Abstract

225,011. Schneegluth, W. Oct. 4, 1923. Clock-work actuation. -In apparatus for regulating the temperature of furnaces &c. of the kind in which a pyrometer 1, Fig. 1, controlling a movable contact 3 is associated with maximum and' minimum contacts 6, 5, the temperature is adapted to be varied according to any predetermined timetemperature vector by effecting an adjustment of the maximum and minimum contacts in the course of the heat process by means of a mechanism driven by a clock-work. In the construction shown in Figs. and 3, a rack 34 carrying the contacts is driven in one direction by means of a disc 48 mounted on the spindle 47 of the hour hand and carrying a number of adjustable projections 49 for engaging the continuous teeth of a wheel 50, the spindle of which carries a, pinion 52 engaging the rack 54 and also a ratchet-wheel 51 co-operating with a pawl. A similar glaring 56, 58, 59, 60 provided with a ratchet-wheel 57 drives the rack- 54 in the opposite direction, one of the ratchet-wheels 51, 57 running free while the other is driving. In this way any sequence of adjustments can be given to the rack 54 and the contacts 5, 6 carried thereby.
