MANIFOLD-COVER.

Specification of Letters Patent.

Patented Sept. 6, 19 21.

Application filed December 80, 1918. Serial No. 268,808.

' and Ireland, residing at Regina, Province of Saskatchewan, Dominion of Canada, have invented certain Improvements in' Manifold- Covers, of which the following is a specification.

This invention relates to improvements in u internal combustion engines and particularl to providing means to heat the intake manifold, and consists in an adjustable cover for the manifolds of automobile engines.

its object is to provide a casing by means of which the heat of the exhaust manifold may be transmitted to the intake manifold, without interfering with the flow of gases through. either manifold.

1 am aware that numerous'forms of manifolds cast in one piece are known and used. By means of this invention it is not necessary to replace the manifolds provided with the engine, as this cover produces the result in cheaper and more convenient form when adjusted to such manifolds.

it is especially adapted to the well known Ford engine but can be equally well adapted to any engine in which the two manifolds are on the same side of the engine.

The heating of the intake manifold is well known as a means of improving the quality of mixture of gas and air which is fed to the cylinders of the engine, and also ameans of preventing condensation in the intake manifold.

Reference is made to the following drawings in which Figure 1. shows the inside half of the inner cover with the position, of the manifolds drawn in dotted line.

Fig. 2. shows the cover in position.

Fig. 3. is a vertical section on the line 33 of Fig. 2.

Fig. l. is a horizontal section on the line H of Fig. 2.

The construction of this invention is briefly, a close fitting casing of thin metallic sheeting in contact with the outer portions of the manifolds and over this a. cover of non-conducting material. The spaces between the manifolds within the casing may be filled with conducting material 81 in loose form such as iron filings.

In order to make the inner cover readily adjustable, I have divided it into two portions of which the edges overlap when in posltion.

The outer cover is preferably in one piece, when practicable.

In the form shown in the annexed draw- I ings, 1 represents the face of the cylinder casting to which the manifolds are attached, with the studs 4 and ll projecting therefrom. K

lhe inside half 7 of the inner cover is shown in Fig. 1. This is perforated with holes through which the studs t and ll and the junction ends of the

manifolds

2 and 3 pass. Washers 10 of suitable size are placed over the studs 4 to hold the cover portion 7 in close contact with the

manifolds

2 and 3 when adjusted. The outer half 8 is perforated, with holes for the studs l and 4.1. Both halves are cut away to provide for the intake pipe 31 and the outlet pipe 21. The ends of the stirrups 5 press the outer half 8 of the inner cover down on the

manifolds

2 and 8.

The outer cover 9 preferably consists of an insulated casing 91 of asbestos or similar con-conducting material and an outer casing 92 of sheet metal or other protective material.

T he edge of the cover 9 is adapted to fit neatly on the surface 1 as shown in Figs. 3 and 4-. lhe cover 9 may be secured to the manifolds by the two end studs l1 b the nuts 61 which hold the stirrups 51 as s own in Fig. 4:. All the stirrups are thereby inclosed within the cover 9. Other means of securing the outer cover in position may be adopted in applying my invention.

By means of this improvement the heat from the exhaust manifold is transmitted to the intake manifold and the mixture passing into the cylinders is prevented from condensing on the walls of the manifold and is heated before compression. By means of the ready adjustability the invention may be rapidly installed or removed if conditions require such alteration.

What I claim is 1. The combination, with an exhaust manifold and an intake manifold, of a cover therefor comprising an inner casing and an outer casing each consisting of a cup shaped metallic sheet portion, stirrups resting on the outer casing, stirrup pins passing through the stirrups and the inner and outer casin and securing the casings to the manifol s,

heat 'gconducting material between the two casings, and an outer removable insulating portion having means for securing the same to the manifold. I

2. The combination with an exhaust manifold and an intake manifold, of a cover therefor comprising an inner casing and an outer casing each consisting of a cup-shaped metallic sheet portion, stirrups resting on the outer casing, stirrup pins passing through the stirrup's and the inner and outer casings and securing the casings to the manifolds and an outer removable insulating portion having means for securing the same to the manifold.

3. The combination with an exhaust manifold and an intake manifold, of a cover therefor comprising an inner casingand. an

outer casing each consisting of a cup-shaped metallic sheet portion, stirrups resting on the outer casing, stirrup pins passing through the stirrups, the outer and inner casings and washers resting on the cylinder casting, and securing the casings to the manifolds.

In testimon whereof I aflix m signature.
