Abstract
Abstract A filler for bins has a supply conveyor with a stationary initial portion and an end portion movable on said stationary portion to lift and lower in a bin in response to a jack controlled by either of two sensing panels on the margins of a deflector frame, hanging as a pendulum from said conveyor end portion, to lift said end portion when one of said sensing panels is abutted by produce in said bin.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A filler for bins comprising a supply conveyor having an end portion, means for moving said conveyor end portion into and out of a bin, a produce deflector frame depending from said end and having a pair of edge portions, a pair of sensing devices, means for movably attaching each of said sensing devices to each of said edges portions to depend therefrom substantially as a pendulum and in position on said deflector frame to be moved by abutting produce in said bin, and means responsive to pivotal movement of said sensing means for actuating said moving means to move said conveyor end portion out of said bin.
Claim 2
Dependent Claim
108 words
A filler for bins comprising a supply conveyor having an end portion, means for moving said conveyor end portion into and out of a bin, a produce deflector frame depending from said end and having a pair of edge portions, a pair of sensing devices, means for movably attaching each of said sensing devices to each of said edges portions to depend therefrom substantially as a pendulum and in position on said deflector frame to be moved by abutting produce in said bin, and means responsive to pivotal movement of said sensing means for actuating said moving means to move said conveyor end portion out of said bin.
Claim 3
Dependent Claim
26 words
A filler for bins as in claim 1 in which said produce deflector frame is pivoted to hang as a pendulum from said conveyor end portion.
Claim 4
Dependent Claim
28 words
A filler for bins as in claim 1 in which each of said sensing devices includes a marginal panel hingedly mounted along one edge of said deflector frame.
Claim 5
Dependent Claim
46 words
A filler for bins as in claim 3 in which said deflector frame includes means forming an upper surface sloping downwardly in opposite directions from the center toward said marginal panel along one edge and toward a duplicate of said marginal panel along the other edge.
Claim 6
Dependent Claim
34 words
A filler for bins as in claim 3 in which an electrical switch controlling said moving means is mounted on said deflector frame in position to be actuated by said marginal panel when moved.
Claim 7
Dependent Claim
36 words
A filler for bins as in claim 1 in which said supply conveyor has a relatively stationary initial portion and a relatively movable end portion pivoted about a horizontal axis to said relatively stationary initial portion.
