in connection with'the drawings accompanying and forming a part hereof, is a specification.

This invention relates to means whereby a trolley will automatically lay a track over an open space, and after the trolley has traveled over said trackthe track will auto matically be removed and said open space restored. I

Among the objects of the invention is to obtain a construction whereby, when a rail suspended track is crossed by a like rail suspended track at an angle, an opening in said tracks will be automatically filled by a track sectionfby a trolley ap} proaching said opening, on either track and in either direction. An additional object is to obtain, in a suspended rail track which extends through a'doorway, an open space through which the door to said door way may be moved to a closed po'sitlon, and when said door is 'ln'fan open position a trolley may travel in either direction on the trackand will automatically lay a track across (said open space and continue its travel along the track; and when trolley has travelled over andbeyond said auto matically laid track section, said tracksection will automatically resume its initial and normal position relativeto said open space. Additional objects are to obtain a construction of the kind named which is simple in construction, comprising few parts, economically made, and not liable to break or get out of order. Y

In installing a construction embodying this invention duplicatemembers are placed at the ends of the. tracks atjthe open space which is to beautomatically bridged by one or the other thereof, determined by the direc tion in which the-trolley is travelling on said tracks, and certain parts, on the other one of said members aremovable, and are actuated by said'trolley, to permit the trol by o pass on in, continued travel along the tracks, 7

The bolt b is extended upward to and through the plate C, on one side of the opening and through the plate C on the opposite, side of said opening, and the chairs B, B, respectively, are suspended by said" bolts from said plates.- 5'' represent nuts which are mounted on the respective bolts 6', ,b, and are turned down on to the plates 6, b, to rigidly hold said plates on the lower flanges of the rails A, A, respectively. crossovers of the track theqmembers C, C are preferably continued across the opening in the track, as is indicated by broken lines. C, Fig. ,1; but where the track passes through a door way the portion ofsaid members indicatedby the broken lines C is omitted, so as to present no obstruction to a door being closedthrough said opening.

A two part member normally in a ve r' tical position, one of said parts pivotally ifs part, abutments on said parts arranged to co-act to permit rotation of said track sections in one direction onthe pivots thereof, and to prevent rotation in the other, direction, and means to .yieldingly maintain said two part members normally in vertical po'sitlon with sa1d opening not bridged and to permitsaid rail sections to turn pivotally away from said opening, the; rails of said rail sections arranged to obstruct the trolley wheels of trolleys approaching said opening and to be turned, together with said first named memberinto a substantially horizontal plane and bridging said opening by the advance of said trolley, all combined as setrforth.

5. In a suspended rail track provided with an opening, members pivotally mounted adjacent to said opening, means to yield, ingly hold said members normally in a sub stantially vertical position, track sections pivotally mounted 0n said members, means to prevent said track sections turning in one direction on said pivots and to permit them to turn in an opposite direction, said track sections arranged to obstruct the rails approaching said opening and, together with said first named members, to be turned by trolley wheels of a trolley approaching said opening from said normal position to a substantially horizontal position bridgingsaid opening, and said track section arranged to be turned on the pivot thereof by the Wheels of a trolley leaving said track section, to
