SIGNAL DEVICE.
Application filed February 25, 1927. Serial No. 170,897.
This invention has for its object the pro- One of the levers is short, that is, it does 55 vision of an automatic signal device for railnot project above the rails at any time While road crossings, so that the oncoming train the other one is long enough to project far will itself signal motorists and pedestrians enough above the rails to engage the cow f its pproach. catcher of a locomotive. The longer lever In the drawings: nearer the crossing. on Figure 1 shows a perspective view of the lVlthin the post the shaft 8 isconnected to device in Operation a lever arm 9 (Fig. 2) extending at right Fi 2 Shows a id l v ti f th d angles to same, which is in turn hinged to a w Vice link member 10, which is hinged to the Figure 3 shows a cross section taken on the warning arm 4:, which is trunnioned near its (l5 li 3 f Fig, 2, mner or shoulder end to the post.
Referring to Fig. 1,1 indicates a roadway, The operation of the device is as follows:
2-2, a railroad track crossing same, 3-3 a The coweatcher of the locomotive first 5 pair of posts n'iounted one on each side of strikes the lever 5 and pushes it forward,
th d d ontaining within themthereby exerting a pull on cable 6 and short selves signal arms 4; and the lever means evel 01' rocker 7, thereby turning shaft 8 d ted to raise the arms 1 m, rning poand pulling down associated lever 9 from iti O f th Posts i l indi at d within the post and pulling short end of arm i fhi 2 by numeral 3, andshows the arm a by means of link 10, thereby raising arm. i t d d gignalling position A hand As the train advances, the cowcatcher eni is carried on the end of the arm. A hugages the longer lever of rocker 7 pushing man face is preferably painted on the post shaft 8 in the opposite direction from the so as to give the whole the resemblance of a Operation just described and sets in motion J h 'b i ith an arm t nd d, the same operation of levers, but in reverse The means by which the arm is extended d ec ion. By making the cable 6 longer and retracted by the train are as follows: 5 is han any train operating over the road, sia h t lever i d on trunnions a d fasmultaneous operation of the two levers will tened to a base by same, said base being fast never occur. By providing one of these deto the ties of the track and located at a convices on each side of a crossing complete prosiderable distance along the track fro th tection is assured. The two devices should crossing. a be oppositely arranged.
The lever 5 has the general shape of a dia- I claim mend except that the corners are rounded In combination with a railway crossing, a
and the edges slightly bulged, providing a post, a warning arm therein, a link and lever (Wed mm Sin-face W'h no train i passalso contained therein for extending and re 9 ing this lever or cam is in upright position tracting said arm, a rocker shaft extending midway between the rails. The lower end across the track below the rails, a bell crank of the lever 5 weighted, has fastened to it, lever fixed to said rocker shaft and having by any suitable means the end of a cable 6, long and short arms, a cable fast to the short which extends between the rails of the track arm of the bell crank lever, a lever at a subalmost to the crossing, that is, to where a stant-ial distance away from the crossing, rocking member 7 is located. This rocking fulcrum'ed in its middle, and connected to member consists of a base located between the cable and normally disposed in a vertical the ties, and below the rails a shaft 8 carposition to be engaged by moving railway ried by the base and extending into the post trains whereby to place the cable under ten- 3. The shaft is rotatably mounted in the sion to rock the bell crank lever to a position bearings of the base. The shaft extends to dispose its long arm in a vertical posipreferably all the way across the distance tion and to actuate the rocker shaft to ex- 50 between the rails. Midway between the tend the warning arm, the long arm of the rails, a pair of levers are attached at right bell crank lever being subsequently engaged I angles to the shaft and at somewhat less by the train to reversely actuate the mechathan a right angle toeach other. Both are nism to retract the warning arm. attached to the shaft at its middle point. BRITTON HYBARGER.
