Referring generally to Fig. l, the tap or dispensing valve 22' is piped in theconventional Way to a barrel or other container (not shown) containing the beverage which is on draught at the dispensing nozzle 20. The tap includes a suitable dispensing valve'actuated by the control lever 2! which is pivotally connected to the dispensing valve 22. The tapZll'is supported in any suitable manner asby"'a" counter, fountain, or
.9 imsii 0) bar 23, and the control lever 2| is so biased by mechanism conventionally enclosed within the casing of' dispensingvalve 22; that when the tap is not in use the control" lever 21 tends to resume an upright position. One suitable mechanism for so "biasing' the control lever 21% is shown and describedii'i 'United States Letters Patent No. 2,034,420 granted to- Peter-M. Reiland et al. on March 17, 193,62 1When "control lever 2i once attains its normal position, the springwasher Hi9 tendsto retain the control-lever 2! in'such normal positionp'Thetap- 22 and itsassociated piping is grouhdedxat 98; v I
' The upper end of the control lever 2! is providedwith a male threaded shank 24 fromwhich the conventional form-of a detachable handle ordinarily employed has been'removed'and replaced by the illuminated handle embodying the construction of this invention.
Onefor'm of illuminated handle embodying my said invention is shown in Fig. 1. As shown in Fig. '1,' said handle includes a hollow head 3| made of any suitable translucent material, preferably a translucent'molded plastic.
'The handle 3| is provided with a Window 32 fashioned out of a suitable translucent material such as Bakelite, 'Luciteforthe like, the window 32 being sealed at 35- mm the hollow head; 3!, to prevent flllOiStllTe from entering the hollow handle."
At the time the display window 32 is fabricated, suitable advertisingmatter 33 is embedded in the display window 32-"so as to form an integral part of the Window."
The advertising matter ,33 may include the brand name of the beverage dispensed from the tap with'which the handle :3! is associated,lor-it may contain other advertising matter" if preferred; i
The handle 3| may include a threaded shank 3l'having one'o'r more internal keyways 35' (Fig. 4); fashioned to receive the-'positioningribs 35 of an'insulated'adapterES. The adapter 28 may .be iabricatedfrom any preferred kind of insulating material but an adapter molded out of a suitable plastic material is relatively cheap and gives good'res'ults:
' The adapter '28 which constitutes a detachable extension of' thehandle' 3i provides'a suitable holder for the lamp bulb All. The adapter 28 may bedetachably-attachedto the handle St in any preferred'manneras by means of athreaded ring 38 so fittedas to abut against the annular shoulder 29" formed a'tthe upper end of'the adapter28 so as to s'e'atthe handle 'Qlupon the adapter 28 when the female threaded ring 3% is screwed over the threads of the male threaded shank 67. The positioning ribs St register with the keyways 35 formed in shank of the handle 3! to insure that the handle 35 will be so positioned relative to the valve control lever 2!, as to correctly display the advertising mat er 33 carried by the window 32.
The adapter 28 may be designed to receive any conventional type of electric lamp bulb 40, such for example as a lamp bulb having a conventional miniature screw base 4|, in which case the adapter includes a lamp base holder 43 of the screw socket type and a central spring contact 39. The metal holder 43 is electrically connected by a suitable metallic strap to a contact pin 38 positioned in the outer wall of the adapter 28. The lower end of the adapter 25 is recessed said recess being female threaded to match with the male threaded stem 24 of the valve control lever 2|. When a ground return signal circuit is employed, a female threaded metal bushing 21 is seated in the recess at the lower end of the adapter, to establish electrical continuity for the ground return of the signal circuit through the valve control lever 25 to the ground connection 98 (Fig. 1). Electrical continuity may be establish-ed between the central stud 42 of the lamp bulb 46 (Fig. 1) and the metal bushing 27 in any preferred manner, as by means of a central spring contact 99 which constitutes a resilient central electrode for the central stud 42 of the lamp bulb 40. The lamp holder 43 and the contact pin 38 and their associated metallic strap, and the metal bushing 27 and its associated spring contact 39 may all be secured in place during the molding of the adapter 28. When a lamp bulb 49 is screwed into the adapter 28, electrical continuity is established from the contact pin 38, through lamp socket 43, the filament of the lamp bulb, and lamp stud 42, through central spring contact 39 and metal bushing 21, valve control lever 21 to ground at 98, thus establishing a part of the lamp signal circuit.
By molding the shell of the hollow head 3i relatively thick and the display window 32 relatively thin, the intensity of the light emitted through hollow head 3! may be substantially reduced and the intensity of the light emitted through the display window 32 and its advertising matter 33 materially increased.
The valve control lever 2| of the dispensing valve 22 is biased in such a manner that when released it normally tends to assume a vertical position against the counter, fountain, or bar 23. A contact switch 58 which includes a plastic housing is mounted upon the counter 23 at the proper height to register with the contact pin 38 whenever control lever 2| returns to its normal upright position.
A rod 45 carrying a contact point 44 is slidably supported in the plastic housing of contact switch 50 in such a mannerthat the contact point 44 establishes electrical contact with the contact pin 38 whenever the valve control lever 25 returns to its normal position.
Referring to Figs. 2 and 3, the rod 45 may be made of any suitable insulating material such as molded plastic. The rod may be hollow to form a sleeve covering for the stem of the contact point 44. A continuity spring 48 establishes electric continuity between the stem of contact point 44 and a contact plate 49 located within the plastic housing of contact switch 50.
The plastic rod 45 slides into the plastic housing of contact switch 59 against increased tension exerted by the continuity spring 48, thus providing a suitable follow between the contact point 44 and the contact pin 38 of the adapter 28 whenever valve control lever 21 approaches or moves 01f normal. This follow of contact point 44 insures electrical continuity between the contact pin 38 and the contact plate 49 of contact switch 50.
The plastic rod 45 is provided with an annular groove 46 adapted to receive a locking pin 41 (Figs. 1 and 2) which is slidably mounted in the plastic housing of contact switch 56. Thus when the barrel piped to the dispensing valve 22 is empty, the attendant may push the plastic rod 45 into the housing of the contact switch 50 until the pin 41 engages the annular groove 46 thus holding the contact point 44 out of electrical contact with contact pin 38 to break the signal circuit and extinguish the lamp bulb 40, as a visible indication that the barrel piped to the dispensing valve 22 is empty. After the empty barrel has been replaced with a full barrel piped to the dispensing valve 22, the locking pin 41 may be withdrawn from the annular groove 45, thus permitting the continuity spring 48 to push the plastic rod 45 outwards and re-establish the signal circuit for the lamp bulb 4!] at contact pin 38, thus relighting the lamp 40 as a visible indication that the beverage is now on draught at the dispensing valve 22.
The plastic housing of contact switch 50 may be provided with a vent 5! (Fig. 1) to permit the escape of any moisture which may accumulate inside the housing 50.
The contact plate 49 is located within the plastic housing of contact switch 50. It may be connected to a suitable source of low voltage in any preferred manner as for example, to the low voltage secondary winding 56 of an iron core step-down transformer (Fig. 1), whose primary winding 55 may be connected in the conventional way to a suitable source of alternating current voltage 51. One side of the secondary winding 56 is electrically connected to the contact plate 49 over the low voltage supply lead 60, and the other side of the secondary winding 56 is connected through a fuse 58 to ground at 59. The ground side of the secondary winding 56 of the transformer is fused at 58 so that any overload current will blow the fuse 58 and completely open the signal circuit through the low voltage secondary winding 56.
The signal circuit is preferably wired through a moisture-proofed prewired connector strip 54, consisting of one or more hollow conductors or tubular wires 53 embedded in the connector strip 54, preferably by molding the material while in a plastic condition. Where two or more tubular wires 53 are molded in the connector strip 54, they are retained in parallel spaced relationship at a suflicient distance apart, so that the insulating material from which the connector strip 54 is molded enters in between the tubular wires 53 and completely insulates the tubular wires from each other and protectsthem against external exposure.
The connector strips 54 (Fig. 2) are made in suitable lengths so that they can be laid in end to end abutment to construct a signal circuit of any desired length.
Electrical continuity is established between the adjoining sections of tubular wiring by inserting a double ended tapered pin 52-52 (Fig. 3) in the adjoining ends of the tube wiringthus bridging the conductors of the adjoining sections oi tube wiring together. The diameter of each end of the double ended tapered pin 52-52 is such as to cause each tapeed pin 52 to frictionally engage the inner wall or" the tube wiring 53 and establish perfect electrical continuity.
One suitable form of double ended tapered pin is shown in association with the contact plate 49 of the pies is housing 58 (Fig. 3). The connector strips 5 l5 i (Fig. 3) are terminated in spaced relation so as to receive the plastic housing The tapered pins 5252 (Fig. 3; extend in opposite directions from th contact plate into the oppositely disposed spaced connector strip sections fi l-iii} or" the hollow tube wiring 53-53, so that each tapered pin 52 irictionally engages the inner wall of a section of tubing thus establishing electrical continuity between the contact plate 4i, and each section of tube wiring 53, while at the same time forming a bridge connection between the spaced tubular wires 53-53. Any desired number of sections of connector strip 5 5 may be electrically interconnected by means of the double ended tapered pins 52--52 associated with each contact plate 29 of each outlet unit til.
Since the connector strips as are made of plastic material, they may be readily cut (as by sawing) into shorter lengths of any required size, to facilitate the installation of any desired wiring system having required number of outlets for use in conjunction with any desired arrangement of dispensing valves 22 42.
A metallic signal circuit may be employed to replace the grounded signal circuit. When a metallic signal circuit is employed, the grounded connections 5%} and 88 (Fig. 1) may be replaced by an insulated metallic conductor similar to the conductor Ell (Fig. i). A metallic signalling tern employs a connector strip or molding .r to the molding 5 but having two conductors embedded in the connector strip in parallel spaced relation instead of the single conductor 53 shown in Figs. 2 and 3 of the drawings. A connector sti'p containing twin tube wiring is shown generaiy in Figs. 8 and 8a, wherein the connector strip 86 contains two tubular conductors and iii which are bridged to the twin conductors the adjoining section of connector strip by means of the tapered pins 5? and (Fig. '80.). Where twin tubular wiring is ernployed, the plastic housing of the contact switch H contains a slidably mounted contact rod l2 carrying the separately insulated contact pins '53 and i i. Each contact pin 73 and i5. is retained in electrical continuity with its associated contact plate I95! or if}? by means of its continuity spring fill or NH. Contact plate its is in electrical continuity with tapered pin 52, while contact plate 192 is in electrical continuity with tapered pin 53, so that the contact pins 2'3 and 74 may constitute a T connection 01' tap-cit from the twin tubular wiring 58 and it of the signal system.
When a metallic circuit is employed for the signalling system, the insulated adapter iii 5, 6, and '7) is provided with twin insulated co. tact pins 63 and .64 adapted to register with the twin contact pins l3 and M of the contact switc': ll. Insulated adapter 63 (Figs. 5, 6, 7) s provided with one or more posi ioning ribs which function in the same manner as the positioning ribs 33-436 of insulated adapter 23 (Fig. 4). Thecontact pins 63 and 54 of the adapter 6! .are in electrical continuity with the screw socket 8i and with the center spring contact 83 of the adapter. As best illustrated in Fig. 5, the center spring contact 33 is connected to the contact pin by means of the metal strap 82, and the screw socket holder Si is connected to the contact pin '63 by a metal strip 84. The lamp bulb 65 (Fig. 7) which may be of the miniature type is provided with a miniature screw base adapted to be screwed into the screw socket holder 8% so that the screw base of lamp bulb is in electrical continuity with screw socket 8i, and the central stud of lamp bulb 65 is in electrical continuity with center spring contact thus establishing a completely insulated metallic circuit through the filament of the lamp bulb 65.
The hollow head is is provided with a window it suitably sealed in the head 76. Suit-able advertising matter is is displayed in the window ii, the advertising matter 13 preferably forming an integral part of the window 5?. The shank of the hollow head 75 may be undercut male threaded at "E9 to interengage the female threads of the threaded ring 88. The ring 82 is provided with an inwardly projecting flange which on gages the annular shoulder 97 of the adapter thus locking the hollow head it to the adapter BI, in the manner previously described.
The lower end of the adapter El is recessed, and to facilitate direct or indirect attachment to the valve control lever 21 the recessed lower end or" the insulated adapter 6| may be female threaded as indicated at 85.
The conventional valve control levers 21 may be provided with male threaded shanks '24 of various sizes and threads, so that the insulated adapter El must be provided with suitable means for attaching the insulated adapter Bl to any valve-control lever 2i regardless of the size or character of the thread of the male threaded shank 24. This may be accomplished by providing a reducer 25 having a male threaded end v2 3 adapted to threadably engage the female threaded socket 85 of the adapter 6!, and a female socket Hi3 adapted to engage the male threaded shank 24 of valve control lever 2|. ,A knurled locking washer 15 may be inserted upon the male threaded shank 24 to insure correct centering of the hollow head 3-5 upon the valve control lever 2| so as to face the window i] in the proper direction to correctly display the advertising matter 18.
Fig. 9 shows the invention applied to the tap of a soda fountain. In this case the fountain 95 includes a dispensing valve tap 83 operated by a. valve control leverlil. The hollow head is provided with a window containing suitable advertising display matter I05, similar in scope to the display matter 33 and 18 of the hollow heads 31 and i6. Acontact pin 89 i connected in a signal circuit which includes the filament of the lamp bulb Hi5 housed in the hollow head 86.
A suitable control switch Si is attached to the arm of the fountain 95 by means of an adjustable pipe clamp 92 and its associated clamping screw t3. Low voltage supply lead 94 is connected to a suitable source of low voltage supply such as the low voltage secondary winding 56 of the transformer (Fig. 1)..
The low voltage supply lead 94 is in electrical continuity with the contact point of the control switch 91. The assembly of the control switch ill is generally similar to the assembly of the .control switch 5flp(Fig..3) ,rso that whenever the valve control lever 81 is in an upright position, a signal circuit is completed through the filament of the lamp bulb I06 housed by the hollow head 88, through contact pin 89, contact point to and low voltage supply lead 94, to a suitable source of low voltage (such as the low voltage secondary winding 56 of Fig. 1), thus lighting the lamp bulb N16 to display the advertising material I05 through the window I04. When the handle 86 is opera-ted, valve control lever 81 moves in such a direction as to separate contact pin 89 and contact point 9!], thus interrupting the signalling circuit through the lamp bulb I06 and extinguishing the lamp and the display I05. Control lever 81 also opens the tap 88 to dispense the beverage into the drinking glass 95. When the valve control lever 87 resumes its normal (upright) position contact pin 89 re-engages contact point 88 to re-establish the signalling circuit, thus relighting the lamp lot to again display the advertising matter m5 through the window I04.
While the miniature lamps 49, 65, and lit have been described as of the screw base type, it should be understood that any other form of lamp may be used by modifying the adapters 23, and EH to accommodate the desired type of lamp.
While there has been disclosed in this specification certain forms in which the invention may be embodied, it is to be understood that the said forms are shown for the purpose of illustration only, and that the invention is not to be limited to the forms disclosed, but may be modified and embodied in various other forms without departing from the spirit of the invention.
