Abstract
Abstract An elongated controlling arm is hingedly connected at one end to the inner end of a dipper stick of an earth-moving crane to serve as a controller for hydraulic or pneumatic hoses which extend between the dipper stick and a boom on which the dipper stick is slideably mounted. A roller is mounted on the free end of the arm for rollably engaging the hoses. The arm is spring biased away from the boom so as to keep the hoses under tension in all positions of the boom and dipper stick. In addition, the connection of the controller arm to the dipper stick includes a pair of springs which resiliently hold the arm in contact with a bracket mounted on the dipper stick and allow the arm to be rocked from side to side in the bracket without becoming damaged or without damaging outside objects such as glass windows or siding of buildings.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
A hydraulic hose controller in combination with a device having a first member which is movably connected to a second member, said device having a source of hydraulic fluid under pressure connected to said first member, having a hydraulically operated device attached to said second member, and having hydraulic conduit means connected between said source of hydraulic fluid and said hydraulically operated device, which conduit means includes a flexible hydraulic hose portion connected between said first and second members, said hydraulic hose controller comprising a controller arm hingedly connected at one end to said second member for movement toward and away from the latter, guiding means on the other end of said controller arm engaged by a portion of said hydraulic hose intermediate its length, and biasing means between said second member and said controller arm normally urging the arm away from said second member to thereby continuously prevent slack in said hose.
Claim 2
Dependent Claim
153 words
A hydraulic hose controller in combination with a device having a first member which is movably connected to a second member, said device having a source of hydraulic fluid under pressure connected to said first member, having a hydraulically operated device attached to said second member, and having hydraulic conduit means connected between said source of hydraulic fluid and said hydraulically operated device, which conduit means includes a flexible hydraulic hose portion connected between said first and second members, said hydraulic hose controller comprising a controller arm hingedly connected at one end to said second member for movement toward and away from the latter, guiding means on the other end of said controller arm engaged by a portion of said hydraulic hose intermediate its length, and biasing means between said second member and said controller arm normally urging the arm away from said second member to thereby continuously prevent slack in said hose.
Claim 3
Dependent Claim
26 words
The combination as claimed in claim 1 in which there is means providing for yielding lateral movement of the controller arm in response to side impact.
Claim 4
Dependent Claim
20 words
The combination as defined in claim 1 wherein said guiding means includes roller means positioned to rollably engage the hose.
Claim 5
Dependent Claim
27 words
The combination as defined in claim 1 and further comprising a mounting bracket attached to said second member and to which said controller arm is hingedly connected.
Claim 6
Dependent Claim
50 words
The combination as defined in claim 4 wherein said mounting bracket has a rod extending between two laterally spaced portions thereof and wherein said controller arm is laterally slotted at said one end thereof to hingedly engage said rod while providing for relative lateral movement between the rod and arm.
Claim 7
Dependent Claim
43 words
The combination as defined in claim 5 and further comprising additional spring means connected between said mounting bracket and said controller arm for resiliently urging the controller arm to a position where the plot of the arm is fully engaged with said rod.
Claim 8
Dependent Claim
44 words
The combination as defined in claim 6 wherein the lower end of said controller arm is slotted throughout the width of said arm, said slotted portion being hingedly engaged with said rod and being resiliently urged in contact therewith by said additional spring means.
Claim 9
Dependent Claim
31 words
The combination as defined in claim 7 wherein said additional spring means comprises two springs each extending from one end of said rod to a corresponding side of said controller arm.
Claim 10
Dependent Claim
70 words
The combination as defined in claim 1 in which the first member is the boom of a crane, and in which the second member is a dipper stick which is slideably and pivotally connected thereto, and in which the hinged connection between the controller arm and dipper stick provides for pivotal movement of the arm toward the outer end of the dipper stick and toward a position of parallelism therewith.
Claim 11
Dependent Claim
73 words
The combination as claimed in claim 4 in which the mounting bracket has longitudinally spaced forward and rearward hinge projections, and in which the controller arm is hinged to said forward projections, and in which there is spring meAns connected between said rear projection and a projection from an upper portion of the arm, and in which a portion of the hose is guided between said arm and spring means toward said bracket.
Claim 12
Dependent Claim
70 words
The combination as defined in claim 5 in which the first member is the boom of a crane, and in which the second member is a dipper stick which is slideably and pivotally connected thereto, and in which the hinged connection between the controller arm and dipper stick provides for pivotal movement of the arm toward the outer end of the dipper stick and toward a position of parallelism therwith.
