i Application fiiea'nareh 5,1921. serial No. 449,816. ;f

To all whom it may concern ll/L-Birm and have inventedcertain new and useful Improvements 1n G0X1131I1L1O11S R'211lGIOSSHlgS, of which thefollowing 1s a spec ficatlon. j

This invention relates to ra1lroadcrosstermed a continuous rail crossing.

The principal object of he present invention is to improve and simplifythe general constructionof devices of this character.

A second object of the invention is .to provide an improved device which is capable of being applied to any existing railroad crossingto form the same into. a continuous rail crossing.

A third objectof the inventionis to pro-. 7

vide an improved form of such device where in the operation will at all times be positive.

A fourth object of the-invention is'to provide a device of this character of improved construction which may be connected bysimple means to a railroad gate orthe like so that it may be used for the intersections of street andsteam railways and otherzlike,

places. 1 V e With he above and other objects in view, as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of partshereinafter fully described, illustrated in' the accompanying drawings, and specifically claimed. 1 v

In the accompanying drawings, like charactersof reference indicate like parts in the several views, and: e I

Fig. '11 is 'adetail perspective adouble cam wedge used herewith. v

In carrying, out the. objects of the invention in the iorm herein described thereiis provided ateach corner of the crossing a casing, 10 having a bottom: 11.: From this the" other casing on alli four sides project lugs 12 whereto the ra1lsR may besecured by means of bolts :13. It' is to be noted that. the lugs 12 are so positioned as to bring the rails just to the top ofthe casing. The, sideslof this casing are slotted asat 14:, the outer sides of said slots being, alined withv theinner sides 1 I of the ralls Rso that provision is madeifor I the passagefrom' one rail-section to the other of the j wheels saidslots accommodating the bolts 15. are blocks 16 each forinedvin two parts for convenience in assembling the various .parts ofthe device. These blocks-16 are, provided with-vertically disposed vre- Held within the casing by cesses .17 having enlarged portions 18 at'the i 9 bottom. Slidable, verticallyin the recesses 17 are fillermembers lfi) which areof general inverted T-shape,- the heads .beingshown at 20, and each head being beveled as at 21.

Slidable on the bottomsof the recesses-.18'is i a. double camewe'dge22. :The filler-members 19'are arranged with their cam or wedge faces 21 in opposite directions and the camv wedge 22-is so loca'tedthat moving this cam wedge in one direction'forces one part of the V Y V wedge beneath one; of said filler members and 'movestheother part of thewedge from beneathlthe other filler member. Mo.vement in theopposite direction. will",--conv ersely,

permit lowering of the" first member and raising, ofjth'esecondL llnadditiontoI the vertlcal rece'ssesgl'? which in one ofthemem here 16 extends fclear;across-saidmember 7 to form a slot:in, alinement-with, twoofthe 1 slots 14: there-is also provided in the other filler member fslot 23 which'alines with the pair of slots 14;. The filler members 19 and slot justmentioned. 1 Furthermore the block the cam wedge 22 are so proportioned that with the cam wedge beneath one of the filler "members the topof that member will be raised to-the top of theslot thus making a continuous rail as can beolearly'seen Fig,

v 0 V I form hereinshown and'described, but it is 3. Of course when this particular member s 19 is depressed the other member will be V the T head of the respective filler member 19. The other arm of this bell crank lever 26 drops behind the square end-of the por tion of the-cam wedge which controls'the respective filler member. 'VVith this construction when the cam wedge is withdrawn from beneath the filler member the bell crank is positively rotated and positively forcessaid filler member downward.

Supported in suitable bearings 27 is a rock shaft 28 provided with a rock arm 29 hereby connectedby a rod 30 with any suitable opcrating device as, for instance, a railroad gate. On the rock shaft28 are also double rock arms 31and to each arm ofeacli don 'ble rock arm isiconnected a rod 32 which passes through 'a' suitable opening 33 in one of the filler'members and is connected' within the recess 18 to the cam wedge 22 whereby V to'operate the same. From this construction it will be seen that rocking the shaft 28 in one direction will forceall of the wedges 22 toward'the rock shaft 28 and thussimultaneously raise the filler blocks for filling the gaps over which train wheels must pass when driven on one pair of the tracks. Cor respondingly rocking ,theshaft 28 in the opposite direction will force these filler blocks downward and raise the others so that a train may pass wi'thout jar over the other rails. i

' There has thus been provided a simple and for the purpose specified.

It isobvious that minor changes may eflicient device of the kind described and made in the form and construction of this invention without departingrfrom'the material principles thereof It is nottherefore desired to confine the invention to the exact wished to includeall such as properly come 'within' the scope claimed.

Having thus described the invention, what is claimed as new, is: s 1. The combination with a pair of rails intersecting a second pair of rails; of blocks at the points ofintersection eachihavingfintersecting grooves in its upper surface arranged to accommodate wheel flanges, each of said blocks having apair of vertically disposed recesses opening upwardly into said grooves at the outer sides of the intersection, filler members slidable vertically in said recesses, and means to raise said filler members selectivelyto the level of the top of the rails.

2. The combination with a pair of rails intersecting a second pairof rails; of blocks at the points of intersection each having intersecting grooves in its uppersurface arranged to accommodate wheel flanges, each of said blocks having a pair of vertically disposed recesses'opening upwardly into said grooves at the outer sides ot the intersection,filler members slidable vertically in said recesses, and means to raise said filler members selectively to the level of the top of'the rails, said means operating simultaneously to depress the other filler member.

3. The combination'with a pair ofrails V intersecting'a second pair of rails of blocks 1 'at the points of intersection each having intersecting grooves-in its upper surface arranged to accommodate wheel flanges, each of said blocks having a pair of vertically disposed recesses opening upwardly into said grooves at the outer sidesof the intersection, filler members slidable vertically in said recesses, cam wedges selectively movable to raise said'members selectively, and means to operate said cam'wedges.

4. The combination with a pair of rails intersecting a second pair of rails; of blocks at the points of intersection each having inunder and from beneath said filler members tersecting grooves in its upper surface arranged to accommodate wheel'flanges, each of said blocks having 'a pair of vertically" disposed1 recesses opening upwardly into SZLlCl gIOOVQS at the outer sides of the intersection, filler members slidable vertically in said recesses, cam wedges selectively movable under and from beneath said filler members to raise said members selectively, bell crank levers operated by the movement of said cam wedges frombeneath the filler members and arranged to engage the respective filler member and force the same down ward, and means'to operate all of the wedges simultaneously.

In testimony whereof we aflix our'signatures. I
