited type'for a purpose soon to b'e ezliplained. By us ng such a hore I have found by aet'u'al test that the finished batting is much stron" er than that formed with paper cores and t e many disadvantages of cost, ready breakage, and rattling of l the batting so equipped is entirely eliminated. a

By usm'ga soft of the twisted type and laying that rope; with th direction of ts twist opposed to the directionof the first and the two successive twist-folds accomphshed by the folders 5', 6 and 7, as the, folds mentioned a're made inth'e direction indicated by the, arrows on Figure 3 the effect will be to jsoinewhatunw'r'ap the soft rope core with the double of facilitating the intermingling'and flattening out of the fibres of vthat rope and the causingof-the fibres thereof ,to become tightly enmeshed with those of the fold into which the rope is a laid. The effect ofthis function is so efiicient thatmueh reater tensile strength is given to thebattlngathanby the of paper cores and fibres become so enmeshed that the parts become substantially as one and r'norethan fill the need fora holding medium heretofore answered only by the more or less undesirable use of the gummed. feature in shell paper eore use. Should it become necessary 0 discard a portion of battin inade by my improved method becauseo .faultyhandhng or similar reasons, wasting of that portion is [unne ry as, o i i of th s ,bij i e i like material as the betting, the .whole theref be reworked and reused,

a Beetion of In igure of the drawings batting is illustrated with a section of softrope core projecting therefrom. In Figure 11 is illustrated substantially the manner in which the fibres of the core are unravelled and caused to flatten out and intermingle with the fibres of the fold into which the said core is laid.

As stated the use of such core provides batting of greater tensile strength, which is not open to the objections urged to the use of a gummed paper core, viz: occasioning complete wasteaof imperfect uncommercial sections, objectionable rattling and ready breakage under slight shock.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the noveldetails of construction, method of manufacturing and the advantages of my invention will be readily apparent to those skilled in the art to which it relates.

What I claim is: I

1. Cotton batting of the class descrlbed formed of successively folding a sheet of fibrous material and having a core of softrope of the twist-formed type laid in one fold thereof, the twist of said core being opposed to the direction in which said folds are'made.

2. The method of making cotton batting of the class described which consists in laying a core of soft-rope of the twist formed type upon a sheet of fibrous materlal and successively folding-that sheet to enfold said core and to provide the desired batting width, the twist of said core being opposed to the direction in which said folds are made to cause the same to be partially untwisted by'said folding action and the fibres of the same and those of the sheet being folded to enmesh.

3. The method of making cotton batting of the class described which consists in laying a core of soft-rope of the twist-formed type upon a sheet of fibrous material, the said sheet and the said core being of the same material, and successively foldingthatsheet to enfold said core and to provide the de sired batting width, the twist of said core being opposed to the direction in which said folds are made to cause the same to be parof the same kind and grade of material.

5. Themethod of making continuous bats which includes the steps of taking some bat material and twisting it into a rope, laying the rope on a batting strip and folding the strip over the rope as a core while permitting the rope to untwist more or less thereb to cause its fibres to rub and interlock with the fibres of the strip.

6. Themethod of making continuous bats which includes the steps of talking some oat material and twisting it into a re e laying the rope on a batting strip and f0 (1- a ing the 'strip over the rope as a core while permitting the rope to untwist more or less thereby to cause its fibres to rub and interlock with the fibres of. the strip, and applymg flattening pressure to the folded bat to flatten the core.

'7. A continuous bat with a core composed of the same material as the bat loosely twisted into the form of a rope and having its fibres interlocked with those of the bat proper. I

8. A bat reinforced by a core which has greater tensile strength than the bat, said core being composed of fibres adapted to mix with those of the bat, said fibres being so loosely interengaged with each other that they may be readily picked apart when the bat is reworked.

9. A cotton bat comprising a-body of batting material enclosing a softrope core of a material suitable to mix with the stock of the bat.

10. A cot on bat comprisin a body of bat material enclosing a core 0% soft loosely twisted rope of a material suitable 'tb mix with the stock of the bat.
