Abstract
Abstract Valve having provision to cut its own installation hole so that the valve can be installed in an existing pipe line without removing the pipe line from service. A cutting tool is provided at an end of the valve apparatus, and motors are provided which move the cutting tool both rotationally and axially to cut a valve installation hole in the pipe. Provision is made for sealing the valve seat after the hole has been cut and the valve seat positioned, and for removing the cutting tool if desired. Once the installation is completed, the axial edn rotational motive apparatus can be removed and replaced with conventional valve actuating apparatus.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
Valve apparatus for installation on a pipe, comprising in combination: valve housing means defining a pipe passageway through which the pipe may be received; pipe cutting means received within said valve housing means in communication with said passageway and selectively operative to bore a valve receiving aperture in the pipe; valve seat means disposed within said valve housing means, said valve seat means including a fluid passage therethrough and being selectively operative to be moved through the aperture provided by said pipe cutting means to dispose said fluid passage into substantial alignment with the pipe; and valve member means disposed within said valve housing means and selectively operative to be disposed within said valve seat means in fluid flow blocking relation with said fluid passage therethrough, whereby to obstruct the flow of fluid through the pipe, and to be disposed in said fluid passage, whereby to permit fluid flow through the pipe.
Claim 2
Dependent Claim
152 words
Valve apparatus for installation on a pipe, comprising in combination: valve housing means defining a pipe passageway through which the pipe may be received; pipe cutting means received within said valve housing means in communication with said passageway and selectively operative to bore a valve receiving aperture in the pipe; valve seat means disposed within said valve housing means, said valve seat means including a fluid passage therethrough and being selectively operative to be moved through the aperture provided by said pipe cutting means to dispose said fluid passage into substantial alignment with the pipe; and valve member means disposed within said valve housing means and selectively operative to be disposed within said valve seat means in fluid flow blocking relation with said fluid passage therethrough, whereby to obstruct the flow of fluid through the pipe, and to be disposed in said fluid passage, whereby to permit fluid flow through the pipe.
Claim 3
Dependent Claim
65 words
Valve apparatus as in claim 1, wherein: said valve housing means includes a valve passageway disposed in communication with said pipe passageway; said pipe cutting means being received within said valve passageway and being selectively movable to extend from the valve passageway into cutting engagement with the pipe, and further comprising: first motive means for urging said pipe cutting means into engagement with the pipe.
Claim 4
Dependent Claim
48 words
Apparatus as in claim 2, wherein said pipe cutting means comprising rotary cutting means received within said valve passageway to be axially moved into cutting engagement with the pipe, and further comprising second motive means operatively connected to said rotary cutting means for imparting pipe cutting rotation thereto.
Claim 5
Dependent Claim
81 words
Apparatus as in claim 1, further comprising: a valve passageway disposed within said valve housing means to intersect said pipe passageway; said valve seat means being movably received within said valve passageway to be selectively displaceable from a first position in which said valve seat means is completely withdrawn from said pipe opening to a second position in which said valve seat means is disposed in said pipe opening; and means for retaining said valve seat means in said second position.
Claim 6
Dependent Claim
92 words
Apparatus as in claim 4, further comprising: said valve seat means having a valve member recess extending therethrough in intersecting relationship with said fluid passage of said valve seat means; said valve member means being configured to be receivable within said valve member recess; said pipe cutting means being attached to The end of said valve member means which is proximal to said pipe passageway; and, first motive means for axially displacing said valve means, said valve seat means, and said pipe cutting means along said valve passageway toward said pipe passageway.
Claim 7
Dependent Claim
86 words
Apparatus as in claim 5, wherein: said valve member means is rotatably received within said valve member recess of said valve seat means, and further comprising: second motive means operatively connected to said valve member means to selectively impart rotational motion thereto; rotation restraining means operatively interrelated between said valve seat means and said valve passageway to prevent rotation of said valve seat means while permitting axial movement of said valve seat means along said valve passageway responsive to the operation of said first motive means.
Claim 8
Dependent Claim
92 words
Apparatus as in claim 6, wherein: said retaining means includes a first recess disposed on the exterior of said valve seat means; locking means disposed within said first recess to be urged outwardly therefrom; and a second recess means disposed within said valve passageway to be in alignment with said first recess means and said locking means disposed therein when said valve seat has been displaced to said second position, whereby said locking means engages said second recess means to cause said valve seat means to be retained in said second position.
Claim 9
Dependent Claim
51 words
Apparatus as in claim 6 wherein at least said first motive means is detachably operatively engaged to impart displacement motion to said valve member means so that a valve member actuation means may be operatively associated with said valve member means after said valve seat means has become retained in position.
Claim 10
Dependent Claim
76 words
Apparatus as in claim 6 wherein said pipe cutting means includes a first rotary cutting portion for producing in the pipe a pilot hole which is substantially smaller than the pipe aperture required to accommodate entry of said valve seat means, said pipe cutting means further comprising a hold enlargement portion to be received within the pilot hole and to enlarge the pilot hole to the extent necessary to accommodate entry of said valve seat means.
Claim 11
Dependent Claim
58 words
Apparatus as in claim 6, further comprising at least one sealant receiving receptacle disposed on the exterior of said valve seat, and at least one corresponding sealant applying means associated with said valve housing means in position to establish sealant applying relationship with said sealant recess means when said valve seat means is retained in the locked position.
