Abstract
Abstract A dip stick assembly with a tubular body having an internal ledge of a fixed position and a cup-shaped external opened end with a closure cap adapted to close the end, the closure cap having an axial groove receiving the cup-shaped opening of the tubular body, a dip stick fastened to the cap, a bayonet connection between the cap and the body allowing axial movement of the cap with respect to the body, the dip stick having a spring means around the upper portion thereof, the spring means contacting a radial projection member on the dip stick axially movable thereon, the radial projection adapted to contact the internal ledge on the body wherein the spring will force the cap away from the body to maintain the dip stick normally at a given level while depressing the cap towards the body will move the dip stick axially within the body to a measuring level, the spring cooperating with the bayonet lock to maintain the cap securely fastened to the body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
342 words
A dip stick assembly comprising: a body portion; said body portion including an elongated tube of axially varying diameter having an inlet end, said inlet end having a circumferential peripheral wall and an open end formed by said wall, a cap portion, said cap portion substantially cup-shaped having a peripheral circumferential wall with an open end defined by portions of said wall, an annular axially extending groove in the cap peripheral wall extending from the open end, said groove dimensioned to receive portions of the circumferential peripheral wall of the inlet end, a dip stick fixedly attached to said cap depending therefrom and projecting from the open end and dimensioned to extend through the body portion when the cap is received around the inlet end peripheral wall of the body portion, and seal means in the groove engaging the inlet and peripheral wall, said body portion has an internal ledge intermediate the ends thereof and the said sip stick has a radial abutment member slidably received therearound and freed for axial movement over at least a portion of the said axial length of the dip stick, the said radial abutment member having an outer diameter greater than the inner diameter of the said internal ledge of the said body portion, and a spring means around the said dip stick entrapped between a portion of the said cap and the said radial abutment urging the said radial abutment away from the said cap whereby when the said radial abutment is abutted against the said internal ledge of the said body, the said spring urges the said cap away from the said body, an axially extending slot and pin assembly, one of said slot and pin assembly being located on said cap and the other of said slot and pin assembly being located on said body, said pin being slidable in said slot to guide the raising and lowering of said cap and dipstick relative to said body, and means on said cap for locking said pin in said slot in an elevated position.
Claim 2
Dependent Claim
342 words
A dip stick assembly comprising: a body portion; said body portion including an elongated tube of axially varying diameter having an inlet end, said inlet end having a circumferential peripheral wall and an open end formed by said wall, a cap portion, said cap portion substantially cup-shaped having a peripheral circumferential wall with an open end defined by portions of said wall, an annular axially extending groove in the cap peripheral wall extending from the open end, said groove dimensioned to receive portions of the circumferential peripheral wall of the inlet end, a dip stick fixedly attached to said cap depending therefrom and projecting from the open end and dimensioned to extend through the body portion when the cap is received around the inlet end peripheral wall of the body portion, and seal means in the groove engaging the inlet and peripheral wall, said body portion has an internal ledge intermediate the ends thereof and the said sip stick has a radial abutment member slidably received therearound and freed for axial movement over at least a portion of the said axial length of the dip stick, the said radial abutment member having an outer diameter greater than the inner diameter of the said internal ledge of the said body portion, and a spring means around the said dip stick entrapped between a portion of the said cap and the said radial abutment urging the said radial abutment away from the said cap whereby when the said radial abutment is abutted against the said internal ledge of the said body, the said spring urges the said cap away from the said body, an axially extending slot and pin assembly, one of said slot and pin assembly being located on said cap and the other of said slot and pin assembly being located on said body, said pin being slidable in said slot to guide the raising and lowering of said cap and dipstick relative to said body, and means on said cap for locking said pin in said slot in an elevated position.
Claim 3
Dependent Claim
64 words
The assembly of claim 1 wherein the locking means includes a bayonEt slot including a locking slot and pin assembly between the said inlet end peripheral wall and the said cap, the locking slot of the said bayonet slot extending axially whereby axial movement of the said cap with respect to the said body is limited by the said bayonet slot and pin assembly.
Claim 4
Dependent Claim
54 words
The assembly of claim 2 wherein the said body has an external radially projecting ledge intermediate the ends thereof, the said ledge adapted to abut the periphery of a housing opening into which the said body is received to dimension the said body at a specified point with respect to the said housing opening.
Claim 5
Dependent Claim
23 words
The assembly of claim 2 wherein the said dip stick has a radial abutment thereon limiting movement of the said radially projecting member.
Claim 6
Dependent Claim
