Abstract
Abstract An end stripper for a traveling grate conveyor for positioning contiguous a lateral edge of the discharge end of the traveling grate conveyor, the end stripper including a detachable side wall which prevents lateral spillage of material passing over the end stripper. The end stripper includes a main body portion provided with a tapered interlocking web which is adapted to receive a detachable stripper side wall having a tapered T-slot which is adapted to interlockingly engage the tapered interlocking web carried by the main body portion of the end stripper when the side wall is slidably moved into interlocking engagement with the interlocking web. The end stripper also includes a replaceable or detachable stripper tip which is positioned in interlocking engagement with the main body portion of the end stripper after the side wall of the end stripper has been slid into position, with the replaceable stripper tip being so located and positioned relative to the detachable side wall of the end stripper that the replaceable stripper tip serves as an abutment which prevents removal of the detachable side wall from the main body portion of the end stripper as long as the replaceable stripper tip is engaged with the main body portion of the end stripper.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
195 words
An end stripper adapted to strip material being processed from the discharge end of a grate conveyor, said end stripper comprising a main body member adapted to be supported by stationary support structure at a location in spaced relation from the stripping end of said stripper, a detachable side wall member positioned at a lateral edge of said end stripper, cooperating means carried by said side wall member and by said main body member for slidably detachably interlocking said side wall member with said main body member of said end stripper, and a replaceable stripper tip adapted to be detachably mounted on said main body member at the stripping end of said stripper, said replaceable stripper tip when assembled on said end stripper being in obstructing relation to detaching movement of said side wall member whereby to retain said side wall member in assembled relation on said end stripper, said stripper tip being provided with means adapted to be connected to a normally downwardly acting tension means whereby the tension means when connected to said stripper tip acts to engage said stripper tip and said main body member in firmly assembled relation with each other.
Claim 2
Dependent Claim
195 words
An end stripper adapted to strip material being processed from the discharge end of a grate conveyor, said end stripper comprising a main body member adapted to be supported by stationary support structure at a location in spaced relation from the stripping end of said stripper, a detachable side wall member positioned at a lateral edge of said end stripper, cooperating means carried by said side wall member and by said main body member for slidably detachably interlocking said side wall member with said main body member of said end stripper, and a replaceable stripper tip adapted to be detachably mounted on said main body member at the stripping end of said stripper, said replaceable stripper tip when assembled on said end stripper being in obstructing relation to detaching movement of said side wall member whereby to retain said side wall member in assembled relation on said end stripper, said stripper tip being provided with means adapted to be connected to a normally downwardly acting tension means whereby the tension means when connected to said stripper tip acts to engage said stripper tip and said main body member in firmly assembled relation with each other.
Claim 3
Dependent Claim
48 words
An end stripper as defined in claim 1 in which one of said members is provided with means defining a slot and the other of said members is provided with means defining and interlocking web, whereby said interlocking web is received in sAid slot to interlock said members.
Claim 4
Dependent Claim
55 words
An end stripper as defined in claim 1 in which said main body member is provided with an interlocking web and said side wall member is provided with means defining a slot, said interlocking web being received in said slot whereby to interlock said side wall member and said main body member with each other.
Claim 5
Dependent Claim
66 words
An end stripper as defined in claim 1 in which said stripper tip member and said main body member define a pair of cooperating members, and one member of said pair of cooperating members is provided with lug-like means adapted to interengage cooperating means on the other member of said pair of cooperating members, whereby to interengage said stripper tip member with said main body member.
Claim 6
Dependent Claim
132 words
An end stripper as defined in claim 1 in which said stripper tip includes first lug-like means in spaced relation from the stripping edge of said tip member and adapted to be received through first aperture means in said main body member in detachably interengaged relation with said main body member, said stripper tip additionally including second lug-like means contiguous the stripping edge of said tip and adapted to underlie the forward edge of said main body member contiguous the stripping region and in detachably interengaged relation with said forward edge, said second lug-like means lying in obstructing relation to said means carried by said side wall member whereby to retain said side wall member in assembled relation on said end stripper when said stripper tip is assembled on said end stripper.
Claim 7
Dependent Claim
57 words
An end stripper as defined in claim 5 in which said second lug-like means of said stripper tip member is an underhung edge which is adapted to extend in underlying relation to said forward edge of said main body member for substantially the entire length of said forward edge in a direction laterally of the grate conveyor.
Claim 8
Dependent Claim
212 words
An end stripper adapted to strip material being processed from the discharge end of a grate conveyor, said end stripper comprising a main body member adapted to be supported by stationary support structure at a location in spaced relation from the stripping end of said stripper, a detachable side wall member positioned at a lateral edge of said end stripper, cooperating means carried by said side wall member and by said main body member for slidably detachably interlocking said side wall member with said main body member of said end stripper, and a replaceable stripper tip adapted to be detachably mounted on said main body member at the stripping end of said stripper, said replaceable stripper tip when assembled on said end stripper being in obstructing relation to detaching movement of said side wall member whereby to retain said side wall member in assembled relation on said end stripper, said stripper tip including projection means carried by and extending downwardly from said stripper tip in its assembled position, said projection means being adapted to be pivotally connected to a normally downwardly acting tension means whereby the tension means when connected to said stripper tip acts to engage said stripper tip and said main body member in firmly assembled relation with each other.
Claim 9
Dependent Claim
212 words
An end stripper adapted to strip material being processed from the discharge end of a grate conveyor, said end stripper comprising a main body member adapted to be supported by stationary support structure at a location in spaced relation from the stripping end of said stripper, a detachable side wall member positioned at a lateral edge of said end stripper, cooperating means carried by said side wall member and by said main body member for slidably detachably interlocking said side wall member with said main body member of said end stripper, and a replaceable stripper tip adapted to be detachably mounted on said main body member at the stripping end of said stripper, said replaceable stripper tip when assembled on said end stripper being in obstructing relation to detaching movement of said side wall member whereby to retain said side wall member in assembled relation on said end stripper, said stripper tip including projection means carried by and extending downwardly from said stripper tip in its assembled position, said projection means being adapted to be pivotally connected to a normally downwardly acting tension means whereby the tension means when connected to said stripper tip acts to engage said stripper tip and said main body member in firmly assembled relation with each other.
