EDWARD L. KISI-IPAUGH, OF CHATI-IAIVI, NEW JERSEY.

RAILWAY-GATE.

To all whom 'it may concern:

Be it known that I, EDWARD L. KrsnrAUcH, a citizen of the United States, residing at Chatham, in the county of Morris and State of New Jersey, have invented new and useful Improvements in Railroad-Gates, of which the following is a specification.

This invention relates to that class of railroad gates which are adapted to be operated automatically by passing trains; and it has for its objects to simplify and improve the construction and operation of this class of devices.

lVith these and other ends in view which will readily appear as the nature of the invention is better understood the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention, may be resorted to when desired.

In the drawings: Figure 1 is a diagram illustrating the relative arrangement of the improved gate and the operating mechanism for the same. Fig. 2 is a side elevation of one of the operating levers for closing the gates and related parts. Fig. 3 is a top plan view of the same. Fig. 4 is a side elevation of one of the operating levers for releasing the trigger mechanism to restore the gates to the normal open position. Fig. 5 is a sectional elevation of one of the gates.

Corresponding parts in the several figures are denoted by like characters of reference.

The gates A-A which are arranged to obstruct a crossing of the railroad track B are each composed of a pair of levers 6-6, the short arms of which are provided with count-erweights 7 tending to maintain the gate levers 6 normally in approximately vertical or open positions. The levers 6 6 of each gate are operatively connected with each other by means of a suitably guided flexible element such as a wire rope or cable 8 for the passage of which a suitably constructed tubular channel 9 is embedded in the ground, thereby insuring simultaneous Specification of Letters Patent.

operation of the gate levers. A bracket 10 extending from one of the posts 11 upon which the gate levers are pivotally supported carries a rack segment 12 meshing with a pinion 13 upon the proximate lever carrying shaft 14 which latter will thus be oscillated by the oscillatory movement of the rack segment 12 to open or close the gate according to the direction of rotation.

Suitably supported adjacent to one of the rails 15 of the track B, and at a suitable distance from the crossing protected by the gates, is a lever 16 provided adjacent to its free end with a downturned detlecting portion 17. The lever 16 is normally forced in an upward direction by a spring 18 so as to normally lie some distance above the head of the rail. rEhe spring supporting bracket 19 is provided with an upwardly extending flange 2O having lugs 21 serving to support springs 22, the opposite ends of which press against the lever 16 so as to hold the latter in contact with the rail, and to avoid accidental displacement. The lever 16 is connected by a Alink 22 with a suitably sup ported trigger lever 23, the free end of which engages a spring actuated trigger 24. rllhe lever 23 is connected by a suitably guided flexible element 25 with an arm or bracket 26 extending from the rack segment 12, and it may thus be actuated to open the gate. If the crossing is protected by more than one gate, the flexible element 25 may be equipped with a divergent branch 27 which is guided to the rack segment of the second gate, as indicated in the diagrammatic view, Fig. l. The operating lever may be disposed upon the track at any suitable distance from the gate that is to be operated, to enable such gate to be closed a suitable time prior to the passage of the train, and the gate closing lever 16 is preferably made of considerable length. For the purpose of automatically opening the gate, immediately upon the passage of the train, there is arranged adjacent to the rail 15, a suitable distance from the side of the crossing opposite to that at which the lever 16 is located, a second lever 28 supported in a normally raised position by means of a spring 29. The lever 28 has a downwardly extending arm 30 which is connected by a suitably guided flexible element 31 with the trigger 24 which may thereby be actuated to release the trigger lever 23.

It will be seen from the foregoing description taken in connection With the drawings hereto annexed, that When a train approaches the crossing guarded by the improved gate, the lever 16 will be depressed, actuating the trigger lever 23 which Will be engaged by the spring actuated trigger 24:, and Will be held by the latter in a depressed position; the trigger lever 23 being connected by the liexible element 25 with the gate actuating segment rack 12 which is operated to move the gate levers to a closed position. The train, after passing the crossing, engages and depresses the lever 28 which, being connected by the ilexible element 31 with the trigger 24;, actuates the latter against the tension of its operating spring, thus releasing the lever 23 which is moved upwardly by the spring 18 supporting the lever 16, thus releasing the rack segment 12 and permitting the gate levers to reassume their normally open position by the gravity of the counterweights 7.

It is obvious that this gate operating mechanism may be arranged to be actuated by trains approaching the crossing from either direction, and that the invention is applicable to double as Well as to single tracks. The operating levers 16 and 28 are actuated or depressed by the Wheel flanges of the locomotive as Will be readily understood.

Having thus described the invention, 'what is claimed is- 1. In a railroad gate, a counter-Weighted gate lever, a pinion connected therewith, a rack segment meshing With the pinion, a spring supported operating lever adapted to be operated by a passing train, a trigger lever, a link connecting the latter With the spring supported lever, a spring actuated trigger engaginglthe trigger .lever trigger actuating mechanism, and a suitably guided flexible element connecting the trigger lever With the gate actuating segment rack.

2. In a railroad gate, a counter-Weighted gate lever, a segment rack actuating the same, a spring supported operating lever, a trigger lever, a link connecting the latter with the operating lever, a spring actuated trigger engaging the trigger lever, a suitably guided flexible element connecting the trig' ger lever with the gate actuating segment rack, a'spring supported releasing lever having a depending arm, and a suitably guided flexible element connecting said arm With the spring actuated trigger.

In testimony whereof I afiix my signature in presence of tvvo Witnesses.
