- AppIicatibn filed. November 27, 1915. Serial No. 63,755.

To all whom it may concern: a y

Be it known that I, HARVEY H. Asnnw, a citizen of the United States, residing at Los Angeles, in the countyofLosAngeles and State of California, have invented certain new and useful Improvementsin Railway- Crossings, of which the following is a specification. a

This invention relates to improvements in a railway crossing and especially such as must be used where. tracks, crossing each other are ordinarily formed with considerable gaps or openings for the passage of the wheel flanges on the rolling stock of. the road. i a

It is an object of the invention among other things, to provide a crossing in which a substantially continuous and unbroken support will be offered the wheels of rolling stock no matter in which direction the travel may be.

It is also an object of the invention to provide adjustable wheel supporting elements for bridging the spaces between the main portions of the track at a railway crossing, means also being provided for the depression of said intermediate members when necessary to accommodate the flange of passing railwaywheelsh V It is a further object of the. invention to provide a railwa crossing with depressible members adapted to form continuous wheel supports between the parts of the crossing and to provide supportingmeans capable of being thrown beneath said depressible members for holding them in wheel supporting position. i

It is a stlll further object of the invention to provide a railway crossing with depressi ble members for completing wheel a supporting portions of the tracks at a crossing and to provide spring actuating supports; normally holding the said depressible members in wheel supporting position, means; being also provided for autoinatically throwing the supporting means outof supporting position so that the depressible members may yield under the action of. thewheel flanges.

With these and other-objects in. view,.tlie

invention comprises certain novellconstructions, combinations and. arrangements of parts as will be hereinafter more fully described and claimed. a

In the accompanyingdrawing forming part of thisspecification;

Figure 1 is a top plan view of a railway crossing embodying the features of the present invention.

Fig. 3 is a detail sectional view of the portion of the. switch mechanism showing a modified form of means for throwing the supports out of supporting position.

Fig. 4% is a top plan view of a modified form of a. railway crossing, in which the supports for the depressible sections are normally out of supporting position;

Fig. 5 is a vertical sectional view taken upon the line. a b ofFig. 4.

Fig. 6 is a fragmentary detail sectional View taken through one-half of the crossing and showing oneof the cradles depressed by the passage of car wheels. i Fig. Tie a perspective view of one of the cradles shown infull lines and a companion cradle shown in dotted lines together with some of the details of the crossing also shownin position. i y I .In the accompanying drawing preferred embodiments of the invention have been shown andthe details andfeaturesthereof will now be more specifically describedwith. reference thereto. In the accompanying drawing 5 and6 indicate fixed rails of a crossing, the said railsbeing shown at right angles to each other, though ofcourse, it will be readily understood thatthey may be arranged at various angles with respect to each. other without departing in the least from the spirit of the invention. The said crossing is also provided withintermediate wheel supporting members 7 and 8 adapted to bridge the space between the fixed portions 5 and 6 of the crossing. The wheel supporting portions 7 and 8 .are depressible .devices; which may. be termed cradles and have side bars 9 and .10 respec-; tively and wheel engaging end portions 11 and .12. These'side bars 9 and 10 and the actuatingarm 37 connected by a rod38 with a lever 39 which is similar to lever 86, whereby the members 14 may be manipulated manually when desired; The said levers may be provided with the usual notched segments and with a spring actuated pawl or bolt for holding the lever in' its adjusted position, as for instanceasshown in Fig. 3.

In the modified form shown inFig. 4:, for instance, the depressible interlocking track sectionsmay be free to descend under the action of the wheel flanges, the supporting" members in this instance being normally out of supporting position instead of in supporting position as in the form of device shown in Fig. 1. With this form of the de vice also the depressing of one of the cradles upon the approach of rolling stock, operates immediately to move the supporting devices beneath the other cradle, so as to hold the track sections firmly in elevated position beneath the treads of the wheels. Thus the crossing of this modified form may be provided with wheel supporting sections 4% and 15 forming pants of cradles 46 and 47 and being fitted within the crossing tracks l8 and 49. Immediately beneath the wheel supporting sections 44; and 15 are rocking supporting members 50" and 51 which are pivoted or otherwise movably supported upon the base of the crossing so that they may be brought vertically beneath the said wheel supporting sections 1st or 4:5. The upper edges of the said supporting members are provided with flanges 52 for limiting the inward movement of the said supporting members. Springs 53 connect the upper edges of said supporting members with standards 5st which rise from the base of the crossing, the said springs normally keeping the supporting members in their open or outwardly rocked positions as shown in Fig. 5 of the drawing. The structure of the device is also such that when one of the cradles is depressed by the flanges of car wheels, the rocking supporting members of the other cradle will be thrown beneath the wheel supporting sections to be used by the car. For this purpose hinged trip pieces 55 are mounted at the lower edge of each supporting member and are provided with inwardly projecting, cradle engaging lips 56. The outer ends of the trip members 55 extend upwardly outside the supporting members 50 and 51 and springs 57 are interposed between the two members, the structure being such that when the cradle is depressed upon the lips 56 the outer end of the trip pieces 55 will be forced against the springs 57 sufficiently to carry the supporting members 50 and 51 into vertical position beneath the wheel supporting track sections. The structure is thus such that when the car wheels strike the cradle 47 and depress it, the supportingmeinbers 50 will be thrown inwardly immediately and beneath the track sections the outer sides of the wheel supporting track sections 414 and 45 so as to cover the joint between the supporting members and the said track sections, against the falling of dirt or grit into the working parts of the mechanism and interfering with its operation.

The perspective view illustrated by Fig. 7 shows the interlocking cradles with notches or openings 68 provided, which allows one cradle to iinpend the other and permit ample space for the up and down movement of the parts when wheels are passing over the crossing. The interlocking cradles are deposed parallel tothe crossing tracks and when in operative position form a continuous and noiseless crossing.

The construction of the railway crossing may be modified in various ways, the sup porting members 13 may be constructed to swing from the inside instead of from the outside as shown, and it will thus be evident that many of the minor details of construction maybe changed in embodying the invention in practical form and many mechanical equivalents may be substituted for the parts described and shown all within the spirit and scope of this invention.

What is claimed is:

1. A railway crossing having transverse sections adapted to bridge the space between the adjacent ends of crossing road ways, movable members adapted to be rocked back and forth beneath said transverse sections, movable means adapted to move said rocking members whereby flanges of wheels may operate the said members in one direction,
