To provide, an improved method for con 1 structing such a reel.'

. To provide a reel that is made up of combined wire and sheet metal sections in order to make the reel strong and rigid in constrnction, light in weight and inexpensive in m its manufacture.

i To provide a reel in whlch the parts of the reel can be made up of finished material having a suitable finishing coating in order to eliminate thefinishing oi the reel after it has :loeen assembled.

All these and other objects of this mven- :tion will ,be apparent from the accompanying drawings, thespecification and the appended claims forming a part thereof.

The construction of the reel and its methyt5 and since issued as Patent 1,819,707, 'on

'5 0d of manufacture forming the subject matso as to provide a keyway 8A the full length The outer or free ends 10 and-11 of "thetriter of thisinvention makes possible the man-' u'factuze of a reel for moving picture films which: is strong and rigid in construction and cheaperin cost than any reel which has heretofore been made. An important feature in v the construction of the improved reel lies in the-combination ofwire sections and sheet metal sections and the manner in which these sections are fastened together to produce the finished reel.

In the form illustratedin Figures 1 and Q'the reel comprises the sides 1 and 2 which arespaced by the sheet .metalhub 3. Each, side of the reel in. turn is made up of the tubular rim 4, three 'pairs'of spokes '5, 5 and as the hub plate '6. The hub 3 is provided at each end with the tongues 7,7 which engage and project thru suitable slots '8 provided in each of the hub plates and when turnedfldown on the outside of the hub plates, as. illus- .trated in Figures 1 and 2, clamp the sides of the reel against the sheet metal hub. A sleeve 8' extends from the central openingv of one hubf'plateto that of the other and its ends are expanded and flare-d on the outside 7.

of :the openings to hold the sleeve in place therein and provide the bearing with an elongated bearing surface in the reel. The sleeve and the openings in the hub plate'are formed of the bearing.

Eachside ofj the reel, as above pointed out.

is constructed with a. tubular sheet-metal rim 4,the double spokes 5, 5 and the hub plate 6. The double spokesare formed by a triangularly bent "Wire inwhich'theiapex 9 is rounded to provide the connecting-member between the inner ends of the double spokes.

angular wire 'lorin are bent outwardly and concentric to the rim 4 in which they are anchored. as will hereinafter befidescribed. The curved connecting member between the innerends of the double spokes is clamped to the face of the hub plate which, for this purpose, is provided witha series of upturned flanges '12, 12. These flanges have a curved outline which corresponds with the curvature of the connecting sections of the inner ends ofthe spokes. The curved flanges From an inspection of Figure 1 it will be seen that the curved connecting section between each pair of spokes extends from the periphery well toward the center of the hub plate so that by clamping this portion of the spokes to the hub plate, in the manner shown and described, the spokes are not only clamped against it but are also rigidly held in place on the hub plates and for all practical purposes form an integral part therewith.

In the modification of the construction of the reel illustrated in Figures 4, 5 and 6 the inner curved connecting sections of the double spokes are clamped in place between a hub plate that is made up in two parts. Each part of the hub plate comprises a plate 15 having a series of curved grooves 16 formed therein corresponding in outline to the curved connecting sections of the double spokes 5,5. The grooves in two of the plates, which together make up a hub plate, face each other and are deep enough to receive the curved connecting ends of the double spokesso that when these individual plates are clamped together they firmly hold the inner ends of the spokes anchored in place between them.

In the construction illustrated in Figures 7 and 8 four sets of double spokes are used. This is necessary in reels having a large diameter. The hub plate 17 used for this form of reel is therefore provided with four flanges that clamp the inner ends of the double spokes in place and in addition the hub plates are connected by an intermediate hub sleeve 18 which is located between the hub sleeve proper 19 and the bearing sleeve 20 to increase the strength and rigidity of the hub plates. Another change in the construction of the larger reels is in the outer ends of the spokes 5, 5 which are anchored in the tubular rim. These ends instead of being short in length and being bent to project in opposite directions are long and project in the same direction. Their length extends between the outer ends of the radial portions of the spokes and thus completely fill the tubular rim which surrounds them. The laterally projecting ends of each pair of spokes in this way fills the space in the tubular rim between its radially projecting sections and the space between these sections and the radial sections of the adjacent pair .of spokes. With the increase in the number of spokes the rigidity of the tubular rim which con nects them is alsothus increased.

In order to prevent the sides of the hub plates, which project above the hub, from coming in contact with the edge of the film as it is wound onto or unwound from. the

reel, these outwardly projecting portions of the hub plates, which are located between each pair of spokes, are bent outwardly be-- tween the spokes as illustrated near the bottom in Figure 2 and near the'top and bottom in Figure 8. The outer edges of these outwardly projecting flanges of the hub plates are thus located between the spokes and cannot come .in contact with the edges of the film that is wound on the reel.

As will be apparent from the drawings and the description of the construction of making the reel, the surfaces of the material that are cut in the manufacture of each part of the reel are practically negligible in area and some of them are even concealed after the parts have been assembled. For this reason the material, that is the wire and the sheet metal stock, can be provided'with a finishing coat before it is made up into the different parts so that after the parts are assembled and the reel is mechanically finished no further finishing or coating need be given to the reel to provide a finished appearance for it.
