ATTORNE Patented Nov. 1, 1938 ILLUMINATING ATTACHMENT FOR swiTon- DEVIC Morris L. Blgman, Brooklyn, N. Y.

Application April 25, 1936, Serial No. 76,342

7 Claims.

This invention relates to switch devices of various kinds and classes, and particularly to the provision of an attachment adapted to be coupled with a switch device to indicate the location of the device as well as to indicate the off or open circuit position thereof; and the object of the invention is to provide an attachment of the class and for the purpose specified in the form of an electrically actuated member, such for example,

as a neon light or glow lamp, with means for mounting or supporting the lamp in such position asto render the same visible externally of the switch device or the mounting or finish plate of such a device so as to indicate the location of the device in a dark room or compartment; a further object being to provide an attachment of the class described which may be coupled and uncoupled with a switch device without modifying the structure of the device or interfering with the operation thereof; and with these and other objects in view, the invention consists in an attachment of the class and for the purpose specified, which is simple in construction, eflicient in use, and Which is constructed as hereinafter described and claimed.

ing forms a part, in which the separate parts of my improvement are designated by suitable refer- 3o ence characters in each of the views, and in which:

Fig. 1 is a front and sectional view of one form of attachment which I may employ, illustrating its mounting in connection with one type of 3:, switch device.

Fig. 2 is a longitudinal section through the device shown in Fig. 1.

Fig. 3 is a diagrammatic view illustrating the arrangement of the illuminating device in the 40 electric circuit controlled by a switch device.

Fig. 4 is a view similar to Fig. 1, showing only a part of the construction and showing a modification.

Fig. 5 is a face view of a switch device showing 45 another form of attachment.

Fig. 6 is a side and sectional view of the construction shown in Fig. 5.

Fig. '7 shows a modified form of switch plate which I may employ; and,

50 Fig. 8 is a plan view of a'switch device controlling an electric circuit or appliance, with one of my improved attachments mounted in connection therewith.

I In ca. ying my invention into effect, I propose 5 to provide an attachment which is so constructed as to provide a quick and simplified coupling or mounting of the attachment in connection with various kinds and classes of switch elements so as to provide means for locating the position of a switch element, especially in a dark roompr com- 5 partment, as well as to indicate the off or open circuit position of the switch.

In Figs. 1 and 2 of the drawing, I have shown one form of construction, and in these figures, It) represents an outlet box or casing of conventional 10 form in which is mounted a body of insulating material ll forming the switch body proper, and on which is supported the conventional screw terminals l2 and I3 with which the circuit wires l4 and I5 are coupled. At It, I have shown the 15 movable switch element which opens and closes the circuit through the wires l4 and IS in the usual manner, and as the structure of the element l5 and its associated parts forms no direct part of this invention, and as these elements are well known, no specific disclosure or description is herein made. However, in Fig.3 of the drawing, the element I6 is shown in a diagrammatic illustration in its relationship to the wires I 4 and I5 to complete the circuit therethrough and through 25 the wire Ma, in which wires a suitable electric light or other appliance I! may be arranged.

In switch devices of the kind illustrated in Figs.

1 and 2 of the drawing, an outer wall finishing plate I8 is usually employed through which the 30 switch element l6 projects. The plate 18 is held in place by screws H! which couple with extending arms 20 on the body II in the conventional manner.

At 2 I, I have shown an illuminating attachment which is in the form of a hollow casing in which a neon light or glow lamp 22 is adapted to be supported and to be exposed externally through apertures or openings 23 formed in the casing 2|. The casing includes at one end portion hookshaped arms 24 which are adapted to extend around one beveled edge portion Illa of the plate I8 in the manner indicated in Fig. 2 of the drawing to support the housing 2| upon the plate I8 in any desired position of adjustment. While the casing is shown supported above the element I6 in Fig. 1 of the drawing, the same may be supported below said element or at either side thereof, and especially in locating the lamp 22 in close proximity to the terminals l2 and 13 of the switch body I I. Extending from the lamp 22 are circuit wires 25 and 26 which couple with resistance plates or elements 21 and 28. These elements are coupled with the binding posts I! and I3 as clearly illustrated in Figs. 1 and 2 of the II drawing, and 'also diagrammatically illustrated in Fig. 3. The wires and 26 will be insulated from the point extending from the lamp 22 to the respective resistance plates 21 and 28. These wires will extend through a housing portion Zia on the casing 2| and intermediate the hookshaped members 24.

With this construction, when the switch element I6 is moved into the on or closed circuit position to complete the supply of electric energy to the member I1, the circuit to the neon light or glow lamp 22 will be cut off. However, when the switch element is moved into the off or open circuit position, the electric circuit will be completed through said neon lamp, and the same will be illuminated to indicate the position or location of the switch, especially in a dark room or compartment, or in installations such as that disclosed in Fig. 8 of the drawing, the neon lamp will be utilized to indicate in a switch of the type herein shown, the off or open circuit position of the switch. In this Fig. 8, I have shown at 29 a switch device of more or less conventional form, and such as is employed in an extension cord controlling various kinds and classes of electrical appliances, electric irons, toasters and the like, the switch device consisting of separate parts secured together by screws 30. At 3|, I have shown the manually actuated switch element for opening and closing the circuit in the customary manner. At 32, I have shown one of my attachments in the form of a casing supported between the separate parts of the device 29, the casing being aperturedas indicated at 33 to expose a neon bulb 34 therethrough, which bulb is placed in circuit with the terminals of the switch 29 in a manner similar or equivalent to the attachment shown in Figs. 1 and 2 of the drawing, and diagrammatically illustrated in-Fig. 3.

In Fig. 4 of the drawing, I have shown a slight modification of the construction shown in Figs. 1 and 2, in which an elongated casing 35 is disposed horizontally across the top of the plate l8 and is supported in connection with one of the screws l9 employed for retaining the plate I8 in position. With this construction, the casing 35 includes a hollow extension 36 through which the wires from the neon bulb 31 pass. This extension 36 may or may not include the hook-shaped members similar to the members 24. The casin 35 will have elongated apertures 38 for exposing the neon bulb therethrough.

In Fig. '7 of the drawing, I have shown another method of carrying my invention into effect, which consists in substituting for the plate I8, a plate 39 of similar general form but modified in its construction by stamping from the front wall or surface thereof an outwardly projecting hollow casing portion 40 preferably adjacent the switch element Ma, and in providing apertures 4| in the hollow portion 40 so as to expose a neon glow lamp supported within the casing portion 40 through said apertures. In other words, instead of providing an independent casing part, the finishing plate may constitute the attachment to provide means for supporting and arranging the neon lamp n position to be seen, to indicate the location of the switch in a room or compartment. In this connection, it will also be understood that it is not absolutely essential that the neon light be arranged beyond or outwardly of the surface of the switch plate, but this arrangement is preferred, in that it enlarges the angle of visibility, and thereby simplifies the problem of locating the position of a wall switch of this type.

In Figs. 5 and 6 of the drawing, I have shown another form of attachment which differs primarily from the structure shown in the other figures by the inclusion of a movable element on the attachment. In these figures, I have shown at 42 a casing including hook members 43 for engaging the plate I8 of the switch. At one end of the casing 42 is an upstanding wall 44 in connection with which a supplemental casing 45 is slidably mounted by virtue of a pin 46 operating in an elongated slot 44a in the wall 44 so as to permit free swinging movement of the casing 45 with respect to the casing 42. The casing 45 has a portion 41 which is adapted to be slipped onto and'frictionally engage the switch element Hib and to be movable therewith. The casing 45 also includes a cylindrical portion 48 in which a neon lamp or bulb is supported and exposed through apertures 49 formed in said cylinder, the wires from the neon bulb 50 extending through the casing 42 and being coupled with the terminals of the switch as in the construction shown in Figs. 1 and 2 of the drawing.

While I have shown a few forms of attachments, and have indicated different arrangements thereof in connection with switch devices, my invention is not limited in these respects, and the same may be applied to various kinds and classes of switch devices, and the structure of the attachment will be modified to suit the different forms and construction of switch devices employed.
