INTAKE HEATER FOR GASOLINE ENGINES.
Patented Feb. 7, 1922.
Application filed December 4, 1919. Serial No. 342,435.
T aZZ c0 ham it may concern Be itknown that I ELnRrcn V. MoCUL Loon, a citizen of the United States, re-
' siding at Hutchinson, in the county of Reno,
State of Kansas, have invented certain new and useful Improvements in Intake Heaters for Gasoline Engines; and I dohereby 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 new and useful improvements in heating devices and particularly to devices for heating gas charges before entering the engine cylinders, whereby engines of the explosive type can be easily and quickly started in very cold weather.
One object of the present invention is to provide a novel and improved heating device which is disposed in the leg of the intake manifold of the engine and by means of which the gases will be preheated before entering the cylinders with the result that rapid vaporization will take place and the proper and easy ignition of the gases will be accomplished.
Another object is to provide a novel and improved device of this character wherein the changes in the structure of the engines now in use is obviated, the device being arranged to be easily and quickly applied at the point of connection between the carburetor and'the intake manifold.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is an elevation of a portion of an explosive engine showing the position of the invention.
Figure 2 is an enlarged vertical sectional view taken on the line 22 of Figure 1, through the connection between the carburetor and the manifold.
Figure 3 is an enlarged horizontal sectional view taken on the line 3-3 of Figure 1, between the layers of insulation of the connection between the carburetor and the manifold.
Referring particularly to the accompanying drawing, 10 represents a portion of an engine having the intake manifold which includes the vertical leg 12, the manifold being shown at 11. This leg is formed with a peripheral flange 13 around its lower end which is arranged to register with a. similar flange 1 1. of the carburetor 15 for the reception ofthe clamping bolts 16. Between these flanges 13 and 1 1 are disposed two layers of insulating material 17, secured together with shellac or other suitable adhesive material. An opening 18 is formed centrally through the insulation of a diameter slightly greater than the interior diameter of the leg 12, and in the wall of the opening there is disposed the circular loop of the flat ribbon wire 20. The ends 21 and 22 of this wire are passed outwardly between the layers of insulation, as shown in the sectional views, the end 21 being secured to a binding post 23, which is grounded on the vertical leg of the intake manifold, while the other end 22 is connected to a binding post 24 carried by the arm 24: which is formed integrally with the lower layer of'insulation or which may be a separate element attached thereto in any suitable manner. nected a wire 25 which leads to one side of the battery 27, and has a switch A therein, while the other side of the battery is grounded at 26. This circuit is shown diagrammatically in Figure 3.
It will be noted that there are disposed between the layers of insulation short wires 19 the inner ends of which are looped around the heating loop of the wire 20, to support the said loop in proper position within the opening for radiating its heat into the manifold, with the result that the gases which pass through the manifold will be highly heated before entering the cylinders of the engine.
It will thus be understood that when the switch is operated to close the circuit, the current will flow through the ribbon wire and cause the same to become heated, and to radiate its heat into manifold leg so that the gases will not pass into the cylinders in a cool condition. This is highly useful in very cold weather where the cylinders and manifold have become cold.
In applying the invention to engines now in use, it is only necessary to remove the gasket in the manifold leg and substitute the one of the present device, or if the gasket in the leg is of insulating material, two layers are used and the wire placed between them in the manner hereinbefore described What is claimed is: 1. In a preheater for the explosive charge On the post 24 is con- V o r 1,406,048
of a gas engine the combination with the leg of the intake manifold and the connec-' tion to the carburetor, of a multi-layer of insulation disposed between said leg and carburetor connection, having a central opening of greater diameter than the inte rior diameter of the manifold leg and con-' nection with the carburetor, and an electric heating wire loop supported wholly within the opening of the insulation between the .leg and carburetor connection and having its ends clamped between and their extremi- 1 I ties beyond, the insulation layers.
2. In a gas preheater for explosive engines, a pair of layers of insulationadapted V for disposition :in the connection between the inanifoldiand carburetor of the engine,
the insulation having a central opening of greater diameter than the interior of the the said layers and connected respectively to a binding terminal and a ground, and 25 supports clamped between the layers and projecting into the said opening and secured V to the wire ring.
