Abstract
Abstract A method of making a printing ribbon spool is disclosed for maintaining the original print-out density or consistency of a printing ribbon by contact between a pad on the spool and a side edge of the ribbon. Ink is communicated to the pad from a sealed reservoir by way of a wick which communicates with the reservoir through a hole substantially smaller in diameter than the normal uncompressed diameter of the wick.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A method of replenishing ink in a printing ribbon comprising withdrawing ink from a sealed reservoir by capillary action using a wick of compressible material having one end communicating with said reservoir by way of an opening smaller in dimensions than the transverse dimensions of said wick in its uncompressed state, compressing said wick at said opening, transferring the ink from said reservoir by said wick to a deformable pad, transferring ink from the pad to a printing ribbon by contact between the pad and a side edge of the ribbon, and initiating said transfer of ink from said reservoir to said pad by flexing an exposed portion of said pad.
Claim 2
Independent Claim
111 words
A method of replenishing ink in a printing ribbon comprising withdrawing ink from a sealed reservoir by capillary action using a wick of compressible material having one end communicating with said reservoir by way of an opening smaller in dimensions than the transverse dimensions of said wick in its uncompressed state, compressing said wick at said opening, transferring the ink from said reservoir by said wick to a deformable pad, transferring ink from the pad to a printing ribbon by contact between the pad and a side edge of the ribbon, and initiating said transfer of ink from said reservoir to said pad by flexing an exposed portion of said pad.
Claim 3
Independent Claim
111 words
A method of replenishing ink in a printing ribbon comprising withdrawing ink from a sealed reservoir by capillary action using a wick of compressible material having one end communicating with said reservoir by way of an opening smaller in dimensions than the transverse dimensions of said wick in its uncompressed state, compressing said wick at said opening, transferring the ink from said reservoir by said wick to a deformable pad, transferring ink from the pad to a printing ribbon by contact between the pad and a side edge of the ribbon, and initiating said transfer of ink from said reservoir to said pad by flexing an exposed portion of said pad.
Claim 4
Independent Claim
111 words
A method of replenishing ink in a printing ribbon comprising withdrawing ink from a sealed reservoir by capillary action using a wick of compressible material having one end communicating with said reservoir by way of an opening smaller in dimensions than the transverse dimensions of said wick in its uncompressed state, compressing said wick at said opening, transferring the ink from said reservoir by said wick to a deformable pad, transferring ink from the pad to a printing ribbon by contact between the pad and a side edge of the ribbon, and initiating said transfer of ink from said reservoir to said pad by flexing an exposed portion of said pad.
Claim 5
Dependent Claim
67 words
A method in accordance with claim 1 including using first and second spools with the ribbon partially wound around each spool and having a length of approximately 1 to 2 yards, rotating the first spool in a clockwise direction while rotating the second spool in a counterclockwise direction to effect relative movement between the pad on each spool and said ribbon to effect said ink transferring step.
Claim 6
Dependent Claim
20 words
A method in accordance with claim 1 including locating the reservoir in the spool hub radially inwardly of said pad.
Claim 7
Dependent Claim
23 words
A method in accordance with claim 1 including transferring ink from said reservoir to said pad at two discrete locations on the pad.
