Pyrometer; dilatation instrument. Mahogany base 315x165x60 with drawer for accessories. On this is a marble slate 285x140 with 2 brass pillars. The expansion rod is placed in these pillars, fastened by a set screw to one and sliding in the other. The moving end pushes on a lever which via a toothed sector and gear turns a pointer, indexing on an enamelled scale 0-60 (antique clock dial?). A heat expansion of app 1,5 mm moves the index 0 to 60.Ref: Det phys Cab vol 2 p 56, pl 17 fig 7.Not signed, but likely made by Pixiic1820 (g)
