COMBINED WALL SWITCH AND ELECTRIC CLOCK Filed June 26, 1944 INVENTOR. 62 0/90 NDEESO/V.

Patented Jan. 8, 1946 COMBINED WALL SWITCH AND ELECTRIC CLOCK Church Anderson, Arcadia, Calif.

Application June 26, 1944, Serial No. 542,098

1 Claim.

My invention relates to a combined wall switch and electric clock and has for its principal object, to provide a wall switch cover plate with a shelflike support for a small electric clock and said cover plate providing a housing for electric conductors which connect service line contacts within the wall switch with the contacts of said clock, thus enabling a clock to be conveniently connected to any wall switch and without the requirement of extension cords, plugs, sockets and the like.

A further object of my invention is to provide a wall switch and clock arrangement of the character referred to, which is simple in structure, capable of being readily installed on all standard embedded wall switch boxes, and which presents a neat and finished appearance.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:

Fig. 1 is a perspective view of the combined wall switch cover plate and electric clock.

Fig. 2 is a vertical section taken on-the line 22 of Fig. 1.

Fig. 3 is an elevational view looking against the rear side of the cover plate.

Fig. 4 is a cross section taken on the line 4-4 of Fig. 3.

Fig. 5 is a cross section taken on the line 5-5 of Fig. 3.

Fig. 6 is a diagrammatic view of the electrical connection between the current supply line and the contacts of the clock.

Referring by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, Hi designates a conventional wall switch box having the usual contacts I l for the supply line conductors [2, with a switch (not shown) in said line and which switch is operated by a short pivoted arm such as l3, or by push buttons.

In accordance with my invention, the conventional switch box cover plate M of metal or plastics, provided in its rear face with a shallow recess [5 and projecting from the upper end of said plate is a shelf l6 adapted to receive and support a. small conventional electric clock ll. Plate I4 is provided with an aperture 18 for lever I3 and with apertures IQ, for screws 20 which detachably secure said plate to the switch box 19.

Positioned within recess I 5 is a plate 2| of suitable insulation, for instance, hard rubber, fibre or plastics and embedded therein are electrical conductors 22, the lower end portions of which project beyond one edge of plate 2| so as to engage line contacts I l.

The upper portions of conductors 22 projects upwardly from plate 2|, through openings 23 formed in the upper portion of cover plate I4 and thus the upper ends of said conductors engage the clock contacts 24. Plate 2! which carries the conductors 22 is held in proper position with recess it by the screws 26 which pass through apertures 25 in said plate.

The electric clock IT may be secured to shelf it in any suitable manner, for instance, by means of a screw or screws such as 26 which pass through the shelf into the lower part of the clock housing.

When plate 14 is secured to the switch box by means of the screws 26, electric current will pass from line wires l2, to and through conductors 22 and from the latter to the clock motor contacts 24.

Shelf ltformed integral with the cover plate, provides a convenient support for the clock and the conductors within the recess in the rear face of the plate provide the necessary electrical connections for the clock, thus eliminating all exposed fittings such as extension cords, plugs and the like.

Thus it will be seen that I have provided a combined wall switch and electric clock which is simple in structure, inexpensive of manufacture and very effective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form and construction of the various parts of my improved cover plate and electric clock may be made and substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claim.

I claim as my invention:

An electric clock mounting comprising a plate, a shelf projecting outwardly from the upper end of said plate, there being apertures through that portion of said shelf above said plate, there being a recess formed in the rear side of said plate, which recess communicates with the apertures in said shelf, a plate of insulating material secured to said plate within the recess therein, a pair of electric conductors embedded in said plate of insulation, the upper ends of which conductors project through the apertures in said shelf, the lower ends of which conductors project laterally from the side of said plate of insulation and there being an aperture formed in the central portion of said plate.
