Be it known that I, FRED N. LIVINGSTON, a'

citizen of they United States, residing' at Starters; andl do hereby declare'the following to be a full, clear, and exact descrip.v

. tion'V of the. invention, such as will enable others1 skilled in the yart to .which it appertains to make and use'. the same.;`

This invention relates to improvements in starting apparatus for automobile motors.

Various expediente have. been" devised for the starting ofthemotors of automobiles, but in the majority of instances these starting devices 'have pr'oved ineective. for the purposes for which they have been designed. In the producing of these starting devices, many of the `same have been in the form of attachments more or less complicated in their nature, and because ofthe number of parts involved in their construction, and,in some instances, the use of springs, .they have involved. considerable ,expense for their manufacture and application to selfpropel# ling vehiclesr 1 l f y n The present vinvention has invie'w the provision of means for starting the motors of automobiles by the initial application yof a1 charge of the gaseous mixture einployedl'for the operation ofthe motor in its normal runningcondition, thus dispensingwith the employment of devices` separate and distinct from thel motor` itself, vand enabling 'the'v motorto be 'started from the seat of they machine without the necessity of the operator thereof leaving theseat.

further objectof the invention is Yto provide apparatus of the 4rcharacter referred to by means of which-a starting. charge of the gaseous mixture maybe introduced to apair of the 'cylinders of a motor,- wlienthe latter .is of fouror more cylinders,'without,'liow ever., such a charge being) fired until such is desired bfy the operator of the machine, means being lprovided to interruptfthe circuitv connections of@ the electrical .ignition system prior to the time ofthe injection of the cliargeinto ,the cylinders, thereby guard# ing aga-inst raccident, and the Sametime.- conserring the initial explesive charge until the proper quantity thereofV has been ad-V mitted. i

A further object of the present invention is the provision of firing apparatus of the character stated, the construction of which `is such that the initial explosive charges may be introduced to the cylinders in the proper fgiiantitj. kand then fired by the manipulation ofbut a singler lever,.this construction presenting the advantage of reducing the con-v trollinggpart to a minimum, andA adding but slightly/tothe controlling devices now posi- .tionedupon and adjacent to the seatof the machineoperator.

Other objectsand advantages of the iinpiovements will appear as the nature of the invention is' better understood, the invention consisting substantially in the novel. Aconstruction, combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and pointed out inthe appended claims.

valves 7, typical of automobile motors, said valves being operated by the conventional levers 8 and 9. rlhe cylinders, moreover, are provided also with the usual intake 10 leading from a manifold 11, which latter is connected to a carbureter 12 in the usual way. The exhaust valves 7 discharge into the usual exhaust pipe 13. These parts are merely referred to for clearness of understanding of the relation of the present invention to the conventional motor.

As before stated, the present invention contemplates the provision of means for introducing a starting charge of fuel to the cylinders of the motor, the particular cylinders, however, into which the charge is in- `jected being controlled by the position of the auxiliary valves to be hereinafter described. To the accomplishment of this end a pump 14 is associated with the motor, and is connected to the carbureter 12 by means of a pipe 15, in which is arranged a check valve 16. rlhe pump 14 may be of any usual construction, but is preferably of the type in which a reciprocatory plunger or piston is arranged, said piston being operated by means of a crank 17 having engagement with the piston rod of the pump by means of a connecting link 18. The pump 14 is provided also with a discharge pipe 19 having a check valve 20 arranged therein, and said pipe 19 is connected to a manifold 21 from which lead a plurality of feed pipes 22.

Each of the feed pipes 22 is connected to one of the cylinders of the motor, communication between each cylinder and its feed pipe 22 being controlled by an auxiliary valve 23. Each of the valves 23 is actuated by a rock lever 24` Said'lever being operated by means of auxiliary valve rods 25, which rods are slidably mounted in guide lugs 26 arranged at the exterior of the cylinders. lnterposed between one of said lugs 26 and a collar 27 on each of the rods 25 is a coil spring 28 by means of. which the respective valves are held to their seats.

The crank 17 is arranged at one end of an operating shaft 29. which shaft extends transversely of the frame of the motor, and at the end of said shaft opposite to that which the crank 17 is connected is arranged a hand lever 30. This hand lever extends through a guide frame 31, at the outer side of which is formed a notch 32 in which the lever 30 is normally seated, and thus locked against movement until pressure is applied thereto. For holding the lever 30 in the notch 32 a coil spring 33 is connected to said lever and to a suitable post 34 on the guide 31, which spring exerts its tension normally to draw the lever 30 into the notchY 32. At the opposite side of the guide 31 is a notch 35 into which the lever 30 may be forced against the tension of said spring 33, and

when so introduced such lever is positioned for igniting the starting charge as will be presently explained.

The inlet valves 6 and outlet valves 7 are operated by means of the usual valve rods 36 and 37, respectively, said rods being given reciprccation by means of cams 38 and 39 carried by a cam shaft 40 connected by gears 41 to the crank shaft 42 of the engine, in the usual manner. The valve rods 25, however, of the auxiliary valves 23 are actuated by means of a Slide rod 43, said rod carrying a plurality of cam sleeves 44, one of which is provided for each of the motor cylinders. These cani sleeves are more clearly illustrated in Figs. 8 and 9, and by referring to these views it will be noted that each of the cam sleeves 44 is slidably mounted in relation to the rod 43 through the medium of pins 45 carried by the rod 43 and passing throughslots 46 in the sleeve. Coil springs 47 are associated withthe cam sleeve 44, said springs bearing against one of the pins 45 and the opposite end of the slot 46 in which the pin is seated, and by means of said springs 47 a yielding connection is afforded between the cam sleeve and the rod 43. Hence if the sleeves 44 are unobstructedin their movement they will be actuated simultaneously with the rod 43, but if they be checked in their movement. under conditions as will presently appear, said sleeves remain stationary while the rod 43 may readily slide, the springs 47 of the cam sleeves 'which are locked against movement being compressed under the movement of the rod 43 at this time. y

Each of the sleeves 44 is provided at one end with a cam lug 48, said lugs being arranged at the upper sides of said sleeves, and at the opposite sides of the latterthey are provided with spaced shoulders 49 designed to engage locking lugs 50, one vof which is carried by each of the valve rods 36 and 37. When the valve rods 36 and 37 are moved upwardly to a sufficient extent by their respective cams 38 and 39, the locking lugs 50 are projected into the path of the shoulders 49, and when so positioned the shoulders 49, on the forward movement of the rod 43, will engage said locking lugs, which lugs will prevent forward movement of the cam sleeve 44 under these conditions. Hence, the cam lugs 48 are locked against movement beneath the auxiliary valve rods 25, so that these valve rods remain inactive, their respective valves 23 remaining closed. It will be understood, however, that the movement of the auxiliary valves 23 is properly timed so that certain of these valves will be open while the others are closed, and in the cycle of movements incident to the operation of the motor, the auxiliary valves 23 of the respective cylinders will be openedat proper times to permit the ini'eeten 0f aetettng ehetse Whenever sieh' Therefore, as the explosive charges ,are ad' mittedv te the f reepeette Cylinders these Cheeses de eet esente-:tement :the een ery valves'23, but ,arcmconipined in ythe and successively ,ignited in the ,cycle ,of ltleremente neelent te. the Werking ef the motor. A

To impart the requisite moyement tothe rod .43 in,k a. y forward direction ,rod connected to a bell-crank lever l5l, pivoted to the frameof the motor at ,the rear ,end thereof, a pin-andv-slot connection 52 being employed .between 'the bell-crank leyer 5,1 and the rod 43, and the free end `of said lleyer 51 cooperated with a. cam 53 lwhich is carried by the operating shaftA 29.` "When .the operating shaft 29 is actuated for the operation .the pump 14, the cam 53y swings the bell-crank lever l51 upon its fulcrum and in this movement the rod 43 is projected forwardly. This operation occurs ,When .the handle 30 is moved in a rearward direction in the -`guide, 31, or pulled ytoward $11.6 operator ofthe machine'as the operator is seated therein. `When, however, the handle 30 is moved' forwardly and the cam 53resumes its normal position, a spring 54, which isr arranged at =the forward end of the nod 43, andfis interposed between a stationarylug 55 on the motor frame and a collar 56 -carried by the rod 43, forces said rod ina rearward direction, the spring 54 becoming compressed when the'rod 43'is projected forwardly. Thus, the rod 43 is automatically returned to a position which removes the cam lugs 48 from beneath, the auxiliary valve rods 25 on the rearward movement of the rod 43, and those auxiliary valves 23 which have been opened become closed.

The mechanism thus far described provides means for permitting the starting charges yto be introduced to the respectiye cylinders of the motor. Afterbeing sointrodnced, it is necessary, of course, that the charges shall be properly and timely eX- ploded, and to provide for this mechanism now to be describedv is employed.

In this connection it may be noted that'the present invention contemplates the use of igniting means which is Yassociated with the timer of vthe motor, and referring to Figs. 4, 5 and 6 this ignition means Will be clearly understood.

For th nfrreee .of aetuetesthe neet 67 in manner which has just been described an operating rod 69 is employed, the foi`- Ward end of ,said rod being provided ,with a deflectedfoot 70 which engagzres the post 6T. The rear end of said rod is connected to a bell-,crank lever 1, fulcrumed upon the motor frame and having its free end,V pivotally connected to slide rod 72, the flatter eX- tending transversely 0f the motorframe., andk being urged in one direction by means of ya coil spring l73, interposed bet-Ween a supporting bracket arm 74 wherein 'the rod 72 is slidably mounted and a collar 75 carried by the rod 72, The normal tendency of the Spring73 is to retract the rod '69 so that the deeeted feet.

to expand, and thus remove the vcontacts from engagement with the contact finger 57 r'he rod 72, however. is desiened'to be moved in opposition tothe movement 'induced by the spring 7 3 by the manual operation of the hand lever 30, to which end-said lever 30, when the latter is ,opposite to the rod 72 and thereby in a position to engage the same, may be moved into the notch 35, and in this movement the rod'72 is caused to swing the bell-crank lever 71 upon its fulcrum and thereby project the operating rod 69 in a forward direction. In this movement of the rod 69 the deflectedY foot 70 wipes over the post 67, forcing the latter inwardly against the pressure of the spring 6K6 and thereby positioning the contacts 65 in engagement with the finger 57. Y Upon pressure being released from the hand lever 30 said lever is returned to vthe notch 32 by the spring 33 and pressure being released from the rod 72, the spring 73 reasserts itself, and in this movement retracts the operating rod 69,

whereupon, pressure being relieved from the post 67, the spring y66 forces said post outwardly and again frees the contacts 65 from engagement with the finger 57.

1t frequently occurs in the operation of automobile motors that when the same comes to rest the contact finger of the timer remains upon one of the stationary contacts with which it cooperates for producing a spark. Manifestly, undei these conditions, the injection of a starting charge of fuel into the cylinder the contact of which is in engagement with the finger 57 would cause a premature ignition of such starting charge. To obviate this the present invention contemplates the employment of a suitable cut-out for interrupting .the sparking circuit preliminary to the introduction of the starting charge to the cylinders. For this purpose a forked lever 76 is pivoted to a supporting bracket 77 carried by the niotor frame, the lever 76 and lthe ybracket 77 being electrically connected' to said frame. The lever 76 is provided with acontactlug 78 which coperates with a contact'inger 79 to which one terminal 80 of the electrical circuit is connected. Obviously, the contact finger 79 is insulated from the supporting bracket 77, so that when the lug 76 is freed from engagement with the linger 79 the electrical circuit is opened at this point. On the other hand, as soon as the lug 76 is moved into engagement with the linger 79 the circuit is closed and upon the proper operation of the timer a spark is produced in the motor. One end of the forked lever 76 is arranged in juxtaposition to the crank 17, and `is adapted to contact with the latter', the other end of said lever 76 being arranged in proximity to the end of the rod 72 opposite to that with which the hand lever 3() contacts, so that when said rod 72 is opere' ated by the han'd lever 30 said rod contacts with the forked Vlever 76 and the lug 78 thereof is brought into engagement with the linger 79. By reason of the construction which has just been described it willbe understood that on the movement of the crank 7 in a rearward direction or toward the seat of theoperator of the machine, said crank actuates the forked lever 76 to open the igniting circuit at the linger 79 and the contact lug 7 8. On this movement the pump 1st is filling with the explosive mixture, and none of the latter has been discharged into vthe cylinders of the motor. Therefore, with the igniting circuit opened in the manner described on the forward movement of the crank 17. and the resultant forward movement ofl the pump piston, the starting charge is injected into the cylinders without liability of ignition.

1n the operation of the hereindescribed starting apparatus, `it is assumed that the pistons of the several vcylinders of the motor stop at a point substantially midway between the ends of their strokes, which is generally the case when automobile explosive motors come to rest. 1n such position the pistons of two of the cylinders are ready to start upwardly, while the other two will move downwardly upon the starting of the motor. As illustrated in Figl 3, the piston of cylinder 1 is about to move upwardly on the exhaust stroke, the exhaust valve being opened; the piston of cylinder 2 is moving'downwardly on the power stroke. The piston of cylinder 3 is likewise moving downward on the suction stroke, the inlet valve being open, while the piston of cylinder '-1 is moving upwardly on the compression stroke. In cylinders Qand 4 both of the valves are closed, and it is assumed that the pistons come to rest on the strokes referred-to but at the midway position between the ends of their strokes. This being the case, and it is desired to start the motor, the operator of the machine while remaining in his seat, grasps the hand lever 30 and gives yit alateral thrust to remove the same from the notch 82. By pulling on the lever 30 in a rearward direction, the piston of the pump 14 is drawn rearwardly, thereby creating a suction within the pump and vunder the influence of this suction a charge of the combustible mixture is drawn through the pipe 15 from the carbureter 12 into the pump, and is held therein by the check valve 16. As previously described, this rearward movement of the pump piston, and the corresponding movement of the crank 17, opens the ignition circuit atA the contacts 76 and 79. Forward pressure is now applied to the hand lever 30, and the piston of the pump 14 responds with aforward movement, the explosive charge being thereby expelled from the '40) into the notch 35 thereby being brought pump' 14 through the check valvej 20 and pipe 19 Ainto the' manifold 21" and. is disi tributed by the latter through' the feed pipes tofthe respective auxiliary" Valves 23;- Be'cause of the fact that'- the; eXhafust valve 7 "i cylin'derl and the inletl Valve of cylinder'- are* op'en'- at* their respec tive r`od's 361 andi 37, being'L raised.; by'. the" cams: 38i and 39; the locking1 lugs'Of oi'y thesef particular valve rodsare in such p'ositionlasto Contact with vthe shouldersfLQf of? the; cam sleeve'si lli associated Withl these" particular cylin'dersi -Hence since4 the cam 53 rotiJtesi withv the shaftQQyWheu thelatter is actuatedlby the hand'il'ever 80th` cain: sleevesfktof cylindersv 11' and? are lcle'd againstifrward movement'.VA This results; in' the auxiliary valves-123i of? these' particular cylindersore-l mainingclos'ed7so thatg thefstarting charge is unable to gain admission to the 5cyliiide-ns 1 and 3.
