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.

The invention relates to improvements in railway crossings and other intersecting rails.

The object of the present invention is to improve the construction of railway crossings and the like and to provide a simple, practical and comparatively inexpensive device adapted to afi ord continuous treads-and continuous flange receiving grooves at street railway crossings and other points of track intersections of street and other railways whereby the injury incident to the contact of the wheels of the rolling stock with the ends of the rails will be entirely eliminated and the cost of the upkeep of a railroad greatly reduced.

A further object of the invention is to provide rotatable frog members having spaced tread portions and intervening flange receiving grooves and adapted to be turned in clockwise and counter-clockwise direction for arranging the grooves and the tread in alineznent with the grooves and treads of the rails of either track to form continuations oi the same.

Another object of the invention is to en able the frog members to be rotated so that separate tread surfaces will be presented .to the intersecting rails whereby the wear on the frog members willbe uniformly distributed over both of the tread surfaces;

The invention also has for its object to provide electrically controlled means for simultaneously rotating the frog members atthe four corners of a crossing and for looking the" said frog 'members in eitherof their positions. I p

With these and other "objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter described, illustrated in Specification 01' Letters Eatent.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention as applied to a railway crossing 1 designates rails arranged in pairs at right angles to each other and connected at their ends to corner bearing plates 2 each is a diagrammatical view, illusing plates. The inner attaching means comprises lugs or flanges 4 and arranged in pairs and spaced apart to receive the web 6 of the rails 1 which are sheared off at theirends to form projecting bottom flanges 7 that extend into recesses 8 of the corner bearing plates.

The projecting

flanges

4 and 5 which are approximately inverted L-shaped in cross section as clearly illustrated in Fig. 3 of the drawings are riveted or otherwise secured to the webs 6 of the mile 1 against which they are fitted. The outer attaching means for securing the outer rail sections 3 to the corner bearing plates consist of progecting

flanges

9 and 10 spaced apart to receive the webs of the rail sections which are sheared off to leave projecting bottom flanges 11 for extending into outer bottom recesses 12 of the bearing plate 2. i The

flanges

9 and 10 are substantially the same as the flanges 4. and 5 with the exception that the latter are slightly longer than the

outer projecting flanges

9 and 10. The corner bearing plates extend over the projecting bottom flanges of the

rails

1 and 3 and the said rails are connected at each of the corner bearing plates by a bottom connecting plate 13 to which the bottom flanges of the said rails are riveted or otherwise secured. The projecting flanges of the corner plates are cut away at 14 to aflord access to the rivets 15 or other fastening devices and after the 1 parts have been assembled filler blocks 16 are secured in the said recesses 14 as clearly illustrated in Fig. 2 of the drawings. Each of the connecting plates 13 is arranged upon a tapered or beveled compression plate 17 interlocked with the corner bearing plate and connecting plate by pins 18 arranged vertically and piercing the projecting bottom flanges of the rails, the connecting plate 13 and fitted in

sockets

19 and 20 in the corner bearing plates and the compression plate. The base'or compression plates 17 are riveted or otherwise secured to tie bars 21 extending longitudinally of the rails 1 from one point of intersection to the other and fastened at intervals to the bottom flanges of the said rails by rivets 22 or other suitable fastening devices and also secured to the said rails and the connecting plates by the rivets 15. The rivets 23 which pierce the crossed or overlapped ends of the tie plates or bars 21 and the base plates 17 have their heads countersunk in the latter as clearly as shown in Fig. 2 of the drawings. Any other suitable fastening means may of course be employed for securing these parts together. The terminal portions'of the tie bars or plates 21 are angularly bent as shown at 24 to conform to the configuration of the beveled edges of the base plate 17 and the construction forms a solid truss like structure and rigidly connects the parts together so that it is unnecessary to place a tie ,or similar support under the adjacent ends of the rails of the crossing. The corner bearin plate is of irregular rectangular shape an the bottom connecting plate which extends outwardly beyond the side faces of the corner bearing plate is provided in its projecting portions with spike receivmg recesses or openings 25 for the reception of suitable fastening means for securing the crossing in position. The crossing is provided at each of the rails with a flange way or groove 26 formed by longitudinally disposed guide plates 27 preferably arranged in pairs and connected by an angularly disposed portion 28 fitted against the adjacent side face of the corner bearing plate. The guide plates which are spaced from the adacent sides of the rails 1 by filler bars 29 preferably extend to the centers of the rails l midway between the corner bearing plates 2 as clearly shown in Fig. l of the drawings but the guide plates may be of any desired length as will be readily understood and they are secured to the rails 1 by rivets or other suitable fastening devices which pass through the guide plates, the rails, and the filler bars. The filler bars which are preferably made in sections as shown to facilitate casting and assembling the parts are provided in their bottom faces or edges with recesses or grooves 30 to receive the heads of the

rivets

15 and 22 which secure the tie bars or plates to the bottom flanges of the rails. Guide plates 31 are also located at the other side faces of each of the corner bearing plates as clearly shown in Fig. 1. These plates 31 have terminal attaching portions and angularly disposed connecting portions, the attaching portions being secured to the adjacent rail. The terminal portions of the plates 31 form outer. grooves 32 for guiding the flanges of the wheels and the attaching portions of the said plates 31 have the flanges 9 interposed between them and the rails.

Each of the corner bearing plates is provided in its upper face with a cylindrical bearing recess 01 socket 34: receiving a circular rotary frog member 35 provided with a flange way or groove 36 adapted to be arranged in alinement with the flange ways or grooves of the intersecting rails to form a continuation of the grooves or Ways for safely guiding the flanges of a wheel at the crossing. The rotary frog member is provided at opposite sides of the groove 36 with tread faces 37 which are arranged in the same horizontal plane as the tread faces of the heads of the rails and fixed tread plates 38 are suitably secured to the corner bearing plates and are located between the sheared portions oi the rails and the rotary frog member as clearly shown in Fig. 2 of the drawings. By this construction a conill anai tinuous tread surface and a continuous flange way or groove is provided at each intel-section of the rails so that all hammering of the wheels of a car or the like at intersecting rails is entirely eliminated.

By this construction all jar, vibration and pounding of the rails at a crossing or other intersection is prevented and in ury to the rails and the rolling stock from such pounding is eliminated and the cost of the upkeep of a railroad greatly reduced. Each of the rotary frog members is provided with a con trally arranged depending stem 39 extending through a central vertical opening 40 of the corner bearing plate and piercing the base plate 17, the connecting'plate and the overlapped terminals of the tie plates or bars. The stem is provided at its lower end with a threaded portion 41 to receive a nut i 'diate of their ends with 42 and it has a squared portion 43 on which is mounted a gear element 44. The gear element which has a rectangular opening 45 to receive the squared portion 43 of the stem is secured to the latter by a cotter pin 46 and it has an arcuate edge provided with spur teeth 47.

The gear elements 44 of the rotary frogs are actuated by oscillatory arms or bars 48 and 49 disposed diagonally with relation to the crossing and provided at their outer ends with

gear elements

50 and 51. The

gear elements

50 and 51 are substantially in the form of racks, the teeth of the gear element 50 of the oscillatorybars or arms 48 extending outwardly from cnlar ed terminal portions of the said arms or ars. The other set of arms 49 are rovided intermed flecting bands 52 which arrange the body portions of the said arms 49 below the plane of the other arms 48 and enable the said arms or bars 49 to extend beneath the stem upon which the coacting. gearing elements are mounted. The arms or bars are provided at their outer ends beyond the stems with vertically disposed flanges 53 having inwardly projecting spur teeth constituting the gear elements 51. The gear elements of the stems contiguous to the gear elements 51 are arranged reversely of the gear elements of the other stems in order to mesh with the inwardly projecting teeth of the gear elements 51 of the arms or bars 49. This arrangement efl'ects a rotary movement of some of the frog members clockwise and other of the frog members counter-clockwise when the arms of

bars

48 and 49 are oscillated in the same direction and a different tread surface is presented to each of the tracks of the inner section so that neither one of the said surfaces of the rotary frog member is subjected to all of the Wear incident to the travel over the crossing, The water collecting in the bearin sockets or recesses 34 is drained from the by substantially annular grooves 54 located beyond the bearing faces of the said sockets and communicating with a passage 55 having a tapered or flaring outlet and communicating with openings (not shown) in the connecting plate and the base plate to permit the escape'of the water draining from the bearing socket or recess. By this arrangement of the grooves, the bearing surfaces of the sockets or recesses 34 are not materially reduced and a maximum bearing surface is afi'orded.

The inner ends 56 of the oscillatory arms or bars '48 and 49 are arranged in horizontal recesses 57 of an enlarged top supporting portion 58 of a vertical rotary support or pivot 59 having upper and lower journals or pivot portions 60 and 61 and set in a bearmg 62 of a bottom bearing plate 63. The recesses 57 are tapered at their inner ends and the ends 56 of the oscillatory arms or bars 48 and 49 are correspondingly shaped. The side walls of the recesses 57 are extended above the upper faces of the arms or bars 48 and 49 and are provided with undercut or dove-tail grooves 64 which receive tapered laterally beveled'keys 65 which are secured in interlockedrelation with the rotary support or pivot 59 by bolts 66 piercmg the keys the arms orbars 48 and 49 and the enlarged upper portion 58 of the rotary pivot or supp course used. I

The base plate or'bottom bearingqplata ill) throughout the various portions oflthe con-71 struction but any form of bolt may bg of; act" 68 is mounted upon horizontal beams 69 'provided at their end portions withupwardlyf extending arms 70 arranged verticallyvand provided with outwardly extending attachiie' ing terminals 71. The outwardly extending 7 terminals 71 are secured by suitable fasten? ing devices to the lower faces of inwardly proyecting supporting portions 72 0f the contiguous connecting plate. The upper journal or pivot portion 60 is mounted in an opening 73 of an upper bearing plate'74 and is reduced to form a shoulder 75 which spaces the upper bearing plate from the upper faces of the keys '65 which retain the oscillatory arms or bars in the recesses of the pivot or rotary support 59. The upperbearmg plate is bolted or otherwise secured to open approximately rectangular supports 7 6,- each preferably consisting of a single piece of metal bent to form spaced sides and a connecting top portion, thelower terminals 77 of the sides being bolted or otherwise secured to the bottom bearing plate 63. These open supports 76 arch the oscillatory bars or its arms 19 and permit the necessary movement of the latter. The oscillatory arms or bars are supported at their outer portions by transversely disposed plates 7 8 slidably receiving the said arms or bars 48 and secured to the upwardly extending portlons of the frame bars or members 69 and provided with opposite shoulders 79 which limit the oscillatory movement of the arms or bars.

One of the oscillatory arms or bars as is provided with a thickened portion 80 having recesses 81 in its lower face and oppositely beveled at 82 at opposite sides of the recesses to present inclined faces to a pair of spring actuated latch bolts 83 adapted to lock the oscillatory bars or arms in each of their positions. The recesses 81 are located at opposite sides of the thickened portion 80 of the arm or bar 18 and the vertically movable spring actuated bolts are arranged to engage the recesses 81 when the said arm or bar is at the limit of its oscillatory move ment. The vertically movable latch bolts are guided in vertically

alined openings

81 and 85 in an approximately inverted U- shaped support 86 and a horizontal bar 87 having its terminals 88 bent downwardly and secured to the inner faces of the sides of the U-shaped support 86. The lower terminals 89 of the sides of the inverted U- shaped supports are bolted or otherwise secured to the upper face of a transverse sup porting plate 90 upon which are mounted vertically disposed electromagnets 91 adapted when energized to attract armature heads 92 carried by the lower ends of the latch bolts and located beneath the transverse bar 87 as clearly illustrated in Fig. 6 of the drawings. The latch bolts are actuated in their upward movement by coiled springs 98 interposed between the plate 87 and pins or keys 94 secured against movement on the latch bolts by passing through the bolt or other suitable means, but any other desired form of stop may be employed for engaging the upper ends of the coiled actuating springs. The upper engaging ends of the latch bolts are provided at their inner sides with beveled faces 95 to enable them to be readily depressed by the oscillatory arm or bar and they also have beveled faces 96 at their outer sides to enable them to engage or project slightly into the recesses 81 of the oscillatory arm or bar before the latter has reached the limit of its movement and the latches will positively engage the said arm or bar and efi'ectively prevent the same from accidentally being thrown backwardly through contact with the shoulders 79 of the guide plates 7 8. This insures the lock ing of the oscillatory arms in proper position at the end of each movement. The electro-magnets 91 which are bolted to the horizontal plate 90 are insulated therefrom by pieces 97 of wood or other suitable material attaching portions 102 bolted or otherwise secured to transverse plates 103 and insulated therefrom by pieces 104 of wood or other suitable material. The electro-magnets 99 are also connected and braced at the back by plates 105 having angularly disposed end portions and an integral central connecting portion as clearly illustrated. in Fig. 1 of the drawings. The movable electro-magnets are provided with field pole plates 106 having upper horizontally disposed attaching portions 107 bolted or otherwise secured to the lower faces of the oscillatory arms or bars 48 and insulated therefrom by pieces 108 of wood or other suitable material and also from the fastening means for securing the parts to the oscillatory bar or member. The field pole plate 106 of the movable magnet is arcuate and its arc cooperates with the arc of the field pole plate of the stationary magnets so that in the oscillatory movement of the arms or bars the field pole plate 106 of the armature movable magnet moves toward and from the field pole plates of the stationary electromagnets which have double windings and which are wound to a north pole and a south pole so that in the operation of the crossing the field pole plate of the armature magnets will be repulsed by the field pole plate of one of each pair of stationary electro-magnets and attracted by the field pole plate of the other electro-magnet.

Mounted upon the inverted U-shaped support 86 are

contacts

109 and 110 consisting insulators 111. The insulators 111 are secured in suitable supports or brackets 112 of approximately Y-shape composed of spaced sides and a connecting portion from which depends a centrally arranged stem. The stem pierces the top of the support 86 and is threaded for the reception of a nut as clearly shown in Fig. 6 of the drawings. The contact plates or

pieces

109 and 110 which are designed to be connected with signal light wires are arranged in pairs at opposite sides of the support and the contact plates 110 which are of greater length than the contact plates 109 are resilient and are adapted to be sprung into engagement and electrically contact with the plate 109 whereby one ofthe signal light circuits will be closed when the oscillatory bars or arms are in each position.

The thickened portion 80 of the oscillatory arm or bar 48 carries an actuating or circuit pending sides located at the side edges of the thickened portionpf the oscillatory baror member 48 and the said sides are adapted to flex the contact 110 a. and force the same into engagement, with the contacts 109.

in one direction by the energizing of, the stationary electro-magnets and the movable Y electro-magnets the. latch bolts are with? drawn by the energizing of the latch operating magnets 91 and as soon as the latter are deenergized by the cutting ofi of the current the spring operates to force the latch bar's upwardly into their engaging position.

, The stationary magnets 99 are each provided with windings a and b and which windings extend in opposite directions so that the north and south poles thereof can be reversed by sending the electrical current first through one winding and then through i The movable magnets 100 are the other. each provided with asingle winding 0 having their south poles disposed adjacent the stationary magnets 99.
