PATENT OFFICE CLAUDE I. CRONBURG, OF CLEVELAND HEIGHTS, OHIO, ASSIGNORS TO FRANK R. UIBLE, OF CLEVELAND, OHIO ADVERTISING DEVICE Application filed May 14, 1931. Serial mfsazsoo.

This invention relates to advertising display devices and particularly to a magnetically operated device for use in connection with window displays and the like.

The principal object of this invention is a device of the character described which may be operated from the outside of the display window by any passerby for the purpose of selectively operating one or more devices within the display window.

Another object of our invention is to provide an operating device of this character part of which may be placed on the inside of the show Window and part on the outside,

1 these parts cooperating magnetically through the medium of the glass, and withoutany mechanical connection between the parts, as a result of which the necessity of drilling or otherwise cutting the glass or of making electrical or other connections from the outside into the display window or show case is eliminated.

Another advantage of our invention resides in the fact that the operator is not endangered 1) handling any electric currents which wou d be especially dangerous were the operator standing on the pavement or ground.

A similar advantage is that the operator can operate the device and the machines on display only in a predetermined manner, and cannot in any way cause damage to the machine by improper operation of or by damaging the outside operating element.

A more specific object and advantage of our invention is an operating switch for this purpose which may be manufactured economically and in a large variety of forms, and .which may be readily and easily placed in operating position. and does not require any change in the display window itself.

An other object of our invention is a device arranged to intrigue the passerby by causing actuations of the machines inside of a display window through the medium of the glass front and with no visible connection between the part operated by the passerby and the machines within the display Window and to direct his attention to each particular machine in turn, by permitting operation of each machine selectively by the passerby himself.

Other objects and advantages will be come apparent from the following specification in which reference is made to the drawings by reference numerals.

In the drawings Fig. 1 is a somewhat diagrammatic illustration of a display window with the device in position therein for operating the various machines being advertised.

,Fig. 2 is a sectional view of the display window illustrated in Fig. 1 and is taken on a plane indicated by the line 22.

Fig. 3 is a front elevation of a form of magnetic switch embodying the principles of our invention.

Fig. 4 is a cross sectional view of the switch illustrated in Fig. 3 with the operating dial therefor in operating position.

Fig. 5 is an enlarged partial sectional view taken on a plane indicated by the line 5-5 of Fig. 3.

Fig. 6 is a diagrammatic illustration of one form of circuit used in combination with the switch for operating a large number of machines.

Referring particularly to Figs. 1 and 2 there is illustrated a display window in which are a number of machines designated 2, 3, 4, 5 and 6, which it is desired to operate from the outside of the window. The display win dow is provided with the usual plate glass front 7 for protecting and guarding the machines. The switch element of our device to which the machine to be operated may be magnetically or electrically connected is indicated at 10 and is arranged on the inside of the display window and preferably positioned against the inner face of the glass 7, as better illustrated in Fig. 4. r

A manually operated dial or other movable element 12 is positioned on the outside of the glass preferablv in alignment with the switch 10 for operating the switch so that the passerby may selectively operate any one of the devices in the window from the outside. In this manner his attention may be more efi'ectively arrested and directed to each of the machines in turn. The elements through the medium of the glass 7 and are grammatically'illustratedin Fig. 6. 'The connected in no other manner.

As a result of this arrangement the attention or" the operator is retained, inasmuch as he can see no connection between the elements he operates and the machinesv operated thereby. 7 As mentioned it is often desirable to operate selectively one or more of the machines on display and ha e hei na or o our invention. by way of illustration which is arranged for this purpose. Furthermore, to

more definitely focus the attentionlof the:

operator on the particular machine being operated, we have provided lights 18 connected one in parallel with each machine and positioned to illuminate theparticular machine while it is being operated. By turning the dial 12 to predetermined positions each of thjemachinesin turn may be rendered operative andat the same time illuminated, usually by closing electrical circuits connected withthe respective machines. By turning the dial 12 to'difierent positions relative tothe switch 10the circuits to each machine are in turnfopened and closed. Since it is desirable that the dial 12 return to a normal position'o f rest and disconnect the machines when the pats serby has'released the 'dial, we may arrange the switch 10 sothat when the dial returns to its normal position of rest the switch willconnectthe usual window flood lights with a source of power and accordingly will disconnect these lights when any particular machine is being operated.

The dial 12 maybe mounted on any suitable pivot connection in a body 15 which is glued onto the glass of the window. The weight 9 is provided on the dial to overb alance the same and cause 'it to return to a 4 predetermined normal poslt on of rest when itisreleased bythe operator. The particular number and arrangement of the machines, light-sand circuits islargely optional, the above being given'by'way of illustration of i. an efiiective'display and to better illustrate the feature of our invention;

'To accomplish these results we prefer to use a switch 110 "such as illustrated in Figs. 3 and 4 and-an electric hookup such as diaswitch iomay be mounted on any'suitable standardl through which the'electric conductors may pass fromthe switch 10 to the respective circuits. In the form illustrated,

the'switch "10 comprises a. circular body 16 on which are mounted a plurality of magnets, for example, three magnets 17, 18 and 19, may be used. These magnets are preferably positioned about 120 apart and equally spaceditrom the center of the circular body. All; the magnetsmay be identical in form and siihilarly mount edso that. the description'of themagnet 1 9 onlymajy be given.

l eierr nst he magn te y e a bar magnet pivotally mounted in a yoke 20 which is secured to the circular body 16, the magnet being held between the yoke arms by a pivot 21 so as to swing freely about its pivot. 1-1 spring 22 which is shown as a leaf spring is secured intermediate its ends to the magnet 19 or the yoke 20, the free ends of the spring engaging the other of the two members so as to yieldably hold the magnet in a predetermined neutral position. Carried byor operably connected to the magnet 10 is a contactor 23. Arranged at each side of this contactor in the path of movement described thereby as the magnet swings about its pivot are complementary contactors 2a and 25, each ofwhich is connected in a circuit later to be described. These contactors are preferably disposed one at each side of thecontactor 23.

In this illustrative form of our invention the magnets 17, 18 and 19 are positioned with the south poles pointing inwardly toward the center of the body 16 and extend radially with the north poles pointing outwardly from the center. The dial 12 carries a magnet 26 which may be a bar or horseshoe magnet. This magnetis secured to the dial so as to turn there with. If a single magnet is used it should extend diametrically throughthe center of the dial with the magnet ends positioned so as to describecircles through the south pole,

for example, of the ma nets 17 18 and 19a:

ried on the magnet 19 is brought into contact with the contactor 25. Similarly'as the south 7 pole of thelmagnet 28 is disposed in front of the south pole of the magnet 19, it repels this pole of the magnet 19, causing the magnet to swing in the opposite direction about its pivot, thus bringing the contactor .3 into contact with the contactor 2%, for purposes later to be described. r

lVe prefer that the elements 17 18 and 19 be permanent magnets instead of ordinary iron bars, so that two simple contacts may be obtained for each element. However, instead of magnetizing the members, 17, 18 and 19, these may be of ordinary iron and have only single contact each, andthus be attracted by the magnet to effect this contact. A double contact is also possible when these elements are of iron and may be obtained by arranging the magnetic means 26 so that the elements 17 18 and 19 are each attracted on one side of the pivot point to the magnet 26 to effect one contact and are attracted on the opposite sides of the pivot points to swing the elements inthe opposite direction for effecting another contact, Again, if the elements 17, 18 and 19 are permanent magnets, iron elements instead ments it will efi'ect movement thereof. As

stated however, we prefer that both the element 26 and the elements 17 18 and 19 be permanent magnets so that a heavier flux is obtainable and operation better insured.

Referring again to the preferred form of our invention, when the dial 12 is rotated each of the magnets 17 18 and 19 will be moved to one or the other of its contact positions, thus closing the circuits and operating a device in the window. In the case of the heavier machines, for instance, washing machines, electric fans and the like, a power circuit of 110 Volts is usually required. In machines operating on such a circuit it is usually damaging to the machines to start and stop them Y too quickly, and furthermore causes a consid erable are on the contactors which tends to burn or otherwise deleteriously affect the contacts and adjacent working parts of the switch. To eliminate these disadvantages and I to prevent starting and stopping the machines as the dial is being moved from one position to another, we find it expedient to use a circuit such as will now be described,

. and to provide in the circuit a retarded relay so that not only must each of the magnets 17 18 and 19 be operated to cause a contact but also retained in such position for a short interval before the power circuit will become operative and start themachine. Since the circuits for each of the magnets may be the net 26 in front of the south pole of the magnet 19, the like poles will repel each other and consequently the magnet will be swung about its pivot point to the position shown a in Fig. 6, bringing the contactor 23 carried by the magnet into contact with the contactor 24. The magnet 19 may be connected to one side of a low voltage source of electric current and the contactor 24 connected to the other side, so that upon contact of these elements the circuit is completed. Such a circuit could directly operate a device utilizing low voltage power supply, but inasmuch as a heavy current would be detrimental to the parts as described, we prefer to use a higher voltage power circuit and to operate it from the low voltage circuit. The circuit 24. A lead 38 is connected tothe line between the battery and relay 36 and passes to the coil of theoperating relay 37 and then tween the contactor 23 and the contactor 24, a closed circuit is formed from the battery through the retarded relay 30 and the oper- Y I ating relay 36. The movable cont-actor 40 of the operating relay 36 immediately closes the power line 41 connecting the machine tobe operated with one side of the retarded relay 30, for example, with the movable contact 43. Slightly later the contact43 moves to connect the line 41 to one side of a source" contactors 23 and 24 in contacting'relation for a short interval before closing of the power circuit results.

Thus, as described, the passerby must retain the dial 12 for a short interval at one of the operating positions before operation is obtained, and revolving of the dial 12 will not rapidly start and stop each machine in turn.

A similar hookup may be used for therelay 37 so that upon contact of the contactor 23 with the contactor 25 another machine may be operated. A separate operating relay is provided for each contact, the retarded relay being common to all.

The circuits we have shown are illustrative of a number of possible circuits which may be used, depending upon the particular device to be operated, voltage required, etc.

From the foregoing description it is apparent that not only is the passerby protected from electric currents, but likewise it would be impossible for him to improperly operate the machine on display. Furthermore, since there is no visible connection be tween the dial and the switch and since each of the machines may be operated selectively by him, consequent upon his operating the dial, his attention will be retained and focused directly on each machine in turn.

While we have described our invention particularly adapted to use in connection with a display window or show case having a glass or transparent front, obviously it is not necessary that it be limited to this use, as quite a desirable advertising attraction is afforded by placing the operating elements in spaced relation with no visible connection therebetween. It is pointed out, however, that if a solid and imperforate wall such as the glass 7 used between the switch and the dial, that no ferrous substance should be included in the imperforate wall in a position such as to affect the magnets. Again it may be pointed out that while we prefer to use such a switch to form various electric contothe contactor 25. \Vhen the magnet 19 isactuated as described, to cause contact be-:
