Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
189 words
Apparatus for transferring objects between stations comprising: a plurality of equally spaced radially extending arms, an indexing table interconnecting said arms within a common plane and having at least one aperture formed therein, a rotating table, means for rotating said rotating table, column means attached to said rotating table and extending through said aperture in said indexing table for interconnecting said rotating table and said indexing table to impart simultaneous unidirectional rotational motion thereto and to permit relative movement between said tables in a direction normal to the axis of rotation thereof, means for elevating said indexing table extending through said rotating means, rotation preventing means coacting with said index table and arranged so as to permt rotation of said indexing table only in the elevated position, means for engaging the objects connected to said arms for supporting the objects during transfer between stations, and means positioned in the path of movement of said means for engaging the objects to control the means for engaging the objects so that they are engaged at all times when said elevating means is raised and released when said elevating means is lowered.
Claim 2
Dependent Claim
189 words
Apparatus for transferring objects between stations comprising: a plurality of equally spaced radially extending arms, an indexing table interconnecting said arms within a common plane and having at least one aperture formed therein, a rotating table, means for rotating said rotating table, column means attached to said rotating table and extending through said aperture in said indexing table for interconnecting said rotating table and said indexing table to impart simultaneous unidirectional rotational motion thereto and to permit relative movement between said tables in a direction normal to the axis of rotation thereof, means for elevating said indexing table extending through said rotating means, rotation preventing means coacting with said index table and arranged so as to permt rotation of said indexing table only in the elevated position, means for engaging the objects connected to said arms for supporting the objects during transfer between stations, and means positioned in the path of movement of said means for engaging the objects to control the means for engaging the objects so that they are engaged at all times when said elevating means is raised and released when said elevating means is lowered.
Claim 3
Dependent Claim
19 words
Apparatus in accordance with claim 1 wherein said means for elevating said indexing means includes a pressure fluid cylinder.
Claim 4
Dependent Claim
38 words
Apparatus in accordance with claim 1 wherein said means for engaging the objects includes securing members for engaging the object, means for energizing said securing members and interconnecting linkage between said securing members and said means for energizing.
Claim 5
Dependent Claim
50 words
Apparatus in accordance with claim 1 wherein said means for engaging the objects includes securing members, means for biassing said securing members to cause said members to converge toward each other, and means for selectively engaging said securing members to part said members against the force of said biassing means.
Claim 6
Dependent Claim
86 words
Apparatus in accordance with claim 4 wherein each of said securing members includes a half of a collar, opposing pivot members on each of said collar halves, ears and points on said pivot members and wherein said means for biassing is attached to said collar halves to urge said halves toward each other, said ears contacting the object upon said collar being placed over a portion thereof causing said pivot members to pivot and thereby converge said points toward each other to embed in the object.
Claim 7
Dependent Claim
87 words
Apparatus in accordance with claim 1 wherein said means for engaging the objects includes sliding elements slidable with respect to said arm for engaging the interior of the objects and in opposing relationship to each other, means biassing said elements towards each other, means for moving said elements outwardly from each other toward the object in opposition to said biassing means, said means for moving being engageable by the object, and means for releasing said means for moving said elements to disengage said elements from the object.
Claim 8
Dependent Claim
15 words
Apparatus in accordance with claim 6 wherein said means biassing said elements includes a spring.
Claim 9
Dependent Claim
55 words
Apparatus in accordance with claim 6 wherein said means for moving said elements outwardly from each other includes a wedge slidable between said elements, a housing engageable with the object, and a spring interconnecting said housing with said wedge forcing said wedge between said elements when the object engages said housing to energize said spring.
Claim 10
Dependent Claim
29 words
Apparatus in accordance with claim 6 wherein said means for releasing said means for moving said elements includes a release pin affixed to said means for moving said elements.
Claim 11
Dependent Claim
24 words
Apparatus in accordance with claim 1 including means for radially extending said means for engaging the objects intermediate said arms and said engaging meAns.
Claim 12
Dependent Claim
46 words
Apparatus in accordance with claim 10 wherein said means for radially extending said means for engaging the objects includes a slide bar mounted on said arm and capable of longitudinal movement relative to said arm, and means for moving said slide bar relative to said arm.
