Abstract
Abstract A feeder for objects uses a vibratory element bearing a pile material having parallel bristles inclined in the direction of feed. The tips of the bristles engage and resiliently support objects to be fed, and the inclination of the bristles establishes the direction of feed as the element is vibrated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
A vibratory feeder comprising: a. an element extending in the direction of feed; b. means for vibrating said element; c. pile material carried on said element; d. said pile material having generally parallel bristles; e. said bristles being dense enough and strong enough so that the tips of said bristles support objects to be fed; f. said bristles being resilient relative to said objects to be fed; g. said bristles being inclined toward said direction of feed; h. said pile material including other generally parallel bristles having an inclination different from said direction of feed; i. said other bristles being interspersed with said feeding bristles inclined in said direction of feed, and said other bristles are taller and less stiff than said feeding bristles so said other bristles establish another direction of feed for lighter objects supported on the tips of said feeding bristles proceeding in said direction of feed.
Claim 2
Dependent Claim
150 words
A vibratory feeder comprising: a. an element extending in the direction of feed; b. means for vibrating said element; c. pile material carried on said element; d. said pile material having generally parallel bristles; e. said bristles being dense enough and strong enough so that the tips of said bristles support objects to be fed; f. said bristles being resilient relative to said objects to be fed; g. said bristles being inclined toward said direction of feed; h. said pile material including other generally parallel bristles having an inclination different from said direction of feed; i. said other bristles being interspersed with said feeding bristles inclined in said direction of feed, and said other bristles are taller and less stiff than said feeding bristles so said other bristles establish another direction of feed for lighter objects supported on the tips of said feeding bristles proceeding in said direction of feed.
Claim 3
Dependent Claim
105 words
A vibratory feeder comprising: a. an element extending in the direction of feed; b. means for vibrating said element; c. pile material carried on said element; d. said pile material having generally parallel bristles; e. said bristles being dense enough and strong enough so the tips of said bristles support objects to be fed; f. said bristles being resilient relative to said objects to be fed; g. said bristles being inclined toward said direction of feed; h. said pile material including a porous fabric backing; and i. fluid dispersing means for sending fluids to said fabric backing material and into the region of said bristles.
Claim 4
Dependent Claim
105 words
A vibratory feeder comprising: a. an element extending in the direction of feed; b. means for vibrating said element; c. pile material carried on said element; d. said pile material having generally parallel bristles; e. said bristles being dense enough and strong enough so the tips of said bristles support objects to be fed; f. said bristles being resilient relative to said objects to be fed; g. said bristles being inclined toward said direction of feed; h. said pile material including a porous fabric backing; and i. fluid dispersing means for sending fluids to said fabric backing material and into the region of said bristles.
Claim 5
Dependent Claim
108 words
A vibratory feeder comprising: a. an element extending in the direction of feed; b. means for vibrating said element; c. pile material carried on said element; d. said pile material having generally parallel bristles; e. said bristles being dense eNough and strong enough so the tips of said bristles support objects to be fed; f. said bristles being resilient relative to said objects to be fed; g. said bristles being inclined toward said direction of feed; h. said pile material including a backing material; i. said bristles being hollow and extending through said backing material; and j. fluid dispersing means arranged for sending fluid through said hollow bristles.
Claim 6
Dependent Claim
