Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A pipe coupler for connecting a pipe through a casing to a line comprising: a. a first coupler member having on one side thereof a vertical trackway with two open ends; b. a bore extending through said first coupler member for communicating said pipe to said line; c. a second coupler member having a plate formed thereon and adapted for sliding movement in said trackway through either open end thereof; and d. a stop formed on said plate to limit the movement of said plate through said trackway.
Claim 2
Dependent Claim
88 words
A pipe coupler for connecting a pipe through a casing to a line comprising: a. a first coupler member having on one side thereof a vertical trackway with two open ends; b. a bore extending through said first coupler member for communicating said pipe to said line; c. a second coupler member having a plate formed thereon and adapted for sliding movement in said trackway through either open end thereof; and d. a stop formed on said plate to limit the movement of said plate through said trackway.
Claim 3
Dependent Claim
18 words
A device as claimed in claim 1, wherein said plate is formed of uniform thickness and uniform width.
Claim 4
Dependent Claim
19 words
A device as claimed in claim 1, wherein said trackway comprises two parallel tracks of uniform width and breadth.
Claim 5
Dependent Claim
35 words
A device as claimed in claim 1, wherein sealing means is provided on said plate for sealing engagement with said first coupler section for sealing the connection between said plate and said first coupler section.
Claim 6
Independent Claim
145 words
The method of attaching to a bore in a casing, at least one section of a two-section coupling of the type wherein the first section includes a nipple extending from a body and a trackway extending vertically on the opposite side of the body with a uniform width and breadth and a second section including a body having a uniform thickness plate integrally secured thereto with a stop formed at one end thereof including the steps of: a. assembling the first section onto the second section with the second section inverted to position the stop at the lower end thereof in supporting relation to the first section; b. attaching a handle to said second section for jointly manipulating said first and second section; c. lowering said sections into said casing; and d. manipulating the coupling to project the nipple through said bore in the casing.
Claim 7
Independent Claim
145 words
The method of attaching to a bore in a casing, at least one section of a two-section coupling of the type wherein the first section includes a nipple extending from a body and a trackway extending vertically on the opposite side of the body with a uniform width and breadth and a second section including a body having a uniform thickness plate integrally secured thereto with a stop formed at one end thereof including the steps of: a. assembling the first section onto the second section with the second section inverted to position the stop at the lower end thereof in supporting relation to the first section; b. attaching a handle to said second section for jointly manipulating said first and second section; c. lowering said sections into said casing; and d. manipulating the coupling to project the nipple through said bore in the casing.
Claim 8
Dependent Claim
32 words
The method set forth in claim 5, further including the steps of: a. securing the nipple to the casing; and b. lowering the second section to disengage it from the first section.
Claim 9
Dependent Claim
55 words
The method set forth in claim 6, further including the steps of: a. inverting the second section and securing it to a handle; and b. lowering the second section to position the plate in the trackway with the stop engaging the top of the first section to support said second section on said first section.
Claim 10
Dependent Claim
40 words
The method as claimed in claim 4, wherein the step of assembling said plate in said trackway with said stop engaging the top of said first section includes the step of sealing said first Section and said second section together.
