To all whom it may concern." 7

Be it known that I, RQ MAN ODELL,31 citizen of the United. States, residing at- Chicago, in the county of Cook and State of Illinois, have invented certain new and,

useful Improvements in Starting Means for Hydrocarbon-Engines; and I do hereby declare the following to be a full, clear, and exact description ofgthe invention, such as will enable othersskilled in the art to which it appertains to makeand use the same.

This invention has for its object to provide simple, efficient 1 and easily operable means for starting the multi-cylinder hydrocarbon motors of automobiles withoutnecessitating the driver leaving his seat, and consists in the features of construction and combinations of parts hereinafter fully described and Claimed.

In the accompanying drawings illustrating this l I lVQIitlOIli igure' -1 is .a top plan viewof a four-cylinderhydro-carbon motor equipped with starting means con structed in accordance with my invention.

Fig. 2 is aidetail vertical section of a. compressor employed. Fig. 3 is a top plan view oft he compresso'r and carbureter and shows the gear ng of-the compressor to a crank shaft ]ournaled 1n a bearinglm'the dash-board, the latter being 'shown 'in 'sec-' .tion. Fig. is a side elevation of the said gearing.

In order tostart a hydro-carbon motor it is primarily necessary to introduce into one or more cylinders, a compressed chargev of carbureted air, which, upon ignition explodes andthus produces an initialstroke of sufficient force to give the requisite impetus to the. balance wheel to repeat the carbureter and compressor, also-showing operation which is erie-rally first performed by turning the drive shaft with a crank.- The latter operation requires theexercise of considerable strength and necessitates the chauffeur leaving his'seat. The strength required is generally greaterthan is possessed by women, and consequently the latter are frequently unable to start an automobile without the aid of a man.

render the starting of the motor not only very easy, but further, to enable the start ing means to be operated from the seat of the automobile and thus avoid the necessity of the driver stepping out frequentlyinto muddy roads'in order to perform the op-' eration.

My invention comprises means whereby a compressed charge of carburet'ed air .is simultaneously introduced into all the cylinders of a multi-cylinder hydro-carbon mo tor by means of a small easily operated pump having compression chambers-corresponding in number with the cylinders and each connected with the compression and explosion chamber of one of" said cylinders whereby all cylinders in which the'pistons 'are' not in exhaust position receive a compressed charge, the pressure of the latter being in exact proportion to the size of the respective. compression chambers dueto va rious positions of the pistons therein; Consequently'upon sparking one of said charges,

it 1s. ignited and insures the compression and'lgfiltlOIl of at least a secondcharge so introduced and thereby positively insuring the continued operationof the motor as long as desired.

ware that the introduction of a motor itself, is not'entirely novel, and my in vention resides therefore in arrangement involving a single operatlng device for a carbureted air is introduced into all com- 'multi-cylinder motor'whereby a charge of pression chambers in which the pistons are I in the proper positions to impart the initial strokes necessary to start the motor into con tinuous operation;

Insaid drawings the compressor -1, which is in the instance illustrated, is of the 001- lapsed flexible tube type carrying'tubes 2- corresponding in number with the cylinders of the motor 3'which in-this instance are four in number; The said tubes 2 are disposed parallel with each other in the concave portion of the plate lwhich is disposed concentric with the bearings of the shaft 5 of parallel disks or wheels 6. The latter are connected with eachother at regular-intervals adjacent their peripheries by the cross rods 7 on which rollers 8 are 'revolubly dis- My invention has for its main object to posed, the latter travelingover and comwith the carbureter't) connected with the pletely collapsing the tubes 2, the latter exsupply of hydro-carbon liquid by means of the pipe 10 controlled by the valvell, and

at its discharge end is connected with the compression and explosion chamber of one of said cylindersby means of thepipes 12, 1

13, 14 and 15 respectively. Each of said pipes l2 to 15 inclusive, is equipped with a valve or stop-cock 16 and a check valve 17 the'latter being disposed between the valve 16 and the point of connection of the pipe with the cylinder, the latter connection being preferably effected by means of a T, one arm of which communicates with the cylinder through the outer end wall thereof latter simultaneously with the valves 16. I

The carbureter 9 employed is additional to the carbureter feeding the motor while 'in'operation, and is supplied. for the reason that the 'carbureted air introduced into the compression must be saturated in order to.

supply sufficient vapor to the .air or products of. combustion contained in the 'motor' cylinders to insure combustion in the latter and to effect this throughthe carbureter feeding themotor, would necessitate readjustment of the latter to an extent which would seriously interfere with properoperation of the motor. The shaft 5 of the disks or wheels 6 is suitably. geared to the crank-shaft 22 journaled in a bearing inthe said dash-board, the, crank 23 thereof being disposed within easy reach of the chauffeur.

My devicemay be disposed in any available space adjacent the motor and operatesin a very simple manner as follows: The motor being inert, the chauffeur first'adjusts his motor controlling lever to very low speed and then turns the crank 23 thereby. operating the compressor, the valves 11 and 16 being open, The compressortakes its supply through the carburetor 9, the latter being so constructed as to'saturate the air passing therethrough with hydro carbon vapor.

Said saturated air is fed continuously into the compression chamber of all cylinders and enriches the air, orproducts of combustion contained therein to an extent which renders the latter combustible. In afour cylinder motor, one piston and the valve controlled thereby is always in exhaust position, hence, the carbureted. air entermg said cylinders merely pass through but leaves a charge therein. Another cylinder is in position to ignite the charge upon closing the igniter circuit and the two'remaining pistons are approaching the respective positions of those already mentioned. After rotating the crank '23 a few times, the chauffeur adjusts his motor controlling lever to medium speed and then closes the igniter circuit thereby exploding one charge, and the impetus thus given the motor causes at least one other charge tobe exploded in proper succession after the first and this insures operation of the motor. The rod 19 is then moved to close the valves 11 and 16 .thus. preventing flooding ofthe carburetor 9 andconsequent Waste of hydrok carbon liquid.

The crank 23 occupies very little space and by reason ofthe small diameter of the tubes '2 is so easily operated as to bring it within reach of a young girl. Any other conven ient form of multicylinder compressor may be employed without departing from my invention.

I desire to direct particular attentlon to the carburetor 9, which as stated, is so 0011 structed as to completely saturate the air -with hydro-carbon vaor: "This, I have found by long and care 111 experiment, to be absolutely essential to successful 0 eration,

the carburetors generally employe to feed hydro-carbon motors being totally-inadequate to produce a sufliciently enriched carbureted' air. The said carbureter forms. the subject of a companion application filed simultaneously herewith.

- I claim as my invention:

1. The combination of a multiscylinder hydrocarbon motor, an auxiliary carburetor, a compressor having a plurality of chambers, one'foreach cylinder, an operating device adapted to cause the simultaneous, contraction of the chambers ofsaid compressor,

assa 'es connectin each ofsaid chambers with said carbureter and with its respective -motor cylinder, and mechanism for impartmg motion to said' device-for forcing carbureted 'air intoall 'of the motor cylinders simultaneously.

2. The combination-- of a multi cylinder hydrocarbon-motor, an auxiliary carbureter,

a lurality. of compressors, one forfeach cylin er, a-rota'ry operating device comprising a plurality of parts adapted successively to cause the simultaneous contraction of' the chambers of said compressors, passages connecting each of said chambers with said carbureter'and with the respective motor cylinder, andmecha'nism' for causing the rotation of said'operating device.
