To all whom it may concern:

Be it known that I, DMrrRo HRYNIEWIQH, a citizen of the United States of America, residing at Livermore, in the county of lVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Railroad-Gates, of which the following is a specification.

This invention relates to certain new and useful improvements in railroad gates and has for its primary object to provide a railroad gate that is automatically operated to be moved to either open or closed position by devices positioned adjacent the track and operable by a train.

A further object of the invention has reference to a novel form o ftrip mechanism adapted for the operation of a railroad gate, the trip devices being arranged in opposed pairs and on different tracks to be simultaneously operated by the passage thereover of trains.

A still further object of the invention resides in the provision of a plurality of trip operating devices for an automatically opening and closing railroad gate so that a train engaging one of the devices will shift all of said devices and dispose the trip to be subsequently operated by the train in position for engagement by the train.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Fig. 10 is a cross sectional view taken on line XX 0f Fig. 8.

Briefly described, the present invention aims to provide an automatically operating railroad gate wherein the gate arms are shifted from their perpendicular to a closing horizontal position, and vice versa by the movement of the train over the track. Assuming that the cross gates are arranged at the outer sides of a pair of tracks, trip devices are mounted on the tracks in opposed pairs at relatively long distances at each side of the crossing gate, the opposed trip devices at each side being mounted on a shaft extending transversely of the two tracks so that the operation of onetrip will effect the operation of the trip on the other track. The connection between the trip devices and the crossing gates embodies a plurality of rope sections connectin the transversely positioned shafts to t e crossing gates while the crossing gates are independently connected by sets of ropes, and in a manner whereby the operation of one trip upon a track will set the other trip upon the same track for subsequent engagement by the train to eii'ect the reverse movement of the crossing gates. 7

It is not intended to limit the invention to the exact details .of construction herein disclosed as the present showin is only believed to be a preferable embodiment of the invention, the device as herein illustrated and diagrammatically shown in Fig. 1 embodying application to the separate tracks 1 and 2 having a crossing 3, a gate stand 4: being positioned adjacent the outer side of each track 1 and 2 and at opposite sides of the crossing 3 as clearly shown in Figs. 1 and 2 with gate arms 5 pivotally mounted in the upper ends of the stands. At each side ofthe crossing 3 and positioned a relatively long distance therefrom is .a transversely journaled shaft -6, the ends of which have a rope connection 7 with the gate stand 4.- while the gate standsare independently connected by the intermediate ropes 8, trip devices 9 being carried by the shaft 6 and each disposed between the rails of the separate tracks to be operated by a passing train to efiect the opening and closing movement of the gate arms 5 in a man ner to be hereinafter described in detail.

The gate stands 4 and arms 5 are shown more clearly in Figs. 3 to 7, there being provided a casing 10 inclosing a standard 11 having a bearing foot 12 at the lower end thereof by which the same is secured to the casing while the upper end of the standard 11 projects through an opening 13 in the casing and has pivoted 'as at 14 upon the upper end thereof the gate arm 5, the upper.

end of the standard 11 being bifurcated as at 11 as shown in Figs. 4 and 5 to accommodate the pivoting block 14 upon the lower end of the arm 5. The standards 11 are provided with sets of brackets and rope pulleys, over which pulleys the ropes 8 connecting the crossing arms at each side of the track are adapted to pass, and also the ropes 7 extending from the shafts 6 to the stands 4,'the standard 11 having a bracket 15 upon the outer face thereof as shown in Figs. 3 and 4 with three pulleys 16, 17 and 18'journaled therein. A bracket 19 projects from the outer face of the standard 11 adjacent the lower end of the bifurcated arms 11 and has journaled therein'a pulley 20 and two relatively smaller pulleys 21 and 22 respectively, said smaller pulleys being positioned upon the inner end of the bracket arm 19 and within the standard 11 as shown in Fig. 3. A stub shaft 23 extends between the side arms 11 of the bifurcated upper end of the standard and has four pulleys 24, 25, 26 and 27 journaled thereon, said pulleys 24 to 27 being positioned beneath the gate arm block 14'. The pulley and bracket construction at the opposite or inner side of the standard is shown more clearly in Fig. 5, the standard at the lower end thereof supporting a bracket 23 in which a pulley 29 is j ournaled while the upper end of the standard at the lower end'of the bifurcated portion carries a bracket 30 having a pulley 31 journaled therein, the pulley 31 alining with the pulley 27 upon the shaft 23.

It is believed that the invention will be better understood with the rope connections between the gate arms 5 at each side of the track as first described, attention being particularly directed to Figs. 3 to 7, a rope designated by the reference character a is secured at one end as at a to the outer side of the block 14 of one of the arms 5, the rope passing downwardly beneath the pulley 27, as shown in Figs. 3 and 4 over the pulley 31 in the bracket 30, downwardly under thepulley 29 in the bracket 28, and thence longitudinally of the track as shown in Figs. 1 and 3 for passing beneath the corresponding pulley 29 carried by the opposite standard 11, thence upwardly over the pulley 31, beneath the pulley 27 for attachment to the inner face of the arm head 14 as indicated at a. A second rope connection designated by the reference character 6 has one end attached as at b to the inner side of the block 14 of the arm 5, the rope 72 passing clownwardly beneath the pulley 24 and over the pulley 20 carried by the bracket arm 19, beneath the pulley 18 in the bracket 15., and through the opening 32 adjacent the lower end of the standard for longitudinal travel of the track and passage through a similar opening '32 in the opposed standard 11, thence upwardly from beneath the pulley 18 for passage over the pulley 2O and beneath the pulley 24 for attachment at its end as at 7) to the outer side of the mounting block 14. The rope connections a and 6 between the gate arms 5 cause the same to operate simultaneously, the operation of one arm being communicated to the other so that the same will be raised and lowered in unison.

Means is provided for shifting the gate arms 5 and includes the transversely journaled shafts 6 to which the trip devices 9 are fixed, each shaft 6 carrying a pulley 33 over which the rope 7 passes for communicating motion therefrom to the arms 5, the rope 7 being fixed to the pulley 33 and having the upper strand 0 at the righthand side as shown in Fig. 1 passed beneath the pulley 17 as shown in Figs. 4, 5, and 7, upwardly and! over the small pulley 22, beneath the pulley 25 upon the shaft 23 with the end thereof attached as at c to the outer side of the pivot block 14. The lower strand d of the rope 7 passing from the under side of the pulley 33 passes beneath the pulley 16 in the bracket, 15, thence upwardly and over the pulley 21, beneath the pulley 26 with the end thereof attached as at d to the inner side of the block 14. The operating rope 7 for the other arm 5 as shown in Fig. 3 has the upper strand 0 passed beneath the pulley 17, thence upwardly and over the pulley 22, under the pulley 25 and attached as at c to the outer side of the block 14, while the rope strand (Z passes beneath the pulley 16, thenceupwardly and over the pulley 21, beneath the pulley 26 for attachment as at d to the inner side of the block 14'.

The train operated trip mechanism for rotating the shafts 6 to operate the gate arms 5 is more clearly shown in Figs. 1 and 8 to 10, each trip device including a box like casing 34 positioned between the rails of the track and through which the shaft 6 is transversely journaled. A trip lever embodying upper and lower sections 35 and 36, has the lower section pivoted upon the transverse rod 37 in the casing 34 while a lever 38 having one end fixed to the shaft 6 has a link connection 39 with the brake joint 40 between the trip lever sections 35 and 36. The

upper section 35 of the trip lever projects through a slotted opening 41 in the upper end of the casing 34 and is normally retained in alinement with the lower section 36 by the coil spring 42 connecting the trip lever section 35' to the outer end of the lever 38. A trip device is positioned on each track and operatively engaged with the shaft 6, and the normal positions of the trip devices on the same track are the reverse, as shown by full lines in Fig. 8.

From the above detail description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that a train traveling in the direction indicated by the arrow 43 shown in Fig. 8 has the arm 44 carried there by depending from the train in position for engagement with the upper section 35 of the trip lever. Forward movement of the'trip device 44 will shift the lever sections 35 and 36 upon the pivot 37 to rotate the shaft 6 in an obvious manner, the motion of the shaft 6 being communicated by the rope 7 to the gate stand 4 and directly to the arms 5 by the connection 0 and d. The rope connections at and b, above described, between the opposite gate arms will effect simultaneous movement thereof while the operation of the distantly positioned trip device 9 is effected through the rope connections 7 with the gate arms 5. It will therefore be seen that the operation of one trip device 9 will effect movement of all of the trip devices as well as operating the gate arms 5. When the train has advanced to place the trip device 44 in the dotted line position shown in Fig. 8 the trip arm section 35 will move on its brake joint 40 with the section 36 and against the tension of the spring 42 to permit the trip member 44 to ride over the trip arm section 35, the spring restoring the arm section 35 to its normal position in alinement with the section 36 in the dotted line position shown in Fig. 8. Simultaneously with this movement, the distantly positioned trip lever on the same track is moved to the dotted line position and disposed for contact by the trip device 44 on the train. The reverse operation will be accomplished when the distantly positioned trip lever is engaged by the trip device 44 to restore the gate arms 5 to their open perpendicular positions. The operation of the several parts is positive in the movement thereof as the parts are connected by rope devices so that the movement of one part is simultaneously communicated to all of the parts. As shown in Figs. 3 to 5, a visual or audible signal may be placed in the sockets 5 in the gate arms 5 and be suitably timed for operation with the movement of the gates.

While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed. v

What is claimed as new is A railroad crossing gate comprising supporting standards, gate arms pivotally mounted in the u er ends thereof, a pair of rope connections between the lower ends of said arms with the opposite ends of each rope connected respectively to the inner and outer sides of the arms, guide pulleys sup ported on said standards over which the rope connections pass, train operated means arranged at each side of the gate having rope connections with the adjacent gate arms for operation thereof, the rope connections between the arms .eifecting simultaneous movement thereof, and guide pulleys supported on said standards for the ropes connecting the train operated means to the gate arms.

In testimony whereof I aifix my signature in presence of two witnesses.
