FLUID-FEEDING APPARATUS.

Application filed January 16, 1915 am we, .loI-IX C. W. GRETH, shurgh Pennsylvanir, 11ml siding at; Oakmont, 11in, have invented certain new "l IEMPlOYQElKCTltS in FluirlFee ing (1 which the following on relates to the propojt-ionel "oral liquids, and is more pmieable to the feeding of liquids purifying zoparutus, course applicable to man ob is to ellloiently employ and more particulerl to w ith certainty, and t ovoid 7 of 'zhemioal reagents into he water.

the tank (1} becomes again filled to the level thereof. ll e also provide a supply of reagents in the "essel (9), emptying by pipe (10} into a smell receptacle (11) Where the level is maintained by the use of float (12) operating the valve This vessel (11 is connected by the siphon (1%) to a receiving vessel (l5) wherein it clips nearly to thehottonr Whilein operation the vessel (15) ove flows into the ehzunber (3) thus deliverthe chemical reagent without passing tl'irough on part of'the Water siphon pipe li o connect the apex of the siphon pipe (1%) a sma l :iir pipe (16), to the main vhon (l) at an operative point and y no?" the top of the long leg. It. on that the siphon will internal {tent-1y, 31ml 1 through the long I the pressure will be recluoerl in the tile bond (5) and in trrir. will reduce H SSIUQ n the siphoo (H), llltH'v'liljI port of the luuud in the small receptacle (15) to he (ll'ilWR up into the siphon (1%) thervupon the siphon (it) will begin bend of siphon (lll. and break that siphon. blnlilillifj also tic iullow oi the reagent. Thus the reagent is iR-il!'()\lll(f U(l without pussiug' through the writer pipe :uul mounwhile the bottom and of the lUHfI leg of siphon (ll) is not exposed. and therev is umriiere any opportunity For reaction and the wonsoquvut evnporutimi :uul :u'cumulntion and deposit of solid nutter to interfere proportional introduction of water fonts.

liming thus Uzmrrior-(il ou inn ion :lilil i lusi ato l in uso, what We claim is the following:

1 A fiuid feeding device including a main siphon for; Water, and asiphon for feeding reagent controlled by'the action of the main siphon, the two siphons having independent outlets, substantially as described. w

2. The combination of receiving tank, a,

siphon therein adapted to intermittently empty the same, a receiving vessel, a fluid reagent supply vessel, and a siphon adapted to empty the same, an air pipe connecting the two siphons, and means to prevent entry of air in the long leg of the reagent siphon.

3'. The combination with water supply vessel, a receiving vessel'and a siphon adapted to intermittently empty the supply vessel,

of a second supply vessel for liquid reagents,v a siphon adapted to empty the same, a supplementary vessel in which is immersed'the long leg of said reagent siphon, and means to start and stop the reagent siphon by the action of the water feeding siphon.

1ng siphon, substantially described.

v 4. The combination with a Water supply vessel, a receiving vessel, and a siphon adapted to intermittently empty the supply vessel into the receiving vessel, of a reagent tank, a connected constant-level reagent feedingtank, a siphon connected to said reagent feeding vessel, a, supplementary receiving vessel, and having the long leg of the siphon constantly immersed therein, and an air pipe connecting the apex' of the reagent feeding' siphon with the Water feed- En'wm O.
