Takeup reel for combined hose and cable

A takeup reel for combined hydraulic hose and electrical cable comprising

• a mounting member,
• a rotary storage portion for taking up and paying out such hose and cable mounted for rotation on said mounting member,
• biasing spring disposed axially to one side of said storage portion and acting between the same and said mounting member for urging relative rotation between the two in one direction,
• a housing for said spring joined to and projecting axially away from said one side of said storage portion,
• interface cable means for accommodating a brushless, electrical connection between cable stored on said storage portion and an external supply of electrical power, said interface cable means including a portion disposed as a spiral winding about said mounting member on the opposite side of said spring housing from said storage portion, and
• a housing for said portion of said interface cable means joined for rotation as a unit with said storage portion and said spring housing, and including a space containing said interface cable means portion which space is disposed on said opposite side of said spring housing.

In a takeup reel for combined hydraulic hose and electrical cable which reel includes a biasing spring having a coiled portion for accommodating a brushless electrical connection between cable stored by the reel and an external supply of electrical power:

• a mounting member extending along the rotational axis of the reel;
• and
• an axially compact sandwich assembly mounted for rotation on said mounting member, said sandwich assembly including a rotary storage portion for taking up and paying out such hose and cable,
• a housing for said coiled portion of said spring joined to and projecting axially away from one side of said storage portion, and
• a housing for said coiled portion of said interface cable joined for rotation as a unit with said storage portion and said spring housing, and projecting axially away from the side of said spring housing which is opposite said one side of storage portion.

In a takeup reel for a multiple-element line, where the reel includes a rotary line-storing portion, and a mounting member mounting the line-storing portion for rotation thereon and relative thereto and accommodating attachment of the reel to an external structure, means affording an operative connection between the elements in a line stored on said line-storing portion and structure external to the reel, said means comprising

• an elongated multiple-element interface line including a different element for each element in a line stored on said line-storing portion, said interface line including one stretch wherein its said elements are joined in substantial side-by-side contiguity to have a flat ribbon-like configuration, and another stretch joined to said one stretch wherein its said elements take the form of a loose nonjoined bundle,
• means defining a generally circular storage space on said reel to one side of said line-storing portion for storing a flat spiral winding of said one stretch of said interface line, which winding lies in a plane generally paralleling that in which line is stored on said line-storing portion,
• means defining a passage in said mounting member for receiving said other stretch of said interface line, said passage extending generally parallel to the rotational axis provided by the mounting member for the line-storing portion, and having an end communicating with said storage space, and
• strain-relief guide means attached to said interface line at the region of joinder of said one and other stretches, said guide means being mounted for limited rotation on said mounting member about an axis substantially paralleling the rotational axis of said line-storing portion, said guide means guiding said one stretch of said interface line into said storage space in said first-mentioned plane, and further guiding said other stretch of said interface line into said passage.

A take-up reel for line including electrical conductors comprising

• a mounting member,
• a rotary storage portion for taking up and paying out such line mounted for rotation on said mounting member,
• a biasing spring disposed axially to one side of said storage portion and acting between the same and said mounting member for urging relative rotation between the two in one direction,
• a housing for said spring joined to and projecting axially away from said one side of said storage portion,
• interface cable means for accommodating a brushless, electrical connection between electrical conductors in line stored on said storage portion and an external supply of electrical power, said interface cable means including a portion disposed as a spiral winding about said mounting member on the opposite side of said spring housing from said storage portion, and
• a housing for said portion of said interface cable means joined for rotation as a unit which said storage portion and said spring housing, and including a space containing said interface cable means portion which space is disposed on said opposite side of said spring housing.
