Positive flow vibratory feeder
First Claim
1. A positive flow vibratory feeder for objects having uniform thickness, said feeder comprising:
- a. a base;
b. a support element extending along a feed path and lying generally in a first plane;
c. means mounted on said base for vibrating said support element in a second plane generally perpendicular to said first plane and extending along said feed path, the direction of the vibration produced by said vibrating means being at an angle between said first plane and a third plane generally perpendicular to both said first plane and said second plane and transverse to said support element;
d. said support element being covered with a feed pile material along said feed path, said feed pile material having resilient bristles of uniform length;
e. said feed pile bristles being uniformly inclined by 5°
to 25°
toward the direction of feed from said third plane;
f. a holder mounted on said base and fixed relative to said support element, said holder extending generally parallel with said support element in a fourth plane generally parallel with said first plane so said holder is uniformly spaced from said feed pile material;
g. holding pile material arranged on said holder and having resilient bristles of uniform length extending toward said feed pile bristles.h. the tips of said holding pile bristles being spaced from the tips of said feed pile bristles by slightly less than said thickness of said objects to hold said objects in engagement with the tips of said feed pile bristles during said vibration; and
i. said holding pile bristles being inclined toward said direction of feed at an angle between said third plane and said fourth plane to flex periodically as said objects move against said holding pile bristles in response to one stroke of said vibration and to urge said objects periodically toward said feed pile bristles in response to the other stroke of said vibration.

Abstract
A positive flow vibratory feeder uses a support element extending along a feed path and vibrated in a plane perpendicular to the support element and extending along the feed path. The support element is covered with a feed pile material having resilient bristles of uniform length uniformly inclined toward the direction of feed from a plane generally perpendicular to the support element and transverse to the support element. A fixed holder generally parallel with the support element and spaced from the feed pile material is covered with pile material having resilient bristles of uniform length extending toward the feed pile bristles. The tips of the holding pile bristles are spaced from the tips of the feed pile bristles by slightly less than the thickness of the objects being fed to hold the objects in engagement with the tips of the feed pile bristles during vibration, and the holding pile bristles are inclined toward the direction of feed to cooperate with the feed pile bristles to produce a positive flow for said objects.
