Specification of Application med Marche,

T all whom t may concern Be it known that I; MAURICE- LnvIsoN, a citizen of the United States, residing at Chicago, in 'the cbunty of Cook and State' of "I'lli'nois, have invented certain new andl use- ":t'ul Improvements in Annunciator-Cabinets,

of which the 'following is a specification.

My invention relates to' improvements in annunciator cabinets, and particularly in some of its features t'o annunciator cabinets vvhereiii' electric lamps are used 'for effecting "'the signal display. V

One o the objects of my invention is' t 'provide ailnshvtype, all-metal cabinet constructlom 'which is simple, easily manufac "tured, fabricated largely of a plurality of similar partst'and susceptible of embodiment lin neat. and 'attractive form.

A further object' of my inventionv is td 'provide a construction ot the'cha'r'acter described, vtherein all of the lamps, and their associated parts, are mounted on a unit lamp-base structure adapted, when in use, to be fixedly secured Within the casing, but adapted, also, to be moved with respect to the casino to a position giving ready access to the wiring terminals at the back of the lampbas structure. Another object of my invention is to p'ro-, vide improved means for mounting the lamps and for :conining'the illuminating efl'ect of each lamp to its appropriate lens, so that false illumination of' any annunciator targets other than that directly associated with the energized lamp may not occur.

Still another object of my invention is to provide an improved construction, arrangement, and'mounting of the lenses associated with the lamps, and of the designating char- 40 acters or indicia `Which are associated With lenses. A particular 'object of my invention 'in this regard is to provide such construc-` tion that the designating indicia of the sev-,y eral lenses maylnot be visible except when' illuminated from the rear, as upon the glowing of the respective lamps associated there 'ivithl l Other and further objects of my invention will become apparent to those skilled in the art from the following description taken in 'conjunction with the4 accompanying'draW-- 'ing in which I have illustrated, for purpose' Letters'latent. 'Patented Sept. 1, 1914. 1914.' serial naszaols.

rinvention 'that is 'parti'cul'arl'yl adapted "for li'ospitals'ignaling service, and that I have i'ound 1n practice to be satisfactory and ellicient.

I n'the drawings'Figure 1 is ia front elevafion With' parts"broken'ayvay'sliowing a Hush-type Wall'cabinet' 'constructed in accord'ance 'ivith'my' invention; Fig. 2 is a vertical section on line 2 2 of Fig. 1,' 'With parts bioken away.' Fig. 3 is a horizontal, section on' line 3-#3 of Fig. 2', showingbne 'lens and its indication in s'ection's and the ther'inel'evationf Fig. 4 is a transverse 'section on lin'e 4-4 of Fig. 1 showing the cabinet 'open and the 'lamp frame" unit l'ru'rned to'position to expose the lamp `Wiring terminals.' Fig. '5v is'a'n enlarged rear elevation on line 5 5" of Fig. 8.' Fig. 6 is an enlarged perspective view of an index unit. Fig 7 is an enlarged perspective detail illus- 'ratin'g theihounting of the lamp carrying ase.

' In' thel particular' construction shown in the draiving's 10 indicates a'ivall plate or border frame having an opening 11 closable by a door 12, 'hinged at onefside, as at 18, and prbvided with any suitable lock or latch 14. Associated With the border frame 10 is a' box member 15, preferably of a single `piece drawn metal constructiom provided at suitable 4points with knock outs 15 to admit the requisite Wiring of said box having its'face opening fitted' Hush against the 'rear face of the 'latelO and having at its corners lugs 16 bo ted' asat 17 to said plate. In 'hospital installations and the like the entire "e'i'terior surface of the wall' plate' and door taking through said parts are concealed. The' d'oor or 'closure 12' has cut therein, in

'in vertically alining tiers, 'apertureslS in which are mounted the lens structures, each of which is generally indicated at 20.' Each lens struc-turepreferably comprises 'the plano-conveniens 21, having its planar surface ground and its 'curved surface clear.

This lens is" mounted in a holder 21 comprising a rirn' 2Q and 'a tubular body 23, said rim underlying a border portion of the pla- I'nar surface'of'the" lens and spun'over its "c'nveir border, andy said tubular body in'terof full disclosure, an embodiment of my fitting With the aperture 18 and extending are enameled so that all the screws and bolts I any suitable relative arrangement, generally through and beyond the door pleite 12. In the tubular portion 23 are formed retaining spring fingers 24, which, when the holder is in place, act. against the rear face of plate 10 to retain the holder in position.

I prefer that the distinguishing indicia associated with the respective lenseswhether numerals, letters or the likebe mounted in border frames detachably connected with the lens holders-so that the respective indicia of the diierent lenses may be changed or transposed as desired. In the particular construction shown (Figs. 5 and 6) 25 represents in general the indicating unit consisting preferably of a translucent disk 26, of mica or other suitable material, bearing an opaque index mark 27, which may be a black paper numeral pasted on thedisk, said disk mounted in a rim frame 2S adapted for insertion and selt retention in the tubular portion of the lens holder. Specifically 29 and 30 indicate opposing rim rings, ring 29 having projecting rearwardly therefrom a set of retaining spring fingers 31, adapted to make Jfrictional engagement with the interior surface ot the tubular member 23 of the lens holder, and also havinga series of clamp lingers 32, which are inturned over the edge of a complemental border ring 30, so that the two rings 29 and SO, united by the fingers position and reinforce the translucent disk. Manifestly the index unit 25 may be inserted in any lens holder so that the mica disk is brought close to the ground planar face of the lens and the indication 27 is thereby properly positioned. When light falls on a lens only from the front; as when there is no illumination within the casing, the numerals 27 are substantially invisible; the ground planar faces of the lenses making them appear frosted when viewed from in front. But when illuminated from the rear the numerals stand o`ut boldly, as does the numeral 3;, in Fig. 1.

A lamp is provided Afor association with each lens, and these lamps and their appurtenant parts are mounted on a vsupporting trame suitably secured within the housing. In the specific construction shown I provide upper and lower pairs of clips or angle-brackets, 40, forming vertically alining couples having their vertical legs riveted or otherwise secured as at 41 to the wall plate 1() adjacent the upper: and lower edges ot the opening 11. llachjsaid clip extends past the edge of the door opening to form a stop for the door and jis rearwardly bent to provide a horizontal :supporting surface. WYhile I preferably provide four of these supporting clips 40 for a cabinet structure of any ordinary size, more may be vided` 1t required, in extreme cases.

pro- The lam -carr Ying base or carrier 42 is a metal l ertures plate having its upper and lower edges for.- wardly bent to form flanges 43 intertting neatly between the supporting flanges oi the brackets 40, and ypreferably having its vertical edges rearwardly bent into flanges 4.4, for strength and to prevent buckling. Plate 42 is preferably mounted on the clips by detachable fastenings such as vertical bolts 46, so that by removing the bolts from the upper and lower clips forming the couple on either side of the median vertical line of the structure, the lamp plate 42 with all of its pertinent parts may be swung pivotally upon bolts, as best illustrated in Fig. 4. Specifically each liange 43 is slotted as at 45 at right angles to its forward edge, and the bolts 46 taking .through brackets 40 and the slots 45 s'ecure the plate structure in place. Manifestly such connection gives the plates a susceptibility to adjustment toward and from the Jfront 'of the casing, and as shown in Fig. 4 the removal of one couple vof the bolt connection 46 enables the plate structure to be swung on the remainving couple of bolt connections as a pivotal axis` so that the plate structure may be swung out through the open doorway to reversed position exposing the rear side of the plate outside of the casing to facilitate the placing of the electric wiring. To this end Iso proportion the plate and the parts connected therewith that they may be swung through the open doorway 11 without hindrance.

Each lamp 50 carried by the plate 42, of course alines axially withits corresponding lens 21, and each is inelc'sed within a shiel'd 51, to prevent diffusion of the light, each such shield preferably extending close yto the door 12 and preferably overlapping, in a fore and aft direction, the inner end o the tubular portion 23 of the lens holder. In the speciic construction shown the shields 51 are drawn metal cups, the base of' the cup and the plate 42 being suitably apertured to receive the insulated body of a lamp socket or receptacle 53, which extends suitably in rear of the plate 42 to expose its wiring terminals 54 at the rear ot' said plate. As best shown in Fig. 7, each lamp socket body and the shield cup appui-tenant thereto may be secured to the base plate .42 jointly by bolts 55. Manifestly the fore and aft adjustment of plate 42 permits the front edges of all oi? the shields to be brought as close as need be to the rear face of the door.
