ABSTRACT:
A sound-deadening device for use in a feed tube for bar stock includes a radially resilient sleeve having a relaxed diameter greater than the diameter of said tube so as to be held frictionally within the tube in a preselected position by expanding outwardly against the interior surface of the tube. Telescoped into the sleeve is a generally cylindrical backing having the outer ends of a plurality of generally radial bristles embedded therein. The bristles extend inwardly from the backing and include inner ends defining a central passage through the sleeve. The bristles support bar stock within the feed tube and, during rotation of the stock, resiliently cushion the stock against striking the interior of the tube thereby deadening the noise otherwise caused by rotation of the stock within the tube.
