Original application July 22, 1932, Serial No. 623,957. Divided and this‘application Decem ber 16, 1936, Serial No. 116,049 5 Claims. This invention relates to improvements in charge diluting attachments for engine intake manifolds. The present application is a division of my 5 application No. 623,957 entitled “Charge modify ing attachments for engine intake manifolds”. In the above entitled parent application I have disclosed a preferred means for regulating the total flow of a gaseous mixture to the manifold it) together with means for regulating the delivery of such mixture to the manifold in a manner to vary the portions of the mixture supplied to por tions of the charge in varying areas of the mani~ fold. (Cl. 48-180) Pipe 3| leads the diluting air to an annular distributing conduit 40 which may comprise a groove cut in the upper face of the block 35. From this conduit any desired number of ducts 4| lead tangentially into the mixture passage 39, each ‘duct preferably being under the indi vidual control of its own needle valve 42. To pro vide a convenient seat for the jamb nuts 43 for these valves the block 35 may be squared up as shown in Figure 2. 10 As above noted, it will be found that these valves should be adjusted individually according to the requirements of the particular engine. It to the charge regulating attachment which is ?tted to the manifold. It is the primary ob ject of the invention to provide a manifold inlet ?tting incorporating means by which the in coming gas may be apportioned between different parts of the manifold to secure the most desir able results, it being found that the ?ow of charge through the manifold is by no means uni will be found that best results may be secured with one valve relatively wide open and another relatively tightly closed, depending on factors un known at the present time, but probably con cerned with the manner in which the charge moves from the carburetor through ?tting 35 to the intake manifold. 20 I claim: 1. An intake manifold ?tting comprising a block having a central aperture registerable with form and that the incoming gas should be ap the manifold opening, a plurality of ducts open The present application pertains speci?cally portioned about the manifold in accordance with the relative flow of the charge therethrough. In the drawing: Figure 1 is a diagrammatic view largely in side elevation but partially insection showing the de 30 vice of the present invention applied to an intake manifold between the carburetor and the mani fold proper. Figure 2 is a plan view of the ?tting partially broken away to a horizontal section. Figure 3 is a fragmentary detail View taken on CO Cl the line 3-—3 of Figure 2. Like parts are identi?ed by the same reference characters throughout the several views. It is very important in any air or gas admis 40 sion system to control the delivery of the diluting gases not only as to amount but also as to the proportionate amount delivered to different parts of the manifold. Different engines vary as to their requirements in this regard even as between engines of the same make equipped with like car ing tangentially into the aperture of said block, and- needle valve means in threaded connection with said block and individually controlling the respective ducts, said block including a conduit placing the several ducts in communication with each other and comprising a channel in a face of the block externally of the points in said ducts at which said needle valve means is effective. 2. An intake manifold ?tting comprising a block having faces adapted to be clamped be tween the manifold ?anges and having a'central aperture registerable with manifold openings and having a plurality of ducts opening tangentially into said aperture and a channel in one of said faces adapted to be closed by one of said flanges when the ?tting is assembled in the manifold, a . supply pipe leading through said block to the channel, and valve means individually controlling the respective ducts and manually adjustable to predetermined settings, said conduit communi cating with the several ducts externally of said 45 buretors. My improved inlet ?tting comprises a block 35 interposed between the intake manifold ?ange 36 and the complementary carburetor flange 31. The block 35 is‘ preferably made to register with the aforesaid ?anges and is apertured in regis try with the holes which receive bolts 38. It has valve means, whereby to afford controlled com a central bore 39 which passes with a slight re affording communication between the several ducts and provided with a supply connection, and valve seats about each of said ducts between 55 striction at 34 to the intake manifold the charge 55 originating in the carburetor. munication between said pipe and said aperture at a plurality of points about the periphery thereof. 3. An intake manifold ?tting comprising a 50 block having a central aperture, a plurality of ducts opening to- said aperture, passage means 2 , 2,184,767’ said passage means and said central aperture; in combination with a valve member for each duct threaded in said block and adjustable to and from one of said seats, whereby to control ?ow to said aperture at each of the points at which the several ducts open thereto. 4. An intake manifold ?tting comprising the combination with a block having faces adapted to be clamped between manifold ?anges and a central aperture registerable with manifold open ings, and a channel in one of said faces adapted to be closed by one of said ?anges when the ?t ting is assembled in the manifold, and a plurality of ducts opening from said channel to said aper ture at various points about the periphery there of, said block being provided with a valve seat for each such duct between said channel and said aperture; of a supply pipe leading through said block to the channel; and valve means individ ually adjustable in said block to and from the respective seats, whereby to control relative de livery from said pipe to said aperture individually through each of the several ducts. 5. An intake manifold ?tting comprising a CI block having a central aperture constituting a manifold section and a plurality of ducts opening through said block tangentially to said aperture at points spaced about the periphery thereof; in combination with supply means communicat ing with the several ducts, said block being pro vided at each duct with a valve seat between said supply means and said aperture; and needle valves associated with each of the several ducts and individually adjustable to and from the re 15 spective seats to control relative delivery indi vidually through the several ducts at the points of said aperture to which said ducts open.
