EDWIN L. WALKER, OF DENVER, COLORADO.
AIR-HEATER.
Specification of Letters Patent.
Patented Aug. 20, 1918.
Application filed April 25, 1917. Serial No. 164,448.
To all whom it may concern:
Be it known that I, EDWIN L. WALKER, a citizen of the United States, residing at Denver. in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Air-Heaters; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to devices for heating the air before admitting it to the carbureter of an internal combustion engine such as used on motor cars; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a front view of an air heater constructed according to this invention. Fig. 2 is a plan View of the same. Fig. 3 is a cross-section through the heater, taken on the line 33 in Fig. 1.
A trough-shaped plate 2 is provided. and is preferably formed of thin sheet metal. and has flanges 3 and 4 at its top and bottom edges respectively. The plate 2 is tapered to conform to the shape of the exhaust manifold 5 of the engine, which is shown in dotted lines. The flanges 3 and 4 are arranged to overlap the manifold, and they may be pressed into contact with it. but as an airtight contact is not essential, joints do not have to be formed between these parts.
The lower flange 4 has notches 6 cut in it so that it will fit over the branches of the manifold which are connected to the engine cylinders, and a lug 7 projects from the flange 4 and is secured by one of the bars 8 which hold the manifold in place. The position of the plate 2 is adjusted so that a narrow air space is formed between the plate and the manifold, and this air space communicates freely with the atmosphere at the ends of the plate.
A circular nozzle 9 is formed on the middle part of the plate 2, and 10 is an air pipe one end portion of which is mounted pivotally on the nozzle 9, and which is also slidable on it so that the main portion of the pipe may be adjusted laterally of the plate 2.
A quarter bend 12 is formed on the upper end portion of the pipe, and the lower end portion of the pipe is curved around in a plane parallel to the plate 2 and is provided with a nozzle 15 for connecting it to the air inlet of the carburetor. The engine and its carburetor are of any approved construction, and the air pipe 10 is moved pivotally on the nozzle 9 to place the lower nozzle 15 in engagement with the carbureter.
The air is drawn through the narrow pas: sage between the exhaust manifold and the plate 2, and is heated by contact with the exhaust manifold, and the hot air then passes down the pipe 10 to the carbureter.
This device can be readily applied to any approved form of internal combustion engine such as used on motor cars, and the pre-heating of the air before admitting it to the carburetor effects an economy in the use of the hydrocarbon fuel.
What I claim is:
1. In an air heating device, a troughshaped member adapted to fit over an exhaust manifold and form therewith a heating space for air. said member having a laterally projecting outlet nozzle for hot air, and an adjustable air pipe having a bent portion at its upper end which is pivoted on and slidably connected with the said nozzle. said pipe having also a bent portion at its lower end which projects in a plane substantially parallel to the said member.
2. In an air heating device, a relatively long trough-shaped member comprising a flat plate tapered to conform to the shape of an exhaust manifold and provided with flexible projecting flanges adapted to overlap and fit against the top and bottom of the manifold, thereby forming a heating space for air, an outlet nozzle for hot air secured to the said plate. and an adjustable air pipe having a bent portion at its upper end which is pivoted on and slidably connected with the said nozzle, said pipe having also a bent portion at its lower end which projects in a plane substantially parallel to the said plate.
In testimony whereof I have affixed my signature.
EDWIN L. WALKER.
