Application filed November 5, 1919.

To all whom it may concern:

Be it known that I, SAMUEL H.-FURRY, a citizen of the Unitedsstates esiding at Lancaster, in the county of F airfield and State of Ohio, have invented certain new and useful Improvements in Road-Crossings, of which the following is a specification.

This invention relates to improvements in track crossings and more particularly to railroad crossing construction embodying means for bridging the ties and aflording an efiicient and exceptionably durable road bed at railway crossing points, thereby eliminating the usual jolting of a vehicle moving thereover and also reducing the pull or draft to a minimum by reason of the gradual and even grade afforded and the elimination of prominent places or obstructions in the road l leretofore in the usual construction of concrete asphalt or wood crossings the ties of the railroad have usually been utilized to retain the structural elements of the crossing in position with the result that not only is the resiliency of the ties impaired but the continuous vibration eflected by the rolling stock ultimately injures and destroys the construction of the crossing, being transferred directly thereto. The present invention has for its purpose the provision of a crossing and approach thereto which will bridge the ties and consequently eliminate these disadvantages and furthermore the invention contemplates the construction of a reinforced crossing and approach which will be exceedingly durable and unlikely to become fractured or broken due to the jar or vibration set up by passing vehicles or trains.

Moreover the vibration effected by the rolling stock upon adjacent portions of the crossing has heretofore tended to disintegrate the plastic construction thereof and to this end auxiliary reinforcing means of an improved nature have been lncorporated in the present invention particularly at the edges of the crossing ad acent the ties.

Furthermore, the improvements in bridge a proaches as set forth in my prior Patent 0. 1,300,949, April 15, 1919 have beenincorporated with the present invention .to

form a unitary structure therewith affording an efficient and durable approach to the crossing which may be readily constructed at nominal cost.

With these and other objects in view the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claims appended hereto.

Figure 1 represents a plan view of the road crossing constructed in accordance with the invention.

:Fig. 2 represents a longitudinal sectional View along the road Way, taken transversely of the railway track.

Fig. 3 represents an enlarged fragmentary sectional view at right angles to Fig. 2.

Fig. 4 represents an enlarged fragmentary sectional view in the plane of Fig. 2 illustrating a modification of the invention.

Fig. 5 represents a fra mentary sectional view at right angles to Fig. 4: of the modification.

Referring more particularly to the drawings, a portion of the rise 1 of an approach tothe crossing 2 at the left side of F ig. 1 is filled with a plastic material the-lower end of which is provided with a pocket or gutter 3 to provide a drain extending transversely 1 of the road and into which gravel or loose rock 4 is placed, for an obvious purpose. I

desire that it be understood that the construction of the rise or approach constitutes the subject matter of my previous-patent above referred to and is merely shown here with by wayof illustration tobring out more clearly the cooperation between the prior patent and the present structure. Although in the present drawings, the plastic material of the approach 1 is shown as exposed to wear, it will be readily understood that a metallic covering also provided with cor'r'ungxto those illustrated in,

fgations correspondi the accompanying aw-ings may be applied to the surface of the roadway, when found desirable or necessary. Whether-the road is faced or covered with corrugated metal or not is clearly optional and such variations may be resorted'to as necessity or preference may dictate. The corrugations, however, are extremely desirable particularly in the peculiar V-shape illustrated in Fig. 1 as due to their utilization thedurability and efiiciency of the approach 1s materially enhanced.

The railroad in connection with which the present invention is primarily designed for use embodies the usual ties A upon which are arranged the rails B, the latter bein properly mounted upon the railroad bed more clearly shown in Fig. 3.

The crossing per se consists essentially of three parts or sections, the two end outer sections 7 and the center section 8. The outer or end sections are arranged outwardly of the track rails B whereas the center part or section 8 is interposed between the track rails, adequate space being provided between the track rails and the sections of the crossing to accommodate the flanges of the wheels of the rolling stock and also to prevent communication of the ,vibratory movement of the rails incident to the passage of trains thereover to the structure of the crossing and thereby preventing possibility of consequent injury to the structure of the crossing due to the disintegrating effect of such vibratory movement.

Each section of the crossing is preferably formed in a plurality of parts or dlVlSlOIlS, each part or division preferably being of such width to overlie two of the rallroad ties A, as suggested in Fig. 3, and their parts being separated or insulated from each other by asphalt or other yieldable materlal 10.

Metallic reinforcing elements 16 are ap-' plied to the edges of the crossing sections 7 and 8 at points adjacent the track rails to prevent premature wear of these port1ons of the crossing incident to the wearing effect of vehicles passin thereover and the space between the rein orcing elements and the crossing sections and the rails B is filled with asphalt or, other resilient materlal 16' to prevent water from findlng 1ts way beneath the crossing and havin a detrimental effect upon the railroad bed The center section 8 is supported, at points intermediate the ties A directly upon the railroad bed C and is maintained 1n spaced relation to the ties A by supporting Reinforcing bars 13' and 17 are preferably anchored in the plastic material of the crossing to increase the strength and rigidity thereof and to bind together the several parts of each section. The end outer sections of the crossing which are disposed outwardly of the track rails B are supported upon the arches 11 which latter are main tained in arched condition during the con struction of the crossing by retaining members 20 as illustrated in Fig. 3.

Referring to the modification of the invention illustrated in Figs. 4 and 5 the letter A designates the bed oftherailroad, which in this instance is built up between the ties 30 to a height slightly above the latter to provide an adequate support for the spacing members or supports 31' which are formed with corrugated upper portions 32 receiving and supporting a sectional corrugated covering 33 preferably formed of metal and having the terminals extended in spaced relation below the heads of the rails 34 to provide a space for the reception of the flanges of the wheels of the rolling stock. The supporting members 31 are arranged intermediate the track rails 34 and additional supporting members 35 are arranged outwardly of the track rails and support the corrugated metallic plates 36 which are extended into proximity with the approaches toflthe crossing (not shown) in Figs. 4 and 5. For the protection of the railroad bed against the deteriorating eflect of water, resilient fillers 37 are arranged between the terminals of the supports 31 and 35 and the rails 34. In this form of the invention the crossing is provided with a metallic covering which, in certain instances is extremely desirable and although no metalliccovering is shown as applied to the type of invention illustrated in Fig. 2, it will be understood that such covering may be readily applied thereto when necessary or desirable.

The covering plates 33 and 36 are preferably formed in" conveniently removable sections and have yieldably cushioning elements 33 interposed between the sections, as suggested in Fig. 4. At the right of Fig. 2 is shown a channeled connecting member 40 for joining an approach 41 constructed of brick or similar material with the outer section 7 of the crossing,

It is thought that the construction and purpose of the present invention is obvious from the above description and I shall dwell.

no further upon it; however I desire tocall particular attention to both the utilization of asphalt or plastic material as a cushioning medium and the fact that no portion of the crossing touches the ties, thus preventing impairment of the resiliency of the ties and disintegrating effect of the vibration of a portion of the crossing should the latter be subjected to the vibratory-movement of the track rails and ties incident to the passage of trains thereover.

I do not limit my invention to the specific structural details herein described and illustrated but desire that it be understood that various changes and modifications may be made therein Which come within the scope of the appended claims.

lVhat I claim is:

1. A road crossing for railways constructed and arranged to lie in spaced relation to the track rails and ties to prevent transmission of the vibratory movement of said rails and ties to the crossing.

2. A road crossing for railways constructed and arranged to lie in spaced relation to the track rails and ties to prevent transmission of the vibratory movement of the rails and ties incident to the passage of a train thereover to the crossing, and approaches arranged laterally of the road crossing.

3. A road crossing for railways having corrugations and constructed and arranged to lie in spaced relation to the track rails and ties to preventtransmission of the vibratory movement of the rails and ties to the crossing.

4. A road crossing for railways having transverse corrugations and constructed to lie in spaced relation to the track rails and ties to prevent transmission of the vibratory movement of the rails and ties to the crossing.

5. A road crossing for railways constructed and arranged to lie in spaced relation to the track rails and ties, and resilient cushioning means adapted to be interposed between the track rails and the crossing.

6. A road crossing for railroads constructed and arranged to lie in spaced relation to the track railsand ties to prevent vibratory movement of the latter from being transmitted to the. crossing, and resilient' cushioning means interposed between the track rails and the crossing.

7. A road crossing for'railways composed of a plurality of sections, and means to support the sections of the crossing in spaced relation to the track rails and ties.

8. A road crossing for railroads comprising a road structure, means to support the road structure independently of the track rails and ties, and resilient cushioning means adapted tobe interposed between. parts of the railway and road structure.

9. A road crossingforrailroads comprising a road structure, and means to support the road structure independently of the ties of the railway at points intermediate said tles.

10. A road crossing for railways comprising a road structure consisting of a plurality of sections, means to support the sections of "the road structure independently of the track rails and ties, and resilient cushioning means interposed between the sections of the road structure and'adapted to maintain said sections in spaced relation to parts of the railway.

In testimony whereof I afiix my signature hereto.

SAMUEL H. FURRY.
