" 7 This invention relates to a device for assisting in the u'nreeling of wire from a wire coil, which is particularly adapted to guide the wire in such'a manner that catching or snarling thereof is avoided so that the wire can continuously be removed from the coil and fed to anysuitable point of use.

. Adevice of this character preferably has a wire guidingmember so arranged that it conformsto the size of. the wire coils and permits the same to be arranged-in spirals as, the wire passes from the coil to the straight run lead-. ing'to the point ofuse. Thus theiguiding member preferably may be cylindrical and may have a diameter slightly smaller than the inner diameter of the coil from which the wire is to be removed. This member is preferably arranged in association with certain retaining elements, sothat the wire run is put under some tensionat the upper end of the guide member and so that the spiral closely conforms to the outersurface of that member at the point where the wire leaves the spiral and follows a more orless-straight path.

A suitable frame ispreferably arranged at either side of the guide member and'ha-s a portion extending above thesame withan opening adapted to receive the wire run and to provide an auxiliary guide for the same. The upper portion of the main guide .meinberis preferably connected to the frame member in such a manner that additional coils ofxw-ire may be readily located in concentricrelation to the guide member. Thus a, device con structed in accordance with ,the'pre'sentim vention permits the wire passing fromthe coil first to follow a spiral path, whichhas an average diameter somewhat greater than that of the cylindrical-guide member, thediameter of the spiral decreasing as the wire approaches the portion of the guide member which is engaged by theretaining 'mean'sy this retaining means preferably being yieldable or yieldably' mounted so that the u'pperip'or- 1 tion of the wire spiral adjoining the point where the wire'leaves'theguide memberpreferably conforms closely to the surface of that member. Thus thewire may'follow an indeterminate-path as it leaves the; .coil, but it is guided more accurately-res: its. distance.

It is, therefore ap parent that the minimum of difiiculty is, en countered in snarling or catching of wire coils upon each other, and it has been found 1n practice that a guiding device of this character permits the wire to be drawn rapidly and smoothly from a coil without catching or entanglement.

WVhi-l'e a comparativelylhigh'tension may be imposed upon the wire passing through loop 16, substantially all of this tension is opposed by the frictional engagement of the wire with the element 14: and the adjoining portion of guide 3, so that a comparatively light pull is imposed upon the wire convolutionswhich are wrapped aboutgui'de 3. Due to the natural tendency of these wire convolutions to retain substantially the shape originally imposed thereon when for-med intothecoil 1'8, they. do not tendto wraptightly-about the guide 3 accordingly the wire but loosely engages the latter and snubbingefi ect I claim:-
