Mounting system for infrared tubes

In combination:

• first and second axially aligned insulator mounts spaced apart a given distance and each formed with an axial through-bore,
• an elongated tube containing a coil to be electrically energized,
• first and second insulator plugs on the ends of said tube and each having an axial through-bore,
• first and second bolts having their heads within said tube and their shanks extending through said respective plug bores and projecting endwise through said respective mount bores,
• respective first means on the bolts for holding the ends of said coil beneath the heads of the bolts and for holding the bolts against movement relative to said plugs,
• a spacer sleeve on the shank of the first bolt and extending into the bore of the first mount, and
• respective second means threaded into the outer end of the shanks of the bolts for gripping an electrical lead, the axial distance from the outer end of the second bolt to the outer end of the first plug being less than said given distance and the thickness of the sleeve being sufficient to permit the tube to be removed after removal of said second means and the sleeve by first moving the tube axially toward the first mount until the second bolt is free of the second mount, then tilting the tube by way of the play of the first bolt in the bore of the first mount, and finally sliding the tilted tube away from the first mount to free the first bolt therefrom.
