## Abstract

A cleaning wiper adapted to automatically maintain a fresh cleaning surface upon each utilization. Supply and take-up holders are mounted in a body for holding rolls of a cleaning web. The cleaning web, intermediate the supply and take-up holders, passes over a support member movably mounted within and accessible through a slot in one side of the body. Utilization of the cleaning wiper causes the support member to be moved from its resiliently biased position within the slot and activates an advance linkage. The advance linkage advances the rotation of the take-up holder a predetermined amount.

## Claims

### Claim 1

A cleaning wiper adapted to hold a roll of cleaning web, comprising:
a body having a slot along one side thereof;
a support member movably mounted within said body, a portion of which is accessible through said slot;
a supply holder mounted in said body adapted to hold said roll of said cleaning web;
a take-up holder mounted in said body adapted to hold a take-up roll for said cleaning web;
said cleaning web when intermediate said supply roll and said take-up roll passing over said portion of said support member forming a cleaning surface;
said support member being resiliently biased within said slot; and
an advance linkage activated by movement of said support member within said slot and coupled to said take-up holder for advancing the rotation of said take-up holder a predetermined amount;
whereby said cleaning surface maintains a fresh portion of said cleaning web by automatically advancing said cleaning web as said cleaning wiper is utilized.

### Claim 2 (depends on 1)

A cleaning wiper as in claim 1 which further comprises a one-way clutch operatively coupled to said take-up holder.

### Claim 3 (depends on 1)

A cleaning wiper as in claim 1 wherein said portion of said support member extends through said slot.

### Claim 4 (depends on 3)

A cleaning wiper as in claim 3 wherein said support member is pivotably mounted within said body.

### Claim 5 (depends on 4)

A cleaning wiper as in claim 4 wherein said support member is biased toward one side of said slot and wherein said advance linkage is activated by a movement of said support member away from said one side of said slot.

### Claim 6 (depends on 5)

A cleaning wiper as in claim 5 wherein said support member is pivotably mounted on the axis of said supply holder.

### Claim 7 (depends on 6)

A cleaning wiper as in claim 6 wherein said advance linkage comprises:
a first lever mounted on the axis of said supply holder and fixed with respect to said wiper blade;
a second lever mounted on the axis of said take-up holder engaging said first lever;
a first one-way clutch mounted on the axis of said take-up holder operatively coupling said second lever with said take-up holder; and
a second one-way clutch mounted on the axis of said take-up holder operatively coupling said take-up holder to said body.

### Claim 8 (depends on 8)

A cleaning wiper as in claim 8 wherein said support member has compressible foam contacting said cleaning web.
