Description
UNITED STATE@ NICHOLAS P. IVLADER, 0F SUN PRMRIE, J'SCNSEBL arrasa.
Specicaton of Letters Patent.
Application. tiled. yFebruary 7, 1910. Serial No. 540,559.
State olf llisconsin, have invented certain new and useful Improvements in Mixers; and .l do hereby declare that the following is a full, clear, and exact description thereof.
My invention has for its objectv to provide a simple, effective and economical mixer or homogenizer, the construction and arrangement being such that air and oil admitted to the mixing chamber' are thoroughly mingled. before being delivered into the combustion chamber, the uniform minture of the air and oil to forni the explosive gas being attained by passing the same through a series of' chambers successively reduced in area, whereby a slight gradual compression of the carbureted vapor is obtained np to a point of discharge, at which point said vapor is expanded.
A further eliicient result is obtained by utilizing serrated or corrugated surfaces, over which the oil and air thin filmer oil will, by capillary attraction, adhere to said surface and permit the air to 'have access thereto, thus thoroughly breaking up and evaporating any particles of oil which may be discharged lintov the mixing chamber. i With the above objects in view, the invention consists in certain peculiarities of construction and combination of parts as fully set forth hereinafter with reference to the accompanying drawings and sequently claimed.
In the drawings Figure l rep aesentsie sectional elevation of a carburcter mixin, r iy chamber embodying the features of my invention, the section l 1-1 of Fig. 2; F ig. 2, a plan/view of the same partly in section as indicated by line 2-2 of Fig. l, and Fig. 3, a vdetail inverted plan view of one of the mixing chamber members detached, illustrating an annular corrugated head against which the oil and air are deflected.
Referring by characters to represents the exterior wall of a chamber-ed casing provided with a bottom head 2 having a centrally disposed intake nozzle extending therefrom, which nozzle projects into. the casing. lllhe mouth of the nozzle is pro ed with a series of annular corrugations 5, which corrugations in this inthe drawings l pass whereby a dornehead being indicated by line stance are formed Aupon a thimble 4C that is secured in any suitable manner within the These corrugations are formed in the upper edge of the thimble with their top edges successively increasing in height to the outer series, the depth of the grooves between the first and second corrugations being greater than the depth of the next groove, completes the series.
A dome 5 is fitted within the chamber of the casing, being preferably a detachable part as shown. The said dome is supported by means of radially disposed ribs 6 which engage the'inner faces of the casing l and rest upon the bottom head 2. The sidewalls 7 of the dome are so spaced relative to the adjacent face of the nozzle and casing as to form channels therebetween, the channel between the being of slightly greater width than the channel between said side-Walls of thedome and the casing-wall l. The bottom edge of the sidewalls of said dome terminates at a distance from lthe bottom head, which distance is equal to the width of the inner channel that is formed between the dome and nozzle. The head 8 of the dome serves as a detlector, against which the air and oil come in contact as it is delivered from the intake nozzle.
As clearlyshown, the inner face of the which, in this4 instance,
centric circular corrugations, the crowns of which corrugations terminate just above the crown of the outer corrugation of the series witlrwhich the nozzle is provided. It will also be observed that these two sets of oorrugations are relatively disposed in such manner that the corrugationsof the nozzle articulate with those corrugations of the dome-head located above the same.
The casing l is open at its upper end and provided with screw-threads for the reception ot the threaded edge of a cap 9, which cap is lynovided with a dischargeV aperture l0 in the formot' a threaded nipple adapted to receive the usual pipe connection, the intake nozzle being internally threaded for the reception or the usual inlet pipe connection, through which pipe connection oil and air are delivered to the mixing chamber.'
The bottom head of the casing 1 is provided with an annular' exterior groove lladapted to receive a small quantity of oil for the purpose of warming 'the mixing chamber ilatented Get.. i8, 191@ is provided with a series of conunder certain conditions, the oil being ignited increases lthe temperature of said chamber, and While l have made provision for this purpose, it Y`is understood that 1n some instances the annular groove may be dispensed with. As shown, the thimblc is constructed from a separat/e p1-ece oi metal and titted Within the nozzle.' This construction is employed for-convenience in manufacture, but it should be understood that in some instances the corrugated edge may form an integral part ot' the intalre nozzle.
As indicated by the arrows in Fie, l, the volume of air and oil when sucked up through the intake nozzle will strike the corrugated surface of the dome head and these corrugations will thus break the oil .into a line spray. As the air is deflected radially it will cause the'oilgto travel in the same direction across the sries of corrugations, being confined thereto by capillary attraction. This thin film 'of oil distributed over the large surface yarea thus :termed causes' the air beine,` passed t-hereover to become fully laden or enriched with the oil vapor, While at the saine time the interrupted surface prevents any of the liquid from being carried farther into the mixing chamber or delivered into the engine.
Should the corrugated vhead become overladen with oil at its outer edges, the same of its own Weight will drop and be caught into the `grooves of the lower cdrmigations and thus being poclteted Will be gradually absorbed by air passing,r thereover, and owing to the articulated position of the corrugations as stated previously, it Will be seen that the air when passinpr therebetween Will thus be ydeflected in somewhat zigzag form and thereby Ainsure the opposing oil laden surfaces being thoroughly subjected to an air hath. The 2gaseous liuid in its travel from the intake nozzle Will be slightly and gradually compressed asv it passes between the corrugated faces. The carbureted air thereafter passes down the channel between the dome and nozzle and is again slightly compressed. At the bottom edge of the dome the air is returned up through the outer channel between the dome-wall 7 and chamber-Wall l. At this point another slight compression takes place until the said air is discharged above the dome into a mixing,r compartment, which is of such areaas to permit the vapor to extend the ull fapacity of the discharge opening.
llv'utilizing a succession of channels as stated, in which channels the carbureted vapor passes in a zigzag form under a succes sion of step-by step compressions, it will be understood that the air is thoroughly mixed with the oil vapor, and after being thor oughly mixed is discharged into -the combustion chamber of the engine in a tgas of bein g evene? and oil are frequently discharged into a' combustion chamber of an engine with uneconomic and disastrous results.
TWhile l have shown and described the mixing chamber as provided with opposing series oi' circular corrugations, it should be understood that thesev corrugations may be 4varied in form and, in some instances, dispensed with, the arrangement oi' channels, however, being the same in each case.
The mixing chamber herein described and claimed embodies the general principles of the mixing chamber disclosed but not claimedin an application fonpatent for carbureters, filed by me March l1, 1909, Se rial No. 482652.
I claim:
l.
