Abstract
Abstract A device for indicating the angular position of a rotatable member of a type adapted for mounting on a panel. A bracket for mounting the device on the panel includes a first axially extending tang adapted for insertion into a slot formed in a first portion of the indicating device. The slot includes two spring fingers extending radially inward. The spring fingers engage the tang to prevent the indicating device from rotating relative to the panel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
In a device for indicating the angular position of a rotatable shaft of a type adapted for mounting on a panel having a first hole provided therethrough for passage of said shaft, said indicating device including a portion having means defining a slot formed therein, the improvement comprising: a bracket for mounting the indicating device on said panel, said bracket including a first member having side walls and adapted for insertion into said slot of said indicating device, said slot defining means including resilient means having inner surfaces extending parallel to and radially outward from the longitudinal axis of said slot, said first member being inserted into said slot to force said resilient means radially outward to generate a return spring force acting between the inner surfaces of said resilient means and the side walls of said first member to prevent relative movement between said bracket and said indicating device; and means to prevent any relative movement between said bracket and said panel, to thereby prevent any relative movement between said indicating device and said panel.
Claim 2
Dependent Claim
176 words
In a device for indicating the angular position of a rotatable shaft of a type adapted for mounting on a panel having a first hole provided therethrough for passage of said shaft, said indicating device including a portion having means defining a slot formed therein, the improvement comprising: a bracket for mounting the indicating device on said panel, said bracket including a first member having side walls and adapted for insertion into said slot of said indicating device, said slot defining means including resilient means having inner surfaces extending parallel to and radially outward from the longitudinal axis of said slot, said first member being inserted into said slot to force said resilient means radially outward to generate a return spring force acting between the inner surfaces of said resilient means and the side walls of said first member to prevent relative movement between said bracket and said indicating device; and means to prevent any relative movement between said bracket and said panel, to thereby prevent any relative movement between said indicating device and said panel.
Claim 3
Independent Claim
162 words
A device for indicating the angular position of a shaft of a variable resistor mounted on a panel, said shaft extending through a first hole provided in said panel, said panel including a second hole, said device comprising: a first member including means defining a slot provided in a wall facing said panel, said slot defining means including resilient means; and a mounting bracket disposed between said wall of said first member of said device and said panel, said bracket including a first opening for said shaft of said variable resistor, and an axially extending tang portion, said tang being insertable into said slot whereby the outer walls thereof contact the inner walls of said resilient means to spring said resilient means radially outward to provide a force to prevent relative movement between said bracket and said device; and means to prevent relative movement between said bracket and said panel to thereby prevent relative movement between said indicating device and said panel.
Claim 4
Independent Claim
162 words
A device for indicating the angular position of a shaft of a variable resistor mounted on a panel, said shaft extending through a first hole provided in said panel, said panel including a second hole, said device comprising: a first member including means defining a slot provided in a wall facing said panel, said slot defining means including resilient means; and a mounting bracket disposed between said wall of said first member of said device and said panel, said bracket including a first opening for said shaft of said variable resistor, and an axially extending tang portion, said tang being insertable into said slot whereby the outer walls thereof contact the inner walls of said resilient means to spring said resilient means radially outward to provide a force to prevent relative movement between said bracket and said device; and means to prevent relative movement between said bracket and said panel to thereby prevent relative movement between said indicating device and said panel.
Claim 5
Dependent Claim
43 words
A device in accordance with claim 2 wherein said mounting bracket includes means extending in a direction opposite to that of said tang, said means being inserted into said second hole to permit said device to be properly indexed relative to said panel.
