(C1. 123--1V19) My invention relates to improvements in air intake and mixing devices for the carburetors of internal combustion engines. The object of the invention is to provide effi 5 cient, inexpensive means ‘of the character above indicated which may be readily incorporated with present day carburetors as vpart of the buretor and intakemanifold 4, said unit being constructed and arranged as follows: ‘ ' The basic element of the unit 6 is a plate-like air jet member ‘I ?tting between said ?anges '2 and 3 and having a central aperture 8 therein 5 corresponding in sizewith the bore of ‘the con duit VI and manifold 4 and registering therewith. equipment thereof to automatically vary the mixture drawn from the carburetor in accord A pair of inlet ports l0, forming'air jets,rare ance with different operating requirements, as, for instance, in hot or cold weathenand when the engine is hot or cold, ‘and which embodies devices for effectively breaking up particles in the mixture which have not been completely va porized and is equipped to thoroughly ?lter'the spectively, said ports extending tangentially to 10. auxiliary air, , ' appear when the succeeding description is read with reference to the drawings’. accompanying and forming part- of this speci?cation, it being 2O understood that the invention resides in vthe de tailsof construction and combinations of parts illustrated in said drawings, ‘speci?cally treated in said description, and de?ned in the claims appended hereto. 1 . Figure 1 is ‘a ‘fragmentary view in side eleva tion illustrating a preferred embodiment of the invention, ‘ Figure 2 is a View in top plan, parts showing 30 in section, . , ' . Figure 3 is a view in vertical transverselsec tion taken on the line 3-3 of Figure 2 looking in the direction‘indicated by the arrows, Figure 4 is asimilar view taken on ‘the line 4—4 of Figure 2 looking inthe'direction of ‘the arrows, the aperture 8 vand opening thereinto in oppo site directions on opposite sides thereof but in a common horizontal plane. Within the member 1 is a fan ll suspended from across bar ‘l2, for rotation in said plane, by means of a screw bolt 15 I3 passingthrough the hub l4 of said fan and Y ‘ Other objects more subordinate in naturewill In said drawings:.— formed in oppositesides of the member ‘I, re ‘ Figure -5 is a View in transverse section taken on the line 5-5 of Figure 4 looking downwardly, 40 and Figure 6 is a View in top plan of the fan mount ing. Referring to the drawings by numerals, in the illustrated embodiment thereof my invention has been shown as applied to a down-draft type of carburetor, the outlet or discharge conduit l thereof being shown only since the remainder of the carburetor is unimportant as regards a proper understanding of the invention. The con 50 duit i has the usual flange 2 thereon for bolting to the corresponding ?ange 3 of the usual intake manifold 4 having the throttle valve 5 therein. According to my invention an air intake and mixing unit 6 is interposed between the ?anges 2 and 3, or in other words, between the car into said bar. 'The cross bar I2 ‘is, part of an open frame !'5 disposed on the ‘member ‘I and shown in-part in Figure 6. Disposed on top of the frame l5 is a similar frame I6 from the inner edge of which a plurality of pairs of ‘op posed baffles lr'l extend into the conduit 1. The ba?ies l1 and. frame l6 are formed of thin metal, thebaf?es with shanks I8 terminating in rounded button-like ends I9 and twisted to dispose said ends 19 in planes oblique to the horizontal,.the ends of each ‘pair of baf?es being twisted in oppo 0 5 site directions and located in a circular group concentricto the axis of the fan H. Below the member ‘l'is av ?lter screen 25 formed ‘of a sheet 30 of any’suitable reticulative' material and. having its edges interposed between said member ‘and ‘the ?ange 3. The member 1, frames l5 and I6, and the ?lter screen 20 are clampedbe'tween the flanges 2 and 3 by means of bolts 2| and nuts 35, 22 thereon arranged at suitable intervals around said ?anges. , _ v M v ‘At one side of the described unit 6 is an air control unit 23 comprising a closed cylindrical container 24, of any suitable metal, suspended from-the ?ange 3, preferably, by means of a bracket 25 ?xed to and extending from the con tainer 24 and clamped to the flange 3 by means of one of the aforementioned bolts 2| and nuts 22. Extending into the container 24, through the top thereof and at'the side thereof opposite to the unit 6, is a vertically disposed air intake pipe 25 spaced slightly at its lower end from the bottom of said container. Extending from the top of the container 24, at the side thereof op posite the pipe 25, is a pair of discharge pipes 26 suitably connected to the member 1 to discharge air into the aforementioned ports Ill. The con tainer 24 is designed to contain oil to approxi mately the level indicated by the dotted line 21 55 2,119,927 in Figure 4. Intermediate the oillevel 21 and the container ends of the discharge pipes ,26 is a plate-like splash guard 28 extending from the wall of the container and suitably secured thereto in horizontal position. At one side thereof a glass sight panel 29 is suitably secured to the container 24 over a sight opening 35 provided therein whereby the level of the oil in the con tainer may be always ascertained. , .170 . Referring to the operation, under the suction ized with up-draftlcar'burétors by merely revers ing the position of the described unit 6. ~ , Manifestly other modi?cations, than that above indicated, may be resorted to- without departing ' from the inventive concept and right is herein reserved to all such modi?cations falling within the scope of the subjoined. claims. ' What I claim is: 1.‘ The combination with a carburetor ‘and the ‘intake manifold of an internal combustion en created inthe intake manifold air is drawn into 7 gine, of an auxiliary air supply and mixing unit the member 1, and, hence into :said manifold, 'in the line of connection between said carburetor . auxiliary air being cleaned or ?ltered by its pas member having a plurality of jet forming air in through air intake pipe 25"the oil in the con—' and. manifold comprising a ring-like member, a_ tainer 24, discharge pipes 26, and ports In, .this vfan vrotatably mounted in said member, said 15 sage through the oil in thecontainer' 24. Mani; let ports therein adapted under suction created festly the quantity of auxiliary air introduced into _ in said manifold to discharge jets of air against the manifold 4 is determined primarily by the said fan whereby the latter is rotated, a plurality speed of the engine as controlled by the throttle of baffle ?ngers extending inwardly of the mem valve 5 so that when the engine is running at ber over said fan, and means for introducing aux 20 , high speed, the throttle valve 5 being well open, iliary air to said ports comprising an oil con-j the quantity of air introduced is increased and tainer through which said auxiliary air is passed. 2. The combination withla carburetor and the the mixture from the carburetor corresponding ly thinned thereby conserving fuel as will be intake manifold of an internal combustion en gine, of an auxiliary air supply and mixingunit 25 manifest. On the other hand as the engine de celerates under, closing movement of the throttle in the line of connection betweenrsaidv carburetor valve 5 thequantity of auxiliary air introduced and manifold comprising a ring-like member, a in the mannerdescribed is cut down. As the fan rotatably mounted in said member, said mem auxiliary air is drawn into the member 1 byway ber having a plurality of jet forming air inlet ports therein adapted under suction created in 30 of the ports I!) it issues from said ports in the form of jetsdirected againstthe blades of the fan said manifold to discharge jets of air against said l~ ; fan whereby the latter isjrotated, a plurality of _I I’ and causing rotation of the latter in a direc baffle ?ngers extending inwardlyof the member ‘ tion to draw ‘or accelerate discharge'of the mix ture from the conduit‘l. vSuch discharge of the over said fan, and means for introducing aux um UP. mixture, however, is opposed by the battles H iliary air to said ports comprising an‘ oil container which, together with the fan ll, tends to break up particles of gasoline in the mixture. which have not been completely vaporized in the car buretor, mixing chamber. Such breakingjup of to the mixture is further facilitated by its passage through the ?ltering screen 20 as will be clear. . As will be understood, the oil in the described air-control unit 23 functions to regulate the quan tity of air passing through said unit under differ ent temperatures obtaining. For instance, in cold weather, when a rich mixture is desirable for starting and warming up the engine, the oil is thicker and retards the passage'of air there through. In warm weather, the oil being thin do ner, there is less resistanceto passage of the air therethrough as will be clear. ,' . The operation, construction and advantages of _my invention will, it is believed, be clearly under stood» from the foregoing-without further ex planation. . i V H ; It may be stated, however, that although the invention has ‘been shown and'described as ap plied to a down-draft carburetor, it may be util through which said auxiliary air is passed, and a ?ltering screen in said member below said fan. 3. The combination with a'carburetor and the intake manifoldpf an internal combustionvlenj gine,‘of an auxiliary air supply and mixing unit in the line of connection between said carburetor and manifold'comprising a ring-like member, a ‘fan rotatably mounted in said ‘member, said member having a plurality of jet formingair-"ina let ports therein adapted under suction created 115 in said manifold to discharge jets of ' air against said fan whereby the latter is rotated, a plurality‘ of baffle ?ngers extending'inwardly of the mem ber over said fan, and means for introducing aux iliary air to said ports comprising an oil recep-e tacle through which said auxiliary air is passed, .an air inlet pipe extending through the topof the receptacle into the. oil, conduits extending between the top of the receptacle and said ports, and a splash guard in the receptacle between the level of the'oil and said conduits.
