CARBURETER CONTROL.

Specification of Letters Eatent.

Patented Dec. 3, 19181.

Application filed December 27, 1916. Serial No. 139,221.

To all whom it may concern:

Be it known that I, DAVID L. WINTERS, a

citizen of the United States, residing at Annapolis, in the county of Anne Arundel and State of Maryland, have invented certain new and useful Improvements in Carbunecessity of throttling the charge, and the loss of power and fuel resulting therefrom.

A further object of this invention is to provide means for controllinga carbiiretcr so operable as to enable the vehicle driver to determine the most eilicient mixture for the engine under varying load conditions and varying conditions of temperature, altitude. humidity. and the like. A still further object of this invention is the provision of a carburetor with means operable from the drivers seat, whereby the volume of the charge may be increased or diminished at. will by means of an auxiliary air inletcooperating with the carburetor control.

lVith the foregoing and other objects in View, as will from time to time hereinafter appear, this invention consists in the pcouliar construction and combination of the various cooperating elements of a carburetor control as set forth in the following specification and more particularly pointed out in the appended claims. In the operation of an int rnal combustion engine it is necessary that the most efficient mixture of fuel be immediately available at certain times. due to changes in load or atmospheric conditions. In the effort to overcome these variances ofoperation it is common practice to adjust the carburetor by hand while the vehicle is standing still in order to produce what is believed to be the most efiicient mixture for the engine. Under these conditions however the most of ficient adjustment cannot be obtained, as such adjustment to be as near perfect as pos sible must be made while the vehicle is in motion and the engine is operating unde' normal or abnormal load conditions. l-Vith the view to remedying this defect I have in vented the mechanism hereinafter described.

'teferring to the accompanying drawings forming a portion of this specification and illustrating the preferred embodiment of the invention, as well as a modification thereof, and wherein the same reference characters indicate the same parts wherever used,

Figure 1 is a side elevation of a portion of an automobile, partly hut away, to show the device as applied to a carburetor;

Fig. 2 is a detail side elevation partly in section and partly broken away, showing a modification of my invention, and

Fig. 3 is a detail perspective of the operating lovers.

4- dcsignates. a carburetor of any suitable type provided with the usual air inlet and the usual gasolene supply needle valve 5, controlled by a stem 6 having a knurled cap 7 at the upper end thereof to ordinarily permit of manual adjustment, the fuel supply to the engine being controlled by a throttle valve 8 carried by a shaft 9 to which is attached a lever 10 provided with a ball joint 11 adapted to receive a rod 12 which in turn is provided with a second ball joint 13 adapted to engage the socket upon a curved extension 14:, of a rod 15 extending upwardly along the steering column 16 to a point below the steering wheel, where the rod 15 is provided with a collar 17 and an operating handle 18, the lower portion of the rod 15 having a collar 19 thereon adjacent the extension 14.

In the construction shown in Fig. 1, the stem 6, of the needle valve 7 is encircled by means. of a collar 20 held in place thereon by a lock nut 21 and carrying an arm which is connected to a rod 23 carrying a joint 24. adapted to engage an arm secured to a cylindrical shaft 26 which incloses the member 15 and extends upwardly along the steering columnilfi to a position below the steering wheel, where said memher 26' is provided with a handle 27 and a slot 28 flanked by lip-standing cars 29. 30 through which is passed a bolt 31 provided with a wing nut 31' the purpose of which will hereinafter be explained. The upper portion of the member 26 bears against the collar 1? urried by the shaft 15 and the lower portion of the member 26 abuts 7 member 26 nlml as des ribed against the collar 19 adjacent the extension 14 of the member 15.

The collar 17 has depending therefrom 9. lug 32 bearing against the upper end of the member 28 and the member 28 has a similar upstanding lug 33, bearing against the lower face of the collar 17, the construction being such that a limited rotary movement of each member independently of each other is pern'ntred until the lugs come in contact when the two members will move together as hereinafter explained.

In the modification shown in Fig. 2, which is more particularly adapted for carburetors in which the feed of gasolene from the gasolene supply is normal at all times, the crank extension 25 of the cylindrical carries, by means of the member 24 a rod 34 carrying a ball 35 adapted to engage the socket 36 of a shaft 37 of an auxiliary air valve 38 placed in the manifold 39 at any suitable point. The construction of the throttle valve and its controlling mechanism in the modification is the same as that described in Fig. 1.

The operation of the device is as follows:

In the construction illustrated in Fig. 1 the operating levers 18 and 27 are normally clamped together by means of the wing nut 31 suiliciently tight to insure joint movement thereof upon the movement of either one of the same, but not however sufliciently tight to prevent the independent movement or shit'tin; of lever 27' to effect a readjustment of the mixture of air and gasolene, during whichre-adjustment the lever 18 is preferably held by the thumb, oFby the rack on the steering column, as may be found most convenient, this movementbeing lim-,

itcd by the lugs 3233 to prevent the operator using too rich or too lean a mixture, as the case lfnder some .working conditions, especially those due to change of altitude, temperature, humidity, or the like, it has been found desirable in internal combustion cn ginioperation to permit the inllow of addilionnl air through the inlet manifold. In order to provide for this the construction illustrated in Fig. 2 is placed in the same position on the steering column [6. [n this construction the carbureter is provided with -nn-ans lol'rpcrnllltlng a continuous flow of ga olcne o equal volume at all times, the only adjustment being, that of the air from and to the carburetor and the manifold. in this construction the throttle valve 9 is o erabove and the auxiliary air valve Il-S operated by means of the bandle 27 through Ibo medium of the members 2.7. Ill and 57 to secure the proper amount of additional air passing into the manifold -l l. ulu-n upon proper response from the/engine s-rhouin; that the correct mixture is bring obtained and the most ellicicnt mixmay be. for effective combustion.

'with a pair of inlets, of a di-m-ndcnt controlling means ture used with relation to the speed of the machine, the operating members 26 and 15 remaining clamped together sufiiciently tigg t to permit of simultaneous operation y means of either of the levers 18-27.

As shown in Fig. 2, the auxiliary air valve is preferably capable of a. limited movement during which it remains closed, thus said valve may be operated in either its opened or closed position by shifting its operating lever.

It will be seen that by the construction above described independent operation of the air throttle, and fuel control of the carbureter may be effected in the preferred form, and that simultaneous operation of both may be elfected when the proper and most economical mixture has been ascertained, and that by the modification shown a proper and independent adjustment of the throttle valve of the carburetor and the auxiliary air valve of the manifold may be made, the operating chambers thereof remaining fastened together by the medium of the mechanism described, whereupon a simultaneous operation of the two valves may be effected in order to continue the supply of the proper charge. v

I realize that considerable variation is possible in the details of construction and arrangement of parts without departing from the spirit of my invention, and I therefore do not limit myself to the specific form shown and described. As an instance of this, any well known means may be employed to effect, upon the operation of leyer 27. a more extended movement of the fuel valve stem 7.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I
