- l object of the present invention is to provide an improved railway crossing comprising aplurality of metallic sections, supported on ties at asuitable height to form a surface in the same plane with the tread of the rails, the sections being adapted to be Vreadily placed in position or removed Without interfering with the rails.

Another object'of the present invention is to provide an improved railway crossingof theabove type Awhich maybe built at the factory, easily shipped to its destination and conveniently assembled on the job.

AA further object is to provide a railway crossing ofthe above type having meansfor insulating the sections from the rails sothat it will be impossible for electrical currents to pass from one rail to the other.

A yet further Object is to provide a railway crossing which will be eiiicient in use'and adapted for all kinds of traiiic, simpliiied in construction and durable in wear.

.With these and various other objectsin view,`the inventionmay consistof certain novel features of construction and operation, as will bemore fully described and particularly pointedout in the specification, drawings and' claims appended heretop A In the drawings,`vvhich illustrate an embodiment of the device and wherein like refere'nce characters are used to designate like partsf `Figure 1 is a cross sectional view taken transversely of the railroadtrack and showingthe construction of the present invention. Figure 2 isa top plan view of thestruc- )ture shown in Figure A j l Figure 3 is a detail sectional view showing the construction for insulating the sections from the rails.`

Referring to the drawings, it Will be noted that the present invention is adaptedto be associated with arailroad track of the conventional type, employing a series of transverse ties 10, upon Which are" supported in correct spaced relation the rails 11;A Any 1930. serial No. 444,181.

preferred means such as spikes may be employed for securing the rails 11 in place upon the ties.

The crossing` comprises a plurality of metallic plate sections of Which plates 12 are adapted to be located centrally of the crossing between the rails 11. The plates 12 are ycounterparts of each other, each being provided With a grooved edge portion 13 on one side, which portion is adapted to underlie the head of the rails 11. For supporting the plates 12 a plurality of supporting members `14 areprovided, which members are of channeled formation. These members rest upon the top of the ties and have secured to them by riveting or other means, the plates l2. Each plate preferably employs four of the channeled members for supportingit upon the ties. The central supporting member 15 of each plate has its channeled portion in facing relation with the channeled portion of the oppositely disposed member 15, each `member being lirmly secured to the ties 10 by suitable spikes 16 and in turn having riveted to them the plates 12 as described. In addition the channeled members 15 have riveted to their upper flanges a plurality of brackets 1,7 for purposes to be described. The riveting for securing the channeled members to their respective plates 12 is located at inf tervals as shown in Figure 2 by the rivet heads and at these intervals the centrally disposed channeled members 15 have secured to them the brackets 17.

Extending longitudinally ot the crossing and parallel with the rails there is provided a central beam 18 preferably for the purposes of the present invention.` comprisi ng a wooden beam and being secured to the cross ties l0 by centrally disposed spikes l5). lVth the chan nel members 15 secured in place and the lnackets 17 located at their proper intervals,

the Wooden beam 1S is thou adapted to be .located in position between the members 15 and 1s of a size to exactly iit within the space deiined by the members and so thus has boaringengagement against the brackets 17.

lVith the wooden beam firmly secured in place by the spikes 19 and the channel members l5 by their spikes 16, the brackets 17 will serve to provide a rigid support for the upper portion of the channeled members. Any thrust which maybe imparted to the plates 12 will be thus transmitted tothe channeled members andato the brackets 1,7, which in turn will transmit the same tothe central beam. lith the beam thus firmly secured totheties itis seen thatthe plates 12 and their supporting members form an extremely rigid construction. Y

' Disposed outwardly ot" the rails are apll proach plates 20, which plates vare counterpartsof each other being provided with one straight edge and a grooved edge 21 which has underlying` relation with the heads of the rails 11. rlhese app-roachplates are adapted to be supported. on the ties at substantially the same height as the plates 12 by supporting members 22, also of channeledforni. rlhe members 22 rest upon the ties 1 0 andhave the approach plates 20 secured thereto by riveting or other means. The outside supporting member is adapted to be secured to the tie by' a headed spike 23 as shown in g .Figure 1. These spikes are located in the ties 10 in a direction to not only lirmly secure the members 22 thereto but also to force the ap- `proach plates 20 in a'direction towards the rails 11 so that their- .grooved edge 21 will underlie the heads of the rails.

In assembling lthe construction at that particular location on the tracks adapted to rform va crossing orvehicular traffic, it is onlynecessary to locate the platest12 centrally of the roadbed so thattheir grooved edge 13 willV underlie theheads of the rails 11.' The plates 12 are of a width when properly located to allow insertion ot the centrically disposed Wooden beam 18. It is of course understood that previous to securing thebeam 18 in place it is necessary to firmly secure the supporting members 15 to theties and .to also locate in their proper position the brackets 17. With the central part of the crossing in assembled posit-ion the approach plates 20 can then vbe located on the outer side of the rails and secured in place by means of the spike-members ,23.

For forming a crossing, the plates 12 and approach plates 20 are provided with a pluralityof stuckup knobs 24 located in spaced positions on their upper surface. These knobs constitute: a

cheap and eilfective meansfor preventing skidding of the rubber tires otfautomobiles and furthermore has the advantage in that they do not injure the tires. i

For the purpose of allowing automatic operation of danger signals which isaccoinplished by causing a current to tiow'troin one rail to the other, it is necessaryto insulate thel rails from each other, otherwise signaling by.

this means would be impossible. To this end ythe groov'ed edges 13 and 21 ot the plates'12 and the approach plates 2 0 respectively are non-skidding surface for the tipped with a strip of insulating-material 25 as shown inFigure 3. This insulating strip is adapted to entendy the full width ol the crossing, thatis, from one end of the plates to the extreme other end. By the construction oi the present invention the grooved-edges of the plates Lterminate a short' distance from theirails 11V and therefore the plates 12 and 20 do not have contacting engagement with the rails at all. For' securing the strip of insulating materialr 251to the edges of theplates a clip oi steel 26 is provided ot U-shaped torni vadaptedto be ifitted upon the insulating strip and to have bearing engagement against the v rails. The steel clips 26 are provided at yintervals.throughout theY length of thecrossingpi'eferably-every two teet.V It is'thus seen ,that by means of the above construction the electric currents traveling in each rail 11 Will vbe preventedtroin vpassing from rail to raily by reason of the insulating strip 2.5, and also that the `steel clip serves to lirinly holdthe i insulation in placeas Well as forming a backing means for engaging the rails. i

It is tovbe understood that wedo not Wish to be limited by the `exact embodiment ot' the devicel shown, which is merely by :way ot illustration.. and not` limitation, asivarious and cated between the members, and means se-` curing said members and beam to the ties.
