METHOD OF MAKING A TYING AND FASTENING DEVICE Filed Sept. 16, 1953 Eyf I INVENTOR. flawnaw l4! Evie/Jon United States Patent A METHOD MAKING AT'ITYING AND FASTENING. DEVICE.

Herman W. Patterson, O'verlandPark, Kans. Application September16, 1953,.SerialNo. 380,449 4 Claims. or; 154-116 This invention relates to new-and"useful 'improvements in tying and fastening devices and methods'of making the same, and relates-particularlyto tying and fastening devices of the type comprising an elongated endless'band'of elastic material having an enlarged head" at one end thereof adapted to be pulledthrough and secured intne loop at the opposite end of theba-nd after said band' has been wrapped about an object or objects'to'be secured.

The primary object of the present invention is' the provision, in a device of the character described, of a head so formed as to lock itself securely in the loop portion of the band.

A further object is the provision of a device of the character described wherein the head is, for purposes of economy, formed integrally with or'of'the same'material as the band, and" whichis planar aud disposed in the plane of the band, but which nevertheless, havingbeen inacter described wherein the head'is'composed of relatively I movable parts which are operable by the tension of; the band when in its operative position-to" grip the, lo'opfp'ortion' of theband, wherebysaid' head is"further*secured in theloop.

Still another object isthe' provision: of a method" for producing a fastening device of the character? described from a' strip offiatrubber stock.

A still further object is the provision of a method whereby the head, although integral with or formed of hte same material as the band, is rendered stiffer and more rigid than the band, whereby the head is rendered less likely to pull through the loop of the band.

With these objects in view, as well as other objects which will appear in the course of the specification, ref erence will be had to the drawing, wherein:

Fig. 1 is a front elevational view of a tying and fastening device embodying the present invention.

Fig. 2 is an edge View of the device as shown in Fig. 1.

Fig. 3 is a perspective view of the device shown in Figs. 1 and 2, shown arranged in operative position with the head inserted through the loop.

Figs. 4 and 5 are views similar to Fig. 1, showing two modified forms of the device.

Fig. 6 is an enlarged fragmentary view similar to Fig.

1, showing the head portion of still another modified form of the structure.

Fig. 7 is a view showing in operative engagement the head and loop portions of the device shown in Fig. 6.

Fig. 8 is a view similar to Fig. 6 showing still another modified form of the structure.

Like reference numerals apply to similar parts throughout the several views, and the numeral 2 designates a narrow strip of rubber or other elastic material arranged to form an endless elongated ring or band, said strip being folded at one end of the band to form what will hereinafter be designated loop 4, and the opposite reaches 2,,51ZAZ3 Patented Dec. 15, 1959 df the strip being brought into approximately parallel relation-ata point spaced apart from the loop and secured together.

Referring firstto Figs. 1 to' 3, thestripsr are cemented or otherwise secured at 6. The head 8 comprises a pair of flat," substantially circular knobs 10 disposed in the plane of the band and respectively at opposite sides of the connection 6. As shown said knobs are formed by extensions of the; endsof' strip 2 beyond connections 6, said extensions being rolled into tight spirals, said spirals being secured by vulcanization or introducing a layer of cement or the like between the convolutions thereof.

For a purpose hereinafter appearing, it is desirable also thatthe connection dand the securingmeans in the spirals be such as to render the knobs harder, stifier, and morev rigid than the remainder "of the band; This-may be done, in the case of vulcanization, by'applying a vulcanizing agent such' as sulphur to the surfacesto be joined before'the heat and-pressure is applied, or by using a hardening cement,. or otherwise. The dveice may advant'ageously be formed by first rolling the longitudinal edge'portions of" a flat rubber strip to produce the knobs, thenfb'lding the strip longitudinally to bring the knobs into substantially tangential relationship, making the connection g and, then'severing the resulting tubular member'ihto' the desired short? lengths.

The knobs 10'; being substantially circular, provide a V'-no'tch'12 between eacl'rknob and the adjacent reach of strip"- forming; loop. 4', said notches opening toward 100 4.:

'ln usejthe liandis wrapped, for example, about a bunch of vegetables to be secured together, in the general form shown in Fig. 3 and the head 8 is pulled through loop 4, the knobs 10 of the head being arranged respectively outside the opposite reaches of strip 2 forming said loop, as shown. In this position, the head is securely anchored in the loop, and will not pull out. The opposite reaches of the loop are engaged in notches 12. This prevents the head from turning into theplane of. the opening of the loop, in which position,:it could conceivably pull out of the loop accidentally. The hardening orStifienirig of the head as'described above serves to reduce deformation of the head by the pressure exerted thereinby loop 4; and hence to reduce still further any possibility that it will pull through the loop.

The modified structure shown in Fig. 4 is substantially similar to that shown in Figs. 1 to 3 except that the knobs of the head 8 are formed by a pair of flat circular discs 14 of rubber or the like, the extended end portions 16 of strip 2 being wrapped part way around the peripheral edges of said discs and secured thereto by vulcaniza- I that of the Fig. 1 species.

In the modification shown in Fig. 5, the end portions of strip 2 are parallel and lie together, being cemented or vulcanized along line 18. The flat rubber members 20 forming the knobs are each provided with a straight edge, said straight edges being vulcanized or cemented to the opposite sides of the joined portions of strip 2, along lines 22, and having curved edge portions forming V- notches 12 in conjunction with the adjacent portion of loop 4. The operation of this species is substantially the same as those previously described, except that the connection of the knob members 20 to the strip 2 along relatively extended lines renders less likely the possibility that the knobs will roll together upwardly, or away from their point of connection with the loop 4, under the pressure exerted thereon by the loop during use. It is hence less necessary with this species to use means as described a,b17,42a

above for stiffening or hardening the knobs, although such means may be used if desired.

t will be understood that in the species shown in both Fig. 4 and Fig; 5, the added knob members 14 and 20 may be of a material initially harder and stiffer than strip 2 if a stiffer head is desired. However, joining the knobs to strip 2 by the stifieningmethod already de scribed supplies stiffness along the lines subjected to main stresses during actual use, and will be sufficient in most cases. It will be apparent also that the species of Fig. 4 and Fig. 5 are adapted to be produced by a process utilizing a continuous fiat strip of rubber, the members 14 or 20 being secured to the strip in the form of a continuous cord before being severed into lengths equal to the thickness-of the finished band.

The modification shown in Figs. 6 and 7 is substantially the same as that of Fig. 1, except that the portions of strip my product and process, it is apparent that other minor changes could be made without departing from the spirit of the invention, and I therefore reserve rights to all such modifications or alterations as fall properly within the scope of the appended claims.

What I claim as new and desire to protect by Letters Patent is: 1

1. The process of producing a tying and fastening device comprising securing an enlarged, rubber cord along each longitudinal edge of a fiat rubber strip, folding said strip longitudinally to bring said cords into juxtaposition on the outside of the tubular member produced by said 4 strip, joining the edges of said strip along a line between 2 forming the outer convolutions of knobs 10, instead of being cemented or vulcanized directly together as at 6 in Fig. 1 are joined respectively to the opposite faces of a small rubber block 24 along the lines 26. Thus when the head 8 is passed through the loop 4, the opposite reaches of said loop adjacent the head will be forced together just beneath block 24. This, as shown in Fig. 7, rolls the knobs downwardly or toward the immediately adjacent portions of loop 4, thereby closing the V-notches 12 to grip the loop 4 therein. This serves as a means for further securing the head against accidental disengagement from the loop. This species is otherwise the same in construction and operation as the Fig. 1 species, and it may be fabricated by the same process, with of course the modification that the block 24 is then added in the form of a rubber strip or bar between the rolled edge portions 28, corresponding to block 24 in Figs. 6 and 7, is shaped 3 to conform to the contour of the spiral knobs 10 around approximately 90 degrees of their circumference, whereby to provide support for knobs 10 against outward movement when pressure is exerted thereon by loop 4, as-,de-

scribed in connection with the Fig. 5 species. Also, block 28 is provided with an outwardly extending tab 30 which serves as a convenient finger grip for pulling the head through the loop. I

While I have shown and described spec fic examples of said cords, and'severing the resulting tubular structure into short lengths.

2. The process as set forth inclaim 1 wherein the joining of said cords to said strip, and the joining of the edge portions of said strip, are accomplished by vulcanization in the presence of a rubber hardening agent, whereby the zones 'of juncture are rendered relatively stiff and hard as compared to the remaining portions of said cords.

3. The process as enumerated in claim 1 wherein said cords are formed by rolling the longitudinal edge portions of the rubber strip in spiral forms, said spiral forms being secured by vulcanization.

4. The process as set forth in claim 1 wherein the cords are formed by rolling the longitudinal edge portions of the rubber strip in spiral form and secured in rolled form by vulcanization after adding between the convolutions thereof a rubber hardening agent.
