4 Claims; 4 Drawing Figures BINARY CLOCK BACKGROUND OF THE INVENTION Many time measuring devices are available on the market today. Because of the number of such devices available, there has been a tendency to standardize same as to the arrangement of the time readout provisions thereof. One such arrangement is the dial clock with the numbers thereon arranged in a circle about the dial and another arrangement uses a numerical display.

A Because of the standardization of such time measuring devices, bery little artistic uniqueness could be offered to the potential customer for such devics. Moreover, no provision was made with these prior art devices which allowed only the owner to determine the correct time when the time measuring device was visible to other persons.

SUMMARY OF THE INVENTION These and other problems and disadvantages associated with prior art time measuring devices are overnumbering system of l-12, a second ordered array of light sources corresponding to a binary numbering system of 1-12, and time control means for selectively illuminating selected lingt sources to indicate the hour 'and for illuminating selected light sources to indicate the minute interval past the hour. A third array of light sources corresponding to the numbers 1-4 may be provided and illuminated selectively by the time control means to indicate the particular minute within the particular 5 minute interval indicated by the second array of lights. Each of the arrays has four light sources therein.

The method of the invention includes the steps of illuminating a first ordered array of light sources to indicate the hour of the day using a binary numbering system and of illuminating a second ordered array of light sources to indicate the 5 minute interval of the hour of the day. The method may also include the step of illuminating a third ordered array of light sources to indicate the minute within the particular five minute interval indicated by the second array.

These and other features and advantages of the invention disclosed herein will be more fully understood upon consideration of the following detailed description and accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views and in which:

BRIEF DESCRIPTION OF THE DRAWINGS light array patterns; and,

FIG. 4 is an electrical schematic drawing of the time control circuit of the invention.

These figures and the following detailed description illustrate specific embodiments of the invention, however, the inventive concept is not limited thereto since it may be embodied in other forms.

7 DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS Referring to FIG. 3, the invention includes generally a first array of light sources 11, a second array 12 of light sources 11, a third array14 of light sources 11, and a time control means for selectively illuminating the light sources 11 in each array.

There arefour light sources 11 in the first array 10 and are arranged to correspond to a binary numbering system of 1-12. Thus, the sources 11 in array 10 correspond to the values 1, 2 4 and 8 as indicat ed light sources 11 disclosed are conventional light bulbs, other types of light sources may be used. Likewise the second array 12 has four light sources 11 that correspond to l, 2, 4, and 8 as indicated on P-2 form a circle with sources 11 equally spaced therealong. To facilitate reading the display by the light sources 11, each array 10 and 12 is ordered so that the value of each light source 11 in array 10 increases from the right when reading clockwise in FIG. 3 and the value of each light source 11 in array 12 increases from the right when reading counterclockwise in FIG. 3. The light sources 11 in the array 14 are also ordered with the value of each increasing from the right lower corner and moving counterclockwise as seen in FIG. 3. It will also be noted that the array 14 is arranged in a square about the arrays 10 and 12.

In illustrating the operation of the invention, the time control circuit 15 illuminates the appropriate light sources 11 in array 10 to indicate the hour, the light sources 11 in array 12 to indicate the 5 minute interval past the hour, and the light sources 1 1 in array 14 to indicate the minute within the 5 minute interval shown by array 12. For example, to indicate 3:21, the 2 and l value light sources 1 1 in array 10 would bee illuminated to give a total value of three; the 4 value light source 11 in array 12 would be illuminated to indicate the fourth 5 minute interval past the hour or 20 minutes past the hour; and the l value light source 1 1 in array 14 would be illuminated to indicate 1 minute within the 5 minute interval to give a total reading 3:21. To indicate 10:32, the 8 and 2 value light sources 11 in array 10, the 4 and 2 value light sources 11 in array 12, and the l and 2 value light sources in array 14 would be illuminated.

Referring now to FIGS. 1 and 2, it will be seen that the arrays 10, 12 and 14 are carried by a housing 20 having a generally square configuration. Housing 20 includes a pair of parallel vertical side members 21 joined at their their ends by a top member 22 and a bottom member 24 to provide an open square frame. The

inside edges 25 of members 21, 22 and 24 are provided with aligned rear recesses 26 parallel to and spaced inwardly of the rear edges 28 of members 21, 22 and 24. Front recesses 29 are provided on the inside edges 25 parallel to recesses 26 and spaced forwardly thereof by a distance a.

A light mounting board 30 is carried in rear recesses 26 and mounts the light sources 11 on the front surface 31 thereof in the aforementioned arrays 10, 12 and 14. A masking member 32 is carried in front recesses 29 over the light sources 1 1 with the distance a being sufficient to position member 32 sufficiently forward of board 30 to clear the light sources 11.

The masking member 32 is constructed of a translucent sheet material effective to substantially prevent the viewer from seeing light sources 11 until they are illuminated. Any of a number of materials may be used for same, however, a commercially available smoked plastic sheet has been found satisfactory.

The front surface 31 of board 30 and those portions of the inside edges 25 of members 21, 22 and 24 may be painted a dark, light absorbing color or coated with a light absorbing material 34 as seen in FIG. 2 to insure that the light sources 11 are not seen until illuminated.

CONTROL CIRCUIT While various control circuits may be used to operate the invention, the circuit shown in FIG. 4 illustrates an electromechanical version. As seen in the schematic, the minute array 14 of light sources 11 are controlled through a stepping relay R1, the minute array 12 of light sources 11 are controlled through the stepping relay R2, and the hour array of light sources 11 are controlled through the stepping relay R3. Relay R1 is is a 5 pole, 6 position stepping relay and relays R2 and R3 are 5 pole, 13 position stepping relays. The poles of relay R1 are numbered Rl-l through R1-5 and the positions numbered 1-6. The positions and poles of relays R2 and R3 are likewise numbered. Each of the relays R1, R2 and R3 have a stepping coil for operating the movable contact of each pole through the positions and a release coil for returning the movable contacts to position l. A normally closed set of contacts are operated by each stepping coil. The stepping coils are referenced Rl-S, R2-S, and R3-S, the release coils Rl-R, R2-R and R3R, and the associated contacts Rl-R, R2-R,

'and R3-R.

As seen in FIG. 4, one side of the 1 light 11 of array 14 is connected to the movable contact of pole Rl-l, one side of the 2 light 11 to the movable contact of pole R1-2, one side of the 3 light 11 to the movable contact of pole R1-3, and one side of the 4 light 11 to the movable contact of pole R1-4. The movable contact of pole Rl-S is connected to ground through normally closed contacts R1R,. The fixed contact at positions l-4 of pole Rl-l, at positions 2-4 of pole Rl-2, at positions 3 and 4 of pole Rl-3 and at position 4 of pole R1-4 are also connected to ground through contacts R1R,. The fixed contact at position 5 of pole Rl-S is connected to relay R2 as will be explained and the fixed contact at position 6 of pole Rl-S is connected to one side of release coil Rl-R.

The relays R1, R2 and R3 are driven by a 1 rpm synchronous motor M1 connected to a conventional 115 volt AC power source. A set of contacts Ml-l are associated with motor M1 which causes the contacts Ml-l to be closed momentarily on each revolution of motor M1. A power supply circuit 40 is connected to the H5 volt AC power source through a transformer T, having a first output winding W and a second output winding W The first output winding W 1 is connected to a rectifier circuit 41 having a diode D,, a resistor R and a capacitor C,. The hot output A of circuit 41 is connected to the hot sides of each of the stepping coils and release coils of relays R1, R2 and R3 and is shown as 48 volts DC. The second winding W is connected to one side of each of the lights 11 in arrays 10, 12 and 14.

The ground side of stepping coil Rl-S is connected to ground through a normally closed set mode toggle switch SW-SM and contacts Ml-l of motor M1. The ground side of coil Rl-S is also connected to ground through normally open pushbutton set switch SW-S.

The 1", 2, 4 and 8 value light 11 of the 5 minute array 12 are connected respectively to the movable contacts of poles R2-l, R2-2, R2-3 and R2-4 of relay R2 with the movable contact of pole R2-5 connected to ground through normally closed contacts R2R The fixed contacts at positions 1, 3, 5, 7, 9 and 11 of pole R2-l; at positions 2, 3, 6, 7, 10 and 11 of pole R2-2; at positions 811 of pole R2-4 are also connected to ground through contacts R2R The fixed contact at position 12 of pole R2-5 is connected to relay R3 as will be explained and the fixed contact at position 13 of pole R2-5 is connected to the ground side of the release coil R2-R. The ground side of the stepping coil R2-S is connected to the fixed contact at position 5 of pole Rl-S of relay R1 through the normally closed set mode toggle switch SW-SM and is also connected to ground through the normally open set pushbutton switch SWS The l 2, 4 and 8 value lights 11 of the hour array 10 are connected respectively to the movable contacts of poles R3-1, R3-2, R3-3 and R3-4 with the movable contacts of pole R3-5 connected to ground through the normally closed contacts R3R,. The fixed contacts at positions 1, 3, 5, 7, 9 and 11 of pole R3-l; at positions 2, 3, 6, 7, 10 and 11 of pole R3-2; at positions 4-7 and 12 of pole R3-3; and at positione 8-12 of pole R3-4 are also connected to ground through contacts R3-R The fixed contact at position 13 of pole R3-5 is connected to the ground side of release coil R3-R. The ground side of stepping coil R3-S is connected to the fixed contact at position 12 of pole R3-5 of relay R2 through the normally closed set mode toggle switch SWSM and also to ground through the normally open set pushbutton switch SWS In operation, the relay R is stepped one position each time motor M1 closes contacts Ml-l. This causes the appropriate lights 11 of the array 14 to be illuminated to indicate the minute in each 5 minute interval. Once the light 11 is illuminated, it remains illuminated for the remainder of the 5 minute interval. When relay R1 is stepped to position 5, it causes relay R2 to step one position to indicate the next 5 minute interval. When relay R1 is stepped to position 6, the release coil Rl-R is energized to return the movable contacts to their original start position. Likewise when relay R2 is stepped to position 12, the relay R3 is stepped one position to indicate the next hour interval and when it is stepped to position- 13, it is reset. When relay R3 is stepped to position 13, it is likewise reset.

To set the clock, set mode switches SW-SM,, SW-SM and SW-SM are opened to prevent automatic operation of relays R1, R2 and R3. Then set switches SWS SW-S and SWS are manually operated to independently step relays R1, R2 and R3 to the desired position. Set mode switches SWSM SW-SM and SWSM are then closed so that motor M1 again controls the operation of the relays.

While specific embodiments of the invention have been disclosed herein, it is to be understood that full use may be made of modifications, substitutions and equivalents without departing from the scope of the inventive concept.
