Abstract
Abstract A gantry-less scraper device with a pivoted jib for the removal of material from a bulk storage dump having a dump delimiting wall at the machine side. The device travels along the machine side of the dump on a first rail spaced from the base of the delimiting wall and on a second rail on the side of the delimiting wall near its top. The device does not require a rail on the far side of the dump, does not require support from a shed over the dump, and does not require clearance for a counterweight.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
A material removing device for the removal of bulk material from a bulk storage dump, said dump being defined near its base by a dump delimiting wall having an inner and an outer face and a head face over which the bulk material is conveyed as it is removed from said dump, said device including a loader having a first jib pivotally mounted on a supporting means on said loader so as to be pivoted about a substantially horizontal pivot axis and extending over said dump; means for guiding and supporting said loader consisting of: a first track arranged adjacent the outer face of said dump delimiting wall below the head face thereof and a second track arranged above said first track on the outer face of said dump delimiting wall laterally below said head face; first wheel means on said loader traveling on said first track vertically and horizontally supporting said loader; second wheel means on said loader a distance above said first wheel means traveling on said second track and acting to laterally support said loader, thereby counteracting the tilting force of said loader created by the weight of said jib.
Claim 2
Dependent Claim
193 words
A material removing device for the removal of bulk material from a bulk storage dump, said dump being defined near its base by a dump delimiting wall having an inner and an outer face and a head face over which the bulk material is conveyed as it is removed from said dump, said device including a loader having a first jib pivotally mounted on a supporting means on said loader so as to be pivoted about a substantially horizontal pivot axis and extending over said dump; means for guiding and supporting said loader consisting of: a first track arranged adjacent the outer face of said dump delimiting wall below the head face thereof and a second track arranged above said first track on the outer face of said dump delimiting wall laterally below said head face; first wheel means on said loader traveling on said first track vertically and horizontally supporting said loader; second wheel means on said loader a distance above said first wheel means traveling on said second track and acting to laterally support said loader, thereby counteracting the tilting force of said loader created by the weight of said jib.
Claim 3
Dependent Claim
32 words
Device according to claim 1 wherein said second wheel means is mounted on said loader in a position under and in close proximity to said horizontal pivot axis of said pivoted jib.
Claim 4
Dependent Claim
34 words
Device according to claim 1 wherein said loader carries an upwardly projecting second jib, said second jib being shorter than the said first jib, and said first jib being suspended from said second jib.
Claim 5
Dependent Claim
34 words
The device according to claim 1 wherein said first wheel means travel on said first track and wherein the device has a pair of guide rollers one traveling at either side of said track.
Claim 6
Dependent Claim
23 words
The material removing device according to claim 1 wherein the loader is a scraper loader, and said first jib is a scraper jib.
Claim 7
Dependent Claim
92 words
Bulk storage means comprising a bulk storage dump, a dump delimiting wall having inner and outer faces and a material removing device moveable parallel to said wall and having a pivoted jib projecting over said wall and means for supporting and guiding said device consisting of: a first track beside and spaced from said outer face of said dump delimiting wall and a second track above said first track and on said dump delimiting wall and first and second wheel means on said device traveling on said first and second tracks respectively.
Claim 8
Dependent Claim
92 words
Bulk storage means comprising a bulk storage dump, a dump delimiting wall having inner and outer faces and a material removing device moveable parallel to said wall and having a pivoted jib projecting over said wall and means for supporting and guiding said device consisting of: a first track beside and spaced from said outer face of said dump delimiting wall and a second track above said first track and on said dump delimiting wall and first and second wheel means on said device traveling on said first and second tracks respectively.
Claim 9
Dependent Claim
30 words
Bulk storage means according to claim 6 wherein the said dump delimiting wall has a side face directly adjacent its top, and the second track is on said side face.
Claim 10
Dependent Claim
18 words
Bulk storage means according to claim 7 wherein the dump delimiting wall is buttressed on said inner face.
Claim 11
Dependent Claim
31 words
Bulk storage means according to claim 7 having a conveyor between the first track and said outer face of said delimiting wall for the removal of material scraped from the dump.
