AIB-MOISTENEB.

Applicetio To all 'whom 'it may concern:

Beit known that I, Eni J. BUsiinY,a citizen of the United States, and a resident of New York, countyA and V State of ew lYork, have invented certain new and use ful improvements in Air-Moisteners, of which the following is e full, clear, and'exect descri tion. r

. .is invention relates more particularly to the meansfor Savin gas and for cleaning the cylinders of geso enevexplosiveengines of carbon.

The primary object of the invention iste provide a simple and eiiicient means which 5 may be readily applied to gasolene .engines of automobiles or other vehicles without chen 'n r the construction of the suine, and by wich a mixture of air and' water vapor -maybe combined with 'the explosive mixture between the carbureter and the cylinder. or cylinders of theengine therehyeconomizing in theuse of gasolene and at the seme time increasing the speed and causing the carbon deposit in the engine cylinders to be auto niaticallyl'remove o v A further object of the invention is to `provide an attachment or apparatus which is inexpensive to-nianufaoture. and which.

may be readily made and assembled and ap'- pliedto various'kinds of engines as ordinerily constructed,

With these and other objects in view, the invention will be hereinafter more particudescribed with reference to the eccomiaenyng drawings, which" form e part of i3 speciiication, end 'will then be (pointed out in the claims at the endoi` the escriptin.

The engine 10 has one or more cylinders 11 and is provided with the usuel carburetor 12 having a throttle which may be operated by a, creek 13, the latter 'being operated by 640 a rod 14. Above the carburetor is an intake or manifold 15 which is connected to the cylinders. The parts thus described may be oi the usual or of any preferred construction. 0 A tank 17 may be attached to any conven- 'e5 lent' place on the automobile and is here shown as being secured by brackets 18 to the dashboard 19. This tank is connected by e, pipe 20 to en automatic controller or con trolling valve 21, which latter is held to the manifold 15 to control the supply of air and vapor to mix with the ex losive mixture from the carburetor as will present] described. The tank 17 comprises a cyliii ricnl casing or body 22 of any suitable material 75 and of anyV desired size to the lower end of which is held n bottom or cap 23. A tube 24 connects by 'a coupling 25 or otherwise to the pipe 2O and said tube 24 extends up through the 'bottom of the cap 23 and is e0 lflared at its upper end, as at 26, to forni a seat for the end 26 of avtu'be pipe or momber 27. The pipe 27 is provided with e coverin or Casin 28 of blotting paper or other liquid absorbing material and at the upper 55 end thereof said pipe is cut away, as at 29, to provide inlet ports for said pipe, said `dl'isoi'bent material being in the form of e tube und resting at its lower end on the upper edge of the flared end 26 of the .tube'24 9 0 and at its u per end being flush with the lower lips o the ports 29 and `serving by capillary attraction to carry lthe water to vthe upper edge of the absorbent materiel. .The tank is adapted to be filled with Water to a certain height somewhat below the upper edge of the tube 28 und is provided with4 en overflowr opening 30 which regulates the height of the water, said o ening bein also utilized if Adesired to lill t e tank wit ter. The` wetei:` absorbedby the cover or tube 28 is carried to the openings` 29 in the ltube or member 27 end is picked u by air entering openings 31`in cap 32 oi t e tank f `end ipening 30 in tank and ownwardly through openings 31 'being used if desired for the pipe 27 se' iii The vacuum created by the engine prmotor in the pipe 27 draws 'air through 30 and 31 into the upper partof'the 'mkihmughihnpoxeeemdmmgiome bodyand passes into ng the tank with water instead ofropenmg 8 thebpenvic stem 5() it is much simil-ler to make a sharp bend over the lower lips of the ports 29 the air will by friction pick up the water vapor from the upper edge of the absorbent. material und the moist air will pass into the pipe :7 through said pipe to the pipe or connection 20 and to the automatic valve 2l. The cap 32 may have teats or depressed parts 33 which are adapted to enter openings 34 in the cylindrical body 22 of the tank and by which said cap is adapted to be detachabl y held to said body.

The automatic controller or valve 21 coniprises a. casing 35 the upper and lower ends of which are threaded and to the threaded portion at the upper end is held a nipple or member 3G and to the threaded lower end a similar nipple or member 3T. lThe pipe 20 may be provided with a flange, at 38, and may be held in sealing contact with the upper end of the nipple 36 by means of a coupling or nut 39 or otherwise, the nipple 37 of sind valve or controller being threaded at one end, as l0, and directly engaging a threaded opening in the manifold 15 to adapt any air or moisture passing through said controller or valve to unite with the explosive mixture from the ca rbureter and to pass with said explosive mixture `to lthe engine cylinde" or cylinders. lThe casing or body V35 has an enlarged chamber l1 at the lower portion thereof and adapted to move in `said chamber is a tubular valve member or piston 42. This valve member l2 has an enlarged poi-tion 43 and a reduced cylindrical portion 44. The enlarged Jortion 43 provides a shoulder 45 against w lich one end of a spring 46 is adapted to be seated, the other end of said spring resting against aV tapered portion 46a of the'n'ip le 3T and tending normally to force the va ve member 42 upwardly. The reduced ortion 44 ot' the valve member l2 is guided at its upper end in the opening 7 and at the bottoni of said opening is a shoulder 48. A metering valve or head 49 is held to a stein or pin 50. The valveyl9 tapers npwardl., so that at the point where it joins the than the lower portion of said valve. The stein and valve are held stationary within the casing and the valve member or piston 42 is adapted to move relatively thereto. The metering valve stem 50 is provided with an enlarged portion 51 and with collar oi disk-like parts 52 and 53. The disk-like part is pr vided with openings 54 of any desired number and size, Said openings also passing through the disk portion The flange or disk-likeportiogi 53 i's held between a part of the nipple or member 36 and the 4upper end of the casing` or 'body 35, while the disk or member 52 its neatly within the upper end of said inembei- 35, the latter being enlarged at this point so as to properly centralize the valve 49 within the body 35, it being understood that between the various joints where desired, packing may be einploycd to further assist in making the parts tight.

Duringr the normal action of the tank or receptacle 22 the controller or valve 2l among other things regulates the volume of vapor delivered to the Vmotor in an entirely automatic manner. The nipple 40 being.' screwed into the intake manifold above the throttle it will be apparent that when the throttle is closed with the motor ruiming, the vacuum in the manifold is at its hi liest. Thisl vacuum acts against the projecten areaJ of the lower end of the piston or valve mem? ber 43 and pulls it down against the force of the spring l5 and in doing so causes the small part of the member 43 to telescope or move alng the conical end 49 of the metering pin or stern 50 thereb shutting ofi' the vapor to the motor. As the throttle of the motor is opened, the vacuum in the manitold decreases and therefore the spring 45 forces the piston or member -l3 to rise thereby admitting vapor and air to the motor in volumes proportionate to the vacuum in the intake manifold. It should be borne in mind that the controller 21 is always fed nothin r but water vapor and air by the tank 22 during the normal operation of the invention and that this 'apor in .passing through the holes 5l in the metering pin 50 is broken up still finer due to the high velocity of the vapor through the numerous small diameter holes; and finally just before entering the motor the vapor is broke-n up once more in passing between the ed e of the. conical end of metering pin 50 an( the edge of the eounterbore of the. piston or valve iiiembci 43, the shape of the opening between the metering pin and the piston being always similar to a4 venturi which in itself is an excellent means for vaporization purposes. The vaporization or atomizing of the water is thus done entirely mechani- `alllv and is fed in this state into the ina-ni- It is apparent that the vapor is broken up three times before it gets into the motor thereby reducing the lpossibility of condensation en route to the cylinders; that the volune of vapor delivered to the motor is governed entirely by the engine itself; and that when the motor is stopped, the piston or valve member 43 is foi-ced upward by the spring 45 until the small part 4.4 thereof telescopes over the shoulder 51 of the metiering pin 50, and the downward action of thepiston is checked by the dash pot formed by the chamber 41, there 'being an escape for any 'air or gas in the chamber 41 about the part 44 or by a vent through the casing 35. Theiefore when you crank the motor on a throttle which must alwa s be almost closed you are not admitting f se air which from creeping uplwardly and partly ory the tank and valve cooperate with each other and that the process of atomizing or vapor-icing is not complete until the vaporV passes through the controlleror valve 43.

In case it is desiredto cleanYY the engine cylinders thoroughly should they become dirty through deposits of carbon, etc., and when first attaching the invention to the engine already in n'se, the invention may be arranged to have a. scavenging effect. To secure this result means is provided whereby s. much larger quantity o the water or va. or may be caused to pass to the engine cy inders. The pipe 27 at its upper end is provided with a transversely extending pin or rod which also assesgthrongh a cap 56, formin a closureV or the er end of the pipe 2 The. in 55 normal y rests in the bottom of a V-s a ed groove 57 fr-med in the yupper edge of t e reduced art 58 of the cap 32. If Vthe cap 56 with t e pin 55 is given a rotaryl movement, the pin will ride up the side of the V-shaped groove 57 and this will raisethe tube 27 and cover 28 so that Water within the tank will pass di rectl into the flared portion 26 of the pipe or tu e 24. A spring 59 is located about the tube 27 and tends normally to keep the -lower end thereof seated against the flared art 26, said spring havin one end resting against the under sur ace of the cap 27 and its lower end against the edge of the cut-away part forming the openings 29 for the assage of the vapor in said tube and serv ng also to keep the absorbing tube 28 wholly covering t e ports 29. The water passes to the controller valve 21 and in its Vpassage therethrough will be broken up first by the holes 54 in t e metering pin 50 and is then converted into a s ray 1n passing between the sharp edge o the conical part 45 and lower edge of small part 44 of the valve member or piston 42. After the water is converted into a spray it is caused to pass into the gasolene mixture in the maniiold 15 and from there into the'I cylinder where it is converted into steam. By this means the engine may be run very rapidly and the steam `created by the moisture will tend to' loosen the carbon deposit, which latter will in turn be thrown out with Ythe exhaust gases.

It will be understood that instead of the pipe 20 with the mixture of vapor and air passing to the controlling valve 21 to mix with the explosive mixture from the can bureter without preheating the said mixture from the tank may be heated at any desired point so that the mixture may be in the form of steam before it reaches the en ine cylinders.
