Also if desired, the hub may be countersunk atv its inner end as indicated at 42 to receive the forward end of the screw sleeve 41. The rearwardly extending web 36 of the pointer overstands the forward offset of the case, thus hiding the same from view.

The invention is applied by simply slipping the open inner end of the hub over the projecting end of the Shaft of the condenser or other instrument until the case bears flat against the panel or other supporting surface 43 and then y tightening the set screw 18, after the pointer has been set to accord with the position of the instrument. As the hub is journaled in the case, the case can be supported in suspended relation from the hub after the hub has been.

properly attached to the instrument shaft. Preferably, however, the case is independently supported as by means of headed pins 44 extended from the front of the casing through openings provided'in the panel and havingsplit ends bent over the back ofthe panel to. secure them in place.

The ratio of the intermeshing discs attached to the knob and hub is preferably such by manipulating the hub. Also, when desired, more rapid adjustments can be secured by imparting a more extensive or contmuous motion to the knob, the exposed rounded head of the-knob facilitating bbth such adjust ments. As the casing is relatively thin and flat, the device lies close against the panel and because of its generallyL ornamental character, adds a pleasing and finished effect. As the device consists of but few parts and those mostly lightpsheet metal, the same can be built quite i gaged withf of thejcollarl inexpensively.
