United States Patent O strands, and the like, hereinafter referred to as horse hair or bunch of hair.

In processing horse hair for sale to brush manufacturers and the like, it is necessary to clean and comb the horse hair prior to forming same into bundles. ln forming the bundles of horse hair, it has heretofore been the practice to arrange the strands in parallelism and to tie the bundle of strands at spaced intervals throughout its length by means of cord or twine, as illustrated in Fig. 4 in the accompanying drawing. After receiving a bundle of horse hair tied in the manner thus described, it was necessary for a brush manufacturer to untie the cords from the bundle, then dry the strands of horse hair Within suitable ovens to remove the moisture therefrom, and then to comb the hair. These operations were necessary to remove the waves from the hair caused by the old method of tying the bunches of hair at spaced intervals by means of cord or twine. lt will alsobe appreciated that a considerable amount of time and expense was involved in tying the bundles of horse hair for shipment to brush manufacturers.

It is an object of the present invention to provide a packaged bunch of natural or artificial strands such as horse hair in which the strands are arranged and maintained in straight parallel relation, free of objectionable waves, to thus effect a material saving to brush manufacturers, and the like, by eliminating subsequent processing operations, such as drying and combing which have heretofore been employed to remove the waves from the horse hair. 4

It is a further object of this invention Ato reduce the cost of packaging a bunch of hair by providing a flexible sleeve wrapper for the bunch of hair in place of the cord binding heretofore employed.

It is a further object of this invention to provide a sleeve wrapper formed of paper, thermoplastic tubing, or other suitable material to snugly enclose a cylindrical bunch of hair, the sleeve being preferably coextensive in length with the bunch of hair.

This invention further contemplates the provision of a novel apparatus for applying a flexible sleeve over a bunch of hair to enclose and protect same for storage or shipment to the point of use. Briefly, the apparatus comprises arcd depending from a ceiling or other structure and having a hook on its lower end for detachable engagementwith a depending bunch of hair, the rod being provided with a sleeve opening structure to engage the inner wall of'a paper tubing which is adapted to be guided downwardly over the bunch of hair by means of a guide sleeve.

2,741,884 Patented Apr. 17, 1956 ICC This invention further contemplates the provision of a novel method for packaging a bunch of horse hair.

This invention embodies other novel features, details of construction and arrangement of parts which are hereinafter set forth in the specification and claims, and illustrated in the accompanying drawing, wherein:

Fig. l is a side elevational view, partly in cross-section, illustrating a packaging apparatus embodying features of the present invention, the tubular paper wrapper and guide sleeve being shown in position above the bunch of hair at the beginning of the packaging operation.

Fig. 2 is a side elevational view, partly in cross-section, illustrating the manner in which the tubular paper wrapper is sleeved over the bunch of hair.

Fig. 3 is a detail perspective view illustrating a bunch of hair enclosed within the tubular wrapper.

Fig. 4 is a plan view illustrating a bunch of hair tied l at spaced intervals by means of cord or twine.

Referring now to the drawing, Fig. 4 illustrates the manner in which a bunch of hair 6 has heretofore been tied at spaced intervals by means of twine or cord 7 for storage or shipment to the point of use, such as the plant of a brush manufacturer. lt will be noted that the cords 7 act to impart waves to the strands of hair and that it has heretofore been necessary for brush manufacturers to remove these waves from the hair by means of drying and combing operations prior to insertion of the hair into brush backs.

The present invention contemplates the provision of a package of horse hair, as illustrated in Fig. 3, comprising a cylindrical bunch of hair 8 in which the strands are coexterlsive in length and arranged in parallelism within a tubular wrapper 9 having a length equal to the length of the bunch of hair. It is apparent that the wrapper 9 may be formed from any suitable material7 such as paper, thermoplastic tubing, or the like, whereby the package of horse hair may be cut into parts of predetermined length at the point of use. For example, the package of horse hair may `have an over-all length of from 5 to 40 inches, and the package may be cut transversely into desired lengths by brush manufacturers for use inmaking brushes.

The apparatus for applying the tubular wrapper 9 to a bunch of hair 8 is shown as comprising a rod l@ secured to, and depending from, a ceiling of a room or othersupporting structure. An eyelet screw 11 is threaded into or otherwise secured tothe lower end of the rod to engage the loop portions 12 of a pair of hooks lli- 13. A wrapper opening structure 14 is mounted in fixed position upon the lower end of the rod 10, the lower end of the member being formed with an upwardly diverging frustro-conical surface 1S and the upper end of the member being formed with a downwardly diverging frustroconical surface 16. The member 14 may be formed from any suitable material, but is preferably formed from rubber or cardboard and having a medial circumference at 17 substantially corresponding to the inner circumference of the wrapper 9. As the wrappers may vary slightly in circumference, it is desirable to form the member 14 of material, such as resilient rubber to accommodate the slight differences in circumference of the wrappers.

One end of a bunch of hair 8 is tightly embraced by a loop member 18 which is preferably formed of string or cord, the loop member being engaged at diametrieally opposed portions by means of the hooks 11i-t3 to support the bunch of hair in substantially coaxial alignment with the rod 10. A tubular frustro-conical guide member 19 is employed to guide the tubular Wrapper over the bunch of hair 8, the guide member being preferably formed of semi-rigid material, such as cardboard, rubber or thermoplastic.

In applying a tubular'wrapper '9 to a bunch of hair 8, the wrapper is ktlrst sleeved lupwardlyover 'the lower end of the rod and is adapted to be frictionally engaged by the opening member 14. The opener 14 thus holds the wrapper in fixed position while the loperator vsleeves the guide 19 over the lower end ofthe rod and engages the hooks 13 with the band ,18, as illustrated in Fig. l. The operator then inserts the small diameter end ofthe guide into the lower end of the wrapper 9 and then manually moves the guide 19 and wrapper 9 downwardly over the bunch of hair 8, as illustrated in Fig. 2. it will thus be noted that tbe guide ,19 serves to guide the lower marginal edge of the wrapper over ,theadjacent edge of the bunch of hair and thereafter acts to compress the bunch ofhair duringmovement .of the wrapper over same. When the endsof the wrapperare disposed adjacent `the ends of the bunch of hair, the packaged bunch of hair is disconnected from the `hooks 13-,13 .by severing the band 18 by means of a knife. After the bunch of khair 8 has beenpackaged within the tubular wrapper 9 for shipment or storage,-it will be noted that thestrands of hair are maintained in parallelism and are free from objectionable wavyformations. The wrappers 9 are substantially coextensive `in length with the bunch l.of hair .8 enclosed thereinto thus protect the hair from contact .or com tamination with foreign matter during shipment or storage. By means of the apparatus and method .employed in packaging a` bunch of hair 8, it will be noted that the bunch of hair is compressed within a Wrapper 9 which musty havesufcient tensile strength lto resist ybursting during shipment or ,storn age of the package.

While this invention yhasbeenshown inbut one form, it is obvious to those skilled in the artthat it is not y so limited, but is susceptible of various changes and modilications without departing from the spirit andgscope of the claimed invention.

Preferably, theflexible tubular ywrapper 9` is moisture and `vapor resistant to retard or Aprevent the infiltration of moisture into the bodyof horse hair enclosed in the wrapper.

Another advantage of the `invention resides inthe fact that the user cutting the package ,into parts or sections of predetermined length merely cuts through the Wrapper package, thus retaining the cut'nnit -within the wrapper. This severed unit may be handled with ease and the wrapper may be removed therefrom, subsequently yin the manufacturing operation.
