RAILROAD-CROSSING.

Application filed January 20, 1919.

To all whom it may concern:

Be it known that I, STEPHEN BALKWILL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Railroad-Crossings, of which the following is a full, clear,

and exact description.

The present invention relates to railroad crossings, and the object of the invention is to provide a corner piece or section for a crossing which is integral so that the corner piece may be inserted in the crossing to form a part thereof, at the same time making the corner piece easily removable so that a new one may be substituted as occasion may require.

enerally speaking, the invention may be said to comprise the elements and combinations thereof, set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this specification, in which Figure 1 is a top plan view of a crossing embodying a corner piece of my invention; Fig. 2 is a section upon the line 22 of Fig. 1; Fig. 3 is a top plan view of a crossing embodying a modified form of my invention; Fig. 4 is a section upon the line 4.-4 of Fig. 3; and Fig. 5 shows a filler block construction.

The corner portions of a railroad crossing always receive the hardest usage and are subjected to a greater amount of wear than any other portion of the crossing, being subjected to wear by traliic in both directions over the crossing, and it is hence these portions which most frequently require renewal.

here the crossing is made up of rolled rail sections, the corner portion is usually made up of arms which extend at an angle with respect to each other. and each arm is usually made of two rails which are bolted to each other and secured to the adjacent portions of the crossing.

It is my purpose to make the corner member of a crossing as a cast integral piece, which is secured in position by the use of bolts, but which may be readily removed from the crossing when the corner member is worn out and a new one substituted.

The present invention is particularly applicable and useful in the matter of reclaiming rolled rail crossings which have been in Specification 01' Letters Patent.

Serial No. 271,996.

use, and in which the corner portions have become broken or worn to a degree necessitating renewal. Such crossings may be renovated and made available for considerable more service by merely replacing the rolled rail sections which ordinarily are used in forming a corner portion of the crossing, and replacing the same with an integral cast corner portion such as described herein.

In carrying my invention into effect in such a crossing as shown in Fig. 1, the corner member 10 is made up with arms 10 and 10". These arms may extend at any desired angle with respect to each other in accordance with the angle at which the tracks approaching the crossing intersect.

The arms adjacent their outer portions are recessed, as indicated at 10 and 10 in order to receive a rail with which the respective arms cooperate. Each arm 10 and 10 at the portion thereof ahead of the recesses just mentioned, is provided with an extension such as indicated at 10 in Fig. 2. This extension is so formed as to substantially fit beneath the head and above the foot of the rolled rail with which it cooperates, as, for instance, the rolled rail portion 11 and the rolled rail portion 12.

The extension also is formed with a groove such as indicated at 10, this groove being so formed that when the corner portion 10 is assembled with respect to the rolled rail sections with which it cooperates, the groove 10 forms with the head of such rolled rail section, a complete groove through which the flanges of traversing wheels may pass, and it will be readily understood that the head of the rolled rail forms a guide for the wheel flange to guide it along the wheel flange groove of the crossing.

Filler blocks 14: cooperate with the rolled rail portions adjacent each corner, and space the rolled rails which form the tread Patented May 18, 1920. i

In crossings made up entirely of rolled rails, the filler blocks in one line are continuous past the intersecting wheel flange ways. This filler block is frequently broken in usage. By the use of the integral corner member, the breakage of the filler block is eliminated.

In the crossing shown in Figs. 3 and at, the crossing member 15 is provided with arms 15 and 15 which arms at their extremities have notched out portions 15 and 15 for the same purpose as that which has previously been described with respect to Fig. 1. The corner member 15 is not provided with projections such as explained with respect to that shown in Fig. 1, but instead, the arms 15 and 15 ahead of the notched out portions are provided with grooves such as indicated at 15 From an inspection of Fig. t it will be seen that the rossing member and the rolled rails 16 and 17 with which the arms of the corner member cooperate, are separated from each other by means of filler blocks such as indicated at 18 which fit in the groove 15 Each filler block is provided with a groove in the upper surface thereof, which in conjunction with the head of the rolled rail and the side of the arm of the crossing member 15 provide a groove for the flanges of car wheels which may pass over the same.

The crossing member is fastened and secured to the crossing by means of bolts such as indicated at 19, which extend through the arms of the crossing member, the filler block, and the web of the cooper ating rolled rail section.

As shown in both Figs. 2 and 41, the crossing member is cored out so as to make a lighter section, effect a saving in the quantity of metal used, and make the corner member easier to handle because of lighter weight.

The arms of the corner member in each case form treadways for the car wheels passing over the same. Consequently they receive the greatest amount of wear. It is my purpose to manufacture this crossing of a long wearing metal, such as manganese steel, but it will be apparent that should these crossing members become broken in usage, or worn out, they may be easily removed and replaced, much more easily than the same result could be accomplished where an all rolled rail corner portion is used.

It is further clear that by the use of a corner ember such as shown in both Figs. 1 and 3, the connection between the corner member and the adjacent rolled rail sections is such as to permit of a limited degree of flexibility in usage, so that all the advantages inherent in the rolled rail crossing are preserved, and the advantages gained from the use of a cast metal corner piece which have before been enumerated.

'VVhile I have disclosed my invention as applied to .an all rolled rail crossing, it should be understood that other forms of crossing may embody in them the feature of the cast metal corner memberwithout departing from the spirit of this invention.

Having described my invention, I claim:

1. A railroad crossing having a corner portion which comprises a corner member formed as an integral piece having arms, the top portion of the arms serving as tread portions and rail sections extending parallel with the arms and with which the arms cooperate, means by which the said arms and rail sections are spaced to form intersecting wheel flange grooves, and means for securing the arms and rail sections to each other.

2. A railroad crossing having a corner portion comprising an integral corner member formed with arms, the top portion of the arms serving as tread portions, rail sections extending parallel with the arms and with which the arms cooperate, means lying between and cooperating with the said arms and rail sections whereby the arms are spaced from their cooperating rail sections and intersecting wheel flange grooves are formed, and means for securing the arms and rail sections to each other.

3. A railroad crossing having a corner portion comprising an integral cast corner member formed with arms, rail sections extending parallel with the arms and with which the arms cooperate, portions of said arms being formed with projections which are adapted to fit beneath the head and above the foot of the rolled rail sections which cooperate with the said arms, thereby providing a wheel flangeway between each arm and cooperating rail section, and means for securing the arms and rail sections to each other.

4L. A railroad crossing having a corner portion comprising a corner member formed as an integral piece and having arms, rail sections extending parallel with said arms and with which each of the arms cooperate, each of said arms being formed with'an extension adapted to fit beneath the head and above the foot of the rail section with which it cooperates, a partial groove formed in said extension, which groove with the head of the rolled rail section forms a complete wheel flange groove, and means for securing the arms and rail sections to each other.

In testimony whereof, I hereunto aflix my signature.

STEPHEN BALKWILL.
