ings accompanying and forming a part of the same.

This invention relates generally to signal apparatus in which a person at a glven point or station can'cause a ortion, normally in an inoperable condition, to move or be put into an operable condition and a signal to be given by the movement of a car or similar moving object as it approaches a given point and to restore the parts to their normal condition.

Among the objects of the present invention are the provision of an apparatus or signal system which is simple, practical and eliicicnt as compared with prior devices, and

5 one of the other objects is to improve generally the principles of operation of the system and parts thereof.

Figure 1 is a diagrammatic view illustratirg how the circuits and other parts iereinafter set forth; Fig. 2 is a front view of portions of one embodiment of the invention showing the mechanism or means arranged at a central or common point for bringing the circuits into and out of opera le condition and by which the circuits are closed. when operable, and signals are given accordingly as the car or similar moving object reaches predetermined points in its travel; Fig. 3' is a partial side view of that shown in Fig. 2: Fig. 4 is a cross section on line 4'4 of Fig. 2. showing the parts for giving-either of two up signals in the positions they occupy when the circuits are in an inoperable condition and ready to be brought into'opcrable condition by energizing the electromagnet seen at the left by suitable means properly arranged for this purpose; Fig. 5 is a cross sectional view similar to Fig. 4 showing the parts seen at the upper right hand portion of Fig '2 for giving either of two down signals, such parts being in the positions they occupy when the circuits are brought from an .in-

operable condition, as seen in Fig. 4, to the.

operable one, where either signal can be given to the full extent desired and such parts may be restored to positions corre' sponding to those seen in Fig. 4 and the circuits be put into an inoperable condition; Fig. 6 is a side view of the devices for three different circuits and signals, as seen in Fig. 2, but on an enlarged scale and with some of the parts in ditl'erent positions from what corresponding partare seen in Fig. 2; Fig. 6 shows diti'erent means for movin the movable portion of the carriage into and out of actuating position from what is shown in preceding figures; Fig. 7, shows, on an enlarged scale, part of one of the switch devices seen in Fig. 6, with portions of some of the parts broken away to better illustrate certain features of construction; Fig. 8 shows the bottom portion of what is shown in Fig. 7, but turned one quarter around with that which is broken away in Fig. 7 shown in full; Fig. 9 is a top view, part] in section, of a portion of one of the swito devices seen in Fig. 6, but on the scale seen in Figs. 7 and 8, illustrating the manner of mounting the movable parts on their supports and of the two arm springs which normally hold such parts in position to be actuated by the means provided for this purpose; Figv 10 shows a different form of means connecting the movable portion of the carriage to the armature of the electromagnet by which such portion or portions are moved into their active positions relatively to the movable parts with which they engage and which are there mounted on supports; Fig. 11 shows in front view portions of a somewhat different embodiment of the present invention from what is shown in preceding figures. the signal devices. circuits and means by which the signals are given and the circuits are brought from an inoperable to an. operable condition being diagramunitically shown; Fig. 12 shows in cross section and on an enlarged scale portions of one controller. the means by which it is moved into position for bringing the circuit or circuits into an operable condition seen at the lower left hand portion of Fig. 11. and with the parts in the positions they occupy when the ei"cuit or circuits are in an inoperable condition: Fig. 13 illustrates one of the movable parts. the two arm spring by which it is normally held in position on its mounting, and its relation to one of the terminals of the circuit when such circuit is brought from an inoperable to an operable condition; Fig. 14 shows a modified manner of mounting the two terminals of a circuit which are to be closed by the movable part mounted on its fixed support; and Fig. 15 shows a construction wherein two movable parts mounted on a single fixed support and two separate switch devices are actuated, one by each of the two movably mounted parts.

In Figs. 1 to 9, inclusive, one embodiment of the present invention is illustrated and wherein each circuit closing or switch device is provided with a support or controller, which is spring actuated in one direction, that is, as here shown, in the opening direction. As here shown the opening direction is the direction the controller or support or supports move to bring the circuit or circuits into an inoperable condition, that is, a condition where the circuit closing devices are out of operative relation with the parts which ccact therewith to close the circuits to give the designed signals. Also, as here shown, two of these individual circuit closing or switch devices are so connected together that both are acted upon by one means to bring such devices into operative relation with their coacting devices and both may be returned to their inoperative relations to such devices uponeither signal being actuated, that is, by the actuating devices which first reach the actuating position to actuate either one of such devices, close the circuit and give the particular signal. Any number of such circuit closing or switch devices may be thus connected together that is desired, or there may be only a single one used, as for instance, when only a single car or similar moving object is to be signaled. There may be two of such circuit closing or switch devices for each car, or other object, at each floor or station, except the first and last, from which signals are to be given or received. One of these devices is for giving signals as such car or object moves in one direction and the other as it moves in the other direction, and for convenience may be designated as up devices, for up signals, and down devices, for down signals. As many of the up devices for any given floor or station, one for each car or object to be served, may be connected together as one desires and when connected together, as shown, they may be, actuated or moved into the operable condition or relation by the use of a single push button device, of ordinary construction, and clectromagnet, as indicated in Fig. 2, where electromagnets are seen connected with push button devices, there being one push button for each floor or staticnfor up signals and one for down signals, which are to be served and from which signals are to be given, by the use of such devices. Also, as shown, each circuit closing or switch device is provided'with a'retaining device to hold or retain the same in operative relation to the movable coacting parts, by which the circuits are closed, until it is desired to return or restore such devices to an inoperable relation to such parts and ren der them inoperable bv the designed movement of such parts, when such retaining devices arc actuated by suitable means and the circuit or circuits are restored to an inoperable condition. As here shown two of these retaining devices are connected together in such manner that upon actuating one the other is actuated and both of the switch devices are restored to their inoperative relations to'their coacting parts. There may be as many of these retaining devices as there are switch or circuit closing devices, thus or otherwise connected together, so long as they are operable to retain such devices in position to close their circuits, as hereinafter described, and to restore such circuits to an inoperable condition. These individual supports or controllers for the circuit closing or switch devices and retaining devices thus shown are more fully set forth in an application filed contemporaneously herewith.

As shown in Figs. 1 to 9, inclusive, each support or controller carries two pairs of contact springs or terminals, one pair for one circuit and the other pair for another circuit,,t-he two pairs being insulated from each other, but they may have a common source of energy, as is wellknown. If desired there may be a single pair of terminals for a single circuit or a single terminal of a pair carried by the controller, accordingly as one chooses to arrange the circuits to render them inoperative or operative. So long as each controller or support carries one terminal of a circuit such terminal may be moved into and out of operative relation to thecoacting parts and the other terminal of that circuit and such circuit be brought into or out of operative condition, or into or out of condition where their respective signals may or may not be iven.

Fig. 1 diagrammatically illustrates the arrangement of the switch or circuit closing devices, the circuits connecting such devices to the source of energv for two cars or similar objects, there being eight floors of a building, or stations indicated, two series of station signals for each car. and a signal in each car. One series of station signals are for up signals with which the up" devices are connected and another series with which the down devices are connected in each car. The same signal device is employed in the car to give signals in both the up and down directions. The switch devices are represented by small dots, one dot for each terminal of each circuit, and hence four dots represent one of the switch or circuit closin devices seen in Figs. '2, 3, &c. A, A, A, &c., represent the up and A, A, A, A, &c., represent the down signal switch devices of each of the two cars, as they are the same in each case. Each switch device has two pairs of terminals designated, as follows: for switch device A, the pair for the station signal as a and for the car signal as a, device A, the pair for the station signal as a and the pair for the car signal as a", and so on and device A, the air for the car s gnal as a, and the pair or the station signal as a, and device A, the pair for the car signal as a and the pair for the station signal as a, and so on. For clearness of illustration the switch devices for car H have the pairs of terminals designated and for car H the designating characters of the devices themselves are used, and it is to be understood that the switch devices and pairs of terminals for the two cars are duplicates of one another. These switch devices are diagrammatically shown in Fig. 1 and the manner of arranging them relatively to one another and the other parts is seen in Fig. 2. Only a part of them are fully shown in Fig. 2, the others being indicated by lines inclosing rectangular spaces, the better to show this arrangement of the devices relatively to the arts which serve to close the circuits. nly one of each pair of terminals is fully seen in this Fig. 2, as it is a front elevation and the other member of each pair is underneath the one shown, as indicated in Fig. 3. As shown in Fig. 2 there are two carriages B and B. Carriage B, Fig. 1, is connected with the actuating mechanism J of car H and carriage B is connected with the actuating mechanism J of car H, by any well known speed reducing mechanism, and suitable flexible or other connections, as j and 7', so that such carriages and the switch devices may be placed in any con venient location desired, and each carriage will move accordingly as the car moves with which it is connected, the switch devices being arranged at the proper intervals in the path of movement of the carriage to give the signals at the desired points in such path, as for instance where stations or floors are located. Each switch device consists ofa suitable frame or support N,

Fi 7, in which is mounted a controller n,

which is movable in two directions and carries one or more terminals of one or more circuits, and means by which the controller is moved. As shown, the controller n, is actuatedin one direction b a spring 11 and is actuated in the other direction by an elbow lever, as h or k, 4 and 5, connectin therewith, which lever is in turn connecte with an armature, as m. or m. This armature is attracted by an electroma 'pair seen, but not shown.

et which is to be energized in any desire manner. The spring n constantly tends, when arranged as here shown, to move the controller into the position where the terminal or terminals of the circuit or circuits will be in an inoperable position. The elbow lever has to overcome the stress of this spring n, when the controller is actuated in the other direction. This spring, n, at one end rests against the shoulder formed on controller n and at the other end against the frame N and, hence, the stress of this spring tends to move the controller into the position seen in Fig. 7, which is the position where the two airs of terminals are out of o rative relations with their coacting parts esigned to bring each air into contact and thereby close the circuit or circuits and give the signal or signals. This controller is reduced in size at the end where spring n goes, as shown, and enters a round opening in a rtion of the frame N, so as to move there- 1n. At the other end of this frame two cars N, N are formed, as more clearly seen in Fig. 8, between which the other end of the controller is received and it is held between such ears by the slot n, in that end of the controller, and pin n passing through the ears N N, as indicated in Figs. 7, 8 and 9. To this controller there is attached a piece of insulating material, as n, Fig. 6, upon which is mounted the two pairs of terminals or contact springs, as indicated in Figs. 2 and 3, one pair of which is seen in Fig. 6 and is there designated as a", the other pair for that device bein back of the 0 frame N there is pivoted an elbow lever h, more clearly seen as h in Fig. 5, or as h in Fig. 4, having a slot n in one end, which ongages with a pin n fixed on controller n. The other end of this elbow lever is is pivotally attached to a link is, which in turn is attached to an armature m of electromagnet M, Figs. 2 and 5. In Fig. 4 two of these elbow levers h are shown as pivotally attached to link b, so that both move at the same time by moving link h by armature m. The springs n, Fig. 7, one of which is also seen in Fig. 4, tends to hold the link It in the position there seen and this link is moved against the stress of these springs n from the positions seen in Fig. 4 to those corresponding to that seen in Fig. 5 by energizing magnet M. In Fig. 5 the parts are seen in the position they occupy when magnet M is energized. Thus the spring n, the elbow lever h, its connection. with armature m, this armature and electromagnet, form means by which the controller is moved in two directions, and the elbow lever h, with its connection with the controller n are the means by which the electromagnet and armature operate such controller. Also the link Ii connects similar portions of the operating means oftwo corresponding switch devices together, so that the electromagnet and its armature move both controllers together or at the same time. When the parts occupy the positions seen in Fig. 5 the terminals or contact springs are in operative relation to their coacting parts, as C Fig. 7 or C Fi 6, and whenever these parts C or C, whic are pivotally mounted on frames N of the switch devices, are moved on their pivots, as is the case of devices A and A, Fig. 6, then such terminals or contact springs will be brought into contact and the circuits closed. as in the case of device A, and the signals 'ven. In Fig. 6 controller 11. of switch evice A is in the position seen in Fig. 7 and hence the contact springs remain separated or open, as pair a are there seen. The controller of switch device A is in the position in which controllers n are seen in ig. 5, after elbow levers h and link It have been moved and the corresponding terminals or springs are in contact, as shown. The extent of movement of controller n and its terminals or contact springs from one position to another to bring the circuit or circuits from an inoperable to an operable condition is seen in the case of device A of Fig. 6, where the controller has been actuated, but the coactin parts C and C have not yet been actuatef. The difference in ositions between the dotted and full lines indicate the extent of this movement. The extent of this movement of the controllers, as n, may be such as is desired so that when the controllers and attached parts of the switch devices are in an inoperable condition the movement of the parts, as C and C will not cause one terminal to electrically connect with the other. As seen in Fig. 6 actuating device or carriage B is moving in the direction of the arrow and has not yet quite reached parts 0 and C, part C only being seen, and the terminals or contact springs are open and will remain 0 en until the actuating device or carriage as actuated parts 0 and C, as seen in the case of switch device A.

As here shown, when the magnets M, M, &c., are energized and the controllers are actuated, retaining devices are employed to hold or retain the controllers and their connected circuits in substantially the position shown in Fig. 5 and of devices A and A of Fig. 6. These retaining devices consist of elbow levers O ivotally mounted on frame N, as more clear y seen In Fig. 4, where such devices are in their normal ositions ready to engage with pins 0 fixed in controller n. One end of elbow lever O is hook shaped, so that as controllers n move toward the pivot of such elbow levers the spring q causes such levers, through link p, to press against the pins 0 and as soon as such controllers have moved far enough in that direction such spring causes the levers to en gage with pins 0, as seen in Fig. 5, where the two corresponding controllers are held by corresponding retaining devices connected together to act or move as one, so that-either actuating device or carriage, (the one first approaching,) can actuate both retainin devices at the same time. The springs q, q &c., normally tend to move the retaining devices into the engaging position and to re tain the controllers and circuits in position for the circuits to be closed and the signals to be given, when once brou ht into a condition or position where this can be done. As shown the frame or support N of each switch device has a retaining device pivotally attached thereto, and the retaining devices of two corresponding switch devices are connected together so that the actuating device of either one of two cars may actuate both of the retaining devices. These levers O, O, &c., are actuated against the stress of the springs q, g, &c., by projections mounted on the carriages, one projection on each carria e for up signals and one on each for own signals, and such projections engage with the elbow levers O, O, &c., and actuate them at the time it is desired that the signals shall cease, or otherwise, as one sees fit to construct the apparatus. It will thus be seen that the circuits are brought into operable condition upon energizing the magnets M, M, &c., in any well known manner, as by push button devices arranged at the desired stations, and that such circuits are restored to an inoperable condition by the actuation of the retaining devices by the projections carried by the carriages, as such carriages move past the retaining devices in accordance with the movements of their respective cars, whether there be one, two or more cars. to be served. As seen in Fig. 2 switch devices for eight stations or floors are indicated, but there are only retaining devices and controllers and switch actuating devices shown for portions of four stations or floors, the first and last up, and also the first and sixth down stations for two cars. As before explained this requires four electromagnets and means for energizing them. Magnets M. M, M and M, respectively. Magnets M M actuate the switch devices for one floor or station for two cars, one magnet. as M, actuating the up devices for that floor or station and the other magnet, as M, actuates the down devices. The means for energizing these magnets are shown located adjacent to each other at one point or place and as seen in Fig. 2, one is placed over the other somewhat as would be done in practice. Usually the push button actuating means for causing the signals to be given in the up ward direction is arranged immediately over the device for causing signals to be given in a downward direction. The means for energizing magnets M and M are laced at different points. For convenienceo illustration difl'erent sources of energy are shown, but in practice a. single source would naturally be used. Push button devices are illustrated but any form of devices may be emloyed. Push button devices P, P, P and are shown with sources of energy S, S and S. Magnet M is connected with push button P and source S by wires 66, 67 and 68. Magnet M is connected with push button P and source S by wires (39, 70, 68 and 71. Magnet M is connected with ush button P and source S by wires 72, 3 and 74 and magnet M is connected with push button P and source S by wires 75, 76 and 77.

The levers or coacting movable parts C and G are, as shown in Fig. 9, mounted on a common support or stud l), which in turn is fixedly mounted in frames N of the switch device, as shown. Lever or movable part C hasa hub c which receives a two arm spring (1 and lever or movable part C has a similar hub c, which receives a similar spring at, which springs are arranged to exert their stress in retaining and holding these levers or movable parts to the position indicated in Fig. 7. Stud or support is provided with a projection d with which spring 03 engages, one arm of the spring engaging with one portion of such pro ection and the other arm engaging with the opposite portion. This pro ection (1 permits the two arms of this spring 03 to separate or move apart from one another and the stress of the spring holds both arms in contact with projection d when force is not applied to overcome such stress. On the other or reduced end 0 of support or stud D a sleeved with a projection d similar in construction "and function as projection d is secured by nut d, which fixedly holds sleeve 0 from turning on the reduced end 0 of support D. This sleeve 0" also holds the levers or movable parts 0 and (l in place on stud or support D, leaving them free to turn thereon as occasion requires. Each lever or movable part C and C is, as shown, provided with an arm or extension C and C respectively. Each of these arms or extensions is provided with a pin or projection c and 0 respectively, which pin engages with the two arms of each of the springs d and d, respectively, as shown, Figs. 7 and 9, more particularly. Each of these levers or movable parts C and C is also preferably provided at one end with insulating material 0, Fig. 7, to contact with the adjacent terminal or contact spring and at the opposite end with a roller or wheel 0 with which the coacting portion orportions of the carriage or carriages engage to bring the terminals or contact springs into contact to close the circuit or circuits, as seen in the case of switch device A in. Fig. 6, where the parts are shown in the positions they occupy at that time. These levers or movable parts 0 and C are free to move in both directions except for the stress of the springs d and d, consequently the engaging parts carried on the carriage, if fixedly attached thereto, may move or operate them in either direction of movement. When these levers are moved in one direction the insulated end portions, as 0, move toward the contactsprings or terminals and when they move in the other direction such ends move in the opposite direction and away from such terminals and do not affect them, even when in position to be actuated by such levers.

Each carriage is mounted in grooved rollers, as b, b, 0, b, &c., so as to move over the switch devices, as indicated in Figs. 1 and 2, and in definite relation thereto and the levers or movably mounted parts, as (J and U, and to co-act therewith, as hereinafter explained. 7

Each actuating device or carriage, B, or B, as here shown, is preferably provided with parts, as E, E, to co-act with the levers, as C and C, which are movably mounted thereon, as shown, one part to coact with the levers for the up switch devices and another to co-act with the levers for the down switch devices, carriage B having parts .E and E and carriage B having parts E and E parts E and E coacting with the up switch devices and parts E and E co-acting with down switch devices. These parts, as E, E, E, &c., are preferably mounted on swinging links, as e, e, e &c., one end of each link being pivotally mounted on a support carried by the carriage and the other ends being pivotally attached to such parts, two links for each part, as shown, more particularly, in Figs. 2, 3 and 6. Links e, e, 2 &c., are connected with supports F, F, F etc, respectively, and as a result parts or portions E, E, &c., are free to swing back and forth thereon except when restrained therefrom. These swinging portions of the. actuating device or carriage mechanism are mo\ ed in one direction, that is, away from the lovers or parts C and C by springs f, 7'', &c., res )ectively, and they are moved in the other direction, that is, toward and into position to engage with the rollers, as c on the levers or movable parts 0 or C by electromagnets, L, L, L &c., armatures I, l, P, &c., and connected parts, when the magnets are energized, and such parts are held in such positions so long as such magnets remain energized, the force of the magnets overcoming the stress of springs f, f, F, &c. The armatnres Z, l, l, &c., are mounted on pivoted levers l, l, l, &c., re-

spectively, as shown, the opposite ends of which are pivotally connected with portions E, E, E, &c., respectively, so that as such armatures are attracted by the magnets the levers l, l, l, &c., turn on their fulcrums moving the parts E, E, E, &c., respectively, into the position, in which portion or part E is seen in Fig. 6, which has been moved from the position seen in Fig. 3 to that seen in Fig. 6, or from the position seen in dotted lines to that seen in full lihes in Fig. 6. As thus seen the links are substantially at right angles to the under or co-acting surface of the part E. This is the preferred manner of arranging the links, if these parts be mounted as ust described, but they may be .arranged otherwise, if desired; also the links may be dispensed with and the portions of the carriage mechanism which coact with the levers, as C or C, may be otherwise mounted to move into and out of active or coacting relations with such levers,

as, for instance, by pins and inclined slots as indicated in Fig. 6. As there shown actuating device or carriage B" 18 provided with co-acting part E" in which slots e? and e are formed which embrace pins e and 0", respectively so that as this part E is moved from the position seen in full lines to that seen in dotted lines the inclined slots acting on pins e and e move such part E away from the rollers c on movable parts C to the extent indicated by the dotted lines, when the parts or levers C move into the positions seen in dotted lines by the action of their two armed springs d. One advantage of the links is that they may be made of substantially the same length between centers as the distance from the center of the hub c of lever C to the outermost part of roller'c, and then if the part or portion E be brought into co-acting relations with levers, as C and C, while directly over the rollers, as a, such portion E will move into position with a movement substantially corresponding with the movement of the levers, as C and C, on their studs D and without undue strain upon any of the parts of the mechanism. The springs, f, f 112:, &c., always tend to move the ortions E, E, &c., out of coacting relation with levers as C and C, and are of the desired stress to do this work and hence, when the magnets L, L, L, &c., are not energized all of these portions are held by these springs in the inactive positions and remain so until the stress of the springs is overcome by a superior force. The stress of each spring in the construction shown, is overcome by energizing a magnet as L, L, &c. This is accomplished in any well known manner, but it is preferably done bv means of an automatic switch as K or K. Fig. 1, combined with circuits, &c.. so that as the carriage changes its direction of movement the uut0- matic switch changes cuttin out one magnet and cutting in anot er. switches K and K may be of any desired form and construction, so long as they operate to cut out and cut in their res tive magnets at the desired changes in t 0 direction of movement of the actuating devices or carriages with which such magnets are connected. Such switches are diagrammatically shown in Fig. 1 and as there seen, they are suitably connected by friction or otherwise with some moving part of the car actuating mechanism so that as the car reverses its direction of movement the switch is operated and stays operated until the next reversal takes lace and so on. Each switch, as indicated: arms, as k, k and Is, is, Fig. 1, which are connected together and to the moving part of the actuating mechanism by connections, as k and k. These switch arms connect with switch points, as In, k for switch K and k", k for switch K. As shown switch arm is is out of contact with switch point k and switch arm k is in contact with switch point Is. Also switch arm is is in contact withpoint k and arm k is out of contact with point la.

The magnets L, L, &c., may be energized from any desired source of suitable character. As shown in Fig. 1 they are energized from the same source that operates the signal devices. When this is done the magnets are to be suitably formed or artificial resistance is to be added to prevent undue heating under long continued use, as is well known. As shown artificial or additional resistance is employed, as R, R, &c., and each is proportioned to its respective magnet or magnets which it is to serve.

The circuits between the source S and the automatic switches and magnets and back again are as follows: A wire 1 leads from source S to arms I: and k of switch K. As

before explained switch arm 1c is in contact with point Is and the circuit proceeds from such point by wire 2 to resistance R and thence by wire 3 to magnet L on carriage B, and H in car H and thence by wire 5 to wire 6 and the other side of source S. When the automatic switch K is shifted from the position shown to one where arm k is in contact with point is and arm k is out of contact with point k the circuit is from source S by wire 1 to arm k, point In", wire 7 thence to resistance R, wire 8 to magnet L and by wire 9 to wire 4, thence to switch H in car H and from there by wires 5 and 6 to the other side of source S. From this it will be seen that the circuits for magnets L and L of carriage B pass through switch H in car H and also that such circuits pass through automatic switch K before reaching switch H.. From this it results, first, that These has two switch from thence by wire 4 to the switch only one circuit through one of the magnets is closed at a time, by the automatic switch K, the other being open, and second, that both circuits are, as shown, closed through switch H and remain closed until such switch is opened, when both circuits are gpen and neither magnet can be energized.

enee the operator in the car, by opening switch H, can prevent both magnets L and L from being energized and as a result the movable portions of the carriage mechanism, which co-act with the movable arts, as C or C, to close the switch termina 5 remain in the inactive positions, that is, out of co-acting relations with the switch devices of that carriage, and no signals will be iven and the movements of carriage B baci and forth do not atfect the apparatus in any way. If for any reason it is desired that car H be run without giving signals it is onl necessary to open switch H and leave it open until such time as the signals are to be again iven, when switch H can be closed and t e ap aratus be made to operate as before. Qt er switches may be p aced in either of wires 4 or 5 if desired, in the same manner as switch is placed, or in any other well known manner.

The circuits for magnets L and L of carriage B are as follows: from source S by wire 10 to wire 11, thence to arm k of automatic switch K and oint k, (when switch K is in the position shown,) and thence to resistance R by wire 12, thence by wire 13 to magnet L, and thence by wire 14 to switch H in car H and from thence by wire 15 to wire 6 and the other side of source S. When automatic switch K is actuated by a reversal in the direction of movement of car H and carriage B the circuit for magnet L is as follows: arm is is in connection by wire 11 with source S and point Is and a wire 16 leads from such point to resistance R, thence, by wire 17, to magnet L and thence by wire 18 to wire 14, switch H in car H and from there b wires 15 and 6 to the other side of source As before explained each station or floor is provided with two signal devices one up and one down, and, as shown in Fig. 1, these are designated as I, I, I, &c., for giving signals as the car moves upwardly and as I, I, I, &c., for giving signals as the car moves downwardly, the signals for each car being duplicates of those for each of the other cars served by the apparatus and each car and connected carriage operate only their own individual signa is.

Also each car is provided with a sin le signal device, as G, for car H, and G or car H which signal devices are operated by the movements of the car and connected carriage as the car or object reaches the desired point. station or floor where the s gnal s to be given. As shown there are eight stations or floors where signals are to be given by each car, but there may be any desired number in any given apparatus. Also each station has two switch devices assigned to it,

one for up signals and one for down signals, each device having two airs of terminals or contact sprin s by wiiich the circuits are closed. As siown in Fig. 1 only the circuits leading to switch devices of every other station or floor are shown, this being done to avoid confusion from a too great multiplicity of lines and as the circuits are all of the same kind or character, illustrating one is in substance an illustration of all of the others, to those skilled in this art. The up switch devices for one car constitute a series and for two or more cars a plurality of series. 'The up switch devices for two or more cars for any given floor or station correspond one with the other in that each serves its own car at one floor or station and does the same work and gives a similar signal when the circuit is closed. This is also the case with the down switch devices at any given floor or station served by two or more cars.

The circuit or circuits for car H are as follows: A wire 1 leads from source S and connects with wire 19, which leads to signal G in car H and from thence a wire '20 connects with wire 21, which is connected with terminal a of switch device A, and then with terminal a" of switch device A, and so on until the last pair of terminals is reached, the other terminal of each pair being in turn connected with wire 22, which connects with wire 6 and the other side of source S. As thus connected the circuit may be from source S through wires 1 and 19 to signal G and then by wires 20 and 21 to any pair of terminals connected with wires 21 and 22, through such terminals (when brought into contact,) to wire 6 and back to source S. This is for the car H and carriages B as they move upwardly; when they move downwardly the circuits are the same as when moving upwardly to the point where wire 20 connects with wire 21, which also connects with wire 23, which latter wire connects with one of each pair of terminals of switch devices A, A, &c., as wire 21 does with those of devices, A, A, &c., the opposite or other terminal of each pair con necting with wire 24. as wire 22 connects with the terminals of the up devices.

For car H the circuits are as follows: A wire 10 leads from source S and connects with wire 11, which in turn connects with wire 25 leading to signal G in car H and a wire 26 leads from there to and connects with one of the terminals of switch devices A. A. &c., (the up switch devices for car H'.) as wire 21 connected with corresponding terminals of the up devices for car H,

88 49, which connects #6 rolpondingsignals for carH were connectthe opposite or other terminal of each of such pairs being connected with a wire 27 which connects with wire 6, which in turn connects with the other side of source S. As in the case of car H the circuit or circuits for the down going signals are the same for a given distance, to the point where wire 26 connects with wire 28, which in turn connects with the terminals of switch devices A, A, &c., as wire 23 connects with corresponding terminals of corresponding switch devices for car H, the other or opposite terminals of each switch device being connected with wire 29, which in turn connects with wire 6 leading back to source S.

The circuits for the station signals forcar H are as follows: A wire 30 leads from source S and connects with each signal device at each station, that is, such wire is common to all of such devices, from signal I, (the upper one of the up signals,) a wire 31 connects with one of the pair of terminals, as a, of switch device A, the other terminal of such pair being connected by wire 32 with wire 1, which leads to the other side of source S; from signal I wire 33 connects with one of the air a, of terminals of. switch device A, e other terminal being connected by wire 34 with wire 1 and source S, as before; from signal I wire 35 connects with one of the air a'-o terminals of switch device A, t e other terminal being connected by wire 36 with wire 1 and source S; and from signal I wire 37 con- .nects with terminal a of its respective switch device A, which is seen in Fig. 2, the other terminal being connected by wire 38 with wire 1 and source S, as before. For the down signals 1, I, &c., a wire 39 connects with wire 30 leadin from source S and also connects with elf of the down signals for car H as wire 30 connects with the up signals; from signals I I, I", and 1", wires 40, 42, 44 and 46, respectively, con nect with one of the down pair of station terminals of switch devices A, A, A and A, respectively, as in the case of the up pairs, the opposite or other terminal of each pair being connected by wires 41, 43, 45 and 47, respectively with wire 48, which in turn is connected with wire 10 and source S.

The down signals for car H are all connected with source S by wire 6 and the up signals are also thus connected by wire with wire 6. The up signals I, I, I and I are connected with corresponding terminals of switch devices for car H, as corresponding signals for car H are connected, using wires 50, 52, 54 and 56, respectively, instead of wires 31, 33, 35 and 37, res tively, as in case of car H. The down signals for car H as I, I, I" and I" are connected with the terminals of switch devices A, A, A and A, as cored, using wires 59, 61, 63 and 65-, respectively, instead of wires 40, 42, 44 and 46, re spectively, as in case of car H. The respective opposite or other terminals 'of such up devices are connected with wire 27 by wires 51, 53, 55 and 57, respectively, and the respective down devices are connected with wire 10 by wires 58, 60, 62 and 64, respectivcl The operation of the apparatus, as thus shown, is as follows: Assuming that a person is on the floor or at the station where push button devices P and P, Fig. 2, are located and desires to go upwardly therefrom, (it being understood that there may be as many. stations or floors above and below those shown in Figs. 1- and 2, as one desires,) he would press the push button P, energize magnet M move the controllers of switch devices A, A, into position where retaining devices 0, 0, would engage therewith and retain such controllers and the terminals of the circuits mounted on such controllers in position until actuating device or carriage B had reached switch device A with whichthat carriage co-acts when si nal I, located at that station and signal in car H for that car would be operated and the signals, in themovement of the carriage, would be given at both places, and continue until projection e on portion E of carriage B, Figs. 2 and 4, reaches retaining device 0 when the outer end, b the continued movement of carriage will be moved downwardly and its hooked end, in engagement with pin a, will be moved out of engagement therewith and by reason of link p the corresponding retaining device for switch device A of the other car B, will be correspondingly moved and the controllers of both switch devices A, A, will be free to move under the stress of their springs n and the terminals of both switch devices be moved awa from co-acting relations with portions and E of carriages B and B and the signals I and G will cease to be operated and the circuits connected with such switch devices will be restored to an inoperable condition, until push button be again actuated, when the operation may be repeated. The operation of each of the other stations is a repetition of the above, there being separate up and down 'push button devices to be actuated for each of the stations or floors where persons are to go both up and down, as is well understood in the art.

It is to be observed that by reason of the springs a, g, &c., the retaining devices are ever ready to engage with pins 0, o, &c., 'of the controllers n and, therefore, just as soon as the armature of any of the mag nets as M, M, &c., has been fully attracted the retaining devices for the controllers connected with such armature engage therewith and retain them in position permittin such magnet to be denergized without anger of the controllers and terminals returning to the positions from which they were moved upon the energizetion of such ma net. Hence a momentary ener zation of t e magnets, as M, M, &c., is al that is required to brin the circuits from an inoperable to an opera le condition, and when once brought into an operable condition the remain in this state until the retaining evices are operated by the movement of the carriage or carriages.

If for any reason it should be desirable for the movable co-acting part, as E, of the carriage or actuating device B to move on its links and away from the levers or movable parts, as C and C, as for instance on the sudden reverse movement of the carriage and before the automatic switch had reversed and cut out the magnet L a yielding connection between such part E and the lever l to which armature l is secured may be made, as shown in Fig. 10. As here shown actuating device or carriage B carries the movable co-acting portion or part E by means such as shown in Figs. 2, 3 and 6. The carriage B is also provided with a magnet L, armature Z, pivoted lever l, to which armature l" is attached and spring f by which the lever is moved to move the armature away from its magnet L. The stress of this spring f is of course overcome by the action of the magnet upon its armature. Pivoted lever l" is made in two parts I and Z. This part Z of lever Z" is in the form of a flat spring secured to lever portion l at one end, as shown, so that upon the application of force to coacting part E in a direction tending to move it from the position seen in Fig. 10 in full lines to that seen in dotted lines this springy portion 1" will yield and permit part and the pin 1" fixed thereto-to move and swing on its links in the opposite direction to that in which it swings under the stress of spring f when magnet L is deenergized and in so doing to move away from the levers or movable parts, as C and C, and then when the force thus applied is released or the magnet L is deenergized the parts of lever Z assume the positions shown in full lines.

Instead of the construction of movable parts, switch devices, controllers and retainlng devices seen in the preceding figures a construction like that seen in Figs. 11 to 15 may be employed, wherein each controller is shown in the form of a bar, sliding horizontally and, if desired, supporting switch devices for a plurality of actuating devices or carriages to co-act with: also wherein such controllers are retained or held in the positions which renders the circuits connected therewith inoperable and the controllers are spring actuated into position to bring the circuits into operable condition and are yieldingly held there by the stress of the springs which actuate them. In the construction shown in these latter figures, as in that seen in the preceding ones, the parts which bring the terminals of the switch devices into contact to close the circuits are movably mounted on supports and they may always be in position to be actuated by the movements of their respective carriages. In both constructions these movable parts are preferably held in position to be actuated in either of two directions, as the carriage moves into engagements therewith, and this is preferably done by means of two arm springs, as shown. In the construction s own in these Figs. 11 to 15 two bars or controllers may be employed for each station or floor. Controllers, switch devices, movable parts, &c., are shown in Fig. 11 for two of such stations or floors and somewhat widely separated from one another. In practice the space between these two sets of devices, one set for each station or floor, would be occupied by similar sets of devices, which are here omitted for clearness of illustration. Also as many similar sets of devices may be arranged above and below those shown as the constructor sees fit to employ to serve any desired number of stations or floors. Also as shown the ap aratus is arranged to serve two cars, each 0 which is provided with a signal device, which are the only signals the apparatus, as shown, is designed to give. If desired signals located at the stations or floors may be employed, as illustrated in Figs. 1 to 10, inclusive, and also in Fig. 15, which illustrates two movable parts mounted on a fixed support or stud co-acting with two pairs of terminals, one pair for each of two circuits.

As shown there are eight switch devices A20 A21, A22 x23 A24, A25, A26 d A21 t of each being mounted on each of the sliding bars or controllers, U, U, U and U",-as for instance, switch devices A and A" are mounted on bar or controller U, devices A and A on controller U, and so on. These controllers are mounted in'bars Y, Y which are secured to frame F of the apparatus. As only one signal device is to be operated in each car, each switch device is provided with but one pair of terminals, as a, a, a, a, a, a, a" and a", respectively, as soon. To co-act with each pair of terminals and close the same, there is a movably mounted lever or part, as V, V, V, V, &c., each lever being preferably provided with insulating material at its co-acting end. as 1', 1", r. W, &c., and is mounted on a stud or support, as a, w, v, a", &c., respectively, which studs or supports are, as shown, in turn mounted fixedly in bars U, U, l and U, studs '0 and t" being mounted in bar [I studs 1) and 'v in bar U, studs '0, and o in bar U and studs '0 and o in bar U.

There are two carria es, B and B,

mounted to move back an forth in front of 5 sliding bars or controllers, as U, U, &c., in co-act1ng relations with movably mounted levers or parts, as V, V, &c., which may be connected with the car actuating mechanisms as carria es B and B are shown to be connected or ot erwise, as desired.

The car with which actuating device or carriage B ma connect is diagrammatically re resen at H and is provided with signal evice G, and the car with which 5 actuating device or carriage B ma connect is likewise represented at H an is provided with signal device G. Carriage B, through surface E, co-acts with movably mounted parts or levers V and V, as it moves upwardly and throu h surface E, with levers or parts V and as it moves downwardly, and carriage B, throu h surface E", co-acts with levers or parts and V, as itmoves upwardly, and, throu h sur- 215 face E", co-acts with levers or arts and V, as it moves downwardly. ach of these levers or parts, as V, V, &c., is preferably provided with a two arm spring as d, Fi 13 and d", Fig. 12 of the drawings, whic 80 act on said levers or parts as springs d and of Figs. 7 and 9 act, a projection or pin, as 0, Fig. 13 on each of the levers and a fixed stud or projection, as d, attached to bar U, Fig. 12, coacting therewith, as 001'- 85 responding projections c and d coact with 'sprmgdin igs.7and9. I,

As shown in Figs. 11 and 12 surface E, of carriage B has after coacting with movably mounted part or lever V and cl 40 terminals a" of switch device A", 25 entirely by such lever so as to permit its two arm spring d" to act and return'the lever to its normal position thereby o terminals a" again, and incline sur ace X,

(mounted on carriage B) has engaged with surface or roller 0: attached to controller U, moving it against the stress of spring u until stop u" v on armature m has enga with rojection u attached to contro er U. be controller U when in this position retains or holds the switch devices A" an A" in position so that the movable levers or parts V and V do not close the terminals of their respective switch devices until such devices and their circuits are brought into an o erable condition again by the person desiring to signal the car using the means provided for this purpose. Carriage B has mounted thereon two movable inclined abutting surfaces X and X and carriage B has two similarly mounted surfaces X and X. These surfaces are held against turning in one direction by pins {351' and 3 respectively and are norma y el in contact with such pins by springs 31, y, y and 3 respectively, which yield and rmit these inclined surfaces to assume ositions corresponding to that in which sur ace X, of carriage B,

is shown in, when passin roller or surface :0 on controller U, while t e carriage is moving downwardly and such controller is in position for its switch devices to be operated as either actuating device or carriage is moving upwardly, as'shown. Surface E of carriage B in moving downwardl has engaged with movable lever or part a and closed the pair of terminals a and thereby closed the circuit to operate the singal G in car H, and such surface will hold such circuit closed so long as it is in contact therewith, as shown. When surface E has left or is just leaving lever or movable part V inclined surface X engages with roller or surface 2 attached to controller U and moves it against the stress of spring, not shown, until it is in the position controller U is seen to occupy in Fig. 11, where armature m of magnet M" has engaged therewith, so as to retain the controller in position where the circuits connected therewith will be" in an inoperable condition, until armature m" is attracted by energizing magnet M. This may be done by any convenient means such for instance, as a source of energy, as S, push button P and circuit wires 103, 104 and 105. All of the other magnets M", M and M are shown as being similarly energized. Magnet M" is connected with source S and push button P" by wires 100, 101 and 102. Magnets M" and M are connected with source S and push button P and P", res ectively, by Wires 106, 107, 108, 109, 110 an 111, respectively, as shown. Signal device G is connected with switch devices A and A" to give signals as carriage B moves upwardly and with devices A" and A" to 've signals as the carriage moves downwar ly. Signal device G is connected with switch devices A and A to give signals as carriage B moves upwardly and with devices A and A to give signals as it moves downwardly. Only one signal device is em loyed in each car for giving the up an down signals, the signals being given as the car approaches the floors or stations, in both directions of movement thereof.

The circuit for signal device G is from source S' by wire 112, thence by wire 113 to one terminal of each of the up switch devices A and A" and thence by the other terminal of each of these devices and wire 115 to the other side of source S, for the up signals; and for the down signals the circult is from S by wire 112 to signal device G thence by wire 113 to wire 114 and one terminal of the down switch A and thence by the other terminal of such device and wire 115 to the other side of source S and also from wire 118 to wire 122 and then 30 to one terminal of device A and thence by the other terminal wire 123 and to wire and source S".

The circuit for signal device G is from source S by wire 116 to such device, thence by wire 117 to one terminal of the switch device A and thence by the other terminal of such device and wire 118 to the other side of source S and also from such device Gr by wires 11? and 119 to one terminal of switch device A and by the other terminal of that switch device and wire 120 to wire 118 and the other side of source 5*. These are the circuits for the up signals for car H and for the down signals of this car the circuits are by Wires 116, 117 and 119 to one terminal of each of the switch devices A and A, thence by the other terminal of such switch device and wire 118 to the other side of source S.

In the operation of giving the signal, when the carriage is moving downwardly, as indicated in Fig. 11, (where carriage B is thus shown,) the magnet M is energized by operating push button P releasing controller U from the holding action of armature m. and permitting the stress of spring, not shown, to move such controller into the position shown, bringing the switch devices A and A, controlled thereby, into an operable condition. Then on the downward movement of carriage B the coacting portion E, thereof engages with the adjacent end of the lever or movable part V moving it on its pivot or stud '0 bringing its opposite end, having insulating material 1' into contact with the nearest one of the pair of terminals a, closing the circuit therethroagh and causing signal device G to operate and to continue in operation as long as this coacting portion or part E of carriage B holds lever V in the position shown in Fig. 11. and portion E have reached the point where such portion ends, then'or about then the inclined surface X mounted on this carriage, will enga ewith roller :0 mounted on controller F] and, as the carriage continues its downward movement, the inciined surface X will force the controller U against the stress of spring u, not shown, and restore the switch devices and the circuits connected therewith to an inoperable condition, in which they will remain until push button P is again operated. This operation is repeated for each signal to be given from the station or floor where magnet 11 is situated. and the same is energized. If an up signal is to be given at this same station or floor then push button P will be energized and controller U and switch devices A and A will be moved into operable position and the above operation in substance will be repeated, the carriage moving upwardly instead of downlVhen the carriage B" wardly. The operation of the parts connected with each magnet and its push button is substantially the same. The signal is given in the first approaching car and the parts are restored to position by the continued movement of the carriage, whether such carriage is moving upwardly or downwardly, accordingly as the up or down devices are brought into operable condition by operating their respective push buttons.

If desired the controllers, as U, U, &c., may be made to support or carry only one terminal of the circuit with which each switch device is connected, as indicated in Fig. 14, where a portion of a controller, U is shown to which is attached one terminal t of a switch device A. The other terminal If is fixed to the bar U to which the lever or movable part V is pivotally attached and consequently this lever and the terminal 6" of the air of terminals (4 do not move as the controller moves in bringing the circuits into an operable condition and restoring them to an inoperable condition. A spring a is connected with controller U and the bar Y, so as to operate in connection with the armature m as spring a operates with armature m? of Figs. 11 and 12. 'hen controller U is released by the movement of armature m the terminal t of switch devices A is moved toward the right under the terminal t and then when lever or movable part V is actuated by the upward movementof a carriage, as 13, having a coacting portion or part, as E, engaging therewith germinul It will be moved downwardly and the circuit closed by the contact of terminals 15 and t, and such circuit will remain closed until controller U 8 is restored to the position seen in Fig. 11. \Vhen this movable part or' lever V isnnoved by the upward movement of its coacting portion of the carriage asll", with the parts as shown in F ig. 1-1, the extent of movement of such lever will not cause terminal t to touch terminal t consequently the circuit remains in an in operable condition until armature -m is operated.

Instead of using only a; single movable part or lever mounted on a fixed support, as shown in Figs. 11 and l2,two such levers or movable parts may be so mounted, as shown in Fig. 15, where a section of a controller, as U, is provided with a switch device A" having two )airs of terminals a and a". Two levers i and V similar to those seen in Figs. 11, 12 and 13,-are pivotally mounted on a. stud a which is, as there shown, fixedly attached to bar U. These levers or movable parts V and V are provided with two arm springs 61*" and (1, respectively, which are arranged in,con nection with pins it. (1. (1 and d", similar to pins J and d of Fig. '13, soas to llO operate as the corresponding levers or movable parts operate in Figs. 11, 12 and 13.

I have herein shown and described movable parts mounted on supports which are separate from that which supports the switch devices, or the movable portions thereof. The essential thing, so far as concerns the mounting of these parts, is that each shall be so mounted that a movement may take place between such part and some portion of its switch device, whereby the operative relations between the two may be changed accordingly as the switch device or devices are to be operated or not. The mountings of these niovablc parts herein shown will naturally suggest others, to the minds of those skilled in the art, which will serve the same purposes in the same way that those shown do in the combinations of devices or members hercin particularly pointed out, and, therefore, I desire that it be understood that this invention is not limited to any specific form or c nstruction of movable parts or of their mountings or supports, but desire to include all that perform essentially the same work in substantially the same manner in su h eoinbinations'as these do which are herein shown. I have also shown and described different forms or constructions of actuating devices or means, having both movable and immovable portions, which engage with such movable parts, as such devices or means more relatively thereto, and actuate the same. here the engaging port ons of such dcvicrs or means are movable in and out of operative position relatively to such movably mounted parts and means are i provided by which such portions may be thus moved or permitt d to move, such portion or portions and means may be of any desired form or construction, so long as the pa t, device or thing may be substituted for another and do the same work in any particular combination thereinafter pointed out in essentially the same manner that the part, device or member hercin shown and deibed docsits work. This isalso the case with the switch or contact devices, whether provided with movable parts or'portions or not. also with the controllers, terminals, retaining devices. or the means by which the n iovablv part; of the switch and retaining devices mar be moved from one position to another in the operation of the apparatus.

The Form or construction of these several parts. members. means or devices herein shown will sugge t oll c forms or construe liens to those skilled in the art. and, therefore, l wish to be understood as including all terms roiislructiinis of equivalent character to that which is specified in any given claim.

Different embodiments of the present in- VPfillCn ere herein shown and described,

wh rein different constructions of circuits,

switch devices, retaining or holding means and restoring means are to be found, in each of'which there is disclosed combinations of devices or members in a signal system or apparatus having features common to all of the others. In each construction shown and described the circuits are normally in an inoperable condition and they are brought into an operable condition by the movement of a part or member, which is held or retained for the desired length of time, or during a desired extent of movement of another part or parts and is then moved more or less to restore such circuits to an inoperable condition.

What is herein shown and described will naturally suggest to the minds of those skilled in the art to which this invention pertains other constructions of parts and embodiments of the present invention by which equivalent means combined in substantially the same manner and having the same mode of operation will accomplish equivalent work, and, hence, I wish to be understood as including within the present invention all such constructions or embodiments, and do not wish to be limited to the specific constructions herein shown.
