Abstract
Abstract A conveyer for a slurry hose transportation system which has a plurality of wheel-supported carts and a linkage system interconnecting the carts. The conveyer provides means for transporting the carts and slurry system through a 180* turn by lifting the wheels from engagement with the ground and directing the linkage during the 180* turn. In one form, the linkage is restrained to a particular geometry so that the hose will maintain a predetermined minimum arc, thereby preventing damage to the preferred slurry hose.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
In a system for transporting a slurry from a mining machine in a mine having a floor, and which includes at least one flexible hose supported by a pLurality of wheeled carts spaced along the length of the hose and links pivotally interconnected with one another and the carts for pivotal movement in a horizontal plane, and wherein the hose is required to be transferred in a 180* bend between a storage section and a parallelly located active section as the need for the hose changes, the improvement comprising: a conveyer movably supporting the hose, carts and links off of the mine floor in the 180* bend portion of the hose, and means attached to the conveyer for moving the conveyer along the mine floor parallel to the storage section of the hose as the hose is being transferred between the active and storage sections.
Claim 2
Dependent Claim
145 words

Claim 3
Dependent Claim
30 words
The improvement defined in claim 1 wherein the conveyer includes a platform extending above the mine floor to support the wheels of the cart and thereby the hose and links.
Claim 4
Dependent Claim
54 words
The improvement defined in claim 2 wherein the platform is supported substantially parallel to the mine floor, and characterized further to include ramps extending from the platform to the mine floor arranged to engage the wheels of the carts as the conveyer is moved to move the carts onto and off of the platform.
Claim 5
Dependent Claim
65 words
The improvement defined in claim 1 wherein discs are journaled to the links to turn in a horizontal plane, and wherein the conveyer includes a platform extending above the mine floor to support the wheels of the carts, and an arcuate guide plate protruding above the platform arranged to engage the discs and guide the hose, links and carts during movement thereof over the conveyer.
Claim 6
Dependent Claim
47 words
The improvement defined in claim 1 wherein the conveyer includes a pair of parallel side panels extending substantially in a semi circle when viewed in plan, and rollers journaled between the side panels arranged to engage and movably support the links and thereby the hose and carts.
Claim 7
Dependent Claim
29 words
The improvement defined in claim 5 wherein the side panels slope upwardly from the ends thereof for raising and lowering the links, hose and carts moving over the conveyer.
