Abstract
Abstract A cup holder sleeve and its support assembly for use in a drawing and ironing machine that has a circular bore and is supported for radial as well as tilting movement of the axis of the elongated bore with respect to the support. The support includes a pair of members that cooperate to define a recess surrounding a circular opening and an enlarged portion of the cup holder sleeve is received into the recess and cooperates with a cupper support element. The cup holder support element and cup holder sleeve are normally radially centered with respect to the opening by centering springs and the cup holder sleeve is normally maintained in engagement with the support element by hold-down springs. The cup holder sleeve and support element can be moved radially while the cup holder sleeve can be tilted with respect to the support element and all of the elements are normally maintained in a predetermined position by the centering springs and the hold-down springs.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
177 words
In a drawing and ironing machine including a fixed frame, a ring carried by said fixed frame and having a first circular opening therein, a punch movable axially of said first circular opening, a cup holder sleeve interposed between said punch and said ring, said cup holder sleeve having an axial bore for receiving said punch, and a support for said cup holder sleeve, the improvement of said support including a first member having a second circular opening therein aligned with said first circular opening and having a circumferential recess extending from the periphery thereof, a movable support element having a peripheral portion received in said recess and cooperating with one end of said cup holder sleeve, said support element having a circular aperture and being movable radially of said second circular opening, and biasing means between said first member and said support element normally maintaining said support element centered with respect to said second circular opening and accommodating radial movement of said one end of said cup holder sleeve and said support element in said openings.
Claim 2
Dependent Claim
177 words
In a drawing and ironing machine including a fixed frame, a ring carried by said fixed frame and having a first circular opening therein, a punch movable axially of said first circular opening, a cup holder sleeve interposed between said punch and said ring, said cup holder sleeve having an axial bore for receiving said punch, and a support for said cup holder sleeve, the improvement of said support including a first member having a second circular opening therein aligned with said first circular opening and having a circumferential recess extending from the periphery thereof, a movable support element having a peripheral portion received in said recess and cooperating with one end of said cup holder sleeve, said support element having a circular aperture and being movable radially of said second circular opening, and biasing means between said first member and said support element normally maintaining said support element centered with respect to said second circular opening and accommodating radial movement of said one end of said cup holder sleeve and said support element in said openings.
Claim 3
Dependent Claim
43 words
A drawing and ironing machine as defined in claim 1, further including means between said support element and said cup holder sleeve accommodating tilting of the axis of said axial bore with respect to an axis through the centers of said circular openings.
Claim 4
Dependent Claim
56 words
A drawing and ironing machine as defined in claim 2, in which said last means includes confronting arcuate surfaces between said support element and said cup holder sleeve and further biasing means for urging said surfaces into engagement with each other, said further biasing means yielding to allow said surfaces to move relative to each other.
Claim 5
Dependent Claim
21 words
A drawing and ironing machine as defined in claim 3, further including lubricating means for applying lubricant between said confronting surfaces.
Claim 6
Dependent Claim
29 words
A drawing and ironing machine as defined in claim 4, in which one of said surfaces has a continuous recess therein and the lubricant is delivered to said recess.
Claim 7
Dependent Claim
47 words
A drawing and ironing machine as defined in claim 1, in which said recess in said first member defines a shoulder with said support element having a contact surface in engagement with said shoulder further including means for applying lubricant between said shoulder and said contact surface.
Claim 8
Dependent Claim
24 words
A drawing and ironing machine as defined in claim 6, further including hold-down springs for biasing said contact surface into engagement with said shoulder.
Claim 9
Dependent Claim
59 words
A drawing and ironing machine as defined in claim 7, in which said support element and cup holder sleeve have mating spherical surface segments accommodating tilting of said cup holder sleeve with respect to the axis of said circular aperture and said hold-down springs normally maintain said bore in said cup holder sleeve axially aligned with said circular aperture.
Claim 10
Dependent Claim
137 words
A cup holder sleeve assembly for use with a punch of an ironing machine comprising a support having an opening therein with a recess extending from the periphery of said opening, an elongated cup holder sleeve having an axial bore therein and an enlarged portion at one end received in said recess, a support element having an aperture therein and having a peripheral portion received in said recess with said recess having a shoulder surface extending perpendicular to the axis of said aperture and said peripheral portion having a contiguous cooperating surface, means for applying lubricant to said surfaces to accommodate radial movement of said aperture with respect to said opening, first biasing means normally maintaining said aperture centered with respect to said opening and second biasing means normally maintaining said surfaces in engagement with each other.
Claim 11
Dependent Claim
137 words
A cup holder sleeve assembly for use with a punch of an ironing machine comprising a support having an opening therein with a recess extending from the periphery of said opening, an elongated cup holder sleeve having an axial bore therein and an enlarged portion at one end received in said recess, a support element having an aperture therein and having a peripheral portion received in said recess with said recess having a shoulder surface extending perpendicular to the axis of said aperture and said peripheral portion having a contiguous cooperating surface, means for applying lubricant to said surfaces to accommodate radial movement of said aperture with respect to said opening, first biasing means normally maintaining said aperture centered with respect to said opening and second biasing means normally maintaining said surfaces in engagement with each other.
Claim 12
Dependent Claim
