Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
An applicator for applying a small quantity of a biological liquid to sharp prongs on an intermittently fed continuous strip of scarifying plates having sharp prongs projecting downwardly therefrom comprising, in combination: A. a tank to contain a biological liquid B. means supporting said strip in continuous straight configuration over said tank; C. dipping means to place said liquid in contact with said prongs; comprising a dipper having at least one cuplike receptacle, said receptacle having an outer peripheral wall, and a meniscus flattening inner peripheral wall, with a drainage opening therein, and disposed in said tank with said receptacle adjacent and below the path of movement of said prongs, and an arm connecting said dipper to an assembly mounted to slide up and down to reciprocate said receptacle toward and away from said prongs, and D. drive means actuating said dipping means in coordination with the feed rate of said strip, so that each said prong is dipped into said liquid.
Claim 2
Dependent Claim
162 words
An applicator for applying a small quantity of a biological liquid to sharp prongs on an intermittently fed continuous strip of scarifying plates having sharp prongs projecting downwardly therefrom comprising, in combination: A. a tank to contain a biological liquid B. means supporting said strip in continuous straight configuration over said tank; C. dipping means to place said liquid in contact with said prongs; comprising a dipper having at least one cuplike receptacle, said receptacle having an outer peripheral wall, and a meniscus flattening inner peripheral wall, with a drainage opening therein, and disposed in said tank with said receptacle adjacent and below the path of movement of said prongs, and an arm connecting said dipper to an assembly mounted to slide up and down to reciprocate said receptacle toward and away from said prongs, and D. drive means actuating said dipping means in coordination with the feed rate of said strip, so that each said prong is dipped into said liquid.
Claim 3
Dependent Claim
34 words
An apparatus as defined in claim 1 wherein said drive means comprises a cam follower on said assembly and a driven eccentrically mounted cam in contact with said cam follower for reciprocating said assembly.
Claim 4
Dependent Claim
36 words
An apparatus as defined in claim 1 including a weight pivotally mounted over said tank and positioned to rest on said strip to maintain said strip in alignment for even coating of liquid on said prongs.
Claim 5
Dependent Claim
59 words
An apparatus as defined in claim 2 including a pusher arm having one end eccentrically mounted to said cam, the other end being free and adapted to engage said strip when actuated by said cam in a direction away from said tank whereby said arm pulls said strip through said applicator in synchronization with the reciprocation of said dipper.
