Abstract
Abstract A trunnion bearing feeder is disclosed in conjunction with a rotary cone type feeder in which trunnion bearings or other parts having a long, cylindrical body and a pair of extensions at each end are to be fed into a tubular magazine at high rates of feed. A pick up tube is positioned within the bowl at its periphery tangential therewith, and downstream from the tube an adjustable venturi is provided which accomplishes the two-fold purpose of providing a vacuum to withdraw jammed parts into the pick up tube, and thereafter pressure feed the same into a delivery tube or magazine for further processing of the oriented parts. The venturi is a conical member which is threadedly engaged into a block having a conical recess whereby upon rotation of the threaded parts the venturi effort may be adjusted.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
220 words
A trunnion bearing feeder comprising in combination, - a feeder having a side wall, - the interior of said feeder having nesting means at its periphery cooperating with said side wall for aligning trunnion bearings in end to end single file orientation, said feeder having means for imparting movement to said trunnion bearings positioned therein to advance said trunnion bearings for further conveying from said periphery, - pick-up tube means tangentially aligned along a portion of the periphery of said feeder and in communication with said nesting means, - an adapter bracket provided in the side wall of said feeder having clamping means for securing said pick-up tube means in longitudinal relationship with said feeder and with said nesting means, - said pick-up tube means extending outwardly from said adapter bracket, - a venturi provided downstream of said pick-up tube means and in closed communication therewith to provide negative pressure within said pick-up tube means and positive pressure downstream of said pick-up tube means, - said venturi operationally functioning to introduce the trunnion bearings into said pick-up tube means in single and spaced relation one to the other and to draw the same into and through said venturi and to accelerate the same under positive pressure further downstream of said pick-up tube means in a continuous and uninterupted flow path.

A trunnion bearing feeder comprising in combination, - a feeder having a side wall, - the interior of said feeder having nesting means at its periphery cooperating with said side wall for aligning trunnion bearings in end to end single file orientation, said feeder having means for imparting movement to said trunnion bearings positioned therein to advance said trunnion bearings for further conveying from said periphery, - pick-up tube means tangentially aligned along a portion of the periphery of said feeder and in communication with said nesting means, - an adapter bracket provided in the side wall of said feeder having clamping means for securing said pick-up tube means in longitudinal relationship with said feeder and with said nesting means, - said pick-up tube means extending outwardly from said adapter bracket, - a venturi provided downstream of said pick-up tube means and in closed communication therewith to provide negative pressure within said pick-up tube means and positive pressure downstream of said pick-up tube means, - said venturi operationally functioning to introduce the trunnion bearings into said pick-up tube means in single and spaced relation one to the other and to draw the same into and through said venturi and to accelerate the same under positive pressure further downstream of said pick-up tube means in a continuous and uninterupted flow path.
Claim 3
Dependent Claim
74 words
The trunnion bearing feeder as set forth in claim 1 above, wherein said venturi comprises a conical member adjustably engaging a venturi block having a conical recess for receiving the same, means for adjusting the gap between the conical member and the conical receiving portion of the block, whereby the extent of the negative and positive pressure may be regulated by the positioning of the venturi cone and adjusting the angular side wall spacing.
Claim 4
Dependent Claim
62 words
The trunnion bearing feeder as set forth in claim 1 above, which further includes a tapered wall at the inlet portion of the pick-up tube means and forming substantially to the interior configuration of the side wall of the feeder, whereby the parts in the peripheral portion of the feeder and oriented within the nesting means are led into the pick-up tube.
