Abstract
Abstract An article transfer device including a rotatable wheel having at least one recessed pocket therein, an ejecting member disposed within the pocket and biasing means normally urging the ejecting member upwardly out of the pocket. A plate extends partially over the wheel and articles are gravitationally fed individually through an opening in the plate and into the pocket. As the wheel rotates, the article introduced into the pocket is sandwiched between the ejecting member and the underside of the plate and the biasing means are compressed. As the pocket rotates beneath a cutaway portion of the plate, the ejecting member ejects the article out of the pocket, under influence of the biasing means, and the article is directed onto a guide ramp.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
An article transfer device comprising: a rotatable means having at least one article receiving pocket therein; a member mounted within said pocket for supporting an article which is introduced into said pocket; means for introducing an article into said pocket for support by said member; a plate at least partially overlying said rotatable means; biasing means normally urging said member toward said plate; and said device thus being operative to receive an article upon said member and to sandwich said article between said plate and said member as said rotatable means rotates, said article being ejected from said pocket by said member and said biasing means when said pocket rotates to a position where said plate no longer overlies said article.
Claim 2
Dependent Claim
121 words
An article transfer device comprising: a rotatable means having at least one article receiving pocket therein; a member mounted within said pocket for supporting an article which is introduced into said pocket; means for introducing an article into said pocket for support by said member; a plate at least partially overlying said rotatable means; biasing means normally urging said member toward said plate; and said device thus being operative to receive an article upon said member and to sandwich said article between said plate and said member as said rotatable means rotates, said article being ejected from said pocket by said member and said biasing means when said pocket rotates to a position where said plate no longer overlies said article.
Claim 3
Dependent Claim
35 words
An article transfer device as defined in claim 1 wherein said rotatable means is a wheel having an upper and a lower surface and wherein said pocket is formed at the periphery of said wheel.
Claim 4
Dependent Claim
39 words
An article transfer device as defined in claim 2 wherein said pocket is recessed from said upper surface axially of the axis of rotation of said wheel, thus leaving a web portion of said wheel extending beneath said pocket.
Claim 5
Dependent Claim
28 words
An article transfer device as defined in claim 3 wherein said biasing means is interposed between and reacts against said web portion and the underside of said member.
Claim 6
Dependent Claim
67 words
An article transfer device as defined in claim 4 wherein said biasing means includes a plurality of pins having one end attached to the underside of said member and having the other end projecting through said web portion and terminatinG in an enlarged head which abuts against said wheel lower surface at the underside of said web portion, and a compression spring surrounding each of said pins.
Claim 7
Dependent Claim
25 words
An article transfer device as defined in claim 1 wherein said plate has a cutaway portion which exposes said pocket as said rotatable means rotates.
Claim 8
Dependent Claim
37 words
An article transfer device as defined in claim 1 wherein said means for introducing an article into said pocket includes an upstanding chute means mounted on said plate and adapted to contain a plurality of stacked articles.
Claim 9
Dependent Claim
54 words
An article transfer device as defined in claim 7 wherein said plate has an opening therein beneath said chute means, said opening being aligned with said pocket at one position of rotation of said rotatable means so that an article from said chute means can gravitationally drop through said opening and into said pocket.
Claim 10
Dependent Claim
28 words
An article transfer device as defined in claim 1 further including a guide ramp adjacent said rotatable means for receiving and directing an article ejected from said pocket.
Claim 11
Dependent Claim
