Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
144 words
A wiper assembly comprising a frame member, said frame member including a central portion and connected side frame portions, a wiping pad disposed within said frame member with portions within each of said side frame portions, said side frame portions being pivotally engaged to said central portion and pivotal between an open position and a closed position wherein said wiping pad portions in said side frame portions substantially abut, mounting means including a mounting clip adaptable for engagement with a dip stick tube, said mounting means including shaft means adjustably engaged to said frame member whereby said wiping pad portions are positioned substantially adjacent to an open end of a dip stick tube and when said side frame portions are in said closed position said wiping pads contact and wipe a dip stick as the dip stick is withdrawn from the dip stick tube.
Claim 2
Dependent Claim
144 words
A wiper assembly comprising a frame member, said frame member including a central portion and connected side frame portions, a wiping pad disposed within said frame member with portions within each of said side frame portions, said side frame portions being pivotally engaged to said central portion and pivotal between an open position and a closed position wherein said wiping pad portions in said side frame portions substantially abut, mounting means including a mounting clip adaptable for engagement with a dip stick tube, said mounting means including shaft means adjustably engaged to said frame member whereby said wiping pad portions are positioned substantially adjacent to an open end of a dip stick tube and when said side frame portions are in said closed position said wiping pads contact and wipe a dip stick as the dip stick is withdrawn from the dip stick tube.

Claim 14
Independent Claim
224 words
A device for use in removing oil and other materials from a dip stick used to indicate fluid level in a crankcase or like device comprising: a. an open frame structure having a central portion and spaced connected side frame portions, the side frame portions being pivoted on the central portions between an open position spaced from each other and a closed position wherein the side frames are substantially adjacent one another, b. a fluid absorbent member positioned in the open frame and confined by the side frame portions, said absorbent member having side portions in the respective side frame portions and a portion that extends therebetween and across the central portion, c. means to mount said open frame adjacent to the open end of a dip stick tube whereby the side frame members can be moved to the closed position when the dip stick is withdrawn from the dip stick tube so that the fluids on the dip stick can be wiped from the dip stick, said mounting means including a clip portion adapted to resiliently engage the dip stick tube and an elongated member extending integrally from the clip portion, and d. means on the open frame for cooperative engagement with the elongated member to support the open frame in spaced relation adjacent to the open end of the dip stick tube.
