Abstract A dip stick wiper attachment for the conventional dip stick guide pipe of a liquid reservoir, consisting essentially of a tubular pliant wiper member having a first portion slipped over the upper end of the guide pipe, a cup portion of large internal diameter extending above the pipe and a shoulder between said portions located at approximately the upper end of the pipe, and a hose clamp securing said first portion to the pipe. The pliant cup is manually squeezable into engagement with the dip stick as it is withdrawn from the reservoir to wipe the stick clean, and upon release flexes outwardly to accommodate normal unrestricted subsequent passage of the dip stick through the pipe to and from the reservoir for purposes of liquid level measurement. The pliant cup is always at hand to serve a wiping function and it insures automatic return to the reservoir of the fluid wiped from the stick. Also, by virtue of its large diameter, the cup accommodates the normal appurtenances on the upper end of the dip stick so that no change is required in either the dip stick or the guide pipe originally supplied with the reservoir.

Total Claims: 6
Claim 1
Independent Claim
222 words
A wiper for the dip stick of a liquid reservoir having a dip stick guide pipe, consisting essentially of a tubular pliant wiper member comprising a first tubular portion of an inner diameter approximately equal to the outer diameter of the guide pipe adapted to be pliantly and adjustably telescoped over the upper end of the guide pipe for sealing engagement therewith, a cup portion of a substantially larger inner diameter adapted to extend upwardly above the guide pipe and a shoulder between said portions adapted to be located at approximately the upper end of the guide pipe, said cup portion being nonfibrous, essentially nonabsorbent and squeezable between the thumb and finger of an operator into wiping contact with the dip stick as the latter is removed from the guide pipe and normally flexing itself outwardly to accommodate unobstructed passage of the dip stick, said cup portion catching the liquid wiped from the dip stick and said shoulder directing the liquid back into the guide pipe, said cup portion accommodating the upper extremities of the dip stick and said shoulder accommodating normal engagement of the dip stick in the guide pipe whereby neither the dip stick nor the guide pipe requires replacement or modification, and a hose clamp around said first tubular portion for sealingly securing the wiper to the guide pipe.
Claim 2
Dependent Claim

A wiper for the dip stick of a liquid reservoir having a dip stick guide pipe, consisting essentially of a tubular pliant wiper member comprising a first tubular portion of an inner diameter approximately equal to the outer diameter of the guide pipe adapted to be pliantly and adjustably telescoped over the upper end of the guide pipe for sealing engagement therewith, a cup portion of a substantially larger inner diameter adapted to extend upwardly above the guide pipe and a shoulder between said portions adapted to be located at approximately the upper end of the guide pipe, said cup portion being nonfibrous, essentially nonabsorbent and squeezable between the thumb and finger of an operator into wiping contact with the dip stick as the latter is removed from the guide pipe and normally flexing itself outwardly to accommodate unobstructed passage of the dip stick, said cup portion catching the liquid wiped from the dip stick and said shoulder directing the liquid back into the guide pipe, said cup portion accommodating the upper extremities of the dip stick and said shoulder accommodating normal engagement of the dip stick in the guide pipe whereby neither the dip stick nor the guide pipe requires replacement or modification, and a hose clamp around said first tubular portion for sealingly securing the wiper to the guide pipe.
Claim 3
Dependent Claim
14 words
The wiper of claim 1 wherein the wiper member is a unitary molded element.
Claim 4
Dependent Claim
49 words
The wiper of claim 1 wherein said first tubular portion comprises a first tube, said cup portion comprises a second tube telescoped over said first tube and said clamp encircles the lower end of said second tube for sealingly securing said tubes to one another and the guide pipe.
Claim 5
Dependent Claim
27 words
The wiper of claim 1 wherein said cup portion is provided with external surface irregularities to facilitate grasping of the same and performance of the wiping function.
Claim 6
Dependent Claim
20 words
The wiper of claim 1 wherein said shoulder slopes inwardly and downwardly toward the upper end of the guide pipe.
