 crosspieces a circular metal band is supplied to hold the crosspieces 

 rigid. On these crosspieces holes are provided to receive metal 

 standards, around which is engaged the coil of wire. 



At one end of platform a brake is supplied, carrying a section of 

 light rope, by means of which the "unit " may apply the brake on the 

 circular band, thus regulating the "pay out" of wire as may be 

 determined. The brake as supplied on end rail is considered the front 

 or forward end of pack reel.

of platform. At the center of the cross arms a metallic cap is pro- 

 vicled at intersection of cross arms, a hole being provided at center of 

 cap, which engages over the vertical shaft, holding the cross arms 

 to place. 



Two circular bands are provided, spaced about 12 inches apart 

 by means of distance rods, the upper band being riveted to the hori- 

 zontal portion of cross arms; the lower band is connected to the ver-

 horizontal (hstance ])lates connect with the vertical rods near point of 

 engagement of the extremities of cross arms that engage on slots, as 

 provided on platform, metal keys being supplied to hold extremities 

 of cross arms rigidly in position to side rails of platform.
