In operation, an endless-supply of coarse yarn is passed through trumpet 200 to lay in groove.44.l

Power unit 20 through shaft 21 and pinion 36will cause. shaft 23 to rotate through engagement of gear 35 with pinion 36. Geneva cam 33 rotating With shaft 23 through cam arm 201 fixed to Geneva camv 33, engages Geneva follower 43 to turn shaft 40 the equivalent of one index station on follower 43. The movement of shaft 40 causes indexing sprocket 42 to engage andtrotate indexing wheel 30 one station through indexing pins 47. As

previously described a staple is positioned ina notch 46,.

is shaped into a U and as indem'ngwheel 301s periodically rotated the staple is presented beneath. the endless supply of coarse yarn. Disk 167 forcesthe coarse yarn into. the U of the staple. Continuedrotation of indexingwheel 30 presents the particular groove 46 to the-station wherein a handle, preferably of wood, is placed in notch 46 by means of piston 56which pushes a handle out of hopper 50. Piston 56 is actuated by themovement of rim actuating cam 25 Working against roller 80 fixed to the end of cam follower arm 58. i As previously'described eliptical cam 27 fixed to shaft 23 positions anvil 125 beneath the base of the U of the 'wire' staple and drives the staple through the handle and against the hammer 153. At the same time hammer 153i folds the legs'of the wire staple .over into a locked position, uniting a Wooden handle to the continuous supply of' coarse yarn by means of the wire staple.

Continued rotation of the indexing wheel 30 brings the assembled unit to a position in front of rotary knife 65 which severs-the coarse yarn, thereby producing an individual mop. In order to insure the removal of the mop from groove 44, rim actuating cam 25 through 'projections*186 and. 187 reciprocates stem 191 to force 1y described;

In order to insure the placing of a wire staple in the the mop from groove 44. This movement was previous-- path of piston 104 as it passes through hopper 10.1 to

push a staple intonotch 46, hopper 101 is vibrated.

A shaft 205 rotatively mounted in bearings 206 and 207 fixed tolegs 12' and 13respectively is provided with V a sprocket 208 and a four pronged star wheel 210 which periodically abuts hopper 101 to vibrate it. A sprocket 32 is connected'to sprocket 208 by means of a chain 211. Shaft 23 revolves sprocket 32.
