Mileger - Web page: https://patentgrep.com/patent/US10479120B1 ## CPC - B41J 29/377: Cooling or ventilating arrangements - B41J: TYPEWRITERS; SELECTIVE PRINTING MECHANISMS, i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME; CORRECTION OF TYPOGRAPHICAL ERRORS ## Abstract An apparatus for cooling a print head implemented on a wire and cable manufacturing line, the apparatus comprising a sleeve, wherein the sleeve has an internal portion and an external portion and wherein the sleeve forms an internal void marginally larger than the size of the print head and wherein the sleeve further comprises an elongated surface; a front surface connected to the elongated surface, wherein the front surface comprises an ink outlet opening; a rear surface connected to the elongated surface, wherein the rear surface comprises a cable opening; a channel connected to the internal portion of the sleeve, wherein the channel comprises an open side facing the internal void and wherein the channel on the internal portion of the sleeve extends from the rear to the front of the sleeve; an air inlet compartment in communication with the channel and enclosed by the rear surface; an air inlet in communication with the air inlet compartment; and an exhaust channel connected to the sleeve and extending from the front surface to the rear surface along the elongated surface and connected to the channel at the front of the sleeve. ## Claims ### Claim 1 An apparatus for cooling a print head implemented on a wire and cable manufacturing line, the apparatus comprising: a sleeve, wherein the sleeve has an internal portion and an external portion and wherein the sleeve forms an internal void marginally larger than the size of the print head and wherein the sleeve further comprises: a channel connected to the internal portion of the sleeve, wherein the channel comprises an open side facing the internal void and wherein the channel on the internal portion of the sleeve extends from the rear to the front of the sleeve; an air inlet compartment in communication with the channel; an air inlet in communication with the air inlet compartment; and an exhaust channel connected to the sleeve and extending from the front to the rear and connected to the channel at the front of the sleeve. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the channel is a series of channels. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the channel is a U-shaped channel. ### Claim 4 (depends on 1) The apparatus of claim 1 further comprising a mounting apparatus attached to the external portion of the sleeve. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the air inlet is capable of being connected to a compressed air supply. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the channel is wrapped helically along the internal portion of the sleeve. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the exhaust channel is connected to the internal portion of the sleeve. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the exhaust channel is connected to the external portion of the sleeve. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the sleeve is a rectangular sleeve. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the sleeve is a cylindrical sleeve. ### Claim 11 A system for cooling a print head, the system comprising: a manufacturing line, wherein wire and cable are manufactured on the manufacturing line; an ink printing system connected to the manufacturing line, wherein the ink printing system prints information on the wire or cable, the ink printing system further comprising: a compressed air supply; a main enclosure, wherein the main enclosure comprises an ink supply, pumping equipment, and electronics for controlling the ink printing system; an electronic cable connected to the main enclosure, the electronic cable communicating with the electronics; an air hose connected to the compressed air supply, the air house for transferring compressed air from the compressed air supply; an ink hose connected to the main enclosure, the ink house for transferring the ink supply from the main enclosure; a print head connected to the electronic cable and ink house, the print head for printing ink on the wire and cable; a sleeve, wherein the sleeve has an internal portion and an external portion and wherein the sleeve forms an internal void marginally larger than the size of the print head; wherein the print head is located within the internal void of the sleeve; and wherein the sleeve further comprises: a channel connected to the internal portion of the sleeve, wherein the channel comprises an open side facing the internal void and wherein the channel on the internal portion of the sleeve extends from the rear to the front of the sleeve; an air inlet compartment in communication with the channel; an air inlet in communication with the air inlet compartment and the air hose; and an exhaust channel connected to the sleeve and extending from the front surface to the rear surface and connected to the channel at the front of the sleeve. ### Claim 12 (depends on 11) The system of claim 11, wherein compressed air is transferred from the main enclosure to through the air hose to the channel. ### Claim 13 (depends on 12) The system of claim 12, wherein the compressed air passes through the channel and contacts the print head. ### Claim 14 (depends on 13) The system of claim 13, wherein the compressed air passing through the channel cools the print head. ### Claim 15 (depends on 13) The system of claim 13, wherein the compressed air exits through the exhaust channel after passing through the channel. ### Claim 16 (depends on 11) The system of claim 11, wherein the channel is a series of channels. ### Claim 17 (depends on 11) The system of claim 11, wherein the channel is a U-shaped channel. ### Claim 18 (depends on 11) The system of claim 11 further comprising a mounting apparatus attached to the external portion of the rectangular sleeve. ### Claim 19 (depends on 11) The system of claim 11, wherein the ink outlet opening does not impede the distribution of ink from the print head. ### Claim 20 (depends on 11) The system of claim 11, wherein the channel is wrapped helically along the internal portion of the rectangular sleeve. ### Claim 21 (depends on 11) The system of claim 11, wherein the sleeve is a rectangular sleeve. ### Claim 22 (depends on 11) The system of claim 11, wherein the sleeve is a cylindrical sleeve. ### Claim 23 (depends on 11) The system of claim 11, wherein the compressed air supply is located within the main enclosure.
