Abstract
Abstract A method for indexing an item from one station of apparatus to another station thereof, the method including the steps of rotating an indexible table relative to a frame in one rotational direction with the indexible table carrying the item, moving a movable bumper carried by the frame into the path of movement of an abutment carried by the indexible table so that the abutment will abut the bumper and thereby stop movement of the indexible table in that one direction when the indexible table has been rotated from one rotational position thereof to another rotational position thereof, and, thereafter, accurately positioning the indexible table with a positioning device carried by the frame and cooperating with a positioning device of the indexible table to position and hold the indexible table in its new rotational position, the positioning devices being separate from the abutment and bumper.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 words
A method for indexing an item from one station of an apparatus to another station thereof comprising the steps of rotating an indexible member relative to a frame means in one rotational direction with the indexible member carrying said item, moving movable bumper means carried by said frame means into the path of movement of an abutment means carried by the indexible member so that the abutment means will abut said bumper means and thereby stop movement of said indexible member in said one direction when said indexible member has been rotated from one rotational position thereof to another rotational position thereof, and, thereafter, accurately positioning said indexible member with positioning means carried by said frame means and cooperating with positioning means of said indexible member to position and hold said indexible member in its new rotational position, said positioning means being separate from said abutment means and said bumper means and being disposed substantially 180* therefrom when said abutment means abuts said bumper means.

Dependent Claim
20 words
A method as set forth in claim 1 wherein said indexible member is rotated approximately 180* during each indexing thereof.
Claim 4
Independent Claim
158 words
A method for indexing an item from one station of an apparatus to another station thereof comprising the steps of rotating an indexible member relative to a frame means in one rotational direction with the indexible member carrying said item, moving movable bumper means carried by said frame means into the path of movement of an abutment means carried by the indexible member so that the abutment means will abut said bumper means and thereby stop movement of said indexible member in said one direction when said indexible member has been rotated from one rotational position thEreof to another rotational position thereof, and, thereafter, accurately positioning said indexible member with positioning means carried by said frame means and cooperating with positioning means of said indexible member to position and hold said indexible member in its new rotational position, said positioning means being separate from said abutment means and said bumper means, said bumper means comprising a shock absorber.
Claim 5
Independent Claim
158 words
A method for indexing an item from one station of an apparatus to another station thereof comprising the steps of rotating an indexible member relative to a frame means in one rotational direction with the indexible member carrying said item, moving movable bumper means carried by said frame means into the path of movement of an abutment means carried by the indexible member so that the abutment means will abut said bumper means and thereby stop movement of said indexible member in said one direction when said indexible member has been rotated from one rotational position thEreof to another rotational position thereof, and, thereafter, accurately positioning said indexible member with positioning means carried by said frame means and cooperating with positioning means of said indexible member to position and hold said indexible member in its new rotational position, said positioning means being separate from said abutment means and said bumper means, said bumper means comprising a shock absorber.
Claim 6
Independent Claim
168 words
A method for indexing an item from one station of an apparatus to another station thereof comprising the steps of rotating an indexible member relative to a frame means in one rotational direction with the indexible member carrying said item, moving movable bumper means carried by said frame means into the path of movement of an abutment means carried by the indexible member so that the abutment means will abut said bumper means and thereby stop movement of said indexible member in said one direction when said indexible member has been rotated from one rotational position thereof to another rotational position thereof, and, thereafter, accurately positioning said indexible member with positioning means carried by said frame means and cooperating with positioning means of said indexible member to position and hold said indexible member in its new rotational position, said step of moving said bumper means comprising the step of operating a piston and cylinder arrangement carried by said frame means and being operatively interconnected to said bumper means.
Claim 7
Independent Claim
168 words
A method for indexing an item from one station of an apparatus to another station thereof comprising the steps of rotating an indexible member relative to a frame means in one rotational direction with the indexible member carrying said item, moving movable bumper means carried by said frame means into the path of movement of an abutment means carried by the indexible member so that the abutment means will abut said bumper means and thereby stop movement of said indexible member in said one direction when said indexible member has been rotated from one rotational position thereof to another rotational position thereof, and, thereafter, accurately positioning said indexible member with positioning means carried by said frame means and cooperating with positioning means of said indexible member to position and hold said indexible member in its new rotational position, said step of moving said bumper means comprising the step of operating a piston and cylinder arrangement carried by said frame means and being operatively interconnected to said bumper means.
