A handle bracket 40 provided with apertures 41 and 42 rests upon lnuts 28 `rests 38 and 439, the studs 3 and 4 projectingi through said apertures, and nuts 43 and 44 screw on the endsof said studs against the bracket and clamp the bracket in position. A handle v45 is secured to the upper ends of bracket 40.
A stud 50 of copper or other suitable material ofthe proper coefficient of expansion, heat conductivity, melting point and specific heat, is welded or otherwise secured to lthe top of the'base 1 at' the rear thereof and projects upwardly into a recess 51 formed in the upper rear part of cover 35 through :en opening 52 at the bottom of said recess in said cover. A unitary member 55 of my circuit controller, including a base 56 and studs 57 and 58p, is secured to the top of the hase 1 at the rear thereof by means of screws .79 extending. through apertures 60 in hase 5G and screwing into base 1, a spring washer 61 and a washer 62 being interposed .between the base 56 and the head of each of said screws. The hase 56 is curved rearwardly between the studs 57 and 58 to fit rearwardly around the stud 5 0 so that the studs 57 and 58 stand up respectively at the sides of stud 50 through opening 52 and recess 51.

A. threaded shank 85jextends vertically from the top of stud 5 0, and an internally threaded sleeve SG screws on said stud. The sleeve 8G is also externally threaded and an internally threaded ca .8 7. screws on thesleeve 86. The cap 87 liasa conical top 88 forengaging the under side of arm 68. A stud 90 projects radially from the lower edge of sleeve.86, onwhich stud an indicator 91 telescopes.
