Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 217 words
A device for automatically feeding individual original forms to receiving means in a copying machine comprising a housing mounted alongside said receiving means and arranged for vertical movement in increments; a plurality of table means fixed to said housing and including a plurality of tables respectively positioned thereon in sliding contact, said table means being vertically spaced within said housing and said tables arranged to have an individual original form placed on each; delivery means including a reciprocatory lever positioned on the side of said housing opposite to the side where the receiving means is positioned, said delivery means located at the same horizontal level as said receiving means; a plurality of springs corresponding in number to said table means and individually attached thereto; each said spring having one end attached to a bottom surface of an individual table, and the other end of said spring is fixed to said housing to provide a bias for said table toward said delivery means; and sensing means for automatically initiating incremental vertical movement of said housing to successively align each table means with said lever which reciprocates to slide an individual table toward said receiving means to deliver an individual form thereto, and said spring acting to retract said table toward said delivery means after delivery of said form.
Claim 2
Independent Claim 217 words
A device for automatically feeding individual original forms to receiving means in a copying machine comprising a housing mounted alongside said receiving means and arranged for vertical movement in increments; a plurality of table means fixed to said housing and including a plurality of tables respectively positioned thereon in sliding contact, said table means being vertically spaced within said housing and said tables arranged to have an individual original form placed on each; delivery means including a reciprocatory lever positioned on the side of said housing opposite to the side where the receiving means is positioned, said delivery means located at the same horizontal level as said receiving means; a plurality of springs corresponding in number to said table means and individually attached thereto; each said spring having one end attached to a bottom surface of an individual table, and the other end of said spring is fixed to said housing to provide a bias for said table toward said delivery means; and sensing means for automatically initiating incremental vertical movement of said housing to successively align each table means with said lever which reciprocates to slide an individual table toward said receiving means to deliver an individual form thereto, and said spring acting to retract said table toward said delivery means after delivery of said form.
Claim 3
Dependent Claim 127 words
A device according to claim 1 in which each said table means includes a first platform element supporting part of an individual table and fixed to said housing on the side adjacent to said delivery means, sAid one end of said spring attached to said fixed first element, and each said table means includes a second platform element supporting another part of an individual table and fixed to said housing on the side adjacent to said receiving means, said second platform element including a slot for said one end of said spring to pass therethrough upon reciprocating movement of said lever sliding said table toward said receiving means, said platform elements being longitudinally spaced with respect to each other to receive the individual table in sliding contact.
