ISIDOR KITSEE, OF PHILADELPHIA, PENNSYLVANIA.
TELEGRAPHY.
Specification of Letters Patent.
Patented .April 2, 190'?.
Application filed August 27,1906. Serial No. 332.175.
To all whom/ t may concern:
Be it known that I, IsmoR Krrsnn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Telegraphy, of which the following is a 'specification.
My inventionrelates to an improvement in telegraphy, and has more special reference to the receiving device therefor.
On lines with great capacitywsuch, for
instance, as submarine cables-very delicate instruments have to be employed, and the particular condition of the cable results in the so-called Hmoving-of the Zero. More sp eci ally is this the case when the method of transmitting impulses with the aid of the siphon moves, say, to the right, and before this Siphon has assumed its normal or Zero position a second impulse of the same polarity drives the siphon farther up to the right, and for this reason the Siphon never comes at rest at the normal or Zero position till a very long pause is made between thea signals.
The object of myinvention is to overcome this difficulty and to bring the movable part of the receiving device to its normal or Zero position after each impulse received.
It is obvious that this my invention may be applied to the Siphon-recorder as used today or to any of the well-known electromagnetic devices.
In the drawing I have illustrated this my invention as applied to an electric coil provided with a movable lever.
The drawing represents in diagrammatic view part of a line, a receiving-coil inserted in the line, and my device attached thereto.
A A is the line of transmission; B, the receiving-coil; C, the movable lever of same; D D, contacting` points, here shown as cone nected to each other. To the contact-points and movable lever, respectively, is connected the local circuit, comprising the wires l and 2, the source of current l?, and the electromagnet E. This electromagnet is provided with the armature G, in proximity of which is the conducting-spring H. In shunt as to the receiving-coil B is the circuit comprising the wires 3 and 4, the wire 3 connected to the armature G and the wire 4 connected to the conducting-spring II. Normally-that is, when the movable part of the receiving device, here shown as the lever C,
is out of contact with the contacts D D-the local circuit embracing the electromagnet E is open. The armature G, therefore, will be drawn upward by its spring but as soon as the local circuit is established through the connection of the lever C with one ofthe stops D D then the electromagnet E is energized and the armature G is drawn downward toward its core. During this downward motion the armature encounters the spring I-I, is compelled to make contact with same, thereby closing the circuit comprising the shunt 3 and 4.
Where a polarized relay is employed as the receiving device, the lever of which always rests against one point till an impulse of the opposite polarity drives it to the opposite point, the contacting of the armature G with the spring I-I when this armature is drawn downward may have its advantages; but in some cases where a siphon-recorder is employed it is best that the upper surface of the spring shall be non-conducting and the connection of the shunt only be made after the armature has been drawn downward and. released by the opening of the local circuit. In other cases it may be advantageous to have this shunt established both ways-that is, through the downward stroke of the armature G as well as through the upper stroke of this armature. The main feature is always to short-circuit the coil after each impulse, no matter if this short circuit takes place through the downward stroke of the arma ture only or through the upward stroke, or through both.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. As a means to return the movable part of a receiving device inserted in a line-of transmission to its normal or Zero position, a shunt around said receiving device, said shunt embracing the armature of an electro- IOO IIO
magnet, a stationary contact in the region of said armature, said armature adapted to close said local circuit only during the return movement to its normal position.
2. In telegraphic apparatus, the combination With the relay or receiving` device inserted in the line of transmission of a shunt-circuit embracing the armature of an electromagnet and means to close said shunt only during the movement of said armature from one position to a second position.
3. In telegraphic apparatus, the combination With the relay or receiving device inserted in a line of transmission7 a shunt-circuit embracing the armature of an electromagnet and means to close said shunt during` the upward movement of said armature.
In testimony whereof I affix my signature in presence of two Witnesses,
