REEL

Filed May 20. 1927 INVENTOR BY WW. ATTORN Patented Feb. 9, 1932 UNITED STATES PATENT OFFICE llAIRlL E. ANDERSON, 01! EAST ORANGE, NEW JERSEY, ASSIGNOB TO EASTERN TOOL MANUFACTURING 00., BLOOMFIIELD, NEW JERSEY Application filed May 20,

This invention relates to an improved reel tor moving picture films and has for its object to provide a reel that is strong and can be cheaply made and is open at the sides to it such an extent as to enable access to ct the roll ct film when it becomes necessary to do so.

Another object oi the invention is to provide a reel with a smooth and even juncture ill) at the hub and spokes of the reel so that the possibility of the edges of a film becoming caught in any part of the reel is minimized.

The invention is turther desig' led to provide a reel with the spokes and rim made'up ll"? oil a set ot wire sections which are embedded at their inner ends in a hub that is cast around them.

The invention also relates to the method of inalring up a series of wire sections which are all placed side by side to complete the side pieces or tlanges and then die-casting the hub around the inner ends of such wire sections to hold them in their relative positions and to form the complete reel.

The invention is illustrated in the accompanying drawings in which Figure 1 is a side view of a film reel embodying my invention. Figure 2 is a section of the central portion thereof but on an enlarged scale, this section being taken 011 a plane indicated by line Q2 in Figure l and Figure 3 is a similar section taken on line 3-3 in Figure 1. Figure 4; is a side view of one of the wire flange or side-piece sections employed in making the reel illustrated in Figure 1 and Figures 5 and 6 are modifications showing how the wire sections can be made to abut to form a relatively continuous flange or side-piece.

Films are wound on reels and require a reel thatwill not provide any projections or which the film can catch to interfere with its smooth travel in a camera or projector and I have devised a reel which is light in weight and which is provided with side pieces between which the film is coiled, these side pieces being made up of wire sections. For the purpose oi illustrating I show one form of section in ll'igure 4 consisting of an arm 10 which forms a spolre and a curved arm 11 which forms a part ot the rim when such sections are arthe sides 1927. Serial No. 192,828.

ranged side by side as shown in Figure 1 and these sections are then secured to a suitable hub which acts to hold these sections in place and in addition provides means for mounting the reel on a shaft so that the reel can be rotated.

In the form shown in Figures 1 and 4, the wire sections are made triangular, the ends of the wire forming one of the angles as at 12 which is opposite the curved or rim portion 11 and these ends '12 are secured to the hub usually by lacing these ends in a die cast machine an then casting the hub so as to embed these ends in the casting. Such cast hub is shown at 13 in Figure 1 and to make the securing of the wire more pronounced I usually offset the inner ends of the radial arms 10 of the wire sections as at 15, the illustration showing a crank-like end, although various other forms of corrugated ends may be used.

I alsofind that the making of the reel is easier by making the hub in half sections which are placed face to face and in the drawings I show

such half sections

16 and 17, each provided with its side-piece made of wire sections, the half sections being secured together by suitable means such as the rivets 18, these being usually placed in the recesses 24 of the hub sections, these recesses being made primarily for the purpose of reducing the weight of the reel. Light rivets may be used as I prefer to arrange keyways or tongue-and-groove faces on the hub sections, one section having projecting parts 20 which fit into corresponding recesses 21 on the other sections, four of these being sufficient to show that when the sections are put together these projections and recesses interlock and prevent rotated movement of one section relative to the other and the rivets 18 hold these half sections together. It will be evident that other means of securing these half sections together may be employed.

In the construction illustrated in Figure 5 I show sections with one spoke arm 10 and the radial arm 11, one end of the radial arm 11 being bent over as at 22 to rest against the spoke arm of the next succeeding section in order to make a substantially continuous rim. In Figure 6 I show a modification in which the free. end of the rim arm 11 of the prior section is cut as at 23 to fit against the curve of the next section, so as to form a continuous rim.

It will be evident that in manufacturing this reel the wire sections which are cheap to make are-assembled and while held in assembled position have their ends surrounded by a casting and the reel is then complete.

It will be evident that various changes can be made in the form of the parts without departing from the scope of the invention.

I claim:

1. A film reel comprising wire sections, each section having two arms, one arm to form :1 spoke and the other arm to form a segment of the rim these sections being ar ranged side by side to form an annular side piece and a hub to which the inner ends of the spokes are secured.

2. A film reel comprising parallel side pieces each formed of wire sections arranged side by side, each wire section consisting of asingle wire with two arms, one forming a spoke and the other a segment of a rim, and a hub to which the inner ends of the sections are secured.

3. A film reel comprising parallel side pieces each formed of wire sections arranged side by side, each wire section consisting of a single wire with two arms, one forming a spoke and the other a segment of a rim, and a cast hub in which the ends of the spokes are embedded.

4. A film reel comprising side pieces each composed of wire sections arranged side by side, the inner ends of said sections being olfset, and a cast hub in which said elf-set ends are embedded.

5. A film reel comprising a series of sections each formed of a single wire bent to form a spoke and to form a part of the rim, these sections being assembled to form parallel side-pieces, and a cast hub in which the inner ends of the spokes are embedded.

In testimony whereof I aflix my signature.
