Abstract

Abstract An indicating instrument mounted in a cylindrical casing which has attached to its front edge, and surrounding the window thereof, a ringlike bezel provided with apertured mounting flanges. The front window, bezel and casing constitute a rigid unitary assemblage. Surrounding and slidable on the casing is a thick-walled sleeve having a cylindrical bore and a polygonal exterior. The sleeve is adapted to be clamped securely to the rear of a panel in back of an instrument opening therein, and to extend rearwardly therefrom. Screws which are operable from the front of the instrument, releasably secure the flanged bezel to the sleeve, thereby to mount the instrument on the panel. When the front screws are removed, the bezel is free of the sleeve which surrounds the instrument casing, thereby enabling the instrument to be withdrawn forwardly of the panel for servicing. The sleeve has threaded holes to accommodate the screws, whereby the removal and replacement of the instrument can be done quickly and easily, completely from the front of the panel.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 152 words
An instrument mounting comprising, in combination: a. an instrument casing including a tubular body portion, b. a bezel attached to the front of the casing and projecting past the sidewalls thereof, c. a sleeve surrounding the casing and removable past the casing rear, d. fastening means operable from the front of the bezel, releasably securing the bezel and sleeve to each other in end-to-end relation. e. a clamp device extending around the sleeve and adapted to be attached to the rear of a panel provided with an opening through which the instrument casing can extend and pass, said clamp device having operable means enabling it to rigidly grip the sleeve so as to secure the latter to the panel at the rear and around the opening thereof, f. loosening of said fastening means so as to release the bezel from the sleeve enabling the casing to be withdrawN forwardly of the sleeve.
Claim 2
Dependent Claim 152 words
An instrument mounting comprising, in combination: a. an instrument casing including a tubular body portion, b. a bezel attached to the front of the casing and projecting past the sidewalls thereof, c. a sleeve surrounding the casing and removable past the casing rear, d. fastening means operable from the front of the bezel, releasably securing the bezel and sleeve to each other in end-to-end relation. e. a clamp device extending around the sleeve and adapted to be attached to the rear of a panel provided with an opening through which the instrument casing can extend and pass, said clamp device having operable means enabling it to rigidly grip the sleeve so as to secure the latter to the panel at the rear and around the opening thereof, f. loosening of said fastening means so as to release the bezel from the sleeve enabling the casing to be withdrawN forwardly of the sleeve.
Claim 3
Dependent Claim 49 words
An instrument mounting as in claim l, and further including: a. an instrument panel having an opening for the casing, b. said sleeve fitting into the panel opening, c. the back surface of said bezel abutting the front edge of the sleeve and facing the front of the panel.
Claim 4
Dependent Claim 40 words
An instrument mounting as in claim l, wherein: a. the sleeve has a length exceeding one-half the depth of the instrument casing, thereby to support the casing in aligned position when it is only partially withdrawn forwardly of the sleeve.
Claim 5
Dependent Claim 39 words
An instrument mounting as in claim l, wherein: a. the sleeve comprises a casing having a cylindrical bore and a polygonal exterior, b. said bezel having a polygonal outer periphery similar in shape to the exterior of the sleeve.
Claim 6
Dependent Claim 26 words
An instrument mounting as in claim 4, wherein: a. the fastening means comprises screws passing through the bezel and threaded into the end of the sleeve.
