Abstract
Abstract An inexpensive and efficient device which guarantees a satisfactory draining of waste ink accumulating on a rejection shutter in a spray printing device comprises a discharge channel member positioned below the rejection shutter and inclined from the horizontal by approximately 3*. The discharge channel member is formed of an elongated strip of sheet material bent at several points parallel to its length and joined to the rejection shutter to form a groove along their intersecting portions which groove will exert a capillary influence on the waste ink and thereby cause it to drain to a waste ink receptacle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
Waste ink disposal apparatus for excess ink in a spray printing device comprising: rejection shutter means below a recording area, adapted to receive a spray of ink; upwardly opening discharge channel means positioned below the upper edge of said rejection shutter means whereby ink hitting said shutter means will drain into said channel means; said channel means providing a capillary groove extending therealong inclined slightly downwardly and along which the waste ink flows toward waste ink receiving means at its lower end receptive of the ink which drains into the channel means; said groove providing for capillary action between it and the waste ink to accelerate conveying the waste ink to the receiving means whereby to avoid thickening and drying of the ink in the channel means; and a vertical capillary channel adjacent to said lower end of said groove, said vertical channel providing for capillary influence on said waste ink to accelerate conveying said waste ink to said waste ink receiving means.

Claim 5
Dependent Claim
40 words
Apparatus according to claim 1, including a vertical capillary channel adjacent to said lower end of said groove, said vertical channel providing for capillary influence on said waste ink to accelerate conveying said waste ink to said waste ink receptacle.
Claim 6
Independent Claim
135 words
A method of waste ink disposal for excess ink in a spray device in which the excess ink is received by rejection shutter means below a recording area and wherein the ink is liable to thicken and dry by evaporation, comprising: receiving the excess ink from said rejection shutter means in upwardly opening discharge channel means positioned below the upper edge of the rejection shutter means; effecting accelerated capillary conveyance of the ink by capillary action along a capillary groove in said channel means inclined downwardly toward a discharge end; and receiving the waste ink from the lower end of said channel means capillary groove in a vertical capillary groove extending therebelow and thereby gravitationally and by capillary action accelerating movement of the waste ink to waste ink receiving means below said vertical capillary groove.
