CARIBURETOR-PRIMING-ROD MOUNTING.

Application filed May 15,

Michigan, have invented new and useful Improvements in Carburetor-Prinning-Bod Mountings, of which the following 1s a specification.

The object of my invention is to provide new and useful automobile instrument board carburetor controlling means, of simple, durable and inexpensive construction.

A further object of my invention is to proride means whereby the volume of air to be rarburetted in an internal combustion engine carburetor can be simply and easily controlled by the driver of an automobile from his seat. I

A further object of my invention is to provide means whereby the volume of air admitted to the carburetor of an internal com bastion engine to be carburetted may be adjusted by the operator of the engine to meet the varying atmospheric conditions under which such an engine is operated, and for maintaining such adjustment as long may be desired by the operator.

.A further object of my invention is to pro vide means whereby a mixture of air and a. volatile inflammable liquid, such as gasoline, containing a high percentage of the volatile inflammableliquid, as compared with air, may be-readily obtained from a carburetor without the necessity of varying the amount of volatile inllanunable liquid supplied to the mixing chamber of the carburetor.

\Vith these and other objects in view my invention consists in the arrangement, combination, and construction of the various parts of my improved device, as described in the specification, claimed in my claims, and shown in the accompanying drawing, in which:

Figure 1 is a vertical sectional view of an automobile instrument board and dash board with my improved device mounted thereon.

tional binding washers used in my improved device.

In the following description of the parts and the principle of operation of my improved device, corresponding parts of my device shown in various figures of the draw ing are always referred to under the same reference numeral.

In Figure 1 the instrument board, cowl and dash board of an automobile are indicated generally by the reference numerals 10, 11 and 12, respectively. The controlling rod 15, Figures 1 and 2, passes through the bearingslel and 16 in the instrument and dash boards, and 12, respectively, and is connected with the upper arm 18 of the bell crank lever 18-18. For convenience in operation the end of the controlling rod is provided with a knurled head 13. The frame 19-19, see Figures 1, 2 and 3, of my improved bracket is detachably fastened to the dash board 12 by the small bolts 17- 17. That portion of the frame indicated by the reference numeral 19 has cars at each end thereof through which the bolts l'i' pass. The side flanges 19 of the frame are properly drilledto permit passage of the bolt 20 therethrough, said bolt 20 formingthe shaft upon which the bell crank lever 18-13 turns. The bell crank lever 18-18 Figures 1 and 2, is disposed between and contacts with the frictional binding washers 21, Figures 2 and (1. These frictional binding "washers 21 maybe of any suitable mi-iterial, and are held in position against the bell crank lever 1818 by the tension of the spring 22, see Figure 2, which tension may be varied by means of the nut 23 on the bolt 20, the adjustment of the nut being maintained by the lock nut 24. The frictional binding washers/21 are preferably formed with a square end, see Figure 4., whicn rests against the frame 19 and prevents the washers from turning with the hell crank. lever 18-48.

The actuating rod .25, Figures 1 and 2, extends from the hell vant: lever 18 tot-he lever 2-6 of the carburetor 33, said lever 26 being fined to the shaft 28, the end of which shown, Figure l, and the air inlet valve witl'iin the air inlet passage 2? of therei curator is mounted upon this shaft 238. This air inlet valve is it well kno n feature; i

' herewith,

normally held against etc 29 by the tensionrarburetor construction and is not shown The air inlet valve lever 26 oi the spring in WlllCl position theair inlet valve of the carburetoris set for ordinary operation of the engine, An auxiliary operating rod 31 is pivotedfto the lever 26 and eirtendsto the front of the automible,

, whereby the carburetor air inlet valve may be manipulated from that point.

in the practical operation of my improved device it will he understood that it is for the purpose of providing means for adJusting the position o't the air inlet valveof a car huretor n, an internal combustion engine and thereby the proportion of gas and air in the explosive mixture formed within the carburetor, and for maintaining such adjustnient of the air inlet valve aslong as may he desired; such adjustment being made without up necessity of the operator leaving his seat inthe automobile. This is partieu l'arly important when operating an automo bile equipped with mechanical means tor starting, the engine, in, other words, a self sterter. l

it is necessary to provide means for vary lug; the proportions of gas and air in the ex: plosive mixture delivered by the carburetor for several reasons, the most important of which is toprovide a rich lmixture, i. e. one containing a high proportion of gas to air, for start-ingthei engine, as such a mix ture ignites more readily than av lean one,

or one containing a greater proportion of buretor by means of adjusting the position the needle point in the inlet valve to the carburetor mixing chamber, through which valve the volatile inflammable liquid passes, in "order to vary the size of the valve openiugand thereby the amount of volatile inflammable liquid admitted to the mixing chamber through the valve. On account of v the fact, however, that a very minuiechange inthe amount. oi volatile inflammable liquid admitted to the mixing chamber will seriously affect the operation of the engine, and the further fact that it requires considerable time, and 'more skill than the average driver of an automobile possesses, to readjust the needle valve to the proper position for ordinary running} it hasheen i'ound impracticable to attempt to vary the proportion er gas and air in the ezgp-losive mixture cleaver by these means. Furthermore, frequent ma" nipulation of the needle point tends to roughen the line end thereof and thereby make impossible the proper adjustment of this valve.

911 the other hand the adjustment of the air inlet valve of the carburetor is a simple one and this valve can be quickly reset toa predetermined properrunnmg position with absolute certainty; Therefore, by means of my improved device the operator of an automobile equipped with same can vary at will the proportion of air in the explosive mixture formed in the carburetor ,mixing chamber to provide a rich or a ,lean

mixture, and he can, if desired, maintain any particular proportion indefinitely.

The operation of mv'improved device in the form herein .descri is as follows:

The actuatin .rod 25, Figures-1 and 2, being connected y means of the bell crank lever 18---18 to thelever 25, which in turn is connected to the lever 26, it will be seen that movement of the bell crank lever arm 18 in an upward direction will tend to ull up the lever ,26, and thereby tend to c ose the air inlet valve in the air inlet assage 17 of the carburetor 33, and thus diminish the volume of air entering the carburetor,

The bell crank arm 18 being formed inte g'ral with the arm 18, it willbc seen that all that is necessary for the operator to do in order to manipulate the air inlet valve of the carburetor is to pull out the controlling rod 15, which in turn moves the bell crank lever arms 18 and 18 and thereby the acturating rod 25, thus adjusting the position of the air inlet valve. The frictional binding washers 2]., being compressed by thetension of the spring 22 tend to hold the hell crank lever 153-48 in any position in which it may be setby movement of the controlling rod l have only shown two of these frictional binding washers 21, but it will be understood that more could be used if desired Without departing from the spirit of my invention.

, When it is desired to re-open the air inlet valve the controlling rod '15 is pushed in or toward the bell crank lever 18-182 which depresses the bell crank lever arm 18 and the tension of the spring 30 upon the lever 26 returns it to its normal position against the stop 29. I prefer tomake the actuating.

rod 25 slightly smaller in diameter than the hole at 32 in the bell crank lever arm 18 in order to secure a loose or slip fit, as this perinits operating of the lever 26 by means of the auxiliary control rod 31 from the front of the engine without changing the position of thebell crank lever 18-18.

it will he understood that I do not desire to limit myself in this application to the use of my ithprovekl device on automobiles,

but that it may also be used with appropriate mounting on tractors, motor boats. motorcycles and other machines in which it is desirable to provide simile and inexpensive means for controlling the air inlet 'alve of a carburetor. Changes may be made in the arrangement of the parts, as for instance the bracket 19 might be mounted on some other part of the machine, as for instance theradiator or frame.

Some changes may be made in the arrangement and construction of the various parts of my improved device without fleparting from the spirit of the invention therein and it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof.
