Abstract
Methods, systems, and apparatus, including an apparatus that is a rail anchor comprising a head, a tail, and a belly section. The belly section comprises a top surface, a bottom surface, and two side surfaces. Each side surface comprises a contact-bearing surface area. The head comprises a bend along a length of the head. The tail comprises a notch. Each contact-bearing surface area has a surface area of at least 3 square inches and is adapted to extend at least 1.5 inches downward from the top of a railroad track crosstie along a side of the railroad track crosstie.
Claims
exact text as granted — not AI-modified1 . A rail anchor, comprising:
a head, a tail, and a belly section; wherein said belly section comprises:
a top surface, a bottom surface, and two side surfaces;
wherein each said side surface comprises a contact-bearing surface area;
wherein said head comprises a bend along a length of said head; wherein said tail comprises a notch; wherein each said contact-bearing surface area has a surface area of at least 3 square inches and is adapted to extend at least 1.5 inches downward from the top of a railroad track crosstie along a side of the railroad track crosstie.
2 . The rail anchor of claim 1 wherein said contact-bearing surface area has a surface area of about 5.5 square inches.
3 . The rail anchor of claim 1 wherein:
said head also comprises a widened top surface along a length of said head; and
said tail also comprises a widened top surface along a length of said tail.
4 . The rail anchor of claim 3 , wherein said widened top surface along the length of said head and said widened top surface along the length of said tail are formed from a same substantially rectangular cross section of material that forms said belly section.
5 . The rail anchor of claim 4 , wherein said rectangular cross section of material has a vertical dimension of about between 1.0 inches to 1.3 inches and a horizontal dimension of about between 0.5 inches to 0.75 inches.
6 . The rail anchor of claim 5 , wherein said rectangular cross section of material has a vertical dimension of about 1.156 inches and a horizontal dimension of about 0.65 inches.
7 . The rail anchor of claim 1 , wherein said belly section has a substantially rectangular cross section along a length of said belly section.
8 . The rail anchor of claim 1 wherein each of said side surfaces of said belly section includes a vertical dimension that exceeds a horizontal dimension of said top surface of said belly section.
9 . The rail anchor of claim 1 wherein said contact-bearing surface area of each of said side surfaces is adapted to contact said side of said railroad track crosstie.
10 . The rail anchor of claim 1 wherein the rail anchor, comprising said bend along said length of said head and said notch in said tail, is adapted to engage opposite sides of a railroad track rail.
11 . The rail anchor of claim 10 , wherein a jaw opening in said bend along said length of said head has a dimension of about 0.5 inches and said notch has a height of about 0.15 inches.
12 . The rail anchor of claim 1 , wherein said belly section comprises at least a belly section bend between said head and said tail.
13 . A method of manufacturing one or more rail anchors for a railroad track structure, comprising the steps of:
for each of said one or more rail anchors:
feeding a bar into a press, wherein the bar is oriented so that a height of a cross section of the bar is greater than a width of the cross section of the bar;
forging each end of said bar to form, at each end, a shorter and wider profile, wherein a middle section of said bar is left having an original profile;
forming a rail anchor shape;
forming a jaw and a tail on said rail anchor; and
forming a notch near said tail;
quenching said one or more rail anchors; cooling said one or more rail anchors; and tempering said cooled rail anchors; wherein each rail anchor has a contact-bearing surface of at least 3.0 square inches and is adapted to extend at least 1.5 inches downward from the top of a railroad track crosstie along a side of the railroad track crosstie.
14 . The method of claim 13 , further comprising the steps of:
inspecting said rail anchors; testing said rail anchors; and packaging said rail anchors.
15 . The method of claim 13 , wherein said quench tank comprises oil.
16 . The method of claim 13 , wherein the said head, said tail, and said belly sections are formed at a temperature in a range of about 1900 degrees Fahrenheit to 2300 degrees Fahrenheit, and said cooled rail anchor is tempered at a temperature in a range of about 700 degrees Fahrenheit to 1000 degrees Fahrenheit.
17 . The method of claim 16 , wherein said head, said tail, and said belly sections are formed at a temperature of about 2100 degrees Fahrenheit, and tempering said cooled rail anchors occurs at a temperature of about 800 degrees Fahrenheit for at least one hour.
18 . A method of installing a rail anchor on a railroad track structure, comprising the steps of:
anchoring a rail with a rail anchor comprising a contact-bearing surface area adapted to contact a railroad track crosstie; wherein said rail anchor comprises a head, a tail, and a belly section; wherein said belly section comprises a top portion, a bottom portion, and two side surfaces; wherein each of said side surfaces comprises said contact-bearing surface area; wherein said contact-bearing surface area has a surface area of at least 3 square inches; and wherein said increased bearing surface area is adapted to extend at least 1.5 inches downward from the top of the railroad track crosstie along a side of the railroad track crosstie in said railroad track structure.
19 . The method of claim 18 wherein said contact-bearing surface area has a surface area of about 5.5 square inches.Cited by (0)
