Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . to raise the diaphragm andits pin valve, and hold them up for aperiod of time such as is required bythe main reservoir air to flow throughthe feed valve into the break pipe, andnearly equalize. Tliis peculiarity of the governor, the stopped for a few-seconds, at first was regarded as an un-desirable feature. ;ind it was to someextent criticized; but as time advancesand experience in the use of the E. broadens it is coming to be re-garded as a desirable feature since itcauses the one manipulating the braketo carry the handle in release positionwhile charging, releasing and recharg-ing, which, of course, is the proper onefor these operations. During all the years of our brakemanipulation much annoyances andd;image in tlie shape of stuck brakes,break in twos and delays have beencaused by releasing with the handle inrunning position; and this defect isbeing rapidly corrected by the S F 4governor and E T brake, simply be-cause tile pump does stop, and it notifies. DYNWMITK rSKD OX A IN THESdfTII AFRIC.\N WAR. the engineer by so doing that there hasbeen an error made in other feature treated by our cor-respondent is that of the eflfect on theS F 4 governor of slight leakagethrough the feed valve when the handleof the brake valve is allowed to remainin release position too long, whichcauses the governor to fail to stop thepump when the required main reservoirpressure is obtained. The reason itallows the pump to continue to workrntil the pressure for which the highpressure top is adjusted is obtained isas stated, namely, a very small volumeof fed valve pipe into which a slightleakage can quickly increase pressureand maintain it, above the excess pres-sure diaphragm, equal to that below condition of pressure above andbelow the diaphragm enables the gov-ernor excess spring to hold the pinvalve to its seat, and so preve
