I In constructing a crossin device embodying the invention a. blocl; or supporting member is arranged to bee'ither held normally or to be ralsed'fiush with the top of: the track and to occupy notches or cut out portions therein usually provided for accommodating the flang s of, the wheels. These supporting membersaredesigned to be quickly and automatically removed from is a section the path of movement of any of the flanges rection across the crossing. At the same tlme that the supporting means is automatically removed in front of the flanges, the

supporting means directly in the athof.

' Patented Mar. 7, 1911 I of the wheels ofa train moving in eitherdi- I movement of the body of the whee is rigidly held in position, so as to form a con; A tinuous, unbroken track for the Wheels as'the f same pass over the crossing. In one form of my invention a pair-oi operatmg bars and a plurality of connect;

mg mechanisms, together with retractile springs, are used for causing the supporting members to be raised to their proper position at the proper time, and to be retracted or brought to their normal position when not in use. If desired pivotally ino'lmted supporting means may be used and springs for normally maintainin the same in osihon. Either the pre erred oi? mo ified ,forms of the device may be used, but in any event the means are. designed to cause.

a track to present an even surface for the passage of the wheels .thereover, regardless of whetheror not the same main line or the cross line. I

' In order that the invention may be more clearly understood an embodiment of the same is shown in the accompanying drawing's, in which- 1 indicates the rails of 2 the, rails of the cross line. The cross line rails 2 arecut; at 3 for permitting the pitssage of the fi nge of the wheels of cars on' main line rails l, whilemain line rails 1 are cut at 4 for fpermittin the free passage of the flanges o the whee s, of cars onthe cross line rails 2. The opening-3 is desied'to be filled by a su orting bar' 5, gdfiie the opening a is fill d yby-su portinsg' -bar 6. These supporting barsaan 6 are normally moved to their raised p sition as shownfin 1111 lines in Fig. 4., and are held in their upper position, as shown in full lines in Fig. 4, when a trainis passing over the respective rails. The supporting bar- 5 is held, in a raised position .when a train is? passing over the rails of the cross road while supporting bar -ti-isheld in a raised;

pass over the l the main line, and

by spring 7 more clearly shown in-Fig;

' The supporting bars 5 and 6 are lowered respectively by springs 7 upon the depress: in of flan e engaging bars 8, 9, 10 and 11 1V en the l anges of the wheels of cars mving over rails 1 engage either of the bars 8 or 9 supporting bar will'be and held in a depressed position,.so as to form a continuous unbroken rail for the cars and a free passage for the flange of the wheel. The same action is,'.oi course, true in respect to railv 2 and associated means for raising b21115; When the flanges of the wheels of the cars are removed from any of the bars 8 9, 10 or; 11 the respective bars are moved immediately to a raise'dpoi sition, whichwil-l cause the immediate rais-' ing of the supporting bars .5 and 6 to their raised or normal position." A car eomin' from any direction toward the crossing wil operate one of the flange enga lower one of the bars 5 or 6 61' forming a continuous rail in front of the ear; and will cause the lowering of the other supporting bar.

merely duplicated for the other rail, "both mechanisms operating independently of each other. The mechanisms are arranged so that lthe flange bars are normally in'an elevated' position, and the su porting bars 5 and 6 are normally in an e evated osition;

When a train passes over the tracks in either direction the mechanism on the trackover which the train passes is operated for lower- 1 ing the supporting barwhich is in the way ofthe flanges of said train, and as soon as the 7, train has passedthe lowered supportin bar is immediately raised and also the ange operated bars are raised. In mounting the flange operated bars 8, 9, 1 0 and 11 the same are provided with guiding members 47, which permit only an up' and down movement in order to cause a proper motion to be imparted to the various journal members and other moving parts. These iding members, if desired, may be omitte at the ends of the flange bars nearest the crossing as the flange bars may be made to act as a guide one or the other.

In Fig. '6 is disclosed a slightly modified form of the invention in which is disclosed same function as supporting bars 5 and 6,

F but to be mounted pivotally on a supporting journal 49, which journal is held in place in 1 an deslred manner, preferably by being connected with the rails of the track; A flat spring is secured in position in any-desired manner, and bears against the under surface of the base 52 of support 48, and is designed to return support 48 to its normal upright position, after having been forced therefrom by the flange of the wheel. This form of supporting bar normally fills the notch or opening rat thecrossing, .and remains in an upright position at all times, excet when moved from that position by the ange of a wheel mounted on either of the crossing tracks.

In Figs. 7 and 8 is disclosed a further modified form of the invention in which supporting bars 53 and 54 are provided which have the same function as supporting bars 5 and 6. Supporting bar 54 is pivotally V mounted upon a journal 55, while supporting bar 53 is pivotally mounted upon a journal 56. ,Journals 55 and 56 are awls 13 and 14 shown as supported by a bracket 57, but it will be evident that they may be supported by a plurality of brackets or in any other desired manner for sustaining properly the weight exerted thereon. Sup-- porting bar 53 is provided with a projection 58 which has connected therewith springs 59 and 60 arranged in opposition. Spring 59 is connected with bracket 61, and sprin 60 is connected with bracket 62. Springs 59 and 60 are of the same strength and are balanced so a'sto normally hold supporting bar 53 in a vertical position, but permit the same to be easily moved to one side by the flange of .a wheel passing over rails 2'. \Vhen a train passes over rails'l' support 54 will be moved to one side and support 53 willremain upright, so as to present a continuous track surface for the wheels of the train. Supporting bar 54 is constructed and provided with similar springs and associated parts as su rtin bar 53 and will therefore need no a itiona description.

In Figs. 9 to 11 inclusive is showna form of the invention somewhat similar to'that shown in Figs. 7 and 8. Referring more particularly'to these figures, 63 and 64 indicate supporting bars pivotally mounted on suitable ournal bars 65 and 66. Each of a the supporting bars 63 and 64 is formed with shouldered portions 67 designed to rest against supports 68 and 69 when considerable pressure is 69 have the upper ends formed arc-shaped with the-center of the are at a point coinrought to bear onthe respective \members 63 and 64. The members 68 and cident with the center of the respective jour- I nals 65and 66, so that the members 63 and a supporting bar 48 designed to have the 64 may easily turn upontheir journals, and yetslidingly engage the supports 68 and 69. The arrangement of the shouldered 67 and the supports 68 and 69 is o considrtions erable importance as these means practically I take all the strain ofi of the journals 65 and 66 when a train passes over the respective members 63 and 64. In construct- -'ing the members 63 and 64 the same are preferably formed almost circular in shape at the bottom part 70, to which is secured suitable cables 71 connected .with suitable springs 72 which normally hold the respective members 63 and 64 in the osition shown in Fig. 9. The crossing is a so provided preferably with a base plate. 73 for acting as a suitable support for the ends of the rails, and for the members 68 and 69.

In addition to plate 73, which is preferably constructed of metal,'the re are also a plurality of plates '74 arranged'to almost con tact with the portions 70 of members 63 and 64, so as to protect the operating parts of the device, and prevent foreign matter from passing to the lower parts of" the device. v v
