This .mvention relates to spools, particularly toin the textile industry. The methods of fabricate ing the-component elements of the spool aregsuch j that .theseelements may be made at'a minimum of expense and-may be assembled together to form the completed article with great ease and faci1ity.:-

Without departure from the spirit and 1 scope of the; invention, variousembodiments thereof maybefdevised, two of which are illustrated in the accompanying. drawin'gfand will be. hereinafter described in detail, by way of example.

'In the drawing: e Figure 1 is an axial section through a completed spool of the single headed type constructed in accordance with the invention; F Figure 2 is a plan view of the same and Figure 3 is an axial section through a modified type of spool. a i v The spool, in both of its forms, or' in still further forms which may be devised in accord-- ance with the invention to comply with the requirements of individual users, comprises essentially four elements, the barrel or central cylindrical member 10,.which is generally a tube of paper, wood, fiber, or'metal, a conical base member 11, an annular end disc 12, and a cylindrical spacing or abutment member 13. Preferably the conical member 11 or, more prop- 'erly, the frusto-conical member 11, is formed of thin metal as indicated in Figure 1, the annular end disc 12 of paper or fiber, and the spacing member 13 of the same material. It'will beunlast mentioned elements other materials may be employed if desired so long as these materials produce a resulting article having the necessary light weight, balance, rigidity, and ruggedness.

The end disc 12 is an annular member, the interior diameter of which is the. same as the exterior diameter of the tube or barrel 10, and the outer periphery of which is truly concentric PATENT. orn-cs with the peripher'yfof its central aperture. I

frusto-conical metallic base ,11 has. its circular edge closely embracing the exterior cylindrical surface. of theibarrel l0 and its lower margin curved around the outer edge. or. the end disc. 12 as shown. Thetubular. spacer 13.has,its ,outer' annular'edge surface disposed in a; plane transverse to the axis of the spool and resting against theadjacent parallel inner surface oftheend disc 12.. The opposite end of-member 13 is frustoconical and liesclosely against-the adjacent surfacegof the conicalbase 11; -It isthe function of: thespacing orabutment member 13, which is rigidly secured to the barrel 10, to firmly-support the upper margin of the conical base 11 against downwardjmovement (111811130. pressure of the thread package or winding which the spool supsembled in various'ways,.butfpreferably I first slidelthe'finembrdil ontothe barrel member 10 until it occupies'the positioni'n which it is shown in the drawing. It is "secured" in this position either by means ofjglue or 'adhe'sive, stitches of metalor fiberthread, rivets; or any other con end disc 12 against inward The several elements of 9 the spool may be as- J venient and inexpensive but nevertheless secure manner. The conical baseimember 11 is then slipped over the barrel and moved downwardly along the same until it contacts with the upper frusto-conical surface of the spacing member 13. The annular end disc 12 is then positioned as shown,'resti ng against the lower end of the brac- 7 it will be necessary to first slip over the barrel the conical member similar to the base 11 and to then add the spacing or abutment member 13 and finally the end disc 12, after the member 13 has been attached to the barrel'inproper position.

' ing member 13. Finally the lower outer margin rials, is illustrated in axial section. Here the barrel 20 is formed of a'material which permits it to be upset or turned over at its ends to form the end disc 22 being clamped or firmly retained,

between the outer end of this member and the.

looking shoulders, one of which is indicated'at 20'; Such a barrel may conveniently be formed of a paper sheet made into tubular form by winding upon a mandrel. The conical base 21 is nonmetallic, preferably being a base formed of compressed paper together with a binding material,

of Charles K. Dunlap. The member 23 may be formed of any suitable material, such, for in stance, asfpaper, and the end disc 22 may be conveniently fabricated of fiber. Member 23 is secured to the barrel in any well-knownmanner,

turned-over portion 20' of barrel 20. The outer periphery of the end disc 22 is beveled so as to fit snugly against the conical inner surface of base 21, and a suitablefadhesive is employed to secure these two surfaces firmly together. A suitable adhesive may also be employed tosecure the cylindrical inner edge surf-ace of base 21 'to the outer surface of barrel 20am! alsoto attach member 2l to member 23 where these two members contact with each other. In this form of the invention, where it is desired'to form a spool with two heads, similar parts are, applied to the opposite end of the barrel but in reverse order. The final operation of assembling this opposite end willbe, of course, the heading overof theopposite end of the'tubular barrel 2.0.

A spool constructed in accordance with this invention has at all times-perfect alignmentof tilting of these bases can occurrelatively to the axis of the barrel, and hence the angle of taper of all elements of the outer conical surfaces of the bases will remain constant throughout the life of the spool. Other forms of the invention may be devised by slightly modifying the details of construction of the spools disclosed byway of example or by the selection of somewhat different materials, 'dependingupon the uses to which the spool is'to be put. V Having thus described the invention, what, is claimed as new and desired to be secured by Letters Patent is: V V

1. In a spool, in combination, a cylindrical barrel, a spacing or abutment member encircling the barrel and secured thereto, an annular end disc also encircling the barrel, the inner margin of said disc abutting against the outer end of said member, and a frusto-conical base, the outer edge of which engages the outer periphery of said end disc and the inner periphery, of which contacts with the :barrel and the end of said member I 1 2. In a spool, in combination, a cylindrical barrel, 'a tubular' s pacing, or'abutment member enveloping the barrel and rigidly attachedthereto, an annular end disc encirclingthebarrel; the

inner margin of' said disc abuttingthe outer end of said member, and a frusto-conical base, the outermarginoi which engages and is secured to the outer periphery of 'said end'disc and the circular inner edge of which contacts with the barrel, theinnenmargin of said base resting upon the inner end of said member and being'supported thereby.

3; Ina spool, in combination, a cylindrical bar- 'rel, a'tubula'r spacing orabutment member enveloping the barrel at one end thereof and rigidly attached thereto, an annular end disc encircling the barrel, the innermargin of said disc abutting the outer end of said member, and afrustoconical metallic base comprising a sheet of thin ductile metal, the outer margin of which is curved around the'outer periphery of -said disc and: closely engages the same, and the circular innercedgeof which contacts with the barrel and the inner end of said member.

4. A spool comprising a barrel, an annularc end disc at the end thereof, a frusto-conical base, and

an abutment or spacing member affixed to the barrel, one endof said member supporting said end disc and the other end thereof supporting the innermargin of said base.
