RAILWAY-CROSSING.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed November 25, 1916. Serial No. 133,824.

To all whom t may concern:

Be it known that we, JOHN W. BURNS and IVILLIAM BEACH, both citizens of the United States of America, and both residing at Los Angeles, county of Los Angeles, State of California, have invented a certain new and useful Railway-Crossing; and we do hereby declare the following to be a full, clear, and exact description of the, invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway crossing, and it may be said to consist in the provision of the novel and advantageous features and in the novel and improved construction, arrangement, and combination of parts as will be apparent from the description and claims which follow hereinafter.

The main object of the invention is to provide a novel and improved construction whereby upright slidable blocks are automatically operated by car wheels and adapted to fill the gaps between the main rails and the crossing rails so as to obtain the effect of continuous rails and thereby avoid the shock, jar, noise, and wear which ordinarily results :from carwheels passing over open gaps between the main rails and the crossing rails.

Further objects of the invention are to provide a construction of the nature specified which is comparatively simple in character, strong and durable, economical to manufacture, install7 and maintain, effective and convenient to use, and which can be applied to existing railway crossing without much change, trouble or expense.

Other objects and the advantages of the invention will be apparent to those skilled in the art from a careful consideration of the following description of the preferred form of the construction embodying the invention, taken in connection with the accompanying drawings in which- Figure 1 is a broken plan view showing a railway crossing having the invention applied thereto; F ig. 2 is an enlarged broken cross sectional view taken on the line 2 2 of Fig. 1; Fig. 3 is a broken cross sectional view of the railway crossing taken on the line 3 3 of Fig. 2; Fig. 4 is a broken view showing the manner of operation of the construction; Fig. 5 shows side, end, and plan views of one of the gap blocks; Fig. 6 is a plan view of the gap blocks mounted on the bar, and'Fig. 7 is a of the same.- I

In the description of the construction similar parts are designated by like reference characters. f

The main rails 8 and the crossing rails 9 may be of any suitable form; those shown being formed with a head having a groove 10, a base 11, and a web 12 connecting thev head and base.

As seen more clearly in Figs. 2 and 3, adjacent ends of the main rails 8 are connected by the plates 13 which are suitably secured to the web 12 of said rails. plates 13 is suitably arranged a pivot 14 on which is mounted the central portion of a bar 15 which is disposed obliquely against the beveled ends of the adjacent main rails 8. Angle plates 16 and 17 and straight plates 18 and 19 adapted to guide the pivoted bars 15 may be suitably mounted on the webs 12 of the main rails 8 and the crossing rails 9. The webs l2 of the main rails 8 and the crossing rails 9 are also preferably connected by angle plates 20 which are suitably fasbroken elevational view On each of the SOE tened to said webs 12. On the end portions f of each of the bars 15 are mounted the lower ends of the upright blocks 21 which are fitted movably in the gaps 22 ordinarily eX- isting between the main rails 8 and the crossing rails 9. The pair of blocks 21 on each bar 15 are preferably arranged at right angles to each other as seen more clearly in Figs. 6 and 7, and they preferably havel their lower ends 23 cut away or pointed and arranged to bear on the upper part of the bar 15. lStops or shoulders 24 on the blocks 21 are adapted to engage the heads of adjacent rails to limit the upward movement of the said blocks, and stops 25 on the bases 11 of the adjacent main rails 8 and crossing rails 9 are adapted to limit the downward movement of the bars 15.

From the foregoing the operation and advantages of the construction will be evident to those skilled in the art. It will be understood that the flange 26 being of a greater diameter than the tread 27 of the moving wheel 28 will strike and move down one block 21 on the bar 15 and move the bar 15 to raise the other block 21 and have the latter close the gap 22 and have its top flush with the tops of the main and crossing rails 8 and 9. While the flange 26 is still in a position to bear against one block 21 the tread 27 strikes the other block 21. which closes the gap so that the wheel passes aeross the gap 22 as on a continuons rail and without the shock7 jar, wear, and noise that would result if the wheel passed over an open gap between the main and crossing rails.

The construction which has been particularly illustrated and described admits of minor changes and modifieations-wherefore the right is reserved to all such changes and modifications as do not depart from. the spirit and scope of the invention which is defined in the appended claims.

We claim:

l. In a railway crossing, the combination of main rails7 plates connecting adjacent ends of the main rails, bars pivotally mounted on said plates, crossing rails separated from the main rails by gaps, and upright blocks movably fitted in said gaps and having their lower ends bearing` on the bars suliistantially as and to etl'ect the purpose set forth.

2. The combination with a railway crossing having main rails and crossing rails and gaps between the main rails and the crossing rails, of plates connecting adjacent ends of the main rails, bars pivotally mounted on said plates and disposed obliquely to the ends of adjacent main rails, and upright Y Copies of this patent may be obtained for five cents each, by addressing the "Commissioner of Patents, Washington, D. C.
