ELECTRICAL SCOREBOARD 'Filed July 9, 1940 '2 Sheets-Shee'rl 2 'z ATTORNEYS Patented Jan. 5, 1943 UNITED STATES PATENT *OFFICE ELECTRICAL sooREBoARn John C. Vian, Lebanon, Ohio Application July 9, 1940, serial No. 344,553
3 Claims.
This invention relates to an electrical scoreboard or indicator for displaying numbers or signals. The invention also is directed to an electrical circuit arrangement for selecting and controlling the display of the numbers or signals from a remote location.
While devices of this general type have been available in the past, the principal object of the present invention has been to provide separate portable interchangeable units each capable of displaying a number from to 9. Each such portable unit is provided with an independent switch circuit and control therefor and the units therefore may be arranged in patterns or groups determined in accordance with the nature of the information or signal to be exhibited. For example, the devices are intended to be utilized by high schools and colleges for scoring athletic events, the individual units being grouped in one suitable arrangement for displaying football scores, in another arrangement for basketball and still another for scoring track events or other sports. Being portable, the group of units is transported to the playing field at the time of the event, then stored until next needed. This feature is of considerable practical importance. A Conventional scoreboard of the type heretofore employed is costly and elaborate; so expensive in fact, by virtue of the necessity for weatherproofing the housing for the apparatus, that many high 'schools and even colleges do not have the funds necessary for facilities. The present units are individually and collectively inexpensive and therefore have already found extensive usage.
The object of the invention also has been to provide scoring units in which the signals are displayed by means of prearranged groupings of incandescent lamps. The lamps are energized through a circuit arrangement, and the illumination of them in ,predetermined figuregrams or patterns is controlled by the manipulation of switches on a simple panelboard.
A further objection of the invention has been to provide a circuit for selecting and controlling the display of signals in a simple and efficient manner. In this respect, the invention contemplates a circuit including a switch for each digit to be displayed upon the panelboard; the switches, for example, are marked 1 to 0. If a 5 is to be displayed then the switch corresponding to the digit 5 on the panelboard is actuated and if next a '7 is to be displayed this switch is likewise operated after 5 is turned to its initial position.
Other objects and features of the invention 'control is a subtractive one.
will be apparent from the following description of the typical embodiment of the invention which is illustrated in the drawings.
In the drawings:
Figure 1 is a circuit diagram showing the interconnection of the group of lights in the display unit with the group of controlled switches on the panelboard. s
Figure 2 is a diagram illustrating the switchboard. l
Figures 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 illustrate respectively the lamps of the group which are energized in the delineation of the flgures 1, 2, 3, 4, 5, 6, '7, 8, 9 and 0.
Figure 13 is a cross sectional view showing Ithe construction of one of the portable units.
As previously described the lamps of each portable signal unit are arranged in a group or bank and predetermined members of this group or bank are energized for the display of the signals. The lamps of the group or bank are arranged in the form of a horizontally extending rectangle with a row of lamps extending across this horizontal rectangle approximately intermediate the top and bottom rows of lamps. For convenience the pattern of the lamps may be described as a rectangular figure 8. In the preferred embodiment there are eighteen lamps.
The next feature of the invention which is of importance in obtaining a simple switching circuit is predicated upon the concept of selectively deenergizing selected groups of lamps from the total number for the display of signals other than the figure 8. Otherwise expressed, at the beginning of each signalling period all of the lamps are energized and an 8 figuregram is displayed. The successive groups of lamps are deenergized upon actuation of the respective switches other than the 8 switch so that the process of the In the past it has been proposed to use a plurality of switches for controlling a plurality of lamps in certain groupings but, each switch was employed for making a circuit to a certain group of lamps forming a letter independently of each other switch and circuit. The complexity of such an arrangement is avoided in the present apparatus.
The scoring unit which is illustrated in the drawings comprises a controlling circuit which is housed in a portable box 12, a panel circuit [3 of eighteen lights arranged in the form of a rectangular figure eight and a ten-Wire conducting cable |4 `,which interconnects the control circuit and the panel circuit. A two-Wire cable l5, having a plug IS at its one end for quick attachment into the control circuit ll, provides operating current for the unit. The ten-Wire conducting cable l4 has a ten-point plug l1 for making connection into the control circuit. Cable M also may have a ten-point plug at its other end (not shown) for connection into the panel circuit l3. A handle l8 is provided for the box which houses the control circuit so that it may be transported easily.
The control circuit is operated through eleven toggle switches. Ten of the toggle switches control the signals which appear on the light panel. For the sake of convenience, those are indicated on the drawings by the digits which they control, that is, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. The other toggle switch l is a master switch and breaks the entire circuit from the source of current. The Operating levers or handles for switches l to 0 and l 0 are I' to 0' and l0' respectively.
Referring to Figure l of the drawings, toggle l is a double pole switch and its two poles are indicated by the numbers la and lb. The dotted line interconnecting la and lb represents a cornmon Operating mechanism which is actuated by the switch lever l'. Toggle 2 is also a double pole switch having poles Za and 2b. Similarly, toggle 3 has poles 3a and 3b. The dotted lines interconnecting poles 2a and 2b and 3a and 819 respectively represent common Operating mechanisms for these double pole switches which respectively are operated by the switch handles 2' and 8'. Toggle 4 is a single pole switch and, for clarity, its pole will also be indicated by 4. Toggle 5 is a double switch having poles 5a and 51), interconnected by a common Operating mechanism represented by the dotted line and controlled by the switch handle 5'. Toggle 6 is a single pole switch and its pole is indioated at 6. Toggle 1 is a double pole switch having poles 1a and 1b, which are interconnected by the common Operating mechanism shown by the dotted line which in turn is controlled by the switch handle 1'. Since the digit 8 is formed when all of the 18 lights of the panel are on, toggle 8 is a dead switch having no connection in the circuit. The toggle is provided so that no confusion arises from its absence, in the case of a novice operater. Toggles 9 and 0 are both single pole switches, their poles being inclicated, respectively, by 9 and 0.
In Figure 1 the circuit at the left is the control circuit l l. The box-like figure between the two circuits, indicated at l9, represents the tenwire conducting cable M with its two plugs. The circuit at the right represents the panel circuit with its lights. For identifioation the ten lead wires in the conducting cable are numbered 20, 2l, 22, 23, 24, 25, 28, 21, 28, and 29,1ead 29 being the common return. The lights on the panel are numbered, starting at the top left 30, 3l, 32, 33, 34, 35, 36, 31, 30, 39, 40, 4l, 42, 43, 44, 45, 46, and 41, respectively.
The switches in the circuit are arranged to break the contacts to those lights that are not a part of the desired digit signal. In other words, the double pole switch operated by the handle l' controls the formation of digit 1, this switch thus breaks the circuit to all rights except those necessary to form a figure 1. So, when all digit switches are off, and the master switch is on, the digit 8 will be shown.
In the control circuit a lead 48 from the source of power divides at point 49 into leads 50 and 5l which go to poles l0a and lllb of toggle switch `l0 respectively. The other lead from the source of power extends through to the common lead or wire 29 of the ten-Wire conducting cable l4 and for simplicity will bear its reference character 29.
Now tracing the leads from pole la to the tenwire conducting cable M, a lead 52, from pole l0a, divides at point 53, one lead 54 going to pole la of toggle l and the other 55 going to dividing point 56. Two leads 51 and 58 extend from point 56.
From pole la, a lead 58 divides at point 60; one lead 6l going to pole 1a and the other, being Wire 20 of the ten wire conductor, goes to the cable M, as represented by the box l9. A lead 02 from pole 1a divides at point 63 into leads 64 and 65, lead 84 going to pole 0. From pole 0 the wire 2l extends to the cable M. Lead 65 connects point 63 to pole 2a. The other side of pole Za is connected to pole Sa by a lead 80. Wire 22 of the cable M extends from the other side of pole Sa.
From point 58, the two leads 51 and 58 go to poles 2b and Sa, respectively. The other side of pole 2b is connected to Wire 23 of the ten-wire conducting cable M while a lead 61 extends from the other side of pole 5a to connect it to pole 6. The other side of pole 5 is connected to Wire 24 of cable M.
From pole lllb of switch l0 a lead 68 extends to a point 69. Point 69 is connected through a lead 10 to pole lbV on the one side and on the other side to the cable M through Wire 28. From pole lb a lead 1l extends to pole 4 which is conneoted at its other side by a lead 12 to a dividing point 13. One lead from point 13 is the wire 21 of the cable M, the other is a lead 14 which connects it to pole 'i'b of switch 1. A lead 15, from the other side of the pole 1b goes to a point 16 where it divides into a lead 11 and Wire 26 of cable M. Lead 11 extends from point 16 to pole 3b. Pole 31) is connected to pole 5b by a lead 18 and pole 51) is connected to pole 9 by a lead 19. The other side of the pole 9 is connected to Wire 25 of the ten-Wire conducting cable.
In the diagram of the circuit of the panel lights (Figure 1) two lines and 8l, running parallel to each other, are in connection with the common return Wire 29 through leads 82 and 83 respectively. For identifioation, the joint between leads 80 and 82 will be numbered 84 and the joint between leads 8l and 83 will be numbered 85. The point where leads 82 and 88 join return 29 will be numbered 88.
Two lines 81 and 88 joined at point 89 connect the other ends of parallel leads 80 and 8l as at points 90 and l-il, respectively. Light 3l is connected into line 81 and light 32 is connected into line 88. Between the two ends of the parallel lines two leads 92 and 93, joined at joint 94, are connected to the lines 80 and 8l at points 95 and 98, respectively.
All lights, with the exception of light 30, are connected in parallel circuits, light 30 being connected in series with Wire 20, through point 90, lead 80, point 84, lead 82 and point 86 to the common return wire 29.
Lights 33 and 41, the only two lights that are on for every digit, are in a parallel circuit from vlead 28. At point 91, on lead 28, a dividing lead 98 goes through light 33, point 9l, lead 8l to point 85. From point 91, lead 28 extends through light 41 to a point 99. From point 99 a lead l connects to point 85. From point 85 the parallel circuit for lights 33 and 41 is completed through lead 83, point 86, and return 29.
Panel lights 34 and 36 are connected across from Wire 22 to lead 80 and so to return 29 through point 84, lead 82 and point 86.
The circuit furnishing current to lights 38 and 39 comes through Wire 2I and divides at point 94 into leads 92 and 93 which go through lights 38 and 39 respectively to points 95 and 96, through the parallel leads 80 and 8! to points 84 and 85, leads 82 and 83 to join return 29 at point 86.
Lights 41 and 43 are connected across to lead 8| from Wire 23 to establish a circuit through point 85, lead 83 and point 86 to return 29.
In surmnary, Wire 20 controls light 30; Wire 2l controls lights 38 and 39; Wire 22 controls lights 34 and 36; Wire 23 controls lights 4l and 43; Wire 24 controls lights 35 and 31; Wire 25 controls lights 40 and 42; wire 26 controls lights 44, 45 and 46; Wire 21 controls lights 3l and 32; and Wire 28 controls lights 33 and 41. Wire 29 is common to all.
Figures 3 to 12, of the drawings, illustrate the digits 1 to 0, inclusive, and show, by heavier lines, which wires are energized to light each digit.
Operation As stated before, the circuit is arranged to turn out those lights which are not a part of the desired digit When the control toggle for that particular digit is thrown. The panel of lights, arranged in the form of a rectangular figure eight, provides all of the lights necessary to form any of the ten digits. By turning certain of the lights out, the operation can form any one of the digits at Will. It is to be observed that only one switch, With the exception of switch l0, is left manipulated at any time.
To deenergize those lights necessary to leave the digit 1 showing, the operator throws toggle l by Operating handle I' to break the controlling circuit at poles l a and lb. This cuts out wires 20, 2l, 22, 25, 26, and 21, breaking the circuit to lights 30, 3l, 32, 34, 36, 38, 39, 40, 42, 44, 45, 46, leaving lamps 33, 35, 31, 4l, 43 and 41 energized through wires 28, 24, 23 and 29 (Figure 3).
Digit 2 is lighted by Operating handle 2' to break the circuit at poles 2a and 2b. This deenergizes wires 22 and 23 cutting out lights 34, 36, 4l and 43 (Figure 4).
Digit 3 is formed by throwing handle 3' to cut out wires 22 and 25 at poles 3a and 3o, deenergizing lights 34, 36, 40 and 42 (Figure 5).
Digit 4 is lighted when wires 21, 25, and 26 are cut from the circuit by Operating handle 4' which breaks the current at pole 4 (Figure 6).
Digit 0 is formed when handle 0' isthrown to break the current to Wire 2l at. pole 0 and so to deenergize lights 38 and 39 (Figure 12).
