AUTOMATIC ACCELERATOR.

Application filed July 29,

This invention relates .to a device to be used for automatically accelerating the supply of gasolene to the carbureter of an automobile engine without the use of the cus- 6 tomary foot accelerator pedal, and it has reference to a device which comes automati- .cally into play while changing the gears.

A device of this class is particularly advantageous when driving in heavy trafic and 1 in places where extra precaution is essential.

It furnishes an even smooth acceleration,

permitting the driver to keep one foot on the clutch and the other one on the brake insures smooth operation in either forward or backward motion and practically eliminates objectionable noise caused by racing of the motor, such as is now the case with the present accelerator arrangement.

The device is clearly advantageous in that it overcomes injurious depreciation of parts caused by racing motors particularly. when changing from high to low onsteep grades. It thereby effects a noticeable saving in fuel.

The particular details and their relative arrangement and association will become morereadily apparent from the following description and drawings In the drawings V Figure 1 is a view in section and elevation z: 1 of one embodiment of the invention showing the complete structure. I

the clutch, said control coming into play and shifting the gears and operating the clutch in a customary manner.

Attention is first invited to Figures 1 and 2 wherein it will be seen that the reference character 6 designates generally the shank of a clutch pedal extending through the openmg in a floorboard 7. This shank carries a special clamp 8 with which a push rod 9 is connected at one end. The push rod is connected at its opposite end with an upstand ing portion 10 on a swingably mounted U- shaped carrier 11. Incidentally, this carrier is located within a suitably shaped housing 12 and the arms thereof are connected with an adjustable pivot forming shaft 13. As shown, the carrier constitutes a mounting for va'spring-pressed latch 14. The latch is cooperable with a shoulder 15 formed on a se mental plate 16carried by a tubular shaft 1 The tubular shaft extends transversely across the housing 12 and is fastened by set screws or equivalent means to a rock shaft 18. On the left hand end of the rock shaft in Figure 2 is a crank arm 19 which serves a purpose to be hereinafter described. On the opposite end is a short arm 20 with which a return 1 spring 21 is connected.

, Attention is here invited to a gauge element 22 having a stop lug 23 on its inner pivoted end for cooperation with a complemental lug 24 on the tubular shaft 17. These lugs cooperate in limiting the rotation of the shaft 17 in one direction. This element 22 is formed with aupointer 25 cooperating with a scale 26 in order to indicate accurately the adjustment of the stop lugs; A retaining nut 26 is provided for this element, thereby permitting it to be held in any suitable ad-' justed position. r Attention is now invited to a bracket 27 which is rigidly fastened to the floor board. On the end portion of this bracket is a pivotally mounted bellcrank 28 carrying an anti- .friction roller 29 for cooperation with a cam 30 on an adjustable abutment or bracket 31 carried by the fuel control rod 32 leading tetheearbureter 1 1101; shewu).- Connected 10o to the bellcrank through the medium of a short link 33 is an actuator 33% of the design indicated. This is also pivotally mounted on the bracket 27 and the one arm thereof is connected with a rod 35 which is in turn connected with the aforesaid crank arm 19. It is yet to be stated that suitable attaching brackets 36 are connected with the aforesaid housing 12, whereby to permit the latter to be mounted on the motor or chassis as desired.

\Vith this arrangement it is obvious that when the clutch pedal is pushed down to release the clutch, the pushrod 9 is moved in a direction from right to left as indicated by the arrow. This swings the U-shaped member 11 upon its pivot in a corresponding direction, thus bringing the latch 1l- 1n the position to drop behind the shoulder 15 on the segmental plate 16. Now, when the foot is removed from the clutch pedal to allow the clutch toibe thrown in, the latch being engaged in the shoulder 15, serves to rock the shaft 17 as well as the shaft 18. This produces an actuation of the abutment 31 and carbureter control 32 through the medium of the shankarm 19, part 35, 3a, and the bellcrank 28. At a predetermined time in this return of the clutch, the latch 14 clears the shoulder 15 owing to the eccentricity of the pivot 13 as compared to the axis of rotation of the shaft 17.

Referring now to Figures 8 to 5 inclusive, it will be seen that the reference character 37 represents a carbureter having a suitable actuator '38. Cooperating with this part 38 is abracket 39 carrying an anti-friction roller 40. The bracket is mounted on a slide 41 which is movable through a bore in a guide bloc 42. A push rod 13 is connected with its slide at one end, and at its opposite end is connected with a crank arm 44. The crank arm, as shown in Figure 1, is fastened upon the extendmgend of a small rock shaft 4-5 which is journaled for oscillation in a gear casing 46. A suitable attaching bracket is provided for this casing. Keyed or otherwise fixedly mounted on the rock shaft 45 is a bevelled gear l7 which cooperates with a bevelled pinion d8. The pinion 41-8 is car ried by airoscillatory shaft 49 which, as

shown in Figure 3 extends atiright angles to the push rod 4-3 and is coupled as at 50 witha short rock shaft 51 in an appropriate enclosure 52. The rockshaft 51 is provided witha rocker arm to which a push and pull link 54: is connected. This linkin turn is connected with the clutch pedal represented generally at 55. 1

IViththis arrangement it is obvious that when the clutch pedal is-operated, the link 54; serves to actuate the rocker arm This in'turn oscillates the shaft 49 which, through the medium of the intermeshing gearing 4:7 and 48, operates the push rod 43. Thus, the
