7 Claims.

The invention relates to mechanisms arranged to operate a plurality of devices or control a plurality of electric circuits or the like in a preselected manner at pre-selected time intervals.

An object of the invention is to provide an apparatus or mechanism of the character described which will effect the operation of a plurality of devices or units of machinery or apparatus in a manner whereby the operation of each 10 of said units may be pre-selected as to operating time for a long period in advance, such as during a day or week cycle, and to accomplish this with an apparatus which is considerably simpler and less expensive than other types of similar apparatus heretofore available and which will at the same time be sturdy in construction and substantially positive and fool-proof in operation.

Another object of the invention is to provide an apparatus of the character described which is particularly adapted for use in connection with radio receivers and may, when so applied, be used to select any of a plurality of broadcasting stations at predetermined time intervals throughout the full period of a day or a week.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in the claims.

Referring to said drawings:

Figure 5 is a vertical cross-sectional view of the-part of the mechanism illustrated in Figure 4, and is taken substantially on the plane of line 5 5 of Figure 4.

Figure 6 is a schematic wiring diagram of the electrical circuit involved in the mechanism.

Figure 7 is an enlarged fragmentary plan view similar to Figure 2.

Figure 8 is a fragmentary view similar to Figure 7, but further enlarged.

The time controlled actuating mechanism of the present invention and as disclosed in the accompanying drawings consists brieiiy in a plurality of electric switches which are adapted for connection in a plurality of control circuits, and 5 which are displaced in unison with a constant rate of speed in synchronism with time through predetermined paths of movement, and means mounted at predetermined distances along the course of movement of said switches cooperating l0 with means for causing an engagement of said switches by said iirst means and operation of said switches at predetermined time intervals.

Referring more particularly to the accompanying drawings the apparatus comprises a supl5 port 1, here in the forxm of a box-like enclosure having a bottom wall 8, side walls 9, intermediate horizontal walls il and l2, and a removable top cover I3. Mounted within the support at the bottom thereof is a clock motor i!! which may 20 be of either a spring or electric type, and which is geared to a vertical center shaft it to provide a constant speed rotation of said shaft in synchronism with time, whereby said shaft will make one complete revolution in a desired period or 25 cycle of operation. For the present purpose of disclosure and desirably where the apparatus is adapted for use in pre-selection in radio programs, the shaft is geared to the motor to rotate one complete revolution in one Week. Car- 30 ried by the shaft lli for rotation therewith is an arm l'l which is positioned intermediate the walls Il and I2 and adjacent to and spaced from the wall l2, and is adapted to rotate with the shaft with a plane substantially parallel to the 35 wall l2. Mounted on the arm V! adjacent the outer end thereof is a member i8, which is provided with a part lil movable vertically with respect to the arm il and to and from the wall l2. Carried on the part lll of the member IS are a 40 plurality of switch Contact members 2i which are spaced radially from each other relative to the arm. A second set of contact members 22 are supported by means of spring arms 23 carried on an upstanding part 24 of the arm l1 45 directly over the contact members 2l (see Figure 5). Mounted between the contact members 2l and 22 but insulated therefrom by means of washers 2!) and resiliently resisting their engagement is a helical spring 25 which normally holds 50 the contact members apart, even when the part I9 of the member I8 is raised in the direction of the contact member 22. To produce a contact between the lower contact member 2! with the upper contact member 22, I provide for the 55 mounting in the plate I2 of a plurality of pins 21, the lower end 28 of which extends into proximity to the upper contact member 22 and engages this member upon vertical movement of the part I9, so as to stop the upward movement of the contact member 22 and enable engagement thereof by the contact member 2l. In accordance with the present construction, a vertical movement of the part I9 of the member I8 is effected by pivoting the member I8 to the arm I1 and arranging the part IS at one end of the member I8. Vertical movement of the part is produced by means of an electro-magnetic device 2S carried by the arm and including an electric coil 3I on the arm and a magnetic-plunger 32 secured to the opposite end 33 of the member I8, whereby upon energizing of the coil 3l, the end 33 of the member will be rocked about its pivotal connection to the arm to displace the opposite end I9 of the member upwardly towards the upper set of contact members 22.

In accordance with the above described arrangement, each pair of contact members 2 I and 22 are spaced radially from the other pairs of contact members, so that upon rotation of the arm I1, the pairs of contact members will pass around circular concentric paths or courses of movement. In conformity with this arrangement, I provide in the wall I2 overlying the arm `I1 a plurality of openings 34 for the receipt of the pins 21 aforesaid and which openings are arranged in concentric sets aligned with the concentric paths of the contact members and spaced circumferentially at predetermined distances in each'set of openings. Where the apparatus is adapted for use with a radio receiver in effecting the selection of programs which frequently change at fteen-minute intervals, the openings 34 in each set are spaced from each other circumferentially by a distance equivalent to the travel of the arm I1 during the period of fifteen minutes. Suitable indicia 35 (see Figures 2 and 7) are preferably mounted on the upper side of the wall IZ for indicating the several rings or Sets of openings and the time interval spacing between openings in each ring. In this manner, one pin 21 may be placed in one of the sets of openings at each time interval to engage and operate the electric switch contact raised into engagement therewith. A cover plate I3 is preferably mounted over the top of the pins 21 to prevent the raising of thepins away from the contact members. An arm 31 may be mounted on the upper end of shaft I6 for indicating the time of day and also the position of the arm I1 underlying the wall'IZ. Means for energizing the electro-magnetic device 29 for raising the switch contact members at predetermined time intervals as above described, is here effected by means of a rotary electric switch 38 connected to the motor I4 and having a rotary switch arm v39 .and a plurality of cir'- cumferentially spaced contacts 4| which are engaged by the arm at predetermined time intervals, for example, fifteen minutes. The 'contacts il are here connected together by an annular conductor 42, and the latter is electrically connected to one side of the coil 3l by means of a conductor A3. The other side of coil 3i is connected to one side of a source of electric potential M by means of a conductor 46V, lwhile the other side of the source is connected by conductor lll' to the switch arm 39. In the apparatus the connections to the coil 3A! are made through a pair of

sliprings

48 and 49 on the shaft I6 and stationary brushes 5| and 52 on the support.

Contacting members 2l and 22 may be connected to any external electric circuit for operation thereof in a time controlled manner provided by the foregoing mechanism. As here shown, a plurality of electro-magnetic actuators 53 are connected in an electric circuit (see Figure 6) with the contact members 2l and 22 and a source of electric potential 555, and the magnetic actuators 53 are mounted in operating relation to a set of push-buttons 53, such as used in a radio receiver for selecting various broadcast programs and for turning the receiver on and off. These actuators 53 are connected to the rotating switch contact members 2l and 22 by means of a plurality of slip-rings 5l and brushes 58 carried by the shaft and support respectively. In the present embodiment, the slip-rings 51 as well as slip-rings IIS and le aforementioned, are formed as fiat annular rings carried by a disc 5e of electric insulation material, on the shaft I6 while the

brushes

53 and 5I and 52 are supported on a stationary arm tl carried by the support wall II. The contact members 2l are connected in common by the member I9 which is electrically connected to the shaft IE by members I8 and Il. This connection is shown as conductor e2 and the shaft and bearing as slip-ring and brush respectively in Figure 6. A conductor 63 is connected to a bearing 64 (see Figure 1 and shown as brush in Figure 6) for the shaft v and to one side of the source of potential 54. The other side of the source of potential is connected by conductor e6 to a common side 65 of all of the actuators 5,3. The other sides of the actuators are connected by a plurality of conductors 62 (shown as arrows in Figure l) to the several brushes 5 8. The slipfrings 5i are connected by conductors 51 to the contact members Z2 to eemplete the electric circuit.
