. RAILWAY-CROSSING GATE.

Application filed April 14, 1925. Serial No. 23,081.

provision of a railway crossing gate which 6 will be automatically moved into an opera tive position by an approaching train and held in such position by the train while passing the crossing; the gate being properly weighted to cause it to return to its inopera- 19 tive position after the train has passed.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawingforming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 7 is a fragmentary transverse sectional view taken upon line VIIVII of Fig. 2,

Figure 8 is a detail longitudinal sectional view taken upon line VIIIVIII of Fig. 2, and

Figure 9 is a modified form of connecting mechanism by means of which the gate arms arranged onthe opposite sides of the track may be actuated simultaneously.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the railway track which is crossed at 6 ,by a road, or the like. Arranged on opposite sides of the track 5 at the roadway 6 are the posts 7, each of which has a gate arm 8 pivoted thereto and weighted at 9 for causing the arms to normally be arranged in their inoperative positions. v p

The posts 7 have rotatably mounted thereupon iallb gilfOpvd pulleys 10,11, 12 and 13, as indicated in the varidus fi ures. At dis randy spaced points along tlie track 5 are arranged the brackets let which support the grooved trated. t I.

In Fig. 1 the ends 19 of a cable A are illus trated as being connectedto the gate arms 8 on one side of the track illustrated. This cable extends from the ends 19 downwardly and underneath the pulleys and 11 to extend as at 20 and 21 to the pulleys 17 and r 15 respectively where the said cable passes over the pulleys just referred to and then back to and beneath the pulleys 10 and 11 to its united or unbroken portion beneath the pulleys 15, 16, 17 and 18, as illuscrossing 6, as indicated by the reference numerals 22 and 23, the cable at 23 passing beneath the pulley 11 and downwardly under the guide pulley 24 while the cable at 22 passes under the pulley 10; The portions 21 and 23 of the cable are fastened together at 25 in close proximity to the pulley 15.

In Fig. 4 the cable A is illustrated as being fastened at 26 and 27 to opposite sides of the pulley 15. This pulley 15is illustrated in Figs. 1 and 2'as having fastened thereon the normally vertically extending arm 28. In Fig. 5 this arm 28 is illustrated as having been engaged by a wiper member 29 carried by an approaching train, not illustrated, and. moved for causing thepulley 15 to be rotated to draw the cable, as illustrated. This drawing of one of the sides of the cable I will cause both of the cable parts 21 and 23 to be pulled upon, dueto the connection 25. This pulling uponboth ot' the cable parts 21 and 23 will cause the gate arms 8 to be moved into their operative or roadway closing positions.

It is to be understood that this arm 28 and pulley'15 are distantly removed from the gate arms 8, and, in View of this fact, after the last car carrying a wiper 29 has passed over the arm 28 and while the train would still be passing'the roadway 6, the gate arms 8 would be permitted to move into their inoperative or roadway opening positions. To overcome this undesirable condition, the shaft 30 carrying the pulley 15 has keyed thereto, see Figure 8, a grooved pulley 31 which has one end of a cable 32 fastened thereto. This cable extends to the grooved pulley'34 which is loosely mounted upon the shaft supporting the grooved pulley 11. thereupon a normally vertically extending arm 36. It will new be seen thatdue to the engagement of the arm as by the mesa as This grooved pulley 34 has mounted carried by the train cars, the pulley 15 will be retained in its operated position even after the train'wipers have passed over its arm 28.

In 3 the gate arms on the opposite side of the track are shown. These arms are connected to the ends 19 of a second cable B which extends downwardly to pass around the pulleys 12 and 13 and from them to the distantly removed pulleys 1G and 18 which the cable passes around and returns to and beneath the pulleys l2 and 13 to its united or unbroken portion beneath the crossing 6. The parts of the cable in close proximity to the pulley are connected together at 25 and are connected at 26 and 27 to opposite sides of the pulley 18. It will now be seen that by m'tating the pulley 18 by the arm 18 in either direction, cable portions will be pulled upon for moving the gate arms 8 into their roadway closing or operative positions in the same manner and for the same result as the above described arms 28 and 36 operate.

For the purpose of connecting the cables on too opposite sides of the track 5 for causing the actuation of one to actuate the other, the pulleys l7 and 18 have their supporting shafts provided with sprocket wheels 38 upon which ride the sprocket chains 39 which also travel over the sprocket wheels -10 mounted upon the opposite ends of the single shaft 11.

Fig. 9 is intended to illustrate the possibility of connecting the distantly removed pulleys 15 and 16 by similar sprocket wheels 38, sprocket chains 39, shaft s1", and sprocket wheels 40.

It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examplesof the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing "from the spirit of the invention or the scope of the subjoine'd claims. c

Having thus described the invention, 1 claim 1. In a device of the type de'- ribed, the combination with a railway tr :h, of a pair of s )aced posts on each side of said track, a gate arm pivoted to each post, a cable for each side of said track connected at its free ends to said gate arms, means for inovab y supporting the intermediate portions of said cables to permit the latter to extend to distant points along the track, and means adapted to be controlled by an approaching train for moving! said cables to cause the arms to be moved into their operative positions.

2. In adevicc of the type described, the

con'ibination with a railway track, of a pair of spaced posts on each side of said track, a gate arm pivoted to each post, a cable for each side of said tracl: connected at its free ends to said gate arms, means for movably supporting said cables to permit the latter to extend to distant points along both sides of; the track, means adapted to be controlled by an approaching train for moving; one off said cables to cause the arms con ected thereto to be moved into their o u;:-itive positions, and means for operatively connecting; the second cable to the cable actuated by the train.

3. In a device 01" the type described, the combination with a railway track, of; a pair of spaced posts on each side of said track, a gate arm oivoted to each post, a cable for each side of said track connected at its tree ends to said gate arms, means tor movably supporting said cables to permit the latter to extend to distant points along both sides of the track, means for connecting; together ditlerent portions of each cable so that movement of a cable will cause both of the free ends of the same to pull in the same direction upon the gate arms connected thereto for moving both gate arms into their operative positions, means adapted to be controlled ley an approaching train for moving said cables to cause the arms to be moved into their operative positions, means actuated by the train when passing the gate for causingthe arms to remain in their operative positions until the train has passed.

l. In a device of the type described, the combination with a railway track, of a pair of spaced posts on each side of said track, a gate arm pivoted to each post, a cable for each side of said track connected at its "free ends to said to arms, means for inovably supporting said cables to permit the latter to extend to distant points along both sides of the track, means to; connecting together difi 'erent portions (it each cable so that movement oi a cable will cause both of the free ends of the same to pull in the same direction upon the gate arms connected thereto for movi 5; both state arms into their operative positions, in ans adapted to be controlled by an approach ng; train tor moving one oi'f said cables to cause the arms connected thereto to be moved into their operative positions, means tor o 'icrativcly connecting the second cable to the cable aclu ated by the train, and means actuated by the train while passing the gate {or causing: the arms to remain operative until the train has passed.
