Abstract
Abstract A mobile apparatus (20) has a hydraulically operated pivoted boom (22) and a hydraulically operated pivoted arm (24) and on the free end of the arm is a hydraulically operated mechanism (26) for handling heavy loads in ways that cause torsional and bending distortion of the boom (22) and the arm (24). Coplanar steel hydraulic conduits (42a and 42b, and 45a and b to 50a and b) are slidably carried in conduit support blocks (57); and those blocks in turn are mounted on brackets (53) fixed to the arm (24) or brackets (69) fixed to the boom (22) by carrying means (56 or 72) which allows directionally unrestricted limited movement of the blocks (57) in a plane parallel to that of the conduit centers, and which also allows axial movement along lines perpendicular to that plane.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
In a mobile apparatus (20) having a hydraulically operated, pivotally mounted beam means (24 or 22) a free end of which supports a hydraulically operated mechanism (26) for handling heavy loads, means (52 or 51) mounting a plurality of rigid hydraulic conduits (42b or a and 45b or a to 50b or a) on said beam means (24 or 22) comprising, in combination: bracket means (53 or 69) fixedly mounted on said beam means; a hydraulic conduit support block (57) having a plurality of spaced coplanar holes (64) each of which receives and supports one of said plurality of conduits for endwise sliding movement; and carrying means (56 or 72) mounting said support block on said bracket means, there being clearances between parts of said bracket means and parts of said carrying means to permit directionally unrestricted limited relative movement between the bracket means and the support block in a plane parallel to the plane of said coplanar holes, and relative axial movement therebetween perpendicular to said plane.
Claim 2
Dependent Claim
168 words
In a mobile apparatus (20) having a hydraulically operated, pivotally mounted beam means (24 or 22) a free end of which supports a hydraulically operated mechanism (26) for handling heavy loads, means (52 or 51) mounting a plurality of rigid hydraulic conduits (42b or a and 45b or a to 50b or a) on said beam means (24 or 22) comprising, in combination: bracket means (53 or 69) fixedly mounted on said beam means; a hydraulic conduit support block (57) having a plurality of spaced coplanar holes (64) each of which receives and supports one of said plurality of conduits for endwise sliding movement; and carrying means (56 or 72) mounting said support block on said bracket means, there being clearances between parts of said bracket means and parts of said carrying means to permit directionally unrestricted limited relative movement between the bracket means and the support block in a plane parallel to the plane of said coplanar holes, and relative axial movement therebetween perpendicular to said plane.
Claim 3
Dependent Claim
126 words
The combination of claim 1 in which said bracket means (53) comprises a pair of aligned arms (55) mounted on and extending laterally outwardly from opposite sides (37) of the beam means (24), and said carrying means (56) comprises two rigid mounting members (58), first bolt (59) and spacer (60) means connecting each said mounting member (58) to one of said arms (55) for limited movement along the axis of each bolt (59) of said first bolt and spacer means, and second bolt (66) and spacer (67 and 68) means connecting opposite end portions of said conduit support block (57) to said mounting members (56) for said directionally unrestricted limited movement about the longitudinal axis of each bolt (66) of said second bolt and spacer means.
Claim 4
Dependent Claim
77 words
The combination of claim 2 in which said second bolt (66) and spacer (67 and 68) means allows for limited movement of each of the opposite end portions of said conduit support block along the axis of each bolt (66) of said second bolt and spacer means, and said first bolt (59) and spacer (60) means and said second bolt (66) and spacer (67 and 68) means are in different planes that are transverse to said plane.
Claim 5
Dependent Claim
55 words
The combinaton of claim 1 in which the longitudinal axes of the rigid hydraulic conduits (42b or a and 45b or a to 50b or a) are substantially parallel to a top surface (35 or 32) means of the beam (24 or 22) means and said plane is also substantially parallel to said top surface.
Claim 6
Dependent Claim
128 words
The combination of claim 4 in which said bracket means (53) comprises a pair of aligned arms (55) mounted on and extending laterally outwardly from opposite sides (37) of the beam means (24), and said carrying means (56) comprises two rigid mounting members (58), a first bolt (59) and spacer (60) means connecting each said rigid mounting member (58) to one of said arms (55) for limited movement along the axis of each bolt (59) of said first bolt and spacer means, and second bolt (66) and spacer (67 and 68) means connecting opposite end portions of said conduit support block (57) to said mounting members (56) for said directionally unrestricted limited movement about the longitudinal axis of each bolt (66) of said second bolt and spacer means.
Claim 7
Dependent Claim
130 words
The combination of claim 1 in which the bracket means comprises a bracket plate (69) having a fastening portion (70) abutting and fixed to a top surface (32) of the beam means (22) and an integral support arm portion (71) substantially parallel to said top surface, and the carrying means (72) comprises a rigid mounting bar (73) which has portions (74) abutting and secured to the underside of said conduit support block (57) and an intermediate bracket arm engaging portion (75) slightly wider than the width of said support arm portion (71) and spaced from said underside by a distance slightly greater than the thickness of said support arm portion, and limiting means (69--69) are provided for restricting movement of said conduit support block (57) longitudinally of the support portion.
Claim 8
Dependent Claim
84 words
The combination of claim 6 in which said limiting means comprises a second conduit support block (57) spaced longitudinally of the conduits from said conduit support block (57), a second bracket plate (69) which has its fastening portion (70) closest to the fastening portion (70) of the first bracket plate (69), and means (72) securing said second conduit support block (57) to said second bracket plate (69), whereby each bracket plate (69) limits movement of the conduit support blocks (57) longitudinally in one direction.
