To aZZ whom it may concern:

Be it known that I, EMERsoN R. NnwnLL, a citizen oflthe ,United States, residing at New York city, New York, have. invented certain new and useful Improvements in Elevator Signaling App'aratus, of which the following is a clear, full, and.` exact description.

My invention relates' to an elevator signaling apparatus in which a signal or signaling means is provided which is adapted to give a signal to either the operator of the car or the intending passenger, and to restore the same and the circuitswhich operate such signaling means' to normal condition, and which shall be Controlled (preferably at the several floors) by the operator of the car, preferably through operation of the gate mechanism, and my object is to provide a construction which shall be simpler and less eXpensive to install than the mechanisms hereofore used.

Prior devices which have been used have restored the signal circuits to normal condition solely by the operation of the doors or gates at the several floors, such, torl example, as the two Mcean Patents #MSOE and 748,409, and l believe that l am aware of all such niechanisms as have been in use or patented, but in most, if not all, of those in which the circuits are restored to normal condition merely by the floor gates or doors, it has been necessary to run at least one wire down the hatchway to each door. Thus in, for example, a twenty-story building, to run at least twenty wires down Vthe hatchway to the several gates.` ,This -inakes an expensive and objectionable construction, for the cost of installation inf an elevator signaling apparatus is a verymateriai factor in the ultimate cost to the' owner of the building.. lt is sometimesdesirable to accomplish the restoring to normal'condition of the circuits by the fioor gates, instead of solely by the commutator which is movec correspondingly with the morement of the car, because in the latter case if one car of a bank of elevators is full of passengers and cannot stop at a floor from which-a signal has been. given, the elevator operator must press a so-called transfer button? in the car in order to pass that floor and still leave the circuits and niechanism in condition such that the next following car will receive the signal land stop and pick up the passenger, but where the mechanism is such (as in said Mcliean patents) that the vcircuits are not restored to normal condition unless a fioor gate is opened, the operator, if his car is full, may run on down, or pass the fioor, and still leave,the,circuitsor mechanism in condition such that the next following car will receive the signal. o

l am aware that niy invention may be embodied in widely difiering forms, but in the drawings have shown a preferred embodiment of my invention which is applicable to an elevator signaling ap'paratus now widely in use and which is described in the Smalley & Reiners Patent #326552, dated July 2a, rece. f*- i ln' the drawing's, Figure 1 represents a diagram of two shafts and iioors with two commutators and inechanism such as illustrated in said Smalley & iteiners patent, with my invention substituted therein; Fig. represents merely the restoring circuits; Fig. 3 a diagrammatic view of a still more sinplified Circuit; and'lFig. a shows a modified form of the invention (mostly diagrammatic), and Figs. 5 and 6 are detail views of a portion of the same` 2deferring to Fig. l of the drawings, the third and fourth fioors of a building are shown with two cars A and B moving in their respective shafts, and passing the doors or o'ates 1, 2, 3 and a located at said fioors by which the intending passengers are admitted to the cars. 5, 6 and 7, 8, are up and down passengerls buttons at each fioor, which are devices to he operated by the intending passenfiers when wish to take passage in the car, and which are preferably the ordinary normally-open push-button switches comnionly used in such installations.

n the embodiinent shown in thedrawings, l have provided electrically-operated signaling means for signaling .to the operator of the car to stop at the floor where the push- "outton'has been pushed, and also separate signaling ymeans located at each floor for signaiing to the intending passenger which car is closest to himand moving in the direction he has signaled he wishes to go. signals are, preferahly, a single nal lamp 9 or 1G in each car for signaling to the operator, and up and down stationary signal lights outside of each shaft, such stationary signals being shown at 11 to 18 in pairs over the doorway outside of each shaft. It will be evident that either one of these two signaling means may be omitted without, varying the operation of the remainder of th device, and obviously they may be of widely differing constructions as will be evident to any one skilled in the art, as the main purpose `of a signal means within a car is to signal the operator to stop at a floor, and the signaling means for the intending passenger is to tell him which car Will take him aboard. It is also common in the art to use a series of signals the car, one for each fioor, as shown, for example, in Patent 634,229. The signals shown in the drawings' are, preferably, operable only when a car is approaching the floor, but it may not be desirable in all cases to have a'signal in the car given ony when the car approaches the floor at which the push-button has been pushed.

In 4order to determine the time when a signal can...be given, one of the floor pushbuttons must bepushed, and if it is desired to have a signal given only when a car approaches a floor (which is the preferable construction), a' so-called cominutator is used which, or a portion of which, is moved by suitable connection to the hoisting mechanism of the elevator, and therefore moved correspondingly with, but usually much slower than, the elevator and which renders a signal inoperative exceptwhen a car is approaching the fioor on whlch a pushbutton has been operated and is moving in the direction indicated by such push-button. The stationary portion of such commutator for car B is indicated generally by O, and by D for cai` A. The moving portions are represented by F and H.

The means for determining the time when a signal can be given also comprises signal controller mechanism corresponding to each floor which is represented as a whole by I prefer to provide only two of these signal controllers for each fioor one for the up direction and the other for the down direction, for the entire bank 'of elevators, in-

vstead' of providing a separate one, or a separate Pair, for each elevator; One such signal controller is illustrated, for example, by a mercury pot 19 and .switch armv 20, which latter may be dropped into the pot whenevei` a push-button is pushed. In the'4 construction illustrated in-the drawings, this -controller 19, 20, is, as hereafter explained, common to both the elevators, as it is cross-connected'to the two commutators. The switch arm is pivoted and normally held in its raised position by a pivoted detent 21, which normally] stands in the position in which detent 22 is shown. 23 is a setting magnet.

wardly, because it controls the up signals lf and 18, and also controls the signal within the car with reference to the fourth fioor,

because it will render said signals operative when4 the moving portion of the commutator ,arrives at its proper position, as hereafter explained.| 25, 26 is a down signal controller' corresponding to said floor, and alsof'set by its corresponding down push-button 7 and which controls the down signals 13 and 17, and also the car signals when theA cars are moving down- Wardly and approaching said fourth floor. 27, 28 and 29, 30 are up and down signal controllers for the vthird floor, which are similar in construction to the ones just described.

Referring to the specific mechanism shown in the drawings, each fioor is represented by one or more relatively stationary contact plates for each direction of movement of the car, for it will be observed that the down lamp 11 on the third fioor is connected to the contact plate 31, and the up lamp 12, to 32, and the up and down lamps 11 and 13 on the fourth floor are connected to the plates 34 and 33. Similarly, also, the up and down lamps 15 to 18 for car A are each connected 'to separate contact plates 35 to 38, and it will be obvious that each one of these plates' represents its own particular light or signal. 1 also preferably provide another lot of plates corresponding to the ones just mentioned and indicated by 39 to ati, inclusive, which. are connected to their respective'mercury pots in parallel. For example, the up plates 39 and 45 are connccted together and to the mercury pot 19, so that if arm 20 is in the mercury pot 19 the up "lamp 14 will be lighted whenever a connection is made from plate 39 to plate 3%. ft will be observed that there are normally two breaks in the circuit to-this floor light 14:, one at the' mercury pot and the other between the plates 39, 34, and this is the preferable construction, although'it is not necessary in all cases.

. The-moving portion of the commutator for car B is` indicated by F, in which the dotted rectangular figure represents a carriage for supporting andmoving the'brushes of the commutator across the relatively stationary contact plates. 47 represents a series of brushes which, when the car is rnoving up, will bridge the plates 3d, 39, etc., and 48, represents two pairs of brushes, which will bridge the plates 39, 40 and the long contact strip 49. As the car B moves upwardly, the brushes will move upwardly over the contact plates and bridge the breaks between 32 and 40, and then between 40 and 49. 4The upper pair of brushes 47 will strike the plates 34, 39 when the car reaches about the second fioorand will then close a circuit through the up lamp 14 to plate 34, by the brush to plate 39, tothe mercury pot 19, and back to the dynamo 49 or other source of supply, thus lighting up the up lamp, which will remain lighted because of the series of brushes 47 until the car reaches the fourth floor.

The signal 9 within the car is also controlled by the two pairs of brushes 48, the upper pair of which will'bridge the break between the plate 39, and the strip 49 when the car reaches about the third floor, for they will close a circuit from the dynamo 49,

` through the car lamp, and by the Wire 50 to strip 49, to plate 39, and back to the up fourth fioor controller 19, 20, thus lighting up the signalin the car when the car is approaching the floor on which the up push-button has been pushed, and it will be observed lthat the car signal will, in the embodiment shown in the drawings, be lit up (like the outside floor lamps) only when the car is approaching the floor.

In order to put the commutator in con dition to operate only the upll signal lights outside the shaft and the car light when an up push-button has been pushed (so long as the car is moving upwardly), and to prevent the giving of a down signal, (and vice versa when the car is moving downwardly) it is common in the art to provide a construction with mechanism which will accomplish this result. in the beforementioned Smalley & Reiners patent 826,752, the hrushes automatically shifteol7 when the car reverses its direction of movement, sovas to Shift the same froml the operative position shown at F in lTig. l, to the position shown at H, ,that is, when the car reaches the top of the shaft and starts to move down, the brushes 47 lare shifted so that they would not bridge between plates 34 and 39, but would travel over merely plates 39 and 40, and brushes 48 so that they travel upon onlythe strip 49, and the restoring brushes 51 rest upon only strip 52, thus putting them practically out of operation. Brushes 53 for controlling the down floor lights, as well as the car light brushes 54, and the GGdown restoring brushes 55 are shown in their inoperative position, and when the car starts to move down, they are shifted across to the same relative position as shown by the brushes 53', 54' and 56 of the moving portion H of the commutator at the left. l do not conslder it necessary to show the mechanism for shifting such brushes, as it will be evident to any one skilled in the art that it can be accomplished in a variety of ways. Thus it will be seen that when a car is moving upwardly, for example, neither the outside .floor lights, nor the light within the car, will be lit up, except in response to'the operation of an up push-button, and no signal will be given if a down push-button is operated.

ln order to restore the ircuits and the signals to normal condition after a signal has been given, l have provided a restoring mechanism which is normally inoperative to accomplish such restoring, but which is made operative for this purpose at certain times and which comprises a selecting device which is moved correspondingly with the carand which, when made operative, will select (because it moves correspondingly with the car) the proper signal controller which is to be restored, and l render the restoring mechanism operative by a switch device (preferably at each floor) which is under the control of or operable by the operator of the car, preferably through the operation of the several door mechanisms at the floors, such as by opening any door for the admission of the passenger. ln the embodiment shown in the drawings, stationary contact plates'58, 59 are provided,

which correspond to the third and fourth floors, and the pair of brushes 51 are in such position that they successively bridge the breaks between the strip 52 and said contact plates just as the car starts to leave the corre'sponding fioors. For example, when the car is at the fourth floor and starts to move up from it, the brushes will be in the position shown at the right of Fig. 2, that is, in such a position that they rest upon contact plate 59. When the'brushes so bridge strip 52 and plate 59, a circuit would be closed from strip 52, through brush 51 and by wire 57', to and through the up restoring magnet 158 of the up fourth floor controller 19, 20, and back by wire 59' to the battery, but it will be observed that said circuit is now open at `each floor at points G0, 61. Down each hatchway or shaft are run two wires, 62 being a common feed Wire from the battery, and 63 the return, which is connected to the feed strips and 64. lf any'ofthe switches 60, 61 are closed when the brush l'bridges the break between strip 52 and contact 59, the rcstoring magnet 158 will be energized. As, however, there is a restoring contact (such as 59) corresponding to each floor, and as the brush 51 rests on such contact only when the car is at the corresponding floor, and as the elevator operator can obviously only'open the door of the floor 'which the car then is, only the corresponding signal controller will be restored to normal condition.

Fig. 2 shows the restoring circuits of Fig. 1 without the remaining portions of said latter figure. Assuming that the 'car B has justpreached the fourth fioor and 1s moving upwardly, the brush 51 is then bridge ing the break between 59 and 52. fhen the operator opens the door 4 in the direction of the arrow, the stop will strike the switch 60. and close it, thus closing a circuit through the restoring magnet 158, which will draw the switcharm 20 out of the mercury pot and restore it to normal condition, and it will 'be obvious that at whatever floor the operator stops, he will restore the corresponding Controller, providing that said controller has been set and corresponds to the direction in which the car is moving. The contact plates 58, 59 are for the up direction of movement of the car. The corresponding contacts 66, 67 and the brush 55 are for the down direction of movement of the car, and with'the parts! in the position shown in the upper right-hand corner of Fig. 1, or at the right of Fig. 2, opening a door will not restore any of the down signal controllers such, for instance, as 30, 29, because the brush 55 is then in position such that it travels over only strip 64.

The commutator at the left of Figs. land 2 is shown in the position in which the car is traveling down. The down push-buton- 5 on the third fioor has been pushed and has closed a circuit through the down setting magnet 69, and has dropped the controller arm 30 into the mercury pot 29. When the brushes 53' bridge the contacts 35, 4-1, a circuit will be closed through the '*down light 15, andl when the brushes 54' bridge across from strip 70 to contact 4:4, a circuit will be closed through the signal 10 in car A. l/Vhen car A stops at-the third floor going down, brush 5.6 will be in the position shown in Fig. 2, and if the elevator operator opens door 1,'it will close a circuit through the down 'restoring magnet 71, thus restoringl the controller 80, 29 to normal condition.

In Fig. 3 1 have shown an electrical diagram of the restsing lcircuits showing merely the upr' restorlng contacts 58, 59, and brush 51 for car B and the up restoring contacts'? 5, 76 and brush 77 for car A. Tn this figure it is assumed that both cars are moved upwardly, that car B has justreached the fourth floor, and that car A is just approaching the second floor. The brushes are moving in the direction 'of the arrow of Fig. 3. When the operator of car B opens his door, he will close the switch 60, thus energizing restoring magnet 158, and when car A reaches the third fioor (moving upwardly), brush 77. would be on contact 75, and if he opens 'the third, floor door he would close the switch 5419, thus energizing up restoring magnet 80.

install than constructions such as used heretofore in which a separate wire, or possibly two or more wires, had to be run down the shaft to each doorway. As the restoring circuits are open at all` times until a door switch is operated, the restoring mechanism, is therefore normally inoperative, or unable to automatically restore` the signal con- ,trollers to normal condition, but the same can be rendered operative to restore the signal controllers by the operation of the door mechanism, and the movable restoring brushes select which signal controller shall be restored. As the commutators in Fig. 1 are the same as in said Smalley & Reiners patent, this invention may be used with such frm of commutator without any change whatever, as it is only necessary to connect the normally open restoring circuit to the corresponding restoring feed strips, as shown in the drawings.

The electrically-operated signaling means adapted to give a signal whenever a car approaches a fioor may, it will be observed, be considered to 'refer to a series of signals, or a single signal, because the series of up lights 12, 14, for example, for signaling to the intending passenger, are such, as is also the single signal 9 within the car. The ele'ctrically-operated signal for a shaft and car may also refer to either the signal within the car for signaling to the operator, or one of the lights outside the shaft for signaling to the intending passenger. The gets mechanism for Operating the restoring fioor switches, such' as 60, 61, may obviously be of widely varying constructions, for it will be obvious that any mechanism which is operated by the operator when he stops at a floor and admits the passenger/'and which would close the circuit, would accomplish some of the advantageous results of lthe mechanism shown as the preferred embooliment of my invention, but I prefer to have `the fioor switches closed by the door mechanism when the door is opened,l because it will be observed that when the door is opened to admit the passenger the switch 60, for eXamplewill-be practically instan- Vtaneouslyclosed and opened again, and if In Figs. 4, 5 and 6 I have shown a construction to accomplish the same general results, but in which the signal controllers corresponding to each floor, which are set by the .operation of the corresponding pushbuttons, are of a different construction. In such alternative construction each fioor is represented by two long bars, one for up and one down. One such bar 90 is indicated in Fig. 5. It is normally held slightly to the left against the tension of spring 91, by means of a detent 92. Then a pushbutton is pushed, it energizes said'magnet 93, withdrawsthe detent and allows the spring 91 to pull the bar a quarter of an inch oi' so toithe right, to the position shown, whereit rests against the stop 94. The bar carries a block 95 containing a springpressed plunger 9G and an insulated contact 97. The bar in Fig. 5 is shown turned over ninety degrees from that in Fig. 4, as Fig. 4 represents a plan view. Bar 90 is the up bar for 'the third floor, and in the drawings the up ush-button 98 is assuined to have been pus ed. Bars 101 and 102 representing the up and down bars. respectively, for the fourth fioor are in their normal position, but up and (lown bars 90 and 100 for the third floor are shown as having been released by the up and downl push-buttons 98 and 99. A. commutator device moving correspondingly with the movement of the car is also provided, consisting of a mechanism carried on a moving block 103 (Fig. 6) which carries on it the two cam portions 104 and 105, which press in the respective plungers at the proper times'so as to light up the lights in substantially the same manner as the moving portions of the commutator in the other construction. It will be observe'd that each fioor light is connected to a contact such as 97. As the cam 104, for example, moved upwardly, it would strike plunger 9G and move it just sufficiently to touch spring 97, thus closing the circuit through the up light 10 for the third floor. The links 106, 107, together with the slotted ends 108, 109 of the cams are moved as the car reverses its direction of movement to throw the proper cam into operative position. and the other cam out of operative position. Assuming the car at the left to be moving upwardly, the link 100 has thrown the cam 104 to its position shown, such that it will contact with the plunger 90 but will just escape the' corresponding.up plunger 111 of the up bar 101 for the fourth floor, (the up pushbutton on the fourth floor not having vet been pushed). The link 107 has thrown the cam 105 to its inoperative position so that it would not contact lwith plungers 112 or 113 even if both bars 100 and 102 were released. It 'will therefore be observed that when a push-button is pushed it will release a. bar, and when the cam corresponding to that direction of movement approaches, it will press in the corresponding plunger Vof that bar and light the corresponding light.

In order to restore the bars to normal condition. I have provided upon the same block which carries the cams, another cam or cams which operates upon the respective bars. In Figs. 4' and G, 114 is a cam carried on the far Side of the block 108 and which is rocked by means of a rocking rod 115 which passes through a slot 116 shown in dotted lines in Fig. 4. This rod and cam is rocked at the proper times by means of a toggle 117 actuated by means of a magnet 118.v On the bar 90 is a projection 119 in line with the cam and which' will be engaged by it so as to move the bar back to the position where it is engaged by the detent. The cam` normally stands in the broken position of the toggle, such as shown by the cam 120 at the right of Fig. 4. The

same normally-open restoring 1circuit as in Figs. 1, 2 and 3 is provided, the return Wire 63 of which is connected to magnet 118 When the car is moving up, for example. Then the cam 114 and its toggle 117 are in the normal position .(that is, in the position of cam 120 and its toggle), the opening of door 1, for example, will close the circuit through the magnet and draw down the core 122, cause the upper end of the slot 123 to strike pin 124 and throw the toggle down to the position shown at the left of the figure. When the car is standing at the third fioor. the cam is in such a position that the cam 114 is about to engage the stop 119, and as the car moves up the cam will move the bar back to normal position and the spring 125 will move the plunger out of engagement with spring 97. The cam will engage the block about -at the point indicated bv the dotted line at the right of the pivot 127, and will move down the face of the cam until the detent again engages the lug 128, which will occur just before 119 passes to the left of the pivot 127. vAs 119 passes onto the left end of the cam beyond the pivot, it will cause the toggle to break and the same will be thrown up into its broken position, which will draw the cam back to the position indicated in dotted lines at 129, that is, to such a position that it Will just escape contact with any other ,up bar (such as block 180 ,of bar 101) even if the same had been released The cam is therefore normally inoperative to restore the bars to normal condition, .but is rendered opera- -tive bv'the opening of a floor gate.

In order to operate the other cam 131 for restoring'the down bars, a similar magnet 132 is provided. together With a switch 133 which is automaticallv thrown from the position shown to a position such that the return wire 63 is connected With the Wire 131 when the car reaches the top of the shaft and reverses` its direction of moveinent. Then the car starts down, the cain 104 and the magnet 11,8 withits cam will be out of operative relation, and. conversely, the cam 105 with its'magnet 182 and toggle cam 131 will be in condition to give vthe down signals and restore the down bars. The car for the shaft at the right is also provided with' similar signal-controlling cains 136, 137 and restoring cams'lO, 137', magnets 138, 139 and switch 110. It will be obvious that the operation of this construction is substantially the same as in the construction illustrated in Figs. 1, 2 and 3. The construction at the right of Fig. 4 is assumed to be in the position in which the car is moving downwardly, one of the gates having been opened to thi'ow the cam 137' to its present position. o

It will be obvious that my invention is applicable to other` forms of apparatus than herein illustrated as the same may be widely varied, and I therefore do not confine my- Self to the construction illustrated.
