INVENTOR ATTORNEY Patented June 29, I937 UNITED STATES PATENT OFFICE mm FOR cAnBUaE'roas Milton E. Chandler, Detroit, Mich. Application February '28, 1935, Serial No. 8,642
4 Claims, wuss-14o).
The object of this invention is to reduce the amount of heat flowing back into a carburetor through the flange. 5 The second object is to enable the lower half 5 of a die cast carburetor to be made of a die casting instead of being made of gray iron as it is now constructed. I
The third object is to eliminate the heat conducted through the bolts which connect the carburetor to the inlet-manifold flange; -'The fourth object is to provide heat radiatingv means closely associated with the,heat insulating gaskets. The problem is made more dimcult for the reason that heat is. brought up as close to the inlet manifold flange to which the carburetor is bolted as it is customary to direct th mixture directly into the hot spot at the point where the carburetor is bolted to the inlet. A
I propose to use'anovel means of holding the carburetor to the intake manifold. At the present time the flanges are of large area and mass 1 and a great deal of heat is transmitted from the intake manifold into the barrel of the carburetor and thence intothe float bdwl causing the gasoline to boil. With the present flanges it is not possible to make themof die cast material because they tend to warp owing to strain being placed a long way in fromthe center. I
not be ,in contact with the carburetor flange,
40 very little heat will be transmitted from manifold to carburetor barrel: In extreme cases it will be desirable to use and hold in place by the narrow flange, a gasket that resiststhe conduction of heat between the manifold andthe barrel of the carburetor. It might also be desirable to L either mould in this gasket or clamp in place heaifradiating flns. In other words, I propose inthis design to have .a means ofattaching a carburetor to the manifold so thatthe flange itself, together with the'gaskets, adds very ma terially in radiating heat between the manifold and the carburetor, rather than conducting heat ,-from the manifold to the carburetor. This will 5 very materially reduce the difflculti'es had with' L shaped stampings.
ing it, S is the flange of the and D are the two studs (moun transmit the minimum possible-amount of heat and that the studs 0 and D are exposed as are gasoline boiling and percolating into the intake manifold.
The preferred form of stamping to clamp the carburetor to the manifold will be two simple The horizontal leg per- 5 forated for the stud and extending over to rest on the lug of the carburetor. The vertical leg will extend down andthave a projection that will extend into a hole bored in the intake manifold which will serve as sort of a dowel hole to locate 10 the position of the L shaped stamping. The part of the stampingprojecting into the dowel hole will be smaller than the remainder of the leg so that the leg will rest on the face of the manifold flange: The lug on the carburetor will have 15 locating points in contact with the L shaped 'stamping to prevent the carburetor from turning. Likewise with these L shaped clamps\therecan be used the .thick gaskets and radiating fins between the intake manifold and the carburetor 2o flange if desired.
Figure 1 shows a carburetor bolted to an inlet I manifold having an exhaust jacket around the inlet manifold.
Figure 5 shows in elevation a view taken on plane 55 of Figure 2 In the figures A is the mixture entrance to the inlet manifold, B is the exhaust-jacket surround-' t manifold, C v in the flange S) which bolt the lower half E of acarburetor F to the flange S of the mixture entrance A of the inlet manifold. G l, G2 and G3 are three gaskets ,i.n erposed between the lower half E and the air entrance A of the carburetor. Two L shaped stampings H and J engage with a shoulder K on the end of the lower half Eof the carburetor F. Radiating discs L and M are used as spacers between the gaskets GI and G2 and between the gaskets G2 and G3. In order to. keep the radiating discs L and M in place dowel pins'N and 0 are provided. It will be noticed that the stampings H and J will the radiating L and Mto the air which is blown over-top 0K manifold from air cooling fan in the car. f
' In Figure 3 ears? are shown punched out of the spacers L andM and engage with openings in the gaskets GI, G2 and 3. Y
' In Figures 4 and 5 the L shaped clamp H is ,,shown with a projection Q which engages with a hole R drilled into the flange S of the exhaust heated inlet manifold entrance A-B.
What I claim is: 1. Means for clamping a carburetor to the exhaust heated-inlet manifold of an intemal combustion engine comprising a plurality of studs projecting from said manifold, a flange on the end of the-carburetor, L shaped clamps engaging with the flange, with said manifold and with said studs, a plurality of heat insulating gaskets between said flange and said manifold, heat radiating means interposed between said gaskets for the purpose described.
flange and said manifold, heat radiating means associated with said gasket for the purpose de- I ,scribed.
3. Clamping means for connecting a carburetor to a heated inlet manifold of an internal combustion engine comprising a relatively narrow flange on the end of the carburetor, a plurality of L shaped clamps engaging with said flange and with said inlet manifold, studs projecting from said inlet manifold, said studs being adapted to lock said clamps to said flange and to said inlet manifold.
4. Clamping means for connecting a carburetor to a heated inlet manifold of an internal combustion engine comprising a relatively narrow flange on the end of the carburetor, a flange on the entrance to the inlet manifold, studs projecting therefrom, a plurality of L shaped clamps, means for locating the clamps on said flange, means associated with the studs for locking the clamps to the carburetor and to the flange of the inlet manifold.
