Total Claims: 7
Claim 1
Independent Claim
158 words
A hydraulic line assembly for use on an extensible boom having a fluid supply source, a non-extending base section and a movable arm section extending outwardly from said base section, said assembly comprising, a rigid conduit assembly having at least two independent fluid transfer conduits, said rigid conduit assembly having its forward end attached adjacent the forward end of such movable arm and its rearward end slidably mounted on such base section, a plurality of flexible conduits positioned adjacent such base section, said flexible conduits having forward ends attached to and in fluid communication with said independent fluid transfer conduits, their other ends being in communication with the fluid supply source, and a housing positioned on the exterior of the non-extending base section, said housing defining a chamber for receiving said flexible conduits and stationary divider means mounted within said housing for maintaining separation between portions of said flexible conduits during extension and retraction of the movable arm.
Claim 2
Dependent Claim
158 words
A hydraulic line assembly for use on an extensible boom having a fluid supply source, a non-extending base section and a movable arm section extending outwardly from said base section, said assembly comprising, a rigid conduit assembly having at least two independent fluid transfer conduits, said rigid conduit assembly having its forward end attached adjacent the forward end of such movable arm and its rearward end slidably mounted on such base section, a plurality of flexible conduits positioned adjacent such base section, said flexible conduits having forward ends attached to and in fluid communication with said independent fluid transfer conduits, their other ends being in communication with the fluid supply source, and a housing positioned on the exterior of the non-extending base section, said housing defining a chamber for receiving said flexible conduits and stationary divider means mounted within said housing for maintaining separation between portions of said flexible conduits during extension and retraction of the movable arm.
Claim 3
Dependent Claim
54 words
A hydraulic line assembly according to claim 1 wherein said stationary divider means commprises a longitudinally extending shield having a first end connected to said non-extending base section and within said housing and a second end spaced from said first end whereby said shield separates folded portions of said flexible conduit within said housing.
Claim 4
Dependent Claim
41 words
The hydraulic assembly of claim 2, including guide means for slidably retaining said rigid conduit assembly adjacent said base portion, said guide means comprising a bearing rigidly mounted to said non-extending base section, said bearing slidably receiving said rigid conduit assembly.
Claim 5
Dependent Claim
28 words
The hydraulic line assembly of claim 2 wherein said rigid conduit, in a fully retracted position of the movable arm, extends approximately the length of the base portion.
Claim 6
Dependent Claim
12 words
Apparatus according to claim 2 wherein said rigid conduit comprises concentric tubes.
Claim 7
Dependent Claim
19 words
The apparatus according to claim 2 wherein said plurality of flexible conduits are bound together substantially throughout their length.
