T0 all cti/10m it may concern.'

Be it known that I, HENRY F. NEWBURY, a citizen of the United States, residing in the borough of Brooklyn, ity ofl New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Signal Apparatus, of which the following is a full, clear, and exact ydescription, reference being had to the drawings accompanying and forming a part of the same.

This invention relates generally to signal apparatus in which a person at a given point or station can cause a portion, 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 efiicient as compared with prior devices, and one of the other objects is to improve generally the principles of operation of the system and parts thereof.

The invention consists in the combinations of parts, members or devices hereinafter set forth and particularly pointed out in the claims, which form a portion of this specification.

Like letters of reference, wherever they occur, indicate corresponding parts in all of the figures of the drawings.

Figure l shows diagrammatically and partly in front elevation one embodiment of the present invention, only a portion of the apparatus for two stations or floors being shown, the same being arranged for signals in a car or similar place and at each of the stations or floors. As shown the upper of the two sets of devices is arranged to give signals, when such portion is in operable condition, as a car or similar' object moves upwardly, and the other portion is likewise arranged to give signals as such car or object moves downwardly. Fig. 2 illustrates partly in section and partlv in plan that which is shown in Fig. 1 on line 2 2 thereof, with the switch devices in operable condition or positions` but with the switch devices arranged as it is preferred to arrange them in practice. that is. one of them directly in front of the other, so far as the terminals, retaining devices and moving parts are concerned. Fig. 3 illustrates portions of some and the whole of others of the parts seen in Fig. 2, but with the switch devices in their normal or inoperative condition or positions, that is, where such devices are not operable to close the circuit or circuits by the means provided for that purpose. Fig. et illustrates a switch device before any portion of it has been operated to close a circuit through the terminals shown. Fig. 5 shows the same parts, but after the circuit has been closed and the holding means have been operated to hold or retain the circuit closed and the means which coacted with the switch device to close the circuit has moved out of coacting relation therewith. Fig. 6 illustrates two of the switch devices, as seen in Figs. 2 and 3, one of which has been operated to close its circuit or circuits by its coacting means and the other has not been thus operated, the parts being shown when in the positions seen at the lower right hand corner of F ig. l, but turned so as to show in Fig. 6 the opposite sides of the parts seen in Fig. 1, the corresponding parts being arranged in the preferred way. Fig. 7 illustrates in end view the parts of the switch devices seen in Figs. 2 and 3 as when looking toward the left and nothing is in front of them and when one has been operated as seen in Fig. 6. Figs. 8, 9 and 10 illustrate detached parts seen in preceding figures. Figs 11 and 12 illustrate in front and edge view, respectivelv. the coacting means for actuating two switch devices. when the same are arranged in the preferred manner. instead of diagrammaticallv, as seen in Fig. 1, where the corresponding parts are shown set back from one another to better illustra te the construction of the parts. Fig. 13 illustrates a modified arrangement of the parts seen in Fig. 2, and where there is a single switch device mounted to move in two directions instead of two as shown in preceding figures and a part, substantially as shown in Fig. 9. is used solelv for the purpose of moving the switch device in one direction, that is, from the operable condition or position to the normal or inoperable one, instead of doing this work and in addition closing a circuit or circuits` as in Figs. 1 to 8, inclusive. Fig. 14 illustrates in edge view the actuating means for actuating the switch device and for moving such device romthe operable into the inoperable condition. Fig. 15 illustrates in plan view the parts seen in Fig. 13. Fig. 16 illustrates some oi the parts seen in Figs. 13 and 15 when partially operated. Fig. 17 illustrates the same parts when the actuating means moves in the opposite direction to that in which it is assumed to be moving in Fig. 16. Fig. 18 illustrates the parts seen in Figs. 13 and 15 in end view when looking from right to left and the actuating means are omitted. Fig. 19v shows in front elevation, with the controller partly broken away, a modiiied form of switch devices and means of actuating the same and of moving the switch devices 'from the operative to inoperative or normal condition. Fig. 20 shows in plan view some of the same parts that are seen in Fig. 19. Fig. 21 shows in Jfront elevation some ot the parts seen in Fig. 19, but in different positions as when being operated. Fig. 22 shows in front elevation another form of Switch device where only one of the terminals is mounted on the controller.

In the construction shown in Figs. 1 to 12 inclusive, two switch devices are employed which are largely duplicates of one another, one of which closes the circuit for a signal device in the car and the other to close the circuit for the signal device at the floor or station, as the car is moving in one direction. These switch devices are shown in Fig. 1 as arranged diagrammatically, that is not directly in front of one another, as they naturally would beV arranged'in practice. This is done to more clearly indicate the two switch devices and to distinguish one from the other. This necessitates the placing of the actuating means correspondingly one not fully overlapping the other as seen. In Figs. 2 to 12, inclusive, where two switch devices are shown, here one is directly in front of the other, as they would preferably be placed in practice to engage with the movable parts of the switch devices. Also as shown in Fig. 1 two pairs or pluralities of these switch devices are mounted on a movable bar or controller, one pair to be actuated by one actuating device, as one'car moves in one direc,- tion, and the other pair to be actuated by another and separate but similar actuating device, as another car moves in the same direction. As seen in Fig. 1 there are only two of these sliding bars or controllers, one, (the lower one of the two,) for use as the cars move downwardly and the other for use as the same cars move upwardly, and these two controllers are somewhat widely separated from one another. 1t is designed where several adjacent floors or stations are to be served by the signal apparatus that two of these controllers or bars are to be'used for each loor or station served, except the first and last ones where onemay be made use of,

if desired. These controllers and switch devices shown in this Fig. 1 are arranged Jfar enough apart to have pairs ofthese controllers arranged within the space between the two shown. These controllers may be arranged any desired distance apart, but it is preferred that they be arranged in a somewhat narrow or confined space, as for instance, each pair within a space in one direction, say one and one hali'i' or two inches for each twelve feet of movement or travel of the elevator car or similar object. rlhus, if there is a distance of twelve feet between the iioors of a building the controllers may for each fioor occupy two inches in the-direction that the actuating means travel past the switch devices, or each pair of controllers may occupy that space, or one of one and one half, or two and one haliI inches space, as the constructor sees fit to construct the apparatus.

rEhe actuating means, one for each elevator car or similar object to be served, are preferably connected with the car operating mechanism by suitable speed reducing means of any desired construction in any well known manner, as, for instance, mechanical indicators are many times connected, so as to move a certain distance while the car is moving another certain distance. As the use of these speed reducing devices and the manner of using them are so well known they are not represented in the drawings, it being understood that some form of means be employed connecting with each of the carriages or actuating mea-ns C and C shown in the drawings. The several combinations of members or devices herein set forth necessarily have the same mode of operation whether the carriage or carriages are moved by one kind ot means or another, or are moved by the hand of a person, using a rope and pulley, or otherwise.

rlwo cars, A and A', are diagrammatically indicated by inclosedV rectangular spaces near the top of Fig. 1, in each of which a signal device, as Gr, or G', is likewise indicated by a circle. These signal devices are cach operable as the car in which it is placed moves in either of two directions, and the construction and arrangement of the parts are such that the device is operated and the signal given as the car approaches the floor or station, whether it is moving in one or the other direction. Carriages C and C, as here shown, are practically duplicates of each other and each is mounted to move independently of the other, there being as many of these carriages as there are elevator cars, or other objects, to be served by any given system or apparatus. As shown, the carriages C and C are mounted to move relatively to the controllers and switch devices in suitable rollers, as f, f, f2, f3, &c., properly 'mounted in the frame F, three pairs of these rollers being seen in connection with each carriage. It is preferred that when rollers are used, as shown, that each carriage shall be within the grasp or control of at least two pairs of such rollers, so that the carriage shall be properly guided and held at all times. As here shown, each switch device, as B, B', B2, and B3, consists of a pair of terminals, as o', .722 and b3, connecting with a circuit, which is closed when the two terminals are in contact, a movable part adapted to bring such terminals into contact, an actuating part adapted to move the movable part in one direction and to engage with actuating means mounted to move past the switch device and means adapted to hold the circuit closed after the terminals are brought into contact by the movement of the actuating means. As thus shown, the actuating parts, as a, a", a2, and a3, Fig. l, are actuated by engaging with portions c, c', c2, and c3 of the carriages or actuating means C and C', respectively, and part-s, as a4,- c, a6 and 0.7, are actuated by engaging with portions of the carriages or means as c4, c5, c6 and c7, respectively. The portions or parts of the carriages or actuating means, c, c', c2 and c3, are practically duplicates of one another, and this is also the case with the portions or parts c4, c5, cG and c7, half ot each of such portions being for use as the carriages move in one direction and the other half for use as such carriages move in the other direction. As seen in Fig. l the actuating and movable parts of the switch devices nearest the controllers are the larger or longer than those which are farther away from the controllers. The actuating parts a, a', a2 and a3, when moved in one direction by engaging with actuating means C or C', actuate the movable parts e, c', e2 and e3, respectively, and actuating parts a, a5, a6 and ci, likewise actuate movable parts e4, e5, e and e", respectively. The movable parts and actuating parts of each pair of switch de v'ices, as B and B', are mounted on a single stud, so as to turn thereon, and each individual switch device is provided with a retaining device to retain or hold the circuit closed, after the actuating and movable parts of that switch have been moved suiiiciently for the retaining device shown to enga ge with the movable part thereof and prevent the spring action of the pair of terminals of that device from moving such movable part. The studs, upon which the movable and actuating parts of each pair of switch devices are mounted are in turn mounted in the controllers, D and D'. The stud l is shown as mounted in the left hand portion of controller D, and it receives the movable and actuating parts of switch devices B and B', the stud d2, mounted in the same controller, receives the movable and actuating parts of switch devices B* and B5; stud d', mounted in the left hand portion of controller D', receives the movable and actuating parts or" switch devices B2 and B3, and stud d3 mounted in the saine controller, receives corresponding parts of switch devices B ant BT.

As thus shown in Figs. l to 12, inclusive, retaining devices I, I', l2, tbc., respectively, coact with the movable parts of switch devices B, B', B2, &c., respectively, retaining device I' being seen in position, to retain or hold the terminals of switch device B' closed, irrespective of the movements of the controller and actuating part e* of that switch device, until such retaining device has been moved out of retaining position by engaging with a part carried by the carriage or actuating means C mounted to move relatively to such switch and retaining devices. As shown in Fig. l switch device B' has been operated and the terminals b are closed, while switch device B has not been operated, and will not be until the portion c of the carriage or actuating means C has engaged with actuating part a and moved it :tar enough to bring the terminals of that device into contact. Controllers D and D' are 1n vable in bars Y and Y' suitably mounted on the frame F to receive them, as shown, and permit the controllers to move baclt and forth therein, so as to render the switch devices operable or inoperable, accordingly as the controller is moved in one direction or the other. These controllers, as shown, are moved in the direction to bring the switch devices into operable condition or position by suitable springs whose tension or stress always or continuously tend to move the controllers in this direction. These controllers are moved against the stress or tension of such springs by the actuating means coacting with the actuating parts attached to the controllers. Controller l) is moved in the direction to bring the switch devices mounted thereon into operative condition or position by spring E, and controller D' is similarly moved by spring E'. Controller D is held or maintained in the inoperable condition or position by a projection on armature m of electromagnet M, and controller D' is similarly held by a similar projection on armature m' of magnet M'. These controllers are released from the holding action of these armatures, as m and m' by energizing the electromagnets, as M and M', respectively.

The switch devices diagrammatically shown in Fig. 1 are seen in Figs. 2 to 12 arranged one directly in front of the other. As here shown the movable parts and also the actuating parts are of substantially the same size, as illustrated in Figs. 8, 0 and 1.0. One pair, B and B', of these switches is seen :in Figs. 2f and 3,.thesame being shown with-parts in different positions in the two gures.V lAnother pair of the same is shown in Fig. 6, (with one of the retaining devices partly in section,) turned one half over,.so as to bring `the devices in front of the controller to which they are attached. The same-devices are seen inend view in Fig. 7, as when looking from left to right. The

pair Vthus-shown consists of switch devices B6 and B7, seen in Fig. 1, and the terminals 57 of device B7 yare seen closed, while the terminals b of device BG are open.

InFig. 2 switch devices B and B are seen with the parts in the positions they occupy, when the controller is moved, as shownl in Fig. l, that is, when the switch devices, or portions of them, are in position to be operated and close the circuits connected therewith, or in operable condition. Controller D and these same switch devices are shown in Fig.- 3 in-the other, or their normal, positions or condition, that is, when the. controller has been moved against the stress of spring E by the action of the carriage or actuating means upon the switch devices, and projection m2 on armature m of magnet M has engaged with pin or projection g on controller D, so as to maintain or hold the controller against the stress of its spring and keep the switch devices in an inoperable, or their normal condition. When niagnet M is energized armature m is brought into the position seen in Fig. 2 and the stress of spring E moves the controller, and the switch device or devices carried thereby, into the position there seen. A spring, as m4, moves the armature m from the position seen in Fig. 2 to that seen in Fig. 3 when the controller is actuated into the position therein shown. `From this it will be seen that the switch devices, which are movable, are moved into and held in coacting relations to the carriage or actuating means, and when the circuits are closed the retaining devices hold or retain them closed withoutregard to the movement of the controller on which the switch devices are mounted. It will also be seen that the teeth on the actuating parts, as a and a4 will naturally enter into mesh with the teeth of the portions c and c4 of the actuating means carried by the carriage C when such portions are opposite the line of movement of the switch devices, as such devices and controller D are movedl under the stress of the spring E, whether the carriage is moving in one or the other direction. This spring constantly tends to move the controller and switch devices into operable position or condition, when once the controller is released from the holding action of the armature fm.

The controllers and the'switch devices, as shown, are movable into their normal positions or condition by one ofthe actuating parts of each pair ofswitch devices, when the parts are constructed, as seen in Figs. 1 to l2, inclusive, such one of these parts serving Ytwo functions, instead of a single one. The actuating parts, as a4, a5, a6 and a?, are preferably provided with but a few teeth, two being shown,) and the same are arranged concentric with its axis of rotation, as seen in Fig. l0, and such parts simply rotate uponpengaging with the rack teeth on the portion of the carriage which co-act therewith to close the circuit, and hence do not have any substantial tendency to move the controllers against the stress of their springs. As such parts rotate they engage with their coacting movable partsA and cause them to move with them, when the actuating parts are moved in a direction to close the circuits. Each of these actuating parts may be provided with a stud or projection, as s4, S5, s6 and sT, respectively, as seen in Fig. 6, and, as indicated in dotted lines, in Fig. l0. These pins or projections are in position to engage with the small end of the movable parts e4, e5, e6 and e7, respectively, as indicated in Fig. 6, where actuating parta7 has been rotated, engaging with the small end of movable part e7 and in turn rotating the same and closing the circuit by the contact of the pair of terminals o7 of switch B7. Each of vthe movable parts is provided with a pin or projection, as t, &c., preferably insulated from such part, to engage with one of each pair of terminals, as seen in Figs. 4 and 5. As shown in Fig. 6 the movable part e7 is in engagement with the portion 2" of retaining device I7 and will be held in the position seen until the part jT of such retaining device is acted upon by the p0rtion J7, Fig. l, carried by the carriage. Each retaining device as I, I, I2, &c., is preferably forced tow-ard its movable part, as e, e, e2, &c., by a suitable spring or springs, so as to move relatively thereto, as shown in Figs. 3 and 5. One of these springs, as Z, is seen in Fig. 5, and each operates in the same way, as there shown, the stress of such springs tending to move the retaining devices toward their respective movable parts, as indicated in this Fig. 5.

The actuating parts, as a, a', a2 and a3, as before explained, serve two functions, one of which is to actuate or operate their respective movable parts by engaging therewith, as in the case of parts a4, a5, a and a7 which engage with their respective movable parts e4, e5, e and e7, and the other one is to move the controllers on which such parts a, a, a2 and a3 are mounted from the position where the switches are in operable condition into an inoperable, or their normalcondition. Instead of only a few teeth, as

for instance two, as shown inthe case of.

actuating parts a4, a5, &c., a greater number are preferably employed, as for instance five, as shown, on each part, as a, a', &c.; and also instead of these teeth being arranged concentric with the axis of rotation, as in the case of parts a, a5, &c., they are preferably arranged eccentric thereto so as such parts rotate they have a cam action and force the studs on which they turn away from the path of movement of the carriages or actuating means to the extent of their eccentricity, the controllers in which the studs are mounted moving with such studs. In this way the. controllers are moved against the stress of their springs, as E and E, until they have reached a point where their respective armatures will engage therewith and maintain them in their normal positions, where the switch devices carried thereby are inoperable by the actuating means, as they move back and forth past them. The extent of the eccentricity of these actuating parts, as a, a', &c., may be such as is desired by any individual constructor, so long as it serves to move the parts to the desired extent. The number of teeth employed on any of the above actuating parts may be such as is desired, such as a single one, as shown in Figs. 13 to 18, or more, and the shape and construction of the same, as well as that of the several parts, may be such as is desired, so long as the general mode of operation be substantially the same as herein set forth.

If desired a partial tooth may be used, as shown in Fig. 9 and elsewhere, on each of the actuating parts, as a, a', &c., so as to gradually increase the eccentricity of such parts and move the controllers against the stress of the springs, as E and E. These actuating parts a, av, a2, a3, at, a5, &c., are preferably held in a given position, so that they will engage with the actuating means with which they coact to close the circuits, before reaching their axis of rotation, as shown, and thus move past such axis to ciose the circuits. The positions actuating parts a3 and a7 occupy in Fig. 6 has been found in practice to be a satisfactory one for the engagement of these devices with the portions or racks c, c, c2, c3, c4, &c., whether the controllers and switches mounted thereon moved from their normal or inoperative positions to the operative one before the actuating portions c, c', c2, c3, c4,&c.,had reached the switches, or as such portions were passing by them, in their movements relatively thereto. These actuating parts a, a', a2, a3,

ut, &c., are shown as being held in their given positions by two arm springs, as r, r", 772, r3, r4, &c., respectively. These springs are coiled around hubs on the actuating parts and one arm of each spring extends on one side of a pin or projection, lc, lc', k2, la, c, &c., on the actuating part and a pin or projection, as u, u', u2, &c., mounted on the controller, and the other arm of each spring extends along the opposite sides of the same pins or projections, as seen in Figs. l to 7. As here shown a single pin or projection, as u, u, u?, &c., mounted on the controller serves for the actuating parts of a pair of switch devices, as seen in Fig. 7. As soon as the actuating means, as c, c', &c., engage with the actuating parts, as a, a', ai, &c., they overcome the stress of these springs, as 7', 7", r2, &c., and such parts are permitted to move until such means have operated suoli parts to the fuli extent and as such means leave, or disengage from, such parts these springs immediately return the actuating parts, as a, a, &c., to their normai or given positions, as seen in Fig. G, whether the movable part is detained or not. These two arm springs also permit the actuating parts, as a, cz, &c., to move in the opposite direction and to then return such parts to their normal or given positions again. From this it will be seen that these actuating parts are yieldingly held in a given direction by a single spring' and each is movable in two directions upon the application of force thereto suiiicient to overcome the stress of such spring.

The retaining devices, as I, I, I2, &c., are moved against the stress of their springs, as Z, Z, Z2, &c., by inclined or abutting surfaces, J, J, J2, J3, J, &c., mounted on the carriages and arranged to abut against the ends j, y", 7"2, ji, j, &c., of the retaining devices I, I, I2, &c., and move such devices, as retaining device IT is moved by abutting surface J T, in Fig. l, and thereby release the movable part ci, as there seen, opening the terminals of and the circuit connected therewith. As seen the switch device B7 has its terminals closed, and they will remain closed until abutting surface J G reaches the end j of retaining device IT in the continued downward movement of carriage C and forces it backward to the extent retaining device I@ has been moved back bv abutment J 7. As soon as the retainin0r devices have been forced backwardly againsfthe stress of their springs by the abutments, as J, J &c. the spring action of the pairs of terminals, as b, Zi, &c., will return the movable parts, as e, e, c2, &c., to their normal positions, as seen in Figs. 3 and i, and as such abutments move past and out of engagement with the retaining devices they engage with the rear circular ends of such movable parts, except as they are moved out of engagement therewith by the passage of the abutments by them or the movement of the movable parts out of engagement therewith. These rear` ends of the movable parts may be given any desired shape. The form shown has been found to answer the purpose very well.

The controllers are released by energizing lthe magnets, as M, M', and withdrawing the projections, as mi, m3, on armatures, as m and m', out of engagement with pins or projections, as g and g, on controllers, as D and D', and permitting such controllers to move under the stress of their springs` as E and E. These magnets, as M and M, and their armatures, &c., form a portion of the means by which the controllers and switch devices are released, and such portions are preferably located at a given place or central station. The other portions of such means are located at the loors of a building or local stations, and such portions for each loor or station preferably consist of a push button or circuit opening and closing device, with a circuit connecting with a source of energy and one of such magnets at the central station. That is, the means by which each controller is released preferably consists of the magnet portion at the central station or where the controller is located, which is to be released, and another portion located at the local station or iioor of the building and connecting with the magnet portion to energize the same. The circuits for push button devices N and N are as follows: from source of energy P by wire 24 to push button N, and thence by wire 25 to magnet M, and then, by wire 26, back to source P; from this same source by wire 27 to magnet M and thence by wire 28 to push button N and then, byrwire 29 back to source P.

As shown in Fig. 1 there are two cars, each provided with a signaling device, and a floor or local station signal for each of two floors or local stations, for each car, dia- Y grammatically arranged. Thercar signals G and G are located, one in each car, and, as before explained, each signal device in 4each car is to be operated as the car moves in either direction. The floor or local station signal devices H, H, H2 and H3 are Ato be operated only as the car moves in one of its two directions of movement, each car shaft being provided with separate signal devices at the floors or stations, which are operable only on the movement of that particular car. It is customary to provide two 'sets of such separate floor or sub-station signals, one operable as the car moves upwardly and the other as suoli car moves downwardly, one signal device of each set being arranged at each station or floor, eX- cept the upper and lower iioors. As shown there is a separate switch device for eachV floor or sub-station signal device and for each signal to be given within each car, as it moves up and down and approaches each of the floors or local stations. Also there are as many controllers asthere are signal devices at each floor or station to be operated, that is yone at each floorof the building for the upwardly moving cars and one for the downwardly moving cars, except the top and bottom iioors or stations, that are to be served by any given system or apparatus. Y Y

g The circuits by which the signal devices 1n the cars may be operated are as follows: from source of energy P by wire 1 to wire 2 to signal device G in car A and thence by wire 8 to the pair of terminals of switch device B7 on controller D and thence by wire 4 to wire 5 and back to the other side of source P, then, from source P by wires 1 and 2 to signal device Gr again and thence by wire 3 to wire 6 and the pair of terminals b5 of switch device B5 on controller D Vand then from such terminals by wire 7 to wire 5 and source P; for signal device G in. carrA the circuits are from source P by wire 1 to wire 8, thence to device Gr and thence bv wire 9 to the pair of terminals b3 of switch device B3v on controller D and then by Vwire 10 to wire 5 and back to the other side of source P;Ythen from source P by wires 1 and 8 to device G again, thence by wire 9 to wire 11 to the pair of terminals b of switch device B on controller D and thence by wire 12 to wire 13 to the other side of source P.

The circuits for the floor or station signal devices H, H, H2 and H3 are as follows: from source P by wire 1 to device H3, thence by wire 1l to the pair of terminals be of switch device B6 on controller D and thence by wire 16 to wire 5 and back to source P; from source P by wire 1 to device H2, thence by wire 17 to the pair of terminals b4 of switch B4 and then by wire 1S to wire 5 and the other side of source P, from source P by wire 19 to device H', thence by wire 22 to the pair of terminals b2 of switch B2 and Vthen by wire 28 to wire 18 and the other side of source P; from this source again by wire 19 to device H and thence by wire 20 to the pair of terminals of switch device B and by wire 21 to wire 13 and thence to source P. As thus shown a person on the floor or at the substation where push button device N is located desiring to signal the first car going in a downwardly direction he would actuate the push button device N, which wouldrenergize the electromagnet M, release controller D and permit spring E to move such controller and the switch devices carried thereby into operable position or condition so that each device thereon could be operated by its particular car. Then the rst one of the two cars, A and A, which reached its particular switch device on controller D would have its carriage or actuat-` ing means in position to engage with the actuating parts of that particular pair of switch devices and actuate them as such means first engaged therewith and closing the circuits connected thereto, the actuating part, as a', a3, a5 and a7, of .each pair of devices continuing to rotate on its stud and moving the controller against the stress of its spring into position for it to be held by the projection on the armature of its electromagnet, where it would be held or maintained until the push button device N was again operated. After the actuating and movable parts of such pair of switch devices had closed the circuits the retaining devices connected therewith would, under the stress of their respective spring or springs, move into position to engage with such movable parts, after the actuating means cease to control their movements, and hold the circuits closed for the desired extent of movement of the actuating means, when the abutment or abutments or abutting surfaces, as J, J, J2, and J3, which are to abut against the forward end or ends of such retaining devices will force such devices out of engagement with such movable parts and the circuits will be broken by the opening of the pair or pairs of terminals with which they connect when the signal devices will cease to operate until the switch devices are moved from their inoperable condition to the operable, and the actuating means has again closed such circuit or circuits. From this it will be seen that the car and carriage which first reaches a position to actuate a pair of switch devices, after they have been brought into operable condition or position, and the actuating means operate the saine restores or returns such switch devices, with all other pairs mounted to move with them, to their inoperable condition, or normal positions. It will also be seen that the circuits remain closed, after the switch devices and controller have been restored or returned to their normal positions, or the positions where the switch devices are inoperable by the actuating means, and until the coacting abutment or abutments, as J, J', Src., actuate the retaining devices, as described. That is, the opening of the circuits are not dependent necessarily upon the movements of the parts which were actuated to close them. Because of this peculiarity of this construction the portions, as c, 0, c2, &c., of the actuating means may be of any desired proportions, so that the signal devices for any given iioor or substation may be made to operate at any given point in the movement of the car relatively to any given floor. For instance, if it is desired that the floor or station signal shall begin to operate, say when the car has reached a point three i'loors or stations of the one where the push button device is located the parts or portions, as c4 c5, &c., will be long enough to engage with the switch devices corresponding to the floor where the push button is located to do this, and then the signal device for that floor will begin to operate when three floors or stations away and continue to operate until the car has reached a point where it is desired to have such signal cease operation, as, for instance, when the car has just passed by the floor or station where the push button is located, or any other desired point.

Sometimes it is desirable that a car shall not be stopped by the operator too quickly, as, for instance, within a distance of that between two ordinary iioors of a building, or some other distance and that the signals in the car and at the floor shall not be given when a car has reached a point within such distance. If it is desired to do this these portions, as c, c', c2, c3, 0*, &c., may be cut short, as shown in Fig. l, so that there is a distance corresponding to two ordinary floors between such portions at one end of the carriage and the corresponding portions at the other end, one halt of such distance being as the car approaches the floor in one direction and the other half as it approaches that ioor in the other direction. Then, when a car has approached within one iioor of the point where a push button device is located and such device were to be operated, no signals would be given by the continued movement of that car and would be given by the next approaching car moving in the same direction. The distance between the two portions of the actuating means may be made such as is desired in each individual system or apparatus.

Sometimes it is desired that the signal device in the car shall not begin to operate until some little time after the device at the floor or station has begun to operate. When this is desired the port-ions, as c, c, c2, &c., may be made as shown in Figs. l, 11 and 12, or otherwise, as desired. Also the abutments, as J, J', &c., may be arranged so as to cause the signals to cease operating at different times, also as shown in Fig. 1, as each switch device is operably independent of each of the others, and each retaining device is also operably independent of the others, hence each switch device may begin and cease to operate at any desired point in the movement of the car and carriage relatively thereto.

The use of teeth or a roughened surface for the actuating means and actuating parts to engage with permits the actuating parts to be carried by the controllers and to be quickly and surely operated when brought into operable position, as the portions of the actuating means, as c, c', c2, c, 0*, &c., are passing by such parts. These teeth or surfaces also permit the switch devices and controllers to move substantially their full extent into their operable condition as such portions are in the path of movement of such switch devices. This isthe case whether the actuating means be at the moment moving in one direction or the other, or ismomentarily standing still in such path of movement. Y f y The springs which are shown as moving the controllers and switch devices into operable condition or positions act continuously, exerting their force to move such controllers in one direction and opposing their movement in the other direction. Thus when these controllers whave reached the limit of their movement under the stress of Ytheir springs such springs hold them in such positions until an overpowering force moves them therefrom. Such springs also hold the actuating parts of the switch devices in engagement with the actuating means and Vthus insure the proper actuation thereof.

They do this at all times whether the car backs up or down, as when itV has run past a 'floor or in the regular operation of the car.

Instead of employing the form of switch devices seen in preceding figures other terms or yconstructions may be' employed, which embody in substance the combinations of members or devices particularly pointed out in some ot the claims hereunto annexed. As for instance such as are shown in Figs. 13 to 18, inclusive, where special retaining means to hold the circuits closed are not employed. The actuating means mounted to move relatively to the switch devices in a measure do the work done by the special retaining means shown in preceding figures of the drawings. 1n Figs. 13 to 18 only one switch device is shown, but pairs of such devices may be employed, if desired, by simply duplicating the pair of terminals there seen, the lever which coacts therewith, the two arm spring and the portion of the actuating means, which operates said lever, as the same are here shown. Of course in that case the stud on which such lever is mounted and the pin or projection on the controller with which the two arm spring coacts would have to be increased in length to receive and hold the lever and spring. D2, may support as many individual switch devices, as desired, whether it be one or more. Each switch device, as B8, may consist of a pair of terminals as b3, an actuat-V ing lever, as as, a two arm spring. as rs, and a stud, as ds, mounted in controller, as D2. The actuating lever as has only one tooth, instead of several teeth, as in preceding iigures, and is, as shown, arranged to engage with the teeth on the portion 0S of the actuating means and move equally in two directions, accordinglv as the actuating means, as C2, moves. This lev r, as as, in moving in one direction closes the circuit through terminals, as bs, as seen in Fig. 16, and in movingin the other direction moves away from such terminals, as seen in Fig. 17, and the circuit remains open.

The controllers carrying switch devices, as

Each controller, as

B8, may be'provided with springs arranged as springs 'E and E arearranged in Fig. f1', Y

and such controllers may be held or maintained in positions where the switch devices, carried thereby are inoperable upon the passage of the actuating means mounted to move relatively thereto in the same manner and by the same kind of'means as are em- Y The means shown by which each of theseV controllers are moved from the position where the switches are operable to the position where the switches are inoperable are of substantially the same general character as those seen in preceding iigures, but they are so arranged therein, orcombined together, that the actuating means maintain the circuits vclosed Vduring the desired extent of movement of the car without the aid of other and separate devices and then the controller and its switches are restored or returned to their normal positions with the switches in their inoperable condition. means for one car, when moving in one direction as C2, are shown more or less vin Figs. 13, 14, 16 and 17, and such means may be mounted to move relatively to the switch devices in like manner that the carriages or actuating means C and C are mounted to move, in Fig. 1.V rllhe teeth in the portion cs of actuating means 2, with which the levers, as as, engage, are shown as made of a greater depth than the teeth shown in preceding figures. This causes the levers to be moved a greater distance before passing out of mesh with the rack teeth and sliding over the rel Ymaining teeth while holding the circuits closed. vWhen any actuating lever is moved such means are passing the lever, it will be actuated the same as if such lever was brought into the operable position before such means had reached it, but it will not be held in the actuated or operated position tor so great an extent of movement of such means, as when such lever is in such position before the means has reached it. The operation is substantially the same in one case as in they other. 1n this respect the operation of these actuating leversis somewhat like that of the actuating parts in preceding tigures, so far as concerns the action of the actuating means thereon before reaching and in passing byV suchparts.

A restoring part, vas a9, substantiallyof the construction seen in Fig. 9, kbut of greater eccentricity, is mounted on the same stud as actuating lever as is mounted, and it is proyided with a two arm-spring, as '119, as shown 1n preceding figures and more particularly The actuatingv in Fig. 18. On the carriage or actuating means C2 there is mounted a short section of a rack, as 610, in position to engage with restoring part, as a9, and as such part rotates on its stud to force it and the controller into position to be held by the means provided for this purpose, that is, into the position where the switches are in their inoperable condition, and the teeth on the parts cs and 010 will not engage with the parts as and a2. As shown in these Figs. 13 to 18 a stud or projection, as g', on the controller, as D2, engages with a projection, as m2, on armature, as m0, which is mounted to coact with electromagnet M2. A spring, as E2, engages with the end of controller, as D2, and with a portion of the bar Y2, the stress of which continuously tends to move the controller D2 toward the carriage, as C2, and to bring the parts, as as and a2 into position to be engaged with parts 0S and 01, respectively, the controller and the parts carried thereby being held against this tendency by the armature, as m, and spring m2, in like manner that each of the controllers is held in preceding gures. The controller, as D2, may be released from the restraint of armature, as m6, by energizing electromagnet M2, as in preceding iigures, or otherwise.

In Figs. 13 and 15 the pair of terminals, as bs, and the controller, as D2, are shown in the positions they occupy when moved into position to have actuating means c2 and c1 engage with lever, as as, and controller restoring part or device, as a2, to first operate the signal device and restore the controller and parts supported thereby to the control or restraint of the armature, as m6. In Fig. 16 the portion of the actuating means, as c2, has moved in the direction of the arrow suiiiciently to engage with the lever, as as, actuate the same and close the terminals, as 58, and as such portion continues to move the end of the lever in engagement therewith moves with it and the terminals are held in contact until the last tooth on the portion, as cs, has passed beyond the lever, as as, when the two arm spring, a s 71S, returns such lever to its normal position, as seen in Figs. 13 and 15. When this has occurred the restoring part or device, as a, engages with the part, as 010, which is in a different plane from that of 08, as seen in Fig. 14, and as such part continues to move the eccentric or cam part, as a2, rotates on its stud or support, as cls, and the controller is forced away from the path of movement of the carriage, as C2, until it is engaged with the armature, as m0, and the lever, as as, is out of position for the portion, as- 0S, of the actuating means to engage therewith, and, hence, such lever and the switch device are inoperable, and are in what may be aptly termed their inoperative positions or condition. It is desirable that the controller or controllers, as D2, shall always move into the operative position, when once released from the restraining or holding action of the armature or armatures, as m6, to substantially the full extent of their movement, whether the actuating means be in position to engage therewith or not, and also whether such means be moving in one direction or the other. This is accomplished in the construction seen in these Figs. 13 to 18, as it is also, in the case in preceding figuresn The tooth on this lever, as as, or the teeth on the parts, as shown in Figs. 9 and 10 engage with the rack teeth on the actuating means as soon as such means are in position for this to be done, and if such means move in one direction the switch terminals are closed, but if such means move in the other or opposite direction, then the switch terminals are not disturbed, because the coacting parts are moved in the wrong direction in such case and the switches will not be operated. This is illustrated in Fig. 17 of the drawings. As there shown the portion, as c3, of the actuating means is moving in the opposite direction to that in which the same means are shown as moving in Fig. 16, and the result is that the lever, as as, is moved away from the terminals, as bs, of switch B8, and of course such terminals are not disturbed in the least and consequently remain open. The action of the portion, as 010, of the actuating means upon the cam or eccentric part, as a2, when such means move in the direction of the arrow, as indicated in Fig. 17, is to move the cam face or portion of such part away from the portion, as 01, and as a consequence the controller, as D2, remains undisturbed and is not forced against the stress of its spring, as E2, to any substantial extent, and such means may pass by such switch device leaving it unoperated and ready to be operated, when such means move in the proper direction to do this.

The operation or the parts seen in Figs. 9 and 10 is substantially the same as of the parts seen in Figs. 13 to 18, in the above respect, as well as in some others. Thus it will be seen that these movable parts, as a3 and a2 of Figs. 6 and 7 and as a2 and a of Figs. 13 to 18, are actuable by the springs, as E, E and E2, into engaging position or relation with their coacting parts, as c3 and c7 and cs and C10, which are mounted to move relatively to such movable parts in two directions, and that such parts are held in such engaging position or positions by springs, as E, E and F12, and that each part may move in either of two directions, accordingly as such coacting portions move in one or the other of suoli directions; also that such coacting portions are adapted to move suoli cam or eccentric parts relatively to the controller or controllers and restore the switch device or devices to their normal positions or conditions, that is, where the Switches are in their inoperative condition. In these Figs. 13 to 18 the two arm springs operate the .same as in preceding figures, notwithstanding that the stationary or fixed pin or projection attached to the controller occupies a different position relatively to the pins or projections on the movable and actuable parts by the movement of which the switches are operated and the circuits closed from the positions shown in such other figures. In Fig. 18 the fixed pin or projection u8 is attached to the controller, and the pins or projections a5 and us are attached to the movable parts as and a", respectively. As thus arranged the fixed or controller pin or projection is the farthest from the stud on which the movable parts turn, in these Figs. 13 to 18, while in preceding figures this fixed or controller pin is the one nearest the stud. Switch devices, as B8, may be connected with the circuits, signal devices, source or sources of energy and push button devices, in substantially the same manner diagrammatically illustrated in Fig. 1, if desired, or in other desired manner or manners.

Instead of employing switch devices of the general character seen in preceding figures switch devices of the general character of those shown in Figs. 19, 20, 21 and 22 may be employed with like results in many of the combinations hereinafter pointed out without changing or materially affecting the mode of operation of each of such combinations. Switch devices of this general character are shown and described in an application Serial No. 284,357, filed No-r vember 26, 1904;. The switch devices, as B and B10, are here shown as mounted on bars or controllers, as D3 and Dt which in turn are mounted in bars, as Y, Y having springs, as E4, and E to move the controllers into position where the terminal or terminals of the switch devices may be closed, all substantially as in the case of the controllers seen in preceding figures. That is, the means for moving the controllers to bring the switch devices into operable condition, to hold them there, to hold or retain them in their inoperable condition and to release them may be of the general character or constructions, seen in preceding figures, or be varied therefrom so long as the mode of operation of each of such combinations be not materially changed. In the construction here shown the movable or actuable parts with which some portion of the actuating means co-act in order to close the terminals and operate the signal devices are not mounted on the controllers or movable bars, as D3 or D4, but are separately mounted and are normally in posi.- tion to be actuated by the means mounted Y this work. In Figs. 19, 20 and 21 such actuable art as am is mounted on a Xedv support in the form of a` stud or pin o mounted in a bar or standard V affixed to the frame of the machine in any convenient way to hold such actuable part in position. In Fig. 21 this actuable part is shown in its normal position, always ready to be operated by the movement of the carriage, as Ct, and the portion, as 012, past it in either direction of its movement relatively thereto. The controller D3 and switch device Bg are also here shown in position for the circuit or circuits to be closed upon the actuation of the lever, as 612, by the portion of the actuating means, as cl2, moving upwardly, or in the direction indicated by the arrow in Fig. 19 into the position there shown where the terminals, as b9 are closed and will remain closed until the abutting portion of such means, as 012, has passed entirely beyond and out of engagement with such lever and it is free to assume the position seen in Fig. 21. This lever, as am, is also preferably provided with a two arm spring as T12, best seen in Fig. 20, acting substantially in the manner that the other two arm springs, heretofore described, act. This spring, as T12 is mounted on the hub of lever, as (L12, and one arm passes under and at one side of two pins or projections, as e012 and M13, and the other arm of such spring passes under and at the opposite side of these same two pins or projections. One of these two pins or projections, as U12, is secured to the lever', as a, and the other one, as M13, is affixed to the standard or bar V. The controllers, as D3 and D4l are preferably returned or restored to their normal positions, that is, the positions ywhere the switch devices are in an inoperable condition by a portion on the actuating means and a coacting roller or abutting surface on the controllers the two things coacting together to accomplish this work.

As shown in Figs. 19 and 20 an abutment or roller, as o is suitably mounted on controller D3 with which a surface preferably inclined, on a piece or portion, as n, coacts, which is mounted on the actuating means so as to move therewith and through the action of one on the other the controller is forced endwise away from the path of movement of such actuating means into its normal position where it will be held until again released, as before explained. There are two of these abutments, as n and nl, shown, one, as n, to act on the up controllers, as the carriage moves in one direction and the other, as fn, to act on the down controllers, as the carriage moves in the other direction, each having the same mode of operation. vThe carriage and actuating means are preferably to be substantially divided midway of their length, and each division is a substantial duplicate of the other and are made to coact with their respective parts or switch devices in substantially the same way to produce the same result. These parts, as n and n', are preferably pivotally attached to the actuating means and yieldingly held in their normal position by springs as shown or otherwise, as desired. Then thus attached these parts, as n and n, yield, as the actuating means move in one direction and permit such parts to pass by their respective controllers without actuating them, but are held against yielding when such parts move with the actuating means in the other direction and when so held they operate the switch devices and restore the controllers to their normal position or positions as more clearly explained in said application. It desired only one terminal of each switch device may be carried upon the controllers and yet substantially the same mode of operation be had, as if both terminals were thus carried, as indicated in Fig. 22. In this ligure, as in preceding figures a portion of the controller is broken away to better show the parts directly behind it.

As shown in Fig. 22 one of the pair of terminals, as Z110, is mounted on a block, preferably of insulating material, which block is shown as secured to the bar or standard V, to which lever, as a, is pivotally atlixed, and hence is always in position to be actuated by such lever, when moved in one direction by the action of the actuating means, (not shown, but of substantially the same construction as means 012, seen in Figs. 19 to 21,) which are mounted on a carriage to move relatively thereto and actuate such lever, as lever am is actuated in these Figs. 19 to 21, and with like results. As shown in this Fig. 22 the controller, as D4, is in the position that the part, as als, when actuated, would not move the terminal mounted on the block into contact with its companion terminal carried by the controller, as Dt, but when the controller is released and is free to move under the stress of its spring, as E5, it will be moved toward the right into position, so that upon actuating such lever, as als, the two terminals, as 610 will be brought into contact one with the other and the circuit closed, the same as in preceding iigures of the drawings. Otherwise the operation of this construction is the same as that shown in Figs. 19 to 21, inclusive, and will be fully understood without further explanation.

In each of the constructions herein shown and described the circuits are normally in an inoperable condition by reason or the switch devices being normally in positions where their terminals cannot be brought into contact by the means provided for that purpose. These switch devices and the circuits controlled by them are to be brought into operable condition as desired by any suitable means desired to be operable from a floor or station from which a signal is to be sent and given in the desired position or positions, and for the desired length of time or extent ot movement of a car or similar moving object. The portions of such means which are operable from the floors or stations are of suoli a construction and arrangement that the switch devices are released and continuously acting means move such devices from a position or positions where they cannot be operated into a position or positions where they are operable, and are held there by such continuously operating means until the signals are given and the controllers are returned or restored to the position or positions where t-he switch devices are again inoperable.

In a signaling apparatus for elevators in combination, a plurality of cars and shafts, up and down stationary electricallyoperated visual signals for each iloor and shaft, normally-open circuits for operating the signals, means for controlling said circuits and signals and comprising tivo signal controllers corresponding to each floor, one adapted to control said up signals of all said cars for that floor, and the other the doivn signals, each controller being provided vvith means tending to move the same from its normal inoperative position to an operative position, detent mechanism for each controller holding it in its normal inoperative position, electro-magnetic mechanism for releasing said detent mechanism, up and down passengers switches located at each of said floors and each adapted to cause its corresponding electro-magnetic mechanism to be energized, restoring mechanism comprising an up and a down movable device for each car moved correspondingly with but much sloiver than said car, each of said devices being' adapted to mechanically move their respective signal controllers in succession back to normal position and alloiv said detent mechanisms to thereafter hold the same, said restoring mechanism also comprising means render-in(y said up movable devices inoperative to rest-ore the up signal controllers when thc cars are moving down, and vice versa, said signal controllers and detents and movable devices being grouped together.

19. In a signaling apparatus for elevators in combination, a plurality of cars and shafts, electrically-operated visual signals for signaling the operators of the cars, normally-open circuits for operating the signals, means for controlling said circuits and signals and comprising a signal controller corresponding to each floor and each adapted to control said signals of all said cars, each controller being provided with means tending to move the saine from its normal inoperative position to an operative position, detent mechanism for each controller holding it in its normal inoperative position, electro-magnetic mechanism for releasing said detent mechanism, a passenger`s switch located at each of said floors and each adapted to cause its corresponding electro-magnetic mechanism to be energized, restoring mechanism comprising a movable device for each car moved correspondingly with but much slower than said car, each of said devices being adapted to mechanically move said signal controllers in succession back to normal position and allow said detent mechanisms to thereafter hold the same, said signal controllers, detents and movable devices being grouped together.

20. In an elevator signaling apparatus in combination, a pair of shafts and cars, normally-inactive electrically-operated signals for the operators of said cars, a passengers button at a ioor, a signal controller corresponding to said floor adapted to at least in part control the signals of both said cars and in a given location with relation to the movement of said cars but slightly movable, detent mechanism controlled by said push-button and adapted to normally hold said controller, restoring mechanism comprising a car-operated part for each car moved correspondingly with but much slower than its car, and intermediate mechanism between said controller and both said car-operated parts, said intermediate mechanism being constructed and arranged to have an automatic tendency to move in one direction and adapted to be mechanically moved in the opposite direction by said car-operated parts and thereby move said controller back to its detent-engaged position, said intermediate mechanism then automatically returning to its own normal position after said car-operated parts have passed away from the same.
