Specification of Letters Patent.

atented Aug. 22, 191.1.

Application filed September 13, 1909, Serial No. 517,399. Renewed February 10, 1911. Serial No. 607,873,

To (di Quito/1n tt may; concern:

Be, it known that I, AifrRno A. Sointvrz, citizen ot the United States. residing` at l)etroit7 countyY ot rayne State ot' tvlichigan, have invented a certain new and uselul lmproveinent in rintiseptic Faucets, and declare the 'following to he a full. clear. and exact description oit' the same. such as will enahle others skilled in the art to which it pertains to make and use the same. reterence being had to the aceompanving drawings, which Yterm a part o't this slaeilication.

This invention relates to Vtaucets tor introducing an anti-septic lluid into a 'lowing stream oit liquid.

lt has tor its ohjeet an improved attachment that is intended to he used with the taucet .shown Vin my Patent No. (3T-MHS; in place ol the ailti-sept'ic mingling attachment shown in that patent l substitute the one hereinz'litter descrilied.

in the drawings :-l `igure l. is a Isectional view showing the device in its assemhled lorm. Fig. 2, is a longitudinal section.

()n the spout l. is arranged a socket' 2 to receive the plug 3, the upper end ol which serves as a stopple Ytor a tank or vessel Lt that contains the anti-septic tluid. 'llu'ough the bottom ot the socket Q is a passage that leads into the spout. 'lhat end ot the stopple which is turned downward in the assembled structure is provided with a screwthreaded cavity 7 into which is screwed a plug S; the upper end o't the plug S is provided with a cavity 9 and the lower end is provided with an extension l1() eoned or needle-pointed, and with a passage Q() leading through the plug and through the extension. The end oit' the needle point engages in a seat lll in a lower plug l2 which Vis also provided with a central passage that extends through the main part of it and partlyY along a. guard extension 13 that terminates the lower end oit the plug. The guard extension 13 in the assembled structure projects into the passage 14. oit the spout and serves to. prevent the liquid flowing through the spout from producing too strong a siphoning action on the tlnid in the tank. Above the plug 8 is a check Valve l5 that seats upward against a seat 16 in the plug t3. A. passage 't7 leads through the side walls ot the plug into the `passage in which the check valve seats Vwith its inner terminal arranged to turnish access o'l air through the side walls to the interior o'lf the tank 4t.

tithout the check valve there is danger that the lluid would he drawn `trom the spout into the antiseptic tank, hut the check valve prevents this. AWithout the passage l? the check valve would he .lilt'cd against its seat' at, all times and no liquid would llow ilrom the tank Llf; the check valve does not seat on the plug 8 so closely lult that liquid will readil)7 pass it when in the po sition shown in l `ig. Q. Under ordinary con ditions o't atmospheric pressure air does not rise in the tank; when the pressure helow the liquid has heen reduced h v the action oit the liquid [lowing through the spout a 'small huhhle ot air will rise through the liquid in the tank` until atmospheric pressures and lirictional resistance equalize the pressures on this liquid.

lnrthe drawing the size ot the passage 117 is exaggerated.

that lA claim is :M-

l. ln a l'xture Alor mixing antiseptic V[luid with a liquid in comhin'ation with a spout provided with a passage tor the main liquid, an antiseptic tank provided with an outlet deliveryY leading into the passage to the main liquid with a check valve therein located to seat hv atmosplniric pressure up ward and. prevent the [low ot lluid into the antiseptic tank, suhstantiallv as descrihed.

2. ln a device `tor mingling an antiseptic l'luid with a liquid in combination with a. spout provided with a passage tor the llow ot the main liquid, an antiseptic tank provided with an outlet leading into the main spout, a check valve in said passage, an air passage to relieve the vacuum in said tank, substantially as described.

In testimony whereol, l sign this specifi cation in the presence ot two witnesses.
