Abstract
Abstract A non threaded pipe connecting system for connecting pipe without the use of threads comprising; a first pipe member; a second pipe connector member having at least two slots formed therein and an inside diameter larger than the outside diameter of the first pipe member for receiving and snugly fitting about the outside diameter of the first pipe member; at least one o-ring mounted between the first and second pipe members for forming a seal therebetween and; a U-shaped clip member having generally parallel legs for being driven along the slots of the second pipe connector member on the outside of the second pipe member for sharply deforming the surface of the first pipe member on at least two sides and for forming an angle with said first pipe member along the sharply deformed area on the first pipe member for preventing the first pipe member from moving after insertion into the second pipe connector member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
163 words
A non-threaded pipe connector system for connecting pipe comprising: a first pipe member; a second pipe connector member having at least two opposed slots each formed tangentially through said second pipe member and having an inside diameter larger than the outside diameter of said first pipe member for receiving and snugly fitting about the outside diameter of said first pipe member; at least one o-ring seal means mounted between said first pipe member and said second pipe connector member for forming a seal therebetween and; a U-shaped clip means having generally parallel legs for being driven along said slots of said second pipe connector member on the outside of said second pipe connector member and for sharply deforming said first pipe member on at least two sides and for forming an angle with said first pipe member along the sharply deformed area on said first pipe member to prevent said first pipe member from moving after insertion into said second pipe connector member.
Claim 2
Dependent Claim
163 words
A non-threaded pipe connector system for connecting pipe comprising: a first pipe member; a second pipe connector member having at least two opposed slots each formed tangentially through said second pipe member and having an inside diameter larger than the outside diameter of said first pipe member for receiving and snugly fitting about the outside diameter of said first pipe member; at least one o-ring seal means mounted between said first pipe member and said second pipe connector member for forming a seal therebetween and; a U-shaped clip means having generally parallel legs for being driven along said slots of said second pipe connector member on the outside of said second pipe connector member and for sharply deforming said first pipe member on at least two sides and for forming an angle with said first pipe member along the sharply deformed area on said first pipe member to prevent said first pipe member from moving after insertion into said second pipe connector member.
Claim 3
Dependent Claim
51 words
A non-threaded pipe connector system for connecting pipe of claim 1 further comprising a stopping means for stopping and seating said first pipe member when said member is inserted into said second pipe member after said first pipe member has moved past said two slots in said second pipe connector member.
Claim 4
Dependent Claim
54 words
A non-threaded pipe connector system for connecting pipe of claim 2 further comprising a receiving chamber inside said inside diameter of said second pipe connector member formed for receiving said first pipe member and located between the entrance to said second pipe connector member and said stopping means within said second pipe connector member.
Claim 5
Dependent Claim
24 words
A non-threaded pipe connector system for connecting pipe of claim 3 wherein said at least one o-ring means is positioned within said receiving chamber.
Claim 6
Dependent Claim
64 words
A non-threaded pipe connector system for connecting pipe of claim 4 wherein said parallel legs of said U-shaped clip means further comprise a leading edge means on the tip of the inside edge of said U-shaped clip for gradually creasing the outside diameter of said first pipe member as said U-shaped clip means is driven along said slots of said second pipe connector member.
Claim 7
Dependent Claim
91 words
A non-threaded pipe connector system for connecting pipe of claim 5 wherein said parallel legs of said U-shaped clip means further comprise a deforming edge means proximate to said leading edge means and gradually changing from a leading edge means to a deforming edge means in moving from said tip of the inside edge of the U-shaped clip to the inside of the U-shaped clip for deforming said outside diameter of said first pipe member as said U-shaped clip means is driven along said slots of said second pipe connector member.
Claim 8
Dependent Claim
50 words
A non-threaded pipe connector system for connecting pipe of claim 6 wherein said deforming edge means is driven into place at substantially right angles to the direction of insertion of said first pipe member for preventing said first pipe member from moving after insertion into said second pipe connector member.
Claim 9
Dependent Claim
82 words
A non-threaded pipe connector system for connecting pipe of claim 7 wherein said outside bottom end of said U-shaped clip means forms a flat driving surface means for receiving blows to drive said clip in place and said flat driving surface means only extends over the open part of the inside of the U-shaped part of said U-shaped clip means for providing an even driving force to both legs and for prevention of deformation of one or the other of said legs.
Claim 10
Dependent Claim
48 words
A non-threaded pipe connector system for connecting pipe of claim 8 wherein said inside edge of said parallel legs of said U-shaped clip means are concaved sufficiently for forming a spring locking effect after they are driven over the apex of said first pipe member and into place.
Claim 11
Dependent Claim
40 words
A non-threaded pipe connector system for connecting pipe of claim 9 wherein said inside edge of said U-shaped clip means is curved to follow the contour of said outside surface of said second pipe member when against said outside surface.
Claim 12
Dependent Claim
55 words
A non-threaded pipe connector system for connecting pipe of claim 10 further comprising a nipple locking means on said leading edge of said parallel legs of said U-shaped clip means for engaging said outside diameter surface of said second pipe connector member after passing thereby when said U-shaped clip means is fully driven into place.
Claim 13
Dependent Claim
41 words
A non-threaded pipe connector system for connecting pipe of claim 11 wherein said at least two slots formed in said second pipe member have a cord length from 1/4 to 1/2 of the outside diameter of said second pipe connector means.
Claim 14
Dependent Claim
46 words
A non-threaded pipe connector system for connecting pipe of claim 12 wherein said first pipe member has a ratio of wall thickness to the outside diameter of said first pipe member of between 1 to 20 and from 1 to 50 for said first pipe member.
Claim 15
Dependent Claim
88 words
A non-threaded pipe connector system for connecting pipe of claim 13 wherein said bottom outside end of said U-shaped clip means further comprises a flat surface which is over the open inside portion of the U-shaped clip means and the sides of the bottom outside end of said U-shaped clip means are sloped surfaces over the width of said parallel legs of said U-shaped clip means for providing a means for transmitting even driving pressure along the inside surfaces of said parallel legs of said U-shaped clip means.
