A hollow spot in the or the bore of the hub willbe shown in the diagram by a dip in the diagonal line, and viceversa, a high spot will be shown by a hump in the diagonal of the important features of the recording gage is thatit is inaccessible to the operator and represents the true storyof the wheel fit. An opening is provided at the right of the diagram for the signatures of the wheel fitter and the press man,and the recording of the wheel number. Each record roll hasa capacity of 300 diagrams or ISO pairs of wheels. Therecorder is protected from over pressure by a }i in. hydraulicrelief valve set at about 150 tons. A !/< in. pulsating checkvalve protects the movement, the registering and the recordinghands from sudden fluctuations in pressure. The recordinggage is cut in or out by a yi in. stop cock which may be lockedin the open position so t
