Abstract
Abstract Portions of a pin-on button are cut and assembled as a result of a plurality of operations in a machine having a vertical press. Cutter and work deforming tools are displaced by a single press ram to cut blanks and deform the blanks onto a button top placed in one of two die assemblies positioned in alignment below the work deforming tool on the lower end of the ram.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
98 words
Apparatus for making buttons or the like comprising a frame, a base fixedly mounted on the frame, a ram slidably mounted by the frame for vertical movement along an axis intersecting the base, actuating means operatively connected to the ram for imparting movement thereto downwardly and upwardly from an inactive position, fixed work holding means mounted by the frame above the ram, movable work holding means mounted on the base below the ram, and work engaging tool means displaceable within the fixed and movable work holding means by the ram in response to said upward and downward movemeNt.
Claim 2
Dependent Claim
98 words
Apparatus for making buttons or the like comprising a frame, a base fixedly mounted on the frame, a ram slidably mounted by the frame for vertical movement along an axis intersecting the base, actuating means operatively connected to the ram for imparting movement thereto downwardly and upwardly from an inactive position, fixed work holding means mounted by the frame above the ram, movable work holding means mounted on the base below the ram, and work engaging tool means displaceable within the fixed and movable work holding means by the ram in response to said upward and downward movemeNt.
Claim 3
Dependent Claim
32 words
The combination of claim 1 wherein said tool means includes a cutter engageable by the ram during upward movement and work deforming means connected to the ram at a lower end thereof.
Claim 4
Dependent Claim
60 words
The combination of claim 2 wherein said fixed work holding means includes a tubular guide fixed to the frame in concentric relation to said axis through which the ram is slidably received, and a pair of fixedly spaced plates mounted on the tubular guide having an opening within which the tool means is seated in axial alignment with said axis.
Claim 5
Dependent Claim
60 words
The combination of claim 1 wherein said fixed work holding means includes a tubular guide fixed to the frame in concentric relation to said axis through which the ram is slidably received, and a pair of fixedly spaced plates mounted on the tubular guide having an opening within which the tool means is seated in axial alignment with said axis.
Claim 6
Dependent Claim
92 words
Apparatus for making buttons or the like comprising a frame, a base fixedly mounted on the frame, a ram slidably mounted by the frame for vertical movement along an axis intersecting the base, actuating means operatively connected to the ram for imparting movement thereto downwardly and upwardly from an inactive position through a predetermined stroke, fixed work holding means mounted by the frame above the ram, and cutter means movably mounted within the work holding means for upward displacement by the ram through a cutting stroke substantially shorter than said predetermined stroke.
Claim 7
Dependent Claim
92 words
Apparatus for making buttons or the like comprising a frame, a base fixedly mounted on the frame, a ram slidably mounted by the frame for vertical movement along an axis intersecting the base, actuating means operatively connected to the ram for imparting movement thereto downwardly and upwardly from an inactive position through a predetermined stroke, fixed work holding means mounted by the frame above the ram, and cutter means movably mounted within the work holding means for upward displacement by the ram through a cutting stroke substantially shorter than said predetermined stroke.
Claim 8
Dependent Claim
60 words
The combination of claim 5 wherein said fixed work holding means includes a tubular guide fixed to the frame in concentric relation to said axis through which the ram is slidably received, and a pair of fixedly spaced plates mounted on the tubular guide having an opening within which the cutter means is seated in axial alignment with said axis.
Claim 9
Dependent Claim
94 words
In a button making machine, a frame having a base portion, an actuating mechanism mounted by the frame vertically spaced above the base portion, a work holder fixedly mounted by the frame and projecting upwardly thereabove, ram means drivingly engaged by the actuating mechanism for vertical displacement within the work holder, the work holder having a top opening through which sheet material is exposed, and cutter means movably mounted within the work holder for upward displacement by the ram means through said top opening to cut and eject a blank from the sheet material.
Claim 10
Dependent Claim
94 words
In a button making machine, a frame having a base portion, an actuating mechanism mounted by the frame vertically spaced above the base portion, a work holder fixedly mounted by the frame and projecting upwardly thereabove, ram means drivingly engaged by the actuating mechanism for vertical displacement within the work holder, the work holder having a top opening through which sheet material is exposed, and cutter means movably mounted within the work holder for upward displacement by the ram means through said top opening to cut and eject a blank from the sheet material.
Claim 11
Dependent Claim
52 words
The combination of claim 7 including work holding means movably mounted on the base portion of the frame below the ram means and work engaging tool means mounted on the ram means for displacement into said work holding means to deform the blank cut from the sheet material by the cutter means.
Claim 12
Dependent Claim
52 words
The combination of claim 8 wherein said work holder comprises a guide member into which the ram means is retracted, and a die assembly fixed to the frame within which the top opening is formed, said die assembly having a slot through which the sheet material is inserted intersecting the top opening.
Claim 13
Dependent Claim
39 words
The combination of claim 9 wherein said guide member encloses the ram means within a bore diametrically smaller than the top opening to form a seating shoulder supporting the cutter means in a retracted position within the die assembly.
Claim 14
Dependent Claim
52 words
The combination of claim 7 wherein said work holder comprises a guide member into which the ram means is retracted, and a die assembly fixed to the frame within which the top opening is formed, said die assembly having a slot through which the sheet material is inserted intersecting the top opening.
Claim 15
Dependent Claim
39 words
The combination of claim 11 wherein said guide member encloses the ram means within a bore diametrically smaller than the top opening to form a seating shoulder supporting the cutter means in a retracted position within the die assembly.
