RAILWAY cA'rn AND SIGNAL.

Application filed May 27,

' matically changed when the gate'is either opened or closed.

It is further required that when a train from the junior road is crossing the tracks of the senior road that the gate shall be locked across the tracks of the senior road. i The law further specifies that suitable signals be provided to indicate the position of the gate, which said signals usually consist of different colored lights tor use when the visibility is low and at night, and certain types or painted boards for use during the daylight.

It frequently happens that the flagman who opens the gate neglects to change the signals at the same time, with the result that serious accidents have occurred.

In order to prevent such-occurrences, I have devised a simple and effective means by which the signals automatically change with the opening and closing or the gate, so that it is impossible for the gate to be opened without the proper signal showing at the proper place.

Other objects and advantages of my invention will be disclosed in the. following specification, claim and drawings, in which Fig. 1 illustrates the application of my combined railway gate andsignal, showing the gate locked open for tree passage of a train on the main line; and, also, shows the vertically disposed arms of the signal'indi- V eating a clear track in both directions.

Fig. 2 shows that the track illustrated in Fig. 1 is closed and both the vertically disposed signal arms and the horizontal signals indicate that the track is closed.

Fig. 3 is a detailed view of the automatic locking device.

Fig. 4 shows in detail the manner in which the locking device may be secured by padlock.

Fig. 5 illustrates the manner in which the rotatable signal is hinged and supported against downward movement by a shoe.

My invention consists of a standard 1,

hingedly connected to a vertically disposed post 2, firmly set in the ground at the apex 1928. Serial 170. 112,013.

of the angle formed by two railways crossing each other; Rigidly attached at right angles to the standard lis a gate or signal on the opposite side of the railroad tracks from the post 2, shorter posts 1 and 5 are firmly set in the ground, thus it is obvious that when the tracks cross at rightangles the posts 4 and 5 will be disposed 90 deg. apart,

and the post 2 will be 111 the circle of the circle which would be inscribed by the rota- 4 7 tion of the gate or bar 3. 1

As the gate must be normally locked across the junior road, the post 4 is provided with suitable locking mechanism, shown in detwo other opposite sides show a different color light.

The standard 1 is, also, provided at its upper end with four signal arms, two of which 7 and 8 are permanently disposed in a horizontal position, the other two 9 and 10 being permanently disposed in a. vertical position. The horizontal arms 7 and 8 are painted with the usual signal colors, in such a mannor that they will always indicate whether the road is clear or closed by reason of the fact that the horizontal bar 3 and the standard 1 are rigidly hinged, as shown in Fig. 5, and when the bar 3 is moved from post 4 to post 5, or reversed, the signal will auto matically be moved or reversed.

An automatic locking device 11 is pivotally joined to the post 5 at 12, so that the locking portion 13 of the device normally rests on top of the post 5 by means of its weight. Its outer end is curvilinear in outline and of such shape that when the-bar 3 is swung against it the latch 13 is raised, permitting the bar to be held by the hooked portion 145. Rigidly attached to the top of the post 4 is a locking device, so designed that when the bar 3 is swung against it, it automatically closes the latch 15, one end of which engages a slotted portion, not shown,

' in the upright standardld.

An eye 17 is provided in the upper portion of the latch 15 through which the hook position across the junior tracks.

The'standard 1 is pivotally hinged to the post 2 by means of latches '19 and 20. A metal shoe 21 is provided with a suitable opening on its upper surface to receive the toe of the standard 1, thereby preventing the weight of thegateand standard from causing the hinges to sag or become unduly worn. Having fully described my invention and its method of operation and construction, whatI claim as new and useful, and desire to secure by Letters Patent is A combined railway gate and signal of the class described, comprising a vertical, rotatable standard hingedly supported by a post embedded in the ground in a vertical position adjacent a railroad track and adapted to rotate through 90 degrees, a,plurality of signal arms rigidly attached to the upper .end of said rotatable standard, two of which are diametrically opposite each other in a 35 horizontal plane, and two others being disposed in a vertical plane 90 degrees from the fixed my signature horizontally disposed signal arms, a signal lantern attached to the center of the upper end of said rotatable standard and having four plain sidesftwo opposite sides of which are enclosed with glass of one color and the "two alternate and opposite sides being enclosed by glass of a different color, -means for internally illuminating said lantern, a

horizon-tally disposed bar or gate rigidly attances from said rotatable standard,automatic locks rigidly aflixed to said posts adapted to engage and lock said bar or gate when swung with force against said locks,

means for securely locking one of said locks against accidental or intentional release by the use of an ordinary padlock, means for supporting the weight of said standard and said gate against vertical movement. p

In witness whereotI have hereunto af- EDNA J. CABLE.
