A lever 29 having at one of its end portions an elongated slot 33 with which a stud 3| upon the manipulating rod 24 is conveniently pivotaliy associated, has its end spaced from said rod fixed, as at 32, upon a shaft 33 rigidly carrying an armature 34 of a magnet 35 in a housing 36 of ordinary or preferred structure. A coil spring 31 upon saidshaft 33 has one of its ends made fast to the shaft, as at", and its other end secured to a part of the housing, as at 39. See Fig. 7. The coil spring 31 acts in 'the same direction as the coil spring 26, to normally hold the lever 23 swung to its farthest rearward position.

Numeral 43 represents a throttle actuating rod slldabie in brackets 4| upon the engine, and 42 denotes a coil spring upon said rod, between a bracket 4| and a collar 43, normally holding said throttle actuating rod in its retarded position (the location which would ordinarily place the throttle of the carburetor in idling position) An equalizing bar 44 pivoted at one end, as at 45, to the throttle actuating rod, is provided at its other end with an elongated slot 46 conveniently pivotally associated with a stud 41 upon the manipulating rod 24. The equalizing bar is also provided at about its mid-length with an elongated slot 43 conveniently pivotally associated with a stud 49 upon a lever 56 fixed to the shaft 5| of the throttle valve l6, said shaft 5| being mounted in the walls of the intake manifold. See Figs. 1, 2 and '3. 34 is a collar upon the throttle actuating rod 43 adapted to engage a'bracket 4| to limit rearward movement of said throttle actuating rod.

It is the service of the coil springs 26 and 31 to hold the manipulating bar 24 toward the left in Fig. 2 of the drawings to keep the fuel supply control valve l1 in 'the open position of the fuel supply line l4, and also to keep the equalizing bar 44 situated toward the left to locate the lever 53 in the idling (nearly closed) position of the throttle l6, provided the throttle actuating rod is in retarded position as -in said Fig. 2.

Itis the service of the magnet, when energized to a suflicient extent, to actupon the armature 34 to rotate the shaft 33 and swing the lever to advance the manipulating rod 24 to the closed position. of the valve l1, and also to swing the lower portion (see Fig. 3) of the equalizing bar 44 forwardly to position the throttle approximately wide open, against the action of the coil springs 26 and 31 whereby to provide for a free flow of air to the engine cylindersto the exclusion of explosive mixture. But one of these coil springs 26 and 31 is required, although both may be employed to advantage.

The magnet 35 can be energized only when the throttle actuating rod is retarded, and said magnet is adapted to have sufficient power to actuate the armature 34 against the action of the coil springs 26 and 31, or against either of said coil springs when one is employed, only when a throttled down engine is being driven by a force other than explosions in its cylinders, as when a vehicle is driving a throttled down engine, or a throttled down engine is racing.

Referring more particularly to Fig. 8, I have there disclosed a wiring system to be utilized in connection with the improvement. In said figure, 52 is a generator, 53 is a lead wire from said generator to a contact 54, 55 is a lead wire from said contact 54 to the magnet 35, 56 is a wire connecting the poles of said magnet, 51 is a' lead wire from the magnet to a second contact 53, the contacts 54 and 53 together comprising the fixed contacts of a switch 53 in said housing 36,

and 63 is a lead wire from said second contact 53 to the ammeter 6|. Clearly, with the contacts 54 and 53 unconnected, a current will fiow through the magnet, viathe leads described, from generator to ammeter, to energize the magnet, but by electrically connecting the fixed contacts 54 and 53, thecircuit will be shunted, and the magnet will lose its energy.

Referring to Figs. 1 to 7, the switch 53 consists of the fixed contacts 54 and 53 spaced apart a distance to allow a pivoted contact 62 to wipe between said fixed contacts. Said fixed contacts are suitably supported upon the housing, or the engine, in any convenient manner to be insulatedfrom each other and from said housing, or engine, the contact 53 desirably being a rectangular bar, andthe contact 54 being a rectangular bar having an extension or spring arm 63 arranged parallel to the contact 53 and providing the desired resiliency for the fixed contact members of the switch 55. The pivoted contact 62 is a lever or arm fixed, as at 64, upon a shaft 65 mounted in the housing 36 about the shaft 33. Numeral 66 represents a lever having one of its ends fixed upon said shaft 65, as at 61, and its other end provided with an elongated slot 63 conveniently pivotally receiving a stud 63 upon the throttle actuating rod 40. The pivoted contact 62 is properly-insulated from the shaft 65 in any convenient manner. As disclosed, said shaft 65 is of insulating material.

It will be clear that the magnet 35 will be in the circuit having the generator and the ammeter at all times when the throttle actuating rod is retarded as in Figs. 2 and 3 to cause the pivoted contact 62 to be out of engagement with the fixed contacts 54 and 53 and the switch 53 tothus be open, and that when the throttle actuating rod is so retarded, the fuel supply inlet will be closed and the throttle valve will be wide open provided the magnet isenergized to an extent sufllcient to overcome the action of the coil springv 26, or the and predetermined condition. For example, the

magnet can be stronger than the coil springs so long as the engine speed. is at or above a predetermined speed, and said coil springs can act 'when the engine speed is below said predetermined speed. This certain speed would ordinarily be that speed just above the speed at which the engine would normally operate with throttle actuating rod retarded, so that when this speed of engine is reached and said throttle actuating rod is retarded, as when a vehicle is driving the engine, or the engine is racing, the fuel line is closed and the throttle valve is wide open, but at all othertimes the fuel line is open'and the is connected with the shunt the circuit away from the 55 .to the pieces 86. A coil spring 88 fixed to ,i engine as at B9 and to an extension of the equal- 70 closed and the air the ignition circuit is designated 10. It includes throttle valve is positioned asin an ordinary engine now of commerce. Or the magnet can overcome the coil springs when the vehicle" speed has reached a certain speed. Or the magnet can overcome the coil springs at all times when there is connection between an However, it is preferable that the magnet be reengine and vehicle.

lated to the engine speed, because when the engine speed is the factor utilized, all of the circumstances of engine use when it is desired to feed air to cylinders instead of gas mixture can be met, as has hereinbefore been fully set forth.

It has already been stated that the throttle valve is held in idling (almost closed) position 5 by. the equalizing-bar 44 when the coil springs 26 and 31 are holding the manipulating rod 24 in rearward position and the throttle actuating rod is retarded. As the throttle actuating rod is advanced, the upperportion of the equalizing bar g0 44 is swung forwardly, as in Fig. 1, to open said throttle valve a distance corresponding to the amount to which said-throttle actuating rod is advanced. Upon the initial movement forwardly of said throttle actuating rod the current is as'shunted from the magnet to insure that the coil springs will stably hold the lower end of the equalizing bar rearwardly, so that during all conditions of partially advanced or totally advanced throttle actuating rod, the throttle It will function in precisely the manner as is now usual with ordinary explosive engines of co erce.

In view of the fact that the pivoted contact 62 throttle actuating rod to be brought intopositiveengagement with the fixed contacts 54 and 58 as said throttle actuating rod is advanced, the circuit 'isshunted away from the magnet and the fuel'inlet opens and the throttle adjusting devices sive mixture at the commencement of the ad'- vancement of said throttle actuating rod.

It may be desirable that when the throttle actuating rod is advanced from retarded posi- 45 tion, the pivoted contact 62 be brought into en:

gagement with the fixed contacts 54 and 58 to magnet before the equalizing bar 44 is manipulated, to thus insure a feed of gaseous fuel at the commencement 0 of opening of the, throttle valve. In Fig. 3 we have disclosed a modified construction for this purpose. As disclosed in said Fig. 3. the throttle actuating rod is in two spaced apart pieces, denoted 85 and 86, arranged in a sleeve 81 fixed the izing bar 44 as at 90, holds the piece 86 in rearward position, while a collar 84' limits the rearward movement of said piece". The coil spring so 42 holds the pieces! in rearward position, while a collarfll limits rearward movement of said piece 85. Clearly initial advancement of 'the piece 85 will cause the pivoted contact 62 teengage the fixed contacts 54 and 58, and further 65 advancement will cause the piece 85 to engage the piece 88 to advance the equalizing bar.

It is preferable that open at all times when onithe dash of an automotive vehicle, to a third contact 12 in the housing 36 adjacent and spaced 75 from the contact 58, and also includes said conarmature- 34 in nipulating bar become inoperative simultaneously with the advancement of said 40 throttle actuating rod to insure a feed of exploclosed and throttle valve open,

the fuel supply line is tact 58: and the lead on to the ammeter u. As

clearly disclosed in Figs. 1 to I, the contacts 12 and B8 combine, in about the manner as already described in connection with the contacts 54 and B8, to provide fixed contacts of a switch 18 which includes a pivoted contact 14 fixed upon the shaft 33 and attached to" the armature 34, as at Iii, to move over said contacts with said armature and wipe 12 and 58. The pivoted contact 14 is insulated from the shaft 23 and the any convenient way. Apin. 18 in the shaft it enters insulation 11 about said shaft, and a pin 18 fixes said pivoted contact 14 to said insulation. At 19 is an insulating bushirig having tight fit in a cavity at of the armature 34, numeral ll representing a screw passing through the pivoted. contact 14 and entering said insulating bushing. See Fig. 7. The third contact 12 is suitably supported upon the housing, or the engine, in any convenient manner to be insulated from the contact 58 and from said housing, or engine. Said contact 12 is a rectangur lar bar having an extension or spring arm 82 arranged parallel to the contact 58, opposite the contact 54, and providing the desired resiliency for the fixed contact members of the switch I! when wiped by the pivoted contact 14.

The arrangement is such that when the coil springs 26 and 81, or one of said springs when a single spring is employed, are holding the ma- 24 and the lever 29 in their rearward positions to situate the fuel supply control valve in open position and the throttle valve adjusting devices in inoperative position, the armature 34 is so located that the pivoted contact I4, fixed to said armature to move therewith, is

- that theignition circuit will be made at all times when explosive mixture is being fed to the cylinders, and will be broken at all times when air free of explosive mixture is entering said cylinders. I

It may be found desirable at times when the throttle actuating rod is retarded and the engine is being propelled by avehicle, or is racing, to open the fuel supply line and render the throttle valve adjusting devices inoperative, as, for example, when it is desiredto utilize the vacuum or suction in an intake manifold to do work.

such as actuate a booster brake, or operate a wind shield cleaner. This can be done by closing a switch, which would be the equivalent of the switch 59, to shunt the circuit away from the magnet. The switch could be closed automatically, as when a booster brake was to be actuated.

or could be closed manually, as when a wind shield cleaner actuated by vacuum or suctiodin .the intake manifold was to be set into action.

It will be evident that the air admitted through the air inlet l5 of the carburetor, with fuel line can be transmitted to the cylinders at approximately atmospheric pressure.

It will also be evident that the keeping of gasoline out of the cylinders when a, vehicle is pro pelling an engine or the engine is racing and there is no need for utilizing gasoline to accomplish propulsion, saves gasoline, and, in addition td-thi thefurnishing of air approximately at atmospheric pressure to the cylinders under the light load working conditions which exist therein when the engine is propelled'by'a vehicle or is racing, provides pressure in the cylinders preventing the drawing of lubricating oil into the combustion chambers.

While we have preferred to disclose the magnet 35 as the-special device to actuate the fuel control valve and the throttle valve, it is to be understood that other devices could be substituted.
