Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
A device for squeezing a liquid carrying sheet material comprising a roller rotatable about a fixed horizontal axis, means for driving said roller, a resilient leaf member supported at the lower end thereof beneath said roller and having an upper end portion in pressure contact with the lower surface of the roller, sheet material being directed between the roller and the leaf member and being moved by contact with said roller, the upper end of the leaf member being directed rearwardly with respect to the advance of said sheet material passing between the roller and the leaf member, and the upper end portion of said leaf member being curved so that the lower surface of said roller is in contact with the upper end portion of the leaf member at a position slightly remote from the upper end thereof, and wherein the upper end portion of said leaf member is curved rearwardly and downwardly in the direction of movement of said sheet material, and wherein the leaf member contacts the roller along a line in vertical alignment with the horizontal axis of the roller.
Claim 2
Independent Claim
184 words
A device for squeezing a liquid carrying sheet material comprising a roller rotatable about a fixed horizontal axis, means for driving said roller, a resilient leaf member supported at the lower end thereof beneath said roller and having an upper end portion in pressure contact with the lower surface of the roller, sheet material being directed between the roller and the leaf member and being moved by contact with said roller, the upper end of the leaf member being directed rearwardly with respect to the advance of said sheet material passing between the roller and the leaf member, and the upper end portion of said leaf member being curved so that the lower surface of said roller is in contact with the upper end portion of the leaf member at a position slightly remote from the upper end thereof, and wherein the upper end portion of said leaf member is curved rearwardly and downwardly in the direction of movement of said sheet material, and wherein the leaf member contacts the roller along a line in vertical alignment with the horizontal axis of the roller.
Claim 3
Dependent Claim
51 words
A sheet squeezing device as defined in claim 1 wherein a guide plate is provided in front of the leaf member and below said sheet material such that the sheet material is prevented from sagging downward as it apprOaches the line of contact between said resilient leaf member and said roller.
Claim 4
Dependent Claim
15 words
A sheet squeezing device as claimed in claim 1 where the leaf member is hydrophobic.
Claim 5
Dependent Claim
19 words
A sheet squeezing device as claimed in claim 2 where the leaf member and the guide member are hydrophobic.
