Abstract
Abstract An improved wear strip construction for a conveyor. The conveyor includes a pair of spaced side walls and the upper and lower extremities of each side wall are provided with inwardly extending flanges. Metal wear strips are snap fitted on the upper flanges of the side walls and serve to support the side edges of a plastic link belt conveyor chain in a conveying path of travel, while a sinusoidal metal wear strip is supported on the lower flanges of the side walls and serves to support the link chain in its return path of travel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
In a conveyor system, a conveyor frame including a pair of generally parallel vertical walls, each of said walls having an upper flange and a lower flange with the upper flanges of said walls facing toward each other and the lower flanges of said walls facing toward each other, an upper wear strip secured to each upper flange, a lower wear strip of generally zigzag configuration supported on both the lower flanges of said walls, and a link belt endless conveying member mounted for travel on said frame in an upper path and a lower path, the side edges of said conveying member being supported on said upper wear strips when the conveying member is moving in its upper path of travel and said conveying member being supported on said lower wear strip when moving in its lower path of travel.
Claim 2
Dependent Claim
141 words
In a conveyor system, a conveyor frame including a pair of generally parallel vertical walls, each of said walls having an upper flange and a lower flange with the upper flanges of said walls facing toward each other and the lower flanges of said walls facing toward each other, an upper wear strip secured to each upper flange, a lower wear strip of generally zigzag configuration supported on both the lower flanges of said walls, and a link belt endless conveying member mounted for travel on said frame in an upper path and a lower path, the side edges of said conveying member being supported on said upper wear strips when the conveying member is moving in its upper path of travel and said conveying member being supported on said lower wear strip when moving in its lower path of travel.
Claim 3
Dependent Claim
61 words
The conveying system of claim 1, wherein said upper wear strip includes an edge portion having a reverse bend and disposed in engagement with the extremity of the respec-tive flange, and the opposite edge of said wear strip is hooked, said flange being provided with an outwardly extending lip disposed to be engaged by the hooked edge of the wear strip.
Claim 4
Dependent Claim
23 words
The conveying system of claim 2, wherein the reverse bend terminates in a free edge extending at an acute angle to the horizontal.
Claim 5
Dependent Claim
36 words
The conveying system of claim 2, wherein said upper wear strip has a flat upper surface disposed to support the conveying member and both said reverse bend and hooked edge extend downwardly from said upper surface.
Claim 6
Dependent Claim
45 words
The conveying system of claim 1, in which first spaced portions of each side edge of the lower wear strip are supported on the respective lower flanges and second portions of each side edge are spaced from the respective lower flange to provide openings therebetween.
Claim 7
Dependent Claim
18 words
The conveyor system of claim 1, wherein the wear strips are metal and the link belt is plastic.
