Application filed .1 anuary t, 1917. [Serial No. M1332.
To all whom it may concern:
Be it known that T, FREDERICK U. BALL, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in a Dashboard Controlling Mechanism for Carbureters, of which the following is a specification.
This invention relates to dash-board controlling mechanisnis for carburetors and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.
It is usual in automobiles to have a mechanism'mounted on the dash-board by means of which the qualityof the mixture supplied by the carburetermay be controlled. Such control is necessary to adjust the carbure'ter for ordinary running but more particularly is necessary with relation to differences in temperature in the fuel being used and also differences in temperature in the engine, as for instance, in starting. The usual controlling mechanism consists of a push and pull button with a yielding detent for holding the button in difierent adjustments. The difficulty with such a device is that the movement is nearly in the line of vision so that accuracy of adjustment is diflicult and further the amount of movement that can be conveniently accomplished is slight so that a nice graduation of the movement cannot be conveniently accomplished.- The object of the present invention is to provide a mechanism which may be substituted for the ordinary ush and pull buttonand obviate the diflicu ties incident to the use of such a button. 7
The invention is illustrated in the accompanying drawings as follows Figure 1 shows an outline of a carburetor. Fig. 2a section on the line 22 in Fig. 3. Fig 3a section on the line 3-3 in Fig. 2. Fig. 4 a face view of the dial and operating button.
Fig. 5 a rear view of the control actuating device.
Fig. 6 a development of the cam formmg a part of said device. j
1 marks the carburetor, 2 the intake of the carbureter, 3 a choke valve in the intake, 4:" a rock lever for actuating the choke valve and 5 the dash. This is provided with an opening 5. This may be the-usual opening used with the push and'pull button.
The mounting 6 has a plate 7 which bridges and closes the opening 5. Extending inwardly from the plate is a bearing post 8 with an extension 9. A lever lO'is pivotally mounted on the extension 9 by means ofa pirr 11. A spring 12 extends from a lug 13 on the lever to a projection 14: on the extension 9 and tends to hold the lever in a forward position. The rod A'is secured to the end of the lever 10, the rod 4 extending to the carburetor and having a forward and back movement in actuating the choke valve.
A cam 15 is mounted on a shaft 16. It is locked with the shaft by a pin 17. The cam 15 has a cam face 18 whichoperates against the end 19 of the lever 10.
The cam face 18 is developed in Fig. 6. Through a large portion of the throw of the cam the pitch is very slight so that a very nice adjustment of the position of the choke valve 3 may be made through the action of the cam. This slight pitch is indicated in the initial throw of the cam at. 18 in Fig. 6. In starting the cold motor it is desirable to operate the choke valve to a much greater extent than would be desirable for ordinary running. To get thisv greater movement of the valve the pitch of the cam is increased during the latter part of its throw as at 18 (Fig. 6'). A stop 18' is provided in the end of the cam. This stop engaging the end 19 limits the movement.
The shaft 16 extends through the bearing post 8 and a knurled operating button 20 is secured to the shaft by means of a pin 21. A finger 22 extends from the button 20 and travels over a dial 23 formed on the face of the plate 7. The dial has the diflerent graduations marked upon it.
In operation the button 20 is grasped and turned. This rotates the cam 15 which in turn-swings the lever 10 andthis actuates the choke valve 3 through the linkage hereinbefore described. As the button 20 is turned the pointer or finger 22 is carried over the dial and inasmuch as this direction of travel is crosswise of the mounting and crosswise of the dash it is readily visible to the operator so that a nice adjustment may .be had and this adjustment may be repeated without dificulty. Furthermoretoo the travel of the cam as indicated by the pointer being practically a complete turnof thebutton is much greater than would be t it ordinarily practical with a push and pull button so that a nice adjustment may be readily accomplished. The pitch of the cam is so slight that the frictional engagement of the cam with the lever will lock at any point of adjustment without a positive looking device.
The carrier is so formed that it can be readily inserted through the opening in the dash which is bridged by the plate 7, this being preferably such that the mounting may be readily substituted for the push and pull button without alteration of the dash if desired. It is difficult to get at the dash from the front side and, therefore, by forming the mounting such that it may be attached to the face of the dash as by the screws 7 a it may be conveniently attached.
What I claim as new is 1. In a dash-board controlling mechanism for carbureters, the combination of a dashboard mounting; a carbureter control actuating means having a forward and back movement; and devices carried by the mounting and actuating said means, said devices having a movement in a direction crosswise of the mounting and in the same general plane as the dash With the mounting in place, whereby the movement of the devices is across the line of vision of an operator and converting this movement to give the forward and back movement of the means.
2. In a dash-board controlling mechanism for carburetors, the combination of a dash-board mounting; a carbureter control actuating means having a forward and back movement; and devices carried by the mounting, said devices having a rotative movement on an axis extending from front to rear of said mounting, whereby the movement of said devices is across the line of vision of an operatorand this movement is converted to give the forward and back movement to the means.
3. In a dash-board controlling mechanism forcarbureters, the combination with a' carbureter control actuating means; a dash-board mounting; and devices carried by the mounting and actuating said means,
said devices having their operative movement in a direction crosswise of the mounting, and said devices comprising mechanism for varying the controlling action of the means with a given movement of the device in different parts of the movement of the device.
4. In a dash-board controlling mechanism for carbureters, the combination with a carbureter control actuating means; a dashboard mounting; and a cam carried by the mounting and actuating said means, said cam having a cam face of varying pitch.
5. In a dash-board controllin mechanism for cal'bureters, the combinatlon with a carbureter control actuating means; a dashboard mounting having a shaft extending lengthwise therethrough; a cam on said shaft; a lever actuated by the cam said lever actuating said means; a spring or returning the lever; an operative button for operating the shaft; a dial; and a pointer on the button operating over the dial.
6. In a dash-board controlling mechanism for carbureters, the combination of a carbureter control actuating means; a dashboard mounting adapted to bridge an opening in a dash-board; and devices carried by the mounting and actuating said means, said devices having their operative movement in, a direction crosswise of the mounting and being adapted to operate through the dash-board opening bridged by the mounting.
7. Ina dash-board controllin 'mechanism for carbureters, the combination with a carbureter control actuating means; a dashboard mounting comprising a dial adapted to bridge an opening in a dash-board; and devices carried by the mounting and actuating said means, said devices rotating on an axis lengthwise of the mounting and comprising means for indicating the movement of the devices over the dial, said devices beingadapted to operate through the dashboard opening bridged by the mounting.
In testimony whereof I have hereunto set my hand.
FREDERICK 0. BALL.
