Applioation Med November 21),'1909. Serial No. l529,115.

To all whom Be. it known that 1 XDAM Linex-:tsk ii iitizen of the United States, residing at the oitv of New York` in the hm'ough of the i Bronx and State-of New Yi-u'k.I have in vented certain newond usetul Improve ments in Aniuineiators` of which the follow ing is a full. clear, and exim-t desei'll'ition.

My invention relates to annuii'ieiators und 5 inoliiilesl several improvements` over tlieordinary eoiistrnetions' of :iuiinni-iutois` non' in use.

'llu'l :iini luis been to so arrange the several parts as to prodiiee :i compact ande-x- 15 eeedingly sini )le strutuie. the 'reduction in 'oost ot' mann aeture ot' which pre1' those of a similar type being considerable.

'30 Inthe drawings: Figure'l is a siileeli-vation' of un `anniinciat-or enihiidyii'ig;I the prineiples of my invention, Fig. 2 is a `similai-yiew showing the shutter indropped `or indieating position.

The lree )er is substantuilly L-sliaped` one. leg' oy the L beingr -fornied bythe back plate 3, and .the other 'by the bottom platet'. The forward end of. .the bottom plate is provided with depend- -iing v,lugs v'niindian L-shapeil' -fi-)r-wai-illy prolat J on Ythe i'espei'stve' sides, wliii-li flanges -pivot for the armature plate 15.

The hase plate is perforated M ll. for the reeel-)tion of .sx-rew 1-2. wlii-i/rli serene engages the eore on eleotio-magne lil, hold ing the saine firmly in position upoin'tlu- The lugs 7 `are perforated and a pin 14er:- tends therethrough, said pin serving as` a A flat spring 16 holds said armature normally away from' the electroemagnet, the tongue 8' forming an* abutment against which the lower end of the armature normallybears. The up er extremity of the armature is bent-to orm a lip 17 (Fig. 3) which main' tains the shutter or drop 18 1n its raised or non-signaling position. U-)Ward increment. of said shutters is arresto by the wings before mentioned. The shutter iszpivoted upon a pin 19 which extends through the walls 10, and is 'provided with lips 20 which' serye to'reta'in a signaling card insertible therebetween the shut-ter rests upon fingers or prongs 21 which extend outwardly from Athe iliigs 7,l and it is hence apparent that tlieshutter movement is limited downwardly by saidV prongs and upwa'rdly by Wings 5. The keeper is offset from the. supporting. ears 2 in the manner aforesaid in order that the termi-nal wires 22 of the electro-inagnetinay :be positioned thereunder.

The operation ot the device is as follows: Shutter 18 being in its raised. position as shown in Fig. 1, is supported by lip 17jof the spring pressed armature. 'Upon energiz ing the` inagnet, 'tliearmaturg being 4drawn thereto, Wil release the shutter which fall- -ingby gravity'will engage'tlie Vsupporting vsuppo'rtlng, attaching and! llimtin van armature, an. electroifmagnet an' ter. The keeper: fraruetherefore performs'- prongs .21, The shutter niayfthen4 vbe returned tov its non-signalingA positionv by any 0f the Well known means eominon'ly einployed for this purpose. It will-be particularly noted that the L-sliaped keeper is/ formed integral Withthesecuring ears"2, arrestin Wings 5, and the abutting tongue. 8, all o said Partsbeing struck up 'ironic-a ln its doWnu-ardposition.

comnion'plate. By this'construction'theessential parts of the device are redueed to a' fra-me, I

a variety of functions, to wit, it supports the magnet :1nd Iprovides :t path for the magnetic flux, it affords a support for the pivoted shutter and armature, it provides supporting or securing means whereby the' device :xs u whole may he supported from n wall or other surface, and finally affords limiting devices for the armature and for the shutter.

Whatl I claim, is:- i

l. In an annunciator, an electro-magnet. an armature, adA shutter and a. sheet; metal keeper carrying said magnet, armature and shutter, said keeper having supporting au electro-magnet, an armature therefor, a shutter and a sheet metal keeper carrying said magnet and armature and having a downwardly ydisposed limit-ing abutment for said armature struck np therefrom.

3. In an annuneiator, an electro-magnet, an armature, a shutter and a sheet metal keeper carrying said magnet, armature and shutter and Vhaving rearwardly disposed sup porting ears, upwardly disposed shutter limiting means and downwardly disposed armature limiting means struck up therefrom.

In Witness whereof, I .subscribe my signature, in the presence of two Witnesses.
