Its correct use, management and care, derived from the author's practical and professional experience .. . lso torturous and rough passages, non-covered or unprotected pipes, incorrect valve setting, tardyvalve motion, etc.; all or any of which tend to cause an appar-ent difference of pressure between the indicator and steamgauge. Where such differences do exist in these pressures, thefault is generally supposed at first thought, to lie with the in-dicator, when in fact it may be due to any of the causesnamed; or may be due to the incorrectness of the steam gaugeitself. Therefore it becomes important that means be taken toascertain how near the gauge and indicator agree in denotingthe steam pressure, in order that the amount of pressure lostbetween the boiler and engine may be determined. And Its Appliances. 175 For making- such comparative tests the arrangement illus-trated in Fig. 84, is easily constructed, not very expensive,and is well adapted for the purpose. It may be connected directly with the steam space of theboiler, or may be attached to the steam pipe in any In making a comparative test when the device is attachedto the steam pipe (as shown) it is best that it be done at a timewhen the engine is at rest, and the throttle valve closed in or-der to avoid any fluctuations of pressure that otherwise mightexist in the pipe. J 76 Steam Engine Indicator In the matter of construction the Chamber C. should be ofsuch size as to contain a considerable volume of steam, andsuch chamber may consist of an ordinary four inch cross fitting-,with the inlet and outlets reduced to suit the size of pi
