Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
Recording device, particularly for measuring and registering devices and the like for supplying ink on a registering surface for effecting a record, comprising an ink reservoir, a capillary tube having a first end and a second end with the first end located within said ink reservoir for suctioning ink therefrom by its capillary action and the second end spaced outwardly from said ink reservoir, said capillary tube is formed for the entire length from the first end to the second end of a flexible, wear-resistant plastics material, said plastics material is polyacetal, said second end of said capillary tube comprising a recording tip for supplying ink suctioned by said capillary tube directly from said capillary tube to the registering surface on writing contact of said recording tip with the registering surface, a carriage movable relative to said ink reservoir, said second end of said capillary tube is secured to said carriage for movement therewith so that said second end can traverse the registering surface, and said capillary tube has a uniform interior structure for the length thereof from said first end to said second end.
Claim 2
Dependent Claim
