Seating for the screw spindle and guide means for the sliding contact wire in a glass tube thermometer of round,non-circular or polygonal cross section and containing adjustable electrical contact means for temperature
Abstract A seating for the screw spindle and a guide means for the sliding contact wire in a glass tube thermometer of round, noncircular or polygonal cross section and containing adjustable electrical contact means for temperature control and/or limitation. The seating for the screw spindle provided for setting the required temperature has a pan-shaped bottom and resilient blades forming the sides of the seating, one of the blades having an extension bent over inwards into parallelism with the pan-shaped bottom to form a lug containing a hole in which the lower end of the screw spindle is eccentrically or centrically held, whereas another of the blades is likewise extended but the extension bent over outwards into parallelism with the blade itself. The bend contains an opening and the blade itself a corrugation which in cooperation with the extension and together with the hole forms a tubular guideway for the electrical contact wire.
A seating for the screw spindle and a guide means for the sliding contact wire in a glass tube thermometer of round, noncircular or polygonal cross section and containing adjustable electrical contact means for temperature control and/or limitation, comprising a pan-shaped bottom and resilient blades forming the sides of the seating, one of said blades having an extension bent over inwards into parallelism with the pan-shaped bottom to form a bearing lug containing a hole in which the lower end of a screw spindle is held, whereas another of said blades has an outwardly directed bend followed by an extension extending parallel to said other blade, said bend containing an opening and said other blade a corrugation which in cooperation with the extension and together with the opening in said bend forms a tubular guideway for an electrical contact wire.
