4 Claims.
My invention relates to electric relays. The principal object is to provide a. slow acting relay of high efliciency to be operated by alternating or pulsating current. It is particularly suitable for relaying signals transmitted over telephone lines by the conventional magneto.
In describing my invention reference is made to the accompanying drawing. The figure shows other switch member and carries the contact point 1, in position to be contacted by point 5, when the lever I is depressed. The drum 8 with its attached wheel 9 is freely rotatable upon the pivot I0, carried on the end of lever I, as shown. Wheel 9 is of such size and weight that it resists sudden rotary movement. The weight of drum 8 and wheel 9 is counterbalanced by the weight I I. The armature I2 is supported in the field. of
magnet I3 by the leaf spring I4 so that it will vibrate, like the armature of a buzzer, whenever the magnet I3 is intermittently energized, as by alternating current. The armature I2 carries the arcuate member I5, freely oscillatable upon the pivot I6, eccentric to the arc of member I5,
which is lightly biased to the left by spring I1. When the drum 8 is in raised position the outer end of arcuate member I5 bears upon the nurled periphery of drum 8, as shown. Because the pivot I6 is on center the pull of spring I! causes the arcuate member I5 to exert some downward pressure upon drum 8, but this is slightly overbalanced by the upward pressure of leaf spring 4, so that the normal position of the elements is as shown in solid lines with the wheel 9 resting against the stop I8 and the switch points 5 and I open.
The operation of the relay shown in the figures is as follows: When magnet I3 is energized by alternating current armature i2 vibrates. downward movement of armature I2 is transmitted by the arcuate member I5 so as to urge both rotary and downward movement of drum 8 but because of the inertia of wheel 9 rotation is retarded, so that the downward movement of Each armature I 2 causes equal downward movement of drum 8 together with wheel 9 and end of its supporting lever I. In its downward motion lever I acquires some momentum and continues to move downward while the retraction of armature I2 raises the arcuate member I5 out of contact with drum 8 and it moves, responsive to spring I1, quickly to the left until it contacts drum 8 at a point farther along its arc and nearer to the sponsive to pressure of leaf spring 4, bears with motion of wheel 9 is arrested by the stop I8. Depression of lever I flexes spring 4 to close a local circuit from battery 24, over conductor 25, spring 6, points 5 and I, spring 4, conductor 26, through In addition to being slow acting and nonchattering this relay is much more eihcient than a conventional relay because it requires a smaller air gap between the armature and its magnet also because the efiect of the vibrations is cumulative to move the actuating element over a longer space thus permitting greater leverage for moving the switch member.
other circuit, rotation of the drum 8 will be sufficiently retarded by the mere inertia of wheel 9,
tion of the energizing current then other retarding means such as an eseapement, governor or the like may be added or substituted.
Another advantage of this relay is that the armature l2 may be harmonized to respond only to a current of a certain frequency to make the relay suitable for use on telephone lines using the harmonic system of selective ringing. It will be observed that the actuating lever l is responsive only to vibrations of the vibrating element viz. armature l2, with its arcuate member 15. The magnet i3 is shown here merely as one convenient means for causing the vibrations, obviously the same result would be achieved it the vibrations were caused by other means.
