F. E. PAVELKA SICK ROOM LIGHT Filed April 11, 1935 2 Sheets-Sheet l Invento'r 7 E. Pavelka I F. E. PAVELKA S ICK ROOM LIGHT Filed April 11, 1935 2 Sheets-Sheet 2 ransf mer I nvento'r 7 E. Pavel/m Attorney Patented Dec. 10, 1935 UNETED STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in the general art of illumination and more particularly to a light especially adapted for sick room use.

The principal object of the present invention is to provide in conjunction with the usual standard room lighting fixture a dim and shaded light which would not only light up the switch, but would also afiord a dim light for the room.

During the course of the following specification other important objects and advantages of the invention will become apparent to the reader.

In the drawings:

Figure 1 represents a front elevational view of the switch plate and switch with the auxiliary light mount.

Figure 2 represents a vertical sectional view taken substantially on line 22 of Figure 1.

Figure 3 represents a diagrammatic view disclosing the electrical circuit when the auxiliary light is of low voltage and suitable candle power.

Figure 4 represents a diagrammatic view showing the circuit employed when the auxiliary light is of substantially the same voltage as the house light but small wattage.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 2 that numeral 5 represents the wall of a sick room and numeral 5 represents the switch boxlike plate which is provided with a slot 7 in its front through which the snap button 8 projects. At the top of this switch box-like plate 6 a hood 9 is provided and this hood has an inclined wall MB for supporting the lamp socket H which receives a small bulb 92. In the upper portion of the switch box like piate 6 a shelf 53 is provided to support the small snap switch M for the bulb E2, the switch i l and lamp l2 being connected by wires 55 in series with the step down transformer It, the opposite sides l'ii3 of its input being connected into the light switch circuit l9 branched from one of the main wires A, which circuit l9 and I90, contains the usual bright room light bulb 25]. Obviously, the lights l2-2il are independently controllable through the switches M-8, it being apparent that the bulb I2 can be energized by closing the switch M without affecting the lamp 20.

Figure 4 represents the bulb H as Hot and has a bulb of substantially the same voltage power but small wattage as the standard room light 20. Aside from being of the same wattage, the transformer I6 is eliminated and the wires I5 are mere- 5 1y connected into one of the circuit wires of the lamp 20.

It can be seen that a fire alarm is included in the system and is clearly shown in the diagrammatic views of Figures 3 and 4. This alarm con- 10 sists of the connection 2i across the secondary of the step down transformer, and in this connection! are the electrodes 22 which protrude into the goose-neck portion 23 at the upper end of the thermometer 2G, and also in this connection 2| is the buzzer 25. The thermometer 24 has the mercury bulb 26 at its lower end and this is finally seated in the depression 27 of the front wall of the plate 6, while the upper goose-neck portion 23 eX- tends through an opening 28 in the upper portion of the plate 6.

In the event a stepdown transformer it is not employed as hereinbefore mentioned, the connection 2i is made in the manner shown in Figure 4.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed is:

An illuminated switch for a room lighting circuit comprising an elongated supporting panel, a switch for the room lighting circuit behind said panel with an operating lever exposed through said panel, a depending hood secured to the upper portion of said panel, a socket secured beneath said hood in a position to illuminate said lever, an electric light bulb in said socket, a switch receiving compartment in said hood, a switch in said compartment for controlling the energization of said bulb and a transformer receiving compartment in the lower portion of said panel for reducing the line voltage for the bulb circuit.
