Abstract
Abstract A feeding system including a plurality of in-line vibratory conveyors in which bulk feed is transformed into uniform singlefile or column feed whereby product in flight from the system at any given time is equal. A hopper conveyor transfers multiple layers of product to a primary vibratory feeder in response to the demand as gauged by the total weight of the product in said feeder. The primary feeder subcombination employs horizontal section and a contiguous inclined section with a feeding step in between to form a wedge-shaped body of product for regulation of product flow and for thinning out of the product to a single layer with multiple rows. The product then enters a secondary vibratory feeder having its vibrator unit attached at an acute angle to the longitudinal axis of the feeder pan whereby the multirow flow is converted into the single-file flow against a side guide wall of the feeder pan.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A feeding system for establishing uniform product flow comprising a suPply hopper for storage and feeding of product, a primary vibratory feeder for receipt of said product from said hopper, weighing means to control the flow of product to said primary feeder in response to the weight of said product therein, means to restrict the flow of said product to form a wedge-shaped body of product along said primary feeder to assure thin layer flow of product therefrom, said wedge-shaped body including multilayer product to provide substantial weight independent of the product in said hopper, a secondary vibratory feeder for receipt of said thin layer flow of product from said primary feeder in multirow orientation, and means to cause said product to be fed from said multirow orientation tending toward the formation of a single-row stream in said secondary feeder, whereby regulation of said product is evenly distributed throughout the system and equal product in flight from the system at any given time is assured.
Claim 2
Dependent Claim
165 words
A feeding system for establishing uniform product flow comprising a suPply hopper for storage and feeding of product, a primary vibratory feeder for receipt of said product from said hopper, weighing means to control the flow of product to said primary feeder in response to the weight of said product therein, means to restrict the flow of said product to form a wedge-shaped body of product along said primary feeder to assure thin layer flow of product therefrom, said wedge-shaped body including multilayer product to provide substantial weight independent of the product in said hopper, a secondary vibratory feeder for receipt of said thin layer flow of product from said primary feeder in multirow orientation, and means to cause said product to be fed from said multirow orientation tending toward the formation of a single-row stream in said secondary feeder, whereby regulation of said product is evenly distributed throughout the system and equal product in flight from the system at any given time is assured.
Claim 3
Dependent Claim
78 words
The combination of claim 1 wherein said control means comprises a platform for mounting said primary feeder, means for supporting said platform for stabilized pivotal weighing movement, spring means for normally biasing said platform upwardly against the weight of said product, means for sensing the downward movement of said platform to roughly weigh the product and switch means for interrupting the operation of said hopper in response to said sensing means when a predetermined weight has been reached.
Claim 4
Dependent Claim
50 words
The combination of claim 2 wherein said supporting means includes a support tower, flexure plate means for pivotally connecting said platform to said tower, said flexure plate means extending in the direction of vibration of said primary feeder so as to prevent interference by the vibration with said weighing movement.
Claim 5
Dependent Claim
91 words
The combination of claim 2 wherein said primary feeder comprises a feeder pan that includes first and second sections and said restriction means is formed by the inclination of said second section, said inclination being sufficient to cause said thin layer of product to be a single layer and the center of gravity of said second section being positioned in substantial alignment with the pivot point of said weighing means to cause weighing of said product only in said first section to eliminate adverse effects due to thinning out of flow.
