Also it will be seen that even the valve stem that is in the path of the acetate is of stainless steel 50 there is no possibility whatever of any rust getting into the acetate. Furthermore, it will be seen that regardless nut 62 with the upper gland nut 63; the passage of whether the base should have blow holes way through the nipple, of course, registering therein, by forming these passageways in the with the passageway 64 registering with the gland stainless steel, there will be no loss of pressure 63. and the metering of the pump will not be ad 10 nut ' The modification shown in Fig. 5 also shows versely affected. . - Still glancing at the upright 3, Fig. 1, there -will be seen the stationary nipple II which is . a cast iron base having the body- 15, the upright ' ‘l6 and the upright 11, the upright 18 having the stainless steel plug ‘I6’ tightly and permanently E?tted within the cast iron upright and sealed in’ ?tted therein which plug is then drilled as at 18 the stainless steel insert III.
