novelty following a description containing an explanation in detail of an acceptable Ti form of the invention. v

V The objects of the invention are to furnish a device that will enable the motorists and others to know that artrain is actually about to pa'ss a level crossing and thereby 15 eliminate the danger of not seeing the train in sufficient time for stopping the vehicle; p

to save lives and loss of property by the erecting of barriers that will ooincidently close and open before and after the passing p I v p of said-pivots sliding in "the slot 3t inlsaid' 70 29 of the trains across the highway; todevise V a gate that will operate with equal satisfaction in the wintry weather as well as in the summer; to avoid complicated parts and simplify the constructionso as toreduce the 23 cost of production and facilitatethe operation; and generally to provide a railway level crossing gate that will be durable in construction and efiicient in its operation.

In the drawings Figure'l is a vertical sectional view of the box disclosing the operating mechanism and gate.

Figure 2 is a vertical sectional view at right angles to the sectional view shown in anism.

Figure 3 is a view of the gate extended to shut off the road.

Figure 4: is a plan view of the bearing bracket for the rocker arms.

Like numerals of reference indicate corresponding parts in the various figures. Referring to the drawings the boX enclosing the operating mechanism of the, gate is indicated by the numeral and contains the bracket 11 in its upper portion and which is firmly secured to the box wall 12.

The bracket 11 has the bearing

members

13 and 14 for the upper rod 15 and the lower rod 16 supporting the rocker arms 17 and 18 respectively, I

The rocker arm 18 suspends at one end the 1 weightv37 which is supportedon the platform 22 'of the cage 21 and at the other end is connected and controlled byfthe solenoidco rod 38 operated by-the solenoids 39 and which is connected to a suitable signal systern.

The semaphore 40 at the top of the casing The means for operating the rocker arms are of course not confined :to the solenoid arrangement but may be accomplished mecording to the requirements v o In the operation of the invention when a train approaches a level crossing it closes a circuit'included in a signal system which is connected to the solenoids or other means released by the weight is lifted upwardly by 109" The gate iis formed a plurality of piv-l;

the other rocker arm having the counterbalance Weight. The actuating member secured the cage is also raised thereby sending the lazy tong bars to their extended position and forming a barrier across the road until the train has passed and immediately thereafter the lower rocker arm is released and the Weight it carries forces the cage back to its normal position and lowers the actuating member and which closes the gate.

What I claim"is-: I

1. In alevel gate a collapsible bar gate and operating means comprising a balance arm having suspended Weights from one end and an operating Weighted'bar pivot-ally'secured to the other'end and to the gate and a rocker arm having the Weights ofsaid operatingbar attached to one end for relieving the Weight on said bar and a motive power attached to the other end.

2. In a level crossing gate a collapsible bar gate and] operating means comprising. a balance arm havinga pivotally suspended Weight at one end and a link connecting the other end of said arm With a cage fixedly secured to agate post slidably secured insuitable bearlngs, a counter Weight resting on said. post in said cage, a rockerarm adapted to liftoff said counter Weight fromsaid postv a, and a motive power at the other end of said rocker arm.

3. In a level crossing gate a collapsible gate andoperatingmeans comprising a balance arm carrying an operating suspended 1 Weight at one end, a l nk p votal' ly secured to the other end, a cage for carrying a,

Weight counter balancing the aforesaid Weight and 11111:, an operating post secured to sa d cage, a rocker arm pivotally secured to said cage weight and, adapted to lift it: independently off said cage to release the balance arm Weight and actuate said. post and a solenoid suitably energized and, at,- tached to the other end of said rocker.
