Specification of Letters Patent.

Patented Oct. 27,1914.

Application filed August 16, 19112.vr Serial No. 715,429.

To all whom it may concern I Be It known that l, CHARLES J. GRIFFITH, a citizen of the United States, residing at fSt. Louis, Missouri, have invented a certain new and useful improvement in Railway- Crossings, of which the following is a full, clear, and exact description, such as will enable others Skilled in the art to which lit pertains to make and use the same, reference being had to the accompanying drawings, forming part oit' this speciiication, in which Figure l' is a plan View of a pair of inte-` gral crossing rails constructed in accordance with my invention. Fig. 2 is an elevational view partly in section taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged cross sectional view taken on the line 3 3 of Fig. 2. Fig. 4i is an enlarged sectional view taken on the line 1 1 of Fig. l. Fig. 5 is an enlarged cross Sectional view taken on the line 5 5 of Fig. 1. Fig. 6 is a plan view of a crossing frog constructed in accordance with my invention. Fig. 7 is a plan view of a turnout rail Section constructed in accordance with my invention. Fig. 8 is an enlarged cross sectional view taken on the lines 8 8 of Figs. 1 and 6.

My invention relates to new and useful improvements in railway crossings of thLx type shown in my Patent No. 1,049,575, issued January 7, 1913, the principal object of my present invention being to construct a railway crossing wherein the crossing rails are formed integral with each other in order toprovide a very strong, rigid, and sub- Stantial structure, and the rail members of which crossing are of hollow triangular shape in cross section, thus providing a wide base that will readily resist all side Strains and stresses, and the material forming the body portions of the rails being so disposed as to obtain the greatest possible strength with a minimum amount of material.

By my improved construction a crossing can be produced at less cost than a crossing of ordinary construction owing to the reduced amount of material used together with the absence of bolts, rivets, and like fastening devices, and my improved crossing has greater strength and rigidity than an ordinary type of crossing owing to the peculiar construction of the rails and the disposition of the metal therein.

A further object of my invention is to provide simple means on the ends of the integral crossing rails wherein ordinary railway rails may be readily attached to the crossing rails. v

To the above purposes my invention consists in certain novel features of construc-L tion hereinafter more fully described and claimed.

, Referring by numerals to the accompanying drawings, A `designates the crossing rails, the same being formed integral with each other and each rail comprises a base plate 1, a pair of upwardly extending inclined webs 2, the upper' ends of which are united and formed integral with said upper ends is a ball 3. n

Formed yintegral with the side of each ball 3 is an upwardly curved longitudinally extending flange-guard 4, rand the space 5 between this guard and the ball of the rail forms the flange track traversed by the flanges of the car wheels.

The base plate 1 and the webs 2 'are compa-ratively thin and vbyxreason oftheir triangular arrangement a very strong and subf stantial hollow base is formed for the crossing rails which arrangement readily withstands. side stresses and vibration.

Formed integral with the ends of the crossing rails are base plate extensions 1a and web extensions 2a and these extending portions serve as points of attachment for ordinary lrailway track rails B, and in order that said ordinary rails can be positioned between the web portions 2a the sides ofthe base flanges of the ordinary track rails are cut away as shown in Fig. Sink order that the parts can be readilyassembled.

The ordinary rails are fixed to the exteny sions 2a by means of bolts or rivets 6. Where hollow triangular rails are used as track rails extensions 7 are formed on their ends and these extensions enter the hollow end portions of the crossing rails and are attached thereto by means of bolts or rivets 8 (see Fig.

In Fig. 6 I have shown a frog crossing constructed in accordance with my invention and in Fig. 7 is shown a turnout rail.

My improved construction enables me to form a railway crossing having great strength and rigidity and a crossing thatk will materially reduce pounding and jarring resulting from the vibration due to the passage of car wheels over the crossing. vBy forming the crossing rails integral all nuts, bolts, and like fastening devices which are ordinarily used in fastening crossing rails to each other are dispensed with.

It will be readily'understood that minor changes in the size, form and construction of the various parts of my improved device may be substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:

l. The herein described railway crossing comprising crossing rails formed integral with each other, each of which crossing rails comprises a base plate, a pair of inclined webs integral with the base plate and a ball integral with the upper ends of said webs the base plateand webs of each crossing rail being extended at the ends thereof to receive and serve as points of attachment for track rails.

2. The hereindescribed railway crossing comprising crossing rails formed integral with each other, each of which crossing rails comprises a base plate, a pair of inclined webs integral with the base plate, a ball in tegral with the upper ends of said webs, and a flange-guard integral with said ball the base plate and webs of each crossing rail being extended at the ends thereof toreceive and serve as points of attachment for track rails.

3. A railway crossing comprising integral crossing rails that are hollow and of triangular shape in cross section, and hollow triangular extensions on the ends of said rails adapted to receive the ends of adjacent track rails;

4. rlphe hereindescribed railway crossing comprising crossing rails that are formed integral with each other, each of said rails comprising a base plate, a pair of inclined webs, a ball on top of said webs, and hollow triangular extensions at the ends of the crossing rails, which extensions are adapted to receive the end portions of adj acent track rails. Y

5. A railway crossing composed of intersecting crossing rails, the bodies of which are hollow and of triangular shape in cross section, balls integral with the tops of said hollow body portions and hollow triangular extensions at the ends of said rails, which extensions' are adapted to receive the end portions of adjacent track rails.

6. A railway crossing comprising hollow intersecting rails, the openings through which rails are triangular in cross section, and hollow triangular extensions of the ends of said rails for the attachment of the ends of adjacent track rails.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses, this 14th day of August, 1912.

CHARLES J. GRlFFITH.
