RAILROAD-GATE.

LMECIYFICATION forming part of Letters Patent No.'347,574, dated August 17, 1886.

Application filed June 3, i886.

T0 all whom, it may concern Be it known thatwe, HENRY CLUEVER., of the city and county of Albany, and State of New York, and NICHOLAS THELEN, of the city and county of Schenectady, and State of- New York, have invented a new and useful lmprovementjn RailroadGates, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

vFigure l is a plan view of our improved railroadgatepartly in section and parts being broken away. Fig. 2 isa side elevation of the same, the gate-posts being shown in section and parts being broken away. Fig. 3 is a sect-ional side elevation of the saine, taken through the linea: fr, Fig. 1.

The object of this invention is to provide railroad-gates constructed in such a manner tliat they Wiilbe closed by the wheels of an approaching train and opened by the wheels of a passing train, and which shall be simple in construction, reliable in operation, and not liable to get out of order.

The invention consists in the construction and combination of various parts ofthe railroad-gate, as will be hereinafter fully described and then claimed.

A represents the ties, and B the rails, of a railrcadtrack.

C are shafts placed upon the opposite sides of and at suitable distances from the crossing or other place where a gate is required. To the shafts C, at the inner side of a rail, B, are rigidly attached horizontally-projecting arms D, upon the uppersides of which rest project-ions E, formed upon or attached to the leversF. The ends of the levers F farthest from the gate are pivoted to supports attached to ties A in such position that the said levers will be struck and pressed downward by the flanges of the wheels of cars approaching the gate. The free end s of the levers F are bent away from the rail B, so that 'the flanges of the wheels of cars leavingI the gate will pass in between the rail and the said ends of the levers F, force the said levers aw ay from the said Serial No. 204,029. (No model.)

l rail, and pass along without operating the said levers.

The levers F are held in place at the side of the rail B by spiral or other springs, G, one end of which rests against t-he sides of the said levers farthest from the rail, and their other ends rest against and are secured to supports H, attached to ties A or set in the ground.

tance from the outer sides of the rails B, are attached horizontally-projecting arms l, to the free ends of which are attached the ends of wires or chains J, which pass over guide-pulleys K, pivoted to supports attached to ties A or set in the ground. From the guidefpulleys K the wires J pass to the gate-posts L, set in the ground at a little distance from the track and at the opposite sides of the crossing or other place to be guarded, where the said Wires J pass around guide-pulleys M,placed within and pivoted to the said posts L, and are attached to' the lower ends of vertical sliding bars N. The posts L are formed of two parallel upright bars or plates, kept at the proper distance apart by upright bars O, interposed between and secured to the said bars or plates. Upon the adjacent sides of the interposed bars O are formed lugs P,which are perforated to receive and serve as guides for the vertical sliding bars N. The upper ends of the sliding bars N are forked, and to them are pivoted small rollers Q, which rest against the lower sides of the pivoted gate -bars R, at a little distance from their pivoted ends, so that the said gatebars will be raised or opened by the upward movements of the said sliding bars N. Upon the sliding bars N are placed spiral springs S, the upper ends of which are attached to the said bars and their lower ends rest upon the lower lugs, P. The springs S must be of sufiicient strength to press the bars N upward with sufiicient force to raise the gate-bars R, and thus open the gates.

Around the uppei` parts of the sliding bars N are formed annular grooves T, in such positions as to receive the inwardly-bent forked upper ends of the latches U,which are pivoted at a little distance from their lower ends to lugs V, formed upon the lower parts of the bars O. The lower ends of the latches U are bent To the ends of the shafts C, at a little dishars IC, IseI 'asI to engage iantematiealiy :witlh near thatthe said :persenziwoiild hev liable to 'the' grooves'oi'tliefsadsliding'barsassoon zheranover.:fl @pnanwww fadowawardpnll uponthe'saidwireswillwithI l.lxfff;2:l'ldrawtiiezengagingiendsoithelsaidilateheszU,

NVith this construction, as a train of ears approaches the gate, the flanges of the enginewheels strike or press down thelever F,whieh rocks the shaft C at that side of the gate, and causes the wires J to draw down the sliding bars N,allowing the gate-bars Rte swing down by their own weight, closing the gate.
