RAILWAY SIGNAL.

Witnesses Inventor r Attorneys which is supplied to the magnet 19, due to a break in the line or the like, will eflect a denergization ,of the magnet, the semaphore moving into a position indicating safety, although dangdrous conditions may still exist. However, at the same time that the magnet 19 is denergized, the magnet 45 will be denergized also. The ball armature 56 will thereupon be released by the electro-magnet 45, the ball armature rolling along the cylinder 43, and effecting a tilting of the cylinder 43 upon the pivotal mounting 44. This tilting of the cylinder 43 will cause that part of the electro-magnet 45 to which the numeral 58 is applied, to engage the lever 25, thus tilting the lever 25 in the same manner as though the electro-magnet 19 were still acting upon the armature 21. Therefore, when both of the magnets 19 and are deenergized, due to the cutting oflt' of the current to the magnets 19 and 45, the semaphore 36 will assume the danger position.
Without specific illustration, it will be understood that the circuits may be so arranged that the curi'ent supply into the windings 100 of the magnet 45 will continue, except when there is a break in the line, or a failure of current, from any other accidental cause, the magnet 19 exercising its usual function in throwing the semaphore 36. Therefore, the magnet 45 will \engage the lever 25 to throw the semaphore 36 only when there is a total loss of current, rendering the magnet 19 ineflicient to indicate the presence of danger.
Having thus described the invention, what is claimed is 1. In a device of the class described, a pivotally supported electromagnet; an armature having a common pivotal support with the magnet and responsive to the magnet to change the center of gravity of the pivoted parts and thus effect a tilting (of the magnet; a movable operating meinbcr adapted to be Engaged by the magnet whcn the same is tilted; and a signal controlled by the operating member.
I In a device of the class described, a pivotally supported electro-magnet; an aamature having a common pivotal support with the magnet, the armature being adapted to be attracted by the magnet when the latter is energized, the armature being movable when the electro-magnet is deenergized, to change the center of gravity of the pivoted parts and thus effect a tilting of the magnet; a movable operating mem ber adapted to be engaged by the magnet when the same is tilted; and a signal under the control of the o ierating member.
3. In a device of the class described, a pivotally supported casing including a support and an electro-magnet; a rolling armature Within the casing, responsive to the magnet, the rolling of the armature serving to change the center of gravity of the casing and parts supported thereby and thus tilt the casing; a movable operating member adapted to be engaged by the casing when the latter is tilted; and a signal connected with the operating member.
4. In a device of the class described, a pivotally mounted casing including a support and, an electro-magnet; a rolling armature within the support, responsive to the electro'magnet, the armature, when released from the magnet, serving to change the center of gravity of the casing and parts supported thereby and thus eiIect a tilting of the casing; and a signal with which the casing is operatively connected. 7
5. In a device of the class described, a movable operating member; an electro-magnet located upon one side of the operating member and adapted to move the same in one direction; another electro-magnet pivotally supported upon the other side of the operating member and adapted to serve as a stop therefor; an armature having a common pivotal support with thelast named Y magnet, the armature being movable when attracted by the last named magnet, and when released therefrom, to change the center of gravity of the pivoted parts, and thus to effect a tilting of the last named magnet in both instances, the operating member being engageable by the last named magnet, when the same is tilted due to a release of the armature, to .duplicate the movement in the operating member, produced by the energization of the first named magnet; and a signal with which the operating member is connected.
In testimony. that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
