J. DYKSTRA Er AL THROTTLE HOOK-UP Filed Oct. 17, 1931 2 Sheets-Sheet 1 Patented June 1, 1937 UNITED STATES PAl E THROTTLE HOOK-UP Ware Application October 17, 1931, Serial No. 569,368
7 Claims.
This invention relates to internal combustion engines and has particular reference to the combination or interrelation of the self-starting mechanism with the throttle operating means to facilitate starting.
The object of the invention is to interrelate the mechanism to operate the throttle of the carburetor with the starter so that when the starter is operated to start the engine, the throttle will be cracked wide open or any desired opening and on the release of the starting pedal, the throttle will return toward closed position but Will remain open suiiiciently wide to cause the engine easily to idle, or to give the engine a relatively iast idle.
The structure by which the object of the invention is accomplished consists of mounting on a rod or shaft secured to the engine block, three levers, one of which is connected by means of a rod to the starting device, a second by means of a rod to the accelerator pedal, and a third by means of a suitable linkage to the hand operated lever usually positioned on the steering wheel. A connection leads from the three levers to the throttle of the carburetor to operate the same. This latter connection is interrelated with the three levers so that it is operated each time any one of the three is operated.
On the drawings:
Figure 1 is a side View of a portion of the engine of an automotive vehicle with parts broken away to illustrate the invention.
Figure 2 is a view taken substantially on the line 2-2 of Figure 1 with the en-gine shown in full lines.
Figure 3 is a perspective expanded view of the three levers of the invention.
Referring to the drawings, the numeral 2 indicates the vehicle as a Whole having the dashboard 4, the iioor 6, and the inclined toe board 8. The usual chassis frame is indicated at IB while |2 indicates the engine. The engine has interrelated therewith the usual intake and exhaust manifolds I4, the carburetor |'6,.the air cleaner intake muffler |8, the throttle valve 20, the fuel heater 22. Inside the vehicle, there is positioned the accelerator pedal 24 pivoted as at 26 at its rear end to the inclined portion 8 and at its forward end there is pivoted thereto at 28 the rod 30. The usual starter pedal is shown at 32 secured to a shaft 34 journalled in ears 36 secured to the flywheel housing. The shaft 34 has the angularly bent portion 38 to the end of which there is pivoted as at 40 a link 42, pivoted at 44 to an arm 46 pivoted at 48 to the (Cl. 12S-179) motor housing. The arm 46 has the hook end 56 which, when the starter pedal 32 is operated, strikes the button or switch 52 to close the circuit to the motor 54 to start the engine through the usual gearing on the flywheel (not shown). The steering column is indicated at 56, the' steering wheel at 58 and the hand throttle lever at 66, the latter preferably being mounted on the steering wheel. The steering column is preferably mounted by means of the brackets 62 to the chassis frame I by means of bolts 64. The parts so far described are conventional and per se form no part of the invention.
A shaft 66 is permanently mounted in the engine block as shown at 68 in Figure 2. On the shaft 6'6, there are journalled the accelerator lever l0, the hand throttle lever l2 and the starter lever |4. The three levers are best shown in the, perspective view in Figure 3. The rod 3|) from the accelerator pedal 24 is secured at its other end at the opening 'I6 in the arm 'I8 of the lever I6 and is suitably secured therein by means of a cotter key or otherwise. The opening is for the reception of the shaft 66 While an arm 82, substantially at right angles to the arm 'I8, has an opening 84 in its end in which there is received the hooked end 86 of a link 88 connected at 90 to a bell crank lever 92 pivoted at 94 to a bracket 96 secured to the engine block I2 by means of the bolt 98. The other arm |66 of the bell crank lever has an opening for the reception of a hooked end |02 of a rod |64, the other end of which is hooked as at |06 into an opening in a lever IUS secured to a shaft ||0 on which the throttle 20 is secured.
Referring again to Figure 3, it will be noted that the lower end of lever 'I0 has the flat lug |I2 and the angularly extending lug H4, the purpose of which will be later described.
The hand throttle lever 'I2 has the opening ||6 for the reception oi the shaft 66. An arm I I8 has the opening |20 in its end in which there is received the socket of a ball head |22 swiveled to the end of a rod |24. The other end of the rod |24 is hooked into an opening in a crankarm |26 secured to a tube |28 extending through the steering column 56 and up to the hand wheel 58 and it has a hand lever '66 mounted at its other end. The lever l2 has the downwardly and outwardly extending lug |30 which engages with the lug ||2 on the lever 10. The lever 12 has the extending arm |32 having a screwthreaded opening |34 in which there is received the adjusting screw |36 secured in adjusted position the hand operated throttle 60.
' throw or return the by means of the lock nut |38. The purpose of this screw will be later decribed.
The starter lever 'I4 has the opening |40 at its upper end in which there is hooked the end of a rod |42, the opposite end of which is hooked into the portion 38 of the shaft 34 as indicated at |44. 'I'he lower portion of the lever 'I4 is U- shaped as indicated at |45 and both legs of the U have the openings |48 for the reception of the shaft 66. The bearing portion of the lever 12, indicated at |50, is received in the U portion |40 between the openings |48. The U-shaped portion |46, therefore, extends considerably below the shaft 66. The lever T4 has the lug or ear |52 extending away therefrom, the purpose of which is to strike against the end of the screw |36. Referring to Figures 2 and 3, the lug ||4 of the lever '|0` fits against or is adapted to be moved by the lower end of the U-shaped portion |46.
The operation of the structure is as follows: Assuming that the engine is not running and cold and it is desired to start, the operator presses the starter pedal 32 which will cause the hook 50 to press the button at 52 to start the motor 54 which in turn will turn over the engine. The movement of the lever 32 will simultaneously move the rod |42 which will swing the lever 'I4 on the shaft 66 and cause the U-shapecl portion |46 to strike the lug ||4 which will swing the lever I0 to cause the linkage 88, 92, |04 to operate the throttle to wide open position. The lug or ear |52 on the lever '|4 at a given time, depending upon the adjustment of the screw |36,
' will strike the end of the screw to operate the lever 12 which in turn will operate the hand lever 60 by means of the linkage |24, |26 and column |28. 'Ihe operation of the starting pedal 32 to start the engine will, therefore, simultaneously operate the accelerator pedal 24 and When the starter pedal 32 is released, the coil spring |54, secured at one end |56 in the engine block and having its other end |58 hooked about the lever T0, will parts toward the position shown in Figure 1. The starter pedal 32 will be thrown to its normal or retracted position while the accelerator pedal 24 will be moved rearwardly until the lug l2 of the lever 70 strikes against the lug |30 of the lever l2. When these two lugs meet, the throttle operating mechanism will be stopped from further movement for the reason that the spring |54 is of insumcient strength to move the han-d throttle 60 and its interrelated linkage. Owing to the fact that the ear |52 has moved the lever 12 a given distance and as the spring is unable to return the mechanism to this given distance, the throttle will be returned only from wide open position to the position in which it is held by the lever 12. This position is suiicient to permit normal idling of the engine. If the operator wishes to return the throttle to fully closed position, it will be necessary manually toI operate the lever 60 to move the link 'I2 to its initial position.
By aconsideration of Figure 3, it is to be noted that if the operator desires to use the accelerator pedal to operate the throttle, this can be done without interfering with the starting pedal for the reason that the lever 'I4 will not be operated when the accelerator pedal 24 moves the link 30 to operate the. lever 10. When the lever I0V is operated the throttle will Abe operated in the usual way from the link 88 but, as the lug |4 will move away from the U-shaped portion |46 and the lug 2 will recede from the lug |30, the accelerator pedal may be operated to operate the throttle independent of the other linkage.
In operating the throttle by the hand lever 60, the lug 30 on the link 72 will strike against the lug ||2 and the lever 'l to swing the lever 'I0 on the shaft 66 which in turn operates the throttle linkage. The hand throttle 68 will allow the lever 'l2 to be moved a suiicient distance to open the throttle to its full position before the lug |30 strikes the U-shaped portion |48 of the starter lever 14 so that the hand lever may be operated without interfering with the starting mechanism.
