Abstract
A simple electrical timer switch control for consumer users is described. It provides automatic time control of outdoor appliances such as lawn sprinklers. A simple, novel, and unique hermetically sealed outdoor casing provides protection from electrical shock hazzard while maintaining the portable characteristics of the control. Means are provided for selecting any one, or more, time interval(s) in any given 24 hour time period; and, for automatically overriding the selected time interval(s) within any 24 hour period, or combination of 24 hour periods, within any given 14 day period.

An electrical timer switch control means comprising:
- timer means, a time switch, timer operating means, timer switch operating means, and time switch circuit means;
- an electrical load in a casing;
- said casing having a main quadric or frustoconical member the tapered peripheral extremity of which circumferentially abuts the peripheral extremity of a flat bottom cover thereby enclosing the bottom of said main frustoconical member, and the opposite peripheral extremity of said quadric or frustoconical member circumferentially abuts one peripheral extremity of a section of right circular cylinder and is contiguously attached thereto, a panel affixed to and closing said right circular cylindrical section at the opposite end thereof, said panel having a flat portion spanning said cylindrical member with a flange around the periphery of said panel flat portion, peripheral extremity of said panel flange in contiguous circumferential abutment with the peripheral extremity of said right circular cylinder;
- a continuous annular gasket inserted contiguously between said panel flange peripheral extremity and said main casing member peripheral extremity, said panel flange peripheral extremity is sandwiched circumferentially into the upper annular face of said gasket, and the opposite annular face of said gasket is telescoped over said main casing member peripheral extremity thereby providing a hermetical seal between the exterior surface of said panel and the interior of said main quadric casing member;
- a top cover comprising a quadric or frustroconical portion and a cylindrical portion the peripheral extremity of which is telescoped over the exterior surface of said panel peripheral flange and abuts circumferentially said upper annular face of said annular gasket thereby providing a hermetical seal between the exterior surface of said top cover and the exterior surface of said panel;
- said timer means and said timer operating means disposed on the exterior surface of said panel, being non-electrical;
- said timer means, said time switch, and said timer operating means disposed on the interior surface of said panel, being electrical;
- said timer operating means disposed on the interior surface of said panel motivating said timer means disposed on the exterior surface of said panel, by means of a single rotating drive shaft that protrudes through a hermetically sealed bushing extending from said panel interior surface to said panel exterior surface;
- said timer switch operating means disposed on said panel exterior surface actuating said timer switch operating means and said time switch, disposed on said panel interior surface by means of a single angularly oscillating drive shaft means protruding through a hermetically sealed bushing extending from said panel interior surface to said panel exterior surface;
- means accessible from the exterior of said casing for connecting an external power source to said timer operating means and for connecting said external power source in series with said electrical load and said time switch;
- and said timer operating means motivating said timer switch operating means causing said time switch to open and close in an automatically repetative cycle thereby energizing and de-energizing said load by means of said timer means.

An electrical timer switch control means comprising:
- timer means, timer operating means, time switch, timer switch operating means, time switch circuit means, and an electrical load in a casing;
- said casing having a main casing member of right circular cylinderical configuration, a bottom cover fitted into and fixed to said main casing member at one end thereof, a panel affixed to and closing said casing member at the opposite end thereof, said bottom cover having a flat portion spanning said main casing member with the periphery of said bottom cover flat portion abutting the periphery of said main casing member, and said panel having a flat portion spanning said main casing member, with peripheral extremity of said panel in contiguous circumferential abutment with the peripheral extremity of said main casing member;
- a continuous annular gasket inserted contiguously between said panel peripheral extremity and said main casing member peripheral extremity, said panel peripheral extremity is fitted circumferentially to an annular face of said gasket, and a second annular face of said gasket is fitted to said main casing member peripheral extremity thereby providing a heremetical seal between the exterior surface of said panel and the interior of said main casing member;
- a top cover comprising a quadric portion and a cylindrical portion the peripheral extremity of which abuts circumferentially an upper annular face of said annular gasket thereby providing a heremetical seal between the exterior surface of said top cover and the exterior surface of said panel;
- said timer means and said timer switch operating means disposed on the exterior surface of said panel being non-electrical;
- said timer means, said time switch, and said timer operating means disposed on the interior surface of said panel, being electrical;
- said timer operating means, disposed on the interior surface of said panel motivating said timer means disposed on the exterior surface of said panel, by means of a single rotating drive shaft that protrudes through a hermetically sealed bushing extending from said panel interior surface to said panel exterior surface;
- said timer switch operating means disposed on said panel exterior surface actuating said timer switch operating means and said time switch, disposed on said panel interior surface, by means of a single angularly oscillating drive shaft means protruding through a hermetically sealed bushing extending from said panel interior surface to said panel exterior surface;
- said electrical load housed in said casing interior and energized by a power source located exterior of said casing;
- conductor means extending from the exterior to the interior of said casing for connecting said power source to said timer operating means;
- said time switch circuit means in said casing interior for connecting said time switch and said load in series with said power source;
- said timer means motivating said timer operating means causing said time switch to open and close in an automatically repetative cycle thereby energizing and de-energizing said load by means of said timer means;
- and means for coupling the output of said load from the interior to the exterior of said casing without requiring access to the interior of said casing.
