PAPER REEL.

Application filed December 22, 1922. Serial No. 608,438. f

vmarked. thereon, which form a part of this specification. l

This invention Vrelates to aper reels and the primary object of the invention is to provide a hollow mandrel upon which paper may be wound so that the edges will not be marred or torn during the winding and so constructed that it canl receive at its respective ends flanged heads for properly guidin the paper during the unwinding operatiogn; the heads, of course, being removable when the paper is to be wound on the mandrel and receivable in the hollowi mandrel when the paper is to be unwound.

The prime features of the invention reside in the means by which the flanged heads can be attached to and removed from the mandrel as well as in the peculiar construction of the heads themselves.

The novel construction of the invention will be specifically referred to hereinafter, had to the 'accompanying drawings, in w 'ch Fig. 1 is a perspective view of a complete reel constructed in accordance with my invention.

Fig. '2 is an elevational view of the reel, part of the mandrel being broken away to show the location of one head.

Fig. 3 is a vertical, longitudinal, sectional view through a portlon of the mandrel and through one he Fig. 4 is an enlarged. detail view of the joint for connecting the flange to the head,

Fig. 5 is a vertical, longitudinal, sectional lview throughs. slightly modified funn of sad. A A..

Referring now to thev drawings by numerals of leference: v

I designates a hollow mandrel or tube i which preferably consists of paper board but consist of other material. The

which may 1 is adapted to received on a instance is provided with an elongated rib or protuberance 8, which may be struck-up from the metal of which the cup-shaped member consists, and as many of these protuberances may be formed in each head as are consideredadequate to engage the inner wall of the tube 1 so that the h will be held in place.

The outstanding protuberances or ribs 8 will embed themselves in the soft inner wall of the tubular member 1 when the head is put in place.

Each head has at its outer end an outstanding circumferential iange 9 adapted to be received in a groove 10 in the circumferential flange 11. Each iange 11 has a central openin the edge of which is bent back upon itse f to form a reinforcing fold 12 and then bent. around to form a spaced parallel wall 13 which provides the groove 10 receiving the flange 9.

The wall 13 may be bent over the tubular portion of the head 5, as at 14, to form a lock so that the flange 9 cannot become detached from the head to which it is secured. The periphery of the flange 11 is bent over to form a bead 15 to glive strength to the flange. The flanged head t and `have considerable stability and strength so it will be adapted to resist endwise play of 1the paper willenv it is wound upon the ree If desired a reinforcing disk 16 ma be received between the flange 9 and the w 13 so as to further strengthen the head, the disk 16 being provided with an openin 17 in line with the opening surrounded by t e collar7 so thatthe reel may be positioned onto a spindle about which the neel may turn.

The head vand ange may be constructed of relatively thin metal because the com struction is such that the head and ange' will .have considerable rigidity and resistance to distortion. 1 Such a. reel is easy to construct. The heads may be easily applied to and detached fromthe hollow manus formed will be rugged drcl or tube 1 and by winding the aper upon the mandrel or tube l prior to p acing the heads in position, it is obvious that there will be no frictional wear against the edges of the paper, which would cause them to tear or rub. This is important in certain types of paper, particularly that used for photographic purposes where the photographic or sensitized paper is wound upon a reel preparatory to passing it through a so-called photographic printing machine and it is for this purpose that I have particularly designedthe reel although I do not wish to be limited in all respects to its use in any particular place.

What I claim and desire to secure by Letters Patent is:

l. Y removable head for reels comprising a cylindrical member having one end turned inwardly to provide an inwardly projecting flange surrounding an opening, and the other end having an outwardly projecting flange, and a separate, ring-shaped flange member having a central opening, the metal of the flange member surrounding the central opening being bent back upon itself to form a reinforcing fold and then again bent in to form a wall in spaced relation to the fold whereby a groove is provided to receive the outwardly projecting flange on the end of the cylindrical member, the cylindrical member being adapted to be received in one end of a tubular mandrel upon which the material to be wound is received.

2. A removable head for reels comprising a cylindrical member having one end turned inwardly to provide an inwardly projecting flange surrounding an opening, the other end having an outwardly projecting flange,

a separate, ring-shaped flange member having a central opening, the metal of the flange member surrounding the central opening being bent back upon itself to form a reinforcing fold and then again bent in to form a wall in spaced relation to the fold whereby a groove is provided to receive the outwardly projecting flange on the end of the cylindrical member, the cylindrical member being adapted to be received in one e'nd of a tubular mandrel upon which material to be wound is received, and a reinforcing disk at the end of the cylindrical member, the outer edge of the reinforcing disk being received in the groove.

3. A removable head for reels comprising a cylindrical member having one end turned inwardly to provide an inwardly projecting flange surrounding an opening, the other end having an outwardly projecting flange and the body of the cylinder having longitudinal, elongated ribs projecting from its outer face, and a separate, ringshaped flange member having a central opening, the metal of the flange member surrounding the central opening being bent back upon itself to form a reinforcing ,fold and then again bent in to form a wall in spaced relation to the fold whereby a groove is provided to receive the *outwardly projecting ange on the end of the cylindrical member, the cylindrical member being adapted to be received in one end of a tubular mandrel upon which material to be wound is received.

In testimony whereof 'I affix my signature.

ARTHUR, W. CAPS.
