GAS-SAVER FOR INTERNAL-COMBUSTON ENGINES. l

App1icaton filed August 10, 1916. Serial No. 114,235.

To all whom it may concern vBe it known thatA we, ANDREW J. HANsGEN :1nd EARL G. OvERsifrrii, citizens of the' provements in Gras-Savers for Internal- Combustion Engines; and we do declare the following to be a ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this speciication.

The present invention relates to improvements in means for supplying moisture to the explosive mixture preparatory to its introduction to the engine cylinders of an internal combustion engine, and pertains more particularly to the arrangement and provision 'oi' such means as will lenable a more active or sensitive and more eiiicient mixture to be produced..A The moisture, according to the present invent-ion, is introduced into the air before the latter enters the manifold of the engine whereby there is an intimate mixture oil the moisture, the air and the vapor of gasolene or other liquid or fluid employed.

The invention has for its principal object to provide an improved means of the class above referred to whereby moistened air will be taken from the upper part of the radiator at a point above the normal supply zone making it impossible for water to be introduced into the mixture.

A further object of the invention consists in providing an adjustable air supplying nozzle by means of which atmospheric air can be introduced to the moistened air at a point intermediate of the radiator extremity of the supply pipe and the connection oi the latter with the manifold.

A still further object of the invention consists in providing an adjustable valve accessible to the operator of the car by means of which the amount of supply of the inoistened mixture may be readily controlled when the engine is in operation.

A further object of the invention is to produce a simple and inexpensive device which will effectively produce the results de'- Specication of Letters Patent.

- conical-shaped head or nozzle 18 into Patented Jan. 6, 192,0.

sired, .the parts of which can be easily adjusted according to the varying conditions under which the engine is running.

The inventionalso contemplates the provision of means whereby 'any local moisture that may have formed through condensation after the engine is stopped will drain itself out of the piping and prevent any clogging or obstruction of the parts.

Vith this and other objects in view, the invention consists in the combination and arrangement of parts more fully set 4forth in thefollowing speciications, illustrated in the accompanying drawing, and more particularly pointed out in appended claim.

In this drawing The figure isa side elevation of an inten nal combustion engine with` the present 'invention applied thereto, the radiator head and front portion of the machine being shown partially in section.

Referring now to the drawing,let the numeral 5 designate the internal combustion enoine; 6 the radiator; 7 the carbureter; 8

the manifold; 9 the exhaust pipe and 10 the inlet from the carbureter to the engine.

- In order toobtain the desired moistened air from the radiator 7 and avoid the possi* bility of having water mixed therewith, an extra sleeve or extension 11 is secured to the sleeve 12 at the upper portion of the radiator being screw threaded thereon as shown in the drawing. This sleeve 11y is provided with an exterior thread 13 at its upper extremity which is' engaged by the interior thread of the radiator cap'lt. By the provision of this extra sleeve the space above the normal water level L is materially increased. A pipe 15 having its upper end 16 extending into the upper part of the space provided by the sleeve 11 is employed t0 carry the moist air from above the water level in the radiator to the carbureter inlet pipe 10 of the manifold. The pipe 15 is interrupted at any suitable place 17 and one of the disconnected ends is provided with a which the other end 19 of the pipe extends. Slidably secured to the end 19 isa sleeve 20 carrying a disk member 21 adapted to enter the larger end of the conical nozzle 18. A set screw 22 on-the sleeve 2() provides means for ing of the conical head 18. By thisconstruction atmospheric air is admitted through the flared end of the head 18 as indicated by the arrow A. The amount of air admitted at this point can be easily con- .trolled by suitably adjusting the disk 21 on the pipe 19, and, if necessary, the disk can be so positioned in relation to the head or cone 18 as to completely cut oli the air sup ply at this point. l

A valve 23 is also provided' in the pipe 15 and is preferably located near the connection between this pipe and the inlet 10 to the manifold. Fixedly connected with the valve stem is a lever arm 24: the outer extremity of which is pivoted by 25 to the inner end of the adjusting rod 26, the opposite extremity of which extends through the dashboard 27 of the machine and is provided with a knob 28 accessible to the driver of the car. -By means of this rod 26 the valve 23 can be easily controlled so as to regulate the amount of supply of the moistened air to the manifold.

. Pipe 15 may be formed with .one more'i ports 29 preferably located at or near its lowest level. A single port is here shown by way of illustration but more may be used if found necessary. When the engine lis running and the supply of moistened air from the upper chamber of the radiator is being fedto the manifold, a certain amount of atmospheric air is sucked or drawn through this port. supplementing the air which is taken in through the. head 18. When however, the valve 23 is closed and the engine stopped for any length of time the port 29 serves the purpose of allowing any water of condensation which may have collected along the pipe 15 to drain out, thus preventing the admission of this water' into' the intake 10 of the mani-fold when the engine is again started.

Devices have been used before to draw moist air from the overflow pipe of an automobile radiator for the purpose of mixing with the vapor and air moisture of the carbureter, but, as far as applicant is aware, he is the first to provide means whereby an additional space is vprocured above the normal water level of the radiator. The principal advantage gained by this arrangement is `that the possibility of water spray entering the moist air pipe 15 is precluded by having the upper end of the pipe s0 far removed above the water level.

The adjustable disk 21 coperating with the head 18 provides a means by which the amount of atmospheric air to be introduced and mingled with the moistened aircan be regulated or controlled according to the at mospheric conditions of the weather as, for instance, the differences which exist due to the seasons of the year. There may be times when the drier, colder air of the atmosphere .of moistened air to be mixed with the carbureter mixture entering the manifold, as, for instance, to meet the different requirements of the engine while running over different grade-s or kinds of road, the knob 28 and rod 26 controlling the valve are made use of. It will thus be seen that a finer adjustment and a more sensitive control can be obtained with these two separate means supplementing one another than would be the case if but asingle valve or mechanism were employed for the same purpose.

By adding a mixture of moistened air to the carbureter mixture just as the latter enters the engine a more complete combustion of the explosive materials is effected which greatly diminishes the amount of lcarbon deposit i-n the cylinders and also increases the power of the motor. A

The iniux of cool air as provided for by the present arrangement presents the further advantage of tending to lcool the engme. u A still further advantage is obtained by the use of the control valve 23 viz: the reduction in the amount of suction exerted on the stray nozzle of the carbureter when the control valve is opened.

Having thus described our invention what we claim is Means for supplying moist air to themanifold` of an internal combustion engine comprising in combination a chamber located at the top of a radiator above the normal water level, a conduit connecting said chamber with the manifold, said conduit being provided with an interrupted connection, a nozzle secured upon the extremity of one section of the conduit, andan adjustable disk mounted upon the adjacent extremity of the other section, said nozzle and disk coperating to supply atmospheric air to the said conduit and toregulate the amount thereof. I In testimony whereof we affix our signatures, in presence of two witnesses. j
