To all 'whom t may concern:

Be it known that l, Wmran lli, Wnnnm,

a citizen of the Uni Staten, r v at Davenport, in the county ot Scott and lotate ot loira, ve invented certain new and neeful Improvements in Intel-Combustion Engines, ot which the follow is a sp cation.

lily invention relates to equipments for intel eombunion engines.

@ne ot the objects of my invention is to provide means whereby to automatically adjust the appurtenant devices and apparatus necessary for, and incident to the proer operation of -an engine, to rodnce the liest resulte when being sta by means that become operable when the speedo the engine has fallen belov7 a. predetermined velocity, as when the engine is being stopped, and to automatically readjuet said appurtenant devices, and apparatus, consist ent `with the best operation of the engine at a critical speed, at which constancy oi' operation is desired to be maintained, at or before the time when such speed has been attained.

Other and further objects ot my invenY tion will become readily apparent to persons skilled in the art, from a cnneideration of the following description when taken in conjunction with the drawings, wherein l Figure l. is a side elevation of a fragment of a typical engine, showing the associated appurtenances. Fig. 2 is' a side elevation, viewing the. other side. Fig. 3 is an end view ot the engine. Fig. t ie a section teken on line 4--4 of Fig. 2. Fig. le a vertical, central section taken through the carbureter, and Fig. 6 is a vertical section taken through a supplementary fuel oontainer and alarm initiating device.

' ln all the views the name reference characters are employed to indicate similar parte.

ln the excmplilication 'which l *have chosen tor the purpose of illnetratingg my invention, 10 is a typical engine of the intornai combustion type, shown in driving relation with a. dynamo 1l by menne of a chain or belt 12.

13 is a speed responsive governor, and ll ie a carburcter of typical type.

A incl reservoir 'lo contained in the base of the engine ie connected to a nnpplerncn tary reecrvoir lo by n pipe ll.

l? is a tnel pump operated from a crank arm 18 by a rod i9. "lfle crank arxn i8 is connected to a valve operating rocker arm Q0. The pnrnp il' is connected with the carbureter lll by means ot a Tripe 2l and an overdose pipe 22 is connecter with a receptacle 23 that lian connection, by pie 24, to thek supplementary recervoir lbf. li means et the pump tine fuel in maintained in the carburetor at constant level tor the proper operation thereof.

The engine is provided with an outwardly seating compression relief valve normally held closed by the spring 24:, an When said ring issnot dominated by other innences.

spark-time-controlling mechanism Q5, com rises a rotatable part 26 rotated by the sha t 27 in time relation with the movement of the piston, and a relatively oecillatable part 28 capable of oscillation by means of the rod. 29, The oscillation o the part 28, with reference to the rotatable part 26, varies the time that the spark is made in the cylinder with reference to the power orcompression stroke of the piston.

' The carbureter lll is provided with a laterally projecting air chamber 30 containing on electro-thermic air heating coil 3l. This coil is adapted to be contained in an electric circuit and to be heated by the Acurrent thereof, so to Warm or heat the air that passes into the cnrliureter at the time when the engine is cold and is about to be started.

A switch comprising a blade 33 pivotetl, an at El, to a etnn'darcl 35, is adapted to short circuit the air heating coil 3l, when the movable blade 33 maken contact with the blade Sli lll'ire 37 in connected to wire 38, the latter being connected to the blade of 'the switch' and also connected to one end of the heating coil 3l, the other end of the heating coil being connected to an insulating block 31 se cured to a part of the-carburetor. Wire 39 A in supported by said block and connected to the terminal nl or the coil 3l, as by a bolt 39C A wire l0 is connected to the blade 36 of the switch and to a suitable souxce of electric current supply. -Wlien the switch 32 in cloned the air heating coil 31 short circnitcd by the wire 38, and blade 33, the current coming in on the Wire 37, passing .over the wire 38, throu h the pivoted switch blade 33, to the other cad Wire t8, thereby elicit circuiting the heating coil. The piv oted switch blade 33 is connected to a pivot` ed lever` 41 which is pivoted to a standard 42, as at 43, the other end of the lever 41` being connected to a lever 44, as at 45. The lever 44 is fixed to a shaft 46, as atV 47. The shaft 46 is adapted to be rocked on Vits bearings 48 and 49 by means 0f the speed responsive fly ball governor 13. The shaft 46 1s normally held, in the positionshown in Fig. 3, by mea-ns of a spring 50 secured toa fixed art of the engine and to an arm 51 that is xed to the 'shaft 46, as at 52. The

speed responsive governor comprises weighted arms 54 and 55, pivoted as at 56 and 57 respectively, and yhaving `extended angularly disposed arms 58 and 59, respectively. A push yrod 60 has bearings in the yoke piece (ifwhichis secured topthe power wheel62 carried onthe engine power shaft 63.

Secured to the rock shaft 46 1s a laterally and vertically extending arm 64 which normally bearsagainst the push in 60. When.

end of the lever 41 isl depressed and thereby the switch 32 is closed'. Secured to the lever 44 is a vertically extending rod 65 carrying upon its upper end an adJustable cross piece 66. This cross piece bears upon the stem` of the compression relief valve and when the lever 44 is in the position shown in Fig. 3the spring being'stronger than the spring 24 of the relief valve the latter spring is com ressed and the' relief valve opens so that w 'en the engine is started, as when` it is initially operated Vby t e electric motor 11, there is a into the heating coil 31, thus heating theair/j 4 that maybe drawn'into the carbureter' '14 and therebyfacilitating the admixture of the air andthe hydro-carbon fuel such as gasolene or gas that may be taken into the cylinder to be subsequently compressed and ignited to provide the necessary power impulse to be effected by the engine.

The lever 44 is depressed, by operation of the spring 50, and therefore the vertical rod 65 carrying the cross piece 66 is in its lowest position and the stem of the compression relief valve is pushed downwardly against-the spring 24, thereby reducing the compression m t e cylinder'of the engine and rendering the engine more easily to be started, and the rod 29 which is ivotally connected to the pivoted lever 41, s ifts the spark time device so that the spark will be made within the cylinder to i 'te the charge at a time delayed, with re erence to the reci rocation of thepiston, beyond that at whic it would occur when the engine is running at its normal speed,and the electromagnet 75 isenergized by the current that is used to energize the electric motor so that the lubricating oil may bed/istributedi t'o-the minimumfof compression to'be'overcomesin.--necessarymoving'lpatbf the engine for the cylinder of the engine,l by reason ofthe action of the relief valve.

The'auxiliary fuel reservoir -16 contains a float 67 having a vertically extending stem 68 that passes freely through the top 69 and .carries upon its upper 'end an adjustable 4ist , engine fuel is about exhaus J Y i 78 isa reservoir for lubricating oil for lubricating various parts of the engine, the 65 metallic disk 70. The height of the disk fromv the top is a visual indication of the supply of liquid fuel 71 that may be contained within the reservoir. When the su ply becomes low., or about exhausted, t e float 6 7 follows the liquid level down in the reservoir until the disk 70, 4carried by the stem 68, makes electrical connection with circuit terminals 71 and 72, thereby closing an electric circuit containing n alarm bell 73 and a battery 74 over the wires 75 and 76. The bell is-preferablylocated at some point remote from the plan. and serves as a means for warning the atidant thatthe valve of which is normally closed but the purpose of lubrication andthese parts will remain in the condition described until the engine becomes self propelling, or until its shaft has attained a predetermined speed, at which time the Hy balls 54 and 55, of the speed responsive governor, will fly outwardly and cause the push in 60 to be moved outwardly and to latera y move the vertical arm 64, which is connected to the shaft 46, thereby raisin the pivoted lever 44 and causing the relie valve to close, and raising one end of the pivoted lever 41,' causing shifting of the 'spark time mechanism to a position consistentwith the higher speed of the engine, and closing the switch 32, thereby shutting the electric current out of the air heating coil 3 1, as now it will no longer be required, andthe engine'is constopped, thel spring 50'will cause thef-push 130 Lisanne all of the apparatus will be automatically returned to the positions shown in the drawings, which they occupy when the engine is not in active operation. It will therefore be seen that all of the appurtenant devices necessary for cooperative association- With the engine, are automatically adjusted to meet the conditions for the best operation of the engine so that the engine may be started by the electric motor With the least resistance and at the highest eiiciency, and so as to meet the changed conditions of the engine, after it has become self propelling, necessary for its eicient operation at a higher or normal speed.

While l have herein disclosed a representation of the embodiment of my invention, it is evident that changes may be made in the arrangement and disposition of the parts, Within the scope of the appended claims, Without departing from the spirit of my invention.
