RAILWAY-CROSSING.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed August 23, 1913. Serial No. 786,301.

To all whom it may concern:

Be it known that I, JOHN C. ENGSTRAND, a citizen of the United States, residing at Hegewisch, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Crossings,

of which the following is a specification.

The present invention relates to railway crossings and is designed to improve the construction of such crossings in order that passing cars may travel over a substantially smooth and continuous rail at crossings.

The invention is illustrated as applied to a single track railway, and the operative parts of the crossing are actuated by a car approaching in any one of the four directions.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles, but it will be understood that the crossing is adapted for use in many other forms at the intersection of the four rails of a railway.

Figure 1 is a plan view of a railway crossing equipped with my novel construction and mechanism. Fig. 2 is a plan view of the working parts of Fig. 1, the cover plates, etc., being omitted, and the track rails shown in dotted lines, while the guard rails are eliminated, for convenience of illustration.

Fig. 3 is a vertical, transverse sectional view of the crossing, taken on the line of one of the rails. Fig. 4 is a transverse sectional view of the rail of the crossing, the movable parts of the crossing being omitted. Fig. 5 is a plan View of one of the four sectional castings constituting a portion of the crossing. Fig. 6 is a side elevation of one of the rail heads that is fitted to a pair of castings as shown in Fig. 5. Fig. 7 is a side elevation of a rail end that is attached at the outer side of the crossing.

In the accompanying drawings wherein the preferred embodiment of my invention is illustrated, the crossing embodies four sectional castings as 1, 2, 3, 4. One of the sections is illustrated in Fig. 5, and will be described in detail, the description of this section being suflicient for the remaining three sections. Each section is formed with four arms as 5, 6, 7, 8, the arms 7 and 8 being at the outside of the crossing, and the arms 5 and 6 being at the inside of the crossing. The short arms 5, 5, and 6, 6, of the four corner sections are joined by rail sections, 9, four in number, each of which is formed with the web 10 adapted to fit into a socket portion 13 of the adjoining arms 5, 5, 6, 6, and the arms and web are fastened together by means of bolts 12 passed through alined perforations for the purpose. The longer arms 7 and 8 of each corner section are also formed with socket portions 11 in which a short rail section 14 of special form is seated, and in which the end of the track rail 15 is seated and the two parts are secured by bolts 12. It will be seen in Fig. 5 that the socketed portions 11 and I3 stop short of the center of the casting, in which a hole 16 is provided, and the heads of the rail sections 9 and 14 project nearer to each other than the web portions thereof which are secured in the socket members 11 and 13. In this manner, at each of the four corners of the crossing frame, a space is provided for a flanged post 17, each of which is revolubly secured in a base plate 18 and projects upwardly between the adjoining rail ends. The four posts are each provided with a rail head, as 19, 20, 21, 22 formed at the upper surface and flush with the heads of the rails and rail sections of the crossing and track.

The posts are revoluble synchronously, and are arranged so that the rail heads 19 to 22 are always in parallelism, and the posts are coupled up by the following system of levers. Supported upon a plate 23, located between the four castings 1, are a pair of large bell crank levers 24 and 25, pivoted on the central post 26. At their ends links 27 are pivoted to the arms of the levers 24 and 25, and these links are again pivoted, respectively, to the four push bars 28, 29, 30, 31. These push bars are each pivotally connected to a pair of revoluble posts 17 by means of pivot bolts 31, 32 which are passed through perforations in integral disks 33, 34 of each post, the bars having their ends located between the disks, as clearly seen in Fig. 3.

The large levers 24, 25, are oscillated on their pivots 26 from an approaching car through the medium of a pair of levers 33, at one side of the crossing, or a similar pair 34 at the opposite side, and while space prevents the illustration of the second pair of levers, it will be understood that such additional levers are used. These levers are pivoted to the rails at 35 and bear upon a pivoted angle lever 36 or 37 and the angle levers 36 and 37 are connected by a rod or bar 38. There are four of these rods 38 and .they lie alongside the rails of the crossing below the push bars 28 etc. Each. rod has a bell crank lever 39 pivoted thereto, and each bell crank lever, which is pivoted to the plate 23 at 40, is also pivoted to a link 41 which is pivoted at 42 or 43 to the large levers 24 and 25 respectively.

In connection with the crossing I employ the usual guard rails 44 within the crossing frame and for a suitable distance the guard rails 45 are extended from the crossing, braces 46 being shown to hold the parts in place, and removable plates 47 are also shown in Fig. 1 to hide or cover the operating parts of the crossing. In the drawings the crossing is set for the passage of a car from left to right or vice versa, and the movement of the parts will be obvious from an inspection of the drawings.

In operation an approaching car sets the crossing when its front wheels contact with and depress one of the pairs of depressiblc levers and through these depressible levers and connections the push rod is actuated. Through the levers 39the levers 24 and 25 are moved through the links 41, and the oscillating levers 24;, 25, move the bars 28, 29, 30, 31 through links 27, thus revolving the posts as will be understood. The movement of the posts may be limited by the presence of pins as 48. A vehicle passing in the intersecting direction will revolve the posts to desired position as will be understood.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination in a railway crossing with a rectangular frame composed of sections and each section having webs with tions and each section having webs withsocketstherein, ofrail members each having a head and web with said web located in adjoining sockets, and. revoluble posts with rail heads forming.continuations'ofa pair of rail members.

3. The combination a railway crossing with a frame composed of sections and each section havingwebs with sockets therein, of

rail members each having a head and web, and the webs of the rail members connecting said sections in pairst. The combination in a railway crossing with a frame having open corners and composed of sections and: each section having webs with sockets and rail members each having a head and a web, a revoluble postin each open corner having a rail head to form a continuation of the railwa tracks and means for revolving said posts.

5. The combination in a railway crossi-ng with four revoluble posts having rail heads to form continuations of the railway track, a pair of oscillatable leverspivoted in the center of the crossing, four bars connecting the posts in pairs,.di=rectlink connection between four bars and. said levers, and a second set of four levers each havinga link a connected to a bar and a link connected to one of the oscillatable levers.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN C. ENGSTRAND.
