Application filed February 5, 1906. Serial No. 299,416.
Be it known that I, EDWARD B. CRAFT, a citizen of the United States, residing at Chiive force acting on said armature by simply bending the tongue c and the adjustment may be made from the front of the relay by: 4
cago, in the county'of Cook and State of Illii inserting the nose of a pair of pliers through nois, have invented a certain new and useful the bridge b and bending the tongue 0.
Improvement in Adjusting Devices for Be lays, of which the following is a full, clear, concise, and exact description. f
My invention relates toan adjusting device especially adapted for use with relays, and has for its dbje'ct to provide an improved and simple device for varying or adjusting the tension upon a retractile spring of a relay armature or other device.
' I will describe my invention. particularly L by rel'erenceto the accompanying drawing, which illustrates the application of my invention to the armature of an electroinegnet, re serving for the appended claims a statement of the parts, improvements, and combinations which I consider novel with me.
' In the drawings, Figure l is a side elevation of a relay with a portion oi" its containing-case broken away, the armature being equipped with an adjusting device embodying my invention, and Fig. 2 is a detail pen spective View of the adjusting device.
The same letters of reference a e'used to designate like parts wherever they are shown.
T he armature a of the magnet a is pivoted. upon the pole-piece a oi the magnet andv is provided with the adjusting device of my invention. A U-shaped bridge-piece I) is socured to the under side of an extension o of said pole-piece and apliable tongue 0 is secured at one end to the yoke portion b oi said bridge-piece, the other end of said tongue being connected by a coiled retractile spring d ,with the armature a, said spring passing through an opening in the extension of.
spring may be adjusted to vary the retract- I claim l. The combination with a retractile -spri .ng, of a pliable tongue to which said whereby the tongue may be bent to vary the 6o retractive force oi. said spring.
3. The combination with an electro'rnag net, of an. armature therefor, a U-shaped bridge-piece, a pliable tongue secured atone end to the yoke portion of said bridge-piece, and a coiled retractile spring connecting said armature with the other end of said tongue.
4. The combination with an electromagnet, of an armature therefor, an extension from the polepiece of'said magnet; a U- [o shaped bridge-piece secured to the under side of said extension, a pliable tongue secured at one end to said. bridge-piece, and a coiled retractile spring connecting the other end of said tongue with said armature, said spring passing through an opening in said on tension.
in witness whereof I hereunto subscribe my name this 25th day of January, D.
