To all whom it may concern:

Be it known that I, FELIXBENEDlU'T Henzoo, Ph. D., a citizen of the United States, and a resident of the city, county, and, State of New York, have invented a new and use" ful Improvement in Electric Signaling Apparatus and Circuits, of which the following is a specifintion.

My invention, in its fullest embodiment, consists in means for signaling from various floors of o,b11ilding to two or more elevetors in such n. manner that theeondnot-or of each car is informed whether the Waiting passengegmzishes to go up or down, and also whether any other conductor has on Led the call, {ind-it also enables each cofriouotur to signal to the Waiting passenger that conductor is about to respond to the l n tion, and also enables eeeh conductor to dicote to the other conductors.

Inthe drawings Figurel is at rear w of the operating parts of the calling box at the stations or floors; Fig. 2is a side sectiomend Fig. 3 o front View ofthe seine. Fig. 4: is a general diagram of the circuit arrangements and the general organization of the system. Fig. 5, a similar diagram, the individual circuits being multiplied as they would be in a system using four buttons. Fig. 6 is n detail of the short-eireuiting hell oi the Well known type, and Fig. 7 shows details of the box shown in 1 and 2.

Referring to the figures in cletnil:--ln Figs. 1, 2, and 3, a chlplieote arrangement is shown; the ports of the Up and Down buttons, respectively being similar. The corresponding parts on the lower box bear the same" letters those on the upper but have a prime :1 ddecl thereto. In the description a port will he mentioned either with or without the prime according to which View of the partreferred to is most e: sy to find. By pushing either button part lrl fixed to shank P is brought into Contact with the Contact spring E, which normally rests in position against an insulated pin, 0. Fixed to the shank is the cum with two ends, the one enclli, preferably making the contact with F when it is notconi'enientto bore this made directly by the shank P, and the Second end X acting to look the button in its depressed. position henever a current. through magnet M holds the armature E against the poles. The iii-mature or an eye tension shows through the window in the front plate in such :1 inanner that its posi tion or its changes of position may be observed from the front of the box. In the Up part of the box the armature falls on 2 common to the general feed wire 19 (s wzuin heavy lines}. Tlhe other feed wire or pole connects to this first wire by the res eetive individual or floor Wires-f ojoown in multi lie in Fi 5-there bein 75 to 7 V t! one of these for each button, and. th ae end for each button----ou top of the insulated stud T for the down and T for the up cells (Fig. thence go to spring 0 (or C}, magnet, and. contact cult is completed on that particular button is pushed. Spring C is fixed to an insulated block arranged in any suitable innuner. in Fig. if the shape of spring l is changed so on to make theillustrntion 85 elenreiz The individual wire for enrh hutton ends in 1: spring I? after passing through its .ningnet; hence, when the button is pressed and current is in line, :1 Contact is parts (including the frame s in any box, and. in oil} of the boxes they spring F where the cir made at l and current through he magnet will reuse the armature to stick to the poles of M and will thus cause the button to non tinue the oontiurt until uirruit is broken at the distant siui'ion, whereupon the :umuturo permits the spring 5,: in res-lore the button 95 contact. The unumor of produrring this x11} 'y -'1 i} 6 mi m- 7} i l)l(l\lll loner]! )h when... l uspuug (l Wllltil is lined ton suitable insulated block seen in 1 1g. .1. warn cause Contact box is fastened to its base. thus permitting of rapid unfosteuing and ins 'usotion oi. ports and re-eonneoiion when box is fastened by. the, suitable devious shown ihheiihoy thunl d actor w hose shown, of a character in which the indichtion continues only as long the current flows, and are automatically restored upon the cessation of the flow; thus in the ease of the magnetic form, 12, the armature is attracted lo the magnet upon closure of the circuit at the button, and continues attracted until reatored, (by the spring indicated, or else by gravity, as it would be in the posh lion shown) as; soon the current interrupted or suihciently weakened; and in the cane oi the lamp the glow would begin, eont'nue and. cease. under like conditions. It

evident that with suilicient current any.

" to the operator whieh button it was that has been depressed and consequently which floor has eigjmiled. each annunciator indicate tors corresponding to a given button sl1oul.d be located in a similar position and the c0rnaroondinelj cut-ou switches should for connience be placed in close proximity to the "indicator of the line to which they belong.

is obvious that in the form selected for illus ration every indicator in series on a wire will. operate simultaneously, and therefore every conductor would siinultaneouslv linow that a given. button had been pushed;' for instance. thelmtton'on. the (3th lioor marked to irulicatc that a. passenger wished to be taken up. But it. is not ueceaeary that all conductors should respond, and the conceit would be in a position which would make it proper that; he should he the n to take a passenger under those conditions would therefore ordh'iai'ily be the only fnoper one to respond, whereas the conductor or eomluctors oi the other car or cars, although they would know that a call had oer-u sent from that point. by a passenger wishing to go in that direction, would disregard it Ililltf-HS they had reason. to believe that the conductor whose duty it was was not in a position to perform that. duty, or had neglected it. in (other .vords--it is, of course, obvious that there no intention of havi more than one car stop to take one passenger. who has signaled :trom. a given floor, the intention being to eecure as the final result oi the operation of the organization an a whole, and by wljiich all the ears receive the signal, that which is set forth in the printed instructions to the aiting pas--' senger which are ordinarily displayed on the front of the floor box in the manner shown in the illustrationThe first car to its normal condition 'tion,un'der stressof the that passes in the direction indicated will stop for you. By giving the required in formation 5imultanemisly lo'all cars the result is secured that it the first car about to pass in the desired direction should not be available For any reason, as, for instance, should be moving at such speed as notio be able to stop in time, or should be too full, the next car could respond and thus the passenger can give the effective notice in connection with a group of cars, by the act of operating one signal only as against the necessity of operating one tor each car as it. existed before my invention.

During the entire time that the indication corresponding to any floor is thus displayed in the cars, the corresponding button remains held in place as the result of the magnetic clutch. described. The proper conductor as soon as he \viahes to respond gives a tap upon the button of the cut-out switch, 14-, thus opening the. circuit, wlu-u'eupon three distinct ellerls are produced first. the indicator corresponding to that. particular liuois restored (no matter how many other indications may be showing: from other floors at the time) second, the answer bark or return signal is given to.the passenger by the u'ierliauical click which he hears as his button is returned to its normal position under stress ol the spiral spring S on the shank (and at the same time the shutter is displayed as indicated on the directions in Fig. third, the corresponding indication disappears in the other car or cars, thus indicating, to the other conductors that there is no longer need tor them to pay attention to that particularcall.

I It will be noticed, from the construction of the push button box parts, that the act of pushing the button results electrically in the contact between the piece ll aud the I spring l and also mechanically 1n permitting the approach of the armature to the poles of the magnet by gravity in the case of a magnet placed the Up button is placed, and by the aid of the spring K where the armature naturally falls away from the magnet, as in the Down button.) This approach in eith r case is due to the fact that the lllClllliit-LOII of the cam X is such that as the button returns to its normal posihelical spring S, the slope of the cam will force upthe armature while rocking it upon th pivot which supports it in the frame as shown. This particular motion is of course not essential to the general function of the box, nor is the particular form of box or push button controller which is ehownessential to the operation. of the invention butthis special form has been illustrated and Selected in the present embodiment of the invention because of the simple mechanism-required to make it 4 oo-wee possible for a very small amountof cursrcn'i; vto produce the clutching cllecis upon the to the pole will make ii possible for a current to hold the armature clown in spite of the force exerted upon-iii luicrally the cznn, Whereas ihe seine cui'i'enl coulcl no; poesihly energize the magnet sullicicnily lo enable the uttruclioi'i upon the arnnziuire to cause the latlci' i0 depress lhe bul ion. ll is obvious, limt when in paseengeiwho h pushed a hutfon, ilc ircs to canc the cal ihc bution (tho lan e l he merely pulls O] a of which prevents it from sinking heyom his reach) and, as merely the slight me neiic alll'uction 21ml {he friction of ihc hni hold it in, a barely perceptible pull will store the billion contact and the normal c1rcuit conditions.
