Canada Application April 1, 1932. Serial No. 602,547

4 Claims. (01. 123-122) The present invention relates to new and useful improvements in methods of internal com.- bustion motor control, and more particularly it pertains to such motors as are used. in connec- 5 tion with'motor vehicles. I

It is one of the objects of the present invention to provide means whereby air is introduced into the intake manifold of an internal combus- 1 tion motor at a point between the fuel supply tor inoperative.

It is a further object of the invention to provide a new and novel form of electric heater for heating the gas in its passage to the motor cylinders.

A further object of the invention resides in a novel control for the circuit of the heater and in which the heater is automatically energized and de-energized as the ignition circuit for the motor is energized and de-energized.

A still further object of the invention resides in a novel control for introducing air into the fuel supply line as above mentioned and in which the control is operated simultaneously with the ignition switch of the motor.

With the above and other objects in view, reference will be had to the accompanying drawings, wherein;

Figure 1 is a fragmentary view partly in eleva- 30 tion and partly in section showing a portion of an internal combustion motor, its intake manifold, and a portion of the instrument board of a motor vehicle,

Figure 2 is a longitudinal sectional view taken through the ignition switch of the ignition circuit,

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure 2,

Figure 4 is a detail perspective View of the cylinder of the ignition switch and lock,

Figure 5 is a longitudinal sectional view on an enlarged scale of a portion of the intakemanifold of the motor,

Figure 6 is a horizontal sectional View taken on the line 66 of Figure 5,

Figure 7 is a view in elevation taken at right angles to Figure 5, and;

Figure 8 is a detail perspective View of the valve which controls the introduction of air to the intake manifold of the motor. 7

Referring to the drawings by reference characters, 10 designates an internal combustion motor and 11 designates the intake manifold thereof, the intake manifold being supplied with fuel from a suitable carburetor or the like 12. The

and the cylinders of the motor to render the mo-. a section 18.

PATENT OFFICE referencecharacter 13 designates the dashboard V of a motor vehicle and 14 indicates the instrument board. Carried by the instrument board 14 there is a lock 15 preferably of the cylindrical type and said lock has a cylinder 16 movable of operation by means of a key 17 in a manner to be hereinafter described.

In carrying out the present invention, I provide, in the vertical leg of the intake manifold 11,

This section 18 has an extension 6 19 which extension is formed with 'an air passage 20 which leads from atmosphere to the interior of the manifoldjll. Mounted in this extension 19 there is a valve 21 and thisvalve. has a passage 22 which when in alinement with the passage 20Qestablishes communication. between the interior passage of the intake manifold 11 and atmosphere and when closed, this valve cuts off communication between the interior of the intake manifold 11 and atmosphere.

As best illustrated in Figure 5, an electric heating element 24 is carried by this section 18 and said heating element is preferably in the form of a coil. As best illustrated in Figure 1, the electric heating element is connected by 0 means of conductors 25 and 26 with the switch 15 and said switch isconnected by means of a conductor 2'7 with the ground 28, there being a suitable source of electric current supply herein illustrated as a storage battery. 35

By reference to Figures 2 and 3 it will be apparent that the cylinder 16 of the switch 15, is provided with a contact member 30 which is insulated from the cylinder by a suitable insulating material 31. Carried by the lock casing 15, there are two contact screws 32 and 33 and. the terminals of the conductors 26 and 2'7 are connected to the contact terminalthe conductor 2'? being connected to the contact terminal 32 and the conductor 26 being connected to the contact terminal 33. The conductor 25 which leads to the heating element 24 branches ofi from the conductor 26 at the point 35 and this conductor passes through the fuse or the like 36.

From the foregoing, it will be apparent as the key 17 is inserted in the lock cylinder 16 the cylinder may be rotated and the same turned until its contact member 30 bridges the contacts 32 and 33. This position of the lock cylinder 16 will complete a circuit between the battery 29 and the electric heating element 24 it being understood that said electric heating element is grounded as indicated at 37 in Figure 6. Thus as the ignition is turned on, current will be supplied to the heating element 24 and as the ignition that 1 I circuit is opened, the circuit to the heating element 24 will likewise be opened.

Means is provided for operating the valve 21 heretofore mentioned, and this means consists of a link or the like 49 connected to an arm 41 which in turn is carried by the lock cylinder 16 and to a second arm 42 carried by the valve 21. Thus it will be apparent that as the lock cylinder is turned through the medium of the arms 41 and 42, the valve 21 will be moved to opened and closed position the same being moved to its open position when the electric current is cut OE and to its closed position when the electric current is cut in. Stops such as 45 and 46 which are adapted to engage a pin 47 may be employed to determine the extent of throw of the lever 42.

From the foregoing it will be apparent that when the ignition is turned off, the valve 22 will be in its open position and any attempt to start the motor will only draw air in through the passage 20 in lieu of fuel from the carburetor 12 and the motor cannot under these conditions be started even though the ignition circuit be tampered with to an extent whereby the same would supply ignition to the cylinders.

V While the present invention has been herein illustrated in a preferred form, it is to be understood that the invention is not to be limited to the precise construction in which it is illustrated, but may be carried out in other forms without departing from the spirit thereof.

Having thus described the invention, what is claimed as new, and what it is desired to secure by Letters Patent of the United States, is:

1. In combination, a fuel supply manifold, having a passage leading direct to atmosphere, an electric heater in said manifold, a source of electric current supply for said heater, 2. control switch therein, a valve in said passage, and means for simultaneously operating said control switch and valve.

2. In combination, a fuel supply manifold having a passage leading direct to atmosphere, an electric heater in said manifold, a source of electric current supply for said heater, a control switch for the current supply of said heater, a valve for controlling said passage, means for operating said control switch, and means operated by said switch for operating said control valve.

3. In combination, a fuel supply manifold having a passage leading direct to atmosphere, an electric heater in said manifold, means for supplying electric current to said heater, a valve for opening and closing said passageway, a switch for controlling said electric current supply to said heater, and means whereby said valve is moved to open position when the switch is moved to open position and 'for moving said valve tolclosed position when the switch is moved to closed position.

4. In combination, a fuel supply manifold having a passage leading direct to atmosphere, an electric heater in said manifold, means for sup: plying electric current to said heater, a valve for opening and closing said passageway, a switch for controlling said electric current supply to said heater, and means whereby said valve is moved to open position when the switch is moved to open position and for moving said valve'to closed position when the switch is moved to closed position, said valve operating means being operated by said switch.
