Application my 21, 1937, Serial No. 154,709 18 Claims. (01. 84-103) This invention relates to electrically controlled devices for controlling a plurality of different electrical circuits adapted for successive energizatlon.

One object of the invention is the provision of an electrically operated apparatus having a plurality of electrical circuits connected to contacts which are successively engaged by a motor driven contact member, a suitable lost motion attach ment being provided between the contacts and the motor providing a snap action from one contact to another.

Another object of the invention is the provision of an electrically actuated apparatus incorporating different electrical circuits connected to a series of contacts which are swept over by a motor operated contact member, one of the contacts being incorporated in the motor energizing circuit, the construction being such as to provide a substantial degree of motor operation while maintaining an electrical engagement between the contact in the motor energizing circuit and the contact engaging portion of the motor driven member, additional means being provided to continue the operation of the motor for a predetermined time.

Another object of the invention is the provision of an apparatus, such as an electric chime having a plurality of chime members operated by solenoid plungers, the plungers being energized successively by a motor driven apparatus including a rotatable arm and a series of projecting contacts over which the contact engaging portion of the arm moves with a snap action from one contact to another.

Another object of the invention is the provision of an electrically actuated chime adapted to produce a predetermined sequence of chime notes each time a circuit controlling motor is energized, and having simple electrical means operable to readily change the sequence of notes produced.

Another object of the invention is the provision of a motor driven circuit controller, controlled by a switch which may be held closed for only a very short time, and having provision insuring the initiation and completion of a full cycle of operations, and insuring the stopping of the motor at a predetermined time so that it will be ready to start again on a second cycle.

Another object of the invention is the provision of an electrically actuated chime or the like, having a relay providing a holding circuit and incorporating a switch which is actuated shortly after a sequence of operations is initiated to provide continued operation of a drive motor throughout a predetermined time interval and providing deenergization of the relay which is therefore maintained energized only a comparatively small part of a complete cycle of operations.

Another object of the invention is the provision I of an electrically actuated chime or the like adapted to produce a predetermined energization of a number of different electrical circuits and controlled by an electric motor having a cam member which actuates a switch providing con 10 tinued operation of the motor and in which the switch operating member also functions as a stopping means at the end of a cycle of operations, insuring a positioning of the motor operated parts such as to permit the motor to be again started for another cycle.

Another object of the invention is the provision of an electrically actuated chime incorporating a series of solenoids carried by a supporting member which may be mounted on a wall sur- 20 face or the like, the solenoid plungers being contained, when in their inoperative positions, in cages or barrels which project rearwardly from the supporting member and which are adapted to be mounted in holes of comparatively small size 26 in the wall. or other supporting surface.

Another object of the invention is the provision of an electrically actuated chime incorporating a plurality of chime tubes operated by solenoids the coils of which are housed in a container hav- 80 ing a depth only slightly exceeding the length of the solenoid coils.

..Referring more particularly to the drawings by reference numerals, Figs. 1 to 5 inclusive show an electrically actuated chime mechanism including chime tubes II, II, l2 and If each of which is controlled by an electric solenoid. Thus, as illustrated in Fig. 2, the chime tube I2 is adapted to be struck by the plunger ll of the solenoid I! when the winding I1 is energized, the plunger ll having an iron body part which is centered within the length of the coil it, under the pull of the winding, when the striking tip I8 is a small fractional part of an inch away from the surface of the chime tube l2 so that the chime will be struck and the plunger will be retracted a very slight amount to permit the continued vibration of the chime. Normally the plunger II is held in a retracted position as shown in Fig. 2 by means of a spring 20 which bears against an end plate 2| fixed on the end of the plunger and holds the end of the plunger against a soft packing wad 22 contained in a barrel or cage 23, preferably made of brass. This brass cage guides the rear end of the solenoid plunger, which is provided with a non-metallic washer or bearing strip 24 of substantially the same diameter as the inside of the cage 2!,

The solenoid coil I1 is supported by a housing plate 20 which is preferably a sheet metal stamping formed to provide a front plate 21, rearwardly extending upper and lower plates 28, and vertically extending back plates 29, the latter being adapted to be mounted flush or flat upon the surface of a wall or other holding object. Suitable attaching screws 20 pass through openings in the back portions 20 and serve to mount the housing plate 20 securely on the wall ll.

At the rear of the housing in which the solenoid coils are contained is a back plate 33, preferably a sheet metal plate having openings 24 receiving the several brass cages 23, the plate 33 being formed to provide forwardly extending side portions 36 which are attached by means of scrws 31 to the housing plate 28. Some little distance in front of the back plate 23 is an iron strap 39 which extends along the series of solenoid coils, holding the coils against the front plate 21 of the housing, iron bolts or screws 40 serving to interconnect the strap 38 and the steel plate 21 magnetically as well as mechanically.

The ends of the cages 23 are preferably pressed into openings provided therefor in the strap 20. Pressed into the cage 2!, as shown in Fig. 2, is a brass collar ll which holds the rear end of a brass sleeve 42 around which the winding I1 is placed, the forward end of this brass sleeve 42 having a pressed fit in openings provided in the front plate 21 of the housing. It will be understood that the several solenoids, four in number in the particular construction herein illustrated, are all of similar construction and are similarly mounted in parallel arrangement with their axes extending horizontally and rearwardly in alignment with the central vertical planes of the chime tubes.

Several chime tubes are supported by flexible cords N which pass through openings in the upper ends of the chime tubes, and which are hung from a common supporting bar 45, the latter having slots 48 which receive the upper looped portions of'the cords ll. These slots are so arranged that the cords will not touch the chime tubes except where they pass through the tubes. permitting unrestrained vibration of the chime tubes. The common supporting bar ll is secured at its opposite ends by means of attaching screws 41 to the front plate 21. The holes in the bar through which the screws pass are preferably somewhat larger than the outside diameter of the screws to permit a slight adjustment in positioning of the bar. Inasmuch as the slots 48 may have a definite location with respect to one another and with respect to the predetermined spacing of the axes of the solenoids, it will be apparent that the chime tubes are very readily located so that they are exactly centered with the solenoids.

The upper ends of the chime tubes are protected and covered by means of a cover 4! having a top surface Ill and a depending front surface 5| suitably spaced from and covering the upper ends of all of the chime tubes. The cover is also provided with side walls 52 which house and enclose the side portions of the chime housing. The cover is readily secured in position on the chime housing by suitable attaching means at the rear end of the top wall 50. As shown this attaching means comprises depending members 54 which extend down into receiving sockets II provided in the top vertical plate 29 of the housing. To remove the cover 49 it is merely necessary to move the same vertically upwardly to disengage the depending portions 54 of the cover from the receiving sockets in the housing plate.

As will be readily apparent from Fig. 2, the total depth of the housing in which the solenoid coils are contained only slightly exceeds the length of the coils. The barrels or cages 22 pro- Ject to the rear of the back end of the housing and are received in four round holes or openings in the wall 3|. These four holes in the wall may be readily made by a suitable drill or similar tool and the engagement between the barrels or cages 23 and the wall openings assists in assuming the weight of the chime apparatus although the holes in the wall may be made slightly larger if desired so that the entire weight of the apparatus is assumed by the screws It. The construction, however, provides a chime apparatus which will not project very far from the wall and in which the flat rear side of the apparatus may be mounted flush or flat upon the wall.

In accordance with the present invention the solenoids of the chime apparatus are adapted to be successively energized in a predetermined manner by an electrically actuated controlling mechanism including an electric motor and circuit controlling apparatus operated by the motor to produce a predetermined sequence of sounds, it being understood that the several chime tubes are all of different tune such, for example, C, 1", A, C. It is preferred that the circuit controlling apparatus be mounted in a common cabinet and that there should be suitable electrical connections extending from the cabinet, which may be at a remote point in the building, to the chime apparatus in which the solenoids are contained.

As shown in Figs. 7 to 10 inclusive, the circuit controlling apparatus is contained in a cabinet 51 having a mounting panel 68 of suitable insulating material. Attaching screws I support the panel 58 at a suitablelocation near the front of the cabinet. Within the cabinet walls, which are preferably of sheet iron construction, is the transformer 59 adapted to transform the ordinary ll house lighting voltage to a suitable low voltage, preferablyof the order of 16 volts. Carried by the back of the panel 88 as by means of suitable supporting connections 88 is an electric motor 8| having winding 82 which is energized from the low voltage secondary of the transformer. The motor shaft 82 is suitably connected to a rotatable shaft portion 83 which is mounted for rotation in the panel 88. A suitable flexible connection between the motor shaft and the shaft portion 88 may be provided by a pin 84 on the motor shaft and pin receiving slots 88 in the shaft portion 83.

The front end of the shaft portion 88, as shown in Figs. 6 and 9, is secured to a hub 88 by means of a suitable set screw 81. The hub is pinned securely to a slotted or cam member 88, preferably made of Bakelite, and provided with a series of slots 88 spaced in a predetermined arrangement around its periphery. This member 88 forms a stopping means for the motor and also operates a switch lever 18 which closes a circuit shortly after the motor is energized to provide for continued operation of the motor. Thus as shown in Fig. 6, the lever 18 which is preferably a rigid brass member, is pivotally supported at H on the face of the panel 88. Projecting from the lever 18 is a projection 12 one side of which extends abruptly from the lever and the other side, as indicated at 13, is inclined so that when the slotted member 88 rotates clockwise from its position shown in Fig. 6 it will operate as a cam against the surface 18 of the projection and force the lever towards the right.

- The end of the projection 12 will then ride along the cylindrical outer surface of the slotted member until the next slot comes opposite the projection, which will then permit the lever 18 to move back to the left, this movement serving to impose a restraining effect on the continued rotation of the slotted member by reason of its engagement with the surface I3 which is so arranged that the spring 14 yieldingly holds the projection 12 in the slot. This tends to stop the motor driven slotted member 88 at a definite stopping point. The free end of the lever 18 carries a contact member 15 which engages a fixed contact 18 when the lever 18 is moved to the right from its retracted position, so that a circuit is completed from contact 18 to contact 15, these contacts thus completing a circuit which malntains the motor in operation as will be presently described.

The contact member 15 is preferably a rigid blade of brass or other similar metal held yieldingly against a flat surface I8 on the lever 18 by means of a spring III, the construction being such that an electrical connection is made between the parts 18 and 18 just before the lever 18 is moved entirely clear of a slot 88 so that there will be assurance of an electrical connection between the parts 15 and 18 when the end of the projection I2 is riding on the cylindrical surface of the slotted member 88. Fixed on the member 15 is a semicircular ball portion 15 engaging a semicirculardepression in the lever 18 and acting as a fulcrum point.

Carried by the hub 88 is a rigid arm 88, of brass or other similar material. The end of this arm carries a contact engaging portion or brush 8| which sweeps over a series of contact studs or pins 82, making contact successively with these contact pins, and providing for sequential energization of the circuits in which the pins are connected. These contact pins 82 are preferably agrammatic manner.

nected by a wire 88 to brass studs having a forced fit in the panel 88 and extending from both sides of the panel as shown in Fig. 8, the forwardly projecting ends of the studs being engaged by the contact portion II of arm 88 as previously mentioned. This contact portion is such as to provide a snap action for one contact pin to another while the motor driven hub 88 operates at a uniform speed of rotation. There is thus some motion of the motor during which a contact pin remains in engagement with the contact portion II. This contact portion II is preferably constructed as a copper brush or blade having a tail portion 84 projecting through an opening in the arm 88 and engaged by-a spring 88 which is anchored at one end to a pin 88 on the arm 88. The spring 88 yieldingly urges the contact portion 8| in a clockwise direction with respect to the arm 88, as viewed in Fig. 6, and as the contact portion 8| projects out to a greater radial extent than the pins 82 when the spring 88 is compressed it will be apparent that the contact portion 8| snaps quickly into engagement with a succeeding contact pin 82 as soon as it releases from the preceding pin.

The rearwardly projecting ends of the pins 82 are connected electrically in a predetermined manner to the different solenoid circuits, and certain pins are connected to one another by means of wires 88, as shown in Fig. 10 for example, which are looped around certain of the pins and are preferably soldered in place. As shown in Fig. 10 four of the pins are interconnected by means of wire 88. These pins are arranged 90" apart. These particular pins, designated 98, connect to a wire 8| that is connected in the motor energizing circuit as will be presently described. Other pins 82 positioned at 45 away from the pins 88 are also interconnected to one another in a similar manner and are connected to a common wire 83 also forming a part of the motor energizing circuit. The remaining pins are connected by a similar looped wire arrangement as illustrated in Fig. 11 in a di- The several connecting loops of wire which interconnect the pins with one another are separated electricallyby means of insulating disks 94 shown in Figs. 8 and 9.

Referring now more particularly to Fig. 11 it will be seen that the transformer 58 is provided with a primary winding 88 which may be connected through a suitable switch, not shown, to a volt power source. The secondary 81 of this transformer is connected through a fuse 88 which is preferably supported on the panel 88, to a contact 5 which is arranged conveniently upon the panel as shown in Fig. 6. The other end of the winding 81 connects to the panel connection or contact 6 which is electrically conthe motor driven brass arm 88. Contact 8 is also connected to a manually operated starting switch I88 through wire I8I. Switch I88 is connected by wire I82 to the winding I83 of a relay having an armature I88 which closes switches I85 and I88 when the relay is energized. When the starting switch I88 is closed a circuit is completed through 'the secondary of the transformer and through the relay I83, this relay acting instantaneously as soon as the switch I88 is closed so as to close a holding circuit established from the contact 8 through relay I83, through switch I85 closed by the relay and through the wire 8| to the contact pin 98 which at that time is engaged by the motor driven-contact arm 88. The relay I8; is

I'Ihisoccursoicourseassoonas thus maintained energized even though the manually operated switch III is released immediately aiter it is closed, to insure starting of the motor even ii the switch III is not held closed.

The motor circuit is established from the secondary oi the transformer irom' contact I through the switch III which is closed by the relay, through the winding I 0! the motor and back through the wire I" to the contact I oi the transiormer secondary. The motor will thus start to operate, and as it does so it will oi course rotate the slotted member 60 so that aitera short period oi operation the slotted member II will cam the lever II in a counterclockwise direction and close a maintaining circuit through wire III, the contact arm ll. contact II, contact It (not through switch Ill) so that the motor will continue operating until this maintaining circuit through the contacts II, I! is broken. the next slot receives the projection 12 oi lever ll, alter a 45 rotation oi the shalt n. It should be noted that the electrical connection through arm II and contact 90 is maintained tor a substantial period during which the motor operates, keeping the holding circuit through the relay I" and switch lll'closed until contact is made between the contact members II and 18. Alter this contact is made to complete the maintaining circuit oi the motor, the contact blade on the end of the motor driven arm ll moves away from the pin ii and the relay III! is thus deenergized during the continued operation of the motor. The relay is thereiore energized only comparatively small periods oi time during the initial starting operation oi each cycle. As the relay I is deenergized and switches I" and I" broken beiore the next succeeding slot is engaged by the projection 12 of arm II, it will be apparent that the motor will be deenergized and stopped as soon as the circuit through the contacts II and I6 is interrupted by the contact arm It. And as previously mentioned, the resistance produced by the curved side ll oi the projection 12 operating against the shoulder on the slotted member at the end of the slot serves to impose a restraining resistance insuring that the motor will stop. and not overrun unless the motor is again energized.

The tour chime solenoids, which are designated respectively In, in, la, and 4a in Fig. 11 are connected through a common wire III to a controllable resistance III which is preferably supported on the rear side of the panel 88. Its resistance may be controlled by a manually ad- Justable hand knob Ill adapted for convenient operation on the front oi the panel. The resistance is electrically connected by wire I I to the contact I leading to the secondary oi the transiormer. The iour solenoid windings are connected electrically through wires II, III, III, II! to connection contacts I. 2, I, and l res tively arranged conveniently on the side oi the panel 58. These connections are electrically connected by wires Ilia, Illa, Illa, and Ilia to the series of contact pins 82. For example, throughout the first 45 oi rotation oi the motor operated arm ll, aiter the contact brush ll leaves the starting contact pin 80 with which it is shown engaged in Fig. 11, it successively energises the solenoids la, la, la, and 4a in that order, and then engages a pin '2, and the motor stops, for at that time the next succeeding notch or slot in the member 8| causes the motor circuit to be broken. This break in the motor cirgscuitproducedbytheleverllleavesthecontact.

brush II in engagement with pin Ii ready for another cycle oi operations. It the manual switch III is closed again a second sequence oi operations will be produced, relay I I8 being anergized to close the motor switch Ill and then later being deenergised when the contact brush ll leaves the pin s: but the motor continuing to operate because by that time lever II has closed the maintaining circuit 0! the motor. The motor will thus operate to produce a diiierent sequence oi sounds by energizing solenoids la, la, la, and 2a in that order. The next succeeding 45 rotation of the motor driven arm may produce still another sequence oi sounds by energizing the solenoids in some other diil'erent pleasing order. Each 45 rotation of the shait U will therefore produce some predetermined series of chime notes through the entire 360 oi a complete revolution.

It will be noted that the tour contact pins II and the four pins I! are all provided in the motor energizing circuit, with the connections as illustrated in Fig. ll. However there is provision enabling the motor to continue operation through more than 45 oi rotation to produce a continuous 90 of movement and thus strike eight chime notes in succession. Thus as shown in Fig. 6 there is a manually operable switch member III which, in the position shown, holds a contact blade I2! to connect the pins I! through the wire a to the pins I. through the wire ll. However when this switch is moved so as to throw the switch blades III over to the contact I24, each time the motor driven arm engages a contact 02 a circuit will be completed through the relay Ill back to the secondary contact I thus closing the relay and maintaining the motor energized through the switch I" which is oi course closed when the relay is energized. Therefore even though themotor maintaining circuit through the contacts I! and II is interrupted by the lever ll moving into engagement with a notch in the slotted member N, the motor will be maintained in operation by the closing oi the relay. The contacts ll and It will subsequently be closed and the relay deenergized and the motor continues until Ilse next succeeding contact III is reached. These is.thus provision ior varying the sequence 01' sounds produced, and the number oi chime blows struck in any one cycle oi operations, this change being eiiected merely by operating the switch member III.

The chime tubes are also adapted to be operated individually by conveniently located manually operable switches or push buttons I10, I", III and lit, connected directly to the respective solenoids la, in, la, and 4a and connected to a common wire I" which extends to the wire ll so that when the motor operated arm II is engaged with a pin III a circuit will be completed back to the secondary of the transiormer when any one oi these switches or push buttons I" to IN is operated. However it the chime is under the control of the motor when any oi these switches is closed no circuit will be completed merely by the manual closing of the switchu because the contact arm It will not complete the circuit at that time. These switches may be placed at diiierent convenient locations in the building and serve as calls with special signincance to show where they originated by reason oi the particular tone oi the single chime tube which is vibrated.

A keyboard designated III may be provided the lost motion or snap action provided in the closing of the successive circuits through the contact pins, at least one of which functions in the motor controlling circuit, it will be seen that the motor may be started and may be operated through some substantial degree of rotation before the motor starting circuit is interrupted. There is therefore an assurance that a complete cycle of operations will be eilected each time the starting switch is closed.

It should be understood that while the particular adaptation for which this electrical switching apparatus is illustrated herein is for the energization of solenoids, it may be used for other purposes and uses.
