Dial holder for magnetic base

Abstract

An adjustable support holder for a gauge device on a magnetic base to provide adaptable positioning and mounting for measuring instruments. The support holder comprises of a gauge engagement platform rotatable with a support base adapted to be mounted on an electro-magnetic attachment for selectively securing on a magnetically attractive surface. An integrated remote locking assembly will selectively release and lock the rotatable platform and attached measuring gauge allowing for 360-degree rotation and orientation there therewith.

Claims

A multi-positional support holder for measuring gauges in different positions comprises, a magnetic base, an upstanding mounting rod on said base, a gauge engagement holder adjustably positioned on said mounting rod, said gauge holder comprising, a support armature, a gauge receiving body member on said support armature, a gauge attachment mount rotatably retained in said gauge receiving body, a control rod adjustably positioned through said armature for selective engagement with a portion of said gauge mount, and means for adjustably positioning said control rod in said armature.

2. The multi-positional support holder set forth in claim 1 wherein said magnetic base is electromagnetic.

3. The multi-positional support holder set forth in claim 1 wherein said support armature is tubular and threadably secured in an opening in said gauge receiving body in communication with a central bore in said gauge receiving body.

4. The multi-positional support holder set forth in claim 1 wherein said control rod comprises, a free end portion of reduced diameter within said armature and said gauge receiving body.

5. The multi-positional support holder set forth in claim 1 wherein said gauge mount has an annular gauge receiving disk portion, a central hub extending from said disk portion, an annular recess in said hub for select registration with a portion of said control rod.

6. The multi-positional support holder set forth in claim 1 wherein said means for adjustably positioning said control rod in said armature comprises, a rotatable hub fitting threadably disposed within a free end of said armature, said hub fitting in communication with said control rod.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(5) Referring to FIG. 1 of the drawings, a dial holder 10 of the invention can be seen adjustably secured to an electro-magnetic base assembly 11, having a base 12 with an on and off switch 13, an upstanding mounting rod 14 with an adjustable instrument retention rod engagement bracket 15 thereon. The electro-magnetic base assembly 11 is well known and understood within the art, having an electro-magnet with a source of power and can be found within the industry providing a portable stabilized attachment base support for a variety of instruments and articulated clamping assemblies.

(6) The dial holder 10 of the invention has a main body member 16 with a gauge mount 17 rotatably positioned there within, as best seen in FIG. 2 of the drawings. A tubular support armature 18 having a control rod 19 extends from and is secured to the body member 16, as will be described in greater detail hereinafter.

(7) The tubular support armature 18 is slidably secured through the adjustable engagement bracket 15 on the mounting rod 14 by a compression friction fitting 15A as is common within the art. This orientation allows for repositioning of the tubular support armature 18 in relation to the base as needed. The dial holder 10 main body member 16, best seen in FIGS. 2 and 3 of the drawings, is generally annular with a contoured flare upper gauge mount receiving portion 19 with an annular recess at 20 therein, defining an upstanding perimeter retainment flange 20A there about.

(8) A central bore at 21 extends centrally through the body member 16 defining an annular side wall 21A. An oppositely disposed annular recess area 22 is centered about the bore 20 within its lower surface, as seen in FIGS. 2 and 4 of the drawings.

(9) A threaded mounting fitting 23 in the annular side wall 21A receives and secures a corresponding exteriorly threaded end 18A of the tubular support armature 18.

(10) A control rod access opening at 24 extends from the fitting 23 in communication with the central bore 21 allowing the control rod end portion 19A to be selectively advanced into the bore 21, as will be described hereinafter.

(11) The gauge mount 17 best seen in FIGS. 2 and 4 of the drawings has an annular disc portion 25 with a central hub 25A extending therefrom. The hub 25A has an area of reduced annular dimension forming a recess engagement surface 26 there about.

(12) A plurality of apertures A extend through the perimeter of the disc portion 25 through which threaded fasteners F extend to secure a measuring gauge 27 thereto. The gauge 27 is circular having a gauge face 28, and in this example an extending probe assembly 29. The gauge mount 17 attached to the gauge 27 is rotatably positioned within the bore 21 by the hub 25A and is retained by aperture disc 30 fitted within the lower surface recess area 22 by an integrated fastener F.

(13) The control rod 19, end portion 19A is of reduced diameter that extends through the control rod access opening 24 for selective locking engagement with the recessed engagement surface 26 of the hub 25A.

(14) The oppositely disposed end of the rod 19 is engaged by a rotatable hub locking adjustment fitting 32 threadably positioned within the free end of the tubular support armature 18 as best seen in FIGS. 2 and 3 of the drawings.

(15) It will be evident from the above description that when the adjacent locking fitting 32 is rotated (by user) the control rod 19 will advance within the tubular support armature 18 and correspondingly engage the hub 25A locking the gauge mount 17 and attached gauge 27 in place within the main body member 16. Correspondingly to release the hub 25A, the fitting 32 is rotated counterclockwise releasing the pressure on the control rod end 19A, allowing the hub 25A and attached gauge 27 to freely rotate within the body member 16 for repositioning as needed. Orientation of the gauge 27 is therefore achieved by movable axis adjustment defined vertically via the rod 14, horizontally by the armature 18 through the compression fitting 15A, as well as rotatably by the gauge mount as hereinbefore described.

(16) It will thus be seen that a new and novel gauge holder for an electro-magnetic base has been illustrated and described, and it will be apparent to those skilled in the art that various changes and modifications may be made thereto without departing from the spirit of the invention.
