Abstract
Abstract A method and device for everting thin-walled flexible tubular casings or the like by passing a distal portion of the casing through a ring member, folding the casing back over the ring, grasping the free end of the casing, and displacing the ring relative to the fixed casing end, whereby the casing is drawn through and around the ring and is thereby everted.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
A device for everting a thin-walled flexible tubular casing or the like, comprising a support frame, clamping means mounted on the frame for gripping a distal end portion of an everted portion of the casing, a ring for placement in a looop formed by a juncture between said everted portion and a following noneverted portion attendant to said portions being telescoped with respect to each other, and means external of said casing for displacing said ring relative to said clamping means lengthwise of the casing for thus everting said noneverted portion of the casing.
Claim 2
Independent Claim
94 words
A device for everting a thin-walled flexible tubular casing or the like, comprising a support frame, clamping means mounted on the frame for gripping a distal end portion of an everted portion of the casing, a ring for placement in a looop formed by a juncture between said everted portion and a following noneverted portion attendant to said portions being telescoped with respect to each other, and means external of said casing for displacing said ring relative to said clamping means lengthwise of the casing for thus everting said noneverted portion of the casing.
Claim 3
Independent Claim
84 words
A device for everting a thin-walled flexible tubular casing or the like comprising a frame, clamping means for gripping a distal end portion of an everted portion of the casing, a ring for placement in a loop comprising the juncture between said everted portion and a following noneverted portion, and means for displacing said ring relative to said clamping means, whereby said noneverted portion of the casing is everted, wherein said displacing means includes means for coupling said ring through said loop of casing.
Claim 4
Independent Claim
84 words
A device for everting a thin-walled flexible tubular casing or the like comprising a frame, clamping means for gripping a distal end portion of an everted portion of the casing, a ring for placement in a loop comprising the juncture between said everted portion and a following noneverted portion, and means for displacing said ring relative to said clamping means, whereby said noneverted portion of the casing is everted, wherein said displacing means includes means for coupling said ring through said loop of casing.
Claim 5
Dependent Claim
41 words
The invention of claim 2, wherein said ring includes magnetic material, and said displacing means includes a magnet adapted to attract said ring and maintain the same in close relation therewith, whereby said ring may be displaced by displacing said magnet.
Claim 6
Dependent Claim
26 words
The invention of claim 3, wherein said ring and said displacing means each include means for reducing the drag force on a casing being drawn therebetween.
Claim 7
Dependent Claim
29 words
The invention of claim 4, wherein said displacing means includes a track and a motor, said magnet being mounted on said track and being driven therealong by said motor.
Claim 8
Dependent Claim
35 words
The invention of claim 4, wherein said drag-reducing means on said displacing means and said ring comprise a plurality of mating rotatable members disposed in the opposing faces of said ring and said displacing means.
Claim 9
Independent Claim
80 words
A device for everting a thin-walled flexible tubular casing or the like, comprising a toroidal ring member about which a distal end portion of casing may be everted, a clamp for securing the distal end of said everted portion of casing, means for displacing said ring member relative to said clamp for drawing said casing through the ring and thereby everting said casing, and means for holding said ring through said casing in operative relation to said means for displacing.
Claim 10
Independent Claim
80 words
A device for everting a thin-walled flexible tubular casing or the like, comprising a toroidal ring member about which a distal end portion of casing may be everted, a clamp for securing the distal end of said everted portion of casing, means for displacing said ring member relative to said clamp for drawing said casing through the ring and thereby everting said casing, and means for holding said ring through said casing in operative relation to said means for displacing.
Claim 11
Independent Claim
82 words
A device for everting a thin-walled flexible tubular casing or the like, comprising a frame, a toroidal ring member about which a distal end portion of casing may be everted, a clamp for securing the distal end of said everted portion of casing, and means on the frame for displacing said ring member relative to said clamp, whereby the casing is drawn through the ring and thereby everted, wherein said displacement means comprises a movable member magnetically coupleable to said ring member.
Claim 12
Independent Claim
82 words
A device for everting a thin-walled flexible tubular casing or the like, comprising a frame, a toroidal ring member about which a distal end portion of casing may be everted, a clamp for securing the distal end of said everted portion of casing, and means on the frame for displacing said ring member relative to said clamp, whereby the casing is drawn through the ring and thereby everted, wherein said displacement means comprises a movable member magnetically coupleable to said ring member.
Claim 13
Dependent Claim
32 words
The device of claim 8 wherein said ring member and said movable member comprise facing surfaces, and means on said surfaces for reducing drag forces impressed on the casing being drawn therebetween.
Claim 14
Independent Claim
92 words
A method of everting a length of thin-walled flexible tubular casing or the like, comprising the steps of: a. everting a distal portion of the casing around a ring by passing the casing solely through the ring and telescoping an everted outer portion of the casing about an inner portion thereof; b. gripping the distal end of said everted portion of casing; and c. displacing said ring relative to said distal end of the casing and thereby drawing the inner portion of the casing through said ring and thus everting the casing.
Claim 15
Independent Claim
92 words
A method of everting a length of thin-walled flexible tubular casing or the like, comprising the steps of: a. everting a distal portion of the casing around a ring by passing the casing solely through the ring and telescoping an everted outer portion of the casing about an inner portion thereof; b. gripping the distal end of said everted portion of casing; and c. displacing said ring relative to said distal end of the casing and thereby drawing the inner portion of the casing through said ring and thus everting the casing.
Claim 16
Independent Claim
82 words
A method of everting a length of thin-walled flexible tubular casing or the like, comprising the steps of; a. everting a distal portion of the casing around a ring; b. gripping the distal end of said everted portion of casing; and c. displacing said ring relative to said distal end of the casing, whereby the casing is drawn through said ring and thereby everted, and said ring is displaced by magnetically coupling the same to a movable member exterior to said casing.
Claim 17
Independent Claim
82 words
A method of everting a length of thin-walled flexible tubular casing or the like, comprising the steps of; a. everting a distal portion of the casing around a ring; b. gripping the distal end of said everted portion of casing; and c. displacing said ring relative to said distal end of the casing, whereby the casing is drawn through said ring and thereby everted, and said ring is displaced by magnetically coupling the same to a movable member exterior to said casing.
