Abstract
Abstract A centrifugal feeder is shown in which parallel rails are employed in a pick-off in combination with a plow having a cuvilinear pick-up point and a straight edge delivery to the parallel rails. The parallel rails deliver headed parts which are fed by the centrifugal feeder to a track for repositioning in various assembly units.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
234 words
A centrifugal feeder for symmetrical headed parts comprising, in combination, a rotary cone member, a cylindrical wall at the periphery of the rotary cone member, a drive means for the rotary cone member, means for tilting the axis of rotation of the rotary cone with respect to the vertical, a plow having a curved end portion bending substantially tangentially from the upper portion of the cylindrical wall, said curved plow terminating in a flat wall portion, a pair of parallel rails for carrying symmetrical headed parts terminating at one end in a curvilinear downwardly sloping portion defining a pick-up for such headed parts and terminating at the other end in a downwardly sloping portion for parts delivery, the ends of the curvilinear portion of such rails being positioned approximately so that the open portion therebetween is along the plane of the flat portion of the curved plow flat wall and thereagainst as a continuation thereof, said pick-up being further located in an area having a diameter substantially one-half of a radius of the conical rotary member, said circular area having its center along a radius parallel with the axis of tilt of the rotary conical member and midway between the center of the conical member and its circular periphery, and means for receiving the headed parts which are fed by the rotating conical member and picked up by the parallel rails for further processing.

Claim 3
Dependent Claim
38 words
In the centrifugal feeder of claim 1, a ramp fixed to the flat wall portion of the plow, said ramp having a height proportioned to drop headed parts elevated thereby onto the curvilinear portion of the parallel rails.
Claim 4
Dependent Claim
17 words
In the centrifugal feeder of claim 1, a meanS for adjusting the parallel spacing between the tracks.
Claim 5
Dependent Claim
36 words
In the centrifugal feeder of claim 1, the angle of said axis of rotation of said rotary cone member with the vertical exceeding the angle with the horizontal of the downwardly sloping portion for delivering parts.
