Abstract
Abstract A replaceable stripper tip for the end stripper which strips material such as hot pelletized ore from the discharge end of a traveling grate conveyor such as that used in a Grate-kiln system or the like, and a cooperating main body portion of the stripper which is adapted to receive the replaceable stripper tip. The stripper tip member is adapted for slip-on (or off) engagement with or disengagement from the main body member of the stripper by the use of clip-like lug means or the like on one of said members which interengage with cooperating surfaces on the other of said members. Additionally, the detachable stripper tip when in position is held firmly engaged with the main body of the stripper by a downward tension exerted by a ''''let-down'''' bar and associated chain and weight connected to the stripper tip, the ''''let-down'''' bar and associated chain and weight also performing the function of limiting the degree of pivotal opening of the empty conveyor grates as they move downwardly toward the lower run of the conveyor.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
137 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, and a replaceable stripper tip member adapted to be detachably mounted on said main body member at the stripping end of said stripper, lug-like means on one of said members adapted to detachably interengage with cooperating surfaces on the other of said members, and means on one of said members adapted to be connected to a normally downwardly acting tension means whereby the tension means when connected to said last-mentioned one member acts to engage said stripper tip member and said main body member in firmly assembled relation with each other.
Claim 2
Dependent Claim
137 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, and a replaceable stripper tip member adapted to be detachably mounted on said main body member at the stripping end of said stripper, lug-like means on one of said members adapted to detachably interengage with cooperating surfaces on the other of said members, and means on one of said members adapted to be connected to a normally downwardly acting tension means whereby the tension means when connected to said last-mentioned one member acts to engage said stripper tip member and said main body member in firmly assembled relation with each other.
Claim 3
Dependent Claim
23 words
An end stripper as defined in claim 1 in which said stripper tip member is adapted to be connected to said tension means.
Claim 4
Dependent Claim
52 words
An end stripper as defined in claim 2 in which said replaceable stripper tip member is adapted to be connected to a ''''let-down'''' bar which applies downward tension to said stripper tip member whereby to engage said stripper tip member and said main body member in firmly assembled relation with each other.
Claim 5
Dependent Claim
66 words
An end stripper as defined in claim 3 in which a chain is connected to said ''''let-down'''' bar contiguous an end of said ''''let-down'''' bar in spaced relation to the connection of said ''''let-down'''' bar to said stripper tip, and a weight is connected to said chain contiguous an end of said chain in spaced relation to the conNection of said chain to said ''''let-down'''' bar.
Claim 6
Dependent Claim
121 words
An end stripper as defined in claim 1 in which said stripper tip member 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 member additionally including second lug-like means contiguous the stripping edge of said tip member 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, and projection means carried by and extending downwardly from said stripping tip member in its assembled position and adapted to be pivotally connected to said tension means.
Claim 7
Dependent Claim
45 words
An end stripper as defined in claim 5 in which said main body member is provided with additional aperture means for receiving said projection means of said stripper tip and said projection means extends through said additional aperture means for connection to said tension means.
Claim 8
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 9
Dependent Claim
86 words
An end stripper as defined in claim 7 in which said main body member of said end stripper is provided with laterally space oppositely disposed rib members projecting in a normally downward direction from the under surface of said main body member, said rib members extending in a direction lengthwise of said main body member substantially to said forward edge, and slot means in said underhung edge of said stripper tip adapted to interegage with the ends of each said rib members contiguous said forward edge.
Claim 10
Dependent Claim
131 words
A replaceable stripper tip for the end stripper of a grate conveyor or the like in which said end stripper comprises a main body portion adapted to be supported by stationary support structure at a location in spaced relation from the stripping end of said stripper, said stripper tip being adapted to detachably engage said main body portion of the stripper and including lug-like means adapted to detachably interengage with cooperating surfaces on said main body portion, and additional means projecting downwardly from the normally under surface of said stripper tip and 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 portion in firmly assembled relation with each other.
Claim 11
Dependent Claim
