Abstract
Abstract A conveyor support way for a table top chain comprises a series of alternating first and second cross members in spaced disposition transverse to the axis of the conveyor support way. Each of the first cross members contains a first pair of open top spaces and each of said second cross members contains a second pair of open top spaces, the first pair of spaces being disposed laterally inwardly of the second pair of spaces. A pair of serpentine wear strips are provided to support the chain, each of the wear strips extending along the length of the series of cross members, alternately through an associated one of the first cross member spaces and through an associated one of the second cross member spaces. Each wear strip is axially slidably and easily removably mounted on the series of cross members.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
238 words
A conveyor support way for a table top chain comprising: (A) a series of alternating first and second cross members in spaced disposition transverse to the axis of said conveyor support way, each of said first cross members containing a first pair of open top spaces and each of said second cross members containing a second pair of open top spaces, said first pair of spaces being disposed laterally inwardly of said second pair of spaces; (B) a pair of serpentine wear strips, each of said wear strips extending along the length of said series of cross members, alternately through an associated one of said first cross member spaces and through an associated one of said second cross member spaces, and being axially slidably and easily removably mounted on said series of cross members; each of said wear strips is of generally rectangular cross-section with a longitudinally extending groove along each long side thereof to define an "I" cross-section, and each of said spaces of said first and second cross members having a minimum width greater than the maximum width of each said wear strip passing therethrough so that said wear strips sit loosely in said spaces, said wear strips being insertable into and removable from said cross member spaces without the use of tools by displacements of said wear strips relative to said cross members in a direction substantially perpendicular to the axis of said wear strips.
Claim 2
Dependent Claim
238 words
A conveyor support way for a table top chain comprising: (A) a series of alternating first and second cross members in spaced disposition transverse to the axis of said conveyor support way, each of said first cross members containing a first pair of open top spaces and each of said second cross members containing a second pair of open top spaces, said first pair of spaces being disposed laterally inwardly of said second pair of spaces; (B) a pair of serpentine wear strips, each of said wear strips extending along the length of said series of cross members, alternately through an associated one of said first cross member spaces and through an associated one of said second cross member spaces, and being axially slidably and easily removably mounted on said series of cross members; each of said wear strips is of generally rectangular cross-section with a longitudinally extending groove along each long side thereof to define an "I" cross-section, and each of said spaces of said first and second cross members having a minimum width greater than the maximum width of each said wear strip passing therethrough so that said wear strips sit loosely in said spaces, said wear strips being insertable into and removable from said cross member spaces without the use of tools by displacements of said wear strips relative to said cross members in a direction substantially perpendicular to the axis of said wear strips.
Claim 3
Dependent Claim
61 words
The way of claim 1 wherein each of said wear strips have a top, a bottom and a pair of opposite side surfaces connecting said top and bottom, each of said side surfaces defining a recess extending along the length of said side surface, each of said recesses being engaged by space-defining surfaces of both said first and second cross members.
Claim 4
Dependent Claim
20 words
The way of claim 2 wherein an upper edge of said space-defining surfaces is received in each of said recesses.
Claim 5
Dependent Claim
43 words
The way of claim 1 wherein an outwardly facing corner of the space-defining surface of a second cross member enters the inwardly facing groove and an inwardly facing corner of the space-defining surface of a first cross member enters the outwardly facing groove.
Claim 6
Dependent Claim
34 words
The way of claim 4 wherein said first cross member pair of spaces are contiguous and the sides thereof defined by opposite sides of a single open top slot of said first cross member.
Claim 7
Dependent Claim
36 words
The way of claim 5 wherein the inwardly facing grooves of said wear strips are in close and uninterrupted proximity to each other where said wear strips pass through said slot of said first cross member.
Claim 8
Dependent Claim
56 words
The way of claim 6 wherein said slot of said first cross member has a minimum width less than the sum of the maximum widths of both said wear strips and more than the sum of the maximum width of one of said wear strips and the minimum width of the other of said wear strips.
Claim 9
Dependent Claim
46 words
The way of claim 5 wherein said spaces of said second cross members are aligned to define a pair of planes and said spaces of said first cross members are aligned to define a third plane intermediate to and substantially equidistant from said pair of planes.
Claim 10
Dependent Claim
13 words
The way of claim 1 wherein said wear strips are of plastic material.
Claim 11
Dependent Claim
12 words
The way of claim 1 wherein said wear strips are resiliently flexible.
Claim 12
Dependent Claim
15 words
The way of claim 1 wherein said wear strips contact the bottoms of said spaces.
Claim 13
Dependent Claim
40 words
The way of claim 1 additionally including a single third cross member in spaced disposition with said other cross members, at least one of said wear strips being fixedly mounted on said third cross member to preclude axial sliding therebetween.
Claim 14
Dependent Claim
37 words
The way of claim 12 wherein one end of each of said wear strips is fixed mounted on said third cross member, and the other end of each of said wear strips is free for axial movement.
Claim 15
Dependent Claim
34 words
The way of claim 1 wherein said first cross member pair of spaces are contiguous and the sides thereof defined by opposite sides of a single open top slot of said first cross member.
Claim 16
Dependent Claim
27 words
The way of claim 1 wherein said wear strips are insertable into and removable from said first and second cross members spaces through the open tops thereof.
Claim 17
Dependent Claim
19 words
The way of claim 1 wherein each of said first and second cross members are parallel to each other.
Claim 18
Dependent Claim
21 words
The way of claim 1 wherein said wear strips are of a plastic material having a high thermal coefficient of expansion.
Claim 19
Dependent Claim
22 words
The way of claim 5 wherein said single open top slot is disposed equidistantly from the ends of said first cross members.
Claim 20
Dependent Claim
24 words
The way of claim 1 wherein said first and second cross members are rigid and said wear strips fit loosely in said open-top slots.
