Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
128 words
In bar conditioning apparatus, the combination comprising a first station including means for supporting a moving bar having a flat top surface, a relatively flat bottom surface and generally vertically extending side walls, the flat top surface and side walls meeting to form edges, and means for chamfering the edges of the moving bar, a second station in tandem with the first station and including means for supporting the moving bar and means for partially forming a predetermined radius on each chamfered edge of the bar, a third station in tandem with the second station and including bar supporting means and means for finish forming the radius and means in tandem with the third station for mechanically cleaning the surfaces of the bar before hot working the same.
Claim 2
Dependent Claim
128 words
In bar conditioning apparatus, the combination comprising a first station including means for supporting a moving bar having a flat top surface, a relatively flat bottom surface and generally vertically extending side walls, the flat top surface and side walls meeting to form edges, and means for chamfering the edges of the moving bar, a second station in tandem with the first station and including means for supporting the moving bar and means for partially forming a predetermined radius on each chamfered edge of the bar, a third station in tandem with the second station and including bar supporting means and means for finish forming the radius and means in tandem with the third station for mechanically cleaning the surfaces of the bar before hot working the same.
Claim 3
Dependent Claim
79 words
The apparatus of claim 1 in which the mechanical cleaning of the surfaces of the bar is accomplished by means of a horizontal surfacing station and a vertical surfacing station, said horizontal surfacing station comprising a pair of opposed wire wheels each of which engages the flat top surface and the bottom surface of the bar and the vertical surfacing station comprises a pair of opposed wire wheels each of which engages the vertical side walls of the bar.
Claim 4
Dependent Claim
15 words
The apparatus of claim 2 in which each of said wire wheels is fluid cooled.
Claim 5
Dependent Claim
39 words
The apparatus of claim 1 in which each radius is formed with a cutting insert which is provided with a tool included angle of between 81* and 83* 30'''' and a bar included angle of about 80 1/2 *.
Claim 6
Dependent Claim
117 words
In bar conditioning apparatus disposed intermediate a continuous casting machine of the wheel and belt type to produce a bar and hot working apparatus for hot working the bar, said bar having a flat top surface, a relatively flat bottom surface and generally vertically extending side walls, the flat top surface and side walls meeting to form edges, the combination comprising, first means for supporting a hot continuously cast moving bar produced by the casting machine while chamfering the edges thereof, second means in tandem for supporting the chamferred bar while forming a radius on the chamfered edges, and third means in tandem for mechanically cleaning the surfaces of the moving bar before hot working the same.
Claim 7
Dependent Claim
117 words
In bar conditioning apparatus disposed intermediate a continuous casting machine of the wheel and belt type to produce a bar and hot working apparatus for hot working the bar, said bar having a flat top surface, a relatively flat bottom surface and generally vertically extending side walls, the flat top surface and side walls meeting to form edges, the combination comprising, first means for supporting a hot continuously cast moving bar produced by the casting machine while chamfering the edges thereof, second means in tandem for supporting the chamferred bar while forming a radius on the chamfered edges, and third means in tandem for mechanically cleaning the surfaces of the moving bar before hot working the same.
Claim 8
Dependent Claim
59 words
The apparatus of claim 5 in which the radius on the chamfered edges is formed in two operations in tandem, the first operation comprising means for supporting the moving bar and means for partially forming a radius on the chamfered corners and the second operation comprising means for supporting said moving bar and means for finish forming said radius.
Claim 9
Dependent Claim
89 words
The apparatus of claim 5 in which the mechanical cleaning of the surfaces of the bar is accomplished by means of a horizontal surfacing station and a vertical surfacing station, said horizontal surfacing station comprising a pair of opposed wire brushes one of which engages the flat top surface and one of which engages the bottom surface of the bar, and the vertical surfacing station comprises a pair of opposed wire brushes disposed for movement toward one another on opposite sides of the vertical side walls of the bar.
Claim 10
Dependent Claim
13 words
The apparatus of claim 7 in which each wire brush is fluid cooled.
Claim 11
Dependent Claim
33 words
The apparatus of claim 5 in which the radius is formed by means of a tool having a tool included angle of about 82* and a bar included angle of about 80* 30''''.
Claim 12
Dependent Claim
46 words
The apparatus of claim 7 in which the wire brushes of the vertical surfacing station are carried at an angle corresponding to the degree of inward taper of the vertical side walls of the bar for tangentially engaging said vertical side walls of the moving bar.
Claim 13
Dependent Claim
46 words
The apparatus of claim 5 in which the chamfering radiusing and cleaning means are adjustably mounted for the application of a substantially constant force thereto with respect to the moving bar to provide for bar deviation from a bar pass line while maintaining effective operative functioning.
Claim 14
Dependent Claim
38 words
The apparatus of claim 5 in which the cutting insert for forming the radius is provided with a tool included angle within the range between 81* and 83* 30'''' and a bar included angle of about 80* 30''''.
