Abstract
Abstract Apparatus for assisting in uncoiling and coiling a flexible hose, cord, or the like, in even layers on a fixed drum. The hose is uncoiled by pulling the free end in a direction more or less parallel to the axis of the drum on which it is coiled as an arm carrying a guide pulley rotates to follow the tangent of hose leaving the coil about the fixed drum. Springs tensioned by the uncoiling movement provide a biasing force for rewinding the hose, rotating the guide pulley and arm in the opposite direction. Novel motion transfer means are disclosed for producing traversing movement of the guide pulley along the length of the fixed drum as the arm carrying the pulley rotates thereby coiling the hose in even layers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
213 words
Apparatus for assisting in the coiling and uncoiling of an elongated, flexible element in a plurality of layers of side-byside revolutions of the element, said apparatus comprising, in combination: a. a fixed cylindrical element for receiving the coiled element on the outer periphery thereof; b. an elongated arm mounted for rotation about the central axis of said cylindrical element and arranged with its own axis transverse to said central axis; c. pulley means carried by said elongated arm and spaced radially from said outer periphery of said cylindrical element, and having an axis of rotation transverse to both said central axis and said arm axis, whereby the flexible element may extend tangentially from the coil, over said pulley means and substantially parallel to said central axis; d. spring means constructed and arranged to be tensioned by rotation of said arm in a first direction to exert a biasing force tending to rotate said arm in the opposite direction; e. mounting means allowing reciprocating traversing movement of said pulley means between positions radially spaced from each end of said cylindrical element; and f. motion transfer means for imparting a predetermined increment of said traversing movement to said pulley means in response to each revolution of said arm in either direction about said central axis.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
40 words
The invention according to claim 1 and further including a shaft mounted concentrically with and rotatable about said central axis, and means connecting said shaft and said arm to transmit rotation about said central axis from one to the other.
Claim 4
Dependent Claim
60 words
The invention according to claim 2 and further including means connecting said shaft to said spring means to transmit rotation of said arm in said first direction, through said shaft, to tensioning movement of said spring means, and to transmit the biasing force of said spring means through said shaft to tend to rotate said arm in said opposite direction.
Claim 5
Dependent Claim
37 words
The invention according to claim 3 wherein said mounting means comprises a hinged connection between said arm and said shaft allowing pivotal movement of said arm about an axis closely adjacent and transverse to said central axis.
Claim 6
Dependent Claim
33 words
The invention according to claim 4 wherein said motion transfer means comprises mechanism responsive to rotation of said arm in either direction to transmit motion thereto about the axis of said hinged connection.
Claim 7
Dependent Claim
26 words
The invention according to claim 5 wherein said mechanism comprises an eccentric member rotatable about an axis substantially parallel to the axis of said hinged connection.
Claim 8
Dependent Claim
49 words
The invention according to claim 2 and further including a second arm connected to said shaft for rotation therewith, said motion transfer means being connected between said second arm and said elongated arm to impart to the latter movement providing said traversing movement of said pulley means carried thereby.
Claim 9
Dependent Claim
26 words
The invention according to claim 7 wherein said second arm is mounted for rotation about its own axis in response to rotation about said central axis.
Claim 10
Dependent Claim
50 words
The invention according to claim 8 wherein said motion transfer means comprises a worm gear carried by said second arm and rotatable about the axis thereof, and said elongated arm carries an eccentric gear meshed with said worm gear and rotatable thereby to impart said movement to said elongated arm.
Claim 11
Dependent Claim
19 words
The invention according to claim 1 wherein said pulley means comprises a pulley wheel having two grooves arranged side-by-side.
