Furnace crown means and method

a broad base flange parallel to said narrow attaching flange and

• 3. a T-rail web which connects the two flanges, such that the T-rails form T-rail rows when placed end to end;
• b. bone and hanger device combinations each combination including a bone and a hanger device for connection to said T-rails;
• c. said bones including:
• 1. a T-rail attachment end with an opening for attachment to said T-rail,
• 2. a hanger attachment end with a hole for attachment to said hanger device and
• 3. a stem connecting the two ends;
• d. an ultimate support system capable of supporting the kiln crown sturcture including pipes for attachment of said hanger devices;
• e. layers of insulation supported by and evenly separating the T-rail rows;
• f. wherein said T-rails and said bones are made of suitable heat-resistant structural materials;
• g. wherein the improvement includes the following modifications:
• 1. said inverted T-rail is slotted forming slots along its narrow attaching flange, to allow for easier attachment and removal of the said bones, and stopper means forming stops to each side of the said slot such that the slot evenly divides the stops which thus allows said bones to be attached and positioned such that the said bones are evenly spaced upon said T-rail,
• 2. rigid insulation cases fitted securely and fully into the space formed between said bones, above and within the space formed between said layers of insulation and
• 3.

An attachable bone and inverted T-rail system for use in suspending a crown comprising:

• a. inverted T-rails which include:
• 1. a slotted narrow attaching flange,
• 2. a broad base flange parallel to said narrow attaching flange and
• 3. a T-rail web which connects the two flanges, such that the T-rails form T-rail rows when placed end to end;
• b. said bones including:
• 1. a T-rail attachment end with an opening for attachment to said T-rail,
• 2. a hanger attachment end with a hole for attachment to a hanger device and
• 3. a stem connecting the two ends;
• c. said T-rails including a narrow attaching flange with three distinct widths, consisting of a narrow width slot means no wider than the T-rail's web width thus allowing bone to be inserted along the T-rail, a middle width slide means slightly narrower than the width of the bone's T-rail attachment opening thus allowing the bone to slide along the said slide means, and a wide width stop means wider than the aforementioned bone's T-rail attachment opening thus not allowing movement of the bone past said stopper means.
