tain new and useful Improvements in Manifold Coversyand I do hereby declare the following to be a full clear, and exact de scription of the invention, such as will en- 10 able others skilled in the art to which it appertains to make and use the same. i

This invention relates to new and useful improvements in engine attachments and more particularly to an attachment adapted to be applied to that type of engine used in automobiles, aeroplanes and the like, the main object of the present invention being the provision of a device adapted to be applied to the exhaust pipe and to partially enclose the exhaust pipe and extend over the intake manifold whereby to conduct the heat from the, exhaust pipe to the intake manifold whereby the fuel mixture passing into the engine cylinders through the intake 2 manifold will be thoroughly heated and the liquid particles vaporizedbefore reaching the cylinders.

Another object of this invention is the provision of a device which can be quickly and readily applied to an engine without the necessity of additional bolts or other fastening means, the device being retained in position by means of the bolts utilized to retain the well known form of pipe clamps in position.

A further object of the present invention is the provision of a casing adapted to be arranged over a portion of the exhaust manifold and to enclose the intake manifold and having formed upon its interior a plurality of longitudinally and transversely extending ribs whereby the heat from theexhaust manifold will be readily conveyed downwardly to the intake manifold to thoroughly heat the fuel passing through the manifold so that when the fuel reaches the engine cylinders it will be thoroughly vaporized. A

With the above and other objects in View the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings in which Figure 1 is aside elevation of an auto- 1921. Serial No. 481,868.

mobile engine illustrating" my improved .device applied thereto Fig. 2 is a longitudinal sectional'view' of my attachment, and.

"Fig. '3 is an interior perspective view.

Incarrying out my, invention Iprovide an elongated body member l'formed of metal and provided with 'OiitStandingcup shaped members 2 which are adapted to i I receive the usual pipe clamps used in securing the intake andexhaust pipes, said clamps being retained in position by means of the bolts 3 and these bolts are utilized 1n securing my improved device in position as each of the cup-shaped members 2 are provided with suitable openings 4 to receive the bolts 3, the regular securing nuts being used to clampthe device in position.

The body member 1 is provided at one end with an outstanding flange 5 which extends along one side of the body to a point adjacent the center thereof toflthus form a cup-shaped enclosure at the forward end of the body. The opposite end of the body is provided with spaced flanges 6 arranged uponcopposite sides of a recess 7, said recess being adapted to receive one end of the pipe clamp which is not enclosed in the body of the attachment. i

Upon the interior of the body and formed upon opposite sides of the center or in other words upon opposite sides of the cup-shaped members 2, are the spaced flanges 8 provided at intervals with suitable recesses 9 arranged in transverse alignment whereby to receive the intake and exhaust pipes. The

From theabove it will be noted-that 1 if have-provided a simple and durable device which can be readily cast into a single piece so as to reduce the manufacture of the device to a minimum, making the same simple veyed through the channel members to the in its construction so that it can be placed upon the market and sold at a very low cost.

In applying the device, the nuts are removed from the bolts 3, thedevice arranged in position as shown in Fig. 1, the ends oi the bolts 3 projecting through the openings 4 in the members 2, the nuts then replaced upon the bolts 3 and screwed down against the outer surfaces of the members 2. It Will= readily heated and vaporized before reaching the engine cylinders as the heat from.

the exhaust manifold Willbe readily conintake manifold. I claim: 5 j

In a device of the class described, a body member having cup-shaped recesses formed therein and provided with perforations at the bottom'ofthe recesses, spaced flanges arranged upon opposite'sides of the center of the body, sa d flanges belng provided with transverse recesses, a plurality of transverse flanges arranged upon opposite sldesol the first flanges and a cup-shaped member ii'o'rm ed at one end of the body and,

and"

projecting parallel with the flanges as for the purpose set forth. In testimony whereof I afli my signature.
