This invention relates to improvements in mouth specula and more particularly to an improved tongue-depressor. Its object is to provide a tongue-depressor which is instantaneously removable from the mouth-gag. This tongue-depressor may be adjusted for depth to suit the mouth, and has an oscillatory mounting, leaving the operator free to move the tongue-depressor from side to side without affecting the adjustment of the gag or removing the depressor from its holding means.

The particular advantage of the device is the ease with which the tongue-depressor is manipulated, in and out or from side to side in an instant.

The ratchet on the gag affords adjustment of the mouth to any desired opening. By the pressing of a button on the side, the ratchet is released.

In the hands of my associates and myself, this instrument gives great satisfaction.
