Abstract
CLAMP FOR PANEL MOUNTING OF GAUGE INSTRUMENTS
Abstract of the Disclosure The stem connection of a back connected gauge instru-ment placed extending partially through an opening in a panel wall is received in an aperture of an elongated clamp plate adapted to span the instrument parallel to the back-side of the panel. A keyed recess in communication with the plate aperture is adapted to interlock with a coopera-tive surface on the gauge stem at a predetermined location longitudinally spaced behind the gauge. A foot of a leg extending integrally from the plate at one end thereof toward the backside surface of the panel cooperates with a similarly extending preassembled thumb screw extending transversely through the plate at the opposite end to effect mounting. The thumb screw also serves to adjust-ably draw and secure the gauge into its mounted position.

is a suitable thumb screw type fastener threaded through the plate near the end opposite the leg and generally parallel thereto, the thumb screw type fastener being screwed inwardly against the back side of the panel. With the ; 30 plate interlocked in position on the gauge stem, the leg -- and thumb screw cooperate in a U~shaped s-tructure spanning the gauge such that tightening the thumb screw draws -tm/J~ -3-,~,., the gauge into its panel mounting relation. The clamp with the thumb screw preassembled in place are essentially a unitary structure free of any loose components, and since both the interlock and the thumb screw are essentially hand operations the use of tools to effect installation become unnecessary.

3~3 Fig. 7 is a side elevation of a panel mounted gauge installation in accordance with a second embodiment hereof.
Referring first to Figs. 1 and 2 of the drawings, there is shown a pressure gauge 10 of a type contemplated for mounting against a panel wall 12 by means of a clamp 14 in accordance with the invention. Gauge 10 is of a well known type comprised of a rear casing 16 generally housing the operating components. The casing is adapted for the con-cealed purposes hereof to be received through a panel aper-ture 18 of size enabling the enlarged head comprised of abezel 20 to be position2d against the panel front face 22.
Contained within bezel 20 are crystal 30 and a dial face (not shown). Optionally, the backside of bezel 20 can either be mounted flush against panel face 22 or where desired tabs ; 15 24 can be utilized to maintain a slight clearance 25 for aiding in subsequent bezel removal.
Fluid pressure from a system to be measured, as repre-sented by arrow 27, is normally connected via conduit to the threaded end of gauge stem 26 extending outwardly through the rear of casing 16. A central passage 28 in stem 26 leading to the operative gauge components communi- ; ;.-r~
cate the pressure for effecting indications of pressure ~ values in a well known mannertobeindicated by a pointer and -~ dial visible through crystal 30. For mounting the gauge in the manner to be described, stem 26 includes a pair of oppositely positioned transverse grooves 32 and 34 formed at an intermediate location between casing 16 and the stem ~; threads.
Clamp 14, as will now be described with reference to Figs. 1-6, is comprised of a more or less flat elongated plate 36 formed of about 3/32nd inch cold rolled steel flanged for strength along its sides 38 and 40O Plate 36 is laterally bent at one end to form an integral offset leg 42 and includes dimple recesses 44 and 46 at the bend for reinforced strength thereat. A weakening cut 48 extending transversely from the ends of oval aperture 50 to the side edges of leg 42 form a breakoff tab 52 which when required - can be broken off to reduce the length of leg 42 as will be understood.

Formed at a location slightly off center in plate 36 is an opening 54 of size sufficient to readily pass the threaded end of gauge stem 26. Co~lmunicatin~ with opening 54 and extending laterally therefrom is a slotted keyway 56 adapted to cooperate with stem grooves 32 and 34 for placing the plate in a rotational and longitudinal interlock with the stem. In addition, bent tabs 58 serve to prevent post-installation slippage of stem 26 from keyway 56. Contained near the distal end of plate 36 opposite leg 42 is a tapped aperture 60 for recei~ing usually pre-assembled L head thumb screw 62. With screw 62 threadedly started into aperture 60, clamp 14 is entirely preassembled as an essentially unitary structure without any loose components.
Installation for concealed panel mounting of gauge 10 merely requires that the gauge case 16 first be backed through the panel aperture 18. The clamp 14 is then mounted onto gau~e ste~ 26 by passin~ the threaded portion of stem 26 through plate opening 54, ~hen keyway 56 is properly oriented in ~osition to embrace parallel stem grooves 32 ; 20 and 34, the keyway is slipped into the grooves to effect ' a rotational and longitudinal interlock therewith. With , the foot o~ leg 42 en~aging the panel backside 59j. th~nb ', ~, screw 62 is tightened down until its distal end also engages panel backside 59. Thereafter, screw ti~htening is con~
25 tinued until bezel tabs 24 reach a flush and firm relation " against panel surface 22 thereby completing the install-'~ ation. Where a shorter leg 42 is required, breakoff tab 52 can be conveniently removed by bending to and fro. The entire installation in this manner can be performed in a , 30 matter of seconds and for most gauges of the more commonly ~
used sizes can be readily installed without the use of any ~' '~ tools.
-'~, In the alternati~e emhodiment of Fig. 7, clamp 14 is ' essentially similar to that descrlbed aboYe but differs therefrom by the replacement of leg 42 with a second thumb ",' screw 64 threaded into pos,ition via a second tapped aperture '',, 66~

free of any loose components and by means of a simple inter-lock connection and a thumb screw adjustment can be quickly and easily placed on the gauge ~or panel mounting thereof.
By this simple yet effective construction, the clamp is significantly less complex than similar purpose clamps of the prior art while at the same time consuming less labor time per gauge installation t~ previously known. The economic advantages of such a construction should therefore be readily apparent.
Since many changes could be made in the above construc-tion and many apparently widely different embodiments of this ~- invention couId be made without departing from the scope `. thereof, it is intended that all matter contained in the drawings and specification shall be interpreted as illus-trative and not in a limiting sense.
