=5 as shown, it is used in corinection with'what is known as the. Choquette ring placing machine wherein the rings are generally placed in large numbers upon a long rod whlch is suspended vertically'ov'er a slide ln-which slide'thereoperates a .10 ring pushing means which removes any number of rings at a time from the bottom of therodand carries it or them alon'g it or they drop from the horizontal part of thei"slide" into a' position vertically between the ring placing device and the head of a bobbin on which the rings "are suc'-.

'cessively to beplaced." The bobbin'is generally moved'towards the ringsi'andthe pushing device moves; the rings to andonto the bobbin in their proper places." i 'I do not claim anything new on the ring placmg devices-butthlsjinvention takesjthe place'of the long rod. 7 Its purpqse is to permit; a large number of rings to be dropped into a hopperfrorn which they are moved by, a revolving spider wheel.

and delivered to thetopend'ot a relatively'short floating rod inside or a receiving tube. Those rings which land on therod automatically "rest evenly one on top of the cither so that theonesat the bottom are'always horizontal andareal'wa'ys in the correct position in the 'slide.; If the rod is filled, the rings drop baclr into thesc'oop hopper and if there'are'any rings which donotland on vtopof the rodgthese falljback intof'thefscoop I hopper. a r f "In the drawing,
