Abstract

A bolted, rigid railroad frog assembly in which the wing rails are made in separate toe and heel portions. A cast manganese insert is positioned between toe and heel portions of the wing rails. The long point and short point rails abut the cast manganese insert and are connected to the heel portions of the wing bars. The cast manganese insert has a point filler, a main filler and wing rail extensions and is symmetrical about a longitudinally extending plane so that the insert may be inverted when one side is worn out.

[ 5 7] ABSTRACT A bolted, rigid railroad frog assembly in which the wing rails are made in separate toe and heel portions. A cast manganese insert is positioned between toe and heel portions of the wing rails. The long point and short point rails abut the cast manganese insert and are connected to the heel portions of the wing bars. The cast manganese insert has a point filler, a main filler and wing rail extensions and is symmetrical about a longitudinally extending plane so that the insert may be inverted when one side is worn out.

2 Claims, 8 Drawing Figures "Hill PATENTEU M18 28 E875 SHEEI 1 OF 2 RAILROAD FROG ASSEMBLY SUMMARY OF THE INVENTION This invention is concerned with a bolted, rigid railroad frog assembly and more specifically with a cast manganese insert for said assembly.

An object of this invention is to provide a longer wearing railroad frog assembly.

Another object is to provide a frog assembly in which the portions thereof subject to the greatest wear are formed separately and may be easily replaced.

Another object is a railroad frog having a replaceable insert which has identical surfaces on opposite sides so that it can be reversed when one side is worn.

Other objects may be found in the following specification, claims and drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated more or less diagrammatically in the following drawings wherein;

FIG. 1 is a top plan view of a rigid, bolted railroad frog assembly of this invention;

FIG. 2 is an enlarged perspective view of the cast manganese frog insert of FIG. 1;

FIG. 3 is an enlarged perspective view of a cast joint bar of FIG. 1;

FIG. 4 is an enlarged cross-sectional taken along line 4-4 of FIG. 1;

FIG. 5 is an enlarged cross-sectional view taken along line 55 of FIG. 1;

FIG. 6 is an enlarged cross-sectional view taken along line 6-6 of FIG. 1;

FIG. 7 is an enlarged cross-sectional view with parts broken away taken along line 7-7 of FIG. 1; and

FIG. 8 is an enlarged cross-sectional view taken along line 88 of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT A bolted, rigid railroad frog assembly 11 is shown in plan view in FIG. 1. Each frog switch assembly includes oppositely bent wing rails 13 and 15 each of which is divided into separate toe and heel portions 17, 19 and 21 23, respectively. A toe filler block 25 is positioned between the converging toe portions 17 and 21 of the wing rails 13 and 15. A long point rail 31 and a short point rail 33 converge between the wing rail heel portions 19 and 23 of the wing rail.

A cast manganese insert 41 is positioned between the toe and heel portions of the wing rails and abuts the ends of the long and short point rails. The insert is fastened to the wing rails by means of cast joint bars 43. The cast joint bars are formed with integral extensions 45 which are shown most clearly in FIG. 3.

The cast manganese insert 41 is shown most clearly in perspective in FIG. 2. It is symmetrical above a longitudinally extending plane and on each side thereof has a integral point filler 47, a main filler 49 and wing rail extensions 51. The main filler includes a portion 55 which projects beyond the wing rail extensions at one end of the casting and a projection 57 at the opposite end of the casting adjacent the base 59 of the point filler. The base of the point filler also extends beyond the rail wing extensions and is coextensive with the projecting portion 57 of the main filler. A flangeway 65 commences at the tip of the main filler projection 55 and divides at the point notch 67 of the point filler into a pair of flangeways 69.

FIG. 4 shows a view through the toe portions 17 and 21 of the wing rails along a line taken in front of the main filler projection 55. The wing rails are held together by a bolt 73 which passes through the projecting portion 55 of the main filler, the wing rail toe portions 17 and 21, and the cast joint bar extensions 45.

FIG. 5, taken along line 5-5 shows a cross-section through the one wing rail extension 45, the projecting portions 55 of the main filler and a wing rail toe portion 21. The flangeway 65 of the main filler projection 55 is also shown.

FIG. 6 which is a cross-section taken along line 6-6 of FIG. 1, shows a bolt 75 extending through cast joint bars 43 located on opposite sides of the cast manganese insert 41. The pair of flangeways 69 formed by the point notch 67 are also shown.

FIG. 7 is a view taken along line 7-7 of FIG. 1 and shows a bolt 77 extending through a cast joint bar 43, cast manganese insert 41, wing rail heel portion 23 and cast joint bar extension 45.

FIG. 8 is a cross-sectional view taken through the base 59 of the point filler, the extension 57 of the main filler and the wing rail heel portions 19 and 23.

When any one or more of the surfaces on one side of the insert 41 becomes worn, the insert may be unbolted, turned upside down and reinstalled in the frog assembly. Because the insert is symmetrical about a longitudinally extending plane, identical surfaces such as the point filler 47, wing rail extensions 51 and flangeways are provided on opposite sides thereof.

Whereas, the preferred form of the invention has been described and shown, it should be understood that there are modifications, alterations and changes which may be made without departing from the teachings of the invention. Therefore, the scope of the invention should be only limited by the claims attached hereto.

I claim:

1. A bolted, rigid railroad frog assembly including:

wing rails having separate toe and heel portions,

long point and short point rails converging between said heel portions, a cast manganese insert positioned between said toe and heel portions and separating said portions,

said cast insert including a point filler, a main filler and wing rail extensions, said point filler and said main filler extending longitudinally beyond said wing rail extensions to fit between said heel and toe portions respectively with said point filler abutting said converging long and short point rails,

a joint bar positioned on each side of said frog assem bly to connect said cast insert with said toe and heel portions of said wing rails, each of said joint bars having a center portion which is positioned in contact with a wing rail extension of said insert and cantilevered end portions which project from said central portion to engage said heeland toe portions of said wing rail positioned outwardly of said main and said point fillers, and bolt openings extending through said insertand said joint bars to receive bolts to fasten said assembly together.

2. The frog of claim 1 further characterized in that said cast manganese insert is symmetrical about a longitudinally extending horizontal plane to provide identical point filler, wing rail extension and main filler surfaces on opposite sides so that said insert can be in verted in said assembly when one set of surfaces is worn =8 i t t

Claims
