Abstract
Abstract This invention provides apparatus for slowing down the forward speed of severed head pieces or sample pieces issuing from a rolling mill at rolling mill speed, so that the severed pieces may be removed from the main processing line. This is achieved by providing a separate channel or track which may be switched into and out of the main processing line to receive the severed pieces, with the switching channel being in the form of a loop. Because of this shape, the forward speed of the pieces is reduced rapidly in a switching channel requiring very little space, not only because of its shape, but also because the curved course of the channel increases frictional engagement with the severed pieces, as opposed to a straight switching channel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
98 words
Apparatus for decelerating the forward speed of head or sample pieces of bar-shaped rolled material, and having a brake flute in which the material to be decelerated is brought to a near or complete halt from rolling speed, characterized by a. said brake flute is configured in the shape of a loop for deflecting said head or sample pieces from their original path of movement into planes substantially parallel with that original path of movement, said flute being positioned substantially parallel to said path; and b. means for moving said flute laterally into and out of said path.
Claim 2
Dependent Claim
98 words
Apparatus for decelerating the forward speed of head or sample pieces of bar-shaped rolled material, and having a brake flute in which the material to be decelerated is brought to a near or complete halt from rolling speed, characterized by a. said brake flute is configured in the shape of a loop for deflecting said head or sample pieces from their original path of movement into planes substantially parallel with that original path of movement, said flute being positioned substantially parallel to said path; and b. means for moving said flute laterally into and out of said path.
Claim 3
Dependent Claim
27 words
Apparatus according to claim 1, further characterized by a. a plurality of individual interchangeable brake segments; and b. said segments being connected together to form said flute.
Claim 4
Dependent Claim
59 words
Apparatus according to claim 2, further characterized by a. each brake segment being comprised of selectively a brake surface for receiving round, and square or flat profile pieces; and b. said round profile receiving surface and said square and flat receiving surface in each segment being positioned side by side, in the direction of lateral movement of said flute.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 1, further characterized by a. the entrance to said flute being funnel-shaped.
Claim 6
Dependent Claim
22 words
Apparatus according to claim 1, further characterized by a. drive means in said flute for moving pieces received therein through said flute.
Claim 7
Dependent Claim
23 words
Apparatus according to claim 2, further characterized by a. the braking surfaces of said plurality of segments being comprised of gray cast iron.
