Abstract
An elongated non metallic cylindrical tubular member is provided and adapted to be received in the feed tube of a bar feeding machine. The cylindrical member is provided with an inside diameter sufficient to receive bar stock therethrough and functions to cushion the impact of the bar against the feed tube thereby reducing the sound levels produced by the machine. The tubular member includes at least one end extending outwardly from one end of the feed tube and means mounted to the end of the tubular member to retain it in place.
Claims8
In combination with a machine of the type which operates upon a bar from which a work article is formed and including a feed tube through which the bar is fed, said tube having a first end positioned to feed the bar to said machine and a second, opposite end exposed for axially receiving the bar, sound deadening means comprising a non-metallic tubular cylindrical member adapted to fit within said tube and having an inside diameter larger than the diameter of said bar and at least one end of said member extending outwardly from said second end of said tube, a portion of said outwardly extending end of said sound deadening member being folded back upon itself to form an enlarged diameter portion having a circumferential edge which abuts said second end of said tube to prevent said sound deadening means from being moved axially inwardly into said tube with said bar.
In combination with a machine of the type which operates upon a bar from which a work article is formed and including a feed tube through which the bar is fed, said tube having one end positioned to feed the bar to said machine and its other end exposed for receiving the bar, sound deadening means comprising a non-metallic tubular cylindrical member adapted to fit within said tube and having an inside diameter larger than the diameter of said bar and at least one end of said member extending outwardly from the end of said tube, and means mounted to said exterior end of said tubular member to restrain said tubular member from moving longitudinally in the direction of said machine, said last-mentioned means comprising a tubular cylindrical segment adapted to fit around the outwardly extending end of said member, a portion of said end of said member folded over the outer periphery of said segment and a clamp member positioned around said folded portion to secure said segment between said member and said folded portion wherein said segment forms an enlarged diameter portion which is adapted to abut against the exposed end of said tube to retain said segment exteriorly of said tube.
