Abstract
Abstract An apparatus for controlling the flow of articles being fed to a case packer in rows upon a conveyor. The case packer has an article supporting member which is shifted laterally for depositing a predetermined number of articles into the case. The apparatus includes a plurality of vertically extending abutments which are carried below the path of travel of the articles between the conveyor and the case packer. The vertically extending abutments are selectively raised into the path of travel of the articles for preventing the articles from being fed from the conveyor onto the article supporting member when articles are being deposited into the case.

Claim 1
Independent Claim
230 words
An apparatus for controlling the flow of articles being fed to a case packer in rows on a transporting surface of a conveyor, said case packer having an article supporting member which is shifted for depositing a predetermined number of articles into a case, said apparatus comprising: a. a vertically extending plate carried between said case packer and said conveyor below the transporting surface of said conveyor; b. a plurality of vertically extending abutments normally carried below the path of travel of said articles on an upper edge of said vertically extending plate; c. an outwardly extending shaft carried on said article supporting member; d. an inclined slot provided in said vertically extending plate; e. means for shifting said article supporting member laterally between a position wherein said articles are deposited into said case and a position wherein said articles are supported above said case; f. said shaft extending through said slot in said vertical plate for raising and lowering said vertical plate as said article supporting member is shifted laterally between a position wherein said articles are deposited into said case and a position wherein said articles are supported above said case; whereby as said article supporting member is shifted for depositing said articles supported thereon into said case, said flow of articles being fed on said conveyor is restrained by said raised abutments during the case loading operation.
Claim 2
Independent Claim
230 words
An apparatus for controlling the flow of articles being fed to a case packer in rows on a transporting surface of a conveyor, said case packer having an article supporting member which is shifted for depositing a predetermined number of articles into a case, said apparatus comprising: a. a vertically extending plate carried between said case packer and said conveyor below the transporting surface of said conveyor; b. a plurality of vertically extending abutments normally carried below the path of travel of said articles on an upper edge of said vertically extending plate; c. an outwardly extending shaft carried on said article supporting member; d. an inclined slot provided in said vertically extending plate; e. means for shifting said article supporting member laterally between a position wherein said articles are deposited into said case and a position wherein said articles are supported above said case; f. said shaft extending through said slot in said vertical plate for raising and lowering said vertical plate as said article supporting member is shifted laterally between a position wherein said articles are deposited into said case and a position wherein said articles are supported above said case; whereby as said article supporting member is shifted for depositing said articles supported thereon into said case, said flow of articles being fed on said conveyor is restrained by said raised abutments during the case loading operation.
Claim 3
Dependent Claim
28 words
The apparatus as set forth in claim 1 wherein said plate upon which said abutments are carried is supported in a channel provided adjacent said article supporting member.
Claim 4
Dependent Claim
57 words
The apparatus as set forth in claim 1 wherein said inclined slot includes a horizontal portion which terminates in an upwardly inclined portion so that as said article supporting member is shifted laterally, said shaft moves freely through said horizontal portion until is reaches said inclined portion wherein it begins lowering said plate with said abutments thereon.
Claim 5
Dependent Claim
23 words
The apparatus as set forth in claim 1 wherein the sides of said abutments are inclined from adjacent their bottom towards their tops.
Claim 6
Dependent Claim
28 words
The apparatus as set forth in claim 1 wherein said abutments are inclined from adjacent their bottoms towards their tops in a direction of flow of said articles.
