Abstract
Abstract Ink is applied through a substantially closed system onto the surface of an engraved wheel which prints a legend or design onto a wire running tangentially against the wheel. A peristaltic pump delivers ink from a closed ink reservoir through a conduit formed with a discharge opening dimensioned to accommodate the periphery of the printing wheel which rotates in the conduit opening to receive a coating of ink. A fork-shaped plastic wiper removes excess ink from the wheel prior to engaging the wire. An applicator housing is formed with a drain to collect excess ink and return it via a conduit to the ink reservoir. The housing is spring-loaded to bear against the wheel and is mounted for movement as a unit to and away from the wheel to permit cleaning and/or changing of the wheel. The peristaltic pump is formed with a movable wall portion to relieve pressure from the conduit when the system is shut down in order to allow complete draining of the lines.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
Apparatus for printing on a running strand such as wire or the like, comprising a. a support, b. a rotatable printing wheel mounted to said support and formed with peripheral printing indicia, c. means for guiding said strand against the printing portion of said wheel, d. a substantially closed applicator cooperatively positioned adjacent said wheel and formed with an opening adapted to receive a portion of said wheel, e. a peristaltic pump connected to a supply of printing liquid and to said applicator for delivering a flow of said liquid through said applicator against said wheel, and, f. a drain conduit connected to said applicator and said supply for returning excess liquid to said supply, g. said applicator including a tubular conduit connected to said pump and extending into said applicator in tangential relation to said wheel, said conduit being formed with a restricted slot opening to receive a chordal portion of said wheel for direct application of liquid thereon, h. said applicator including a wiper in wiping contact with the printing portion of said wheel to remove excess liquid therefrom.
Claim 2
Dependent Claim
181 words
Apparatus for printing on a running strand such as wire or the like, comprising a. a support, b. a rotatable printing wheel mounted to said support and formed with peripheral printing indicia, c. means for guiding said strand against the printing portion of said wheel, d. a substantially closed applicator cooperatively positioned adjacent said wheel and formed with an opening adapted to receive a portion of said wheel, e. a peristaltic pump connected to a supply of printing liquid and to said applicator for delivering a flow of said liquid through said applicator against said wheel, and, f. a drain conduit connected to said applicator and said supply for returning excess liquid to said supply, g. said applicator including a tubular conduit connected to said pump and extending into said applicator in tangential relation to said wheel, said conduit being formed with a restricted slot opening to receive a chordal portion of said wheel for direct application of liquid thereon, h. said applicator including a wiper in wiping contact with the printing portion of said wheel to remove excess liquid therefrom.
Claim 3
Dependent Claim
32 words
Apparatus according to claim 1 wherein said wiper is a plastic rod and formed with a wheel engaging diagonal slot diametrically across one end thereof for wiping excess liquid from said wheel.
Claim 4
Dependent Claim
34 words
Apparatus according to claim 1 including means mounting said applicator to said support for movement to and away from said wheel and locking means for locking said applicator in operative position against said wheel.
Claim 5
Dependent Claim
25 words
Apparatus according to claim 3 wherein said mounting means includes a pair of spaced parallel links pivoted to said support and pivotally carrying said applicator.
Claim 6
Dependent Claim
30 words
Apparatus according to claim 4 wherein said locking means is a member adapted to engage one of said links to said support to prevent pivoting of both of said links.
Claim 7
Dependent Claim
18 words
Apparatus according to claim 1 including control means connected to said pump for selectively varying the speed thereof.
Claim 8
Dependent Claim
100 words
Apparatus according to claim 1 wherein said pump includes at least one roller, drive means connected to said roller for rotating said roller about an offset axis, a stationary wall formed with an arcuate surface disposed in closely spaced relation to said roller and a length of flexible, resilient tubing disposed between said roller and said surface and connected to said supply of liquid whereby liquid will be pumped through said tubing upon rotation of said roller, said wall and said roller being relatively movable with respect to one another for selectively varying the spacing between said wall and roller.
Claim 9
Dependent Claim
34 words
Apparatus according to claim 1 wherein one portion of said applicator is hinged to another portion thereof and a resilient member is disposed between said portions for urging said one portion towards said wheel.
