Motor driven hose reel
First Claim
1. A reel assembly for carrying a flexible elongate member, said reel assembly comprising:
- a reel for connection to one end of the elongate member;
a frame rotatably supporting said reel;
an electric motor supported by said frame and rotatably driving said reel in a direction to retract the elongate member;
at least one sensor for sensing rotational movement of said reel; and
control means interconnecting said sensor and said motor for determining when said reel is rotated a first predetermined amount in a payout direction opposite the retraction direction and in response thereto actuating said motor to drive said reel in the retraction direction through sufficient rotation to completely rewind the elongate member, said control means further determining when said reel is rotated in said payout direction a second predetermined amount greater than said first predetermined amount and payout has stopped and actuating said motor to drive said reel in the retraction direction through a third predetermined amount less than that necessary to completely rewind the elongate member.

Abstract
A reel assembly for carrying a flexible elongate member. The reel assembly includes a reel for connection to one end of the elongate member, a frame rotatably supporting the reel, an electric motor supported by the frame and rotatably driving the reel in a direction to retract the elongate member, and at least one sensor for sensing rotational movement of the reel. A control device interconnecting the sensor and the motor determines when the reel is rotated a first predetermined amount in a payout direction opposite the retraction direction, and, in response thereto, actuates the motor to drive the reel in the retraction direction through sufficient rotation to be capable of completely rewinding the elongate member. The control device further determines when the reel is rotated in the payout direction a second predetermined amount greater than the first predetermined amount and actuates the motor to drive the reel in the retraction direction through a third predetermined amount less than that necessary to completely rewind the elongate member.

8. A reel assembly for carrying a flexible elongate member, said reel assembly comprising:
-
a reel for connection to one end of the elongate member; a frame rotatably supporting said reel; an electric motor supported by said frame and rotatably driving said reel; at least one sensor for sensing rotational movement of said reel; control means connected to said at least one sensor for determining when an end of elongate member payout condition occurs, said condition corresponding to a condition wherein the elongate member is no longer being unreeled from said reel and rotation of said reel has stopped; and means responsive to said end of payout condition for automatically actuating said motor to rewind said reel in a direction opposite said one direction in an amount less than that necesary to completely rewind said member. - View Dependent Claims (9, 10, 11, 12)
