" Be it ,known thatfL RAY H. Manson, a I

Elyria, in the ountyof Lorain and State of Ohio?"hjaye-invented certain new and useful improvements in Relays, of which the following isi-a specification, reference being had This invention relates to relays, and more particularlyltolcut-out relays, and has for its objjeictto provide an improved relay for the turerto render the relay. insensitive to small f currentsWithut,interfering with the positive' action otthe'relay under the' influence of a 'local-circuit current, said relay also having Han armature-prov`idedwith an elongatedl angularly-disposed portion serving as a couni terwleight to produce a positive electrical conl overlying the armature without the interposition ofsplring action, the armature having a special forni of loose pivotal support at` the l by means oi which the relay is secured to the ofthe contact-strip cut away.

Other 'features lofthe invention will appear more articularly in the annexed specification, t ie claims appended thereto, and in the drawingain whic V Figure; represents the relay in side elevation., Fig. 2 isa plan view thereof. Fig. 3 is a fragmentary plan view with the. contactstrip removed. y Fig. 4 is a front elevation. ,i Fig.l Sis asimilar view with the angular end l' Referring to the. drawings, a indicates the i coil of the relay, .which 1s made up of the l usual line-wire windings mounted upon a iron core, which projects `a short vdistance from the forwardface of the bobbin to form the pole-piece b, while the rear end is exl tended and provided with screw-tlneads c,

are insulated from each other by the usual insulating-blocks Z. top of said bar d and terminates at a oint a said. strip is bent over the end of said bar. Contact-strip extends along the bar d and projects some distance beyond the end therei of and is bent down at right angles and terstrip being provided with a circular. orifice,

through which the upper end of stud p is passed to retain the strip in proper alinement.

The for-ward. end of the bar d is provided E with two laterally-projectingpins or studs g, serving as pivots for the armaturec,l which is i a rectangular stamping of soft iron, having a relatively long rear end @"running longitudicontact-strip h and bar d and serving to coun'- terbalance the forward end of the armature t and hold the platinum contact o thereon l against the point n of contactfstrip 7c.r

Near the bend of the armature are lateral depending .lugs or earsff, having notches or recesses in the lower edges which are slipped over and engage-the pinsg g, and it is to be noted that this construction affords an eiicient and convenient pivotal mounting Jfor the armature, permitting the latter to be i readily adjusted or removed by merely lifting contact-strip k and slipping the armature Strip 7L lies along the- 'little beyond the forward end thereo When nallyof and' normally resting upon the top of may bejquiclrly adjusted in position or re-'j l l on or off of' the pins g g and over the stud p.

VTo permit the armature to swing freely vbobbin or spool and surrounding the softl about the stud p, a section of the-former is cut away to forni a recess e, extending around said stud and for a short distancev into the front face of the armature.A The rent. To limit the movement. of the armature toward the pole, the insulation Z below strip 1c is extended to form a shoulder l',

against which the end of the horizontal portion e of said armature abuts as the latter swings upward.

In order to establish an eflicient electrical connection between contact-strip 7L and the armature e, a flexible U-section, of metal wire -or other good conductor,is secured by screws or rivets ifi, passed through suitable loops in the ends thereof and tapped into thearmature and the strip h, respectively, near the bends thereof.

In order to prevent the armature from being lifted off its pintles or pivots during ordinary use, the flange g on the post p is extended out, so that it overlies the rear edge of opening in the armature. It may also overlie the side pieces; but I find the former construction (shown. in dotted lines in Fig: 2) to be sufficient. l

Having thus described my invention, what. I claim, yand desire to secure by Letters Patent, is*

1. A relay comprising an electromagnet having a flux-bar extending longitudinally thereof, an angular armature pivoted thereto, and contact members carried by said fluxbar, one of which is electrically connected to said armature, and the other of which makes electrical contact therewith.

2. A relay comprising an electromagnet, having a iiux-bar extending longitudinally `thereof, contact members carried by said iiux-bar, means for connecting one of said contact members to said armature independent of the pivotal connection, and means on the other contact member which connects with the armature.

3; A relay comprising an electromagnet having a linx-bar extenonng longitudinally thereof, an angular armature removably pivoted to said flux-bar, a contact member, flexible means connecting said contact member to said armature, another 'contact'member normallyin electrical contact with said armature, and means supporting said last-named contact member and insulating it from said armature when the magnet is energized.

4. A relay, comprising lan electromagnet having a soft-iron flux-bar extendingralong the top thereof, insulated contact-strips extending along said bar, one of said strips having anangular end provided with a contact, and an angular armature loosely and liftably ivoted on said bar and having a contact at 1ts forward end coperating with the contact on the angular-ended strip, substantially as described.

5. A relay, comprising an electromagnet, a soft-iron flux-bar extending along the top thereof, insulated contact-strips extending longitudinally of said bar, one of said strips aving an angular end depending in front of the magnet-pole and provided with a contact, an insulating-stud on the forward end of said bar passing through said strip, serving to aline and space the same, and an angular armature loosely and liftably pivoted on said bar and between said contact-strips, said armature having a contact on its forwardl end cooperating with the contact on the angularended strip, substantially as described.

6. A relay, comprising anelectromagnet,

a soft-iron flux-bar extending along the top` thereof, insulated contact-strips extending longitudinally of said bar, one'of said strips having an angular end depending in front of the magnet-pole and provided withacontact,

" an insulating-stud on forward end of said bar passing through said strip serving to aline and space the same, an angular armature loosely and liftably pivoted on said bar and between saidt-contact-strips, said armature having a contact on its forward end coperatingwith the contact on the angular-ended strip and a flexible conductor connecting said armature and the other contact-strip, substantially as described.

7. A relay, 4comprising an ele'ctromagnet having a flux-bar extending longitudinally thereof, a pivot-pin on the forward end of said bar, an armature having a vertical and a .horizontalme1nber,. the latter extending along said bar and serving to counterbalance said armature, and depending lugs on said armature havingopen slots engaging said pivot-pins, substantially as described.

8; A relay, comprising an electromagnet having a flux-bar extending longitudinally thereof, contact-springs mounted on said bar, insulation spacing said springs, and an armature pivoted to forward end of said bar andl having a counterweight member extending rearwardly along said bar, said insulationv between the springs having a shoulder extending in the path of the counterweight member to limit the movement of the armature toward `the magnet-pole, substantially as described.
