Description
Patented Mar. 22, 1932 NETED STATES PATENT GFFQIQLE FRANK BOSH, OF LA GRANGE, ILLINOIS, ASSIGNOR TO KELLOGG SWITCHBQARD-AND SUPPLY COMPANY, 0F CHICAGO, ILLINOIS, A CORBORATON OF ILLINOIS RELAY Application led August 23, 1929. Serialro. 387,907.
My invention relates to electromagnets or driving tor use in electrical circuits, and as shown has to do more particularly with relays such as used in telephone circuits, although electromagnets of this type are also applicable for other uses.
In relays of the present type as commercially used, diculties are experienced in positioning the armature at the proper distance from the iron core, so that interaction between these two may take place to the best possible advantage.
To overcome this difficulty I have ar ranged a simple7 but elicient device permitting a ready adjustment of the width of the gap between the armature and the iron core through the instrumenta ity or" au externally and internally threaded portion of the iron core, and a nut and a screw engaging therewith. rllie screw maintains the iron core at the desired distance from the iron heel upon which the armature is ulcrumed.
A further object of my invention is to provide` the driving magnet of my device with adjusting meansI individual thereto and so arranged that said magnet may be adjusted towards or away from its supporting member.
For a better understanding of my invention reference may be had to the accompanying drawings, in which I have illustrated a preferred embodiment of my invention and in which like reference characters in the several views denote like parts7 and in which Fig. 1 is a plan view of the relay of my invention;
Fig. 2 is essentially the same as Fig. 1 but with the component parts disassembled in their respective order; and
Fig. 5 is a sectional view through the iron core.
Referring now more in detail to my invention as illustrated, the relay comprises an energizing winding 2 wound upon a suitable core 3 which core 3 is provided ith a screwthreaded extension 4 and a tapped hole 5. The core 3 and the winding 2 are suitably held in place or secured upon the angular extension 6 of the iron heel 7 by means of the screw 8 passing through a suitable opening in the angular extension 6 o the heel 7;and enga-ging the tapped hole 5 ot core 3.
The armature 9 isi'ulcrumedupon the iron heel 7 by means of the lugs 10 forming an integral part of the heel 7 and passing through .j suitable orifices in the armature 9. Tliesaid orifices are not shown in the drawings. The armature 9 is held in its normal position by the spring 11 secured to the heel 7 yby means of suitable screws not shown in the drawings. `The spring contacts 12 are secured to the iron heel 7 byineans of the screws 13fso .asto be properly acted upon by the attracted armakture 9.
For the purpose of regulating-the gap ,he-
Inut 14 turned to move the armature and heel,
as a unit, towards or away from the core. W hen this adjustment is made the screwV 8 is tightened'to secure the heel in adjusted position.
'While Iihave shown my invention as applied to an ordinary telephone relay, it is ap- .Y
parent that it Ends great utility when adapt ed to driving magnets of motor mechanisms, such as step by step mechanisms. Therefore, I aim to cover changes and modifications as come within the spirit and scope of the appended claims.
Having described my invention, what I claim as new and desire to secure by United States Letters Patent is:
1. A relay structure of the class described including a heel iron, an armature supported by the said heel iron, and an electromagnet adjustably secured upon the heel iron by means of a nut screw-threaded on the core of said electromagnet between said heel iron;
Hmmm.
and the coil of said electromagnet and a screw in threaded engagement with an axial orifice in said core.
V2. A relay structure of the class described including a heel iron, one or" the arms of the said heel iron extending longitudinally along an electromagnet and having an armature supported thereby7 the core of said electro. magnet being threaded externally and internally, said electromagnet secured adjustably to the said heel iron by means of an adjusting nut in threaded engagement with said external threads and between said heel ironand said electromagnet, and a locking screw in threaded engagement with said internal threads.
3. relay structure of the character described including a heel iron and an armature supported thereby, an electromagnet supported by said heel iron byY means of an externally and internally screw-threaded extension in the iron core, an adjusting nut between said heel iron and said electromagnet and engaging with the external thread of said extension, and a locking screw engaging with the internally tapped axial hole in said extension.
4. An electromagnet structure including a supporting member7 an electromagnet, an armature actuated by said electromagnet7 a core for said electromagnet, means having screw-threaded engagement with said core between the said supporting member and the said electromagnet for adjusting the electromagnetrelative to said supporting member7 and means for securing the electromagnet to said supporting member.
5. A structure including v a supporting member, an electromagnet, an armature 0perated by said electro-magnet, an adjustable member secured to said electromagnet between the said supporting member and the said elect-romagnet winding for adjusting the electromagnet relative to said supporting member andV means for securing the electromagnet to said supporting member.
Signed by me, at Chicago7 in the county of Cook and State of Illinois, this 21st day of August, 1929.
