Another object of the invention is to provide novel means whereby the mechanism hereinbe- -fore referred to may be rendered operative or ,inoperative by manipulation of the ignition switch.
Another object of the invention is to so construct the device that the circuit closer for the circuit of the starting motor will remain open, when the accelerator pedal or fuel feed is operated to increase the motor fuel supply, the circuit closer being permitted to close when the operator takes his foot off the accelerator pedal, or otherwise cuts off the fuel supply.
In the accompanying drawings:
Figure 1 shows in side elevation, a device constructed in accordance with the invention, mounted on a portion of an automobile; 4
, Figure 2 is a front elevation;
Figure 3 is a top plan;
Figure 4 is a vertical section taken through -the device per se;
Figure`5 is a section on the line 5-5 Vof Fig. 4; Figure 6 is a section on the line S--B of Fig. 4; Figure 7 isa section on the line --l of Fig. 6.
In Fig. 1, the numeral I designates the vdash board of an automobile, the foot board appearing at 2. The steering column is shown vat 3, and the accelerator pedal at 4, the pedal 4 being `retracted by a compression spring 5. The accelerator pedal 4 is pivoted to a bell crank lever 6,
fulcrumed intermediate its ends as shown at l. The ignition switch is diagrammatically indicated by the numeral 8, and includes a handle 9. Movement of the handle `S upwardly closes the circuit through the ignition switch. Although the ignition switch 8 is shown as being mounted on the steering column 3, it might be located elsewhere, without departing from the spirit of the invention.
The bell crank lever G, see Fig. 3, is connected to operate the throttle valve 54 of the carbureter V53, said carbureter having its outlet leading to the intake manifold 56.
A box-like support I0 is secured Yto the for- Award side -of the dash board 1I. The support .I0
carries the upper Abinding post Il 'and the lower post I2, located on opposite sides of the support, as Fig. 4 will show, the binding posts, of course, being properly insulated. The binding` post I2, connected to a starting motor 5I, see Fig. 3, carries an upstanding switch terminal I4, located within the support IB. The switchterminal I4 isY adapted to cooperate with a vertically movable switch tongue I5 pivotallymounted on the binding post Il as indicated at 4S. See Fig. 4. A battery 52 connects onto the binding post II as indicated in Fig. 3.
A cylinder l5 is secured to the top of the support It! and has a connection il, leading to the intake manifold of the Vengine '59, the construction being such, in any event, that piston suction is transmittedto the top of the cylinder IB. A lpiston rod I8 reciprocates in a-gland I9 on the lower end of the cylinder I5, and extends downwardly into the support I0. Pistons 2i) and 2| are secured to the piston rod IB and slide in the cylinder I6. The cylinder I6 has a vent 5I.
An adjusting nut 22 is threaded on the piston rod-I8, within the support I. A compression spring 23 surrounds the piston rod I8. The upper end Vof the spring 23 abuts against the gland I9, and
the lower end of the spring abuts against the adjusting nut 22. The piston rod I8 carries a lateral armp24, see Fig. 7, said arm being held for adjustment on the piston rod by superposed nuts 25. The arm 24Vcarries a piece of insulation 26 which contacts with the lower surface of switch tongue I5.
A slide 2l is mounted for horizontal reciprocation in a guide 28 carried by the support I0.
The slide 2l has a notch 29 derning a cam 30. v
The cam 3i! cooperates with the insulation 26 on the arm 24 of the piston rod I8, vto raise the `piston rod I8, and, also, to raise the switch tongue I5 out of engagement with the switch terminal I4. A link 3| is pivoted to the slide 2l and to an arm 32 that is connected to the handle Y9 of the ignition switch 8.
-Referring to'Figs. 4 and 6, it can be seen that a horizontally movable lever 33 is fulcrumed intermediate its ends atv34 on the casing I. One end of the lever 33 extends into the casing, and the other end of the lever extends out of the casing. On the inner end of the lever 33 there isan upwardly extended, curved iinger 35 adapted to engage under the switch tongue I5. I.'Ihe inner end of the lever 33 Vslides in a slotted stud 36 carried by the casing I'El. A compression spring 3l surrounds the stud 35, one end of the compression Vspring engaging the inner end of the lever, and the opposite end of the spring bearing against the casing I0.
The outer end of the lever 33 cooperates with the upper end of a second lever 38, located on the side of the casing IB, and fulcrumed intermediate its ends, as shown at 3B, in Fig. 1, on the dash board i, or elsewhere. One end of a link 43 is pivoted to the lower end of the lever 38, and the opposite end of the link 43 is pivoted to the lever 6. As previously mentioned the accelerator pedal 4 is also pivoted onto the lever 6 and pressure downwardly upon the pedal 4 causes movementl of the upper end of the lever 33 towards the dash thus causing the curved linger 35 of the lever 313 to move to a position underneath the switch tongue I5 to prevent movement thereof to a contacting and operating position.
When the engine is running, and when there is sumcient piston suction in the connection Il' and in the upper end of thecylinder I6, the pistons 25 and 2I raise the piston rod I8, and the arm 24 on the piston rod rides under and swings up the switch arm I5, out of contact with the switch terminal I4, see Fig. 4 and the circuit of the starting motor 5I, through the binding posts II and I2, is open. The sp-ring 3l swings the lever 33 on its fulcrum 34 until the finger 35 of the lever 33 is underneath the switch tongue I5,
as shown in Fig. 4. When the engine stops, and
piston suction fails in the connection I'I and in the upper end of the cylinder I5, the piston rod I8 begins to move downwardly, but it cannot move downwardly to close the switch tongue I5 on the switch terminal I4, because the finger 35 V of the lever 33 supports the switch tongue I5. When the operator takes his loot oi the accelerator pedal 4, the spring 5, shown in Fig. 1, moves the parts in the direction of the arrows in Figs. 1 and 6. The upper end of the lever 38 of Fig. 1, engaging the outer end of the lever 330i Fig. 6, moves the lever 33 to the position of Fig. 6 and withdraws the finger 35 of the lever 33 from beneath the switch tongue I5. The switch tongue Y I5 then is carried downwardly, by the action of the spring 23, and closes upon the terminal I4, thereby completing the circuit through the startingmotor, and putting the engine into operation.
'When the engine starts the intake manifold vacuum in the connection I'I and in the cylinder I6 raises the piston rod I8 to the position of Fig. 4 or thereabout. When the operator Yputs his foot on the accelerator pedal and pushes it in a direction opposite to that indicated by the arrow A in Fig. 1, the upper end of the lever 38 is moved away from the outer end of the lever 33, and the lever 33 can now respond to the spring 3l, the finger 35 of the lever 33 being restored to a position underneath the switch tongue I5, as shown .Fig 4. The operator can push forward'on the accelerator pedal 4, and increase the fuel supply to the motor, at any time, without withdrawing lthe finger 35 of the lever 33 from beneath the switch tongue I5 and causing the switch mechavnism I5-I4 to close the circuit of the starting moton It is only by the backward or release movevment of the accelerator pedal 4 that the finger asanio 35 of the lever 33 is withdrawn from beneath the switch tongue I5, as is shown in Fig. 6.
When the operator disconnects the ignition switch 8 by the operation of the handle 6 downwardly, the link 3I moves the slide 2'! to the left, see Figs. l and 5, and the cam 30 moves the piston rod I 8 and the switch tongue I 5 upwardly, in the way hereinbefore described. When the operator closes or connects the ignition switch 8 by raising the handle 9, the link 3| carries the slide 2'I to the right, into the position of Fig. 5, so that the switch arm I5 is above the notch 29 1n the slide 2l, and then the operations hereinbefore described can take place.
