THEREre several advantages to be gained by the employment of a mechanical device for carrying the electrodes used in making contact with the scalp in electroencephalographic examinations. Any method using gauze or other types of bands to hold the electrodes in place is uncertain and unwieldy. The technic which utilizes collodion or similar cementing material to fasten the electrodes is somewhat slow and for best results requires a skilled operator to apply and to remove the electrodes. There is a need for a means of shifting pairs or groups of electrodes rapidly to any part of the skull, as in delineating a tumor. In the interests of obtaining maximum cooperation from the patient, especially with children, the time of examination should be kept to a minimum when possible and the necessary record obtained rapidly.

With these considerations in mind, work was undertaken to develop a mechanical device which would aid
