THROTTLE IGNITION SWITCH INVENToR. @oaf/em 705mm, Jn
Filed 001;. 6. 1930 A T'ORNEY.
y Patented Oct. 4, `1932 PATENT {o1-FICE ROBERT EI. TBENER, JR., OFl KANSAS CITY, MISSOURI THEOTTLE IGNITION SWITCH y Application filed 'October 6, 1930. Serial No'. 486,702.
My invention relates to switches and more particularly to devices including switches in an ignition 'circuit for controllingan internal combustion motor, for example the motor operating a vehicle such as arboat, airplane or the-like, the principal objects of the invention being to enable the operator of the motor to suspend ignition promptly without requiring access to the motor,.and to provide means set by opening movement of a throttle lever, whereby an operator leaving the vehiclemay at the same time suspend .ignition and close Vthe throttle valve of themotor to reduce damage Lto the vehicle which might result Jfrom continued operation of the motor;
In accomplishing these and other objects of the invention, l have provided improved details ofrstructure, the preferred form of which is illustrated in the accompanying drawing, wherein:
Fig. 1 is a perspective view of my invention as applied to a motor boat shown moving through water, illustrating the device in ignition suspending andthrottle closing position, a boatman in the water near by, and a broken line whereby the lboatnian had conditioned the device for operation.
Fig. 2 is a side elevation of a casing member supporting the operating elements of the device and a throttle lever and throttle operating rod shown ragmentarily, the cover of the casing being removed.
Fig. 3 is a section on the line 3-3, Fig. 2.
Fig. 4 is a diagrammatic view of the wiring system of a motor driven vehicle having battery ignition system and equipped withV m invention. v Y
Referring in detail to the drawing: 1 designatesa motor boat 2 an internal 'combustion engine adapted to propel the boat, and having a throttlek valve'and spark plugs connected to an ignition circuit normally found in engines of this character. Y f
Mounted on one side wall of the boat adj acent the seat for the vboatman is a casing including mating body and cover members 3 and Ll comprising'plates or side walls having lower edge flanges 5, intermediate ribs or iianges 6, and upper edge flanges 7 forming aV relatively large chamber 8 and a cylindrical channel 9.
The Amembers are held together by bolts 1 0 with the flanges in close engagement to form the top vrand bottom walls of the casing, and an intermediate partition.
Pivotally mounted on a pin 11 in the casing adjacent the lower wall thereof, is a throttle lever 12 extending upwardly through slots 13 and'14 formed in the partition and topwall, and connected by a wire 15 with the carburetor control valve of the engine. Rearward pivotal movement of the lever may result in opening the throttle valve for admitting fuel and increasing the speed ofthe enine and forward movement of the lever will reduce speed and tend to Suspend operation of the engine.
Slidable inthe channel is an actuatoror plunger 16 adapted to'be forced in the directionv of the throttle lever by a spring 17 in the channel having onepend bearing against a plug 18 closing the rear end of the channel and an opposite end bearing against the rear end of the plunger.A
The plunger is notched to provide a stop shoulder 19 engageable by the upper end 20 of a plunger-locking switch bar 21 centrally pivotally mounted on a pin 22 set in the side walls of the casing, the tip extending through the slot in the partition to engage in the plunger notch, whereby the bar may lock the plunger in retracted position, and the plunger when released may move against the throttle lever and' rock the bar to suspend ignition as later described. The pin and switch are iu conductive relation to the casing.
rlhe slots further accommodate a cooking pin 23 mounted in the iront end of the plunger and extending downwardly into the chamber to engage the curved upper end of the switch bar, and whereby the plunger is retained in suitable position against rotation to present the notch therein downwardly and assure engagement of the nose of the switch bar with the stop wall of the plunger.
The switch bar is retained in plunger latching position by a releasing or latching lever 25 pivotal on a pin 26 mounted in the casing side walls and having a short front arm 27 provided with a squared tip engageable in a squared notch 28 formed in the lower end ot the switch bar. A spring 29 comprising a wire mounted on a stud 30 fixed to the casing has opposite ends engaging respectively the lower face of the longitudinal ribs 6 and the rearwardly extending longl arm of the latching lever wherebyV the short olfthe 1e,- ver is urged into bar'latching position.v
A wire or release cable 32 fastened' to the outer free end of the longer arm `ot the latching lever extends through a bushing 33 mounted inmatinggrooves inthe casing memberV and is provided with a ringy 34 towhich an t easily brealablestring 85 may be fixed. The I otherendot ythe string may be attached to the lwrist ot the boatman wherebyfa'slight pullon theY string will result in tippingy the latchingjlever and releasing the switch bar to 2Oy permit the spring-pressed plunger to move forward in the casing to shift the switch bar and operate the throttle lever.v Y v The device may be easily adaptedfor con-v trollingian ignition circuit inv either battery 25 ormagneto-operated systems and is preferably adapted to be applied for use selectively with either' ot said'systems. For use insystems including a single magneto, aV contact 37k mounted in oneot the cas@k JQ ing members, preferably thebody member as illustrated in Fig. 3, is connected to the. circuit, andthe switch'bar when shifted by the V plunger moves into conductive. relation therewithfor shorti-ng the ignition circuit through Y the casing members -3-4and the wire l5.V
" When two magnetos are in use, othercontactssuch as'38 may be provided for' engagement by the bar to'short the several circuits'.
For batteryV circuitsa contact 40 may be Y 4Q; provided in the'casing in a. suitable position 'i for Contact with-fthe switch bar when the latter is in latched positionas showninfFig. 2, to close the. circuit to the engine The bar is thus 'adapted to swing awaytro-m the contact to break the circuit when released from,
the lever latch and move'd'vby the plunger.
The contacts comprise pins mounted in in;
' sulating bushings inv the casing, and having rounded heads protruding into the casing at? chamber onto and from which the bar may r.sl-ide easily; Y
Y A coil spring 41 isturther preferably provided on the pin 22 between the bar and the k cover to urge ,the switch bar into close con- Y ductive relation with kthe contacts.
The adaptation ofthe invention for use with, apparatus including a battery ignition system as illustrated in Fig. 4, wherein a ciri ciiit grounded in the engine trameV at 42 includes a vtimer 43, an ignition coil 44, a spark plug 45fconnected to the coil, and a battery 46, a wire47 leading to the contact 40, and the switch bar 2l is grounded in the casing ,55t bythe pin 22 as` indicated at 48 for closing the circuit through the lever l2fand wire 15 to the engine trame. Y 1
In using the device on a motor boat, the operator retracts the throttle lever and inci dentally retracts the plunger, whereby the cooking pin swings Vthe switch bar into positionvtQ permit. the ignition system yto operate, the switch bar latches lthe plunger and the releasinglever latches the switch bar. The throttle lever may then be operated to open and close the carburetor without disturbing the plunger or switch bar. Should the operator be thrown from the boat, the result-ing pull on the string will cause release of the switch bar and permit the plunger to be moved :forward by the spring to move thethrottle lever toward a 'carburetor closinoa osition ductive relation with said contact, and barv Vlatching means including a -springpressed plunger controlled by said throttle lever and a pivoted latch controlling said plunger.
