Abstract
An indicator post has a head assembly for use with an underground post indicator valve or a wall mounted post indicator valve. The head assembly includes an upper body having a removable cap rotatably supporting an operating stem coupled to an operating rod for engaging the valve. A leading bogie assembly is threadably mated to a threaded sleeve of the operating stem and includes open and shut targets slideably supported on the bogie assembly to allow adjustment of the targets for valves that open and shut with different numbers of revolutions.
Claims20
An indicator post for an underground or wall mounted post indicator valve comprising:
- a head assembly having an upper body with a removable cap;
- an operating stem rotatably supported by said cap, said operating stem including a threaded body for receiving a leading bogie assembly including slideably adjustable targets for displaying the status of the valve;
- said leading bogie assembly including a leading bogie having an aperture threadably coupled to said threaded body of said operating stem, said leading bogie including opposed surfaces and a pair of extension plates coupled to said opposed surfaces, said extension plates each including a guide slot, and wherein said targets include a tab extending into said guide slot for guided movement during adjustment of said targets;
- and
- an operating rod having one end coupled to said operating stem and an opposite end coupled to one of an underground valve and a wall mounted valve for the actuation of the valve coupled to said operating rod.

An indicator post for an underground or wall mounted post indicator valve comprising:
- a head assembly having an upper body with a removable cap;
- an operating stem rotatable supported by said cap, said operating stem including a threaded body for receiving a leading bogie assembly including targets for displaying the status of the valve;
- said leading bogie assembly including a leading bogie having an aperture threadably coupled to said threaded body of said operating stem, said leading bogie including a pair of alignment ears for engaging inwardly extending guide rails on said upper body such that rotation of said operating stem moves said leading bogie vertically within said upper body, wherein said leading bogie includes opposed surfaces orthogonal to said alignment ears and said leading bogie assembly further includes a pair of extension plates coupled to said opposed surfaces, said extension plates each including a guide slot, and wherein said targets include a tab extending in said guide slot for guided movement during adjustment said targets;
- and
- an operating rod having one end coupled to said operating stem and an opposite end coupled to one of an underground valve and a wall mounted valve for the actuation of the valve coupled to said operating rod.

An improved leading bogie assembly for an indicator post comprising:
- a leading bogie including a pair of targets for displaying the open and shut condition of an indicator post valve, said leading bogie having a threaded aperture for threadably coupling to a threaded body of an operating stem associated with the indicator post, said leading bogie including opposed surfaces for receiving a pair of vertically extending extension plates;
- said extension plates each including a guide slot, and wherein said targets include a tab extending into an associated guide slot for guided movement during adjustment of said targets;
- and
- a slideable coupling for coupling said targets to said vertically extending extension plates.

An improved leading bogie assembly for an indicator post comprising:
- a leading bogie having a threaded aperture for threadably coupling to a threaded body of an operating stem associated with the indicator post, said leading bogie including opposed surfaces for receiving a pair of vertically extending extension plates;
- said leading bogie further including a pair of alignment ears located in orthogonal relationship to said opposed surfaces for engaging inwardly extending guides on an upper body of the indicator post such that rotation of the operating stem moves said leading bogie vertically within an upper body of an indicator post;
- a pair of targets for displaying the open and shut condition of an indicator post valve;
- and
- a slideable coupling for coupling said targets to said vertically extending extension plates, wherein said extension plates each include a guide slot, and wherein said targets include a tab extending in said guide slot for guided movement during adjustment of said targets.

A universal indicator post for use for controlling are underground or wall mounted post indicator valve, said universal indicator post comprising:
- a head assembly having an upper body with a removable cap;
- said upper body having at least one window for displaying the open or shut status of a post indicator valve;
- a leading bogie assembly including slideably adjustable targets for displaying the open or the shut positions of the post indicator valve, wherein said leading bogie assembly includes opposed surfaces and a pair of extension plates coupled to said opposed surfaces, said extension plates each including a guide slot, and wherein said targets include a tab extending in said guide slot for guided movement during adjustment of said targets;
- an operating stem rotatably supported by said cap, said operating stem including a threaded body for receiving said leading bogie assembly;
- and
- an operating rod having one end coupled to said operating stem and opposite end coupled to one of an underground valve and a wall mounted valve for the actuation of the valve coupled to said operating rod.
