ULYSSES D. FOBTIER, OF TULSA, OKLLHOMA.

TIME-SWITCH.

Application filed June 13, 1916.

To all whom it may concern Be it known that I, ULYSSES D. Fon'rmn, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Time-Switches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in time switches and the principal object of the invention resides in the provision of a switch for automatically closing an electric circuit at a predetermined tlme.

Another object of the invention is to provide a device which may be adjusted to open the circuit at any predetermined moment after the same has been closed.

Another object of the invention resides in the provision of a time switch which is particularly adapted for controlling the lighting of lights in show windows on the eve of darkness and extinguishing the lights at a predetermined hour thus avoiding the necessity of employing manual labor for lighting and extinguishing the light.

A still further object of the invention is to provide a device for use in banks and the like where electrically controlled locks are used which are guarded by the train controlled mechanism thereby avoiding the possibility of opening a vault between cer-,

tam hours. Y

With these and other objects in View, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which 2- Figure 1 is a view partly in section of a switch constructed in accordance with this invention showing the same arranged to control an independent circuit. Fig. 2 is a face view of the dial of the clock used in connection with the device. Fig. 3 is an edge view of Fig.2. Fig. 4. is an enlarged detail view of the hour hand showing the contact arranged thereon. Fig. 5 is a detail perspective view of the plug used in connection with the device, and Fig. 6 illustrates the wiring diagram.

Referring to the drawings the numeral 1 designates the moving element of the switch Specification of Letters Patent.

comprising the sliding core 2 carrying the angular arm 3. This arm 3 has connected,

to its lower end the handle 4 of the main line controlling switch which comprises the blades 5 secured to the head 6 which head 1s supported on the end of the handle. The blades 5 are adapted to engage beneath the plates 7 forming the terminals of the main line wires 8 of an independent circuit and it will thus be seen that when the blades 5 engage the plates 7 the circuit will be completed through the main line wires.

In order to provide a means for moving the element 1, the solenoids 9 and 10 are provided with the contact springs which will be more fully hereinafter described The solenoids 9 and 10 are arranged in spaced relation as shown in Fig. 1 and are provided with openings in alinement for the reception of the sliding core 2 so that when either is energized the core will be moved. The contact springs carried by the solenoid 9 are designated by the numerals 11 and 12 and are arranged so their free ends designated by the numeral 18 normally tend, to move toward each other. When the armature 2 is attracted by the solenoid 9 it will be seen that the fibrous strip designated by the numeral 14 carried at one end of the armature or core will pass between the springs 11 and 12 thereby discontinuing the circuit through the solenoid 9. A similar fiber strip 15 is carried at the opposite end of the core 2 and is adapted for separating the contact strips or springs 16 and 17 carried on the end of the solenoid 10 and it will thus be seen that when the solenoid 10 is energized the strip will move into the position shown in Fig. 1 thereby breaking thecontact and discontinuing the flow of current therethrough.

The clock used in connectionwith the device is designated by the numeral 18 and may be of any suitable construction and this clock is provided with the usual face 19 over which the minute and hour hands designated by the numerals 20 and 21 respectively travelu Suitable contact members 22 are arranged around the dial or face 19 and are adapted to be engaged by the contactarm carried by the hour hand which will be more fully hereinafter described. These contact points QQ-are supported on a suitable insulating strip 23 so that they are independent of each other. The hour hand of the clock is best illustrated in Fig. and has pivoted thereto the contact arm 24 the end of which is bent as at 25 to engage the contacts 22 and a spring 26 is secured to the pivoted end of the contact arm and to the hub. of the hour hand so that the arm will be permitted a slight pivotal movement with relation to the hour hand and yet will return to its original position. It will be understood that the end 25 has a wedging contact with the contact 22 thereby insuring the proper operation of the device and avoiding the possibility of the burning of the contact.

In order that the hour at which the switch is to be operated may be varied to suit varying requirements a suitable switch board'is provided which carries one set of arcuate contact plates designated by the numeral 27 and a second set of such plates designated by the numeral 28. These contact plates 27 and 28 are arranged in pairs so that when the plug best illustrated in Fig. 5 and designated by the numeral 29 is inserted between any pair of plates the said plates will be in electric contact.

Referring to the wiring diagram, the battery used in connection with the device is designated by the numeral 39 and one terminal of said battery is connected by a wire 31 to the pivot point of the hour hand 21. The opposite terminal of'the battery is connected to the distributing wire 32 which is connected by a wire 33 to both of the contact springs 12 and 17 of the switch. The

- contact springs 11 and 16 are connected to their respective coils 9 and 10. The coil 9 is connected by means of a wire 34 to the wire 35 which in turn is connected to the upper plates of the lower set of contacts 28. The lower plates of the lower set of contacts are connected by individual wires designated by the numeral 36 to the wires 37 which lead from the contacts 22 to the upper contact plates of the upper set 27. lhe lower contact plates of the upper set 27 are connected through a wire 38 to the coil 10 and it will thus be seen that when the plug 29 is inserted between any two of the plates of the sets 27 and 28 and the contact arm'2d engages the contact 22 to which the plate receiving the plug 29 is connected it will be seen that the current will flow from the battery through the wire 32 and thence through the wire 33 from whence it will pass through one or the other of the coils according to the position of the plug 29 and thence through the switch into one of the wires 36 and the clock back to the battery. It will thus be seen that one or the other of the coils will be energized.- In event that the armature is standlng in the position shown in Fig. 6 and the plug 29 is in theposition illustrated in the same figure, it will be seen that the right hand coil designated by the numeral 10 will be energized since the contact springs 16 and through said solenoids,

integer 17 will be in electrical communication. Thus it will be seen thatthe switch blades 5 in Fig. 6 namely so that the tongue 15 engages between the springs 16 and 17 and the plug 29 is positioned in the'lower set of contacts it will be seen that the springs 11 and 12 will be in electrical communication and upon establishing a circuit through the device as previously described it will be apparent that the coil9 will be energized thus moving the switch into closing position.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims.
