Application led october 22., 1911. Serial No. 655,856. i'

struction oi' railway gates of that general character which are automatically lowered at the approach of a train to a. crossing, and automatically raised after the train has passed the crossing.

The object of the invention is to provide an automatic railway gate which is coniparatively simple and inexpensive in its construction, which is positive and reliable in its operation, which will not be conetant-ly getting out of repair, and in which the various elements can be properly housed so as to be shielded from rain and snow.

`With these and other objects in view, the invention consists in certain novel combinations and arrangements oi' 4the parts as will more fully appear as the description proceeds, the novel 'features thereof being pointed out in the appended claims.

, For a `lull understanding ,of the invention, reference is to be had to the following 'description and accompanying drawings,

in which:-

Figure l is a transverse sectional view through a railway track having the automatic gates mounted upon opposite sides thereof. lFig. 2 is a plan vie'w of al crossing provided with the automatic gates, the parts being shown diagrammatically and the gates appearing in a lowered position. Fig. Sis' a plan view in which the various electric circuits are diagrammatically shown, the .various switches being inthe position assumed at that instant when the train has passed the crossing and the gates are to be raised.l Fig. t is a detail sectional view through one of the main casings and showing the gearing for raisingl and lower ingl the gates. Fig. 5 is va detail sectional View through one of the trip actuated switches which serve to actuate the mechanism for lowering the gates when a train approaches the crossing from either direction. Fig. 6 is asimilar view taken at right angles to Fig. l1" ig. 7 is a detail sectional View of the trip actuated switch which is:

utilized for setting the, mechanism in motion for raising the gates` after the train yhas passed the crossing. Fig. 8 .is a detail view oi' the switch which is actuated by the gates to stop the motor when the gates have. been either raised or lowered, and Fig. 9 is a diagrammatic view of the switch controlling one oli the motor circuits.

Corresponding and like parts are referredto in the following description and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the letter A designates a railway track, and B a road or highway which crosses the track. Gates C are arranged upon opposite sides ofthe railway track A, andvmechanism is provided whereby these gates are automatically lowered as a train approaches the crossing, and automatically7 raised as the tra-in leaves the crossing. A suitable bell would be provided, and means would be provided for sounding this bell for a suflicient time `prior to lowering the gates, so that there would heno danger of a vehicle or pedestrian being trapped between the' lowered gates.

Ne will first describe the specific manner of mounting the gates and the gearing for raising and lowering the same.

Each 'of the gates comprises a casing 1 whichv is preferably closed so as to exclude rain and snow, the said casing being mount.- ed upon :ibase 2 of concrete or other suitable in-aterialt. A transverse shaft 3 is journaled within the upper portion of the casing l and the ends of this shaft project beyondl the casingand have the usual gate irons 4f applied thereto. One end of each of the gate irons is weighted as at 5, while the opposite end thereof has the gate bar G applied thereto. `The shafts 3 of the t'wo gates on` opposite sides of the crossing are each suitably connected as by means 'oa chain and sprocket 7 to a' transverse shaft 8l which extends under tile trac-k -A and is suitably housed within a tubular' casing 9. The ends of this casing 9 are provided with suitable bearing members 10 within which the shaft is journaled. One end of the shaft 8 is connected by the gearing l1 to a motor 12 which serves to lower the gates, the said `:motor being Vmounted Wit-hin the adjacent casing l. The opposite end of the shaft 8 is connected by similar gearing 13. to a similar motor 14: which serves to raise the gates,

electromagnets, an operative connection between the two armatures and the movable switch element, a circuit including one of the electromagnets, means constructedfor actuation by moving a train for closing the circuit to energize the magnet, the said magnet operating to move its armature and thereby shifting the movable switch element to close the motor switch, an electric circuit including the opposite electromagnet, and means for automatically closing the circuit when the gate reaches the limit of its movement, the said opposite magnet being then energized and operating to move itsarmature and shift tlie movable switch .element to 4open the motor switch.

2. The combination of a gate, an electric motor geared to the gate, a motor circuit, a switch cont-rolling the motor circuit and formed with a movable element, a pair off electromagnets, a pair of levers, armatures mounted upon the levers and arrangedin cooperative relation to the respective electromagiiets, an operative connection between the levers and the movable switch element, a circuit including one of the electromagnets, means constructed for actuation by a moving train for closing the circuit to energize tlie magnet, the said magnet operating to move its armature and swing the levers so as to shift the movable switch element and close the motor switch, an electric circuit includingthe opposite electromagnet, and means for automatically-closing the circuitwlien the gatev reaches the..,limit of its then energized and operating to move its armature and swing the' levers to shift the movable switch element and open the motor switch.

3. The combination of a gate, a motor geared to the gate, a motor circuit, a switch controlling the motor circuit and formed. with a movable element, a pairof electromagnets, a pair of levers, armatures mounted upon the levers and arranged in coperative relation to the respective electromagnets, a` bar connecting the levers and having an Operative connection with the movable switch member, a` circuit including one of the electromagnets, means constructed for actuation by a` moving train for closing the circuit to energize the magnet,l the said magnet operating to swing the levers so as to move the movable switch element and close the motor switch, an electric circuit including the opposite electromagnet, means -for autonfiat-ically closing the circuit when the gate reaches the limit of it-s movement, the said opposite magnet being then energiz'ed and Aoperating to swing the levers to move the movable switch and open the motor switch.

In testimony whereof we aitix our signatures in presence of two witnesses.-
