Abstract
Abstract Hopper-type apparatus for feeding oriented shallow, flanged articles, such as jar caps, which includes a hopper having a rotating hopper bottom provided with a circular row of pins set into its surface in spaced relation to the wall of the hopper, and a ramp mounted in the lower part of the hopper, with its slope facing the direction of rotation of the bottom, and its lower end contacting the same, to thereby raise articles from the hopper bottom moved by the rotation thereof and drop them over the pins passing the ramp.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
Apparatus for the oriented feeding of articles, of the character described, comprising a hopper formed of a hollow cylinder, means supporting said cylinder with its longitudinal axis at an angle to the horizontal, a disc rotatably supported within said cylinder inwardly of its upper edge, means rotating said disc, said disc having a circular row of spaced pins set into the outer surface thereof in spaced relation to the cylinder wall, an outlet chute in the path of rotation of said pins having its inner edge substantially in contact with the surface of said disc at approximately its horizontal axis, and stationary means in the path of rotation of said disc for slidably elevating articles at the bottom of the hopper moved by said rotating disc for dropping over a pin passing said elevating means.
Claim 2
Dependent Claim
135 words
Apparatus for the oriented feeding of articles, of the character described, comprising a hopper formed of a hollow cylinder, means supporting said cylinder with its longitudinal axis at an angle to the horizontal, a disc rotatably supported within said cylinder inwardly of its upper edge, means rotating said disc, said disc having a circular row of spaced pins set into the outer surface thereof in spaced relation to the cylinder wall, an outlet chute in the path of rotation of said pins having its inner edge substantially in contact with the surface of said disc at approximately its horizontal axis, and stationary means in the path of rotation of said disc for slidably elevating articles at the bottom of the hopper moved by said rotating disc for dropping over a pin passing said elevating means.
Claim 3
Dependent Claim
53 words
The apparatus of claim 1, wherein said elevating means comprises a ramp fixedly supported in the lower portion of said hopper intermediate the wall of said cylinder and said row of pins, said ramp having its slope facing the direction of rotation of said disc with its lower end contacting the surface thereof.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1, wherein said elevating means is disposed at substantially the midpoint between the horizontal and vertical axes of said disc.
Claim 5
Independent Claim
23 words
The apparatus of clam 2, wherein said ramp is disposed at substantially the midpoint between the horizontal and vertical axes of said disc.
Claim 6
Independent Claim
23 words
The apparatus of clam 2, wherein said ramp is disposed at substantially the midpoint between the horizontal and vertical axes of said disc.
Claim 7
Dependent Claim
21 words
The apparatus of claim 2, wherein said ramp is pivotally supported by its higher end on the wall of said cylinder.
