f Another and equally important ob ectpf the invention is to provide the gate with novelly constructed and "ar1'angecl trips which, when engaged by the'wheels of rolling stock, will serve toniove the V gate to opened and closedlpositions The invention consists, furthermore, in the novelarrangements and combinations of the'partsof the gate, as well asfin the details of the construction of the same, all of which iwillbe more fully described in the following specification and'then finally em:

posed 'bolts 3, which as will be noted, serve to pivotally support the usual cross arms 4: and 4, the rear ends of which are weighted as at 5 in order that the same will normally assume their open or substantially upright positions. It of course will be noted, that the arms 4 are mounted off-center, the longer portions thereof being of lengths sufli'cient "to span the space between the spaced uprights 1. and 2. Brackets 6 are secured to certain of the sides of the uprights 1 an'd2 and serve to receivethe oppositely disposed free endsof the arms 1, thus affording an efi'ectu-al stop therefor whereby to limit the downward movement of the same and alsoefl'ectually bracing the same. fPulleys indicated by the numerals 7 and 8 are supportedin the lower portions ofthe several hollow uprights 1 and 2 adjacent slots 9 and 10 formedtherein, in order that cables, hereinafter described, may bepassed thereoven Spaced gate actuating trips 11 and 12 are pivotedto the sides 'of one of' the rails of the track T asat-13 and have their upper portions formed substantially V-shaped, While the lower'portions thereof are bent downward for connection with the arm closing cables 14 and15, through contractile coil springs 16., As will be noted, these closing cables 14: and 15 are'passed over spaced pulleys '17 supported upon suitable brackets arranged in, proximity to the roadway and track and are connected with thegate arms 4 and 4, respectively. Spring arms 18 haV-f ing certain of their ends bent upwardly as at 19 are positioned adjacent the lower ends of the trips 11 and*12 and are adapted to be engaged therewith subsequently to the y de- Ipressingoftlie trips by engagement ofthe wheels of the rolling stock therewith. In this way, it will be readily understood that the trips 11 and 12 when once depressed will be maintained in such positions until released, by means hereinafter described. Releasing cables 20 and 21 are connected to the arms 4 and 4: respectively, and extend downwardly through the hollow uprights 1 and 2 over pulleys 8 and about other pulleys 22 having connection with the ends of the oil"- set portions 19 of the spring arms 18. Hence, when the trip 11 is depressed by the wheels of the rolling stock passing thereover, the same will act through the closing cable 14 to cause the closing of the arm 4: supported on the upright 1. As the rolling stock proceeds over the-track T, the wheels thereof will be engaged with the second or positionby, meansof the cable 15.v Simuh taneously with the closingof the arm 4, the

. first arm 4 will be permitted. to .movcia-toitsi open position, since the arm 4 will impart a, pull to the releasing cable-21', thus disenr gaging the end port-i0na19' of thearm 18 from the lowerwendflof, the trip 11. (Dbviously, this operation is: reversed when the trip 12, is-first depressed. v

Qther trips 23 and24-are pivotally mount:- ed on the rail of the; track T carrying; the trips 11 and 12, ,at points vdistant; therefrom and have'their upper portions formed substantially V-shaped while the lower! ends are bent; downwardly and engaged by short releasing; cables 25. and 26, which as will be noted,v are extended into engagement with the angular ends 19 of the arms18. The releasing}; cables 20 and 26 are,- extended through a. guide 20 arranged adjacentthe trip 12 and the cables 21 and, 25 are, extended through a guide 21?" arranged ad.- jacent theltrip 11. The rolling; stockv upon proceeding farther over the track T will engage either one: of, the tripss23; 01224:, depressing the same and causing t.heend,,1:9 of the spring arm.18.connectedtherctoto be moved OlllJ'Ofi engagement with itsrespective end of the trip, 11 or 1 2,thereby releasing saidtrips and permittingthe arms 4 con nectedthereto to be immediately moved to their upperor-o-pen positions. I

From the foregoing, it-is believed that a full understanding of the construction and operationof my improved gate is afforded. However, in this connection, it, is to be noted that the spring 16 serves to, prevent. the transmissionrofexcessive vibration, or, abnormal strainsto the cables 14, and 15. and to thepivoted arms 4 connected thereto; Further, it is to-be alsounderstood that the pulleys 7 and 8 maybe of: the double sheave type, if desired,thus rendering the construction more compact.

The various trips 11,12, 23"and 24 may be arrangedcn the track T at any desirable distance apart, such as conditions or preference may dictate, providing that su lGient space is afi'orded to insure proper functioning: of the-same:- during; the passage of the rolling stock thereoven Manifestly, the construction shown is 0e.- pable ofl'considerable modification and such modification; as is; Within; the scope. of my c1aims,\I,1 consider within, the spiritof; my invention: Y I i lhclaimr,
