United States Patent 3,195,939 ANCHORING MEANS FOR FLAT BANDS Roe Howe Lagarde, (Erhard, and Clarke Murphy, Jr., Baltimore, Md., assignors to E. W. Bliss Company, Canton, Ohio, a corporation of Delaware Filed Jan. 29, 1963, Ser. No. 254,788 Claims. (Cl. 287-82) The present invention relates to flat, woven, flexible bands, or webbing, and in particular to the end structure for holding the band in a suitable fixture. The band or web may be constructed from any suitable weavable material, such as, natural, synthetic, metal or glass fibers.

Heretofore it was most diflicult to hold the end of a band or webbing, particularly when the band was made from synthetic fibers and when the band was under a high degree of tensional strain. The primary object of the invention is to provide an improved lapped end structure for a band or the like wherein, the band may be attached to a more compact holding element.

Another object of the invention is to provide an improved lapped end structure for a band wherein, the end may be effectively held by a holding element of no greater width than the width of the band.

A further object of the invention is to provide a lap structure whereby the thickness of the band will be increasedand its width decreased adjacent the end of the band to permit its attachment to a greater variety of shapes of holding elements and at the same time increase the holding capacity of the holding element upon the band.

Astill further object of the invention is to provide an improved method of constructing the end of the band into a lug for holding the same within a holding element.

While several objects of the invention have been pointed out, other objects, uses and advantages will become more apparent as the nature of the invention is more fully disclosed, the same consists in its novel arrangement and forming of its several parts shown in the accompanying drawings forming a part of this specification, and in which:

FIGURE 14 is a sectional view taken along line 14-14 in FIGURE 13.

FIGURE 15 is an end view looking from right to left in FIGURE 13 showing both the outer end of the lug and the lug holding element.

In the description to follow, like character references are used in designating like and similar parts throughout the several views;

Throughout the several views the band, or web is generally designated by the letter A having

lateral edges

12 and 14. The band with longitudinal, or woof strands 21 and later a1, or weft strands 22;

Referring first to FIGURES 1 to 6 inclusive, the end of the band A is unbraided, or unwoven by removing the lateral, or weft strands 22 for a distance at least equal to one-third the width of the band. However, there is no limit to the length of the unbraided longitudinal strands 21' and if desired, may extend from the end of the woven portion outwardly to the outer end of the lug.

The woven portion immediately adjacent the unbraided strands 21 and designated by the numeral 24 is tightly lapped upon itself. (See FIGURES 1 and 2.) This reduces the width of the band and also reduces the width of the area to be occupied by the unwoven strands 21'. This lapping also increases the thickness of the band and the area to be occupied by the unbraided strands, which will hereinafter be referred to more in detail.

The lapped portion 24 is shown in FIGURE 2 to be wrapped about a core 26. This is desirable if the band is of such-thickness, or texture to resist bending it into a tight lap. If the band is pliable and will allow the band to be tightly rolled, or lapped and where there is no opening, or practically no opening between the laps, the core 26 may be dispensed with. The lapping of the band is substantially parallel with the longitudinal or woof strands 21. The unwoven longitudinal or woof strands 21' are extended outwardly from the woven folded portion 24 in a diverging flare, that is, the opening between the strands is greater as the distance from the woven lapped portion 24 increases, as shown in FIGURE 1.

These diverging strands 21' are either placed into a suitable mold, or a lug holding element or fixture designed to hold the lug, as shown at 28.

About the extended and flared unwoven strands 21' there is introduced preferably, a solidifiable liquid or semi-liquid substance, preferably an organic plastic type. However, other suitable substances may also be used, such as, cement, rubber, epoxy, etc. Nor is the substance to be limited to a solidifiable liquid or semi-liquid, but the substances may be of a granular nature, to which heat and pressure may be applied for solidification, or a solidifying agent may be added to the material within the mold or fixture as the case may be. This solidifiable substance is adapted to solidify into a solid, or semi-solid lug L, filling the spaces between the strands 21 and adhering tothe strands themselves to form a rigid, or semirigid mass.

The outer surface of this mass, or lug L will take the form of the mold (not shown) or, that the fixture 28, whichever the case may be. The preferred shape of the lug is in the form of a modified taper. The taper is shown as being in the form of a gradually concaved surface 30, beginning with a parallel side surface substantially at point B adjacent the smaller diameter, or

neck portion L' of the lug. he concaved portion 32 of the lug surface extends substantially between the points B and B. It has been found by experiment that the lug L will have an increasing holding capacity in relation tqits diameter if the lug is provided with a head L", such as shown extending between points B and C The thickness of the head L" has been found to give satisfactorysupport to the tapered portion L in preventing collapsing of the plugif it is at least one quarter the thickness'of the maximum diameterof the. upward portion of the lug.

The head L is shown with is not limited thereto. a

cylindricalsideiwall 30, but

7 It is of substantial advantage to have this particular V shaped lug formed with a relatively long concaved surface beginning inwardly upon the woven portion of the band and increasing the curvature of its surface as it approaches is of elliptical form in cross-section and is not provided Witha core element, as shown in FIGURE 5. In this form, the lateral edges .12 and 14 of the lapped portion I are shown in abutted relationship, similar ot that shown in FIGURE 5. The. band is lappedwherein the, central portion 33'-,of the band extends'across on'e of the longer sides of the ellipse and the side sections 33" and 33" extend along the opposite longer side of the ellipse and are abuttedadjacent the center of the side section. The lug is formed insubstantially the same manner as that described for the forrnshown in FIGURES 1 to 3. The fixture shown at39 is of substantially the same structure asthose previously described in FIGURES .1 to 3,except the portion engaging the lapped section 33 of the band the outer limits of the diverging portion of the lug. The a H r as round, square, etc. and having means associated thereinner surface-of the fixture, as stated hereinbeforepis of substantially the same shapeas the outer. surface of the lug and is provided with a portion extending from the points B to B of c'onvexedform to coincide'with the concaved surface of 'the lug. The remaining portion of the lug surface and inner wall of the fixture extending from the point B toward the lapped portion is parallel 1 with the longitudinal axis of the lug and band. By having the walls of the neck portions of the lug and fixture without a taper will reduce the compression in this area and allows the remainder of the concaved surface of the lug to progressively takeup the load. I

i This areaof no taper prevents or reduces a tendency to rupture the plug, .or to move out of alignment the unbraided strands ll'adjacent the woven lapped portion.

It has been found by experiment that when the band.

is formed from artificial organic plastic fibers,'-it is more desirable also to construct the lug of ,an organiepla'stic substance, and further, if the lug is compounded to offer some slight-elasticity, itwill aid in the holding powerof the lug, which allows a certain amount; of take-upin the unevenness of the strands 'within the lug. When the band is under heavy stress a slightly'elastic lug also mayexist between the lug and the fixtures.

As mentioned heretofore, the parallel neck portion of allows the lug to conform-to'jany slight irregularities that the ;lug and fixture will allow the longitudinal strands to remain firml-yengaged by the lug adjacent the neck portion before the gradual diverging lug increasing surfaces begin to pickup the load. This prevents: any disis of elliptical cross-sectional shape to correspond with the lapped band. However, the outer portions (not shown) of the fixture may take any; other conventional form, such with for fastening the same to a suitable support.

Other forms of 'lappingof a more compounded nature are shown in the remaining illustrations, However, certain parts, such as the band A, the unbraided strands 21', the concaved surface of the lug, the operation and general characteristics of the band, the lug and the fixtures are the sameas that previously'described in detail, in. FIGURES 1 to 3 and therefore, no detailed description of these parts is believed necessary to understand the structure, and operation of the forms next to be referred L. toonly where necessary to bring out the particular feaao;

tures of the form of lap. V

Referring to FIGURES 7 to 9 the fixture 31 is somewhat similar is the fixture 28 shown in FIGURES 1 m 3, but being squarein cross-section having cars 31" and '3 1"fthr ough which are

holes

36 and 36 for supporting the fixture to a support(not shown).. .However, as stated in regard to the fixture 28, the fixtures may be ofany convenient shape and may be provided withany suitable means'for. supporting the same to a support. Toconform wlth the square fixture, the lug would also be square, as shown in FIGURES 8 and 9. The lapped area 37 is folded in theform of a letter S. The lap comprises a 'centraliportion 38 and two .

side portions

39 and 40 lapped so that the lateral edges 12 and 14 of. the .band a are positioned in opposite directions and diagonal with respect to the lap. V

In FIGURES 10 and 12 there is shown a different type of lap; This type of lapis shown at 41 and is lapped tortion of the neck portion of the lug due to high com I pression on its side walls that might affect the adhesiveness of the lug to the strands 21' adjacent the lapped portion.

'The neck portion of the fixture is adapted to extend over at least a portion of the lapped area as shown at .24 in FIGURE 1 in order to give to the unbraided strands 21' a straight pull with the longitudinal axis of the band. The fixture 28' shown in FIGURES 1 to'3 is ofcircular form and is provided with extending-ears 28'. and 28"" having holes 34'and 34f*ex tending therethrough for re-.

ofmaterial to. which thesolidifiable massiwould adhere;

The core 26' is of such siz'e as to allow thelatera'l in the form of'the letter M. The lap portion of the band is best illustrated in FIGURE 11 and is provided with a: double central portion, as shown at; 42 and 44, and two side portions 46.and 48 respectively. The lateral edge 12 of the side portion 46 and the lateral edge 14 of theside portion 48 are extendedin the same direction. The fixture 56 is illustratedas being also square in crosssection as previously shown and described for -fixture'31 shown in the species illustrated in FIGURES 7 to 9, but likewise may. be of .any convenient shape. The-fixture I 536 is provided with ears 56' and 56 eXtendingoutwardly from the main portion of the fixture ,56 having hole 57 manner as,previous'ly' described for the foregoingspecies.

edges 12, and 14 of. the bandto abut, and while shown in cross-section :to be of circular shape, it may take any I desirable form, such as, square, rectangular, etc.- The lug would be formed in substantially the samen'ianner as previously described for FIGURES 1 t'oj3. The fixture 27 is. quitesimilar to the fixture 28 in substantially'the same ,way. 7

FIGURE 6 is still afurther variation and operates;

- A stillfurthen form-of lap is illustrated in FIGURES 13 to 15 .;.'This1form.is provided with a lap area 60 in which the central portion 62 ofithe band is of .arcuated fo'rmin cross-section (see FIGURE-14).: The outer por-.

tions of theband, as shown at 64 and, are turned inwardly alongathe lines 64';and 66, wherein the outer U j 7 side portions 64'and 66 of the band areadjacent each 7 from the, form; 'shownin FIGURES lto 3, in that, the lapped portion other having their

respective edges

12 and 14 abutting adjacent thecon caved' surface 62 of the ar'cuated portion 62. This type lap is very compact and is particularly adapted for bands of such thickness and width and of such texture as to permit the band to be folded in this particular manner. In this form, the fixture '70 is shown in circular cross-section form, as previously described in FIGURES 1 to 3. The fixture 70 is provided with extended ears 72 and 72

' having openings

73 and 73 therethrough for receiving a pin (not shown) for fastening the fixture to a support (not shown), however, any suitable holding means may be substituted therefor.

The fixtures regardless of the type of lap may be of most any cross-sectional shape, or combination of these shapes, depending upon the circumstances and feasibility in manufacturing.

While a particular type of lap is shown in FIGURES 7 to 9 and in FIGURES 10 to 12, these laps may be folded in multiples of these forms, provided the band is of a suitable texture and of suitable width and thickness to permit such a fold.

The fixtures regardless of the type of lap are designed to hold and may be of most any cross-sectional shape, or combination of shapes. The fixtures may be made of any suitable material, however, it is preferable to use a strong non-corrosive metal such as stainless steel. It is also not necessary to have the fixtures constructed of a single piece. If the lug L is formed in a separate mold, the fixture may be longitudinally split, so that, it may be readily attached to the lug. In this way the fixture may then be attached to the band at the time it is to be used.

By the use of the present end holding structure, bands and/or webbing having great potential strength may be effectively used in places and for purposes where hereinbefore their use was hampered because of the holding qualities, bulkiness and inappropriate shape of the fixtures and in which the fixtures themselves had a tendency to break the strands of the band long before the tensile strength of the band was reached.

The neck of the lug and the lapped portion of the band are snugly engaged by the neck, or small end of the fixture opening for holding the lapped portion in its designed pattern. This, as has been stated before, keeps the longitudinal strands, which are embedded in the lug, parallel with the axis of the band until they are well extended into the woven portion of the band.

While the invention has been illustrated in several forms, it will be understood that various changes may be made in the detail arrangements and proportions of the parts without departing from the scope of the claims.

We claim:
