TELEGRAPH RELAY.
Application filed November 10, 1923.
To all whom it may concern:
Be it nnown that l, Gnoncn L. Rrwnon,
a citizen of the United States, and resident of Lakewood, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Telegraph Relays, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The objects of the invention are to provide means for simplifying the construction of a relay, containing main and holding magnets, and particularly relates to modified form of construction of the pole pieces of the holding magnet peri'itting them to come into close proximity to the armature lever without materially changing the weight of the armature and without increasing itslength or reatly modifying its shape.
To accomplish this result the holdingmagnet is placed on one of its longitudinal edges by the side of the main magnet, anl the pole pieces are extended laterally around one of the sides of the main magnet in such a manner that they are opposed to each other, and to the armature lever at a point central of said lever, so as to become officient in action.
In this manner the structure of the relay remains unchanged and the entire arrangement and assembly of the various parts is convenient and compact in shape.
The invention is hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the claims.
In the accompanying drawings Fig. 1 is a transverse section of the device on line 1-1, of Fig. 2, Fig. 2 is a plan thereof, Fig. 3 is a side elevation thereof, Fig. 1 is a perspective of the armature lever.
In these views .1 is the base on which the parts are assembled. 2 the main electremagnet. 3 is the. holding electromagnet which is placed vertically on edge closely adjacent to one edge of the main magnet thus melting a compact structure. -1 is the soft iron armature lover of the ordinary length which vibrates against the tension of a spring 5 between the front and rear elec trical contacts 6 and 7 respectively. 8, 8 are the pole pieces of the main magnet which when the main electric current energizes the main magnet attract the lateral wings or Serial No. 673,912.
side pieces 9 extending laterally from each side of the armature.
10, 10 are pivotal supports for the armature, positioned upon standards 11, 11 on the base. 12, 12 are the pole pieces of the holdin magnet which are laterally extended so as to encircle one side of the main magnet and are near together at the axial center of the main magnet so as to attract the armature when the local electric current is passed through the holdingmagnet. 13, 1e are posts through which the threaded supporting rods for the magnets are respectively passed, and in which they may be independently adjusted by means of nuts 15, 15, and 16 to regulate the gaps between their respective poles, and the armature. The front and rear contacts 6 and 7 are screw threaded and adjustable by means of nuts 7 6, 6, and 7, '4'" in posts 17 and 18.
In operation when the main current is passed through the main magnet thereby energizing the same, the armature lever will be drawn against the tension of the springs to contact with its front contact point 6. Also if an electric current is caused to flow through the holding magnet and afterwards the electric current is broken or cut off from the main magnet, the armature lever will remain on the front contact 6, or in the same position, by the effect of the holding magnet. Vice versa, if an electric current is caused to flow through the holding magnet thereby magnetizing the same the arma- W ture lever will be drawn to its front contact and if an electric current is caused to flow through the main magnet, and the current is afterwards broken or cut out from the holding n'iagnet the arn'iature lever will 9 remain upon the front contact, or in the same position by the attraction of the main magnet.
Having described the invention what I claim as new and desire to secure by l'iet" ters Patent is:
1. ln a relay, the combination with a main elcctro-i -agnet and pole pieces, and a holding electreunagnet of a support therefor, a vibratable armature lever common to both magnets, and pivotal support therefor at. one end thereof, and front and rear contact points tl'ierefor, and laterally *xtending pole pieces for said holding magnet the free extremities, said pole pieces being opposed to said common armature lever, said main electro-magnet being positioned horizontally on said base, and said holding clectr0- magnet being supported upon one longitudinal edge adjacent one side of said main electro-magnet, the pole pieces of said holding electro-magnet encircling said adjacent side of said main electro-magnet.
2. In a relay, the combination with a main electro-magnet and pole pieces and a holding electro-magnet of a support there-- for, a vibratable armature lever common to both magnets and pivotal support therefor at one end thereof, and front and rear contact points therefor, and laterally extending pole pieces for said holding magnet, the free extremities of said pole pieces being opposed to said common armature lever, said main electro-inagnet being positioned horizontally on said base and said holding electro-magnet being supported upon one longitudinal edge adjacent to With one side of said main electro-magnet, the pole pieces of said holding electro-magnet encircling said adjacent side of said main electroma gnet, said armature being provided With lateral extensions opposed to the poles of said main electro-magnet, the central portion thereof being opposed to the poles of said holding electroanagnet.
In testimony whereof, I hereunto set my hand this 1st day. of November 1923.
GEORGE L. RAWDON.
