Abstract
A pipe saddle for providing a reliable connection to a pipe. The present invention uses a barb seal which embeds within the surface of the pipe to lock the pipe saddle in place and prevent leakage. The barb seal is formed from the material of the pipe saddle so that no deterioration occurs. The barb seal has an oval shape to provide better sealing capabilities. T-bolt connectors allow the device to be individually tightened on each side of the pipe while allowing the body portions of the saddle to be pivotally opened yet maintained as a single unit to allow easy implementation.
Claims12
A pipe saddle for mounting on a pipe, said pipe saddle including:
- first body portion means extending along a first longitudinal axis and having an arcuate inner surface,
- first and second flange members respectively connected to said first body portion means on substantially opposite sides of said first body portion means relative to said first longitudinal axis,
- second body portion means extending along a second longitudinal axis and having an arcuate inner surface,
- third and fourth flange members respectively connected to said second body portion means on substantially opposite sides of said second body portion means relative to said second longitudinal axis,
- first connector means including first retainer means extending along a first retainer axis between said first and third flange members to pivotally mount said first and second body portion means together for pivotal movement about a first pivotal axis, said first pivotal axis being fixed relative to one of said first and third flange members and substantially parallel to and fixed relative to at least one of said first and second longitudinal axes of said first and second body portion means, said first connector means further including means for selectively drawing said first and third flange members toward each other along said first retainer axis, said retainer axis being substantially perpendicular to said one of said first and second longitudinal axes of said first and second body portion means, said first connector means further including means for maintaining said first and second body portion means together as a singletary unit as said first and second body portions are pivotally moved relative to each other about said first pivotal axis, and
- second connector means including second retainer means extending along a second retainer axis and means for pivotally mounting said second retainer means to one of said second and fourth flange members for pivotal movement about a second pivotal axis, said second pivotal axis being fixed relative to one of said second and fourth flange members and substantially parallel to and fixed relative to at least one of said first and second longitudinal axes of said first and second body portion means, the other of said second and fourth flange members including an open slot for selectively receiving said second retainer means as said second retainer means is pivoted about said second pivotal axis, said second connector means further including means for selectively drawing said second and fourth toward each other along said second retainer axis when said second retainer means is received in said open slot wherein said first and second body portion means of said pipe saddle can be opened relative to each other and placed about the pipe by being pivotally moved relative to each other about said first pivotal axis with said second retainer means pivoted about said second pivotal axis and disengaged from receipt in said open slot and whereby said first and second body portion means can be selectively tightened on said pipe by pivoting said second retainer means about said second pivotal axis to be received in said open slot and then said first and second retainer means selectively and individually tightened to respectively draw said first and third flange members toward each other and to draw said second and fourth flange members toward each other.

A pipe saddle for mounting on a pipe, said pipe saddle including:
- first body portion means extending along a first longitudinal axis and having an arcuate inner surface,
- first and second flexible members respectively connected to said first body portion means on substantially opposite sides of said first body portion means relative to said first longitudinal axis,
- second body portion means extending along a second longitudinal axis and having an arcuate inner surface,
- third and fourth flexible flange members respectively connected to said second body portion means on substantially opposite sides of said second body portion means relative to said second longitudinal axis,
- first connector means including first retainer means extending along a first retainer axis between said first and third flange members, said first and third flange members have respective surfaces facing one another and said first connector means further including means for selectively drawing said first and third flange members and said facing surfaces thereof toward each other,
- second connector means including second retainer means extending between said second and fourth flange members, and
- said facing surface of said first flange member having a portion extending outwardly of said first retainer axis relative to said first body portion means and said facing surface of said third flange member having a portion extending outwardly of said first retainer axis relative to said second body portion means, one of said portions of said facing surfaces having at least one protuberance thereon extending beyond said one facing surface toward the other facing surface, said portion of said other facing surface contacting said protuberance as said first and third flange members are drawn together so that in one mode of operation with the second and fourth flange members spaced apart from each other and the first and second body portion means also spaced apart from each other, said protuberance serves as a pivot to cause said first and third flange members to pivot about said protuberance as said retaining means further draws the first and third flange members together to cause said second and fourth flange members and said first and second body portion means to pivot closer together about said protuberance and so that in a second mode of operation with the second and fourth flange members contacting one another and said first and second body portion means spaced apart from each other, said protuberance serves as a pivot to cause said first and third flange members to flex and pivot about said protuberance as said retaining means further draws the first and third flange members together to cause said first and second body portion means to pivot closer together about said protuberance.

A pipe saddle for mounting on a cylindrical pipe, said pipe saddle including:
- first body portion means extending along a longitudinal axis and having an arcuate inner surface substantially corresponding to the outer surface of said cylindrical pipe,
- barb seal means disposed on said inner arcuate surface and integrally formed from a portion of said first body portion means to prevent deterioration and movement of said barb seal means relative to said first body portion means and the arcuate inner surface thereof, said barb seal means extending about a first axis substantially perpendicular to said longitudinal axis and being composed of a single knife edge extending about said first axis and facing substantially in the direction of said first axis away from said arcuate inner surface and toward the outer surface of said pipe, said single knife edge extending continuously about said first axis to form a closed loop, and
- attaching means extending entirely outside of said pipe for selectively mounting said first body portion means on said pipe without having any portion of said attaching means extending into the interior of said pipe to obstruct the flow through the pipe, said attaching means including means for drawing said arcuate inner surface toward said outer pipe surface with said knife edge of said barb seal means contacting said outer pipe surface and penetrating into said pipe to become embedded therein to anchor said first body portion means on said pipe and create a seal between said pipe and said first body portion means.
