TRAFFIC-SIGNALING DEVICE.

Application filed June 17, 1920.

/ Traffic-Signaling Devices, of which the following is a specification.

My invention is an lmprovement in trafiic signaling devices, and has for its object toprovide a device of the character specified especially adapted for use in mines for controlling the traffic at street intersections, wherein the signal is supported by overhead means, permitting the usual standard to be dispensed with, and wherein it may be operated from the street, so that it is not necessary to remove the signal when the rush hours are passed.

In the present embodiment of the invention, a suitable casing is provided comprising a body 1 of sheet metal forinstance, having in its opposite faces cut-outs 2, forming letters which form legends as for 1nstance Stop and Go. Sheets of glass or the like indicated at 3 are arranged on the inner faces of the side walls of the casing, the said sheets being white or frosted, and the sides of the box are suitably colored, as for instance red, at the legend Stop and green at the legend Go. These sheets rest on the casing bottom, and are held in place by clips 4 secured to the side walls.

The top of the casing at its center has an outlet nipple 5 for the heated gases, and a hood 6 is arranged above the outlet, the

hood being supported by a shaft 7 which passes axially of thecasing. This shaft 7 is hollow as shown, and there'is provided a sleeve 8 capable of turning and also sliding on the shaft at the opening through the bottom of the casing for the shaft, and this sleeve has a-flange 9 which is secured to the bottom by means-of bolts or the like, as shown.

' A second sleeve or: collar 10 is secured to the shaft near the top of the casing, and the said sleeve or collar carries a frame 11 which supports electric lighting sockets 12 for providing illumination within the easmg.

The sleeve '8 is movable vertically onthe shaft, and the lower end of the said sleeve has a series of notches 13 which are spaced apart from each other at angular intervals of 90. One wall of each notch is higher than the other, as clearly shown in Fig. 5, and an incline 14 leads from the low wall of each notch to the high wall of the succeeding notch.

These teeth and inclines are one section of a clutch, the other section being formed by a collar 15 whichis secured to the shaft 7, and which has teeth 16 for engaging the notches 13, and inclines 17 fitting the inclines 14. When the two sections of the clutch are in contact, the teeth are in engagement, withthe notches and the inclines 7 fit the inclines 14.

The underface of the flange 9 has a series of ribs 18, each of'which extends substantially radial with respect to the flange, and the said ribs are angular, each consisting of a portion which is radial to the shaft, and a portion which is inclined with respect thereto.

A lever 19 is pivoted to the shaft below the collar 15, and this lever normally occupies the inclined position shown in Fig. 2. The lever is pivoted intermediate its ends, and on the lower end of the lever there is mounted a counterweight 20 which is adjustably held on the lever by means of a set screw. 21, the set screw being threaded through a bearing which is slidable on the lever.

The other end of the lever is bent angularly as shown in Fig. 2, and has connected therewith a rod 22 which is provided at its lower end with a ring as shown, for en gagement by a hook on the end of a staif 23, which may be grasped by the traffic officer as shown in Fig. 1 and engaged with the ring to operate the lever.

The lever has a lateral lug 241 at its pivotal connection, the said lug extending upward, and to this lug is pivoted a pawl arm or lever 25. The said lever is forked at one end, and a roller 26 is journaled between the arms of the fork, the said roller being adapted to engage flange 9 and then the ribs 18' on the flange 9. The other end of the lever is counterweight-ed as shown, and referring to Fig. 6, it will be seen that the lever is angular, the portion bearing the roller extending at an obtuse angle to the portion carrying the counterweight.

When the lever is swung by means of the staff 23, the arm or lever 25 will be swung upwardly, and the roller 26 will engage the flange 9. F urther swinging of the lever will cause the end of the pawl armhaving the counterweight, to engage the lever 19, and continued movement of the lever 19 will zliftthe casing 1 upwardly on the shaft 7. I

As the lever is swung still farther, the casing being now released from the shaft through the lifting of the same, will be moved angularly, to move one set of legends from display position, and to move the other set into display position. The shaft 7 may be suspended in any suitable manner, as for instance by trolley wires as shown in Figs. 1 and 2.

.lVith this arrangement a cross is connected with the top of the shaft 7, the arms 27 of the cross having at their outer 'ends means indicated at 28 and of any desired construction for connecting them to the trolley wires, indicated at 29, and these connecting means 28 are insulated from the cross arms. Thus the shaft .7 is supported at the street intersection at the center of the rectangle formed by the crossing wires.

The signal may be'operated from a distance if desired. With this arrangement, the signal indicated generally at 30, and which corresponds in all respects to the construction shown in Figs. 1 and 2, and is similarly supported, is operated by a flexible member 31. This flexible member passes from the lever downwardly beneath the pulley 32 supported by a bracket 33 at the lower end of the hollow shaft. The flexible member then passes upwardly through the hollow shaft, and over a pulley 34supported by one of the arms of the cross 35 to the place from which it is desired to operate the signal, being guided and directed by the pulleys if desired.

The pulley 34 is journaled'in the bracket 35 which is supported by one of the arms of the cross. Referring to Fig. 1 it will be seen'that the bottom of the casing 1 is of openwork construction to provide for a free circulation of air which enters through the open work bottom and passes, out through the nipple 5. The cone-shaped shield 6 prevents the entrance of water to the casing. The open work construction also permits the light to be reflected downward onto the tra fic officer operating the device, where the same is operated from a position below the signaling device. Preferably the inside of the casing is painted or enameled in white to intensify its reflecting action.

In operation, the device maybe arranged as shown in Fig. 1, to be operated from directly beneath, or it may be arranged as shown in Fig. 10, to be operated at a distance; In the first case, the traffic officer will engage the staff with the ring on the element 22." When he desires to change the direction of movement of the traffic, he will pull downon the staff, which will swing the lever 19, lifting the casing, and giving the same a quarter turn. This movement will place the Stop and Go signs at right angles to the position they formerly occupied.

The teeth 16 and the notches 13 provide a positive lock for the casing when it has been turned a quarter turn. The interengagement of the teeth and notches also provides stopsfor limiting the movement of the parts. In Fig. 8 is shown the bolt which connects the lever 19 to the shaft. This bolt 36 has a plane portion 37 adjacent to the head on which the lever swings. In Fig. 9 is shown one of the ribs 18. This rib as shown, has a threaded stem 33 which engages the flange, and it has an opening 39 at the opposite end for receiving a rivet or the like to connect the said end.
