have invented or, discovered new and useful Improvements in Telegraph-Relays,
which the following is a specification.
My invention relates to relays for telegraph circuits, and it has for its object to provide a relay which shall be simpleand compact in construction and effective and durable in service. I
Relays, as usually constructed, are of the horseshoe type and consist of two parallel spools of wire wound on two soft iron cores connected by a bar of ironknown as a yoke. Such spools are so wound that the free ends of the cores are oppositely magnetized, one i being a north pole and the other a south pole. In relays for telegraphy it is desirable that the armature be able to respond correctly to the most rapid and varied action to which the line may be subjected, andto do this irrespective of the atmospheric conditions. That relay is best which will -most quickly attract its armature after the circuit is closed and most quickly release the same when the circuit is opened.- The magnets of the re-,
lay must, therefore, be. so constructed as to attract the armatureas qulckly'as possible and to also releascit as quickly as possible.
The core of a magnet having a closed or nearly closed -1nagnetic circuit retains a small amount of residual magnetism for some time after the energizing'circuit has been broken, and, since the ideal electro magnet for telegraph work is one which will discharge all its magnetism with the. cessation of the current and W111 attract the armature quickly, when energlzcd, I have devised a relay provided with two oppositely wound] magnet coilsso disposed that the adjacent v poles of the same sign will act simultaneouslyv and equally upon an armature, and thus exert a strong and quick pull. In order to insure a certain and prompt release of the armature when the circuit of the magnets 1s opened, I provide no external magnetic c1rcuit and, consequently, there is substantially no residual magnetism to impose a drag upon the armature.
- With my invention, the armature is able to respond at all rates of telegraph transmission, whether the currentbe strong orweak, and without continual adjustments of the tension of the armature spring or the distance'between the armature and the pole pieces of the magnets. By means of my inlongitudinal section of the magnet; Fig. 5"
an elovation of the supporting connection for the magnet; Fig, 6 a side and an end View of one of the cores and pole pieces of the magnet, and Fig. '4' a diagram of a modification of my invention, the magnets being.
shown series wound.
Referring now to Figs. 1 to. 6, each magnet has a central support 1, composed preferably of insulating fiber. This support has a central portion. 2, of a larger-diameter than its end portions 3. Sleeved on the end portions 3 are tubular soft iron"'cores 4:, which have their inner ends expanded to fit the enlargedportion 2 of the support 1. The adj acent ends "of the cores do not entirely touch each other, but are separated by the narrow air space or gap 5. -0n the reduced portions of the cores are the windings 6 and Twound in ppposite directions, 'as shown in Fig. 3.
The inner ends of the-windings are shown connected to the line wire 10 by means of the wires 8 and9 and the outer ends to ground 11 by the wires 12 and. 13. The wires 8 and 9 are connected'to the binding post 14:, and the wires 12 and 13 to the binding post 15. As the incoming current passes right and left and in opposite directiens, adjacent pole pieces of the magnet will have the same polarity and will act upon the armature inde pendently and simultaneously. Since the walls of the tubular cores and pole pieces are thin, a small amount of iron is utilized to conduct the magnetic flux and, at the same time, cores of convenient size for the coils are provided. The magnets are supported by a bracket 16 by means of a stem 17 which is screwed into a hole 18 in the support 1 and is provided with a fiber washer 19 to engage the pole pieces. A coil-spring 20 is placed on the stem 17 between the magnet and the bracket 16 and a nut 21 on the stem may be utilized to adjust the magnet relatively to the armature 22. A. bracket 23 supports a back-stop 245 having a non-conducting front end and also a front contact stop 25 for the armature 29. which is normally held against the back-stop by a spring 26, the outer end of'which is'connected to a rotary thumb shaft 27, bywhich the tension of the spring maybe adjusted. The shaft 27 is mounted in a T-rod 28 which is adjustably mounted in a post 29. The bracket 23 is connected by a wire 30 to a binding post- 31, and the armature 22 is connected by a wire 32 to a binding post 33. The front and back stops are. in the form of screws, whereby they may be adjusted. The binding posts 31 and 33 are in series witha sounder mag-- net 34 and a battery 35. The armature 36 of the sounder is retracted by a spring 37 and may be used as an element of aTepeater, ifdesired.
The wiring shown on the drawings is merely illustrative of one way of connecting up the apparatus, but it may be variedto suit the ideas of different persons. In Fig. 3, I have shown the windings of the magnet connected in multiple, but they may be connected in series, if preferred, as shown in Fig. 7. I
I have shown my magnets with their cores in alinemeut. which is the arrangement I prefer. though I would not be limited thereto in claims which do not specify the same.
Where magnets have their cores parallel,'
they usually have a Tshaped armature the head of which is broad enough to cover both cores, thus necessitating a larger or heavier armature than can have its inertia overcome by weak currents. It is an advantage to' vention to cores of any specified form or dimensions or, in fact, to the employment of magnetizable cores of any kind, though the operation of the relay will probably be found more satisfactory if the coils are provided with some magnetizable material to conduct-the magnetic flux to the armature.
I do not desire to be limited to the precise construction shown and described but claim protection on all fair equivalents.
