FERDINAND B. BUEDINGEN, OF ROCHESTER, `NEW YORK.

SPOOL.

SPECIFICATION forming part of Letters Patent No. 668,973, dated February 26, 1901.

Application led January 2'7, 1900. Serial No. 3,010. (No model.)

To @ZZ 1071/0711/ it may concern:

Be it known that I, FERDINAND B. BUE- DINGEN,of Rochester', in the county of Monroe and State of New York, have invented certain new and usefulImprovements in Spools; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its object to provide a spool or reel adapted to contain ribbon, trimming, or similar material and that shall be light, simple, and consist of few parts, all of which may be easily and cheaply construeted.

To these ends my invention consists in certain improvements in construction and combinations of parts, all as will be clearly described, and the novel features point-ed out in the claims at the end of this specification.

In the drawings, Figure l is a perspective view of a spool constructed in accordance with my invention; Fig. 2, a longitudinal sectional View thereof.

Similar reference-numerals in both figures indicate similar parts.

In constructing spools according to my invention I employ a hollow central hub or spindle l, formed, preferably, of a continuous strip of fiexible material, such as paper or cardboard, formed or rolled about a mandrel, the successive layers, if more than one be employed, being glued or pasted to secure the parts and afford stability, making the tube of material. The tubes may be formed or cut strong and rigid with the minimum amount to the desired length, and in each of the ends I secure a metallic bushing consisting of the annular collar 2, strengthened upon its inner end by the inwardly-extending liange 3 and upon its outer end by thebroad radially-extending flange e, which projects outwardly, covering the end of the tube and affording a backing or support for the disks forming the ends of the spool. These bushings are secured in place by projections extending from the interior of the collar, forming points 5 of' metal, which are sunk into the material upon the inner side of the tube, securely engaging the latter and preventing a separation of the parts. The ends 6 of the spool are disks, as shown, and are adapted to be formed of a single piece of light stiff material, such as card board, and are provided at their centers with an aperture, through which the locking member extends. The latter is cup-shaped in form, consisting of a single piece of sheet metal embodying the annular collar 7, having the bottom 8 and the radially-extending liange 9. The collars 7 are adapted to project through the central aperturesin the end disks 6 and are formed slightly larger in diameter than the internal diameter of the collar 2 of the bushing, so that'as the former is compressed within the latter the collars will frictionally engage, holding the parts tightly together, with the end disks supported on the ends of the tubes between the flanges 4 and 9. The bottoms 8 of the locking members are provided with central apertures l0, the edges of which are curved or rounded, as shown, at'- fording a smooth bearing, whereby the spool may be supported either by inserting the fingers in the apertures or mounting it upon a suitable spindle.

2O indicates a bindingstrip, preferably formed of' metal and applied to the periphery of the end disks of the spool, and by forming or molding the edges of the strip over the edges of the disks and embedding it in the material, as shown, I am enabled to provide an edge which will not be dented or otherwise injured by rough handling and one which is smooth and not liable to injure a delicate fabric.

Spools or reels constructed in the manner I have described may be made in various sizes and adapted for holding different classes of goods, and by reason of the fact that there are no sharp corners or rough edges on my device it is particularly adapted for holding ribbon, trimming, or fine delicate fabric, such as lace. The end disks being secured to the hollow tube between the inner and outer flanges on the frictionally-engaging collars enables me to unite the parts rigidly without the use of glue or cement. The fastening devices are simple and easily constructed from IOO thin sheet metal, and when in operative position also serve to strengthen the tube or spindle.

I claim as my inventionl. In a spool or reel, the combination with a hollow spindle, the bushing located in the end and engaging the innerside thereof', having the fiange, of the end disk having the ceutral aperture,and the locking lnembereXteuding through the aperture in the disk and engaging the interior of the bushing to secure the parts.

2. In a spool or reel, the combination with the hollow spindle, the collars in the ends thereof engaging the inner sides and forming bushings and having the outwardly-extending flanges thereon, of the end disks having the apertures and engaging the lianges on the bushing,the collars extending through the apertures in the disks and engaging the interior of the bushings, and the flanges on the collars engaging the faces of the disks.

3. In a spool or reel, the combination with a hollow spindle, the collar forming the bushing seen red in the end of the spindle engaging the inner sides thereof and having the flange, and the end disk having the aperture, of the locking member having the flange engaging the exterior face of the end disk extending Ithrough the aperture and engaging the bushing in the spindle to secure the disk between the flanges.

4. In aspool or reel having the hollow spindle and the end disk having an aperture, the combination with a bushing secured in the end of the spindle, consisting of a collar having the iiauge upon its outer end, of' a locking member having the liange and the collar adapted to extend through the aperture in the enddisk and frietionally engage the interior of the bushing to lock the end disk tc the spindle.

5. In a spool or reel, the combination with a hollow tubular spindle of cardboard, the end disk formed of a single piece of similar material, and the metallic biniing-strip upon the edge thereof, of the metallic collar having the flange forming a bushing secured in the end of' the spindle, and a coperating member having the flange and the collar engaged in the bushing to secure the disk between the flanges.

6. In a spool or reel, the combination with the hollow spindle of cardboard, the end disks, each formed of cardboard having the metallic binding-strip at the edges, and the central apertures, of the securing-collars formed of sheet material provided with the flanges engaging the outer faces of' the disks, and the central tubular portions extending through the apertures and engaging the inner sides of the spindle.
