Abstract
Abstract A device for cleaning ink pen points of the type which are removable from an ink pen. The device includes an upper section and a lower section complementally engagable with each other, so as to support the pen point in a vertical attitude for sequential attack by cleaning water and drying air. The device includes a jet pump portion actuated by the cleaning water, so as to advance drying air through the pen point. The device is characterized by its mechanical simplicity, yet extreme effectiveness in cleaning artists and stylographic drafting pen points.

Claim 1
Independent Claim
207 words
A device for cleaning ink pen points comprising: A. a housing having a lower section and an upper section; i. said lower section defining: a. a chamber for support and cleaning of an ink pen point and, b. a jet pump communicable with said chamber, as well as a source of cleaning water and including a drain conduit; ii. said upper section defining; a. a lug like extension having an axial bore communicating with said chamber and complementally engagable at its exterior with the wall of said chamber; b. an air inlet conduit communicating with said chamber in said lower section; c. a water inlet conduit communicating with said jet pump in said lower section; and d. a valve having water and air conduits therethrough, said valve being rotatably supported intermediate said air inlet conduit and said water inlet conduit in said upper section, so as to be rotatable from a water cleaning position in which said water conduit is aligned with said water inlet conduit and with said chamber, to an air drying position in which said air drying conduit is aligned with said air inlet conduit and with said chamber and said water conduit is aligned said water inlet conduit and with said jet pump.
Claim 2
Independent Claim
207 words
A device for cleaning ink pen points comprising: A. a housing having a lower section and an upper section; i. said lower section defining: a. a chamber for support and cleaning of an ink pen point and, b. a jet pump communicable with said chamber, as well as a source of cleaning water and including a drain conduit; ii. said upper section defining; a. a lug like extension having an axial bore communicating with said chamber and complementally engagable at its exterior with the wall of said chamber; b. an air inlet conduit communicating with said chamber in said lower section; c. a water inlet conduit communicating with said jet pump in said lower section; and d. a valve having water and air conduits therethrough, said valve being rotatably supported intermediate said air inlet conduit and said water inlet conduit in said upper section, so as to be rotatable from a water cleaning position in which said water conduit is aligned with said water inlet conduit and with said chamber, to an air drying position in which said air drying conduit is aligned with said air inlet conduit and with said chamber and said water conduit is aligned said water inlet conduit and with said jet pump.
