a corporation or New Jersey I Application October 7, 1932, Serial No. 636,658 I 2 Claims; (01. 1242-119) f- This invention relates to reels such as are used for supporting cords and particularly cords com; posed of twisted paper strips.

Twisted paper cord and vegetable parchment twisted cord such as is described in my companion application Serial No. 636,659, filed October 7, 1932, are usually made on machines of which the one known in the trade as the Watson ma chine is a typical example. In such a machine the paper strips are twisted into the cord formation and are wound on a large spool. From this large spool the cord is generally unwound into balls of cord whereupon the large spool is.

replaced in the twisting machine whenever. said 1 machine is ready for the installation of another spool. These spools are very substantial and expensive and remain in effect a part of thetwisting machine. Rewinding, of course, involvesmachinery and labor. Under. theseconditions it oocurred to me to investigate whether it might not be possible to create a reel of great cheapness, yet sufficiently rugged to properly position and hold the cord in placeas it was manufactured by the twisting machine so that it might be possible to send the filled, reel directly to the customer without any rewinding, the customer throwing away the reel whenthe. cord has all been unwound therefrom. I have found that, within. the

limits imposed bythe problem, it wouldbe pos-- sible to accomplishsucha result andlthe reel which is the result, is-the subject matter of this application.

The reel is illustrated in the accompanying drawing, in which Fig. l is a side view partly in section; Fig. 2 is a cross section on the line 22 of Fig. 1; Fig. 3 is an end view of the spool; and Fig. 4 is a detail view of a modification.

In the drawing A designates two end flanges or discs of the reel composed of heavy cardboard or pressed wood, each provided with a central opening to receive and seat the metal collar B, B.

The collar B, B is constituted of a thin strip of bendable tin or of equivalent metal said strip being bent around the'end of the core C and positioned, in the finished reel, in tubular form in the apertures of each of the end discs A.- The tin strip is provided with a flange portion B parallel with the exterior faces of the discs A abutting against said flanges and. overlying the edges of the apertures of the said discs A, while the tubular part B which has a minimum width which is considerably greater than the thickness of the discs A and may be greater than several thicknesses of such discs, hugs the inner periphery of the apertures of the discs A and lines the inner peripheryof said apertures. A cardboard tube or core C fofappropriate thickness and length is supported in close contact with the inner periphery of the tubular metal section 13" having an outside diameter approximately the same as the diameter of the apertures of the discs A, so that when the parts are assembled they are all jammed tightly together. The tin sleeves B are prickpunched or in part depressed into the body of the material constituting the core C at several points as indicated at D to hold the several parts in place against axial displacement of the sleeves or outward displacement of the discs A, at least during the time that the core is wound on the reel in. the ,twisting machine. It is preferred 79 that one of the prick-punches, D shall be made at the point where as indicated in Fig, 1 the end edges of the tin sleeves B meet or where they may slightly overlap. Instead of prick-punching the tin sleeve B may be grooved as indicated at D in Fig. .4. The inner edge of the tubular metal section B' may also be-initially bent slightly in a directiontoward the tube C so as, as indicated at B. in Fig. 4,,to secure additional anchorage between ,the sleeve B and the tube C when the 8 partsare finally assembled.

'I'hefirst round of cord holds the tin collar in place so that-itis thereafter impossible for the collar or theends of the reel to come off the core ortube in the process of winding or of handlingthereel a fter i has been filled. Twisted paper cord is made and wound on spools or reels at a time when the paper as such is not free from moisture, but though the paper be quite wet, the strength of the new reel is such as to maintain its structure notwithstanding the strains which the presence of moisture and subsequent evaporation entails.

A twisting machine is generally provided with driving mechanism for rotating the reel at a rate corresponding to the rate of formation of the twisted cord. Such mechanism contacts with the inner surface of the spool and in the case of the new reel with the inner surface of the core or tube 0 near the ends of the spool. 1'00 The prick-punching and grooving of the metal sleeve B should therefore be limited so as not to have the metal of the sleeve passthrough the tube wall so as to interfere with the proper positioning of the driving elements of the ma-v chine. When a reel such as has been described has been filled on the twisting machine it is removed therefrom and replaced by another reel of the same character. Reels so filled are shipped I directly to the consumer, who, mounting them 1'10 to fit any of the standard twisting machines and may be made in larger or smaller sizes appropriate to the arts in which paper cord is used.

The manufacture of such reels is exceedingly simple and inexpensive. The simple and inexpensive character of the reel makes it possible to market the product without rewindingvv and also supplies the consumer with a more convenient and attractive support for his supply of, paper cord than he has thus far been able to obtain. v

I claim:

disc aperture and thecore having unconnected ends extending around the core in the form of a sleeve, having portions thereof depressedinto the body of the core to resist axial movement of the sleeve relating to said core, said sleeves having outwardly flaring end flanges adjacent to and encircling the ends of the core, the outer circumferential surface of said sleeves being parallel with the outer surface of the core and with the walls of the disc apertures, and the diameter of the disc apertures being approxi mately the same as the outside diameter of the sleeved core so that the discs if moved from one end of the reel to the other will encounter no obstruction'save the end flanges, said centrally apertured end discs being positioned on said sleeves adjacent to said flanges and held inposition at right angles to the axisof the core by the parallelism of the walls of the apertures and the circumferential surfaces of themetal sleeves and by the abutment of the side walls of the discs against the flanges of the sleeves, 'eachof said sleeves being considerably greater in width than the thickness of the end discs and extending into the path of the cord to be wound on the reel so that the cord when wound'on the core and upon the sleeves will tightly hold the sleeves in position on the core and the sleev es" thus held will, in coordinationwith the "cord wound on the reel, effectivelyprevent all relative 1 of a sleeve,"said sleeves" having outwardly flaring end flanges adjacent to-and encircling the ends 1. A reel for cord, comprising a heavy tubular paper core, a centrally apertured end disc ateach end of the core, the walls of the apertures of the discs being parallel with the outer sur-'" face of the core, and a thin pliable metallic strip intermediately situated between the wall of each ,of the core, and a thin pliable metallic strip intermediately situated between the wall of each .1 disc aperture and the core, having unconnected ends and extending around the core in the form of the'core, the outer circumferential surface face of the core and with the walls of the disc apertures and the diameter of the disc apertures being. approximately the same as the outside diameter of the sleeved core so that the discs if moved from one end of the reel toithe other will encounter no obstruction save the end flanges, said centrally apertured end discs being positioned on said sleeves adjacent to said flanges and held in position at right angles to the axis of the core by the parallelism of the walls of the apertures and the circumferential surfaces. of the metal'sleeves and by the abutment of the side walls of the discs against the flanges of the sleeves, each of said sleeves being in part depressed into the material constituting the core to resist axial movement of the sleeve relatively to the core, one portion at least of said depressed portions occurring at the meeting end parts of the strips of which the sleeves are formed, and each of said sleeves being considerably greater in width than the thickness of the end discs and extending into the path of the cord to be wound on the reel so that the cord when wound on the core and upon the sleeves will securely fasten the sleeves in position on the core and the sleeves thus heldwill, in coordination with the cord wound on the reel, effectively prevent all rela- 12c tive movementas between the core, the sleeves and the end discs, and will cause the end discs to be held on the core so that they can no longer be movedinwardlyon' the core or be separated therefromduring the withdrawal of cord from 5 the'reel inthe use of the reel.
