Abstract
Abstract A removably mounted probe provides access to a fluid enclosure. The front end of the probe has a collar which seats on a beveled shoulder to position the probe relative to the fluid enclosure. The back end of the probe extends through a ball valve and a pair of fittings positioned end-to-end which are held together by a snap coupling. The collar acts to dampen backward movement of the probe when it is released and finally abuts the fittings which limit the probe's movement. The ball valve is closed and the snap coupling removed. The probe may now be fully removed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A mounting for removably introducing a probe into a fluid enclosure, said mounting including a boss having a bore and a counter bore forming a positioning shoulder therebetween and penetrating said enclosure, a valve connected to said boss, and an extension pipe connected to said valve, comprising: a removable housing in fluid tight end-to-end relation with said pipe and having a bore of lesser diameter than the internal diameter of said pipe to form a retaining shoulder therebetween, coupling means to secure said pipe and said housing in said end-to-end relationship, said housing, said pipe, said valve and said boss forming a continuous passageway for said probe into said enclosure, said probe having a collar continguous one end for seating on said positioning shoulder or abutting said retaining shoulder, and means for maintaining said probe collar seated on said positioning shoulder.
Claim 2
Dependent Claim
141 words
A mounting for removably introducing a probe into a fluid enclosure, said mounting including a boss having a bore and a counter bore forming a positioning shoulder therebetween and penetrating said enclosure, a valve connected to said boss, and an extension pipe connected to said valve, comprising: a removable housing in fluid tight end-to-end relation with said pipe and having a bore of lesser diameter than the internal diameter of said pipe to form a retaining shoulder therebetween, coupling means to secure said pipe and said housing in said end-to-end relationship, said housing, said pipe, said valve and said boss forming a continuous passageway for said probe into said enclosure, said probe having a collar continguous one end for seating on said positioning shoulder or abutting said retaining shoulder, and means for maintaining said probe collar seated on said positioning shoulder.
Claim 3
Dependent Claim
19 words
A mounting for a probe according to claim 1 wherein said positioning shoulder is beveled to position said probe.
Claim 4
Dependent Claim
22 words
A mounting for a probe according to claim 2 which also includes a fluid-tight seal for said probe mounted in said housing.
Claim 5
Dependent Claim
43 words
A mounting for a probe according to claim 3 which also includes: a safety housing to prevent access to said coupling means, said valve having a handle which when open locks said safety housing in position to prevent access to said coupling means.
Claim 6
Dependent Claim
24 words
A mounting for a probe according to claim 4 wherein said coupling means is a snap coupling for easy removal of said removable housing.
Claim 7
Dependent Claim
38 words
A mounting for a probe according to claim 5 wherein said collar has a close fit within said passageway to restrict rapid passage of fluid around said collar, thereby to dampen movement of said probe through said passageway.
Claim 8
Dependent Claim
53 words
A mounting for a probe according to claim 1 wherein said retaining means includes a bushing secured in said housing bore, the other end of said probe having a step portion for engaging said bushing such that said bushing retains said probe within said passageway with said collar seated on said positioning shoulder.
Claim 9
Dependent Claim
43 words
A mounting for a probe according to claim 1 which also includes: a safety housing to prevent access to said coupling means, said valve having a handle which when open locks said safety housing in position to prevent access to said coupling means.
