POLARIZED RELAY FOR QUADRUPLEX TELEGRAPHS.
SPECIFICATION forming part of Letters Patent No. 275,185, dated April 3, 1883.
Application filed January 3, 1853.
To all whom it may concern:
Be it known that I, GEORGE W. UARDA- NIER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Polarized Relays for QuadrupleX-Telegraph Systems; andIdohereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.
The invention relates to an improvement in polarized relays for quadruplex-telegraph systems; and it consists in a polarized relay provided with three armatures and adapted to operate substantially in the manner hereinafter described.
Referring to the accompanying drawing, which illustrates a plan view of my invention, A denotes thepermanent magnet, B the electromagnet, and O D E the armatures, the two latter being provided with retractile springs a b. The magnets A B are of usual construetion, and around the latter the wire d is wound in the customary manner. The armature 0 passes between the ends of the electro-magnet B, and is acted upon by the current in said ends, being attracted in one direction by a negative current and in the opposite direction by a positive current. The armatures D E extend from their bearings to suitable points in front of the ends ot'the electro-magnet B, and, as aforesaid, are supplied with the retractile springs a b. The armatures D E are secured in such relation to the ends of the electro-magnet B as to render them susceptible to the influenee ofthe current passing through the electro-magnet when said current is of suflicient strength to overcome the force of the retractile springs a b. The armature G is without a retractile spring, and will be afi'ected bya weak current in the electro-magnet, as well as by a strong current, whereas the armatures D E will only be influenced by a strong current. It will be observed, therefore, that a weak current will attract the armature O and that a strong current will influence both the armature (J and one of the two armatures D E, according as the current is either positive or negative, the armature D responding to an increased negative current and the armature E to an increased positive current, or vice versa.
(No model.)
Q When a strong or an increased negative current is passing through the relay the armature O and the armature D will both be attracted toward the end 0 of the elcctro-niagnet, and when a strong or an increased positive current is in the electro-iuagnet the armature U and the armature IE will be attracted by the endf. A weak current, however, or one of only suffi cient strength to vibrate the armature G, will permit thearmatures l) E to remain unaffected, while a current of increased strength will infiuence not only the armature C, but one of the armatures D E also.
The tree extremity of the armature O is provided on opposite sides with the working-con tact m and resting-stop n, and from the working-contact m a wire, 1), passes to the electromagnettof the sounder F. From the pivoted end of the armature O a wire, a, passes to the local battery to, and thence to the electromagnet t, as indicated in the drawing.
The vibrating end of the armature D is be tween the working-contact .r and resting-stop y, and the like end of the armature E is between the working-eontact 1 and restingstop 2. The working-contacts l and mare connected by the wire 3. From the pivoted ends of the armaturcs D E wires at and 5 pass to the electro-magnet 6 of the sounder 7, the wire 4 being in circuit with the local battery 8.
The operation of the invention is as follows: The main-line current, it will be understood, is passing through the wire (I, with which the electro-maguet B is wound, and the object is to actuate the sonnders F and 7 through the local wires from the single relay under the various conditions ofthe current passing through the wire (I. For example, when a weak negative current is passing through the wire (I the armature U will be drawn against the workingcontact m, which completes the circuit through the armature, wires 1) a, battery to, and electro-magnet t, and has the efl'ect of closing the sounder F. A weak positive current in the wire (1 draws the armature 0 against the resting-contact n, breaking the circuit at m, and permitting the retractile spring 9 to open the sounder F. The weak negative, or the weak positive currentabovc mentioned beinginsufiieient to overcome the tension of the retractile springs a or Z), the armatures D and E are al lowed to remain against the working-contacts l and w, and when they are in this condition, which is that illustrated in the drawing, the sounder 7 will be closed, a complete circuit being formed through the said armatures, the wires 3 4 5, local battery 8, and electro-magnet 6. In case the current through the wire (I is made an increased negative, the armature C will be drawn against the working-contact m, coinpletingthe circuitof and closing the sounder F, and at the same time, the strength of the spring (6 being now overcome, the armature D will be moved from the working-contact or and against the resting-contact y, breaking the circuit of the sounder 7 at and permitting the spring-10 to open the said sounder. Upon the reversal ofthe polarity of the current last above described-4 0., from an increased negative to an increased positive current-the effect is to open the sounder F bybreaking its circuit at m,
' and to break the contact of the armature E at 1,
allowing the spring a to replace the armature D against its working'contact x and leaving the sounder 7 still open. In changing the increased positive to an increased negative current again, the sounder F is closed, the armature I) is brought against the resting-stop 3 and the armatnreE is drawn against the working-contact 1 by the spring I). In altering the polarity of the current, it from a negative to a positive, for instance, the contact of the armature E at 1 will be broken bei'ore the contact of the armature D at w is made, and it the current is changed from a positive to a negative the contact of the armature D atoo will be broken before the contact of the armature. E atlis made; hencein either case the sounder 7 remains open and undisturbed.
From the foregoing it will appear plain that a weal; negative current will close the sounder F and not afiect the then closed sounder 7; that an increased negative current will close the sounder F and open the sounder'i; that a ,rss
the term increased current I mean one of greater power than that exerted on the said armatures by the springs to I).
What I claim as myiuvention, and desire to secure by Letters Patent, is
1. The polarized relay herein described, consisting of the permanent magnet, electro-magnet, and the three armatures, the whole being arranged and adapted to operate substantially as set forth.
2. The polarized relay herein described, consisting of the permanent magnet A, electromagnet B, and armatures O D E, the two latter being supplied with the retractile springs (t I), substantially as set forth.
3. The polarized relay supplied with the armatures O, D, and E, in combination with the sounders I. and T, the wires p u, and local battery w, for closing the sounder F when the armature O is against its working-contact, and the wires 3 4: 5 and local battery 8, for closing the sounder 7 when the armatures D and E are against their working-contacts, substantially as set forth.
In testimony whereof I at'tix my signature in presence of two witnesses.
GEORGE \V. UARDANIER.
